6f5c3117 | 11 | |
1fdd89a7 UD |
12 | * Correct declarations of string function when used in C++ code. This |
13 | could lead to compile error for invalid C++ code. | |
14 | ||
6cbe890a UD |
15 | * XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are |
16 | now in POSIX. | |

7b3ba2c4 UD |
48 | * Implement "b" mode for fmemopen. In this mode writes writes don't |
49 | implicitly add a NUL byte and seeks from the end of the buffer really | |
50 | use the buffer end, not the string length as the basis. | |
51 | Implemented by Ulrich Drepper. | |
52 | ||
e038616f UD |
53 | * Many functions, exported and internal, now atomically set the close-on-exec |
54 | flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper. | |
48b22986 | 55 | |
bf837fa3 UD |
56 | * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu, |
57 | Sinhala) | |

98 | Implemented by Jakub Jelinek and Ulrich Drepper. | |
99 | ||
100 | * Extend fortification to C++. Implemented by Jakub Jelinek. | |
101 | ||

131 | ||
132 | + New iconv modules: MAC-CENTRALEUROPE, ISO-8859-9E, KOI8-RU. | |
133 | Implemented by Ulrich Drepper. | |
e1db0493 | 134 | \f |
11bf311e | 135 | Version 2.6 |
46c38bd7 | 136 | |
bce20b9a | 137 | * New Linux interfaces: epoll_pwait, sched_getcpu. |
46c38bd7 | 138 | |
4a44ce79 UD |
139 | * New generic interfaces: strerror_l. |
140 | ||
b21fa963 UD |
141 | * nscd can now cache the services database. Implemented by Ulrich Drepper. |
142 | ||
3af48b5b UD |
143 | \f |
144 | Version 2.5 | |
145 | ||
146 | * For Linux, the sorting of addresses returned by getaddrinfo now also | |
457b559e UD |
147 | handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled. |
148 | Implemented by Ulrich Drepper. | |
3af48b5b | 149 | |
3142b1ac UD |
150 | * Allow system admin to configure getaddrinfo with the /etc/gai.conf file. |
151 | Implemented by Ulrich Drepper. | |
152 | ||
871b9158 | 153 | * New Linux interfaces: splice, tee, sync_file_range, vmsplice. |
1e528c6e UD |
154 | |
155 | * New iconv module for MIK. Contributed by Alexander Shopov. | |
3af48b5b | 156 | |
3142b1ac UD |
157 | * For sites with broken group and/or passwd database, the auto-propagate |
158 | option of nscd can prevent creating ID lookup entries from the results | |
159 | of a name lookup and vice versa. This usually is no problem but some | |
457b559e | 160 | site might have problems with the default behavior. |
3142b1ac UD |
161 | Implemented by Ulrich Drepper. |
162 | ||
07bfff20 | 163 | * Iterating over entire database in NIS can be slow. With the |
3142b1ac UD |
164 | SETENT_BATCH_READ option in /etc/default/nss a system admin can decide |
165 | to trade time for memory. The entire database will be read at once. | |
166 | Implemented by Ulrich Drepper. | |
167 | ||
07bfff20 UD |
168 | * The interfaces introduced in RFC 3542 have been implemented by |
169 | Ulrich Drepper. | |
170 | ||
871b9158 UD |
171 | * Support for the new ELF hash table format was added by Ulrich Drepper. |
172 | ||
d5ba53f9 UD |
173 | * Support for priority inheritance mutexes added by Jakub Jelinek and |
174 | Ulrich Drepper. | |
175 | ||
ad2a3c07 UD |
176 | * Support for priority protected mutexes added by Jakub Jelinek. |
177 | ||

186 | IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba. | |
1aa4e40a | 187 | |
4973cbe5 UD |
188 | More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097, |
189 | IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144, | |
190 | IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517, | |
191 | IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712, | |
192 | IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed | |
193 | by Masahide Washizawa. | |
194 | ||
1aa4e40a UD |
195 | * It is now possible to install audit libraries for the dynamic linker using |
196 | LD_AUDIT. Implemented by Ulrich Drepper. | |
da0eaa47 RM |
197 | |
198 | * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no | |
199 | longer supported. The new NPTL implementation requires Linux 2.6 kernels. | |
200 | For a libc and libpthread that works well on Linux 2.4 kernels, we | |
201 | recommend using the stable 2.3 branch. | |
4973cbe5 | 202 | |
35129bc0 RM |
203 | * The new function open_wmemstream acts like open_memstream, |
204 | but uses a wchar_t wide character buffer. | |
205 | ||
206 | * The new function ppoll is an improved version of poll, similar to pselect. | |
207 | ||
208 | * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat, | |
209 | futimesat, faccessat, mkdirat, mkfifoat, mknodat, | |
210 | renameat, unlinkat, linkat, symlinkat, readlinkat. | |
211 | ||
212 | * New Linux kernel system calls: unshare, | |
213 | inotify_init, inotify_add_watch, inotify_rm_watch. | |
214 | ||
215 | * The euidaccess function is now also known by the alias eaccess, | |
216 | for compatibility with some other systems. | |
217 | ||
218 | * Timezone data updated to 2006b version. | |
137e6462 | 219 | \f |
e6a9beca RM |

227 | 1099, 1100, 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, | |
228 | 1110, 1111, 1112, 1113, 1125, 1137, 1138, 1249, 1250, 1251, 1252, | |
229 | 1253, 1254, 1350, 1358, 1394, 1438, 1498, 1534 | |
230 | ||
231 | Visit <http://sources.redhat.com/bugzilla/> for the details of each bug. | |
232 | ||
233 | * As of this release, GCC 4 can be used to compile the C Library. | |
234 | ||
235 | * Timezone data updated to 2005m version. | |
236 | \f | |
da232bf9 RM |
237 | Version 2.3.5 |
238 | ||
239 | * The following bugs are resolved with this release: | |
240 | ||
241 | 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719, | |

247 | \f | |
a55bda85 UD |
248 | Version 2.3.4 |
249 | ||
250 | * Support for RFC 3678. Real implementations exist only for Linux so far. | |
251 | Implemented by Ulrich Drepper. | |
8a1f658b UD |
252 | |
253 | * nscd can now cache entries persistently. Expiring entries are reloaded. | |
254 | For speedups the cache can be shared in memory with client processes. | |
255 | Implemented by Ulrich Drepper. | |
256 | ||
257 | * nscd can now perform SELinux checks. | |
258 | Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>. | |
259 | ||
0325dd20 | 260 | * getaddrinfo queries are now cached. Canonical name lookup is performed |
8a1f658b UD |
261 | efficiently. |
262 | Implemented by Ulrich Drepper. | |
263 | ||
264 | * The nothrow function attribute is used when headers are used by gcc when | |
265 | compiling C code. This can avoid significant amounts of exception | |
266 | handling data. | |
267 | ||
268 | * The malloc functions perform more error checking and are stricter when | |
269 | it comes to reacting on errors. The default action is to terminate | |
0325dd20 | 270 | the process after showing an error message. Implemented by Ulrich Drepper. |
8a1f658b UD |
271 | |
272 | * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int | |
0325dd20 UD |
273 | lookups anymore unless explicitly requested. Implemented by Ulrich Drepper. |
274 | ||
275 | * Namespaces in ld.so are implemented. DSOs can be loaded in separate | |
276 | namespaces using the new function dlmopen(). This feature is of course, | |
277 | like most other dynamic loading functionality, not available in statically | |
278 | linked applications. Implemented by Ulrich Drepper. | |
279 | ||
280 | * Low-overhead boundary checking variants of string and some stdio functions | |
281 | were added. These are to be used in conjunction with a gcc patch by | |
282 | Jakub Jelinek which adds calls to these functions if possible. | |
720817e7 RM |
283 | Implemented by Jakub Jelinek and Ulrich Drepper. |
284 | ||
285 | * Old code for several operating systems and machine architectures that | |
286 | have not been in working condition in a long time have been removed from | |
287 | the main source tree maintained by the GNU C Library's maintainers. | |
288 | These files are now reside in the separate `ports' source module | |
289 | that is usable as an add-on when building the library. | |
a55bda85 | 290 | \f |
3a601d31 RM |
291 | Version 2.3.3 |
292 | ||
45e4762c RM |
293 | * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to |
294 | interrogate the dynamic linker, compatible with the Solaris interface. | |
295 | ||
3a601d31 RM |
296 | * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64; |
297 | implemented by Paul Mackerras, Steven Munroe, and Roland McGrath. | |
925c3c5c | 298 | |
69be6aaf | 299 | * getifaddrs now uses the netlink interface on Linux to get its information. |
925c3c5c UD |
300 | Implemented by Thorsten Kukuk. |
301 | ||
302 | * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF. | |
303 | Implemented by Ulrich Drepper. | |
97fd3a30 UD |
304 | |
305 | * support for non-executable stacks on x86 has been added. Changes mostly | |
306 | by Roland McGrath. | |
307 | ||
c5af724c | 308 | * regex is now much faster for multibyte locales. Changes by Jakub Jelinek |
97fd3a30 UD |
309 | and Ulrich Drepper. |
310 | ||
311 | * getaddrinfo now performs destination address selection according to | |
312 | RFC 3484. | |
3a601d31 | 313 | \f |
747bf98e RM |
314 | Version 2.3.2 |
315 | ||
f87277f2 RM |
316 | * Thread-safe interfaces for many functions that access locale data |
317 | were added in version 2.3, but these features were omitted from NEWS. | |
318 | Many functions have variants with an `_l' suffix that take a `locale_t' | |
319 | object as a parameter rather than consulting the current locale. | |
320 | The new functions `newlocale', `duplocale', and `freelocale' in <locale.h> | |
321 | create and maintain `locale_t' objects. Additionally, the new function | |
322 | `uselocale' sets "the current locale" (as used by functions not so | |
323 | parameterized) set for an individual thread. These features were added | |
324 | in version 2.3, implemented by Ulrich Drepper and Roland McGrath. | |
325 | ||
747bf98e RM |
326 | * The functions getresuid, getresgid, setresuid, and setresgid, which |
327 | have long been available on Linux, are now declared in <unistd.h> | |
328 | and are now also available on the Hurd. | |
329 | ||
330 | * ELF thread-local storage support (TLS) now works on x86-64. | |
d62507dd RM |
331 | |
332 | * The new dynamic string token $LIB is expanded in shared library names. | |
333 | This normally expands to lib, but on some 64-bit platforms to lib64 instead. | |
52a16e58 | 334 | |
f87277f2 RM |
335 | * Aldy Hernandez contributed complete software floating point support for |
336 | PowerPC machines with no FPU. | |
337 | ||
52a16e58 | 338 | * fexecve is implemented on Linux. |
f9ad060c | 339 | |
f87277f2 RM |
340 | * The `btowc' function should work at least twice as fast due to |
341 | specialized callbacks in the iconv modules. Implemented by Bruno Haible. | |
9ef0a840 UD |
342 | |
343 | * With approriate thread add-ons cancelable functions are now implemented | |
344 | in libc.so as well. No need to call the function in libpthread. This | |
345 | change allowed to finally disable the incorrect and expensive handling | |
346 | of weak definition in ld.so. | |
347 | ||
348 | * Yet more PLT entries in libc.so have been removed. We finally arrived | |
349 | at the bare minimum. Startup times improved appropriately. | |
350 | ||
351 | * Support for the new Linux/x86 system call interface was added. The | |
352 | AT_SYSINFO auxiliary vector entry is recognized and handled. | |
747bf98e | 353 | \f |
03a2c647 | 354 | Version 2.3 |
37fb1084 | 355 | |
03a2c647 UD |
356 | * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164 |
357 | charsets. | |
358 | ||
359 | * iconv (the program and the interface) now accepts empty names (excluding | |
360 | options like //TRANSLIT) to mean "use charset of current locale". | |
47e8b443 | 361 | |
bb0ec5bd | 362 | * localedef can now transliterate characters in strings which are not in |
47e8b443 | 363 | the provided charmap. The information from the input locale is used. |
c17f665b UD |
364 | |
365 | * Prelinking support was added for ELF targets. This requires additional | |
366 | tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek. | |
8e57fc70 | 367 | |
bb0ec5bd | 368 | * Read-only stdio streams now use mmap to speed up operation by eliminating |
91e6367e UD |
369 | copying and buffer underflows. To use add 'm' to the mode string of |
370 | the fopen/fdopen/freopen call. Implemented by Ulrich Drepper. | |
207b66ce UD |
371 | |
372 | * The malloc functions were completely rewritten by Wolfram Gloger based | |
373 | on Doug Lea's malloc-2.7.0.c. | |
3b0bdc72 | 374 | |
bb0ec5bd | 375 | * Isamu Hasegawa contributed a completely new and POSIX-conformant |
3b0bdc72 | 376 | implementation of regex. |
02779eaa UD |
377 | |
378 | * Bruno Haible upgraded the iconv and locale implementation to support | |
379 | Unicode 3.2. | |
be45f421 | 380 | |
bb0ec5bd RM |
381 | * Contents of the LC_* and LANG environment variables in the CEN style are |
382 | not recognized anymore. It never was used. Change by Ulrich Drepper. | |
be45f421 | 383 | |
bb0ec5bd RM |
384 | * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF |
385 | thread-local storage (TLS) ABI on some platforms. | |
386 | Changes by Ulrich Drepper. SH support by Kaz Kojima. | |
be45f421 UD |
387 | |
388 | * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213, | |
f87277f2 | 389 | EUC-JISX0213, and TSCII. |
a753ffb2 RM |
390 | |
391 | * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs': | |
392 | BSD-compatible interface for getting all network interface addresses. | |
393 | Implementation for IPv4 by Roland McGrath. | |
6a9340b5 UD |
394 | |
395 | * Loading of locale data is faster due to the introduction of a locale | |
396 | archive. Implemented by Roland McGrath and Ulrich Drepper. | |
dd4f2115 UD |
397 | |
398 | * Startup times are significantly reduced by not using exported functions | |
399 | inside the library itself. Changes by Jakub Jelinek, Roland McGrath, | |
400 | and Ulrich Drepper. | |
c843e065 RM |
401 | |
402 | * Steven Munroe contributed a port to PowerPC64/Linux. | |
403 | \f | |
45061a15 RM |
404 | Version 2.2.6 |
405 | ||
406 | * The Hurd now uses the GNU libio implementation of stdio rather than the | |
407 | old GNU stdio implementation, and uses a new ABI (libc.so.0.3). | |
408 | ||
409 | * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file | |
410 | with the same behavior as the Linux system call of the same name. | |
03a2c647 | 411 | \f |
a8ae31c2 UD |
412 | Version 2.2.5 |
413 | ||
76321a25 AJ |
414 | * Stephen Moshier implemented log2, log10, powl and cbrtl for the |
415 | 128-bit long double format. | |
a8ae31c2 | 416 | |
557a9213 UD |
417 | * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160, |
418 | IBM1161, and IBM1162 charsets. | |
a8ae31c2 | 419 | |

a8ae31c2 | 421 | |
7d0c5823 RM |
422 | * Peter Bruin contributed a port to PowerPC/Hurd. |
423 | ||
a8ae31c2 UD |
424 | * libc functions using I/O streams now can handle wide-oriented streams |
425 | as well. | |
426 | ||
45061a15 RM |
427 | * optimizations in the dynamic linker. Binaries created by recent binutils |
428 | versions start up quicker due to reduced time spent on relocations. | |
8e57fc70 UD |
429 | |
430 | * Support for use of gcc3 added by Jakub Jelinek and HJ Lu. | |
7d0c5823 | 431 | \f |
33996419 AJ |
432 | Version 2.2.4 |
433 | ||
2995f70e | 434 | * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, |
aff17a50 | 435 | asinh, atanh, j0 for the 128-bit long double format. |
8fee1bb0 UD |
436 | |
437 | * Bruno Haible updated all the code handling Unicode in some form to | |
438 | support Unicode 3.1. | |
86dbe05e UD |
439 | |
440 | * Speed of regex for single-byte locales is back to previous levels. | |
441 | Patch by Isamu Hasegawa. | |
045fcd26 | 442 | |
69d5f925 | 443 | * Alpha, SPARC, and IA-64 now also using floating stacks. |
045fcd26 | 444 | |
69d5f925 | 445 | * Startup time of internationalized applications greatly improved through |
045fcd26 UD |
446 | iconv cache. Use iconvconfig to generate the cache file. |
447 | Contributed by Ulrich Drepper. | |
448 | ||
449 | * The IA-64 specific part of ld.so was rewritten to eliminate some pretty | |
450 | severe performance problems. Patch by David Mosberger. | |
451 | ||
452 | * The Hurd port got a lot more functionality like AIO, various stdio | |
453 | extensions, etc. Mainly done by Roland McGrath. | |
129d706d UD |
454 | |
455 | * mtrace can now lookup symbols in shared libraries. | |
33996419 | 456 | \f |
2ace5721 UD |
457 | Version 2.2.3 |
458 | ||
1746f2b0 | 459 | * Intel's IA-64 math library is largely integrated. It provides fast and |
2ace5721 UD |
460 | accurate implementatations for most basic and standard math functions |
461 | in float, double, and long double format. | |
462 | ||
f128331c | 463 | * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, |
b8750342 UD |
464 | and asin for the 96-bit long double format and asin, log, tan for the |
465 | 128-bit long double format. | |
07f951e4 | 466 | |
e4d82761 UD |
467 | * The beginning of a last-bit accurate math library by IBM Haifa were added. |
468 | The basic double functions exist today. Contributed by Abraham Ziv | |
469 | <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis | |
470 | <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. | |
471 | ||
2ace5721 UD |
472 | * An asynchronous name lookup library was added. The interface is designed |
473 | after POSIX AIO. The proposal was circulated beforehand to get comments. | |
474 | No negative ones came in. Implemented by Ulrich Drepper. | |
b8a8413c UD |
475 | |
476 | * Port to S390/64bit contributed by Martin Schwidefsky | |
477 | <schwidefsky@de.ibm.com>. | |
a66f0958 UD |
478 | |
479 | * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family | |
480 | of functions for Linux/IA-64. | |
481b550f UD |
481 | |
482 | * The RPC code is now thread safe. Threads can now use the same service | |
483 | of different services at the same time. Patch by Eric Norum | |
484 | <eric.norum@usask.ca> with some help by Ulrich Drepper. | |
f128331c UD |
485 | |
486 | * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext | |
487 | family of functions for Linux/S390. | |
232fdf8c UD |
488 | |
489 | * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family | |
490 | of functions for Linux/x86. | |
eacde9d0 UD |
491 | |
492 | * Port to Linux/CRIS contributed by Axis Communications. | |
2ace5721 | 493 | \f |
306eeae5 UD |
494 | Version 2.2.2 |
495 | ||
464d97ec | 496 | * Lots of headers were cleaned up. Using the tool in the conform/ subdir |
306eeae5 UD |
497 | we can now check for namespace violations and missing declarations. The |
498 | result is that almost all headers are now Unix-compliant (as defined in | |
499 | the upcoming XPG6). The negative side is that some programs might need | |
500 | corrections, too, if they depend on the incorrect form of the headers in | |
501 | previous versions which defined too many symbols and included too many | |
502 | other headers. | |
464d97ec UD |
503 | |
504 | * regex now handles multibyte character sets correctly. | |
505 | Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. | |
506 | ||
507 | * iconv (the program) does now conform to the upcoming XPG6 and handles | |
508 | charmaps. Instead of the charset names the path of charmaps can be | |
509 | provided and the conversion happens based on this data. | |
510 | Contributed by Ulrich Drepper. | |
511 | ||
512 | * The locale program now provides detailed information about the installed | |
513 | locales. While | |
514 | ||
515 | locale -a | |
516 | ||
517 | only lists the names of the supported locales | |
518 | ||
519 | locale -a --verbose | |
520 | ||
521 | provides details such as country, language, and codeset name. | |
522 | Contributed by Ulrich Drepper. | |
306eeae5 | 523 | \f |
d2defdc4 UD |
524 | Version 2.2.1 |
525 | ||
526 | * The gencat program now parses the input file according to the charset | |
527 | selected by the LC_CTYPE category. This is important for stateful | |
528 | character sets. To make generating catalogs easier there is a way | |
529 | to overwrite the charset selected by the locale: before the first | |
530 | message or $ quote line the catalog can contain a line like | |
531 | ||
532 | $ codeset=ISO-8859-2 | |
533 | ||
534 | to select the charset (ISO-8859-2 in this case). | |
535 | ||
536 | Implemented by Shinya Hanataka and Ulrich Drepper. | |
aea6353a UD |
537 | |
538 | * New codeset conversion modules: IBM-922 (Estonia PC codeset), | |
539 | IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). | |
540 | Contributed by Masahide Washizawa <washi@jp.ibm.com>. | |
234669e2 UD |
541 | |
542 | * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson | |
543 | <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. | |
544 | ||
545 | * The LANGUAGE environment variable is now ignored unless the locale is | |
546 | changed from the default "C" locale. | |
547 | ||
548 | * The usual bug fixes. | |
d2defdc4 | 549 | \f |
2e92188d UD |
550 | Version 2.2 |
551 | ||
08a2e4a0 GM |
552 | * Greg McGary added runtime support for bounds checking using gcc's |
553 | new -fbounded-pointers option. ix86 target is complete. PowerPC | |
554 | is in progress. | |
555 | ||
2e92188d UD |
556 | * Thorsten Kukuk added secure mode support to nscd. |
557 | ||
793bd4d9 | 558 | * The Berkeley db libraries have been removed. |
2e92188d | 559 | |
47b853e8 UD |
560 | Related, the nss_db module is now in a separate package since it |
561 | obviously requires a database library being available. | |
562 | ||
0013b2b1 UD |
563 | * Wide character I/O streams implemented by Ulrich Drepper. |
564 | ||
abbffdf9 | 565 | * Functions from the extended socket API added by Ulrich Drepper. |
01c771d0 | 566 | |
6e8afc1c UD |
567 | * Functions feenableexcept and fedisableexcept to control the |
568 | behaviour of individual exceptions have been added by Andreas Jaeger. | |
569 | ||
591e1ffb UD |
570 | * ldconfig program added by Andreas Jaeger and Jakub Jelinek. |
571 | ||
d3436b3c UD |
572 | * The resolver code has been updated from bind 8.2.3-T5B which supports |
573 | threads. The integration was done by Andreas Jaeger, Adam D. Bradley, | |
574 | and Mark Kettenis. | |
2588068b UD |
575 | |
576 | This change could in some situations effect backward compatibility. Since | |
577 | now `_res' is a thread-local instead of a global variable, modifying it | |
578 | in one thread does not have any effect in other threads. | |
66ac0abe | 579 | |
a00c3ca9 | 580 | The resolver library was also extended to allow IPv6 as the transport |
d3436b3c UD |
581 | protocol for the requests. This work was done by Stig Venaas. |
582 | ||
1c5d4617 UD |
583 | * Compatibility code for K&R C compilers has been removed from the |
584 | header files. A ISO C compiler is needed to use the library | |
585 | (conforming to either C89 or C99 standard). | |
586 | ||
abbffdf9 UD |
587 | * Complete rewrite of the localedef program to support multibyte character |
588 | sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, | |
589 | strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. | |
590 | Implemented by Ulrich Drepper. | |
591 | ||
8f3f1e09 UD |
592 | Bruno Haible significantly improved the generation and use of the data |
593 | structures for the wide character tables. | |
594 | ||
abbffdf9 UD |
595 | * Plural handling in gettext implemented by Ulrich Drepper. |
596 | ||
69173865 UD |
597 | * The utmp daemon has been removed. |
598 | ||
599 | * The port to MIPS-Linux has been finished by Andreas Jaeger. | |
600 | ||
37fb8add UD |
601 | * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima |
602 | and Yutaka Niibe. | |
603 | ||
594cee6c UD |
604 | * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. |
605 | ||
40c4c9b5 UD |
606 | * POSIX barriers implemented by Kaz Kylheku. |
607 | ||
594cee6c UD |
608 | * POSIX spawn function family implemented by Ulrich Drepper. |
609 | ||
610 | * POSIX spinlocks are now available. | |
611 | ||
40c4c9b5 UD |
612 | * Timed wait functions for mutex, rwlock, and semaphores are implemented. |
613 | ||
8f3f1e09 UD |
614 | * the configure option --enable-kernel=X.Y.Z allows to strip out |
615 | compatibility for kernel versions before X.Y.Z. This is currently only | |
616 | implemented for Linux. | |
617 | ||
3107c0c5 UD |
618 | * the sockaddr_in6 structure changed. The IPv6 working group added a new |
619 | field sin6_scope_id. This means that all programs using IPv6 should be | |
620 | recompiled. Don't expect binary compatibility with previous glibc | |
621 | versions. | |
622 | ||
d2830ba4 UD |
623 | * various conversion modules for IBM character sets contributed by |
624 | Masahide Washizawa. | |
625 | ||
8f3f1e09 UD |
626 | * IA-64 port by Jes Sorensen and HJ Lu. |

629 | Compiling the GNU C Library for Linux/ia64 | |
630 | ****************************************** | |
631 | ||
632 | Please refer to the file INSTALL in the same directory as you found | |
633 | this file for general information about configuring and compiling | |
634 | glibc. | |
635 | ||
636 | For general inquiries about glibc under Linux/ia64 please use the | |
637 | following mailing list linux-ia64@linuxia64.org or one of the relevant | |
638 | glibc mailing lists. | |
639 | ||
640 | Recommended Tools for Compilation | |
641 | ================================= | |
642 | ||
643 | In order for glibc-2.2 to build correctly on the ia64 you need at | |
644 | least the following versions of the GNU tools (the : | |
645 | ||
646 | * The Cygnus toolchain snapshot for the ia64 as of August 4 | |
aea6353a UD |
647 | including the provided set of patches. It is however recommend |
648 | you use the October 24 toolchain snapshot or a more recent version. | |
8f3f1e09 UD |
649 | |
650 | OR alternatively you can try the following (the Cygnus toolchain is | |
651 | the recommended solution): | |
652 | ||
653 | * GCC and binutils, GAS and GNU LD out of CVS from | |
aea6353a | 654 | sources.redhat.com as of August 28, 2000 or later. The CVS tree |
8f3f1e09 UD |
655 | may require special patches to work properly on the ia64. |
656 | ||
657 | Configuring and compiling GNU Libc for Linux/ia64 | |
658 | ================================================= | |
659 | ||
660 | The library requires Linux kernel version 2.4.0-test4-000728 or | |
aea6353a UD |
661 | later to funtion properly. Besides that it support for debug libraries |
662 | is currently untested. Hence the following options | |
8f3f1e09 UD |
663 | are required for configuring the library: |
664 | ||
aea6353a | 665 | --disable-debug --enable-kernel=2.4.0 |
8f3f1e09 UD |
666 | |
667 | It is also important that you make sure the library picks up the | |
668 | appropriate kernel header files, if you do not have recent enough | |
669 | kernel headers in /usr/src/linux/include, you should use the | |
670 | --with-headers=<path> option to specify the location. | |
671 | ||
672 | As an example I personally use the following options to configure | |
673 | the library: | |
674 | ||
675 | --disable-debug | |
8f3f1e09 UD |
676 | --disable-cvs |
677 | --enable-kernel=2.4.0 | |
678 | --host=ia64-linux | |
679 | --enable-add-ons=yes | |
680 | --prefix=/usr | |
681 | --with-headers=/home/jes/linux/include | |
682 | ||
683 | ||
684 | Good luck | |

e518937a UD |
700 | Version 2.1.1 |
701 | ||
27995311 UD |
702 | * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added. |
703 | ||
16b0f634 UD |
704 | * New xdr functions are added; some rpc functions are now 64bit clean. |
705 | ||
407d26b7 | 706 | * Fixed a number of bugs and memory leaks (especially in NIS+ code). |
16b0f634 UD |
707 | |
708 | * Fixed known incompatibilities with glibc 2.0. | |
709 | ||
407d26b7 | 710 | * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. |
16b0f634 | 711 | |
407d26b7 | 712 | * Optimized a number of functions (especially the ELF dynamic loader). |

27995311 | 715 | |
554b8800 UD |
716 | * lots of charmaps corrections |
717 | ||
718 | * some new locale definitions and charmaps | |

e518937a | 720 | \f |
c84142e8 UD |
721 | Version 2.1 |
722 | ||
da2d1bc5 UD |
723 | * Richard Henderson corrected size of struct timeval on Linux/Alpha to |
724 | conform to POSIX member type requirements. Symbol versions have been | |
725 | adjusted as needed within the library, and for direct use by applications, | |
726 | but there is potential for problems if third-party libraries use | |
727 | struct timeval as part of their interface. This does not present | |
728 | a problem for X and other "essential" system libraries. | |
729 | ||
c84142e8 | 730 | * An additional locale model to support C++ Standard Library locale |
1fb05e3d | 731 | model and probably more was implemented by Ulrich Drepper. |
c84142e8 | 732 | |
1fb05e3d | 733 | * Eric Youngdale and Ulrich Drepper implemented versioning of objects on |
c84142e8 UD |
734 | symbol level. |
735 | ||
736 | * Miles Bader provided the `argp' function family to support hierachical | |
737 | command line argument parsing, layered on top of getopt. | |
377a515b | 738 | |
cbdee279 | 739 | * strtod accepts new hexadecimal floating-point format from ISO C 9X. |
377a515b UD |
740 | |
741 | * printf has two new specifiers %a and %A to print hexadecimal flaoting-point | |
cbdee279 | 742 | numbers. |
377a515b | 743 | |
cbdee279 | 744 | * scanf recognizes the %a and %A format for scanning floating point numbers. |
e61abf83 | 745 | |
48869012 UD |
746 | * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides |
747 | information and interfaces for the available integer types. | |
e61abf83 | 748 | |
813f4f4d UD |
749 | * about 130 new math functions were added to implement the ISO C9x math |
750 | library. | |

e61abf83 | 752 | * the new header <complex.h> contains definitions of the complex math |
cbdee279 UD |
753 | functions from ISO C 9X. |

40a4b79f | 1196 | Version 2.0 |
28f540f4 | 1197 | |
d3669add RM |
1198 | * GNU extensions are no longer declared by default. To enable them you |
1199 | must define the macro `_GNU_SOURCE' in your program or compile with | |
1200 | `-D_GNU_SOURCE'. | |
1201 | ||
28f540f4 RM |
1202 | * The library has changed from using GNU ld symbol aliases to using weak |
1203 | symbols where available. The ELF object file format supports weak | |
1204 | symbols; GNU ld also supports weak symbols in the a.out format. (There | |
1205 | is also now support for other GNU ld extensions in ELF. Use the | |
787126fe RM |
1206 | `--with-elf' option to configure to indicate you have ELF, and |
1207 | `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion | |
28f540f4 RM |
1208 | of many files which contained only symbol aliases, reducing the size of |
1209 | the source and the compiled library; many other files were renamed to | |
1210 | less cryptic names previously occupied by the symbol alias files. | |
dcf0671d UD |
1211 | There is a new header file <elf.h> for programs which operate on |
1212 | files in the ELF format. | |
49e522bf RM |
1213 | |
1214 | * Converted to Autoconf version 2, so `configure' has more options. | |
1215 | Run `configure --help' to see the details. | |
1216 | ||
1217 | * The library can now be configured to build profiling, highly-optimized | |
b25c5d66 RM |
1218 | (but undebuggable), and/or shared libraries (ELF with GNU ld only). The |
1219 | `--enable-profile', `--enable-omitfp', and `--enable-shared' options to | |
1220 | `configure' enable building these extra libraries. The shared library is | |
1221 | built by default when using both ELF and GNU ld. When shared libraries | |
1222 | are enabled, the new library `-ldl' is available for arbitrary run-time | |
1223 | loading of shared objects; its interface is defined in <dlfcn.h>. The | |
1224 | new header file <link.h> gives access to the internals of the run-time | |
33a934a3 UD |
1225 | dynamic linker, `ld.so'. The shell script `ldd' is similar to the |
1226 | application of same name on other systems and it provides information | |
1227 | about dynamically linked binaries. | |
49e522bf | 1228 | |
71733723 RM |
1229 | * The C library now provides the run-time support code for profiling |
1230 | executables compiled with `-pg'. Programs can control the profiling code | |
d3669add RM |
1231 | through the interface in <sys/gmon.h>. The `gmon.out' files written by |
1232 | the GNU C library can be read only by GNU `gprof' (from GNU binutils); | |
1233 | the support for this file format was contributed by David Mosberger-Tang. | |
71733723 | 1234 | |
f7eac6eb | 1235 | * The math code has been replaced with a math library based on fdlibm from |
33a934a3 UD |
1236 | Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by |
1237 | Ian Taylor with `float' functions and by Ulrich Drepper with `long double' | |
1238 | functions. The math functions now reside in a separate library, so | |
1239 | programs using them will need to use `-lm' their linking commands. | |
1240 | ||
1241 | * John C. Bowman contributed optimized ix87 assembler inline functions. | |
f7eac6eb | 1242 | |
5f0e6fc7 RM |
1243 | * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' |
1244 | mechanism similar to that found in Solaris 2. This is now used for the | |
33a934a3 UD |
1245 | group, passwd, hosts, networks, services, protocols, rpc, ethers, |
1246 | shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' | |
1247 | file controls what services are used for each individual database. This | |
1248 | works by loading shared libraries with names specified in `nsswitch.conf', | |
1249 | so service modules can be changed or added at any time without even | |
1250 | relinking any program. Currently there are the file, db, and NIS based | |
1251 | NSS services available. | |
5f0e6fc7 | 1252 | |
49e522bf RM |
1253 | * The new functions `strtoq' and `strtouq' parse integer values from |
1254 | strings, like `strtol' and `strtoul', but they return `long long int' and | |
1255 | `unsigned long long int' values, respectively (64-bit quantities). | |
1256 | ||
1257 | * The new functions `strtof' and `strtold' parse floating-point values from | |
1258 | strings, like `strtod', but they return `float' and `long double' values, | |
1259 | respectively (on some machines `double' and `long double' are the same). | |
1260 | ||
1261 | * Ulrich Drepper has contributed new implementations of the floating-point | |
1262 | printing and reading code used in the `printf' family of functions and | |
1263 | `strtod', `strtof', and `strtold'. These new functions are perfectly | |
1264 | accurate, and much faster than the old ones. | |
1265 | ||
33a934a3 UD |
1266 | * The implementation of the POSIX locale model was completely rewritten by |
1267 | Ulrich Drepper. This includes the new programs `localedef' and `locale' | |
1268 | to compile the POSIX locale definition. | |
1269 | ||
1270 | * The former dummy implementations of the strcoll and strxfrm function are | |
1271 | now replaced by fully functional code contributed by Ulrich Drepper. The | |
1272 | collation information comes from the POSIX locale definitions. | |
1273 | ||
49e522bf RM |
1274 | * The new header <langinfo.h> defines an interface for accessing |
1275 | various locale-dependent data (using the locale chosen with `setlocale'). | |
1276 | ||
f7eac6eb | 1277 | * Ulrich Drepper has contributed a new suite of functions for operation on |
33a934a3 | 1278 | wide-character and multibyte-character strings, in <wchar.h>; |
b7407d63 | 1279 | and classification and case conversion of wide characters, in <wctype.h>. |
33a934a3 UD |
1280 | These new functions are conforming to the ISO C, Amendement 1 specification. |
1281 | ||
1282 | * There is now a second implementation of the standard I/O library available. | |
1283 | It comes from GNU libg++ as was written by Per Bothner, heavily modified | |
1284 | by Hongjiu Lu and made thread safe by Ulrich Drepper. | |
f7eac6eb | 1285 | |
71733723 | 1286 | * You can now use positional parameter specifications in format strings |
49e522bf RM |
1287 | for the `printf' and `scanf' families of functions. For example, |
1288 | `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints | |
1289 | ``Number 6, Mr Jones''. This is mainly useful when providing different | |
d365fd2c RM |
1290 | format strings for different languages, whose grammars may dictate |
1291 | different orderings of the values being printed. To support this | |
49e522bf | 1292 | feature, the interface for `register_printf_handler' has changed; see |
d365fd2c | 1293 | the header file <printf.h> for details. |
49e522bf RM |
1294 | |
1295 | * The `printf' and `scanf' families of functions now understand a new | |
1296 | formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says | |
1297 | to group numbers as indicated by the locale; for `scanf' and friends, this | |
1298 | says to accept as valid only a number with all the proper grouping | |
1299 | separators in the right places. In the default "C" locale, numbers are | |
1300 | not grouped; but locales for specific countries will define the usual | |
1301 | conventions (i.e. separate thousands with `,' in the US locale). | |
28f540f4 RM |
1302 | |
1303 | * The pgrp functions have been regularized, slightly incompatibly but much | |
1304 | less confusingly. The core functions are now `getpgid' and `setpgid', | |
1305 | which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no | |
1306 | argument) and BSD `setpgrp' (identical to `setpgid') functions are | |
1307 | provided for compatibility. There is no longer an incompatible `getpgrp' | |
1308 | with an argument declared under _BSD_SOURCE; no BSD code uses it. | |
1309 | ||
1310 | * The new header file <fts.h> and suite of functions simplify programs that | |
1311 | operate on directory trees. This code comes from 4.4 BSD. | |
1312 | ||
33a934a3 UD |
1313 | * The resolver code has been updated from the BIND 4.9.5-P1 release. |
1314 | Parts of the code were heavily modified by Ulrich Drepper to fit in the | |
1315 | NSS scheme used in glibc. | |
28f540f4 | 1316 | |
28f540f4 RM |
1317 | * There is a new malloc debugging hook `__memalign_hook'. |
1318 | ||
1319 | * There are new typedefs `ushort' for `unsigned short int' and `uint' for | |
1320 | `unsigned int' in <sys/types.h>. These are for compatibility only and | |
1321 | their use is discouraged. | |
1322 | ||
1323 | * The `-lmcheck' library to enable standard malloc debugging hooks is now | |
1324 | done differently, so that it works even without GNU ld. | |
787126fe | 1325 | |
22a1292a RM |
1326 | * New function `euidaccess' checks allowed access to a file like `access', |
1327 | but using the effective IDs instead of the real IDs. | |
49e522bf RM |
1328 | |
1329 | * The time zone data files have been updated for the latest and greatest | |
1330 | local time conventions of the countries of the world. | |
1331 | ||
1332 | * The new function `dirfd' extracts the file descriptor used by a DIR stream; | |
1333 | see <dirent.h>. | |
1334 | ||
1335 | * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface | |
1336 | for formatting floating-point numbers. They are provided only for | |
33a934a3 UD |
1337 | compatibility; new programs should use `sprintf' instead. There are |
1338 | also equivalent function for the `long double' floating-point type and | |
1339 | all functions also exist in a reentrant form. | |
342414a6 RM |
1340 | |
1341 | * The new auxiliary library `-lutil' from 4.4 BSD contains various | |
1342 | functions for maintaining the login-record files (primarily of use to | |
1343 | system programs such as `login'), and convenient functions for | |
1344 | allocating and initializing a pseudo-terminal (pty) device. | |
c709e372 RM |
1345 | |
1346 | * Ulrich Drepper has contributed new support for System V style | |
1347 | shared memory and IPC on systems that support it. | |
1348 | ||
1349 | * Ulrich Drepper has contributed several miscellaneous new functions found | |
1350 | in System V: The `hsearch' family of functions provide an effective | |
1351 | implementation of hash tables; `a64l' and `l64a' provide a very simple | |
1352 | binary to ASCII mapping; `drand48' and friends provide a 48-bit random | |
1353 | number generator. | |
1354 | ||
1355 | * Ulrich Drepper has contributed new reentrant counterparts for the | |
1356 | `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. | |
1357 | ||
1358 | * Ulrich Drepper has contributed new, highly-optimized versions of several | |
1359 | string functions for the i486/Pentium family of processors. | |
1360 | ||
71733723 | 1361 | * Ulrich Drepper has updated the Linux-specific code, based largely |
c709e372 | 1362 | on work done in Hongjiu Lu's version of GNU libc for Linux. |
33a934a3 UD |
1363 | The GNU library now supports Linux versions 2.0.10 and later, |
1364 | using the ELF object file format (i[3456]86-*-linux). | |
c709e372 | 1365 | |
d3669add RM |
1366 | * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). |
1367 | ||
33a934a3 UD |
1368 | * David Mosberger-Tang and Richard Henderson have ported the C library |
1369 | to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the | |
1370 | dynamic linking support for ELF/Alpha. | |
1371 | ||
1372 | * Richard Henderson contributed several Alpha optimized assembler function | |
1373 | for arithmetic and string handling. | |
d3669add | 1374 | |
c709e372 | 1375 | * Ulrich Drepper has contributed a new set of message catalog functions to |
40a4b79f RM |
1376 | support multiple languages using the <libintl.h> interface, for use with |
1377 | his new package GNU gettext. Translation volunteers have contributed | |
1378 | catalogs of the library's messages in Spanish, German, and Korean. | |
1379 | ||
1380 | * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' | |
1381 | program and the `catgets' function for reading the catalog files it | |
1382 | creates. (The <libintl.h> interface is preferred; we include the | |
1383 | <nl_types.h> interface using `catgets' only for source compatibility with | |
1384 | programs already written to use it.) | |
71733723 RM |
1385 | |
1386 | * New header file <values.h> gives SVID-compatible names for <limits.h> | |
1387 | constants. | |
1388 | ||
1389 | * Various new macros, declarations, and small header files for compatibility | |
1390 | with 4.4 BSD. | |
1391 | ||
1392 | * New function `group_member' is a convenient way to check if a process has | |
1393 | a given effective group ID. | |
1394 | ||
1395 | * When using GCC 2.7 and later, the socket functions are now declared in a | |
1396 | special way so that passing an argument of type `struct sockaddr_in *', | |
1397 | `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic | |
1398 | `struct sockaddr *' type, does not generate a type-clash warning. | |
1399 | ||
1400 | * New function `error' declared in header file <error.h> is a convenient | |
6d52618b | 1401 | function for printing error messages and optionally exiting; this is the |
71733723 RM |
1402 | canonical function used in GNU programs. The new functions `err', `warn', |
1403 | and friends in header file <err.h> are the canonical 4.4 BSD interface for | |
1404 | doing the same thing. | |
1405 | ||
1406 | * The <glob.h> interface has several new flags from 4.4 BSD that extend the | |
1407 | POSIX.2 `glob' function to do ~ and {...} expansion. | |
1408 | ||
1409 | * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. | |
33a934a3 | 1410 | `clearenv' which is used in POSIX.9 is also available. |
71733723 RM |
1411 | |
1412 | * New function `getsid' returns session ID number on systems that support it. | |
1413 | ||
f7eac6eb RM |
1414 | * We have incorporated the 4.4 BSD `db' library (version 1.85). New header |
1415 | files <db.h> and <mpool.h> provide a rich set of functions for several | |
1416 | types of simple databases stored in memory and in files, and <ndbm.h> is | |
6d52618b | 1417 | an old `ndbm'-compatible interface using the `db' functions. Link with |
999493cb | 1418 | `-ldb' to get these functions. |
f7eac6eb RM |
1419 | |
1420 | * New macro `strdupa' copies a string like `strdup', but uses local stack | |
1421 | space from `alloca' instead of dynamic heap space from `malloc'. | |
52e9a9d1 RM |
1422 | |
1423 | * New function `strnlen' is like `strlen' but searches only a given maximum | |
33a934a3 UD |
1424 | number of characters for the null terminator. `stpncpy', `strndup' and |
1425 | `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' | |
1426 | function. | |
40a4b79f RM |
1427 | |
1428 | * New function `statfs' in header <sys/statfs.h>. | |
1429 | ||
1430 | * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader | |
1431 | provide convenient functions for operating on blocks of null-terminated | |
1432 | strings. | |
1433 | ||
1434 | * A new suite of functions in <utmp.h> handle all the details of reading | |
1435 | and writing the utmp file. | |
33a934a3 UD |
1436 | |
1437 | * An implementation of the NIS/YP(tm) based NSS service was contributed by | |
1438 | Thorsten Kukuk. | |
1439 | ||
1440 | * Paul Eggert and Ulrich Drepper modified the `strftime' function to be | |
1441 | completely POSIX compliant and also implemented the extended functionality | |
1442 | to handle alternate digit representation and alternate era date formats. | |
1443 | ||
1444 | * Ulrich Drepper provided an implementation of the `strptime' function | |
1445 | defined in XPG4.2 which transforms a string into a `struct tm' value. | |
1446 | ||
1447 | * Paul Eggert provided the tzselect shell script as part of the timezone | |
1448 | code. The shell script makes it easy to select the correct timezone | |
1449 | specification. | |
1450 | ||
1451 | * The implementation of the malloc family of functions is completely replaced | |
1452 | by a new implementation by Doug Lea with many improvements by Wolfram Gloger. | |
1453 | The implementation uses the mmap function (if available) and it is | |
1454 | optimized for the use in multi threaded programs. | |
1455 | ||
1456 | * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of | |
1457 | functions. This new functionality is usable by specifying a special | |
1458 | salt string and it is compatible with implementation on *BSD systems. | |
1459 | ||
1460 | * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: | |
1461 | `getsubopt' to handle second level command line options, `bsd_signal' | |
1462 | to access BSD style `signal' functionality, the obsolete `regexp' style | |
1463 | expression matcher. | |
1464 | ||
1465 | * the `lchown' function is available on system which support this | |
1466 | functionality. | |
1467 | ||
1468 | * The implementation of the shadow password handling function was contributed | |
1469 | by Ulrich Drepper. | |
1470 | ||
1471 | * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. | |
1472 | ||
1473 | * POSIX.1g support was added. The <sys/select.h> header is available, | |
1474 | `isfdtype' and `pselect' are implemented. Craig Metz contributed an | |
1475 | implementation of `getaddrinfo'. | |
28f540f4 RM |
1476 | \f |
1477 | Version 1.09 | |
1478 | ||
1479 | * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. | |
1480 | ||
1481 | * New header file <fstab.h> and new functions `getfsspec', `getfsent' and | |
1482 | friends, for parsing /etc/fstab. This code comes from 4.4 BSD. | |
1483 | ||
1484 | * The new function `daemon' from 4.4 BSD is useful for server programs that | |
1485 | want to put themselves in the background. | |
1486 | ||
1487 | * Joel Sherrill has contributed support for several standalone boards that | |
1488 | run without an operating system. | |
1489 | ||
1490 | * `printf', `scanf' and friends now accept a `q' type modifier for long | |
1491 | long int as well as `ll'. Formats using these might be `%qu' or `%lld'. | |
1492 | ||
1493 | * All of the code taken from BSD (notably most of the math and networking | |
1494 | routines) has been updated from the BSD 4.4-Lite release. | |
1495 | ||
1496 | * The resolver code has been updated from the BIND-4.9.3-BETA9 release. | |
1497 | ||
1498 | * The new functions `getdomainname' and `setdomainname' fetch or change the | |
1499 | YP/NIS domain name. These are system calls which exist on systems which | |
1500 | have YP (aka NIS). | |
1501 | ||
1502 | * The time zone data files have been updated for the latest international | |
1503 | conventions. | |
1504 | ||
1505 | * The SunRPC programs `portmap' and `rpcinfo' are now installed in | |
1506 | $(sbindir) (usually /usr/local/sbin) instead of $(bindir). | |
1507 | \f | |
1508 | Version 1.08 | |
1509 | ||
1510 | * The C library now includes support for Sun RPC, from Sun's free | |
1511 | RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs | |
1512 | are included. (There is still no support for YP.) | |
1513 | ||
1514 | * Tom Quinn has contributed a port of the C library to SGI machines running | |
1515 | Irix 4 (mips-sgi-irix4). | |
1516 | ||
1517 | * The new `lockf' function is a simplified interface to the locking | |
1518 | facilities of `fcntl', included for compatibility. | |
1519 | ||
1520 | * New time functions `timegm', `timelocal', and `dysize' for compatibility. | |
1521 | ||
1522 | * New header file <sys/timeb.h> and new function `ftime' for compatibility. | |
1523 | ||
1524 | * New header files <poll.h> and <sys/poll.h> and new function `poll' for | |
1525 | compatibility. | |
1526 | ||
1527 | * The error message printed by `assert' for a failed assertion now includes | |
1528 | the name of the program (if using GNU ld) and the name of the calling | |
1529 | function (with versions of GCC that support this). | |
1530 | ||
1531 | * The `psignal' function is now declared in <signal.h>, not <stdio.h>. | |
1532 | ||
1533 | * The library now includes the <sys/mman.h> header file and memory | |
1534 | management functions `mmap', `munmap', `mprotect', `msync', and | |
1535 | `madvise', on systems that support those facilities. | |
1536 | ||
1537 | * The interface for `mcheck' has changed slightly: the function called to | |
1538 | abort the program when an allocation inconsistency is detected now takes | |
1539 | an argument that indicates the type of failure. The new function | |
1540 | `mprobe' lets you request a consistency check for a particular block at | |
1541 | any time (checks are normally done only when you call `free' or `realloc' | |
1542 | on a block). | |
1543 | ||
1544 | * It is now possible to easily cross-compile the C library, building on one | |
1545 | system a library to run on another machine and/or operating system. All | |
1546 | you need to do is set the variable `HOST_CC' in `configparms' to the | |
1547 | native compiler for programs to run on the machine you are building on (a | |
1548 | few generator programs are used on Unix systems); set `CC' to the | |
1549 | cross-compiler. | |
1550 | ||
1551 | * The new function `fexecve' (only implemented on the GNU system) executes | |
1552 | a program file given a file descriptor already open on the file. | |
1553 | \f | |
1554 | Version 1.07 | |
1555 | ||
1556 | * Brendan Kehoe has contributed most of a port to the DEC Alpha | |
1557 | running OSF/1 (alpha-dec-osf1). He says it is 75% complete. | |
1558 | ||
1559 | * You can set the variable `libprefix' in `configparms' to specify a prefix | |
1560 | to be prepended to installed library files; this makes it easy to install | |
1561 | the GNU C library to be linked as `-lgnuc' or whatever. | |
1562 | ||
1563 | * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It | |
1564 | copies a limited number of characters from a string, and returns the | |
1565 | address of the last character written. | |
1566 | ||
1567 | * You no longer need to check for whether the installed `stddef.h' is | |
1568 | compatible with the GNU C library. configure now checks for you. | |
1569 | ||
1570 | * You can now define a per-stream `fileno' function to convert the | |
1571 | stream's cookie into an integral file descriptor. | |
1572 | ||
1573 | * ``malloc (0)'' no longer returns a null pointer. Instead, it | |
1574 | allocates zero bytes of storage, and returns a unique pointer which | |
1575 | you can pass to `realloc' or `free'. The behavior is undefined if | |
1576 | you dereference this pointer. | |
1577 | ||
1578 | * The C library now runs on Sony NEWS m68k machines running either | |
1579 | NewsOS 3 or NewsOS 4. | |
1580 | ||
1581 | * The new `syscall' function is a system-dependent primitive function | |
1582 | for invoking system calls. It has the canonical behavior on Unix | |
1583 | systems, including unreliable return values for some calls (such as | |
1584 | `pipe', `fork' and `getppid'). | |
1585 | ||
1586 | * The error code `EWOULDBLOCK' is now obsolete; it is always defined | |
1587 | to `EAGAIN', which is the preferred name. On systems whose kernels | |
1588 | use two distinct codes, the C library now translates EWOULDBLOCK to | |
1589 | EAGAIN in every system call function. | |
1590 | \f | |
1591 | Version 1.06 | |
1592 | ||
1593 | * The GNU C Library Reference Manual is now distributed with the library. | |
1594 | `make dvi' will produce a DVI file of the printed manual. | |
1595 | `make info' will produce Info files that you can read on line using C-h i | |
1596 | in Emacs or the `info' program. | |
ea278354 | 1597 | Please send comments on the manual to bug-glibc-manual@gnu.org. |
28f540f4 RM |
1598 | |
1599 | * The library now supports SVR4 on i386s (i386-unknown-sysv4). | |
1600 | ||
1601 | * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. | |
1602 | ||
1603 | * Jason Merrill has contributed a port to the Sequent Symmetry running | |
1604 | Dynix version 3 (i386-sequent-dynix). | |
1605 | ||
1606 | * The library has been ported to i386s running SCO 3.2.4 (also known as SCO | |
1607 | ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). | |
1608 | ||
1609 | * New function `memory_warnings' lets you arrange to get warnings when | |
1610 | malloc is running out of memory to allocate, like Emacs gives you. | |
1611 | ||
1612 | * The C library now contains the relocating allocator used in Emacs 19 for | |
1613 | its editing buffers. This allocator (ralloc) minimizes allocation | |
1614 | overhead and fragmentation by moving allocated regions around whenever it | |
1615 | needs to. You always refer to a ralloc'd region with a "handle" (a | |
1616 | pointer to a pointer--an object of type `void **'). | |
1617 | ||
1618 | * There is a new `printf' format: `%m' gives you the string corresponding | |
1619 | to the error code in `errno'. | |
1620 | ||
1621 | * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' | |
1622 | or `%[' conversion, but instead of filling in a fixed-sized buffer you | |
1623 | pass, the `a' modifier says to fill in a `char **' you pass with a | |
1624 | malloc'd string. | |
1625 | ||
1626 | * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and | |
1627 | `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a | |
1628 | name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. | |
1629 | ||
1630 | * `mkstemp' is a traditional Unix function to atomically create and open a | |
1631 | uniquely-named temporary file. | |
1632 | \f | |
1633 | Version 1.05 | |
1634 | ||
1635 | * The standard location for the file that says what the local timezone is | |
1636 | has changed again. It is now `/usr/local/etc/localtime' (or more | |
1637 | precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. | |
1638 | ||
1639 | * The distribution no longer contains any files with names longer than 14 | |
1640 | characters. | |
1641 | ||
1642 | * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. | |
1643 | These are set by the new `trusted' and `console' keywords in `/etc/ttys'. | |
1644 | ||
1645 | * New functions `ttyslot' and `syslog' from 4.4 BSD. | |
1646 | \f | |
1647 | Version 1.04 | |
1648 | ||
1649 | * The configuration process has changed quite a bit. The `configure' | |
1650 | script is now used just like the configuration scripts for other GNU | |
1651 | packages. The `sysdeps' directory hierarchy is much rearranged. | |
1652 | The file `INSTALL' explains the new scheme in detail. | |
1653 | ||
1654 | * The header files no longer need to be processed into ANSI C and | |
1655 | traditional C versions. There is just one set of files to install, and | |
1656 | it will work with ANSI or old C compilers (including `gcc -traditional'). | |
1657 | ||
1658 | * Brendan Kehoe and Ian Lance Taylor have ported the library to the | |
1659 | MIPS DECStation running Ultrix 4. | |
1660 | ||
1661 | * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. | |
1662 | Tom Quinn contributed the initial code. The GNU C library can NOT yet be | |
1663 | made itself into a shared library. | |
1664 | ||
1665 | * Yet further improved support for the i386, running 4.3 BSD-like systems | |
1666 | (such as Mach 3 with the Unix single-server), or System V. | |
1667 | ||
1668 | * New function `strncasecmp' to do case-insensitive string comparison | |
1669 | with limited length. | |
1670 | ||
1671 | * New function `strsep' is a reentrant alternative to `strtok'. | |
1672 | ||
1673 | * New functions `scandir' and `alphasort' for searching directories. | |
1674 | ||
1675 | * New function `setenv' is a better interface to `putenv'. | |
1676 | ||
1677 | * Ian Lance Taylor has contributed an implementation of the SVID `ftw' | |
1678 | function for traversing a directory tree. | |
1679 | ||
1680 | * The GNU obstack package is now also part of the C library. | |
1681 | The new function `open_obstack_stream' creates a stdio stream that | |
1682 | writes onto an obstack; `obstack_printf' and `obstack_vprintf' do | |
1683 | formatted output directly to an obstack. | |
1684 | ||
1685 | * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), | |
1686 | cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. | |
1687 | ||
1688 | * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. | |
1689 | ||
1690 | * The new functions `strfry' and `memfrob' do mysterious and wonderful | |
1691 | things to your strings. | |
1692 | ||
1693 | * There are some new test programs: test-fseek, testmb, and testrand. | |
1694 | ||
1695 | * Some work has been done to begin porting the library to 4.4 BSD and Linux. | |
1696 | These ports are not finished, but are a good starting place for really | |
1697 | supporting those systems. | |
1698 | ||
1699 | * `/etc/localtime' is now the standard location for the file that says what | |
1700 | the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. | |
1701 | This follows the general principle that `/etc' is the place for all local | |
1702 | configuration files. | |
1703 | ||
1704 | * The C library header files now use `extern "C"' when used by the C++ | |
1705 | compiler, so the C library should now work with C++ code. | |
1706 | ||
1707 | * The header file <bstring.h> is gone. <string.h> now declares bcopy, | |
56ddf355 UD |
1708 | bcmp, bzero, and ffs. (Update: nowadays these functions are declared |
1709 | in <strings.h>.) | |
28f540f4 RM |
1710 | |
1711 | * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting | |
1712 | function which uses the `merge sort' algorithm, and is said to be | |
1713 | significantly faster than the old GNU `qsort' function. Merge sort is | |
1714 | now the standard `qsort' function. The new algorithm can require a lot | |
1715 | of temporary storage; so, the old sorting function is called when the | |
1716 | required storage is not available. | |
1717 | ||
1718 | * The C library now includes Michael Glad's Ultra Fast Crypt, which | |
1719 | provides the Unix `crypt' function, plus some other entry points. | |
28f540f4 RM |
1720 | |
1721 | * The code and header files taken from 4.4 BSD have been updated with the | |
1722 | latest files released from Berkeley. | |
