tests: avoid unusual (~1-in-20) failure of a new test

2009-04-24T19:34:59Z

* tests/misc/sort: Remove one of the generated tests. 363 remain in this file alone.

sort -m: don't segfault when output file is also an input file

2009-04-23T19:03:14Z

* src/sort.c (avoid_trashing_input): Fix an off-by-one error and guard the use of memmove. * NEWS (Bug fixes): Mention it. * tests/misc/sort: Add tests to exercise the offending code. * THANKS: Update. Reported by Otavio Salvador in http://bugs.debian.org/525048.

tests: misc/ls-misc: avoid shadowing local decl of $e

2009-04-09T13:29:59Z

* tests/misc/ls-misc (make_j_d): Rename latter $e to $env

id: fix infinite loop on some systems

2009-04-09T13:07:29Z

Steven Parkes reported that `id -G $USER` went into an infinite loop on Darwin systems for users in more than 10 groups: http://bugs.gentoo.org/show_bug.cgi?id=264007 * gl/lib/mgetgroups.c (mgetgroups): Work around buggy getgrouplist implementations that don't update the required size correctly, by doubling the result buffer and retrying. Also return the parameter updated by getgrouplist rather than its return value, as the documentation doesn't actually state the number of groups stored is returned by getgrouplist. * tests/misc/id-groups: Add test to exercise this logic * tests/Makefile.am: Reference new test * NEWS: Mention the fix * THANKS: Update

tests: don't use lang-default from individual tests

2009-03-29T17:54:54Z

* tests/sample-test: Don't recommend using lang-default here. It is now run for each test automatically, via TESTS_ENVIRONMENT. * tests/dd/reblock: Don't source lang-default here. * tests/misc/truncate-fail-diag: Likewise.

pwd: support -L and -P

2009-03-25T12:33:32Z

* src/pwd.c (longopts): New variable. (logical_getcwd): New function. (main): Use it. (usage): Document new options. * doc/coreutils.texi (pwd invocation): Likewise. * NEWS: Likewise. * TODO (pwd): Mark it done. * tests/misc/pwd-option: New file. * tests/Makefile.am (TESTS): Add test. * THANKS: Update. Reported by Paul D. Smith, in savannah bug 24949.

tests: ls -v: exercise yet another change in gnulib's new filevercmp

2009-03-24T21:33:47Z

* tests/misc/ls-misc: Add names with ~ and ~.1~ suffixes.

tests: adjust sort-continue not to fail under valgrind

2009-03-18T20:44:45Z

* tests/misc/sort-continue: Don't run cat inside fd-limited shell. If sort fails to run in an fd-limited shell, skip the test.

tests: add another sort/nmerge test

2009-03-18T20:44:45Z

* tests/Makefile.am (TESTS): Add sort-merge-fdlimit. * tests/misc/sort-merge-fdlimit: New file. * doc/coreutils.texi (sort invocation): Document that we now silently lower nmerge if necessary. Patch by Paul Eggert, Nima Nikzad, Max Chang, Alexander Nguyen, Sahil Amoli, and Nick Graham.

sort: handle fd exhaustion better when merging

2009-03-18T20:44:37Z

This is an alternative to my 9 March patch labeled "Silently lower nmerge; don't (sometimes incorrectly) range-check" . It differs by not using 'dup' to probe for extra file descriptors; instead, it simply calls 'open' (and 'pipe') to open files and pipes, until one of these calls fails due to file descriptor exhaustion; it then backs off by 1, does a merge with the files that it has opened, and then retries with the (now-smaller) number of files. This patch requires quite a few more changes to the source code than the earlier patch, but it is in some sense "better" because it doesn't need to call "dup" ahead of time in order to decide whether "open" or "pipe" will fail. Also, it's more robust in the case where "open" or "pipe" fails with errno==EMFILE because some system-wide limit is exhausted. * src/sort.c (create_temp_file): New arg SURVIVE_FD_EXHAUSTION. (stream_open): New function, containing guts of xfopen. (xfopen): Use it. (pipe_fork): Set errno on failure. (maybe_create_temp): New function, containing guts of create_temp. (create_temp): Use it. (open_temp): Distinguish failures due to file descriptor exhaustion from other failures, and on fd exhaustion return a notice to caller rather than dying. Don't test execlp's return value; when it returns, it *always* returns -1. (open_input_files): New function. (mergefps): New arg FPS. It's now the caller's responsibility to open the input and output files. All callers changed. (mergefiles): New function. (avoid_trashing_input, merge): Handle the case where a single merge can't merge as much as we wanted due to file descriptor exhaustion, by merging as much as we can and then retrying. * tests/Makefile.am (TESTS): Add misc/sort-continue. * tests/misc/sort-continue: New file. * THANKS: Add Glen Lenker and Matt Pham who coauthored this patch.
