* New option --no-dereference.Bruno Haible2012-01-081-4/+70
| | | | | | | | | | | | | | | * src/diff.h (no_dereference_symlinks): New variable. * src/diff.c: Include xreadlink.h. (longopts): Add --no-dereference option. (main): Accept --no-dereference option. (option_help_msgid): Mention the --no-dereference option. (compare_files): If no_dereference_symlinks is true, use lstat() instead of stat().

| | | | | | | * src/diff.c: Include binary-io.h, not xfreopen.h. (main): Use SET_BINARY (...) rather than xfreopen (NULL, X, ...), because the latter doesn't work on MinGW and crashes using MSVC. * src/cmp.c (main): Likewise.

* portability: avoid "diff - ..." failure at least on *BSD and SolarisJim Meyering2010-02-101-1/+1
| | | | | | | The new "stdin" test was failing on many types of systems. * src/diff.c (compare_files): Guard use of xfreopen (NULL, "rb", ... also with O_BINARY, so as to avoid this unnecessary call on systems where it's not needed (on some it fails with "Bad address".

* maint: add an assertion to suppress clang-detected warningJim Meyering2009-11-201-2/+6
| | | | | | | | The clang static analyzer reported that a NULL parent could be dereferenced. However, that cannot happen, because for all callers, the parameter, parent, is always non-NULL at that point. * src/diff.c: Include <assert.h>. Assert that parent is not NULL.

(GDIFF_MAIN): Remove. All uses removed. (function_regexp_list, ignore_regexp_list): No longer static; now locals in 'main'. (main): Set opt.function_regexp, opt.ignore_regexp if using regexps; all other code now tests these pointers rather than inspecting fastmap internals. New local OPT to hold former statics; initialize it. (init_regexp_list): New function, used by main. (summarize_regexp_list): Now returns struct re_pattern_buffer *, and assumes reglist->regexps is not NULL. All uses changed.
* Do not include regex.h, as diff.h does this now.Paul Eggert2004-04-121-64/+78
| | | | | | | | | | | | | | | | | (option_help_msgid): Mention exit status. (main): Adjust to latest gnulib c_stack_action calling conventions. Adjust to latest version_etc calling conventions. Include <exit.h>. (binary): Define to true if not declared. (longopts): Set tabsize flag to 1. (main): Don't output nanoseconds if platform lacks them. Don't treat files as binary if !binary. (set_mtime_to_now): Use 0, not NULL. (compare_files): Mark files as nonexistent if it looks like 'patch' created inaccessible regular empty files to denote nonexistent backups. Don't compare such files. Clear st_* members of status of nonexistent file. Remove now-unnecessary tests.
* Include version-etc.h, not freesoft.h.Paul Eggert2002-06-171-8/+2
| | | | | (copyright_notice): Remove. (main): Use version_etc to print version.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Do not include signal.h. (specify_style, specify_value): Bring these routines back, as POSIX requires that the order of options not matter. (shortopts): New constant. (group_format_option, line_format_option): New constants. (LONG_OPTION, GROUP_FORMAT_OPTION, LINE_FORMAT_OPTION): New macros. (longopts): Use them. (main): 0 -> EXIT_SUCCESS, 1 -> EXIT_FAILURE, 2 -> EXIT_TROUBLE. Ensure that order of options does not matter. Check for stack overflow. If contexts overflow, substitute LIN_MAX, as that's good enough. If multiple contexts are specified, use their maximum. -c is equivalent to -C 3 now, instead of having an implicit context; likewise for -u and -U 3. Use specify_style and specify_value. (SIGCHLD): Do not define; now done in a header. Use new style time stamp format for -u / -U. Reject numeric-string options if operating in POSIX 1003.1-2001 mode. Avoid overflow problems with tab width. Simplify from-file and to-file code. (usage): Do not mention obsolete options. (filetype): Do not mention whether a file is executable. Add typed memory objects. (compare_files): 0 -> EXIT_SUCCESS, 1 -> EXIT_FAILURE, 2 -> EXIT_TROUBLE.

* (DEFAULT_WIDTH): Remove.Paul Eggert2001-12-241-11/+8
| | | | | | | | (main): Use 130 instead of DEFAULT_WIDTH, since it's not really builder-settable. Do not prepend DIFF_OPTIONS. (check-stdout): If fclose (stdout) fails, print errno info. (option_help_msgid): Default context is 3, not 2. (usage): Work even if ptrdiff_t is wider than int.
* Include dirname.h, setmode.h.Paul Eggert2001-12-111-80/+79
| | | | | | | | | | | | | | | | | (main): Later values and/or styles now silently override earlier. (specify_value, specify_style): Likewise. All callers changed. Remove. (binary, main, option_help_msgid, compare_files): HAVE_SETMODE -> HAVE_SETMODE_DOS. (NO_IGNORE_FILE_NAME_CASE_OPTION): New constant. (longopts, main, option_help_msgid): Support it. (exclude_options): New function. (main): Use it. Initialize xalloc_exit_failure before potentially allocating memory. (filetype): Distinguish executable files from others, as POSIX suggests. (compare_files): Use base_name instead of file_name_lastdirchar.

Use strtoumax instead of numeric_arg. Use specify_value when appropriate. error -> try_help when appropriate. -p now means ^[[:alpha:]$_], not ^[_a-zA-Z$]. Ignore --inhibit-hunk-merge.
