Jim Meyering 2d437590 2009-10-15T21:04:51 don't let environment settings perturb build Setting the envvars, LIB_CLOCK_GETTIME, LIB_EACCESS or LIB_NANOSLEEP could cause a configure-time and/or build-time malfunction. Typically, a configure-time function-in-library test is performed via code like this: LIB_VAR= AC_SUBST([LIB_VAR]) prefix_saved_LIBS=$LIBS AC_SEARCH_LIBS([FUNC], [LIB_NAME], [test "$ac_cv_search_FUNC" = "none required" || LIB_VAR=$ac_cv_search_FUNC]) LIBS=$prefix_saved_LIBS However, in each of the files affected by this change, the LIB_VAR= initialization was omitted. Thus, when set in the environment, its value would propagate into generated Makefiles when FUNC is not found in LIB_NAME. * m4/clock_time.m4 (gl_CLOCK_TIME): Initialize AC_SUBST'd var. * m4/euidaccess.m4 (gl_PREREQ_EUIDACCESS): Likewise. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise.

Eric Blake 33790590 2009-10-01T11:57:47 rename: fix another cygwin 1.5 bug Cygwin 1.5 sometimes, but not always, failed on rename("dir1","dir2") when "dir2" exists. Beef up the m4 tests to more reliably detect at least one of cygwin's bugs, in spite of not knowing why the rename only failed sporadically (thankfully, cygwin 1.7 does not have the bug). Meanwhile, although NetBSD needs to share the hard link workarounds, it does not need the trailing dot and directory workarounds, so split the m4 test into two separate feature checks. * m4/rename.m4 (gl_FUNC_RENAME): Split cygwin bugs into two checks. * lib/rename.c (rpl_rename): Don't penalize NetBSD with unnecessary cygwin workarounds. Also work around bug with moving full directory onto an empty one. * modules/rename (Depends-on): Add canonicalize-lgpl, rmdir. Signed-off-by: Eric Blake <ebb9@byu.net>

Eric Blake 2f45acc3 2009-09-30T21:57:58 rename: fix Solaris 10 bug rename("file","name/") mistakenly succeeded. But since Solaris 10 already obeys POSIX behavior on rename("link/","name"), we avoid blindly forcing GNU behavior of rejecting symlinks with trailing slash. * m4/rename.m4 (gl_FUNC_RENAME): Detect Solaris bug. * lib/rename.c (rpl_rename): Don't cripple POSIX behavior if this was the only bug.

Eric Blake 6471b462 2009-09-24T10:57:14 getopt: fix inclusion guards for cygwin cygwin <unistd.h> includes <getopt.h>, but gnulib <getopt.h> includes <unistd.h>, so system declarations were happening after gnulib replacements, leading to multiply-defined rpl_readlink error on cygwin 1.5. The solution is to ensure that the system <unistd.h> is complete prior to any of gnulib's contents, by picking up system <getopt.h> in preference to a cycle to <unistd.h>. * modules/getopt-posix (Depends-on): Add include-next. (Makefile.am): Substitute more items in replacement header. * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Also check for native <getopt.h>. * lib/getopt.in.h (includes): Use split inclusion guard, and prefer <getopt.h> over include <unistd.h> when one is present.

Eric Blake 240faa59 2009-09-10T15:44:15 canonicalize-lgpl: use native realpath if it works Forward-looking to when more platforms comply with POSIX 2008, but don't provide glibc extensions. For example, this could fix // handling in cygwin 1.7 (well, if cygwin didn't have bugs in .. handling). canonicalize can't use native realpath, for the same reason that it does not use resolvepath. * lib/canonicalize-lgpl.c (realpath): Guard with FUNC_REALPATH_WORKS. * lib/stdlib.in.h (realpath): Make declaration optional based on HAVE_REALPATH. * m4/canonicalize-lgpl.m4 (gl_CANONICALIZE_LGPL): Check whether native realpath works. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Provide default. * modules/stdlib (Makefile.am): Substitute witness.

Eric Blake 99ad8ac7 2009-09-11T12:18:10 canonicalize, canonicalize-lgpl: use <stdlib.h> Match current gnulib conventions of glibc functions being declared in the same header as glibc. This makes it easier to replace broken canonicalize_file_name. canonicalize still requires "canonicalize.h" because canonicalize_filename_mode is not in glibc. With this patch, canonicalize-lgpl always provides realpath and canonicalize_file_name, while canonicalize can provide canonicalize_file_name but not realpath; if both modules are in use, canonicalize_file_name comes from the LGPLv2+ sources, but the testing comes from canonicalize. * modules/canonicalize-lgpl (Files): Drop canonicalize.h. (Include): Mention <stdlib.h>. (configure.ac): Mention functions we provide. * modules/canonicalize (configure.ac): Likewise. * m4/canonicalize-lgpl.m4 (gl_CANONICALIZE_LGPL): Always replace realpath if canonicalize_file_name is missing. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Provide defaults. * modules/stdlib (Makefile.am): Substitute witnesses. * lib/stdlib.in.h (canonicalize_file_name, realpath): Declare. * lib/canonicalize-lgpl.c (includes): Adjust accordingly. * lib/canonicalize.h (canonicalize_file_name): Drop declaration. * NEWS: Document this. * doc/glibc-functions/canonicalize_file_name.texi (canonicalize_file_name): Likewise. * doc/posix-functions/realpath.texi (realpath): Likewise. * tests/test-canonicalize-lgpl.c (includes): Use <stdlib.h>.

Eric Blake b472b51e 2009-09-11T14:57:01 canonicalize: avoid resolvepath Back when canonicalize merely provided canonicalize_file_name, resolvepath was more efficient than implementing a complete realpath.

Also, mingw failed to compile the module combination of canonicalize-lgpl and sys_stat, due to a link error on lstat. * modules/canonicalize (Depends-on): Add extensions, lstat, pathmax, stdlib.

Ralf Wildenhues 1bea6655 2009-09-02T20:07:33 Replace uses of obsolete autoconf macros in Jim's modules. The Autoconf macros AC_TRY_CPP, AC_TRY_COMPILE, AC_TRY_LINK and AC_TRY_RUN have been obsolete since Autoconf 2.55, and each use can evoke a warning from autoconf when run with -Wobsolete enabled. They were declared obsolete for good reasons (see the `AC_FOO_IFELSE vs AC_TRY_FOO' node in the Autoconf manual, recently renamed to `AC_ACT_IFELSE vs AC_TRY_ACT'), and we should not continue using the deprecated macros. * m4/d-type.m4 (gl_CHECK_TYPE_STRUCT_DIRENT_D_TYPE): Replace obsolete Autoconf macros with modern counterparts. * m4/dirfd.m4 (gl_FUNC_DIRFD): Likewise. * m4/dos.m4 (gl_AC_DOS): Likewise. * m4/fpending.m4 (gl_FUNC_FPENDING): Likewise. * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Likewise. * m4/getloadavg.m4 (gl_PREREQ_GETLOADAVG): Likewise. * m4/jm-winsz1.m4 (gl_WINSIZE_IN_PTEM): Likewise. * m4/link-follow.m4 (gl_AC_FUNC_LINK_FOLLOWS_SYMLINK): Likewise. * m4/ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): Likewise. * m4/mkdir-slash.m4 (gl_FUNC_MKDIR_TRAILING_SLASH): Likewise. * m4/mode_t.m4 (gl_PROMOTED_TYPE_MODE_T): Likewise. * m4/rename-dest-slash.m4 (gl_FUNC_RENAME_TRAILING_DEST_SLASH): Likewise. * m4/rename.m4 (gl_FUNC_RENAME): Likewise. * m4/rmdir-errno.m4 (gl_FUNC_RMDIR_NOTEMPTY): Likewise. * m4/rpmatch.m4 (gl_PREREQ_RPMATCH): Likewise. * m4/st_dm_mode.m4 (AC_STRUCT_ST_DM_MODE): Likewise. * m4/stat-time.m4 (gl_STAT_TIME): Likewise. * m4/utimes-null.m4 (gl_FUNC_UTIMES_NULL): Likewise.
