28 | 14064, 14080, 14083 | |
29 | ||
30 | * ISO C11 support: | |
31 | ||
32 | + define static_assert | |
33 | ||
34 | + do not declare gets | |
35 | ||
36 | + declare at_quick_exit and quick_exit also for ISO C11 | |
37 | ||
38 | + aligned_alloc. NB: The code is deliberately allows the size parameter | |
39 | to not be a multiple of the alignment. This is a moronic requirement | |
40 | in the standard but it is only a requirement on the caller, not the | |
41 | implementation. | |
42 | ||
43 | + timespec_get added | |
44 | ||
45 | + uchar.h support added | |
46 | ||
47 | + CMPLX, CMPLXF, CMPLXL added | |
48 | ||
49 | Implemented by Ulrich Drepper. | |
50 | ||
51 | * Support for the IA-64 is removed and could live in ports. | |
52 | ||
53 | * Remove support for anything but ELF binary format | |
54 | ||
55 | * Checking versions of poll, ppoll added. | |
56 | Implemented by Ulrich Drepper. | |
57 | ||
58 | * More generic and 64-bit performance optimizations to math functions. | |
59 | Implemented by Ulrich Drepper. | |
60 | ||
61 | * New configure option --enable-obsolete-rpc makes the deprecated RPC | |
62 | headers and functions available at compile time as they were before | |
63 | version 2.14. This option will be removed at some time in the future | |
64 | after the TI-RPC library becomes fully sufficient for the needs of | |
65 | existing applications. | |
66 | \f | |

130 | \f | |
131 | Version 2.14 | |
132 | ||
133 | * The following bugs are resolved with this release: | |
134 | ||
135 | 386, 6420, 7101, 9730, 9732, 9809, 10138, 10149, 10157, 11099, 11257, | |

137 | 11781, 11799, 11820, 11837, 11857, 11869, 11892, 11895, 11901, 11945, | |
138 | 11947, 11952, 11987, 12052, 12083, 12158, 12178, 12200, 12346, 12350, | |
139 | 12393, 12420, 12432, 12445, 12449, 12453, 12454, 12460, 12469, 12489, | |
140 | 12509, 12510, 12511, 12518, 12527, 12541, 12545, 12551, 12582, 12583, | |
141 | 12587, 12597, 12601, 12611, 12625, 12626, 12631, 12650, 12653, 12655, | |
142 | 12660, 12671, 12681, 12684, 12685, 12711, 12713, 12714, 12717, 12723, | |

144 | 12795, 12811, 12813, 12814, 12841 | |
145 | ||
146 | * The RPC implementation in libc is obsoleted. Old programs keep working | |
147 | but new programs cannot be linked with the routines in libc anymore. | |
148 | Programs in need of RPC functionality must be linked against TI-RPC. | |
149 | The TI-RPC implementation is IPv6 enabled and there are other benefits. | |
150 | ||
151 | Visible changes of this change include (obviously) the inability to link | |
152 | programs using RPC functions without referencing the TI-RPC library and the | |
153 | removal of the RPC headers from the glibc headers. | |
154 | Implemented by Ulrich Drepper. | |
155 | ||
156 | * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at, | |
157 | syncfs, setns, sendmmsg | |
158 | ||
159 | * New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH, | |
160 | yue_HK, lij_IT, mhr_RU | |
161 | ||
162 | * New encodings: CP770, CP771, CP772, CP773, CP774 | |
163 | ||
164 | * New program sotruss to trace calls through PLTs | |
165 | Implemented by Ulrich Drepper. | |
166 | ||
167 | * The malloc hook implementation is marked deprecated and will be removed | |
168 | from the default implementation in the next version. The design never | |
169 | worked ever since the introduction of threads. Even programs which do | |
170 | not create threads themselves can use multiple threads created internally. | |
171 | \f | |
172 | Version 2.13 | |
173 | ||
174 | * The following bugs are resolved with this release: | |
175 | ||
176 | 3268, 6812, 7066, 10085, 10484, 10563, 10851, 11149, 11155, 11577, 11611, | |

183 | ||
184 | * POWER7 optimizations: memset, memcmp, strncmp | |
185 | ||
186 | * New optimized string functions for x86-64: strnlen (SSE2), | |
187 | strcasecmp (SSE2, SSSE3, SSE4.2), strncasecmp (SSE2, SSSE3, SSE4.2) | |
188 | Implemented by Ulrich Drepper. | |
189 | \f | |

197 | 11115, 11120, 11125, 11126, 11127, 11134, 11141, 11149, 11183, 11184, | |
198 | 11185, 11186, 11187, 11188, 11189, 11190, 11191, 11192, 11193, 11194, | |
199 | 11200, 11230, 11235, 11242, 11254, 11258, 11271, 11272, 11276, 11279, | |

202 | ||
203 | * New interfaces: pthread_getname_np, pthread_setname_np | |
204 | ||
205 | * New Linux interface: recvmmsg | |
206 | ||
207 | * STT_GNU_IFUNC implemented for Sparc by David Miller. | |
208 | ||
209 | * The dynamic linker now recognizes supported ABI versions from the | |
210 | EI_ABIVERSION field in the ELF header. | |
211 | Implemented by Ulrich Drepper. | |
212 | ||
213 | * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table | |
214 | will not be used to fill in password fields in the passwd.byname replies. | |
215 | Instead it is used to synthesize the shadow.byname table, should it be | |
216 | missing. This is a useful mode in some installations involving Solaris. | |
217 | Implemented by Ulrich Drepper. | |
218 | ||
219 | * New locales: kok_IN, sq_MK, cv_RU | |
220 | \f | |

229 | 10609, 10643, 10692, 10713, 10717, 10730, 10731, 10742, 10780, 10784, | |
230 | 10789, 10817, 10823, 10840, 10847 | |
231 | ||
232 | * New interfaces: execvpe, pthread_sigqueue, mkstemps, mkstemps64, mkostemps, | |
233 | mkostemps64 | |
234 | Implemented by Ulrich Drepper. | |
235 | ||
236 | * Checking version of longjmp added that fails if an uninitialized stack | |
237 | frame would be created. Implemented by Ulrich Drepper. | |
238 | ||
239 | * STT_GNU_IFUNC is now supported in static executables. | |
240 | Implemented by H.J. Lu. | |
241 | ||
242 | * STT_GNU_IFUNC implemented for PPC by Alan Modra. | |
243 | ||
244 | * New optimized string functions for x86-64: strstr, strcasestr, memcmp, | |
245 | strcspn, strpbrk, strspn, strcpy, stpcpy, strncpy, strcmp (SSE2, SSE4.2), | |
246 | strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2). | |
247 | Contributed by H.J. Lu. | |
248 | ||
249 | strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3). | |
250 | Implemented by Ulrich Drepper. | |
251 | ||
252 | * New optimized string functions for x86: strlen, strcspn, strspn, strpbrk, | |
253 | strstr, strcasestr. | |
254 | Contributed by H.J. Lu. | |
255 | ||
256 | * Support for fma instruction in AVX on x86-64. | |

263 | Implemented by Ulrich Drepper. | |
264 | ||
265 | * Implement second fallback mode for optimized DNS lookup for even more | |
266 | broken environments. If two requests from the same port are not | |
267 | handled correctly close the socket and open a new one before sending | |
268 | the second request. The 'single-request-reopen' option in /etc/resolv.conf | |
269 | can be used to select this mode right away, instead of rediscovering the | |
270 | necessity is every process again. | |
271 | Implemented by Ulrich Drepper. | |
272 | ||
273 | * New resolver flag RES_USE_DNSSEC to enable use of verified lookup. | |
274 | Implemented by Adam Tkac. | |
275 | ||
276 | * Optimized iconv conversions for S390x. | |
277 | Implemented by Andreas Krebbel. | |

295 | * New interfaces: preadv, preadv64, pwritev, pwritev64, malloc_info | |
296 | Implemented by Ulrich Drepper. | |
297 | ||
298 | * New Linux interfaces: accept4, fallocate, fallocate64. | |
299 | Implemented by Ulrich Drepper. | |
300 | ||
301 | * Correct declarations of string function when used in C++ code. This | |
302 | could lead to compile errors for invalid C++ code. | |
303 | ||
304 | * XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are | |
305 | now in POSIX. | |
306 | ||
307 | * New POSIX 2008 interface: psiginfo | |
308 | Implemented by Ulrich Drepper. | |
309 | ||
310 | * New ISO C++1x interfaces: quick_exit, at_quick_exit | |
311 | Implemented by Ulrich Drepper. | |
312 | ||
313 | * Support for selecting between multiple function definitions at runtime | |
314 | using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper. | |
315 | ||
316 | * The libcrypt library can now use the hash function implementations in | |
317 | NSS. Implemented by Ulrich Drepper. | |
318 | ||
319 | * The malloc implementation can be compiled to be less memory efficient | |
320 | but higher performing in multi-threaded programs. | |
321 | Implemented by Ulrich Drepper. | |
322 | ||
323 | * New locales: nan_TW@latin, ks_IN | |

336 | servers (the case, e.g., for some people using the built-in DNS | |
337 | server in ADSL modems/routers). There is a once-per-process timeout | |
338 | in case of a broken server. To avoid it, users can run nscd or put | |
339 | 'options single-request' in /etc/resolv.conf. | |
340 | Implemented by Ulrich Drepper. | |
341 | \f | |

367 | ||
368 | * New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2 | |
369 | ||
370 | * Implement "e" option for popen to open file descriptor with the | |
371 | close-on-exec flag set. Implemented by Ulrich Drepper. | |
372 | ||
373 | * Implement "b" mode for fmemopen. In this mode writes writes don't | |
374 | implicitly add a NUL byte and seeks from the end of the buffer really | |
375 | use the buffer end, not the string length as the basis. | |
376 | Implemented by Ulrich Drepper. | |
377 | ||
378 | * Many functions, exported and internal, now atomically set the close-on-exec | |
379 | flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper. | |

404 | Implemented by Pravin Satpute. | |
405 | ||
406 | * IPV6 addresses in /etc/resolv.conf can now have a scope ID | |
407 | ||
408 | * nscd caches now all timeouts for DNS entries | |
409 | Implemented by Ulrich Drepper. | |
410 | ||
411 | * nscd is more efficient and wakes up less often. | |
412 | Implemented by Ulrich Drepper. | |

425 | Implemented by Ulrich Drepper. | |
426 | ||
427 | * Faster sqrt and sqrtf implemention for some PPC variants. | |
428 | Implemented by Stephen Munroe. | |

444 | ||
445 | * Implement 'm' modifier for scanf. Add stricter C99/SUS compliance | |
446 | by not recognizing 'a' as a modifier when those specs are requested. | |
447 | Implemented by Jakub Jelinek. | |
448 | ||
449 | * PPC optimizations to math and string functions. | |
450 | Implemented by Steven Munroe. | |

509 | 3225, 3251, 3252, 3253, 3273 | |
510 | ||
511 | * For Linux, the sorting of addresses returned by getaddrinfo now also | |
512 | handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled. | |
513 | Implemented by Ulrich Drepper. | |
514 | ||

516 | Implemented by Ulrich Drepper. | |
517 | ||
518 | * New Linux interfaces: splice, tee, sync_file_range, vmsplice. | |
519 | ||
520 | * New iconv module for MIK. Contributed by Alexander Shopov. | |
521 | ||
522 | * For sites with broken group and/or passwd database, the auto-propagate | |
523 | option of nscd can prevent creating ID lookup entries from the results | |
524 | of a name lookup and vice versa. This usually is no problem but some | |
525 | site might have problems with the default behavior. | |
526 | Implemented by Ulrich Drepper. | |
527 | ||
528 | * Iterating over entire database in NIS can be slow. With the | |
529 | SETENT_BATCH_READ option in /etc/default/nss a system admin can decide | |
530 | to trade time for memory. The entire database will be read at once. | |
531 | Implemented by Ulrich Drepper. | |
532 | ||
533 | * The interfaces introduced in RFC 3542 have been implemented by | |
534 | Ulrich Drepper. | |
535 | ||
536 | * Support for the new ELF hash table format was added by Ulrich Drepper. | |
537 | ||

546 | Version 2.4 | |
547 | ||
548 | * More overflow detection functions. | |
549 | ||
550 | * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153, | |
551 | IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba. | |
552 | ||
553 | More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097, | |

557 | IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed | |
558 | by Masahide Washizawa. | |
559 | ||
560 | * It is now possible to install audit libraries for the dynamic linker using | |
561 | LD_AUDIT. Implemented by Ulrich Drepper. | |
562 | ||
563 | * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no | |
564 | longer supported. The new NPTL implementation requires Linux 2.6 kernels. | |
565 | For a libc and libpthread that works well on Linux 2.4 kernels, we | |
566 | recommend using the stable 2.3 branch. | |
567 | ||
568 | * The new function open_wmemstream acts like open_memstream, | |
569 | but uses a wchar_t wide character buffer. | |
570 | ||
571 | * The new function ppoll is an improved version of poll, similar to pselect. | |
572 | ||
573 | * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat, | |
574 | futimesat, faccessat, mkdirat, mkfifoat, mknodat, | |
575 | renameat, unlinkat, linkat, symlinkat, readlinkat. | |
576 | ||
577 | * New Linux kernel system calls: unshare, | |
578 | inotify_init, inotify_add_watch, inotify_rm_watch. | |
579 | ||
580 | * The euidaccess function is now also known by the alias eaccess, | |
581 | for compatibility with some other systems. | |
582 | ||
583 | * Timezone data updated to 2006b version. | |

612 | \f | |
613 | Version 2.3.4 | |
614 | ||
615 | * Support for RFC 3678. Real implementations exist only for Linux so far. | |
616 | Implemented by Ulrich Drepper. | |
617 | ||
618 | * nscd can now cache entries persistently. Expiring entries are reloaded. | |
619 | For speedups the cache can be shared in memory with client processes. | |
620 | Implemented by Ulrich Drepper. | |
621 | ||
622 | * nscd can now perform SELinux checks. | |
623 | Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>. | |
624 | ||
625 | * getaddrinfo queries are now cached. Canonical name lookup is performed | |
626 | efficiently. | |
627 | Implemented by Ulrich Drepper. | |
628 | ||
629 | * The nothrow function attribute is used when headers are used by gcc when | |
630 | compiling C code. This can avoid significant amounts of exception | |
631 | handling data. | |
632 | ||
633 | * The malloc functions perform more error checking and are stricter when | |
634 | it comes to reacting on errors. The default action is to terminate | |
635 | the process after showing an error message. Implemented by Ulrich Drepper. | |
636 | ||
637 | * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int | |
638 | lookups anymore unless explicitly requested. Implemented by Ulrich Drepper. | |
639 | ||
640 | * Namespaces in ld.so are implemented. DSOs can be loaded in separate | |
641 | namespaces using the new function dlmopen(). This feature is of course, | |
642 | like most other dynamic loading functionality, not available in statically | |
643 | linked applications. Implemented by Ulrich Drepper. | |
644 | ||
645 | * Low-overhead boundary checking variants of string and some stdio functions | |
646 | were added. These are to be used in conjunction with a gcc patch by | |
647 | Jakub Jelinek which adds calls to these functions if possible. | |
648 | Implemented by Jakub Jelinek and Ulrich Drepper. | |
649 | ||
650 | * Old code for several operating systems and machine architectures that | |
651 | have not been in working condition in a long time have been removed from | |
652 | the main source tree maintained by the GNU C Library's maintainers. | |
653 | These files are now reside in the separate `ports' source module | |
654 | that is usable as an add-on when building the library. | |
655 | \f | |
656 | Version 2.3.3 | |
657 | ||
658 | * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to | |
659 | interrogate the dynamic linker, compatible with the Solaris interface. | |
660 | ||
661 | * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64; | |
662 | implemented by Paul Mackerras, Steven Munroe, and Roland McGrath. | |
663 | ||
664 | * getifaddrs now uses the netlink interface on Linux to get its information. | |
665 | Implemented by Thorsten Kukuk. | |
666 | ||
667 | * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF. | |
668 | Implemented by Ulrich Drepper. | |
669 | ||
670 | * support for non-executable stacks on x86 has been added. Changes mostly | |
671 | by Roland McGrath. | |
672 | ||
673 | * regex is now much faster for multibyte locales. Changes by Jakub Jelinek | |
674 | and Ulrich Drepper. | |
675 | ||
676 | * getaddrinfo now performs destination address selection according to | |
677 | RFC 3484. | |
678 | \f | |
679 | Version 2.3.2 | |
680 | ||
681 | * Thread-safe interfaces for many functions that access locale data | |
682 | were added in version 2.3, but these features were omitted from NEWS. | |
683 | Many functions have variants with an `_l' suffix that take a `locale_t' | |
684 | object as a parameter rather than consulting the current locale. | |
685 | The new functions `newlocale', `duplocale', and `freelocale' in <locale.h> | |
686 | create and maintain `locale_t' objects. Additionally, the new function | |
687 | `uselocale' sets "the current locale" (as used by functions not so | |
688 | parameterized) set for an individual thread. These features were added | |
689 | in version 2.3, implemented by Ulrich Drepper and Roland McGrath. | |
690 | ||
691 | * The functions getresuid, getresgid, setresuid, and setresgid, which | |
692 | have long been available on Linux, are now declared in <unistd.h> | |
693 | and are now also available on the Hurd. | |
694 | ||
695 | * ELF thread-local storage support (TLS) now works on x86-64. | |
696 | ||
697 | * The new dynamic string token $LIB is expanded in shared library names. | |
698 | This normally expands to lib, but on some 64-bit platforms to lib64 instead. | |
699 | ||
700 | * Aldy Hernandez contributed complete software floating point support for | |
701 | PowerPC machines with no FPU. | |
702 | ||
703 | * fexecve is implemented on Linux. | |
704 | ||
705 | * The `btowc' function should work at least twice as fast due to | |
706 | specialized callbacks in the iconv modules. Implemented by Bruno Haible. | |
707 | ||
708 | * With approriate thread add-ons cancelable functions are now implemented | |
709 | in libc.so as well. No need to call the function in libpthread. This | |
710 | change allowed to finally disable the incorrect and expensive handling | |
711 | of weak definition in ld.so. | |
712 | ||
713 | * Yet more PLT entries in libc.so have been removed. We finally arrived | |
714 | at the bare minimum. Startup times improved appropriately. | |
715 | ||
716 | * Support for the new Linux/x86 system call interface was added. The | |
717 | AT_SYSINFO auxiliary vector entry is recognized and handled. | |
718 | \f | |
719 | Version 2.3 | |
720 | ||
721 | * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164 | |
722 | charsets. | |
723 | ||
724 | * iconv (the program and the interface) now accepts empty names (excluding | |
725 | options like //TRANSLIT) to mean "use charset of current locale". | |
726 | ||
727 | * localedef can now transliterate characters in strings which are not in | |
728 | the provided charmap. The information from the input locale is used. | |
729 | ||
730 | * Prelinking support was added for ELF targets. This requires additional | |
731 | tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek. | |
732 | ||
733 | * Read-only stdio streams now use mmap to speed up operation by eliminating | |
734 | copying and buffer underflows. To use add 'm' to the mode string of | |
735 | the fopen/fdopen/freopen call. Implemented by Ulrich Drepper. | |
736 | ||
737 | * The malloc functions were completely rewritten by Wolfram Gloger based | |
738 | on Doug Lea's malloc-2.7.0.c. | |
739 | ||
740 | * Isamu Hasegawa contributed a completely new and POSIX-conformant | |
741 | implementation of regex. | |
742 | ||
743 | * Bruno Haible upgraded the iconv and locale implementation to support | |
744 | Unicode 3.2. | |
745 | ||
746 | * Contents of the LC_* and LANG environment variables in the CEN style are | |
747 | not recognized anymore. It never was used. Change by Ulrich Drepper. | |
748 | ||
749 | * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF | |
750 | thread-local storage (TLS) ABI on some platforms. | |
751 | Changes by Ulrich Drepper. SH support by Kaz Kojima. | |
752 | ||
753 | * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213, | |
754 | EUC-JISX0213, and TSCII. | |
755 | ||
756 | * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs': | |
757 | BSD-compatible interface for getting all network interface addresses. | |
758 | Implementation for IPv4 by Roland McGrath. | |
759 | ||
760 | * Loading of locale data is faster due to the introduction of a locale | |
761 | archive. Implemented by Roland McGrath and Ulrich Drepper. | |
762 | ||
763 | * Startup times are significantly reduced by not using exported functions | |
764 | inside the library itself. Changes by Jakub Jelinek, Roland McGrath, | |
765 | and Ulrich Drepper. | |
766 | ||
767 | * Steven Munroe contributed a port to PowerPC64/Linux. | |
768 | \f | |
769 | Version 2.2.6 | |
770 | ||
771 | * The Hurd now uses the GNU libio implementation of stdio rather than the | |
772 | old GNU stdio implementation, and uses a new ABI (libc.so.0.3). | |
773 | ||
774 | * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file | |
775 | with the same behavior as the Linux system call of the same name. | |
776 | \f | |
777 | Version 2.2.5 | |
778 | ||
779 | * Stephen Moshier implemented log2, log10, powl and cbrtl for the | |
780 | 128-bit long double format. | |
781 | ||
782 | * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160, | |
783 | IBM1161, and IBM1162 charsets. | |
784 | ||
785 | * Andreas Jaeger contributed a port to x86-64/Linux. | |
786 | ||
787 | * Peter Bruin contributed a port to PowerPC/Hurd. | |
788 | ||
789 | * libc functions using I/O streams now can handle wide-oriented streams | |
790 | as well. | |
791 | ||
792 | * optimizations in the dynamic linker. Binaries created by recent binutils | |
793 | versions start up quicker due to reduced time spent on relocations. | |
794 | ||
795 | * Support for use of gcc3 added by Jakub Jelinek and HJ Lu. | |
796 | \f | |
797 | Version 2.2.4 | |
798 | ||
799 | * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, | |
800 | asinh, atanh, j0 for the 128-bit long double format. | |
801 | ||
802 | * Bruno Haible updated all the code handling Unicode in some form to | |
803 | support Unicode 3.1. | |
804 | ||
805 | * Speed of regex for single-byte locales is back to previous levels. | |
806 | Patch by Isamu Hasegawa. | |
807 | ||
808 | * Alpha, SPARC, and IA-64 now also using floating stacks. | |
809 | ||
810 | * Startup time of internationalized applications greatly improved through | |
811 | iconv cache. Use iconvconfig to generate the cache file. | |
812 | Contributed by Ulrich Drepper. | |
813 | ||
814 | * The IA-64 specific part of ld.so was rewritten to eliminate some pretty | |
815 | severe performance problems. Patch by David Mosberger. | |
816 | ||
817 | * The Hurd port got a lot more functionality like AIO, various stdio | |
818 | extensions, etc. Mainly done by Roland McGrath. | |
819 | ||
820 | * mtrace can now lookup symbols in shared libraries. | |
821 | \f | |
822 | Version 2.2.3 | |
823 | ||
824 | * Intel's IA-64 math library is largely integrated. It provides fast and | |
825 | accurate implementatations for most basic and standard math functions | |
826 | in float, double, and long double format. | |
827 | ||
828 | * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, | |
829 | and asin for the 96-bit long double format and asin, log, tan for the | |
830 | 128-bit long double format. | |
831 | ||
832 | * The beginning of a last-bit accurate math library by IBM Haifa were added. | |
833 | The basic double functions exist today. Contributed by Abraham Ziv | |
834 | <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis | |
835 | <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. | |
836 | ||
837 | * An asynchronous name lookup library was added. The interface is designed | |
838 | after POSIX AIO. The proposal was circulated beforehand to get comments. | |
839 | No negative ones came in. Implemented by Ulrich Drepper. | |
840 | ||
841 | * Port to S390/64bit contributed by Martin Schwidefsky | |
842 | <schwidefsky@de.ibm.com>. | |
843 | ||
844 | * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family | |
845 | of functions for Linux/IA-64. | |
846 | ||
847 | * The RPC code is now thread safe. Threads can now use the same service | |
848 | of different services at the same time. Patch by Eric Norum | |
849 | <eric.norum@usask.ca> with some help by Ulrich Drepper. | |
850 | ||
851 | * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext | |
852 | family of functions for Linux/S390. | |
853 | ||
854 | * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family | |
855 | of functions for Linux/x86. | |
856 | ||
857 | * Port to Linux/CRIS contributed by Axis Communications. | |
858 | \f | |
859 | Version 2.2.2 | |
860 | ||
861 | * Lots of headers were cleaned up. Using the tool in the conform/ subdir | |
862 | we can now check for namespace violations and missing declarations. The | |
863 | result is that almost all headers are now Unix-compliant (as defined in | |
864 | the upcoming XPG6). The negative side is that some programs might need | |
865 | corrections, too, if they depend on the incorrect form of the headers in | |
866 | previous versions which defined too many symbols and included too many | |
867 | other headers. | |
868 | ||
869 | * regex now handles multibyte character sets correctly. | |
870 | Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. | |
871 | ||
872 | * iconv (the program) does now conform to the upcoming XPG6 and handles | |
873 | charmaps. Instead of the charset names the path of charmaps can be | |
874 | provided and the conversion happens based on this data. | |
875 | Contributed by Ulrich Drepper. | |
876 | ||
877 | * The locale program now provides detailed information about the installed | |
878 | locales. While | |
879 | ||
880 | locale -a | |
881 | ||
882 | only lists the names of the supported locales | |
883 | ||
884 | locale -a --verbose | |
885 | ||
886 | provides details such as country, language, and codeset name. | |
887 | Contributed by Ulrich Drepper. | |
888 | \f | |
889 | Version 2.2.1 | |
890 | ||
891 | * The gencat program now parses the input file according to the charset | |
892 | selected by the LC_CTYPE category. This is important for stateful | |
893 | character sets. To make generating catalogs easier there is a way | |
894 | to overwrite the charset selected by the locale: before the first | |
895 | message or $ quote line the catalog can contain a line like | |
896 | ||
897 | $ codeset=ISO-8859-2 | |
898 | ||
899 | to select the charset (ISO-8859-2 in this case). | |
900 | ||
901 | Implemented by Shinya Hanataka and Ulrich Drepper. | |
902 | ||
903 | * New codeset conversion modules: IBM-922 (Estonia PC codeset), | |
904 | IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). | |
905 | Contributed by Masahide Washizawa <washi@jp.ibm.com>. | |
906 | ||
907 | * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson | |
908 | <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. | |
909 | ||
910 | * The LANGUAGE environment variable is now ignored unless the locale is | |
911 | changed from the default "C" locale. | |
912 | ||
913 | * The usual bug fixes. | |
914 | \f | |
915 | Version 2.2 | |
916 | ||
917 | * Greg McGary added runtime support for bounds checking using gcc's | |
918 | new -fbounded-pointers option. ix86 target is complete. PowerPC | |
919 | is in progress. | |
920 | ||
921 | * Thorsten Kukuk added secure mode support to nscd. | |
922 | ||
923 | * The Berkeley db libraries have been removed. | |
924 | ||
925 | Related, the nss_db module is now in a separate package since it | |
926 | obviously requires a database library being available. | |
927 | ||
928 | * Wide character I/O streams implemented by Ulrich Drepper. | |
929 | ||
930 | * Functions from the extended socket API added by Ulrich Drepper. | |
931 | ||
932 | * Functions feenableexcept and fedisableexcept to control the | |
933 | behaviour of individual exceptions have been added by Andreas Jaeger. | |
934 | ||
935 | * ldconfig program added by Andreas Jaeger and Jakub Jelinek. | |
936 | ||
937 | * The resolver code has been updated from bind 8.2.3-T5B which supports | |
938 | threads. The integration was done by Andreas Jaeger, Adam D. Bradley, | |
939 | and Mark Kettenis. | |
940 | ||
941 | This change could in some situations effect backward compatibility. Since | |
942 | now `_res' is a thread-local instead of a global variable, modifying it | |
943 | in one thread does not have any effect in other threads. | |
944 | ||
945 | The resolver library was also extended to allow IPv6 as the transport | |
946 | protocol for the requests. This work was done by Stig Venaas. | |
947 | ||
948 | * Compatibility code for K&R C compilers has been removed from the | |
949 | header files. A ISO C compiler is needed to use the library | |
950 | (conforming to either C89 or C99 standard). | |
951 | ||
952 | * Complete rewrite of the localedef program to support multibyte character | |
953 | sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, | |
954 | strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. | |
955 | Implemented by Ulrich Drepper. | |
956 | ||
957 | Bruno Haible significantly improved the generation and use of the data | |
958 | structures for the wide character tables. | |
959 | ||
960 | * Plural handling in gettext implemented by Ulrich Drepper. | |
961 | ||
962 | * The utmp daemon has been removed. | |
963 | ||
964 | * The port to MIPS-Linux has been finished by Andreas Jaeger. | |
965 | ||
966 | * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima | |
967 | and Yutaka Niibe. | |
968 | ||
969 | * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. | |
970 | ||
971 | * POSIX barriers implemented by Kaz Kylheku. | |
972 | ||
973 | * POSIX spawn function family implemented by Ulrich Drepper. | |
974 | ||
975 | * POSIX spinlocks are now available. | |
976 | ||
977 | * Timed wait functions for mutex, rwlock, and semaphores are implemented. | |
978 | ||
979 | * the configure option --enable-kernel=X.Y.Z allows to strip out | |
980 | compatibility for kernel versions before X.Y.Z. This is currently only | |
981 | implemented for Linux. | |
982 | ||
983 | * the sockaddr_in6 structure changed. The IPv6 working group added a new | |
984 | field sin6_scope_id. This means that all programs using IPv6 should be | |
985 | recompiled. Don't expect binary compatibility with previous glibc | |
986 | versions. | |
987 | ||
988 | * various conversion modules for IBM character sets contributed by | |
989 | Masahide Washizawa. | |
990 | ||
991 | * IA-64 port by Jes Sorensen and HJ Lu. | |

994 | Compiling the GNU C Library for Linux/ia64 | |
995 | ****************************************** | |
996 | ||
997 | Please refer to the file INSTALL in the same directory as you found | |
998 | this file for general information about configuring and compiling | |
999 | glibc. | |
1000 | ||
1001 | For general inquiries about glibc under Linux/ia64 please use the | |
1002 | following mailing list linux-ia64@linuxia64.org or one of the relevant | |
1003 | glibc mailing lists. | |
1004 | ||
1005 | Recommended Tools for Compilation | |
1006 | ================================= | |
1007 | ||
1008 | In order for glibc-2.2 to build correctly on the ia64 you need at | |
1009 | least the following versions of the GNU tools (the : | |
1010 | ||
1011 | * The Cygnus toolchain snapshot for the ia64 as of August 4 | |
1012 | including the provided set of patches. It is however recommend | |
1013 | you use the October 24 toolchain snapshot or a more recent version. | |
1014 | ||
1015 | OR alternatively you can try the following (the Cygnus toolchain is | |
1016 | the recommended solution): | |
1017 | ||
1018 | * GCC and binutils, GAS and GNU LD out of CVS from | |
1019 | sources.redhat.com as of August 28, 2000 or later. The CVS tree | |
1020 | may require special patches to work properly on the ia64. | |
1021 | ||
1022 | Configuring and compiling GNU Libc for Linux/ia64 | |
1023 | ================================================= | |
1024 | ||
1025 | The library requires Linux kernel version 2.4.0-test4-000728 or | |
1026 | later to funtion properly. Besides that it support for debug libraries | |
1027 | is currently untested. Hence the following options | |
1028 | are required for configuring the library: | |
1029 | ||
1030 | --disable-debug --enable-kernel=2.4.0 | |
1031 | ||
1032 | It is also important that you make sure the library picks up the | |
1033 | appropriate kernel header files, if you do not have recent enough | |
1034 | kernel headers in /usr/src/linux/include, you should use the | |
1035 | --with-headers=<path> option to specify the location. | |
1036 | ||
1037 | As an example I personally use the following options to configure | |
1038 | the library: | |
1039 | ||
1040 | --disable-debug | |
1041 | --disable-cvs | |
1042 | --enable-kernel=2.4.0 | |
1043 | --host=ia64-linux | |
1044 | --enable-add-ons=yes | |
1045 | --prefix=/usr | |
1046 | --with-headers=/home/jes/linux/include | |
1047 | ||
1048 | ||
1049 | Good luck | |

1054 | \f | |
1055 | Version 2.1.3 | |
1056 | ||
1057 | * bug fixes | |
1058 | ||
1059 | \f | |
1060 | Version 2.1.2 | |
1061 | ||
1062 | * bug fixes | |
1063 | ||
1064 | \f | |
1065 | Version 2.1.1 | |
1066 | ||
1067 | * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added. | |
1068 | ||
1069 | * New xdr functions are added; some rpc functions are now 64bit clean. | |
1070 | ||
1071 | * Fixed a number of bugs and memory leaks (especially in NIS+ code). | |
1072 | ||
1073 | * Fixed known incompatibilities with glibc 2.0. | |
1074 | ||
1075 | * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. | |
1076 | ||
1077 | * Optimized a number of functions (especially the ELF dynamic loader). | |
1078 | ||
1079 | * Update timezone data files. | |
1080 | ||
1081 | * lots of charmaps corrections | |
1082 | ||
1083 | * some new locale definitions and charmaps | |
1084 | ||
1085 | \f | |
1086 | Version 2.1 | |
1087 | ||
1088 | * Richard Henderson corrected size of struct timeval on Linux/Alpha to | |
1089 | conform to POSIX member type requirements. Symbol versions have been | |
1090 | adjusted as needed within the library, and for direct use by applications, | |
1091 | but there is potential for problems if third-party libraries use | |
1092 | struct timeval as part of their interface. This does not present | |
1093 | a problem for X and other "essential" system libraries. | |
1094 | ||
1095 | * An additional locale model to support C++ Standard Library locale | |
1096 | model and probably more was implemented by Ulrich Drepper. | |
1097 | ||
1098 | * Eric Youngdale and Ulrich Drepper implemented versioning of objects on | |
1099 | symbol level. | |
1100 | ||
1101 | * Miles Bader provided the `argp' function family to support hierachical | |
1102 | command line argument parsing, layered on top of getopt. | |
1103 | ||
1104 | * strtod accepts new hexadecimal floating-point format from ISO C 9X. | |
1105 | ||
1106 | * printf has two new specifiers %a and %A to print hexadecimal flaoting-point | |
1107 | numbers. | |
1108 | ||
1109 | * scanf recognizes the %a and %A format for scanning floating point numbers. | |
1110 | ||
1111 | * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides | |
1112 | information and interfaces for the available integer types. | |
1113 | ||
1114 | * about 130 new math functions were added to implement the ISO C9x math | |
1115 | library. | |
1116 | ||
1117 | * the new header <complex.h> contains definitions of the complex math | |
1118 | functions from ISO C 9X. | |
1119 | ||
1120 | * the new header <tgmath.h> defines generic macros to use complex or | |
1121 | real valued functions. | |
1122 | ||
1123 | * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2. | |
1124 | ||
1125 | * Andreas Jaeger provided a test suite for the math library. | |
1126 | ||
1127 | * Mark Kettenis implemented the utmpx interface and an utmp daemon. | |
1128 | ||
1129 | * Ulrich Drepper added character set conversion functions (iconv). | |
1130 | ||
1131 | * Optimized string functions have been added. | |
1132 | ||
1133 | * The localedata addon is now part of glibc. | |
1134 | ||
1135 | * An implementation of profiling shared libraries was added by Ulrich Drepper. | |
1136 | ||
1137 | * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching | |
1138 | daemon for NSS (nscd). | |
1139 | ||
1140 | Missing a better place here are some numbers on improvements. Under | |
1141 | Linux 2.1.125 un-tar-ing the kernel sources takes | |
1142 | ||
1143 | user system wall | |
1144 | ||
1145 | using local files 12.19s 6.88s 22.91s | |
1146 | ||
1147 | using NIS 13.92s 8.91s 26.34s | |
1148 | ||
1149 | using NIS & nscd 10.37s 7.34s 25.30s | |
1150 | ||
1151 | using NIS+ 27.57s 30.37s 640.46s | |
1152 | ||
1153 | using NIS+ & nscd 10.25s 7.83s 26.51s | |
1154 | ||
1155 | using NIS & old nscd [1] 13.83s 8.32s 29.60s | |
1156 | ||
1157 | Keep in mind that non-namelookup related operations dominate above times. | |
1158 | It was just a common complain that using NIS+ unpacking the kernel is | |
1159 | horribly slow. | |
1160 | ||
1161 | [1] The old nscd implementation is not available anymore since it was | |
1162 | distributed with glibc up to version 2.0.98 and thus is now replaced. | |
1163 | ||
1164 | * Tim Waugh provided an implementation of the POSIX.2 wordexp function family. | |
1165 | ||
1166 | * Mark Kettenis provided a Hesiod NSS module. | |
1167 | ||
1168 | * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN | |
1169 | and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper). | |
1170 | ||
1171 | * rcmd can now handle netgroups (Dick Streefland). | |
1172 | ||
1173 | * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott | |
1174 | Bambrough. | |
1175 | ||
1176 | * Support for the IPv6 protocol has been added to the socket API, as per the | |
1177 | latest draft standards. | |
1178 | ||
1179 | * Support for Linux 2.2 has been added. | |
1180 | ||
1181 | * Interface changes relative to the latest 2.0.x release: | |

1550 | Version 2.0.1 | |
1551 | ||
1552 | * fixed lots of header problems (especially Linux/GNU specific) | |
1553 | ||
1554 | * dynamic loader preserves all registers | |
1555 | ||
1556 | * Roland McGrath provided support for handling of auxiliary objects in | |
1557 | the ELF dynamic loader. | |
1558 | ||
1559 | * support for parallel builds is improved | |
1560 | \f | |
1561 | Version 2.0 | |
1562 | ||
1563 | * GNU extensions are no longer declared by default. To enable them you | |
1564 | must define the macro `_GNU_SOURCE' in your program or compile with | |
1565 | `-D_GNU_SOURCE'. | |
1566 | ||
1567 | * The library has changed from using GNU ld symbol aliases to using weak | |
1568 | symbols where available. The ELF object file format supports weak | |
1569 | symbols; GNU ld also supports weak symbols in the a.out format. (There | |
1570 | is also now support for other GNU ld extensions in ELF. Use the | |
1571 | `--with-elf' option to configure to indicate you have ELF, and | |
1572 | `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion | |
1573 | of many files which contained only symbol aliases, reducing the size of | |
1574 | the source and the compiled library; many other files were renamed to | |
1575 | less cryptic names previously occupied by the symbol alias files. | |
1576 | There is a new header file <elf.h> for programs which operate on | |
1577 | files in the ELF format. | |
1578 | ||
1579 | * Converted to Autoconf version 2, so `configure' has more options. | |
1580 | Run `configure --help' to see the details. | |
1581 | ||
1582 | * The library can now be configured to build profiling, highly-optimized | |
1583 | (but undebuggable), and/or shared libraries (ELF with GNU ld only). The | |
1584 | `--enable-profile', `--enable-omitfp', and `--enable-shared' options to | |
1585 | `configure' enable building these extra libraries. The shared library is | |
1586 | built by default when using both ELF and GNU ld. When shared libraries | |
1587 | are enabled, the new library `-ldl' is available for arbitrary run-time | |
1588 | loading of shared objects; its interface is defined in <dlfcn.h>. The | |
1589 | new header file <link.h> gives access to the internals of the run-time | |
1590 | dynamic linker, `ld.so'. The shell script `ldd' is similar to the | |
1591 | application of same name on other systems and it provides information | |
1592 | about dynamically linked binaries. | |
1593 | ||
1594 | * The C library now provides the run-time support code for profiling | |
1595 | executables compiled with `-pg'. Programs can control the profiling code | |
1596 | through the interface in <sys/gmon.h>. The `gmon.out' files written by | |
1597 | the GNU C library can be read only by GNU `gprof' (from GNU binutils); | |
1598 | the support for this file format was contributed by David Mosberger-Tang. | |
1599 | ||
1600 | * The math code has been replaced with a math library based on fdlibm from | |
1601 | Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by | |
1602 | Ian Taylor with `float' functions and by Ulrich Drepper with `long double' | |
1603 | functions. The math functions now reside in a separate library, so | |
1604 | programs using them will need to use `-lm' their linking commands. | |
1605 | ||
1606 | * John C. Bowman contributed optimized ix87 assembler inline functions. | |
1607 | ||
1608 | * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' | |
1609 | mechanism similar to that found in Solaris 2. This is now used for the | |
1610 | group, passwd, hosts, networks, services, protocols, rpc, ethers, | |
1611 | shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' | |
1612 | file controls what services are used for each individual database. This | |
1613 | works by loading shared libraries with names specified in `nsswitch.conf', | |
1614 | so service modules can be changed or added at any time without even | |
1615 | relinking any program. Currently there are the file, db, and NIS based | |
1616 | NSS services available. | |
1617 | ||
1618 | * The new functions `strtoq' and `strtouq' parse integer values from | |
1619 | strings, like `strtol' and `strtoul', but they return `long long int' and | |
1620 | `unsigned long long int' values, respectively (64-bit quantities). | |
1621 | ||
1622 | * The new functions `strtof' and `strtold' parse floating-point values from | |
1623 | strings, like `strtod', but they return `float' and `long double' values, | |
1624 | respectively (on some machines `double' and `long double' are the same). | |
1625 | ||
1626 | * Ulrich Drepper has contributed new implementations of the floating-point | |
1627 | printing and reading code used in the `printf' family of functions and | |
1628 | `strtod', `strtof', and `strtold'. These new functions are perfectly | |
1629 | accurate, and much faster than the old ones. | |
1630 | ||
1631 | * The implementation of the POSIX locale model was completely rewritten by | |
1632 | Ulrich Drepper. This includes the new programs `localedef' and `locale' | |
1633 | to compile the POSIX locale definition. | |
1634 | ||
1635 | * The former dummy implementations of the strcoll and strxfrm function are | |
1636 | now replaced by fully functional code contributed by Ulrich Drepper. The | |
1637 | collation information comes from the POSIX locale definitions. | |
1638 | ||
1639 | * The new header <langinfo.h> defines an interface for accessing | |
1640 | various locale-dependent data (using the locale chosen with `setlocale'). | |
1641 | ||
1642 | * Ulrich Drepper has contributed a new suite of functions for operation on | |
1643 | wide-character and multibyte-character strings, in <wchar.h>; | |
1644 | and classification and case conversion of wide characters, in <wctype.h>. | |
1645 | These new functions are conforming to the ISO C, Amendement 1 specification. | |
1646 | ||
1647 | * There is now a second implementation of the standard I/O library available. | |
1648 | It comes from GNU libg++ as was written by Per Bothner, heavily modified | |
1649 | by Hongjiu Lu and made thread safe by Ulrich Drepper. | |
1650 | ||
1651 | * You can now use positional parameter specifications in format strings | |
1652 | for the `printf' and `scanf' families of functions. For example, | |
1653 | `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints | |
1654 | ``Number 6, Mr Jones''. This is mainly useful when providing different | |
1655 | format strings for different languages, whose grammars may dictate | |
1656 | different orderings of the values being printed. To support this | |
1657 | feature, the interface for `register_printf_handler' has changed; see | |
1658 | the header file <printf.h> for details. | |
1659 | ||
1660 | * The `printf' and `scanf' families of functions now understand a new | |
1661 | formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says | |
1662 | to group numbers as indicated by the locale; for `scanf' and friends, this | |
1663 | says to accept as valid only a number with all the proper grouping | |
1664 | separators in the right places. In the default "C" locale, numbers are | |
1665 | not grouped; but locales for specific countries will define the usual | |
1666 | conventions (i.e. separate thousands with `,' in the US locale). | |
1667 | ||
1668 | * The pgrp functions have been regularized, slightly incompatibly but much | |
1669 | less confusingly. The core functions are now `getpgid' and `setpgid', | |
1670 | which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no | |
1671 | argument) and BSD `setpgrp' (identical to `setpgid') functions are | |
1672 | provided for compatibility. There is no longer an incompatible `getpgrp' | |
1673 | with an argument declared under _BSD_SOURCE; no BSD code uses it. | |
1674 | ||
1675 | * The new header file <fts.h> and suite of functions simplify programs that | |
1676 | operate on directory trees. This code comes from 4.4 BSD. | |
1677 | ||
1678 | * The resolver code has been updated from the BIND 4.9.5-P1 release. | |
1679 | Parts of the code were heavily modified by Ulrich Drepper to fit in the | |
1680 | NSS scheme used in glibc. | |
1681 | ||
1682 | * There is a new malloc debugging hook `__memalign_hook'. | |
1683 | ||
1684 | * There are new typedefs `ushort' for `unsigned short int' and `uint' for | |
1685 | `unsigned int' in <sys/types.h>. These are for compatibility only and | |
1686 | their use is discouraged. | |
1687 | ||
1688 | * The `-lmcheck' library to enable standard malloc debugging hooks is now | |
1689 | done differently, so that it works even without GNU ld. | |
1690 | ||
1691 | * New function `euidaccess' checks allowed access to a file like `access', | |
1692 | but using the effective IDs instead of the real IDs. | |
1693 | ||
1694 | * The time zone data files have been updated for the latest and greatest | |
1695 | local time conventions of the countries of the world. | |
1696 | ||
1697 | * The new function `dirfd' extracts the file descriptor used by a DIR stream; | |
1698 | see <dirent.h>. | |
1699 | ||
1700 | * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface | |
1701 | for formatting floating-point numbers. They are provided only for | |
1702 | compatibility; new programs should use `sprintf' instead. There are | |
1703 | also equivalent function for the `long double' floating-point type and | |
1704 | all functions also exist in a reentrant form. | |
1705 | ||
1706 | * The new auxiliary library `-lutil' from 4.4 BSD contains various | |
1707 | functions for maintaining the login-record files (primarily of use to | |
1708 | system programs such as `login'), and convenient functions for | |
1709 | allocating and initializing a pseudo-terminal (pty) device. | |
1710 | ||
1711 | * Ulrich Drepper has contributed new support for System V style | |
1712 | shared memory and IPC on systems that support it. | |
1713 | ||
1714 | * Ulrich Drepper has contributed several miscellaneous new functions found | |
1715 | in System V: The `hsearch' family of functions provide an effective | |
1716 | implementation of hash tables; `a64l' and `l64a' provide a very simple | |
1717 | binary to ASCII mapping; `drand48' and friends provide a 48-bit random | |
1718 | number generator. | |
1719 | ||
1720 | * Ulrich Drepper has contributed new reentrant counterparts for the | |
1721 | `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. | |
1722 | ||
1723 | * Ulrich Drepper has contributed new, highly-optimized versions of several | |
1724 | string functions for the i486/Pentium family of processors. | |
1725 | ||
1726 | * Ulrich Drepper has updated the Linux-specific code, based largely | |
1727 | on work done in Hongjiu Lu's version of GNU libc for Linux. | |
1728 | The GNU library now supports Linux versions 2.0.10 and later, | |
1729 | using the ELF object file format (i[3456]86-*-linux). | |
1730 | ||
1731 | * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). | |
1732 | ||
1733 | * David Mosberger-Tang and Richard Henderson have ported the C library | |
1734 | to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the | |
1735 | dynamic linking support for ELF/Alpha. | |
1736 | ||
1737 | * Richard Henderson contributed several Alpha optimized assembler function | |
1738 | for arithmetic and string handling. | |
1739 | ||
1740 | * Ulrich Drepper has contributed a new set of message catalog functions to | |
1741 | support multiple languages using the <libintl.h> interface, for use with | |
1742 | his new package GNU gettext. Translation volunteers have contributed | |
1743 | catalogs of the library's messages in Spanish, German, and Korean. | |
1744 | ||
1745 | * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' | |
1746 | program and the `catgets' function for reading the catalog files it | |
1747 | creates. (The <libintl.h> interface is preferred; we include the | |
1748 | <nl_types.h> interface using `catgets' only for source compatibility with | |
1749 | programs already written to use it.) | |
1750 | ||
1751 | * New header file <values.h> gives SVID-compatible names for <limits.h> | |
1752 | constants. | |
1753 | ||
1754 | * Various new macros, declarations, and small header files for compatibility | |
1755 | with 4.4 BSD. | |
1756 | ||
1757 | * New function `group_member' is a convenient way to check if a process has | |
1758 | a given effective group ID. | |
1759 | ||
1760 | * When using GCC 2.7 and later, the socket functions are now declared in a | |
1761 | special way so that passing an argument of type `struct sockaddr_in *', | |
1762 | `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic | |
1763 | `struct sockaddr *' type, does not generate a type-clash warning. | |
1764 | ||
1765 | * New function `error' declared in header file <error.h> is a convenient | |
1766 | function for printing error messages and optionally exiting; this is the | |
1767 | canonical function used in GNU programs. The new functions `err', `warn', | |
1768 | and friends in header file <err.h> are the canonical 4.4 BSD interface for | |
1769 | doing the same thing. | |
1770 | ||
1771 | * The <glob.h> interface has several new flags from 4.4 BSD that extend the | |
1772 | POSIX.2 `glob' function to do ~ and {...} expansion. | |
1773 | ||
1774 | * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. | |
1775 | `clearenv' which is used in POSIX.9 is also available. | |
1776 | ||
1777 | * New function `getsid' returns session ID number on systems that support it. | |
1778 | ||
1779 | * We have incorporated the 4.4 BSD `db' library (version 1.85). New header | |
1780 | files <db.h> and <mpool.h> provide a rich set of functions for several | |
1781 | types of simple databases stored in memory and in files, and <ndbm.h> is | |
1782 | an old `ndbm'-compatible interface using the `db' functions. Link with | |
1783 | `-ldb' to get these functions. | |
1784 | ||
1785 | * New macro `strdupa' copies a string like `strdup', but uses local stack | |
1786 | space from `alloca' instead of dynamic heap space from `malloc'. | |
1787 | ||
1788 | * New function `strnlen' is like `strlen' but searches only a given maximum | |
1789 | number of characters for the null terminator. `stpncpy', `strndup' and | |
1790 | `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' | |
1791 | function. | |
1792 | ||
1793 | * New function `statfs' in header <sys/statfs.h>. | |
1794 | ||
1795 | * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader | |
1796 | provide convenient functions for operating on blocks of null-terminated | |
1797 | strings. | |
1798 | ||
1799 | * A new suite of functions in <utmp.h> handle all the details of reading | |
1800 | and writing the utmp file. | |
1801 | ||
1802 | * An implementation of the NIS/YP(tm) based NSS service was contributed by | |
1803 | Thorsten Kukuk. | |
1804 | ||
1805 | * Paul Eggert and Ulrich Drepper modified the `strftime' function to be | |
1806 | completely POSIX compliant and also implemented the extended functionality | |
1807 | to handle alternate digit representation and alternate era date formats. | |
1808 | ||
1809 | * Ulrich Drepper provided an implementation of the `strptime' function | |
1810 | defined in XPG4.2 which transforms a string into a `struct tm' value. | |
1811 | ||
1812 | * Paul Eggert provided the tzselect shell script as part of the timezone | |
1813 | code. The shell script makes it easy to select the correct timezone | |
1814 | specification. | |
1815 | ||
1816 | * The implementation of the malloc family of functions is completely replaced | |
1817 | by a new implementation by Doug Lea with many improvements by Wolfram Gloger. | |
1818 | The implementation uses the mmap function (if available) and it is | |
1819 | optimized for the use in multi threaded programs. | |
1820 | ||
1821 | * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of | |
1822 | functions. This new functionality is usable by specifying a special | |
1823 | salt string and it is compatible with implementation on *BSD systems. | |
1824 | ||
1825 | * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: | |
1826 | `getsubopt' to handle second level command line options, `bsd_signal' | |
1827 | to access BSD style `signal' functionality, the obsolete `regexp' style | |
1828 | expression matcher. | |
1829 | ||
1830 | * the `lchown' function is available on system which support this | |
1831 | functionality. | |
1832 | ||
1833 | * The implementation of the shadow password handling function was contributed | |
1834 | by Ulrich Drepper. | |
1835 | ||
1836 | * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. | |
1837 | ||
1838 | * POSIX.1g support was added. The <sys/select.h> header is available, | |
1839 | `isfdtype' and `pselect' are implemented. Craig Metz contributed an | |
1840 | implementation of `getaddrinfo'. | |
1841 | \f | |
1842 | Version 1.09 | |
1843 | ||
1844 | * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. | |
1845 | ||
1846 | * New header file <fstab.h> and new functions `getfsspec', `getfsent' and | |
1847 | friends, for parsing /etc/fstab. This code comes from 4.4 BSD. | |
1848 | ||
1849 | * The new function `daemon' from 4.4 BSD is useful for server programs that | |
1850 | want to put themselves in the background. | |
1851 | ||
1852 | * Joel Sherrill has contributed support for several standalone boards that | |
1853 | run without an operating system. | |
1854 | ||
1855 | * `printf', `scanf' and friends now accept a `q' type modifier for long | |
1856 | long int as well as `ll'. Formats using these might be `%qu' or `%lld'. | |
1857 | ||
1858 | * All of the code taken from BSD (notably most of the math and networking | |
1859 | routines) has been updated from the BSD 4.4-Lite release. | |
1860 | ||
1861 | * The resolver code has been updated from the BIND-4.9.3-BETA9 release. | |
1862 | ||
1863 | * The new functions `getdomainname' and `setdomainname' fetch or change the | |
1864 | YP/NIS domain name. These are system calls which exist on systems which | |
1865 | have YP (aka NIS). | |
1866 | ||
1867 | * The time zone data files have been updated for the latest international | |
1868 | conventions. | |
1869 | ||
1870 | * The SunRPC programs `portmap' and `rpcinfo' are now installed in | |
1871 | $(sbindir) (usually /usr/local/sbin) instead of $(bindir). | |
1872 | \f | |
1873 | Version 1.08 | |
1874 | ||
1875 | * The C library now includes support for Sun RPC, from Sun's free | |
1876 | RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs | |
1877 | are included. (There is still no support for YP.) | |
1878 | ||
1879 | * Tom Quinn has contributed a port of the C library to SGI machines running | |
1880 | Irix 4 (mips-sgi-irix4). | |
1881 | ||
1882 | * The new `lockf' function is a simplified interface to the locking | |
1883 | facilities of `fcntl', included for compatibility. | |
1884 | ||
1885 | * New time functions `timegm', `timelocal', and `dysize' for compatibility. | |
1886 | ||
1887 | * New header file <sys/timeb.h> and new function `ftime' for compatibility. | |
1888 | ||
1889 | * New header files <poll.h> and <sys/poll.h> and new function `poll' for | |
1890 | compatibility. | |
1891 | ||
1892 | * The error message printed by `assert' for a failed assertion now includes | |
1893 | the name of the program (if using GNU ld) and the name of the calling | |
1894 | function (with versions of GCC that support this). | |
1895 | ||
1896 | * The `psignal' function is now declared in <signal.h>, not <stdio.h>. | |
1897 | ||
1898 | * The library now includes the <sys/mman.h> header file and memory | |
1899 | management functions `mmap', `munmap', `mprotect', `msync', and | |
1900 | `madvise', on systems that support those facilities. | |
1901 | ||
1902 | * The interface for `mcheck' has changed slightly: the function called to | |
1903 | abort the program when an allocation inconsistency is detected now takes | |
1904 | an argument that indicates the type of failure. The new function | |
1905 | `mprobe' lets you request a consistency check for a particular block at | |
1906 | any time (checks are normally done only when you call `free' or `realloc' | |
1907 | on a block). | |
1908 | ||
1909 | * It is now possible to easily cross-compile the C library, building on one | |
1910 | system a library to run on another machine and/or operating system. All | |
1911 | you need to do is set the variable `HOST_CC' in `configparms' to the | |
1912 | native compiler for programs to run on the machine you are building on (a | |
1913 | few generator programs are used on Unix systems); set `CC' to the | |
1914 | cross-compiler. | |
1915 | ||
1916 | * The new function `fexecve' (only implemented on the GNU system) executes | |
1917 | a program file given a file descriptor already open on the file. | |
1918 | \f | |
1919 | Version 1.07 | |
1920 | ||
1921 | * Brendan Kehoe has contributed most of a port to the DEC Alpha | |
1922 | running OSF/1 (alpha-dec-osf1). He says it is 75% complete. | |
1923 | ||
1924 | * You can set the variable `libprefix' in `configparms' to specify a prefix | |
1925 | to be prepended to installed library files; this makes it easy to install | |
1926 | the GNU C library to be linked as `-lgnuc' or whatever. | |
1927 | ||
1928 | * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It | |
1929 | copies a limited number of characters from a string, and returns the | |
1930 | address of the last character written. | |
1931 | ||
1932 | * You no longer need to check for whether the installed `stddef.h' is | |
1933 | compatible with the GNU C library. configure now checks for you. | |
1934 | ||
1935 | * You can now define a per-stream `fileno' function to convert the | |
1936 | stream's cookie into an integral file descriptor. | |
1937 | ||
1938 | * ``malloc (0)'' no longer returns a null pointer. Instead, it | |
1939 | allocates zero bytes of storage, and returns a unique pointer which | |
1940 | you can pass to `realloc' or `free'. The behavior is undefined if | |
1941 | you dereference this pointer. | |
1942 | ||
1943 | * The C library now runs on Sony NEWS m68k machines running either | |
1944 | NewsOS 3 or NewsOS 4. | |
1945 | ||
1946 | * The new `syscall' function is a system-dependent primitive function | |
1947 | for invoking system calls. It has the canonical behavior on Unix | |
1948 | systems, including unreliable return values for some calls (such as | |
1949 | `pipe', `fork' and `getppid'). | |
1950 | ||
1951 | * The error code `EWOULDBLOCK' is now obsolete; it is always defined | |
1952 | to `EAGAIN', which is the preferred name. On systems whose kernels | |
1953 | use two distinct codes, the C library now translates EWOULDBLOCK to | |
1954 | EAGAIN in every system call function. | |
1955 | \f | |
1956 | Version 1.06 | |
1957 | ||
1958 | * The GNU C Library Reference Manual is now distributed with the library. | |
1959 | `make dvi' will produce a DVI file of the printed manual. | |
1960 | `make info' will produce Info files that you can read on line using C-h i | |
1961 | in Emacs or the `info' program. | |
1962 | Please send comments on the manual to bug-glibc-manual@gnu.org. | |
1963 | ||
1964 | * The library now supports SVR4 on i386s (i386-unknown-sysv4). | |
1965 | ||
1966 | * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. | |
1967 | ||
1968 | * Jason Merrill has contributed a port to the Sequent Symmetry running | |
1969 | Dynix version 3 (i386-sequent-dynix). | |
1970 | ||
1971 | * The library has been ported to i386s running SCO 3.2.4 (also known as SCO | |
1972 | ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). | |
1973 | ||
1974 | * New function `memory_warnings' lets you arrange to get warnings when | |
1975 | malloc is running out of memory to allocate, like Emacs gives you. | |
1976 | ||
1977 | * The C library now contains the relocating allocator used in Emacs 19 for | |
1978 | its editing buffers. This allocator (ralloc) minimizes allocation | |
1979 | overhead and fragmentation by moving allocated regions around whenever it | |
1980 | needs to. You always refer to a ralloc'd region with a "handle" (a | |
1981 | pointer to a pointer--an object of type `void **'). | |
1982 | ||
1983 | * There is a new `printf' format: `%m' gives you the string corresponding | |
1984 | to the error code in `errno'. | |
1985 | ||
1986 | * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' | |
1987 | or `%[' conversion, but instead of filling in a fixed-sized buffer you | |
1988 | pass, the `a' modifier says to fill in a `char **' you pass with a | |
1989 | malloc'd string. | |
1990 | ||
1991 | * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and | |
1992 | `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a | |
1993 | name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. | |
1994 | ||
1995 | * `mkstemp' is a traditional Unix function to atomically create and open a | |
1996 | uniquely-named temporary file. | |
1997 | \f | |
1998 | Version 1.05 | |
1999 | ||
2000 | * The standard location for the file that says what the local timezone is | |
2001 | has changed again. It is now `/usr/local/etc/localtime' (or more | |
2002 | precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. | |
2003 | ||
2004 | * The distribution no longer contains any files with names longer than 14 | |
2005 | characters. | |
2006 | ||
2007 | * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. | |
2008 | These are set by the new `trusted' and `console' keywords in `/etc/ttys'. | |
2009 | ||
2010 | * New functions `ttyslot' and `syslog' from 4.4 BSD. | |
2011 | \f | |
2012 | Version 1.04 | |
2013 | ||
2014 | * The configuration process has changed quite a bit. The `configure' | |
2015 | script is now used just like the configuration scripts for other GNU | |
2016 | packages. The `sysdeps' directory hierarchy is much rearranged. | |
2017 | The file `INSTALL' explains the new scheme in detail. | |
2018 | ||
2019 | * The header files no longer need to be processed into ANSI C and | |
2020 | traditional C versions. There is just one set of files to install, and | |
2021 | it will work with ANSI or old C compilers (including `gcc -traditional'). | |
2022 | ||
2023 | * Brendan Kehoe and Ian Lance Taylor have ported the library to the | |
2024 | MIPS DECStation running Ultrix 4. | |
2025 | ||
2026 | * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. | |
2027 | Tom Quinn contributed the initial code. The GNU C library can NOT yet be | |
2028 | made itself into a shared library. | |
2029 | ||
2030 | * Yet further improved support for the i386, running 4.3 BSD-like systems | |
2031 | (such as Mach 3 with the Unix single-server), or System V. | |
2032 | ||
2033 | * New function `strncasecmp' to do case-insensitive string comparison | |
2034 | with limited length. | |
2035 | ||
2036 | * New function `strsep' is a reentrant alternative to `strtok'. | |
2037 | ||
2038 | * New functions `scandir' and `alphasort' for searching directories. | |
2039 | ||
2040 | * New function `setenv' is a better interface to `putenv'. | |
2041 | ||
2042 | * Ian Lance Taylor has contributed an implementation of the SVID `ftw' | |
2043 | function for traversing a directory tree. | |
2044 | ||
2045 | * The GNU obstack package is now also part of the C library. | |
2046 | The new function `open_obstack_stream' creates a stdio stream that | |
2047 | writes onto an obstack; `obstack_printf' and `obstack_vprintf' do | |
2048 | formatted output directly to an obstack. | |
2049 | ||
2050 | * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), | |
2051 | cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. | |
2052 | ||
2053 | * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. | |
2054 | ||
2055 | * The new functions `strfry' and `memfrob' do mysterious and wonderful | |
2056 | things to your strings. | |
2057 | ||
2058 | * There are some new test programs: test-fseek, testmb, and testrand. | |
2059 | ||
2060 | * Some work has been done to begin porting the library to 4.4 BSD and Linux. | |
2061 | These ports are not finished, but are a good starting place for really | |
2062 | supporting those systems. | |
2063 | ||
2064 | * `/etc/localtime' is now the standard location for the file that says what | |
2065 | the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. | |
2066 | This follows the general principle that `/etc' is the place for all local | |
2067 | configuration files. | |
2068 | ||
2069 | * The C library header files now use `extern "C"' when used by the C++ | |
2070 | compiler, so the C library should now work with C++ code. | |
2071 | ||
2072 | * The header file <bstring.h> is gone. <string.h> now declares bcopy, | |
2073 | bcmp, bzero, and ffs. (Update: nowadays these functions are declared | |
2074 | in <strings.h>.) | |
2075 | ||
2076 | * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting | |
2077 | function which uses the `merge sort' algorithm, and is said to be | |
2078 | significantly faster than the old GNU `qsort' function. Merge sort is | |
2079 | now the standard `qsort' function. The new algorithm can require a lot | |
2080 | of temporary storage; so, the old sorting function is called when the | |
2081 | required storage is not available. | |
2082 | ||
2083 | * The C library now includes Michael Glad's Ultra Fast Crypt, which | |
2084 | provides the Unix `crypt' function, plus some other entry points. | |
2085 | ||
2086 | * The code and header files taken from 4.4 BSD have been updated with the | |
2087 | latest files released from Berkeley. | |
