* physmem: use sysinfo if _SC_PHYS_PAGES unavailableNatanael Copa2014-04-191-1/+20
| | | | | | | | | * lib/physmem.c (physmem_total): Some systems like musl libc do not (yet) support _SC_PHYS_PAGES. Use the linux syscall sysinfo as fallback if _SC_PHYS_PAGES or _SC_PAGESIZE fails. (physmem_available): Likewise for _SC_AVPHYS_PAGES. Signed-off-by: Natanael Copa <ncopa@alpinelinux.org>
* exclude: port to strict C99Paul Eggert2014-04-181-3/+3
| | | | | | | | Strict C does not allow converting a function pointer to void * and vice versa. Pass a pointer to a function pointer instead. * lib/exclude.c (add_exclude_file): Pass the address of the function pointer. (call_addfn): And deference the address here, to match.
* xalloc: allow x2nrealloc (P, PN, S) where P && !*PNPaul Eggert2014-04-121-7/+6
| | | | | | | * lib/xalloc.h (x2nrealloc): Extend slightly, to allow the current size to be zero even when the pointer is nonnull. This accommodates the use case where P is malloc (0) and *PN is 0 on a host where malloc (0) yields nonnull.
* fts: avoid unnecessary strlen callsEric Blake2014-04-091-0/+3
| | | | | | | | Not all platforms have _D_EXACT_NAMLEN. * lib/fts.c (_D_EXACT_NAMLEN): Restore definition when needed. Signed-off-by: Eric Blake <eblake@redhat.com>
* fts: avoid unnecessary strlen callsPaul Eggert2014-04-091-2/+3
| | | | | * lib/fts.c (fts_build): Go back to using _D_EXECT_NAMLEN when that can be faster than strlen.
* fts: avoid unnecessary strlen callsBernhard Voelker2014-04-091-8/+6
| | | | | | | | | * lib/fts.c (_D_EXACT_NAMLEN): Remove macro. (fts_build): Store the length of the dp->d_name entry in a local variable instead of calling strlen() several times via the above, removed macro. For 'rm -rf some-dir' with e.g. 1M directory entries, this speeds up the run by ~4%, and reduces the execution time by about a third if run via "ltrace -c rm -rf some-dir".
* obstack: Remove ancient NeXTSTEP gcc support conditionalPaul Eggert2014-03-271-4/+1
| | | | | | | | | | This change will ease merging with glibc. The "#if ... __NEXT__" causes a warning with -Wundef which glibc now enables by default. Problem reported by Will Newton in <http://lists.gnu.org/archive/html/bug-gnulib/2014-03/msg00032.html>. glibc <sys/cdefs.h> now uses __extension__ for GCC 2.8 or later, so go with that. * lib/obstack.h (__extension__):
* obstack: merge with glibc changesPaul Eggert2014-03-272-376/+383
| | | | | | * lib/obstack.c, lib/obstack.h: Merge from glibc. This is mostly indenting and commentary changes. Instances of 'register' have been removed.
* strftime: wrap macros in "do {...} while(0)"Bernhard Voelker2014-03-251-14/+34
| | | | | | | | | | * lib/strftime.c (DO_NUMBER): Wrap multi-statement code block of this macro in "do {...} while(0)" to prevent false use as a single statement, e.g., in an un-braced "{}" else-block. (DO_SIGNED_NUMBER, DO_TZ_OFFSET, DO_NUMBER_SPACEPAD): Likewise. (strftime_case_): Remove 'else' after 'goto' - which was the only non-fatal, un-braced use of one of the above macros. Spotted by coverity (NESTING_INDENT_MISMATCH).
* modechange: avoid memory leaks for invalid octal modesBernhard Voelker2014-03-251-2/+2
| | | | | | | | | | | | | | | * lib/modechange.c (mode_compile): During the parsing of notations like +40, free the 'mc' buffer for invalid mode strings like +17777 (greater than the maximum octal mode), =18 (bad octal mode characters) or u=1 ('affected' with octal modes). Reproducer, e.g.: $ valgrind --leak-check=full chmod +17777 file Introduced via the 2012-03-09 commit, 4730c3e3, "modechange: add notations +40, 00440, etc.". Spotted by coverity (RESOURCE_LEAK).
* regex: port to OS X 10.8.5 en_US.UTF-8 localePaul Eggert2014-03-061-10/+5
| | | | | | | | | | | | | This fixes a bug when ignoring case and when comparing the titlecase letter 'Lj' (U+01C8 LATIN CAPITAL LETTER L WITH SMALL LETTER J) to the corresponding uppercase letter 'LJ' (U+01C7 LATIN CAPITAL LETTER LJ). In the OS X 10.8.5 en_US.UTF-8 locale, the titlecase letter is neither lowercase nor uppercase, but uppercasing the titlecase letter (via towupper) yields the uppercase letter, so the two letters should match when ignoring case. Problem reported by Jim Meyering in <http://debbugs.gnu.org/16911#16>. * lib/regex_internal.c (build_wcs_upper_buffer, build_upper_buffer): Don't test whether a character is lowercase before uppercasing it.
* stdint, read-file: fix missing SIZE_MAX on Android (tiny change)Kevin Cernekee2014-03-052-2/+3
| | | | | | | | This is basically one of the options Bruno Haible proposed in: http://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00282.html * lib/sys_types.in.h (_GL_INCLUDING_UNISTD_H): New macro. * lib/stdint.in.h: Use it. * modules/stdint (Depends-on): Add sys_types.
* parse-datetime: fix crash or infloop in TZ="" parsingPádraig Brady2014-02-271-2/+5
| | | | | | | | | | | | | | | | This was reported in http://bugs.gnu.org/16872 from the coreutils command: date -d 'TZ="""' The infinite loop for this case was present since the initial TZ="" parsing support in commit de95bdc2 29-10-2004. This was changed to a crash or heap corruption depending on the platform with commit 2e3e4195 18-01-2010. * lib/parse-datetime.y (parse_datetime): Break out of the TZ="" parsing loop once the second significant " is found. Also skip over any subsequent whitespace to be consistent with the non TZ= case. * tests/test-parse-datetime.c: Add test cases for TZ="" parsing.
* savedir: new symbol for fast-read versionPaul Eggert2014-02-261-2/+5
| | | | | | | * lib/savedir.h (SAVEDIR_SORT_FASTREAD): New symbol, for programs like GNU cp that want to use SAVEDIR_SORT_INODE if available, SAVEDIR_SORT_NONE otherwise. Problem reported by Bernhard Voelker in: http://lists.gnu.org/archive/html/coreutils/2014-02/msg00037.html
* unistd: port readlink to Mac OS X 10.3.9Paul Eggert2014-02-251-0/+15
| | | | | | | * lib/unistd.in.h (_GL_INCLUDING_UNISTD_H): New macro, to work around self-include problem in Mac OS X 10.3.9 when combined with readlink module. Problem reported by Klaus Zietler in <http://bugs.gnu.org/16825>.
* diffseq: remove TOO_EXPENSIVE heuristicPaul Eggert2014-02-233-154/+21
| | | | | | | | | | | | | | | | | | | | | | Problem with diffutils reported by Vincent Lefevre in <http://bugs.gnu.org/16848>. The simplest solution is to remove the TOO_EXPENSIVE heuristic that I added to GNU diff in 1993. Although appropriate for circa-1993 hardware, these days the heuristic seems to be more trouble than it's worth. * lib/diffseq.h: Modernize citations. (struct context): Remove member too_expensive. All uses changed. (struct partition): Remove members lo_minimal, hi_minimal. All uses changed. (diag, compareseq): Remove arg find_minimal. All uses changed. (diag): Remove the TOO_EXPENSIVE heuristic that I added back in 1993 to make 'diff' run faster (but not as well) on large inputs. These days, computers are fast enough that it's typically better to run slower but more accurately. * lib/fstrcmp.c: Remove duplicate comment. * lib/fstrcmp.c (strcmp_bounded): * lib/git-merge-changelog.c (compute_differences): Adjust to diffseq.h changes.
* savedir: simplify by using stpcpyPaul Eggert2014-02-231-18/+16
| | | | | | * lib/savedir.c (direntry_t): Remove size member. All uses removed. (streamsavedir): Use stpcpy instead. * modules/savedir (Depends-on): Add stpcpy.
* exclude: add support for posix regexpsSergey Poznyakoff2014-02-212-33/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for POSIX extended regular expressions and fixes a long-standing memory leak (pattern buffer was never freed). It also implements a new interface function to read exclude patterns from a FILE, which passes an additional parameter to its callback function, thereby allowing to preserve its state between invocations. * lib/exclude.c (struct patopts): Pack regex and pattern into union. (pattern_buffer): New struct. (exclude): New member patbuf. (exclude_add_pattern_buffer): New function. (free_exclude_segment): Free regexps. (free_exclude): Free allocated pattern buffers. (exclude_patopts): New function. (file_pattern_matches): Use exclude_patopts. (add_exclude): support regexps. (add_exclude_fp): New function. (add_exclude_file): Rewrite using add_exclude_fp. (fnmatch_pattern_has_wildcards): Support posix extended regexps. * lib/exclude.h (EXCLUDE_REGEX, EXCLUDE_ALLOC): New flags. (add_exclude_fp) (exclude_add_pattern_buffer): New prototypes. * modules/exclude: Depends on regex and filename.
* savedir: add sorting arg to savedir, streamsavedir; remove fdsavedirSergey Poznyakoff2014-02-132-54/+125
| | | | | | | | | | | | | | | | | Patch based on an idea by Dick Streefland in <https://savannah.gnu.org/patch/?7892>. * NEWS: Document this. * lib/savedir.c (NAME_SIZE_DEFAULT): Remove. (direntry_t, comparison_function): New types. (direntry_cmp_name): New function. (direntry_cmp_inode) [D_INO_IN_DIRENT]: New function. (streamsavedir, savedir): New arg OPTION. (streamsavedir): Simplify memory allocation. (fdsavedir): Remove. * lib/savedir.h (enum savedir_option): New type. (streamsavedir, savedir): New arg OPTION. (fdsavedir): Remove.
* file-type: add support for doors and other less-common file typesPaul Eggert2014-02-051-11/+51
| | | | | | | Problem with S_ISDOOR reported by Rich Burridge. * lib/file-type.c (file_type): Do S_ISLNK early too. Do S_TYPEIS* macros before the rest. Add S_ISCTG, S_ISDOOR, S_ISMPB, S_ISMPC, S_ISMPX, S_ISNAM, S_ISNWK, S_ISOFD, S_ISOFL, S_ISPORT, S_ISWHT.
* pthread: work around winpthread header pollution on mingwEric Blake2014-01-232-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dan Berrange reported compilation failure of libvirt on Fedora 20 when cross-compiling to mingw; the problem was traced to bogus macros in the winpthreads <pthread.h> header shipped as part of mingw-headers 3.0. CC util/libvirt_util_la-virerror.lo In file included from /usr/i686-w64-mingw32/sys-root/mingw/include/sys/time.h:10:0, from ../gnulib/lib/sys/time.h:39, from ../gnulib/lib/sys/select.h:117, from util/virutil.h:31, from util/virerror.c:35: ../gnulib/lib/time.h:468:21: error: expected identifier or '(' before '{' token _GL_FUNCDECL_SYS (localtime_r, struct tm *, (time_t const *restrict __timer, ^ Gnulib's time.h was already working around the pthread.h pollution, but now that newer mingw has started providing struct timespec, the workaround was no longer being hit. Moving the pollution workaround to the wrapper around the broken header solves the problem. * lib/time.in.h: Move pthread workarounds... * lib/pthread.in.h: ...here. * m4/pthread.m4 (gl_PTHREAD_CHECK): Also build pthread.h when we detect macro pollution on mingw. * doc/posix-headers/pthread.texi (pthread.h): Document the problems.

* stdalign: port to HP-UX compilersPaul Eggert2014-01-201-1/+2
| | | | | * lib/stdalign.in.h (_Alignas): Use __attribute__ (__aligned__ (x)) if __HP_cc or __HP_aCC are nonzero.
* strtoimax: port to platforms lacking 'long long'Paul Eggert2014-01-161-6/+10
| | | | | | | | | | VMS's pre-C99 compiler lacks 'long long', so 'configure' doesn't check whether strtoll is declared, which causes the C file to wrongly report an error. Problem reported by Steven M. Schweda in: http://lists.gnu.org/archive/html/bug-diffutils/2014-01/msg00003.html * lib/strtoimax.c (strtoull): Declare only if HAVE_UNSIGNED_LONG_LONG_INT. (strtoll): Declare only if HAVE_LONG_LONG_INT.
* freadable, fwritable, fwriting: declare with the "pure" attributeJim Meyering2014-01-033-3/+3
| | | | | | | * lib/freadable.h (freadable): Declare with the "pure" attribute. * lib/fwritable.h (fwritable): Likewise. * lib/fwriting.h (fwriting): Likewise. Suggested by Bruno Haible.

* passfd: give nicer error for recvfd at eofEric Blake2013-12-241-3/+5
| | | | | | | | | | | | | 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. Signed-off-by: Eric Blake <eblake@redhat.com>
* gettimeofday: port recent C++ fix to EmacsPaul Eggert2013-12-171-20/+19
| | | | | | | | | | | | | | | | | | | 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. Eaton2013-12-171-0/+34
| | | | | | | | | | | | | | | 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.
* qacl: port to Windows betterPaul Eggert2013-12-171-5/+6
| | | | | | | | See Eli Zaretskii in <http://lists.gnu.org/archive/html/emacs-devel/2013-12/msg00593.html>. * lib/file-has-acl.c (acl_access_nontrivial): Return -1 and set errno if !HAVE_ACL_FIRST_ENTRY && !HAVE_ACL_TO_SHORT_TEXT && !HAVE_ACL_FREE_TEXT.

* base64: fix recent compilation regression on some compilersRV9712013-11-291-1/+4
| | | | | | | | | | This fixes a compile failure with "Sun C 5.8 Patch 121015-05 2007/08/01" which returns: "base64.c", line 99: void function cannot return value * lib/base64.c: Don't return the void function, instead split to a separate return statement.
* ignore-value: revert previous code changePaul Eggert2013-11-281-4/+6
| | | | | | | * lib/ignore-value.h (ignore_value): Use __extension__ and __typeof__ only for GCC 3.4 and later. Reported by Eric Blake in <http://lists.gnu.org/archive/html/bug-gnulib/2013-11/msg00102.html>. Change the comment to try to explain this better.
* selinux-h: improve stub types and add more stub functionsPádraig Brady2013-11-282-1/+12
| | | | | | | | | * 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 Eggert2013-11-271-4/+4
| | | | | | | | 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.
* quotearg: don't attempt to store 1 << 31 into an "int"Jim Meyering2013-11-221-1/+1
| | | | | | | | | | | * lib/quotearg.c (quotearg_buffer_restyled): Building coreutils with gcc's new -fsanitize=undefined and running its tests triggered some new test failures due to undefined behavior, all with this diagnostic: lib/quotearg.c:629:62: runtime error: left shift of 1 by 31 places \ cannot be represented in type int Rather than shifting "1" left to form a mask, shift the bits right and simply use "1" as the mask.

| | | | | | | | | | | | | | | | | | 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.

* obstack: pacify HP CPaul Eggert2013-10-311-13/+13
| | | | | | | | | * 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.
