tests: convert nearly all `...` expressions to $(...)

2012-04-04T10:20:56Z

Exempt init.sh because it runs before we're assured to have a shell that groks $(...). Exempt *.mk because "$" would have to be doubled, and besides, any `...` expression in a .mk file is almost certainly evaluated before init.sh is run. Finally, also exempt the perl-based tests, because perl's `...` cannot be converted to $(...). Do that by running this command: git grep -l '`.*`' tests \ | grep -Ev 'init\.sh|\.mk$' | xargs grep -Lw perl \ | xargs perl -pi -e 's/`(.*?)`/\$($1)/g' One minor fix-up change was required after that, due to how quoting differs: diff --git a/tests/chmod/equals b/tests/chmod/equals - expected_perms=$(eval 'echo \$expected_'$dest) + expected_perms=$(eval 'echo $expected_'$dest) Another was to make these required quoting adjustments: diff --git a/tests/misc/stty b/tests/misc/stty ... - rev=$(eval echo "\\\$REV_$opt") + rev=$(eval echo "\$REV_$opt") ... - rev1=$(eval echo "\\\$REV_$opt1") - rev2=$(eval echo "\\\$REV_$opt2") + rev1=$(eval echo "\$REV_$opt1") + rev2=$(eval echo "\$REV_$opt2") Also, transform two files that were needlessly excluded above: (both use perl, but are mostly bourne shell) perl -pi -e 's/`(.*?)`/\$($1)/g' \ tests/du/long-from-unreadable tests/init.cfg

tests: skip part of dd/sparse on some file systems

2012-03-23T11:47:52Z

* tests/dd/sparse: The last two parts of this test would fail due to the underlying file system at least on Solaris 10 with NFS. That file system would report that a 3MiB file was occupying <= 1KiB of space for nearly 50 seconds after creation. Improved-by: Bernhard Voelker

tests: avoid spurious dd/sparse failure

2012-03-20T10:30:39Z

* tests/dd/sparse: Allow for greater variation in sparse-block counts. Reported by Nelson H. F. Beebe and Bruno Haible.

tests: work around a block alignment issue in dd/sparse

2012-03-02T10:57:56Z

Prompted by the continuous integration build failure at: http://hydra.nixos.org/build/2188210 (which uses XFS). * tests/dd/sparse (alloc_equal): Add a block allocation comparison function that accounts for variations due to alignment.

dd: add support for the conv=sparse option

2012-02-29T00:17:56Z

Notes: Small seeks are not coalesced to larger ones, like is done in cache_round() for example. conv= is used rather then oflag= for FreeBSD compatibility. * src/dd.c (final_op_was_seek): A new global boolean to flag whether the final "write" was converted to a seek. (usage): Describe the new conf=sparse option. (iwrite): Convert a write of a NUL block to a seek if requested. (do_copy): Initialize the output buffer to have a sentinel, to allow for efficient testing for NUL output blocks. If the last block in the file was converted to a seek, then convert back to a write so the size is updated. * NEWS: Mention the new feature. * tests/dd/sparse: A new test for the feature. * tests/Makefile.am: Reference the new test.

dd: fix issues in the count_bytes and seek_bytes flags change

2012-02-13T21:58:21Z

These edge cases were missed in the previous commit 140eca15c. * src/dd.c (main): Include the bytes slop when truncating without further I/O. Don't invalidate the whole file cache in the case where 0 < count < ibs. * tests/dd/bytes: Change to using the independent truncate command to generate the file for comparison. Remove a redundant test case and replace with one testing the truncation only logic.

dd: add count_bytes, skip_bytes and seek_bytes flags

2012-02-12T17:34:28Z

dd now accepts the count_bytes and skip_bytes input flag and the seek_bytes output flag, to more easily allow processing portions of a file. * src/dd.c (scanargs): Compute skip_records and skip_bytes when 'skip_bytes' iflag is used. Compute max_records and max_bytes when 'count_bytes' iflag is used. Compute seek_records and seek_bytes when 'seek_bytes' oflag is used. (skip_via_lseek): Use new 'bytes' parameter and handle potential 'records' equals to zero. Update the bytes parameter when called with 'fdesc' equal to STDOUT_FILENO. Update the header comments. (dd_copy): Skip accordingly to skip_records AND skip_bytes. Count accordingly to max_records AND max_bytes. Seek on output accordingly to seek_records AND seek_bytes. * NEWS (New features): Mention it. * doc/coreutils.texi (dd invocation): Detail new flags and behaviors. * tests/dd/bytes: New file. Tests for these new flags. * tests/Makefile.am (TESTS): Add it.

maint: use single copyright year range

2012-01-27T10:35:24Z

Run "make update-copyright".

maint: quote 'like this' or "like this", not `like this'

2012-01-22T23:26:38Z

* doc/coreutils.texi (Formatting the file names): coreutils now quotes 'like this'. * man/help2man: * src/timeout.c (usage): Quote 'like this' in diagnostics. * HACKING, Makefile.am, NEWS, README, README-hacking, TODO, cfg.mk: * doc/Makefile.am, doc/coreutils.texi, m4/jm-macros.m4: * man/Makefile.am, man/help2man, src/Makefile.am, src/copy.h: * src/extract-magic, src/ls.c, src/pinky.c, src/pr.c, src/sort.c: * src/split.c, src/timeout.c, src/who.c, tests/dd/skip-seek-past-file: * tests/pr/pr-tests: Quote 'like this' in commentary. * cfg.mk (old_NEWS_hash): Update due to changed old NEWS.

tests: change `...' to '...' on lines not matching /[=\$]/

2012-01-09T20:50:08Z

Exempt lines with '$' or '=', since those are prone to improper conversion. Run this: git grep -l "\`[^']*'" tests \ |xargs perl -pi -e '/[=\$]/ and next;s/\`([^'\''"]*?'\'')/'\''$1/g'
