9 incorrectly start @PJL commands without a language
10 escape (STR #734)
11 - Miscellaneous build fixes for NetBSD (STR #788)
12 - Added support for quoted system group names (STR #784)
13 - Added "version" option to IPP backend to workaround
14 serious bug in Linksys's IPP implementation (STR #767)
15 - Added Spanish translation of web interface (STR #772)

20 - The printer state was not updated for "STATE: foo,bar"
21 messages (STR #745)
22 - Added new CUPS API convenience functions which accept
23 a HTTP connection to eliminate extra username/password
24 prompts. This resolves a previous authentication

27 broadcasts, resulting in missing printers on client
28 machines (STR #754)
29 - The scheduler did not pass the correct CUPS_ENCRYPTION
30 setting to CGI programs which caused problems on
31 systems which used non-standard encryption settings
32 (STR #773)
33 - The lpq command showed 11st, 12nd, and 13rd instead of
34 11th, 12th, and 13th for the rank (STR #769)

48 port other than 443 (STR #730)
49 - The scheduler could crash when processing a Limit or
50 LimitExcept directive (STR #728)

53 a default printer (STR #728)
54 - The PAM checks in the configure script did not stop
55 after the first match (STR #728)
56 - The cups-config man page was incorrectly placed in
57 section 3 (STR #728)

70 - The IPP backend now supports the following options in
71 the device URI: encryption, waitjob, and waitprinter
72 (STR #699)
73 - The parallel, serial, socket, and USB backends did not
74 return a non-zero exit status when a job failed to
75 print in the middle of sending it (STR #715)
76 - Location directives in the cupsd.conf file were
77 case-sensitive for printer and class names, so
78 queue-specific access control was not reliable (STR
79 #700)
80 - cupsDoFileRequest() did not handle HTTP continue
81 status messages in all cases, causing sporatic
82 problems with IPP printers from some vendors (STR
83 #716)
84 - The rastertodymo driver now supports the Zebra ZPL
85 language (STR #713)
86 - The test suite no longer generates a printcap file,

110 CUPS baseline (STR #661)
111 - The USB backend incorrectly reported "media tray
112 empty" (STR #660)
113 - The scheduler did not use a case-insensitive
114 comparison when checking for group membership, which
115 caused problems with Win9x clients printing via SAMBA
116 (STR #647)
117 - The scheduler did not report the addresses associated
118 with certain network errors, making troubleshooting
119 difficult (STR #648, #649)

133 "busy" (STR #617)
134 - The httpGetHostByName() function did not range check
135 IP address values (STR #608)
136 - The httpUpdate() function could return HTTP_ERROR
137 instead of the HTTP status if the server closed the

144 button to set the default printer or class on a server
145 (STR #577)
146 - The HTTP authentication cache was broken (STR #517)
147 - The cupstestppd utility now fails PPD files that have
148 a DefaultOption keyword for a non-existance option
149 name (STR #476)
150 - Optimized the scanning of new PPD files on scheduler
151 startup (STR #424)

157 - The cups-lpd mini-daemon did not reject print jobs to
158 queues that were rejecting new print jobs (STR #515)
159 - Some calls to the ctype functions did not account for
160 platforms that use a signed char type by default (STR
161 #518)
162 - The scheduler could use excess amounts of CPU if a CGI
163 program was sending data faster than the client could
164 take it (STR #595)
165 - Updated the Ghostscript 8.x integration stuff (STR
166 #484)
167 - The lpd backend used a source port of 732 by default,
168 which is outside of the range defined by RFC 1179;
169 also added a new (default) "reserve=any" option for

171 - The scheduler did not check for a valid Listen/Port
172 configuration (STR #499)
173 - The cupsPrintFiles() function did not always set the

176 line if the file began with a PJL escape sequence (STR
177 #574)
178 - The printer-is-accepting-jobs status of remote
179 printers was not sent to clients via browsing or
180 polling (STR #571)
181 - Browse packets did not indicate whether a printer
182 was accepting or rejecting jobs.
183 - The web interface did not show the printer state
184 history information (STR #592)
185 - The rastertoepson filter would crash under certain
186 cirsumstances (STR #583)
187 - The USB backend did not handle serial numbers using

190 #588)
191 - The USB backend did not build on Solaris x86 (STR
192 #585)
193 - The cupsDoAuthentication() function did not use the
194 method name for Digest authentication (STR #584)
195 - The scheduler could crash if a print job could not be
196 printed and the PreserveJobHistory option was turned
197 off (STR #535)
198 - cups-lpd now logs the temporary filenames that could
199 not be opened in order to make troubleshooting easier
200 (STR #565)
201 - cupsGetJobs() now returns -1 on error (STR #569)
202 - Added localization for Belarusian (STR #575)
203 - The LPD backend used the full length of the hostname
204 when creating the data and control filenames, which
205 causes problems with older systems that can't handle
206 long filenames (STR #560)
207 - The scheduler did not refresh the common printer data
208 after a fast reload; this prevented banner and other
209 information from being updated (STR #562)
210 - The scheduler did not send common or history data to
211 the client when processing a CUPS-Get-Default request
212 (STR #559)
213 - The httpFlush() function did not always flush the
214 remaining response data in requests (STR #558)
215 - The scheduler could complete a job before it collected
216 the exit status from all filters and the backend (STR
217 #448)
218 - The PPD conformance tests did not catch group
219 translation strings that exceeded the maximum allowed
220 size (STR #454)
221 - Updated the client code in the scheduler to close the
222 client connection on errors rather than shutting down
223 the receive end of the socket; this caused resource
224 problems on some systems (STR #434)
225 - cups-polld didn't compile on Tru64 5.1B (STR #436)
226 - "lpc stat" crashed if the device URI was empty (STR
227 #548)

229 - std:floor() cast needed on IRIX 6.5 with SGI C++
230 compiler (STR #497)
231 - cupsRasterReadPixels() and cupsRasterWritePixels() did
232 not handle EAGAIN and EINTR properly (STR #473)

242 (STR #408)
243 - The web interface could lockup when displaying certain
244 URLs (STR #459)
245 - The PostScript filters now convert underscores ("_")
246 to spaces for custom classification names (STR #555)
247
248
249 CHANGES IN CUPS V1.1.20
250
251 - The pstops filter didn't properly handle collated,
252 duplexed copies of documents with an odd number of
253 pages on printers that did not do their own collated
254 copies (STR #389)
255 - Tru64 doesn't define a prototype for hstrerror() (STR
256 #430)
257 - Updated the pdftops filter to use the annotation flags
258 instead of the subtype to determine whether to print
259 an annotation (STR #425)
260 - The French web interface localization did not use
261 absolute paths for the navigation bar (STR #428)
262 - The CUPS test suite did not undefine the PRINTER and
263 LPDEST environment variables. This could lead to bogus
264 test results (STR #380)
265 - The cupsLangDefault() function now works if you don't
266 have the base OS localization installed (STR #418)
267 - The pdftops filter no longer needs to create temporary
268 files with tmpnam (STR #406)
269 - The HTTP code did not use a case-insensitive
270 comparison when checking for the Basic authentication
271 method (STR #407)
272 - The httpEncode() function always added a trailing "="
273 character, which is not required by the Base64
274 encoding specification (STR #407)
275 - The signal handlers did not need to call sigset();
276 this caused a recursion problem on some versions of
277 IRIX (STR #422)
278 - Moved the scheduler termination code into the mainline
279 to be consistent with the way other signals are
280 handled (STR #423)
281 - The cupsaddsmb program didn't export the new CUPS
282 driver for Windows properly (STR #390)
283 - The ppdOpen() functions did not issue an error when a
284 translation string exceeded the maximum allowed by the
285 Adobe PPD specification (STR #399)
286 - The default landscape orientation was not the same as
287 that defined in the PPD file (STR #397)
288 - Updated the pstoraster patch files and CUPS driver to
289 work with Ghostscript 8 (STR #402)

292
293
294 CHANGES IN CUPS V1.1.20rc6
295
296 - "lp -i jobid -H restart" would often return an error
297 even though the job restarted successfully (STR #362)
298 - The scheduler did not check for invalid allow/deny
299 addresses such as "11.22.33.44/24". It now masks off
300 the extra address bits and logs a warning message in
301 the error_log file (STR #337)
302 - The cupstestppd utility now checks for missing
303 ImageableArea and PaperDimension attributes for each
304 defined PageSize (STR #365)
305 - The IPP code did not wait for a reply indefinitely on
306 HTTP connections in "blocking" mode (STR #377)
307 - The web interfaces did not rewrite the default printer
308 URI properly (STR #299 and #369)
309 - The LPD backend passed the C and L commands in the
310 wrong order (STR #378)
311 - The Dymo label printer driver did not set the label

314 99999 (STR #371)
315 - The Visual C++ project files did not work (STR #366)
316 - The scheduler's cupsLangSeek() function did not reset
317 the "EOF" flag, preventing compressed files from being
318 typed properly in some cases (STR #368)
319 - The cupsLangGet() cache was only used if the locale
320 name provided an explicit character set name (STR
321 #354)
322 - The CUPS API convenience functions did not call
323 cupsLangFree() when they were done with the
324 localization data (STR #354)
325 - The scheduler did not return the
326 job-hold-until-supported or job-hold-until-default
327 attributes (STR #356)
328 - The cupsaddsmb program did not support the new CUPS
329 driver for Windows (STR #357)
330
331
332 CHANGES IN CUPS V1.1.20rc5
333
334 - The scheduler did not initialize the browse socket
335 file descriptor properly when only SLP browsing was
336 enabled (STR #259)
337 - The scheduler accessed the job attributes before they
338 were set (STR #347, fix to STR #335)
339 - The cupsCancelJob() function did not return 0 when the
340 job could not be canceled (STR #340)
341
342
343 CHANGES IN CUPS V1.1.20rc4
344
345 - The scheduler did not move the incoming job attributes
346 in the operation group to the job group (STR #335)
347 - The cupsDoFileRequest() function did not check for an
348 early HTTP response while sending the file (STR #314)
349 - The web interfaces did not quote #, ?, or . in printer
350 names, which caused some problems with the generated
351 URLs (STR #320)
352 - CUPS couldn't be completely compiled with the -dDEBUG
353 option (STR #331)
354
355
356 CHANGES IN CUPS V1.1.20rc3
357
358 - More SLP changes (STR #259)
359 - Revamped the child signal handling code to completely
360 avoid deadlock issues on Solaris (STR #325)
361 - The lpadmin command displayed an incorrect error
362 message when the "-u" option was provided with no
363 arguments (STR #313)
364 - The web admin interface did not display an error
365 message if the PPD file could not be loaded (STR #308)
366 - The ppdEmit() functions did not use the correct
367 orientation value position for custom page sizes (STR
368 #292)
369
370
371 CHANGES IN CUPS V1.1.20rc2
372
373 - The serial backend set the IXANY option on the port
374 for XON/XOFF flow control; this caused problems with
375 printers that returned status info but were not ready
376 for more print data (STR #287)
377 - The scheduler didn't support scripted index files
378 (index.php, index.pl, etc. - STR #290)
379 - The scheduler did not correctly localize script files
380 with "GET" variables (STR #268)
381 - Changes in job classification are now logged (STR
382 #289)
383 - Fixed a few more SLP-related bugs (STR #259)
384 - Updated the user/group configure checks for MacOS X
385 10.3 (STR #270)
386 - Fixed an offset bug in the PDF filter (STR #284)
387 - The cupsDoRequest() and cupsDoFileRequest() functions
388 did not map several HTTP status codes to their IPP
389 counterparts. This made detecting certain conditions
390 very difficult (STR #277)
391 - Config, spool, and status files are now owned by the
392 scheduler user (usually root) with read permission for
393 the filter group (STR #283)
394 - The HP-GL/2 filter did not support the SI command,
395 some values for the AD and SD commands, and did not
396 rotate labels properly via the DI command (STR #282)
397 - The fax support did not update/set the job-hold-until
398 attribute when a fax job fails (STR #269)
399 - The cupsLangGet() function didn't support locales of
400 the form "ll.charset" (STR #271)
401 - The scheduler did not use the charset when getting the
402 language localization for a request; this caused extra
403 disk IO for every request (STR #271)
404 - The scheduler did not support requests with more than
405 one language specified (STR #267)
406
407
408 CHANGES IN CUPS V1.1.20rc1
409
410 - The scheduler now waits up to 60 seconds before
411 restarting to allow active jobs to complete printing
412 and pending requests to be processed (STR #226)
413 - The web interface did not work on systems where time_t
414 is 64 bits (STR #262)
415 - Added backend tweeks and content-length check from Red
416 Hat (STR #253)
417 - The USB backend now uses the 8255 constants instead of
418 the standard constants when reporting printer status
419 bits on Linux (STR #254)
420 - Added new cupsDoAuthentication(), cupsGetFd(),
421 cupsGetFile(), cupsPutFd(), and cupsPutFile() functions
422 to the CUPS API (STR #112)
423 - The PDF filter always scaled and offset pages; this
424 caused problems under MacOS X, so now the "fitplot"
425 option controls whether PDF files are scaled to fit
426 within the printable area of the page (STR #250)
427 - The LPD backend did not support the port number in a
428 URI (STR #247)
429 - Some filters didn't properly support boolean options
430 (STR #249)
431 - Landscape PDF files were not always offset by the
432 correct amount when rotating (STR #243)
433 - The scheduler could hang in a call to localtime() when
434 logging messages from the signal handler (STR #242)
435 - The PDF filter no longer prints form widgets; this
436 duplicates the behavior of Acrobat Reader (STR #241)
437 - cupsGetPPD() didn't handle a late termination of a
438 HTTP connection with the server (STR #220)
439 - ppdOpen() did not correctly check for "*PPD-Adobe-4."
440 on the first line of a PPD file. This caused incorrect
441 PASS results for some PPD files (STR #233)
442 - cupsEncodeOptions() did not allow boolean options to
443 use "yes" and "on" for true values (STR #227)
444 - The pstops filter only sent the TBCP exit sequence if
445 it was defined in the JCLEnd attribute in the PPD file
446 (STR #224)
447 - Support for more than 1024 files was broken on Solaris
448 9 (STR #217)
449 - The setgroups() calls now pass in 1 group (the
450 configured group) instead of 0 for compatibility with
451 BSD and Darwin (STR #213)
452 - The scheduler's built-in broadcast throttling was
453 ineffective since incoming packets would cause the
454 next group of outgoing packets to be sent immediately
455 rather than waiting for the next time slot (STR #211)
456 - Added a new ppdSetConformance() function to set the
457 conformance requirements for PPD files. Currently only
458 two levels are defined, PPD_CONFORM_RELAXED and
459 PPD_CONFORM_STRICT, and the default is the relaxed
460 level (STR #212)
461 - The IPP backend did not correctly execute the
462 pictwpstops filter on OSX (STR #210)
463 - The LPD backend did not set the banner class when the
464 "banner=yes" option was specified in the device URI
465 (STR #209)
466 - The imagetoraster filter did not support all of the
467 page device attributes (STR #208)
468 - The pdftops filter incorrectly auto-rotated pages when
469 the user already had specified the proper orientation
470 (STR #207)
471 - Fixed AIX shared library support (STR #201)
472 - Added support for live testing with Valgrind (STR
473 #193)
474 - The CGI programs now collect the list of needed
475 attributes for the class, job, and printer template
476 files (STR #192)
477 - The scheduler now passes the first port that is bound
478 to the local loopback or "any" addresses to the CGI
479 programs rather than the port that the browser
480 connected to (STR #103)
481 - The cupstestppd program now checks for bad
482 JobPatchFile attributes and incorrect versions of the
483 Manufacturer attribute for HP printers (STR #155)
484 - The filter makefile incorrectly installed
485 libcupsimage.a in the filter directory (STR #180)
486 - The scheduler did not verify that the job history
487 files define the job-priority and
488 job-originating-user-name attributes (STR #178)
489 - The pstops filter didn't handle poorly-formed binary
490 PostScript files that had CTRL-D's in them (STR #156)
491 - The ppdOpen*() and cupsLangGet() functions did not
492 make a copy of the old locale strings when using the
493 POSIX locale when reading files, which apparently
494 caused problems with some implementations of the
495 standard C library. (STR #159)
496 - The pdftops filter did not work properly with some
497 embedded Type1C fonts (STR #177)
498 - Updated the pdftops filter to be based upon Xpdf
499 2.02pl1 (STR #191)
500 - The scheduler did not reset the group list when
501 running CGI and filter processes (STR #185)
502 - The scheduler no longer calls malloc and free from the
503 signal handlers (STR #190)
504 - The USB backend now uses the manufacturer and model
505 strings if the description string is not available
506 (STR #174)
507 - The ppdOpen functions still supported the
508 VariablePaperSize attribute, which was removed in v4.0
509 of the PPD spec. This caused problems with PPD files
510 that relocated the PageSize option to a non-standard
511 group (STR #158)
512 - The cups.list file referenced MAN1EXT, MAN3EXT, and
513 MAN5EXT, but none of those were actually defined (STR
514 #147)
515 - Chunked requests could cause a Denial of Service if
516 the connection is terminated before the first byte of
517 chunk data is sent/received (STR #143)
518 - Printers with special characters in their names were
519 not accessible from the web interface (STR #120)
520 - The lpstat command now shows the correct interface
521 script or PPD file, if any, for a print queue (STR #89)
522 - The lpstat command now shows the printer-state-message
523 and printer-state-reasons attributes whenever they are
524 not blank (STR #152)
525 - The French and German option-conflict.tmpl template
526 files did not get installed (STR #148)
527 - The cups.list.in file did not work when compiling
528 without shared libraries (STR #149)
529 - The DSOFLAGS included the LDFLAGS, which causes
530 problems on at least HP-UX (STR #150)
531 - The fax printer support did not keep track of the fax
532 capability bit (STR #144)
533 - The appleLangDefault() function could leak a small
534 amount of memory (STR #145)
535 - The ppdOpen() functions now mirror all normal
536 attributes to the attribute list; previously only
537 certain unassigned attributes would be added (STR
538 #139)
539 - The ppdEmitJCL() function wrote JCL commands to stdout
540 instead of the passed file pointer (STR #142)
541 - The httpGets() function could, in certain states,
542 block waiting for data (STR #132)
543 - The cupsEmitJCL() function not outputs an empty @PJL
544 command after the PJL language escape to work around
545 bugs in certain PJL implementations (STR #131)
546 - The cupsEmit*() functions didn't set the orientation
547 value properly (STR #127)
548 - The cups.spec file didn't list the rc2.d init
549 directory or the cupstestppd file (STR #134)
550
551
552 CHANGES IN CUPS V1.1.19
553
554 - The GNU TLS code incorrectly used
555 gnutls_check_pending() instead of
556 gnutls_record_check_pending() (STR #128)
557 - The ppdEmit() functions output "PageSize Custom"
558 instead of "CustomPageSize True" in the DSC comments.
559 Also, the custom page size code did not use the
560 ParamCustomPageSize attributes (STR #127)
561 - The cupstestppd command did not list the conflicting
562 options (STR #123)
563 - The lpq command did not ensure that there was
564 whitespace between the fields in the job listing (STR
565 #117)
566 - The German web templates had errors (STR #119)
567 - The configure script didn't specify the static
568 libraries properly when configuring with the
569 --disable-shared option (STR #104)
570 - The cups.list file used file dependencies for package
571 formats other than portable, RPM, and Debian (STR #98)
572 - cupsLangGet() didn't use its language cache (STR #97)
573 - "lpq -P" would segfault instead of showing a usage
574 message (STR #94)
575 - Fixed compiler warnings in pdftops filter (STR #96)
576
577
578 CHANGES IN CUPS V1.1.19rc5
579
580 - Jobs with banner pages that were printed to implicit
581 classes would get double banner pages for each
582 file/banner in the job (STR #68)
583 - The mime.convs file was missing the filter definition
584 for Windows BMP (image/x-bitmap) files (STR #85)
585 - The scheduler allowed some READ-ONLY job attributes to
586 be set, which could cause the scheduler to fail on the
587 next restart (STR #82)
588 - The lp and lpr commands did not report when the
589 scheduler was not responding; instead, the user would
590 incorrectly see a "no default destination" error (STR
591 #70)
592 - cupsLangGet() could fail on OSX due to a corrupt
593 language preference (STR #78)
594 - Added more checks for HTTP request timeouts.
595 - The scheduler dropped the first non-alpha character
596 after an open brace when doing attribute substitutions
597 in banner pages (STR #77)
598 - The scheduler child might send SIGUSR1 to the parent
599 before the signal handler was installed; this didn't
600 prevent the scheduler from starting but produced an
601 annoying error message (STR #45)
602
603
604 CHANGES IN CUPS V1.1.19rc4
605
606 - The lp command did not accept "-" for printing from
607 the standard input as required by POSIX 1003.1 (STR
608 #59)
609 - Added the job-originating-host-name information for
610 the page_log file documentation in the SAM (STR #31)
611 - The German web interface templates did not use the
612 right paths for job operations (STR #54)
613 - The scheduler would consume all available CPU if
614 started with a pending job in the queue (STR #35)
615 - The polling daemon allocated an extra localization
616 buffer but did not free it, causing cups-polld to
617 eventually use all available memory (STR #40)
618
619
620 CHANGES IN CUPS V1.1.19rc3
621
622 - The scheduler could get in an infinite loop cancelling
623 jobs using "cancel -u user dest" (STR #48)
624 - The "cancel -u user" command did nothing (it should
625 cancel all jobs on all printers owned by the named
626 user - STR #48)
627 - The scheduler would write 0-length job control files
628 (STR #46)
629 - Updated the French man pages (translation provided by
630 Gilles QUERRET)
631 - The scheduler would delete all printers from
632 printers.conf if a job was active when a HUP signal
633 was handled (STR #47)
634 - The cups-polld program would leak memory if it was
635 unable to send browse packets to the loopback
636 interface (STR #40)
637 - The scheduler did not put the
638 job-originating-host-name attribute in the job
639 attributes group.
640 - The text filter did not default to wrapping text as
641 defined by the IPP implementation document.
642 - Scan backends first, PPDs second (STR #37)
643 - Updated the Netatalk documentation in the SAM (STR #38
644 and #39)
645 - The test suite sent text files to a non-PS print queue,
646 which requires ESP Ghostscript (provided separately).
647 Now send the JPEG test file (STR #33)
648 - The test suite did not show the estimated disk space
649 requirements (STR #33)
650 - The test suite did not set the MaxLogSize directive to
651 0 to prevent log file rotation (STR #33)
652 - The test suite still setup the old CUPS Ghostscript
653 symlinks (STR #33)
654 - The pstops filter did not report the correct number of
655 copies for the page_log file when printing collated
656 copies to a printer that doesn't support them in
657 hardware (STR #32)
658 - cupsLangGet() needs to set the CTYPE locale to "C"
659 (POSIX) to avoid erroneous tolower/toupper values (fix
660 suggested by Bjoern Jacke)
661 - Fixed a typo in the cups.list.in file.
662 - Updated all of the Western European locales to default
663 to ISO-8859-15 (for Euro support, suggested by Bjoern
664 Jacke)
665 - Updated the German message catalog (update provided by
666 Bjoern Jacke)
667
668
669 CHANGES IN CUPS V1.1.19rc2
670
671 - cupsLangGet() now sets the encoding field based on the
672 trailing charset in the locale name, and doesn't look
673 for a message catalog in a specific locale.charset
674 directory. This fixes STR #26 and is more in line
675 with the CUPS 1.2 implementation.
676 - The configure script now aborts if the "ar" command or
677 compilers cannot be found.
678 - The static cupsimage library was not built by default.
679 - The path for the "ln" command was hardcoded in
680 Makedefs.in instead of being checked at configure time
681 (STR #28).
682 - Banner pages containing unescaped { characters would
683 not work.
684 - The printer-state-time collection attribute was
685 encoded as an enumeration instead of an integer.
686 - The printer-is-accepting-jobs collection attribute was
687 was not added to the collection value.
688 - The printer-state-sequence-number collection attribute
689 was not added to the collection value.
690 - Fixed typo and const mismatch in IPP backend.
691 - Updated the man pages for the new configuration
692 directives.
693 - Updated the SAM for MacOS 10.2, the CUPS drivers for
694 windows, the available LPD backend options, and the
695 new configuration directives.
696 - The imagetops filter didn't position images properly
697 on the page (STR #18)
698 - The configure script didn't add CPPFLAGS to the
699 compiler options or LDFLAGS to the DSO options (STR
700 #13)
701 - The scheduler would try to write a debug log message
702 when starting a job that contained a NULL string.
703 Since not all versions of snprintf() support NULL
704 string pointers this caused some problems (STR #20)
705 - The testipp program now supports reading of IPP
706 message files such as those used for the job history
707 in /var/spool/cups.
708
709
710 CHANGES IN CUPS V1.1.19rc1
711
712 - Added CUPS support files for Java, Perl, and PHP
713 (located in the "scripting" subdirectory...)
714 - The scheduler now supports fast-reloads of the
715 cupsd.conf file when it is updated via HTTP.
716 - The scheduler always changed the ownership of log
717 files; it now only does so if they are not in the /dev
718 directory (i.e. don't want to change the ownership and
719 permissions of /dev/null...)
720 - Added libpaper support (patch from Jeff Licquia)
721 - Added a new istring() rule for MIME types files that
722 does a case-insensitive comparison of strings.
723 - The cups-lpd mini-daemon now sends jobs to the default
724 queue when an empty queue name (or "lp" and there is
725 no "lp" queue) is sent.
726 - The scheduler now supports fax queues identified by a
727 "*cupsFax: True" attribute in the PPD file. When a job
728 can't be sent, it is held for 5 minutes by default
729 while other jobs are attempted. The FaxRetryLimit and
730 FaxRetryInterval directives control the number of
731 retries and the time between retries.
732 - The scheduler now preserves the default options of PPD
733 files when modifying/upgrading an existing PPD file.
734 When installing a new printer, the scheduler sets the
735 default media size to Letter or A4 as appropriate for
736 your locale.
737 - The scheduler no longer limits the number of
738 BrowseAddress, BrowsePoll, BrowseRelay, Listen, Port,
739 SSLListen, and SSLPort directives to 10.
740 - The scheduler now supports print files that have been
741 compressed using gzip.
742 - The scheduler used the stdio functions to read any job
743 ticket information in a PostScript print job. Since
744 some platforms limit the number of stdio files to 256,
745 job ticket information was ignored when the server had
746 a large number of clients connected to the system.
747 - Filters and backends may now report the total number
748 of pages ("PAGE: total NNN") to the scheduler.
749 - The LPD backend now supports timeout and
750 sanitize_title options (default to 300 and yes,
751 respectively) and has some additional changes to
752 reduce the chances of multiple copies being printed
753 when only one copy was requested.
754 - Fixed a polygon drawing bug in the HP-GL/2 filter.
755 - Added a robots.txt file to the standard install to
756 prevent search engines from indexing the CUPS server.
757 - Added support for STATE: messages
758 (printer-state-reasons), printer-state-history, and
759 printer-state-time to the scheduler.
760 - When using RunAsUser, the scheduler would initially
761 start any previously queued (pending) jobs with
762 RunAsUser disabled - all backends would be running as
763 root.
764 - If a backend failed for a printer, CUPS would
765 incorrectly requeue the job for printing again.
766 - Added support for IPP collections and files.
767 - Added experimental support for generic CGI scripts and
768 programs, Java, Perl, PHP, and Python to the
769 scheduler. See the file "CGI.txt" for more
770 information.
771 - The CUPS API now supports HTTP cookies and the Expect:
772 field.
773 - The cancel command now correctly supports the "-u
774 user" option to cancel all jobs for the named user.
775 - The Purge-Jobs operation now supports the my-jobs
776 boolean attribute and a new purge-jobs boolean
777 attribute to control whether job history data is
778 purged from the scheduler; the default is false for
779 my-jobs and true for purge-jobs to match the original
780 implementation.
781 - The scheduler would not timeout printers when only
782 using SLP browsing.
783 - If the scheduler was unable to execute a filter, it
784 would try to restart the job indefinitely until the
785 filter could be executed.
786 - When writing BSD printcap files, the scheduler now
787 includes the rm and rp attributes, allowing the file
788 to be exported to LPD clients. [Patch from Dominic
789 Kubla]
790 - The scheduler optimization to reference IPP attribute
791 data instead of performing a full copy caused problems
792 when the referenced data was deleted before it was
793 sent. It now only references attributes that change
794 only when the scheduler is restarted. The change also
795 reduced the memory footprint of a printer object to
796 2k.
797 - The scheduler now holds signals while logging messages
798 to avoid potential deadlock issues when handling
799 signals on Solaris 8.
800 - The lpadmin command now allows printer access control
801 by group name as well as user name.
802 - "lpoptions -l" got in an infinite loop if no default
803 printer was available.
804 - The scheduler now logs the job-originating-host-name
805 attribute in the page_log file, and uses "-" for any
806 empty fields (patch from Dominik Kubla).
807 - The pdftops filter now scales PDF pages within the
808 printable area of the page.
809 - The pstops filter didn't include the page-label and
810 classification boxes when printing EPS or non-
811 conformant PS files.
812 - The imagetops filter didn't always correctly position
813 the image on the page when printing in landscape
814 orientation.
815 - The ppdEmit() functions now support the
816 RequiresPageRegion attribute when sending InputSlot
817 and ManualFeed commands.
818 - The PPD loading code now supports standard options
819 outside of OpenUI/CloseUI as required by the PPD spec.
820 - The cupstestppd program has been upgraded to provide a
821 concise PASS/FAIL report, additional detailed
822 conformance testing, and support for gzip'd PPD files.
823 - The PPD loading code is now much more strict when
824 loading a PPD file, and tracks more format errors.
825 - The scheduler ignored child signals when gathering the
826 list of available devices, when it should have been
827 using the default signal handler.
828 - The cupsEncodeOptions() function could encode an
829 option with a NULL last string.
830 - The socket backend could report the wrong number of
831 backchannel bytes if an error occurred on the link.
832 - The cups-polld program now only sleeps after getting
833 all printers and classes. This allows for longer
834 intervals without excessive delays before classes show
835 up...
836 - Added a new httpWait() function to support waiting for
837 data for a specific number of milliseconds.
838 - httpGets() now times out after 1 second on
839 non-blocking HTTP connections.
840 - The scheduler no longer accepts rangeOfInteger values
841 that are out of order (e.g. 5-1)
842 - The sides attribute was incorrectly sent as a name
843 value; it is a keyword value.
844 - The IPP backend now detects if the destination queue
845 has gone away and reports an error.
846 - The scheduler and HTTP API now allocate their select()
847 sets to support larger numbers of clients on systems
848 that support it.
849 - The scheduler now sets the CFProcessPath environment
850 variable under MacOS X.
851 - The cupsLangDefault() function now uses the
852 CoreFoundation localization API under MacOS X.
853 - The httpSeparate() function didn't handle file URIs of
854 the form "file:///path" properly.
855 - The lpadmin command now supports a "protocol" option
856 for specifying the binary communications protocol to
857 use when printing binary PostScript data.
858 - The scheduler did not properly parse the SystemGroup
859 directive, so only the first group would be used.
860 - Revamped how strings are stored in the scheduler,
861 providing a substantial improvement in memory usage
862 for systems with large numbers of printers.
863 - The PostScript filter now supports binary PostScript
864 files and files beginning with the PJL language escape
865 sequence.
866 - The PPD API now provides additional information from
867 the PPD file.
868 - The USB backend didn't compile on Solaris Intel.
869 - The cupstestppd utility now supports the "-q" option
870 (quiet) for use in scripts, etc.
871 - Merged several weight-reducing changes into the CUPS
872 baseline donated by Apple.
873 - Added preliminary support for CDSA; patch provided by
874 Apple.
875 - Implicit classes are now created from identical
876 printer classes on the network.
877 - The lp command now supports a "-H restart" option to
878 restart previously printed jobs. This functionality
879 only works if you have enabled the PreserveJobFiles
880 option.
881 - The scheduler now supports URIs in HTTP request lines
882 to conform to the HTTP/1.1 specification.
883 - The time-at-xyz attributes were not recognized in
884 banner files if prefixed by a question mark, e.g.
885 "{?time-at-creation}".
886 - Added support for pre-filtering application/pictwps
887 files on MacOS clients before sending them to a server
888 via IPP.
889 - The scheduler now allows file:/dev/null device URIs
890 even if FileDevices is set to No.
891 - CUPS uses strerror() for hostname resolution errors,
892 when it should have used hstrerror().
893 - The USB backend no longer tries to guess the serial
894 number of a device from the USB devices file; this
895 means that printers that don't report their serial
896 numbers in the device ID string will not be
897 individually selectable.
898 - The pstops filter didn't handle page ranges properly
899 when a page contained an embedded document.
900 - Added a translation of the web interface to German.
901 - When printing using the OutputOrder=Reverse option
902 with duplexing, the output order is now truly
903 reversed; the order of sub-pages when printing N-up is
904 the same.
905 - The pstops filter did not always output the extra
906 blank page when printing a document with an odd number
907 of pages with duplexing enabled.
908 - The ippAddXYZ functions no longer allow the
909 application to add less than 1 value.
910 - Fixed a URL rewrite bug in the web interface - local
911 access was sometimes redirected away from localhost...
912 - The ppdOpen() functions could get in an infinite loop
913 if the PPD file contained a keyword or text that was
914 too large for the buffer.
915 - Added preliminary support for GNU TLS; patch provided
916 by Jeff Licquia.
917 - Now timeout IPP attribute reads after 1 second inside
918 an attribute definition.
919 - Now timeout connections that have been shutdown (due
920 to errors) after 30 seconds instead of the Timeout
921 setting (300 seconds by default). This provides
922 faster recovery from DoS attacks.
923 - A denial-of-service attack warning message was being
924 written to the log files by the scheduler for every
925 detection. This caused a DoS of its own in some
926 situations. The warning message is now written no more
927 than once per minute.
928 - Fixed the CIE colorspace support code in the image and
929 PS RIPs.
930 - The job-quota-period, job-page-limit, and job-k-limit
931 attributes were not flagged as integers, so setting
932 quotas would not work.
933 - Added an additional response check in the scheduler to
934 more quickly recover from denial-of-service attacks.
935 - The cupstestppd file was incorrectly installed in the
936 /usr/sbin directory instead of /usr/bin.
937 - The EPM list file did not include the cupstestppd
938 program or man page files.
939
940
941 CHANGES IN CUPS V1.1.18
942
943 - Fixed a bug in the Set-Job-Attributes code in the
944 scheduler that would cause it to crash or continuously
945 write a job control file.
946 - SECURITY FIX: The scheduler now provides a FileDevice
947 directive to control whether new printers can be added
948 using device URIs of the form "file:/filename". The
949 default is to not allow printers with these device
950 URIs.
951 - The scheduler did not compute the cost of filters
952 properly, nor did it choose a multi-filter solution
953 with a lower cost than a single filter solution.
954 - Now install CUPS PPD file test utility (cupstestppd)
955 to support basic conformance testing of PPD files.
956 - The scheduler now logs an error message when it sees a
957 non-conforming PPD file.
958 - Upgraded pdftops filter to Xpdf 2.01 with fixes for
959 TrueType fonts.
960 - Added a MaxClientsPerHost configuration directive to
961 provide limited protection against Denial of Service
962 attacks.
963 - SECURITY FIX: Potential underflow/overflow bug in web
964 interface.
965 - SECURITY FIX: Race condition in certificate creation.
966 - SECURITY FIX: Bad URIs in browse packets could be used
967 to exploint the web interface underflow/overflow bug.
968 - SECURITY FIX: Some types of Denial of Service attacks
969 were not handled properly, so once the attack was over
970 the scheduler did not close the connections
971 immediately on all platforms.
972 - SECURITY FIXES: Added integer overflow/underflow
973 checks for all image formats.
974 - The pstops filter didn't reset the showpage operator
975 back to its original at the end of a job; this
976 prevented the concatenation of documents (used
977 primarily for CUPS 1.2...)
978 - The cupsGetPPD() function didn't always set the
979 cupsLastError() value when an error occurred.
980 - The IPP media, output-bin, and sides attributes took
981 precedence over the corresponding PPD options, which
982 caused inconsistent behavior under MacOS X with some
983 PPD files.
984 - The cupsaddsmb utility specified the wrong number of
985 arguments to the adddriver command when adding the
986 Win9x PostScript drivers.
987 - The web interface did not always report the correct
988 error message.
989 - The scheduler did not clear the POSIX signal action
990 structure when waiting for the child to send it a
991 SIGUSR1 signal; this could cause the signal handler
992 not to be called properly, preventing the parent
993 process from returning.
994
995
996 CHANGES IN CUPS V1.1.17
997
998 - The "manual_copies" option did not work when the LPD
999 backend had to retry a print job.
1000 - The image filters did not convert GIF images properly.
1001 - The RunAsUser option was incompatible with the new
1002 daemon-mode code in 1.1.16.
1003 - Fixed a problem with the Set-Job-Attributes and
1004 PostScript job ticket code in the scheduler - the
1005 "last" attribute pointer was never updated, which
1006 could cause the scheduler to crash when applying job
1007 ticket data.
1008 - Fixed a problem in the scheduler that caused it to
1009 continue processing HTTP requests on a connection
1010 after it was shutdown.
1011 - The scheduler now allows accounts authenticated via
1012 PAM to not have a corresponding UNIX account, but
1013 group membership still requires the account name to be
1014 listed in the UNIX group file(s)...
1015 - The scheduler used a fixed-size (16k) buffer for
1016 encoding job options for filters; it now dynamically
1017 allocates and expands the buffer as needed depending
1018 on the options that are sent in a job.
1019 - The pdftops filter didn't support all of the MacOS
1020 characters for MacRoman encoded fonts.
1021 - The cupsEncodeOptions() and cupsParseOptions()
1022 functions now conform to the grammer defined by the
1023 current draft of the PAPI specification. The main
1024 difference is that option=yes and option=no are no
1025 longer treated as boolean options.
1026 - The IPP backend didn't honor the encryption settings
1027 in /etc/cups/client.conf.
1028 - Fixed a potential bug in the HTTP code which was
1029 caused by servers sending the status line and
1030 newline(s) in separate packets.
1031 - User-defined classification strings are now printed
1032 verbatim - previously the classification box would be
1033 empty.
1034 - Re-added Spanish to the list of PPD languages that
1035 CUPS supports.
1036 - CUPS API library user and temp file updates for
1037 Windows.
1038 - The image filters did not properly handle grayscale
1039 printing of Sun Raster images.
1040 - The scheduler never reset the NumJobs variable before
1041 loading the job list (previously this only happened on
1042 a full start, so the problem was never apparent...)
1043 - The HTTP and IPP read/write code didn't handle EINTR
1044 (interrupted system call) errors.
1045 - When under high load, the scheduler could abort due to
1046 the wrong errno value after a select() call. This was
1047 caused by the child signal handler.
1048 - Added new load tests to the test target to verify that
1049 cupsd can handle hundreds of simultaneous jobs without
1050 error.
1051 - The Solaris USB backend now supports the new device
1052 URI syntax.
1053 - The ppdOpen*() functions now reset the numeric locale
1054 settings while loading a PPD file.
1055 - Fixed the libtool build rules.
1056 - The manpage make rules didn't use $(MAKE) and
1057 $(MFLAGS) for the language subdirectories.
1058 - Now set the LC_TIME locale category to get the
1059 properly localized time string.
1060 - Fixed a problem in the scheduler that would cause the
1061 web interface problems when adding, modifying, or
1062 configuring a printer or class.
1063 - The backends now ignore SIGPIPE so that failed job
1064 filters will not stop a print queue.
1065 - The lpstat command did not allow for destination lists
1066 ("lpstat -v printer1,printer2")
1067 - Fixed parsing of long filter status messages in the
1068 scheduler.
1069 - Added some startup performance enhancements to the
1070 scheduler so that the printer object information is
1071 regenerated fewer times and the MIME type database is
1072 not filled with lots of empty filters for raw/direct
1073 queues.
1074 - The LPD backend now sends the job title as the print
1075 filename.
1076 - Added support for variable sizes in the EPSON dot
1077 matrix printer drivers. This allows for pages as
1078 short as 1/2" (1 row of labels) and does not do an
1079 automatic form feed.
1080 - French translation updates.
1081 - The filters did not quote the page label string when
1082 embedding it in PostScript output.
1083 - The serial backend now enumerates serial ports under
1084 MacOS X.
1085 - The pdftops filter contained font rasterizer code that
1086 wasn't being used and that depended on X11. This code
1087 has been removed.
1088
1089
1090 CHANGES IN CUPS V1.1.16
1091
1092 - The cancel and lprm commands now both display an error
1093 message and return a non-zero exit status if an
1094 attempt is made to cancel a job on a non-existent
1095 printer.
1096 - The lpoptions command incorrectly complained if a
1097 request to delete a non-existent printer was made.
1098 - If the client.conf file defines an alternate server
1099 name, the "configure printer" action in the web
1100 interface might not work.
1101 - The lpstat command now supports a "-W" option so that
1102 you can display completed jobs as well as
1103 not-completed (pending) jobs.
1104 - The lp and lpr commands did not return an error when
1105 one or more files in a set of files for printing could
1106 not be printed.
1107 - The lp, lpadmin, and lpstat commands now consistently
1108 return with a non-zero exit status when an error
1109 occurs.
1110 - The scheduler would not accept print jobs sent to a
1111 stopped remote printer.
1112 - The texttops filter incorrectly converted the page
1113 numbers in the prettyprint header to double-byte
1114 characters when printing a non-Unicode text file. This
1115 caused an extra space to appear between each digit in
1116 the page number.
1117 - The scheduler did not use a case-insensitive
1118 comparison when adding filters for a printer.
1119 - Upgraded the pdftops filter to Xpdf 1.01.
1120 - The scheduler no longer passes the page-border and
1121 number-up-layout attributes to filters when printing
1122 banner pages.
1123 - The LPD backend now uses a 30-second timeout when
1124 sending commands and control files, and a 30-second
1125 timeout when retrieving responses from an LPD server.
1126 If a timeout occurs, it retries indefinitely. This
1127 helps to make LPD printing over VPNs work more
1128 reliably.
1129 - The USB backend now supports device URIs based on the
1130 printer serial number and/or model number under Linux.
1131 This avoids the "wrong device filename" problem when
1132 using more than one USB printer.
1133 - Now just shutdown the receiving end of a client
1134 connection when sending an error that requires the
1135 server to disconnect from the client afterwards. This
1136 fixes a problem when doing remote administration with
1137 encryption enabled.
1138 - The scheduler did not send a printer-state-message
1139 attribute if the string was empty; it now always sends
1140 this attribute. This caused the printer message to be
1141 displayed for other printers in the web interface.
1142 - The LPD backend now supports a "manual_copies" option,
1143 e.g.: "lpd://server/queue?manual_copies=no", in order
1144 to handle copies for raw jobs to printers that don't
1145 implement the LPD protocol properly...
1146 - The "mirror" option was not being handled by the
1147 PostScript or image filters.
1148 - Updated the cupsaddsmb command to support the new CUPS
1149 driver for Windows NT/2k/XP.
1150 - Filter status lines longer than 1023 characters could
1151 cause the scheduler to get into an infinite loop.
1152 - The scheduler didn't reset the job state to pending
1153 when modifying an active printer.
1154 - Now limit the maximum number of recursion steps when
1155 searching for a filter for a job, in case a user
1156 defines a circular filter rule.
1157 - The PostScript filter would embed an invalid
1158 requirements comment in some cases.
1159 - Added support for embedded job tickets in PostScript
1160 files.
1161 - The PostScript filter now detects EPS files and should
1162 better handle printing EPS files.
1163 - The cancel command now ignores a trailing destination
1164 name when cancelling a specific job ID (Solaris
1165 compatibility).
1166 - The scheduler now rejects jobs with copies outside the
1167 range of 1 to MaxCopies, inclusive.
1168 - Added new MaxCopies directive to set the maximum
1169 number of copies that a user can request.
1170 - The scheduler didn't block signals while it processed
1171 others and when it forked processes.
1172 - The scheduler checked for new jobs to print when
1173 stopping a job. This caused jobs to restart before a
1174 shutdown.
1175 - Updated the CUPS startup script to better support
1176 different timezones and to support the RedHat/Mandrake
1177 init script functions, if available.
1178 - The scheduler did not properly handle backslashes in
1179 banner files; it incorrectly assumed that "\c" should
1180 always be replaced by "c", instead of only looking for
1181 "\{" and replacing it by "{".
1182 - The texttops filter didn't handle prettyprint=no.
1183 - The text and HP-GL/2 filters didn't check for other
1184 common duplex option names like cupsMarkOptions() did.
1185 - "lpoptions -x printer" no longer clears the "default
1186 printer" status of the printer.
1187 - cupsTempFd() now stops trying to create a temporary
1188 file after 1000 tries, and aborts on any error other
1189 than EEXIST. This should prevent lp/lpr hangs due to
1190 a bad or missing temporary directory.
1191 - The lpadmin command did not send the right URI to the
1192 scheduler when setting options on classes. This
1193 caused a client-error-bad-request error.
1194 - The CUPS API convenience functions would attempt to
1195 connect to the remote server name in a
1196 "printer@server" printer name instead of dealing with
1197 the default (usually local) server. Aside from
1198 causing user confusion, the remote server name might
1199 not be resolved properly, causing further problems.
1200 - "lp -q" would cause the "lp" command to segfault, as
1201 the program would try to print the option letter that
1202 caused the error using the wrong index into the
1203 command-line; bugfix from Debian.
1204 - Fixed a minor inconsistancy in the encoding of boolean
1205 attributes from printer options in
1206 cupsEncodeOptions().
1207 - Added a FilterNice directive which sets the priority
1208 of job filter processes that are run by the scheduler.
1209 - Added Solaris x86 USB printer support.
1210 - The USB backend now reports both the ulpt and unlpt
1211 devices under *BSD.
1212 - The "lpstat -o" command would truncate the
1213 "printer-jobid" string if it was longer than 21
1214 characters.
1215 - The PJL-based MIME type rules now look in the first
1216 1024 bytes instead of just the first 512 bytes to find
1217 the language mode.
1218 - The image file types are now listed explicitly in the
1219 mime.convs file so that additional image file formats
1220 do not use the standard CUPS image filters by default.
1221 - Updated the Software Programmers Manual to include
1222 all of the CUPS API functions.
1223 - ppdOpen*() no longer sorts choices for an option.
1224 - The web interface now enforces constraints in PPD
1225 files when configuring a printer.
1226 - When stopping a printer, the scheduler didn't set the
1227 printer state before stopping the current job.
1228 - The cupsaddsmb utility now lists all data files for
1229 Win9x and WinMe clients when installing that Windows
1230 driver.
1231 - Jobs submitted to a class now bounce immediately to
1232 the next available printer rather than waiting until
1233 that printer is available.
1234 - Filters and backends now also get the CLASS
1235 environment variable set when a job is printed to a
1236 printer class instead of a normal printer.
1237 - Added French translations of the web interface, CUPS
1238 Overview, Software Administrators Manual, and Software
1239 Users Manual contributed by Marian REYT-LLABRES.
1240 - Added several "hint" messages for common configuration
1241 problems that are stored in the error_log file.
1242 - httpSeparate() now unquotes %xx characters in the
1243 username:password field of a URI.
1244 - When starting the scheduler in daemon mode, the parent
1245 process now waits for the child to signal it is ready
1246 to accept connections.
1247 - Added -F option to cupsd to run cupsd in the
1248 foreground but detach from the controlling terminal
1249 and current directory.
1250 - The scheduler did not reload jobs when receiving a HUP
1251 signal; this would cause problems since the pointers
1252 into the file type database would no longer be valid
1253 for existing jobs.
1254 - The scheduler did not save the network interface list
1255 update time, thus no caching of the network data was
1256 actually provided.
1257 - Updated the SuSE PAM configuration file.
1258 - The LPD backend now supports a "reserve" option and no
1259 longer reserves a priviledged port by default.
1260 - The cupsaddsmb command now continues past printers
1261 that do not have a PPD file to export.
1262 - The lpstat command didn't treat printer names as
1263 case-insensitive.
1264 - The lpstat command now reports the printer location
1265 attribute with "lpstat -l -p".
1266 - Fixed a bug in the vsnprintf() emulation function,
1267 which was used on old versions of HP-UX, IRIX, and
1268 Solaris.
1269 - The number-up option was incorrectly being used when
1270 printing banner pages.
1271 - Added support for Greek and Slovak PPD files.
1272 - CUPS now supports printer names containing any
1273 printable character, e.g. "123-abc", "foo-bar", etc.
1274 - The null filter was not supported in mime.convs due to
1275 a bug in the filter validation code.
1276 - Changes in the default printer and printer attributes
1277 were not always reflected in the generated printcap
1278 file.
1279 - Implicit classes did not inherit the location or
1280 description from member printers.
1281 - The httpGetHostByName() function did not handle
1282 hostnames that started with a number.
1283 - Updated the filters to use the %cupsRotation comment
1284 instead of %%Orientation to auto-rotate pages, since
1285 the use of %%Orientation is inconsistent.
1286 - Added the RootCertDuration directive to control how
1287 often the root authentication certificate is updated.
1288 - Increased the size of the IPP write buffer to 32k to
1289 allow for larger attribute values and to provide more
1290 efficient output of large numbers of attributes.
1291 - The polling daemon now retries the initial connection
1292 to the remote server; this fixes a problem when the
1293 remote server is unavailable when the scheduler starts
1294 up...
1295 - The scheduler didn't validate Digest users against the
1296 system group(s), so Digest and BasicDigest
1297 authentication didn't work for administration
1298 operations.
1299 - The scheduler now passes the SHLIB_PATH environment
1300 variable to child processes (HP-UX shared libraries)
1301 - The scheduler now maps accesses from the loopback
1302 interface to "localhost".
1303 - The cups-lpd mini-daemon sent a status code byte in
1304 response to queue state commands, but those commands
1305 only return textual data.
1306
1307
1308 CHANGES IN CUPS V1.1.15-1
1309
1310 - The lpc and lprm sources didn't include the CUPS
1311 string function header, which is required on systems
1312 that don't have their own snprintf() function.
1313 - The French manpage Makefile tried to install the
1314 language subdirectories when it (obviously) didn't
1315 have to.
1316
1317
1318 CHANGES IN CUPS V1.1.15
1319
1320 - Updated the CUPS license agreement for the new MacOS
1321 license exception.
1322 - The printer-info attribute now defaults to the printer
1323 name if no value has been set.
1324 - ppdOpen() and friends now add an "Auto" InputSlot
1325 option if none is provided to automatically select the
1326 correct tray.
1327 - Updated the ppdEmit() and ppdEmitFd() functions to
1328 (re)mark the correct PageSize or PageRegion option
1329 depending on the selected ManualFeed or InputSlot
1330 options.
1331 - ppdEmitFd() didn't handle custom page sizes.
1332 - Darwin uses <pam/pam_appl.h> instead of
1333 <security/pam_appl.h>.
1334 - The jobs.cgi web interface now handles all job
1335 operations, allowing the administrator to allow "job
1336 administrators" or operators to manage jobs (but not
1337 queues) on the server.
1338 - The cupsDoFileRequest() function now checks if the
1339 filename passed into the function is a directory, and
1340 returns the IPP_NOT_POSSIBLE error if so.
1341 - New SCSI printer backend.
1342 - Cleaned up handling of locales with trailing character
1343 set definitions.
1344 - Fixed handling of invalid PPD attributes inside
1345 OpenUI/CloseUI.
1346 - Fixed a problem with SSL and the job, printer, and
1347 admin CGIs on ports other than 443.
1348 - The scheduler didn't handle AuthClass properly.
1349 - Added French translation of man pages.
1350 - Updated the text filter to support the const_cast,
1351 dynamic_cast, and static_cast keywords in ISO C++.
1352 - Now use strlcat() and strlcpy() (or emulation
1353 functions) for easier string/buffer protection.
1354 - The auto-generated printcap/printers.conf files now
1355 have a small comment header explaining where the file
1356 comes from...
1357 - The PostScript filter now supports 6, 9, and 16-up
1358 output, as well as new page-border and
1359 number-up-layout options.
1360 - The lpoptions command didn't set options properly when
1361 using the default printer.
1362 - Added ConfigFilePerm and LogFilePerm directives.
1363 - Increased maximum size of MIME types to IPP_MAX_NAME
1364 to allow for longer printer names.
1365 - No longer create remote printers when loading job
1366 history data.
1367 - The printer-make-and-model attribute wasn't set when
1368 the PPD file didn't contain a NickName attribute.
1369 - Now handle PPD files with translation strings longer
1370 than 80 bytes - they are truncated if they go over...
1371 - The scheduler didn't handle signals until after it
1372 loaded the configuration files the first time; this
1373 caused problems on some installations that would
1374 restart the scheduler as the system booted into run
1375 level 3.
1376 - Now throttle broadcasts like we do for polling.
1377 - Fixed a bug in the reading of PPD files using CR's
1378 instead of CR LF's or LF's.
1379 - The scheduler would crash if cupsd.conf contained a
1380 BrowseProtocols line with no protocols listed.
1381 - The HTML job operation templates now link back to the
1382 destination printer or class.
1383 - The serial backend now detects USB serial devices.
1384 - The LPD mini-daemon (cups-lpd) now passes the
1385 job-originating-host-name attribute to the scheduler
1386 (cupsd).
1387 - Updated the IPP backend to reconnect after downgrading
1388 from IPP/1.1 to 1.0, and when sending requests to HP
1389 JetDirect interfaces that don't support HTTP
1390 Keep-Alive like they should.
1391 - Now pass NLSPATH and DYLD_LIBRARY_PATH environment
1392 variables, if defined, to CGI and job processes.
1393 - Removed the pstoraster filter (based on GNU
1394 Ghostscript 5.50) and now provide the raster "driver"
1395 and patch file necessary to use the current GNU
1396 Ghostscript 7.05 release.
1397 - Removed unnecessary fonts and updated the Courier and
1398 Symbol fonts to the latest versions to better support
1399 non-ISOLatin1 text.
1400 - The text filter now always embeds the Courier and
1401 Symbol fonts to ensure that they contain the full set
1402 of glyphs.
1403 - The lp and lpr commands now only override the SIGINT
1404 handler if it is not being ignored (patch from Robert
1405 Ambrose for some interactive software that catches
1406 SIGINT and will gracefully cancel the print...)
1407 - The PostScript image filter (imagetops) now supports
1408 printing CMYK images using the CMYK colorspace.
1409 - The image filters now support CMYK JPEG files, and
1410 correctly handles the inverted files from Photoshop
1411 (which seems to save RGBW data, not CMYK...)
1412 - Added a "check" target to the top-level makefile to
1413 conform with GNU standards (same as "test").
1414 - The IPP code didn't always map the POSIX locale "C" to
1415 the proper IPP language code.
1416 - The cupsaddsmb program was updated to use the
1417 setdriver command instead of addprinter.
1418 - Banner pages were not handled properly for implicit
1419 classes.
1420 - When tunneling to a remote system using SSH, the
1421 printer URIs for local printers on the remote system
1422 did not reflect the correct port number.
1423 - The Allow, Deny, BrowseAllow, BrowseDeny, and
1424 BrowseAddress directives now support the network
1425 interface names "@LOCAL" and "@IF(name)" for access
1426 control and browsing based on the current interface
1427 addresses instead of fixed names or IP addresses.
1428 - The texttops filter did not properly recognize the
1429 "nowrap" (wrap=false) option.
1430 - The InstallableOptions group name in a PPD file is now
1431 translated separately (CUPS_MSG_OPTIONS_INSTALLED) so
1432 that UIs can accurately detect the presence of this
1433 group.
1434 - The scheduler no longer keeps job history data for
1435 remote printers on the client (just on the server.)
1436 - The parallel and USB backends now retry if the backend
1437 detects that the printer is not connected to the
1438 system (rather than stopping the queue...)
1439 - The network backends now retry if the backend detects
1440 that the printer is not connected to the network or is
1441 unreachable (rather than stopping the queue...)
1442 - The cupsGetDests() function no longer lists options
1443 and instances for printers that no longer exist.
1444 - The scheduler now converts the document language to
1445 the correct LANG string.
1446 - The cupsaddsmb program now supports alternative CUPS
1447 and SAMBA server names.
1448 - The PostScript filter now supports the Orientation
1449 comment and rotates the page as needed automatically.
1450 - Revamped the makefiles slightly to use automatically
1451 generated dependencies.
1452 - Build fixes for OS X.
1453 - The TIFF reading code depended on the newest version
1454 of libtiff; now conditionally compile that portion of
1455 the loader.
1456 - The PPD code now decodes all JCL options in the
1457 JCLSetup group, not just those options that start with
1458 the prefix "JCL".
1459 - The backends now read print data using the read()
1460 system call to ensure that the current page is printed
1461 while the next page is being processed.
1462 - The pdftops filter did not support shading type 3
1463 (radial fill) for the "sh" operator.
1464 - The cups-polld program now throttles the local
1465 broadcasts of polled printers and classes so that the
1466 local system is not overwhelmed with hundreds of
1467 printers and classes all at once.
1468 - Updated the serial backend to support 230,400 baud for
1469 the Linux PPC port.
1470 - The cupsGetJobs() function wouldn't report completed
1471 jobs that did not have a document-format attribute
1472 value.
1473 - The cupsEncodeOptions() function now maintains a table
1474 of known boolean and numeric options, and encodes all
1475 other options as strings.
1476 - Now add a newline before the end-of-page code in the
1477 PostScript filter; this fixes a problem with files
1478 that don't end with a newline.
1479 - The image filters looked for the "orientation" option
1480 instead of the correctly named "orientation-requested"
1481 option.
1482 - The cupsEncodeOptions() function now handles mixed
1483 integers and ranges.
1484 - New translation guide for developers to provide native
1485 language support for CUPS.
1486
1487
1488 CHANGES IN CUPS V1.1.14
1489
1490 - The ippRead() function did not verify that the
1491 attribute name length or string with language value
1492 was not larger than the read buffer.
1493 - The scheduler set the signal handlers before loading
1494 the configuration files the first time; this prevented
1495 the RunAsUser directive from blocking server reloads.
1496 - Added Swedish message catalog.
1497 - The parallel backend now recognizes the /dev/printers
1498 device directory under Linux 2.4.x.
1499 - MacOS X fixes.
1500 - The cupsaddsmb utility sent the server name after the
1501 user information when executing the rpcclient program.
1502 This caused problems with some versions of SAMBA
1503 2.2.x.
1504 - The IPP backend did not pass the requesting user name
1505 when checking on the print job status. This prevented
1506 it from waiting for the job to complete when
1507 communicating with some IPP implementations that
1508 require it.
1509
1510
1511 CHANGES IN CUPS V1.1.13
1512
1513 - The lpstat command did not report jobs submitted to
1514 regular printer classes.
1515 - The texttops filter didn't use sufficient precision
1516 when positioning text with some values of cpi and lpi.
1517 This could cause the alignment of text to stray.
1518 - cupsGetDests() didn't merge the options from the
1519 /etc/cups/lpoptions file with ~/.lpoptions - options
1520 in ~/.lpoptions overrode them completely.
1521 - Added support for KOI8-R and KOI8-U character sets,
1522 and added several Russian message catalogs.
1523 - The scheduler put the wrong timezone offset in the log
1524 files (e.g. +0500 instead of -0500 for EST...)
1525 - The scheduler did not ignore trailing whitespace in
1526 *.convs files.
1527 - The scheduler now forces all processes to exit (kill
1528 -9) when it is stopped. This prevents parallel and
1529 USB devices from running in the background after cupsd
1530 goes away.
1531 - The cupsParseOptions() function didn't skip trailing
1532 whitespace after quoted values.
1533 - More changes to support CUPS on OS/2.
1534 - Added Simplified Chinese message catalog.
1535 - Added PAM support for IRIX.
1536 - The cupsGetPPD() function didn't remove the @server
1537 portion of the printer name, and since it would
1538 connect immediately to the remote server instead of
1539 the local server, the printer would not be found.
1540 - Classification and page labels were not rotated to
1541 match the page orientation.
1542 - Now set the TCP "no delay" option on network
1543 connections to improve performance/response time.
1544 - Improved the IRIX printing tools support with patches
1545 from Andrea Suatoni.
1546 - Added a new PrintcapGUI directive to specify the GUI
1547 option panel program to use for the IRIX printing
1548 tools support.
1549 - The cupsGetDests() function did not check to see if a
1550 user-defined default printer (set via lpoptions) still
1551 existed.
1552 - The pstops filter no longer assumes that the default
1553 dictionary is writable when doing N-up processing.
1554 - The pstops filter now supports printing N-up with the
1555 page-set option.
1556 - The imagetoraster filter now supports direct printing
1557 of CMYK image data without conversion/correction.
1558 - The IPP backend now reports printer state/error
1559 conditions when possible (toner low, media empty,
1560 etc.)
1561 - The lpstat command now supports the (undocumented)
1562 IRIX -l option ("-lprintername") for a compact job
1563 listing for a printer.
1564 - The lpstat command now includes printer date/time
1565 information in the output (always Jan 01 00:00) to
1566 make third-party tools happy.
1567 - The text filter now supports non-integer cpi and lpi
1568 values.
1569 - The Margins field in the CUPS raster header was not
1570 initialized by the pstoraster filter.
1571 - Added --with-optim="flags" option to configure script.
1572 - Updated the Italian message translations.
1573 - Updated the cups.list file to install the correct
1574 files.
1575 - The pstoraster filter accessed the third element of a
1576 2 element array.
1577 - The scheduler did not setup a status pipe for polling
1578 processes, so error messages went to whatever file
1579 descriptor 2 was pointing to when they were started.
1580 - The httpMD5Final() function didn't put a colon between
1581 the password and nonce strings.
1582 - The pstops filter did not default to Binary data for
1583 "%%BeginData:".
1584 - The pstops filter did not stop processing when a line
1585 containing a CTRL-D is seen.
1586 - The scheduler no longer replaces the JobSheets values
1587 from the printers.conf and classes.conf files with the
1588 classification level, if set. This way the original
1589 banner settings are preserved when classification
1590 levels are changed or turned off.
1591 - The serial backend didn't drain the output queue, nor
1592 did it restore the original settings.
1593 - Updated the default system group under MacOS X.
1594 - If no SystemGroup was defined in cupsd.conf, the
1595 system default group was not used.
1596 - The cups-lpd mini-daemon now supports LPD clients that
1597 send multiple control files.
1598 - httpConnectEncrypt() now always uses encryption for
1599 connections on port 443, since port 443 is reserved
1600 for the "https" scheme.
1601 - Group authentication via certificates did not work
1602 from the web interface for accounts other than
1603 "root".
1604 - The serial port backend did not clear the OPOST
1605 option, which could cause problems with some printers.
1606 - The cups-lpd mini-daemon didn't lookup the client IP
1607 address properly.
1608 - The parallel backend now identifies the polled and
1609 interrupt-driven devices under *BSD.
1610 - The scheduler allowed the "always" encryption mode
1611 inside a Location, which is not valid.
1612 - The CUPS startup script now checks for the timezone
1613 information under Linux.
1614 - Now also map the sides attribute to the JCLDuplex
1615 option (if present) in PPD files.
1616 - Updated pdftops to Xpdf 0.93a.
1617 - Added support for MD5 passwords under Slackware.
1618 - Added new AuthType BasicDigest that does Basic
1619 authentication using the MD5 password file managed by
1620 the lppasswd command.
1621 - The banner page attribute substitution code now
1622 retains {name} sequences in banner files when the
1623 named attribute is undefined. Use {?name} to
1624 conditionally substitute an IPP attribute.
1625 - The scheduler now ensures that the ServerRoot
1626 directory and configuration files are owned by and
1627 writable by the User and Group in cupsd.conf.
1628 - The USB backend now lists all USB printer devices
1629 regardless of whether a printer is connected or not.
1630 This allows new USB printers to be connected without
1631 restarting cupsd.
1632 - Added some more minor performance tweeks to the IPP
1633 protocol code to reduce copying and array indexing.
1634 - The cupsaddsmb utility now uses the -c option with
1635 smbclient and rpcclient to avoid the read length limit
1636 for commands on the standard input.
1637 - Added an include file to the CRD handling code in
1638 pstoraster so that it would compile properly on 64-bit
1639 pointer platforms...
1640
1641
1642 CHANGES IN CUPS V1.1.12
1643
1644 - Added "Polish" to the list of known languages for PPD
1645 files.
1646 - Added missing directory definition to cups-config.
1647 - The CUPS-Move-Job operation did not set the
1648 destination type for the new destination.
1649 - The CUPS-Add-Printer operation did not support the
1650 allow=all or deny=none values to clear the per-user
1651 printer ACLs.
1652 - The SetPrinterAttrs() function did not handle invalid
1653 PPD files that were missing the required NickName
1654 attribute. It now looks for NickName, ModelName, and
1655 then substitutes the string "Bad PPD File" for the
1656 printer-make-and-model attribute.
1657
1658
1659 CHANGES IN CUPS V1.1.11
1660
1661 - Added support for embedded TrueType fonts in PDF
1662 files.
1663 - Added support for PostScript functions in PDF
1664 files.
1665 - Added new "cupsaddsmb" utility for exporting
1666 CUPS printer drivers to SAMBA/Windows clients.
1667 - Added preliminary support for Darwin/MacOS X.
1668 - The CUPS-Add-Printer operation no longer allows
1669 arbitrary scheme names in device URIs to be used - it
1670 now restricts the available schemes to those found in
1671 the device list (lpinfo -m).
1672 - The ippRead() and ipp_read_file() functions could not
1673 handle more than IPP_MAX_VALUES (100) values in a
1674 1setOf attribute. These functions have been updated
1675 to dynamically allocate more memory as needed, and the
1676 IPP_MAX_VALUES constant now represents the allocation
1677 increment. [this caused some versions of the
1678 GIMP-print drivers to fail since the number of media
1679 options exceeded 100...]
1680 - The scheduler could crash when BrowseShortNames
1681 was set to "No".
1682 - The scheduler did not prevent MaxClients from being
1683 set to 0, which could cause the scheduler to go in an
1684 infinite loop when accepting a request.
1685 - Made some performance optimizations in the ippRead()
1686 functions to make IPP request/response processing
1687 faster.
1688 - The accept/reject/enable/disable command did not
1689 support properly support the "-h" or default
1690 server name.
1691 - The scheduler did not save the quota configuration
1692 when the job-quota-period attribute was set to 0.
1693 - The LPDEST and PRINTER environment variables did not
1694 support printer instances.
1695 - The text filter now handles more types of boldface and
1696 underline formatting.
1697 - The cupsTempFd() function did not fail if the
1698 temporary directory did not exist; this would cause it
1699 to loop indefinitely instead of returning an error
1700 (-1).
1701 - Stopping (disabling) a printer class did not stop jobs
1702 from printing to printers in that class.
1703 - The cupsGetDests() function was sending the
1704 requested-attributes attribute as a name instead of a
1705 keyword; this caused a serious performance problem on
1706 slower systems since more information had to be
1707 transferred from server to client.
1708 - The web interfaces did not always quote < and & in
1709 things like the job title. This had the potential for
1710 browser-based security violations (on the browser's
1711 machine); bug report from SuSE.
1712 - The scheduler now treats unauthenticated usernames as
1713 case-insensitive when doing quota and allow/deny
1714 processing.
1715 - The lp command sent the "request ID is ..." message
1716 to stderr instead of stdout...
1717 - The PostScript filter (pstops) now handles EPS files,
1718 adding a showpage command to the files as needed.
1719 - The configure script checked for the <stdlib.h> header
1720 file before the JPEG libraries; since the JPEG headers
1721 can define HAVE_STDLIB_H, the configure check would
1722 cause the JPEG check to fail on some systems.
1723 - The scheduler now supports localized banner files,
1724 using the subdirectory approach, e.g. the "es"
1725 subdirectory under /usr/share/cups/banners is used for
1726 the Spanish banner files.
1727 - Updated the scheduler so it knows the correct
1728 language abbreviation to use for all supported
1729 PPD LanguageVersion values. The new code also
1730 supports country codes as well, so "English-GB"
1731 maps to the "en_GB" locale.
1732 - The cups-lpd mini-daemon did not support
1733 anonymous printing (no username specified).
1734 While the username is REQUIRED by RFC-1179,
1735 MacOS clients do not send the REQUIRED username
1736 information when printing via LPD.
1737 - Added many warning and informational messages
1738 to cups-lpd where they were missing.
1739 - Added Czech message file contributed by SuSE.
1740 - The cups-lpd mini-daemon now returns a non-zero
1741 status if an invalid destination or job ID is
1742 provided.
1743 - The scheduler did not honor the KeepAlive setting in
1744 cupsd.conf.
1745 - Increased the size of the file read/write buffers to
1746 32k.
1747 - *BSD static library creation fixes.
1748 - Use mkstemps() instead of tmpnam() in pdftops whenever
1749 possible.
1750 - Added httpGetHostByName() function as a wrapper around
1751 gethostbyname() - some implementations of this
1752 function do not support IP addresses (e.g. MacOS X.)
1753 - Added casts to all printf's of file lengths, since
1754 there is currently no standard way of formatting long
1755 long values.
1756 - The client filename field was not cleared in all
1757 instances, resulting in old form data being submitted
1758 to CGIs.
1759 - The httpConnect*() functions now try all available
1760 addresses for a host when connecting for the first
1761 time.
1762 - The pstoraster filter would "lose" all drawing
1763 commands when the PageSize was set but the printer
1764 bitmap was not reallocated. This was most noticeable
1765 with the output from StarOffice 6 beta and would
1766 result in a blank page being output...
1767 - The IPP backend was sending a PAGE comment even when
1768 printing the output from a filter (it should only send
1769 page comments when printing files directly...)
1770 - The pdftops filter didn't properly map glyph names of
1771 embedded Asian TrueType fonts.
1772 - Changed the CUPS startup script to look for a program
1773 named "cupsd", not just any program with "cupsd" in
1774 the name (this caused the apcupsd UPS monitoring
1775 daemon to be stopped/restarted...)
1776 - The CUPS-Move-Job operation did not change the
1777 internal destination name for held jobs, so moved (but
1778 held) jobs would still show up as queued on the
1779 original destination.
1780 - The cups-polld program didn't send the
1781 requested-attributes attribute in the
1782 CUPS-Get-Printers and CUPS-Get-Classes requests, which
1783 made it use more CPU and bandwidth than required.
1784 - The scheduler and CUPS API incorrectly added a
1785 job-sheets-default attribute for remote printers. This
1786 caused banner pages to be omitted from client system
1787 prints.
1788
1789
1790 CHANGES IN CUPS V1.1.10-1
1791
1792 - Minor fixes to the filter, systemv, and template
1793 makefiles to install files properly.
1794
1795
1796 CHANGES IN CUPS V1.1.10
1797
1798 - Added a driver for DYMO label printers.
1799 - Added new ClassifyOverride directive to allow users
1800 to override the classification of individual jobs.
1801 - Added new BrowseProtocols directive to control which
1802 browse protocols are used (currently CUPS and SLP).
1803 - Added SLPv2 support (thanks to Matt Peterson for
1804 contributing the initial implementation for CUPS.)
1805 - Adding a raw printer on a remote CUPS server now
1806 correctly redirects PPD file requests to the remote
1807 server.
1808 - The serial backend now limits writes to 1/10th
1809 second worth of data to avoid buffer overflows
1810 with some types of flow control.
1811 - The scheduler did not properly process PUT requests,
1812 so configuration files could not be uploaded to the
1813 server.
1814 - The scheduler did not strip trailing whitespace on
1815 lines in the configuration files.
1816 - The httpWrite() function did not transition the PUT
1817 request to the HTTP_STATUS state to get the status
1818 from the server.
1819 - The scheduler did not properly handle trailing null
1820 ("-") filters when testing a driver that sent data
1821 to the file: pseudo-backend.
1822 - The IPP backend now only sends a document-format of
1823 "application/vnd.cups-raw" when printing to another
1824 CUPS server using a local printer driver or interface
1825 script. Previously the job's document format was
1826 used, which was incorrect.
1827 - The lpadmin command didn't use the ppd-name attribute
1828 with the -m option; this prevented the use of the
1829 "raw" model from the command-line.
1830 - The pstoraster filter output draft (1-bit) 6-color
1831 output in the wrong order; this resulted in yellow
1832 being printed instead of black on Stylus Photo
1833 printers.
1834 - The pdftops filter did not have the Japanese and
1835 Chinese text support compiled into it.
1836 - The IPP and AppSocket backends did not clear the
1837 "waiting for print job to complete" status message,
1838 which caused some confusion... :)
1839 - The serial backend now opens the port in "no delay"
1840 mode to avoid DCD detection problems with some OS's.
1841
1842
1843 CHANGES IN CUPS V1.1.9-1
1844
1845 - The configure script did not substitute the
1846 correct user and group names.
1847 - The configure script did not use the full path
1848 to the install-sh script when it was used.
1849 - The pstoraster filter did not correctly support
1850 DuplexTumble mode for printers that used flip
1851 duplexing.
1852 - The cups.list.in file was missing from the
1853 distribution.
1854 - The New DeskJet series driver did not use the
1855 correct OrderDependency for the Duplex option.
1856 - Use read() instead of fread() to read piped
1857 print files in lpr/lp. This avoids a bug in the
1858 HP-UX 10.20 fread() function.
1859 - Updated the pstoraster filter to use the MIPS_FIXADE
1860 system call under IRIX to fix bus error problems on
1861 R12000 processors (Ghostscript is not 64-bit clean...)
1862 - Some Xerox PPD files (most notably the Phaser 790)
1863 have illegal whitespace in the option keyword in the
1864 OpenUI line. This caused the PageRegion option to not
1865 be recognized properly for the Phaser 790.
1866
1867
1868 CHANGES IN CUPS V1.1.9
1869
1870 - Revamped the configure script to use a modular
1871 approach for the various tests.
1872 - Added --with-openssl-* options to properly reference
1873 the OpenSSL libraries in DSOs.
1874 - Added --with-cups-user and --with-cups-group
1875 options to specify the default user and group for
1876 CUPS.
1877 - Added AIX shared library support.
1878 - Added AIX device discovery for the serial and
1879 parallel ports.
1880 - Now use install program or script to install
1881 directories, files, and symlinks.
1882 - Updated pstops filter to use strict handling of EPS
1883 files embedded in a PostScript document. The %%EOF
1884 handling in 1.1.8 caused some dvips files not to
1885 print.
1886 - Fixed yet another memory allocation bug in pstoraster
1887 that would cause it to crash. This fix also ensures
1888 that all memory allocations are done on (at least) a
1889 64-bit boundary.
1890 - Fixed Digest authentication - httpGetSubField() didn't
1891 skip the Digest keyword.
1892 - The scheduler did not properly handle Digest
1893 authentication with the new multiple-group support.
1894 - The scheduler did not allow usernames that were
1895 not in the UNIX password file to be used for Digest
1896 authentication from passwd.md5.
1897 - The scheduler could not scan PPD files that only used
1898 a carriage return (i.e. MacOS PPD files); the new code
1899 is also about 40% faster, so servers with thousands of
1900 PPD files should start much faster now.
1901 - The scheduler now stores the PPD file size and
1902 modification times in the ppds.dat file, so it can now
1903 incrementally update the PPD database from the model
1904 directory, resulting in significantly faster startup
1905 times.
1906 - The lpinfo command did not return a non-zero status
1907 code if an error occurred.
1908 - Fixed a bug in the scheduler's UpdateJob() function.
1909 Basically, all jobs shared the same status buffer, and
1910 the "buffer start" pointer could point to 1 byte
1911 before the beginning of the buffer. The new
1912 implementation uses a separate buffer for each job and
1913 eliminates the buffer start bug.
1914 - The IPP backend would send N copies of a document if
1915 the receiving device didn't support the copies
1916 attribute, even if the upstream driver already added
1917 the necessary commands to generate the copies. This
1918 was most noticeable with HP printers where N * N
1919 copies would come out instead of N.
1920 - The PostScript filter (pstops) did not properly handle
1921 duplex printing on inkjet printers that provide this
1922 option. Copies would be put on the front and back
1923 sides of the duplexed page, and the filter did not
1924 output an even number of pages.
1925 - The backends always caught SIGTERM after they
1926 connected to the printer. This prevented raw jobs
1927 from being cancelled early.
1928 - The cupsSetDests() function now removes any printers,
1929 instances, and options that are not defined by the
1930 user or server. This should prevent old system-wide
1931 options from being used in individual user accounts.
1932 - Updated the EPSON printer driver and added PPDs for
1933 the newer EPSON Stylus printers that only support the
1934 "ESC i" graphics command.
1935 - The lpadmin command didn't allow you to add remote
1936 printers to a local class.
1937 - The lpadmin command didn't allow you to set the
1938 options (quotas, etc.) for a class.
1939 - The scheduler did not load or save the
1940 job-sheets-default attribute for classes.
1941 - The scheduler did not automatically recreate remote
1942 printers that were part of a class.
1943 - It was possible for a printer class to list the same
1944 printer more than once.
1945 - The scheduler now makes a backup copy of classes.conf
1946 and printers.conf before writing the new file.
1947 - The lppasswd program incorrectly asked for a new
1948 password when deleting an existing MD5 password
1949 account.
1950 - The scheduler did not match "/printers/name.ppd"
1951 against a location of "/printers/name".
1952 - The client code did not always handle HTTP encryption
1953 upgrades properly.
1954 - The client code now caches the last Digest password so
1955 it can retry using a new resource path or nonce value,
1956 which are included in the MD5 sum sent to the server.
1957 This should eliminate unnecessary password prompts
1958 when using Digest authentication.
1959 - The lppasswd command didn't have a man page.
1960 - Updated the PJL detection rules to allow the universal
1961 escape to occur anywhere in the first 128 bytes of the
1962 file.
1963 - The cups-polld program would poll servers continuously
1964 with no delay if there was an error contacting the
1965 server.
1966 - The IPP backend would send an empty job-name or
1967 requesting-user-name attribute if the corresponding
1968 job attribute was an empty string. While this is
1969 allowed by the IPP specification, some HP JetDirect
1970 implementations return a client-error-bad-request
1971 error if an empty name attribute value is received.
1972 The new code only sends these attributes if they are
1973 not the empty string.
1974 - At least some versions of the HP JetDirect firmware
1975 do not correctly implement IPP. Added additional
1976 checks to the IPP backend to eliminate extra,
1977 unsupported attributes which should normally be
1978 ignored by a compliant IPP device.
1979 - The scheduler did not copy the complete list of
1980 supported file types into the
1981 document-format-supported attribute. This caused
1982 clients to not send the local file type (such as
1983 application/vnd.cups-raw for raw print files) and the
1984 corresponding bad output in some cases.
1985 - The scheduler did not fully copy attributes from a
1986 set-job-attributes request - string attributes were
1987 only referenced, which could cause cupsd to crash
1988 or behave irratically.
1989 - The lp command didn't send the right value for the
1990 job-hold-until attribute when "-H resume" was
1991 specified.
1992 - The IPP backend now returns as soon as a job is
1993 completed or reported as "pending-held".
1994 - Added new ImplicitAnyClasses and HideImplicitMembers
1995 directives to the cupsd.conf file to make implicit
1996 classes more usable/transparent to the user.
1997 - Clients can now (with the appropriate authentication)
1998 retrieve and update the server configuration files
1999 using HTTP GET and PUT requests.
2000 - The web interface didn't allow you to modify the
2001 location or description of the printer.
2002 - The pdftops filter now uses its own temporary file
2003 function to work with PDF files using LZW compression
2004 (which use the uncompress program or gunzip)
2005 - The SystemGroup directive now supports specification of
2006 multiple groups.
2007 - Added new Include directive to cupsd.conf, a la
2008 Apache.
2009 - Added new pseudo-driver/PPD called "raw" that can be
2010 used to create/convert a raw queue. This also allows
2011 raw queues to be created in the web interface.
2012 - The pdftops filter didn't handle image objects that
2013 used JPEG and Flate compression together.
2014 - The pstops filter counted pages wrong when using the
2015 N-up and even/odd printing options. This prevented
2016 the page-ranges option from working properly.
2017 - Added another fix to pstoraster for a bus error
2018 condition caused by a lack of parenthesis in the
2019 Ghostscript code.
2020 - Added new "natural-scaling" option which scales the
2021 natural size of the image (percent of natural image
2022 size instead of percent of page size.)
2023 - The lppasswd program is now setuid to the CUPS user
2024 instead of root.
2025 - The PPD functions did not allow for PPD files that
2026 defined the page sizes and margins before the page
2027 size options.
2028 - The mime.types file now checks for the PJL "LANGUAGE =
2029 Postscript" command for PostScript files.
2030 - The scheduler did not truncate file: output files.
2031 - The PPD file reading code did not handle options with
2032 raw quotes (") in the human-readable names.
2033 - The pdftops filter now remaps the space character when
2034 (bad) PDF files contain a .notdef glyph for the space
2035 character.
2036
2037
2038 CHANGES IN CUPS V1.1.8
2039
2040 - Updated spec file to generate separate cups-pstoraster
2041 package for pstoraster.
2042 - The spec file wasn't setting LOGDIR in the install.
2043 - The scheduler might restart a stopped printer after
2044 stopping a print job. Thanks to Florent
2045 Guiliani for finding this bug!
2046 - The init script showed run level 0 for the Red Hat
2047 chkconfig program. This is incorrect because Red Hat
2048 doesn't use run level 0 for shutdown scripts.
2049 - The IPP backend did not handle the
2050 client-error-not-found error when checking the status
2051 of the job that was sent. This caused remote queues
2052 to stop on client machines when the server had job
2053 history disabled.
2054 - Added httpConnectEncrypt() function to avoid
2055 performance penalty for setting up encrypted
2056 connections initially.
2057 - Use httpConnectEncrypt() in all client apps and in the
2058 CUPS API to ensure consistent usage of encryption
2059 throughout.
2060 - Jobs weren't queued to remote classes (fix from
2061 Richard Begg.)
2062 - AIX changes from Richard Begg.
2063 - Fixed the pstops fix for GNOME output - no longer use
2064 the page numbers in the %%Page: comment since GNOME
2065 puts a filename instead (!?@!#?!). There is still an
2066 issue with N-up printing since GNOME defines its fonts
2067 in the first page instead of the document setup section
2068 (pages must be independent according to the DSC spec)
2069 People with GNOME printing problems should consult bug
2070 #54489...
2071 - The imagetops filter produced PAGE: messages when
2072 generating PostScript for a non-PostScript printer
2073 (only affects page-label and Classification
2074 options.)
2075 - The updated pdftops filter was looking for an options
2076 file called xpdf.conf instead of pdftops.conf.
2077
2078
2079 CHANGES IN CUPS V1.1.7
2080
2081 - Configuration script changes, including new
2082 "--with-docdir=/dir" option to relocate CUPS
2083 documentation and web content according to your
2084 favorite version of the FHS.
2085 - Documentation updates for encryption, SLP, etc.
2086 - New Software Test Plan and automated test script to
2087 test CUPS prior to installation.
2088 - All scheduler configuration files are now case
2089 insensitive to match Apache.
2090 - Added support for Apache ListenBackLog, Require,
2091 Satisfy, <Limit>, <LimitExcept>, and LimitRequestSize
2092 directives.
2093 - Added support for all Apache log levels...
2094 - Added support for "double" HostNameLookups.
2095 - Added new "RunAsUser" directive to support non-root
2096 configurations on the standard (priviledged) ports.
2097 - Added support for non-root invocation of the lpd
2098 backend (does no reserve a priviledged port, which
2099 might not work with some LPD servers...)
2100 - Added new PrintcapFormat directive to control the
2101 output format of the printcap file (BSD or Solaris
2102 formats are supported at present.)
2103 - The CUPS directory service routines now handle
2104 ECONNREFUSED errors gracefully rather than shutting
2105 all browsing off.
2106 - ippErrorString() now returns the recommended error
2107 messages from the IPP/1.1 Model and Semantics
2108 document.
2109 - Fixed a minor IPP compliance issue with responses
2110 to requests without the attributes-charset or
2111 attributes-natural-language attributes.
2112 - Sun fix: need httpFlush() call for chunked IPP
2113 requests in cupsDoFileRequest().
2114 - httpConnect() now looks up "localhost" by name and
2115 by address (127.0.0.1) for users the go to the
2116 trouble of removing the required localhost entry
2117 in /etc/hosts or on their DNS server...
2118 - Added support for Linux 2.4.x devfs parallel port
2119 filenames (/dev/parallel/N).
2120 - cupsDo[File]Request() and cupsGetPPD() no longer
2121 block trying to reconnect to a crashed or inaccessable
2122 server.
2123 - Added new ppdEmitJCL() function to better handle
2124 PJL commands from PPD files.
2125 - A bug in UpdateJob() would cause the scheduler to
2126 consume 100% CPU until another request was submitted.
2127 - The cancel command did not support the "-" option to
2128 cancel all jobs on all printers.
2129 - The cancel and lprm commands did not support cancelling
2130 the next/current job in the queue.
2131 - The pdftops and pstoraster filters were using unsafe
2132 temporary file functions; while this is not a problem
2133 in normal configurations (the CUPS temporary directory
2134 is restricted), they now use the cupsTempFd() function.
2135 - The mime.types file was missing the recognition rule
2136 for Sun Raster images.
2137 - The admin CGI was passing a printer make string to
2138 ippSetCGIVars() that was being replaced in that
2139 function.
2140 - "lpoptions -l" would resave the options...
2141 - The EPSON drivers now send the "end packet mode"
2142 command when printing to USB devices.
2143 - The scheduler initialized certificates before loading
2144 the cupsd.conf file.
2145 - The scheduler used /dev/random to collect random data,
2146 which could block if insufficient entropy information
2147 had been collected by the kernel. Now use
2148 /dev/urandom.
2149 - Fixed a bug in the whitespace skipping code in
2150 httpGetSubField().
2151 - The LPD backend now supports a new "order" option:
2152 "lpd://server/queue?order=control,data" (default) and
2153 "lpd://server/queue?order=data,control".
2154 - The scheduler enforced a 30 second timeout on all
2155 clients regardless of the Timeout directive and if a
2156 CGI was currently running.
2157 - cupsParseOptions() now sets boolean options to
2158 option=true or option=false.
2159 - The "percent complete" calculations in the LPD backend
2160 could overflow on large files, causing the percentage
2161 to wrap to 0 every 40MB or so.
2162 - Fixed a memory reallocation bug in pstoraster that
2163 could cause it to crash.
2164 - The LPD backend now sanitizes the job title to avoid
2165 potential problems on remote LPD servers.
2166 - The lp command did not send the requesting-user-name
2167 attribute when altering a job.
2168 - The pstops filter did not handle PostScript files with
2169 lines longer than 8191 bytes.
2170 - The scheduler no longer uses inet_addr() to convert IP
2171 addresses in dot format (mmm.nnn.ooo.ppp) to the
2172 32-bit format, since it will not work for IPv6
2173 addresses.
2174 - New "Classification" directive to force labeling of
2175 the current classification on each page.
2176 - New "page-label" attribute to add per-page labels
2177 ("For Official Use Only", "Draft", etc.)
2178 - The scheduler now sets the HTTPS environment variable
2179 for CGI programs when a client connects using
2180 encryption.
2181 - Fixed a recursion bug in the scheduler that could
2182 cause cupsd to crash when a printer was removed.
2183 - The LPDEST and PRINTER environment variables didn't
2184 support instances.
2185 - Dropped the "file" backend from the device list that
2186 is reported, since it is only available for *testing*
2187 and should never be used in a production environment.
2188 The file: device can still be used, but it won't show
2189 up in the list of devices from lpinfo or the web
2190 interface.
2191 - Added support for /dev/lpa# parallel ports under *BSD.
2192 - Added META variables to the CGI header template to
2193 prevent caching of the results.
2194 - Fixed an unaligned memory buffer for the pstoraster
2195 clist states; this caused bus errors for some
2196 combinations of printers, drivers, and options.
2197 - Re-added black reduction for colorful colors; this
2198 helps to prevent dark colors from getting desaturated.
2199 (only used when converting RGB to CMYK)
2200 - Added two new directives - MaxJobsPerPrinter and
2201 MaxJobsPerUser - to allow an administrator to set
2202 the maximum number of pending jobs in a queue or
2203 submitted by a user.
2204 - The scheduler no longer stops a printer if it can't
2205 create the status pipe or run the filters or backend.
2206 This will allow heavily loaded servers to service
2207 clients or start print jobs as the load allows.
2208 - Fixed a bug in the Set-Job-Attributes code that could
2209 crash the scheduler (patch from Martin Zielinski)
2210 - cupsSetDests() did not quote option values with
2211 embedded spaces.
2212 - Added support for the Enable-Printer and
2213 Disable-Printer extension operations (same as
2214 CUPS-Accept-Jobs and CUPS-Reject-Jobs.)
2215 - The AppSocket and IPP backends now wait for the print
2216 job to be finished before exiting; this should prevent
2217 the loss of print jobs with older JetDirect firmware
2218 and make consecutive print jobs print faster.
2219 - The BMP loading code did not handle resolution values
2220 of 0. This is a problem with BMP image files produced
2221 by the GIMP.
2222 - The HTTP Upgrade code (upgrade to TLS encryption)
2223 bypassed the authentication checks.
2224 - The HTTP Upgrade code did not send a 426 status code
2225 to the client and end the current request. This caused
2226 a race condition between the client and server for the
2227 upgrade to TLS.
2228 - Fixed a bug in the EOF and Trailer detection code in
2229 the pstops filter.
2230 - The imagetoraster filter did not add the margins to
2231 the custom page size in the raster header.
2232 - The imagetops filter did not adjust the custom page
2233 size to the size of the printed image.
2234 - The imagetops filter did not include DSC comments
2235 which are required by some printers.
2236 - The imagetops filter did not insert newlines in
2237 Base85 encoded output, causing files to contain
2238 lines longer than 255 characters (violation of the
2239 DSC).
2240 - Added support for the DeskJet 900 series duplexer
2241 and CRET color modes in the HP driver.
2242 - Added support for PPD-defined margins in the HP
2243 driver.
2244 - Fixed the debugging output from pstoraster - the
2245 font list was not terminated by a newline.
2246 - Some versions of the HP-UX pam_unix authentication
2247 module apparently do not pass the appdata_ptr argument
2248 to the conversation function, preventing the scheduler
2249 from authenticating users using PAM under HP-UX. A
2250 workaround using a static variable has been added to
2251 address this problem.
2252 - Fixed a bug in the scheduler SortPrinters() function
2253 that could cause printers to disappear or the
2254 scheduler to crash when adding a printer.
2255 - Changed the pstops filter to not do per-page filtering
2256 if the file does not conform to at least version 3.0
2257 of the document structuring conventions. This seems
2258 to "fix" printing with broken apps.
2259 - The image filters did not handle older TIFF files that
2260 lacked the samples-per-pixel and bits-per-pixel tags.
2261 - Added new cupsGetJobs() and cupsFreeJobs() functions
2262 to manage print jobs.
2263 - cupsEncodeOptions() would encode names of 0 length and
2264 cupsAddOption() and cupsParseOptions() would add names
2265 of 0 length.
2266 - The scheduler might block waiting for status messages
2267 after starting a new print job. Thanks to Florent
2268 Guiliani for finding this bug!
2269
2270
2271 CHANGES IN CUPS V1.1.6-3
2272
2273 - The configure script put the JPEG library before the
2274 TIFF library; this caused problems in some
2275 configurations since the TIFF library also supports
2276 JPEG compression of TIFF images.
2277 - Updated the configure script and makefiles to handle
2278 admin man pages with the "1m" extension (HP-UX, IRIX,
2279 Solaris, Tru64) and in odd directories (IRIX)
2280 - The updated cupsTempFile() function did not return
2281 the filename when called with a filename buffer of
2282 NULL (previously it used a static buffer.)
2283 - FreeBSD uses /dev/unlptN, but NetBSD and OpenBSD use
2284 /dev/ulptN.
2285 - DeletePrinter() didn't remove the printer from any
2286 classes it was a member of.
2287 - DeletePrinterFromClass() didn't preserve the
2288 implicit status of a class.
2289 - DeletePrinterFromClasses() didn't remove printers
2290 from implicit classes.
2291 - StartJob() didn't send the job-sheets, job-priority,
2292 and job-hold-until attributes to remote printers.
2293 - LoadAllJobs() was looking for job-sheets-completed
2294 instead of job-media-sheets-completed. This would
2295 prevent accumulation of page data after a restart
2296 of the scheduler.
2297 - The pstops and imagetops filters now generate copies
2298 using the appropriate method for a Level 1, 2, or 3
2299 printer since some Level 2/3 printers don't support
2300 the /#copies variable anymore.
2301 - The man page for cups-lpd did not mention the "-o"
2302 option.
2303 - The IPP backend didn't handle version-not-supported
2304 errors and revert to IPP/1.0 (previously it only checked
2305 for a bad-request error)
2306 - Caldera fix: lpc now reports unimplemented commands as
2307 unimplemented, not invalid.
2308 - Caldera fix: lpq didn't recognize BSD lpq "-a" option.
2309 - Caldera fix: lpr didn't recognize BSD lpr "-1", "-2",
2310 "-3", "-4", "-q", or "-U" options.
2311 - RedHat fixes: patches to GNU Ghostscript
2312 - SuSE fix: temp file creation patch to GNU Ghostscript
2313 (pstoraster).
2314 - SuSE fix: remove cgi-bin/abort.c and cgi-bin/email.c,
2315 which are not used.
2316 - SuSE fix: missing NULL check in cgi_initialize_post().
2317 - SuSE fix: potential buffer overflows in
2318 cgi_initialize_string().
2319 - SuSE fix: potential buffer overflows in
2320 ippSetCGIVars()
2321 - SuSE fix: more NULL checks in ppdOpen(); also make
2322 sure that all memory is freed on error to avoid memory
2323 leaks.
2324 - SuSE fix: Exit from child if setgid() or setuid()
2325 fails.
2326 - SuSE fix: Added setgroups() calls after setgid() and
2327 setuid() calls.
2328 - SuSE fix: potential buffer overflows in httpEncode64()
2329 calls.
2330 - SuSE fix: potential buffer overflows in httpSeparate()
2331 - SuSE fix: potential buffer overflows in ippWrite() for
2332 bad input.
2333 - SuSE fix: potential nul skip in ppd_decode() for
2334 missing hex digits.
2335
2336
2337 CHANGES IN CUPS V1.1.6-2
2338
2339 - Added changes to support NetBSD startup scripts.
2340 - Added separate compiler options for pstoraster
2341 (Ghostscript) to avoid compiler-induced errors
2342 from Ghostscript's twisted code.
2343 - The mime.types file contained syntax errors.
2344 - Updated the *BSD USB device filenames to use
2345 the /dev/unlptN files so that the USB device
2346 is not reset prior to printing (causes print
2347 corruption on many printers)
2348 - Added new cupsTempFd() function to avoid serious
2349 security bug in glibc fopen() function. The glibc
2350 fopen() function unlinks a file before creating it,
2351 which opens up possible symlink attacks.
2352 - Now reject 0-length names in add-printer and add-class
2353 requests.
2354 - Fix for pstoraster when ZLIB is not available.
2355 - cupsGetPPD() didn't reconnect when a HTTP connection
2356 was lost.
2357 - SuSE fix: httpConnect() didn't check that the
2358 value from gethostbyname() was a valid IPv4 address.
2359 - SuSE fix: httpConnect() didn't allow file descriptor 0
2360 to be used for a socket.
2361 - SuSE fix: ippRead() didn't confirm that all values in
2362 a set were numeric or string types.
2363 - SuSE fix: lppasswd race condition fixes.
2364 - SuSE fix: directive names could overflow buffer when
2365 reading *.conf files.
2366 - SuSE fix: HEAD requests for PPD files did not use the
2367 same logic as GET requests.
2368 - SuSE fix: possible buffer overflow when adding
2369 /index.html to requested directory name.
2370 - SuSE fix: possible buffer overflow when converting
2371 IPP attributes to string options for filters.
2372 - SuSE fix: creating file: device output with mode 0666
2373 instead of mode 0600.
2374 - SuSE fix: creating job info files with mode 0640
2375 instead of 0600.
2376 - SuSE fix: don't rely on snprintf() for including
2377 system name in log filenames.
2378 - SuSE fix: add bounds checking when copying quoted
2379 and hex strings.
2380
2381
2382 CHANGES IN CUPS V1.1.6-1
2383
2384 - Added configure check for getting the correct
2385 strftime() format string; %c is not Y2k safe,
2386 and %KC and NULL are not universally supported.
2387
2388
2389 CHANGES IN CUPS V1.1.6
2390
2391 - Fixed another possible DoS attack in httpGets()
2392 - Added check for "LANGUAGE = PCL" and "LANGUAGE =
2393 POSTSCRIPT" in mime.types.
2394 - Resolution options were not being passed into the
2395 filter programs properly.
2396 - The default compiler options for GCC no longer include
2397 "-g3", which apparently is deprecated in newer
2398 versions of GCC.
2399 - CheckJobs() could cause cupsd to crash if a job is
2400 cancelled in StartJob().
2401 - The printers.conf and classes.conf files are now
2402 written with restricted permissions.
2403 - The round-robin algorithm used by FindAvailablePrinter()
2404 had problems; fixes contributed by Joel Fredrikson.
2405 - If LoadAllJobs() is unable to determine the file type
2406 of a print job, assume "application/vnd.cups-raw".
2407 - The web interface now provides a job_printer_name
2408 value for any corresponding job_printer_uri value.
2409 - The cups-lpd mini-daemon now logs the client address
2410 and hostname as well as all commands and errors in the
2411 syslog file.
2412 - The IPP backend now detects the supported file formats
2413 and only specifies the document format if it is
2414 supported. This makes IPP printing to network print
2415 servers and cards more reliable without affecting the
2416 capabilities of CUPS servers.
2417 - The time_at_xyz attributes are now converted to human-
2418 readable dates and times for the web interfaces.
2419 - The HP and EPSON sample drivers now correctly catch
2420 signals and eject the current page when a job is
2421 cancelled.
2422 - Fixed bug in CGI code - did not ignore control
2423 characters (e.g. newlines) in form data. This caused
2424 sporatic web interface problems.
2425 - The file type logging code in the scheduler referenced
2426 the optional document-format attribute; the new code
2427 uses the resolved MIME type instead.
2428 - The client.conf parsing code now removes trailing
2429 whitespace.
2430 - The MaxJobs directive was being treated as a boolean
2431 instead of an integer.
2432 - The scheduler would not timeout remote printers if
2433 BrowseInterval was set to 0.
2434 - The lpadmin command now supports setting of options
2435 and user-level access control.
2436 - Added "-E" option to all printing commands to force
2437 encryption.
2438 - The client code did not consume the response to the
2439 OPTIONS request when switching to secure mode.
2440 - The scheduler did not output a Content-Length field
2441 when responding to an OPTIONS request.
2442 - Added documentation on using cups-lpd with xinetd
2443 to the man page.
2444 - The socket backend now starts retries at 5 seconds and
2445 increases the interval to 30 seconds. This should
2446 provide faster printing when multiple jobs/files are
2447 queued for a printer.
2448 - The filters and backends no longer buffer output to
2449 stderr. This should provide much more accurate status
2450 reporting.
2451
2452
2453 CHANGES IN CUPS V1.1.5-2
2454
2455 - Fixed configure check for OpenSSL to work with RSA
2456 code.
2457 - Added configure check for <sys/ioctl.h>, and use this
2458 check in backend/serial.c.
2459 - Updated configure script handling of data,
2460 configuration, and state directories to use datadir,
2461 sysconfdir, and localstatedir variables.
2462 - NetBSD uses different serial port filenames than
2463 FreeBSD and OpenBSD.
2464 - The pdftops filter didn't need some X-specific files.
2465 - The scheduler makefile doesn't do a chown anymore when
2466 installing (cupsd did this automatically on startup
2467 anyways)
2468
2469
2470 CHANGES IN CUPS V1.1.5-1
2471
2472 - There was a typo in the top-level Makefile
2473 - The top-level Makefile did not install an init script
2474 for run level 5.
2475 - The configure script did not add the "crypto" library
2476 when checking for the OpenSSL library.
2477 - The OKIDATA PPD files were missing.
2478 - The config.h.in file defined the wrong version number.
2479 - The serial backend did not define "funky_hex" under *BSD.
2480 - Updated the Visual C++ project files and some of the
2481 CUPS API sources to compile under Windows again.
2482
2483
2484 CHANGES IN CUPS V1.1.5
2485
2486 - Security updates - new default configuration does
2487 not broadcast printer information and only allows
2488 access from the local system.
2489 - EXPERIMENTAL encryption support - CUPS now optionally
2490 supports TLS/SSL encryption via the OpenSSL library.
2491 - Documentation updates.
2492 - Makefile/configure script updates.
2493 - The RPM spec file didn't work out-of-the-box under
2494 RedHat or Mandrake.
2495 - Minor code cleanup to remove extraneous compiler
2496 warnings.
2497 - cupsTempFile() was using %p for the temporary
2498 filename; this should have been %08x (just 8 digit
2499 hex)
2500 - Deleting a printer with active print jobs would still
2501 crash the server.
2502 - ippWrite() and ipp_write_file() didn't send the
2503 correct value length for name-with-language and
2504 text-with-language attributes.
2505 - Updated IPP code to support copied strings (that
2506 should not be freed); this provides slightly more
2507 efficient IPP server performance.
2508 - Updated PDF filter to Xpdf 0.91.
2509 - httpGets() could go into an infinite loop if a line
2510 longer than the input buffer size was sent by a
2511 client. This could be used in a Denial-of-Service
2512 attack.
2513 - The lpstat and CUPS API functions now request only the
2514 data required when getting the list of printer or
2515 class information. This should improve performance
2516 with large numbers of printers on slower machines.
2517 - The scheduler was always enforcing the FilterLimit,
2518 even if FilterLimit was set to 0.
2519 - Updated the Linux USB backend to support Mandrake's
2520 /dev/usb/usblp# filenames.
2521 - The PRINTER and LPDEST environment variables did not
2522 override the lpoptions default printer.
2523 - The PPD read functions incorrectly included trailing
2524 characters (usually whitespace) after quoted string
2525 attributes.
2526 - The multiple-document-handling attribute handling code
2527 did not check for the correct value for collated
2528 copies (separate-documents-uncollated-copies).
2529 - The EPSON driver did not work with OKIDATA printers in
2530 EPSON emulation mode (needed change-emulation command)
2531 - The HP-GL/2 filter did not scale the plot properly in
2532 scale mode 2.
2533 - Added PPD files for 9-pin and 24-pin OKIDATA printers.
2534 - The httpSeparate() function didn't handle passwords
2535 that started with a number.
2536 - ippDelete() could free the character set string
2537 multiple times in name-with-language and
2538 text-with-language attributes.
2539 - The scheduler would access freed memory right after
2540 freeing it (for debug messages); these parts of the
2541 code have been reordered to avoid this situation
2542 which was causing sporatic errors and crashes.
2543 - The ppdClose() function didn't free all of the strings
2544 in the ppd_file_t structure.
2545 - The LoadAllJobs() function in the scheduler did not
2546 close the spool directory.
2547 - Changed all sprintf's that use string formats to
2548 snprintf's, even if the destination buffer is
2549 larger than the source string(s); this protects
2550 against buffer overflows caused outside of CUPS...
2551 - Changed all strcpy's to strncpy's between local and
2552 global variables, even if the destination buffer is
2553 larger than the source string; this protects
2554 against buffer overflows caused outside of CUPS...
2555 - The CUPS certificate functions didn't use the
2556 CUPS_SERVERROOT environment variable when set.
2557 - The directory services code was copying instead of
2558 comparing the remote printer info, resulting in
2559 unnecessary updates of the printer attributes for
2560 remote printers.
2561 - Added new mime.types rules to allow automatic raw
2562 printing of PCL and ESC/P files; PJL headers are
2563 parsed to differentiate between PostScript and
2564 PCL job files. This should eliminate a lot of
2565 the reports of SAMBA printing problems due to
2566 the missing "-oraw" or "-l" options.
2567 - The mimeLoadType() function didn't handle the
2568 3-argument contains() function.
2569 - The LoadPPDs() function in the scheduler didn't
2570 properly set the alloc_ppds variable or handle a PPD
2571 database containing 0 printers.
2572 - The scheduler FindAvailablePrinter() function didn't
2573 use the same queuing logic as the CheckJobs()
2574 function. This caused classes to stall if a remote
2575 printer was always busy.
2576 - Jobs are now assigned to printers in a class
2577 round-robin style. This should prevent the first
2578 server in the class from bearing the brunt of the
2579 jobs.
2580 - The scheduler's LoadAllJobs() function didn't always
2581 restore remote printers for queued jobs on startup.
2582 - The serial backend didn't support the higher baud
2583 rates with the old termios interface. It now supports
2584 57600 and 115200 baud.
2585 - The serial backend now supports different types of
2586 flow control; previously it ignored the flow=XYZ
2587 option in the device URI.
2588 - The serial backend now supports DTR/DSR flow control,
2589 which is popular on dot-matrix printers (access with
2590 "flow=dtrdsr" in the device URI)
2591 - Added new job-originating-host-name attribute for
2592 jobs. The new attribute provides the hostname or
2593 IP address of the machine that submitted the job.
2594 - The set-job-attributes code no longer allows read-only
2595 job attributes to be changed.
2596 - Expanded the click area for the navigation bar in the
2597 web interface.
2598 - Updated the lp and cancel commands to support all of
2599 the Solaris print options (some are simply ignored
2600 since they do not map)
2601 - Updated the scheduler to limit the number of file
2602 descriptors to the maximum select() set size. This
2603 was causing problems on Solaris systems where the
2604 max FD count was increased beyond 1024.
2605 - The scheduler's LoadDevices() function was getting
2606 interrupted by the SIGCHLD signal handler; now ignore
2607 child signals while loading devices.
2608 - Added quota and allow/deny user support for printers
2609 and classes.
2610 - Removed black/CMY adjustment code from the PS and
2611 image file RIPs; it was interfering with some CUPS
2612 driver dithering code.
2613 - The lpc program stopped listing the queue statuses
2614 after the first active printer.
2615 - The cups-lpd program used an output format that the
2616 Solaris printing system did not understand.
2617 - Updated the lpq program to use the Solaris format
2618 except under Tru64 UNIX.
2619 - Some DEC PPD files incorrectly use "Off" for the null
2620 value in UI constraints. Added "Off" to the list of
2621 accepted null values.
2622 - Changed the *BSD define constants to __*BSD__ in all
2623 of the backends.
2624 - Added support for "lpstat printername", which is an
2625 undocumented feature in Solaris.
2626 - The HP-GL/2 filter now only sets the plot size if it
2627 is set in the plot file.
2628 - The lpmove command wasn't sending the requesting
2629 user name, causing it to always fail.
2630 - Updated the cupsTempFile() code to use GetTempPath()
2631 under Windows.
2632 - The cups-lpd mini-daemon didn't limit the number of
2633 data files accepted, didn't use cupsTempFile(),
2634 didn't handle control file job information in any
2635 order, and didn't free job options after printing
2636 a file.
2637 - The scheduler copy_banner() function did not
2638 explicitly set the owner and permissions of the banner
2639 files, which could prevent the banner pages from
2640 printing on some systems.
2641 - The lpstat program wasn't listing remote classes.
2642 - The scheduler did not verify that the printer-uri
2643 attribute was specified in all requests that required
2644 it.
2645
2646
2647 CHANGES IN CUPS v1.1.4
2648
2649 - Makefile and configure script fixes.
2650 - **** Changed the default Printcap setting **** to
2651 /etc/printcap. There are just too many people asking
2652 why application XYZ doesn't see their printers!
2653 - The web admin interface now displays an error if it
2654 can't get the list of printer drivers from cupsd.
2655 - The IPP backend was putting the copies option before
2656 the other job options were set. This caused the IPP
2657 request to contain attribute groups in the wrong
2658 order, which prevented remote printing.
2659 - Added checks in scheduler to free memory used for
2660 IPP requests and language information when closing
2661 a client connection.
2662 - Fixed the duplex option in the HP LaserJet driver. It
2663 should now work with all LaserJet printers (and
2664 compatibles)
2665 - The add-printer web interface didn't initialize the
2666 "old info" data pointer, which caused random crashes
2667 on many OS's.
2668 - Fixed many page sizes defined in the Level 1
2669 compatibility file "gs_statd.ps" to match reality.
2670 - Fixed another bug in the setpagedevice "code" in
2671 Ghostscript. It should now accept all standard
2672 Adobe attributes on all platforms.
2673 - Fixed pstoraster so that it reallocates memory for
2674 color depth changes as well as size/resolution
2675 changes. This removes an ordering constraint on
2676 the color, page size, and resolution options in
2677 PPD files.
2678 - The IPP backend didn't use the job's character set
2679 when the destination printer supported it. This
2680 caused problems when printing text files to other
2681 CUPS servers.
2682 - Updated the logic used to determine when to rebuild
2683 the PPD file database. The scheduler now checks the
2684 dates and the number of PPD files (was just checking
2685 the dates.)
2686 - Updated the ippSetCGIVars() function (used by the
2687 web interfaces) to only filter valid string values.
2688 - The PostScript filter was scaling 2-up pages
2689 incorrectly. This caused the edges of some pages to
2690 be clipped.
2691
2692
2693 CHANGES IN CUPS v1.1.3
2694
2695 - Makefile fixes.
2696 - RPM spec file changes.
2697 - Documentation updates.
2698 - Enabled pstoraster debug messages for everything
2699 (only logged when LogLevel set to "debug"...)
2700 - Changed the Input/OutputAttributes fix in
2701 pstoraster so that it works on all platforms.
2702 - The HP-GL/2 filter didn't set the right green
2703 color value in encoded polylines or text.
2704 - Updated the "fitplot" code to handle plot sizes
2705 specified as "PSwidth,length" and "PSlength,width".
2706 - Updated the Linux parallel and USB backends to open
2707 the device files prior to looking in /proc for
2708 autoprobe info. This makes sure that loadable device
2709 driver modules are in fact loaded...
2710 - Added new FilterLimit directive to limit the number
2711 of processing jobs/filters on a system.
2712 - set-job-attributes didn't change the job-state to
2713 held/pending when the job-hold-until attribute was
2714 specified.
2715 - set-job-attributes didn't save the new job attributes.
2716 - Now change the "requesting-user-name" attribute in
2717 requests from remote systems to "remroot" when an
2718 unauthenticated "root" user is sent. This can be
2719 changed using the new RemoteRoot directive in
2720 cupsd.conf.
2721 - The cancel-job, hold-job, release-job, and restart-job
2722 operations didn't log the authenticated username.
2723 - The cups-lpd mini-daemon now checks for a
2724 document-format option before forcing raw mode with
2725 filter mode 'l'.
2726 - The cups-lpd mini-daemon now supports "-o" options
2727 on the command-line (passed by inetd) to set global
2728 defaults for all print queues.
2729 - The pstops filter assumed that a file with a Trailer
2730 comment would also have an EOF comment.
2731 - Added new cupsSetPasswordCB(), cupsSetServer(),
2732 cupsSetUser(), and ippSetPort() functions to better
2733 support client applications (especially GUIs...)
2734 - The CUPS-add-class and CUPS-add-printer operations
2735 didn't reset the printer-name attribute on remote
2736 print queues that had to be renamed when a local
2737 printer was defined with the same name.
2738 - The lpoptions command now supports a "-r" option to
2739 remove options for a printer or instance.
2740 - The lpadmin and admin.cgi programs no longer allow
2741 class and printer names to begin with a number; this
2742 caused the command-line utilities to become confused.
2743 - The Linux USB backend now looks for both the parallel
2744 and usblp driver names in the device list.
2745 - Added a new FontPath directive to cupsd.conf, and also
2746 a "--with-fontpath" option for the configure script to
2747 specify alternate font paths for pstoraster.
2748 - The CUPS-move-job operation didn't update the
2749 job-printer-uri attribute.
2750 - The scheduler only looked up printers and classes by
2751 name in IPP requests, instead of using the full URI.
2752 This caused problems with KUPS and friends with
2753 remote printers.
2754 - The scheduler now handles better localization of
2755 hostnames (e.g. server is host.foo.com, remote is
2756 host.subfoo.foo.com, localized is not host.subfoo...)
2757 - The scheduler logging functions now use a common
2758 log file checking/rotation function (courtesy of
2759 Crutcher Dunnavant at Red Hat)
2760 - The scheduler could accept more client connections
2761 than it allocated for if more than one Port or Listen
2762 line was present in cupsd.conf.
2763 - Other minor scheduler performance tweeks.
2764 - The lpq and lprm commands didn't support the default
2765 printer set using lpoptions.
2766 - The lpoptions command now supports a "-l" option to
2767 list the printer-specific options and their current
2768 settings.
2769 - The web printer and class lists now show a link to the
2770 default printer or class at the top of the page.
2771 - The text filter now supports pretty printing of shell
2772 and perl scripts as well as C/C++ source files.
2773 - The top and bottom margins were reversed for landscape
2774 text printing.
2775 - The lpq and lprm commands didn't understand printer
2776 instances.
2777 - The scheduler only selected on the first 100 file
2778 descriptors instead of the maximum file descriptor
2779 limit.
2780 - The scheduler client, listener, and mainline functions
2781 now share code to disable and enable monitoring for
2782 new client connections.
2783 - The imagetoraster filter didn't support all of the
2784 required pagedevice parameters.
2785 - The serial backend now checks for 100 serial ports
2786 under Linux.
2787 - The scheduler used sscanf() to pull out the remote
2788 printer location, description, and make/model strings,
2789 but if any of these options was empty then sscanf()
2790 would stop processing.
2791 - Added "debug2" log level to provide a little less
2792 verbose debugging information at the "debug" level.
2793 - The scheduler would crash if you stopped a printer
2794 that was currently printing a job.
2795 - The scheduler incorrectly allowed jobs in the cancelled,
2796 aborted, or completed state to be cancelled.
2797 - The image filters did not load TIFF images properly
2798 for bottom-to-top and right-to-left orientations.
2799 - Added new cupsEncodeOptions() function to encode
2800 CUPS options as IPP job attributes.
2801 - The IPP backend, LPD mini-daemon, client commands,
2802 and CUPS API did not properly encode multiple
2803 option values separated by commas.
2804 - Added new scheduler malloc logging in debug mode
2805 (provides summary of total arena size, allocated,
2806 and free bytes once a minute)
2807 - The EPM-based distributions didn't install the
2808 correct symlinks for a few man pages.
2809 - Fixed a memory leak in the scheduler - wasn't
2810 freeing old filters when deleting or renaming
2811 printers.
2812 - The scheduler now queries the primary IP address
2813 for the name of the server and maps any incoming
2814 requests from that address to the server name.
2815 This fixes web admin mapping problems from
2816 server.domain.com to localhost.
2817 - The web printer modify interface now remembers
2818 the previous device and driver settings (except
2819 for serial ports.)
2820 - The job-k-octets attribute is now stored as part of
2821 the job attributes; this preserves the information
2822 after a job is completed when job file history is
2823 turned off.
2824 - Dropped option sub-group parsing code for the moment,
2825 since many Xerox PPD files abuse this feature in PPD
2826 files and don't follow the hierarchy rules.
2827 - Added new wrapper code around options so that duplex
2828 options for some HP printers don't prevent prints.
2829 - Added support for Digital UNIX/Tru64 UNIX/OSF/1 format
2830 for "lpstat -v" output.
2831 - Now show the URI for remote printers instead of
2832 /dev/null in "lpstat -v" output.
2833 - Creating classes and adding printers to a class with
2834 the lpadmin command didn't work.
2835 - The banner pages and test page should now format
2836 correctly in both portrait and landscape orientations.
2837 - Updated banner page substitution so that { can appear
2838 by itself without quoting.
2839
2840
2841 CHANGES IN CUPS v1.1.2
2842
2843 - Makefile/configure fixes
2844 - RPM spec file and EPM list file fixes
2845 - The cupsTempFile() function now uses a different
2846 algorithm for generating temp files and "reserves"
2847 them to avoid possible security exploitation.
2848 - Now use /dev/random (if available) to seed the random
2849 number generator for certificates.
2850 - The /var/spool/cups and /var/spool/cups/tmp directories
2851 were incorrectly owned by root; they are now owned by
2852 the filter user, typically "lp".
2853 - The scheduler now resets the permissions on the spool
2854 and temp directories as needed to match the filter
2855 user.
2856 - Now expose ppdCollect() as an externally callable
2857 function.
2858 - The image filters now support filtering from the
2859 standard input.
2860 - The imagetoraster filter now collects all printer
2861 options and job patch files and applies them to the
2862 page header as needed.
2863 - Added format and banner options to LPD backend.
2864 - The send-document operation didn't start a job
2865 immediately when last-document was true.
2866 - The set-job-attributes operation didn't correctly
2867 replace the current job-hold-until value.
2868 - Removed the option wrapper code from ppdEmit() and
2869 friends since it caused problems with Ghostscript
2870 and many PS printers.
2871 - Was setting TZ environment variable twice for job
2872 filters.
2873 - Added syslog logging in cups-lpd to aide in
2874 debugging problems.
2875 - The HP-UX parallel port backend did not list the
2876 available parallel ports on some systems (printf
2877 calling problem...)
2878 - The lp and lpr commands overrode user options if
2879 -d/-P were specified after -o.
2880 - The scheduler would crash with a */* filter.
2881 - Added support for a "default" filter for unknown file
2882 types. The example provided in the mime.types and
2883 mime.convs file prints unknown files as if "-oraw" was
2884 specified for the job. This functionality is disabled
2885 by default.
2886 - The "compatibility" mode fix for older backends did not
2887 work for smbspool. Added a workaround for it.
2888 - The HP-GL/2 filter didn't perform the right pen scaling
2889 with some files and the "fitplot" option.
2890 - New Software Performance Specification document that
2891 describes the memory, disk, and CPU usage of all the
2892 CUPS software.
2893
2894
2895 CHANGES IN CUPS v1.1.1
2896
2897 - The pstoraster Makefile still referenced one of the
2898 old PDF filter files.
2899 - The filter Makefile used INSTALL_DATA instead of
2900 INSTALL_LIB to install the CUPS image library.
2901 - The administration CGI didn't work properly with
2902 network devices.
2903 - The BrowseACL variable was not updated after the
2904 cupsd.conf file was loaded.
2905 - The lpd mini-daemon didn't support printer instances.
2906 - Now use a default umask of 077 for child processes.
2907 - Now put temp files in /var/spool/cups/tmp for child
2908 processes and the root user, unless TMPDIR or TempDir
2909 is defined otherwise.
2910 - cupsGetPPD() no longer uses easy-to-guess filenames.
2911 - The CUPS-Delete-Class and CUPS-Delete-Printer
2912 operations now save classes.conf file as needed.
2913 - The lppasswd command wouldn't add a user.
2914 - The ppdOpen() function could cause a segfault if a
2915 0-length PPD file was read.
2916 - The image filters were not handling images with
2917 different X and Y resolutions properly.
2918 - The imagetoraster filter defaulted to RGB output
2919 instead of black output like pstoraster.
2920 - The pstops filter didn't handle binary data properly.
2921 - The pstops filter didn't handle copies properly for
2922 PS files lacking DSC comments.
2923 - The pstops filter now appends %%EOF to the end of
2924 documents if they don't have it.
2925 - The cupsGetPPD() function didn't work with remote
2926 printers lacking the @server in the name.
2927 - The configure script didn't work right when only
2928 --prefix was specified.
2929 - The ppdEmit() code now wraps all printer commands so
2930 that buggy PostScript printers will still print a file
2931 after receiving an option that isn't available.
2932 - Fixed the DeskJet margin bug, and disabled 600dpi
2933 color mode until it can be fixed.
2934 - The cupsAddDest() function didn't sort instances
2935 correctly in all cases.
2936 - The time-at-xyz attributes now expand to the date and
2937 time in banner files.
2938
2939
2940 CHANGES IN CUPS v1.1
2941
2942 - Documentation updates.
2943 - Configuration script updates.
2944 - Didn't map charset and language value strings to lowercase
2945 and _ to - as required by SLP and IPP.
2946 - ppdLoadXYZ() didn't add the list of available fonts to the
2947 ppd_file_t structure.
2948 - The text filter common code was freeing the PPD file data
2949 before it was used.
2950 - The text filter now embeds missing fonts.
2951 - The CGI interface now maps local access to the server to
2952 the localhost address.
2953 - The HP-GL/2 filter didn't use the specified (or default)
2954 color ranges, resulting in strange colors.
2955 - The HP-GL/2 filter didn't default to no input window, which
2956 caused unnecessary clipping of plots.
2957 - Integrated Xpdf's pdftops filter into CUPS, which is a
2958 lightweight and reliable replacement for Ghostscript's
2959 PDF support.
2960 - Removed all PDF support from Ghostscript.
2961 - Updated HP driver to set top margin; this seems to fix
2962 the offset problem seen on HP DeskJet printers.
2963 - Fixed dependencies on the ZLIB and JPEG libraries in
2964 pstoraster.
2965 - The lpr command wasn't using the lpoptions defined by
2966 the user.
2967 - The lpr command would segfault if the CUPS server was
2968 not running.
2969 - The top-level makefile was not installing the CUPS
2970 initialization script. It now does so if it sees there
2971 is an init.d directory in /sbin, /etc/rc.d, or /etc.
2972 - "lpstat -v all" didn't work.
2973 - pstoraster would crash on some platforms doing the
2974 setpagedevice operator.
2975 - The web administration interface now allows you to set
2976 the default banner pages.
2977 - Images can now be positioned on the page using the new
2978 "position" option.
2979 - The AccessLog, ErrorLog, and PageLog directives now
2980 support "%s" to insert the server name.
2981 - Added a new BrowseShortNames directive to allow for
2982 short remote printer names ("printer" instead of
2983 "printer@server") when possible.
2984 - The scheduler could crash if given an invalid PPD file
2985 with no PageSize attributes.
2986 - Updated the serial, parallel, and usb backends to do
2987 multiple writes and ignore ioctl() errors as needed;
2988 this should fix problems with serial printing on old
2989 serial drivers and with the UltraSPARC parallel port
2990 driver under Solaris 2.7.
2991 - Now propagate LD_LIBRARY_PATH to child processes from
2992 cupsd.
2993 - New DataDir directive for installing in alternate
2994 locations.
2995 - New CUPS_SERVERROOT and CUPS_DATADIR environment
2996 variables to specify installation directories as
2997 needed.
2998 - Queued remote jobs recreate remote printers as needed
2999 when the scheduler is started.
3000 - Deleting a printer also purges all jobs on that
3001 printer.
3002 - Old job and control files that don't belong to a
3003 printer are automatically deleted.
3004 - Wasn't updating time-at-processing and
3005 time-at-completed attributes in job.
3006 - Didn't send required multiple-operation-time-out
3007 attribute in response to a get-printer-attributes
3008 request.
3009 - cups-lpd now supports options set with lpoptions.
3010 - The job-hold-until attribute is now provided with all
3011 jobs. For jobs that are not currently held the value
3012 is "no-hold".
3013 - The scheduler was not sending "unknown" values in IPP
3014 responses.
3015 - The lpoptions command now accumulates options from
3016 previous runs rather than replacing all options for a
3017 printer.
3018 - The IPP backend now switches to IPP/1.0 if a 1.1
3019 request fails.
3020 - The lpadmin and admin.cgi programs now validate new
3021 printer and class names.
3022 - The access_log file now includes the number of IPP bytes
3023 received in a POST request.

3026 CHANGES IN CUPS v1.1b5
3027
3028 - Documentation updates.
3029 - The pstoraster filter didn't compile without the JPEG library.
3030 - The cupsd server didn't support the HTTP OPTIONS request
3031 method.
3032 - Dropped the "CLOSE" method supported by the cupsd server.
3033 (not defined in HTTP specification)
3034 - Makefile/configure script fixes.
3035 - Missing the job-restart template.
3036 - Added IPP test suite for testing.
3037 - Missing IPP documentation from binary distributions.
3038 - Fixed multiple-document handling code when last-document
3039 not specified.
3040 - Added more checks to IPP requests to prevent bad requests
3041 from getting through.
3042 - Not all of the Ghostscript error output was being sent to
3043 stderr.
3044 - The PostScript filter now added PJL commands to set the
3045 job name and display string, if supported.
3046 - The scheduler would crash if the browse socket could not
3047 be bound. Now disables browsing if port 631 (reserved for
3048 IPP) is being used by a misbehaving daemon.
3049 - The USB backend now looks for the older Linux 2.2.x USB
3050 printer device filenames as well as the newer ones.
3051 - The IPP backend now uses the UTF-8 charset exclusively,
3052 since apparently only CUPS handles more than US-ASCII and
3053 UTF-8...
3054 - Wasn't quoting ( in PostScript banners...
3055 - Send-document requests with no document-format attribute
3056 could cause cupsd to crash.
3057 - Old jobs in the spool directory might cause cupsd to
3058 crash.
3059 - CUPS now supports all of the recommended job-hold-until
3060 keywords as well as name values of the form "HH:MM" and
3061 "HH:MM:SS".
3062 - Added placeholder pointer for TLS encryption to the HTTP
3063 connection structure.
3064 - Fixed the "fast poll" bug reported by DISA - the
3065 status pipe wasn't being closed for multi-file jobs.
3066 - Revamped put_params code in pstoraster to fix bitmap
3067 allocation bug with FrameMaker output.
3068 - Ripped out filename, etc. code from pstoraster as it
3069 is a potential security hole.
3070 - Added support for RIP_CACHE environment variable in the
3071 new pstoraster.
3072 - Fixed USB device filenames for Linux; now support new
3073 pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
3074 (/dev/usblp#)
3075 - Fixed accept-jobs crash with classes.
3076 - Didn't include dot-matrix EPSON drivers in previous
3077 release.
3078
3079
3080 CHANGES IN CUPS v1.1b4
3081
3082 - Documentation updates.
3083 - Many makefile and configuration script fixes (should
3084 now compile better under *BSD.)
3085 - The MediaPosition attribute was being mishandled by
3086 GhostScript, causing the RIP to fail whenever a paper
3087 tray was selected.
3088 - The scheduler now logs the final line of log information
3089 from a filter, even if it doesn't end with a newline; this
3090 primarily affects GhostScript error output.
3091 - The scheduler was saving implicit classes, so after a few
3092 restarts you'll end up with AnyPrinter, AnyAnyPrinter, etc.
3093 - The JPEG autodetection didn't work with some JPEG files that
3094 came from digital cameras (JPEG but not JFIF); the new
3095 magic types should work with all images that the JPEG library
3096 can handle.
3097 - Fixed a bug in the new contains() MIME type rule that could
3098 cause cupsd to crash.
3099 - Switched to using strtol() in the MIME type code so that you
3100 can use hex, octal, or decimal constants as desired in the
3101 mime.types file.
3102 - Banner files are now treated as templates, allowing any type
3103 of file to be used as a banner.
3104 - Added a 30-second timeout to backend device reports so that a
3105 hung backend will not prevent the scheduler from starting.
3106 - Backends are once again terminated when jobs are stopped; the
3107 CUPS-supplied backends will stay alive until the downstream
3108 filters have had a chance to clear out old page data.
3109 - The charset lookup in the CUPS localization support was wrong
3110 (iso8859-x instead of iso-8859-x)
3111 - Changed the "cpNNNN" code page files to "windows-NNNN" to match
3112 the IANA registrations.
3113 - New PostScript banner pages.
3114 - Added Windows BMP and Alias PIX image file support to the image
3115 filter.
3116 - The PNG reading coded didn't free all of its buffers.
3117 - Added Digest authentication support to the client and server
3118 code.
3119 - Added Solaris options to System V commands.
3120 - Now support the output-bin job template attribute.
3121 - Now log the job-billing attribute in the page_log file, and
3122 keep track of the total number of pages in the
3123 job-media-sheets-completed attribute.
3124 - The penwidth option is now in micrometers to support more
3125 accurate width specification.
3126 - The image filters now support interlaced and transparent PNG
3127 files.
3128 - Didn't handle Keep-Alive for HTTP/1.0 clients.
3129 - The BrowsePoll support didn't handle when BrowseInterval
3130 was set to 0 (now uses 30 seconds if BrowseInterval is 0)
3131 - The DeskJet driver now supports 600 DPI color for printers
3132 that support it.
3133 - New lpinfo and lpmove commands.
3134 - The lpq command now supports the Digital UNIX output format.
3135 - The LPD mini-daemon now supports all required LPD operations.
3136 - Implemented timeouts for multi-file documents.
3137 - New cupsPrintFiles() function in the CUPS API library to
3138 print multiple files using create-job and send-document
3139 requests (1 job ID for multiple files)
3140 - The lp command now sends multiple files as a single job,
3141 matching the behavior of the System V command.
3142 - The "cancel -a" command now purges job history files.
3143
3144
3145 CHANGES IN CUPS v1.1b3
3146
3147 - Documentation updates.
3148 - The startup script redirected stderr before stdout,
3149 which caused problems with some versions of Bourne
3150 shell and Bash.
3151 - Fixed a bug in the scheduler's PPD language reading
3152 code.
3153 - Fixed a bug in the scheduler's check for the
3154 manufacturer in the PPD.
3155 - The pstoraster filter didn't allow some input and
3156 output attributes to be set.
3157 - Added banner page support.
3158 - Added missing PAM configuration file.
3159 - Configuration script fixes for Linux and *BSD.
3160 - The log file code was using the wrong sign for the
3161 timezone offset.
3162 - The default printcap file is now empty (no printcap
3163 file is generated).
3164 - The scheduler did not start jobs destined for remote
3165 printers when they became available.
3166 - The scheduler now sends jobs to remote printers
3167 immediately. (when sending jobs to a class, the remote
3168 printer is only used when it becomes available)
3169 - The scheduler now supports printing of banner pages
3170 via the job-sheets attribute (banner files go in
3171 /usr/share/cups/banners)
3172 - The cupsd process now forks itself into the background
3173 (override with -f)
3174 - Added several *BSD enhancements.
3175 - Added UNSUPPORTED libtool option to configuration
3176 script to allow the use of libtool. Note that this is
3177 UNSUPPORTED by us, but added by request of the *BSD
3178 folks.
3179 - The parallel, serial, and usb backends now retry the
3180 opening of their ports. This allows multiple print
3181 queues to be associated with a single physical port,
3182 and will allow CUPS to support several types of
3183 parallel port auto-switches in the near future.
3184 - Set-Job-Attributes now supports adding, changing, and
3185 deleting job template attributes, and no longer allows
3186 job-printer-uri to be set (see CUPS-Move-Job)
3187 - Added CUPS-Move-Job operation to support moving of jobs.
3188 - The CGI template functionality now supports multiple
3189 languages (still only have templates for English)
3190 - The CUPS-Get-Printers and CUPS-Get-Classes operations
3191 now support filtering as defined in the IDD.
3192 - The Get-Jobs, CUPS-Get-Printers, and CUPS-Get-Classes
3193 operations no longer limit themselves to 1000 jobs,
3194 printers, or classes (believe it or not, this is
3195 needed for some sites)
3196 - The web interfaces now support language-specific
3197 templates.
3198 - The web admin interface now supports class management.
3199 - The web admin interface now shows a list of
3200 manufacturers before selecting the PPD/driver for a
3201 specific printer.
3202 - The web admin interface now supports configuration of
3203 the default printer options in the PPD file.
3204 - The web interface now uses printer/class
3205 authentication for the test page instead of admin
3206 authentication.
3207 - Updated the RPM spec file for the current release.
3208 - Updated language support for Windows code pages.
3209 - 8-bit character set files can now use multiple fonts
3210 (needed for Arabic, Greek, Hebrew, etc.)
3211 - Added basic right-to-left text support in the text
3212 filter.
3213 - The POSIX locale now uses ISO-8859-1 instead of
3214 US-ASCII.
3215 - Fixed PDF printing problems.
3216 - Fixed PostScript RIP page device dictionary elements
3217 that weren't getting passed in cups_get_params().
3218 - Added a new "contains" rule for the magic file typing.
3219 - The "printable" rule now accepts characters from 128 to 255
3220 (needed for Microsoft character sets)
3221 - Added support for ~/.cupsrc as well as /etc/cups/client.conf
3222 so that the default server can be configured on a per-user
3223 basis without environment variables.
3224 - Added LPD mini-daemon to support incoming LPD jobs.
3225
3226
3227 CHANGES IN CUPS v1.1b2
3228
3229 - Documentation updates.
3230 - The lp command didn't always load the user-defined
3231 destinations, preventing it from seeing the default
3232 printer.
3233 - Many configure script and makefile fixes.
3234 - The Microsoft code page files were missing from the
3235 distribution.
3236 - Added a workaround for the HP IPP client (which is sending
3237 an invalid printer-uri in requests)
3238 - Fixed the encoding of text-with-language and name-with-language
3239 to match the IPP spec.
3240 - Added support for unknown value tags in the IPP routines
3241 (previously they would be ignored)
3242 - Integrated GNU GhostScript 5.50 into the pstoraster filter.
3243 - Client hostname resolution was broken on little-endian
3244 machines.
3245 - Now look at client.conf file for client's default server
3246 and printer.
3247 - The cupsServer() function did not close the client.conf file
3248 if it contained a ServerName directive.
3249 - Added BrowseAllow, BrowseDeny, BrowseOrder, BrowsePoll, and
3250 BrowseRelay directives.
3251 - BrowseInterval 0 disables advertising of local printers, but
3252 still receives information on remote printers.
3253 - New browse polling daemon (for polling servers on different
3254 networks)
3255 - New PPD cache file for faster startup times with large numbers
3256 of PPD files.
3257 - The Host: field was incorrectly required for HTTP/1.0 clients.
3258 - New set-job-attributes operation now supported.
3259 - The mime_load_types() and mime_load_convs() functions did not
3260 close their input files.
3261
3262
3263 CHANGES IN CUPS v1.1b1
3264
3265 - NEW web-based administration interface.
3266 - NEW EPSON printer drivers.
3267 - NEW user-defined printers and options.
3268 - NEW persistent jobs and job history
3269 - NEW IPP/1.1 support
3270 - NEW template-based web interfaces.
3271 - NEW CUPS-get-devices and CUPS-get-ppds operations.
3272 - NEW support for create-job and send-file operations.
3273 - NEW certificate-based authentication for local
3274 administration.
3275 - NEW USB backend.
3276 - The lpr command now produces human-readable error messages.

3280 - The IPP backend did not always detect when the "raw" option
3281 was being used.
3282 - The "lpstat -p" command would stop after the first active
3283 printer.
3284 - The "lpstat -v" command would stop before the first remote
3285 printer.
