* diff: adjust ANSI escapes for compatibility with less -RDennis Lambe Jr2018-12-301-0/+4
| | | | | | | | | | | | | | | | | | | | GNU less can display ANSI-colored text with the -R flag, but this support has some limitations. One of them is that if an escape sequence starts on one line and ends on a different line, only the first line will be colored in less. As a result, when diff creates colored output with multi-line deletes or adds, less will only color the first line. This change resets ANSI color to the default at the end of each line and restarts it at the beginning of the next. It patches normal and context mode. Side-by-side already worked in my testing. * src/context.c (print_context_label, pr_context_hunk): As above. (pr_unidiff_hunk, print_context_header): Likewise. * src/normal.c (print_normal_hunk): Likewise. * tests/colors: Adjust existing tests to accommodate this. * NEWS (Improvements): Mention it. Proposed in http://bugs.gnu.org/31105

* cmp: report prefix length when one file is shorterPaul Eggert2017-05-041-0/+5
| | | | | | | | | Requested by Dan Jacobson (Bug#22816). * NEWS: * doc/diffutils.texi (Invoking cmp, cmp Options): Document this. * src/cmp.c (cmp): Implement it. * tests/Makefile.am (TESTS): Add cmp. * tests/cmp: New file.

| | | | | | * NEWS (Bug fixes): Describe it. * tests/invalid-re: New test for just-fixed bug. * tests/Makefile.am (TESTS): Add it.

| | | | * NEWS: Update. Also, thanks to Nelson Beebe for reporting this.
* diff: avoid UMR with ---presume-output-ttyJim Meyering2017-01-311-0/+3
| | | | | | | * src/diff.c (main): Always define presume_output_tty. Otherwise, it would be read uninitialized. Introduced in v3.3-45-g17e2698 * NEWS (Bug fixes): Mention it.
* maint: change "time stamp" to "timestamp" globallyJim Meyering2017-01-311-2/+2
| | | | | | | | This avoids a new syntax-check failure. * ChangeLog-2008: Perform that change. * doc/diffutils.texi: Likewise. * NEWS: Likewise. * cfg.mk: Update the old news hash accordingly.

* diff: fix big performance degradation in 3.4Paul Eggert2016-10-251-0/+5
| | | | | | | | | * NEWS, doc/diffutils.texi (Overview): Document this. * src/analyze.c (diff_2_files): Restore too_expensive heuristic, but this time with a floor that is 16 times the old floor. This should fix Bug#16848, by generating good-quality output for its test case, while not introducing Bug#24715, by running nearly as fast as diff-3.3 for that test case.
* diff: port line numbers to mingw64Paul Eggert2016-08-271-0/+4
| | | | | | | | Problem reported by Peter Rosin (Bug#24311). * src/system.h (printint, pI): New typedef and macro. All uses of 'long int' and "%l" in printf format replaced by 'printint' and "%"pI respectively. * src/ifdef.c (do_printf_spec): Don't assume pI is length 1.

| | | | | | | | | | Commit v3.3-42-g3b74a90, "FIXME: src/diff3: plug a leak" added an invalid use of free, leading to use-after-free in nearly any invocation of diff3. Revert that commit. * NEWS (Bug fixes): Mention it. * tests/diff3: New file, to add minimal test coverage. * tests/Makefile.am (TESTS): Add it. Reported by Bastian Beischer in http://bugs.gnu.org/24210
* diff: disable colorization for TERM=dumbJim Meyering2016-08-081-0/+4
| | | | | | | | * src/diff.c (main): With --color or --color=auto, when TERM is "dumb", disable colorization. Suggested by Daniel Colascione. * NEWS (Bug fixes): Mention it. * tests/colors: Add a test that would fail without this change, yet passes with it.

* diff --brief no longer mistakenly reports diff. with 0-sized /proc/ filesJim Meyering2015-12-061-0/+7
| | | | | | | | | | | | | | | | Normally, it is safe to assume two regular files are different when their st_size values are different. However, that assumption may be invalid if either value is zero, as happens with files on Linux /proc and /sys file systems. Since skipping this optimization will usually cost very little (one read syscall, to read zero bytes), it is fine to accommodate those unusual files. * src/analyze.c (diff_2_files): Do not assume regular files differ just because their st_size values differ when one or more is 0. * src/diff.c (compare_files): Likewise. * tests/brief-vs-proc-stat-zero: New test. * tests/Makefile.am: Add it. * NEWS (Bug fixes): Describe it.

* diff: remove TOO_EXPENSIVE heuristicPaul Eggert2014-02-231-0/+7
| | | | | | | | | | | | | Problem reported by Vincent Lefevre in <http://bugs.gnu.org/16848>. The simplest solution is to remove the TOO_EXPENSIVE heuristic that I added to GNU diff in 1993. Although appropriate for circa-1993 hardware, these days the heuristic seems to be more trouble than it's worth. * NEWS: Document this. * doc/diffutils.texi (Overview): Modernize citations. Remove mention of TOO_EXPENSIVE heuristic. * src/analyze.c (diff_2_files): Adjust to TOO_EXPENSIVE-related API changes in gnulib's diffseq module.

| | | | | | | | | Problem reported by Vincent Lefevre in <http://bugs.gnu.org/16608>. * NEWS: * doc/diffutils.texi (Binary, Invoking diff): Document this. * src/analyze.c (briefly_report): Return void, not int. All uses changed. Do not futz with exit status. Simplify. * tests/binary: Adjust to match new behavior.

| | | | | | | | | | | | Problem reported by Errembault Philippe in: http://lists.gnu.org/archive/html/bug-diffutils/2013-03/msg00012.html * NEWS: Document this. * src/dir.c (compare_names): Fall back on file_name_cmp if compare_collated returns 0, unless ignoring file name case. (diff_dirs): Don't bother with the O(N**2) stuff unless ignoring file name case. * tests/Makefile.am (TESTS): Add strcoll-0-names. * tests/strcoll-0-names: New file.
