* passfd: give nicer error for recvfd at eofEric Blake2013-12-243-3/+19
| | | | | | | | | | | | | I noticed that recvfd() fails with errno set to EACCES if the other end of the socket has closed (such as if it calls _exit()); but "Permission denied" as the strerror() message doesn't read very well. This improves things to give the nicer message: "Transport endpoint is not connected". * lib/passfd.c (recvfd): Fake ENOTCONN if other end closes early. * tests/test-passfd.c (main): Enhance test to cover this.

* gettimeofday: port recent C++ fix to EmacsPaul Eggert2013-12-175-35/+51
| | | | | | | | | | | | | | | | | | | Without this further patch, Emacs won't build due to the portcheck failing. Also, this simplifies the patch a bit. * lib/time.in.h (localtime, gmtime): Don't replace unless GNULIB_GETTIMEOFDAY. Treat them more like mktime. * lib/time.in.h (localtime, gmtime): * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): * modules/time (time.h): Don't worry about about the possibility of localtime and gmtime being absent; they're present in all C libraries we know about. * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): Don't assume sys_time is present and has been initialized. Instead, use a hack that should work even if it hasn't been. Don't use a portcheck for gmtime or localtime; this supports the hack. * modules/time (time.h): Substitute GNULIB_GETTIMEOFDAY.
* gettimeofday: fix C++ crosscompilationJohn W. Eaton2013-12-175-4/+69
| | | | | | | | | | | | | | | Never replace gmtime and localtime by macros when compiling with C++, this prevents <ctime> from being included. * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Do not define gmtime and localtime as preprocessor macros. Instead define some HAVE_GMTIME, HAVE_LOCALTIME, REPLACE_GMTIME, and REPLACE_LOCALTIME substitutions. * lib/time.in.h: Declare gmtime and localtime when needed. * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): AC_SUBST HAVE_GMTIME, HAVE_LOCALTIME, REPLACE_GMTIME, and REPLACE_LOCALTIME. * modules/time: Depend on gettimeofday, and substitute the above variables in time.h.

* md5, sha1, sha256, sha512: fix link error with partial libcryptoPádraig Brady2013-12-093-2/+12
| | | | | | | * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Only clear LIB_CRYPTO at init time, so that if early checks find crypto routines, while the last does not, then @LIB_CRYPTO@ is replaced correctly, avoiding link failures.
* md5, sha1, sha256, sha512: add gl_SET_CRYPTO_CHECK_DEFAULTPaul Eggert2013-12-072-3/+19
| | | | | | | | | | This provides a new way to specify the default for gl_CRYPTO_CHECK, one that is reflected in the --help message. Emacs uses this, as well as the old way. This attempts to implement a suggestion by Pádraig Brady in <http://lists.gnu.org/archive/html/coreutils/2013-12/msg00080.html>. * m4/gl-openssl.m4(gl_SET_CRYPTO_CHECK_DEFAULT): New macro. (gl_CRYPTO_CHECK): Use it. Mention the default in --help output.
* md5, sha1, sha256, sha512: add 'auto', and a way to specify defaultPaul Eggert2013-12-072-7/+19
| | | | | | | | * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Add support for a new option, --with-openssl=auto, which causes the library to be used if available and silently ignored if not. Add support to allow allow configure.ac to specify its own default, by setting with_openssl_default before invoking gl_INIT.

* bootstrap: warn about BSD toolchain snafuEric Blake2013-12-051-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | With my help on IRC, Roman Bogorodskiy identified a bug where the BSD autoconf wrapper script eats stdin[1], which in turn causes autopoint from gettext 0.18.3 to fail to find AM_GNU_GETTEXT_VERSION out of configure.ac[2], with this error: ./bootstrap: autopoint --force autopoint: *** Missing version: please specify in configure.ac through a line 'AM_GNU_GETTEXT_VERSION(x.yy.zz)' the gettext version the package is using [1] http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/184479 [2] http://git.sv.gnu.org/cgit/gettext.git/commit/gettext-tools/misc/autopoint.in?id=eea2dddde The workaround would be painful to automate (because gettext hardcodes the use of autom4te rather than honoring ${AUTOM4TE}, we'd have to create a temporary wrapper earlier in $PATH that forwards to the real autom4te-x.yz - basically, repeating the logic of what a wrapper script was supposed to do). Further, while the broken autom4te definitely hurts gettext 0.18.3, it tends to have no issues with gettext 0.18.2; and since the problem has been identified, it will not be long before fixed autom4te and/or improved gettext that is not so stubborn about using exactly 'autom4te' will be available. Therefore, for now we just warn about the situation. * build-aux/bootstrap: Alert users to a broken autom4te. Signed-off-by: Eric Blake <eblake@redhat.com>

* regex: suppress core dumps from detection codePádraig Brady2013-12-042-3/+19
| | | | | | | * m4/regex.m4 (gl_REGEX): Catch the SIGABRT and convert to SIGTERM to suppress core dumps that may well occur on glibc systems. These core dumps might not be cleaned up automatically, or could trigger some system core dump handling logic.
* md5, sha1, sha256, sha512: support mandating use of opensslPádraig Brady2013-12-042-3/+17
| | | | | | | | | | * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Adjust the --with-openssl description, to list the now 3 separate options. Also don't mention the default=no, since this is implicit given the option is described as --with-openssl rather than --without-openssl. If projects change the default they're free to document that. With --with-openssl[=yes] we now error out when the specified hash algorithm is not available in libcrypto.
* test-xvasprintf: disable some -Wformat-security diagnosticsIvailo2013-12-032-0/+13
| | | | | * tests/test-xvasprintf.c: Disable -Wformat-zero-length and -Wformat-nonliteral checks, as these edge cases are part of the test.
* regex: avoid glibc deadlock during configureEric Blake2013-12-032-2/+19
| | | | | | | | | | | | | | | | | | glibc has a known bug where certain corruptions of the heap can cause malloc to default to printing a debug message that includes a backtrace, but the act of getting the backtrace uses dlopen which in turn calls into malloc, causing a recursive lock ending in deadlock. Thus, when configure is probing for a known glibc heap corruption bug, the overall configure would hang. The solution suggested by glibc developers is to force malloc to quit printing debug messages, which avoids recursive malloc. * m4/regex.m4 (gl_REGEX): Avoid recursive malloc deadlock when glibc bug 15078 in turn triggers bug 16159.

| | | | | | | | | * lib/se-selinux.in.h: Change security_context_t to a typedef rather than a define, as it's a pointer type and so is better as a typedef to avoid issues declaring multiple variables with the comma operator. Also add stub for string_to_security_class(). * lib/se-context.in.h: Add stub functions for context_{type,range,role,user}_get().
* ignore-value: prefer GCC version back through 2.0Paul Eggert2013-11-272-4/+13
| | | | | | | | The code didn't match the comments, so I did a bit of software archaeology. GCC 2.0 seems to support __extension__ and __typeof__, so fix both code and comments to use 2.0. * lib/ignore-value.h (ignore_value): Use __extension__ and __typeof__ for GCC 2.0 through 3.3, too.

| | | | | | | | | | | | | | | | | | Avoid conditionals in the base64 encoding loop, which was seen to give a 60% throughput improvement with the base64 utility from coreutils: $ truncate -s100MiB file.in $ time base64-old -w0 < file.in >/dev/null real 0m0.302s $ time base64-new -w0 < file.in >/dev/null real 0m0.182s * lib/base64.c (base64_encode_fast): A new function to be called when we don't want to NUL terminate, and we have enough space in the output to encode the given input. (base64_encode): Call the _fast() version when appropriate. Also remove a redundant mask with 0x3F on the first encoded byte.

| | | | | | | | | * lib/obstack.h (obstack_free) [!__GNUC__]: Rewrite to avoid warning "conversion from pointer to smaller integer" from HP C-ANSI-C - cc version B9007AA/B3910B A.06.26. It's safe to assume C89 or later nowadays, so cast to void instead of int. Privately reported by H.Merijn Brand. Also, change header to match glibc's, to make checking against glibc easier.

* gnulib-tool: protect against CDPATHJim Meyering2013-10-282-0/+10
| | | | | | | | * gnulib-tool: Many "cd" built-in functions print a directory name to stdout when CDPATH is set, e.g., $ bash -c 'CDPATH=/; cd tmp' /tmp Unset it, when possible. Prompted by a comment from Bruce Korb.
* maint.mk: restore functionality removed by recent changev0.1Jim Meyering2013-10-282-1/+17
| | | | | | | | | | | | | | Sunday's change, v0.0-8062-g6b24f60, may have appeared correct from the context of a shallow-cloned gnulib repository: "git describe" would fail in such a directory. However, that change made it so the reported gnulib revision no longer includes the version number or a commit count, even when run from a full clone. * top/maint.mk (gnulib-version): Use the full "git describe" output when possible, e.g., the form above, rather than the abbreviated, no-tag, no-commit-count string, and fall back to using a 10-byte hash, rather than the default minimal-length hash prefix, since while the minimal-length one may be fine today, it is likely not to be unique for very long.
* Revert "error: make the module depend on vfprintf-posix"Eric Blake2013-10-282-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 88e5b4d4641f294d8f824d770c9c55a1abe49768. The GPL 'error' module is used by some of the gnulib testsuites; and for some projects that use LGPL 'vasnprintf' in their lib/ directory, having 'error' depend on GPL 'vfprintf-posix' meant that compilation breaks for those projects: autoreconf: running: aclocal -I m4 --force -I m4 missing file gnulib/tests/vasnprintf.c configure.ac:135: error: expected source file, required through AC_LIBSOURCES, not found m4/gnulib-comp.m4:518: gl_INIT is expanded from... configure.ac:135: the top level autom4te: /usr/bin/m4 failed with exit status: 1 I suspect that the problem encountered on OS/x was a warning from gcc complaining about inconsistent use of __attribute__((__format__ __printf__)) vs. ((__format__ __gnu_printf__)); so perhaps the real fix is to teach error.h to copy the extra care taken by stdio.h with regards to whether merely system or full GNU printf specifiers are being handled. But without actually reproducing that situation myself, the easiest action for now is to just revert the dependency that violates the 'Comment' section of vfprintf-posix.
* maint.mk: fix "release" target to build _versionJim Meyering2013-10-262-0/+12
| | | | | | | | | | This fixes a bug in README-release whereby following the outlined steps, one would publish a tarball whose programs would report --version output not consistent with the package version number. This bug caused grep-2.15 to produce a grep program whose --version option made it print 2.14.56-1e3d rather than 2.15. * top/maint.mk (release): Making this target build "_version" ensures that the new version number is reflected in configure.
