* localeconv: Work around a mingw bug.Bruno Haible2023-04-281-1/+38
| | | | | | | | | | * m4/localeconv.m4 (gl_FUNC_LOCALECONV): Test whether fields of type 'char' are filled correctly. (gl_PREREQ_LOCALECONV): Test whether 'struct lconv' has the int_{p,n}_* members. * lib/localeconv.c (FIX_CHAR_VALUE): New macro. (localeconv): Replace negative field values with CHAR_MAX. * doc/posix-functions/localeconv.texi: Mention the mingw bug.
* stdlib: Fix error when cross-compiling.Bruno Haible2023-04-271-2/+2
| | | | | | | Reported by Pierre Labastie <pierre.labastie@neuf.fr> in <https://lists.gnu.org/archive/html/bug-gnulib/2023-04/msg00220.html>. * m4/stdlib_h.m4 (gl_STDLIB_H): Provide a 4th argument to AC_RUN_IFELSE.
* fdopendir: Fix fd leak and test failure on native Windows.Bruno Haible2023-04-276-44/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lib/dirent-private.h: On mingw, define 'struct gl_directory' as a wrapper around the original DIR. On MSVC, add an 'fd_to_close' field to 'struct gl_directory'. * lib/dirent.in.h (DIR): Define when DIR_HAS_FD_MEMBER is 0, i.e. on both mingw and MSVC. (GNULIB_defined_DIR): New macro. (opendir): Avoid incompatible redeclaration. (readdir): Consider REPLACE_READDIR. (rewinddir): Consider REPLACE_REWINDDIR. * m4/dirent_h.m4 (gl_DIRENT_DIR): New macro. (gl_DIRENT_H): Invoke it. (gl_DIRENT_H_DEFAULTS): Initialize REPLACE_READDIR, REPLACE_REWINDDIR. * modules/dirent (Makefile.am): Substitute DIR_HAS_FD_MEMBER, REPLACE_READDIR, REPLACE_REWINDDIR. -- * lib/dirfd.c (dirfd): If GNULIB_defined_DIR, just use the 'fd_to_close' field. * m4/dirfd.m4 (gl_FUNC_DIRFD): Set HAVE_DIRFD. Don't set REPLACE_DIRFD to 1 if HAVE_DIRFD is 0. If DIR_HAS_FD_MEMBER is 0, ensure dirfd.c gets compiled. * modules/dirfd (Files): Add lib/dirent-private.h. (Depends-on, configure.ac): Simplify conditions. -- * lib/closedir.c: Include <stdlib.h> always, for free(). (closedir): If GNULIB_defined_DIR, arrange to call close(dirfd(dirp)) at the end. On mingw, call free() of dirp. Prefer testing HAVE_DIRENT_H, for consistency with dirent.h. * m4/closedir.m4 (gl_FUNC_CLOSEDIR): Don't set REPLACE_CLOSEDIR to 1 if HAVE_CLOSEDIR is 0. If DIR_HAS_FD_MEMBER is 0, ensure closedir.c gets compiled. -- * lib/opendir.c: Include <stdlib.h> always. Include <string.h>. (opendir): On mingw, allocate the 'struct gl_directory' through malloc. If GNULIB_defined_DIR, set the 'fd_to_close' field to -1. Prefer testing HAVE_DIRENT_H, for consistency with dirent.h. * m4/opendir.m4 (gl_FUNC_OPENDIR): Don't set REPLACE_OPENDIR to 1 if HAVE_OPENDIR is 0. If DIR_HAS_FD_MEMBER is 0, ensure opendir.c gets compiled. -- * lib/fdopendir.c (fdopendir): If GNULIB_defined_DIR, use a simple implementation based on opendir and the fchdir module. If __KLIBC__, don't define unused auxiliary functions. * modules/fdopendir (Files): Add lib/dirent-private.h. -- * lib/readdir.c (readdir): On mingw, redirect to the original readdir function. Prefer testing HAVE_DIRENT_H, for consistency with dirent.h. * m4/readdir.m4 (gl_FUNC_READDIR): If DIR_HAS_FD_MEMBER is 0, ensure readdir.c gets compiled. * modules/readdir (configure.ac): Consider REPLACE_READDIR. -- * lib/rewinddir.c (rewinddir): On mingw, redirect to the original rewinddir function. Prefer testing HAVE_DIRENT_H, for consistency with dirent.h. * m4/rewinddir.m4 (gl_FUNC_REWINDDIR): If DIR_HAS_FD_MEMBER is 0, ensure rewinddir.c gets compiled. * modules/rewinddir (configure.ac): Consider REPLACE_REWINDDIR. -- * lib/fchdir.c (dir_info_t): Remove a FIXME.

* fclose: pacify gcc -Wanalyzer-file-leakPaul Eggert2023-04-241-0/+4
| | | | | | | | | | | | | | Without this patch, building coreutils with --enable-gcc-checking=expensive would fail with a message like “lib/exclude.c:682:6: error: leak of FILE 'in' [CWE-775] [-Werror=analyzer-file-leak]”, because Gnulib replaced fclose but not fopen, and GCC saw a call to fopen followed by a call to rpl_fclose. The patch causes GCC to instead see a call to rpl_fopen followed by rpl_fclose. * m4/fclose.m4 (gl_FUNC_FCLOSE): Replace fopen when replacing fclose. * modules/fclose (Depends-on): Add fopen. (configure.ac): Replace fopen when replacing fclose.
