coreutils/tests/split/line-bytes.sh, branch v8.26

maint: update all copyright year number ranges

2016-01-01T14:10:41Z

Run "make update-copyright" and then... * gnulib: Update to latest with copyright year adjusted. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * tests/sample-test: Adjust to use the single most recent year.

maint: use adaptive approach for `ulimit -v` based tests

2015-09-22T21:23:26Z

When configured with either 'symlinks' or 'shebangs' as value for the --enable-single-binary option, tests based on `ulimit -v` are skipped. The reason is that the multicall 'coreutils' binary requires much more memory due to shared libraries being loaded, and the size of the 'date' binary (~290KiB) compared to the multicall binary (~5MiB), of course. Finally, in the case of 'shebangs', the starting shell requires more memory, too Instead of using hard-coded values for the memory limit, use an adaptive approach: first determine the amount of memory for a similar, yet more trivial invocation of the command, and then do the real test run using that limit (plus some buffer in some cases). * init.cfg (require_ulimit_v_): Remove function. (get_min_ulimit_v_): Add function to determine the minimum memory limit required for a given command in an adaptive way. * cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name of the above function in the syntax-check rule. * tests/cp/link-heap.sh: Use the above function to determine the minimum memory required to run a command simpler than in the real test run. Use that limit plus a buffer there. While at it, change to list of commands in the subshell to fail also if the beginning `ulimit -v` fails. * tests/dd/no-allocate.sh: Likewise. * tests/misc/csplit-heap.sh: Likewise. * tests/misc/cut-huge-range.sh: Likewise. * tests/misc/head-c.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise - doing it separately for each program under test.

Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.

tests: avoid the :> construct which can hide errors

2014-03-05T19:02:20Z

On most shells `:>file || framework_failure_` will not evaluate the framework_failure_ even if there was an error writing the file. shells which do evaluate the failure are ksh 93u+ and bash 4.2, while shells wich don't include bash 4.3, solaris, freebsd, dash. Furthermore this construct is problematic on Solaris 10 sh, which will try to optimize away a `:' command in a loop after the first iteration, even if it is redirected. * tests/cp/link-deref.sh: Remove the leading colon on redirections. * tests/cp/reflink-perm.sh: Likewise. * tests/id/zero.sh: Likewise. * tests/install/install-C.sh: Likewise. * tests/misc/env.sh: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/runcon-no-reorder.sh: Likewise. * tests/mv/partition-perm.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/tail-2/inotify-rotate.sh: Likewise. * tests/tail-2/retry.sh: Likewise. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/touch/read-only.sh: Likewise. + cfg.mk (sc_prohibit_colon_redirection): A new syntax check to avoid further instances of this creeping in.

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.

tests: avoid spurious failure when SIZE_MAX is 2^32-1

2013-05-27T22:02:50Z

* tests/split/line-bytes.sh: Since we've limited virtual memory to 20MB, choose a smaller size, 1GiB (which is <= SIZE_MAX) rather than 1EiB, which is larger than SIZE_MAX on 32-bit systems. I confirmed that this test still fails when the split.c-modifying part of v8.21-58-gfec363c is backed out.

split: with --line-bytes only allocate memory as needed

2013-05-23T10:13:24Z

* src/split.c (line_bytes_split): Rewrite to only buffer when necessary. I.E. only increase the buffer when we've already lines output in a split and we encounter a line larger than the input buffer size, in which case a hold buffer will be increased in increments of the input buffer size. (lines_rr): Use the more abstract xalloc_die() just like we did in line_bytes_split(), rather than explicitly printing the "memory exhausted" message and exiting. * tests/split/line-bytes.sh: Add a new test for this function which previously had no test coverage. * tests/local.mk: Reference the new test. * NEWS: Mention the improvement.
