| | | | | | * m4/threadlib.m4 (gl_AVOID_WINPTHREAD): New macro. (gl_THREADLIB_EARLY_BODY): Recognize when it was invoked, and set gl_use_threads accordingly.
* pthread_sigmask: Fix compilation error with --enable-threads=windows.Bruno Haible2019-05-182-71/+81
| | | | | | | | | | | | Reported by Tim Rühsen in <https://lists.gnu.org/archive/html/bug-gnulib/2018-01/msg00018.html> and Michele Locati in <https://lists.gnu.org/archive/html/bug-gettext/2019-04/msg00057.html>. * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Revert change from 2015-06-01. Test whether pthread_sigmask is a macro, regardless of $LIBMULTITHREAD. Consider it regardless whether module 'threadlib' is in use and regardless which threads API is chosen.
* close-stream, closein, closeout: simplifyPaul Eggert2019-05-147-40/+13
| | | | | | | | | | | | I noticed this opportunity for simplification while drafting a new, related module that I haven’t had time to finish yet. * m4/close-stream.m4, m4/closein.m4, m4/closeout.m4: Remove. * modules/close-stream (Files): Remove m4/close-stream.m4. (configure.ac): Omit gl_CLOSE_STREAM. * modules/closein (Files): Remove m4/closein.m4 (configure.ac): Omit gl_CLOSEIN. * modules/closeout (Files): Remove m4/closeout.m4.

* base64: Avoid false positive warning from Coverity.Bruno Haible2019-05-102-2/+11

* verify: remove verify_truePaul Eggert2019-05-094-11/+11

* Support C2X and C++17 static_assertPaul Eggert2019-05-095-58/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | C2X and C++17 finally added support for a simple, single-argument ‘static_assert’ that implements what the Gnulib ‘verify’ macro was doing back in 2005. Implement static_assert on older platforms. The only remaining advantage of ‘verify’ is a shorter name. * doc/posix-headers/assert.texi (assert.h): * doc/verify.texi (Compile-time Assertions): Modernize for C2X and C++17. * lib/verify.h (_GL_HAVE__STATIC_ASSERT1, _GL_HAVE_STATIC_ASSERT1): New macros. (_GL_HAVE__STATIC_ASSERT): Remove. (_GL_HAVE__STATIC_ASSERT): Rely more heavily on __STDC_VERSION__. (_GL_VERIFY_TRUE, _GL_VERIFY_TYPE): Remove 2nd arg, the diagnostic string. All callers changed. (_GL_VERIFY): Require 3 or more args, of which only the first 2 are used. All callers changed. (_Static_assert): Allow either 1 or 2 args, and define if !_GL_HAVE__STATIC_ASSERT1 instead of defining if !_GL_HAVE__STATIC_ASSERT. (static_assert): Define if !_GL_HAVE_STATIC_ASSERT1 instead of defining if !_GL_HAVE_STATIC_ASSERT. (verify_expr, verify): Don’t bother trying to copy the expression into the diagnostic, since 1-argument static_assert doesn’t. (verify): Prefer 1-argument _Static_assert if it works. * m4/assert_h.m4 (gl_ASSERT_H): Check for 1-argument static_assert.
* Fix _GL_HAVE__STATIC_ASSERT typoPaul Eggert2019-05-092-3/+9
| | | | | * lib/verify.h (_Static_assert): For the FreeBSD workaround, use _GL_HAVE__STATIC_ASSERT, not _GL_HAVE_STATIC_ASSERT.
* wcwidth: Ensure width 1, not 2, for ambiguous characters.Bruno Haible2019-05-054-2/+37
| | | | | | | | | | | Reported by Kiyoshi KANAZAWA <yoi_no_myoujou@yahoo.co.jp> via Akim Demaille <akim.demaille@gmail.com>. * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Check the width of U+2202. Use an en_US.UTF-8 locale, since that is more likely to be present than an fr_FR.UTF-8 locale. * tests/test-wcwidth.c (main): Check the width of U+2202. * doc/posix-functions/wcwidth.texi: Mention the issue.
* Port manywarnings to GCC 9Paul Eggert2019-05-033-11/+43

Adjust to minor wording changes in GCC 9’s --help=warnings output. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wabsolute-value, -Waddress-of-packed-member, -Wattribute-warning, -Wcannot-profile, -Wmissing-profile. Change -Wattribute-alias to -Wattribute-alias=2.

* mountlist: make parsing /proc/self/mountinfo more robustBernhard Voelker2019-04-102-33/+69
| | | | | | | | | | | | | | | | | | | | | | | | | Cater for the following issues with mountinfo parsing (the first one was reported by Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl> in <https://bugs.gnu.org/35137>). 1. The fields source, target, mntroot and fstype may contain characters like '\r'; sscanf(3) fails to read such values with the %s format specifier because it would stop at such characters. Example: "mount -t tmpfs tmpfs /foo^Mbar". The only true separator in that file is the ' ' character. 2. The source field may be an empty string, which happens e.g. with "mount -t tmpfs '' /target". 3. The fstype field may contain mangled characters as well which need unescaping. * lib/mountlist.c (terminate_at_blank): Add utility function. (read_file_system_list): In the block trying to read the mountinfo file, avoid using sscanf(3) with %s format; instead, parse the above fields separated by spaces one by one. This also handles the case when the source field is an empty string. Unescape the fstype field.
