2012-02-12mv: "mv A B" would sometimes succeed, yet A would remain, ...Jim Meyering
But only when both A and B were hard links to the same symlink. * src/copy.c (same_file_ok): Handle another special case: the one in which we are moving a symlink onto a hard link to itself. In this case, we must explicitly tell the caller to unlink the source file. Otherwise, at least the linux-3.x kernel rename function would do nothing, as mandated by POSIX 2008. * tests/mv/symlink-onto-hardlink-to-self: New test. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it. Reported by Bernhard Voelker in http://bugs.gnu.org/10686
2012-02-06maint: add braces as requested by HACKING coding standardJérémy Compostella
* src/dd.c (dd_copy): Braces were missing for this do/while statement.
2012-01-31doc: clarify --help output for some optional argumentsPádraig Brady
* src/pr.c (usage): Fix the -S description to indicate that the argument is optional for the short option. * doc/coreutils.texi (pr invocation): Likewise. * src/od.c (usage): Fix the -S description to indicate that the argument is required for the short option. Clarify -w takes an argument and that it is optional.
2012-01-30maint: sort: remove the last uses of "'%s'" in diagnosticsJim Meyering
* src/sort.c (key_warnings): Use quote (quote_n, since there are two) rather than literal single quotes ('%s') in diagnostic.
2012-01-30mv: allow moving symlink onto same-inode dest with >= 2 hard linksJim Meyering
Normally, mv detects a few subtle cases in which proceeding with a same-file rename would, with very high probability, cause data loss. Here, we have found a corner case in which one of these same-inode tests makes mv refuse to perform a useful operation. Permit that corner case. * src/copy.c (same_file_ok): Detect/exempt this case. * tests/mv/symlink-onto-hardlink: New test. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it. Initially reported by: Matt McCutchen in http://bugs.gnu.org/6960. Raised again by Anders Kaseorg due to http://bugs.debian.org/654596. Improved-by: Paul Eggert.
2012-01-27maint: use single copyright year rangeJim Meyering
Run "make update-copyright".
2012-01-26maint: remove some redundant automake _SOURCESPádraig Brady
* src/Makefile.am: Remove auto generated entries.
2012-01-25realpath: avoid the use of printfPádraig Brady
This was seen to give an 11% performance improvement. * src/realpath.c (relpath): Avoid using printf. (process_path): Likewise.
2012-01-25realpath: remove extraneous '/' for --relative-to edge casesPádraig Brady
* src/realpath.c (path_common_prefix): Be consistent and always include a leading '/' in the count returned. (relpath): Account for the change in path_common_prefix() and avoid outputting extra '/' chars in relative paths that span the root dir. * tests/misc/realpath: Add the two reported cases. Reported by Mike Frysinger
2012-01-22maint: quote 'like this' or "like this", not `like this'Paul Eggert
* 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.
2012-01-20stat: clarify the description of the %o stat formatPádraig Brady
* src/stat.c (usage): Indicate this is a transfer size suggestion, rather than some persistent block size. * doc/coreutils.texi (stat invocation): Likewise.
2012-01-11maint: fix minor whitespace issuesPádraig Brady
The previous commit introduced a couple of spacing issues, luckily one of which caused a test to fail. * src/stat.c (default_format): Add a space so times are aligned. * src/tr.c (string2_extentd): Remove an extraneous space.
2012-01-11maint: adjust formatting of certain continued stringsJim Meyering
Add a rule to ding any source file that has a continued string with a word in the first column of the following line. Those tend to trigger malfunction in tools that try to map an arbitrary line number to an enclosing function name. Of course, very many strings do precisely this, *when they are part of the usage function*. So we exempt the body of each usage function. * src/dircolors.c (main): Separate a long, continued string into two separately-quoted parts. * src/od.c (decode_one_format): Likewise. (decode_one_format, main): Move a space from end of preceding line to the beginning of the continued line. * src/tr.c (unquote, string2_extend, validate): Likewise. * src/seq.c (main): Split in two and use string concatenation. * src/stat.c (default_format): Use a mix of techniques. * cfg.mk (sc_prohibit_continued_string_alpha_in_column_1): New rule. Exempt three files in src: system.h, od.c, printf.c.
2012-01-09maint: src/*.[ch]: convert more `...' to '...'Jim Meyering
Run this (twice): git grep -E -l '`.+'\' src/*.[ch] \ |xargs perl -pi -e 's/`(.+?'\'')/'\''$1/'
2012-01-09maint: src/*.c: change remaining quotes (without embedded spaces)Jim Meyering
Run this (twice): git grep -E -l '`[^ ]+'\' src/*.c \ |xargs perl -pi -e 's/`([^ ]+'\'')/'\''$1/'
2012-01-09maint: convert `...' to '...' in --help outputJim Meyering
All affected lines end with \ or \n\, so run this command until it produces no new changes (4 times): git grep -E -l '`[^ ]+'\''.*\\' src \ |xargs perl -pi -e 's/`([^ ]+'\''.*\\)/'\''$1/'
2012-01-09maint: adjust quoting: emit '...', not `...' in diagnosticsJim Meyering
* src/csplit.c (parse_repeat_count, extract_regexp): As above. * src/date.c (main): Likewise. * src/ls.c (decode_switches): Likewise. * src/od.c (decode_one_format, main): Likewise. * src/pathchk.c (no_leading_hyphen): Likewise. * src/pr.c (main, getoptarg): Likewise. * src/rm.c (diagnose_leading_hyphen): Likewise. * src/sort.c (key_warnings, incompatible_options, main): Likewise. * src/stat.c (print_esc_char): Print '\x', not `\x' in diagnostic. * src/test.c (main): Likewise. * src/touch.c (main): Likewise. * src/tr.c (build_spec_list, validate, append_range): Likewise. * tests/misc/mktemp: This is an unusual case, since the affected string contains only the ` of an `...' string. So we change the long ` to a lone '. * tests/pr/pr-tests: Manual quote adapting fix-up. * tests/ln/hard-to-sym: Likewise. * tests/split/suffix-length: Likewise. * tests/mv/part-fail: Likewise. * tests/misc/chcon: Likewise. * tests/misc/stat-printf: Likewise.
2012-01-09maint: prep for global quoting changes: handle irregular cases manuallyJim Meyering
* src/chroot.c (usage): Change ``...'' to '...', and describe the default more accurately (also adding quotes): s,/bin/sh,'/bin/sh -i', * src/join.c (usage): Change ` ...'' ' to "...''". * src/fmt.c (isopen): Change `' to '` in list of bytes, so that a subsequent change can safely perform the `...' to '...' conversion. * src/truncate.c (main): Tweak quoting in comments to use '...', not `...`, for consistency with the rest of comments in coreutils.
2012-01-07maint: update quoting of "Try `prog --help'" to "Try 'prog --help'"Jim Meyering
Automatically adjust both the source (now in only one place) and all tests that expect the resulting output via this: git grep -l 'Try.*--help' src/system.h tests \ | xargs perl -pi -e 's/Try \\?`(\S+ --help)/Try '\''$1/'
2012-01-07maint: use new emit_try_help in place of equivalent fprintfJim Meyering
Run this command: perl -0777 -pi -e \ 's/fprintf \(stderr, _\("Try `%s --help.*\n.*;/emit_try_help ();/m'\ src/*.c
2012-01-07maint: factor out all `Try --help'-emitting statementsJim Meyering
* src/system.h (emit_try_help): New function.
2012-01-05split: avoid failure due to leftover 'errno' valueBruno Haible
* src/split.c (lines_chunk_split): Fix logic bug that led to unwarranted failure of "split -n l/2 /dev/zero" on NetBSD 5.1. The same would happen when splitting a growing file, where open/lseek-end gives one size, but by the time we read, there is more data available. (bytes_chunk_extract): Likewise. * NEWS (Bug fixes): Mention this. * tests/split/l-chunk: The latter case was not exercised. Add code to do that. Bug introduced with the chunk-selecting feature in v8.7-25-gbe10739. Co-authored-by: Jim Meyering <meyering@redhat.com>
2012-01-03df: work around long-named /dev/disk/by-uuid/... symlinksJim Meyering
On systems with recent kernel/tools, a symlink from /etc/mtab to /proc/mounts, and a by-UUID mount (i.e., soon, nearly everyone), you will see something like the following when running "df -hT": (this has been truncated to fit in a width-limited ChangeLog file) Filesystem Type Siz... rootfs rootfs 11G udev devtmpfs 3.8G tmpfs tmpfs 774M /dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66 ext4 11G tmpfs tmpfs 1.6G /dev/sda2 ext3 494M /dev/sda5 ext4 12G /dev/sda6 ext4 9.9G Contrast that with what we're used to seeing (modulo the two entries mounted on "/", which is a separate problem): Filesystem Type Size Used Avail Use% Mounted on rootfs rootfs 11G 1.9G 8.0G 19% / udev devtmpfs 3.8G 0 3.8G 0% /dev tmpfs tmpfs 774M 376K 774M 1% /run /dev/sda3 ext4 11G 1.9G 8.0G 19% / tmpfs tmpfs 1.6G 8.0K 1.6G 1% /run/shm /dev/sda2 ext3 494M 78M 392M 17% /boot /dev/sda5 ext4 12G 7.6G 3.7G 68% /usr /dev/sda6 ext4 9.9G 6.6G 2.8G 71% /var When that long /dev/disk/by-uuid/... name is merely a symlink to a much shorter (and often more useful) device name like "/dev/sda3", and when it's part of a listing of all file systems, I would much prefer to see only the latter. Similarly, when using an encrypted root file system, you would see a name like /dev/mapper/luks-828fc648-9f30-43d8-a0b1-f7196a2edb66 pointing to say, /dev/dm-0, I prefer the shorter name. I.e., if I explicitly run "df -hT /dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66", then, it's fine -- and expected -- to print to the long name. It was explicitly given. However, with no non-option argument, df should print the shorter name. Note that performing this translation at a lower level (via a change to gnulib's mountlist.c) would make it impossible to distinguish those two cases. * src/df.c: Include "canonicalize.h". (get_dev): Add a parameter, telling when we're in process-all- mount-points mode; update all callers. When true, resolve UUID-suffixed symlinks. * NEWS (Changes in behavior): Mention it. Reported by Dan Jacobson in http://bugs.gnu.org/10363
2012-01-03realpath: a new program to print the resolved pathPádraig Brady
This program is compatible with other realpath(1) implementations, and also incorporates relpath like support, through the --relative options. The relpath support was suggested by Peng Yu, who also provided an initial implemenation of that functionality. * AUTHORS: Add my name. * NEWS: Mention the new command. * README: Likewise. * doc/coreutils.texi (realpath invocation): Add realpath info. * man/Makefile.am (realpath.1): Add dependency. * man/realpath.x: New template. * man/.gitignore: Ignore generated man page. * po/POTFILES.in: Add src/realpath.c. * src/.gitignore: Exclude realpath. * src/Makefile.am (EXTRA_PROGRAMS): Add realpath. * src/realpath.c: New file. * scripts/git-hooks/commit-msg: Add realpath to the list of prefixes. * tests/Makefile.am (TESTS): Add misc/realpath. * tests/misc/realpath: New file.
2012-01-02build: tail: avoid type/format mismatch warning from gccJim Meyering
Without this change, gcc's -Werror=format would complain that the '%lx' format requires 'long unsigned int', not 'int'. * src/tail.c (fremote): Use a temporary variable.
2012-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright".
2011-12-30build: avoid spurious test.c warning with -Wsuggest-attribute=pureJim Meyering
* src/test.c: Add pragma to suppress gcc-4.6.2's warning that "advance" might be candidate for attribute 'pure'.
2011-12-28tail: avoid theoretically undefined behaviorJim Meyering
* src/tail.c (start_lines): Do not form potentially-invalid address. Use safe_read's return value as a pointer offset only after ensuring that it is not SAFE_READ_ERROR (size_t)(-1). Spotted by coverity. Also, move declaration of "p" to be closer to first use.
2011-12-26doc: homologize ch{con,grp,mod,own} option descriptionsPádraig Brady
* src/chgrp.c (usage): Group associated options together, to aid users. Also minimize the differences between individual messages across these four commands, to aid translators. * src/chmod.c: Likewise. * src/chown.c: Likewise. * src/chcon.c (usage): Likewise. Document the --dereference option. Suggested by Paul Eggert and Jari Aalto
2011-12-26stat,tail: recognize new FS type: pipefsJim Meyering
* src/stat.c (human_fstype) [S_MAGIC_PIPEFS]: New case. * NEWS (Bug fixes): Mention this.
2011-12-24doc: stat: clarify that %t and %T expand to the file system typeJim Meyering
* src/stat.c (usage): Mention "file system type", not just "type" for %t and %T. Do not capitalize the first letter of each description.
2011-12-23tail: with -f, use polling when a file is on an FS of unknown typeJim Meyering
Before, we would use inotify in that case, which would work as long as updates were taking place locally, but not at all when remote. Move hard-coded list of known remote FS types into a more maintainable table in stat.c, alongside the list of FS names and magic numbers. Generate a new is_local_fs_type function. * src/Makefile.am (fs-is-local.h): New rule, generated file. * src/extract-magic: Revamp to parse local/remote keyword after each magic number in src/stat.c's case statements. Accept new --local option. * src/.gitignore: Ignore the generated fs-is-local.h. * src/tail.c [HAVE_INOTIFY]: Include fs-is-local.h. (fremote) [HAVE_INOTIFY]: Use the new function in place of the switch stmt with hard-coded list of FS types. Emit a warning when processing a file on a file system of unknown type. * NEWS (Changes in behavior): Mention it. Suggested by Sven Breuner.
2011-12-22tail,stat: add support for FhGFSJim Meyering
* src/stat.c (human_fstype): Add a case: fhgfs, 0x19830326. * src/tail.c (fremote): Add S_MAGIC_FHGFS. * NEWS (Bug fixes): Update the entry for GPFS to mention FhGFS, too. Reported by Sven Breuner.
2011-12-14du: -x should not count files in other file systemsPaul Eggert
This fixes Bug#10293, which I guess was introduced in commit 95c948b06a dated 2003-10-02. * NEWS: Document fix. * src/du.c (process_file): Don't count files in different file systems if -x is given. * tests/du/one-file-system: Test for this bug.
2011-12-12ls: give a more useful diagnostic for a bogus --time-style argJim Meyering
* src/ls.c (decode_switches): Replace our use of XARGMATCH with open-coded version so that we can give a better diagnostic. * tests/ls/time-style-diag: New file. * tests/Makefile.am (TESTS): Add it. Reported by Dan Jacobson in http://bugs.gnu.org/10253 with suggestions from Eric Blake and Paul Eggert.
2011-12-09maint: remove a misleading comment from shred.cJim Meyering
* src/shred.c: Remove obsolete TODO comment. The first two and the last item were done, adding --recursive (-r) is neither necessary nor appropriate, and I don't want to add --interactive. I don't see a need for the others. Prompted by comments from Amr Ali.
2011-12-08ls: be responsive to interrupts when color-listing large directoriesJim Meyering
Starting with commit adc30a83, when using --color, ls inhibited interrupts to avoid corrupting the state of an output terminal. However, for very large directories, that inhibition rendered ls uninterruptible for too long, including a potentially long period even before any output is generated. * src/ls.c: Two phases of processing are time-consuming enough that they can provoke this: the readdir loop and the printing loop. The printing was supposed to be covered by a call to process_signals in (print_name_with_quoting): ... but that call was mistakenly guarded by a condition that might be false for many or even all files being processed. Call process_signals unconditionally. (print_dir): Also call process_signals in the readdir loop. * NEWS (Bug fixes): Mention it. Reported by Arkadiusz Miśkiewicz in http://bugs.gnu.org/10243 Co-authored-by: Eric Blake <eblake@redhat.com>
2011-12-05ln: clarify usage of -L, -n, -TPaul Eggert
* src/ln.c (usage): Use clearer wording to describe the -L, -n, and -T options (Bug#9896).
2011-12-05maint: don't assume GNU make \# syntax (fix previous)Paul Eggert
* src/Makefile.am (fs_normalize_perl_subst, fs-magic, fs-kernel-magic): Undo previous patch; it missed a \#. (fs_normalize_perl_subst): Use \043 rather than \#. \043 is portable to all ASCIIish platforms, whereas \# is portable only to platforms that are compatible with GNU make (and are incompatible with POSIX make). Porting this to EBCDIC is left as an exercise for the reader....
2011-12-05maint: sort, stat: remove unused parametersJim Meyering
* src/sort.c (struct thread_args) [is_lo_child]: Remove member. (sortlines): Remove unused parameter, "is_lo_child". Update callers. * src/stat.c (out_epoch_sec): Mark unused parameter. (do_statfs, do_stat): Remove unused parameter, "terse". Update callers.
2011-12-05maint: don't assume GNU make \# syntaxPaul Eggert
* src/Makefile.am (fs_normalize_perl_subst): Don't make unportable assumption about \# in the right hand side of a macro definition. This works with GNU make, but not with POSIX make. Problem reported by Basavaraj B (Bug#10220). (fs-magic, fs-kernel-magic): Do the #-substitution here instead.
2011-12-04od,test: address warnings from gcc's -Wjump-misses-initJim Meyering
* src/test.c (unary_operator): gcc reported that initializations in two case statements were skipped. Enclose in braces. * src/od.c (decode_one_format): Likewise.
2011-12-04maint: remove redundant usage declarations (-Wredundant-decls)Jim Meyering
* src/csplit.c (usage): Remove declaration. * src/ls.c (usage): Likewise. * src/pr.c (usage): Likewise.
2011-11-20doc: clarify ln's --help outputJim Meyering
* src/ln.c (usage): Use TARGET, not "source" in description. Reported by Michael J Daniel in http://bugs.gnu.org/9896.
2011-11-20port to GNU hosts, where getuid and friends can failPaul Eggert
* src/groups.c (main): * src/install.c (need_copy): * src/su.c (log_su): * src/test.c (unary_operator): * src/whoami.c (main): Don't assume that getuid and friends always succeed. This fixes the same problem that we recently fixed with 'id'.
2011-11-20ln: fix position of --backup values descriptionErik Auerswald
* src/ln.c (usage): A paragraph describing interactions of -s with -L and -P somehow snuck in between the description of the --backup option and the values used to control it. Fix this by moving the value description up.
2011-11-16sort: clarify wording on -k syntaxEric Blake
* src/sort.c (usage): Use KEYDEF instead of POS, and call out the specific OPTS that can occur in KEYDEF. Based on a report by Lars Noodén, http://bugs.gnu.org/10019
2011-11-15id: fix bug when euid != ruidPaul Eggert
* src/id.c (main): Report an error if no args are given and getuid fails, because print_full_info needs ruid. Redo code so that getuid and friends are invoked only when needed; this makes the code easier to follow, and is how I found the above bug.
2011-11-15ls: another reword of generic size noteRuediger Meier
* src/system.h (emit_size_note): Use "unit" rather than "suffix", and move multiplication to example instead of in suffix list. See additional discussion in Bug#9939.
2011-11-15id: tweak commentEric Blake
* src/id.c (main): Replace confusing use of "etc.".
