UD
21* Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
22 charsets.
23
24* iconv (the program and the interface) now accepts empty names (excluding
25 options like //TRANSLIT) to mean "use charset of current locale".
47e8b443 26
bb0ec5bd 27* localedef can now transliterate characters in strings which are not in
47e8b443 28 the provided charmap. The information from the input locale is used.
c17f665b
UD
29
30* Prelinking support was added for ELF targets. This requires additional
31 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
8e57fc70 32
bb0ec5bd 33* Read-only stdio streams now use mmap to speed up operation by eliminating
91e6367e
UD
34 copying and buffer underflows. To use add 'm' to the mode string of
35 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
207b66ce

be45f421
UD
52
53* Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
62497f9c 54 EUC-JISX0213, and TISCII.
a753ffb2
RM
55
56* New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
57 BSD-compatible interface for getting all network interface addresses.
58 Implementation for IPv4 by Roland McGrath.
6a9340b5
UD
59
60* Loading of locale data is faster due to the introduction of a locale
61 archive. Implemented by Roland McGrath and Ulrich Drepper.
dd4f2115
UD
62
63* Startup times are significantly reduced by not using exported functions
64 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
65 and Ulrich Drepper.
c843e065
RM
66
67* Steven Munroe contributed a port to PowerPC64/Linux.
68\f
45061a15
RM
69Version 2.2.6
70
71* The Hurd now uses the GNU libio implementation of stdio rather than the
72 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
73
74* The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
75 with the same behavior as the Linux system call of the same name.
03a2c647 76\f
a8ae31c2
UD
77Version 2.2.5
78
76321a25
AJ

80 128-bit long double format.
a8ae31c2 81
557a9213
UD
82* Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
83 IBM1161, and IBM1162 charsets.
a8ae31c2 84

UD
89* libc functions using I/O streams now can handle wide-oriented streams
90 as well.
91
45061a15
RM
92* optimizations in the dynamic linker. Binaries created by recent binutils
93 versions start up quicker due to reduced time spent on relocations.
8e57fc70
UD
94
95* Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
7d0c5823 96\f

103 support Unicode 3.1.
86dbe05e
UD
104
105* Speed of regex for single-byte locales is back to previous levels.
106 Patch by Isamu Hasegawa.
045fcd26 107
69d5f925 108* Alpha, SPARC, and IA-64 now also using floating stacks.
045fcd26 109
69d5f925 110* Startup time of internationalized applications greatly improved through
045fcd26
UD
111 iconv cache. Use iconvconfig to generate the cache file.
112 Contributed by Ulrich Drepper.
113
114* The IA-64 specific part of ld.so was rewritten to eliminate some pretty
115 severe performance problems. Patch by David Mosberger.
116
117* The Hurd port got a lot more functionality like AIO, various stdio
118 extensions, etc. Mainly done by Roland McGrath.
129d706d
UD
119
120* mtrace can now lookup symbols in shared libraries.
33996419 121\f
2ace5721
UD
122Version 2.2.3
123
1746f2b0 124* Intel's IA-64 math library is largely integrated. It provides fast and
2ace5721
UD
125 accurate implementatations for most basic and standard math functions
126 in float, double, and long double format.
127
f128331c 128* Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
b8750342
UD
129 and asin for the 96-bit long double format and asin, log, tan for the
130 128-bit long double format.
07f951e4 131
e4d82761
UD
132* The beginning of a last-bit accurate math library by IBM Haifa were added.
133 The basic double functions exist today. Contributed by Abraham Ziv
134 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
135 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
136
2ace5721
UD
137* An asynchronous name lookup library was added. The interface is designed
138 after POSIX AIO. The proposal was circulated beforehand to get comments.
139 No negative ones came in. Implemented by Ulrich Drepper.
b8a8413c
UD
140
141* Port to S390/64bit contributed by Martin Schwidefsky
142 <schwidefsky@de.ibm.com>.
a66f0958
UD
143
144* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
145 of functions for Linux/IA-64.
481b550f
UD
146
147* The RPC code is now thread safe. Threads can now use the same service
148 of different services at the same time. Patch by Eric Norum
149 <eric.norum@usask.ca> with some help by Ulrich Drepper.
f128331c
UD
150
151* Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
152 family of functions for Linux/S390.
232fdf8c
UD
153
154* Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
155 of functions for Linux/x86.
eacde9d0
UD
156
157* Port to Linux/CRIS contributed by Axis Communications.
2ace5721 158\f
306eeae5
UD
159Version 2.2.2
160
464d97ec 161* Lots of headers were cleaned up. Using the tool in the conform/ subdir
306eeae5
UD
162 we can now check for namespace violations and missing declarations. The
163 result is that almost all headers are now Unix-compliant (as defined in
164 the upcoming XPG6). The negative side is that some programs might need
165 corrections, too, if they depend on the incorrect form of the headers in
166 previous versions which defined too many symbols and included too many
167 other headers.
464d97ec
UD
168
169* regex now handles multibyte character sets correctly.
170 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
171
172* iconv (the program) does now conform to the upcoming XPG6 and handles
173 charmaps. Instead of the charset names the path of charmaps can be
174 provided and the conversion happens based on this data.
175 Contributed by Ulrich Drepper.
176
177* The locale program now provides detailed information about the installed
178 locales. While
179
180 locale -a
181
182 only lists the names of the supported locales
183
184 locale -a --verbose
185
186 provides details such as country, language, and codeset name.
187 Contributed by Ulrich Drepper.
306eeae5 188\f
d2defdc4
UD
189Version 2.2.1
190
191* The gencat program now parses the input file according to the charset
192 selected by the LC_CTYPE category. This is important for stateful
193 character sets. To make generating catalogs easier there is a way
194 to overwrite the charset selected by the locale: before the first
195 message or $ quote line the catalog can contain a line like
196
197 $ codeset=ISO-8859-2
198
199 to select the charset (ISO-8859-2 in this case).
200
201 Implemented by Shinya Hanataka and Ulrich Drepper.
aea6353a
UD
202
203* New codeset conversion modules: IBM-922 (Estonia PC codeset),
204 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
205 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
234669e2
UD
206
207* Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
208 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
209
210* The LANGUAGE environment variable is now ignored unless the locale is
211 changed from the default "C" locale.
212
213* The usual bug fixes.
d2defdc4 214\f
2e92188d
UD
215Version 2.2
216
08a2e4a0
GM
217* Greg McGary added runtime support for bounds checking using gcc's
218 new -fbounded-pointers option. ix86 target is complete. PowerPC
219 is in progress.
220
2e92188d
UD
221* Thorsten Kukuk added secure mode support to nscd.
222
793bd4d9 223* The Berkeley db libraries have been removed.
2e92188d 224
47b853e8
UD
225 Related, the nss_db module is now in a separate package since it
226 obviously requires a database library being available.
227
0013b2b1
UD
228* Wide character I/O streams implemented by Ulrich Drepper.
229
abbffdf9 230* Functions from the extended socket API added by Ulrich Drepper.
01c771d0 231
6e8afc1c
UD
232* Functions feenableexcept and fedisableexcept to control the
233 behaviour of individual exceptions have been added by Andreas Jaeger.
234
591e1ffb
UD
235* ldconfig program added by Andreas Jaeger and Jakub Jelinek.
236
d3436b3c
UD
237* The resolver code has been updated from bind 8.2.3-T5B which supports
238 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
239 and Mark Kettenis.
2588068b
UD
240
241 This change could in some situations effect backward compatibility. Since
242 now `_res' is a thread-local instead of a global variable, modifying it
243 in one thread does not have any effect in other threads.
66ac0abe 244
a00c3ca9 245 The resolver library was also extended to allow IPv6 as the transport
d3436b3c
UD
246 protocol for the requests. This work was done by Stig Venaas.
247
1c5d4617
UD
248* Compatibility code for K&R C compilers has been removed from the
249 header files. A ISO C compiler is needed to use the library
250 (conforming to either C89 or C99 standard).
251
abbffdf9
UD
252* Complete rewrite of the localedef program to support multibyte character
253 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
254 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
255 Implemented by Ulrich Drepper.
256
8f3f1e09
UD
257 Bruno Haible significantly improved the generation and use of the data
258 structures for the wide character tables.
259
abbffdf9
UD
260* Plural handling in gettext implemented by Ulrich Drepper.
261
69173865
UD
262* The utmp daemon has been removed.
263
264* The port to MIPS-Linux has been finished by Andreas Jaeger.
265
37fb8add
UD
266* A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
267 and Yutaka Niibe.
268
594cee6c
UD
269* POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
270
40c4c9b5
UD
271* POSIX barriers implemented by Kaz Kylheku.
272
594cee6c
UD
273* POSIX spawn function family implemented by Ulrich Drepper.
274
275* POSIX spinlocks are now available.
276
40c4c9b5
UD
277* Timed wait functions for mutex, rwlock, and semaphores are implemented.
278
8f3f1e09
UD
279* the configure option --enable-kernel=X.Y.Z allows to strip out
280 compatibility for kernel versions before X.Y.Z. This is currently only
281 implemented for Linux.
282
3107c0c5
UD
283* the sockaddr_in6 structure changed. The IPv6 working group added a new
284 field sin6_scope_id. This means that all programs using IPv6 should be
285 recompiled. Don't expect binary compatibility with previous glibc
286 versions.
287
d2830ba4
UD
288* various conversion modules for IBM character sets contributed by
289 Masahide Washizawa.
290
8f3f1e09
UD
291* IA-64 port by Jes Sorensen and HJ Lu.

294Compiling the GNU C Library for Linux/ia64
295******************************************
296
297 Please refer to the file INSTALL in the same directory as you found
298this file for general information about configuring and compiling
299glibc.
300
301 For general inquiries about glibc under Linux/ia64 please use the
302following mailing list linux-ia64@linuxia64.org or one of the relevant
303glibc mailing lists.
304
305Recommended Tools for Compilation
306=================================
307
308 In order for glibc-2.2 to build correctly on the ia64 you need at
309least the following versions of the GNU tools (the :
310
311 * The Cygnus toolchain snapshot for the ia64 as of August 4
aea6353a
UD
312 including the provided set of patches. It is however recommend
313 you use the October 24 toolchain snapshot or a more recent version.
8f3f1e09
UD
314
315 OR alternatively you can try the following (the Cygnus toolchain is
316 the recommended solution):
317
318 * GCC and binutils, GAS and GNU LD out of CVS from
aea6353a 319 sources.redhat.com as of August 28, 2000 or later. The CVS tree
8f3f1e09
UD
320 may require special patches to work properly on the ia64.
321
322Configuring and compiling GNU Libc for Linux/ia64
323=================================================
324
325 The library requires Linux kernel version 2.4.0-test4-000728 or
aea6353a
UD
326later to funtion properly. Besides that it support for debug libraries
327is currently untested. Hence the following options
8f3f1e09
UD
328are required for configuring the library:
329
aea6353a 330 --disable-debug --enable-kernel=2.4.0
8f3f1e09
UD
331
332 It is also important that you make sure the library picks up the
333appropriate kernel header files, if you do not have recent enough
334kernel headers in /usr/src/linux/include, you should use the
335--with-headers=<path> option to specify the location.
336
337 As an example I personally use the following options to configure
338the library:
339
340 --disable-debug
8f3f1e09
UD
341 --disable-cvs
342 --enable-kernel=2.4.0
343 --host=ia64-linux
344 --enable-add-ons=yes
345 --prefix=/usr
346 --with-headers=/home/jes/linux/include
347
348
349Good luck

e518937a
UD
365Version 2.1.1
366
27995311
UD
367* New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
368
16b0f634
UD
369* New xdr functions are added; some rpc functions are now 64bit clean.
370
407d26b7 371* Fixed a number of bugs and memory leaks (especially in NIS+ code).
16b0f634
UD
372
373* Fixed known incompatibilities with glibc 2.0.

e518937a 385\f
c84142e8
UD
386Version 2.1
387
da2d1bc5
UD
388* Richard Henderson corrected size of struct timeval on Linux/Alpha to
389 conform to POSIX member type requirements. Symbol versions have been
390 adjusted as needed within the library, and for direct use by applications,
391 but there is potential for problems if third-party libraries use
392 struct timeval as part of their interface. This does not present
393 a problem for X and other "essential" system libraries.
394
c84142e8 395* An additional locale model to support C++ Standard Library locale
1fb05e3d 396 model and probably more was implemented by Ulrich Drepper.
c84142e8 397
1fb05e3d 398* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
c84142e8
UD
399 symbol level.

401* Miles Bader provided the `argp' function family to support hierachical
402 command line argument parsing, layered on top of getopt.
377a515b 403
cbdee279 404* strtod accepts new hexadecimal floating-point format from ISO C 9X.
377a515b
UD
405
406* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
cbdee279 407 numbers.
377a515b 408
cbdee279 409* scanf recognizes the %a and %A format for scanning floating point numbers.
e61abf83 410
48869012
UD
411* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
412 information and interfaces for the available integer types.
e61abf83 413
813f4f4d
UD
414* about 130 new math functions were added to implement the ISO C9x math
415 library.
416
e61abf83 417* the new header <complex.h> contains definitions of the complex math
cbdee279
UD
418 functions from ISO C 9X.
419
420* the new header <tgmath.h> defines generic macros to use complex or
421 real valued functions.
e61abf83 422
a5a0310d 423* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
e61abf83 424
a5a0310d
UD
425* Andreas Jaeger provided a test suite for the math library.

cbdee279 428
440d13e2 429* Ulrich Drepper added character set conversion functions (iconv).
cbdee279
UD
430
431* Optimized string functions have been added.

860\f
40a4b79f 861Version 2.0
28f540f4 862
d3669add
RM
863* GNU extensions are no longer declared by default. To enable them you
864 must define the macro `_GNU_SOURCE' in your program or compile with
865 `-D_GNU_SOURCE'.
866
28f540f4
RM
867* The library has changed from using GNU ld symbol aliases to using weak
868 symbols where available. The ELF object file format supports weak
869 symbols; GNU ld also supports weak symbols in the a.out format. (There
870 is also now support for other GNU ld extensions in ELF. Use the
787126fe
RM
871 `--with-elf' option to configure to indicate you have ELF, and
872 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
28f540f4
RM
873 of many files which contained only symbol aliases, reducing the size of
874 the source and the compiled library; many other files were renamed to
875 less cryptic names previously occupied by the symbol alias files.
dcf0671d
UD
876 There is a new header file <elf.h> for programs which operate on
877 files in the ELF format.
49e522bf
RM
878
879* Converted to Autoconf version 2, so `configure' has more options.
880 Run `configure --help' to see the details.
881
882* The library can now be configured to build profiling, highly-optimized
b25c5d66
RM
883 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
884 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
885 `configure' enable building these extra libraries. The shared library is
886 built by default when using both ELF and GNU ld. When shared libraries
887 are enabled, the new library `-ldl' is available for arbitrary run-time
888 loading of shared objects; its interface is defined in <dlfcn.h>. The
889 new header file <link.h> gives access to the internals of the run-time
33a934a3
UD
890 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
891 application of same name on other systems and it provides information
892 about dynamically linked binaries.
49e522bf 893
71733723
RM
894* The C library now provides the run-time support code for profiling
895 executables compiled with `-pg'. Programs can control the profiling code
d3669add
RM
896 through the interface in <sys/gmon.h>. The `gmon.out' files written by
897 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
898 the support for this file format was contributed by David Mosberger-Tang.
71733723 899
f7eac6eb 900* The math code has been replaced with a math library based on fdlibm from
33a934a3
UD
901 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
902 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
903 functions. The math functions now reside in a separate library, so
904 programs using them will need to use `-lm' their linking commands.
905
906* John C. Bowman contributed optimized ix87 assembler inline functions.
f7eac6eb 907
5f0e6fc7
RM
908* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
909 mechanism similar to that found in Solaris 2. This is now used for the
33a934a3
UD
910 group, passwd, hosts, networks, services, protocols, rpc, ethers,
911 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
912 file controls what services are used for each individual database. This
913 works by loading shared libraries with names specified in `nsswitch.conf',
914 so service modules can be changed or added at any time without even
915 relinking any program. Currently there are the file, db, and NIS based
916 NSS services available.
5f0e6fc7 917
49e522bf
RM
918* The new functions `strtoq' and `strtouq' parse integer values from
919 strings, like `strtol' and `strtoul', but they return `long long int' and
920 `unsigned long long int' values, respectively (64-bit quantities).
921
922* The new functions `strtof' and `strtold' parse floating-point values from
923 strings, like `strtod', but they return `float' and `long double' values,
924 respectively (on some machines `double' and `long double' are the same).
925
926* Ulrich Drepper has contributed new implementations of the floating-point
927 printing and reading code used in the `printf' family of functions and
928 `strtod', `strtof', and `strtold'. These new functions are perfectly
929 accurate, and much faster than the old ones.
930
33a934a3
UD
931* The implementation of the POSIX locale model was completely rewritten by
932 Ulrich Drepper. This includes the new programs `localedef' and `locale'
933 to compile the POSIX locale definition.
934
935* The former dummy implementations of the strcoll and strxfrm function are
936 now replaced by fully functional code contributed by Ulrich Drepper. The
937 collation information comes from the POSIX locale definitions.
938
49e522bf
RM
939* The new header <langinfo.h> defines an interface for accessing
940 various locale-dependent data (using the locale chosen with `setlocale').
941
f7eac6eb 942* Ulrich Drepper has contributed a new suite of functions for operation on
33a934a3 943 wide-character and multibyte-character strings, in <wchar.h>;
b7407d63 944 and classification and case conversion of wide characters, in <wctype.h>.
33a934a3
UD
945 These new functions are conforming to the ISO C, Amendement 1 specification.
946
947* There is now a second implementation of the standard I/O library available.
948 It comes from GNU libg++ as was written by Per Bothner, heavily modified
949 by Hongjiu Lu and made thread safe by Ulrich Drepper.
f7eac6eb 950
71733723 951* You can now use positional parameter specifications in format strings
49e522bf
RM
952 for the `printf' and `scanf' families of functions. For example,
953 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
954 ``Number 6, Mr Jones''. This is mainly useful when providing different
d365fd2c
RM
955 format strings for different languages, whose grammars may dictate
956 different orderings of the values being printed. To support this
49e522bf 957 feature, the interface for `register_printf_handler' has changed; see
d365fd2c 958 the header file <printf.h> for details.
49e522bf
RM
959
960* The `printf' and `scanf' families of functions now understand a new
961 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
962 to group numbers as indicated by the locale; for `scanf' and friends, this
963 says to accept as valid only a number with all the proper grouping
964 separators in the right places. In the default "C" locale, numbers are
965 not grouped; but locales for specific countries will define the usual
966 conventions (i.e. separate thousands with `,' in the US locale).
28f540f4
RM
967
968* The pgrp functions have been regularized, slightly incompatibly but much
969 less confusingly. The core functions are now `getpgid' and `setpgid',
970 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
971 argument) and BSD `setpgrp' (identical to `setpgid') functions are
972 provided for compatibility. There is no longer an incompatible `getpgrp'
973 with an argument declared under _BSD_SOURCE; no BSD code uses it.
974
975* The new header file <fts.h> and suite of functions simplify programs that
976 operate on directory trees. This code comes from 4.4 BSD.
977
33a934a3
UD
978* The resolver code has been updated from the BIND 4.9.5-P1 release.
979 Parts of the code were heavily modified by Ulrich Drepper to fit in the
980 NSS scheme used in glibc.
28f540f4 981
28f540f4
RM
982* There is a new malloc debugging hook `__memalign_hook'.
983
984* There are new typedefs `ushort' for `unsigned short int' and `uint' for
985 `unsigned int' in <sys/types.h>. These are for compatibility only and
986 their use is discouraged.
987
988* The `-lmcheck' library to enable standard malloc debugging hooks is now
989 done differently, so that it works even without GNU ld.
787126fe 990
22a1292a
RM
991* New function `euidaccess' checks allowed access to a file like `access',
992 but using the effective IDs instead of the real IDs.
49e522bf
RM
993
994* The time zone data files have been updated for the latest and greatest
995 local time conventions of the countries of the world.
996
997* The new function `dirfd' extracts the file descriptor used by a DIR stream;
998 see <dirent.h>.
999
1000* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
1001 for formatting floating-point numbers. They are provided only for
33a934a3
UD
1002 compatibility; new programs should use `sprintf' instead. There are
1003 also equivalent function for the `long double' floating-point type and
1004 all functions also exist in a reentrant form.
342414a6
RM
1005
1006* The new auxiliary library `-lutil' from 4.4 BSD contains various
1007 functions for maintaining the login-record files (primarily of use to
1008 system programs such as `login'), and convenient functions for
1009 allocating and initializing a pseudo-terminal (pty) device.
c709e372
RM
1010
1011* Ulrich Drepper has contributed new support for System V style
1012 shared memory and IPC on systems that support it.
1013
1014* Ulrich Drepper has contributed several miscellaneous new functions found
1015 in System V: The `hsearch' family of functions provide an effective
1016 implementation of hash tables; `a64l' and `l64a' provide a very simple
1017 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
1018 number generator.
1019
1020* Ulrich Drepper has contributed new reentrant counterparts for the
1021 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
1022
1023* Ulrich Drepper has contributed new, highly-optimized versions of several
1024 string functions for the i486/Pentium family of processors.
1025
71733723 1026* Ulrich Drepper has updated the Linux-specific code, based largely
c709e372 1027 on work done in Hongjiu Lu's version of GNU libc for Linux.
33a934a3
UD
1028 The GNU library now supports Linux versions 2.0.10 and later,
1029 using the ELF object file format (i[3456]86-*-linux).
c709e372 1030
d3669add
RM
1031* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
1032
33a934a3
UD
1033* David Mosberger-Tang and Richard Henderson have ported the C library
1034 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
1035 dynamic linking support for ELF/Alpha.
1036
1037* Richard Henderson contributed several Alpha optimized assembler function
1038 for arithmetic and string handling.
d3669add 1039
c709e372 1040* Ulrich Drepper has contributed a new set of message catalog functions to
40a4b79f
RM
1041 support multiple languages using the <libintl.h> interface, for use with
1042 his new package GNU gettext. Translation volunteers have contributed
1043 catalogs of the library's messages in Spanish, German, and Korean.
1044
1045* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
1046 program and the `catgets' function for reading the catalog files it
1047 creates. (The <libintl.h> interface is preferred; we include the
1048 <nl_types.h> interface using `catgets' only for source compatibility with
1049 programs already written to use it.)
71733723
RM
1050
1051* New header file <values.h> gives SVID-compatible names for <limits.h>
1052 constants.
1053
1054* Various new macros, declarations, and small header files for compatibility
1055 with 4.4 BSD.
1056
1057* New function `group_member' is a convenient way to check if a process has
1058 a given effective group ID.
1059
1060* When using GCC 2.7 and later, the socket functions are now declared in a
1061 special way so that passing an argument of type `struct sockaddr_in *',
1062 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
1063 `struct sockaddr *' type, does not generate a type-clash warning.
1064
1065* New function `error' declared in header file <error.h> is a convenient
6d52618b 1066 function for printing error messages and optionally exiting; this is the
71733723
RM
1067 canonical function used in GNU programs. The new functions `err', `warn',
1068 and friends in header file <err.h> are the canonical 4.4 BSD interface for
1069 doing the same thing.
1070
1071* The <glob.h> interface has several new flags from 4.4 BSD that extend the
1072 POSIX.2 `glob' function to do ~ and {...} expansion.
1073
1074* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
33a934a3 1075 `clearenv' which is used in POSIX.9 is also available.
71733723
RM
1076
1077* New function `getsid' returns session ID number on systems that support it.
1078
f7eac6eb
RM
1079* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1080 files <db.h> and <mpool.h> provide a rich set of functions for several
1081 types of simple databases stored in memory and in files, and <ndbm.h> is
6d52618b 1082 an old `ndbm'-compatible interface using the `db' functions. Link with
999493cb 1083 `-ldb' to get these functions.
f7eac6eb
RM
1084
1085* New macro `strdupa' copies a string like `strdup', but uses local stack
1086 space from `alloca' instead of dynamic heap space from `malloc'.
52e9a9d1
RM
1087
1088* New function `strnlen' is like `strlen' but searches only a given maximum
33a934a3
UD
1089 number of characters for the null terminator. `stpncpy', `strndup' and
1090 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1091 function.
40a4b79f
RM
1092
1093* New function `statfs' in header <sys/statfs.h>.
1094
1095* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1096 provide convenient functions for operating on blocks of null-terminated
1097 strings.
1098
1099* A new suite of functions in <utmp.h> handle all the details of reading
1100 and writing the utmp file.
33a934a3
UD
1101
1102* An implementation of the NIS/YP(tm) based NSS service was contributed by
1103 Thorsten Kukuk.
1104
1105* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1106 completely POSIX compliant and also implemented the extended functionality
1107 to handle alternate digit representation and alternate era date formats.
1108
1109* Ulrich Drepper provided an implementation of the `strptime' function
1110 defined in XPG4.2 which transforms a string into a `struct tm' value.
1111
1112* Paul Eggert provided the tzselect shell script as part of the timezone
1113 code. The shell script makes it easy to select the correct timezone
1114 specification.
1115
1116* The implementation of the malloc family of functions is completely replaced
1117 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1118 The implementation uses the mmap function (if available) and it is
1119 optimized for the use in multi threaded programs.
1120
1121* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1122 functions. This new functionality is usable by specifying a special
1123 salt string and it is compatible with implementation on *BSD systems.
1124
1125* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1126 `getsubopt' to handle second level command line options, `bsd_signal'
1127 to access BSD style `signal' functionality, the obsolete `regexp' style
1128 expression matcher.
1129
1130* the `lchown' function is available on system which support this
1131 functionality.
1132
1133* The implementation of the shadow password handling function was contributed
1134 by Ulrich Drepper.
1135
1136* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1137
1138* POSIX.1g support was added. The <sys/select.h> header is available,
1139 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1140 implementation of `getaddrinfo'.
28f540f4
RM
1141\f
1142Version 1.09
1143
1144* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
1145
1146* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
1147 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
1148
1149* The new function `daemon' from 4.4 BSD is useful for server programs that
1150 want to put themselves in the background.
1151
1152* Joel Sherrill has contributed support for several standalone boards that
1153 run without an operating system.
1154
1155* `printf', `scanf' and friends now accept a `q' type modifier for long
1156 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
1157
1158* All of the code taken from BSD (notably most of the math and networking
1159 routines) has been updated from the BSD 4.4-Lite release.
1160
1161* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
1162
1163* The new functions `getdomainname' and `setdomainname' fetch or change the
1164 YP/NIS domain name. These are system calls which exist on systems which
1165 have YP (aka NIS).
1166
1167* The time zone data files have been updated for the latest international
1168 conventions.
1169
1170* The SunRPC programs `portmap' and `rpcinfo' are now installed in
1171 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
1172\f
1173Version 1.08
1174
1175* The C library now includes support for Sun RPC, from Sun's free
1176 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
1177 are included. (There is still no support for YP.)
1178
1179* Tom Quinn has contributed a port of the C library to SGI machines running
1180 Irix 4 (mips-sgi-irix4).
1181
1182* The new `lockf' function is a simplified interface to the locking
1183 facilities of `fcntl', included for compatibility.
1184
1185* New time functions `timegm', `timelocal', and `dysize' for compatibility.
1186
1187* New header file <sys/timeb.h> and new function `ftime' for compatibility.
1188
1189* New header files <poll.h> and <sys/poll.h> and new function `poll' for
1190 compatibility.
1191
1192* The error message printed by `assert' for a failed assertion now includes
1193 the name of the program (if using GNU ld) and the name of the calling
1194 function (with versions of GCC that support this).
1195
1196* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
1197
1198* The library now includes the <sys/mman.h> header file and memory
1199 management functions `mmap', `munmap', `mprotect', `msync', and
1200 `madvise', on systems that support those facilities.
1201
1202* The interface for `mcheck' has changed slightly: the function called to
1203 abort the program when an allocation inconsistency is detected now takes
1204 an argument that indicates the type of failure. The new function
1205 `mprobe' lets you request a consistency check for a particular block at
1206 any time (checks are normally done only when you call `free' or `realloc'
1207 on a block).
1208
1209* It is now possible to easily cross-compile the C library, building on one
1210 system a library to run on another machine and/or operating system. All
1211 you need to do is set the variable `HOST_CC' in `configparms' to the
1212 native compiler for programs to run on the machine you are building on (a
1213 few generator programs are used on Unix systems); set `CC' to the
1214 cross-compiler.
1215
1216* The new function `fexecve' (only implemented on the GNU system) executes
1217 a program file given a file descriptor already open on the file.
1218\f
1219Version 1.07
1220
1221* Brendan Kehoe has contributed most of a port to the DEC Alpha
1222 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
1223
1224* You can set the variable `libprefix' in `configparms' to specify a prefix
1225 to be prepended to installed library files; this makes it easy to install
1226 the GNU C library to be linked as `-lgnuc' or whatever.
1227
1228* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
1229 copies a limited number of characters from a string, and returns the
1230 address of the last character written.
1231
1232* You no longer need to check for whether the installed `stddef.h' is
1233 compatible with the GNU C library. configure now checks for you.
1234
1235* You can now define a per-stream `fileno' function to convert the
1236 stream's cookie into an integral file descriptor.
1237
1238* ``malloc (0)'' no longer returns a null pointer. Instead, it
1239 allocates zero bytes of storage, and returns a unique pointer which
1240 you can pass to `realloc' or `free'. The behavior is undefined if
1241 you dereference this pointer.
1242
1243* The C library now runs on Sony NEWS m68k machines running either
1244 NewsOS 3 or NewsOS 4.
1245
1246* The new `syscall' function is a system-dependent primitive function
1247 for invoking system calls. It has the canonical behavior on Unix
1248 systems, including unreliable return values for some calls (such as
1249 `pipe', `fork' and `getppid').
1250
1251* The error code `EWOULDBLOCK' is now obsolete; it is always defined
1252 to `EAGAIN', which is the preferred name. On systems whose kernels
1253 use two distinct codes, the C library now translates EWOULDBLOCK to
1254 EAGAIN in every system call function.
1255\f
1256Version 1.06
1257
1258* The GNU C Library Reference Manual is now distributed with the library.
1259 `make dvi' will produce a DVI file of the printed manual.
1260 `make info' will produce Info files that you can read on line using C-h i
1261 in Emacs or the `info' program.
ea278354 1262 Please send comments on the manual to bug-glibc-manual@gnu.org.
28f540f4
RM
1263
1264* The library now supports SVR4 on i386s (i386-unknown-sysv4).
1265
1266* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
1267
1268* Jason Merrill has contributed a port to the Sequent Symmetry running
1269 Dynix version 3 (i386-sequent-dynix).
1270
1271* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
1272 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
1273
1274* New function `memory_warnings' lets you arrange to get warnings when
1275 malloc is running out of memory to allocate, like Emacs gives you.
1276
1277* The C library now contains the relocating allocator used in Emacs 19 for
1278 its editing buffers. This allocator (ralloc) minimizes allocation
1279 overhead and fragmentation by moving allocated regions around whenever it
1280 needs to. You always refer to a ralloc'd region with a "handle" (a
1281 pointer to a pointer--an object of type `void **').
1282
1283* There is a new `printf' format: `%m' gives you the string corresponding
1284 to the error code in `errno'.
1285
1286* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
1287 or `%[' conversion, but instead of filling in a fixed-sized buffer you
1288 pass, the `a' modifier says to fill in a `char **' you pass with a
1289 malloc'd string.
1290
1291* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
1292 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
1293 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
1294
1295* `mkstemp' is a traditional Unix function to atomically create and open a
1296 uniquely-named temporary file.
1297\f
1298Version 1.05
1299
1300* The standard location for the file that says what the local timezone is
1301 has changed again. It is now `/usr/local/etc/localtime' (or more
1302 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
1303
1304* The distribution no longer contains any files with names longer than 14
1305 characters.
1306
1307* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
1308 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
1309
1310* New functions `ttyslot' and `syslog' from 4.4 BSD.
1311\f
1312Version 1.04
1313
1314* The configuration process has changed quite a bit. The `configure'
1315 script is now used just like the configuration scripts for other GNU
1316 packages. The `sysdeps' directory hierarchy is much rearranged.
1317 The file `INSTALL' explains the new scheme in detail.
1318
1319* The header files no longer need to be processed into ANSI C and
1320 traditional C versions. There is just one set of files to install, and
1321 it will work with ANSI or old C compilers (including `gcc -traditional').
1322
1323* Brendan Kehoe and Ian Lance Taylor have ported the library to the
1324 MIPS DECStation running Ultrix 4.
1325
1326* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
1327 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
1328 made itself into a shared library.
1329
1330* Yet further improved support for the i386, running 4.3 BSD-like systems
1331 (such as Mach 3 with the Unix single-server), or System V.
1332
1333* New function `strncasecmp' to do case-insensitive string comparison
1334 with limited length.
1335
1336* New function `strsep' is a reentrant alternative to `strtok'.
1337
1338* New functions `scandir' and `alphasort' for searching directories.
1339
1340* New function `setenv' is a better interface to `putenv'.
1341
1342* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
1343 function for traversing a directory tree.
1344
1345* The GNU obstack package is now also part of the C library.
1346 The new function `open_obstack_stream' creates a stdio stream that
1347 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
1348 formatted output directly to an obstack.
1349
1350* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
1351 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
1352
1353* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
1354
1355* The new functions `strfry' and `memfrob' do mysterious and wonderful
1356 things to your strings.
1357
1358* There are some new test programs: test-fseek, testmb, and testrand.
1359
1360* Some work has been done to begin porting the library to 4.4 BSD and Linux.
1361 These ports are not finished, but are a good starting place for really
1362 supporting those systems.

1364* `/etc/localtime' is now the standard location for the file that says what
1365 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
1366 This follows the general principle that `/etc' is the place for all local
1367 configuration files.
1368
1369* The C library header files now use `extern "C"' when used by the C++
1370 compiler, so the C library should now work with C++ code.
1371
1372* The header file <bstring.h> is gone. <string.h> now declares bcopy,

UD
1373 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
1374 in <strings.h>.)

1376* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
1377 function which uses the `merge sort' algorithm, and is said to be
1378 significantly faster than the old GNU `qsort' function. Merge sort is
1379 now the standard `qsort' function. The new algorithm can require a lot
1380 of temporary storage; so, the old sorting function is called when the
1381 required storage is not available.
1382
1383* The C library now includes Michael Glad's Ultra Fast Crypt, which
1384 provides the Unix `crypt' function, plus some other entry points.

1386* The code and header files taken from 4.4 BSD have been updated with the
1387 latest files released from Berkeley.
