8 Version 2.18
10 * The following bugs are resolved with this release:
12 2546, 2560, 5159, 6809, 7006, 10060, 10062, 10283, 10357, 10686, 11120,
13 11561, 12310, 12387, 12492, 12515, 12723, 13550, 13889, 13951, 13988,
14 14142, 14176, 14200, 14256, 14280, 14293, 14317, 14327, 14478, 14496,
15 14582, 14686, 14812, 14888, 14894, 14907, 14908, 14909, 14920, 14952,
16 14964, 14981, 14982, 14985, 14991, 14994, 14996, 15000, 15003, 15006,
17 15007, 15014, 15020, 15022, 15023, 15036, 15054, 15055, 15062, 15078,
18 15084, 15085, 15086, 15100, 15160, 15214, 15221, 15232, 15234, 15283,
19 15285, 15287, 15304, 15305, 15307, 15309, 15327, 15330, 15335, 15336,
20 15337, 15339, 15342, 15346, 15359, 15361, 15366, 15380, 15381, 15394,
21 15395, 15405, 15406, 15409, 15416, 15418, 15419, 15423, 15424, 15426,
22 15429, 15431, 15432, 15441, 15442, 15448, 15465, 15480, 15485, 15488,
23 15490, 15492, 15493, 15497, 15506, 15529, 15536, 15553, 15577, 15583,
24 15618, 15627, 15631, 15654, 15655, 15666, 15667, 15674, 15711, 15755.
26 * CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
27 has been fixed by disabling the use of pt_chown (Bugzilla #15755).
28 Distributions can re-enable building and using pt_chown via the new configure
29 option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
30 considerable security risks and should only be used if the distribution
31 understands and accepts the risks.
33 * CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
34 #15078).
36 * CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
37 fixed (Bugzilla #15330).
39 * Add support for calling C++11 thread_local object destructors on thread
40 and program exit. This needs compiler support for offloading C++11
41 destructor calls to glibc.
43 * Improved worst case performance of libm functions with double inputs and
44 output.
46 * Support for priority inherited mutexes in pthread condition variables on
47 non-x86 architectures.
49 * Port to Xilinx MicroBlaze contributed by David Holsgrove.
51 * Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
53 * Optimized string functions for ARM. Implemented by Will Newton and
54 Richard Henderson.
56 * Optimized libm functions for SPARC. Implemented by David S. Miller.
58 * Support for building more of ARM glibc as Thumb-2 code. Implemented by
59 Richard Henderson.
61 * Support for building most of MIPS glibc as MIPS16 code. Implemented by
62 Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
64 * Added a benchmark framework to track performance of functions in glibc.
66 * New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
67 It is based on draft TS 18661 and currently enabled as a GNU extension.
69 * On Linux, the clock function now uses the clock_gettime system call
70 for improved precision, rather than old times system call.
72 * Added new API functions pthread_getattr_default_np and
73 pthread_setattr_default_np to get and set the default pthread
74 attributes of a process.
76 * Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
77 This may improve lock scaling of existing programs on TSX capable systems.
78 When the --enable-lock-elision=yes parameter is specified at configure
79 time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
80 mutexes.

82 Version 2.17
84 * The following bugs are resolved with this release:
86 1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808,
87 9685, 9914, 10014, 10038, 10114, 10191, 10631, 10873, 11438, 11607, 11638,
88 11741, 12140, 13013, 13412, 13542, 13601, 13603, 13604, 13629, 13679,
89 13696, 13698, 13717, 13741, 13759, 13761, 13763, 13881, 13939, 13950,
90 13952, 13966, 14042, 14047, 14090, 14150, 14151, 14152, 14154, 14157,
91 14166, 14173, 14195, 14197, 14237, 14246, 14251, 14252, 14283, 14298,
92 14303, 14307, 14328, 14331, 14336, 14337, 14347, 14349, 14368, 14376,
93 14417, 14447, 14459, 14476, 14477, 14501, 14505, 14510, 14516, 14518,
94 14519, 14530, 14532, 14538, 14543, 14544, 14545, 14557, 14562, 14568,
95 14576, 14579, 14583, 14587, 14595, 14602, 14610, 14621, 14638, 14645,
96 14648, 14652, 14660, 14661, 14669, 14672, 14683, 14694, 14716, 14719,
97 14743, 14767, 14783, 14784, 14785, 14793, 14796, 14797, 14801, 14803,
98 14805, 14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833,
99 14835, 14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872,
100 14879, 14889, 14893, 14898, 14914.
102 * Optimization of memcpy for MIPS.
104 * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
105 EMFILE has been fixed (Bugzilla #14889).
107 * The add-on ports collection is now distributed in the "ports" subdirectory
108 of the main GNU C Library distribution, rather than separately.
110 * Port to ARM AArch64 contributed by Linaro.
112 * Support for STT_GNU_IFUNC symbols added for s390 and s390x.
113 Optimized versions of memcpy, memset, and memcmp added for System z10 and
114 zEnterprise z196.
115 Implemented by Andreas Krebbel.
117 * The new function secure_getenv allows secure access to the environment,
118 returning NULL if running in a SUID/SGID process. This function replaces
119 the internal function __secure_getenv.
121 * SystemTap static probes have been added into the dynamic linker.
122 Implemented by Gary Benson.
124 * Optimizations of string functions strstr, strcasestr and memmem.
125 Implemented by Maxim Kuvyrkov.
127 * The minimum Linux kernel version that this version of the GNU C Library
128 can be used with is 2.6.16.
130 * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
131 powerpc POWER7. Implemented by Will Schmidt.
133 * New configure option --disable-nscd builds the C library such that it
134 never attempts to contact the Name Service Caching Daemon (nscd).
135 New configure option --disable-build-nscd avoids building nscd itself;
136 this is the default if --disable-nscd is used.
138 * Improved support for cross-compilation, including cross-testing and
139 bootstrap builds without a previously built glibc.
141 * Several testsuite tests are now able to test multiple IFUNC variants of an
142 interface, rather than just testing the one that would be chooen by
143 default.
145 * New configure options --with-bugurl and --with-pkgversion, for
146 distributors to use to embed their bug-reporting and package version
147 information in --help and --version output.
149 * The ttyname and ttyname_r functions on Linux now fall back to searching for
150 the tty file descriptor in /dev/pts or /dev if /proc is not available. This
151 allows creation of chroots without the procfs mounted on /proc.
153 * The `crypt' function now fails if passed salt bytes that violate the
154 specification for those values. On Linux, the `crypt' function will
155 consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
156 enabled, and fail on encrypted strings using the MD5 or DES algorithm
157 when the mode is enabled.
159 * The `clock_*' suite of functions (declared in <time.h>) is now available
160 directly in the main C library. Previously it was necessary to link with
161 -lrt to use these functions. This change has the effect that a
162 single-threaded program that uses a function such as `clock_gettime' (and
163 is not linked with -lrt) will no longer implicitly load the pthreads
164 library at runtime and so will not suffer the overheads associated with
165 multi-thread support in other code such as the C++ runtime library.
167 * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
168 sat_IN, and szl_PL.
169 \f
170 Version 2.16
172 * The following bugs are resolved with this release:
174 174, 208, 350, 369, 411, 706, 766, 887, 2074, 2541, 2547, 2548, 2550,
175 2551, 2552, 2553, 2554, 2562, 2563, 2565, 2566, 2570, 2576, 2636, 2678,
176 3335, 3440, 3748, 3768, 3866, 3868, 3906, 3976, 3992, 4026, 4108, 4596,

182 13058, 13223, 13361, 13525, 13526, 13527, 13528, 13529, 13530, 13531,
183 13532, 13533, 13547, 13551, 13552, 13553, 13555, 13556, 13559, 13563,
184 13566, 13576, 13579, 13583, 13592, 13594, 13613, 13618, 13637, 13656,
185 13658, 13673, 13691, 13695, 13704, 13705, 13706, 13718, 13726, 13738,
186 13739, 13743, 13750, 13758, 13760, 13761, 13775, 13786, 13787, 13792,
187 13806, 13824, 13840, 13841, 13844, 13846, 13848, 13851, 13852, 13854,
188 13871, 13872, 13873, 13879, 13882, 13883, 13884, 13885, 13886, 13892,
189 13895, 13908, 13910, 13911, 13912, 13913, 13914, 13915, 13916, 13917,
190 13918, 13919, 13920, 13921, 13922, 13923, 13924, 13926, 13927, 13928,
191 13938, 13941, 13942, 13954, 13955, 13956, 13963, 13967, 13968, 13970,
192 13973, 13979, 13983, 13986, 13996, 14012, 14027, 14033, 14034, 14036,
193 14040, 14043, 14044, 14048, 14049, 14050, 14053, 14055, 14059, 14064,
194 14075, 14080, 14083, 14103, 14104, 14109, 14112, 14117, 14122, 14123,
195 14134, 14153, 14183, 14188, 14199, 14210, 14218, 14229, 14241, 14273,
196 14277, 14278.
198 * Support for the x32 ABI on x86-64 added. The x32 target is selected by
199 configuring glibc with:
200 BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
201 Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
202 Implemented by H.J. Lu.
204 * ISO C11 support:
206 + define static_assert
208 + do not declare gets
210 + declare at_quick_exit and quick_exit also for ISO C11
212 + aligned_alloc. NB: The code is deliberately allows the size parameter
213 to not be a multiple of the alignment. This is a moronic requirement
214 in the standard but it is only a requirement on the caller, not the
215 implementation.
217 + timespec_get added
219 + uchar.h support added
221 + CMPLX, CMPLXF, CMPLXL added
223 Implemented by Ulrich Drepper.
225 * Support for the IA-64 has been moved to ports.
227 * Remove support for anything but ELF binary format
229 * Checking versions of poll, ppoll added.
230 Implemented by Ulrich Drepper.
232 * More generic and 64-bit performance optimizations to math functions.
233 Implemented by Ulrich Drepper.
235 * New configure option --enable-obsolete-rpc makes the deprecated RPC
236 headers and functions available at compile time as they were before
237 version 2.14. This option will be removed at some time in the future
238 after the TI-RPC library becomes fully sufficient for the needs of
239 existing applications.
241 * Compatibility code for Linux kernel versions before 2.4 has been removed.
242 Note that glibc is not expected to work with any Linux kernel version
243 before 2.6.
245 * New header <sys/auxv.h> and function getauxval allowing easy access to
246 the AT_* key-value pairs passed from the Linux kernel. The header also
247 defines the HWCAP_* bits associated with the AT_HWCAP key.
249 * New locales: mag_IN
251 * New configure option --enable-systemtap builds SystemTap static probes
252 into libc for setjmp and longjmp and into libpthread for various operations.
253 So far the setjmp/longjmp probes and some of the libpthread probes are
254 provided only for i*86 and x86_64.
255 Implemented by Roland McGrath and Rayson Ho.
257 * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
259 * More optimized functions for PowerPC. Implemented by Adhemerval Zanella
260 and Will Schmidt.
262 * More optimized functions for SPARC. Implemented by David S. Miller.
264 * Improved support for cross-compilation, especially bootstrap builds
265 without a previously built glibc.
267 * Ports for the TILE-Gx and TILEPro families of processors. Contributed by
268 Chris Metcalf from Tilera.
270 * Support for the old ARM ABI has been removed from ports. Only the EABI is
271 now supported for ARM processors.
273 * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
274 as the name of the dynamic linker, to distinguish it from the
275 /lib/ld-linux.so.3 dynamic linker used for the base EABI.
277 * Support for CRIS has been removed from ports.
279 * A new class of installed header has been documented for low-level
280 platform-specific functionality. PowerPC added the first instance with a
281 function to provide time base register access. Contributed by Tulio
282 Magno Quites Machado Filho.
284 * ix86 configurations now install header files that are consistent with
285 what x86-64 configurations install. These same header files can be used
286 for -m32, -m64, or -mx32 builds.
287 Contributed by H.J. Lu.
289 * Math library bug fixes. A thorough audit of all open math library bugs was
290 conducted by Joseph Myers. Significant progress was made on many math
291 library bugs resulting in more accurate exceptions and function results.
292 Many thanks to all those that contributed including Andreas Jaeger for his
293 patch review and work on the x87 trigonometric instruction issues.
295 * Timezone data is no longer installed. Timezone-related binaries and scripts
296 will continue to be installed. Users should obtain their timezone data from
297 their distribution provider or from the tzdata package at
298 <ftp://munnari.oz.au/pub/>.
299 \f

310 13484, 13506, 13515, 13523, 13524, 13538, 13540
312 * New program pldd to list loaded object of a process
313 Implemented by Ulrich Drepper.
315 * Add nss_db support back to glibc. No more dependency on Berkeley db
316 and support for initgroups lookups.
317 Implemented by Ulrich Drepper.
319 * Optimized strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-32.
320 Contributed by HJ Lu.

326 on x86-32 and x86-64.
327 Contributed by Liubov Dmitrieva.
329 * Optimized strchr and strrchr for SSE on x86-32.
330 Contributed by Liubov Dmitrieva.
332 * Optimized memchr, memrchr, rawmemchr, memcmp, wmemcmp, wcschr, wcscpy
333 for x86-64 and x86-32.
334 Contributed by Liubov Dmitrieva.
336 * New interfaces: scandirat, scandirat64
337 Implemented by Ulrich Drepper.
339 * Checking versions of FD_SET, FD_CLR, and FD_ISSET added.
340 Implemented by Ulrich Drepper.
342 * nscd now also caches the netgroup database.
343 Implemented by Ulrich Drepper.
345 * Integrate libm with gcc's -ffinite-math-only option.
346 Implemented by Ulrich Drepper.

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

442 * The dynamic linker now recognizes supported ABI versions from the
443 EI_ABIVERSION field in the ELF header.
444 Implemented by Ulrich Drepper.
446 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
447 will not be used to fill in password fields in the passwd.byname replies.
448 Instead it is used to synthesize the shadow.byname table, should it be
449 missing. This is a useful mode in some installations involving Solaris.
450 Implemented by Ulrich Drepper.
452 * New locales: kok_IN, sq_MK, cv_RU
453 \f
454 Version 2.11

479 strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2).
480 Contributed by H.J. Lu.
482 strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3).

495 * STB_GNU_UNIQUE support added.
496 Implemented by Ulrich Drepper.
498 * Implement second fallback mode for optimized DNS lookup for even more
499 broken environments. If two requests from the same port are not
500 handled correctly close the socket and open a new one before sending
501 the second request. The 'single-request-reopen' option in /etc/resolv.conf
502 can be used to select this mode right away, instead of rediscovering the
503 necessity is every process again.
504 Implemented by Ulrich Drepper.
506 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
507 Implemented by Adam Tkac.
509 * Optimized iconv conversions for S390x.
510 Implemented by Andreas Krebbel.

514 Implemented by Ulrich Drepper.
516 * New locales: ps_AF, my_MM
517 \f

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

603 * Implement "e" option for popen to open file descriptor with the
604 close-on-exec flag set. Implemented by Ulrich Drepper.
606 * Implement "b" mode for fmemopen. In this mode writes writes don't
607 implicitly add a NUL byte and seeks from the end of the buffer really
608 use the buffer end, not the string length as the basis.
609 Implemented by Ulrich Drepper.
611 * Many functions, exported and internal, now atomically set the close-on-exec
612 flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
614 * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
615 Sinhala)
616 Implemented by Pravin Satpute.

722 4702, 4858
724 * New Linux interfaces: epoll_pwait, sched_getcpu.
726 * New generic interfaces: strerror_l.
728 * nscd can now cache the services database. Implemented by Ulrich Drepper.
729 \f
730 Version 2.5
732 * The following bugs are resolved with this release:
734 39, 68, 192, 352, 388, 531, 935, 1006, 1201, 1203, 1386, 1782, 1783, 1784,
735 1785, 1786, 1787, 1951, 1974, 1996, 2072, 2098, 2125, 2134, 2158, 2182,
736 2349, 2376, 2386, 2389, 2415, 2418, 2420, 2423, 2450, 2451, 2466, 2472,
737 2473, 2477, 2498, 2499, 2501, 2502, 2505, 2507, 2508, 2509, 2517, 2526,
738 2569, 2571, 2592, 2611, 2625, 2632, 2644, 2662, 2680, 2683, 2684, 2693,
739 2695, 2703, 2734, 2751, 2764, 2766, 2775, 2792, 2821, 2823, 2832, 2841,
740 2843, 2883, 2892, 2908, 2914, 2926, 2961, 2978, 2980, 2987, 2997, 2998,
741 3013, 3018, 3034, 3040, 3044, 3123, 3124, 3137, 3138, 3143, 3155, 3189,
742 3225, 3251, 3252, 3253, 3273
744 * For Linux, the sorting of addresses returned by getaddrinfo now also
745 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
746 Implemented by Ulrich Drepper.
748 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
749 Implemented by Ulrich Drepper.
751 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
753 * New iconv module for MIK. Contributed by Alexander Shopov.
755 * For sites with broken group and/or passwd database, the auto-propagate
756 option of nscd can prevent creating ID lookup entries from the results
757 of a name lookup and vice versa. This usually is no problem but some
758 site might have problems with the default behavior.
759 Implemented by Ulrich Drepper.
761 * Iterating over entire database in NIS can be slow. With the
762 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
763 to trade time for memory. The entire database will be read at once.
764 Implemented by Ulrich Drepper.
766 * The interfaces introduced in RFC 3542 have been implemented by
767 Ulrich Drepper.
769 * Support for the new ELF hash table format was added by Ulrich Drepper.
771 * Support for priority inheritance mutexes added by Jakub Jelinek and
772 Ulrich Drepper.
774 * Support for priority protected mutexes added by Jakub Jelinek.
776 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
777 or_IN, csb_PL, fy_NL, sr_ME.
778 \f
779 Version 2.4
781 * More overflow detection functions.
783 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
784 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
786 More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,
787 IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144,
788 IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517,
789 IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
790 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
791 by Masahide Washizawa.
793 * It is now possible to install audit libraries for the dynamic linker using
794 LD_AUDIT. Implemented by Ulrich Drepper.
796 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
797 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
798 For a libc and libpthread that works well on Linux 2.4 kernels, we
799 recommend using the stable 2.3 branch.
801 * The new function open_wmemstream acts like open_memstream,
802 but uses a wchar_t wide character buffer.
804 * The new function ppoll is an improved version of poll, similar to pselect.
806 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
807 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
808 renameat, unlinkat, linkat, symlinkat, readlinkat.
810 * New Linux kernel system calls: unshare,
811 inotify_init, inotify_add_watch, inotify_rm_watch.
813 * The euidaccess function is now also known by the alias eaccess,
814 for compatibility with some other systems.
816 * Timezone data updated to 2006b version.
817 \f
818 Version 2.3.6
820 * The following bugs are resolved with this release:
822 38, 253, 549, 622, 653, 721, 758, 851, 877, 915, 934, 955, 961,

829 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
831 * As of this release, GCC 4 can be used to compile the C Library.
833 * Timezone data updated to 2005m version.
834 \f
835 Version 2.3.5
837 * The following bugs are resolved with this release:
839 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

844 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
845 \f
846 Version 2.3.4
848 * Support for RFC 3678. Real implementations exist only for Linux so far.
849 Implemented by Ulrich Drepper.
851 * nscd can now cache entries persistently. Expiring entries are reloaded.
852 For speedups the cache can be shared in memory with client processes.
853 Implemented by Ulrich Drepper.
855 * nscd can now perform SELinux checks.
856 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
858 * getaddrinfo queries are now cached. Canonical name lookup is performed
859 efficiently.
860 Implemented by Ulrich Drepper.
862 * The nothrow function attribute is used when headers are used by gcc when
863 compiling C code. This can avoid significant amounts of exception
864 handling data.
866 * The malloc functions perform more error checking and are stricter when
867 it comes to reacting on errors. The default action is to terminate
868 the process after showing an error message. Implemented by Ulrich Drepper.
870 * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
871 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
873 * Namespaces in ld.so are implemented. DSOs can be loaded in separate
874 namespaces using the new function dlmopen(). This feature is of course,
875 like most other dynamic loading functionality, not available in statically
876 linked applications. Implemented by Ulrich Drepper.
878 * Low-overhead boundary checking variants of string and some stdio functions
879 were added. These are to be used in conjunction with a gcc patch by
880 Jakub Jelinek which adds calls to these functions if possible.
881 Implemented by Jakub Jelinek and Ulrich Drepper.
883 * Old code for several operating systems and machine architectures that
884 have not been in working condition in a long time have been removed from
885 the main source tree maintained by the GNU C Library's maintainers.
886 These files are now reside in the separate `ports' source module
887 that is usable as an add-on when building the library.
888 \f
889 Version 2.3.3
891 * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
892 interrogate the dynamic linker, compatible with the Solaris interface.
894 * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
895 implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
897 * getifaddrs now uses the netlink interface on Linux to get its information.
898 Implemented by Thorsten Kukuk.
900 * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
901 Implemented by Ulrich Drepper.
903 * support for non-executable stacks on x86 has been added. Changes mostly
904 by Roland McGrath.
906 * regex is now much faster for multibyte locales. Changes by Jakub Jelinek
907 and Ulrich Drepper.
909 * getaddrinfo now performs destination address selection according to
910 RFC 3484.
911 \f
912 Version 2.3.2
914 * Thread-safe interfaces for many functions that access locale data
915 were added in version 2.3, but these features were omitted from NEWS.
916 Many functions have variants with an `_l' suffix that take a `locale_t'
917 object as a parameter rather than consulting the current locale.
918 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
919 create and maintain `locale_t' objects. Additionally, the new function
920 `uselocale' sets "the current locale" (as used by functions not so
921 parameterized) set for an individual thread. These features were added
922 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
924 * The functions getresuid, getresgid, setresuid, and setresgid, which
925 have long been available on Linux, are now declared in <unistd.h>
926 and are now also available on the Hurd.
928 * ELF thread-local storage support (TLS) now works on x86-64.
930 * The new dynamic string token $LIB is expanded in shared library names.
931 This normally expands to lib, but on some 64-bit platforms to lib64 instead.
933 * Aldy Hernandez contributed complete software floating point support for
934 PowerPC machines with no FPU.
936 * fexecve is implemented on Linux.
938 * The `btowc' function should work at least twice as fast due to
939 specialized callbacks in the iconv modules. Implemented by Bruno Haible.
941 * With approriate thread add-ons cancelable functions are now implemented
942 in libc.so as well. No need to call the function in libpthread. This
943 change allowed to finally disable the incorrect and expensive handling
944 of weak definition in ld.so.
946 * Yet more PLT entries in libc.so have been removed. We finally arrived
947 at the bare minimum. Startup times improved appropriately.
949 * Support for the new Linux/x86 system call interface was added. The
950 AT_SYSINFO auxiliary vector entry is recognized and handled.
951 \f
952 Version 2.3
954 * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
955 charsets.
957 * iconv (the program and the interface) now accepts empty names (excluding
958 options like //TRANSLIT) to mean "use charset of current locale".
960 * localedef can now transliterate characters in strings which are not in
961 the provided charmap. The information from the input locale is used.
963 * Prelinking support was added for ELF targets. This requires additional
964 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
966 * Read-only stdio streams now use mmap to speed up operation by eliminating
967 copying and buffer underflows. To use add 'm' to the mode string of
968 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
970 * The malloc functions were completely rewritten by Wolfram Gloger based
971 on Doug Lea's malloc-2.7.0.c.
973 * Isamu Hasegawa contributed a completely new and POSIX-conformant
974 implementation of regex.
976 * Bruno Haible upgraded the iconv and locale implementation to support
977 Unicode 3.2.
979 * Contents of the LC_* and LANG environment variables in the CEN style are
980 not recognized anymore. It never was used. Change by Ulrich Drepper.
982 * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
983 thread-local storage (TLS) ABI on some platforms.
984 Changes by Ulrich Drepper. SH support by Kaz Kojima.
986 * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
987 EUC-JISX0213, and TSCII.
989 * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
990 BSD-compatible interface for getting all network interface addresses.
991 Implementation for IPv4 by Roland McGrath.
993 * Loading of locale data is faster due to the introduction of a locale
994 archive. Implemented by Roland McGrath and Ulrich Drepper.
996 * Startup times are significantly reduced by not using exported functions
997 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
998 and Ulrich Drepper.
1000 * Steven Munroe contributed a port to PowerPC64/Linux.
1001 \f
1002 Version 2.2.6
1004 * The Hurd now uses the GNU libio implementation of stdio rather than the
1005 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
1007 * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
1008 with the same behavior as the Linux system call of the same name.
1009 \f
1010 Version 2.2.5
1012 * Stephen Moshier implemented log2, log10, powl and cbrtl for the
1013 128-bit long double format.
1015 * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
1016 IBM1161, and IBM1162 charsets.
1018 * Andreas Jaeger contributed a port to x86-64/Linux.
1020 * Peter Bruin contributed a port to PowerPC/Hurd.
1022 * libc functions using I/O streams now can handle wide-oriented streams
1023 as well.
1025 * optimizations in the dynamic linker. Binaries created by recent binutils
1026 versions start up quicker due to reduced time spent on relocations.
1028 * Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
1029 \f
1030 Version 2.2.4
1032 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
1033 asinh, atanh, j0 for the 128-bit long double format.
1035 * Bruno Haible updated all the code handling Unicode in some form to
1036 support Unicode 3.1.
1038 * Speed of regex for single-byte locales is back to previous levels.
1039 Patch by Isamu Hasegawa.
1041 * Alpha, SPARC, and IA-64 now also using floating stacks.
1043 * Startup time of internationalized applications greatly improved through
1044 iconv cache. Use iconvconfig to generate the cache file.
1045 Contributed by Ulrich Drepper.
1047 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
1048 severe performance problems. Patch by David Mosberger.
1050 * The Hurd port got a lot more functionality like AIO, various stdio
1051 extensions, etc. Mainly done by Roland McGrath.
1053 * mtrace can now lookup symbols in shared libraries.
1054 \f
1055 Version 2.2.3
1057 * Intel's IA-64 math library is largely integrated. It provides fast and
1058 accurate implementatations for most basic and standard math functions
1059 in float, double, and long double format.
1061 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
1062 and asin for the 96-bit long double format and asin, log, tan for the
1063 128-bit long double format.
1065 * The beginning of a last-bit accurate math library by IBM Haifa were added.
1066 The basic double functions exist today. Contributed by Abraham Ziv
1067 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
1068 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
1070 * An asynchronous name lookup library was added. The interface is designed
1071 after POSIX AIO. The proposal was circulated beforehand to get comments.
1072 No negative ones came in. Implemented by Ulrich Drepper.
1074 * Port to S390/64bit contributed by Martin Schwidefsky
1075 <schwidefsky@de.ibm.com>.
1077 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
1078 of functions for Linux/IA-64.
1080 * The RPC code is now thread safe. Threads can now use the same service
1081 of different services at the same time. Patch by Eric Norum
1082 <eric.norum@usask.ca> with some help by Ulrich Drepper.
1084 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
1085 family of functions for Linux/S390.
1087 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
1088 of functions for Linux/x86.
1090 * Port to Linux/CRIS contributed by Axis Communications.
1091 \f
1092 Version 2.2.2
1094 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
1095 we can now check for namespace violations and missing declarations. The
1096 result is that almost all headers are now Unix-compliant (as defined in
1097 the upcoming XPG6). The negative side is that some programs might need
1098 corrections, too, if they depend on the incorrect form of the headers in
1099 previous versions which defined too many symbols and included too many
1100 other headers.
1102 * regex now handles multibyte character sets correctly.
1103 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
1105 * iconv (the program) does now conform to the upcoming XPG6 and handles
1106 charmaps. Instead of the charset names the path of charmaps can be
1107 provided and the conversion happens based on this data.
1108 Contributed by Ulrich Drepper.
1110 * The locale program now provides detailed information about the installed
1111 locales. While
1113 locale -a
1115 only lists the names of the supported locales
1117 locale -a --verbose
1119 provides details such as country, language, and codeset name.
1120 Contributed by Ulrich Drepper.
1121 \f
1122 Version 2.2.1
1124 * The gencat program now parses the input file according to the charset
1125 selected by the LC_CTYPE category. This is important for stateful
1126 character sets. To make generating catalogs easier there is a way
1127 to overwrite the charset selected by the locale: before the first
1128 message or $ quote line the catalog can contain a line like
1130 $ codeset=ISO-8859-2
1132 to select the charset (ISO-8859-2 in this case).
1134 Implemented by Shinya Hanataka and Ulrich Drepper.
1136 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
1137 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
1138 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
1140 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
1141 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
1143 * The LANGUAGE environment variable is now ignored unless the locale is
1144 changed from the default "C" locale.
1146 * The usual bug fixes.
1147 \f
1148 Version 2.2
1150 * Greg McGary added runtime support for bounds checking using gcc's
1151 new -fbounded-pointers option. ix86 target is complete. PowerPC
1152 is in progress.
1154 * Thorsten Kukuk added secure mode support to nscd.
1156 * The Berkeley db libraries have been removed.
1158 Related, the nss_db module is now in a separate package since it
1159 obviously requires a database library being available.
1161 * Wide character I/O streams implemented by Ulrich Drepper.
1163 * Functions from the extended socket API added by Ulrich Drepper.
1165 * Functions feenableexcept and fedisableexcept to control the
1166 behaviour of individual exceptions have been added by Andreas Jaeger.
1168 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
1170 * The resolver code has been updated from bind 8.2.3-T5B which supports
1171 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
1172 and Mark Kettenis.
1174 This change could in some situations effect backward compatibility. Since
1175 now `_res' is a thread-local instead of a global variable, modifying it
1176 in one thread does not have any effect in other threads.
1178 The resolver library was also extended to allow IPv6 as the transport
1179 protocol for the requests. This work was done by Stig Venaas.
1181 * Compatibility code for K&R C compilers has been removed from the
1182 header files. A ISO C compiler is needed to use the library
1183 (conforming to either C89 or C99 standard).
1185 * Complete rewrite of the localedef program to support multibyte character
1186 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
1187 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
1188 Implemented by Ulrich Drepper.
1190 Bruno Haible significantly improved the generation and use of the data
1191 structures for the wide character tables.
1193 * Plural handling in gettext implemented by Ulrich Drepper.
1195 * The utmp daemon has been removed.
1197 * The port to MIPS-Linux has been finished by Andreas Jaeger.
1199 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
1200 and Yutaka Niibe.
1202 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
1204 * POSIX barriers implemented by Kaz Kylheku.
1206 * POSIX spawn function family implemented by Ulrich Drepper.
1208 * POSIX spinlocks are now available.
1210 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
1212 * the configure option --enable-kernel=X.Y.Z allows to strip out
1213 compatibility for kernel versions before X.Y.Z. This is currently only
1214 implemented for Linux.
1216 * the sockaddr_in6 structure changed. The IPv6 working group added a new
1217 field sin6_scope_id. This means that all programs using IPv6 should be
1218 recompiled. Don't expect binary compatibility with previous glibc
1219 versions.
1221 * various conversion modules for IBM character sets contributed by
1222 Masahide Washizawa.
1224 * IA-64 port by Jes Sorensen and HJ Lu.
1225 \f
1226 Version 2.1.3
1228 * bug fixes
1230 \f
1231 Version 2.1.2
1233 * bug fixes
1235 \f
1236 Version 2.1.1
1238 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
1240 * New xdr functions are added; some rpc functions are now 64bit clean.
1242 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
1244 * Fixed known incompatibilities with glibc 2.0.
1246 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
1248 * Optimized a number of functions (especially the ELF dynamic loader).
1250 * Update timezone data files.
1252 * lots of charmaps corrections
1254 * some new locale definitions and charmaps
1256 \f
1257 Version 2.1
1259 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
1260 conform to POSIX member type requirements. Symbol versions have been
1261 adjusted as needed within the library, and for direct use by applications,
1262 but there is potential for problems if third-party libraries use
1263 struct timeval as part of their interface. This does not present
1264 a problem for X and other "essential" system libraries.
1266 * An additional locale model to support C++ Standard Library locale
1267 model and probably more was implemented by Ulrich Drepper.
1269 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
1270 symbol level.
1272 * Miles Bader provided the `argp' function family to support hierachical
1273 command line argument parsing, layered on top of getopt.
1275 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
1277 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
1278 numbers.
1280 * scanf recognizes the %a and %A format for scanning floating point numbers.
1282 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
1283 information and interfaces for the available integer types.
1285 * about 130 new math functions were added to implement the ISO C9x math
1286 library.
1288 * the new header <complex.h> contains definitions of the complex math
1289 functions from ISO C 9X.
1291 * the new header <tgmath.h> defines generic macros to use complex or
1292 real valued functions.
1294 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
1296 * Andreas Jaeger provided a test suite for the math library.
1298 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
1300 * Ulrich Drepper added character set conversion functions (iconv).
1302 * Optimized string functions have been added.
1304 * The localedata addon is now part of glibc.
1306 * An implementation of profiling shared libraries was added by Ulrich Drepper.
1308 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
1309 daemon for NSS (nscd).
1311 Missing a better place here are some numbers on improvements. Under
1312 Linux 2.1.125 un-tar-ing the kernel sources takes
1314 user system wall
1316 using local files 12.19s 6.88s 22.91s
1318 using NIS 13.92s 8.91s 26.34s
1320 using NIS & nscd 10.37s 7.34s 25.30s
1322 using NIS+ 27.57s 30.37s 640.46s
1324 using NIS+ & nscd 10.25s 7.83s 26.51s
1326 using NIS & old nscd [1] 13.83s 8.32s 29.60s
1328 Keep in mind that non-namelookup related operations dominate above times.
1329 It was just a common complain that using NIS+ unpacking the kernel is
1330 horribly slow.
1332 [1] The old nscd implementation is not available anymore since it was
1333 distributed with glibc up to version 2.0.98 and thus is now replaced.
1335 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
1337 * Mark Kettenis provided a Hesiod NSS module.
1339 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
1340 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
1342 * rcmd can now handle netgroups (Dick Streefland).
1344 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
1345 Bambrough.
1347 * Support for the IPv6 protocol has been added to the socket API, as per the
1348 latest draft standards.
1350 * Support for Linux 2.2 has been added.
1352 * Interface changes relative to the latest 2.0.x release:

1721 Version 2.0.1
1723 * fixed lots of header problems (especially Linux/GNU specific)
1725 * dynamic loader preserves all registers
1727 * Roland McGrath provided support for handling of auxiliary objects in
1728 the ELF dynamic loader.
1730 * support for parallel builds is improved
1731 \f
1732 Version 2.0
1734 * GNU extensions are no longer declared by default. To enable them you
1735 must define the macro `_GNU_SOURCE' in your program or compile with
1736 `-D_GNU_SOURCE'.
1738 * The library has changed from using GNU ld symbol aliases to using weak
1739 symbols where available. The ELF object file format supports weak
1740 symbols; GNU ld also supports weak symbols in the a.out format. (There
1741 is also now support for other GNU ld extensions in ELF. Use the
1742 `--with-elf' option to configure to indicate you have ELF, and
1743 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
1744 of many files which contained only symbol aliases, reducing the size of
1745 the source and the compiled library; many other files were renamed to
1746 less cryptic names previously occupied by the symbol alias files.
1747 There is a new header file <elf.h> for programs which operate on
1748 files in the ELF format.
1750 * Converted to Autoconf version 2, so `configure' has more options.
1751 Run `configure --help' to see the details.
1753 * The library can now be configured to build profiling, highly-optimized
1754 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1755 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1756 `configure' enable building these extra libraries. The shared library is
1757 built by default when using both ELF and GNU ld. When shared libraries
1758 are enabled, the new library `-ldl' is available for arbitrary run-time
1759 loading of shared objects; its interface is defined in <dlfcn.h>. The
1760 new header file <link.h> gives access to the internals of the run-time
1761 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1762 application of same name on other systems and it provides information
1763 about dynamically linked binaries.
1765 * The C library now provides the run-time support code for profiling
1766 executables compiled with `-pg'. Programs can control the profiling code
1767 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1768 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1769 the support for this file format was contributed by David Mosberger-Tang.
1771 * The math code has been replaced with a math library based on fdlibm from
1772 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1773 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1774 functions. The math functions now reside in a separate library, so
1775 programs using them will need to use `-lm' their linking commands.
1777 * John C. Bowman contributed optimized ix87 assembler inline functions.
1779 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1780 mechanism similar to that found in Solaris 2. This is now used for the
1781 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1782 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1783 file controls what services are used for each individual database. This
1784 works by loading shared libraries with names specified in `nsswitch.conf',
1785 so service modules can be changed or added at any time without even
1786 relinking any program. Currently there are the file, db, and NIS based
1787 NSS services available.
1789 * The new functions `strtoq' and `strtouq' parse integer values from
1790 strings, like `strtol' and `strtoul', but they return `long long int' and
1791 `unsigned long long int' values, respectively (64-bit quantities).
1793 * The new functions `strtof' and `strtold' parse floating-point values from
1794 strings, like `strtod', but they return `float' and `long double' values,
1795 respectively (on some machines `double' and `long double' are the same).
1797 * Ulrich Drepper has contributed new implementations of the floating-point
1798 printing and reading code used in the `printf' family of functions and
1799 `strtod', `strtof', and `strtold'. These new functions are perfectly
1800 accurate, and much faster than the old ones.
1802 * The implementation of the POSIX locale model was completely rewritten by
1803 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1804 to compile the POSIX locale definition.
1806 * The former dummy implementations of the strcoll and strxfrm function are
1807 now replaced by fully functional code contributed by Ulrich Drepper. The
1808 collation information comes from the POSIX locale definitions.
1810 * The new header <langinfo.h> defines an interface for accessing
1811 various locale-dependent data (using the locale chosen with `setlocale').
1813 * Ulrich Drepper has contributed a new suite of functions for operation on
1814 wide-character and multibyte-character strings, in <wchar.h>;
1815 and classification and case conversion of wide characters, in <wctype.h>.
1816 These new functions are conforming to the ISO C, Amendement 1 specification.
1818 * There is now a second implementation of the standard I/O library available.
1819 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1820 by Hongjiu Lu and made thread safe by Ulrich Drepper.
1822 * You can now use positional parameter specifications in format strings
1823 for the `printf' and `scanf' families of functions. For example,
1824 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1825 ``Number 6, Mr Jones''. This is mainly useful when providing different
1826 format strings for different languages, whose grammars may dictate
1827 different orderings of the values being printed. To support this
1828 feature, the interface for `register_printf_handler' has changed; see
1829 the header file <printf.h> for details.
1831 * The `printf' and `scanf' families of functions now understand a new
1832 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1833 to group numbers as indicated by the locale; for `scanf' and friends, this
1834 says to accept as valid only a number with all the proper grouping
1835 separators in the right places. In the default "C" locale, numbers are
1836 not grouped; but locales for specific countries will define the usual
1837 conventions (i.e. separate thousands with `,' in the US locale).
1839 * The pgrp functions have been regularized, slightly incompatibly but much
1840 less confusingly. The core functions are now `getpgid' and `setpgid',
1841 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1842 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1843 provided for compatibility. There is no longer an incompatible `getpgrp'
1844 with an argument declared under _BSD_SOURCE; no BSD code uses it.
1846 * The new header file <fts.h> and suite of functions simplify programs that
1847 operate on directory trees. This code comes from 4.4 BSD.
1849 * The resolver code has been updated from the BIND 4.9.5-P1 release.
1850 Parts of the code were heavily modified by Ulrich Drepper to fit in the
1851 NSS scheme used in glibc.
1853 * There is a new malloc debugging hook `__memalign_hook'.
1855 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
1856 `unsigned int' in <sys/types.h>. These are for compatibility only and
1857 their use is discouraged.
1859 * The `-lmcheck' library to enable standard malloc debugging hooks is now
1860 done differently, so that it works even without GNU ld.
1862 * New function `euidaccess' checks allowed access to a file like `access',
1863 but using the effective IDs instead of the real IDs.
1865 * The time zone data files have been updated for the latest and greatest
1866 local time conventions of the countries of the world.
1868 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
1869 see <dirent.h>.
1871 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
1872 for formatting floating-point numbers. They are provided only for
1873 compatibility; new programs should use `sprintf' instead. There are
1874 also equivalent function for the `long double' floating-point type and
1875 all functions also exist in a reentrant form.
1877 * The new auxiliary library `-lutil' from 4.4 BSD contains various
1878 functions for maintaining the login-record files (primarily of use to
1879 system programs such as `login'), and convenient functions for
1880 allocating and initializing a pseudo-terminal (pty) device.
1882 * Ulrich Drepper has contributed new support for System V style
1883 shared memory and IPC on systems that support it.
1885 * Ulrich Drepper has contributed several miscellaneous new functions found
1886 in System V: The `hsearch' family of functions provide an effective
1887 implementation of hash tables; `a64l' and `l64a' provide a very simple
1888 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
1889 number generator.
1891 * Ulrich Drepper has contributed new reentrant counterparts for the
1892 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
1894 * Ulrich Drepper has contributed new, highly-optimized versions of several
1895 string functions for the i486/Pentium family of processors.
1897 * Ulrich Drepper has updated the Linux-specific code, based largely
1898 on work done in Hongjiu Lu's version of GNU libc for Linux.
1899 The GNU library now supports Linux versions 2.0.10 and later,
1900 using the ELF object file format (i[3456]86-*-linux).
1902 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
1904 * David Mosberger-Tang and Richard Henderson have ported the C library
1905 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
1906 dynamic linking support for ELF/Alpha.
1908 * Richard Henderson contributed several Alpha optimized assembler function
1909 for arithmetic and string handling.
1911 * Ulrich Drepper has contributed a new set of message catalog functions to
1912 support multiple languages using the <libintl.h> interface, for use with
1913 his new package GNU gettext. Translation volunteers have contributed
1914 catalogs of the library's messages in Spanish, German, and Korean.
1916 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
1917 program and the `catgets' function for reading the catalog files it
1918 creates. (The <libintl.h> interface is preferred; we include the
1919 <nl_types.h> interface using `catgets' only for source compatibility with
1920 programs already written to use it.)
1922 * New header file <values.h> gives SVID-compatible names for <limits.h>
1923 constants.
1925 * Various new macros, declarations, and small header files for compatibility
1926 with 4.4 BSD.
1928 * New function `group_member' is a convenient way to check if a process has
1929 a given effective group ID.
1931 * When using GCC 2.7 and later, the socket functions are now declared in a
1932 special way so that passing an argument of type `struct sockaddr_in *',
1933 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
1934 `struct sockaddr *' type, does not generate a type-clash warning.
1936 * New function `error' declared in header file <error.h> is a convenient
1937 function for printing error messages and optionally exiting; this is the
1938 canonical function used in GNU programs. The new functions `err', `warn',
1939 and friends in header file <err.h> are the canonical 4.4 BSD interface for
1940 doing the same thing.
1942 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
1943 POSIX.2 `glob' function to do ~ and {...} expansion.
1945 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
1946 `clearenv' which is used in POSIX.9 is also available.
1948 * New function `getsid' returns session ID number on systems that support it.
1950 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1951 files <db.h> and <mpool.h> provide a rich set of functions for several
1952 types of simple databases stored in memory and in files, and <ndbm.h> is
1953 an old `ndbm'-compatible interface using the `db' functions. Link with
1954 `-ldb' to get these functions.
1956 * New macro `strdupa' copies a string like `strdup', but uses local stack
1957 space from `alloca' instead of dynamic heap space from `malloc'.
1959 * New function `strnlen' is like `strlen' but searches only a given maximum
1960 number of characters for the null terminator. `stpncpy', `strndup' and
1961 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1962 function.
1964 * New function `statfs' in header <sys/statfs.h>.
1966 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1967 provide convenient functions for operating on blocks of null-terminated
1968 strings.
1970 * A new suite of functions in <utmp.h> handle all the details of reading
1971 and writing the utmp file.
1973 * An implementation of the NIS/YP(tm) based NSS service was contributed by
1974 Thorsten Kukuk.
1976 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1977 completely POSIX compliant and also implemented the extended functionality
1978 to handle alternate digit representation and alternate era date formats.
1980 * Ulrich Drepper provided an implementation of the `strptime' function
1981 defined in XPG4.2 which transforms a string into a `struct tm' value.
1983 * Paul Eggert provided the tzselect shell script as part of the timezone
1984 code. The shell script makes it easy to select the correct timezone
1985 specification.
1987 * The implementation of the malloc family of functions is completely replaced
1988 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1989 The implementation uses the mmap function (if available) and it is
1990 optimized for the use in multi threaded programs.
1992 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1993 functions. This new functionality is usable by specifying a special
1994 salt string and it is compatible with implementation on *BSD systems.
1996 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1997 `getsubopt' to handle second level command line options, `bsd_signal'
1998 to access BSD style `signal' functionality, the obsolete `regexp' style
1999 expression matcher.
2001 * the `lchown' function is available on system which support this
2002 functionality.
2004 * The implementation of the shadow password handling function was contributed
2005 by Ulrich Drepper.
2007 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
2009 * POSIX.1g support was added. The <sys/select.h> header is available,
2010 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
2011 implementation of `getaddrinfo'.
2012 \f
2013 Version 1.09
2015 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
2017 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
2018 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
2020 * The new function `daemon' from 4.4 BSD is useful for server programs that
2021 want to put themselves in the background.
2023 * Joel Sherrill has contributed support for several standalone boards that
2024 run without an operating system.
2026 * `printf', `scanf' and friends now accept a `q' type modifier for long
2027 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
2029 * All of the code taken from BSD (notably most of the math and networking
2030 routines) has been updated from the BSD 4.4-Lite release.
2032 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
2034 * The new functions `getdomainname' and `setdomainname' fetch or change the
2035 YP/NIS domain name. These are system calls which exist on systems which
2036 have YP (aka NIS).
2038 * The time zone data files have been updated for the latest international
2039 conventions.
2041 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
2042 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
2043 \f
2044 Version 1.08
2046 * The C library now includes support for Sun RPC, from Sun's free
2047 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
2048 are included. (There is still no support for YP.)
2050 * Tom Quinn has contributed a port of the C library to SGI machines running
2051 Irix 4 (mips-sgi-irix4).
2053 * The new `lockf' function is a simplified interface to the locking
2054 facilities of `fcntl', included for compatibility.
2056 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
2058 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
2060 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
2061 compatibility.
2063 * The error message printed by `assert' for a failed assertion now includes
2064 the name of the program (if using GNU ld) and the name of the calling
2065 function (with versions of GCC that support this).
2067 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
2069 * The library now includes the <sys/mman.h> header file and memory
2070 management functions `mmap', `munmap', `mprotect', `msync', and
2071 `madvise', on systems that support those facilities.
2073 * The interface for `mcheck' has changed slightly: the function called to
2074 abort the program when an allocation inconsistency is detected now takes
2075 an argument that indicates the type of failure. The new function
2076 `mprobe' lets you request a consistency check for a particular block at
2077 any time (checks are normally done only when you call `free' or `realloc'
2078 on a block).
2080 * It is now possible to easily cross-compile the C library, building on one
2081 system a library to run on another machine and/or operating system. All
2082 you need to do is set the variable `HOST_CC' in `configparms' to the
2083 native compiler for programs to run on the machine you are building on (a
2084 few generator programs are used on Unix systems); set `CC' to the
2085 cross-compiler.
2087 * The new function `fexecve' (only implemented on the GNU system) executes
2088 a program file given a file descriptor already open on the file.
2089 \f
2090 Version 1.07
2092 * Brendan Kehoe has contributed most of a port to the DEC Alpha
2093 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
2095 * You can set the variable `libprefix' in `configparms' to specify a prefix
2096 to be prepended to installed library files; this makes it easy to install
2097 the GNU C library to be linked as `-lgnuc' or whatever.
2099 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
2100 copies a limited number of characters from a string, and returns the
2101 address of the last character written.
2103 * You no longer need to check for whether the installed `stddef.h' is
2104 compatible with the GNU C library. configure now checks for you.
2106 * You can now define a per-stream `fileno' function to convert the
2107 stream's cookie into an integral file descriptor.
2109 * ``malloc (0)'' no longer returns a null pointer. Instead, it
2110 allocates zero bytes of storage, and returns a unique pointer which
2111 you can pass to `realloc' or `free'. The behavior is undefined if
2112 you dereference this pointer.
2114 * The C library now runs on Sony NEWS m68k machines running either
2115 NewsOS 3 or NewsOS 4.
2117 * The new `syscall' function is a system-dependent primitive function
2118 for invoking system calls. It has the canonical behavior on Unix
2119 systems, including unreliable return values for some calls (such as
2120 `pipe', `fork' and `getppid').
2122 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
2123 to `EAGAIN', which is the preferred name. On systems whose kernels
2124 use two distinct codes, the C library now translates EWOULDBLOCK to
2125 EAGAIN in every system call function.
2126 \f
2127 Version 1.06
2129 * The GNU C Library Reference Manual is now distributed with the library.
2130 `make dvi' will produce a DVI file of the printed manual.
2131 `make info' will produce Info files that you can read on line using C-h i
2132 in Emacs or the `info' program.
2133 Please send comments on the manual to bug-glibc-manual@gnu.org.
2135 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
2137 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
2139 * Jason Merrill has contributed a port to the Sequent Symmetry running
2140 Dynix version 3 (i386-sequent-dynix).
2142 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
2143 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
2145 * New function `memory_warnings' lets you arrange to get warnings when
2146 malloc is running out of memory to allocate, like Emacs gives you.
2148 * The C library now contains the relocating allocator used in Emacs 19 for
2149 its editing buffers. This allocator (ralloc) minimizes allocation
2150 overhead and fragmentation by moving allocated regions around whenever it
2151 needs to. You always refer to a ralloc'd region with a "handle" (a
2152 pointer to a pointer--an object of type `void **').
2154 * There is a new `printf' format: `%m' gives you the string corresponding
2155 to the error code in `errno'.
2157 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
2158 or `%[' conversion, but instead of filling in a fixed-sized buffer you
2159 pass, the `a' modifier says to fill in a `char **' you pass with a
2160 malloc'd string.
2162 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
2163 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
2164 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
2166 * `mkstemp' is a traditional Unix function to atomically create and open a
2167 uniquely-named temporary file.
2168 \f
2169 Version 1.05
2171 * The standard location for the file that says what the local timezone is
2172 has changed again. It is now `/usr/local/etc/localtime' (or more
2173 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
2175 * The distribution no longer contains any files with names longer than 14
2176 characters.
2178 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
2179 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
2181 * New functions `ttyslot' and `syslog' from 4.4 BSD.
2182 \f
2183 Version 1.04
2185 * The configuration process has changed quite a bit. The `configure'
2186 script is now used just like the configuration scripts for other GNU
2187 packages. The `sysdeps' directory hierarchy is much rearranged.
2188 The file `INSTALL' explains the new scheme in detail.
2190 * The header files no longer need to be processed into ANSI C and
2191 traditional C versions. There is just one set of files to install, and
2192 it will work with ANSI or old C compilers (including `gcc -traditional').
2194 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
2195 MIPS DECStation running Ultrix 4.
2197 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
2198 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
2199 made itself into a shared library.
2201 * Yet further improved support for the i386, running 4.3 BSD-like systems
2202 (such as Mach 3 with the Unix single-server), or System V.
2204 * New function `strncasecmp' to do case-insensitive string comparison
2205 with limited length.
2207 * New function `strsep' is a reentrant alternative to `strtok'.
2209 * New functions `scandir' and `alphasort' for searching directories.
2211 * New function `setenv' is a better interface to `putenv'.
2213 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
2214 function for traversing a directory tree.
2216 * The GNU obstack package is now also part of the C library.
2217 The new function `open_obstack_stream' creates a stdio stream that
2218 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
2219 formatted output directly to an obstack.
2221 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
2222 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
2224 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
2226 * The new functions `strfry' and `memfrob' do mysterious and wonderful
2227 things to your strings.
2229 * There are some new test programs: test-fseek, testmb, and testrand.
2231 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
2232 These ports are not finished, but are a good starting place for really
2233 supporting those systems.
2235 * `/etc/localtime' is now the standard location for the file that says what
2236 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
2237 This follows the general principle that `/etc' is the place for all local
2238 configuration files.
2240 * The C library header files now use `extern "C"' when used by the C++
2241 compiler, so the C library should now work with C++ code.
2243 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
2244 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
2245 in <strings.h>.)
2247 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
2248 function which uses the `merge sort' algorithm, and is said to be
2249 significantly faster than the old GNU `qsort' function. Merge sort is
2250 now the standard `qsort' function. The new algorithm can require a lot
2251 of temporary storage; so, the old sorting function is called when the
2252 required storage is not available.
2254 * The C library now includes Michael Glad's Ultra Fast Crypt, which
2255 provides the Unix `crypt' function, plus some other entry points.
2257 * The code and header files taken from 4.4 BSD have been updated with the
2258 latest files released from Berkeley.
