UD
Ulrich Drepper2004-08-06 05:04:49 +0000458Version 2.3.4
459
460* Support for RFC 3678. Real implementations exist only for Linux so far.
461 Implemented by Ulrich Drepper.

Ulrich Drepper2004-09-17 08:44:34 +0000462
463* nscd can now cache entries persistently. Expiring entries are reloaded.
464 For speedups the cache can be shared in memory with client processes.
465 Implemented by Ulrich Drepper.
466
467* nscd can now perform SELinux checks.
468 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
469
0325dd20 Ulrich Drepper2004-10-19 16:05:21 +0000470* getaddrinfo queries are now cached. Canonical name lookup is performed
8a1f658b
UD
Ulrich Drepper2004-09-17 08:44:34 +0000471 efficiently.
472 Implemented by Ulrich Drepper.
473
474* The nothrow function attribute is used when headers are used by gcc when
475 compiling C code. This can avoid significant amounts of exception
476 handling data.
477
478* The malloc functions perform more error checking and are stricter when
479 it comes to reacting on errors. The default action is to terminate
0325dd20 Ulrich Drepper2004-10-19 16:05:21 +0000480 the process after showing an error message. Implemented by Ulrich Drepper.

482* Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
0325dd20
UD
Ulrich Drepper2004-10-19 16:05:21 +0000483 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
484
485* Namespaces in ld.so are implemented. DSOs can be loaded in separate
486 namespaces using the new function dlmopen(). This feature is of course,
487 like most other dynamic loading functionality, not available in statically
488 linked applications. Implemented by Ulrich Drepper.
489
490* Low-overhead boundary checking variants of string and some stdio functions
491 were added. These are to be used in conjunction with a gcc patch by
492 Jakub Jelinek which adds calls to these functions if possible.

RM
Roland McGrath2004-12-19 09:41:58 +0000493 Implemented by Jakub Jelinek and Ulrich Drepper.
494
495* Old code for several operating systems and machine architectures that
496 have not been in working condition in a long time have been removed from
497 the main source tree maintained by the GNU C Library's maintainers.
498 These files are now reside in the separate `ports' source module
499 that is usable as an add-on when building the library.

525
f87277f2
RM
Roland McGrath2002-12-03 00:54:55 +0000526* Thread-safe interfaces for many functions that access locale data
527 were added in version 2.3, but these features were omitted from NEWS.
528 Many functions have variants with an `_l' suffix that take a `locale_t'
529 object as a parameter rather than consulting the current locale.
530 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
531 create and maintain `locale_t' objects. Additionally, the new function
532 `uselocale' sets "the current locale" (as used by functions not so
533 parameterized) set for an individual thread. These features were added
534 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
535
747bf98e
RM
Roland McGrath2002-10-14 01:03:16 +0000536* The functions getresuid, getresgid, setresuid, and setresgid, which
537 have long been available on Linux, are now declared in <unistd.h>
538 and are now also available on the Hurd.
539
540* ELF thread-local storage support (TLS) now works on x86-64.

RM
Roland McGrath2002-12-03 00:54:55 +0000550* The `btowc' function should work at least twice as fast due to
551 specialized callbacks in the iconv modules. Implemented by Bruno Haible.

UD
Ulrich Drepper2003-01-13 09:28:02 +0000552
553* With approriate thread add-ons cancelable functions are now implemented
554 in libc.so as well. No need to call the function in libpthread. This
555 change allowed to finally disable the incorrect and expensive handling
556 of weak definition in ld.so.
557
558* Yet more PLT entries in libc.so have been removed. We finally arrived
559 at the bare minimum. Startup times improved appropriately.
560
561* Support for the new Linux/x86 system call interface was added. The
562 AT_SYSINFO auxiliary vector entry is recognized and handled.

306eeae5
UD
Ulrich Drepper2001-01-31 07:42:03 +0000707 we can now check for namespace violations and missing declarations. The
708 result is that almost all headers are now Unix-compliant (as defined in
709 the upcoming XPG6). The negative side is that some programs might need
710 corrections, too, if they depend on the incorrect form of the headers in
711 previous versions which defined too many symbols and included too many
712 other headers.

Ulrich Drepper2001-02-10 07:33:38 +0000713
714* regex now handles multibyte character sets correctly.
715 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
716
717* iconv (the program) does now conform to the upcoming XPG6 and handles
718 charmaps. Instead of the charset names the path of charmaps can be
719 provided and the conversion happens based on this data.
720 Contributed by Ulrich Drepper.
721
722* The locale program now provides detailed information about the installed
723 locales. While
724
725 locale -a
726
727 only lists the names of the supported locales
728
729 locale -a --verbose
730
731 provides details such as country, language, and codeset name.

735
736* The gencat program now parses the input file according to the charset
737 selected by the LC_CTYPE category. This is important for stateful
738 character sets. To make generating catalogs easier there is a way
739 to overwrite the charset selected by the locale: before the first
740 message or $ quote line the catalog can contain a line like
741
742 $ codeset=ISO-8859-2
743
744 to select the charset (ISO-8859-2 in this case).
745
746 Implemented by Shinya Hanataka and Ulrich Drepper.

786 This change could in some situations effect backward compatibility. Since
787 now `_res' is a thread-local instead of a global variable, modifying it
788 in one thread does not have any effect in other threads.

839Compiling the GNU C Library for Linux/ia64
840******************************************
841
842 Please refer to the file INSTALL in the same directory as you found
843this file for general information about configuring and compiling
844glibc.
845
846 For general inquiries about glibc under Linux/ia64 please use the
847following mailing list linux-ia64@linuxia64.org or one of the relevant
848glibc mailing lists.
849
850Recommended Tools for Compilation
851=================================
852
853 In order for glibc-2.2 to build correctly on the ia64 you need at
854least the following versions of the GNU tools (the :
855
856 * The Cygnus toolchain snapshot for the ia64 as of August 4
aea6353a
UD
Ulrich Drepper2000-11-28 18:12:18 +0000857 including the provided set of patches. It is however recommend
858 you use the October 24 toolchain snapshot or a more recent version.
8f3f1e09
UD
Ulrich Drepper2000-08-29 03:44:11 +0000859
860 OR alternatively you can try the following (the Cygnus toolchain is
861 the recommended solution):
862
863 * GCC and binutils, GAS and GNU LD out of CVS from
aea6353a Ulrich Drepper2000-11-28 18:12:18 +0000864 sources.redhat.com as of August 28, 2000 or later. The CVS tree
8f3f1e09
UD
Ulrich Drepper2000-08-29 03:44:11 +0000865 may require special patches to work properly on the ia64.
866
867Configuring and compiling GNU Libc for Linux/ia64
868=================================================
869
870 The library requires Linux kernel version 2.4.0-test4-000728 or
aea6353a
UD
Ulrich Drepper2000-11-28 18:12:18 +0000871later to funtion properly. Besides that it support for debug libraries
872is currently untested. Hence the following options
8f3f1e09
UD
Ulrich Drepper2000-08-29 03:44:11 +0000873are required for configuring the library:
874
aea6353a Ulrich Drepper2000-11-28 18:12:18 +0000875 --disable-debug --enable-kernel=2.4.0
8f3f1e09
UD
Ulrich Drepper2000-08-29 03:44:11 +0000876
877 It is also important that you make sure the library picks up the
878appropriate kernel header files, if you do not have recent enough
879kernel headers in /usr/src/linux/include, you should use the
880--with-headers=<path> option to specify the location.
881
882 As an example I personally use the following options to configure
883the library:
884
885 --disable-debug
8f3f1e09
UD
Ulrich Drepper2000-08-29 03:44:11 +0000886 --disable-cvs
887 --enable-kernel=2.4.0
888 --host=ia64-linux
889 --enable-add-ons=yes
890 --prefix=/usr
891 --with-headers=/home/jes/linux/include

UD
Ulrich Drepper1998-02-10 20:06:30 +0000933* Richard Henderson corrected size of struct timeval on Linux/Alpha to

935 adjusted as needed within the library, and for direct use by applications,
936 but there is potential for problems if third-party libraries use
937 struct timeval as part of their interface. This does not present
938 a problem for X and other "essential" system libraries.

Roland McGrath1996-03-19 21:59:41 +00001408* GNU extensions are no longer declared by default. To enable them you
1409 must define the macro `_GNU_SOURCE' in your program or compile with
1410 `-D_GNU_SOURCE'.
1411
28f540f4
RM
Roland McGrath1995-02-18 01:27:10 +00001412* The library has changed from using GNU ld symbol aliases to using weak
1413 symbols where available. The ELF object file format supports weak
1414 symbols; GNU ld also supports weak symbols in the a.out format. (There
1415 is also now support for other GNU ld extensions in ELF. Use the

RM
Roland McGrath1995-02-21 06:17:59 +00001416 `--with-elf' option to configure to indicate you have ELF, and
1417 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
28f540f4
RM
Roland McGrath1995-02-18 01:27:10 +00001418 of many files which contained only symbol aliases, reducing the size of
1419 the source and the compiled library; many other files were renamed to
1420 less cryptic names previously occupied by the symbol alias files.

UD
Ulrich Drepper1996-08-26 10:28:45 +00001421 There is a new header file <elf.h> for programs which operate on
1422 files in the ELF format.

RM
Roland McGrath1995-03-21 07:58:50 +00001423
1424* Converted to Autoconf version 2, so `configure' has more options.
1425 Run `configure --help' to see the details.
1426
1427* The library can now be configured to build profiling, highly-optimized

Roland McGrath1995-08-07 21:45:04 +00001428 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1429 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1430 `configure' enable building these extra libraries. The shared library is
1431 built by default when using both ELF and GNU ld. When shared libraries
1432 are enabled, the new library `-ldl' is available for arbitrary run-time
1433 loading of shared objects; its interface is defined in <dlfcn.h>. The
1434 new header file <link.h> gives access to the internals of the run-time
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001435 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1436 application of same name on other systems and it provides information
1437 about dynamically linked binaries.

71733723
RM
Roland McGrath1996-01-02 08:57:42 +00001439* The C library now provides the run-time support code for profiling
1440 executables compiled with `-pg'. Programs can control the profiling code
d3669add
RM
Roland McGrath1996-03-19 21:59:41 +00001441 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1442 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1443 the support for this file format was contributed by David Mosberger-Tang.
71733723 Roland McGrath1996-01-02 08:57:42 +00001444
f7eac6eb Roland McGrath1996-03-05 21:41:30 +00001445* The math code has been replaced with a math library based on fdlibm from
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001446 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1447 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1448 functions. The math functions now reside in a separate library, so
1449 programs using them will need to use `-lm' their linking commands.
1450
1451* John C. Bowman contributed optimized ix87 assembler inline functions.
f7eac6eb Roland McGrath1996-03-05 21:41:30 +00001452
5f0e6fc7
RM
Roland McGrath1996-06-25 08:56:57 +00001453* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1454 mechanism similar to that found in Solaris 2. This is now used for the
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001455 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1456 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1457 file controls what services are used for each individual database. This
1458 works by loading shared libraries with names specified in `nsswitch.conf',
1459 so service modules can be changed or added at any time without even
1460 relinking any program. Currently there are the file, db, and NIS based
1461 NSS services available.

49e522bf
RM
Roland McGrath1995-03-21 07:58:50 +00001463* The new functions `strtoq' and `strtouq' parse integer values from
1464 strings, like `strtol' and `strtoul', but they return `long long int' and
1465 `unsigned long long int' values, respectively (64-bit quantities).
1466
1467* The new functions `strtof' and `strtold' parse floating-point values from
1468 strings, like `strtod', but they return `float' and `long double' values,
1469 respectively (on some machines `double' and `long double' are the same).
1470
1471* Ulrich Drepper has contributed new implementations of the floating-point
1472 printing and reading code used in the `printf' family of functions and
1473 `strtod', `strtof', and `strtold'. These new functions are perfectly
1474 accurate, and much faster than the old ones.
1475
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001476* The implementation of the POSIX locale model was completely rewritten by
1477 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1478 to compile the POSIX locale definition.
1479
1480* The former dummy implementations of the strcoll and strxfrm function are
1481 now replaced by fully functional code contributed by Ulrich Drepper. The
1482 collation information comes from the POSIX locale definitions.
1483
49e522bf
RM
Roland McGrath1995-03-21 07:58:50 +00001484* The new header <langinfo.h> defines an interface for accessing
1485 various locale-dependent data (using the locale chosen with `setlocale').
1486
f7eac6eb Roland McGrath1996-03-05 21:41:30 +00001487* Ulrich Drepper has contributed a new suite of functions for operation on
33a934a3 Ulrich Drepper1997-01-26 05:33:35 +00001488 wide-character and multibyte-character strings, in <wchar.h>;
b7407d63 Roland McGrath1996-03-29 01:04:20 +00001489 and classification and case conversion of wide characters, in <wctype.h>.
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001490 These new functions are conforming to the ISO C, Amendement 1 specification.
1491
1492* There is now a second implementation of the standard I/O library available.
1493 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1494 by Hongjiu Lu and made thread safe by Ulrich Drepper.
f7eac6eb Roland McGrath1996-03-05 21:41:30 +00001495
71733723 Roland McGrath1996-01-02 08:57:42 +00001496* You can now use positional parameter specifications in format strings
49e522bf
RM
Roland McGrath1995-03-21 07:58:50 +00001497 for the `printf' and `scanf' families of functions. For example,
1498 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1499 ``Number 6, Mr Jones''. This is mainly useful when providing different
d365fd2c
RM
Roland McGrath1995-03-24 07:59:23 +00001500 format strings for different languages, whose grammars may dictate
1501 different orderings of the values being printed. To support this
49e522bf Roland McGrath1995-03-21 07:58:50 +00001502 feature, the interface for `register_printf_handler' has changed; see
d365fd2c Roland McGrath1995-03-24 07:59:23 +00001503 the header file <printf.h> for details.
49e522bf
RM
Roland McGrath1995-03-21 07:58:50 +00001504
1505* The `printf' and `scanf' families of functions now understand a new
1506 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1507 to group numbers as indicated by the locale; for `scanf' and friends, this
1508 says to accept as valid only a number with all the proper grouping
1509 separators in the right places. In the default "C" locale, numbers are
1510 not grouped; but locales for specific countries will define the usual
1511 conventions (i.e. separate thousands with `,' in the US locale).
28f540f4
RM
Roland McGrath1995-02-18 01:27:10 +00001512
1513* The pgrp functions have been regularized, slightly incompatibly but much
1514 less confusingly. The core functions are now `getpgid' and `setpgid',
1515 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1516 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1517 provided for compatibility. There is no longer an incompatible `getpgrp'
1518 with an argument declared under _BSD_SOURCE; no BSD code uses it.
1519
1520* The new header file <fts.h> and suite of functions simplify programs that
1521 operate on directory trees. This code comes from 4.4 BSD.
1522
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001523* The resolver code has been updated from the BIND 4.9.5-P1 release.
1524 Parts of the code were heavily modified by Ulrich Drepper to fit in the
1525 NSS scheme used in glibc.

28f540f4
RM
Roland McGrath1995-02-18 01:27:10 +00001527* There is a new malloc debugging hook `__memalign_hook'.
1528
1529* There are new typedefs `ushort' for `unsigned short int' and `uint' for
1530 `unsigned int' in <sys/types.h>. These are for compatibility only and
1531 their use is discouraged.
1532
1533* The `-lmcheck' library to enable standard malloc debugging hooks is now
1534 done differently, so that it works even without GNU ld.

22a1292a
RM
Roland McGrath1995-02-25 01:23:32 +00001536* New function `euidaccess' checks allowed access to a file like `access',
1537 but using the effective IDs instead of the real IDs.
49e522bf
RM
Roland McGrath1995-03-21 07:58:50 +00001538
1539* The time zone data files have been updated for the latest and greatest
1540 local time conventions of the countries of the world.
1541
1542* The new function `dirfd' extracts the file descriptor used by a DIR stream;
1543 see <dirent.h>.
1544
1545* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
1546 for formatting floating-point numbers. They are provided only for
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001547 compatibility; new programs should use `sprintf' instead. There are
1548 also equivalent function for the `long double' floating-point type and
1549 all functions also exist in a reentrant form.
342414a6
RM
Roland McGrath1995-03-27 10:24:00 +00001550
1551* The new auxiliary library `-lutil' from 4.4 BSD contains various
1552 functions for maintaining the login-record files (primarily of use to
1553 system programs such as `login'), and convenient functions for
1554 allocating and initializing a pseudo-terminal (pty) device.
c709e372
RM
Roland McGrath1995-09-27 02:50:10 +00001555
1556* Ulrich Drepper has contributed new support for System V style
1557 shared memory and IPC on systems that support it.
1558
1559* Ulrich Drepper has contributed several miscellaneous new functions found
1560 in System V: The `hsearch' family of functions provide an effective
1561 implementation of hash tables; `a64l' and `l64a' provide a very simple
1562 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
1563 number generator.
1564
1565* Ulrich Drepper has contributed new reentrant counterparts for the
1566 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
1567
1568* Ulrich Drepper has contributed new, highly-optimized versions of several
1569 string functions for the i486/Pentium family of processors.
1570
71733723 Roland McGrath1996-01-02 08:57:42 +00001571* Ulrich Drepper has updated the Linux-specific code, based largely
c709e372 Roland McGrath1995-09-27 02:50:10 +00001572 on work done in Hongjiu Lu's version of GNU libc for Linux.
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001573 The GNU library now supports Linux versions 2.0.10 and later,
1574 using the ELF object file format (i[3456]86-*-linux).

RM
Roland McGrath1996-03-19 21:59:41 +00001576* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
1577
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001578* David Mosberger-Tang and Richard Henderson have ported the C library
1579 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
1580 dynamic linking support for ELF/Alpha.
1581
1582* Richard Henderson contributed several Alpha optimized assembler function
1583 for arithmetic and string handling.
d3669add Roland McGrath1996-03-19 21:59:41 +00001584
c709e372 Roland McGrath1995-09-27 02:50:10 +00001585* Ulrich Drepper has contributed a new set of message catalog functions to
40a4b79f
RM
Roland McGrath1996-06-22 21:14:17 +00001586 support multiple languages using the <libintl.h> interface, for use with
1587 his new package GNU gettext. Translation volunteers have contributed
1588 catalogs of the library's messages in Spanish, German, and Korean.
1589
1590* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
1591 program and the `catgets' function for reading the catalog files it
1592 creates. (The <libintl.h> interface is preferred; we include the
1593 <nl_types.h> interface using `catgets' only for source compatibility with
1594 programs already written to use it.)
71733723
RM
Roland McGrath1996-01-02 08:57:42 +00001595
1596* New header file <values.h> gives SVID-compatible names for <limits.h>
1597 constants.
1598
1599* Various new macros, declarations, and small header files for compatibility
1600 with 4.4 BSD.
1601
1602* New function `group_member' is a convenient way to check if a process has
1603 a given effective group ID.
1604
1605* When using GCC 2.7 and later, the socket functions are now declared in a
1606 special way so that passing an argument of type `struct sockaddr_in *',
1607 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
1608 `struct sockaddr *' type, does not generate a type-clash warning.
1609
1610* New function `error' declared in header file <error.h> is a convenient
6d52618b Ulrich Drepper1996-12-20 01:39:50 +00001611 function for printing error messages and optionally exiting; this is the
71733723
RM
Roland McGrath1996-01-02 08:57:42 +00001612 canonical function used in GNU programs. The new functions `err', `warn',
1613 and friends in header file <err.h> are the canonical 4.4 BSD interface for
1614 doing the same thing.
1615
1616* The <glob.h> interface has several new flags from 4.4 BSD that extend the
1617 POSIX.2 `glob' function to do ~ and {...} expansion.
1618
1619* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
33a934a3 Ulrich Drepper1997-01-26 05:33:35 +00001620 `clearenv' which is used in POSIX.9 is also available.
71733723
RM
Roland McGrath1996-01-02 08:57:42 +00001621
1622* New function `getsid' returns session ID number on systems that support it.
1623
f7eac6eb
RM
Roland McGrath1996-03-05 21:41:30 +00001624* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1625 files <db.h> and <mpool.h> provide a rich set of functions for several
1626 types of simple databases stored in memory and in files, and <ndbm.h> is
6d52618b Ulrich Drepper1996-12-20 01:39:50 +00001627 an old `ndbm'-compatible interface using the `db' functions. Link with
999493cb Roland McGrath1996-07-08 17:45:03 +00001628 `-ldb' to get these functions.
f7eac6eb
RM
Roland McGrath1996-03-05 21:41:30 +00001629
1630* New macro `strdupa' copies a string like `strdup', but uses local stack
1631 space from `alloca' instead of dynamic heap space from `malloc'.
52e9a9d1
RM
Roland McGrath1996-03-14 11:20:03 +00001632
1633* New function `strnlen' is like `strlen' but searches only a given maximum
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001634 number of characters for the null terminator. `stpncpy', `strndup' and
1635 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1636 function.
40a4b79f
RM
Roland McGrath1996-06-22 21:14:17 +00001637
1638* New function `statfs' in header <sys/statfs.h>.
1639
1640* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1641 provide convenient functions for operating on blocks of null-terminated
1642 strings.
1643
1644* A new suite of functions in <utmp.h> handle all the details of reading
1645 and writing the utmp file.
33a934a3
UD
Ulrich Drepper1997-01-26 05:33:35 +00001646
1647* An implementation of the NIS/YP(tm) based NSS service was contributed by
1648 Thorsten Kukuk.
1649
1650* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1651 completely POSIX compliant and also implemented the extended functionality
1652 to handle alternate digit representation and alternate era date formats.
1653
1654* Ulrich Drepper provided an implementation of the `strptime' function
1655 defined in XPG4.2 which transforms a string into a `struct tm' value.
1656
1657* Paul Eggert provided the tzselect shell script as part of the timezone
1658 code. The shell script makes it easy to select the correct timezone
1659 specification.
1660
1661* The implementation of the malloc family of functions is completely replaced
1662 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1663 The implementation uses the mmap function (if available) and it is
1664 optimized for the use in multi threaded programs.
1665
1666* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1667 functions. This new functionality is usable by specifying a special
1668 salt string and it is compatible with implementation on *BSD systems.
1669
1670* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1671 `getsubopt' to handle second level command line options, `bsd_signal'
1672 to access BSD style `signal' functionality, the obsolete `regexp' style
1673 expression matcher.
1674
1675* the `lchown' function is available on system which support this
1676 functionality.
1677
1678* The implementation of the shadow password handling function was contributed
1679 by Ulrich Drepper.
1680
1681* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1682
1683* POSIX.1g support was added. The <sys/select.h> header is available,
1684 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1685 implementation of `getaddrinfo'.

1687Version 1.09
1688
1689* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
1690
1691* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
1692 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
1693
1694* The new function `daemon' from 4.4 BSD is useful for server programs that
1695 want to put themselves in the background.
1696
1697* Joel Sherrill has contributed support for several standalone boards that
1698 run without an operating system.
1699
1700* `printf', `scanf' and friends now accept a `q' type modifier for long
1701 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
1702
1703* All of the code taken from BSD (notably most of the math and networking
1704 routines) has been updated from the BSD 4.4-Lite release.
1705
1706* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
1707
1708* The new functions `getdomainname' and `setdomainname' fetch or change the
1709 YP/NIS domain name. These are system calls which exist on systems which
1710 have YP (aka NIS).
1711
1712* The time zone data files have been updated for the latest international
1713 conventions.
1714
1715* The SunRPC programs `portmap' and `rpcinfo' are now installed in
1716 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
1717\f
1718Version 1.08
1719
1720* The C library now includes support for Sun RPC, from Sun's free
1721 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
1722 are included. (There is still no support for YP.)
1723
1724* Tom Quinn has contributed a port of the C library to SGI machines running
1725 Irix 4 (mips-sgi-irix4).
1726
1727* The new `lockf' function is a simplified interface to the locking
1728 facilities of `fcntl', included for compatibility.
1729
1730* New time functions `timegm', `timelocal', and `dysize' for compatibility.
1731
1732* New header file <sys/timeb.h> and new function `ftime' for compatibility.
1733
1734* New header files <poll.h> and <sys/poll.h> and new function `poll' for
1735 compatibility.
1736
1737* The error message printed by `assert' for a failed assertion now includes
1738 the name of the program (if using GNU ld) and the name of the calling
1739 function (with versions of GCC that support this).
1740
1741* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
1742
1743* The library now includes the <sys/mman.h> header file and memory
1744 management functions `mmap', `munmap', `mprotect', `msync', and
1745 `madvise', on systems that support those facilities.
1746
1747* The interface for `mcheck' has changed slightly: the function called to
1748 abort the program when an allocation inconsistency is detected now takes
1749 an argument that indicates the type of failure. The new function
1750 `mprobe' lets you request a consistency check for a particular block at
1751 any time (checks are normally done only when you call `free' or `realloc'
1752 on a block).
1753
1754* It is now possible to easily cross-compile the C library, building on one
1755 system a library to run on another machine and/or operating system. All
1756 you need to do is set the variable `HOST_CC' in `configparms' to the
1757 native compiler for programs to run on the machine you are building on (a
1758 few generator programs are used on Unix systems); set `CC' to the
1759 cross-compiler.
1760
1761* The new function `fexecve' (only implemented on the GNU system) executes
1762 a program file given a file descriptor already open on the file.
1763\f
1764Version 1.07
1765
1766* Brendan Kehoe has contributed most of a port to the DEC Alpha
1767 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
1768
1769* You can set the variable `libprefix' in `configparms' to specify a prefix
1770 to be prepended to installed library files; this makes it easy to install
1771 the GNU C library to be linked as `-lgnuc' or whatever.
1772
1773* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
1774 copies a limited number of characters from a string, and returns the
1775 address of the last character written.
1776
1777* You no longer need to check for whether the installed `stddef.h' is
1778 compatible with the GNU C library. configure now checks for you.
1779
1780* You can now define a per-stream `fileno' function to convert the
1781 stream's cookie into an integral file descriptor.
1782
1783* ``malloc (0)'' no longer returns a null pointer. Instead, it
1784 allocates zero bytes of storage, and returns a unique pointer which
1785 you can pass to `realloc' or `free'. The behavior is undefined if
1786 you dereference this pointer.
1787
1788* The C library now runs on Sony NEWS m68k machines running either
1789 NewsOS 3 or NewsOS 4.
1790
1791* The new `syscall' function is a system-dependent primitive function
1792 for invoking system calls. It has the canonical behavior on Unix
1793 systems, including unreliable return values for some calls (such as
1794 `pipe', `fork' and `getppid').
1795
1796* The error code `EWOULDBLOCK' is now obsolete; it is always defined
1797 to `EAGAIN', which is the preferred name. On systems whose kernels
1798 use two distinct codes, the C library now translates EWOULDBLOCK to
1799 EAGAIN in every system call function.
1800\f
1801Version 1.06
1802
1803* The GNU C Library Reference Manual is now distributed with the library.
1804 `make dvi' will produce a DVI file of the printed manual.
1805 `make info' will produce Info files that you can read on line using C-h i
1806 in Emacs or the `info' program.

Roland McGrath1995-02-18 01:27:10 +00001808
1809* The library now supports SVR4 on i386s (i386-unknown-sysv4).
1810
1811* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
1812
1813* Jason Merrill has contributed a port to the Sequent Symmetry running
1814 Dynix version 3 (i386-sequent-dynix).
1815
1816* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
1817 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
1818
1819* New function `memory_warnings' lets you arrange to get warnings when
1820 malloc is running out of memory to allocate, like Emacs gives you.
1821
1822* The C library now contains the relocating allocator used in Emacs 19 for
1823 its editing buffers. This allocator (ralloc) minimizes allocation
1824 overhead and fragmentation by moving allocated regions around whenever it
1825 needs to. You always refer to a ralloc'd region with a "handle" (a
1826 pointer to a pointer--an object of type `void **').
1827
1828* There is a new `printf' format: `%m' gives you the string corresponding
1829 to the error code in `errno'.
1830
1831* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
1832 or `%[' conversion, but instead of filling in a fixed-sized buffer you
1833 pass, the `a' modifier says to fill in a `char **' you pass with a
1834 malloc'd string.
1835
1836* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
1837 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
1838 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
1839
1840* `mkstemp' is a traditional Unix function to atomically create and open a
1841 uniquely-named temporary file.
1842\f
1843Version 1.05
1844
1845* The standard location for the file that says what the local timezone is
1846 has changed again. It is now `/usr/local/etc/localtime' (or more
1847 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
1848
1849* The distribution no longer contains any files with names longer than 14
1850 characters.
1851
1852* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
1853 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
1854
1855* New functions `ttyslot' and `syslog' from 4.4 BSD.
1856\f
1857Version 1.04
1858
1859* The configuration process has changed quite a bit. The `configure'
1860 script is now used just like the configuration scripts for other GNU
1861 packages. The `sysdeps' directory hierarchy is much rearranged.
1862 The file `INSTALL' explains the new scheme in detail.
1863
1864* The header files no longer need to be processed into ANSI C and
1865 traditional C versions. There is just one set of files to install, and
1866 it will work with ANSI or old C compilers (including `gcc -traditional').
1867
1868* Brendan Kehoe and Ian Lance Taylor have ported the library to the
1869 MIPS DECStation running Ultrix 4.
1870
1871* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
1872 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
1873 made itself into a shared library.
1874
1875* Yet further improved support for the i386, running 4.3 BSD-like systems
1876 (such as Mach 3 with the Unix single-server), or System V.
1877
1878* New function `strncasecmp' to do case-insensitive string comparison
1879 with limited length.
1880
1881* New function `strsep' is a reentrant alternative to `strtok'.
1882
1883* New functions `scandir' and `alphasort' for searching directories.
1884
1885* New function `setenv' is a better interface to `putenv'.
1886
1887* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
1888 function for traversing a directory tree.
1889
1890* The GNU obstack package is now also part of the C library.
1891 The new function `open_obstack_stream' creates a stdio stream that
1892 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
1893 formatted output directly to an obstack.
1894
1895* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
1896 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
1897
1898* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
1899
1900* The new functions `strfry' and `memfrob' do mysterious and wonderful
1901 things to your strings.
1902
1903* There are some new test programs: test-fseek, testmb, and testrand.
1904
1905* Some work has been done to begin porting the library to 4.4 BSD and Linux.
1906 These ports are not finished, but are a good starting place for really
1907 supporting those systems.
1908
1909* `/etc/localtime' is now the standard location for the file that says what
1910 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
1911 This follows the general principle that `/etc' is the place for all local
1912 configuration files.
1913
1914* The C library header files now use `extern "C"' when used by the C++
1915 compiler, so the C library should now work with C++ code.
1916
1917* The header file <bstring.h> is gone. <string.h> now declares bcopy,
56ddf355
UD
Ulrich Drepper2000-08-12 05:14:52 +00001918 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
1919 in <strings.h>.)

Roland McGrath1995-02-18 01:27:10 +00001920
1921* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
1922 function which uses the `merge sort' algorithm, and is said to be
1923 significantly faster than the old GNU `qsort' function. Merge sort is
1924 now the standard `qsort' function. The new algorithm can require a lot
1925 of temporary storage; so, the old sorting function is called when the
1926 required storage is not available.
1927
1928* The C library now includes Michael Glad's Ultra Fast Crypt, which
1929 provides the Unix `crypt' function, plus some other entry points.

Roland McGrath1995-02-18 01:27:10 +00001930
1931* The code and header files taken from 4.4 BSD have been updated with the
1932 latest files released from Berkeley.
