23 15490, 15492, 15493, 15497, 15506, 15529, 15536, 15553, 15577, 15583,
24 15618, 15627, 15631, 15654, 15655, 15666, 15667, 15674.
26 * CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
27 #15078).
29 * CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
30 fixed (Bugzilla #15330).
32 * Add support for calling C++11 thread_local object destructors on thread
33 and program exit. This needs compiler support for offloading C++11
34 destructor calls to glibc.
36 * Improved worst case performance of libm functions with double inputs and
37 output.
39 * Support for priority inherited mutexes in pthread condition variables on
40 non-x86 architectures.
42 * Port to Xilinx MicroBlaze contributed by David Holsgrove.
44 * Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
46 * Optimized string functions for ARM. Implemented by Will Newton and
47 Richard Henderson.
49 * Optimized libm functions for SPARC. Implemented by David S. Miller.
51 * Support for building more of ARM glibc as Thumb-2 code. Implemented by
52 Richard Henderson.
54 * Support for building most of MIPS glibc as MIPS16 code. Implemented by
55 Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
57 * Added a benchmark framework to track performance of functions in glibc.
59 * New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
60 It is based on draft TS 18661 and currently enabled as a GNU extension.
62 * On Linux, the clock function now uses the clock_gettime system call
63 for improved precision, rather than old times system call.
65 * Added new API functions pthread_getattr_default_np and
66 pthread_setattr_default_np to get and set the default pthread
67 attributes of a process.

69 Version 2.17
71 * The following bugs are resolved with this release:
73 1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808,
74 9685, 9914, 10014, 10038, 10114, 10191, 10631, 10873, 11438, 11607, 11638,
75 11741, 12140, 13013, 13412, 13542, 13601, 13603, 13604, 13629, 13679,
76 13696, 13698, 13717, 13741, 13759, 13761, 13763, 13881, 13939, 13950,
77 13952, 13966, 14042, 14047, 14090, 14150, 14151, 14152, 14154, 14157,
78 14166, 14173, 14195, 14197, 14237, 14246, 14251, 14252, 14283, 14298,
79 14303, 14307, 14328, 14331, 14336, 14337, 14347, 14349, 14368, 14376,
80 14417, 14447, 14459, 14476, 14477, 14501, 14505, 14510, 14516, 14518,
81 14519, 14530, 14532, 14538, 14543, 14544, 14545, 14557, 14562, 14568,
82 14576, 14579, 14583, 14587, 14595, 14602, 14610, 14621, 14638, 14645,
83 14648, 14652, 14660, 14661, 14669, 14672, 14683, 14694, 14716, 14719,
84 14743, 14767, 14783, 14784, 14785, 14793, 14796, 14797, 14801, 14803,
85 14805, 14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833,
86 14835, 14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872,
87 14879, 14889, 14893, 14898, 14914.
89 * Optimization of memcpy for MIPS.
91 * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
92 EMFILE has been fixed (Bugzilla #14889).
94 * The add-on ports collection is now distributed in the "ports" subdirectory
95 of the main GNU C Library distribution, rather than separately.
97 * Port to ARM AArch64 contributed by Linaro.
99 * Support for STT_GNU_IFUNC symbols added for s390 and s390x.
100 Optimized versions of memcpy, memset, and memcmp added for System z10 and
101 zEnterprise z196.
102 Implemented by Andreas Krebbel.
104 * The new function secure_getenv allows secure access to the environment,
105 returning NULL if running in a SUID/SGID process. This function replaces
106 the internal function __secure_getenv.
108 * SystemTap static probes have been added into the dynamic linker.
109 Implemented by Gary Benson.
111 * Optimizations of string functions strstr, strcasestr and memmem.
112 Implemented by Maxim Kuvyrkov.
114 * The minimum Linux kernel version that this version of the GNU C Library
115 can be used with is 2.6.16.
117 * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
118 powerpc POWER7. Implemented by Will Schmidt.
120 * New configure option --disable-nscd builds the C library such that it
121 never attempts to contact the Name Service Caching Daemon (nscd).
122 New configure option --disable-build-nscd avoids building nscd itself;
123 this is the default if --disable-nscd is used.
125 * Improved support for cross-compilation, including cross-testing and
126 bootstrap builds without a previously built glibc.
128 * Several testsuite tests are now able to test multiple IFUNC variants of an
129 interface, rather than just testing the one that would be chooen by
130 default.
132 * New configure options --with-bugurl and --with-pkgversion, for
133 distributors to use to embed their bug-reporting and package version
134 information in --help and --version output.
136 * The ttyname and ttyname_r functions on Linux now fall back to searching for
137 the tty file descriptor in /dev/pts or /dev if /proc is not available. This
138 allows creation of chroots without the procfs mounted on /proc.
140 * The `crypt' function now fails if passed salt bytes that violate the
141 specification for those values. On Linux, the `crypt' function will
142 consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
143 enabled, and fail on encrypted strings using the MD5 or DES algorithm
144 when the mode is enabled.
146 * The `clock_*' suite of functions (declared in <time.h>) is now available
147 directly in the main C library. Previously it was necessary to link with
148 -lrt to use these functions. This change has the effect that a
149 single-threaded program that uses a function such as `clock_gettime' (and
150 is not linked with -lrt) will no longer implicitly load the pthreads
151 library at runtime and so will not suffer the overheads associated with
152 multi-thread support in other code such as the C++ runtime library.
154 * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
155 sat_IN, and szl_PL.

183 14277, 14278.
185 * Support for the x32 ABI on x86-64 added. The x32 target is selected by
186 configuring glibc with:
187 BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
188 Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
189 Implemented by H.J. Lu.
191 * ISO C11 support:
193 + define static_assert
195 + do not declare gets
197 + declare at_quick_exit and quick_exit also for ISO C11
199 + aligned_alloc. NB: The code is deliberately allows the size parameter
200 to not be a multiple of the alignment. This is a moronic requirement
201 in the standard but it is only a requirement on the caller, not the
202 implementation.
204 + timespec_get added
206 + uchar.h support added
208 + CMPLX, CMPLXF, CMPLXL added
210 Implemented by Ulrich Drepper.
212 * Support for the IA-64 has been moved to ports.
214 * Remove support for anything but ELF binary format
216 * Checking versions of poll, ppoll added.
217 Implemented by Ulrich Drepper.
219 * More generic and 64-bit performance optimizations to math functions.
220 Implemented by Ulrich Drepper.
222 * New configure option --enable-obsolete-rpc makes the deprecated RPC
223 headers and functions available at compile time as they were before
224 version 2.14. This option will be removed at some time in the future
225 after the TI-RPC library becomes fully sufficient for the needs of
226 existing applications.
228 * Compatibility code for Linux kernel versions before 2.4 has been removed.
229 Note that glibc is not expected to work with any Linux kernel version
230 before 2.6.
232 * New header <sys/auxv.h> and function getauxval allowing easy access to
233 the AT_* key-value pairs passed from the Linux kernel. The header also
234 defines the HWCAP_* bits associated with the AT_HWCAP key.
236 * New locales: mag_IN
238 * New configure option --enable-systemtap builds SystemTap static probes
239 into libc for setjmp and longjmp and into libpthread for various operations.
240 So far the setjmp/longjmp probes and some of the libpthread probes are
241 provided only for i*86 and x86_64.
242 Implemented by Roland McGrath and Rayson Ho.
244 * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
246 * More optimized functions for PowerPC. Implemented by Adhemerval Zanella
247 and Will Schmidt.
249 * More optimized functions for SPARC. Implemented by David S. Miller.
251 * Improved support for cross-compilation, especially bootstrap builds
252 without a previously built glibc.
254 * Ports for the TILE-Gx and TILEPro families of processors. Contributed by
255 Chris Metcalf from Tilera.
257 * Support for the old ARM ABI has been removed from ports. Only the EABI is
258 now supported for ARM processors.
260 * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
261 as the name of the dynamic linker, to distinguish it from the
262 /lib/ld-linux.so.3 dynamic linker used for the base EABI.
264 * Support for CRIS has been removed from ports.
266 * A new class of installed header has been documented for low-level
267 platform-specific functionality. PowerPC added the first instance with a
268 function to provide time base register access. Contributed by Tulio
269 Magno Quites Machado Filho.
271 * ix86 configurations now install header files that are consistent with
272 what x86-64 configurations install. These same header files can be used
273 for -m32, -m64, or -mx32 builds.
274 Contributed by H.J. Lu.
276 * Math library bug fixes. A thorough audit of all open math library bugs was
277 conducted by Joseph Myers. Significant progress was made on many math
278 library bugs resulting in more accurate exceptions and function results.
279 Many thanks to all those that contributed including Andreas Jaeger for his
280 patch review and work on the x87 trigonometric instruction issues.
282 * Timezone data is no longer installed. Timezone-related binaries and scripts
283 will continue to be installed. Users should obtain their timezone data from
284 their distribution provider or from the tzdata package at
285 <ftp://munnari.oz.au/pub/>.
286 \f

364 12795, 12811, 12813, 12814, 12841
366 * The RPC implementation in libc is obsoleted. Old programs keep working
367 but new programs cannot be linked with the routines in libc anymore.
368 Programs in need of RPC functionality must be linked against TI-RPC.
369 The TI-RPC implementation is IPv6 enabled and there are other benefits.
371 Visible changes of this change include (obviously) the inability to link
372 programs using RPC functions without referencing the TI-RPC library and the
373 removal of the RPC headers from the glibc headers.
374 Implemented by Ulrich Drepper.
376 * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,
377 syncfs, setns, sendmmsg
379 * New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH,
380 yue_HK, lij_IT, mhr_RU
382 * New encodings: CP770, CP771, CP772, CP773, CP774
384 * New program sotruss to trace calls through PLTs
385 Implemented by Ulrich Drepper.
387 * The malloc hook implementation is marked deprecated and will be removed
388 from the default implementation in the next version. The design never
389 worked ever since the introduction of threads. Even programs which do
390 not create threads themselves can use multiple threads created internally.

431 Implemented by Ulrich Drepper.
433 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
434 will not be used to fill in password fields in the passwd.byname replies.
435 Instead it is used to synthesize the shadow.byname table, should it be
436 missing. This is a useful mode in some installations involving Solaris.
437 Implemented by Ulrich Drepper.
439 * New locales: kok_IN, sq_MK, cv_RU

482 * STB_GNU_UNIQUE support added.
483 Implemented by Ulrich Drepper.
485 * Implement second fallback mode for optimized DNS lookup for even more
486 broken environments. If two requests from the same port are not
487 handled correctly close the socket and open a new one before sending
488 the second request. The 'single-request-reopen' option in /etc/resolv.conf
489 can be used to select this mode right away, instead of rediscovering the
490 necessity is every process again.
491 Implemented by Ulrich Drepper.
493 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
494 Implemented by Adam Tkac.
496 * Optimized iconv conversions for S390x.

525 now in POSIX.
527 * New POSIX 2008 interface: psiginfo
528 Implemented by Ulrich Drepper.
530 * New ISO C++1x interfaces: quick_exit, at_quick_exit
531 Implemented by Ulrich Drepper.
533 * Support for selecting between multiple function definitions at runtime
534 using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper.
536 * The libcrypt library can now use the hash function implementations in
537 NSS. Implemented by Ulrich Drepper.
539 * The malloc implementation can be compiled to be less memory efficient
540 but higher performing in multi-threaded programs.
541 Implemented by Ulrich Drepper.
543 * New locales: nan_TW@latin, ks_IN
545 * Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
546 Implemented by Ulrich Drepper.
548 * Extended printf hook support. It is possible to use user-defined types
549 and extend existing format specifiers.
550 Implemented by Ulrich Drepper.
552 * Handling for group shadow files has been added.
553 Implemented by Ulrich Drepper.
555 * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
556 servers (the case, e.g., for some people using the built-in DNS
557 server in ADSL modems/routers). There is a once-per-process timeout
558 in case of a broken server. To avoid it, users can run nscd or put
559 'options single-request' in /etc/resolv.conf.
560 Implemented by Ulrich Drepper.

591 close-on-exec flag set. Implemented by Ulrich Drepper.
593 * Implement "b" mode for fmemopen. In this mode writes writes don't
594 implicitly add a NUL byte and seeks from the end of the buffer really
595 use the buffer end, not the string length as the basis.
596 Implemented by Ulrich Drepper.
598 * Many functions, exported and internal, now atomically set the close-on-exec
599 flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
601 * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
602 Sinhala)
603 Implemented by Pravin Satpute.

721 39, 68, 192, 352, 388, 531, 935, 1006, 1201, 1203, 1386, 1782, 1783, 1784,
722 1785, 1786, 1787, 1951, 1974, 1996, 2072, 2098, 2125, 2134, 2158, 2182,
723 2349, 2376, 2386, 2389, 2415, 2418, 2420, 2423, 2450, 2451, 2466, 2472,
724 2473, 2477, 2498, 2499, 2501, 2502, 2505, 2507, 2508, 2509, 2517, 2526,
725 2569, 2571, 2592, 2611, 2625, 2632, 2644, 2662, 2680, 2683, 2684, 2693,
726 2695, 2703, 2734, 2751, 2764, 2766, 2775, 2792, 2821, 2823, 2832, 2841,
727 2843, 2883, 2892, 2908, 2914, 2926, 2961, 2978, 2980, 2987, 2997, 2998,
728 3013, 3018, 3034, 3040, 3044, 3123, 3124, 3137, 3138, 3143, 3155, 3189,
729 3225, 3251, 3252, 3253, 3273
731 * For Linux, the sorting of addresses returned by getaddrinfo now also
732 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
733 Implemented by Ulrich Drepper.
735 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
736 Implemented by Ulrich Drepper.
738 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
740 * New iconv module for MIK. Contributed by Alexander Shopov.
742 * For sites with broken group and/or passwd database, the auto-propagate
743 option of nscd can prevent creating ID lookup entries from the results
744 of a name lookup and vice versa. This usually is no problem but some
745 site might have problems with the default behavior.
746 Implemented by Ulrich Drepper.
748 * Iterating over entire database in NIS can be slow. With the
749 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
750 to trade time for memory. The entire database will be read at once.
751 Implemented by Ulrich Drepper.
753 * The interfaces introduced in RFC 3542 have been implemented by
754 Ulrich Drepper.
756 * Support for the new ELF hash table format was added by Ulrich Drepper.
758 * Support for priority inheritance mutexes added by Jakub Jelinek and
759 Ulrich Drepper.
761 * Support for priority protected mutexes added by Jakub Jelinek.
763 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
764 or_IN, csb_PL, fy_NL, sr_ME.
765 \f
766 Version 2.4
768 * More overflow detection functions.
770 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
771 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
773 More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,
774 IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144,
775 IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517,
776 IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
777 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
778 by Masahide Washizawa.
780 * It is now possible to install audit libraries for the dynamic linker using
781 LD_AUDIT. Implemented by Ulrich Drepper.
783 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
784 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
785 For a libc and libpthread that works well on Linux 2.4 kernels, we
786 recommend using the stable 2.3 branch.
788 * The new function open_wmemstream acts like open_memstream,
789 but uses a wchar_t wide character buffer.
791 * The new function ppoll is an improved version of poll, similar to pselect.
793 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
794 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
795 renameat, unlinkat, linkat, symlinkat, readlinkat.
797 * New Linux kernel system calls: unshare,
798 inotify_init, inotify_add_watch, inotify_rm_watch.
800 * The euidaccess function is now also known by the alias eaccess,
801 for compatibility with some other systems.
803 * Timezone data updated to 2006b version.
804 \f
805 Version 2.3.6
807 * The following bugs are resolved with this release:
809 38, 253, 549, 622, 653, 721, 758, 851, 877, 915, 934, 955, 961,
810 1016, 1037, 1076, 1079, 1080, 1081, 1082, 1083, 1084, 1085, 1086,
811 1087, 1088, 1090, 1091, 1092, 1093, 1094, 1095, 1096, 1097, 1098,
812 1099, 1100, 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109,

814 1253, 1254, 1350, 1358, 1394, 1438, 1498, 1534
816 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
818 * As of this release, GCC 4 can be used to compile the C Library.
820 * Timezone data updated to 2005m version.
821 \f
822 Version 2.3.5
824 * The following bugs are resolved with this release:
826 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,
827 722, 723, 725, 726, 727, 728, 729, 730, 731, 732, 733, 734, 735, 736,
828 737, 738, 739, 740, 741, 742, 743, 744, 745, 765, 767, 768, 769, 776,

831 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
832 \f
833 Version 2.3.4
835 * Support for RFC 3678. Real implementations exist only for Linux so far.
836 Implemented by Ulrich Drepper.
838 * nscd can now cache entries persistently. Expiring entries are reloaded.
839 For speedups the cache can be shared in memory with client processes.
840 Implemented by Ulrich Drepper.
842 * nscd can now perform SELinux checks.
843 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
845 * getaddrinfo queries are now cached. Canonical name lookup is performed
846 efficiently.
847 Implemented by Ulrich Drepper.
849 * The nothrow function attribute is used when headers are used by gcc when
850 compiling C code. This can avoid significant amounts of exception
851 handling data.
853 * The malloc functions perform more error checking and are stricter when
854 it comes to reacting on errors. The default action is to terminate
855 the process after showing an error message. Implemented by Ulrich Drepper.
857 * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
858 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
860 * Namespaces in ld.so are implemented. DSOs can be loaded in separate
861 namespaces using the new function dlmopen(). This feature is of course,
862 like most other dynamic loading functionality, not available in statically
863 linked applications. Implemented by Ulrich Drepper.
865 * Low-overhead boundary checking variants of string and some stdio functions
866 were added. These are to be used in conjunction with a gcc patch by
867 Jakub Jelinek which adds calls to these functions if possible.
868 Implemented by Jakub Jelinek and Ulrich Drepper.
870 * Old code for several operating systems and machine architectures that
871 have not been in working condition in a long time have been removed from
872 the main source tree maintained by the GNU C Library's maintainers.
873 These files are now reside in the separate `ports' source module
874 that is usable as an add-on when building the library.
875 \f
876 Version 2.3.3
878 * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
879 interrogate the dynamic linker, compatible with the Solaris interface.
881 * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
882 implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
884 * getifaddrs now uses the netlink interface on Linux to get its information.
885 Implemented by Thorsten Kukuk.
887 * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
888 Implemented by Ulrich Drepper.
890 * support for non-executable stacks on x86 has been added. Changes mostly
891 by Roland McGrath.
893 * regex is now much faster for multibyte locales. Changes by Jakub Jelinek
894 and Ulrich Drepper.
896 * getaddrinfo now performs destination address selection according to
897 RFC 3484.
898 \f
899 Version 2.3.2
901 * Thread-safe interfaces for many functions that access locale data
902 were added in version 2.3, but these features were omitted from NEWS.
903 Many functions have variants with an `_l' suffix that take a `locale_t'
904 object as a parameter rather than consulting the current locale.
905 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
906 create and maintain `locale_t' objects. Additionally, the new function
907 `uselocale' sets "the current locale" (as used by functions not so
908 parameterized) set for an individual thread. These features were added
909 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
911 * The functions getresuid, getresgid, setresuid, and setresgid, which
912 have long been available on Linux, are now declared in <unistd.h>
913 and are now also available on the Hurd.
915 * ELF thread-local storage support (TLS) now works on x86-64.
917 * The new dynamic string token $LIB is expanded in shared library names.
918 This normally expands to lib, but on some 64-bit platforms to lib64 instead.
920 * Aldy Hernandez contributed complete software floating point support for
921 PowerPC machines with no FPU.
923 * fexecve is implemented on Linux.
925 * The `btowc' function should work at least twice as fast due to
926 specialized callbacks in the iconv modules. Implemented by Bruno Haible.
928 * With approriate thread add-ons cancelable functions are now implemented
929 in libc.so as well. No need to call the function in libpthread. This
930 change allowed to finally disable the incorrect and expensive handling
931 of weak definition in ld.so.
933 * Yet more PLT entries in libc.so have been removed. We finally arrived
934 at the bare minimum. Startup times improved appropriately.
936 * Support for the new Linux/x86 system call interface was added. The
937 AT_SYSINFO auxiliary vector entry is recognized and handled.
938 \f
939 Version 2.3
941 * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
942 charsets.
944 * iconv (the program and the interface) now accepts empty names (excluding
945 options like //TRANSLIT) to mean "use charset of current locale".
947 * localedef can now transliterate characters in strings which are not in
948 the provided charmap. The information from the input locale is used.
950 * Prelinking support was added for ELF targets. This requires additional
951 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
953 * Read-only stdio streams now use mmap to speed up operation by eliminating
954 copying and buffer underflows. To use add 'm' to the mode string of
955 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
957 * The malloc functions were completely rewritten by Wolfram Gloger based
958 on Doug Lea's malloc-2.7.0.c.
960 * Isamu Hasegawa contributed a completely new and POSIX-conformant
961 implementation of regex.
963 * Bruno Haible upgraded the iconv and locale implementation to support
964 Unicode 3.2.
966 * Contents of the LC_* and LANG environment variables in the CEN style are
967 not recognized anymore. It never was used. Change by Ulrich Drepper.
969 * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
970 thread-local storage (TLS) ABI on some platforms.
971 Changes by Ulrich Drepper. SH support by Kaz Kojima.
973 * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
974 EUC-JISX0213, and TSCII.
976 * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
977 BSD-compatible interface for getting all network interface addresses.
978 Implementation for IPv4 by Roland McGrath.
980 * Loading of locale data is faster due to the introduction of a locale
981 archive. Implemented by Roland McGrath and Ulrich Drepper.
983 * Startup times are significantly reduced by not using exported functions
984 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
985 and Ulrich Drepper.
987 * Steven Munroe contributed a port to PowerPC64/Linux.
988 \f
989 Version 2.2.6
991 * The Hurd now uses the GNU libio implementation of stdio rather than the
992 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
994 * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
995 with the same behavior as the Linux system call of the same name.
996 \f
997 Version 2.2.5
999 * Stephen Moshier implemented log2, log10, powl and cbrtl for the
1000 128-bit long double format.
1002 * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
1003 IBM1161, and IBM1162 charsets.
1005 * Andreas Jaeger contributed a port to x86-64/Linux.
1007 * Peter Bruin contributed a port to PowerPC/Hurd.
1009 * libc functions using I/O streams now can handle wide-oriented streams
1010 as well.
1012 * optimizations in the dynamic linker. Binaries created by recent binutils
1013 versions start up quicker due to reduced time spent on relocations.
1015 * Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
1016 \f
1017 Version 2.2.4
1019 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
1020 asinh, atanh, j0 for the 128-bit long double format.
1022 * Bruno Haible updated all the code handling Unicode in some form to
1023 support Unicode 3.1.
1025 * Speed of regex for single-byte locales is back to previous levels.
1026 Patch by Isamu Hasegawa.
1028 * Alpha, SPARC, and IA-64 now also using floating stacks.
1030 * Startup time of internationalized applications greatly improved through
1031 iconv cache. Use iconvconfig to generate the cache file.
1032 Contributed by Ulrich Drepper.
1034 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
1035 severe performance problems. Patch by David Mosberger.
1037 * The Hurd port got a lot more functionality like AIO, various stdio
1038 extensions, etc. Mainly done by Roland McGrath.
1040 * mtrace can now lookup symbols in shared libraries.
1041 \f
1042 Version 2.2.3
1044 * Intel's IA-64 math library is largely integrated. It provides fast and
1045 accurate implementatations for most basic and standard math functions
1046 in float, double, and long double format.
1048 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
1049 and asin for the 96-bit long double format and asin, log, tan for the
1050 128-bit long double format.
1052 * The beginning of a last-bit accurate math library by IBM Haifa were added.
1053 The basic double functions exist today. Contributed by Abraham Ziv
1054 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
1055 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
1057 * An asynchronous name lookup library was added. The interface is designed
1058 after POSIX AIO. The proposal was circulated beforehand to get comments.
1059 No negative ones came in. Implemented by Ulrich Drepper.
1061 * Port to S390/64bit contributed by Martin Schwidefsky
1062 <schwidefsky@de.ibm.com>.
1064 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
1065 of functions for Linux/IA-64.
1067 * The RPC code is now thread safe. Threads can now use the same service
1068 of different services at the same time. Patch by Eric Norum
1069 <eric.norum@usask.ca> with some help by Ulrich Drepper.
1071 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
1072 family of functions for Linux/S390.
1074 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
1075 of functions for Linux/x86.
1077 * Port to Linux/CRIS contributed by Axis Communications.
1078 \f
1079 Version 2.2.2
1081 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
1082 we can now check for namespace violations and missing declarations. The
1083 result is that almost all headers are now Unix-compliant (as defined in
1084 the upcoming XPG6). The negative side is that some programs might need
1085 corrections, too, if they depend on the incorrect form of the headers in
1086 previous versions which defined too many symbols and included too many
1087 other headers.
1089 * regex now handles multibyte character sets correctly.
1090 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
1092 * iconv (the program) does now conform to the upcoming XPG6 and handles
1093 charmaps. Instead of the charset names the path of charmaps can be
1094 provided and the conversion happens based on this data.
1095 Contributed by Ulrich Drepper.
1097 * The locale program now provides detailed information about the installed
1098 locales. While
1100 locale -a
1102 only lists the names of the supported locales
1104 locale -a --verbose
1106 provides details such as country, language, and codeset name.
1107 Contributed by Ulrich Drepper.
1108 \f
1109 Version 2.2.1
1111 * The gencat program now parses the input file according to the charset
1112 selected by the LC_CTYPE category. This is important for stateful
1113 character sets. To make generating catalogs easier there is a way
1114 to overwrite the charset selected by the locale: before the first
1115 message or $ quote line the catalog can contain a line like
1117 $ codeset=ISO-8859-2
1119 to select the charset (ISO-8859-2 in this case).
1121 Implemented by Shinya Hanataka and Ulrich Drepper.
1123 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
1124 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
1125 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
1127 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
1128 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
1130 * The LANGUAGE environment variable is now ignored unless the locale is
1131 changed from the default "C" locale.
1133 * The usual bug fixes.
1134 \f
1135 Version 2.2
1137 * Greg McGary added runtime support for bounds checking using gcc's
1138 new -fbounded-pointers option. ix86 target is complete. PowerPC
1139 is in progress.
1141 * Thorsten Kukuk added secure mode support to nscd.
1143 * The Berkeley db libraries have been removed.
1145 Related, the nss_db module is now in a separate package since it
1146 obviously requires a database library being available.
1148 * Wide character I/O streams implemented by Ulrich Drepper.
1150 * Functions from the extended socket API added by Ulrich Drepper.
1152 * Functions feenableexcept and fedisableexcept to control the
1153 behaviour of individual exceptions have been added by Andreas Jaeger.
1155 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
1157 * The resolver code has been updated from bind 8.2.3-T5B which supports
1158 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
1159 and Mark Kettenis.
1161 This change could in some situations effect backward compatibility. Since
1162 now `_res' is a thread-local instead of a global variable, modifying it
1163 in one thread does not have any effect in other threads.
1165 The resolver library was also extended to allow IPv6 as the transport
1166 protocol for the requests. This work was done by Stig Venaas.
1168 * Compatibility code for K&R C compilers has been removed from the
1169 header files. A ISO C compiler is needed to use the library
1170 (conforming to either C89 or C99 standard).
1172 * Complete rewrite of the localedef program to support multibyte character
1173 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
1174 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
1175 Implemented by Ulrich Drepper.
1177 Bruno Haible significantly improved the generation and use of the data
1178 structures for the wide character tables.
1180 * Plural handling in gettext implemented by Ulrich Drepper.
1182 * The utmp daemon has been removed.
1184 * The port to MIPS-Linux has been finished by Andreas Jaeger.
1186 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
1187 and Yutaka Niibe.
1189 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
1191 * POSIX barriers implemented by Kaz Kylheku.
1193 * POSIX spawn function family implemented by Ulrich Drepper.
1195 * POSIX spinlocks are now available.
1197 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
1199 * the configure option --enable-kernel=X.Y.Z allows to strip out
1200 compatibility for kernel versions before X.Y.Z. This is currently only
1201 implemented for Linux.
1203 * the sockaddr_in6 structure changed. The IPv6 working group added a new
1204 field sin6_scope_id. This means that all programs using IPv6 should be
1205 recompiled. Don't expect binary compatibility with previous glibc
1206 versions.
1208 * various conversion modules for IBM character sets contributed by
1209 Masahide Washizawa.
1211 * IA-64 port by Jes Sorensen and HJ Lu.
1212 \f
1213 Version 2.1.3
1215 * bug fixes
1217 \f
1218 Version 2.1.2
1220 * bug fixes
1222 \f
1223 Version 2.1.1
1225 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
1227 * New xdr functions are added; some rpc functions are now 64bit clean.
1229 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
1231 * Fixed known incompatibilities with glibc 2.0.
1233 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
1235 * Optimized a number of functions (especially the ELF dynamic loader).
1237 * Update timezone data files.
1239 * lots of charmaps corrections
1241 * some new locale definitions and charmaps
1243 \f
1244 Version 2.1
1246 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
1247 conform to POSIX member type requirements. Symbol versions have been
1248 adjusted as needed within the library, and for direct use by applications,
1249 but there is potential for problems if third-party libraries use
1250 struct timeval as part of their interface. This does not present
1251 a problem for X and other "essential" system libraries.
1253 * An additional locale model to support C++ Standard Library locale
1254 model and probably more was implemented by Ulrich Drepper.
1256 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
1257 symbol level.
1259 * Miles Bader provided the `argp' function family to support hierachical
1260 command line argument parsing, layered on top of getopt.
1262 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
1264 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
1265 numbers.
1267 * scanf recognizes the %a and %A format for scanning floating point numbers.
1269 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
1270 information and interfaces for the available integer types.
1272 * about 130 new math functions were added to implement the ISO C9x math
1273 library.
1275 * the new header <complex.h> contains definitions of the complex math
1276 functions from ISO C 9X.
1278 * the new header <tgmath.h> defines generic macros to use complex or
1279 real valued functions.
1281 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
1283 * Andreas Jaeger provided a test suite for the math library.
1285 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
1287 * Ulrich Drepper added character set conversion functions (iconv).
1289 * Optimized string functions have been added.
1291 * The localedata addon is now part of glibc.
1293 * An implementation of profiling shared libraries was added by Ulrich Drepper.
1295 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
1296 daemon for NSS (nscd).
1298 Missing a better place here are some numbers on improvements. Under
1299 Linux 2.1.125 un-tar-ing the kernel sources takes
1301 user system wall
1303 using local files 12.19s 6.88s 22.91s
1305 using NIS 13.92s 8.91s 26.34s
1307 using NIS & nscd 10.37s 7.34s 25.30s
1309 using NIS+ 27.57s 30.37s 640.46s
1311 using NIS+ & nscd 10.25s 7.83s 26.51s
1313 using NIS & old nscd [1] 13.83s 8.32s 29.60s
1315 Keep in mind that non-namelookup related operations dominate above times.
1316 It was just a common complain that using NIS+ unpacking the kernel is
1317 horribly slow.
1319 [1] The old nscd implementation is not available anymore since it was
1320 distributed with glibc up to version 2.0.98 and thus is now replaced.
1322 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
1324 * Mark Kettenis provided a Hesiod NSS module.
1326 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
1327 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
1329 * rcmd can now handle netgroups (Dick Streefland).
1331 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
1332 Bambrough.
1334 * Support for the IPv6 protocol has been added to the socket API, as per the
1335 latest draft standards.
1337 * Support for Linux 2.2 has been added.
1339 * Interface changes relative to the latest 2.0.x release:

1710 * fixed lots of header problems (especially Linux/GNU specific)
1712 * dynamic loader preserves all registers
1714 * Roland McGrath provided support for handling of auxiliary objects in
1715 the ELF dynamic loader.
1717 * support for parallel builds is improved
1718 \f
1719 Version 2.0
1721 * GNU extensions are no longer declared by default. To enable them you
1722 must define the macro `_GNU_SOURCE' in your program or compile with
1723 `-D_GNU_SOURCE'.
1725 * The library has changed from using GNU ld symbol aliases to using weak
1726 symbols where available. The ELF object file format supports weak
1727 symbols; GNU ld also supports weak symbols in the a.out format. (There
1728 is also now support for other GNU ld extensions in ELF. Use the
1729 `--with-elf' option to configure to indicate you have ELF, and
1730 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
1731 of many files which contained only symbol aliases, reducing the size of
1732 the source and the compiled library; many other files were renamed to
1733 less cryptic names previously occupied by the symbol alias files.
1734 There is a new header file <elf.h> for programs which operate on
1735 files in the ELF format.
1737 * Converted to Autoconf version 2, so `configure' has more options.
1738 Run `configure --help' to see the details.
1740 * The library can now be configured to build profiling, highly-optimized
1741 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1742 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1743 `configure' enable building these extra libraries. The shared library is
1744 built by default when using both ELF and GNU ld. When shared libraries
1745 are enabled, the new library `-ldl' is available for arbitrary run-time
1746 loading of shared objects; its interface is defined in <dlfcn.h>. The
1747 new header file <link.h> gives access to the internals of the run-time
1748 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1749 application of same name on other systems and it provides information
1750 about dynamically linked binaries.
1752 * The C library now provides the run-time support code for profiling
1753 executables compiled with `-pg'. Programs can control the profiling code
1754 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1755 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1756 the support for this file format was contributed by David Mosberger-Tang.
1758 * The math code has been replaced with a math library based on fdlibm from
1759 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1760 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1761 functions. The math functions now reside in a separate library, so
1762 programs using them will need to use `-lm' their linking commands.
1764 * John C. Bowman contributed optimized ix87 assembler inline functions.
1766 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1767 mechanism similar to that found in Solaris 2. This is now used for the
1768 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1769 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1770 file controls what services are used for each individual database. This
1771 works by loading shared libraries with names specified in `nsswitch.conf',
1772 so service modules can be changed or added at any time without even
1773 relinking any program. Currently there are the file, db, and NIS based
1774 NSS services available.
1776 * The new functions `strtoq' and `strtouq' parse integer values from
1777 strings, like `strtol' and `strtoul', but they return `long long int' and
1778 `unsigned long long int' values, respectively (64-bit quantities).
1780 * The new functions `strtof' and `strtold' parse floating-point values from
1781 strings, like `strtod', but they return `float' and `long double' values,
1782 respectively (on some machines `double' and `long double' are the same).
1784 * Ulrich Drepper has contributed new implementations of the floating-point
1785 printing and reading code used in the `printf' family of functions and
1786 `strtod', `strtof', and `strtold'. These new functions are perfectly
1787 accurate, and much faster than the old ones.
1789 * The implementation of the POSIX locale model was completely rewritten by
1790 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1791 to compile the POSIX locale definition.
1793 * The former dummy implementations of the strcoll and strxfrm function are
1794 now replaced by fully functional code contributed by Ulrich Drepper. The
1795 collation information comes from the POSIX locale definitions.
1797 * The new header <langinfo.h> defines an interface for accessing
1798 various locale-dependent data (using the locale chosen with `setlocale').
1800 * Ulrich Drepper has contributed a new suite of functions for operation on
1801 wide-character and multibyte-character strings, in <wchar.h>;
1802 and classification and case conversion of wide characters, in <wctype.h>.
1803 These new functions are conforming to the ISO C, Amendement 1 specification.
1805 * There is now a second implementation of the standard I/O library available.
1806 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1807 by Hongjiu Lu and made thread safe by Ulrich Drepper.
1809 * You can now use positional parameter specifications in format strings
1810 for the `printf' and `scanf' families of functions. For example,
1811 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1812 ``Number 6, Mr Jones''. This is mainly useful when providing different
1813 format strings for different languages, whose grammars may dictate
1814 different orderings of the values being printed. To support this
1815 feature, the interface for `register_printf_handler' has changed; see
1816 the header file <printf.h> for details.
1818 * The `printf' and `scanf' families of functions now understand a new
1819 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1820 to group numbers as indicated by the locale; for `scanf' and friends, this
1821 says to accept as valid only a number with all the proper grouping
1822 separators in the right places. In the default "C" locale, numbers are
1823 not grouped; but locales for specific countries will define the usual
1824 conventions (i.e. separate thousands with `,' in the US locale).
1826 * The pgrp functions have been regularized, slightly incompatibly but much
1827 less confusingly. The core functions are now `getpgid' and `setpgid',
1828 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1829 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1830 provided for compatibility. There is no longer an incompatible `getpgrp'
1831 with an argument declared under _BSD_SOURCE; no BSD code uses it.
1833 * The new header file <fts.h> and suite of functions simplify programs that
1834 operate on directory trees. This code comes from 4.4 BSD.
1836 * The resolver code has been updated from the BIND 4.9.5-P1 release.
1837 Parts of the code were heavily modified by Ulrich Drepper to fit in the
1838 NSS scheme used in glibc.
1840 * There is a new malloc debugging hook `__memalign_hook'.
1842 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
1843 `unsigned int' in <sys/types.h>. These are for compatibility only and
1844 their use is discouraged.
1846 * The `-lmcheck' library to enable standard malloc debugging hooks is now
1847 done differently, so that it works even without GNU ld.
1849 * New function `euidaccess' checks allowed access to a file like `access',
1850 but using the effective IDs instead of the real IDs.
1852 * The time zone data files have been updated for the latest and greatest
1853 local time conventions of the countries of the world.
1855 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
1856 see <dirent.h>.
1858 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
1859 for formatting floating-point numbers. They are provided only for
1860 compatibility; new programs should use `sprintf' instead. There are
1861 also equivalent function for the `long double' floating-point type and
1862 all functions also exist in a reentrant form.
1864 * The new auxiliary library `-lutil' from 4.4 BSD contains various
1865 functions for maintaining the login-record files (primarily of use to
1866 system programs such as `login'), and convenient functions for
1867 allocating and initializing a pseudo-terminal (pty) device.
1869 * Ulrich Drepper has contributed new support for System V style
1870 shared memory and IPC on systems that support it.
1872 * Ulrich Drepper has contributed several miscellaneous new functions found
1873 in System V: The `hsearch' family of functions provide an effective
1874 implementation of hash tables; `a64l' and `l64a' provide a very simple
1875 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
1876 number generator.
1878 * Ulrich Drepper has contributed new reentrant counterparts for the
1879 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
1881 * Ulrich Drepper has contributed new, highly-optimized versions of several
1882 string functions for the i486/Pentium family of processors.
1884 * Ulrich Drepper has updated the Linux-specific code, based largely
1885 on work done in Hongjiu Lu's version of GNU libc for Linux.
1886 The GNU library now supports Linux versions 2.0.10 and later,
1887 using the ELF object file format (i[3456]86-*-linux).
1889 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
1891 * David Mosberger-Tang and Richard Henderson have ported the C library
1892 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
1893 dynamic linking support for ELF/Alpha.
1895 * Richard Henderson contributed several Alpha optimized assembler function
1896 for arithmetic and string handling.
1898 * Ulrich Drepper has contributed a new set of message catalog functions to
1899 support multiple languages using the <libintl.h> interface, for use with
1900 his new package GNU gettext. Translation volunteers have contributed
1901 catalogs of the library's messages in Spanish, German, and Korean.
1903 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
1904 program and the `catgets' function for reading the catalog files it
1905 creates. (The <libintl.h> interface is preferred; we include the
1906 <nl_types.h> interface using `catgets' only for source compatibility with
1907 programs already written to use it.)
1909 * New header file <values.h> gives SVID-compatible names for <limits.h>
1910 constants.
1912 * Various new macros, declarations, and small header files for compatibility
1913 with 4.4 BSD.
1915 * New function `group_member' is a convenient way to check if a process has
1916 a given effective group ID.
1918 * When using GCC 2.7 and later, the socket functions are now declared in a
1919 special way so that passing an argument of type `struct sockaddr_in *',
1920 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
1921 `struct sockaddr *' type, does not generate a type-clash warning.
1923 * New function `error' declared in header file <error.h> is a convenient
1924 function for printing error messages and optionally exiting; this is the
1925 canonical function used in GNU programs. The new functions `err', `warn',
1926 and friends in header file <err.h> are the canonical 4.4 BSD interface for
1927 doing the same thing.
1929 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
1930 POSIX.2 `glob' function to do ~ and {...} expansion.
1932 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
1933 `clearenv' which is used in POSIX.9 is also available.
1935 * New function `getsid' returns session ID number on systems that support it.
1937 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1938 files <db.h> and <mpool.h> provide a rich set of functions for several
1939 types of simple databases stored in memory and in files, and <ndbm.h> is
1940 an old `ndbm'-compatible interface using the `db' functions. Link with
1941 `-ldb' to get these functions.
1943 * New macro `strdupa' copies a string like `strdup', but uses local stack
1944 space from `alloca' instead of dynamic heap space from `malloc'.
1946 * New function `strnlen' is like `strlen' but searches only a given maximum
1947 number of characters for the null terminator. `stpncpy', `strndup' and
1948 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1949 function.
1951 * New function `statfs' in header <sys/statfs.h>.
1953 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1954 provide convenient functions for operating on blocks of null-terminated
1955 strings.
1957 * A new suite of functions in <utmp.h> handle all the details of reading
1958 and writing the utmp file.
1960 * An implementation of the NIS/YP(tm) based NSS service was contributed by
1961 Thorsten Kukuk.
1963 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1964 completely POSIX compliant and also implemented the extended functionality
1965 to handle alternate digit representation and alternate era date formats.
1967 * Ulrich Drepper provided an implementation of the `strptime' function
1968 defined in XPG4.2 which transforms a string into a `struct tm' value.
1970 * Paul Eggert provided the tzselect shell script as part of the timezone
1971 code. The shell script makes it easy to select the correct timezone
1972 specification.
1974 * The implementation of the malloc family of functions is completely replaced
1975 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1976 The implementation uses the mmap function (if available) and it is
1977 optimized for the use in multi threaded programs.
1979 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1980 functions. This new functionality is usable by specifying a special
1981 salt string and it is compatible with implementation on *BSD systems.
1983 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1984 `getsubopt' to handle second level command line options, `bsd_signal'
1985 to access BSD style `signal' functionality, the obsolete `regexp' style
1986 expression matcher.
1988 * the `lchown' function is available on system which support this
1989 functionality.
1991 * The implementation of the shadow password handling function was contributed
1992 by Ulrich Drepper.
1994 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1996 * POSIX.1g support was added. The <sys/select.h> header is available,
1997 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1998 implementation of `getaddrinfo'.
1999 \f
2000 Version 1.09
2002 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
2004 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
2005 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
2007 * The new function `daemon' from 4.4 BSD is useful for server programs that
2008 want to put themselves in the background.
2010 * Joel Sherrill has contributed support for several standalone boards that
2011 run without an operating system.
2013 * `printf', `scanf' and friends now accept a `q' type modifier for long
2014 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
2016 * All of the code taken from BSD (notably most of the math and networking
2017 routines) has been updated from the BSD 4.4-Lite release.
2019 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
2021 * The new functions `getdomainname' and `setdomainname' fetch or change the
2022 YP/NIS domain name. These are system calls which exist on systems which
2023 have YP (aka NIS).
2025 * The time zone data files have been updated for the latest international
2026 conventions.
2028 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
2029 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
2030 \f
2031 Version 1.08
2033 * The C library now includes support for Sun RPC, from Sun's free
2034 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
2035 are included. (There is still no support for YP.)
2037 * Tom Quinn has contributed a port of the C library to SGI machines running
2038 Irix 4 (mips-sgi-irix4).
2040 * The new `lockf' function is a simplified interface to the locking
2041 facilities of `fcntl', included for compatibility.
2043 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
2045 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
2047 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
2048 compatibility.
2050 * The error message printed by `assert' for a failed assertion now includes
2051 the name of the program (if using GNU ld) and the name of the calling
2052 function (with versions of GCC that support this).
2054 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
2056 * The library now includes the <sys/mman.h> header file and memory
2057 management functions `mmap', `munmap', `mprotect', `msync', and
2058 `madvise', on systems that support those facilities.
2060 * The interface for `mcheck' has changed slightly: the function called to
2061 abort the program when an allocation inconsistency is detected now takes
2062 an argument that indicates the type of failure. The new function
2063 `mprobe' lets you request a consistency check for a particular block at
2064 any time (checks are normally done only when you call `free' or `realloc'
2065 on a block).
2067 * It is now possible to easily cross-compile the C library, building on one
2068 system a library to run on another machine and/or operating system. All
2069 you need to do is set the variable `HOST_CC' in `configparms' to the
2070 native compiler for programs to run on the machine you are building on (a
2071 few generator programs are used on Unix systems); set `CC' to the
2072 cross-compiler.
2074 * The new function `fexecve' (only implemented on the GNU system) executes
2075 a program file given a file descriptor already open on the file.
2076 \f
2077 Version 1.07
2079 * Brendan Kehoe has contributed most of a port to the DEC Alpha
2080 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
2082 * You can set the variable `libprefix' in `configparms' to specify a prefix
2083 to be prepended to installed library files; this makes it easy to install
2084 the GNU C library to be linked as `-lgnuc' or whatever.
2086 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
2087 copies a limited number of characters from a string, and returns the
2088 address of the last character written.
2090 * You no longer need to check for whether the installed `stddef.h' is
2091 compatible with the GNU C library. configure now checks for you.
2093 * You can now define a per-stream `fileno' function to convert the
2094 stream's cookie into an integral file descriptor.
2096 * ``malloc (0)'' no longer returns a null pointer. Instead, it
2097 allocates zero bytes of storage, and returns a unique pointer which
2098 you can pass to `realloc' or `free'. The behavior is undefined if
2099 you dereference this pointer.
2101 * The C library now runs on Sony NEWS m68k machines running either
2102 NewsOS 3 or NewsOS 4.
2104 * The new `syscall' function is a system-dependent primitive function
2105 for invoking system calls. It has the canonical behavior on Unix
2106 systems, including unreliable return values for some calls (such as
2107 `pipe', `fork' and `getppid').
2109 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
2110 to `EAGAIN', which is the preferred name. On systems whose kernels
2111 use two distinct codes, the C library now translates EWOULDBLOCK to
2112 EAGAIN in every system call function.
2113 \f
2114 Version 1.06
2116 * The GNU C Library Reference Manual is now distributed with the library.
2117 `make dvi' will produce a DVI file of the printed manual.
2118 `make info' will produce Info files that you can read on line using C-h i
2119 in Emacs or the `info' program.
2120 Please send comments on the manual to bug-glibc-manual@gnu.org.
2122 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
2124 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
2126 * Jason Merrill has contributed a port to the Sequent Symmetry running
2127 Dynix version 3 (i386-sequent-dynix).
2129 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
2130 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
2132 * New function `memory_warnings' lets you arrange to get warnings when
2133 malloc is running out of memory to allocate, like Emacs gives you.
2135 * The C library now contains the relocating allocator used in Emacs 19 for
2136 its editing buffers. This allocator (ralloc) minimizes allocation
2137 overhead and fragmentation by moving allocated regions around whenever it
2138 needs to. You always refer to a ralloc'd region with a "handle" (a
2139 pointer to a pointer--an object of type `void **').
2141 * There is a new `printf' format: `%m' gives you the string corresponding
2142 to the error code in `errno'.
2144 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
2145 or `%[' conversion, but instead of filling in a fixed-sized buffer you
2146 pass, the `a' modifier says to fill in a `char **' you pass with a
2147 malloc'd string.
2149 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
2150 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
2151 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
2153 * `mkstemp' is a traditional Unix function to atomically create and open a
2154 uniquely-named temporary file.
2155 \f
2156 Version 1.05
2158 * The standard location for the file that says what the local timezone is
2159 has changed again. It is now `/usr/local/etc/localtime' (or more
2160 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
2162 * The distribution no longer contains any files with names longer than 14
2163 characters.
2165 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
2166 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
2168 * New functions `ttyslot' and `syslog' from 4.4 BSD.
2169 \f
2170 Version 1.04
2172 * The configuration process has changed quite a bit. The `configure'
2173 script is now used just like the configuration scripts for other GNU
2174 packages. The `sysdeps' directory hierarchy is much rearranged.
2175 The file `INSTALL' explains the new scheme in detail.
2177 * The header files no longer need to be processed into ANSI C and
2178 traditional C versions. There is just one set of files to install, and
2179 it will work with ANSI or old C compilers (including `gcc -traditional').
2181 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
2182 MIPS DECStation running Ultrix 4.
2184 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
2185 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
2186 made itself into a shared library.
2188 * Yet further improved support for the i386, running 4.3 BSD-like systems
2189 (such as Mach 3 with the Unix single-server), or System V.
2191 * New function `strncasecmp' to do case-insensitive string comparison
2192 with limited length.
2194 * New function `strsep' is a reentrant alternative to `strtok'.
2196 * New functions `scandir' and `alphasort' for searching directories.
2198 * New function `setenv' is a better interface to `putenv'.
2200 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
2201 function for traversing a directory tree.
2203 * The GNU obstack package is now also part of the C library.
2204 The new function `open_obstack_stream' creates a stdio stream that
2205 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
2206 formatted output directly to an obstack.
2208 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
2209 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
2211 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
2213 * The new functions `strfry' and `memfrob' do mysterious and wonderful
2214 things to your strings.
2216 * There are some new test programs: test-fseek, testmb, and testrand.
2218 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
2219 These ports are not finished, but are a good starting place for really
2220 supporting those systems.
2222 * `/etc/localtime' is now the standard location for the file that says what
2223 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
2224 This follows the general principle that `/etc' is the place for all local
2225 configuration files.
2227 * The C library header files now use `extern "C"' when used by the C++
2228 compiler, so the C library should now work with C++ code.
2230 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
2231 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
2232 in <strings.h>.)
2234 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
2235 function which uses the `merge sort' algorithm, and is said to be
2236 significantly faster than the old GNU `qsort' function. Merge sort is
2237 now the standard `qsort' function. The new algorithm can require a lot
2238 of temporary storage; so, the old sorting function is called when the
2239 required storage is not available.
2241 * The C library now includes Michael Glad's Ultra Fast Crypt, which
2242 provides the Unix `crypt' function, plus some other entry points.
2244 * The code and header files taken from 4.4 BSD have been updated with the
2245 latest files released from Berkeley.
