2023-11-02tests: teach callers of test_i18ngrep to use test_grepJunio C Hamano
They are equivalents and the former still exists, so as long as the only change this commit makes are to rewrite test_i18ngrep to test_grep, there won't be any new bug, even if there still are callers of test_i18ngrep remaining in the tree, or when merged to other topics that add new uses of test_i18ngrep. This patch was produced more or less with git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' | xargs perl -p -i -e 's/test_i18ngrep /test_grep /' and a good way to sanity check the result yourself is to run the above in a checkout of c4603c1c (test framework: further deprecate test_i18ngrep, 2023-10-31) and compare the resulting working tree contents with the result of applying this patch to the same commit. You'll see that test_i18ngrep in a few t/lib-*.sh files corrected, in addition to the manual reproduction. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-04-06mergetool: new config guiDefault supports auto-toggling gui by DISPLAYTao Klerks
When no merge.tool or diff.tool is configured or manually selected, the selection of a default tool is sensitive to the DISPLAY variable; in a GUI session a gui-specific tool will be proposed if found, and otherwise a terminal-based one. This "GUI-optimizing" behavior is important because a GUI can make a huge difference to a user's ability to understand and correctly complete a non-trivial conflicting merge. Some time ago the merge.guitool and diff.guitool config options were introduced to enable users to configure both a GUI tool, and a non-GUI tool (with fallback if no GUI tool configured), in the same environment. Unfortunately, the --gui argument introduced to support the selection of the guitool is still explicit. When using configured tools, there is no equivalent of the no-tool-configured "propose a GUI tool if we are in a GUI environment" behavior. As proposed in <xmqqmtb8jsej.fsf@gitster.g>, introduce new configuration options, difftool.guiDefault and mergetool.guiDefault, supporting a special value "auto" which causes the corresponding tool or guitool to be selected depending on the presence of a non-empty DISPLAY value. Also support "true" to say "default to the guitool (unless --no-gui is passed on the commandline)", and "false" as the previous default behavior when these new configuration options are not specified.

2022-10-01t/t7NNN: allow local submodulesTaylor Blau
To prepare for the default value of `protocol.file.allow` to change to "user", ensure tests that rely on local submodules can initialize them over the file protocol. Tests that only need to interact with submodules in a limited capacity have individual Git commands annotated with the appropriate configuration via `-c`. Tests that interact with submodules a handful of times use `test_config_global` instead. Test scripts that rely on submodules throughout use a `git config --global` during a setup test towards the beginning of the script. Signed-off-by: Taylor Blau <me@ttaylorr.com>

* da/difftool-dir-diff-symlink-fix: difftool: fix symlink-file writing in dir-diff mode
2021-09-23difftool: fix symlink-file writing in dir-diff modeDavid Aguilar
The difftool dir-diff mode handles symlinks by replacing them with their readlink(2) values. This allows diff tools to see changes to symlinks as if they were regular text diffs with the old and new path values. This is analogous to what "git diff" displays when symlinks change. The temporary diff directories that are created initially contain symlinks because they get checked-out using a temporary index that retains the original symlinks as checked-in to the repository. A bug was introduced when difftool was rewritten in C that made difftool write the readlink(2) contents into the pointed-to file rather than the symlink itself. The write was going through the symlink and writing to its target rather than writing to the symlink path itself. Replace symlinks with raw text files by unlinking the symlink path before writing the readlink(2) content into them. When 18ec800512 (difftool: handle modified symlinks in dir-diff mode, 2017-03-15) added handling for modified symlinks this bug got recorded in the test suite. The tests included the pointed-to symlink target paths. These paths were being reported because difftool was erroneously writing to them, but they should have never been reported nor written. Correct the modified-symlinks test cases by removing the target files from the expected output. Add a test to ensure that symlinks are written with the readlink(2) values and that the target files contain their original content.

2020-11-20tests: mark tests relying on the current default for `init.defaultBranch`Johannes Schindelin
In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9]*.sh) \ t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests. The reason? `git p4` stores the (foreign) remote branch in the branch called `p4/master`, which is obviously not the default branch. Manual analysis revealed that only five of these tests actually require a specific default branch name to pass; They were modified thusly: $ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' t/t980[0167]*.sh t/t9811*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In https://github.com/git-for-windows/git/issues/2677, a `git difftool -d` problem was reported. The underlying cause was a bug in `git diff-files --raw` that we just fixed: it reported intent-to-add files with the empty _tree_ as the post-image OID, when we need to show an all-zero (or, "null") OID instead, to indicate to the caller that they have to look at the worktree file. The symptom of that problem shown by `git difftool` was this: error: unable to read sha1 file of <path> (<empty-tree-OID>) error: could not write '<filename>' Make sure that the reported `difftool` problem stays fixed.

2020-01-17t7800: don't rely on reuse_worktree_file()Jeff King
A test in t7800 tries to make sure that when git-difftool runs an external tool that fails, it stops looking at files. Our fake failing tool prints the file name it was asked to diff before exiting non-zero, and then we confirm the output contains only that file. However, this subtly relies on our internal reuse_worktree_file(). Because we're diffing between branches, the command run by difftool might see: - the git-stored filename (e.g., "file"), if we decided that the working tree contents were up-to-date with the object in the index and HEAD, and we could reuse them - a temporary filename (e.g. "/tmp/abc123_file") if we had to dump the contents from the object database If the latter case happens, then the test fails, because it's expecting the string "file". I discovered this when debugging something unrelated with reuse_worktree_file(). I _thought_ it should be able to be triggered by a racy-git situation, but running: ./t7800-difftool.sh --stress --run=2,13 never seems to fail. However, by my reading of reuse_worktree_file(), this would probably always fail under Cygwin, because it sets NO_FAST_WORKING_DIRECTORY. At any rate, since reuse_worktree_file() is meant to be an optimization that may or may not trigger, our test should be robust either way. Instead of checking the filename, let's just make sure we got a single line of output (which would not be true if we continued after the first failure).

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.

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).

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>
2016-08-16difftool: always honor fatal error exit codesJohn Keeping
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.

Add a test to ensure that difftool's dir-diff feature works when these variables are present in the environment.

2016-07-11Merge branch 'ak/t7800-wo-readlink' into maintJunio C Hamano
One among four invocations of readlink(1) in our test suite has been rewritten so that the test can run on systems without the command (others are in valgrind test framework and t9802). * ak/t7800-wo-readlink: t7800: readlink may not be available
2016-06-21t7800: readlink may not be availableArmin Kunaschik
The readlink(1) command is not available on all platforms (notably not on AIX and HP-UX) and can be replaced in this test with the "workaround" ls -ld <name> | sed -e 's/.* -> //' This is no universal readlink replacement but works in the controlled test environment well enough.

2016-05-24Merge branch 'da/difftool'Junio C Hamano
"git difftool" learned to handle unmerged paths correctly in dir-diff mode. * da/difftool: difftool: handle unmerged files in dir-diff mode difftool: initialize variables for readability
2016-05-17difftool: handle unmerged files in dir-diff modeDavid Aguilar
When files are unmerged they can show up as both unmerged and modified in the output of `git diff --raw`. This causes difftool's dir-diff to create filesystem entries for the same path twice, which fails when it encounters a duplicate path. Ensure that each worktree path is only processed once. Add a test to demonstrate the breakage. Reported-by: Jan Smets <jan@smets.cx> Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

UI consistency improvements. * nf/mergetool-prompt: difftool/mergetool: make the form of yes/no questions consistent
2016-04-26difftool/mergetool: make the form of yes/no questions consistentNikola Forró
Every yes/no question in difftool/mergetool scripts has slightly different form, and none of them is consistent with the form git itself uses. Make the form of all the questions consistent with the form used by git.

2016-01-29mingw: work around pwd issues in the testsJohannes Schindelin
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`). This patch is based on earlier work by 마누엘 and Karsten Blees. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
