42 Contributed by Ulrich Drepper.
43
44* The IA-64 specific part of ld.so was rewritten to eliminate some pretty
45 severe performance problems. Patch by David Mosberger.
46
47* The Hurd port got a lot more functionality like AIO, various stdio
48 extensions, etc. Mainly done by Roland McGrath.
129d706d
UD
49
50* mtrace can now lookup symbols in shared libraries.
33996419 51\f
2ace5721
UD
52Version 2.2.3
53
1746f2b0 54* Intel's IA-64 math library is largely integrated. It provides fast and
2ace5721
UD
55 accurate implementatations for most basic and standard math functions
56 in float, double, and long double format.
57
f128331c 58* Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
b8750342
UD
59 and asin for the 96-bit long double format and asin, log, tan for the
60 128-bit long double format.
07f951e4 61
e4d82761
UD
62* The beginning of a last-bit accurate math library by IBM Haifa were added.
63 The basic double functions exist today. Contributed by Abraham Ziv
64 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
65 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
66
2ace5721
UD
67* An asynchronous name lookup library was added. The interface is designed
68 after POSIX AIO. The proposal was circulated beforehand to get comments.
69 No negative ones came in. Implemented by Ulrich Drepper.
b8a8413c
UD
70
71* Port to S390/64bit contributed by Martin Schwidefsky
72 <schwidefsky@de.ibm.com>.
a66f0958
UD
73
74* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
75 of functions for Linux/IA-64.
481b550f
UD
76
77* The RPC code is now thread safe. Threads can now use the same service
78 of different services at the same time. Patch by Eric Norum
79 <eric.norum@usask.ca> with some help by Ulrich Drepper.
f128331c
UD
80
81* Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
82 family of functions for Linux/S390.
232fdf8c
UD
83
84* Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
85 of functions for Linux/x86.
eacde9d0
UD
86
87* Port to Linux/CRIS contributed by Axis Communications.
2ace5721 88\f
306eeae5
UD
89Version 2.2.2
90
464d97ec 91* Lots of headers were cleaned up. Using the tool in the conform/ subdir
306eeae5
UD
92 we can now check for namespace violations and missing declarations. The
93 result is that almost all headers are now Unix-compliant (as defined in
94 the upcoming XPG6). The negative side is that some programs might need
95 corrections, too, if they depend on the incorrect form of the headers in
96 previous versions which defined too many symbols and included too many
97 other headers.
464d97ec
UD
98
99* regex now handles multibyte character sets correctly.
100 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
101
102* iconv (the program) does now conform to the upcoming XPG6 and handles
103 charmaps. Instead of the charset names the path of charmaps can be
104 provided and the conversion happens based on this data.
105 Contributed by Ulrich Drepper.
106
107* The locale program now provides detailed information about the installed
108 locales. While
109
110 locale -a
111
112 only lists the names of the supported locales
113
114 locale -a --verbose
115
116 provides details such as country, language, and codeset name.
117 Contributed by Ulrich Drepper.
306eeae5 118\f
d2defdc4
UD
119Version 2.2.1
120
121* The gencat program now parses the input file according to the charset
122 selected by the LC_CTYPE category. This is important for stateful
123 character sets. To make generating catalogs easier there is a way
124 to overwrite the charset selected by the locale: before the first
125 message or $ quote line the catalog can contain a line like
126
127 $ codeset=ISO-8859-2
128
129 to select the charset (ISO-8859-2 in this case).
130
131 Implemented by Shinya Hanataka and Ulrich Drepper.
aea6353a
UD
132
133* New codeset conversion modules: IBM-922 (Estonia PC codeset),
134 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
135 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
234669e2
UD
136
137* Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
138 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
139
140* The LANGUAGE environment variable is now ignored unless the locale is
141 changed from the default "C" locale.
142
143* The usual bug fixes.
d2defdc4 144\f
2e92188d
UD
145Version 2.2
146
08a2e4a0
GM
147* Greg McGary added runtime support for bounds checking using gcc's
148 new -fbounded-pointers option. ix86 target is complete. PowerPC
149 is in progress.
150
2e92188d
UD
151* Thorsten Kukuk added secure mode support to nscd.
152
793bd4d9 153* The Berkeley db libraries have been removed.
2e92188d 154
47b853e8
UD
155 Related, the nss_db module is now in a separate package since it
156 obviously requires a database library being available.
157
0013b2b1
UD
158* Wide character I/O streams implemented by Ulrich Drepper.
159
abbffdf9 160* Functions from the extended socket API added by Ulrich Drepper.
01c771d0 161
6e8afc1c
UD
162* Functions feenableexcept and fedisableexcept to control the
163 behaviour of individual exceptions have been added by Andreas Jaeger.
164
591e1ffb
UD
165* ldconfig program added by Andreas Jaeger and Jakub Jelinek.
166
d3436b3c
UD
167* The resolver code has been updated from bind 8.2.3-T5B which supports
168 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
169 and Mark Kettenis.
2588068b
UD
170
171 This change could in some situations effect backward compatibility. Since
172 now `_res' is a thread-local instead of a global variable, modifying it
173 in one thread does not have any effect in other threads.
66ac0abe 174
a00c3ca9 175 The resolver library was also extended to allow IPv6 as the transport
d3436b3c
UD
176 protocol for the requests. This work was done by Stig Venaas.
177
1c5d4617
UD
178* Compatibility code for K&R C compilers has been removed from the
179 header files. A ISO C compiler is needed to use the library
180 (conforming to either C89 or C99 standard).
181
abbffdf9
UD
182* Complete rewrite of the localedef program to support multibyte character
183 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
184 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
185 Implemented by Ulrich Drepper.
186
8f3f1e09
UD
187 Bruno Haible significantly improved the generation and use of the data
188 structures for the wide character tables.
189
abbffdf9
UD
190* Plural handling in gettext implemented by Ulrich Drepper.
191
69173865
UD
192* The utmp daemon has been removed.
193
194* The port to MIPS-Linux has been finished by Andreas Jaeger.
195
37fb8add
UD
196* A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
197 and Yutaka Niibe.
198
594cee6c
UD
199* POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
200
40c4c9b5
UD
201* POSIX barriers implemented by Kaz Kylheku.
202
594cee6c
UD
203* POSIX spawn function family implemented by Ulrich Drepper.
204
205* POSIX spinlocks are now available.
206
40c4c9b5
UD
207* Timed wait functions for mutex, rwlock, and semaphores are implemented.
208
8f3f1e09
UD
209* the configure option --enable-kernel=X.Y.Z allows to strip out
210 compatibility for kernel versions before X.Y.Z. This is currently only
211 implemented for Linux.
212
3107c0c5
UD
213* the sockaddr_in6 structure changed. The IPv6 working group added a new
214 field sin6_scope_id. This means that all programs using IPv6 should be
215 recompiled. Don't expect binary compatibility with previous glibc
216 versions.
217
d2830ba4
UD
218* various conversion modules for IBM character sets contributed by
219 Masahide Washizawa.
220
8f3f1e09
UD
221* IA-64 port by Jes Sorensen and HJ Lu.

224Compiling the GNU C Library for Linux/ia64
225******************************************
226
227 Please refer to the file INSTALL in the same directory as you found
228this file for general information about configuring and compiling
229glibc.
230
231 For general inquiries about glibc under Linux/ia64 please use the
232following mailing list linux-ia64@linuxia64.org or one of the relevant
233glibc mailing lists.
234
235Recommended Tools for Compilation
236=================================
237
238 In order for glibc-2.2 to build correctly on the ia64 you need at
239least the following versions of the GNU tools (the :
240
241 * The Cygnus toolchain snapshot for the ia64 as of August 4
aea6353a
UD
242 including the provided set of patches. It is however recommend
243 you use the October 24 toolchain snapshot or a more recent version.
8f3f1e09
UD
244
245 OR alternatively you can try the following (the Cygnus toolchain is
246 the recommended solution):
247
248 * GCC and binutils, GAS and GNU LD out of CVS from
aea6353a 249 sources.redhat.com as of August 28, 2000 or later. The CVS tree
8f3f1e09
UD
250 may require special patches to work properly on the ia64.
251
252Configuring and compiling GNU Libc for Linux/ia64
253=================================================
254
255 The library requires Linux kernel version 2.4.0-test4-000728 or
aea6353a
UD
256later to funtion properly. Besides that it support for debug libraries
257is currently untested. Hence the following options
8f3f1e09
UD
258are required for configuring the library:
259
aea6353a 260 --disable-debug --enable-kernel=2.4.0
8f3f1e09
UD
261
262 It is also important that you make sure the library picks up the
263appropriate kernel header files, if you do not have recent enough
264kernel headers in /usr/src/linux/include, you should use the
265--with-headers=<path> option to specify the location.
266
267 As an example I personally use the following options to configure
268the library:
269
270 --disable-debug
8f3f1e09
UD
271 --disable-cvs
272 --enable-kernel=2.4.0
273 --host=ia64-linux
274 --enable-add-ons=yes
275 --prefix=/usr
276 --with-headers=/home/jes/linux/include
277
278
279Good luck

UD
295Version 2.1.1
296
27995311
UD
297* New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
298
16b0f634
UD
299* New xdr functions are added; some rpc functions are now 64bit clean.
300
407d26b7 301* Fixed a number of bugs and memory leaks (especially in NIS+ code).
16b0f634
UD
302
303* Fixed known incompatibilities with glibc 2.0.
304
407d26b7 305* New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
16b0f634 306

e518937a 315\f
c84142e8
UD
316Version 2.1
317
da2d1bc5
UD
318* Richard Henderson corrected size of struct timeval on Linux/Alpha to
319 conform to POSIX member type requirements. Symbol versions have been
320 adjusted as needed within the library, and for direct use by applications,
321 but there is potential for problems if third-party libraries use
322 struct timeval as part of their interface. This does not present
323 a problem for X and other "essential" system libraries.
324
c84142e8 325* An additional locale model to support C++ Standard Library locale
1fb05e3d 326 model and probably more was implemented by Ulrich Drepper.
c84142e8 327
1fb05e3d 328* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
c84142e8
UD
329 symbol level.
330
331* Miles Bader provided the `argp' function family to support hierachical
332 command line argument parsing, layered on top of getopt.
377a515b 333
cbdee279 334* strtod accepts new hexadecimal floating-point format from ISO C 9X.
377a515b
UD
335
336* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
cbdee279 337 numbers.
377a515b 338
cbdee279 339* scanf recognizes the %a and %A format for scanning floating point numbers.
e61abf83 340
48869012
UD
341* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
342 information and interfaces for the available integer types.
e61abf83 343
813f4f4d
UD
344* about 130 new math functions were added to implement the ISO C9x math
345 library.
346
e61abf83 347* the new header <complex.h> contains definitions of the complex math
cbdee279
UD
348 functions from ISO C 9X.
349
350* the new header <tgmath.h> defines generic macros to use complex or
351 real valued functions.
e61abf83 352
a5a0310d 353* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
e61abf83 354
a5a0310d
UD
355* Andreas Jaeger provided a test suite for the math library.
356
357* Mark Kettenis implemented the utmpx interface and an utmp daemon.
cbdee279 358
440d13e2 359* Ulrich Drepper added character set conversion functions (iconv).
cbdee279
UD
360
361* Optimized string functions have been added.
362
363* The localedata addon is now part of glibc.
2eb45444
UD
364
365* An implementation of profiling shared libraries was added by Ulrich Drepper.
ea278354 366
48244d09
UD
367* Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
368 daemon for NSS (nscd).
369
370 Missing a better place here are some numbers on improvements. Under
371 Linux 2.1.125 un-tar-ing the kernel sources takes

387 Keep in mind that non-namelookup related operations dominate above times.
388 It was just a common complain that using NIS+ unpacking the kernel is
0dee6738 389 horribly slow.
48244d09 390
0dee6738
UD
391 [1] The old nscd implementation is not available anymore since it was
392 distributed with glibc up to version 2.0.98 and thus is now replaced.
ea278354
UD
393
394* Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
48869012
UD
395
396* Mark Kettenis provided a Hesiod NSS module.
20833331
UD
397
398* The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
399 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
400
401* rcmd can now handle netgroups (Dick Streefland).
48244d09 402
62595351
UD
403* A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
404 Bambrough.

40a4b79f 791Version 2.0
28f540f4 792
d3669add
RM
793* GNU extensions are no longer declared by default. To enable them you
794 must define the macro `_GNU_SOURCE' in your program or compile with
795 `-D_GNU_SOURCE'.
796
28f540f4
RM
797* The library has changed from using GNU ld symbol aliases to using weak
798 symbols where available. The ELF object file format supports weak
799 symbols; GNU ld also supports weak symbols in the a.out format. (There
800 is also now support for other GNU ld extensions in ELF. Use the
787126fe
RM
801 `--with-elf' option to configure to indicate you have ELF, and
802 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
28f540f4
RM
803 of many files which contained only symbol aliases, reducing the size of
804 the source and the compiled library; many other files were renamed to
805 less cryptic names previously occupied by the symbol alias files.
dcf0671d
UD
806 There is a new header file <elf.h> for programs which operate on
807 files in the ELF format.
49e522bf
RM
808
809* Converted to Autoconf version 2, so `configure' has more options.
810 Run `configure --help' to see the details.
811
812* The library can now be configured to build profiling, highly-optimized
b25c5d66
RM
813 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
814 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
815 `configure' enable building these extra libraries. The shared library is
816 built by default when using both ELF and GNU ld. When shared libraries
817 are enabled, the new library `-ldl' is available for arbitrary run-time
818 loading of shared objects; its interface is defined in <dlfcn.h>. The
819 new header file <link.h> gives access to the internals of the run-time
33a934a3
UD
820 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
821 application of same name on other systems and it provides information
822 about dynamically linked binaries.
49e522bf 823
71733723
RM
824* The C library now provides the run-time support code for profiling
825 executables compiled with `-pg'. Programs can control the profiling code
d3669add
RM
826 through the interface in <sys/gmon.h>. The `gmon.out' files written by
827 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
828 the support for this file format was contributed by David Mosberger-Tang.
71733723 829
f7eac6eb 830* The math code has been replaced with a math library based on fdlibm from
33a934a3
UD
831 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
832 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
833 functions. The math functions now reside in a separate library, so
834 programs using them will need to use `-lm' their linking commands.
835
836* John C. Bowman contributed optimized ix87 assembler inline functions.
f7eac6eb 837
5f0e6fc7
RM
838* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
839 mechanism similar to that found in Solaris 2. This is now used for the
33a934a3
UD
840 group, passwd, hosts, networks, services, protocols, rpc, ethers,
841 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
842 file controls what services are used for each individual database. This
843 works by loading shared libraries with names specified in `nsswitch.conf',
844 so service modules can be changed or added at any time without even
845 relinking any program. Currently there are the file, db, and NIS based
846 NSS services available.
5f0e6fc7 847
49e522bf
RM
848* The new functions `strtoq' and `strtouq' parse integer values from
849 strings, like `strtol' and `strtoul', but they return `long long int' and
850 `unsigned long long int' values, respectively (64-bit quantities).
851
852* The new functions `strtof' and `strtold' parse floating-point values from
853 strings, like `strtod', but they return `float' and `long double' values,
854 respectively (on some machines `double' and `long double' are the same).
855
856* Ulrich Drepper has contributed new implementations of the floating-point
857 printing and reading code used in the `printf' family of functions and
858 `strtod', `strtof', and `strtold'. These new functions are perfectly
859 accurate, and much faster than the old ones.
860
33a934a3
UD
861* The implementation of the POSIX locale model was completely rewritten by
862 Ulrich Drepper. This includes the new programs `localedef' and `locale'
863 to compile the POSIX locale definition.
864
865* The former dummy implementations of the strcoll and strxfrm function are
866 now replaced by fully functional code contributed by Ulrich Drepper. The
867 collation information comes from the POSIX locale definitions.
868
49e522bf
RM
869* The new header <langinfo.h> defines an interface for accessing
870 various locale-dependent data (using the locale chosen with `setlocale').
871
f7eac6eb 872* Ulrich Drepper has contributed a new suite of functions for operation on
33a934a3 873 wide-character and multibyte-character strings, in <wchar.h>;
b7407d63 874 and classification and case conversion of wide characters, in <wctype.h>.
33a934a3
UD
875 These new functions are conforming to the ISO C, Amendement 1 specification.
876
877* There is now a second implementation of the standard I/O library available.
878 It comes from GNU libg++ as was written by Per Bothner, heavily modified
879 by Hongjiu Lu and made thread safe by Ulrich Drepper.
f7eac6eb 880
71733723 881* You can now use positional parameter specifications in format strings
49e522bf
RM
882 for the `printf' and `scanf' families of functions. For example,
883 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
884 ``Number 6, Mr Jones''. This is mainly useful when providing different
d365fd2c
RM
885 format strings for different languages, whose grammars may dictate
886 different orderings of the values being printed. To support this
49e522bf 887 feature, the interface for `register_printf_handler' has changed; see
d365fd2c 888 the header file <printf.h> for details.
49e522bf
RM
889
890* The `printf' and `scanf' families of functions now understand a new
891 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
892 to group numbers as indicated by the locale; for `scanf' and friends, this
893 says to accept as valid only a number with all the proper grouping
894 separators in the right places. In the default "C" locale, numbers are
895 not grouped; but locales for specific countries will define the usual
896 conventions (i.e. separate thousands with `,' in the US locale).
28f540f4
RM
897
898* The pgrp functions have been regularized, slightly incompatibly but much
899 less confusingly. The core functions are now `getpgid' and `setpgid',
900 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
901 argument) and BSD `setpgrp' (identical to `setpgid') functions are
902 provided for compatibility. There is no longer an incompatible `getpgrp'
903 with an argument declared under _BSD_SOURCE; no BSD code uses it.
904
905* The new header file <fts.h> and suite of functions simplify programs that
906 operate on directory trees. This code comes from 4.4 BSD.
907
33a934a3
UD
908* The resolver code has been updated from the BIND 4.9.5-P1 release.
909 Parts of the code were heavily modified by Ulrich Drepper to fit in the
910 NSS scheme used in glibc.
28f540f4 911
28f540f4
RM
912* There is a new malloc debugging hook `__memalign_hook'.
913
914* There are new typedefs `ushort' for `unsigned short int' and `uint' for
915 `unsigned int' in <sys/types.h>. These are for compatibility only and
916 their use is discouraged.
917
918* The `-lmcheck' library to enable standard malloc debugging hooks is now
919 done differently, so that it works even without GNU ld.
787126fe 920
22a1292a
RM
921* New function `euidaccess' checks allowed access to a file like `access',
922 but using the effective IDs instead of the real IDs.
49e522bf
RM
923
924* The time zone data files have been updated for the latest and greatest
925 local time conventions of the countries of the world.
926
927* The new function `dirfd' extracts the file descriptor used by a DIR stream;
928 see <dirent.h>.
929
930* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
931 for formatting floating-point numbers. They are provided only for
33a934a3
UD
932 compatibility; new programs should use `sprintf' instead. There are
933 also equivalent function for the `long double' floating-point type and
934 all functions also exist in a reentrant form.
342414a6
RM
935
936* The new auxiliary library `-lutil' from 4.4 BSD contains various
937 functions for maintaining the login-record files (primarily of use to
938 system programs such as `login'), and convenient functions for
939 allocating and initializing a pseudo-terminal (pty) device.
c709e372
RM
940
941* Ulrich Drepper has contributed new support for System V style
942 shared memory and IPC on systems that support it.
943
944* Ulrich Drepper has contributed several miscellaneous new functions found
945 in System V: The `hsearch' family of functions provide an effective
946 implementation of hash tables; `a64l' and `l64a' provide a very simple
947 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
948 number generator.
949
950* Ulrich Drepper has contributed new reentrant counterparts for the
951 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
952
953* Ulrich Drepper has contributed new, highly-optimized versions of several
954 string functions for the i486/Pentium family of processors.
955
71733723 956* Ulrich Drepper has updated the Linux-specific code, based largely
c709e372 957 on work done in Hongjiu Lu's version of GNU libc for Linux.
33a934a3
UD
958 The GNU library now supports Linux versions 2.0.10 and later,
959 using the ELF object file format (i[3456]86-*-linux).
c709e372 960
d3669add
RM
961* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
962
33a934a3
UD
963* David Mosberger-Tang and Richard Henderson have ported the C library
964 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
965 dynamic linking support for ELF/Alpha.
966
967* Richard Henderson contributed several Alpha optimized assembler function
968 for arithmetic and string handling.
d3669add 969
c709e372 970* Ulrich Drepper has contributed a new set of message catalog functions to
40a4b79f
RM
971 support multiple languages using the <libintl.h> interface, for use with
972 his new package GNU gettext. Translation volunteers have contributed
973 catalogs of the library's messages in Spanish, German, and Korean.
974
975* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
976 program and the `catgets' function for reading the catalog files it
977 creates. (The <libintl.h> interface is preferred; we include the
978 <nl_types.h> interface using `catgets' only for source compatibility with
979 programs already written to use it.)
71733723
RM
980
981* New header file <values.h> gives SVID-compatible names for <limits.h>
982 constants.
983
984* Various new macros, declarations, and small header files for compatibility
985 with 4.4 BSD.
986
987* New function `group_member' is a convenient way to check if a process has
988 a given effective group ID.
989
990* When using GCC 2.7 and later, the socket functions are now declared in a
991 special way so that passing an argument of type `struct sockaddr_in *',
992 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
993 `struct sockaddr *' type, does not generate a type-clash warning.
994
995* New function `error' declared in header file <error.h> is a convenient
6d52618b 996 function for printing error messages and optionally exiting; this is the
71733723
RM
997 canonical function used in GNU programs. The new functions `err', `warn',
998 and friends in header file <err.h> are the canonical 4.4 BSD interface for
999 doing the same thing.
1000
1001* The <glob.h> interface has several new flags from 4.4 BSD that extend the
1002 POSIX.2 `glob' function to do ~ and {...} expansion.
1003
1004* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
33a934a3 1005 `clearenv' which is used in POSIX.9 is also available.
71733723
RM
1006
1007* New function `getsid' returns session ID number on systems that support it.
1008
f7eac6eb
RM
1009* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1010 files <db.h> and <mpool.h> provide a rich set of functions for several
1011 types of simple databases stored in memory and in files, and <ndbm.h> is
6d52618b 1012 an old `ndbm'-compatible interface using the `db' functions. Link with
999493cb 1013 `-ldb' to get these functions.
f7eac6eb
RM
1014
1015* New macro `strdupa' copies a string like `strdup', but uses local stack
1016 space from `alloca' instead of dynamic heap space from `malloc'.
52e9a9d1
RM
1017
1018* New function `strnlen' is like `strlen' but searches only a given maximum
33a934a3
UD
1019 number of characters for the null terminator. `stpncpy', `strndup' and
1020 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1021 function.
40a4b79f
RM
1022
1023* New function `statfs' in header <sys/statfs.h>.
1024
1025* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1026 provide convenient functions for operating on blocks of null-terminated
1027 strings.
1028
1029* A new suite of functions in <utmp.h> handle all the details of reading
1030 and writing the utmp file.
33a934a3
UD
1031
1032* An implementation of the NIS/YP(tm) based NSS service was contributed by
1033 Thorsten Kukuk.
1034
1035* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1036 completely POSIX compliant and also implemented the extended functionality
1037 to handle alternate digit representation and alternate era date formats.
1038
1039* Ulrich Drepper provided an implementation of the `strptime' function
1040 defined in XPG4.2 which transforms a string into a `struct tm' value.
1041
1042* Paul Eggert provided the tzselect shell script as part of the timezone
1043 code. The shell script makes it easy to select the correct timezone
1044 specification.
1045
1046* The implementation of the malloc family of functions is completely replaced
1047 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1048 The implementation uses the mmap function (if available) and it is
1049 optimized for the use in multi threaded programs.
1050
1051* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1052 functions. This new functionality is usable by specifying a special
1053 salt string and it is compatible with implementation on *BSD systems.
1054
1055* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1056 `getsubopt' to handle second level command line options, `bsd_signal'
1057 to access BSD style `signal' functionality, the obsolete `regexp' style
1058 expression matcher.
1059
1060* the `lchown' function is available on system which support this
1061 functionality.
1062
1063* The implementation of the shadow password handling function was contributed
1064 by Ulrich Drepper.
1065
1066* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1067
1068* POSIX.1g support was added. The <sys/select.h> header is available,
1069 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1070 implementation of `getaddrinfo'.
28f540f4
RM
1071\f
1072Version 1.09
1073
1074* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
1075
1076* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
1077 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
1078
1079* The new function `daemon' from 4.4 BSD is useful for server programs that
1080 want to put themselves in the background.
1081
1082* Joel Sherrill has contributed support for several standalone boards that
1083 run without an operating system.
1084
1085* `printf', `scanf' and friends now accept a `q' type modifier for long
1086 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
1087
1088* All of the code taken from BSD (notably most of the math and networking
1089 routines) has been updated from the BSD 4.4-Lite release.
1090
1091* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
1092
1093* The new functions `getdomainname' and `setdomainname' fetch or change the
1094 YP/NIS domain name. These are system calls which exist on systems which
1095 have YP (aka NIS).
1096
1097* The time zone data files have been updated for the latest international
1098 conventions.
1099
1100* The SunRPC programs `portmap' and `rpcinfo' are now installed in
1101 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
1102\f
1103Version 1.08
1104
1105* The C library now includes support for Sun RPC, from Sun's free
1106 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
1107 are included. (There is still no support for YP.)
1108
1109* Tom Quinn has contributed a port of the C library to SGI machines running
1110 Irix 4 (mips-sgi-irix4).
1111
1112* The new `lockf' function is a simplified interface to the locking
1113 facilities of `fcntl', included for compatibility.
1114
1115* New time functions `timegm', `timelocal', and `dysize' for compatibility.
1116
1117* New header file <sys/timeb.h> and new function `ftime' for compatibility.
1118
1119* New header files <poll.h> and <sys/poll.h> and new function `poll' for
1120 compatibility.
1121
1122* The error message printed by `assert' for a failed assertion now includes
1123 the name of the program (if using GNU ld) and the name of the calling
1124 function (with versions of GCC that support this).
1125
1126* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
1127
1128* The library now includes the <sys/mman.h> header file and memory
1129 management functions `mmap', `munmap', `mprotect', `msync', and
1130 `madvise', on systems that support those facilities.
1131
1132* The interface for `mcheck' has changed slightly: the function called to
1133 abort the program when an allocation inconsistency is detected now takes
1134 an argument that indicates the type of failure. The new function
1135 `mprobe' lets you request a consistency check for a particular block at
1136 any time (checks are normally done only when you call `free' or `realloc'
1137 on a block).
1138
1139* It is now possible to easily cross-compile the C library, building on one
1140 system a library to run on another machine and/or operating system. All
1141 you need to do is set the variable `HOST_CC' in `configparms' to the
1142 native compiler for programs to run on the machine you are building on (a
1143 few generator programs are used on Unix systems); set `CC' to the
1144 cross-compiler.
1145
1146* The new function `fexecve' (only implemented on the GNU system) executes
1147 a program file given a file descriptor already open on the file.
1148\f
1149Version 1.07
1150
1151* Brendan Kehoe has contributed most of a port to the DEC Alpha
1152 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
1153
1154* You can set the variable `libprefix' in `configparms' to specify a prefix
1155 to be prepended to installed library files; this makes it easy to install
1156 the GNU C library to be linked as `-lgnuc' or whatever.
1157
1158* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
1159 copies a limited number of characters from a string, and returns the
1160 address of the last character written.
1161
1162* You no longer need to check for whether the installed `stddef.h' is
1163 compatible with the GNU C library. configure now checks for you.
1164
1165* You can now define a per-stream `fileno' function to convert the
1166 stream's cookie into an integral file descriptor.
1167
1168* ``malloc (0)'' no longer returns a null pointer. Instead, it
1169 allocates zero bytes of storage, and returns a unique pointer which
1170 you can pass to `realloc' or `free'. The behavior is undefined if
1171 you dereference this pointer.
1172
1173* The C library now runs on Sony NEWS m68k machines running either
1174 NewsOS 3 or NewsOS 4.
1175
1176* The new `syscall' function is a system-dependent primitive function
1177 for invoking system calls. It has the canonical behavior on Unix
1178 systems, including unreliable return values for some calls (such as
1179 `pipe', `fork' and `getppid').
1180
1181* The error code `EWOULDBLOCK' is now obsolete; it is always defined
1182 to `EAGAIN', which is the preferred name. On systems whose kernels
1183 use two distinct codes, the C library now translates EWOULDBLOCK to
1184 EAGAIN in every system call function.
1185\f
1186Version 1.06
1187
1188* The GNU C Library Reference Manual is now distributed with the library.
1189 `make dvi' will produce a DVI file of the printed manual.
1190 `make info' will produce Info files that you can read on line using C-h i
1191 in Emacs or the `info' program.
ea278354 1192 Please send comments on the manual to bug-glibc-manual@gnu.org.
28f540f4
RM
1193
1194* The library now supports SVR4 on i386s (i386-unknown-sysv4).
1195
1196* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
1197
1198* Jason Merrill has contributed a port to the Sequent Symmetry running
1199 Dynix version 3 (i386-sequent-dynix).
1200
1201* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
1202 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
1203
1204* New function `memory_warnings' lets you arrange to get warnings when
1205 malloc is running out of memory to allocate, like Emacs gives you.
1206
1207* The C library now contains the relocating allocator used in Emacs 19 for
1208 its editing buffers. This allocator (ralloc) minimizes allocation
1209 overhead and fragmentation by moving allocated regions around whenever it
1210 needs to. You always refer to a ralloc'd region with a "handle" (a
1211 pointer to a pointer--an object of type `void **').
1212
1213* There is a new `printf' format: `%m' gives you the string corresponding
1214 to the error code in `errno'.
1215
1216* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
1217 or `%[' conversion, but instead of filling in a fixed-sized buffer you
1218 pass, the `a' modifier says to fill in a `char **' you pass with a
1219 malloc'd string.
1220
1221* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
1222 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
1223 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
1224
1225* `mkstemp' is a traditional Unix function to atomically create and open a
1226 uniquely-named temporary file.
1227\f
1228Version 1.05
1229
1230* The standard location for the file that says what the local timezone is
1231 has changed again. It is now `/usr/local/etc/localtime' (or more
1232 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
1233
1234* The distribution no longer contains any files with names longer than 14
1235 characters.
1236
1237* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
1238 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
1239
1240* New functions `ttyslot' and `syslog' from 4.4 BSD.
1241\f
1242Version 1.04
1243
1244* The configuration process has changed quite a bit. The `configure'
1245 script is now used just like the configuration scripts for other GNU
1246 packages. The `sysdeps' directory hierarchy is much rearranged.
1247 The file `INSTALL' explains the new scheme in detail.
1248
1249* The header files no longer need to be processed into ANSI C and
1250 traditional C versions. There is just one set of files to install, and
1251 it will work with ANSI or old C compilers (including `gcc -traditional').
1252
1253* Brendan Kehoe and Ian Lance Taylor have ported the library to the
1254 MIPS DECStation running Ultrix 4.
1255
1256* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
1257 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
1258 made itself into a shared library.
1259
1260* Yet further improved support for the i386, running 4.3 BSD-like systems
1261 (such as Mach 3 with the Unix single-server), or System V.
1262
1263* New function `strncasecmp' to do case-insensitive string comparison
1264 with limited length.
1265
1266* New function `strsep' is a reentrant alternative to `strtok'.
1267
1268* New functions `scandir' and `alphasort' for searching directories.
1269
1270* New function `setenv' is a better interface to `putenv'.
1271
1272* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
1273 function for traversing a directory tree.
1274
1275* The GNU obstack package is now also part of the C library.
1276 The new function `open_obstack_stream' creates a stdio stream that
1277 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
1278 formatted output directly to an obstack.
1279
1280* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
1281 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
1282
1283* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
1284
1285* The new functions `strfry' and `memfrob' do mysterious and wonderful
1286 things to your strings.
1287
1288* There are some new test programs: test-fseek, testmb, and testrand.
1289
1290* Some work has been done to begin porting the library to 4.4 BSD and Linux.
1291 These ports are not finished, but are a good starting place for really
1292 supporting those systems.
1293
1294* `/etc/localtime' is now the standard location for the file that says what
1295 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
1296 This follows the general principle that `/etc' is the place for all local
1297 configuration files.
1298
1299* The C library header files now use `extern "C"' when used by the C++
1300 compiler, so the C library should now work with C++ code.
1301
1302* The header file <bstring.h> is gone. <string.h> now declares bcopy,
56ddf355
UD
1303 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
1304 in <strings.h>.)
28f540f4
RM
1305
1306* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
1307 function which uses the `merge sort' algorithm, and is said to be
1308 significantly faster than the old GNU `qsort' function. Merge sort is
1309 now the standard `qsort' function. The new algorithm can require a lot
1310 of temporary storage; so, the old sorting function is called when the
1311 required storage is not available.
1312
1313* The C library now includes Michael Glad's Ultra Fast Crypt, which
1314 provides the Unix `crypt' function, plus some other entry points.
28f540f4
RM
1315
1316* The code and header files taken from 4.4 BSD have been updated with the
1317 latest files released from Berkeley.
