2009-10-23build: prohibit improper use of stat and lstatEric Blake
* cfg.mk (sc_prohibit_stat_macro_address): New rule. * src/ln.c (do_link): Adjust comment to avoid false positive. * src/stat.c (do_stat): Likewise. * src/touch.c (main): Likewise.
2009-09-25ln: add -L/-P optionsEric Blake
* src/ln.c (STAT_LIKE_LINK): Delete. (logical): New flag. (long_options): Add -L, -P. (usage): Mention them. (main): Choose between them. (do_link): Perform correct action. * tests/ln/misc: Move hard-to-sym portion of test... * tests/ln/hard-to-sym: ...into new test, and add more. * tests/Makefile.am (TESTS): Run new test. * NEWS: Document this. * doc/coreutils.texi (link invocation, ln invocation): Likewise. * bootstrap.conf (gnulib_modules): Add linkat.
2009-09-21doc: mention the texinfo documentation in --helpPádraig Brady
* src/system.h: Rename emit_bug_reporting_address() to emit_ancillary_info() and update it to not print the translation project address in en_* locales, and _do_ print it in the 'C' (and other) locales so that it's included in the default man page. Also mention how to invoke the texinfo documentation for each command. Also move the "hard-locale.h" include to the 8 files that now use it. * man/help2man: Strip the newly added texinfo reference from the --help output as a more verbose version is already added by help2man. Suggestion from C de-Avillez

2008-06-16remove redundant const directivesJim Meyering
In 1463824d8e7f72c31f1d803d7cfe2b608ccafc5c, I added some missing "const" directives, as well as some new, redundant ones. This removes the redundant ones. Pointed out by Eric Blake. * base64.c, cat.c, chcon.c, chgrp.c, chmod.c, chown.c, comm.c: * cp.c, csplit.c, cut.c, date.c, dd.c, df.c, dircolors.c, du.c: * env.c, expand.c, fmt.c, fold.c, groups.c, head.c, id.c: * install.c, join.c, kill.c, ln.c, ls.c, md5sum.c, mkdir.c: * mkfifo.c, mknod.c, mktemp.c, mv.c, nice.c, nl.c, od.c: * paste.c, pathchk.c, pinky.c, pr.c, ptx.c, readlink.c, rm.c: * rmdir.c, runcon.c, seq.c, shred.c, shuf.c, sort.c, split.c: * stat.c, stty.c, su.c, sum.c, tac.c, tail.c, tee.c, timeout.c: * touch.c, tr.c, truncate.c, tty.c, uname.c, unexpand.c, uniq.c: * wc.c, who.c: Remove redundant const directives. * maint.mk (sc_const_long_option): Don't require redundant "const".

2006-11-18"ln --backup f f" produces a misleading diagnostic:Jim Meyering
ln: creating hard link `f' => `f': No such file or directory * src/ln.c (do_link): Give a better diagnostic in this unusual case. (do_link): Rename local: s/lstat_ok/dest_lstat_ok/. * tests/ln/Makefile.am (TESTS): Add hard-backup. * tests/ln/hard-backup: New test for the above.
2006-09-19* src/ln.c (target_directory_operand): Rewrite to avoid portingPaul Eggert
problem on Tandem reported by Matthew Woehlke in <https://savannah.gnu.org/bugs/?17172>.
2006-09-03Don't include dirname.h, since system.h does it now.Paul Eggert
2006-08-28* src/copy.c (copy_internal): Don't test whether macros likePaul Eggert
S_ISLNK are defined, since they're always defined now. * src/cp.c (main): Likewise. * src/ln.c (main): Likewise. * src/ls.c (get_link_name, make_link_name): Likewise. * src/mkfifo.c (usage): Likewise. * src/who.c (S_IWGRP): Likewise.
2006-07-01* src/ln.c (do_link): Use new, shorter URL, for ag-review link.Jim Meyering
2006-04-12(linkfunc): Remove. This method ran into a compiler/linkerPaul Eggert
bug in Interix. Just call symlink or link directly. All uses changed.
2006-03-26(target_directory_operand, main): Use new last_component, in place of base_name.Jim Meyering
2005-11-16(do_link, usage): Improve quality of ln's diagnostics.Paul Eggert
(do_link): Don't use alloca on a buffer of unbounded size.
2005-11-05Include filenamecat.c.Jim Meyering
(FILE_BASENAME_CONCAT): Remove. (do_link): Remove last arg DEST_IS_DIR. All callers changed. (main): Use file_name_concat, base_name, and strip_trailing_slashes instead of FILE_BASENAME_CONCAT. This simplifies the code, and avoids the use of alloca.
2005-10-28(FILE_BASENAME_CONCAT): Omit unnecessary slashes in thePaul Eggert
boundary between DEST and SOURCE in the result.
2005-08-22(do_link): If ln is invoked with --interactive (-i),Jim Meyering
encounters an existing destination file, and gets an affirmative response, then first try to unlink the destination file rather than simply failing. Suggestion from Karl Berry.
2005-08-21(main): Declare `target_directory' with const attribute.Jim Meyering
2005-06-16Finally remove support for --version-control=S (-V).Jim Meyering
It was deprecated nearly 6 years ago and has been warning users to switch to --backup=S since fileutils-4.0j.
2005-06-02(FILE_BASENAME_CONCAT): Renamed from PATH_BASENAME_CONCAT.Paul Eggert
All uses changed.
2005-05-14Update FSF postal mail address.Jim Meyering
2005-05-14Update FSF postal mail address.Jim Meyering
2004-11-26(link, symlink): Remove decls.Paul Eggert
2004-09-21Remove unused "case 0".Paul Eggert
2004-09-13Adjust to backup enum rename.Paul Eggert
2004-08-03(symbolic_link, interactive, remove_existing_files,Paul Eggert
verbose, hard_dir_link, dereference_dest_dir_symlinks, do_link, main): Use bool for booleans.
2004-07-27(do_link): find_backup_file_name no longer returns NULL, so don'tPaul Eggert
bother to check for this.
2004-07-02Add short names -t and -T for --target-directoryJim Meyering
and --no-target-directory options, respectively. (NO_TARGET_DIRECTORY_OPTION, TARGET_DIRECTORY_OPTION): Remove. All uses changed to 'T' and 't', respectively. (long_options, main, usage): Add -t and -T as aliases for --target-directory and --no-target-directory, respectively.
2004-06-30Add support for --no-target-directory option.Jim Meyering
(NO_TARGET_DIRECTORY_OPTION): New constant. (long_options, usage, main): Add support for
2004-06-28 Use more-consistent rules among cp, ln, and mv when dealing withJim Meyering
last operands that are (or look like) directories. * src/cp.c (target_directory_operand): New, nearly-common function, It reports an error if the destination appears to be a directory (e.g., because it has a trailing slash) but is not. * src/ln.c, src/mv.c: Likewise. * src/cp.c (do_copy): Use it. * src/ln.c (main): Likewise. * src/mv.c (main): Likewise. * src/cp.c (do_copy): Don't output a usage message because of file problems (e.g., an operand is not a directory). Use it only for syntax. Standardize on "target %s is not a directory" for the diagnostic. * src/ln.c (main): Likewise. * src/mv.c (main): Likewise. * src/cp.c (do_copy): Remove test for trailing slash, since target_directory_operand now does this. * src/ln.c (main): Likewise. * src/mv.c (movefile): Likewise. * src/cp.c (main): Reject multiple target directories. Check whether a specified target is a directory when parsing the options, using stat. This gives more-accurate diagnostics. * src/ln.c (main): Likewise. * src/ln.c (isdir): Remove decl; no longer needed. * src/mv.c (isdir, lstat): Likewise. * src/ln.c (do_link): New arg dest_is_dir. All uses changed. Don't check the destination ourself; rely on dest_is_dir. This way we can avoid lstatting the destination in the usual case, and in the worst case we lstat 1, not 3 times. Don't bother to unlink unless link failed; this saves a syscall. Remove unnecessary backup_succeeded flag; it was identical to "dest_backup != NULL". * src/ln.c (main): Use int to count to argc, not unsigned int. This handles negative operand counts. * src/mv.c (main): Likewise.
2004-06-27Fix a bug: formerly, if d/x was a directory and x a file, "ln xJim Meyering
d/" incorrectly created a link d/x/x. It also saves some system calls. (main): Don't append basename to dest if this results in an existing directory name.
2004-06-25(do_link): Remove unnecessary call to lstat.Jim Meyering
(main): Avoid subscript error when the destination is "".
2004-06-21(main): Standardize on the diagnostics given when someone givesJim Meyering
too few operands ("missing operand after `xxx'") or too many operands ("extra operand `xxx'"). Include "quote.h" and/or "error.h" if it wasn't already being included.
2004-06-20Remove declaration of yesno.Jim Meyering
Instead, include yesno.h.
2004-04-27(backup_type): Declare `static'.Jim Meyering
2004-01-21(usage): Use EXIT_SUCCESS, not 0, for clarity.Jim Meyering
(usage): Don't bother normalizing exit status since the arg is already the correct exit status now.
2003-10-18Most .c files (AUTHORS): Revert the WRITTEN_BY/AUTHORS changeJim Meyering
of 2003-09-19. Now, AUTHORS is a comma-separated list of strings. Update the call to parse_long_options so that `AUTHORS, NULL' are the last parameters. * src/true.c (main): Append NULL to version_etc argument list. * src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
2003-10-15(usage): Clarify that --directory, -d, -F probably won'tJim Meyering
work even for superuser. Suggestion from Dan Jacobson.
