380d7e87 | 40 | |
a086b4d6 L |
41 | * Support for the x32 ABI on x86-64 added. The x32 target is selected by |
42 | configuring glibc with: | |
43 | BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32' | |
44 | Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info. | |
45 | Implemented by H.J. Lu. | |
46 | ||
380d7e87 UD |
47 | * ISO C11 support: |
48 | ||
49 | + define static_assert | |
50 | ||
51 | + do not declare gets | |
52 | ||
53 | + declare at_quick_exit and quick_exit also for ISO C11 | |
54 | ||
55 | + aligned_alloc. NB: The code is deliberately allows the size parameter | |
56 | to not be a multiple of the alignment. This is a moronic requirement | |
57 | in the standard but it is only a requirement on the caller, not the | |
58 | implementation. | |
8d44e150 | 59 | |
74033a25 | 60 | + timespec_get added |
544563c9 UD |
61 | |
62 | + uchar.h support added | |
d75a0a62 | 63 | |
ac097f5c UD |
64 | + CMPLX, CMPLXF, CMPLXL added |
65 | ||
16dd419d UD |
66 | Implemented by Ulrich Drepper. |
67 | ||
9dc4e1fb | 68 | * Support for the IA-64 has been moved to ports. |
33808bf1 UD |
69 | |
70 | * Remove support for anything but ELF binary format | |
d9a216c0 UD |
71 | |
72 | * Checking versions of poll, ppoll added. | |
73 | Implemented by Ulrich Drepper. | |
daa891c0 UD |
74 | |
75 | * More generic and 64-bit performance optimizations to math functions. | |
76 | Implemented by Ulrich Drepper. | |
021db4be AJ |
77 | |
78 | * New configure option --enable-obsolete-rpc makes the deprecated RPC | |
79 | headers and functions available at compile time as they were before | |
80 | version 2.14. This option will be removed at some time in the future | |
81 | after the TI-RPC library becomes fully sufficient for the needs of | |
82 | existing applications. | |
ffb7875d | 83 | |
21708942 | 84 | * Compatibility code for Linux kernel versions before 2.4 has been removed. |
ffb7875d JM |
85 | Note that glibc is not expected to work with any Linux kernel version |
86 | before 2.6. | |
83678f76 | 87 | |
edb00e4d RH |
88 | * New header <sys/auxv.h> and function getauxval allowing easy access to |
89 | the AT_* key-value pairs passed from the Linux kernel. The header also | |
90 | defines the HWCAP_* bits associated with the AT_HWCAP key. | |
91 | ||
83678f76 | 92 | * New locales: mag_IN |
7b44a2df RM |
93 | |
94 | * New configure option --enable-systemtap builds SystemTap static probes | |
95 | into libc for setjmp and longjmp and into libpthread for various operations. | |
96 | So far the setjmp/longjmp probes and some of the libpthread probes are | |
97 | provided only for i*86 and x86_64. | |
98 | Implemented by Roland McGrath and Rayson Ho. | |
47e452cf JM |
99 | |
100 | * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva. | |
101 | ||
d9dc34cd TMQMF |
102 | * More optimized functions for PowerPC. Implemented by Adhemerval Zanella |
103 | and Will Schmidt. | |
47e452cf JM |
104 | |
105 | * More optimized functions for SPARC. Implemented by David S. Miller. | |
106 | ||
107 | * Improved support for cross-compilation, especially bootstrap builds | |
108 | without a previously built glibc. | |
109 | ||
110 | * Ports for the TILE-Gx and TILEPro families of processors. Contributed by | |
111 | Chris Metcalf from Tilera. | |
112 | ||
113 | * Support for the old ARM ABI has been removed from ports. Only the EABI is | |
114 | now supported for ARM processors. | |
115 | ||
116 | * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3 | |
117 | as the name of the dynamic linker, to distinguish it from the | |
118 | /lib/ld-linux.so.3 dynamic linker used for the base EABI. | |
119 | ||
120 | * Support for CRIS has been removed from ports. | |
d9dc34cd TMQMF |
121 | |
122 | * A new class of installed header has been documented for low-level | |
123 | platform-specific functionality. PowerPC added the first instance with a | |
124 | function to provide time base register access. Contributed by Tulio | |
125 | Magno Quites Machado Filho. | |
929cc14e AJ |
126 | |
127 | * ix86 configurations now install header files that are consistent with | |
128 | what x86-64 configurations install. These same header files can be used | |
129 | for -m32, -m64, or -mx32 builds. | |
130 | Contributed by H.J. Lu. | |
ee9247c3 CD |
131 | |
132 | * Math library bug fixes. A thorough audit of all open math library bugs was | |
133 | conducted by Joseph Myers. Significant progress was made on many math | |
134 | library bugs resulting in more accurate exceptions and function results. | |
135 | Many thanks to all those that contributed including Andreas Jaeger for his | |
136 | patch review and work on the x87 trigonometric instruction issues. | |
137 | ||
138 | * Timezone data is no longer installed. Timezone-related binaries and scripts | |
139 | will continue to be installed. Users should obtain their timezone data from | |
140 | their distribution provider or from the tzdata package at | |
141 | <ftp://munnari.oz.au/pub/>. | |

7b57bfe5 UD |
222 | * The RPC implementation in libc is obsoleted. Old programs keep working |
223 | but new programs cannot be linked with the routines in libc anymore. | |
224 | Programs in need of RPC functionality must be linked against TI-RPC. | |
6b1e7d19 | 225 | The TI-RPC implementation is IPv6 enabled and there are other benefits. |
018b9e36 UD |
226 | |
227 | Visible changes of this change include (obviously) the inability to link | |
a0446976 UD |
228 | programs using RPC functions without referencing the TI-RPC library and the |
229 | removal of the RPC headers from the glibc headers. | |
7b57bfe5 UD |

241 | Implemented by Ulrich Drepper. | |
7d17596c UD |
242 | |
243 | * The malloc hook implementation is marked deprecated and will be removed | |
244 | from the default implementation in the next version. The design never | |
245 | worked ever since the introduction of threads. Even programs which do | |
246 | not create threads themselves can use multiple threads created internally. | |

342 | broken environments. If two requests from the same port are not | |
343 | handled correctly close the socket and open a new one before sending | |
344 | the second request. The 'single-request-reopen' option in /etc/resolv.conf | |
345 | can be used to select this mode right away, instead of rediscovering the | |

394 | ||
395 | * The malloc implementation can be compiled to be less memory efficient | |
396 | but higher performing in multi-threaded programs. | |
397 | Implemented by Ulrich Drepper. | |
398 | ||
735be400 | 399 | * New locales: nan_TW@latin, ks_IN |

415 | 'options single-request' in /etc/resolv.conf. | |
416 | Implemented by Ulrich Drepper. | |

449 | * Implement "b" mode for fmemopen. In this mode writes writes don't |
450 | implicitly add a NUL byte and seeks from the end of the buffer really | |
451 | use the buffer end, not the string length as the basis. | |
452 | Implemented by Ulrich Drepper. | |
453 | ||
e038616f UD |
454 | * Many functions, exported and internal, now atomically set the close-on-exec |

585 | 3225, 3251, 3252, 3253, 3273 | |
586 | ||
3af48b5b | 587 | * For Linux, the sorting of addresses returned by getaddrinfo now also |
457b559e UD |
588 | handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled. |
589 | Implemented by Ulrich Drepper. | |
3af48b5b | 590 | |
3142b1ac UD |
591 | * Allow system admin to configure getaddrinfo with the /etc/gai.conf file. |
592 | Implemented by Ulrich Drepper. | |
593 | ||
871b9158 | 594 | * New Linux interfaces: splice, tee, sync_file_range, vmsplice. |
1e528c6e UD |
595 | |
596 | * New iconv module for MIK. Contributed by Alexander Shopov. | |
3af48b5b | 597 | |
3142b1ac UD |
598 | * For sites with broken group and/or passwd database, the auto-propagate |
599 | option of nscd can prevent creating ID lookup entries from the results | |
600 | of a name lookup and vice versa. This usually is no problem but some | |
457b559e | 601 | site might have problems with the default behavior. |
3142b1ac UD |
602 | Implemented by Ulrich Drepper. |
603 | ||
07bfff20 | 604 | * Iterating over entire database in NIS can be slow. With the |
3142b1ac UD |
605 | SETENT_BATCH_READ option in /etc/default/nss a system admin can decide |
606 | to trade time for memory. The entire database will be read at once. | |
607 | Implemented by Ulrich Drepper. | |
608 | ||
07bfff20 UD |
609 | * The interfaces introduced in RFC 3542 have been implemented by |
610 | Ulrich Drepper. | |
611 | ||
871b9158 UD |
612 | * Support for the new ELF hash table format was added by Ulrich Drepper. |
613 | ||

615 | Ulrich Drepper. | |
616 | ||
ad2a3c07 UD |
617 | * Support for priority protected mutexes added by Jakub Jelinek. |
618 | ||
88cc61e8 UD |
619 | * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN, |
620 | or_IN, csb_PL, fy_NL, sr_ME. | |
2e92188d | 621 | \f |

622 | Version 2.4 |
623 | ||
624 | * More overflow detection functions. | |
625 | ||
626 | * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153, | |
627 | IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba. | |

633 | IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed | |
634 | by Masahide Washizawa. | |
635 | ||
1aa4e40a UD |
636 | * It is now possible to install audit libraries for the dynamic linker using |
637 | LD_AUDIT. Implemented by Ulrich Drepper. | |
da0eaa47 RM |
638 | |
639 | * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no | |
640 | longer supported. The new NPTL implementation requires Linux 2.6 kernels. | |
641 | For a libc and libpthread that works well on Linux 2.4 kernels, we | |
642 | recommend using the stable 2.3 branch. | |
4973cbe5 | 643 | |
35129bc0 RM |
644 | * The new function open_wmemstream acts like open_memstream, |
645 | but uses a wchar_t wide character buffer. | |
646 | ||
647 | * The new function ppoll is an improved version of poll, similar to pselect. | |
648 | ||
649 | * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat, | |
650 | futimesat, faccessat, mkdirat, mkfifoat, mknodat, | |
651 | renameat, unlinkat, linkat, symlinkat, readlinkat. | |
652 | ||
653 | * New Linux kernel system calls: unshare, | |
654 | inotify_init, inotify_add_watch, inotify_rm_watch. | |
655 | ||
656 | * The euidaccess function is now also known by the alias eaccess, | |
657 | for compatibility with some other systems. | |
658 | ||
659 | * Timezone data updated to 2006b version. | |
137e6462 | 660 | \f |

a55bda85 UD |
689 | Version 2.3.4 |
690 | ||
691 | * Support for RFC 3678. Real implementations exist only for Linux so far. | |
692 | Implemented by Ulrich Drepper. | |
8a1f658b UD |
693 | |
694 | * nscd can now cache entries persistently. Expiring entries are reloaded. | |
695 | For speedups the cache can be shared in memory with client processes. | |
696 | Implemented by Ulrich Drepper. | |
697 | ||
698 | * nscd can now perform SELinux checks. | |
699 | Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>. | |
700 | ||
0325dd20 | 701 | * getaddrinfo queries are now cached. Canonical name lookup is performed |
8a1f658b UD |
702 | efficiently. |
703 | Implemented by Ulrich Drepper. | |
704 | ||
705 | * The nothrow function attribute is used when headers are used by gcc when | |
706 | compiling C code. This can avoid significant amounts of exception | |
707 | handling data. | |
708 | ||
709 | * The malloc functions perform more error checking and are stricter when | |
710 | it comes to reacting on errors. The default action is to terminate | |
0325dd20 | 711 | the process after showing an error message. Implemented by Ulrich Drepper. |
8a1f658b UD |
712 | |
713 | * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int | |
0325dd20 UD |
714 | lookups anymore unless explicitly requested. Implemented by Ulrich Drepper. |
715 | ||
716 | * Namespaces in ld.so are implemented. DSOs can be loaded in separate | |
717 | namespaces using the new function dlmopen(). This feature is of course, | |
718 | like most other dynamic loading functionality, not available in statically | |
719 | linked applications. Implemented by Ulrich Drepper. | |
720 | ||
721 | * Low-overhead boundary checking variants of string and some stdio functions | |
722 | were added. These are to be used in conjunction with a gcc patch by | |
723 | Jakub Jelinek which adds calls to these functions if possible. | |
720817e7 RM |
724 | Implemented by Jakub Jelinek and Ulrich Drepper. |
725 | ||
726 | * Old code for several operating systems and machine architectures that | |
727 | have not been in working condition in a long time have been removed from | |
728 | the main source tree maintained by the GNU C Library's maintainers. | |
729 | These files are now reside in the separate `ports' source module | |
730 | that is usable as an add-on when building the library. | |
a55bda85 | 731 | \f |
3a601d31 RM |
732 | Version 2.3.3 |
733 | ||
45e4762c RM |
734 | * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to |
735 | interrogate the dynamic linker, compatible with the Solaris interface. | |
736 | ||
3a601d31 RM |
737 | * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64; |
738 | implemented by Paul Mackerras, Steven Munroe, and Roland McGrath. | |
925c3c5c | 739 | |
69be6aaf | 740 | * getifaddrs now uses the netlink interface on Linux to get its information. |
925c3c5c UD |
741 | Implemented by Thorsten Kukuk. |
742 | ||
743 | * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF. | |
744 | Implemented by Ulrich Drepper. | |
97fd3a30 UD |
745 | |
746 | * support for non-executable stacks on x86 has been added. Changes mostly | |
747 | by Roland McGrath. | |
748 | ||
c5af724c | 749 | * regex is now much faster for multibyte locales. Changes by Jakub Jelinek |
97fd3a30 UD |
750 | and Ulrich Drepper. |
751 | ||
752 | * getaddrinfo now performs destination address selection according to | |
753 | RFC 3484. | |
3a601d31 | 754 | \f |
747bf98e RM |
755 | Version 2.3.2 |
756 | ||
f87277f2 RM |
757 | * Thread-safe interfaces for many functions that access locale data |
758 | were added in version 2.3, but these features were omitted from NEWS. | |
759 | Many functions have variants with an `_l' suffix that take a `locale_t' | |
760 | object as a parameter rather than consulting the current locale. | |
761 | The new functions `newlocale', `duplocale', and `freelocale' in <locale.h> | |
762 | create and maintain `locale_t' objects. Additionally, the new function | |
763 | `uselocale' sets "the current locale" (as used by functions not so | |
764 | parameterized) set for an individual thread. These features were added | |
765 | in version 2.3, implemented by Ulrich Drepper and Roland McGrath. | |
766 | ||
747bf98e RM |
767 | * The functions getresuid, getresgid, setresuid, and setresgid, which |
768 | have long been available on Linux, are now declared in <unistd.h> | |
769 | and are now also available on the Hurd. | |
770 | ||
771 | * ELF thread-local storage support (TLS) now works on x86-64. | |
d62507dd RM |
772 | |
773 | * The new dynamic string token $LIB is expanded in shared library names. | |
774 | This normally expands to lib, but on some 64-bit platforms to lib64 instead. | |
52a16e58 | 775 | |
f87277f2 RM |
776 | * Aldy Hernandez contributed complete software floating point support for |
777 | PowerPC machines with no FPU. | |
778 | ||
52a16e58 | 779 | * fexecve is implemented on Linux. |
f9ad060c | 780 | |
f87277f2 RM |
781 | * The `btowc' function should work at least twice as fast due to |
782 | specialized callbacks in the iconv modules. Implemented by Bruno Haible. | |
9ef0a840 UD |
783 | |
784 | * With approriate thread add-ons cancelable functions are now implemented | |
785 | in libc.so as well. No need to call the function in libpthread. This | |
786 | change allowed to finally disable the incorrect and expensive handling | |
787 | of weak definition in ld.so. | |
788 | ||
789 | * Yet more PLT entries in libc.so have been removed. We finally arrived | |
790 | at the bare minimum. Startup times improved appropriately. | |
791 | ||
792 | * Support for the new Linux/x86 system call interface was added. The | |
793 | AT_SYSINFO auxiliary vector entry is recognized and handled. | |
747bf98e | 794 | \f |
03a2c647 | 795 | Version 2.3 |
37fb1084 | 796 | |
03a2c647 UD |
797 | * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164 |
798 | charsets. | |
799 | ||
800 | * iconv (the program and the interface) now accepts empty names (excluding | |
801 | options like //TRANSLIT) to mean "use charset of current locale". | |
47e8b443 | 802 | |
bb0ec5bd | 803 | * localedef can now transliterate characters in strings which are not in |
47e8b443 | 804 | the provided charmap. The information from the input locale is used. |
c17f665b UD |
805 | |
806 | * Prelinking support was added for ELF targets. This requires additional | |
807 | tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek. | |
8e57fc70 | 808 | |
bb0ec5bd | 809 | * Read-only stdio streams now use mmap to speed up operation by eliminating |
91e6367e UD |
810 | copying and buffer underflows. To use add 'm' to the mode string of |
811 | the fopen/fdopen/freopen call. Implemented by Ulrich Drepper. | |
207b66ce UD |
812 | |
813 | * The malloc functions were completely rewritten by Wolfram Gloger based | |
814 | on Doug Lea's malloc-2.7.0.c. | |
3b0bdc72 | 815 | |
bb0ec5bd | 816 | * Isamu Hasegawa contributed a completely new and POSIX-conformant |
3b0bdc72 | 817 | implementation of regex. |
02779eaa UD |
818 | |
819 | * Bruno Haible upgraded the iconv and locale implementation to support | |
820 | Unicode 3.2. | |
be45f421 | 821 | |
bb0ec5bd RM |
822 | * Contents of the LC_* and LANG environment variables in the CEN style are |
823 | not recognized anymore. It never was used. Change by Ulrich Drepper. | |
be45f421 | 824 | |
bb0ec5bd RM |
825 | * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF |
826 | thread-local storage (TLS) ABI on some platforms. | |
827 | Changes by Ulrich Drepper. SH support by Kaz Kojima. | |
be45f421 UD |
828 | |
829 | * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213, | |
f87277f2 | 830 | EUC-JISX0213, and TSCII. |
a753ffb2 RM |
831 | |
832 | * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs': | |
833 | BSD-compatible interface for getting all network interface addresses. | |
834 | Implementation for IPv4 by Roland McGrath. | |
6a9340b5 UD |
835 | |
836 | * Loading of locale data is faster due to the introduction of a locale | |
837 | archive. Implemented by Roland McGrath and Ulrich Drepper. | |
dd4f2115 UD |
838 | |
839 | * Startup times are significantly reduced by not using exported functions | |
840 | inside the library itself. Changes by Jakub Jelinek, Roland McGrath, | |
841 | and Ulrich Drepper. | |
c843e065 RM |
842 | |
843 | * Steven Munroe contributed a port to PowerPC64/Linux. | |
844 | \f | |
45061a15 RM |
845 | Version 2.2.6 |
846 | ||
847 | * The Hurd now uses the GNU libio implementation of stdio rather than the | |
848 | old GNU stdio implementation, and uses a new ABI (libc.so.0.3). | |
849 | ||
850 | * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file | |
851 | with the same behavior as the Linux system call of the same name. | |
03a2c647 | 852 | \f |
a8ae31c2 UD |
853 | Version 2.2.5 |
854 | ||
76321a25 AJ |

866 | as well. | |
867 | ||
45061a15 RM |
868 | * optimizations in the dynamic linker. Binaries created by recent binutils |
869 | versions start up quicker due to reduced time spent on relocations. | |
8e57fc70 UD |
870 | |
871 | * Support for use of gcc3 added by Jakub Jelinek and HJ Lu. | |

33996419 AJ |
873 | Version 2.2.4 |
874 | ||
2995f70e | 875 | * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, |
aff17a50 | 876 | asinh, atanh, j0 for the 128-bit long double format. |
8fee1bb0 UD |
877 | |
878 | * Bruno Haible updated all the code handling Unicode in some form to | |
879 | support Unicode 3.1. | |
86dbe05e UD |
880 | |
881 | * Speed of regex for single-byte locales is back to previous levels. | |
882 | Patch by Isamu Hasegawa. | |
045fcd26 | 883 | |
69d5f925 | 884 | * Alpha, SPARC, and IA-64 now also using floating stacks. |
045fcd26 | 885 | |
69d5f925 | 886 | * Startup time of internationalized applications greatly improved through |
045fcd26 UD |
887 | iconv cache. Use iconvconfig to generate the cache file. |
888 | Contributed by Ulrich Drepper. | |
889 | ||
890 | * The IA-64 specific part of ld.so was rewritten to eliminate some pretty | |
891 | severe performance problems. Patch by David Mosberger. | |
892 | ||
893 | * The Hurd port got a lot more functionality like AIO, various stdio | |
894 | extensions, etc. Mainly done by Roland McGrath. | |
129d706d UD |
895 | |
896 | * mtrace can now lookup symbols in shared libraries. | |

2ace5721 UD |
898 | Version 2.2.3 |
899 | ||
1746f2b0 | 900 | * Intel's IA-64 math library is largely integrated. It provides fast and |
2ace5721 UD |
901 | accurate implementatations for most basic and standard math functions |
902 | in float, double, and long double format. | |
903 | ||
f128331c | 904 | * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, |
b8750342 UD |
905 | and asin for the 96-bit long double format and asin, log, tan for the |
906 | 128-bit long double format. | |
07f951e4 | 907 | |
e4d82761 UD |
908 | * The beginning of a last-bit accurate math library by IBM Haifa were added. |
909 | The basic double functions exist today. Contributed by Abraham Ziv | |
910 | <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis | |
911 | <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. | |
912 | ||
2ace5721 UD |
913 | * An asynchronous name lookup library was added. The interface is designed |
914 | after POSIX AIO. The proposal was circulated beforehand to get comments. | |
915 | No negative ones came in. Implemented by Ulrich Drepper. | |
b8a8413c UD |
916 | |
917 | * Port to S390/64bit contributed by Martin Schwidefsky | |
918 | <schwidefsky@de.ibm.com>. | |
a66f0958 UD |
919 | |
920 | * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family | |
921 | of functions for Linux/IA-64. | |
481b550f UD |
922 | |
923 | * The RPC code is now thread safe. Threads can now use the same service | |
924 | of different services at the same time. Patch by Eric Norum | |
925 | <eric.norum@usask.ca> with some help by Ulrich Drepper. | |
f128331c UD |
926 | |
927 | * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext | |
928 | family of functions for Linux/S390. | |
232fdf8c UD |
929 | |
930 | * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family | |

306eeae5 UD |
935 | Version 2.2.2 |
936 | ||
464d97ec | 937 | * Lots of headers were cleaned up. Using the tool in the conform/ subdir |
306eeae5 UD |
938 | we can now check for namespace violations and missing declarations. The |
939 | result is that almost all headers are now Unix-compliant (as defined in | |
940 | the upcoming XPG6). The negative side is that some programs might need | |
941 | corrections, too, if they depend on the incorrect form of the headers in | |
942 | previous versions which defined too many symbols and included too many | |
943 | other headers. | |
464d97ec UD |
944 | |
945 | * regex now handles multibyte character sets correctly. | |
946 | Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. | |
947 | ||
948 | * iconv (the program) does now conform to the upcoming XPG6 and handles | |
949 | charmaps. Instead of the charset names the path of charmaps can be | |
950 | provided and the conversion happens based on this data. | |
951 | Contributed by Ulrich Drepper. | |
952 | ||
953 | * The locale program now provides detailed information about the installed | |
954 | locales. While | |
955 | ||
956 | locale -a | |
957 | ||
958 | only lists the names of the supported locales | |
959 | ||
960 | locale -a --verbose | |
961 | ||
962 | provides details such as country, language, and codeset name. | |

306eeae5 | 964 | \f |
d2defdc4 UD |
965 | Version 2.2.1 |
966 | ||
967 | * The gencat program now parses the input file according to the charset | |
968 | selected by the LC_CTYPE category. This is important for stateful | |
969 | character sets. To make generating catalogs easier there is a way | |
970 | to overwrite the charset selected by the locale: before the first | |
971 | message or $ quote line the catalog can contain a line like | |
972 | ||
973 | $ codeset=ISO-8859-2 | |
974 | ||
975 | to select the charset (ISO-8859-2 in this case). | |
976 | ||
977 | Implemented by Shinya Hanataka and Ulrich Drepper. | |
aea6353a UD |
978 | |
979 | * New codeset conversion modules: IBM-922 (Estonia PC codeset), | |
980 | IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). | |
981 | Contributed by Masahide Washizawa <washi@jp.ibm.com>. | |

982 | |
983 | * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson | |
984 | <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. | |
985 | ||
986 | * The LANGUAGE environment variable is now ignored unless the locale is | |
987 | changed from the default "C" locale. | |
988 | ||
989 | * The usual bug fixes. | |
d2defdc4 | 990 | \f |
2e92188d UD |
991 | Version 2.2 |
992 | ||
08a2e4a0 GM |
993 | * Greg McGary added runtime support for bounds checking using gcc's |
994 | new -fbounded-pointers option. ix86 target is complete. PowerPC | |
995 | is in progress. | |
996 | ||
2e92188d UD |
997 | * Thorsten Kukuk added secure mode support to nscd. |
998 | ||
793bd4d9 | 999 | * The Berkeley db libraries have been removed. |
2e92188d | 1000 | |
47b853e8 UD |
1001 | Related, the nss_db module is now in a separate package since it |
1002 | obviously requires a database library being available. | |
1003 | ||
0013b2b1 UD |
1004 | * Wide character I/O streams implemented by Ulrich Drepper. |
1005 | ||
abbffdf9 | 1006 | * Functions from the extended socket API added by Ulrich Drepper. |
01c771d0 | 1007 | |
6e8afc1c UD |
1008 | * Functions feenableexcept and fedisableexcept to control the |
1009 | behaviour of individual exceptions have been added by Andreas Jaeger. | |
1010 | ||
591e1ffb UD |
1011 | * ldconfig program added by Andreas Jaeger and Jakub Jelinek. |
1012 | ||
d3436b3c UD |
1013 | * The resolver code has been updated from bind 8.2.3-T5B which supports |
1014 | threads. The integration was done by Andreas Jaeger, Adam D. Bradley, | |
1015 | and Mark Kettenis. | |
2588068b UD |
1016 | |
1017 | This change could in some situations effect backward compatibility. Since | |
1018 | now `_res' is a thread-local instead of a global variable, modifying it | |
1019 | in one thread does not have any effect in other threads. | |
66ac0abe | 1020 | |
a00c3ca9 | 1021 | The resolver library was also extended to allow IPv6 as the transport |
d3436b3c UD |
1022 | protocol for the requests. This work was done by Stig Venaas. |
1023 | ||
1c5d4617 UD |
1024 | * Compatibility code for K&R C compilers has been removed from the |
1025 | header files. A ISO C compiler is needed to use the library | |
1026 | (conforming to either C89 or C99 standard). | |
1027 | ||
abbffdf9 UD |
1028 | * Complete rewrite of the localedef program to support multibyte character |
1029 | sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, | |
1030 | strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. | |
1031 | Implemented by Ulrich Drepper. | |
1032 | ||
8f3f1e09 UD |
1033 | Bruno Haible significantly improved the generation and use of the data |
1034 | structures for the wide character tables. | |
1035 | ||
abbffdf9 UD |
1036 | * Plural handling in gettext implemented by Ulrich Drepper. |
1037 | ||
69173865 UD |
1038 | * The utmp daemon has been removed. |
1039 | ||
1040 | * The port to MIPS-Linux has been finished by Andreas Jaeger. | |
1041 | ||
37fb8add UD |
1042 | * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima |
1043 | and Yutaka Niibe. | |
1044 | ||
594cee6c UD |
1045 | * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. |
1046 | ||
40c4c9b5 UD |
1047 | * POSIX barriers implemented by Kaz Kylheku. |
1048 | ||
594cee6c UD |

1050 | ||
1051 | * POSIX spinlocks are now available. | |
1052 | ||
40c4c9b5 UD |
1053 | * Timed wait functions for mutex, rwlock, and semaphores are implemented. |
1054 | ||
8f3f1e09 UD |
1055 | * the configure option --enable-kernel=X.Y.Z allows to strip out |
1056 | compatibility for kernel versions before X.Y.Z. This is currently only | |
1057 | implemented for Linux. | |
1058 | ||
3107c0c5 UD |
1059 | * the sockaddr_in6 structure changed. The IPv6 working group added a new |
1060 | field sin6_scope_id. This means that all programs using IPv6 should be | |
1061 | recompiled. Don't expect binary compatibility with previous glibc | |
1062 | versions. | |
1063 | ||
d2830ba4 UD |
1064 | * various conversion modules for IBM character sets contributed by |
1065 | Masahide Washizawa. | |

1082 | ||
16b0f634 UD |
1083 | * New xdr functions are added; some rpc functions are now 64bit clean. |
1084 | ||
407d26b7 | 1085 | * Fixed a number of bugs and memory leaks (especially in NIS+ code). |
16b0f634 UD |
1086 | |
1087 | * Fixed known incompatibilities with glibc 2.0. | |
1088 | ||
407d26b7 | 1089 | * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. |
16b0f634 | 1090 | |
407d26b7 | 1091 | * Optimized a number of functions (especially the ELF dynamic loader). |
16b0f634 UD |
1092 | |
1093 | * Update timezone data files. | |
27995311 | 1094 | |
554b8800 UD |
1095 | * lots of charmaps corrections |
1096 | ||

c84142e8 UD |
1100 | Version 2.1 |
1101 | ||
da2d1bc5 UD |
1102 | * Richard Henderson corrected size of struct timeval on Linux/Alpha to |
1103 | conform to POSIX member type requirements. Symbol versions have been | |
1104 | adjusted as needed within the library, and for direct use by applications, | |
1105 | but there is potential for problems if third-party libraries use | |
1106 | struct timeval as part of their interface. This does not present | |
1107 | a problem for X and other "essential" system libraries. | |
1108 | ||
c84142e8 | 1109 | * An additional locale model to support C++ Standard Library locale |
1fb05e3d | 1110 | model and probably more was implemented by Ulrich Drepper. |
c84142e8 | 1111 | |
1fb05e3d | 1112 | * Eric Youngdale and Ulrich Drepper implemented versioning of objects on |
c84142e8 UD |
1113 | symbol level. |
1114 | ||
1115 | * Miles Bader provided the `argp' function family to support hierachical | |
1116 | command line argument parsing, layered on top of getopt. | |
377a515b | 1117 | |
cbdee279 | 1118 | * strtod accepts new hexadecimal floating-point format from ISO C 9X. |
377a515b UD |
1119 | |
1120 | * printf has two new specifiers %a and %A to print hexadecimal flaoting-point | |
cbdee279 | 1121 | numbers. |
377a515b | 1122 | |
cbdee279 | 1123 | * scanf recognizes the %a and %A format for scanning floating point numbers. |
e61abf83 | 1124 | |
48869012 UD |
1125 | * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides |
1126 | information and interfaces for the available integer types. | |
e61abf83 | 1127 | |
813f4f4d UD |
1128 | * about 130 new math functions were added to implement the ISO C9x math |
1129 | library. | |
1130 | ||
e61abf83 | 1131 | * the new header <complex.h> contains definitions of the complex math |
cbdee279 UD |
1132 | functions from ISO C 9X. |
1133 | ||
1134 | * the new header <tgmath.h> defines generic macros to use complex or | |
1135 | real valued functions. | |
e61abf83 | 1136 | |
a5a0310d | 1137 | * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2. |
e61abf83 | 1138 | |
a5a0310d UD |
1139 | * Andreas Jaeger provided a test suite for the math library. |

1141 | * Mark Kettenis implemented the utmpx interface and an utmp daemon. | |
cbdee279 | 1142 | |
440d13e2 | 1143 | * Ulrich Drepper added character set conversion functions (iconv). |
cbdee279 UD |
1144 | |
1145 | * Optimized string functions have been added. | |
1146 | ||
1147 | * The localedata addon is now part of glibc. | |
2eb45444 UD |
1148 | |
1149 | * An implementation of profiling shared libraries was added by Ulrich Drepper. | |
ea278354 | 1150 | |
48244d09 UD |
1151 | * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching |

0dee6738 UD |
1175 | [1] The old nscd implementation is not available anymore since it was |
1176 | distributed with glibc up to version 2.0.98 and thus is now replaced. | |

40a4b79f | 1575 | Version 2.0 |
28f540f4 | 1576 | |
d3669add RM |
1577 | * GNU extensions are no longer declared by default. To enable them you |
1578 | must define the macro `_GNU_SOURCE' in your program or compile with | |
1579 | `-D_GNU_SOURCE'. | |
1580 | ||
28f540f4 RM |
1581 | * The library has changed from using GNU ld symbol aliases to using weak |
1582 | symbols where available. The ELF object file format supports weak | |
1583 | symbols; GNU ld also supports weak symbols in the a.out format. (There | |
1584 | is also now support for other GNU ld extensions in ELF. Use the | |
787126fe RM |
1585 | `--with-elf' option to configure to indicate you have ELF, and |
1586 | `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion | |
28f540f4 RM |
1587 | of many files which contained only symbol aliases, reducing the size of |
1588 | the source and the compiled library; many other files were renamed to | |
1589 | less cryptic names previously occupied by the symbol alias files. | |
dcf0671d UD |
1590 | There is a new header file <elf.h> for programs which operate on |
1591 | files in the ELF format. | |
49e522bf RM |
1592 | |
1593 | * Converted to Autoconf version 2, so `configure' has more options. | |
1594 | Run `configure --help' to see the details. | |
1595 | ||
1596 | * The library can now be configured to build profiling, highly-optimized | |
b25c5d66 RM |
1597 | (but undebuggable), and/or shared libraries (ELF with GNU ld only). The |
1598 | `--enable-profile', `--enable-omitfp', and `--enable-shared' options to | |
1599 | `configure' enable building these extra libraries. The shared library is | |
1600 | built by default when using both ELF and GNU ld. When shared libraries | |
1601 | are enabled, the new library `-ldl' is available for arbitrary run-time | |
1602 | loading of shared objects; its interface is defined in <dlfcn.h>. The | |
1603 | new header file <link.h> gives access to the internals of the run-time | |
33a934a3 UD |
1604 | dynamic linker, `ld.so'. The shell script `ldd' is similar to the |
1605 | application of same name on other systems and it provides information | |
1606 | about dynamically linked binaries. | |
49e522bf | 1607 | |
71733723 RM |
1608 | * The C library now provides the run-time support code for profiling |
1609 | executables compiled with `-pg'. Programs can control the profiling code | |
d3669add RM |
1610 | through the interface in <sys/gmon.h>. The `gmon.out' files written by |
1611 | the GNU C library can be read only by GNU `gprof' (from GNU binutils); | |
1612 | the support for this file format was contributed by David Mosberger-Tang. | |
71733723 | 1613 | |
f7eac6eb | 1614 | * The math code has been replaced with a math library based on fdlibm from |
33a934a3 UD |
1615 | Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by |
1616 | Ian Taylor with `float' functions and by Ulrich Drepper with `long double' | |
1617 | functions. The math functions now reside in a separate library, so | |
1618 | programs using them will need to use `-lm' their linking commands. | |
1619 | ||
1620 | * John C. Bowman contributed optimized ix87 assembler inline functions. | |
f7eac6eb | 1621 | |
5f0e6fc7 RM |
1622 | * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' |
1623 | mechanism similar to that found in Solaris 2. This is now used for the | |
33a934a3 UD |
1624 | group, passwd, hosts, networks, services, protocols, rpc, ethers, |
1625 | shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' | |
1626 | file controls what services are used for each individual database. This | |
1627 | works by loading shared libraries with names specified in `nsswitch.conf', | |
1628 | so service modules can be changed or added at any time without even | |
1629 | relinking any program. Currently there are the file, db, and NIS based | |
1630 | NSS services available. | |
5f0e6fc7 | 1631 | |
49e522bf RM |
1632 | * The new functions `strtoq' and `strtouq' parse integer values from |
1633 | strings, like `strtol' and `strtoul', but they return `long long int' and | |
1634 | `unsigned long long int' values, respectively (64-bit quantities). | |
1635 | ||
1636 | * The new functions `strtof' and `strtold' parse floating-point values from | |
1637 | strings, like `strtod', but they return `float' and `long double' values, | |
1638 | respectively (on some machines `double' and `long double' are the same). | |
1639 | ||
1640 | * Ulrich Drepper has contributed new implementations of the floating-point | |
1641 | printing and reading code used in the `printf' family of functions and | |
1642 | `strtod', `strtof', and `strtold'. These new functions are perfectly | |
1643 | accurate, and much faster than the old ones. | |

1645 | * The implementation of the POSIX locale model was completely rewritten by |
1646 | Ulrich Drepper. This includes the new programs `localedef' and `locale' | |
1647 | to compile the POSIX locale definition. | |
1648 | ||
1649 | * The former dummy implementations of the strcoll and strxfrm function are | |
1650 | now replaced by fully functional code contributed by Ulrich Drepper. The | |
1651 | collation information comes from the POSIX locale definitions. | |
1652 | ||
49e522bf RM |
1653 | * The new header <langinfo.h> defines an interface for accessing |
1654 | various locale-dependent data (using the locale chosen with `setlocale'). | |
1655 | ||
f7eac6eb | 1656 | * Ulrich Drepper has contributed a new suite of functions for operation on |
33a934a3 | 1657 | wide-character and multibyte-character strings, in <wchar.h>; |
b7407d63 | 1658 | and classification and case conversion of wide characters, in <wctype.h>. |
33a934a3 UD |
1659 | These new functions are conforming to the ISO C, Amendement 1 specification. |
1660 | ||
1661 | * There is now a second implementation of the standard I/O library available. | |
1662 | It comes from GNU libg++ as was written by Per Bothner, heavily modified | |
1663 | by Hongjiu Lu and made thread safe by Ulrich Drepper. | |
f7eac6eb | 1664 | |
71733723 | 1665 | * You can now use positional parameter specifications in format strings |
49e522bf RM |
1666 | for the `printf' and `scanf' families of functions. For example, |
1667 | `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints | |
1668 | ``Number 6, Mr Jones''. This is mainly useful when providing different | |
d365fd2c RM |
1669 | format strings for different languages, whose grammars may dictate |
1670 | different orderings of the values being printed. To support this | |
49e522bf | 1671 | feature, the interface for `register_printf_handler' has changed; see |
d365fd2c | 1672 | the header file <printf.h> for details. |
49e522bf RM |
1673 | |
1674 | * The `printf' and `scanf' families of functions now understand a new | |
1675 | formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says | |
1676 | to group numbers as indicated by the locale; for `scanf' and friends, this | |
1677 | says to accept as valid only a number with all the proper grouping | |
1678 | separators in the right places. In the default "C" locale, numbers are | |
1679 | not grouped; but locales for specific countries will define the usual | |
1680 | conventions (i.e. separate thousands with `,' in the US locale). | |
28f540f4 RM |
1681 | |
1682 | * The pgrp functions have been regularized, slightly incompatibly but much | |
1683 | less confusingly. The core functions are now `getpgid' and `setpgid', | |
1684 | which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no | |
1685 | argument) and BSD `setpgrp' (identical to `setpgid') functions are | |
1686 | provided for compatibility. There is no longer an incompatible `getpgrp' | |
1687 | with an argument declared under _BSD_SOURCE; no BSD code uses it. | |
1688 | ||
1689 | * The new header file <fts.h> and suite of functions simplify programs that | |
1690 | operate on directory trees. This code comes from 4.4 BSD. | |
1691 | ||
33a934a3 UD |
1692 | * The resolver code has been updated from the BIND 4.9.5-P1 release. |
1693 | Parts of the code were heavily modified by Ulrich Drepper to fit in the | |
1694 | NSS scheme used in glibc. | |
28f540f4 | 1695 | |
28f540f4 RM |
1696 | * There is a new malloc debugging hook `__memalign_hook'. |
1697 | ||
1698 | * There are new typedefs `ushort' for `unsigned short int' and `uint' for | |
1699 | `unsigned int' in <sys/types.h>. These are for compatibility only and | |
1700 | their use is discouraged. | |
1701 | ||
1702 | * The `-lmcheck' library to enable standard malloc debugging hooks is now | |
1703 | done differently, so that it works even without GNU ld. | |
787126fe | 1704 | |
22a1292a RM |
1705 | * New function `euidaccess' checks allowed access to a file like `access', |
1706 | but using the effective IDs instead of the real IDs. | |
49e522bf RM |
1707 | |
1708 | * The time zone data files have been updated for the latest and greatest | |
1709 | local time conventions of the countries of the world. | |
1710 | ||
1711 | * The new function `dirfd' extracts the file descriptor used by a DIR stream; | |
1712 | see <dirent.h>. | |
1713 | ||
1714 | * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface | |
1715 | for formatting floating-point numbers. They are provided only for | |
33a934a3 UD |
1716 | compatibility; new programs should use `sprintf' instead. There are |
1717 | also equivalent function for the `long double' floating-point type and | |
1718 | all functions also exist in a reentrant form. | |
342414a6 RM |
1719 | |
1720 | * The new auxiliary library `-lutil' from 4.4 BSD contains various | |
1721 | functions for maintaining the login-record files (primarily of use to | |
1722 | system programs such as `login'), and convenient functions for | |
1723 | allocating and initializing a pseudo-terminal (pty) device. | |
c709e372 RM |
1724 | |
1725 | * Ulrich Drepper has contributed new support for System V style | |
1726 | shared memory and IPC on systems that support it. | |
1727 | ||
1728 | * Ulrich Drepper has contributed several miscellaneous new functions found | |
1729 | in System V: The `hsearch' family of functions provide an effective | |
1730 | implementation of hash tables; `a64l' and `l64a' provide a very simple | |
1731 | binary to ASCII mapping; `drand48' and friends provide a 48-bit random | |
1732 | number generator. | |
1733 | ||
1734 | * Ulrich Drepper has contributed new reentrant counterparts for the | |
1735 | `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. | |
1736 | ||
1737 | * Ulrich Drepper has contributed new, highly-optimized versions of several | |
1738 | string functions for the i486/Pentium family of processors. | |
1739 | ||
71733723 | 1740 | * Ulrich Drepper has updated the Linux-specific code, based largely |
c709e372 | 1741 | on work done in Hongjiu Lu's version of GNU libc for Linux. |
33a934a3 UD |
1742 | The GNU library now supports Linux versions 2.0.10 and later, |
1743 | using the ELF object file format (i[3456]86-*-linux). | |
c709e372 | 1744 | |
d3669add RM |
1745 | * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). |
1746 | ||
33a934a3 UD |
1747 | * David Mosberger-Tang and Richard Henderson have ported the C library |
1748 | to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the | |
1749 | dynamic linking support for ELF/Alpha. | |
1750 | ||
1751 | * Richard Henderson contributed several Alpha optimized assembler function | |
1752 | for arithmetic and string handling. | |
d3669add | 1753 | |
c709e372 | 1754 | * Ulrich Drepper has contributed a new set of message catalog functions to |
40a4b79f RM |
1755 | support multiple languages using the <libintl.h> interface, for use with |
1756 | his new package GNU gettext. Translation volunteers have contributed | |
1757 | catalogs of the library's messages in Spanish, German, and Korean. | |
1758 | ||
1759 | * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' | |
1760 | program and the `catgets' function for reading the catalog files it | |
1761 | creates. (The <libintl.h> interface is preferred; we include the | |
1762 | <nl_types.h> interface using `catgets' only for source compatibility with | |
1763 | programs already written to use it.) | |
71733723 RM |
1764 | |
1765 | * New header file <values.h> gives SVID-compatible names for <limits.h> | |
1766 | constants. | |
1767 | ||
1768 | * Various new macros, declarations, and small header files for compatibility | |
1769 | with 4.4 BSD. | |
1770 | ||
1771 | * New function `group_member' is a convenient way to check if a process has | |
1772 | a given effective group ID. | |
1773 | ||
1774 | * When using GCC 2.7 and later, the socket functions are now declared in a | |
1775 | special way so that passing an argument of type `struct sockaddr_in *', | |
1776 | `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic | |
1777 | `struct sockaddr *' type, does not generate a type-clash warning. | |
1778 | ||
1779 | * New function `error' declared in header file <error.h> is a convenient | |
6d52618b | 1780 | function for printing error messages and optionally exiting; this is the |
71733723 RM |
1781 | canonical function used in GNU programs. The new functions `err', `warn', |
1782 | and friends in header file <err.h> are the canonical 4.4 BSD interface for | |
1783 | doing the same thing. | |
1784 | ||
1785 | * The <glob.h> interface has several new flags from 4.4 BSD that extend the | |
1786 | POSIX.2 `glob' function to do ~ and {...} expansion. | |
1787 | ||
1788 | * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. | |
33a934a3 | 1789 | `clearenv' which is used in POSIX.9 is also available. |
71733723 RM |
1790 | |
1791 | * New function `getsid' returns session ID number on systems that support it. | |
1792 | ||
f7eac6eb RM |
1793 | * We have incorporated the 4.4 BSD `db' library (version 1.85). New header |
1794 | files <db.h> and <mpool.h> provide a rich set of functions for several | |
1795 | types of simple databases stored in memory and in files, and <ndbm.h> is | |
6d52618b | 1796 | an old `ndbm'-compatible interface using the `db' functions. Link with |
999493cb | 1797 | `-ldb' to get these functions. |
f7eac6eb RM |
1798 | |
1799 | * New macro `strdupa' copies a string like `strdup', but uses local stack | |
1800 | space from `alloca' instead of dynamic heap space from `malloc'. | |
52e9a9d1 RM |
1801 | |
1802 | * New function `strnlen' is like `strlen' but searches only a given maximum | |
33a934a3 UD |
1803 | number of characters for the null terminator. `stpncpy', `strndup' and |
1804 | `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' | |
1805 | function. | |
40a4b79f RM |
1806 | |
1807 | * New function `statfs' in header <sys/statfs.h>. | |
1808 | ||
1809 | * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader | |
1810 | provide convenient functions for operating on blocks of null-terminated | |
1811 | strings. | |
1812 | ||
1813 | * A new suite of functions in <utmp.h> handle all the details of reading | |
1814 | and writing the utmp file. | |
33a934a3 UD |
1815 | |
1816 | * An implementation of the NIS/YP(tm) based NSS service was contributed by | |
1817 | Thorsten Kukuk. | |
1818 | ||
1819 | * Paul Eggert and Ulrich Drepper modified the `strftime' function to be | |
1820 | completely POSIX compliant and also implemented the extended functionality | |
1821 | to handle alternate digit representation and alternate era date formats. | |
1822 | ||
1823 | * Ulrich Drepper provided an implementation of the `strptime' function | |
1824 | defined in XPG4.2 which transforms a string into a `struct tm' value. | |
1825 | ||
1826 | * Paul Eggert provided the tzselect shell script as part of the timezone | |
1827 | code. The shell script makes it easy to select the correct timezone | |
1828 | specification. | |
1829 | ||
1830 | * The implementation of the malloc family of functions is completely replaced | |
1831 | by a new implementation by Doug Lea with many improvements by Wolfram Gloger. | |
1832 | The implementation uses the mmap function (if available) and it is | |
1833 | optimized for the use in multi threaded programs. | |
1834 | ||
1835 | * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of | |
1836 | functions. This new functionality is usable by specifying a special | |
1837 | salt string and it is compatible with implementation on *BSD systems. | |
1838 | ||
1839 | * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: | |
1840 | `getsubopt' to handle second level command line options, `bsd_signal' | |
1841 | to access BSD style `signal' functionality, the obsolete `regexp' style | |
1842 | expression matcher. | |
1843 | ||
1844 | * the `lchown' function is available on system which support this | |
1845 | functionality. | |
1846 | ||
1847 | * The implementation of the shadow password handling function was contributed | |
1848 | by Ulrich Drepper. | |
1849 | ||
1850 | * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. | |
1851 | ||
1852 | * POSIX.1g support was added. The <sys/select.h> header is available, | |
1853 | `isfdtype' and `pselect' are implemented. Craig Metz contributed an | |
1854 | implementation of `getaddrinfo'. | |
28f540f4 RM |
1855 | \f |
1856 | Version 1.09 | |
1857 | ||
1858 | * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. | |
1859 | ||
1860 | * New header file <fstab.h> and new functions `getfsspec', `getfsent' and | |
1861 | friends, for parsing /etc/fstab. This code comes from 4.4 BSD. | |
1862 | ||
1863 | * The new function `daemon' from 4.4 BSD is useful for server programs that | |
1864 | want to put themselves in the background. | |
1865 | ||
1866 | * Joel Sherrill has contributed support for several standalone boards that | |
1867 | run without an operating system. | |
1868 | ||
1869 | * `printf', `scanf' and friends now accept a `q' type modifier for long | |
1870 | long int as well as `ll'. Formats using these might be `%qu' or `%lld'. | |
1871 | ||
1872 | * All of the code taken from BSD (notably most of the math and networking | |
1873 | routines) has been updated from the BSD 4.4-Lite release. | |
1874 | ||
1875 | * The resolver code has been updated from the BIND-4.9.3-BETA9 release. | |
1876 | ||
1877 | * The new functions `getdomainname' and `setdomainname' fetch or change the | |
1878 | YP/NIS domain name. These are system calls which exist on systems which | |
1879 | have YP (aka NIS). | |
1880 | ||
1881 | * The time zone data files have been updated for the latest international | |
1882 | conventions. | |
1883 | ||
1884 | * The SunRPC programs `portmap' and `rpcinfo' are now installed in | |
1885 | $(sbindir) (usually /usr/local/sbin) instead of $(bindir). | |
1886 | \f | |
1887 | Version 1.08 | |
1888 | ||
1889 | * The C library now includes support for Sun RPC, from Sun's free | |
1890 | RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs | |
1891 | are included. (There is still no support for YP.) | |
1892 | ||
1893 | * Tom Quinn has contributed a port of the C library to SGI machines running | |
1894 | Irix 4 (mips-sgi-irix4). | |
1895 | ||
1896 | * The new `lockf' function is a simplified interface to the locking | |
1897 | facilities of `fcntl', included for compatibility. | |
1898 | ||
1899 | * New time functions `timegm', `timelocal', and `dysize' for compatibility. | |
1900 | ||
1901 | * New header file <sys/timeb.h> and new function `ftime' for compatibility. | |
1902 | ||
1903 | * New header files <poll.h> and <sys/poll.h> and new function `poll' for | |
1904 | compatibility. | |
1905 | ||
1906 | * The error message printed by `assert' for a failed assertion now includes | |
1907 | the name of the program (if using GNU ld) and the name of the calling | |
1908 | function (with versions of GCC that support this). | |
1909 | ||
1910 | * The `psignal' function is now declared in <signal.h>, not <stdio.h>. | |
1911 | ||
1912 | * The library now includes the <sys/mman.h> header file and memory | |
1913 | management functions `mmap', `munmap', `mprotect', `msync', and | |
1914 | `madvise', on systems that support those facilities. | |
1915 | ||
1916 | * The interface for `mcheck' has changed slightly: the function called to | |
1917 | abort the program when an allocation inconsistency is detected now takes | |
1918 | an argument that indicates the type of failure. The new function | |
1919 | `mprobe' lets you request a consistency check for a particular block at | |
1920 | any time (checks are normally done only when you call `free' or `realloc' | |
1921 | on a block). | |
1922 | ||
1923 | * It is now possible to easily cross-compile the C library, building on one | |
1924 | system a library to run on another machine and/or operating system. All | |
1925 | you need to do is set the variable `HOST_CC' in `configparms' to the | |
1926 | native compiler for programs to run on the machine you are building on (a | |
1927 | few generator programs are used on Unix systems); set `CC' to the | |
1928 | cross-compiler. | |
1929 | ||
1930 | * The new function `fexecve' (only implemented on the GNU system) executes | |
1931 | a program file given a file descriptor already open on the file. | |
1932 | \f | |
1933 | Version 1.07 | |
1934 | ||
1935 | * Brendan Kehoe has contributed most of a port to the DEC Alpha | |
1936 | running OSF/1 (alpha-dec-osf1). He says it is 75% complete. | |
1937 | ||
1938 | * You can set the variable `libprefix' in `configparms' to specify a prefix | |
1939 | to be prepended to installed library files; this makes it easy to install | |
1940 | the GNU C library to be linked as `-lgnuc' or whatever. | |
1941 | ||
1942 | * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It | |
1943 | copies a limited number of characters from a string, and returns the | |
1944 | address of the last character written. | |
1945 | ||
1946 | * You no longer need to check for whether the installed `stddef.h' is | |
1947 | compatible with the GNU C library. configure now checks for you. | |
1948 | ||
1949 | * You can now define a per-stream `fileno' function to convert the | |
1950 | stream's cookie into an integral file descriptor. | |
1951 | ||
1952 | * ``malloc (0)'' no longer returns a null pointer. Instead, it | |
1953 | allocates zero bytes of storage, and returns a unique pointer which | |
1954 | you can pass to `realloc' or `free'. The behavior is undefined if | |
1955 | you dereference this pointer. | |
1956 | ||
1957 | * The C library now runs on Sony NEWS m68k machines running either | |
1958 | NewsOS 3 or NewsOS 4. | |
1959 | ||
1960 | * The new `syscall' function is a system-dependent primitive function | |
1961 | for invoking system calls. It has the canonical behavior on Unix | |
1962 | systems, including unreliable return values for some calls (such as | |
1963 | `pipe', `fork' and `getppid'). | |
1964 | ||
1965 | * The error code `EWOULDBLOCK' is now obsolete; it is always defined | |
1966 | to `EAGAIN', which is the preferred name. On systems whose kernels | |
1967 | use two distinct codes, the C library now translates EWOULDBLOCK to | |
1968 | EAGAIN in every system call function. | |
1969 | \f | |
1970 | Version 1.06 | |
1971 | ||
1972 | * The GNU C Library Reference Manual is now distributed with the library. | |
1973 | `make dvi' will produce a DVI file of the printed manual. | |
1974 | `make info' will produce Info files that you can read on line using C-h i | |
1975 | in Emacs or the `info' program. | |
ea278354 | 1976 | Please send comments on the manual to bug-glibc-manual@gnu.org. |
28f540f4 RM |
1977 | |
1978 | * The library now supports SVR4 on i386s (i386-unknown-sysv4). | |
1979 | ||
1980 | * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. | |
1981 | ||
1982 | * Jason Merrill has contributed a port to the Sequent Symmetry running | |
1983 | Dynix version 3 (i386-sequent-dynix). | |
1984 | ||
1985 | * The library has been ported to i386s running SCO 3.2.4 (also known as SCO | |
1986 | ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). | |
1987 | ||
1988 | * New function `memory_warnings' lets you arrange to get warnings when | |
1989 | malloc is running out of memory to allocate, like Emacs gives you. | |
1990 | ||
1991 | * The C library now contains the relocating allocator used in Emacs 19 for | |
1992 | its editing buffers. This allocator (ralloc) minimizes allocation | |
1993 | overhead and fragmentation by moving allocated regions around whenever it | |
1994 | needs to. You always refer to a ralloc'd region with a "handle" (a | |
1995 | pointer to a pointer--an object of type `void **'). | |
1996 | ||
1997 | * There is a new `printf' format: `%m' gives you the string corresponding | |
1998 | to the error code in `errno'. | |
1999 | ||
2000 | * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' | |
2001 | or `%[' conversion, but instead of filling in a fixed-sized buffer you | |
2002 | pass, the `a' modifier says to fill in a `char **' you pass with a | |
2003 | malloc'd string. | |
2004 | ||
2005 | * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and | |
2006 | `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a | |
2007 | name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. | |
2008 | ||
2009 | * `mkstemp' is a traditional Unix function to atomically create and open a | |
2010 | uniquely-named temporary file. | |
2011 | \f | |
2012 | Version 1.05 | |
2013 | ||
2014 | * The standard location for the file that says what the local timezone is | |
2015 | has changed again. It is now `/usr/local/etc/localtime' (or more | |
2016 | precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. | |
2017 | ||
2018 | * The distribution no longer contains any files with names longer than 14 | |
2019 | characters. | |
2020 | ||
2021 | * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. | |
2022 | These are set by the new `trusted' and `console' keywords in `/etc/ttys'. | |
2023 | ||
2024 | * New functions `ttyslot' and `syslog' from 4.4 BSD. | |
2025 | \f | |
2026 | Version 1.04 | |
2027 | ||
2028 | * The configuration process has changed quite a bit. The `configure' | |
2029 | script is now used just like the configuration scripts for other GNU | |
2030 | packages. The `sysdeps' directory hierarchy is much rearranged. | |
2031 | The file `INSTALL' explains the new scheme in detail. | |
2032 | ||
2033 | * The header files no longer need to be processed into ANSI C and | |
2034 | traditional C versions. There is just one set of files to install, and | |
2035 | it will work with ANSI or old C compilers (including `gcc -traditional'). | |
2036 | ||
2037 | * Brendan Kehoe and Ian Lance Taylor have ported the library to the | |
2038 | MIPS DECStation running Ultrix 4. | |
2039 | ||
2040 | * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. | |
2041 | Tom Quinn contributed the initial code. The GNU C library can NOT yet be | |
2042 | made itself into a shared library. | |
2043 | ||
2044 | * Yet further improved support for the i386, running 4.3 BSD-like systems | |
2045 | (such as Mach 3 with the Unix single-server), or System V. | |
2046 | ||
2047 | * New function `strncasecmp' to do case-insensitive string comparison | |
2048 | with limited length. | |
2049 | ||
2050 | * New function `strsep' is a reentrant alternative to `strtok'. | |
2051 | ||
2052 | * New functions `scandir' and `alphasort' for searching directories. | |
2053 | ||
2054 | * New function `setenv' is a better interface to `putenv'. | |
2055 | ||
2056 | * Ian Lance Taylor has contributed an implementation of the SVID `ftw' | |
2057 | function for traversing a directory tree. | |
2058 | ||
2059 | * The GNU obstack package is now also part of the C library. | |
2060 | The new function `open_obstack_stream' creates a stdio stream that | |
2061 | writes onto an obstack; `obstack_printf' and `obstack_vprintf' do | |
2062 | formatted output directly to an obstack. | |
2063 | ||
2064 | * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), | |
2065 | cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. | |
2066 | ||
2067 | * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. | |
2068 | ||
2069 | * The new functions `strfry' and `memfrob' do mysterious and wonderful | |
2070 | things to your strings. | |
2071 | ||
2072 | * There are some new test programs: test-fseek, testmb, and testrand. | |
2073 | ||
2074 | * Some work has been done to begin porting the library to 4.4 BSD and Linux. | |
2075 | These ports are not finished, but are a good starting place for really | |
2076 | supporting those systems. | |
2077 | ||
2078 | * `/etc/localtime' is now the standard location for the file that says what | |
2079 | the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. | |
2080 | This follows the general principle that `/etc' is the place for all local | |
2081 | configuration files. | |
2082 | ||
2083 | * The C library header files now use `extern "C"' when used by the C++ | |
2084 | compiler, so the C library should now work with C++ code. | |
2085 | ||
2086 | * The header file <bstring.h> is gone. <string.h> now declares bcopy, | |
56ddf355 UD |
2087 | bcmp, bzero, and ffs. (Update: nowadays these functions are declared |
2088 | in <strings.h>.) | |
28f540f4 RM |
2089 | |
2090 | * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting | |
2091 | function which uses the `merge sort' algorithm, and is said to be | |
2092 | significantly faster than the old GNU `qsort' function. Merge sort is | |
2093 | now the standard `qsort' function. The new algorithm can require a lot | |
2094 | of temporary storage; so, the old sorting function is called when the | |
2095 | required storage is not available. | |
2096 | ||
2097 | * The C library now includes Michael Glad's Ultra Fast Crypt, which | |
2098 | provides the Unix `crypt' function, plus some other entry points. | |
28f540f4 RM |
2099 | |
2100 | * The code and header files taken from 4.4 BSD have been updated with the | |
2101 | latest files released from Berkeley. | |
