b696f4e3 4CHANGES IN CUPS V1.1.19rc2
5
2abcdcaa 6 - The path for the "ln" command was hardcoded in
7 Makedefs.in instead of being checked at configure time
8 (STR #28).
c4885a3a 9 - Banner pages containing unescaped { characters would
10 not work.
c8a55d2c 11 - The printer-state-time collection attribute was
12 encoded as an enumeration instead of an integer.
13 - The printer-is-accepting-jobs collection attribute was
14 was not added to the collection value.
15 - The printer-state-sequence-number collection attribute
16 was not added to the collection value.
d8e1f369 17 - Fixed typo and const mismatch in IPP backend.
18 - Updated the man pages for the new configuration
19 directives.
20 - Updated the SAM for MacOS 10.2, the CUPS drivers for
21 windows, the available LPD backend options, and the
22 new configuration directives.
de8a4f54 23 - The imagetops filter didn't position images properly
24 on the page (STR #18)
f2cdaedc 25 - The configure script didn't add CPPFLAGS to the
26 compiler options or LDFLAGS to the DSO options (STR
27 #13)
b696f4e3 28 - The scheduler would try to write a debug log message
29 when starting a job that contained a NULL string.
30 Since not all versions of snprintf() support NULL
f2cdaedc 31 string pointers this caused some problems (STR #20)
b696f4e3 32 - The testipp program now supports reading of IPP
33 message files such as those used for the job history
34 in /var/spool/cups.
35
36
fc7f6f69 37CHANGES IN CUPS V1.1.19rc1
6e3d4276 38
265fb4a4 39 - Added CUPS support files for Java, Perl, and PHP
40 (located in the "scripting" subdirectory...)
53510eae 41 - The scheduler now supports fast-reloads of the
42 cupsd.conf file when it is updated via HTTP.
43 - The scheduler always changed the ownership of log
44 files; it now only does so if they are not in the /dev
45 directory (i.e. don't want to change the ownership and
46 permissions of /dev/null...)
b4f2ed46 47 - Added libpaper support (patch from Jeff Licquia)
4fc54d8c 48 - Added a new istring() rule for MIME types files that
49 does a case-insensitive comparison of strings.
1e6bd2df 50 - The cups-lpd mini-daemon now sends jobs to the default
51 queue when an empty queue name (or "lp" and there is
52 no "lp" queue) is sent.
e532393d 53 - The scheduler now supports fax queues identified by a
54 "*cupsFax: True" attribute in the PPD file. When a job
53510eae 55 can't be sent, it is held for 5 minutes by default
56 while other jobs are attempted. The FaxRetryLimit and
57 FaxRetryInterval directives control the number of
58 retries and the time between retries.
0e4f2c25 59 - The scheduler now preserves the default options of PPD
60 files when modifying/upgrading an existing PPD file.
61 When installing a new printer, the scheduler sets the
62 default media size to Letter or A4 as appropriate for
63 your locale.
5073e3f8 64 - The scheduler no longer limits the number of
65 BrowseAddress, BrowsePoll, BrowseRelay, Listen, Port,
66 SSLListen, and SSLPort directives to 10.
d59a189c 67 - The scheduler now supports print files that have been
68 compressed using gzip.
4e43f59e 69 - The scheduler used the stdio functions to read any job
70 ticket information in a PostScript print job. Since
71 some platforms limit the number of stdio files to 256,
72 job ticket information was ignored when the server had
73 a large number of clients connected to the system.
8f4595eb 74 - Filters and backends may now report the total number
75 of pages ("PAGE: total NNN") to the scheduler.
55737cf0 76 - The LPD backend now supports timeout and
77 sanitize_title options (default to 300 and yes,
78 respectively) and has some additional changes to
79 reduce the chances of multiple copies being printed
80 when only one copy was requested.
b5111a23 81 - Fixed a polygon drawing bug in the HP-GL/2 filter.
ded143b8 82 - Added a robots.txt file to the standard install to
83 prevent search engines from indexing the CUPS server.
62bcac22 84 - Added support for STATE: messages
85 (printer-state-reasons), printer-state-history, and
86 printer-state-time to the scheduler.
598aeabc 87 - When using RunAsUser, the scheduler would initially
88 start any previously queued (pending) jobs with
89 RunAsUser disabled - all backends would be running as
90 root.
4d4fb342 91 - If a backend failed for a printer, CUPS would
92 incorrectly requeue the job for printing again.
c3719c59 93 - Added support for IPP collections and files.
3721af07 94 - Added experimental support for generic CGI scripts and
95 programs, Java, Perl, PHP, and Python to the
96 scheduler. See the file "CGI.txt" for more
97 information.
d40085f1 98 - The CUPS API now supports HTTP cookies and the Expect:
99 field.
dd9e85de 100 - The cancel command now correctly supports the "-u
101 user" option to cancel all jobs for the named user.
102 - The Purge-Jobs operation now supports the my-jobs
103 boolean attribute and a new purge-jobs boolean
104 attribute to control whether job history data is
105 purged from the scheduler; the default is false for
106 my-jobs and true for purge-jobs to match the original
107 implementation.
b9e3e9a0 108 - The scheduler would not timeout printers when only
109 using SLP browsing.
a5ba1d82 110 - If the scheduler was unable to execute a filter, it
111 would try to restart the job indefinitely until the
112 filter could be executed.
a9bc43ad 113 - When writing BSD printcap files, the scheduler now
114 includes the rm and rp attributes, allowing the file
115 to be exported to LPD clients. [Patch from Dominic
116 Kubla]
3f2fa036 117 - The scheduler optimization to reference IPP attribute
118 data instead of performing a full copy caused problems
119 when the referenced data was deleted before it was
120 sent. It now only references attributes that change
121 only when the scheduler is restarted. The change also
122 reduced the memory footprint of a printer object to
123 2k.
124 - The scheduler now holds signals while logging messages
125 to avoid potential deadlock issues when handling
126 signals on Solaris 8.
b27fa031 127 - The lpadmin command now allows printer access control
128 by group name as well as user name.
7057d744 129 - "lpoptions -l" got in an infinite loop if no default
130 printer was available.
131 - The scheduler now logs the job-originating-host-name
132 attribute in the page_log file, and uses "-" for any
133 empty fields (patch from Dominik Kubla).
a0db7254 134 - The pdftops filter now scales PDF pages within the
135 printable area of the page.
b43f5fd7 136 - The pstops filter didn't include the page-label and
137 classification boxes when printing EPS or non-
138 conformant PS files.
209d6c49 139 - The imagetops filter didn't always correctly position
140 the image on the page when printing in landscape
141 orientation.
b3291c5a 142 - The ppdEmit() functions now support the
143 RequiresPageRegion attribute when sending InputSlot
144 and ManualFeed commands.
145 - The PPD loading code now supports standard options
146 outside of OpenUI/CloseUI as required by the PPD spec.
43cd52be 147 - The cupstestppd program has been upgraded to provide a
148 concise PASS/FAIL report, additional detailed
149 conformance testing, and support for gzip'd PPD files.
150 - The PPD loading code is now much more strict when
151 loading a PPD file, and tracks more format errors.
5a0aab69 152 - The scheduler ignored child signals when gathering the
153 list of available devices, when it should have been
154 using the default signal handler.
dc249e0d 155 - The cupsEncodeOptions() function could encode an
156 option with a NULL last string.
8b7032be 157 - The socket backend could report the wrong number of
158 backchannel bytes if an error occurred on the link.
33073884 159 - The cups-polld program now only sleeps after getting
160 all printers and classes. This allows for longer
161 intervals without excessive delays before classes show
162 up...
2e32fcdb 163 - Added a new httpWait() function to support waiting for
164 data for a specific number of milliseconds.
165 - httpGets() now times out after 1 second on
166 non-blocking HTTP connections.
bce0c833 167 - The scheduler no longer accepts rangeOfInteger values
168 that are out of order (e.g. 5-1)
169 - The sides attribute was incorrectly sent as a name
170 value; it is a keyword value.
67474245 171 - The IPP backend now detects if the destination queue
172 has gone away and reports an error.
2e32fcdb 173 - The scheduler and HTTP API now allocate their select()
174 sets to support larger numbers of clients on systems
175 that support it.
cc6d5b1e 176 - The scheduler now sets the CFProcessPath environment
177 variable under MacOS X.
178 - The cupsLangDefault() function now uses the
179 CoreFoundation localization API under MacOS X.
f353d925 180 - The httpSeparate() function didn't handle file URIs of
181 the form "file:///path" properly.
b2d75006 182 - The lpadmin command now supports a "protocol" option
183 for specifying the binary communications protocol to
184 use when printing binary PostScript data.
9c4b5e2e 185 - The scheduler did not properly parse the SystemGroup
186 directive, so only the first group would be used.
36992080 187 - Revamped how strings are stored in the scheduler,
188 providing a substantial improvement in memory usage
189 for systems with large numbers of printers.
610e4a98 190 - The PostScript filter now supports binary PostScript
2ddb40fe 191 files and files beginning with the PJL language escape
192 sequence.
49d1718a 193 - The PPD API now provides additional information from
194 the PPD file.
6a35dc4e 195 - The USB backend didn't compile on Solaris Intel.
98c2aef5 196 - The cupstestppd utility now supports the "-q" option
197 (quiet) for use in scripts, etc.
6db7190f 198 - Merged several weight-reducing changes into the CUPS
199 baseline donated by Apple.
dcfcaeac 200 - Added preliminary support for CDSA; patch provided by
201 Apple.
8bd0441f 202 - Implicit classes are now created from identical
203 printer classes on the network.
faa0f7b5 204 - The lp command now supports a "-H restart" option to
205 restart previously printed jobs. This functionality
206 only works if you have enabled the PreserveJobFiles
207 option.
208 - The scheduler now supports URIs in HTTP request lines
209 to conform to the HTTP/1.1 specification.
cb114623 210 - The time-at-xyz attributes were not recognized in
211 banner files if prefixed by a question mark, e.g.
212 "{?time-at-creation}".
a684a3b0 213 - Added support for pre-filtering application/pictwps
214 files on MacOS clients before sending them to a server
215 via IPP.
edd85093 216 - The scheduler now allows file:/dev/null device URIs
217 even if FileDevices is set to No.
7e3ba0af 218 - CUPS uses strerror() for hostname resolution errors,
219 when it should have used hstrerror().
273e40d6 220 - The USB backend no longer tries to guess the serial
221 number of a device from the USB devices file; this
222 means that printers that don't report their serial
223 numbers in the device ID string will not be
224 individually selectable.
d0598693 225 - The pstops filter didn't handle page ranges properly
226 when a page contained an embedded document.
cb114623 227 - Added a translation of the web interface to German.
96eae06b 228 - When printing using the OutputOrder=Reverse option
229 with duplexing, the output order is now truly
230 reversed; the order of sub-pages when printing N-up is
231 the same.
232 - The pstops filter did not always output the extra
233 blank page when printing a document with an odd number
234 of pages with duplexing enabled.
2d850885 235 - The ippAddXYZ functions no longer allow the
236 application to add less than 1 value.
5b28477f 237 - Fixed a URL rewrite bug in the web interface - local
238 access was sometimes redirected away from localhost...
256f3670 239 - The ppdOpen() functions could get in an infinite loop
240 if the PPD file contained a keyword or text that was
241 too large for the buffer.
bcf61448 242 - Added preliminary support for GNU TLS; patch provided
243 by Jeff Licquia.
aea6601a 244 - Now timeout IPP attribute reads after 1 second inside
245 an attribute definition.
de218675 246 - Now timeout connections that have been shutdown (due
247 to errors) after 30 seconds instead of the Timeout
248 setting (300 seconds by default). This provides
249 faster recovery from DoS attacks.
f0ad8cdc 250 - A denial-of-service attack warning message was being
251 written to the log files by the scheduler for every
252 detection. This caused a DoS of its own in some
253 situations. The warning message is now written no more
254 than once per minute.
67fa1315 255 - Fixed the CIE colorspace support code in the image and
256 PS RIPs.
320115a7 257 - The job-quota-period, job-page-limit, and job-k-limit
258 attributes were not flagged as integers, so setting
259 quotas would not work.
6e3d4276 260 - Added an additional response check in the scheduler to
261 more quickly recover from denial-of-service attacks.
262 - The cupstestppd file was incorrectly installed in the
263 /usr/sbin directory instead of /usr/bin.
264 - The EPM list file did not include the cupstestppd
265 program or man page files.
266
267
759f5023 268CHANGES IN CUPS V1.1.18
269
e38a7cef 270 - Fixed a bug in the Set-Job-Attributes code in the
271 scheduler that would cause it to crash or continuously
272 write a job control file.
f63a430f 273 - SECURITY FIX: The scheduler now provides a FileDevice
274 directive to control whether new printers can be added
275 using device URIs of the form "file:/filename". The
276 default is to not allow printers with these device
277 URIs.
767ae392 278 - The scheduler did not compute the cost of filters
279 properly, nor did it choose a multi-filter solution
280 with a lower cost than a single filter solution.
00528abb 281 - Now install CUPS PPD file test utility (cupstestppd)
282 to support basic conformance testing of PPD files.
283 - The scheduler now logs an error message when it sees a
284 non-conforming PPD file.
ae65da6c 285 - Upgraded pdftops filter to Xpdf 2.01 with fixes for
286 TrueType fonts.
1060c9b6 287 - Added a MaxClientsPerHost configuration directive to
288 provide limited protection against Denial of Service
289 attacks.
901b295d 290 - SECURITY FIX: Potential underflow/overflow bug in web
291 interface.
292 - SECURITY FIX: Race condition in certificate creation.
293 - SECURITY FIX: Bad URIs in browse packets could be used
294 to exploint the web interface underflow/overflow bug.
901b295d 295 - SECURITY FIX: Some types of Denial of Service attacks
296 were not handled properly, so once the attack was over
297 the scheduler did not close the connections
298 immediately on all platforms.
099f4d77 299 - SECURITY FIXES: Added integer overflow/underflow
300 checks for all image formats.
9c1ee2b9 301 - The pstops filter didn't reset the showpage operator
302 back to its original at the end of a job; this
303 prevented the concatenation of documents (used
304 primarily for CUPS 1.2...)
0e66dba3 305 - The cupsGetPPD() function didn't always set the
306 cupsLastError() value when an error occurred.
daeeb91c 307 - The IPP media, output-bin, and sides attributes took
308 precedence over the corresponding PPD options, which
309 caused inconsistent behavior under MacOS X with some
310 PPD files.
dcc2e394 311 - The cupsaddsmb utility specified the wrong number of
312 arguments to the adddriver command when adding the
313 Win9x PostScript drivers.
dd44d54e 314 - The web interface did not always report the correct
315 error message.
759f5023 316 - The scheduler did not clear the POSIX signal action
317 structure when waiting for the child to send it a
318 SIGUSR1 signal; this could cause the signal handler
319 not to be called properly, preventing the parent
320 process from returning.
321
322
3cc7bca4 323CHANGES IN CUPS V1.1.17
324
5c826e17 325 - The "manual_copies" option did not work when the LPD
326 backend had to retry a print job.
3c892427 327 - The image filters did not convert GIF images properly.
2d21c1ef 328 - The RunAsUser option was incompatible with the new
329 daemon-mode code in 1.1.16.
2d5e06dd 330 - Fixed a problem with the Set-Job-Attributes and
331 PostScript job ticket code in the scheduler - the
332 "last" attribute pointer was never updated, which
333 could cause the scheduler to crash when applying job
334 ticket data.
335 - Fixed a problem in the scheduler that caused it to
336 continue processing HTTP requests on a connection
337 after it was shutdown.
3d6f3b2b 338 - The scheduler now allows accounts authenticated via
339 PAM to not have a corresponding UNIX account, but
340 group membership still requires the account name to be
341 listed in the UNIX group file(s)...
673d1710 342 - The scheduler used a fixed-size (16k) buffer for
343 encoding job options for filters; it now dynamically
344 allocates and expands the buffer as needed depending
345 on the options that are sent in a job.
8ee2dc56 346 - The pdftops filter didn't support all of the MacOS
347 characters for MacRoman encoded fonts.
a7cc258b 348 - The cupsEncodeOptions() and cupsParseOptions()
349 functions now conform to the grammer defined by the
350 current draft of the PAPI specification. The main
351 difference is that option=yes and option=no are no
352 longer treated as boolean options.
7914a6a1 353 - The IPP backend didn't honor the encryption settings
354 in /etc/cups/client.conf.
dfac1292 355 - Fixed a potential bug in the HTTP code which was
356 caused by servers sending the status line and
357 newline(s) in separate packets.
13f5eff6 358 - User-defined classification strings are now printed
359 verbatim - previously the classification box would be
360 empty.
78143282 361 - Re-added Spanish to the list of PPD languages that
362 CUPS supports.
e0578e6e 363 - CUPS API library user and temp file updates for
364 Windows.
f33d1239 365 - The image filters did not properly handle grayscale
366 printing of Sun Raster images.
bf9e2a45 367 - The scheduler never reset the NumJobs variable before
368 loading the job list (previously this only happened on
369 a full start, so the problem was never apparent...)
bdbaa675 370 - The HTTP and IPP read/write code didn't handle EINTR
371 (interrupted system call) errors.
372 - When under high load, the scheduler could abort due to
373 the wrong errno value after a select() call. This was
374 caused by the child signal handler.
375 - Added new load tests to the test target to verify that
376 cupsd can handle hundreds of simultaneous jobs without
377 error.
e1e31a38 378 - The Solaris USB backend now supports the new device
379 URI syntax.
7a1c86c5 380 - The ppdOpen*() functions now reset the numeric locale
381 settings while loading a PPD file.
b2fdde8d 382 - Fixed the libtool build rules.
383 - The manpage make rules didn't use $(MAKE) and
384 $(MFLAGS) for the language subdirectories.
d0e4469d 385 - Now set the LC_TIME locale category to get the
386 properly localized time string.
549d1888 387 - Fixed a problem in the scheduler that would cause the
388 web interface problems when adding, modifying, or
389 configuring a printer or class.
98904cd6 390 - The backends now ignore SIGPIPE so that failed job
391 filters will not stop a print queue.
d47f8ebe 392 - The lpstat command did not allow for destination lists
393 ("lpstat -v printer1,printer2")
394 - Fixed parsing of long filter status messages in the
395 scheduler.
396 - Added some startup performance enhancements to the
397 scheduler so that the printer object information is
398 regenerated fewer times and the MIME type database is
399 not filled with lots of empty filters for raw/direct
400 queues.
854d3bb2 401 - The LPD backend now sends the job title as the print
402 filename.
137d4d44 403 - Added support for variable sizes in the EPSON dot
404 matrix printer drivers. This allows for pages as
405 short as 1/2" (1 row of labels) and does not do an
406 automatic form feed.
407 - French translation updates.
e639fb32 408 - The filters did not quote the page label string when
409 embedding it in PostScript output.
3cc7bca4 410 - The serial backend now enumerates serial ports under
411 MacOS X.
412 - The pdftops filter contained font rasterizer code that
413 wasn't being used and that depended on X11. This code
414 has been removed.
415
416
06415a96 417CHANGES IN CUPS V1.1.16
418
727e6d14 419 - The cancel and lprm commands now both display an error
420 message and return a non-zero exit status if an
421 attempt is made to cancel a job on a non-existent
422 printer.
423 - The lpoptions command incorrectly complained if a
424 request to delete a non-existent printer was made.
807a1ef5 425 - If the client.conf file defines an alternate server
426 name, the "configure printer" action in the web
427 interface might not work.
7cc9aebd 428 - The lpstat command now supports a "-W" option so that
429 you can display completed jobs as well as
430 not-completed (pending) jobs.
a1ca1702 431 - The lp and lpr commands did not return an error when
432 one or more files in a set of files for printing could
433 not be printed.
3b8ff70f 434 - The lp, lpadmin, and lpstat commands now consistently
435 return with a non-zero exit status when an error
436 occurs.
db628f45 437 - The scheduler would not accept print jobs sent to a
438 stopped remote printer.
da1bfd3d 439 - The texttops filter incorrectly converted the page
440 numbers in the prettyprint header to double-byte
441 characters when printing a non-Unicode text file. This
442 caused an extra space to appear between each digit in
443 the page number.
da312e94 444 - The scheduler did not use a case-insensitive
445 comparison when adding filters for a printer.
be8c3862 446 - Upgraded the pdftops filter to Xpdf 1.01.
801766ac 447 - The scheduler no longer passes the page-border and
448 number-up-layout attributes to filters when printing
449 banner pages.
25037b2b 450 - The LPD backend now uses a 30-second timeout when
451 sending commands and control files, and a 30-second
452 timeout when retrieving responses from an LPD server.
1aef57ed 453 If a timeout occurs, it retries indefinitely. This
25037b2b 454 helps to make LPD printing over VPNs work more
455 reliably.
a9219725 456 - The USB backend now supports device URIs based on the
457 printer serial number and/or model number under Linux.
458 This avoids the "wrong device filename" problem when
459 using more than one USB printer.
c3c5af5e 460 - Now just shutdown the receiving end of a client
461 connection when sending an error that requires the
462 server to disconnect from the client afterwards. This
463 fixes a problem when doing remote administration with
464 encryption enabled.
b05809b0 465 - The scheduler did not send a printer-state-message
466 attribute if the string was empty; it now always sends
467 this attribute. This caused the printer message to be
468 displayed for other printers in the web interface.
04e01993 469 - The LPD backend now supports a "manual_copies" option,
470 e.g.: "lpd://server/queue?manual_copies=no", in order
471 to handle copies for raw jobs to printers that don't
472 implement the LPD protocol properly...
a05e4307 473 - The "mirror" option was not being handled by the
474 PostScript or image filters.
f7696015 475 - Updated the cupsaddsmb command to support the new CUPS
476 driver for Windows NT/2k/XP.
de659667 477 - Filter status lines longer than 1023 characters could
478 cause the scheduler to get into an infinite loop.
aa25b9e1 479 - The scheduler didn't reset the job state to pending
480 when modifying an active printer.
6ed689f8 481 - Now limit the maximum number of recursion steps when
482 searching for a filter for a job, in case a user
483 defines a circular filter rule.
484 - The PostScript filter would embed an invalid
485 requirements comment in some cases.
56e9c951 486 - Added support for embedded job tickets in PostScript
487 files.
5ca43bfd 488 - The PostScript filter now detects EPS files and should
489 better handle printing EPS files.
5ae53c1e 490 - The cancel command now ignores a trailing destination
491 name when cancelling a specific job ID (Solaris
492 compatibility).
879062a9 493 - The scheduler now rejects jobs with copies outside the
da956953 494 range of 1 to MaxCopies, inclusive.
495 - Added new MaxCopies directive to set the maximum
496 number of copies that a user can request.
879062a9 497 - The scheduler didn't block signals while it processed
498 others and when it forked processes.
5ae53c1e 499 - The scheduler checked for new jobs to print when
500 stopping a job. This caused jobs to restart before a
501 shutdown.
098f80c5 502 - Updated the CUPS startup script to better support
503 different timezones and to support the RedHat/Mandrake
504 init script functions, if available.
e426d516 505 - The scheduler did not properly handle backslashes in
506 banner files; it incorrectly assumed that "\c" should
507 always be replaced by "c", instead of only looking for
508 "\{" and replacing it by "{".
90ca6406 509 - The texttops filter didn't handle prettyprint=no.
510 - The text and HP-GL/2 filters didn't check for other
511 common duplex option names like cupsMarkOptions() did.
c56db294 512 - "lpoptions -x printer" no longer clears the "default
513 printer" status of the printer.
3f1897d4 514 - cupsTempFd() now stops trying to create a temporary
515 file after 1000 tries, and aborts on any error other
516 than EEXIST. This should prevent lp/lpr hangs due to
517 a bad or missing temporary directory.
5a3ef28d 518 - The lpadmin command did not send the right URI to the
519 scheduler when setting options on classes. This
520 caused a client-error-bad-request error.
e354b6e3 521 - The CUPS API convenience functions would attempt to
522 connect to the remote server name in a
523 "printer@server" printer name instead of dealing with
524 the default (usually local) server. Aside from
525 causing user confusion, the remote server name might
526 not be resolved properly, causing further problems.
f2320e2d 527 - "lp -q" would cause the "lp" command to segfault, as
528 the program would try to print the option letter that
529 caused the error using the wrong index into the
530 command-line; bugfix from Debian.
f2ffec40 531 - Fixed a minor inconsistancy in the encoding of boolean
532 attributes from printer options in
533 cupsEncodeOptions().
42ede8a2 534 - Added a FilterNice directive which sets the priority
535 of job filter processes that are run by the scheduler.
93704f20 536 - Added Solaris x86 USB printer support.
34f927d3 537 - The USB backend now reports both the ulpt and unlpt
538 devices under *BSD.
78ab59ae 539 - The "lpstat -o" command would truncate the
540 "printer-jobid" string if it was longer than 21
541 characters.
542 - The PJL-based MIME type rules now look in the first
543 1024 bytes instead of just the first 512 bytes to find
544 the language mode.
545 - The image file types are now listed explicitly in the
546 mime.convs file so that additional image file formats
547 do not use the standard CUPS image filters by default.
548 - Updated the Software Programmers Manual to include
549 all of the CUPS API functions.
cefea041 550 - ppdOpen*() no longer sorts choices for an option.
ce691c0f 551 - The web interface now enforces constraints in PPD
552 files when configuring a printer.
3733593d 553 - When stopping a printer, the scheduler didn't set the
554 printer state before stopping the current job.
a56289b6 555 - The cupsaddsmb utility now lists all data files for
556 Win9x and WinMe clients when installing that Windows
557 driver.
997cf8b0 558 - Jobs submitted to a class now bounce immediately to
559 the next available printer rather than waiting until
560 that printer is available.
561 - Filters and backends now also get the CLASS
562 environment variable set when a job is printed to a
563 printer class instead of a normal printer.
564 - Added French translations of the web interface, CUPS
565 Overview, Software Administrators Manual, and Software
566 Users Manual contributed by Marian REYT-LLABRES.
6b7de82f 567 - Added several "hint" messages for common configuration
568 problems that are stored in the error_log file.
569 - httpSeparate() now unquotes %xx characters in the
570 username:password field of a URI.
5fe35f41 571 - When starting the scheduler in daemon mode, the parent
572 process now waits for the child to signal it is ready
573 to accept connections.
574 - Added -F option to cupsd to run cupsd in the
575 foreground but detach from the controlling terminal
576 and current directory.
577 - The scheduler did not reload jobs when receiving a HUP
578 signal; this would cause problems since the pointers
579 into the file type database would no longer be valid
580 for existing jobs.
581 - The scheduler did not save the network interface list
582 update time, thus no caching of the network data was
583 actually provided.
584 - Updated the SuSE PAM configuration file.
9ba7fc54 585 - The LPD backend now supports a "reserve" option and no
586 longer reserves a priviledged port by default.
bdfe4c00 587 - The cupsaddsmb command now continues past printers
588 that do not have a PPD file to export.
19f699df 589 - The lpstat command didn't treat printer names as
590 case-insensitive.
591 - The lpstat command now reports the printer location
592 attribute with "lpstat -l -p".
c5488f2f 593 - Fixed a bug in the vsnprintf() emulation function,
594 which was used on old versions of HP-UX, IRIX, and
595 Solaris.
b91c8a76 596 - The number-up option was incorrectly being used when
597 printing banner pages.
4f759211 598 - Added support for Greek and Slovak PPD files.
aa37e40e 599 - CUPS now supports printer names containing any
600 printable character, e.g. "123-abc", "foo-bar", etc.
d958c5cf 601 - The null filter was not supported in mime.convs due to
602 a bug in the filter validation code.
3a74d6bf 603 - Changes in the default printer and printer attributes
604 were not always reflected in the generated printcap
605 file.
8ce19460 606 - Implicit classes did not inherit the location or
607 description from member printers.
fabb006b 608 - The httpGetHostByName() function did not handle
609 hostnames that started with a number.
1f1822fd 610 - Updated the filters to use the %cupsRotation comment
904eef76 611 instead of %%Orientation to auto-rotate pages, since
612 the use of %%Orientation is inconsistent.
d9e72533 613 - Added the RootCertDuration directive to control how
614 often the root authentication certificate is updated.
375a0ad5 615 - Increased the size of the IPP write buffer to 32k to
616 allow for larger attribute values and to provide more
617 efficient output of large numbers of attributes.
7ed5d5f2 618 - The polling daemon now retries the initial connection
619 to the remote server; this fixes a problem when the
620 remote server is unavailable when the scheduler starts
621 up...
19e7b382 622 - The scheduler didn't validate Digest users against the
623 system group(s), so Digest and BasicDigest
624 authentication didn't work for administration
625 operations.
103abc03 626 - The scheduler now passes the SHLIB_PATH environment
627 variable to child processes (HP-UX shared libraries)
06415a96 628 - The scheduler now maps accesses from the loopback
629 interface to "localhost".
630 - The cups-lpd mini-daemon sent a status code byte in
631 response to queue state commands, but those commands
632 only return textual data.
633
634
7680b71d 635CHANGES IN CUPS V1.1.15-1
636
637 - The lpc and lprm sources didn't include the CUPS
638 string function header, which is required on systems
639 that don't have their own snprintf() function.
640 - The French manpage Makefile tried to install the
641 language subdirectories when it (obviously) didn't
642 have to.
643
644
74cfdb8b 645CHANGES IN CUPS V1.1.15
646
dab1a4d8 647 - Updated the CUPS license agreement for the new MacOS
648 license exception.
611e4623 649 - The printer-info attribute now defaults to the printer
650 name if no value has been set.
52900e4c 651 - ppdOpen() and friends now add an "Auto" InputSlot
652 option if none is provided to automatically select the
653 correct tray.
ed6078a4 654 - Updated the ppdEmit() and ppdEmitFd() functions to
655 (re)mark the correct PageSize or PageRegion option
656 depending on the selected ManualFeed or InputSlot
657 options.
658 - ppdEmitFd() didn't handle custom page sizes.
659 - Darwin uses <pam/pam_appl.h> instead of
660 <security/pam_appl.h>.
fba7409c 661 - The jobs.cgi web interface now handles all job
662 operations, allowing the administrator to allow "job
663 administrators" or operators to manage jobs (but not
664 queues) on the server.
665 - The cupsDoFileRequest() function now checks if the
666 filename passed into the function is a directory, and
667 returns the IPP_NOT_POSSIBLE error if so.
668 - New SCSI printer backend.
a594463b 669 - Cleaned up handling of locales with trailing character
670 set definitions.
a319615f 671 - Fixed handling of invalid PPD attributes inside
672 OpenUI/CloseUI.
b92c5a4f 673 - Fixed a problem with SSL and the job, printer, and
674 admin CGIs on ports other than 443.
b47f3ce5 675 - The scheduler didn't handle AuthClass properly.
e6fc9c68 676 - Added French translation of man pages.
a8ee4682 677 - Updated the text filter to support the const_cast,
678 dynamic_cast, and static_cast keywords in ISO C++.
def978d5 679 - Now use strlcat() and strlcpy() (or emulation
680 functions) for easier string/buffer protection.
7b40ae49 681 - The auto-generated printcap/printers.conf files now
682 have a small comment header explaining where the file
683 comes from...
6df23e27 684 - The PostScript filter now supports 6, 9, and 16-up
ed6078a4 685 output, as well as new page-border and
6df23e27 686 number-up-layout options.
415199da 687 - The lpoptions command didn't set options properly when
688 using the default printer.
689 - Added ConfigFilePerm and LogFilePerm directives.
690 - Increased maximum size of MIME types to IPP_MAX_NAME
691 to allow for longer printer names.
692 - No longer create remote printers when loading job
693 history data.
694 - The printer-make-and-model attribute wasn't set when
695 the PPD file didn't contain a NickName attribute.
696 - Now handle PPD files with translation strings longer
697 than 80 bytes - they are truncated if they go over...
c47e97cc 698 - The scheduler didn't handle signals until after it
699 loaded the configuration files the first time; this
700 caused problems on some installations that would
701 restart the scheduler as the system booted into run
702 level 3.
703 - Now throttle broadcasts like we do for polling.
0203af93 704 - Fixed a bug in the reading of PPD files using CR's
705 instead of CR LF's or LF's.
151718ce 706 - The scheduler would crash if cupsd.conf contained a
707 BrowseProtocols line with no protocols listed.
b05e8e24 708 - The HTML job operation templates now link back to the
709 destination printer or class.
69d74c4b 710 - The serial backend now detects USB serial devices.
238bae16 711 - The LPD mini-daemon (cups-lpd) now passes the
712 job-originating-host-name attribute to the scheduler
713 (cupsd).
a4e23897 714 - Updated the IPP backend to reconnect after downgrading
715 from IPP/1.1 to 1.0, and when sending requests to HP
716 JetDirect interfaces that don't support HTTP
717 Keep-Alive like they should.
1cf29e95 718 - Now pass NLSPATH and DYLD_LIBRARY_PATH environment
719 variables, if defined, to CGI and job processes.
720 - Removed the pstoraster filter (based on GNU
721 Ghostscript 5.50) and now provide the raster "driver"
722 and patch file necessary to use the current GNU
723 Ghostscript 7.05 release.
724 - Removed unnecessary fonts and updated the Courier and
725 Symbol fonts to the latest versions to better support
726 non-ISOLatin1 text.
727 - The text filter now always embeds the Courier and
728 Symbol fonts to ensure that they contain the full set
729 of glyphs.
576b82ca 730 - The lp and lpr commands now only override the SIGINT
731 handler if it is not being ignored (patch from Robert
732 Ambrose for some interactive software that catches
733 SIGINT and will gracefully cancel the print...)
350807be 734 - The PostScript image filter (imagetops) now supports
735 printing CMYK images using the CMYK colorspace.
736 - The image filters now support CMYK JPEG files, and
737 correctly handles the inverted files from Photoshop
738 (which seems to save RGBW data, not CMYK...)
e3bf38b3 739 - Added a "check" target to the top-level makefile to
740 conform with GNU standards (same as "test").
746265a5 741 - The IPP code didn't always map the POSIX locale "C" to
742 the proper IPP language code.
32f78676 743 - The cupsaddsmb program was updated to use the
744 setdriver command instead of addprinter.
934ef66d 745 - Banner pages were not handled properly for implicit
746 classes.
7200e26c 747 - When tunneling to a remote system using SSH, the
748 printer URIs for local printers on the remote system
749 did not reflect the correct port number.
d7a9de63 750 - The Allow, Deny, BrowseAllow, BrowseDeny, and
751 BrowseAddress directives now support the network
752 interface names "@LOCAL" and "@IF(name)" for access
753 control and browsing based on the current interface
754 addresses instead of fixed names or IP addresses.
2a55786c 755 - The texttops filter did not properly recognize the
756 "nowrap" (wrap=false) option.
83575f2d 757 - The InstallableOptions group name in a PPD file is now
758 translated separately (CUPS_MSG_OPTIONS_INSTALLED) so
759 that UIs can accurately detect the presence of this
760 group.
f4647930 761 - The scheduler no longer keeps job history data for
762 remote printers on the client (just on the server.)
4c2096b8 763 - The parallel and USB backends now retry if the backend
764 detects that the printer is not connected to the
765 system (rather than stopping the queue...)
766 - The network backends now retry if the backend detects
767 that the printer is not connected to the network or is
768 unreachable (rather than stopping the queue...)
c672a858 769 - The cupsGetDests() function no longer lists options
770 and instances for printers that no longer exist.
31e65f97 771 - The scheduler now converts the document language to
772 the correct LANG string.
8c47c4b4 773 - The cupsaddsmb program now supports alternative CUPS
774 and SAMBA server names.
40a0e1d1 775 - The PostScript filter now supports the Orientation
776 comment and rotates the page as needed automatically.
f915b00f 777 - Revamped the makefiles slightly to use automatically
778 generated dependencies.
779 - Build fixes for OS X.
a1028786 780 - The TIFF reading code depended on the newest version
781 of libtiff; now conditionally compile that portion of
782 the loader.
bbc1bfe5 783 - The PPD code now decodes all JCL options in the
784 JCLSetup group, not just those options that start with
785 the prefix "JCL".
267cf96a 786 - The backends now read print data using the read()
787 system call to ensure that the current page is printed
788 while the next page is being processed.
2f7be6ff 789 - The pdftops filter did not support shading type 3
790 (radial fill) for the "sh" operator.
dab1a4d8 791 - The cups-polld program now throttles the local
792 broadcasts of polled printers and classes so that the
793 local system is not overwhelmed with hundreds of
794 printers and classes all at once.
795 - Updated the serial backend to support 230,400 baud for
796 the Linux PPC port.
59168282 797 - The cupsGetJobs() function wouldn't report completed
798 jobs that did not have a document-format attribute
799 value.
1c9c423b 800 - The cupsEncodeOptions() function now maintains a table
801 of known boolean and numeric options, and encodes all
802 other options as strings.
f918a565 803 - Now add a newline before the end-of-page code in the
804 PostScript filter; this fixes a problem with files
805 that don't end with a newline.
a28d12c5 806 - The image filters looked for the "orientation" option
807 instead of the correctly named "orientation-requested"
808 option.
74cfdb8b 809 - The cupsEncodeOptions() function now handles mixed
810 integers and ranges.
811 - New translation guide for developers to provide native
812 language support for CUPS.
813
814
ee8b7dd3 815CHANGES IN CUPS V1.1.14
816
843779ef 817 - The ippRead() function did not verify that the
ba31b514 818 attribute name length or string with language value
819 was not larger than the read buffer.
e2943c5f 820 - The scheduler set the signal handlers before loading
821 the configuration files the first time; this prevented
822 the RunAsUser directive from blocking server reloads.
5fd84fcc 823 - Added Swedish message catalog.
0e1f4bec 824 - The parallel backend now recognizes the /dev/printers
825 device directory under Linux 2.4.x.
ba31b514 826 - MacOS X fixes.
827 - The cupsaddsmb utility sent the server name after the
828 user information when executing the rpcclient program.
829 This caused problems with some versions of SAMBA
830 2.2.x.
ee8b7dd3 831 - The IPP backend did not pass the requesting user name
832 when checking on the print job status. This prevented
833 it from waiting for the job to complete when
834 communicating with some IPP implementations that
835 require it.
836
837
d2503e02 838CHANGES IN CUPS V1.1.13
839
28a96fe2 840 - The lpstat command did not report jobs submitted to
841 regular printer classes.
0f74081c 842 - The texttops filter didn't use sufficient precision
843 when positioning text with some values of cpi and lpi.
844 This could cause the alignment of text to stray.
0ffae44c 845 - cupsGetDests() didn't merge the options from the
846 /etc/cups/lpoptions file with ~/.lpoptions - options
847 in ~/.lpoptions overrode them completely.
848 - Added support for KOI8-R and KOI8-U character sets,
849 and added several Russian message catalogs.
bd726d0d 850 - The scheduler put the wrong timezone offset in the log
851 files (e.g. +0500 instead of -0500 for EST...)
852 - The scheduler did not ignore trailing whitespace in
853 *.convs files.
db911fcb 854 - The scheduler now forces all processes to exit (kill
855 -9) when it is stopped. This prevents parallel and
856 USB devices from running in the background after cupsd
857 goes away.
7c587866 858 - The cupsParseOptions() function didn't skip trailing
859 whitespace after quoted values.
c3026ddc 860 - More changes to support CUPS on OS/2.
24e80caf 861 - Added Simplified Chinese message catalog.
9495ba14 862 - Added PAM support for IRIX.
c6e1ca5d 863 - The cupsGetPPD() function didn't remove the @server
864 portion of the printer name, and since it would
865 connect immediately to the remote server instead of
866 the local server, the printer would not be found.
8b8cca8e 867 - Classification and page labels were not rotated to
868 match the page orientation.
9ae34eb7 869 - Now set the TCP "no delay" option on network
870 connections to improve performance/response time.
871 - Improved the IRIX printing tools support with patches
872 from Andrea Suatoni.
873 - Added a new PrintcapGUI directive to specify the GUI
874 option panel program to use for the IRIX printing
875 tools support.
876 - The cupsGetDests() function did not check to see if a
877 user-defined default printer (set via lpoptions) still
878 existed.
879 - The pstops filter no longer assumes that the default
880 dictionary is writable when doing N-up processing.
bbfcd9c7 881 - The pstops filter now supports printing N-up with the
882 page-set option.
873a6f43 883 - The imagetoraster filter now supports direct printing
884 of CMYK image data without conversion/correction.
d1c2727f 885 - The IPP backend now reports printer state/error
886 conditions when possible (toner low, media empty,
887 etc.)
bd73c81f 888 - The lpstat command now supports the (undocumented)
889 IRIX -l option ("-lprintername") for a compact job
890 listing for a printer.
891 - The lpstat command now includes printer date/time
892 information in the output (always Jan 01 00:00) to
893 make third-party tools happy.
18843e59 894 - The text filter now supports non-integer cpi and lpi
895 values.
dd5f3453 896 - The Margins field in the CUPS raster header was not
897 initialized by the pstoraster filter.
9aa1f763 898 - Added --with-optim="flags" option to configure script.
899 - Updated the Italian message translations.
900 - Updated the cups.list file to install the correct
901 files.
902 - The pstoraster filter accessed the third element of a
903 2 element array.
5f46b7d1 904 - The scheduler did not setup a status pipe for polling
905 processes, so error messages went to whatever file
906 descriptor 2 was pointing to when they were started.
5fb5dab7 907 - The httpMD5Final() function didn't put a colon between
908 the password and nonce strings.
c5de57af 909 - The pstops filter did not default to Binary data for
910 "%%BeginData:".
4a7e6692 911 - The pstops filter did not stop processing when a line
912 containing a CTRL-D is seen.
aba2fa7e 913 - The scheduler no longer replaces the JobSheets values
914 from the printers.conf and classes.conf files with the
915 classification level, if set. This way the original
916 banner settings are preserved when classification
917 levels are changed or turned off.
8d5eb22e 918 - The serial backend didn't drain the output queue, nor
919 did it restore the original settings.
d2503e02 920 - Updated the default system group under MacOS X.
921 - If no SystemGroup was defined in cupsd.conf, the
922 system default group was not used.
923 - The cups-lpd mini-daemon now supports LPD clients that
924 send multiple control files.
925 - httpConnectEncrypt() now always uses encryption for
926 connections on port 443, since port 443 is reserved
927 for the "https" scheme.
928 - Group authentication via certificates did not work
929 from the web interface for accounts other than
930 "root".
931 - The serial port backend did not clear the OPOST
932 option, which could cause problems with some printers.
933 - The cups-lpd mini-daemon didn't lookup the client IP
934 address properly.
935 - The parallel backend now identifies the polled and
936 interrupt-driven devices under *BSD.
937 - The scheduler allowed the "always" encryption mode
938 inside a Location, which is not valid.
939 - The CUPS startup script now checks for the timezone
940 information under Linux.
941 - Now also map the sides attribute to the JCLDuplex
942 option (if present) in PPD files.
943 - Updated pdftops to Xpdf 0.93a.
944 - Added support for MD5 passwords under Slackware.
945 - Added new AuthType BasicDigest that does Basic
946 authentication using the MD5 password file managed by
947 the lppasswd command.
948 - The banner page attribute substitution code now
949 retains {name} sequences in banner files when the
950 named attribute is undefined. Use {?name} to
951 conditionally substitute an IPP attribute.
952 - The scheduler now ensures that the ServerRoot
953 directory and configuration files are owned by and
954 writable by the User and Group in cupsd.conf.
955 - The USB backend now lists all USB printer devices
956 regardless of whether a printer is connected or not.
957 This allows new USB printers to be connected without
958 restarting cupsd.
959 - Added some more minor performance tweeks to the IPP
960 protocol code to reduce copying and array indexing.
961 - The cupsaddsmb utility now uses the -c option with
962 smbclient and rpcclient to avoid the read length limit
963 for commands on the standard input.
964 - Added an include file to the CRD handling code in
965 pstoraster so that it would compile properly on 64-bit
966 pointer platforms...
967
968
969CHANGES IN CUPS V1.1.12
970
971 - Added "Polish" to the list of known languages for PPD
972 files.
973 - Added missing directory definition to cups-config.
974 - The CUPS-Move-Job operation did not set the
975 destination type for the new destination.
976 - The CUPS-Add-Printer operation did not support the
977 allow=all or deny=none values to clear the per-user
978 printer ACLs.
979 - The SetPrinterAttrs() function did not handle invalid
980 PPD files that were missing the required NickName
981 attribute. It now looks for NickName, ModelName, and
982 then substitutes the string "Bad PPD File" for the
983 printer-make-and-model attribute.
984
985
986CHANGES IN CUPS V1.1.11
987
988 - Added support for embedded TrueType fonts in PDF
989 files.
990 - Added support for PostScript functions in PDF
991 files.
992 - Added new "cupsaddsmb" utility for exporting
993 CUPS printer drivers to SAMBA/Windows clients.
994 - Added preliminary support for Darwin/MacOS X.
995 - The CUPS-Add-Printer operation no longer allows
996 arbitrary scheme names in device URIs to be used - it
997 now restricts the available schemes to those found in
998 the device list (lpinfo -m).
999 - The ippRead() and ipp_read_file() functions could not
1000 handle more than IPP_MAX_VALUES (100) values in a
1001 1setOf attribute. These functions have been updated
1002 to dynamically allocate more memory as needed, and the
1003 IPP_MAX_VALUES constant now represents the allocation
1004 increment. [this caused some versions of the
1005 GIMP-print drivers to fail since the number of media
1006 options exceeded 100...]
1007 - The scheduler could crash when BrowseShortNames
1008 was set to "No".
1009 - The scheduler did not prevent MaxClients from being
1010 set to 0, which could cause the scheduler to go in an
1011 infinite loop when accepting a request.
1012 - Made some performance optimizations in the ippRead()
1013 functions to make IPP request/response processing
1014 faster.
1015 - The accept/reject/enable/disable command did not
1016 support properly support the "-h" or default
1017 server name.
1018 - The scheduler did not save the quota configuration
1019 when the job-quota-period attribute was set to 0.
1020 - The LPDEST and PRINTER environment variables did not
1021 support printer instances.
1022 - The text filter now handles more types of boldface and
1023 underline formatting.
1024 - The cupsTempFd() function did not fail if the
1025 temporary directory did not exist; this would cause it
1026 to loop indefinitely instead of returning an error
1027 (-1).
1028 - Stopping (disabling) a printer class did not stop jobs
1029 from printing to printers in that class.
1030 - The cupsGetDests() function was sending the
1031 requested-attributes attribute as a name instead of a
1032 keyword; this caused a serious performance problem on
1033 slower systems since more information had to be
1034 transferred from server to client.
1035 - The web interfaces did not always quote < and & in
1036 things like the job title. This had the potential for
1037 browser-based security violations (on the browser's
1038 machine); bug report from SuSE.
1039 - The scheduler now treats unauthenticated usernames as
1040 case-insensitive when doing quota and allow/deny
1041 processing.
1042 - The lp command sent the "request ID is ..." message
1043 to stderr instead of stdout...
1044 - The PostScript filter (pstops) now handles EPS files,
1045 adding a showpage command to the files as needed.
1046 - The configure script checked for the <stdlib.h> header
1047 file before the JPEG libraries; since the JPEG headers
1048 can define HAVE_STDLIB_H, the configure check would
1049 cause the JPEG check to fail on some systems.
1050 - The scheduler now supports localized banner files,
1051 using the subdirectory approach, e.g. the "es"
1052 subdirectory under /usr/share/cups/banners is used for
1053 the Spanish banner files.
1054 - Updated the scheduler so it knows the correct
1055 language abbreviation to use for all supported
1056 PPD LanguageVersion values. The new code also
1057 supports country codes as well, so "English-GB"
1058 maps to the "en_GB" locale.
1059 - The cups-lpd mini-daemon did not support
1060 anonymous printing (no username specified).
1061 While the username is REQUIRED by RFC-1179,
1062 MacOS clients do not send the REQUIRED username
1063 information when printing via LPD.
1064 - Added many warning and informational messages
1065 to cups-lpd where they were missing.
1066 - Added Czech message file contributed by SuSE.
1067 - The cups-lpd mini-daemon now returns a non-zero
1068 status if an invalid destination or job ID is
1069 provided.
1070 - The scheduler did not honor the KeepAlive setting in
1071 cupsd.conf.
1072 - Increased the size of the file read/write buffers to
1073 32k.
1074 - *BSD static library creation fixes.
1075 - Use mkstemps() instead of tmpnam() in pdftops whenever
1076 possible.
1077 - Added httpGetHostByName() function as a wrapper around
1078 gethostbyname() - some implementations of this
1079 function do not support IP addresses (e.g. MacOS X.)
1080 - Added casts to all printf's of file lengths, since
1081 there is currently no standard way of formatting long
1082 long values.
1083 - The client filename field was not cleared in all
1084 instances, resulting in old form data being submitted
1085 to CGIs.
1086 - The httpConnect*() functions now try all available
1087 addresses for a host when connecting for the first
1088 time.
1089 - The pstoraster filter would "lose" all drawing
1090 commands when the PageSize was set but the printer
1091 bitmap was not reallocated. This was most noticeable
1092 with the output from StarOffice 6 beta and would
1093 result in a blank page being output...
1094 - The IPP backend was sending a PAGE comment even when
1095 printing the output from a filter (it should only send
1096 page comments when printing files directly...)
1097 - The pdftops filter didn't properly map glyph names of
1098 embedded Asian TrueType fonts.
1099 - Changed the CUPS startup script to look for a program
1100 named "cupsd", not just any program with "cupsd" in
1101 the name (this caused the apcupsd UPS monitoring
1102 daemon to be stopped/restarted...)
1103 - The CUPS-Move-Job operation did not change the
1104 internal destination name for held jobs, so moved (but
1105 held) jobs would still show up as queued on the
1106 original destination.
1107 - The cups-polld program didn't send the
1108 requested-attributes attribute in the
1109 CUPS-Get-Printers and CUPS-Get-Classes requests, which
1110 made it use more CPU and bandwidth than required.
1111 - The scheduler and CUPS API incorrectly added a
1112 job-sheets-default attribute for remote printers. This
1113 caused banner pages to be omitted from client system
1114 prints.
1115
1116
1117CHANGES IN CUPS V1.1.10-1
1118
1119 - Minor fixes to the filter, systemv, and template
1120 makefiles to install files properly.
1121
1122
1123CHANGES IN CUPS V1.1.10
1124
1125 - Added a driver for DYMO label printers.
1126 - Added new ClassifyOverride directive to allow users
1127 to override the classification of individual jobs.
1128 - Added new BrowseProtocols directive to control which
1129 browse protocols are used (currently CUPS and SLP).
1130 - Added SLPv2 support (thanks to Matt Peterson for
1131 contributing the initial implementation for CUPS.)
1132 - Adding a raw printer on a remote CUPS server now
1133 correctly redirects PPD file requests to the remote
1134 server.
1135 - The serial backend now limits writes to 1/10th
1136 second worth of data to avoid buffer overflows
1137 with some types of flow control.
1138 - The scheduler did not properly process PUT requests,
1139 so configuration files could not be uploaded to the
1140 server.
1141 - The scheduler did not strip trailing whitespace on
1142 lines in the configuration files.
1143 - The httpWrite() function did not transition the PUT
1144 request to the HTTP_STATUS state to get the status
1145 from the server.
1146 - The scheduler did not properly handle trailing null
1147 ("-") filters when testing a driver that sent data
1148 to the file: pseudo-backend.
1149 - The IPP backend now only sends a document-format of
1150 "application/vnd.cups-raw" when printing to another
1151 CUPS server using a local printer driver or interface
1152 script. Previously the job's document format was
1153 used, which was incorrect.
1154 - The lpadmin command didn't use the ppd-name attribute
1155 with the -m option; this prevented the use of the
1156 "raw" model from the command-line.
1157 - The pstoraster filter output draft (1-bit) 6-color
1158 output in the wrong order; this resulted in yellow
1159 being printed instead of black on Stylus Photo
1160 printers.
1161 - The pdftops filter did not have the Japanese and
1162 Chinese text support compiled into it.
1163 - The IPP and AppSocket backends did not clear the
1164 "waiting for print job to complete" status message,
1165 which caused some confusion... :)
1166 - The serial backend now opens the port in "no delay"
1167 mode to avoid DCD detection problems with some OS's.
1168
1169
1170CHANGES IN CUPS V1.1.9-1
1171
1172 - The configure script did not substitute the
1173 correct user and group names.
1174 - The configure script did not use the full path
1175 to the install-sh script when it was used.
1176 - The pstoraster filter did not correctly support
1177 DuplexTumble mode for printers that used flip
1178 duplexing.
1179 - The cups.list.in file was missing from the
1180 distribution.
1181 - The New DeskJet series driver did not use the
1182 correct OrderDependency for the Duplex option.
1183 - Use read() instead of fread() to read piped
1184 print files in lpr/lp. This avoids a bug in the
1185 HP-UX 10.20 fread() function.
1186 - Updated the pstoraster filter to use the MIPS_FIXADE
1187 system call under IRIX to fix bus error problems on
1188 R12000 processors (Ghostscript is not 64-bit clean...)
1189 - Some Xerox PPD files (most notably the Phaser 790)
1190 have illegal whitespace in the option keyword in the
1191 OpenUI line. This caused the PageRegion option to not
1192 be recognized properly for the Phaser 790.
1193
1194
1195CHANGES IN CUPS V1.1.9
1196
1197 - Revamped the configure script to use a modular
1198 approach for the various tests.
1199 - Added --with-openssl-* options to properly reference
1200 the OpenSSL libraries in DSOs.
1201 - Added --with-cups-user and --with-cups-group
1202 options to specify the default user and group for
1203 CUPS.
1204 - Added AIX shared library support.
1205 - Added AIX device discovery for the serial and
1206 parallel ports.
1207 - Now use install program or script to install
1208 directories, files, and symlinks.
1209 - Updated pstops filter to use strict handling of EPS
1210 files embedded in a PostScript document. The %%EOF
1211 handling in 1.1.8 caused some dvips files not to
1212 print.
1213 - Fixed yet another memory allocation bug in pstoraster
1214 that would cause it to crash. This fix also ensures
1215 that all memory allocations are done on (at least) a
1216 64-bit boundary.
1217 - Fixed Digest authentication - httpGetSubField() didn't
1218 skip the Digest keyword.
1219 - The scheduler did not properly handle Digest
1220 authentication with the new multiple-group support.
1221 - The scheduler did not allow usernames that were
1222 not in the UNIX password file to be used for Digest
1223 authentication from passwd.md5.
1224 - The scheduler could not scan PPD files that only used
1225 a carriage return (i.e. MacOS PPD files); the new code
1226 is also about 40% faster, so servers with thousands of
1227 PPD files should start much faster now.
1228 - The scheduler now stores the PPD file size and
1229 modification times in the ppds.dat file, so it can now
1230 incrementally update the PPD database from the model
1231 directory, resulting in significantly faster startup
1232 times.
1233 - The lpinfo command did not return a non-zero status
1234 code if an error occurred.
1235 - Fixed a bug in the scheduler's UpdateJob() function.
1236 Basically, all jobs shared the same status buffer, and
1237 the "buffer start" pointer could point to 1 byte
1238 before the beginning of the buffer. The new
1239 implementation uses a separate buffer for each job and
1240 eliminates the buffer start bug.
1241 - The IPP backend would send N copies of a document if
1242 the receiving device didn't support the copies
1243 attribute, even if the upstream driver already added
1244 the necessary commands to generate the copies. This
1245 was most noticeable with HP printers where N * N
1246 copies would come out instead of N.
1247 - The PostScript filter (pstops) did not properly handle
1248 duplex printing on inkjet printers that provide this
1249 option. Copies would be put on the front and back
1250 sides of the duplexed page, and the filter did not
1251 output an even number of pages.
1252 - The backends always caught SIGTERM after they
1253 connected to the printer. This prevented raw jobs
1254 from being cancelled early.
1255 - The cupsSetDests() function now removes any printers,
1256 instances, and options that are not defined by the
1257 user or server. This should prevent old system-wide
1258 options from being used in individual user accounts.
1259 - Updated the EPSON printer driver and added PPDs for
1260 the newer EPSON Stylus printers that only support the
1261 "ESC i" graphics command.
1262 - The lpadmin command didn't allow you to add remote
1263 printers to a local class.
1264 - The lpadmin command didn't allow you to set the
1265 options (quotas, etc.) for a class.
1266 - The scheduler did not load or save the
1267 job-sheets-default attribute for classes.
1268 - The scheduler did not automatically recreate remote
1269 printers that were part of a class.
1270 - It was possible for a printer class to list the same
1271 printer more than once.
1272 - The scheduler now makes a backup copy of classes.conf
1273 and printers.conf before writing the new file.
1274 - The lppasswd program incorrectly asked for a new
1275 password when deleting an existing MD5 password
1276 account.
1277 - The scheduler did not match "/printers/name.ppd"
1278 against a location of "/printers/name".
1279 - The client code did not always handle HTTP encryption
1280 upgrades properly.
1281 - The client code now caches the last Digest password so
1282 it can retry using a new resource path or nonce value,
1283 which are included in the MD5 sum sent to the server.
1284 This should eliminate unnecessary password prompts
1285 when using Digest authentication.
1286 - The lppasswd command didn't have a man page.
1287 - Updated the PJL detection rules to allow the universal
1288 escape to occur anywhere in the first 128 bytes of the
1289 file.
1290 - The cups-polld program would poll servers continuously
1291 with no delay if there was an error contacting the
1292 server.
1293 - The IPP backend would send an empty job-name or
1294 requesting-user-name attribute if the corresponding
1295 job attribute was an empty string. While this is
1296 allowed by the IPP specification, some HP JetDirect
1297 implementations return a client-error-bad-request
1298 error if an empty name attribute value is received.
1299 The new code only sends these attributes if they are
1300 not the empty string.
1301 - At least some versions of the HP JetDirect firmware
1302 do not correctly implement IPP. Added additional
1303 checks to the IPP backend to eliminate extra,
1304 unsupported attributes which should normally be
1305 ignored by a compliant IPP device.
1306 - The scheduler did not copy the complete list of
1307 supported file types into the
1308 document-format-supported attribute. This caused
1309 clients to not send the local file type (such as
1310 application/vnd.cups-raw for raw print files) and the
1311 corresponding bad output in some cases.
1312 - The scheduler did not fully copy attributes from a
1313 set-job-attributes request - string attributes were
1314 only referenced, which could cause cupsd to crash
1315 or behave irratically.
1316 - The lp command didn't send the right value for the
1317 job-hold-until attribute when "-H resume" was
1318 specified.
1319 - The IPP backend now returns as soon as a job is
1320 completed or reported as "pending-held".
1321 - Added new ImplicitAnyClasses and HideImplicitMembers
1322 directives to the cupsd.conf file to make implicit
1323 classes more usable/transparent to the user.
1324 - Clients can now (with the appropriate authentication)
1325 retrieve and update the server configuration files
1326 using HTTP GET and PUT requests.
1327 - The web interface didn't allow you to modify the
1328 location or description of the printer.
1329 - The pdftops filter now uses its own temporary file
1330 function to work with PDF files using LZW compression
1331 (which use the uncompress program or gunzip)
1332 - The SystemGroup directive now supports specification of
1333 multiple groups.
1334 - Added new Include directive to cupsd.conf, a la
1335 Apache.
1336 - Added new pseudo-driver/PPD called "raw" that can be
1337 used to create/convert a raw queue. This also allows
1338 raw queues to be created in the web interface.
1339 - The pdftops filter didn't handle image objects that
1340 used JPEG and Flate compression together.
1341 - The pstops filter counted pages wrong when using the
1342 N-up and even/odd printing options. This prevented
1343 the page-ranges option from working properly.
1344 - Added another fix to pstoraster for a bus error
1345 condition caused by a lack of parenthesis in the
1346 Ghostscript code.
1347 - Added new "natural-scaling" option which scales the
1348 natural size of the image (percent of natural image
1349 size instead of percent of page size.)
1350 - The lppasswd program is now setuid to the CUPS user
1351 instead of root.
1352 - The PPD functions did not allow for PPD files that
1353 defined the page sizes and margins before the page
1354 size options.
1355 - The mime.types file now checks for the PJL "LANGUAGE =
1356 Postscript" command for PostScript files.
1357 - The scheduler did not truncate file: output files.
1358 - The PPD file reading code did not handle options with
1359 raw quotes (") in the human-readable names.
1360 - The pdftops filter now remaps the space character when
1361 (bad) PDF files contain a .notdef glyph for the space
1362 character.
1363
1364
1365CHANGES IN CUPS V1.1.8
1366
1367 - Updated spec file to generate separate cups-pstoraster
1368 package for pstoraster.
1369 - The spec file wasn't setting LOGDIR in the install.
1370 - The scheduler might restart a stopped printer after
1371 stopping a print job. Thanks to Florent
1372 Guiliani for finding this bug!
1373 - The init script showed run level 0 for the Red Hat
1374 chkconfig program. This is incorrect because Red Hat
1375 doesn't use run level 0 for shutdown scripts.
1376 - The IPP backend did not handle the
1377 client-error-not-found error when checking the status
1378 of the job that was sent. This caused remote queues
1379 to stop on client machines when the server had job
1380 history disabled.
1381 - Added httpConnectEncrypt() function to avoid
1382 performance penalty for setting up encrypted
1383 connections initially.
1384 - Use httpConnectEncrypt() in all client apps and in the
1385 CUPS API to ensure consistent usage of encryption
1386 throughout.
1387 - Jobs weren't queued to remote classes (fix from
1388 Richard Begg.)
1389 - AIX changes from Richard Begg.
1390 - Fixed the pstops fix for GNOME output - no longer use
1391 the page numbers in the %%Page: comment since GNOME
1392 puts a filename instead (!?@!#?!). There is still an
1393 issue with N-up printing since GNOME defines its fonts
1394 in the first page instead of the document setup section
1395 (pages must be independent according to the DSC spec)
1396 People with GNOME printing problems should consult bug
1397 #54489...
1398 - The imagetops filter produced PAGE: messages when
1399 generating PostScript for a non-PostScript printer
1400 (only affects page-label and Classification
1401 options.)
1402 - The updated pdftops filter was looking for an options
1403 file called xpdf.conf instead of pdftops.conf.
1404
1405
1406CHANGES IN CUPS V1.1.7
1407
1408 - Configuration script changes, including new
1409 "--with-docdir=/dir" option to relocate CUPS
1410 documentation and web content according to your
1411 favorite version of the FHS.
1412 - Documentation updates for encryption, SLP, etc.
1413 - New Software Test Plan and automated test script to
1414 test CUPS prior to installation.
1415 - All scheduler configuration files are now case
1416 insensitive to match Apache.
8372ad6b 1417 - Added support for Apache ListenBackLog, Require,
1418 Satisfy, <Limit>, <LimitExcept>, and LimitRequestSize
d2503e02 1419 directives.
1420 - Added support for all Apache log levels...
1421 - Added support for "double" HostNameLookups.
1422 - Added new "RunAsUser" directive to support non-root
1423 configurations on the standard (priviledged) ports.
1424 - Added support for non-root invocation of the lpd
1425 backend (does no reserve a priviledged port, which
1426 might not work with some LPD servers...)
1427 - Added new PrintcapFormat directive to control the
1428 output format of the printcap file (BSD or Solaris
1429 formats are supported at present.)
1430 - The CUPS directory service routines now handle
1431 ECONNREFUSED errors gracefully rather than shutting
1432 all browsing off.
1433 - ippErrorString() now returns the recommended error
1434 messages from the IPP/1.1 Model and Semantics
1435 document.
1436 - Fixed a minor IPP compliance issue with responses
1437 to requests without the attributes-charset or
1438 attributes-natural-language attributes.
1439 - Sun fix: need httpFlush() call for chunked IPP
1440 requests in cupsDoFileRequest().
1441 - httpConnect() now looks up "localhost" by name and
1442 by address (127.0.0.1) for users the go to the
1443 trouble of removing the required localhost entry
1444 in /etc/hosts or on their DNS server...
1445 - Added support for Linux 2.4.x devfs parallel port
1446 filenames (/dev/parallel/N).
1447 - cupsDo[File]Request() and cupsGetPPD() no longer
1448 block trying to reconnect to a crashed or inaccessable
1449 server.
1450 - Added new ppdEmitJCL() function to better handle
1451 PJL commands from PPD files.
1452 - A bug in UpdateJob() would cause the scheduler to
1453 consume 100% CPU until another request was submitted.
1454 - The cancel command did not support the "-" option to
1455 cancel all jobs on all printers.
1456 - The cancel and lprm commands did not support cancelling
1457 the next/current job in the queue.
1458 - The pdftops and pstoraster filters were using unsafe
1459 temporary file functions; while this is not a problem
1460 in normal configurations (the CUPS temporary directory
1461 is restricted), they now use the cupsTempFd() function.
1462 - The mime.types file was missing the recognition rule
1463 for Sun Raster images.
1464 - The admin CGI was passing a printer make string to
1465 ippSetCGIVars() that was being replaced in that
1466 function.
1467 - "lpoptions -l" would resave the options...
1468 - The EPSON drivers now send the "end packet mode"
1469 command when printing to USB devices.
1470 - The scheduler initialized certificates before loading
1471 the cupsd.conf file.
1472 - The scheduler used /dev/random to collect random data,
1473 which could block if insufficient entropy information
1474 had been collected by the kernel. Now use
1475 /dev/urandom.
1476 - Fixed a bug in the whitespace skipping code in
1477 httpGetSubField().
1478 - The LPD backend now supports a new "order" option:
1479 "lpd://server/queue?order=control,data" (default) and
1480 "lpd://server/queue?order=data,control".
1481 - The scheduler enforced a 30 second timeout on all
1482 clients regardless of the Timeout directive and if a
1483 CGI was currently running.
1484 - cupsParseOptions() now sets boolean options to
1485 option=true or option=false.
1486 - The "percent complete" calculations in the LPD backend
1487 could overflow on large files, causing the percentage
1488 to wrap to 0 every 40MB or so.
1489 - Fixed a memory reallocation bug in pstoraster that
1490 could cause it to crash.
1491 - The LPD backend now sanitizes the job title to avoid
1492 potential problems on remote LPD servers.
1493 - The lp command did not send the requesting-user-name
1494 attribute when altering a job.
1495 - The pstops filter did not handle PostScript files with
1496 lines longer than 8191 bytes.
1497 - The scheduler no longer uses inet_addr() to convert IP
1498 addresses in dot format (mmm.nnn.ooo.ppp) to the
1499 32-bit format, since it will not work for IPv6
1500 addresses.
1501 - New "Classification" directive to force labeling of
1502 the current classification on each page.
1503 - New "page-label" attribute to add per-page labels
1504 ("For Official Use Only", "Draft", etc.)
1505 - The scheduler now sets the HTTPS environment variable
1506 for CGI programs when a client connects using
1507 encryption.
1508 - Fixed a recursion bug in the scheduler that could
1509 cause cupsd to crash when a printer was removed.
1510 - The LPDEST and PRINTER environment variables didn't
1511 support instances.
1512 - Dropped the "file" backend from the device list that
1513 is reported, since it is only available for *testing*
1514 and should never be used in a production environment.
1515 The file: device can still be used, but it won't show
1516 up in the list of devices from lpinfo or the web
1517 interface.
1518 - Added support for /dev/lpa# parallel ports under *BSD.
1519 - Added META variables to the CGI header template to
1520 prevent caching of the results.
1521 - Fixed an unaligned memory buffer for the pstoraster
1522 clist states; this caused bus errors for some
1523 combinations of printers, drivers, and options.
1524 - Re-added black reduction for colorful colors; this
1525 helps to prevent dark colors from getting desaturated.
1526 (only used when converting RGB to CMYK)
1527 - Added two new directives - MaxJobsPerPrinter and
1528 MaxJobsPerUser - to allow an administrator to set
1529 the maximum number of pending jobs in a queue or
1530 submitted by a user.
1531 - The scheduler no longer stops a printer if it can't
1532 create the status pipe or run the filters or backend.
1533 This will allow heavily loaded servers to service
1534 clients or start print jobs as the load allows.
1535 - Fixed a bug in the Set-Job-Attributes code that could
1536 crash the scheduler (patch from Martin Zielinski)
1537 - cupsSetDests() did not quote option values with
1538 embedded spaces.
1539 - Added support for the Enable-Printer and
1540 Disable-Printer extension operations (same as
1541 CUPS-Accept-Jobs and CUPS-Reject-Jobs.)
1542 - The AppSocket and IPP backends now wait for the print
1543 job to be finished before exiting; this should prevent
1544 the loss of print jobs with older JetDirect firmware
1545 and make consecutive print jobs print faster.
1546 - The BMP loading code did not handle resolution values
1547 of 0. This is a problem with BMP image files produced
1548 by the GIMP.
1549 - The HTTP Upgrade code (upgrade to TLS encryption)
1550 bypassed the authentication checks.
1551 - The HTTP Upgrade code did not send a 426 status code
1552 to the client and end the current request. This caused
1553 a race condition between the client and server for the
1554 upgrade to TLS.
1555 - Fixed a bug in the EOF and Trailer detection code in
1556 the pstops filter.
1557 - The imagetoraster filter did not add the margins to
1558 the custom page size in the raster header.
1559 - The imagetops filter did not adjust the custom page
1560 size to the size of the printed image.
1561 - The imagetops filter did not include DSC comments
1562 which are required by some printers.
1563 - The imagetops filter did not insert newlines in
1564 Base85 encoded output, causing files to contain
1565 lines longer than 255 characters (violation of the
1566 DSC).
1567 - Added support for the DeskJet 900 series duplexer
1568 and CRET color modes in the HP driver.
1569 - Added support for PPD-defined margins in the HP
1570 driver.
1571 - Fixed the debugging output from pstoraster - the
1572 font list was not terminated by a newline.
1573 - Some versions of the HP-UX pam_unix authentication
1574 module apparently do not pass the appdata_ptr argument
1575 to the conversation function, preventing the scheduler
1576 from authenticating users using PAM under HP-UX. A
1577 workaround using a static variable has been added to
1578 address this problem.
1579 - Fixed a bug in the scheduler SortPrinters() function
1580 that could cause printers to disappear or the
1581 scheduler to crash when adding a printer.
1582 - Changed the pstops filter to not do per-page filtering
1583 if the file does not conform to at least version 3.0
1584 of the document structuring conventions. This seems
1585 to "fix" printing with broken apps.
1586 - The image filters did not handle older TIFF files that
1587 lacked the samples-per-pixel and bits-per-pixel tags.
1588 - Added new cupsGetJobs() and cupsFreeJobs() functions
1589 to manage print jobs.
1590 - cupsEncodeOptions() would encode names of 0 length and
1591 cupsAddOption() and cupsParseOptions() would add names
1592 of 0 length.
1593 - The scheduler might block waiting for status messages
1594 after starting a new print job. Thanks to Florent
1595 Guiliani for finding this bug!
1596
1597
1598CHANGES IN CUPS V1.1.6-3
1599
1600 - The configure script put the JPEG library before the
1601 TIFF library; this caused problems in some
1602 configurations since the TIFF library also supports
1603 JPEG compression of TIFF images.
1604 - Updated the configure script and makefiles to handle
1605 admin man pages with the "1m" extension (HP-UX, IRIX,
1606 Solaris, Tru64) and in odd directories (IRIX)
1607 - The updated cupsTempFile() function did not return
1608 the filename when called with a filename buffer of
1609 NULL (previously it used a static buffer.)
1610 - FreeBSD uses /dev/unlptN, but NetBSD and OpenBSD use
1611 /dev/ulptN.
1612 - DeletePrinter() didn't remove the printer from any
1613 classes it was a member of.
1614 - DeletePrinterFromClass() didn't preserve the
1615 implicit status of a class.
1616 - DeletePrinterFromClasses() didn't remove printers
1617 from implicit classes.
1618 - StartJob() didn't send the job-sheets, job-priority,
1619 and job-hold-until attributes to remote printers.
1620 - LoadAllJobs() was looking for job-sheets-completed
1621 instead of job-media-sheets-completed. This would
1622 prevent accumulation of page data after a restart
1623 of the scheduler.
1624 - The pstops and imagetops filters now generate copies
1625 using the appropriate method for a Level 1, 2, or 3
1626 printer since some Level 2/3 printers don't support
1627 the /#copies variable anymore.
1628 - The man page for cups-lpd did not mention the "-o"
1629 option.
1630 - The IPP backend didn't handle version-not-supported
1631 errors and revert to IPP/1.0 (previously it only checked
1632 for a bad-request error)
1633 - Caldera fix: lpc now reports unimplemented commands as
1634 unimplemented, not invalid.
1635 - Caldera fix: lpq didn't recognize BSD lpq "-a" option.
1636 - Caldera fix: lpr didn't recognize BSD lpr "-1", "-2",
1637 "-3", "-4", "-q", or "-U" options.
1638 - RedHat fixes: patches to GNU Ghostscript
1639 - SuSE fix: temp file creation patch to GNU Ghostscript
1640 (pstoraster).
1641 - SuSE fix: remove cgi-bin/abort.c and cgi-bin/email.c,
1642 which are not used.
1643 - SuSE fix: missing NULL check in cgi_initialize_post().
1644 - SuSE fix: potential buffer overflows in
1645 cgi_initialize_string().
1646 - SuSE fix: potential buffer overflows in
1647 ippSetCGIVars()
1648 - SuSE fix: more NULL checks in ppdOpen(); also make
1649 sure that all memory is freed on error to avoid memory
1650 leaks.
1651 - SuSE fix: Exit from child if setgid() or setuid()
1652 fails.
1653 - SuSE fix: Added setgroups() calls after setgid() and
1654 setuid() calls.
1655 - SuSE fix: potential buffer overflows in httpEncode64()
1656 calls.
1657 - SuSE fix: potential buffer overflows in httpSeparate()
1658 - SuSE fix: potential buffer overflows in ippWrite() for
1659 bad input.
1660 - SuSE fix: potential nul skip in ppd_decode() for
1661 missing hex digits.
1662
1663
1664CHANGES IN CUPS V1.1.6-2
1665
1666 - Added changes to support NetBSD startup scripts.
1667 - Added separate compiler options for pstoraster
1668 (Ghostscript) to avoid compiler-induced errors
1669 from Ghostscript's twisted code.
1670 - The mime.types file contained syntax errors.
1671 - Updated the *BSD USB device filenames to use
1672 the /dev/unlptN files so that the USB device
1673 is not reset prior to printing (causes print
1674 corruption on many printers)
1675 - Added new cupsTempFd() function to avoid serious
1676 security bug in glibc fopen() function. The glibc
1677 fopen() function unlinks a file before creating it,
1678 which opens up possible symlink attacks.
1679 - Now reject 0-length names in add-printer and add-class
1680 requests.
1681 - Fix for pstoraster when ZLIB is not available.
1682 - cupsGetPPD() didn't reconnect when a HTTP connection
1683 was lost.
1684 - SuSE fix: httpConnect() didn't check that the
1685 value from gethostbyname() was a valid IPv4 address.
1686 - SuSE fix: httpConnect() didn't allow file descriptor 0
1687 to be used for a socket.
1688 - SuSE fix: ippRead() didn't confirm that all values in
1689 a set were numeric or string types.
1690 - SuSE fix: lppasswd race condition fixes.
1691 - SuSE fix: directive names could overflow buffer when
1692 reading *.conf files.
1693 - SuSE fix: HEAD requests for PPD files did not use the
1694 same logic as GET requests.
1695 - SuSE fix: possible buffer overflow when adding
1696 /index.html to requested directory name.
1697 - SuSE fix: possible buffer overflow when converting
1698 IPP attributes to string options for filters.
1699 - SuSE fix: creating file: device output with mode 0666
1700 instead of mode 0600.
1701 - SuSE fix: creating job info files with mode 0640
1702 instead of 0600.
1703 - SuSE fix: don't rely on snprintf() for including
1704 system name in log filenames.
1705 - SuSE fix: add bounds checking when copying quoted
1706 and hex strings.
1707
1708
1709CHANGES IN CUPS V1.1.6-1
1710
1711 - Added configure check for getting the correct
1712 strftime() format string; %c is not Y2k safe,
1713 and %KC and NULL are not universally supported.
1714
1715
1716CHANGES IN CUPS V1.1.6
1717
1718 - Fixed another possible DoS attack in httpGets()
1719 - Added check for "LANGUAGE = PCL" and "LANGUAGE =
1720 POSTSCRIPT" in mime.types.
1721 - Resolution options were not being passed into the
1722 filter programs properly.
1723 - The default compiler options for GCC no longer include
1724 "-g3", which apparently is deprecated in newer
1725 versions of GCC.
1726 - CheckJobs() could cause cupsd to crash if a job is
1727 cancelled in StartJob().
1728 - The printers.conf and classes.conf files are now
1729 written with restricted permissions.
1730 - The round-robin algorithm used by FindAvailablePrinter()
1731 had problems; fixes contributed by Joel Fredrikson.
1732 - If LoadAllJobs() is unable to determine the file type
1733 of a print job, assume "application/vnd.cups-raw".
1734 - The web interface now provides a job_printer_name
1735 value for any corresponding job_printer_uri value.
1736 - The cups-lpd mini-daemon now logs the client address
1737 and hostname as well as all commands and errors in the
1738 syslog file.
1739 - The IPP backend now detects the supported file formats
1740 and only specifies the document format if it is
1741 supported. This makes IPP printing to network print
1742 servers and cards more reliable without affecting the
1743 capabilities of CUPS servers.
1744 - The time_at_xyz attributes are now converted to human-
1745 readable dates and times for the web interfaces.
1746 - The HP and EPSON sample drivers now correctly catch
1747 signals and eject the current page when a job is
1748 cancelled.
1749 - Fixed bug in CGI code - did not ignore control
1750 characters (e.g. newlines) in form data. This caused
1751 sporatic web interface problems.
1752 - The file type logging code in the scheduler referenced
1753 the optional document-format attribute; the new code
1754 uses the resolved MIME type instead.
1755 - The client.conf parsing code now removes trailing
1756 whitespace.
1757 - The MaxJobs directive was being treated as a boolean
1758 instead of an integer.
1759 - The scheduler would not timeout remote printers if
1760 BrowseInterval was set to 0.
1761 - The lpadmin command now supports setting of options
1762 and user-level access control.
1763 - Added "-E" option to all printing commands to force
1764 encryption.
1765 - The client code did not consume the response to the
1766 OPTIONS request when switching to secure mode.
1767 - The scheduler did not output a Content-Length field
1768 when responding to an OPTIONS request.
1769 - Added documentation on using cups-lpd with xinetd
1770 to the man page.
1771 - The socket backend now starts retries at 5 seconds and
1772 increases the interval to 30 seconds. This should
1773 provide faster printing when multiple jobs/files are
1774 queued for a printer.
1775 - The filters and backends no longer buffer output to
1776 stderr. This should provide much more accurate status
1777 reporting.
1778
1779
1780CHANGES IN CUPS V1.1.5-2
1781
1782 - Fixed configure check for OpenSSL to work with RSA
1783 code.
1784 - Added configure check for <sys/ioctl.h>, and use this
1785 check in backend/serial.c.
1786 - Updated configure script handling of data,
1787 configuration, and state directories to use datadir,
1788 sysconfdir, and localstatedir variables.
1789 - NetBSD uses different serial port filenames than
1790 FreeBSD and OpenBSD.
1791 - The pdftops filter didn't need some X-specific files.
1792 - The scheduler makefile doesn't do a chown anymore when
1793 installing (cupsd did this automatically on startup
1794 anyways)
1795
1796
1797CHANGES IN CUPS V1.1.5-1
1798
1799 - There was a typo in the top-level Makefile
1800 - The top-level Makefile did not install an init script
1801 for run level 5.
1802 - The configure script did not add the "crypto" library
1803 when checking for the OpenSSL library.
1804 - The OKIDATA PPD files were missing.
1805 - The config.h.in file defined the wrong version number.
1806 - The serial backend did not define "funky_hex" under *BSD.
1807 - Updated the Visual C++ project files and some of the
1808 CUPS API sources to compile under Windows again.
1809
1810
1811CHANGES IN CUPS V1.1.5
1812
1813 - Security updates - new default configuration does
1814 not broadcast printer information and only allows
1815 access from the local system.
1816 - EXPERIMENTAL encryption support - CUPS now optionally
1817 supports TLS/SSL encryption via the OpenSSL library.
1818 - Documentation updates.
1819 - Makefile/configure script updates.
1820 - The RPM spec file didn't work out-of-the-box under
1821 RedHat or Mandrake.
1822 - Minor code cleanup to remove extraneous compiler
1823 warnings.
1824 - cupsTempFile() was using %p for the temporary
1825 filename; this should have been %08x (just 8 digit
1826 hex)
1827 - Deleting a printer with active print jobs would still
1828 crash the server.
1829 - ippWrite() and ipp_write_file() didn't send the
1830 correct value length for name-with-language and
1831 text-with-language attributes.
1832 - Updated IPP code to support copied strings (that
1833 should not be freed); this provides slightly more
1834 efficient IPP server performance.
1835 - Updated PDF filter to Xpdf 0.91.
1836 - httpGets() could go into an infinite loop if a line
1837 longer than the input buffer size was sent by a
1838 client. This could be used in a Denial-of-Service
1839 attack.
1840 - The lpstat and CUPS API functions now request only the
1841 data required when getting the list of printer or
1842 class information. This should improve performance
1843 with large numbers of printers on slower machines.
1844 - The scheduler was always enforcing the FilterLimit,
1845 even if FilterLimit was set to 0.
1846 - Updated the Linux USB backend to support Mandrake's
1847 /dev/usb/usblp# filenames.
1848 - The PRINTER and LPDEST environment variables did not
1849 override the lpoptions default printer.
1850 - The PPD read functions incorrectly included trailing
1851 characters (usually whitespace) after quoted string
1852 attributes.
1853 - The multiple-document-handling attribute handling code
1854 did not check for the correct value for collated
1855 copies (separate-documents-uncollated-copies).
1856 - The EPSON driver did not work with OKIDATA printers in
1857 EPSON emulation mode (needed change-emulation command)
1858 - The HP-GL/2 filter did not scale the plot properly in
1859 scale mode 2.
1860 - Added PPD files for 9-pin and 24-pin OKIDATA printers.
1861 - The httpSeparate() function didn't handle passwords
1862 that started with a number.
1863 - ippDelete() could free the character set string
1864 multiple times in name-with-language and
1865 text-with-language attributes.
1866 - The scheduler would access freed memory right after
1867 freeing it (for debug messages); these parts of the
1868 code have been reordered to avoid this situation
1869 which was causing sporatic errors and crashes.
1870 - The ppdClose() function didn't free all of the strings
1871 in the ppd_file_t structure.
1872 - The LoadAllJobs() function in the scheduler did not
1873 close the spool directory.
1874 - Changed all sprintf's that use string formats to
1875 snprintf's, even if the destination buffer is
1876 larger than the source string(s); this protects
1877 against buffer overflows caused outside of CUPS...
1878 - Changed all strcpy's to strncpy's between local and
1879 global variables, even if the destination buffer is
1880 larger than the source string; this protects
1881 against buffer overflows caused outside of CUPS...
1882 - The CUPS certificate functions didn't use the
1883 CUPS_SERVERROOT environment variable when set.
1884 - The directory services code was copying instead of
1885 comparing the remote printer info, resulting in
1886 unnecessary updates of the printer attributes for
1887 remote printers.
1888 - Added new mime.types rules to allow automatic raw
1889 printing of PCL and ESC/P files; PJL headers are
1890 parsed to differentiate between PostScript and
1891 PCL job files. This should eliminate a lot of
1892 the reports of SAMBA printing problems due to
1893 the missing "-oraw" or "-l" options.
1894 - The mimeLoadType() function didn't handle the
1895 3-argument contains() function.
1896 - The LoadPPDs() function in the scheduler didn't
1897 properly set the alloc_ppds variable or handle a PPD
1898 database containing 0 printers.
1899 - The scheduler FindAvailablePrinter() function didn't
1900 use the same queuing logic as the CheckJobs()
1901 function. This caused classes to stall if a remote
1902 printer was always busy.
1903 - Jobs are now assigned to printers in a class
1904 round-robin style. This should prevent the first
1905 server in the class from bearing the brunt of the
1906 jobs.
1907 - The scheduler's LoadAllJobs() function didn't always
1908 restore remote printers for queued jobs on startup.
1909 - The serial backend didn't support the higher baud
1910 rates with the old termios interface. It now supports
1911 57600 and 115200 baud.
1912 - The serial backend now supports different types of
1913 flow control; previously it ignored the flow=XYZ
1914 option in the device URI.
1915 - The serial backend now supports DTR/DSR flow control,
1916 which is popular on dot-matrix printers (access with
1917 "flow=dtrdsr" in the device URI)
1918 - Added new job-originating-host-name attribute for
1919 jobs. The new attribute provides the hostname or
1920 IP address of the machine that submitted the job.
1921 - The set-job-attributes code no longer allows read-only
1922 job attributes to be changed.
1923 - Expanded the click area for the navigation bar in the
1924 web interface.
1925 - Updated the lp and cancel commands to support all of
1926 the Solaris print options (some are simply ignored
1927 since they do not map)
1928 - Updated the scheduler to limit the number of file
1929 descriptors to the maximum select() set size. This
1930 was causing problems on Solaris systems where the
1931 max FD count was increased beyond 1024.
1932 - The scheduler's LoadDevices() function was getting
1933 interrupted by the SIGCHLD signal handler; now ignore
1934 child signals while loading devices.
1935 - Added quota and allow/deny user support for printers
1936 and classes.
1937 - Removed black/CMY adjustment code from the PS and
1938 image file RIPs; it was interfering with some CUPS
1939 driver dithering code.
1940 - The lpc program stopped listing the queue statuses
1941 after the first active printer.
1942 - The cups-lpd program used an output format that the
1943 Solaris printing system did not understand.
1944 - Updated the lpq program to use the Solaris format
1945 except under Tru64 UNIX.
1946 - Some DEC PPD files incorrectly use "Off" for the null
1947 value in UI constraints. Added "Off" to the list of
1948 accepted null values.
1949 - Changed the *BSD define constants to __*BSD__ in all
1950 of the backends.
1951 - Added support for "lpstat printername", which is an
1952 undocumented feature in Solaris.
1953 - The HP-GL/2 filter now only sets the plot size if it
1954 is set in the plot file.
1955 - The lpmove command wasn't sending the requesting
1956 user name, causing it to always fail.
1957 - Updated the cupsTempFile() code to use GetTempPath()
1958 under Windows.
1959 - The cups-lpd mini-daemon didn't limit the number of
1960 data files accepted, didn't use cupsTempFile(),
1961 didn't handle control file job information in any
1962 order, and didn't free job options after printing
1963 a file.
1964 - The scheduler copy_banner() function did not
1965 explicitly set the owner and permissions of the banner
1966 files, which could prevent the banner pages from
1967 printing on some systems.
1968 - The lpstat program wasn't listing remote classes.
1969 - The scheduler did not verify that the printer-uri
1970 attribute was specified in all requests that required
1971 it.
1972
1973
1974CHANGES IN CUPS v1.1.4
1975
1976 - Makefile and configure script fixes.
1977 - **** Changed the default Printcap setting **** to
1978 /etc/printcap. There are just too many people asking
1979 why application XYZ doesn't see their printers!
1980 - The web admin interface now displays an error if it
1981 can't get the list of printer drivers from cupsd.
1982 - The IPP backend was putting the copies option before
1983 the other job options were set. This caused the IPP
1984 request to contain attribute groups in the wrong
1985 order, which prevented remote printing.
1986 - Added checks in scheduler to free memory used for
1987 IPP requests and language information when closing
1988 a client connection.
1989 - Fixed the duplex option in the HP LaserJet driver. It
1990 should now work with all LaserJet printers (and
1991 compatibles)
1992 - The add-printer web interface didn't initialize the
1993 "old info" data pointer, which caused random crashes
1994 on many OS's.
1995 - Fixed many page sizes defined in the Level 1
1996 compatibility file "gs_statd.ps" to match reality.
1997 - Fixed another bug in the setpagedevice "code" in
1998 Ghostscript. It should now accept all standard
1999 Adobe attributes on all platforms.
2000 - Fixed pstoraster so that it reallocates memory for
2001 color depth changes as well as size/resolution
2002 changes. This removes an ordering constraint on
2003 the color, page size, and resolution options in
2004 PPD files.
2005 - The IPP backend didn't use the job's character set
2006 when the destination printer supported it. This
2007 caused problems when printing text files to other
2008 CUPS servers.
2009 - Updated the logic used to determine when to rebuild
2010 the PPD file database. The scheduler now checks the
2011 dates and the number of PPD files (was just checking
2012 the dates.)
2013 - Updated the ippSetCGIVars() function (used by the
2014 web interfaces) to only filter valid string values.
2015 - The PostScript filter was scaling 2-up pages
2016 incorrectly. This caused the edges of some pages to
2017 be clipped.
2018
2019
2020CHANGES IN CUPS v1.1.3
2021
2022 - Makefile fixes.
2023 - RPM spec file changes.
2024 - Documentation updates.
2025 - Enabled pstoraster debug messages for everything
2026 (only logged when LogLevel set to "debug"...)
2027 - Changed the Input/OutputAttributes fix in
2028 pstoraster so that it works on all platforms.
2029 - The HP-GL/2 filter didn't set the right green
2030 color value in encoded polylines or text.
2031 - Updated the "fitplot" code to handle plot sizes
2032 specified as "PSwidth,length" and "PSlength,width".
2033 - Updated the Linux parallel and USB backends to open
2034 the device files prior to looking in /proc for
2035 autoprobe info. This makes sure that loadable device
2036 driver modules are in fact loaded...
2037 - Added new FilterLimit directive to limit the number
2038 of processing jobs/filters on a system.
2039 - set-job-attributes didn't change the job-state to
2040 held/pending when the job-hold-until attribute was
2041 specified.
2042 - set-job-attributes didn't save the new job attributes.
2043 - Now change the "requesting-user-name" attribute in
2044 requests from remote systems to "remroot" when an
2045 unauthenticated "root" user is sent. This can be
2046 changed using the new RemoteRoot directive in
2047 cupsd.conf.
2048 - The cancel-job, hold-job, release-job, and restart-job
2049 operations didn't log the authenticated username.
2050 - The cups-lpd mini-daemon now checks for a
2051 document-format option before forcing raw mode with
2052 filter mode 'l'.
2053 - The cups-lpd mini-daemon now supports "-o" options
2054 on the command-line (passed by inetd) to set global
2055 defaults for all print queues.
2056 - The pstops filter assumed that a file with a Trailer
2057 comment would also have an EOF comment.
2058 - Added new cupsSetPasswordCB(), cupsSetServer(),
2059 cupsSetUser(), and ippSetPort() functions to better
2060 support client applications (especially GUIs...)
2061 - The CUPS-add-class and CUPS-add-printer operations
2062 didn't reset the printer-name attribute on remote
2063 print queues that had to be renamed when a local
2064 printer was defined with the same name.
2065 - The lpoptions command now supports a "-r" option to
2066 remove options for a printer or instance.
2067 - The lpadmin and admin.cgi programs no longer allow
2068 class and printer names to begin with a number; this
2069 caused the command-line utilities to become confused.
2070 - The Linux USB backend now looks for both the parallel
2071 and usblp driver names in the device list.
2072 - Added a new FontPath directive to cupsd.conf, and also
2073 a "--with-fontpath" option for the configure script to
2074 specify alternate font paths for pstoraster.
2075 - The CUPS-move-job operation didn't update the
2076 job-printer-uri attribute.
2077 - The scheduler only looked up printers and classes by
2078 name in IPP requests, instead of using the full URI.
2079 This caused problems with KUPS and friends with
2080 remote printers.
2081 - The scheduler now handles better localization of
2082 hostnames (e.g. server is host.foo.com, remote is
2083 host.subfoo.foo.com, localized is not host.subfoo...)
2084 - The scheduler logging functions now use a common
2085 log file checking/rotation function (courtesy of
2086 Crutcher Dunnavant at Red Hat)
2087 - The scheduler could accept more client connections
2088 than it allocated for if more than one Port or Listen
2089 line was present in cupsd.conf.
2090 - Other minor scheduler performance tweeks.
2091 - The lpq and lprm commands didn't support the default
2092 printer set using lpoptions.
2093 - The lpoptions command now supports a "-l" option to
2094 list the printer-specific options and their current
2095 settings.
2096 - The web printer and class lists now show a link to the
2097 default printer or class at the top of the page.
2098 - The text filter now supports pretty printing of shell
2099 and perl scripts as well as C/C++ source files.
2100 - The top and bottom margins were reversed for landscape
2101 text printing.
2102 - The lpq and lprm commands didn't understand printer
2103 instances.
2104 - The scheduler only selected on the first 100 file
2105 descriptors instead of the maximum file descriptor
2106 limit.
2107 - The scheduler client, listener, and mainline functions
2108 now share code to disable and enable monitoring for
2109 new client connections.
2110 - The imagetoraster filter didn't support all of the
2111 required pagedevice parameters.
2112 - The serial backend now checks for 100 serial ports
2113 under Linux.
2114 - The scheduler used sscanf() to pull out the remote
2115 printer location, description, and make/model strings,
2116 but if any of these options was empty then sscanf()
2117 would stop processing.
2118 - Added "debug2" log level to provide a little less
2119 verbose debugging information at the "debug" level.
2120 - The scheduler would crash if you stopped a printer
2121 that was currently printing a job.
2122 - The scheduler incorrectly allowed jobs in the cancelled,
2123 aborted, or completed state to be cancelled.
2124 - The image filters did not load TIFF images properly
2125 for bottom-to-top and right-to-left orientations.
2126 - Added new cupsEncodeOptions() function to encode
2127 CUPS options as IPP job attributes.
2128 - The IPP backend, LPD mini-daemon, client commands,
2129 and CUPS API did not properly encode multiple
2130 option values separated by commas.
2131 - Added new scheduler malloc logging in debug mode
2132 (provides summary of total arena size, allocated,
2133 and free bytes once a minute)
2134 - The EPM-based distributions didn't install the
2135 correct symlinks for a few man pages.
2136 - Fixed a memory leak in the scheduler - wasn't
2137 freeing old filters when deleting or renaming
2138 printers.
2139 - The scheduler now queries the primary IP address
2140 for the name of the server and maps any incoming
2141 requests from that address to the server name.
2142 This fixes web admin mapping problems from
2143 server.domain.com to localhost.
2144 - The web printer modify interface now remembers
2145 the previous device and driver settings (except
2146 for serial ports.)
2147 - The job-k-octets attribute is now stored as part of
2148 the job attributes; this preserves the information
2149 after a job is completed when job file history is
2150 turned off.
2151 - Dropped option sub-group parsing code for the moment,
2152 since many Xerox PPD files abuse this feature in PPD
2153 files and don't follow the hierarchy rules.
2154 - Added new wrapper code around options so that duplex
2155 options for some HP printers don't prevent prints.
2156 - Added support for Digital UNIX/Tru64 UNIX/OSF/1 format
2157 for "lpstat -v" output.
2158 - Now show the URI for remote printers instead of
2159 /dev/null in "lpstat -v" output.
2160 - Creating classes and adding printers to a class with
2161 the lpadmin command didn't work.
2162 - The banner pages and test page should now format
2163 correctly in both portrait and landscape orientations.
2164 - Updated banner page substitution so that { can appear
2165 by itself without quoting.
2166
2167
2168CHANGES IN CUPS v1.1.2
2169
2170 - Makefile/configure fixes
2171 - RPM spec file and EPM list file fixes
2172 - The cupsTempFile() function now uses a different
2173 algorithm for generating temp files and "reserves"
2174 them to avoid possible security exploitation.
2175 - Now use /dev/random (if available) to seed the random
2176 number generator for certificates.
2177 - The /var/spool/cups and /var/spool/cups/tmp directories
2178 were incorrectly owned by root; they are now owned by
2179 the filter user, typically "lp".
2180 - The scheduler now resets the permissions on the spool
2181 and temp directories as needed to match the filter
2182 user.
2183 - Now expose ppdCollect() as an externally callable
2184 function.
2185 - The image filters now support filtering from the
2186 standard input.
2187 - The imagetoraster filter now collects all printer
2188 options and job patch files and applies them to the
2189 page header as needed.
2190 - Added format and banner options to LPD backend.
2191 - The send-document operation didn't start a job
2192 immediately when last-document was true.
2193 - The set-job-attributes operation didn't correctly
2194 replace the current job-hold-until value.
2195 - Removed the option wrapper code from ppdEmit() and
2196 friends since it caused problems with Ghostscript
2197 and many PS printers.
2198 - Was setting TZ environment variable twice for job
2199 filters.
2200 - Added syslog logging in cups-lpd to aide in
2201 debugging problems.
2202 - The HP-UX parallel port backend did not list the
2203 available parallel ports on some systems (printf
2204 calling problem...)
2205 - The lp and lpr commands overrode user options if
2206 -d/-P were specified after -o.
2207 - The scheduler would crash with a */* filter.
2208 - Added support for a "default" filter for unknown file
2209 types. The example provided in the mime.types and
2210 mime.convs file prints unknown files as if "-oraw" was
2211 specified for the job. This functionality is disabled
2212 by default.
2213 - The "compatibility" mode fix for older backends did not
2214 work for smbspool. Added a workaround for it.
2215 - The HP-GL/2 filter didn't perform the right pen scaling
2216 with some files and the "fitplot" option.
2217 - New Software Performance Specification document that
2218 describes the memory, disk, and CPU usage of all the
2219 CUPS software.
2220
2221
2222CHANGES IN CUPS v1.1.1
2223
2224 - The pstoraster Makefile still referenced one of the
2225 old PDF filter files.
2226 - The filter Makefile used INSTALL_DATA instead of
2227 INSTALL_LIB to install the CUPS image library.
2228 - The administration CGI didn't work properly with
2229 network devices.
2230 - The BrowseACL variable was not updated after the
2231 cupsd.conf file was loaded.
2232 - The lpd mini-daemon didn't support printer instances.
2233 - Now use a default umask of 077 for child processes.
2234 - Now put temp files in /var/spool/cups/tmp for child
2235 processes and the root user, unless TMPDIR or TempDir
2236 is defined otherwise.
2237 - cupsGetPPD() no longer uses easy-to-guess filenames.
2238 - The CUPS-Delete-Class and CUPS-Delete-Printer
2239 operations now save classes.conf file as needed.
2240 - The lppasswd command wouldn't add a user.
2241 - The ppdOpen() function could cause a segfault if a
2242 0-length PPD file was read.
2243 - The image filters were not handling images with
2244 different X and Y resolutions properly.
2245 - The imagetoraster filter defaulted to RGB output
2246 instead of black output like pstoraster.
2247 - The pstops filter didn't handle binary data properly.
2248 - The pstops filter didn't handle copies properly for
2249 PS files lacking DSC comments.
2250 - The pstops filter now appends %%EOF to the end of
2251 documents if they don't have it.
2252 - The cupsGetPPD() function didn't work with remote
2253 printers lacking the @server in the name.
2254 - The configure script didn't work right when only
2255 --prefix was specified.
2256 - The ppdEmit() code now wraps all printer commands so
2257 that buggy PostScript printers will still print a file
2258 after receiving an option that isn't available.
2259 - Fixed the DeskJet margin bug, and disabled 600dpi
2260 color mode until it can be fixed.
2261 - The cupsAddDest() function didn't sort instances
2262 correctly in all cases.
2263 - The time-at-xyz attributes now expand to the date and
2264 time in banner files.
2265
2266
2267CHANGES IN CUPS v1.1
2268
2269 - Documentation updates.
2270 - Configuration script updates.
2271 - Didn't map charset and language value strings to lowercase
2272 and _ to - as required by SLP and IPP.
2273 - ppdLoadXYZ() didn't add the list of available fonts to the
2274 ppd_file_t structure.
2275 - The text filter common code was freeing the PPD file data
2276 before it was used.
2277 - The text filter now embeds missing fonts.
2278 - The CGI interface now maps local access to the server to
2279 the localhost address.
2280 - The HP-GL/2 filter didn't use the specified (or default)
2281 color ranges, resulting in strange colors.
2282 - The HP-GL/2 filter didn't default to no input window, which
2283 caused unnecessary clipping of plots.
2284 - Integrated Xpdf's pdftops filter into CUPS, which is a
2285 lightweight and reliable replacement for Ghostscript's
2286 PDF support.
2287 - Removed all PDF support from Ghostscript.
2288 - Updated HP driver to set top margin; this seems to fix
2289 the offset problem seen on HP DeskJet printers.
2290 - Fixed dependencies on the ZLIB and JPEG libraries in
2291 pstoraster.
2292 - The lpr command wasn't using the lpoptions defined by
2293 the user.
2294 - The lpr command would segfault if the CUPS server was
2295 not running.
2296 - The top-level makefile was not installing the CUPS
2297 initialization script. It now does so if it sees there
2298 is an init.d directory in /sbin, /etc/rc.d, or /etc.
2299 - "lpstat -v all" didn't work.
2300 - pstoraster would crash on some platforms doing the
2301 setpagedevice operator.
2302 - The web administration interface now allows you to set
2303 the default banner pages.
2304 - Images can now be positioned on the page using the new
2305 "position" option.
2306 - The AccessLog, ErrorLog, and PageLog directives now
2307 support "%s" to insert the server name.
2308 - Added a new BrowseShortNames directive to allow for
2309 short remote printer names ("printer" instead of
2310 "printer@server") when possible.
2311 - The scheduler could crash if given an invalid PPD file
2312 with no PageSize attributes.
2313 - Updated the serial, parallel, and usb backends to do
2314 multiple writes and ignore ioctl() errors as needed;
2315 this should fix problems with serial printing on old
2316 serial drivers and with the UltraSPARC parallel port
2317 driver under Solaris 2.7.
2318 - Now propagate LD_LIBRARY_PATH to child processes from
2319 cupsd.
2320 - New DataDir directive for installing in alternate
2321 locations.
2322 - New CUPS_SERVERROOT and CUPS_DATADIR environment
2323 variables to specify installation directories as
2324 needed.
2325 - Queued remote jobs recreate remote printers as needed
2326 when the scheduler is started.
2327 - Deleting a printer also purges all jobs on that
2328 printer.
2329 - Old job and control files that don't belong to a
2330 printer are automatically deleted.
2331 - Wasn't updating time-at-processing and
2332 time-at-completed attributes in job.
2333 - Didn't send required multiple-operation-time-out
2334 attribute in response to a get-printer-attributes
2335 request.
2336 - cups-lpd now supports options set with lpoptions.
2337 - The job-hold-until attribute is now provided with all
2338 jobs. For jobs that are not currently held the value
2339 is "no-hold".
2340 - The scheduler was not sending "unknown" values in IPP
2341 responses.
2342 - The lpoptions command now accumulates options from
2343 previous runs rather than replacing all options for a
2344 printer.
2345 - The IPP backend now switches to IPP/1.0 if a 1.1
2346 request fails.
2347 - The lpadmin and admin.cgi programs now validate new
2348 printer and class names.
2349 - The access_log file now includes the number of IPP bytes
2350 received in a POST request.
2351
2352
2353CHANGES IN CUPS v1.1b5
2354
2355 - Documentation updates.
2356 - The pstoraster filter didn't compile without the JPEG library.
2357 - The cupsd server didn't support the HTTP OPTIONS request
2358 method.
2359 - Dropped the "CLOSE" method supported by the cupsd server.
2360 (not defined in HTTP specification)
2361 - Makefile/configure script fixes.
2362 - Missing the job-restart template.
2363 - Added IPP test suite for testing.
2364 - Missing IPP documentation from binary distributions.
2365 - Fixed multiple-document handling code when last-document
2366 not specified.
2367 - Added more checks to IPP requests to prevent bad requests
2368 from getting through.
2369 - Not all of the Ghostscript error output was being sent to
2370 stderr.
2371 - The PostScript filter now added PJL commands to set the
2372 job name and display string, if supported.
2373 - The scheduler would crash if the browse socket could not
2374 be bound. Now disables browsing if port 631 (reserved for
2375 IPP) is being used by a misbehaving daemon.
2376 - The USB backend now looks for the older Linux 2.2.x USB
2377 printer device filenames as well as the newer ones.
2378 - The IPP backend now uses the UTF-8 charset exclusively,
2379 since apparently only CUPS handles more than US-ASCII and
2380 UTF-8...
2381 - Wasn't quoting ( in PostScript banners...
2382 - Send-document requests with no document-format attribute
2383 could cause cupsd to crash.
2384 - Old jobs in the spool directory might cause cupsd to
2385 crash.
2386 - CUPS now supports all of the recommended job-hold-until
2387 keywords as well as name values of the form "HH:MM" and
2388 "HH:MM:SS".
2389 - Added placeholder pointer for TLS encryption to the HTTP
2390 connection structure.
2391 - Fixed the "fast poll" bug reported by DISA - the
2392 status pipe wasn't being closed for multi-file jobs.
2393 - Revamped put_params code in pstoraster to fix bitmap
2394 allocation bug with FrameMaker output.
2395 - Ripped out filename, etc. code from pstoraster as it
2396 is a potential security hole.
2397 - Added support for RIP_CACHE environment variable in the
2398 new pstoraster.
2399 - Fixed USB device filenames for Linux; now support new
2400 pre-2.4 devices (/dev/usb/lp#) and 2.2 devices
2401 (/dev/usblp#)
2402 - Fixed accept-jobs crash with classes.
2403 - Didn't include dot-matrix EPSON drivers in previous
2404 release.
2405
2406
2407CHANGES IN CUPS v1.1b4
2408
2409 - Documentation updates.
2410 - Many makefile and configuration script fixes (should
2411 now compile better under *BSD.)
2412 - The MediaPosition attribute was being mishandled by
2413 GhostScript, causing the RIP to fail whenever a paper
2414 tray was selected.
2415 - The scheduler now logs the final line of log information
2416 from a filter, even if it doesn't end with a newline; this
2417 primarily affects GhostScript error output.
2418 - The scheduler was saving implicit classes, so after a few
2419 restarts you'll end up with AnyPrinter, AnyAnyPrinter, etc.
2420 - The JPEG autodetection didn't work with some JPEG files that
2421 came from digital cameras (JPEG but not JFIF); the new
2422 magic types should work with all images that the JPEG library
2423 can handle.
2424 - Fixed a bug in the new contains() MIME type rule that could
2425 cause cupsd to crash.
2426 - Switched to using strtol() in the MIME type code so that you
2427 can use hex, octal, or decimal constants as desired in the
2428 mime.types file.
2429 - Banner files are now treated as templates, allowing any type
2430 of file to be used as a banner.
2431 - Added a 30-second timeout to backend device reports so that a
2432 hung backend will not prevent the scheduler from starting.
2433 - Backends are once again terminated when jobs are stopped; the
2434 CUPS-supplied backends will stay alive until the downstream
2435 filters have had a chance to clear out old page data.
2436 - The charset lookup in the CUPS localization support was wrong
2437 (iso8859-x instead of iso-8859-x)

2445 code.
2446 - Added Solaris options to System V commands.
2447 - Now support the output-bin job template attribute.
2448 - Now log the job-billing attribute in the page_log file, and
2449 keep track of the total number of pages in the
2450 job-media-sheets-completed attribute.
2451 - The penwidth option is now in micrometers to support more
2452 accurate width specification.
2453 - The image filters now support interlaced and transparent PNG
2454 files.
2455 - Didn't handle Keep-Alive for HTTP/1.0 clients.
2456 - The BrowsePoll support didn't handle when BrowseInterval
2457 was set to 0 (now uses 30 seconds if BrowseInterval is 0)

2471
2472CHANGES IN CUPS v1.1b3
2473
2474 - Documentation updates.
2475 - The startup script redirected stderr before stdout,
2476 which caused problems with some versions of Bourne
2477 shell and Bash.
2478 - Fixed a bug in the scheduler's PPD language reading
2479 code.
2480 - Fixed a bug in the scheduler's check for the
2481 manufacturer in the PPD.
2482 - The pstoraster filter didn't allow some input and
2483 output attributes to be set.
2484 - Added banner page support.
2485 - Added missing PAM configuration file.
2486 - Configuration script fixes for Linux and *BSD.
2487 - The log file code was using the wrong sign for the
2488 timezone offset.

2490 file is generated).
2491 - The scheduler did not start jobs destined for remote
2492 printers when they became available.
2493 - The scheduler now sends jobs to remote printers
2494 immediately. (when sending jobs to a class, the remote
2495 printer is only used when it becomes available)
2496 - The scheduler now supports printing of banner pages
2497 via the job-sheets attribute (banner files go in
2498 /usr/share/cups/banners)
2499 - The cupsd process now forks itself into the background
2500 (override with -f)
2501 - Added several *BSD enhancements.
2502 - Added UNSUPPORTED libtool option to configuration
2503 script to allow the use of libtool. Note that this is
2504 UNSUPPORTED by us, but added by request of the *BSD
2505 folks.
2506 - The parallel, serial, and usb backends now retry the
2507 opening of their ports. This allows multiple print
2508 queues to be associated with a single physical port,
2509 and will allow CUPS to support several types of
2510 parallel port auto-switches in the near future.
2511 - Set-Job-Attributes now supports adding, changing, and
2512 deleting job template attributes, and no longer allows
2513 job-printer-uri to be set (see CUPS-Move-Job)
2514 - Added CUPS-Move-Job operation to support moving of jobs.
2515 - The CGI template functionality now supports multiple
2516 languages (still only have templates for English)
2517 - The CUPS-Get-Printers and CUPS-Get-Classes operations
2518 now support filtering as defined in the IDD.
2519 - The Get-Jobs, CUPS-Get-Printers, and CUPS-Get-Classes
2520 operations no longer limit themselves to 1000 jobs,
2521 printers, or classes (believe it or not, this is
2522 needed for some sites)
2523 - The web interfaces now support language-specific
2524 templates.
2525 - The web admin interface now supports class management.
2526 - The web admin interface now shows a list of
2527 manufacturers before selecting the PPD/driver for a
2528 specific printer.
2529 - The web admin interface now supports configuration of
2530 the default printer options in the PPD file.
2531 - The web interface now uses printer/class
2532 authentication for the test page instead of admin
2533 authentication.
2534 - Updated the RPM spec file for the current release.
2535 - Updated language support for Windows code pages.
2536 - 8-bit character set files can now use multiple fonts
2537 (needed for Arabic, Greek, Hebrew, etc.)
2538 - Added basic right-to-left text support in the text
2539 filter.
2540 - The POSIX locale now uses ISO-8859-1 instead of
2541 US-ASCII.
2542 - Fixed PDF printing problems.
2543 - Fixed PostScript RIP page device dictionary elements
2544 that weren't getting passed in cups_get_params().
2545 - Added a new "contains" rule for the magic file typing.
2546 - The "printable" rule now accepts characters from 128 to 255
2547 (needed for Microsoft character sets)
2548 - Added support for ~/.cupsrc as well as /etc/cups/client.conf
2549 so that the default server can be configured on a per-user
2550 basis without environment variables.
2551 - Added LPD mini-daemon to support incoming LPD jobs.
2552
2553
2554CHANGES IN CUPS v1.1b2
2555
2556 - Documentation updates.
2557 - The lp command didn't always load the user-defined
2558 destinations, preventing it from seeing the default
2559 printer.
2560 - Many configure script and makefile fixes.
2561 - The Microsoft code page files were missing from the
2562 distribution.
2563 - Added a workaround for the HP IPP client (which is sending
2564 an invalid printer-uri in requests)
2565 - Fixed the encoding of text-with-language and name-with-language
2566 to match the IPP spec.

2576 - Added BrowseAllow, BrowseDeny, BrowseOrder, BrowsePoll, and
2577 BrowseRelay directives.
2578 - BrowseInterval 0 disables advertising of local printers, but
2579 still receives information on remote printers.
2580 - New browse polling daemon (for polling servers on different
2581 networks)
2582 - New PPD cache file for faster startup times with large numbers
2583 of PPD files.
2584 - The Host: field was incorrectly required for HTTP/1.0 clients.
2585 - New set-job-attributes operation now supported.
2586 - The mime_load_types() and mime_load_convs() functions did not
2587 close their input files.
