8 | Version 2.3.2 |
9 | ||
f87277f2 RM |
10 | * Thread-safe interfaces for many functions that access locale data |
11 | were added in version 2.3, but these features were omitted from NEWS. | |
12 | Many functions have variants with an `_l' suffix that take a `locale_t' | |
13 | object as a parameter rather than consulting the current locale. | |
14 | The new functions `newlocale', `duplocale', and `freelocale' in <locale.h> | |
15 | create and maintain `locale_t' objects. Additionally, the new function | |
16 | `uselocale' sets "the current locale" (as used by functions not so | |
17 | parameterized) set for an individual thread. These features were added | |
18 | in version 2.3, implemented by Ulrich Drepper and Roland McGrath. | |
19 | ||
747bf98e RM |
20 | * The functions getresuid, getresgid, setresuid, and setresgid, which |
21 | have long been available on Linux, are now declared in <unistd.h> | |
22 | and are now also available on the Hurd. | |
23 | ||
24 | * ELF thread-local storage support (TLS) now works on x86-64. | |
d62507dd RM |
25 | |
26 | * The new dynamic string token $LIB is expanded in shared library names. | |
27 | This normally expands to lib, but on some 64-bit platforms to lib64 instead. | |
52a16e58 | 28 | |
f87277f2 RM |
29 | * Aldy Hernandez contributed complete software floating point support for |
30 | PowerPC machines with no FPU. | |
31 | ||
52a16e58 | 32 | * fexecve is implemented on Linux. |
f9ad060c | 33 | |
f87277f2 RM |
34 | * The `btowc' function should work at least twice as fast due to |
35 | specialized callbacks in the iconv modules. Implemented by Bruno Haible. | |
9ef0a840 UD |
36 | |
37 | * With approriate thread add-ons cancelable functions are now implemented | |
38 | in libc.so as well. No need to call the function in libpthread. This | |
39 | change allowed to finally disable the incorrect and expensive handling | |
40 | of weak definition in ld.so. | |
41 | ||
42 | * Yet more PLT entries in libc.so have been removed. We finally arrived | |
43 | at the bare minimum. Startup times improved appropriately. | |
44 | ||
45 | * Support for the new Linux/x86 system call interface was added. The | |
46 | AT_SYSINFO auxiliary vector entry is recognized and handled. | |
747bf98e | 47 | \f |
03a2c647 | 48 | Version 2.3 |
37fb1084 | 49 | |
03a2c647 UD |
50 | * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164 |
51 | charsets. | |
52 | ||
53 | * iconv (the program and the interface) now accepts empty names (excluding | |
54 | options like //TRANSLIT) to mean "use charset of current locale". | |
47e8b443 | 55 | |
bb0ec5bd | 56 | * localedef can now transliterate characters in strings which are not in |
47e8b443 | 57 | the provided charmap. The information from the input locale is used. |
c17f665b UD |
58 | |
59 | * Prelinking support was added for ELF targets. This requires additional | |
60 | tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek. | |
8e57fc70 | 61 | |
bb0ec5bd | 62 | * Read-only stdio streams now use mmap to speed up operation by eliminating |
91e6367e UD |
63 | copying and buffer underflows. To use add 'm' to the mode string of |
64 | the fopen/fdopen/freopen call. Implemented by Ulrich Drepper. | |
207b66ce UD |
65 | |
66 | * The malloc functions were completely rewritten by Wolfram Gloger based | |
67 | on Doug Lea's malloc-2.7.0.c. | |
3b0bdc72 | 68 | |
bb0ec5bd | 69 | * Isamu Hasegawa contributed a completely new and POSIX-conformant |
3b0bdc72 | 70 | implementation of regex. |
02779eaa UD |
71 | |
72 | * Bruno Haible upgraded the iconv and locale implementation to support | |
73 | Unicode 3.2. | |
be45f421 | 74 | |
bb0ec5bd RM |
75 | * Contents of the LC_* and LANG environment variables in the CEN style are |
76 | not recognized anymore. It never was used. Change by Ulrich Drepper. | |
be45f421 | 77 | |
bb0ec5bd RM |
78 | * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF |
79 | thread-local storage (TLS) ABI on some platforms. | |
80 | Changes by Ulrich Drepper. SH support by Kaz Kojima. | |
be45f421 UD |
81 | |
82 | * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213, | |
f87277f2 | 83 | EUC-JISX0213, and TSCII. |
a753ffb2 RM |
84 | |
85 | * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs': | |
86 | BSD-compatible interface for getting all network interface addresses. | |
87 | Implementation for IPv4 by Roland McGrath. | |
6a9340b5 UD |
88 | |
89 | * Loading of locale data is faster due to the introduction of a locale | |
90 | archive. Implemented by Roland McGrath and Ulrich Drepper. | |
dd4f2115 UD |
91 | |
92 | * Startup times are significantly reduced by not using exported functions | |
93 | inside the library itself. Changes by Jakub Jelinek, Roland McGrath, | |
94 | and Ulrich Drepper. | |
c843e065 RM |
95 | |
96 | * Steven Munroe contributed a port to PowerPC64/Linux. | |
97 | \f | |
45061a15 RM |
98 | Version 2.2.6 |
99 | ||
100 | * The Hurd now uses the GNU libio implementation of stdio rather than the | |
101 | old GNU stdio implementation, and uses a new ABI (libc.so.0.3). | |
102 | ||
103 | * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file | |
104 | with the same behavior as the Linux system call of the same name. | |
03a2c647 | 105 | \f |
a8ae31c2 UD |
106 | Version 2.2.5 |
107 | ||
76321a25 AJ |
108 | * Stephen Moshier implemented log2, log10, powl and cbrtl for the |
109 | 128-bit long double format. | |
a8ae31c2 | 110 | |
557a9213 UD |
111 | * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160, |
112 | IBM1161, and IBM1162 charsets. | |
a8ae31c2 | 113 | |
ad2e4f18 | 114 | * Andreas Jaeger contributed a port to x86-64/Linux. |
a8ae31c2 | 115 | |

116 | * Peter Bruin contributed a port to PowerPC/Hurd. |
117 | ||
a8ae31c2 UD |
118 | * libc functions using I/O streams now can handle wide-oriented streams |
119 | as well. | |
120 | ||
45061a15 RM |
121 | * optimizations in the dynamic linker. Binaries created by recent binutils |
122 | versions start up quicker due to reduced time spent on relocations. | |
8e57fc70 UD |
123 | |
124 | * Support for use of gcc3 added by Jakub Jelinek and HJ Lu. | |
7d0c5823 | 125 | \f |
33996419 AJ |
126 | Version 2.2.4 |
127 | ||
2995f70e | 128 | * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, |
aff17a50 | 129 | asinh, atanh, j0 for the 128-bit long double format. |
8fee1bb0 UD |
130 | |
131 | * Bruno Haible updated all the code handling Unicode in some form to | |
132 | support Unicode 3.1. | |
86dbe05e UD |
133 | |
134 | * Speed of regex for single-byte locales is back to previous levels. | |
135 | Patch by Isamu Hasegawa. | |
045fcd26 | 136 | |
69d5f925 | 137 | * Alpha, SPARC, and IA-64 now also using floating stacks. |
045fcd26 | 138 | |
69d5f925 | 139 | * Startup time of internationalized applications greatly improved through |
045fcd26 UD |
140 | iconv cache. Use iconvconfig to generate the cache file. |
141 | Contributed by Ulrich Drepper. | |
142 | ||
143 | * The IA-64 specific part of ld.so was rewritten to eliminate some pretty | |
144 | severe performance problems. Patch by David Mosberger. | |
145 | ||
146 | * The Hurd port got a lot more functionality like AIO, various stdio | |
147 | extensions, etc. Mainly done by Roland McGrath. | |
129d706d UD |
148 | |
149 | * mtrace can now lookup symbols in shared libraries. | |
33996419 | 150 | \f |
2ace5721 UD |
151 | Version 2.2.3 |
152 | ||
1746f2b0 | 153 | * Intel's IA-64 math library is largely integrated. It provides fast and |
2ace5721 UD |
154 | accurate implementatations for most basic and standard math functions |
155 | in float, double, and long double format. | |
156 | ||
f128331c | 157 | * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, |
b8750342 UD |
158 | and asin for the 96-bit long double format and asin, log, tan for the |
159 | 128-bit long double format. | |
07f951e4 | 160 | |
e4d82761 UD |
161 | * The beginning of a last-bit accurate math library by IBM Haifa were added. |
162 | The basic double functions exist today. Contributed by Abraham Ziv | |
163 | <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis | |
164 | <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. | |
165 | ||
2ace5721 UD |
166 | * An asynchronous name lookup library was added. The interface is designed |
167 | after POSIX AIO. The proposal was circulated beforehand to get comments. | |
168 | No negative ones came in. Implemented by Ulrich Drepper. | |
b8a8413c UD |
169 | |
170 | * Port to S390/64bit contributed by Martin Schwidefsky | |
171 | <schwidefsky@de.ibm.com>. | |
a66f0958 UD |
172 | |
173 | * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family | |
174 | of functions for Linux/IA-64. | |
481b550f UD |
175 | |
176 | * The RPC code is now thread safe. Threads can now use the same service | |
177 | of different services at the same time. Patch by Eric Norum | |
178 | <eric.norum@usask.ca> with some help by Ulrich Drepper. | |
f128331c UD |
179 | |
180 | * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext | |
181 | family of functions for Linux/S390. | |
232fdf8c UD |
182 | |
183 | * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family | |
184 | of functions for Linux/x86. | |
eacde9d0 UD |
185 | |
186 | * Port to Linux/CRIS contributed by Axis Communications. | |
2ace5721 | 187 | \f |
306eeae5 UD |
188 | Version 2.2.2 |
189 | ||
464d97ec | 190 | * Lots of headers were cleaned up. Using the tool in the conform/ subdir |
306eeae5 UD |
191 | we can now check for namespace violations and missing declarations. The |
192 | result is that almost all headers are now Unix-compliant (as defined in | |
193 | the upcoming XPG6). The negative side is that some programs might need | |
194 | corrections, too, if they depend on the incorrect form of the headers in | |
195 | previous versions which defined too many symbols and included too many | |
196 | other headers. | |
464d97ec UD |
197 | |
198 | * regex now handles multibyte character sets correctly. | |
199 | Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. | |
200 | ||
201 | * iconv (the program) does now conform to the upcoming XPG6 and handles | |
202 | charmaps. Instead of the charset names the path of charmaps can be | |
203 | provided and the conversion happens based on this data. | |
204 | Contributed by Ulrich Drepper. | |
205 | ||
206 | * The locale program now provides detailed information about the installed | |
207 | locales. While | |
208 | ||
209 | locale -a | |
210 | ||
211 | only lists the names of the supported locales | |
212 | ||
213 | locale -a --verbose | |
214 | ||
215 | provides details such as country, language, and codeset name. | |
216 | Contributed by Ulrich Drepper. | |
306eeae5 | 217 | \f |
d2defdc4 UD |
218 | Version 2.2.1 |
219 | ||
220 | * The gencat program now parses the input file according to the charset | |
221 | selected by the LC_CTYPE category. This is important for stateful | |
222 | character sets. To make generating catalogs easier there is a way | |
223 | to overwrite the charset selected by the locale: before the first | |
224 | message or $ quote line the catalog can contain a line like | |
225 | ||
226 | $ codeset=ISO-8859-2 | |
227 | ||
228 | to select the charset (ISO-8859-2 in this case). | |
229 | ||
230 | Implemented by Shinya Hanataka and Ulrich Drepper. | |
aea6353a UD |
231 | |
232 | * New codeset conversion modules: IBM-922 (Estonia PC codeset), | |
233 | IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). | |
234 | Contributed by Masahide Washizawa <washi@jp.ibm.com>. | |
234669e2 UD |
235 | |
236 | * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson | |
237 | <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. | |
238 | ||
239 | * The LANGUAGE environment variable is now ignored unless the locale is | |
240 | changed from the default "C" locale. | |
241 | ||
242 | * The usual bug fixes. | |
d2defdc4 | 243 | \f |
2e92188d UD |
244 | Version 2.2 |
245 | ||
08a2e4a0 GM |
246 | * Greg McGary added runtime support for bounds checking using gcc's |
247 | new -fbounded-pointers option. ix86 target is complete. PowerPC | |
248 | is in progress. | |
249 | ||
2e92188d UD |
250 | * Thorsten Kukuk added secure mode support to nscd. |
251 | ||
793bd4d9 | 252 | * The Berkeley db libraries have been removed. |
2e92188d | 253 | |
47b853e8 UD |
254 | Related, the nss_db module is now in a separate package since it |
255 | obviously requires a database library being available. | |
256 | ||
0013b2b1 UD |
257 | * Wide character I/O streams implemented by Ulrich Drepper. |
258 | ||
abbffdf9 | 259 | * Functions from the extended socket API added by Ulrich Drepper. |
01c771d0 | 260 | |
6e8afc1c UD |
261 | * Functions feenableexcept and fedisableexcept to control the |
262 | behaviour of individual exceptions have been added by Andreas Jaeger. | |
263 | ||
591e1ffb UD |
264 | * ldconfig program added by Andreas Jaeger and Jakub Jelinek. |
265 | ||
d3436b3c UD |
266 | * The resolver code has been updated from bind 8.2.3-T5B which supports |
267 | threads. The integration was done by Andreas Jaeger, Adam D. Bradley, | |
268 | and Mark Kettenis. | |
2588068b UD |
269 | |
270 | This change could in some situations effect backward compatibility. Since | |
271 | now `_res' is a thread-local instead of a global variable, modifying it | |
272 | in one thread does not have any effect in other threads. | |
66ac0abe | 273 | |
a00c3ca9 | 274 | The resolver library was also extended to allow IPv6 as the transport |
d3436b3c UD |
275 | protocol for the requests. This work was done by Stig Venaas. |
276 | ||
1c5d4617 UD |
277 | * Compatibility code for K&R C compilers has been removed from the |
278 | header files. A ISO C compiler is needed to use the library | |
279 | (conforming to either C89 or C99 standard). | |
280 | ||
abbffdf9 UD |
281 | * Complete rewrite of the localedef program to support multibyte character |
282 | sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, | |
283 | strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. | |
284 | Implemented by Ulrich Drepper. | |
285 | ||
8f3f1e09 UD |
286 | Bruno Haible significantly improved the generation and use of the data |
287 | structures for the wide character tables. | |
288 | ||
abbffdf9 UD |
289 | * Plural handling in gettext implemented by Ulrich Drepper. |
290 | ||
69173865 UD |
291 | * The utmp daemon has been removed. |
292 | ||
293 | * The port to MIPS-Linux has been finished by Andreas Jaeger. | |
294 | ||
37fb8add UD |
295 | * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima |
296 | and Yutaka Niibe. | |
297 | ||
594cee6c UD |
298 | * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. |
299 | ||
40c4c9b5 UD |
300 | * POSIX barriers implemented by Kaz Kylheku. |
301 | ||
594cee6c UD |
302 | * POSIX spawn function family implemented by Ulrich Drepper. |
303 | ||
304 | * POSIX spinlocks are now available. | |
305 | ||
40c4c9b5 UD |
306 | * Timed wait functions for mutex, rwlock, and semaphores are implemented. |
307 | ||
8f3f1e09 UD |
308 | * the configure option --enable-kernel=X.Y.Z allows to strip out |
309 | compatibility for kernel versions before X.Y.Z. This is currently only | |
310 | implemented for Linux. | |
311 | ||
3107c0c5 UD |
312 | * the sockaddr_in6 structure changed. The IPv6 working group added a new |
313 | field sin6_scope_id. This means that all programs using IPv6 should be | |
314 | recompiled. Don't expect binary compatibility with previous glibc | |
315 | versions. | |
316 | ||
d2830ba4 UD |
317 | * various conversion modules for IBM character sets contributed by |
318 | Masahide Washizawa. | |
319 | ||
8f3f1e09 UD |
320 | * IA-64 port by Jes Sorensen and HJ Lu. |

323 | Compiling the GNU C Library for Linux/ia64 | |
324 | ****************************************** | |
325 | ||
326 | Please refer to the file INSTALL in the same directory as you found | |
327 | this file for general information about configuring and compiling | |
328 | glibc. | |
329 | ||
330 | For general inquiries about glibc under Linux/ia64 please use the | |
331 | following mailing list linux-ia64@linuxia64.org or one of the relevant | |
332 | glibc mailing lists. | |
333 | ||
334 | Recommended Tools for Compilation | |
335 | ================================= | |
336 | ||
337 | In order for glibc-2.2 to build correctly on the ia64 you need at | |
338 | least the following versions of the GNU tools (the : | |
339 | ||
340 | * The Cygnus toolchain snapshot for the ia64 as of August 4 | |
aea6353a UD |
341 | including the provided set of patches. It is however recommend |
342 | you use the October 24 toolchain snapshot or a more recent version. | |
8f3f1e09 UD |
343 | |
344 | OR alternatively you can try the following (the Cygnus toolchain is | |
345 | the recommended solution): | |
346 | ||
347 | * GCC and binutils, GAS and GNU LD out of CVS from | |
aea6353a | 348 | sources.redhat.com as of August 28, 2000 or later. The CVS tree |
8f3f1e09 UD |
349 | may require special patches to work properly on the ia64. |
350 | ||
351 | Configuring and compiling GNU Libc for Linux/ia64 | |
352 | ================================================= | |
353 | ||
354 | The library requires Linux kernel version 2.4.0-test4-000728 or | |
aea6353a UD |
355 | later to funtion properly. Besides that it support for debug libraries |
356 | is currently untested. Hence the following options | |
8f3f1e09 UD |
357 | are required for configuring the library: |
358 | ||
aea6353a | 359 | --disable-debug --enable-kernel=2.4.0 |
8f3f1e09 UD |
360 | |
361 | It is also important that you make sure the library picks up the | |
362 | appropriate kernel header files, if you do not have recent enough | |
363 | kernel headers in /usr/src/linux/include, you should use the | |
364 | --with-headers=<path> option to specify the location. | |
365 | ||
366 | As an example I personally use the following options to configure | |
367 | the library: | |
368 | ||
369 | --disable-debug | |
8f3f1e09 UD |
370 | --disable-cvs |
371 | --enable-kernel=2.4.0 | |
372 | --host=ia64-linux | |
373 | --enable-add-ons=yes | |
374 | --prefix=/usr | |
375 | --with-headers=/home/jes/linux/include | |
376 | ||
377 | ||
378 | Good luck | |

396 | * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added. |
397 | ||
16b0f634 UD |
398 | * New xdr functions are added; some rpc functions are now 64bit clean. |
399 | ||
407d26b7 | 400 | * Fixed a number of bugs and memory leaks (especially in NIS+ code). |
16b0f634 UD |
401 | |
402 | * Fixed known incompatibilities with glibc 2.0. | |
403 | ||
407d26b7 | 404 | * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. |

417 | * Richard Henderson corrected size of struct timeval on Linux/Alpha to |
418 | conform to POSIX member type requirements. Symbol versions have been | |
419 | adjusted as needed within the library, and for direct use by applications, | |
420 | but there is potential for problems if third-party libraries use | |
421 | struct timeval as part of their interface. This does not present | |
422 | a problem for X and other "essential" system libraries. | |
423 | ||
c84142e8 | 424 | * An additional locale model to support C++ Standard Library locale |
1fb05e3d | 425 | model and probably more was implemented by Ulrich Drepper. |
c84142e8 | 426 | |
1fb05e3d | 427 | * Eric Youngdale and Ulrich Drepper implemented versioning of objects on |
c84142e8 UD |
428 | symbol level. |
429 | ||
430 | * Miles Bader provided the `argp' function family to support hierachical | |
431 | command line argument parsing, layered on top of getopt. | |
377a515b | 432 | |
cbdee279 | 433 | * strtod accepts new hexadecimal floating-point format from ISO C 9X. |
377a515b UD |
434 | |
435 | * printf has two new specifiers %a and %A to print hexadecimal flaoting-point | |
cbdee279 | 436 | numbers. |
377a515b | 437 | |
cbdee279 | 438 | * scanf recognizes the %a and %A format for scanning floating point numbers. |
e61abf83 | 439 | |
48869012 UD |
440 | * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides |
441 | information and interfaces for the available integer types. | |
e61abf83 | 442 | |
813f4f4d UD |
443 | * about 130 new math functions were added to implement the ISO C9x math |
444 | library. | |
445 | ||
e61abf83 | 446 | * the new header <complex.h> contains definitions of the complex math |
cbdee279 UD |
447 | functions from ISO C 9X. |
448 | ||
449 | * the new header <tgmath.h> defines generic macros to use complex or | |
450 | real valued functions. | |
e61abf83 | 451 | |
a5a0310d | 452 | * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2. |
e61abf83 | 453 | |
a5a0310d UD |
454 | * Andreas Jaeger provided a test suite for the math library. |
455 | ||
456 | * Mark Kettenis implemented the utmpx interface and an utmp daemon. | |
cbdee279 | 457 | |
440d13e2 | 458 | * Ulrich Drepper added character set conversion functions (iconv). |
cbdee279 UD |
459 | |
460 | * Optimized string functions have been added. | |
461 | ||
462 | * The localedata addon is now part of glibc. | |
2eb45444 UD |
463 | |
464 | * An implementation of profiling shared libraries was added by Ulrich Drepper. | |
ea278354 | 465 | |
48244d09 UD |
466 | * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching |
467 | daemon for NSS (nscd). | |

487 | It was just a common complain that using NIS+ unpacking the kernel is | |
0dee6738 | 488 | horribly slow. |
48244d09 | 489 | |
0dee6738 UD |
490 | [1] The old nscd implementation is not available anymore since it was |
491 | distributed with glibc up to version 2.0.98 and thus is now replaced. | |

494 | |
495 | * Mark Kettenis provided a Hesiod NSS module. | |
20833331 UD |
496 | |
497 | * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN | |
498 | and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper). | |
499 | ||
500 | * rcmd can now handle netgroups (Dick Streefland). | |
48244d09 | 501 | |
62595351 UD |
502 | * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott |
503 | Bambrough. | |

889 | \f | |
40a4b79f | 890 | Version 2.0 |
28f540f4 | 891 | |
d3669add RM |
892 | * GNU extensions are no longer declared by default. To enable them you |
893 | must define the macro `_GNU_SOURCE' in your program or compile with | |
894 | `-D_GNU_SOURCE'. | |
895 | ||
28f540f4 RM |
896 | * The library has changed from using GNU ld symbol aliases to using weak |
897 | symbols where available. The ELF object file format supports weak | |
898 | symbols; GNU ld also supports weak symbols in the a.out format. (There | |
899 | is also now support for other GNU ld extensions in ELF. Use the | |
787126fe RM |
900 | `--with-elf' option to configure to indicate you have ELF, and |
901 | `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion | |
28f540f4 RM |
902 | of many files which contained only symbol aliases, reducing the size of |
903 | the source and the compiled library; many other files were renamed to | |
904 | less cryptic names previously occupied by the symbol alias files. | |
dcf0671d UD |
905 | There is a new header file <elf.h> for programs which operate on |
906 | files in the ELF format. | |
49e522bf RM |
907 | |
908 | * Converted to Autoconf version 2, so `configure' has more options. | |
909 | Run `configure --help' to see the details. | |
910 | ||
911 | * The library can now be configured to build profiling, highly-optimized | |
b25c5d66 RM |
912 | (but undebuggable), and/or shared libraries (ELF with GNU ld only). The |
913 | `--enable-profile', `--enable-omitfp', and `--enable-shared' options to | |
914 | `configure' enable building these extra libraries. The shared library is | |
915 | built by default when using both ELF and GNU ld. When shared libraries | |
916 | are enabled, the new library `-ldl' is available for arbitrary run-time | |
917 | loading of shared objects; its interface is defined in <dlfcn.h>. The | |
918 | new header file <link.h> gives access to the internals of the run-time | |
33a934a3 UD |
919 | dynamic linker, `ld.so'. The shell script `ldd' is similar to the |
920 | application of same name on other systems and it provides information | |
921 | about dynamically linked binaries. | |
49e522bf | 922 | |
71733723 RM |
923 | * The C library now provides the run-time support code for profiling |
924 | executables compiled with `-pg'. Programs can control the profiling code | |
d3669add RM |
925 | through the interface in <sys/gmon.h>. The `gmon.out' files written by |
926 | the GNU C library can be read only by GNU `gprof' (from GNU binutils); | |
927 | the support for this file format was contributed by David Mosberger-Tang. | |
71733723 | 928 | |
f7eac6eb | 929 | * The math code has been replaced with a math library based on fdlibm from |
33a934a3 UD |
930 | Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by |
931 | Ian Taylor with `float' functions and by Ulrich Drepper with `long double' | |
932 | functions. The math functions now reside in a separate library, so | |
933 | programs using them will need to use `-lm' their linking commands. | |
934 | ||
935 | * John C. Bowman contributed optimized ix87 assembler inline functions. | |
f7eac6eb | 936 | |
5f0e6fc7 RM |
937 | * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' |
938 | mechanism similar to that found in Solaris 2. This is now used for the | |
33a934a3 UD |
939 | group, passwd, hosts, networks, services, protocols, rpc, ethers, |
940 | shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' | |
941 | file controls what services are used for each individual database. This | |
942 | works by loading shared libraries with names specified in `nsswitch.conf', | |
943 | so service modules can be changed or added at any time without even | |
944 | relinking any program. Currently there are the file, db, and NIS based | |
945 | NSS services available. | |
5f0e6fc7 | 946 | |
49e522bf RM |
947 | * The new functions `strtoq' and `strtouq' parse integer values from |
948 | strings, like `strtol' and `strtoul', but they return `long long int' and | |
949 | `unsigned long long int' values, respectively (64-bit quantities). | |
950 | ||
951 | * The new functions `strtof' and `strtold' parse floating-point values from | |
952 | strings, like `strtod', but they return `float' and `long double' values, | |
953 | respectively (on some machines `double' and `long double' are the same). | |
954 | ||
955 | * Ulrich Drepper has contributed new implementations of the floating-point | |
956 | printing and reading code used in the `printf' family of functions and | |
957 | `strtod', `strtof', and `strtold'. These new functions are perfectly | |
958 | accurate, and much faster than the old ones. | |
959 | ||
33a934a3 UD |
960 | * The implementation of the POSIX locale model was completely rewritten by |
961 | Ulrich Drepper. This includes the new programs `localedef' and `locale' | |
962 | to compile the POSIX locale definition. | |
963 | ||
964 | * The former dummy implementations of the strcoll and strxfrm function are | |
965 | now replaced by fully functional code contributed by Ulrich Drepper. The | |
966 | collation information comes from the POSIX locale definitions. | |
967 | ||
49e522bf RM |
968 | * The new header <langinfo.h> defines an interface for accessing |
969 | various locale-dependent data (using the locale chosen with `setlocale'). | |
970 | ||
f7eac6eb | 971 | * Ulrich Drepper has contributed a new suite of functions for operation on |
33a934a3 | 972 | wide-character and multibyte-character strings, in <wchar.h>; |
b7407d63 | 973 | and classification and case conversion of wide characters, in <wctype.h>. |
33a934a3 UD |
974 | These new functions are conforming to the ISO C, Amendement 1 specification. |
975 | ||
976 | * There is now a second implementation of the standard I/O library available. | |
977 | It comes from GNU libg++ as was written by Per Bothner, heavily modified | |
978 | by Hongjiu Lu and made thread safe by Ulrich Drepper. | |
f7eac6eb | 979 | |
71733723 | 980 | * You can now use positional parameter specifications in format strings |
49e522bf RM |
981 | for the `printf' and `scanf' families of functions. For example, |
982 | `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints | |
983 | ``Number 6, Mr Jones''. This is mainly useful when providing different | |
d365fd2c RM |
984 | format strings for different languages, whose grammars may dictate |
985 | different orderings of the values being printed. To support this | |
49e522bf | 986 | feature, the interface for `register_printf_handler' has changed; see |
d365fd2c | 987 | the header file <printf.h> for details. |
49e522bf RM |
988 | |
989 | * The `printf' and `scanf' families of functions now understand a new | |
990 | formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says | |
991 | to group numbers as indicated by the locale; for `scanf' and friends, this | |
992 | says to accept as valid only a number with all the proper grouping | |
993 | separators in the right places. In the default "C" locale, numbers are | |
994 | not grouped; but locales for specific countries will define the usual | |
995 | conventions (i.e. separate thousands with `,' in the US locale). | |
28f540f4 RM |
996 | |
997 | * The pgrp functions have been regularized, slightly incompatibly but much | |
998 | less confusingly. The core functions are now `getpgid' and `setpgid', | |
999 | which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no | |
1000 | argument) and BSD `setpgrp' (identical to `setpgid') functions are | |
1001 | provided for compatibility. There is no longer an incompatible `getpgrp' | |
1002 | with an argument declared under _BSD_SOURCE; no BSD code uses it. | |
1003 | ||
1004 | * The new header file <fts.h> and suite of functions simplify programs that | |
1005 | operate on directory trees. This code comes from 4.4 BSD. | |
1006 | ||
33a934a3 UD |
1007 | * The resolver code has been updated from the BIND 4.9.5-P1 release. |
1008 | Parts of the code were heavily modified by Ulrich Drepper to fit in the | |
1009 | NSS scheme used in glibc. | |
28f540f4 | 1010 | |
28f540f4 RM |
1011 | * There is a new malloc debugging hook `__memalign_hook'. |
1012 | ||
1013 | * There are new typedefs `ushort' for `unsigned short int' and `uint' for | |
1014 | `unsigned int' in <sys/types.h>. These are for compatibility only and | |
1015 | their use is discouraged. | |
1016 | ||
1017 | * The `-lmcheck' library to enable standard malloc debugging hooks is now | |
1018 | done differently, so that it works even without GNU ld. | |
787126fe | 1019 | |
22a1292a RM |
1020 | * New function `euidaccess' checks allowed access to a file like `access', |
1021 | but using the effective IDs instead of the real IDs. | |
49e522bf RM |
1022 | |
1023 | * The time zone data files have been updated for the latest and greatest | |
1024 | local time conventions of the countries of the world. | |
1025 | ||
1026 | * The new function `dirfd' extracts the file descriptor used by a DIR stream; | |
1027 | see <dirent.h>. | |
1028 | ||
1029 | * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface | |
1030 | for formatting floating-point numbers. They are provided only for | |
33a934a3 UD |
1031 | compatibility; new programs should use `sprintf' instead. There are |
1032 | also equivalent function for the `long double' floating-point type and | |
1033 | all functions also exist in a reentrant form. | |
342414a6 RM |
1034 | |
1035 | * The new auxiliary library `-lutil' from 4.4 BSD contains various | |
1036 | functions for maintaining the login-record files (primarily of use to | |
1037 | system programs such as `login'), and convenient functions for | |
1038 | allocating and initializing a pseudo-terminal (pty) device. | |
c709e372 RM |
1039 | |
1040 | * Ulrich Drepper has contributed new support for System V style | |
1041 | shared memory and IPC on systems that support it. | |
1042 | ||
1043 | * Ulrich Drepper has contributed several miscellaneous new functions found | |
1044 | in System V: The `hsearch' family of functions provide an effective | |
1045 | implementation of hash tables; `a64l' and `l64a' provide a very simple | |
1046 | binary to ASCII mapping; `drand48' and friends provide a 48-bit random | |
1047 | number generator. | |
1048 | ||
1049 | * Ulrich Drepper has contributed new reentrant counterparts for the | |
1050 | `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. | |
1051 | ||
1052 | * Ulrich Drepper has contributed new, highly-optimized versions of several | |
1053 | string functions for the i486/Pentium family of processors. | |
1054 | ||
71733723 | 1055 | * Ulrich Drepper has updated the Linux-specific code, based largely |
c709e372 | 1056 | on work done in Hongjiu Lu's version of GNU libc for Linux. |
33a934a3 UD |
1057 | The GNU library now supports Linux versions 2.0.10 and later, |
1058 | using the ELF object file format (i[3456]86-*-linux). | |
c709e372 | 1059 | |
d3669add RM |
1060 | * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). |
1061 | ||
33a934a3 UD |
1062 | * David Mosberger-Tang and Richard Henderson have ported the C library |
1063 | to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the | |
1064 | dynamic linking support for ELF/Alpha. | |
1065 | ||
1066 | * Richard Henderson contributed several Alpha optimized assembler function | |
1067 | for arithmetic and string handling. | |
d3669add | 1068 | |
c709e372 | 1069 | * Ulrich Drepper has contributed a new set of message catalog functions to |
40a4b79f RM |
1070 | support multiple languages using the <libintl.h> interface, for use with |
1071 | his new package GNU gettext. Translation volunteers have contributed | |
1072 | catalogs of the library's messages in Spanish, German, and Korean. | |
1073 | ||
1074 | * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' | |
1075 | program and the `catgets' function for reading the catalog files it | |
1076 | creates. (The <libintl.h> interface is preferred; we include the | |
1077 | <nl_types.h> interface using `catgets' only for source compatibility with | |
1078 | programs already written to use it.) | |
71733723 RM |
1079 | |
1080 | * New header file <values.h> gives SVID-compatible names for <limits.h> | |
1081 | constants. | |
1082 | ||
1083 | * Various new macros, declarations, and small header files for compatibility | |
1084 | with 4.4 BSD. | |
1085 | ||
1086 | * New function `group_member' is a convenient way to check if a process has | |
1087 | a given effective group ID. | |
1088 | ||
1089 | * When using GCC 2.7 and later, the socket functions are now declared in a | |
1090 | special way so that passing an argument of type `struct sockaddr_in *', | |
1091 | `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic | |
1092 | `struct sockaddr *' type, does not generate a type-clash warning. | |
1093 | ||
1094 | * New function `error' declared in header file <error.h> is a convenient | |
6d52618b | 1095 | function for printing error messages and optionally exiting; this is the |
71733723 RM |
1096 | canonical function used in GNU programs. The new functions `err', `warn', |
1097 | and friends in header file <err.h> are the canonical 4.4 BSD interface for | |
1098 | doing the same thing. | |
1099 | ||
1100 | * The <glob.h> interface has several new flags from 4.4 BSD that extend the | |
1101 | POSIX.2 `glob' function to do ~ and {...} expansion. | |
1102 | ||
1103 | * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. | |
33a934a3 | 1104 | `clearenv' which is used in POSIX.9 is also available. |
71733723 RM |
1105 | |
1106 | * New function `getsid' returns session ID number on systems that support it. | |
1107 | ||
f7eac6eb RM |
1108 | * We have incorporated the 4.4 BSD `db' library (version 1.85). New header |
1109 | files <db.h> and <mpool.h> provide a rich set of functions for several | |
1110 | types of simple databases stored in memory and in files, and <ndbm.h> is | |
6d52618b | 1111 | an old `ndbm'-compatible interface using the `db' functions. Link with |
999493cb | 1112 | `-ldb' to get these functions. |
f7eac6eb RM |
1113 | |
1114 | * New macro `strdupa' copies a string like `strdup', but uses local stack | |
1115 | space from `alloca' instead of dynamic heap space from `malloc'. | |
52e9a9d1 RM |
1116 | |
1117 | * New function `strnlen' is like `strlen' but searches only a given maximum | |
33a934a3 UD |
1118 | number of characters for the null terminator. `stpncpy', `strndup' and |
1119 | `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' | |
1120 | function. | |
40a4b79f RM |
1121 | |
1122 | * New function `statfs' in header <sys/statfs.h>. | |
1123 | ||
1124 | * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader | |
1125 | provide convenient functions for operating on blocks of null-terminated | |
1126 | strings. | |
1127 | ||
1128 | * A new suite of functions in <utmp.h> handle all the details of reading | |
1129 | and writing the utmp file. | |
33a934a3 UD |
1130 | |
1131 | * An implementation of the NIS/YP(tm) based NSS service was contributed by | |
1132 | Thorsten Kukuk. | |
1133 | ||
1134 | * Paul Eggert and Ulrich Drepper modified the `strftime' function to be | |
1135 | completely POSIX compliant and also implemented the extended functionality | |
1136 | to handle alternate digit representation and alternate era date formats. | |
1137 | ||
1138 | * Ulrich Drepper provided an implementation of the `strptime' function | |
1139 | defined in XPG4.2 which transforms a string into a `struct tm' value. | |
1140 | ||
1141 | * Paul Eggert provided the tzselect shell script as part of the timezone | |
1142 | code. The shell script makes it easy to select the correct timezone | |
1143 | specification. | |
1144 | ||
1145 | * The implementation of the malloc family of functions is completely replaced | |
1146 | by a new implementation by Doug Lea with many improvements by Wolfram Gloger. | |
1147 | The implementation uses the mmap function (if available) and it is | |
1148 | optimized for the use in multi threaded programs. | |
1149 | ||
1150 | * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of | |
1151 | functions. This new functionality is usable by specifying a special | |
1152 | salt string and it is compatible with implementation on *BSD systems. | |
1153 | ||
1154 | * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: | |
1155 | `getsubopt' to handle second level command line options, `bsd_signal' | |
1156 | to access BSD style `signal' functionality, the obsolete `regexp' style | |
1157 | expression matcher. | |
1158 | ||
1159 | * the `lchown' function is available on system which support this | |
1160 | functionality. | |
1161 | ||
1162 | * The implementation of the shadow password handling function was contributed | |
1163 | by Ulrich Drepper. | |
1164 | ||
1165 | * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. | |
1166 | ||
1167 | * POSIX.1g support was added. The <sys/select.h> header is available, | |
1168 | `isfdtype' and `pselect' are implemented. Craig Metz contributed an | |
1169 | implementation of `getaddrinfo'. | |
28f540f4 RM |
1170 | \f |
1171 | Version 1.09 | |
1172 | ||
1173 | * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. | |
1174 | ||
1175 | * New header file <fstab.h> and new functions `getfsspec', `getfsent' and | |
1176 | friends, for parsing /etc/fstab. This code comes from 4.4 BSD. | |
1177 | ||
1178 | * The new function `daemon' from 4.4 BSD is useful for server programs that | |
1179 | want to put themselves in the background. | |
1180 | ||
1181 | * Joel Sherrill has contributed support for several standalone boards that | |
1182 | run without an operating system. | |
1183 | ||
1184 | * `printf', `scanf' and friends now accept a `q' type modifier for long | |
1185 | long int as well as `ll'. Formats using these might be `%qu' or `%lld'. | |
1186 | ||
1187 | * All of the code taken from BSD (notably most of the math and networking | |
1188 | routines) has been updated from the BSD 4.4-Lite release. | |
1189 | ||
1190 | * The resolver code has been updated from the BIND-4.9.3-BETA9 release. | |
1191 | ||
1192 | * The new functions `getdomainname' and `setdomainname' fetch or change the | |
1193 | YP/NIS domain name. These are system calls which exist on systems which | |
1194 | have YP (aka NIS). | |
1195 | ||
1196 | * The time zone data files have been updated for the latest international | |
1197 | conventions. | |
1198 | ||
1199 | * The SunRPC programs `portmap' and `rpcinfo' are now installed in | |
1200 | $(sbindir) (usually /usr/local/sbin) instead of $(bindir). | |
1201 | \f | |
1202 | Version 1.08 | |
1203 | ||
1204 | * The C library now includes support for Sun RPC, from Sun's free | |
1205 | RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs | |
1206 | are included. (There is still no support for YP.) | |
1207 | ||
1208 | * Tom Quinn has contributed a port of the C library to SGI machines running | |
1209 | Irix 4 (mips-sgi-irix4). | |
1210 | ||
1211 | * The new `lockf' function is a simplified interface to the locking | |
1212 | facilities of `fcntl', included for compatibility. | |
1213 | ||
1214 | * New time functions `timegm', `timelocal', and `dysize' for compatibility. | |
1215 | ||
1216 | * New header file <sys/timeb.h> and new function `ftime' for compatibility. | |
1217 | ||
1218 | * New header files <poll.h> and <sys/poll.h> and new function `poll' for | |
1219 | compatibility. | |
1220 | ||
1221 | * The error message printed by `assert' for a failed assertion now includes | |
1222 | the name of the program (if using GNU ld) and the name of the calling | |
1223 | function (with versions of GCC that support this). | |
1224 | ||
1225 | * The `psignal' function is now declared in <signal.h>, not <stdio.h>. | |
1226 | ||
1227 | * The library now includes the <sys/mman.h> header file and memory | |
1228 | management functions `mmap', `munmap', `mprotect', `msync', and | |
1229 | `madvise', on systems that support those facilities. | |
1230 | ||
1231 | * The interface for `mcheck' has changed slightly: the function called to | |
1232 | abort the program when an allocation inconsistency is detected now takes | |
1233 | an argument that indicates the type of failure. The new function | |
1234 | `mprobe' lets you request a consistency check for a particular block at | |
1235 | any time (checks are normally done only when you call `free' or `realloc' | |
1236 | on a block). | |
1237 | ||
1238 | * It is now possible to easily cross-compile the C library, building on one | |
1239 | system a library to run on another machine and/or operating system. All | |
1240 | you need to do is set the variable `HOST_CC' in `configparms' to the | |
1241 | native compiler for programs to run on the machine you are building on (a | |
1242 | few generator programs are used on Unix systems); set `CC' to the | |
1243 | cross-compiler. | |
1244 | ||
1245 | * The new function `fexecve' (only implemented on the GNU system) executes | |
1246 | a program file given a file descriptor already open on the file. | |
1247 | \f | |
1248 | Version 1.07 | |
1249 | ||
1250 | * Brendan Kehoe has contributed most of a port to the DEC Alpha | |
1251 | running OSF/1 (alpha-dec-osf1). He says it is 75% complete. | |
1252 | ||
1253 | * You can set the variable `libprefix' in `configparms' to specify a prefix | |
1254 | to be prepended to installed library files; this makes it easy to install | |
1255 | the GNU C library to be linked as `-lgnuc' or whatever. | |
1256 | ||
1257 | * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It | |
1258 | copies a limited number of characters from a string, and returns the | |
1259 | address of the last character written. | |
1260 | ||
1261 | * You no longer need to check for whether the installed `stddef.h' is | |
1262 | compatible with the GNU C library. configure now checks for you. | |
1263 | ||
1264 | * You can now define a per-stream `fileno' function to convert the | |
1265 | stream's cookie into an integral file descriptor. | |
1266 | ||
1267 | * ``malloc (0)'' no longer returns a null pointer. Instead, it | |
1268 | allocates zero bytes of storage, and returns a unique pointer which | |
1269 | you can pass to `realloc' or `free'. The behavior is undefined if | |
1270 | you dereference this pointer. | |
1271 | ||
1272 | * The C library now runs on Sony NEWS m68k machines running either | |
1273 | NewsOS 3 or NewsOS 4. | |
1274 | ||
1275 | * The new `syscall' function is a system-dependent primitive function | |
1276 | for invoking system calls. It has the canonical behavior on Unix | |
1277 | systems, including unreliable return values for some calls (such as | |
1278 | `pipe', `fork' and `getppid'). | |
1279 | ||
1280 | * The error code `EWOULDBLOCK' is now obsolete; it is always defined | |
1281 | to `EAGAIN', which is the preferred name. On systems whose kernels | |
1282 | use two distinct codes, the C library now translates EWOULDBLOCK to | |
1283 | EAGAIN in every system call function. | |
1284 | \f | |
1285 | Version 1.06 | |
1286 | ||
1287 | * The GNU C Library Reference Manual is now distributed with the library. | |
1288 | `make dvi' will produce a DVI file of the printed manual. | |
1289 | `make info' will produce Info files that you can read on line using C-h i | |
1290 | in Emacs or the `info' program. | |
ea278354 | 1291 | Please send comments on the manual to bug-glibc-manual@gnu.org. |
28f540f4 RM |
1292 | |
1293 | * The library now supports SVR4 on i386s (i386-unknown-sysv4). | |
1294 | ||
1295 | * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. | |
1296 | ||
1297 | * Jason Merrill has contributed a port to the Sequent Symmetry running | |
1298 | Dynix version 3 (i386-sequent-dynix). | |
1299 | ||
1300 | * The library has been ported to i386s running SCO 3.2.4 (also known as SCO | |
1301 | ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). | |
1302 | ||
1303 | * New function `memory_warnings' lets you arrange to get warnings when | |
1304 | malloc is running out of memory to allocate, like Emacs gives you. | |
1305 | ||
1306 | * The C library now contains the relocating allocator used in Emacs 19 for | |
1307 | its editing buffers. This allocator (ralloc) minimizes allocation | |
1308 | overhead and fragmentation by moving allocated regions around whenever it | |
1309 | needs to. You always refer to a ralloc'd region with a "handle" (a | |
1310 | pointer to a pointer--an object of type `void **'). | |
1311 | ||
1312 | * There is a new `printf' format: `%m' gives you the string corresponding | |
1313 | to the error code in `errno'. | |
1314 | ||
1315 | * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' | |
1316 | or `%[' conversion, but instead of filling in a fixed-sized buffer you | |
1317 | pass, the `a' modifier says to fill in a `char **' you pass with a | |
1318 | malloc'd string. | |
1319 | ||
1320 | * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and | |
1321 | `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a | |
1322 | name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. | |
1323 | ||
1324 | * `mkstemp' is a traditional Unix function to atomically create and open a | |
1325 | uniquely-named temporary file. | |
1326 | \f | |
1327 | Version 1.05 | |
1328 | ||
1329 | * The standard location for the file that says what the local timezone is | |
1330 | has changed again. It is now `/usr/local/etc/localtime' (or more | |
1331 | precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. | |
1332 | ||
1333 | * The distribution no longer contains any files with names longer than 14 | |
1334 | characters. | |
1335 | ||
1336 | * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. | |
1337 | These are set by the new `trusted' and `console' keywords in `/etc/ttys'. | |
1338 | ||
1339 | * New functions `ttyslot' and `syslog' from 4.4 BSD. | |
1340 | \f | |
1341 | Version 1.04 | |
1342 | ||
1343 | * The configuration process has changed quite a bit. The `configure' | |
1344 | script is now used just like the configuration scripts for other GNU | |
1345 | packages. The `sysdeps' directory hierarchy is much rearranged. | |
1346 | The file `INSTALL' explains the new scheme in detail. | |
1347 | ||
1348 | * The header files no longer need to be processed into ANSI C and | |
1349 | traditional C versions. There is just one set of files to install, and | |
1350 | it will work with ANSI or old C compilers (including `gcc -traditional'). | |
1351 | ||
1352 | * Brendan Kehoe and Ian Lance Taylor have ported the library to the | |
1353 | MIPS DECStation running Ultrix 4. | |
1354 | ||
1355 | * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. | |
1356 | Tom Quinn contributed the initial code. The GNU C library can NOT yet be | |
1357 | made itself into a shared library. | |
1358 | ||
1359 | * Yet further improved support for the i386, running 4.3 BSD-like systems | |
1360 | (such as Mach 3 with the Unix single-server), or System V. | |
1361 | ||
1362 | * New function `strncasecmp' to do case-insensitive string comparison | |
1363 | with limited length. | |
1364 | ||
1365 | * New function `strsep' is a reentrant alternative to `strtok'. | |
1366 | ||
1367 | * New functions `scandir' and `alphasort' for searching directories. | |
1368 | ||
1369 | * New function `setenv' is a better interface to `putenv'. | |
1370 | ||
1371 | * Ian Lance Taylor has contributed an implementation of the SVID `ftw' | |
1372 | function for traversing a directory tree. | |
1373 | ||
1374 | * The GNU obstack package is now also part of the C library. | |
1375 | The new function `open_obstack_stream' creates a stdio stream that | |
1376 | writes onto an obstack; `obstack_printf' and `obstack_vprintf' do | |
1377 | formatted output directly to an obstack. | |
1378 | ||
1379 | * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), | |
1380 | cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. | |
1381 | ||
1382 | * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. | |
1383 | ||
1384 | * The new functions `strfry' and `memfrob' do mysterious and wonderful | |
1385 | things to your strings. | |
1386 | ||
1387 | * There are some new test programs: test-fseek, testmb, and testrand. | |
1388 | ||
1389 | * Some work has been done to begin porting the library to 4.4 BSD and Linux. | |
1390 | These ports are not finished, but are a good starting place for really | |
1391 | supporting those systems. | |
1392 | ||
1393 | * `/etc/localtime' is now the standard location for the file that says what | |
1394 | the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. | |
1395 | This follows the general principle that `/etc' is the place for all local | |
1396 | configuration files. | |
1397 | ||
1398 | * The C library header files now use `extern "C"' when used by the C++ | |
1399 | compiler, so the C library should now work with C++ code. | |
1400 | ||
1401 | * The header file <bstring.h> is gone. <string.h> now declares bcopy, | |
56ddf355 UD |
1402 | bcmp, bzero, and ffs. (Update: nowadays these functions are declared |
1403 | in <strings.h>.) | |
28f540f4 RM |
1404 | |
1405 | * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting | |
1406 | function which uses the `merge sort' algorithm, and is said to be | |
1407 | significantly faster than the old GNU `qsort' function. Merge sort is | |
1408 | now the standard `qsort' function. The new algorithm can require a lot | |
1409 | of temporary storage; so, the old sorting function is called when the | |
1410 | required storage is not available. | |
1411 | ||
1412 | * The C library now includes Michael Glad's Ultra Fast Crypt, which | |
1413 | provides the Unix `crypt' function, plus some other entry points. | |
28f540f4 RM |
1414 | |
1415 | * The code and header files taken from 4.4 BSD have been updated with the | |
1416 | latest files released from Berkeley. | |
