* renameatu: rename from renameat2Paul Eggert2018-07-051-0/+4
| | | | | | | | | | | | | | | | | | | | It's looking like Glibc will add a renameat2 function that is incompatible with Gnulib renameat2; see: https://sourceware.org/ml/libc-alpha/2018-07/msg00064.html To help avoid future confusion, rename renameat2 to something else. Use the name 'renameatu', as the Gnulib function is close to the Glibc function. Perhaps someday there will also be a renameat2 Gnulib module, which mimicks the future glibc renameat2, but that can wait as nobody seems to need such a module now. * NEWS: Mention this. * lib/renameatu.c: Rename from lib/renameat2.c. * lib/renameatu.h: Rename from lib/renameat2.h. * modules/renameat2: Rename from modules/renameatu. * modules/renameat2-tests: Rename from modules/renameat2-tests. All uses of "renameat2" in identifiers or file name changed to "renameatu", except for two instances in lib/renameatu.c that deal with the Linux kernel's renameat2 syscall.
* chdir-safer: remove this modulePaul Eggert2017-12-301-0/+3

* posixtm: remove PDS_LEADING_YEARPaul Eggert2017-11-241-0/+6
| | | | | | | | | | | | | | | | | This changes the API slightly, in a hopefully-innocuous way. Without this change the code had undefined behavior when a caller specified neither PDS_LEADING_YEAR nor PDS_TRAILING_YEAR. Problem reported by Pádraig Brady in: https://lists.gnu.org/r/bug-gnulib/2017-11/msg00048.html * NEWS: Mention this. * lib/posixtm.c (posix_time_parse): Treat the absence of PDS_TRAILING_YEAR as if PDS_LEADING_YEAR were present. * lib/posixtm.h (PDS_LEADING_YEAR): Remove (actually, leave it present, but define it as zero, for compatibility with existing source code). All other PDS_* values moved up. * tests/test-posixtm.c (LY): New macro. (T): Use it. Do not expect a particular numeric encoding for PDS_CENTURY etc.

(save_cwd): Use O_CLOEXEC instead of set_cloexec_flag. * m4/open-cloexec.m4: New file. * m4/open.m4 (gl_FUNC_OPEN): Require gl_PREPROC_O_CLOEXEC. Replace 'open' if O_CLOEXEC is not present. * m4/openat.m4 (gl_FUNC_OPENAT): Require gl_PREPROC_O_CLOEXEC. Replace 'openat' if O_CLOEXEC is not present. * modules/freopen (Depends-on): Depend on 'open' if replacing freopen. * modules/open (Files): Add m4/open-cloexec.m4. (Depends-on): Depend on cloexec if replacing 'open'. * modules/openat (Files): Add m4/open-cloexec.m4. (Depends-on): Depend on cloexec if replacing openat. * modules/popen-safer (Depends-on): Remove cloexec. * modules/save-cwd (Depends-on): Remove cloexec, and add fd-safer-flag and 'open'.

* xsetmode: new modulePaul Eggert2017-02-151-0/+4
| | | | | | | | | | | | | This is to fix a problem noted by Eric Blake. Code was using xfreopen to change files to binary mode, but this fails for stdout when in append mode. Such code should use xsetmode instead. * NEWS: Document incompatible changes to binary-io module. * lib/binary-io.c (__gl_setmode_check) [__DJGPP__ || __EMX__]: New function. * lib/binary-io.h (__gl_setmode): Rename from set_binary_mode.

* parse-datetime: handle timezones reentrantlyPaul Eggert2017-01-201-0/+4
| | | | | | | | | | | | | | | | | | This API change was prompted by a report by Pádraig Brady in: https://bug.debian.org/851934#10 To help fix the bug, make parse_datetime2 more reentrant. * NEWS: Document this incompatible change. * lib/parse-datetime.h, lib/parse-datetime.y (parse_datetime2): Add two arguments, the timezone and the timezone name. All callers changed. If TZ="..." is specified, use it for calculating defaults. * lib/parse-datetime.y: Don't include xalloc.h or use xmalloc, as this code should be usable in a library. (mktime_ok, get_effective_timezone): Accept timezone arg too. All callers changed. (get_tz): Remove. (get_effective_timezone): Check for failures. * modules/parse-datetime: Add time_r, time_rz. Remove xalloc.

* intprops, mktime, strtol: assume two's complementPaul Eggert2016-04-131-0/+4
| | | | | | | | | | | | | | | | | | These macros were not portable to every conforming C11 ones' complement platform. It's not worth the hassle of porting to some platforms that use ones' complement or signed magnitude, as such platforms are almost purely theoretical nowadays and porting even to some of them makes the code harder to review for little practical benefit. Problem reported by Florian Weimer in: https://sourceware.org/ml/libc-alpha/2016-04/msg00295.html * lib/intprops.h (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT) (TYPE_SIGNED_MAGNITUDE, _GL_INT_TWOS_COMPLEMENT): * lib/mktime.c (TYPE_TWOS_COMPLEMENT): * lib/strtol.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT) (TYPE_SIGNED_MAGNITUDE): Remove.

* intprops: revise _WRAPV macros, revert _OVERFLOWPaul Eggert2015-11-041-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The incompatible changes to the _OVERFLOW macros were too much of a hassle in practice, so revert them. Instead, change the new _WRAPV macros to make them closer in behavior to GCC 5's new builtin_add_overflow etc. functions. No other software was using these newly-added macros yet, so this should be OK. * NEWS: Revert previous change, since the incompatible change has been reverted, and nobody used the incompatible version. * doc/intprops.texi (Wraparound Arithmetic, Integer Type Overflow): Document revised behavior. (Integer Range Overflow): Adjust example to match above revisions. * lib/intprops.h (INT_ADD_OVERFLOW, INT_SUBTRACT_OVERFLOW) (INT_MULTIPLY_OVERFLOW): Revert previous change, so that these can be used in integer constant expressions again. (INT_CONST_ADD_OVERFLOW, INT_CONST_SUBTRACT_OVERFLOW) (INT_CONST_MULTIPLY_OVERFLOW): Remove, as these are no longer needed. (INT_CONST_ADD_WRAPV, INT_CONST_SUBTRACT_WRAPV) (INT_NEGATE_WRAPV, INT_CONST_MULTIPLY_WRAPV, INT_DIVIDE_WRAPV) (INT_REMAINDER_WRAPV, INT_LEFT_SHIFT_WRAPV): Remove, as they did not seem that useful. (INT_ADD_WRAPV, INT_SUBTRACT_WRAPV, INT_MULTIPLY_WRAPV) (_GL_INT_OP_WRAPV, _GL_INT_OP_WRAPV_LONGISH) (_GL_INT_OP_WRAPV_VIA_UNSIGNED): Support new semantics.

* intprops: add WRAPV and const flavors for GCC 5Paul Eggert2015-10-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If available, use GCC 5's builtin functions for efficient integer overflow checking. Also, add macros like INT_ADD_WRAPV that efficently and safely compute the low-order bits of the correct answer. A downside of these efficient functions is that they cannot be used in constant expressions, so add macros like INT_CONST_ADD_OVERFLOW and INT_CONST_ADD_WRAPV that can be used even in constant expressions. * NEWS: Document the incompatible changes to INT_ADD_OVERFLOW etc. * doc/intprops.texi (Integer Properties, Integer Type Overflow): Document the changes. (Wraparound Arithmetic): New section. (Integer Range Overflow): Put this subsection last, since it's least useful. * lib/intprops.h (INT_CONST_ADD_OVERFLOW) (INT_CONST_SUBTRACT_OVERFLOW, INT_CONST_MULTIPLY_OVERFLOW): New macros, with the meaning that INT_ADD_OVERFLOW etc. used to have.

* c-ctype: rewrite to use inline functionsPaul Eggert2015-09-251-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies maintenance, since it makes for just one implementation of each function, letting the compiler have the fun of optimization. In practice this works well nowadays with GCC. E.g., c_isascii might need only three instructions even though the source code lists every ASCII character individually in a large switch statement. Also, fix some z/OS porting bugs reported by Daniel Richard G. in: http://lists.gnu.org/archive/html/bug-gnulib/2015-09/msg00037.html * NEWS: Document the API change. * lib/c-ctype.c: Drastically simplify, since this now just expands inline functions. * lib/c-ctype.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In fact, access to the gnulib repository through CVS has been disabled, or more precisely, got broken and was never restored; see: <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00008.html> Note that support for CVS is not removed completely and unthinkingly by this change: only support for CVS checkouts of gnulib itself is removed. For example, the 'bootstrap' script still cater to .cvsingore files and CVS directories, for the benefit of those poor gnulib clients still stuck with CVS. Ditto for the 'gnulib-tool' script itself. * gnulib-tool: Simplify accordingly. * posix-modules: Likewise. * MODULES.html.sh: Likewise. * doc/gnulib.texi: No longer mention the decommissioned CVS gnulib repository. * doc/gnulib-intro.texi: Likewise. * doc/gnulib-readme.texi: Likewise. * doc/gnulib-tool.texi: In the examples and explanations, refer to a sample '.gitignore' file rather than a sample '.cvsignore'. * NEWS: Update. * m4/extensions.m4: While at it, remove a comment mistakenly referring to "CVS Autoconf" rather than "git Autoconf".

* config: drop scripts that automake says are not independentEric Blake2012-06-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | These three scripts are too closely tied to automake internals to be independently useful. In fact, automake would rather that people did not mix the latest version of these scripts with older versions of automake, as there is no effort being put into maintaining backwards-compatibility when these scripts are updated. The remaining scripts pulled from automake, such as mdate-sh or depcomp, are independently useful, so a future patch may end up reparenting those scripts to have gnulib instead of automake as the master owner. * config/srclist.txt: Drop elisp-comp, missing, and ylwrap. * build-aux/elisp-comp: Delete. * build-aux/missing: Likewise. * build-aux/ylwrap: Likewise. * modules/elisp-comp: Likewise. * MODULES.html.sh: Drop mention of elisp-comp. * NEWS: Mention this.
