2012-05-12ls: color each symlink-to-relative-name in / properlyJim Meyering
In order for ls --color to color each symlink, it must form the name of each referent and then stat it to see if the link is dangling, to a directory, to a file, etc. When the symlink is to a relative name, ls must concatenate the starting directory name and that relative name. When, in addition, the starting directory was "/" or "/some-name", the result was ill-formed, and the subsequent stat would usually fail, making the caller color it as a dangling symlink. * src/ls.c (make_link_name): Don't botch the case in which dir_name(NAME) == "/" and LINKNAME is relative. * tests/ls/root-rel-symlink-color: New file. Test for the above. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it. Reported by Mike Frysinger in http://bugs.gnu.org/11453 Bug introduced by commit v8.16-23-gbcb9078.
2012-05-02maint: adjust comments to avoid FP match on binary-operator-at-EOLJim Meyering
* src/ls.c (print_long_format): Reformat comment to avoid "==" at end of line. Also, "sortkey" is not a word: s/sortkey/sort key/. * src/ioblksize.h: Likewise, for "|" from a shell snippet. * src/runcon.c: Likewise, for "|" in grammar-like usage.
2012-04-19maint: ls: use stpncpy/stpcpy, not strncpy/strcpyJim Meyering
* src/ls.c (gobble_file): Move a decl "down". (make_link_name): Do not hard-code '/'. Use IS_ABSOLUTE_FILE_NAME and dir_len instead. Use stpcpy/stpncpy in place of strncpy/strcpy.
2012-04-19maint: modernize/clean-up a small function in ls.cJim Meyering
* src/ls.c (make_link_name): Adjust comment style to refer to VARIABLE names, not 'variable'. Move each of two declarations "down" to first use. Compare pointer to NULL, not to 0. Don't reuse local, "linkbuf" for a different purpose.
2012-02-20ls: adjust errnos indicating device non support for xattrsPádraig Brady
* src/ls.c (errno_unsupported): Remove EBUSY, as this caters for the case where ACLs can't be accessed because the _file_ is locked. http://lists.gnu.org/archive/html/bug-coreutils/2005-06/msg00191.html Also ENOENT is not safe to include as you get that if the _file_ is removed between the stat() and subsequent querying of xattrs.
2012-02-18ls: cache ACL- and CAP-querying syscall failuresJim Meyering
Like the optimization to avoid always-failing getfilecon calls, this change avoids always-failing queries for whether a file has a nontrivial ACL and for whether a file has certain "capabilities". When such a query fails for one file (indicating no support), we know it will always fail that way for the affected device. With this change, we have thus eliminated nearly all failing-unsupported getxattr syscalls. * src/ls.c (has_capability) [!HAVE_CAP]: Set errno to ENOTSUP. (errno_unsupported): Expand the list of E* errno values to match that of lib/acl-internal.h's ACL_NOT_WELL_SUPPORTED macro. (file_has_acl_cache, has_capability_cache): New functions. (gobble_file): Use them in place of non-caching ones. * NEWS (Improvements): Mention it. Suggested by Sven Breuner in http://thread.gmane.org/gmane.comp.gnu.coreutils.general/2187 While eliminating most getfilecon calls saved about 33%, eliminating these other calls can save almost all of the remaining ~67% cost, on some remote file systems.
2012-02-18ls: optimize for when getfilecon would often fail (~33% perf. gain)Jim Meyering
On systems or file systems without SELinux support, all getfilecon and lgetfilecon calls would fail due to lack of support. We can non- invasively cache such failure (on most recently accessed device) and avoid the vast majority of the failing underlying getxattr syscalls. * src/ls.c (errno_unsupported): New function. (selinux_challenged_device): New file-scoped global. (getfilecon_cache, lgetfilecon_cache): New error-caching wrapper functions. (gobble_file): Use the caching wrappers, for when many *getfilecon calls would fail with ENOTSUP or EOPNOTSUPP. Suggested by Sven Breuner in http://thread.gmane.org/gmane.comp.gnu.coreutils.general/2187 Improved-by: Pádraig Brady.

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>

2011-11-12ls: plug a per-argument leakJim Meyering
Using ls -l on an SELinux-enabled system would leak one SELinux context string per non-empty-directory command-line argument. * src/ls.c (free_ent): New function, factored out of... (clear_files): ...here. Use it. (extract_dirs_from_files): Call free_ent (f), rather than simply free (f->name). The latter failed to free the possibly-malloc'd linkname and scontext members, and thus could leak one of those strings per command-line argument. * THANKS.in: Update. * NEWS (Bug fixes): Mention it. Reported by Juraj Marko in http://bugzilla.redhat.com/751974.

2011-10-01ls: fix output of dangling symlinks colored as targetPádraig Brady
This is related to commit b7f2b51c, 2010-01-01, "ls: fix color of broken symlinks colored as target" which didn't handle the --dereference case. The simplest way to reproduce the resultant erroneous "argetm" is as follows: $ ln -s /no-such dangle $ env LS_COLORS=ln=target ls --dereference --color ls: cannot access dangle: No such file or directory argetmdangle This is also an issue with the `tree` utility, reported here: http://bugs.debian.org/586765 * src/ls.c (print_color_indicator): Move the handling of 'ln=target' in $LS_COLORS (color_symlink_as_referent == true) to a higher scope, to handle all cases where type == C_LINK. * tests/misc/ls-misc: Add a test case for the specific issue, and 2 further test cases to verify other code paths in this area. Reported by Jason Glassey.
2011-09-30ls: avoid reading beyond end of color indicatorJim Meyering
At first this looked like a buffer overrun, since there was no test to ensure that the buffer length was 6. However, since the LS_COLORS string is NUL-terminated and since settings within it are separated by ":" there was neither the risk of reading beyond end of buffer nor risk of a false-positive match. * src/ls.c (print_color_indicator): Use color_symlink_as_referent rather than manually comparing against "target" again. * src/system.h (STRNCMP_LIT): Correct description in comment.
2011-07-16ls: port to NonStop (Bug#9076)Paul Eggert

2011-05-13ls: allow stat-free use of --colorJim Meyering
Even on a system with d_type support, the default use of --color makes ls stat every file in order to be able to honor settings like EXEC, STICKY, ORPHAN, SETUID, etc., because those settings require information that is not provided by dirent.d_type. However, if for a potentially large performance gain, you are willing to disable those settings, you can now make ls --color give type-related coloring and perform no stat calls at all (other than the unavoidable call-per- command-line argument). Before this change, even with all of those attributes disabled, ls --color would still stat every directory. Now, we're down to the minimum of one stat call per command-line arg. * src/ls.c (gobble_file): With --color, don't stat a non-command-line-specified directory when no directory-coloring attribute is enabled. * tests/init.cfg (require_dirent_d_type_): New function. * tests/d_type-check: New script, mostly from Pádraig Brady. * tests/Makefile.am (EXTRA_DIST): Add it. * tests/ls/stat-free-color: New test. * tests/Makefile.am (TESTS): Add it. * doc/coreutils.texi (General output formatting): Describe how to use dircolors to make ls --color refrain from calling stat on a d_type-enabled file system. Prompted by a query from Josef Bacik.
2011-05-08maint: remove -Wmissing-field-initializers workaroundsPádraig Brady
* configure.ac: Rather than disabling -Wmissing-field-initializers, use the fact that gnulib now disables it automatically when required (on versions of GCC older than 4.7). * src/system.h: Remove the no longer needed DECLARE_ZEROED_AGGREGATE. * src/ls.c: Likewise. * src/pathchk.c: Likewise. * src/shred.c: Likewise. * src/stty.c: Likewise. * src/wc.c: Likewise.
