Important general notes
-----------------------
Date Modules Changes
2025-09-03 gnulib-tool If you use --makefile-name with --with-tests, you
now need to initialize AM_CFLAGS before the
'include <gnulib-generated-makefile>' statement.
2022-07-24 bootstrap To specify a reference directory for the 'gnulib'
submodule, use the environment variable
GNULIB_REFDIR instead of GNULIB_SRCDIR or the
command-line option --gnulib-refdir instead of
--gnulib-srcdir.
2022-02-20 (all) Automake >= 1.14 and Autoconf >= 2.64 are required.
2021-06-04 (all) The license notices in source files are now really
stating the effective license, rather than a fake
GPL notice.
gnulib-tool no longer replaces GPL notices in source
files by something else.
2020-08-16 (all) Automake >= 1.11 and Autoconf >= 2.64 are required.
2019-12-11 Support for These modules are now supported in C++ mode as well.
ISO C or POSIX This means, while the autoconfiguration uses the C
functions compiler, the resulting header files and function
substitutes can be used with a matching C++ compiler
as well.
2019-02-14 gnulib-tool If you use multiple --local-dir options at once:
The first one now has the highest priority, not the
last one.
2019-01-04 (all) The meaning of the 'Link' section in the module
descriptions has been clarified: It overrides the
combined 'Link' sections from the dependencies.
2018-10-22 (all) Automake >= 1.11 and Autoconf >= 2.63 are required.
2016-09-05 progname There is now an alternate module 'getprogname'. It
defines a getprogname() function; use it to obtain
the name of the current program.
Recommended use:
- In a program's main() function, and associated
usage() and help() functions, use 'progname'.
- In library code, or more generally any code that
is not near the main() function, use
'getprogname'.
2013-04-24 gettext If your project uses 'gettextize --intl' it is now
your responsibility to put -I$(top_builddir)/intl
into the Makefile.am for gnulib.
2012-06-27 elisp-comp The module 'elisp-comp' is removed; the script is
not independently useful outside of automake.
2012-06-21 gnulib-tool The option --with-tests is now implied by the
options --create-testdir, --test,
--create-megatestdir, --megatest.
2012-01-07 quotearg In the C locale, the function will no longer use
the grave accent character to begin a quoted
string (`like this'). It will use apostrophes
'like these' or, in Unicode locales, single quotes
‘like these’. You may want to adjust any error
messages that hard code the quoting characters.
2010-09-04 gnulib-tool The option '--import' is no longer cumulative; it
now expects the complete list of modules and other
options on the command line. If you want to
augment (not set) the list of modules, use the
new option '--add-import' instead of '--import'.
User visible incompatible changes
---------------------------------
Date Modules Changes
2026-02-21 streq This module is renamed to 'streq-opt'. Its include
file is renamed from "streq.h" to "streq-opt.h".
2025-12-04 issymlinkat The include file is changed from "issymlink.h" to
"issymlinkat.h".
2025-11-01 nstrftime The return type is now signed not size_t,
c-nstrftime the failure return value is now -1 not 0,
fprintftime and errno is no longer preserved on success.
The return type is now off64_t for fprintftime,
ptrdiff_t for the others.
2025-08-05 git-merge-changelog This module is removed. Use the package from
https://git.savannah.gnu.org/git/vc-changelog.git
instead.
2025-07-13 safe-alloc This module is now obsolete. Also, it no longer
defines the REALLOC_N macro.
2025-05-09 string-desc These modules now distinguish between read-only
xstring-desc string descriptors (type string_desc_t) and
writable string descriptors (type rw_string_desc_t).
2025-05-09 copy-acl The mode_t arguments of qcopy_acl and xcopy_acl
qcopy-acl should be the full st_mode of the source,
not merely st_mode's permission bits.
2025-04-29 hash-triple-simple This module is renamed to hashcode-named-file.
2025-01-02 string-desc The function prefix is changed from string_desc_
xstring-desc to sd_, and from xstring_desc_ to xsd_.
string-desc-quotearg

instead of an 'int'.
2024-11-05 eealloc This module is deprecated. Use malloc-gnu or
realloc-posix instead.
2024-10-22 spawn-pipe The functions 'create_pipe_out', 'create_pipe_in',
'create_pipe_bidi' now take a 4th argument
'const char * const *dll_dirs'. To maintain the
previous behaviour, insert NULL as additional 4th
argument.
2024-10-22 execute The function 'execute' now takes a 4th argument
'const char * const *dll_dirs'. To maintain the
previous behaviour, insert NULL as additional 4th
argument.
2024-10-02 file-has-acl The file_has_aclinfo function introduced 3 days ago
now has a different signature.
2024-09-25 string-buffer The function sb_append is renamed to sb_append_c.
The function sb_dupfree is renamed to sb_dupfree_c.
2024-08-14 verror The include file is changed from "verror.h"
to <error.h>.
2024-08-09 full-read These modules now prefer signed types to size_t.
full-write The preferred types are idx_t for object sizes and
safe-read ptrdiff_t for values that are either a size or -1.
safe-write SAFE_READ_ERROR and SAFE_WRITE_ERROR are now
obsolescent; callers can just check for < 0.
2024-06-22 xvasprintf It is now the programmer's responsibility to pass
c-xvasprintf a valid format string without %ls, %lc directives
and that all widths are >= -INT_MAX and <= INT_MAX.
2024-05-16 putenv This module is renamed to 'putenv-gnu'.
2024-02-21 *printf-posix These modules no longer support the 'n' directive
by default. In order to keep the 'n' directive
enabled, you need to additionally request the
module 'printf-with-n-directive'.
2024-02-09 strftime This module, deprecated on 2017-07-23, is removed.
Use module 'nstrftime' instead.
2023-09-03 same-inode SAME_INODE, ST_BLKSIZE and ST_NBLOCKS args
stat-size must be addressable lvalues.
2023-08-08 readutmp The result element type of the function read_utmp,
STRUCT_UTMP, is no longer the same as the result
value type of the function getutxent, struct utmpx.
2023-08-03 readutmp Some STRUCT_UTMP members can be char *,
2023-08-01 rather than fixed-length char arrays.
On some platforms, the timestamp is ut_ts of type
struct timespec, not ut_tv of type struct timeval,
and ut_session is pid_t not long.
read_utmp's 2nd arg is now idx_t * not size_t *.
Link additionally with $(READUTMP_LIB).
2023-07-10 dfa The signature of the function
case_folded_counterparts, declared in localeinfo.h,
has changed.
2023-06-10 javacomp-script These modules now compile the Java code with option
javacomp '-source 1.6' or higher. As a consequence, the
compiler may emit notes "... uses unchecked or
unsafe operations". To avoid these notes, add
template arguments to the types or functions.
2023-04-28 largefile-required
year2038-required
Modules removed, for consistency with Autoconf
master. Use new module year2038-recommended
instead of year2038-required.
2023-03-25 mtx This module no longer provides the function
call_once. To get this function, use the new
separate module 'call_once'.
2023-03-08 time This module is renamed to 'time-h'.

$(LIB_POSIX_SPAWN).
2023-01-07 poll Link with $(POLL_LIB) instead of $(LIB_POLL).
2023-01-07 nanosleep Link with $(NANOSLEEP_LIB) instead of

$(LIB_CLOCK_GETTIME).
2023-01-06 file-has-acl Link with $(FILE_HAS_ACL_LIB), not $(LIB_HAS_ACL).
2022-12-25 largefile configure no longer enables year-2038 support,
unless you configure with --enable-year2038
or use the year2038 module. This temporary
hack should go away before the year 2038.
2022-12-24 stdnoreturn This module is deprecated. Use _Noreturn
or the noreturn module instead.
2022-12-21 ctime This module is deprecated. Use localtime_r
and strftime (or even sprintf) instead.
2022-11-03 dynarray These modules are renamed to glibc-internal/dynarray

They are not meant for general use.
2022-11-02 scratch_buffer The function 'gl_scratch_buffer_dupfree' is removed.
2022-09-10 stdbool This module now assumes C99 and provides C23,
instead of providing C99. For the old behavior,
use the already-deprecated stdbool-c99 module.

2022-01-05 stack This module now uses idx_t instead of size_t
for indexes and counts.
2021-08-27 base32 These modules now use idx_t instead of size_t
base64 for indexes and counts.
2021-07-29 (all) Due to draft C2x, the following attributes should
now appear at the start of a function declaration:
_GL_ATTRIBUTE_DEPRECATED
_GL_ATTRIBUTE_MAYBE_UNUSED
_GL_ATTRIBUTE_NODISCARD
attribute Likewise for DEPRECATED, MAYBE_UNUSED, NODISCARD.
snippet/unused-parameter
Likewise for _GL_UNUSED_PARAMETER.
2021-07-01 largefile AC_SYS_LARGEFILE now also arranges for time_t
to be 64-bit on 32-bit GNU/Linux platforms
that support it (glibc 2.34 or later).
2021-03-21 fatal-signal The function at_fatal_signal now returns an error
indicator.
2021-03-21 diacrit This deprecated module is removed.
2021-03-07 mbrtowc For single-locale optimizations, you now need to
mbrtoc32 define GNULIB_WCHAR_SINGLE_LOCALE instead of
wcwidth GNULIB_WCHAR_SINGLE.
2021-02-28 parse-datetime The parse_datetime2 function has been moved
to the new parse-datetime2 module, so that
programs that need just parse_datetime need
not build the fancier function.
2020-12-23 execute These functions no longer execute scripts without
spawn-pipe '#!' marker through /bin/sh. To execute such a
posix_spawn script as a shell script, either add a '#!/bin/sh'
posix_spawnp marker in the first line, or specify "/bin/sh" as
the program to execute and the script as its first
argument.
2020-12-18 free This module, obsoleted in 2008, is gone.
2020-12-14 findprog-in The function 'find_in_given_path' now takes a 3rd
argument 'const char *directory'. To maintain the
previous behaviour, insert NULL as additional 3rd
argument.
2020-12-11 sh-quote The argv argument of the 'shell_quote_argv' function
is now of type 'const char * const *'. You no
longer need to cast read-only strings to 'char *'
when constructing this argument.
execute The prog_argv argument of the 'execute' function
is now of type 'const char * const *'. You no
longer need to cast read-only strings to 'char *'
when constructing this argument.
spawn-pipe The prog_argv argument of the functions
'create_pipe_out', 'create_pipe_in',
'create_pipe_bidi' is now of type
'const char * const *'. You no longer need to cast
read-only strings to 'char *' when constructing this
argument.
pipe-filter-gi The prog_argv argument of the
'pipe_filter_gi_create' function is now of type
'const char * const *'. You no longer need to cast
read-only strings to 'char *' when constructing this
argument.
pipe-filter-ii The prog_argv argument of the
'pipe_filter_ii_execute' function is now of type
'const char * const *'. You no longer need to cast
read-only strings to 'char *' when constructing this
argument.
javaexec The prog_argv argument of the 'execute_fn' function
type is now of type 'const char * const *'. Update
the signature of all your implementations of this
type.
csharpexec The prog_argv argument of the 'execute_fn' function
type is now of type 'const char * const *'. Update
the signature of all your implementations of this
type.
2020-12-02 spawn-pipe The functions 'create_pipe_out', 'create_pipe_in',
'create_pipe_bidi' now take a 4th argument
'const char *directory'. To maintain the previous
behaviour, insert NULL as additional 4th argument.
2020-12-02 execute The function 'execute' now takes a 4th argument
'const char *directory'. To maintain the previous
behaviour, insert NULL as additional 4th argument.
2020-10-16 hash This module deprecates the 'hash_delete' function
using gcc's "deprecated" attribute. Use the better-
named 'hash_remove' equivalent.
2020-08-24 diffseq If you do not define NOTE_ORDERED to true,
the NOTE_DELETE and NOTE_INSERT actions might
not be done in order, to help cut down worst-case
recursion stack space from O(N) to O(log N).
2020-08-01 libtextstyle-optional You now need to invoke
gl_LIBTEXTSTYLE_OPTIONAL explicitly, because
this macro now takes an optional
MINIMUM-VERSION argument.
2020-08-01 libtextstyle You now need to invoke gl_LIBTEXTSTYLE explicitly,
because this macro now takes an optional
MINIMUM-VERSION argument.
2020-06-27 clean-temp The functions open_temp, fopen_temp now take a
'bool delete_on_close' argument. If in doubt, pass
false.
2020-06-27 tempname The link requirements of these modules are changed
mkdtemp from empty to $(LIB_GETRANDOM).
mkstemp
mkstemps
mkostemp
mkostemps
tmpfile
stdlib-safer
tmpfile-safer
clean-temp
javacomp $(LIB_GETRANDOM) was added to the link requirements
of this module.
2020-05-27 read-file The functions provided by this module now take an
'int flags' argument to modify the file reading
behavior. The read_binary_file function has been
removed as it is no longer necessary.
2020-04-27 getdate This deprecated module is removed. Use the module
'parse-datetime' instead. Instead of
#include "getdate.h"
write
#include "parse-datetime.h"
The function get_date is renamed to parse_datetime.
2020-04-27 realloc This deprecated module is removed. Use the module
'realloc-gnu' instead.
2020-04-27 calloc This deprecated module is removed. Use the module

'spawn-pipe' instead. Instead of
#include "pipe.h"
write
#include "spawn-pipe.h"
2020-04-27 getopt This deprecated module is removed. Please choose
among getopt-posix and getopt-gnu. getopt-gnu
provides "long options" and "options with optional
arguments", getopt-posix doesn't.
2020-04-27 rename-dest-slash This deprecated module is removed. Use the
module 'rename' instead.
2020-04-27 unictype/bidicategory-* These deprecated modules are removed. Use
the modules unictype/bidiclass-* instead.

2020-03-28 filename The macro IS_ABSOLUTE_PATH is deprecated. Use
IS_ABSOLUTE_FILE_NAME instead.
The macro IS_PATH_WITH_DIR is deprecated. Use
IS_FILE_NAME_WITH_DIR instead.
2020-02-22 fchownat This module no longer defines the functions
'chownat' and 'lchownat'. Program that need these
functions should add the module 'chownat' to the
list of imported modules.
2020-02-22 fchmodat This module no longer defines the functions
'chmodat' and 'lchmodat'. Program that need these
functions should add the module 'chmodat' to the
list of imported modules.
2020-02-07 fchmodat When applied to non-symlinks, these now act like
lchmod chmod (the BSD behavior, which POSIX requires for
fchmodat + AT_SYMLINK_NOFOLLOW), instead of failing
(the GNU/Linux behavior through glibc 2.31).
Future versions of GNU/Linux are planned to act as
per POSIX and BSD.
2020-01-15 gc-pbkdf2-sha1 This module is deprecated. Use gc-pbkdf2 instead.
2019-12-12 dfa Its API now uses ptrdiff_t instead of size_t.
2019-12-11 dfa To call dfamust, one must now call dfaparse
without yet calling dfacomp. This fixes a bug
introduced on 2018-10-22 that broke dfamust.
2019-12-07 xstrtol This module no longer defines the function
xstrtoll 'xstrtol_fatal'. Program that need this function
xstrtoimax should add the module 'xstrtol-error' to the list
xstrtoumax of imported modules.
2019-05-90 verify verify_true (deprecated 2011-06-15) is removed.
2019-03-16 fatal-signal The function that you pass to at_fatal_signal now
takes the signal as argument.
2019-02-02 c-strtod This and related modules no longer define
the HAVE_C99_STRTOLD macro. Programs requiring
standard strtold should use the strtold module.
2019-01-21 diacrit This module is deprecated. Please use the module
uninorm/canonical-decomposition instead.
2018-10-23 backupfile backup_file_rename and find_backup_file_name
now take an additional directory file descriptor
argument. Pass AT_FDCWD to get the old behavior.
2018-08-18 getpass The include file is changed from "getpass.h" to
getpass-gnu <unistd.h>.
2018-07-17 hard-locale m4/hard-locale.m4 and gl_HARD_LOCALE are removed.
2018-07-05 renameat2 This module is renamed to 'renameatu' and all
its include files and functions are renamed
accordingly.
2017-12-30 chdir-safer This module is removed. It was deprecated
on 2006-07-17.
2017-11-24 posixtm Previously, callers had to specify either
PDS_LEADING_YEAR or PDS_TRAILING_YEAR (but
not both). Now, callers should specify
only PDS_TRAILING_YEAR; leading years are
requested by not specifying PDS_TRAILING_YEAR.
2017-08-14 fcntl-h This module now defaults O_CLOEXEC to a nonzero
value instead of to 0, as the 'open' and
'openat' modules now emulate O_CLOEXEC.
2017-07-23 strftime This module is renamed to 'nstrftime'.
2017-05-19 closeout close_stdout longer closes stderr when addresses
are being sanitized, as the sanitizer outputs to
stderr afterwards.
2017-02-16 binary-io On MS-DOS and OS/2, set_binary_mode now fails
on ttys, and sets errno == EINVAL.
2017-01-20 parse-datetime The parse_datetime2 function now takes two
more arguments TZ and TZSTRING, for the
time zone and its name.
2017-01-16 host-cpu-c-abi On ARM platforms, HOST_CPU_C_ABI is now set to
'arm' or 'armhf' instead of 'armel'.
2017-01-15 localeinfo Change case_folded_counterparts's first arg's type
from wchar_t to wint_t, so it now accepts WEOF.
2016-12-17 getlogin The link requirements of these modules are changed
getlogin_r from empty to $(LIB_GETLOGIN).
2016-12-13 dfa Remove DFA_CASE_FOLD flag. Now based on RE_ICASE.
2016-11-17 unistr/u32-strmblen The function u32_strmblen can now return -1.
2016-11-17 unistr/u32-strmbtouc The function u32_strmbtouc can now return -1.
2016-08-17 stdbool This no longer supports _Bool for C++.
Programs intended to be portable to C++
compilers should use plain 'bool' instead.
2016-04-12 intprops The following macros were removed:
TYPE_TWOS_COMPLEMENT TYPE_ONES_COMPLEMENT
TYPE_SIGNED_MAGNITUDE
2015-09-25 c-ctype The following macros were removed:
C_CTYPE_CONSECUTIVE_DIGITS
C_CTYPE_CONSECUTIVE_LOWERCASE
C_CTYPE_CONSECUTIVE_UPPERCASE
2015-09-22 savewd SAVEWD_CHDIR_READABLE constant removed.
2015-07-24 fprintftime Exported functions' time zone arguments are now of
strftime type timezone_t (with NULL denoting UTC) instead of
type int (with nonzero denoting UTC). These
modules now depend on time_rz.
2015-04-24 acl This module no longer defines file_has_acl.
Use the new file-has-acl module for that.
Using only the latter module makes for fewer
link-time dependencies on GNU/Linux.
2015-04-15 acl If your project only uses the file_has_acl()
detection routine, then the requirements are
potentially reduced by using $LIB_HAS_ACL rather
than $LIB_ACL.
2015-04-03 hash hash_insert0 function removed (deprecated in 2011).
2014-10-29 obstack The obstack functions are no longer limited to
int sizes; size values are now of type size_t.
This changes both the ABI and the API.
obstack_blank no longer accepts a negative size to
shrink the current object; callers must now use
obstack_blank_fast with a "negative" (actually,
large positive) size for that.
2014-02-23 diffseq The members too_expensive, lo_minimal and hi_minimal
were removed from public structures, and the
find_minimal argument was removed from diag
and compareseq.
2014-02-11 savedir The savedir and streamsavedir functions have a
new argument specifying how to sort the result.
The fdsavedir function is removed.
2013-05-04 gnulib-tool CVS checkout of gnulib are no longer supported.
2013-02-08 careadlinkat This module no longer provides the careadlinkatcwd
function.
2012-06-26 getopt-posix This module no longer guarantees that option
processing is resettable. If your code uses
'optreset' or 'optind = 0;', rewrite it to make
only one pass over the argument array.
2012-02-24 streq This module no longer provides the STREQ macro.
Use STREQ_OPT instead.
2012-01-10 ignore-value This module no longer provides the ignore_ptr
function. It was deprecated a year ago, but existed
so briefly before then that it never came into use.
Now, the ignore_value function does its job.
2011-11-18 hash This module deprecates the hash_insert0 function
using gcc's "deprecated" attribute. Use the better-
named hash_insert_if_absent equivalent.
2011-11-04 openat This module no longer provides the mkdirat()
function. If you need this function, you now need
to request the 'mkdirat' module.
2011-11-04 openat This module no longer provides the fstatat()
function. If you need this function, you now need
to request the 'fstatat' module.
2011-11-03 openat This module no longer provides the unlinkat()
function. If you need this function, you now need
to request the 'unlinkat' module.
2011-11-02 openat This module no longer provides the fchmodat()
function. If you need this function, you now need
to request the 'fchmodat' module.
2011-11-01 alignof This module no longer provides the alignof() macro.
Use either alignof_slot() or alignof_type() instead.
2011-11-01 openat This module no longer provides the fchownat()
function. If you need this function, you now need
to request the 'fchownat' module.
2011-10-03 poll The link requirements of this module are changed
from empty to $(LIB_POLL).
2011-09-25 sys_stat This module no longer provides the fstat()
function. If you need this function, you now need
to request the 'fstat' module.
2011-09-23 signal This module is renamed to 'signal-h'.
2011-09-22 select The link requirements of this module are changed
from $(LIBSOCKET) to $(LIB_SELECT).
2011-09-12 fchdir This module no longer overrides the functions
opendir() and closedir(), unless the modules
'opendir' and 'closedir' are in use, respectively.
If you use opendir(), please use module 'opendir'.
If you use closedir(), please use module 'closedir'.
2011-08-04 pathmax The header file "pathmax.h" no longer defines
PATH_MAX on GNU/Hurd. Please use one of the methods
listed in pathmax.h to ensure your package is
portable to GNU/Hurd.
2011-07-24 close This module no longer pulls in the 'fclose' module.
If your code creates a socket descriptor using
socket() or accept(), then a FILE stream referring
to it using fdopen(), then in order to close this
stream, you need the 'fclose' module.
2011-07-12 arg-nonnull Renamed to snippet/arg-nonnull.
c++defs Renamed to snippet/c++defs.
link-warning Renamed to snippet/link-warning.
unused-parameter Renamed to snippet/unused-parameter.
warn-on-use Renamed to snippet/warn-on-use.
2011-06-15 verify verify_true (V) is deprecated; please use
verify_expr (V, 1) instead.
2011-06-05 ansi-c++-opt When a C++ compiler is not found, the variable CXX
is now set to "no", not to ":".
2011-05-11 group-member The include file is changed from "group-member.h"
to <unistd.h>.
2011-05-02 exit The module is removed. It was deprecated
on 2010-03-05. Use 'stdlib' directly instead.
2011-04-27 mgetgroups The 'xgetgroups' function has been split into
a new 'xgetgroups' module.
2011-04-27 save-cwd This module pulls in fewer dependencies by
default; to retain robust handling of directories
with an absolute name longer than PATH_MAX, you
must now explicitly include the 'getcwd' module.
2011-04-19 close-hook This module has been renamed to 'fd-hook' and
generalized.
2011-03-08 regex-quote The last argument is no longer an 'int cflags'
but instead a pointer to a previously constructed
'struct regex_quote_spec'.
2011-02-25 dirname These modules no longer put #defines for the
dirname-lgpl following symbols into <config.h>: ISSLASH,
backupfile FILE_SYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX,
lstat FILE_SYSTEM_BACKSLASH_IS_FILE_NAME_SEPARATOR,
openat FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE.
remove Applications that need ISSLASH can include the new
rmdir header dosname.h.
savewd
stat
unlink
2011-02-14 getloadavg This module no longer #defines C_GETLOADAVG or
HAVE_GETLOADAVG, as the application no longer needs
to worry about how getloadavg is defined. It no
longer defines the obsolete symbol NLIST_NAME_UNION
(which should have been internal to the module
anyway). Also, support for setgid use has been
removed, as nobody seems to be using it; thus
GETLOADAVG_PRIVILEGED is no longer #defined and
KMEM_GROUP and NEED_SETGID are no longer
substituted for.
2011-02-08 stdlib Unless the random_r module is also used, this
module no longer guarantees that the following are
defined: struct random_data, RAND_MAX, random_r,
srandom_r, initstate_r, setstate_r.
2011-02-08 wctype-h This module no longer provides the iswblank()
function. If you need this function, you now need
to request the 'iswblank' module.
2011-02-07 wctype This module is renamed to wctype-h.
2011-01-18 multiarch This no longer #defines AA_APPLE_UNIVERSAL_BUILD;
instead, use the shell var APPLE_UNIVERSAL_BUILD.
2010-12-10 pipe This module is renamed to spawn-pipe. The include
file is renamed to "spawn-pipe.h".
2010-10-05 getdate This module is deprecated. Please use the new
parse-datetime module for the replacement
function parse_datetime(), or help us write
getdate-posix for getdate(). Also, the header
"getdate.h" has been renamed "parse-datetime.h",
and doc/getdate.texi to doc/parse-datetime.texi.
2010-09-29 sys_wait This module no longer provides the waitpid()
function. If you need this function, you now need
to request the 'waitpid' module.
2010-09-17 utimens The function gl_futimens is removed, and its
signature has been migrated to fdutimens. Callers
of gl_futimens should change function name, and
callers of fdutimens should swap parameter order.
2010-09-17 fdutimensat This function has a new signature: the fd now comes
first instead of the dir/name pair, and a new
atflag parameter is added at the end. Old code
should rearrange parameters, and pass 0 for atflag.
2010-09-13 regex The module is not guaranteeing anymore support for
64-bit regoff_t on 64-bit systems. The size of
regoff_t will always be 32-bit unless the program
is being configured --with-included-regex. This
may change again in the future once glibc provides
this feature as well.
2010-09-12 savedir The fdsavedir function is now deprecated.
2010-09-10 fcntl-h This module now defaults O_CLOEXEC to 0, and
it defaults O_EXEC and O_SEARCH to O_RDONLY.
Use "#if O_CLOEXEC" instead of "#ifdef O_CLOEXEC".
2010-08-28 realloc This module is deprecated. Use 'realloc-gnu'
instead. It will be removed 2012-01-01.
2010-08-28 calloc This module is deprecated. Use 'calloc-gnu'
instead. It will be removed 2012-01-01.
2010-08-28 malloc This module is deprecated. Use 'malloc-gnu'
instead. It will be removed 2012-01-01.
2010-08-14 memxfrm This module is renamed to amemxfrm. The include
file is renamed to "amemxfrm.h". The function is
renamed to amemxfrm.
2010-08-09 symlinkat This module now only provides symlinkat; use the
new module 'readlinkat' if needed.
2010-07-31 ansi-c++-opt If Autoconf >= 2.66 is used, the 'configure'
option is now called --disable-c++ rather than
--disable-cxx.
2010-04-02 maintainer-makefile
The macro _prohibit_regexp has been revamped into
a new macro _sc_search_regexp; custom syntax
checks in your cfg.mk will need to be rewritten.
2010-03-28 lib-ignore This module now provides a variable
IGNORE_UNUSED_LIBRARIES_CFLAGS that you should
add to LDFLAGS (when linking C programs only) or
CFLAGS yourself. It is no longer added to LDFLAGS
automatically.
2010-03-18 pty This module now only declares the pty.h header.
Use the new modules 'forkpty' or 'openpty' to
get the functions that were previously provided.
2010-03-05 exit This module is deprecated, use 'stdlib' directly
instead. It will be removed 2011-01-01.
2009-12-13 sublist The module does not define functions any more that
call xalloc_die() in out-of-memory situations. Use
module 'xsublist' and include file "gl_xsublist.h"
instead.
2009-12-13 list The module does not define functions any more that
call xalloc_die() in out-of-memory situations.
Use module 'xlist' and include file "gl_xlist.h"
instead.
2009-12-13 oset The module does not define functions any more that
call xalloc_die() in out-of-memory situations.
Use module 'xoset' and include file "gl_xoset.h"
instead.
2009-12-10 * Most source code files have been converted to
indentation by spaces (rather than tabs). Patches
of gnulib source code needs to be updated.
2009-12-09 link-warning The Makefile rules that use $(LINK_WARNING_H) now
must contain an explicit dependency on
$(LINK_WARNING_H).
2009-11-12 getgroups These functions now use a signature of gid_t,
getugroups rather than GETGROUPS_T. This probably has no
effect except on very old platforms.
2009-11-04 tempname The gen_tempname function takes an additional
'suffixlen' argument. You can safely pass 0.
2009-11-04 nproc The num_processors function now takes an argument.
2009-11-02 inet_pton The use of this module now requires linking with
$(INET_PTON_LIB).
2009-11-02 inet_ntop The use of this module now requires linking with
$(INET_NTOP_LIB).
2009-10-10 utimens The use of this module now requires linking with
$(LIB_CLOCK_GETTIME).
2009-09-16 canonicalize-lgpl
The include file is changed from "canonicalize.h"
to <stdlib.h>.
2009-09-04 link-follow The macro LINK_FOLLOWS_SYMLINK is now tri-state,
rather than only defined to 1.
2009-09-03 openat The include files are standardized to POSIX 2008.
For openat, include <fcntl.h>; for
fchmodat, fstatat, and mkdirat, include
<sys/stat.h>; for fchownat and unlinkat,
include <unistd.h>. For all other
functions provided by this module,
continue to include "openat.h".
2009-08-30 striconveh The functions mem_cd_iconveh and str_cd_iconveh
now take an 'iconveh_t *' argument instead of three
iconv_t arguments.
2009-08-23 tempname The gen_tempname function takes an additional
'flags' argument. You can safely pass 0.
2009-08-12 getopt This module is deprecated. Please choose among
getopt-posix and getopt-gnu. getopt-gnu provides
"long options" and "options with optional
arguments", getopt-posix doesn't.
2009-06-25 fpurge The include file is changed from "fpurge.h" to
<stdio.h>.
2009-04-26 uniconv/u8-conv-from-enc
uniconv/u16-conv-from-enc
uniconv/u32-conv-from-enc
The calling convention of the functions
u*_conv_from_encoding is changed.
2009-04-26 uniconv/u8-conv-to-enc
uniconv/u16-conv-to-enc
uniconv/u32-conv-to-enc
The calling convention of the functions
u*_conv_to_encoding is changed.
2009-04-24 maintainer-makefile
The maint.mk file was copied from
coreutils, and the old
coverage/gettext/indent rules were
re-added. If you used 'make syntax-check'
this will add several new checks. If some
new check is annoying, add the name of the
checks to 'local-checks-to-skip' in your
cfg.mk.
2009-04-01 visibility Renamed to lib-symbol-visibility.
2009-04-01 ld-version-script Renamed to lib-symbol-versions.
2009-03-20 close The substituted variable LIB_CLOSE is removed.
2009-03-05 filevercmp Move hidden files up in ordering.
2009-01-22 c-strtod This function no longer calls xalloc_die(). If
c-strtold you want to exit the program in case of out-of-
memory, the calling function needs to arrange
for it, like this:
errno = 0;
val = c_strtod (...);
if (val == 0 && errno == ENOMEM)
xalloc_die ();
2009-01-17 relocatable-prog In the Makefile.am or Makefile.in, you now also
need to set RELOCATABLE_STRIP = :.
2008-12-22 getaddrinfo When using this module, you now need to link with
canon-host $(GETADDRINFO_LIB).
2008-12-21 mbiter The header files "mbiter.h", "mbuiter.h",
mbuiter "mbfile.h" can now be included without checking
mbfile HAVE_MBRTOWC. The macro HAVE_MBRTOWC will no
longer be defined by these modules in a year. If
you want to continue to use it, you need to invoke
AC_FUNC_MBRTOWC yourself.
2008-11-11 warnings This module subsumes the file m4/warning.m4 which
was removed.
2008-10-20 lstat The include file is changed from "lstat.h" to
<sys/stat.h>.
2008-10-20 getaddrinfo The include file is changed from "getaddrinfo.h"
to <netdb.h>.
2008-10-19 isnanf The include file is changed from "isnanf.h" to
<math.h>.
isnand The include file is changed from "isnand.h" to
<math.h>.
isnanl The include file is changed from "isnanl.h" to
<math.h>.
2008-10-18 lchmod The include file is changed from "lchmod.h" to
<sys/stat.h>.
2008-10-18 dirfd The include file is changed from "dirfd.h" to
<dirent.h>.
2008-10-18 euidaccess The include file is changed from "euidaccess.h"
to <unistd.h>.
2008-10-18 getdomainname The include file is changed from "getdomainname.h"
to <unistd.h>.
2008-09-28 sockets When using this module, you now need to link with
$(LIBSOCKET).
2008-09-24 sys_select The limitation on 'select', introduced 2008-09-23,
was removed. sys_select now includes a select
wrapper for Winsock. The wrapper expects socket
and file descriptors to be compatible as arranged
by the sys_socket on MinGW.
2008-09-23 sys_socket Under Windows (MinGW), the module now adds
wrappers around Winsock functions, so that
socket descriptors are now compatible with
file descriptors. In general, this change
will simply improve your code's portability
between POSIX platforms and Windows. In
particular, you will be able to use ioctl and
close instead of ioctlsocket and closesocket,
and test errno instead of WSAGetLastError ().
On the other hand, you have to audit your code to
remove usage of these Winsock-specific functions.
This change does not remove the need to call
the gl_sockets_startup function from the sockets
gnulib module. Also, for now select is disabled
when you include the sys_socket module; while
the functionality will be restored soon, for
efficiency it is suggested to use the poll system
poll system call and gnulib module instead.
2008-09-13 EOVERFLOW The module is removed. Use module errno instead.
2008-09-01 filename The module does not define the function
concatenated_filename any more. To get an
equivalent function, use function
xconcatenated_filename from module
'xconcat-filename'.
2008-08-31 havelib On Solaris, when searching for 64-bit mode
libraries the directory $prefix/lib is now ignored.
Instead the directory $prefix/lib/64 is searched.
You may need to create a symbolic link for
$prefix/lib/64 if you have 64-bit libraries
installed in $prefix/lib.
2008-08-19 strverscmp The include file is changed from "strverscmp.h"
to <string.h>.
2008-08-14 lock The include file is changed from "lock.h"
to "glthread/lock.h".
tls The include file is changed from "tls.h"
to "glthread/tls.h".
2008-07-17 c-stack The module now requires the addition of
$(LIBCSTACK) or $(LTLIBCSTACK) in Makefile.am,
since it may depend on linking with libsigsegv.
2008-07-07 isnanf-nolibm The include file is changed from "isnanf.h"
to "isnanf-nolibm.h".
isnand-nolibm The include file is changed from "isnand.h"
to "isnand-nolibm.h".
2008-06-10 execute The execute function takes an additional termsigp
argument. Passing termsigp = NULL is ok.
wait-process The wait_subprocess function takes an additional
termsigp argument. Passing termsigp = NULL is ok.
2008-05-10 linebreak The module is split into several modules unilbrk/*.
The include file is changed from "linebreak.h" to
"unilbrk.h". Two functions are renamed:
mbs_possible_linebreaks -> ulc_possible_linebreaks
mbs_width_linebreaks -> ulc_width_linebreaks
2008-04-28 rpmatch The include file is now <stdlib.h>.
2008-04-28 inet_ntop The include file is changed from "inet_ntop.h"
to <arpa/inet.h>.
2008-04-28 inet_pton The include file is changed from "inet_pton.h"
to <arpa/inet.h>.
2008-03-06 freadahead The return value's computation has changed. It
now increases by 1 after ungetc.
2008-01-26 isnan-nolibm The module name is changed from isnan-nolibm to
isnand-nolibm. The include file is changed from
"isnan.h" to "isnand.h". The function that it
defines is changed from isnan() to isnand().
2008-01-14 strcasestr This module now replaces worst-case inefficient
implementations; clients that use controlled
needles and thus do not care about worst-case
efficiency should use the new strcasestr-simple
module instead for smaller code size.
2008-01-09 alloca-opt Now defines HAVE_ALLOCA_H only when the system
supplies an <alloca.h>. Gnulib-using code is now
expected to include <alloca.h> unconditionally.
Non-gnulib-using code can continue to include
<alloca.h> only if HAVE_ALLOCA_H is defined.
2008-01-08 memmem This module now replaces worst-case inefficient
implementations; clients that use controlled
needles and thus do not care about worst-case
efficiency should use the new memmem-simple
module instead for smaller code size.
2007-12-24 setenv The include file is changed from "setenv.h" to
<stdlib.h>. Also, the unsetenv function is no
longer declared in this module; use the 'unsetenv'
module if you need it.
2007-12-03 getpagesize The include file is changed from "getpagesize.h"
to <unistd.h>.
2007-12-03 strcase The include file is changed from <string.h> to
<strings.h>.
2007-10-07 most modules The license for most modules has changed from
GPLv2+ to GPLv3+, and from LGPLv2+ to LGPLv3+.
A few modules are still under LGPLv2+; see the
module description for the applicable license.
2007-09-01 linebreak "linebreak.h" no longer declares the functions
locale_charset, uc_width, u{8,16,32}_width. Use
"uniwidth.h" to get these functions declared.
2007-08-28 areadlink-with-size
Renamed from mreadlink-with-size.
Function renamed: mreadlink_with_size ->
areadlink_with_size.
2007-08-22 getdelim, getline
The include file is changed from "getdelim.h"
and "getline.h" to the POSIX 200x <stdio.h>.
2007-08-18 idcache Now provides prototypes in "idcache.h".
2007-08-10 xstrtol The STRTOL_FATAL_ERROR macro is removed.
Use the new xstrtol_fatal function instead.
2007-08-04 human The function human_options no longer reports an
error to standard error; that is now the
caller's responsibility. It returns an
error code of type enum strtol_error
instead of the integer option value, and stores
the option value via a new int * argument.
xstrtol The first two arguments of STRTOL_FATAL_ERROR
are now an option name and option argument
instead of an option argument and a type string,
STRTOL_FAIL_WARN is removed.
2007-07-14 gpl, lgpl New Texinfo versions with no sectioning commands.
2007-07-10 version-etc Output now mentions GPLv3+, not GPLv2+. Use
gnulib-tool --local-dir to override this.
2007-07-07 wcwidth The include file is changed from "wcwidth.h" to
<wchar.h>.
2007-07-02 gpl, lgpl Renamed to gpl-2.0 and lgpl-2.1 respectively.
(There is also a new module gpl-3.0.)
2007-06-16 lchown The include file is changed from "lchown.h" to
<unistd.h>.
2007-06-09 xallocsa Renamed to xmalloca. The include file "xallocsa.h"
was renamed to "xmalloca.h". The function was
renamed:
xallocsa -> xmalloca
2007-06-09 allocsa Renamed to malloca. The include file "allocsa.h"
was renamed to "malloca.h". The function-like
macros were renamed:
allocsa -> malloca
freesa -> freea
2007-05-20 utimens Renamed futimens to gl_futimens, to avoid
conflict with the glibc-2.6-introduced function
that has a different signature.
2007-05-01 sigprocmask The module now depends on signal, so replace
#include "sigprocmask.h"
with
#include <signal.h>
2007-04-06 gettext The macro HAVE_LONG_DOUBLE is no longer set.
You can replace all its uses with 1, i.e. assume
'long double' as a type exists.

iconv_alloc -> str_cd_iconv (with reversed
arguments)
2007-03-15 list The functions gl_list_create_empty and
array-list gl_list_create now take an extra fourth argument.
carray-list You can pass NULL.

2007-03-12 des The types and functions in lib/des.h have been
gc-des renamed:
des_ctx -> gl_des_ctx, tripledes_ctx -> gl_3des_ctx,
des_is_weak_key -> gl_des_is_weak_key,

2007-02-28 xreadlink The module xreadlink was renamed to
xreadlink-with-size. The function was renamed:
xreadlink -> xreadlink_with_size.
2007-02-18 exit The modules now depend on stdlib, so replace
mkdtemp #include "exit.h"
mkstemp #include "mkdtemp.h"
#include "mkstemp.h"
with
#include <stdlib.h>
2007-01-26 strdup The module now depends on string, so replace
#include "strdup.h"
with
#include <string.h>
# This is for Emacs.
# Local Variables:
# coding: utf-8
# indent-tabs-mode: nil
# whitespace-check-buffer-indent: nil
# End:
