8 \f
9 Version 2.2.5
11 * Stephen Moshier implemented powl and cbrtl for the 128-bit
12 long double format.
14 * Masahide Washizawa contributed iconv modules for IBM1160 and IBM1161
15 charsets.
17 * Andreas Jaeger contributed a port to x86_64/Linux.
19 * libc functions using I/O streams now can handle wide-oriented streams
20 as well.
22 Version 2.2.4
24 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
25 asinh, atanh, j0 for the 128-bit long double format.
27 * Bruno Haible updated all the code handling Unicode in some form to
28 support Unicode 3.1.
30 * Speed of regex for single-byte locales is back to previous levels.
31 Patch by Isamu Hasegawa.
33 * Alpha, SPARC, and IA-64 now also using floating stacks.
35 * Startup time of internationalized applications greatly improved through
36 iconv cache. Use iconvconfig to generate the cache file.
37 Contributed by Ulrich Drepper.
39 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
40 severe performance problems. Patch by David Mosberger.
42 * The Hurd port got a lot more functionality like AIO, various stdio
43 extensions, etc. Mainly done by Roland McGrath.
45 * mtrace can now lookup symbols in shared libraries.
46 \f
47 Version 2.2.3
49 * Intel's IA-64 math library is largely integrated. It provides fast and
50 accurate implementatations for most basic and standard math functions
51 in float, double, and long double format.
53 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
54 and asin for the 96-bit long double format and asin, log, tan for the
55 128-bit long double format.
57 * The beginning of a last-bit accurate math library by IBM Haifa were added.
58 The basic double functions exist today. Contributed by Abraham Ziv
59 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
60 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
62 * An asynchronous name lookup library was added. The interface is designed
63 after POSIX AIO. The proposal was circulated beforehand to get comments.
64 No negative ones came in. Implemented by Ulrich Drepper.
66 * Port to S390/64bit contributed by Martin Schwidefsky
67 <schwidefsky@de.ibm.com>.
69 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
70 of functions for Linux/IA-64.
72 * The RPC code is now thread safe. Threads can now use the same service
73 of different services at the same time. Patch by Eric Norum
74 <eric.norum@usask.ca> with some help by Ulrich Drepper.
76 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
77 family of functions for Linux/S390.
79 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
80 of functions for Linux/x86.
82 * Port to Linux/CRIS contributed by Axis Communications.
83 \f
84 Version 2.2.2
86 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
87 we can now check for namespace violations and missing declarations. The
88 result is that almost all headers are now Unix-compliant (as defined in
89 the upcoming XPG6). The negative side is that some programs might need
90 corrections, too, if they depend on the incorrect form of the headers in
91 previous versions which defined too many symbols and included too many
92 other headers.
94 * regex now handles multibyte character sets correctly.
95 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
97 * iconv (the program) does now conform to the upcoming XPG6 and handles
98 charmaps. Instead of the charset names the path of charmaps can be
99 provided and the conversion happens based on this data.
100 Contributed by Ulrich Drepper.
102 * The locale program now provides detailed information about the installed
103 locales. While
105 locale -a
107 only lists the names of the supported locales
109 locale -a --verbose
111 provides details such as country, language, and codeset name.
112 Contributed by Ulrich Drepper.
113 \f
114 Version 2.2.1
116 * The gencat program now parses the input file according to the charset
117 selected by the LC_CTYPE category. This is important for stateful
118 character sets. To make generating catalogs easier there is a way
119 to overwrite the charset selected by the locale: before the first
120 message or $ quote line the catalog can contain a line like
122 $ codeset=ISO-8859-2
124 to select the charset (ISO-8859-2 in this case).
126 Implemented by Shinya Hanataka and Ulrich Drepper.
128 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
129 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
130 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
132 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
133 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
135 * The LANGUAGE environment variable is now ignored unless the locale is
136 changed from the default "C" locale.
138 * The usual bug fixes.
139 \f
140 Version 2.2
142 * Greg McGary added runtime support for bounds checking using gcc's
143 new -fbounded-pointers option. ix86 target is complete. PowerPC
144 is in progress.
146 * Thorsten Kukuk added secure mode support to nscd.
148 * The Berkeley db libraries have been removed.
150 Related, the nss_db module is now in a separate package since it
151 obviously requires a database library being available.
153 * Wide character I/O streams implemented by Ulrich Drepper.
155 * Functions from the extended socket API added by Ulrich Drepper.
157 * Functions feenableexcept and fedisableexcept to control the
158 behaviour of individual exceptions have been added by Andreas Jaeger.
160 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
162 * The resolver code has been updated from bind 8.2.3-T5B which supports
163 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
164 and Mark Kettenis.
166 This change could in some situations effect backward compatibility. Since
167 now `_res' is a thread-local instead of a global variable, modifying it
168 in one thread does not have any effect in other threads.
170 The resolver library was also extended to allow IPv6 as the transport
171 protocol for the requests. This work was done by Stig Venaas.
173 * Compatibility code for K&R C compilers has been removed from the
174 header files. A ISO C compiler is needed to use the library
175 (conforming to either C89 or C99 standard).
177 * Complete rewrite of the localedef program to support multibyte character
178 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
179 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
180 Implemented by Ulrich Drepper.
182 Bruno Haible significantly improved the generation and use of the data
183 structures for the wide character tables.
185 * Plural handling in gettext implemented by Ulrich Drepper.
187 * The utmp daemon has been removed.
189 * The port to MIPS-Linux has been finished by Andreas Jaeger.
191 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
192 and Yutaka Niibe.
194 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
196 * POSIX barriers implemented by Kaz Kylheku.
198 * POSIX spawn function family implemented by Ulrich Drepper.
200 * POSIX spinlocks are now available.
202 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
204 * the configure option --enable-kernel=X.Y.Z allows to strip out
205 compatibility for kernel versions before X.Y.Z. This is currently only
206 implemented for Linux.
208 * the sockaddr_in6 structure changed. The IPv6 working group added a new
209 field sin6_scope_id. This means that all programs using IPv6 should be
210 recompiled. Don't expect binary compatibility with previous glibc
211 versions.
213 * various conversion modules for IBM character sets contributed by
214 Masahide Washizawa.
216 * IA-64 port by Jes Sorensen and HJ Lu.

219 Compiling the GNU C Library for Linux/ia64
220 ******************************************
222 Please refer to the file INSTALL in the same directory as you found
223 this file for general information about configuring and compiling
224 glibc.
226 For general inquiries about glibc under Linux/ia64 please use the
227 following mailing list linux-ia64@linuxia64.org or one of the relevant
228 glibc mailing lists.
230 Recommended Tools for Compilation
231 =================================
233 In order for glibc-2.2 to build correctly on the ia64 you need at
234 least the following versions of the GNU tools (the :
236 * The Cygnus toolchain snapshot for the ia64 as of August 4
237 including the provided set of patches. It is however recommend
238 you use the October 24 toolchain snapshot or a more recent version.
240 OR alternatively you can try the following (the Cygnus toolchain is
241 the recommended solution):
243 * GCC and binutils, GAS and GNU LD out of CVS from
244 sources.redhat.com as of August 28, 2000 or later. The CVS tree
245 may require special patches to work properly on the ia64.
247 Configuring and compiling GNU Libc for Linux/ia64
248 =================================================
250 The library requires Linux kernel version 2.4.0-test4-000728 or
251 later to funtion properly. Besides that it support for debug libraries
252 is currently untested. Hence the following options
253 are required for configuring the library:
255 --disable-debug --enable-kernel=2.4.0
257 It is also important that you make sure the library picks up the
258 appropriate kernel header files, if you do not have recent enough
259 kernel headers in /usr/src/linux/include, you should use the
260 --with-headers=<path> option to specify the location.
262 As an example I personally use the following options to configure
263 the library:
265 --disable-debug
266 --disable-cvs
267 --enable-kernel=2.4.0
268 --host=ia64-linux
269 --enable-add-ons=yes
270 --prefix=/usr
271 --with-headers=/home/jes/linux/include
274 Good luck

278 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
279 \f
280 Version 2.1.3
282 * bug fixes
284 \f
285 Version 2.1.2
287 * bug fixes
289 \f
290 Version 2.1.1
292 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
294 * New xdr functions are added; some rpc functions are now 64bit clean.
296 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
298 * Fixed known incompatibilities with glibc 2.0.
300 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
302 * Optimized a number of functions (especially the ELF dynamic loader).
304 * Update timezone data files.
306 * lots of charmaps corrections
308 * some new locale definitions and charmaps
310 \f
311 Version 2.1
313 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
314 conform to POSIX member type requirements. Symbol versions have been
315 adjusted as needed within the library, and for direct use by applications,
316 but there is potential for problems if third-party libraries use
317 struct timeval as part of their interface. This does not present
318 a problem for X and other "essential" system libraries.
320 * An additional locale model to support C++ Standard Library locale
321 model and probably more was implemented by Ulrich Drepper.
323 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
324 symbol level.
326 * Miles Bader provided the `argp' function family to support hierachical
327 command line argument parsing, layered on top of getopt.
329 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
331 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
332 numbers.
334 * scanf recognizes the %a and %A format for scanning floating point numbers.
336 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
337 information and interfaces for the available integer types.
339 * about 130 new math functions were added to implement the ISO C9x math
340 library.
342 * the new header <complex.h> contains definitions of the complex math
343 functions from ISO C 9X.
345 * the new header <tgmath.h> defines generic macros to use complex or
346 real valued functions.
348 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
350 * Andreas Jaeger provided a test suite for the math library.
352 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
354 * Ulrich Drepper added character set conversion functions (iconv).
356 * Optimized string functions have been added.
358 * The localedata addon is now part of glibc.
360 * An implementation of profiling shared libraries was added by Ulrich Drepper.
362 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
363 daemon for NSS (nscd).
365 Missing a better place here are some numbers on improvements. Under
366 Linux 2.1.125 un-tar-ing the kernel sources takes
368 user system wall
370 using local files 12.19s 6.88s 22.91s
372 using NIS 13.92s 8.91s 26.34s
374 using NIS & nscd 10.37s 7.34s 25.30s
376 using NIS+ 27.57s 30.37s 640.46s
378 using NIS+ & nscd 10.25s 7.83s 26.51s
380 using NIS & old nscd [1] 13.83s 8.32s 29.60s
382 Keep in mind that non-namelookup related operations dominate above times.
383 It was just a common complain that using NIS+ unpacking the kernel is
384 horribly slow.
386 [1] The old nscd implementation is not available anymore since it was
387 distributed with glibc up to version 2.0.98 and thus is now replaced.
389 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
391 * Mark Kettenis provided a Hesiod NSS module.
393 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
394 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
396 * rcmd can now handle netgroups (Dick Streefland).
398 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
399 Bambrough.
401 * Support for the IPv6 protocol has been added to the socket API, as per the
402 latest draft standards.
404 * Support for Linux 2.2 has been added.
406 * Interface changes relative to the latest 2.0.x release:

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