2019-05-13difftool: fallback on merge.guitoolLibravatar Denton Liu1-0/+16
In git-difftool.txt, it says 'git difftool' falls back to 'git mergetool' config variables when the difftool equivalents have not been defined. However, when `diff.guitool` is missing, it doesn't fallback to anything. Make git-difftool fallback to `merge.guitool` when `diff.guitool` is missing.

2019-03-18difftool: allow running outside Git worktrees with --no-indexLibravatar Johannes Schindelin1-0/+10
As far as this developer can tell, the conversion from a Perl script to a built-in caused the regression in the difftool that it no longer runs outside of a Git worktree (with `--no-index`, of course). It is a bit embarrassing that it took over two years after retiring the Perl version to discover this regression, but at least we now know, and can do something, about it.

2019-01-27parse-options: disable option abbreviation with PARSE_OPT_KEEP_UNKNOWNLibravatar Nguyễn Thái Ngọc Duy1-2/+2
parse-options can unambiguously find an abbreviation only if it sees all available options. This is usually the case when you use parse_options(). But there are other callers like blame or shortlog which uses parse_options_start() in combination with a custom option parser, like rev-list. parse-options cannot see all options in this case and will get abbrev detection wrong. Disable it. t7800 needs update because --symlink no longer expands to --symlinks and will be passed down to git-diff, which will not recognize it. I still think this is the correct thing to do. But if --symlink has been actually used in the wild, we would just add an option alias for it.

The GETTEXT_POISON=YesPlease compile-time testing option added in my bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly translator", 2011-02-22) has been slowly bitrotting as strings have been marked for translation, and new tests have been added without running it. I brought this up on the list ("[BUG] test suite broken with GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at all anymore. At least one person occasionally uses it, and Lars Schneider offered to change one of the the Travis builds to run in this mode, so fix up the failing ones. My test setup runs most of the tests, with the notable exception of skipping all the p4 tests, so it's possible that there's still some lurking regressions I haven't fixed. 1. <CACBZZX62+acvi1dpkknadTL827mtCm_QesGSZ=6+UnyeMpg8+Q@mail.gmail.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-04-13difftool: fix use-after-freeLibravatar Johannes Schindelin1-0/+19
The left and right base directories were pointed to the buf field of two strbufs, which were subject to change. A contrived test case shows the problem where a file with a long enough name to force the strbuf to grow is up-to-date (hence the code path is used where the work tree's version of the file is reused), and then a file that is not up-to-date needs to be written (hence the code path is used where checkout_entry() uses the previously recorded base_dir that is invalid by now). Let's just copy the base_dir strings for use with checkout_entry(), never touch them until the end, and release them then. This is an easily verifiable fix (as opposed to the next-obvious alternative: to re-set base_dir after every loop iteration).

2016-12-08difftool: fix dir-diff index creation when in a subdirectoryLibravatar David Aguilar1-3/+41
9ec26e7977 (difftool: fix argument handling in subdirs, 2016-07-18) corrected how path arguments are handled in a subdirectory, but it introduced a regression in how entries outside of the subdirectory are handled by dir-diff. When preparing the right-side of the diff we only include the changed paths in the temporary area. The left side of the diff is constructed from a temporary index that is built from the same set of changed files, but it was being constructed from within the subdirectory. This is a problem because the indexed paths are toplevel-relative, and thus they were not getting added to the index. Teach difftool to chdir to the toplevel of the repository before preparing its temporary indexes. This ensures that all of the toplevel-relative paths are valid. Add test cases to more thoroughly exercise this scenario. Reported-by: Frank Becker <fb@mooflu.com> Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-08-15difftool: always honor fatal error exit codesLibravatar John Keeping1-0/+6
At the moment difftool's "trust exit code" logic always suppresses the exit status of the diff utility we invoke. This is useful because we don't want to exit just because diff returned "1" because the files differ, but it's confusing if the shell returns an error because the selected diff utility is not found. POSIX specifies 127 as the exit status for "command not found", 126 for "command found but is not executable" and values greater than 128 if the command terminated because it received a signal [1] and at least bash and dash follow this specification, while diff utilities generally use "1" for the exit status we want to ignore. Handle any value of 126 or greater as a special value indicating that some form of fatal error occurred.

2016-01-28mingw: work around pwd issues in the testsLibravatar Johannes Schindelin1-7/+7
In Git for Windows' SDK, the tests are run using a Bash that relies on the POSIX emulation layer MSYS2 (itself a friendly fork of Cygwin). As such, paths in tests can be POSIX paths. As soon as those paths are passed to git.exe (which does *not* use the POSIX emulation layer), those paths are converted into Windows paths, though. This happens for command-line parameters, but not when reading, say, config variables. To help with that, the `pwd` command is overridden to return the Windows path of the current working directory when testing Git on Windows. However, when talking to anything using the POSIX emulation layer, it is really much better to use POSIX paths because Windows paths contain a colon after the drive letter that will easily be mistaken for the common separator in path lists. So let's just use the $PWD variable when the POSIX path is needed. This lets t7800-difftool.sh, t9400-git-cvsserver-server.sh, t9402-git-cvsserver-refs.sh and t9401-git-cvsserver-crlf.sh pass in Git for Windows' SDK. Note: the cvsserver tests require not only the `cvs` package (install it into Git for Windows' SDK via `pacman -S cvs`) but also the Perl SQLite bindings (install them into Git for Windows' SDK via `cpan DBD::SQLite`).

The code to prepare the working tree side of temporary directory for the "dir-diff" feature forgot that symbolic links need not be copied (or symlinked) to the temporary area, as the code already special cases and overwrites them. Besides, it was wrong to try computing the object name of the target of symbolic link, which may not even exist or may be a directory. * da/difftool: difftool: ignore symbolic links in use_wt_file
2015-10-29difftool: ignore symbolic links in use_wt_fileLibravatar David Aguilar1-0/+19
The caller is preparing a narrowed-down copy of the working tree and this function is asked if the path should be included in that copy. If we say yes, the path from the working tree will be either symlinked or copied into the narrowed-down copy. For any path that is a symbolic link, the caller later fixes up the narrowed-down copy by unlinking the path and replacing it with a regular file it writes out that mimics the way how "git diff" compares symbolic links. Let's answer "no, you do not want to copy/symlink the working tree file" for all symbolic links from this function, as we know the result will not be used because it will be overwritten anyway. Incidentally, this also stops the function from feeding a symbolic link in the working tree to hash-object, which is a wrong thing to do to begin with. The link may be pointing at a directory, or worse may be dangling (both would be noticed as an error). Even if the link points at a regular file, hashing the contents of a file that is pointed at by the link is not correct (Git hashes the contents of the link itself, not the pointee).

2014-04-21run_external_diff: clean up error handlingLibravatar Jeff King1-1/+1
When the external diff reports an error, we try to clean up and die. However, we can make this process a bit simpler: 1. We do not need to bother freeing memory, since we are about to exit. Nor do we need to clean up our tempfiles, since the atexit() handler will do it for us. So we can die as soon as we see the error. 3. We can just call die() rather than fprintf/exit. This does technically change our exit code, but the exit code of "1" is not meaningful here. In fact, it is probably wrong, since "1" from diff usually means "completed successfully, but there were differences". And while we're there, we can mark the error message for translation, and drop the full stop at the end to make it more like our other messages.

2013-03-29difftool: don't overwrite modified filesLibravatar John Keeping1-0/+30
After running the user's diff tool, git-difftool will copy any files that differ between the working tree and the temporary tree. This is useful when the user edits the file in their diff tool but is wrong if they edit the working tree file while examining the diff. Instead of copying unconditionally when the files differ, create and index from the working tree files and only copy the temporary file back if it was modified and the working tree file was not. If both files have been modified, print a warning and exit with an error. Note that we cannot use an existing index in git-difftool since those contain the modified files that need to be checked out but here we are looking at those files which are copied from the working tree and not checked out.

073678b8e6324a155fa99f40eee0637941a70a34 reworked the mergetools/ directory so that every file corresponds to a difftool-supported tool. When this happened the "defaults" file went away as it was no longer needed by mergetool--lib. t7800 tests that configured commands can override builtins, but this test was not adjusted when the "defaults" file was removed because the test continued to pass. Adjust the test to use the everlasting "vimdiff" tool name instead of "defaults" so that it correctly tests against a tool that is known by mergetool--lib.

2013-02-20t7800: modernize testsLibravatar David Aguilar1-198/+168
Eliminate a lot of redundant work by using test_config(). Catch more return codes by more use of temporary files and test_cmp. The original tests relied upon restore_test_defaults() from the previous test to provide the next test with a sane environment. Make the tests do their own setup so that they are not dependent on the success of the previous test. The end result is shorter tests and better test isolation.
