* find_identical_ends and doc/diff.texi fixesPaul Eggert2006-05-071-0/+11
|
* (find_identical_ends): Fix huge performance bug that IPaul Eggert2006-05-071-2/+3
| | | | | | | | introduced in the 2001-11-25 change: the code to remove the identical suffix also looked at the trailing sentinel, which meant the common suffix length was always incorrectly calculated to be zero. Problem and fix reported by Daniel Hipschman. Instead of his fix, revert to the (nearly-equivalent) pre-2001 code.
* Switch from GFDL 1.1 to 1.2.Paul Eggert2006-05-071-1/+1
|
* * src/system.h (PARAMS, PROTOTYPES): Remove; no longer needed.Paul Eggert2006-03-137-27/+37
| | | | | | | | | (IF_LINT): New macro, to pacify GCC. * src/analyze.c (diag, compareseq): Use IF_LINT. * src/cmp.c (cmp): Likewise. * src/diff3.c (process_diff): Likewise. Also, prefer NULL to 0. * src/ifdef.c (do_printf_spec, scan_char_literal): Likewise. * src/sdiff.c (edit): Likewise.

* (main): Avoid an unnecessary system call introduced in previous patch.Paul Eggert2006-03-091-6/+1
|
* * src/cmp.c (type_no_stdout): New constant.Paul Eggert2006-03-092-2/+18
| | | | | (main): Use it to avoid bug when the "EOF on foo" message is generated and stdout is /dev/null.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (specify_ignore_initial): Reword to avoid gcc -W warnings. (main): Use freopen instead of setmode, since freopen is in POSIX. * src/context.c: Revert most 2004-09-01 changes. Then: (TIMESPEC_NS): Remove. All uses replaced by get_stat_mtime_ns.

All uses changed. * src/dir.c (dir_read): excluded_filename renamed to excluded_file_name. * src/io.c: Don't include <setmode.h>. (sip, read_files): Remove binary file stuff, leaving a FIXME behind.
