coreutils/tests, branch v8.8

maint: correct test-related comments

2010-12-22T10:52:11Z

* tests/mv/i-3: Adjust comment to match just-changed code. Spotted by Pádraig Brady. * tests/init.cfg (retry_delay_): Correct spelling of function name in usage example.

tests: mv/i-3: avoid false-positive failure on a slow/busy system

2010-12-22T09:29:30Z

* tests/mv/i-3: Quadruple the timeout duration. Without this, I saw an expired timeout on a heavily-loaded system.

tests: avoid new false-positive failure on at least FreeBSD 8.1

2010-12-21T08:30:55Z

* tests/mv/trailing-slash: Accommodate different diagnostic on FreeBSD 8.1.

tests: sync init.sh from gnulib

2010-12-19T04:03:21Z

* tests/init.sh (setup_): Initialize fail=0 before invoking mktempd_. Ensure that IFS is defined initially. (mktempd_): Remove fail=0 initialization; no longer needed.

cp: ensure backups are created when -T specified

2010-12-19T00:36:29Z

* src/cp.c (do_copy): When -T is specified, initialize the NEW_DST and SB variables, which are checked when running: cp -T --force --backup file file * tests/cp/backup-1: Add the -T case

sort: use at most 8 threads by default

2010-12-19T00:33:45Z

* src/sort.c (main): If --parallel isn't specified, restrict the number of threads to 8 by default. If the --parallel option is specified, then allow any number of threads to be set, independent of the number of processors on the system. * doc/coreutils.texi (sort invocation): Document the changes to determining the number of threads to use. Mention the memory overhead when using multiple threads. * tests/misc/sort-spinlock-abuse: Allow single core systems that support pthreads. * tests/misc/sort-stale-thread-mem: Likewise. * tests/misc/sort-unique-segv: Likewise. * NEWS: Mention the change in behaviour.

tests: avoid spurious du/bigtime failure

2010-12-18T07:04:46Z

* tests/du/bigtime: Map nonzero block count to 0. Reported by Assaf Gordon. * THANKS: Update.

tests: set fail=0 by default

2010-12-18T06:40:20Z

* tests/init.sh (setup_): Set fail=0. This was the intent as per but the assignment in mktempd_ is ineffective, since mktempd_ is used inside `` and its assignments are in a subshell.

sort: fix hang with sort --compress

2010-12-16T21:55:31Z

* NEWS: Document this. * src/sort.c (UNCOMPRESSED, UNREAPED, REAPED): New constants. (struct tempnode): New member 'state', to hold these constants. The pid member is now undefined if state == UNCOMPRESSED. (struct sortfile): Replace member 'pid' with member 'temp'. (uintptr): Remove. (proctab_hasher, proctab_comparator, register_proc, delete_proc): Proctab entries are now struct tempnode *, not pid_t, to handle the case where multiple tempnode objects correspond to the same pid. This avoids a race condition that can cause a hang. (register_proc): Arg is now struct tempnode *, not pid_t. All callers changed. (delete_proc): Set tempnode state to REAPED. (create_temp_file): No need to set pid member here; it's now done when the pid is known. (maybe_create_temp, create_temp): Remove PPID arg. Return struct tempnode *, not char *. All callers changed. (maybe_create_temp): Set node state to UNCOMPRESSED or UNREAPED. No need to set node->pid to 0. (open_temp): Replace NAME and PID args with a single TEMP arg. All callers changed. Wait only for unreaped children. (zaptemp): Wait for decompressor to finish before removing its temporary-file input. This avoids .nfsXXXX hassles with NFS and fixes a race (leading to a hang) regardless of NFS. (open_input_files): Adjust to new way of dealing with temp files and their subprocesses. * tests/Makefile.am (TESTS): Add misc/sort-compress-hang. * tests/misc/sort-compress-hang: New file.

sort: don't dump core when merging from input twice

2010-12-16T08:04:32Z

* NEWS: Document this. * src/sort.c (avoid_trashing_input): The previous fix to this function didn't fix all the problems with this code. Replace it with something simpler: just copy the input file. This doesn't change the number of files, so return void instead of the updated file count. Caller changed. * tests/misc/sort-merge-fdlimit: Test for the bug.
