2014-10-17tests: avoid false failure when comparing /proc filesBernhard Voelker
At least the MHz number in /proc/cpuinfo may change, thus leading to a false positive failure when comparing the expected against the actual output file. Use an invariant file instead: /proc/version. * tests/misc/head-c.sh: s/cpuinfo/version/
2014-10-07wc: don't miscount /sys and similar file systemsPaul Eggert
Fix similar problems in head, od, split, tac, and tail. Reported by George Shuklin in: http://bugs.gnu.org/18621 * NEWS: Document this. * src/head.c (elseek): Move up. (elide_tail_bytes_pipe, elide_tail_lines_pipe): New arg CURRENT_POS. All uses changed. (elide_tail_bytes_file, elide_tail_lines_file): New arg ST and remove arg SIZE. All uses changed. * src/head.c (elide_tail_bytes_file): * src/od.c (skip): Avoid optimization for /sys files, where st_size is bogus and st_size == st_blksize. Don't report error at EOF when not optimizing. * src/head.c, src/od.c, src/tail.c: Include "stat-size.h". * src/split.c (input_file_size): New function. (bytes_split, lines_chunk_split, bytes_chunk_extract): New arg INITIAL_READ. All uses changed. Use it to double-check st_size. * src/tac.c (tac_seekable): New arg FILE_POS. All uses changed. (copy_to_temp): Return size of temp file. All uses changed. * src/tac.c (tac_seekable): * src/tail.c (tail_bytes): * src/wc.c (wc): Don't trust st_size; double-check by reading. * src/wc.c (wc): New arg CURRENT_POS. All uses changed. * tests/local.mk (all_tests): Add tests/misc/wc-proc.sh, tests/misc/od-j.sh, tests/tail-2/tail-c.sh. * tests/misc/head-c.sh: * tests/misc/tac-2-nonseekable.sh: * tests/split/b-chunk.sh: Add tests for problems with /proc and /sys files. * tests/misc/od-j.sh, tests/misc/wc-proc.sh, tests/tail-2/tail-c.sh: New files.
2014-03-31head: fix bug with head -c-N when stdin is not at startPaul Eggert
* src/head.c (elide_tail_bytes_file): Fix typo in lseek invocation. * tests/misc/head-c.sh: Add test for this bug. * NEWS: Document this.
2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-06-01tests: head-c: avoid spurious failure with a 32-bit size_tJim Meyering
* tests/misc/head-c.sh: Don't try to elide 1 exabytes, since on 32-bit systems, that number is not representable as a size_t. This command would fail on 32-bit systems, where SIZE_MAX < 1E: head --bytes=-E < /dev/null Instead of "E", use $SSIZE_MAX. For discussion, see http://bugs.gnu.org/13530
2013-04-25tests: fix usage of require_ulimit_Pádraig Brady
* init.cfg (require_ulimit_v_): Renamed from require_ulimit_ as this only checks for ulimit -v support. Other uses of ulimit -t and ulimit -n in tests shouldn't cause false failures if not supported. * cfg.mk (sc_prohibit_test_ulimit_without_require_): A new syntax check to ensure that require_ulimit_v_() is used iff required. * tests/misc/head-c.sh: Add missing call to require_ulimit_v_. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise. * tests/split/r-chunk.sh: Remove non mandatory require_ulimit_ call. * tests/misc/sort-merge-fdlimit.sh: Likewise. * tests/cp/link-heap.sh: Adjust to renamed require_ulimit_v_. * tests/dd/no-allocate.sh: Likewise. * tests/misc/csplit-heap.sh: Likewise. * tests/misc/cut-huge-to-eol-range.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise.
2013-04-14head: with --bytes=-N only allocate memory as neededPádraig Brady
* src/head.c (elide_tail_bytes_pipe): Don't use calloc as that bypasses memory overcommit due to the zeroing requirement. Also realloc rather than malloc the pointer array to avoid dependence on overcommit entirely. * tests/misc/head-c.sh: Add a test case. Fixes http://bugs.gnu.org/13530

2012-09-05build: don't use recursive make for tests/ subdirectoryStefano Lattarini
* Makefile.am (SUBDIRS): Remove 'tests'. (include): The '$(top_srcdir)/tests/local.mk' file. (check-root): Remove this convenience target, it's no longer needed now that the "real" check-root target once in 'tests/Makefile' will land in the top-level makefile. * configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'. * tests/Makefile.am: Rename ... * tests/local.mk: ... like this, with a lot of adjustments. * tests/init.cfg: Move ... * init.cfg: ... here. This is necessary, for a limitation of the gnulib-provided 'tests/init.sh', which unconditionally look for 'init.cfg' in the $(srcdir) directory. * tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests', not in '$srcdir', and extend $PATH with './src', not with '../src'. * tests/Coreutils.pm: Adjust similarly. * tests/pr/pr-tests.pl ($pfx): Likewise.
2012-08-30tests: add .sh and .pl suffixes to shell and perl tests, respectivelyStefano Lattarini
Not only this shrinks the size of the generated Makefile (from > 6300 lines to ~3000), but will allow further simplifications in future changes. * tests/Makefile.am (TEST_EXTENSIONS): Add '.sh' and '.pl'. (PL_LOG_COMPILER, SH_LOG_COMPILER): New, still defined simply to $(LOG_COMPILER) for the time being. (TESTS, root_tests): Adjust as described. * All tests: Rename as described.
