40 Contributed by Ulrich Drepper.
41
42* The IA-64 specific part of ld.so was rewritten to eliminate some pretty
43 severe performance problems. Patch by David Mosberger.
44
45* The Hurd port got a lot more functionality like AIO, various stdio
46 extensions, etc. Mainly done by Roland McGrath.
129d706d
UD
47
48* mtrace can now lookup symbols in shared libraries.
33996419 49\f
2ace5721
UD
50Version 2.2.3
51
1746f2b0 52* Intel's IA-64 math library is largely integrated. It provides fast and
2ace5721
UD
53 accurate implementatations for most basic and standard math functions
54 in float, double, and long double format.
55
f128331c 56* Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
b8750342
UD
57 and asin for the 96-bit long double format and asin, log, tan for the
58 128-bit long double format.
07f951e4 59
e4d82761
UD
60* The beginning of a last-bit accurate math library by IBM Haifa were added.
61 The basic double functions exist today. Contributed by Abraham Ziv
62 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
63 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
64
2ace5721
UD
65* An asynchronous name lookup library was added. The interface is designed
66 after POSIX AIO. The proposal was circulated beforehand to get comments.
67 No negative ones came in. Implemented by Ulrich Drepper.
b8a8413c
UD
68
69* Port to S390/64bit contributed by Martin Schwidefsky
70 <schwidefsky@de.ibm.com>.
a66f0958
UD
71
72* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
73 of functions for Linux/IA-64.
481b550f
UD
74
75* The RPC code is now thread safe. Threads can now use the same service
76 of different services at the same time. Patch by Eric Norum
77 <eric.norum@usask.ca> with some help by Ulrich Drepper.
f128331c
UD
78
79* Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
80 family of functions for Linux/S390.
232fdf8c
UD
81
82* Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
83 of functions for Linux/x86.
eacde9d0
UD
84
85* Port to Linux/CRIS contributed by Axis Communications.
2ace5721 86\f
306eeae5
UD
87Version 2.2.2
88
464d97ec 89* Lots of headers were cleaned up. Using the tool in the conform/ subdir
306eeae5
UD
90 we can now check for namespace violations and missing declarations. The
91 result is that almost all headers are now Unix-compliant (as defined in
92 the upcoming XPG6). The negative side is that some programs might need
93 corrections, too, if they depend on the incorrect form of the headers in
94 previous versions which defined too many symbols and included too many
95 other headers.
464d97ec
UD
96
97* regex now handles multibyte character sets correctly.
98 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
99
100* iconv (the program) does now conform to the upcoming XPG6 and handles
101 charmaps. Instead of the charset names the path of charmaps can be
102 provided and the conversion happens based on this data.
103 Contributed by Ulrich Drepper.
104
105* The locale program now provides detailed information about the installed
106 locales. While
107
108 locale -a
109
110 only lists the names of the supported locales
111
112 locale -a --verbose
113
114 provides details such as country, language, and codeset name.
115 Contributed by Ulrich Drepper.
306eeae5 116\f
d2defdc4
UD
117Version 2.2.1
118
119* The gencat program now parses the input file according to the charset
120 selected by the LC_CTYPE category. This is important for stateful
121 character sets. To make generating catalogs easier there is a way
122 to overwrite the charset selected by the locale: before the first
123 message or $ quote line the catalog can contain a line like
124
125 $ codeset=ISO-8859-2
126
127 to select the charset (ISO-8859-2 in this case).
128
129 Implemented by Shinya Hanataka and Ulrich Drepper.
aea6353a
UD
130
131* New codeset conversion modules: IBM-922 (Estonia PC codeset),
132 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
133 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
234669e2
UD
134
135* Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
136 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
137
138* The LANGUAGE environment variable is now ignored unless the locale is
139 changed from the default "C" locale.
140
141* The usual bug fixes.
d2defdc4 142\f
2e92188d
UD
143Version 2.2
144
08a2e4a0
GM
145* Greg McGary added runtime support for bounds checking using gcc's
146 new -fbounded-pointers option. ix86 target is complete. PowerPC
147 is in progress.
148
2e92188d
UD
149* Thorsten Kukuk added secure mode support to nscd.
150
793bd4d9 151* The Berkeley db libraries have been removed.
2e92188d 152
47b853e8
UD
153 Related, the nss_db module is now in a separate package since it
154 obviously requires a database library being available.
155
0013b2b1
UD
156* Wide character I/O streams implemented by Ulrich Drepper.
157
abbffdf9 158* Functions from the extended socket API added by Ulrich Drepper.
01c771d0 159
6e8afc1c
UD
160* Functions feenableexcept and fedisableexcept to control the
161 behaviour of individual exceptions have been added by Andreas Jaeger.
162
591e1ffb
UD
163* ldconfig program added by Andreas Jaeger and Jakub Jelinek.
164
d3436b3c
UD
165* The resolver code has been updated from bind 8.2.3-T5B which supports
166 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
167 and Mark Kettenis.
2588068b
UD
168
169 This change could in some situations effect backward compatibility. Since
170 now `_res' is a thread-local instead of a global variable, modifying it
171 in one thread does not have any effect in other threads.
66ac0abe 172
a00c3ca9 173 The resolver library was also extended to allow IPv6 as the transport
d3436b3c
UD
174 protocol for the requests. This work was done by Stig Venaas.
175
1c5d4617
UD
176* Compatibility code for K&R C compilers has been removed from the
177 header files. A ISO C compiler is needed to use the library
178 (conforming to either C89 or C99 standard).
179
abbffdf9
UD
180* Complete rewrite of the localedef program to support multibyte character
181 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
182 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
183 Implemented by Ulrich Drepper.
184
8f3f1e09
UD
185 Bruno Haible significantly improved the generation and use of the data
186 structures for the wide character tables.
187
abbffdf9
UD
188* Plural handling in gettext implemented by Ulrich Drepper.
189
69173865
UD
190* The utmp daemon has been removed.
191
192* The port to MIPS-Linux has been finished by Andreas Jaeger.
193
37fb8add
UD
194* A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
195 and Yutaka Niibe.
196
594cee6c
UD
197* POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
198
40c4c9b5
UD
199* POSIX barriers implemented by Kaz Kylheku.
200
594cee6c
UD
201* POSIX spawn function family implemented by Ulrich Drepper.
202
203* POSIX spinlocks are now available.
204
40c4c9b5
UD
205* Timed wait functions for mutex, rwlock, and semaphores are implemented.
206
8f3f1e09
UD
207* the configure option --enable-kernel=X.Y.Z allows to strip out
208 compatibility for kernel versions before X.Y.Z. This is currently only
209 implemented for Linux.
210
3107c0c5
UD
211* the sockaddr_in6 structure changed. The IPv6 working group added a new
212 field sin6_scope_id. This means that all programs using IPv6 should be
213 recompiled. Don't expect binary compatibility with previous glibc
214 versions.
215
d2830ba4
UD
216* various conversion modules for IBM character sets contributed by
217 Masahide Washizawa.
218
8f3f1e09
UD
219* IA-64 port by Jes Sorensen and HJ Lu.

222Compiling the GNU C Library for Linux/ia64
223******************************************
224
225 Please refer to the file INSTALL in the same directory as you found
226this file for general information about configuring and compiling
227glibc.
228
229 For general inquiries about glibc under Linux/ia64 please use the
230following mailing list linux-ia64@linuxia64.org or one of the relevant
231glibc mailing lists.
232
233Recommended Tools for Compilation
234=================================
235
236 In order for glibc-2.2 to build correctly on the ia64 you need at
237least the following versions of the GNU tools (the :
238
239 * The Cygnus toolchain snapshot for the ia64 as of August 4
aea6353a
UD
240 including the provided set of patches. It is however recommend
241 you use the October 24 toolchain snapshot or a more recent version.
8f3f1e09
UD
242
243 OR alternatively you can try the following (the Cygnus toolchain is
244 the recommended solution):
245
246 * GCC and binutils, GAS and GNU LD out of CVS from
aea6353a 247 sources.redhat.com as of August 28, 2000 or later. The CVS tree
8f3f1e09
UD
248 may require special patches to work properly on the ia64.
249
250Configuring and compiling GNU Libc for Linux/ia64
251=================================================
252
253 The library requires Linux kernel version 2.4.0-test4-000728 or
aea6353a
UD
254later to funtion properly. Besides that it support for debug libraries
255is currently untested. Hence the following options
8f3f1e09
UD
256are required for configuring the library:
257
aea6353a 258 --disable-debug --enable-kernel=2.4.0
8f3f1e09
UD
259
260 It is also important that you make sure the library picks up the
261appropriate kernel header files, if you do not have recent enough
262kernel headers in /usr/src/linux/include, you should use the
263--with-headers=<path> option to specify the location.
264
265 As an example I personally use the following options to configure
266the library:
267
268 --disable-debug
8f3f1e09
UD
269 --disable-cvs
270 --enable-kernel=2.4.0
271 --host=ia64-linux
272 --enable-add-ons=yes
273 --prefix=/usr
274 --with-headers=/home/jes/linux/include
275
276
277Good luck

282\f
283Version 2.1.3
284
285* bug fixes

288Version 2.1.2
289
290* bug fixes

e518937a
UD
293Version 2.1.1
294
27995311
UD
295* New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
296
16b0f634
UD
297* New xdr functions are added; some rpc functions are now 64bit clean.
298
407d26b7 299* Fixed a number of bugs and memory leaks (especially in NIS+ code).
16b0f634
UD
300
301* Fixed known incompatibilities with glibc 2.0.
302
407d26b7 303* New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
16b0f634 304
407d26b7 305* Optimized a number of functions (especially the ELF dynamic loader).
16b0f634
UD
306
307* Update timezone data files.
27995311 308
554b8800
UD
309* lots of charmaps corrections
310
311* some new locale definitions and charmaps
312
e518937a 313\f
c84142e8
UD
314Version 2.1
315
da2d1bc5
UD
316* Richard Henderson corrected size of struct timeval on Linux/Alpha to
317 conform to POSIX member type requirements. Symbol versions have been
318 adjusted as needed within the library, and for direct use by applications,
319 but there is potential for problems if third-party libraries use
320 struct timeval as part of their interface. This does not present
321 a problem for X and other "essential" system libraries.
322
c84142e8 323* An additional locale model to support C++ Standard Library locale
1fb05e3d 324 model and probably more was implemented by Ulrich Drepper.
c84142e8 325
1fb05e3d 326* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
c84142e8
UD
327 symbol level.
328
329* Miles Bader provided the `argp' function family to support hierachical
330 command line argument parsing, layered on top of getopt.
377a515b 331
cbdee279 332* strtod accepts new hexadecimal floating-point format from ISO C 9X.
377a515b
UD
333
334* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
cbdee279 335 numbers.
377a515b 336
cbdee279 337* scanf recognizes the %a and %A format for scanning floating point numbers.
e61abf83 338
48869012
UD
339* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
340 information and interfaces for the available integer types.
e61abf83 341
813f4f4d
UD
342* about 130 new math functions were added to implement the ISO C9x math
343 library.
344
e61abf83 345* the new header <complex.h> contains definitions of the complex math
cbdee279
UD
346 functions from ISO C 9X.
347
348* the new header <tgmath.h> defines generic macros to use complex or
349 real valued functions.
e61abf83 350
a5a0310d 351* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
e61abf83 352
a5a0310d
UD
353* Andreas Jaeger provided a test suite for the math library.
354
355* Mark Kettenis implemented the utmpx interface and an utmp daemon.
cbdee279 356
440d13e2 357* Ulrich Drepper added character set conversion functions (iconv).
cbdee279
UD
358
359* Optimized string functions have been added.
360
361* The localedata addon is now part of glibc.
2eb45444
UD
362
363* An implementation of profiling shared libraries was added by Ulrich Drepper.
ea278354 364
48244d09
UD
365* Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
366 daemon for NSS (nscd).
367
368 Missing a better place here are some numbers on improvements. Under
369 Linux 2.1.125 un-tar-ing the kernel sources takes

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

40a4b79f 789Version 2.0
28f540f4 790
d3669add
RM
791* GNU extensions are no longer declared by default. To enable them you
792 must define the macro `_GNU_SOURCE' in your program or compile with
793 `-D_GNU_SOURCE'.
794
28f540f4
RM
795* The library has changed from using GNU ld symbol aliases to using weak
796 symbols where available. The ELF object file format supports weak
797 symbols; GNU ld also supports weak symbols in the a.out format. (There
798 is also now support for other GNU ld extensions in ELF. Use the
787126fe
RM
799 `--with-elf' option to configure to indicate you have ELF, and
800 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
28f540f4
RM
801 of many files which contained only symbol aliases, reducing the size of
802 the source and the compiled library; many other files were renamed to
803 less cryptic names previously occupied by the symbol alias files.
dcf0671d
UD
804 There is a new header file <elf.h> for programs which operate on
805 files in the ELF format.
49e522bf
RM
806
807* Converted to Autoconf version 2, so `configure' has more options.
808 Run `configure --help' to see the details.
809
810* The library can now be configured to build profiling, highly-optimized
b25c5d66
RM
811 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
812 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
813 `configure' enable building these extra libraries. The shared library is
814 built by default when using both ELF and GNU ld. When shared libraries
815 are enabled, the new library `-ldl' is available for arbitrary run-time
816 loading of shared objects; its interface is defined in <dlfcn.h>. The
817 new header file <link.h> gives access to the internals of the run-time
33a934a3
UD
818 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
819 application of same name on other systems and it provides information
820 about dynamically linked binaries.
49e522bf 821
71733723
RM
822* The C library now provides the run-time support code for profiling
823 executables compiled with `-pg'. Programs can control the profiling code
d3669add
RM
824 through the interface in <sys/gmon.h>. The `gmon.out' files written by
825 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
826 the support for this file format was contributed by David Mosberger-Tang.
71733723 827
f7eac6eb 828* The math code has been replaced with a math library based on fdlibm from
33a934a3
UD
829 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
830 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
831 functions. The math functions now reside in a separate library, so
832 programs using them will need to use `-lm' their linking commands.
833
834* John C. Bowman contributed optimized ix87 assembler inline functions.
f7eac6eb 835
5f0e6fc7
RM
836* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
837 mechanism similar to that found in Solaris 2. This is now used for the
33a934a3
UD
838 group, passwd, hosts, networks, services, protocols, rpc, ethers,
839 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
840 file controls what services are used for each individual database. This
841 works by loading shared libraries with names specified in `nsswitch.conf',
842 so service modules can be changed or added at any time without even
843 relinking any program. Currently there are the file, db, and NIS based
844 NSS services available.
5f0e6fc7 845
49e522bf
RM
846* The new functions `strtoq' and `strtouq' parse integer values from
847 strings, like `strtol' and `strtoul', but they return `long long int' and
848 `unsigned long long int' values, respectively (64-bit quantities).
849
850* The new functions `strtof' and `strtold' parse floating-point values from
851 strings, like `strtod', but they return `float' and `long double' values,
852 respectively (on some machines `double' and `long double' are the same).
853
854* Ulrich Drepper has contributed new implementations of the floating-point
855 printing and reading code used in the `printf' family of functions and
856 `strtod', `strtof', and `strtold'. These new functions are perfectly
857 accurate, and much faster than the old ones.
858
33a934a3
UD
859* The implementation of the POSIX locale model was completely rewritten by
860 Ulrich Drepper. This includes the new programs `localedef' and `locale'
861 to compile the POSIX locale definition.
862
863* The former dummy implementations of the strcoll and strxfrm function are
864 now replaced by fully functional code contributed by Ulrich Drepper. The
865 collation information comes from the POSIX locale definitions.
866
49e522bf
RM
867* The new header <langinfo.h> defines an interface for accessing
868 various locale-dependent data (using the locale chosen with `setlocale').
869
f7eac6eb 870* Ulrich Drepper has contributed a new suite of functions for operation on
33a934a3 871 wide-character and multibyte-character strings, in <wchar.h>;
b7407d63 872 and classification and case conversion of wide characters, in <wctype.h>.
33a934a3
UD
873 These new functions are conforming to the ISO C, Amendement 1 specification.
874
875* There is now a second implementation of the standard I/O library available.
876 It comes from GNU libg++ as was written by Per Bothner, heavily modified
877 by Hongjiu Lu and made thread safe by Ulrich Drepper.
f7eac6eb 878
71733723 879* You can now use positional parameter specifications in format strings
49e522bf
RM
880 for the `printf' and `scanf' families of functions. For example,
881 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
882 ``Number 6, Mr Jones''. This is mainly useful when providing different
d365fd2c
RM
883 format strings for different languages, whose grammars may dictate
884 different orderings of the values being printed. To support this
49e522bf 885 feature, the interface for `register_printf_handler' has changed; see
d365fd2c 886 the header file <printf.h> for details.
49e522bf
RM
887
888* The `printf' and `scanf' families of functions now understand a new
889 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
890 to group numbers as indicated by the locale; for `scanf' and friends, this
891 says to accept as valid only a number with all the proper grouping
892 separators in the right places. In the default "C" locale, numbers are
893 not grouped; but locales for specific countries will define the usual
894 conventions (i.e. separate thousands with `,' in the US locale).
28f540f4
RM
895
896* The pgrp functions have been regularized, slightly incompatibly but much
897 less confusingly. The core functions are now `getpgid' and `setpgid',
898 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
899 argument) and BSD `setpgrp' (identical to `setpgid') functions are
900 provided for compatibility. There is no longer an incompatible `getpgrp'
901 with an argument declared under _BSD_SOURCE; no BSD code uses it.
902
903* The new header file <fts.h> and suite of functions simplify programs that
904 operate on directory trees. This code comes from 4.4 BSD.
905
33a934a3
UD
906* The resolver code has been updated from the BIND 4.9.5-P1 release.
907 Parts of the code were heavily modified by Ulrich Drepper to fit in the
908 NSS scheme used in glibc.
28f540f4 909
28f540f4
RM
910* There is a new malloc debugging hook `__memalign_hook'.
911
912* There are new typedefs `ushort' for `unsigned short int' and `uint' for
913 `unsigned int' in <sys/types.h>. These are for compatibility only and
914 their use is discouraged.
915
916* The `-lmcheck' library to enable standard malloc debugging hooks is now
917 done differently, so that it works even without GNU ld.
787126fe 918
22a1292a
RM
919* New function `euidaccess' checks allowed access to a file like `access',
920 but using the effective IDs instead of the real IDs.
49e522bf
RM
921
922* The time zone data files have been updated for the latest and greatest
923 local time conventions of the countries of the world.
924
925* The new function `dirfd' extracts the file descriptor used by a DIR stream;
926 see <dirent.h>.
927
928* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
929 for formatting floating-point numbers. They are provided only for
33a934a3

930 compatibility; new programs should use `sprintf' instead. There are
931 also equivalent function for the `long double' floating-point type and
932 all functions also exist in a reentrant form.
342414a6
RM
933
934* The new auxiliary library `-lutil' from 4.4 BSD contains various
935 functions for maintaining the login-record files (primarily of use to
936 system programs such as `login'), and convenient functions for
937 allocating and initializing a pseudo-terminal (pty) device.
c709e372
RM
938
939* Ulrich Drepper has contributed new support for System V style
940 shared memory and IPC on systems that support it.
941
942* Ulrich Drepper has contributed several miscellaneous new functions found
943 in System V: The `hsearch' family of functions provide an effective
944 implementation of hash tables; `a64l' and `l64a' provide a very simple
945 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
946 number generator.
947
948* Ulrich Drepper has contributed new reentrant counterparts for the
949 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
950
951* Ulrich Drepper has contributed new, highly-optimized versions of several
952 string functions for the i486/Pentium family of processors.
953
71733723 954* Ulrich Drepper has updated the Linux-specific code, based largely
c709e372 955 on work done in Hongjiu Lu's version of GNU libc for Linux.
33a934a3
UD
956 The GNU library now supports Linux versions 2.0.10 and later,
957 using the ELF object file format (i[3456]86-*-linux).
c709e372 958
d3669add
RM
959* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
960
33a934a3
UD
961* David Mosberger-Tang and Richard Henderson have ported the C library
962 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
963 dynamic linking support for ELF/Alpha.
964
965* Richard Henderson contributed several Alpha optimized assembler function
966 for arithmetic and string handling.
d3669add 967
c709e372 968* Ulrich Drepper has contributed a new set of message catalog functions to
40a4b79f
RM
969 support multiple languages using the <libintl.h> interface, for use with
970 his new package GNU gettext. Translation volunteers have contributed
971 catalogs of the library's messages in Spanish, German, and Korean.
972
973* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
974 program and the `catgets' function for reading the catalog files it
975 creates. (The <libintl.h> interface is preferred; we include the
976 <nl_types.h> interface using `catgets' only for source compatibility with
977 programs already written to use it.)
71733723
RM
978
979* New header file <values.h> gives SVID-compatible names for <limits.h>
980 constants.
981
982* Various new macros, declarations, and small header files for compatibility
983 with 4.4 BSD.
984
985* New function `group_member' is a convenient way to check if a process has
986 a given effective group ID.
987
988* When using GCC 2.7 and later, the socket functions are now declared in a
989 special way so that passing an argument of type `struct sockaddr_in *',
990 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
991 `struct sockaddr *' type, does not generate a type-clash warning.
992
993* New function `error' declared in header file <error.h> is a convenient
6d52618b 994 function for printing error messages and optionally exiting; this is the
71733723
RM
995 canonical function used in GNU programs. The new functions `err', `warn',
996 and friends in header file <err.h> are the canonical 4.4 BSD interface for
997 doing the same thing.
998
999* The <glob.h> interface has several new flags from 4.4 BSD that extend the
1000 POSIX.2 `glob' function to do ~ and {...} expansion.
1001
1002* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
33a934a3 1003 `clearenv' which is used in POSIX.9 is also available.
71733723
RM
1004
1005* New function `getsid' returns session ID number on systems that support it.
1006
f7eac6eb
RM
1007* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1008 files <db.h> and <mpool.h> provide a rich set of functions for several
1009 types of simple databases stored in memory and in files, and <ndbm.h> is
6d52618b 1010 an old `ndbm'-compatible interface using the `db' functions. Link with
999493cb 1011 `-ldb' to get these functions.
f7eac6eb
RM
1012
1013* New macro `strdupa' copies a string like `strdup', but uses local stack
1014 space from `alloca' instead of dynamic heap space from `malloc'.
52e9a9d1
RM
1015
1016* New function `strnlen' is like `strlen' but searches only a given maximum
33a934a3
UD
1017 number of characters for the null terminator. `stpncpy', `strndup' and
1018 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1019 function.
40a4b79f
RM
1020
1021* New function `statfs' in header <sys/statfs.h>.
1022
1023* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1024 provide convenient functions for operating on blocks of null-terminated
1025 strings.
1026
1027* A new suite of functions in <utmp.h> handle all the details of reading
1028 and writing the utmp file.
33a934a3
UD
1029
1030* An implementation of the NIS/YP(tm) based NSS service was contributed by
1031 Thorsten Kukuk.
1032
1033* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1034 completely POSIX compliant and also implemented the extended functionality
1035 to handle alternate digit representation and alternate era date formats.
1036
1037* Ulrich Drepper provided an implementation of the `strptime' function
1038 defined in XPG4.2 which transforms a string into a `struct tm' value.
1039
1040* Paul Eggert provided the tzselect shell script as part of the timezone
1041 code. The shell script makes it easy to select the correct timezone
1042 specification.
1043
1044* The implementation of the malloc family of functions is completely replaced
1045 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1046 The implementation uses the mmap function (if available) and it is
1047 optimized for the use in multi threaded programs.
1048
1049* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1050 functions. This new functionality is usable by specifying a special
1051 salt string and it is compatible with implementation on *BSD systems.
1052
1053* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1054 `getsubopt' to handle second level command line options, `bsd_signal'
1055 to access BSD style `signal' functionality, the obsolete `regexp' style
1056 expression matcher.
1057
1058* the `lchown' function is available on system which support this
1059 functionality.
1060
1061* The implementation of the shadow password handling function was contributed
1062 by Ulrich Drepper.
1063
1064* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1065
1066* POSIX.1g support was added. The <sys/select.h> header is available,
1067 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1068 implementation of `getaddrinfo'.
28f540f4
RM
1069\f
1070Version 1.09
1071
1072* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
1073
1074* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
1075 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
1076
1077* The new function `daemon' from 4.4 BSD is useful for server programs that
1078 want to put themselves in the background.
1079
1080* Joel Sherrill has contributed support for several standalone boards that
1081 run without an operating system.
1082
1083* `printf', `scanf' and friends now accept a `q' type modifier for long
1084 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
1085
1086* All of the code taken from BSD (notably most of the math and networking
1087 routines) has been updated from the BSD 4.4-Lite release.
1088
1089* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
1090
1091* The new functions `getdomainname' and `setdomainname' fetch or change the
1092 YP/NIS domain name. These are system calls which exist on systems which
1093 have YP (aka NIS).
1094
1095* The time zone data files have been updated for the latest international
1096 conventions.
1097
1098* The SunRPC programs `portmap' and `rpcinfo' are now installed in
1099 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
1100\f
1101Version 1.08
1102
1103* The C library now includes support for Sun RPC, from Sun's free
1104 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
1105 are included. (There is still no support for YP.)
1106
1107* Tom Quinn has contributed a port of the C library to SGI machines running
1108 Irix 4 (mips-sgi-irix4).
1109
1110* The new `lockf' function is a simplified interface to the locking
1111 facilities of `fcntl', included for compatibility.
1112
1113* New time functions `timegm', `timelocal', and `dysize' for compatibility.
1114
1115* New header file <sys/timeb.h> and new function `ftime' for compatibility.
1116
1117* New header files <poll.h> and <sys/poll.h> and new function `poll' for
1118 compatibility.
1119
1120* The error message printed by `assert' for a failed assertion now includes
1121 the name of the program (if using GNU ld) and the name of the calling
1122 function (with versions of GCC that support this).
1123
1124* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
1125
1126* The library now includes the <sys/mman.h> header file and memory
1127 management functions `mmap', `munmap', `mprotect', `msync', and
1128 `madvise', on systems that support those facilities.
1129
1130* The interface for `mcheck' has changed slightly: the function called to
1131 abort the program when an allocation inconsistency is detected now takes
1132 an argument that indicates the type of failure. The new function
1133 `mprobe' lets you request a consistency check for a particular block at
1134 any time (checks are normally done only when you call `free' or `realloc'
1135 on a block).
1136
1137* It is now possible to easily cross-compile the C library, building on one
1138 system a library to run on another machine and/or operating system. All
1139 you need to do is set the variable `HOST_CC' in `configparms' to the
1140 native compiler for programs to run on the machine you are building on (a
1141 few generator programs are used on Unix systems); set `CC' to the
1142 cross-compiler.
1143
1144* The new function `fexecve' (only implemented on the GNU system) executes
1145 a program file given a file descriptor already open on the file.
1146\f
1147Version 1.07
1148
1149* Brendan Kehoe has contributed most of a port to the DEC Alpha
1150 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
1151
1152* You can set the variable `libprefix' in `configparms' to specify a prefix
1153 to be prepended to installed library files; this makes it easy to install
1154 the GNU C library to be linked as `-lgnuc' or whatever.
1155
1156* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
1157 copies a limited number of characters from a string, and returns the
1158 address of the last character written.
1159
1160* You no longer need to check for whether the installed `stddef.h' is
1161 compatible with the GNU C library. configure now checks for you.
1162
1163* You can now define a per-stream `fileno' function to convert the
1164 stream's cookie into an integral file descriptor.
1165
1166* ``malloc (0)'' no longer returns a null pointer. Instead, it
1167 allocates zero bytes of storage, and returns a unique pointer which
1168 you can pass to `realloc' or `free'. The behavior is undefined if
1169 you dereference this pointer.
1170
1171* The C library now runs on Sony NEWS m68k machines running either
1172 NewsOS 3 or NewsOS 4.
1173
1174* The new `syscall' function is a system-dependent primitive function
1175 for invoking system calls. It has the canonical behavior on Unix
1176 systems, including unreliable return values for some calls (such as
1177 `pipe', `fork' and `getppid').
1178
1179* The error code `EWOULDBLOCK' is now obsolete; it is always defined
1180 to `EAGAIN', which is the preferred name. On systems whose kernels
1181 use two distinct codes, the C library now translates EWOULDBLOCK to
1182 EAGAIN in every system call function.
1183\f
1184Version 1.06
1185
1186* The GNU C Library Reference Manual is now distributed with the library.
1187 `make dvi' will produce a DVI file of the printed manual.
1188 `make info' will produce Info files that you can read on line using C-h i
1189 in Emacs or the `info' program.
ea278354 1190 Please send comments on the manual to bug-glibc-manual@gnu.org.
28f540f4
RM
1191
1192* The library now supports SVR4 on i386s (i386-unknown-sysv4).
1193
1194* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
1195
1196* Jason Merrill has contributed a port to the Sequent Symmetry running
1197 Dynix version 3 (i386-sequent-dynix).
1198
1199* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
1200 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
1201
1202* New function `memory_warnings' lets you arrange to get warnings when
1203 malloc is running out of memory to allocate, like Emacs gives you.
1204
1205* The C library now contains the relocating allocator used in Emacs 19 for
1206 its editing buffers. This allocator (ralloc) minimizes allocation
1207 overhead and fragmentation by moving allocated regions around whenever it
1208 needs to. You always refer to a ralloc'd region with a "handle" (a
1209 pointer to a pointer--an object of type `void **').
1210
1211* There is a new `printf' format: `%m' gives you the string corresponding
1212 to the error code in `errno'.
1213
1214* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
1215 or `%[' conversion, but instead of filling in a fixed-sized buffer you
1216 pass, the `a' modifier says to fill in a `char **' you pass with a
1217 malloc'd string.
1218
1219* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
1220 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
1221 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
1222
1223* `mkstemp' is a traditional Unix function to atomically create and open a
1224 uniquely-named temporary file.
1225\f
1226Version 1.05
1227
1228* The standard location for the file that says what the local timezone is
1229 has changed again. It is now `/usr/local/etc/localtime' (or more
1230 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
1231
1232* The distribution no longer contains any files with names longer than 14
1233 characters.
1234
1235* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
1236 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
1237
1238* New functions `ttyslot' and `syslog' from 4.4 BSD.
1239\f
1240Version 1.04
1241
1242* The configuration process has changed quite a bit. The `configure'
1243 script is now used just like the configuration scripts for other GNU
1244 packages. The `sysdeps' directory hierarchy is much rearranged.
1245 The file `INSTALL' explains the new scheme in detail.
1246
1247* The header files no longer need to be processed into ANSI C and
1248 traditional C versions. There is just one set of files to install, and
1249 it will work with ANSI or old C compilers (including `gcc -traditional').
1250
1251* Brendan Kehoe and Ian Lance Taylor have ported the library to the
1252 MIPS DECStation running Ultrix 4.
1253
1254* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
1255 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
1256 made itself into a shared library.
1257
1258* Yet further improved support for the i386, running 4.3 BSD-like systems
1259 (such as Mach 3 with the Unix single-server), or System V.
1260
1261* New function `strncasecmp' to do case-insensitive string comparison
1262 with limited length.
1263
1264* New function `strsep' is a reentrant alternative to `strtok'.
1265
1266* New functions `scandir' and `alphasort' for searching directories.
1267
1268* New function `setenv' is a better interface to `putenv'.
1269
1270* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
1271 function for traversing a directory tree.
1272
1273* The GNU obstack package is now also part of the C library.
1274 The new function `open_obstack_stream' creates a stdio stream that
1275 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
1276 formatted output directly to an obstack.
1277
1278* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
1279 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
1280
1281* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
1282
1283* The new functions `strfry' and `memfrob' do mysterious and wonderful
1284 things to your strings.
1285
1286* There are some new test programs: test-fseek, testmb, and testrand.
1287
1288* Some work has been done to begin porting the library to 4.4 BSD and Linux.
1289 These ports are not finished, but are a good starting place for really
1290 supporting those systems.
1291
1292* `/etc/localtime' is now the standard location for the file that says what
1293 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
1294 This follows the general principle that `/etc' is the place for all local
1295 configuration files.
1296
1297* The C library header files now use `extern "C"' when used by the C++
1298 compiler, so the C library should now work with C++ code.
1299
1300* The header file <bstring.h> is gone. <string.h> now declares bcopy,
56ddf355
UD
1301 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
1302 in <strings.h>.)
28f540f4
RM
1303
1304* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
1305 function which uses the `merge sort' algorithm, and is said to be
1306 significantly faster than the old GNU `qsort' function. Merge sort is
1307 now the standard `qsort' function. The new algorithm can require a lot
1308 of temporary storage; so, the old sorting function is called when the
1309 required storage is not available.
1310
1311* The C library now includes Michael Glad's Ultra Fast Crypt, which
1312 provides the Unix `crypt' function, plus some other entry points.
28f540f4
RM
1313
1314* The code and header files taken from 4.4 BSD have been updated with the
1315 latest files released from Berkeley.
