tests: fix 'make sc_tight_scope' on cygwin

2009-03-27T12:24:48Z

* src/Makefile.am (sc_tight_scope): Ignore leading underscores in symbols.

df: port the known-value fix to AIX as well

2009-03-26T07:53:21Z

* src/df.c (known_value): New function, which also works on AIX /proc file systems. (df_readable, show_dev): Use it instead of hardcoding comparison to UINTMAX_MAX. Suggested by Jim Meyering and Matthew Woehlke.

df: fix a bug when totaling unknown values

2009-03-26T07:53:21Z

* src/df.c (show_dev): Don't add UINTMAX_MAX to grand totals, as that value indicates that the true value is unknown; adding it effectively subtracts 1 from the total, whereas we want to leave the total alone.

pwd: support -L and -P

2009-03-25T12:33:32Z

* src/pwd.c (longopts): New variable. (logical_getcwd): New function. (main): Use it. (usage): Document new options. * doc/coreutils.texi (pwd invocation): Likewise. * NEWS: Likewise. * TODO (pwd): Mark it done. * tests/misc/pwd-option: New file. * tests/Makefile.am (TESTS): Add test. * THANKS: Update. Reported by Paul D. Smith, in savannah bug 24949.

ls: make it possible to disable coloring of hard links

2009-03-24T16:11:00Z

* src/ls.c (print_color_indicator): Don't color hard links if disabled (when there is an empty hl= in the LS_COLORS environment variable). * tests/ls/hardlink: Add test case for disabled hard link highlighting. * NEWS: Mention the change.

dd: use a more portable definition of O_FULLBLOCK

2009-03-20T14:16:50Z

* src/dd.c (O_FULLBLOCK): Compute its value without using a 180KB macro. This avoids triggering a compilation failure with HP-UX's cc. Reported by Matthew Woehlke.

sort: handle fd exhaustion better when merging

2009-03-18T20:44:37Z

This is an alternative to my 9 March patch labeled "Silently lower nmerge; don't (sometimes incorrectly) range-check" . It differs by not using 'dup' to probe for extra file descriptors; instead, it simply calls 'open' (and 'pipe') to open files and pipes, until one of these calls fails due to file descriptor exhaustion; it then backs off by 1, does a merge with the files that it has opened, and then retries with the (now-smaller) number of files. This patch requires quite a few more changes to the source code than the earlier patch, but it is in some sense "better" because it doesn't need to call "dup" ahead of time in order to decide whether "open" or "pipe" will fail. Also, it's more robust in the case where "open" or "pipe" fails with errno==EMFILE because some system-wide limit is exhausted. * src/sort.c (create_temp_file): New arg SURVIVE_FD_EXHAUSTION. (stream_open): New function, containing guts of xfopen. (xfopen): Use it. (pipe_fork): Set errno on failure. (maybe_create_temp): New function, containing guts of create_temp. (create_temp): Use it. (open_temp): Distinguish failures due to file descriptor exhaustion from other failures, and on fd exhaustion return a notice to caller rather than dying. Don't test execlp's return value; when it returns, it *always* returns -1. (open_input_files): New function. (mergefps): New arg FPS. It's now the caller's responsibility to open the input and output files. All callers changed. (mergefiles): New function. (avoid_trashing_input, merge): Handle the case where a single merge can't merge as much as we wanted due to file descriptor exhaustion, by merging as much as we can and then retrying. * tests/Makefile.am (TESTS): Add misc/sort-continue. * tests/misc/sort-continue: New file. * THANKS: Add Glen Lenker and Matt Pham who coauthored this patch.

system.h: correct compilation error: MAX not defined

2009-03-14T20:46:35Z

* src/system.h (io_blksize): Move definition down, so it follows that of MAX -- to avoid compilation failure on OpenSolaris. Reported by David Bartley. Details in http://lists.gnu.org/archive/html/bug-coreutils/2009-03/msg00190.html

cp: make -a option preserve xattrs, but with reduced diagnostics

2009-03-11T16:32:44Z

* copy.c (copy_attr_by_fd): Reduce xattr diagnostics for 'cp -a'. (copy_attr_by_name): Likewise. * cp.c (main): Preserve xattrs with -a option, when possible. * doc/coreutils.texi: Document that xattrs are preserved with cp -a, with no added diagnostics. * NEWS: Mention the change. * tests/misc/xattr: Add tests for 'cp --preserve=all' and 'cp -a'.

maint: remove an obsolete FIXME comment

2009-03-11T14:43:53Z

* src/Makefile.am (../AUTHORS): Remove obsolete FIXME comment. There are no longer any installed *.sh programs.
