2019-10-28t4027: make hash-size independentbrian m. carlson
Instead of hard-coding the length of an object ID, look this value up using the translation tables. Similarly, compute input data for invalid submodule entries using the tables as well. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-08-21tests: use 'test_must_be_empty' instead of 'test_cmp <empty> <out>'SZEDER Gábor
Using 'test_must_be_empty' is shorter and more idiomatic than >empty && test_cmp empty out as it saves the creation of an empty file. Furthermore, sometimes the expected empty file doesn't have such a descriptive name like 'empty', and its creation is far away from the place where it's finally used for comparison (e.g. in 't7600-merge.sh', where two expected empty files are created in the 'setup' test, but are used only about 500 lines later). These cases were found by instrumenting 'test_cmp' to error out the test script when it's used to compare empty files, and then converted manually. Note that even after this patch there still remain a lot of cases where we use 'test_cmp' to check empty files: - Sometimes the expected output is not hard-coded in the test, but 'test_cmp' is used to ensure that two similar git commands produce the same output, and that output happens to be empty, e.g. the test 'submodule update --merge - ignores --merge for new submodules' in 't7406-submodule-update.sh'. - Repetitive common tasks, including preparing the expected results and running 'test_cmp', are often extracted into a helper function, and some of this helper's callsites expect no output. - For the same reason as above, the whole 'test_expect_success' block is within a helper function, e.g. in 't3070-wildmatch.sh'. - Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update (-p)' in 't9400-git-cvsserver-server.sh'.

2018-08-21tests: use 'test_must_be_empty' instead of '! test -s'SZEDER Gábor
Using 'test_must_be_empty' is preferable to '! test -s', because it gives a helpful error message if the given file is unexpectedly not empty, while the latter remains completely silent. Furthermore, it also catches cases when the given file unexpectedly does not exist at all. This patch was basically created by: sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh with the following notable exceptions: - The '! test -s' check in '.gitmodules ignore=dirty suppresses submodules with untracked content' in 't7508-status.sh' is left as-is, because it's bogus and, therefore, it's subject of a dedicated patch. - The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and 't9135-git-svn-moved-branch-empty-file.sh' are immediately preceeded by a 'test -f' to ensure that the files exist in the first place. 'test_must_be_empty' ensures that as well, so those 'test -f' commands are removed as well. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-08-03diff: stop allowing diff to have submodules configured in .git/configBrandon Williams
Traditionally a submodule is comprised of a gitlink as well as a corresponding entry in the .gitmodules file. Diff doesn't follow this paradigm as its config callback routine falls back to populating the submodule-config if a config entry starts with 'submodule.'. Remove this behavior in order to be consistent with how the submodule-config is populated, via calling 'gitmodules_config()' or 'repo_read_gitmodules()'.

2010-08-09Submodules: Use "ignore" settings from .gitmodules too for diff and statusJens Lehmann
The .gitmodules file is parsed for "submodule.<name>.ignore" entries before looking for them in .git/config. Thus settings found in .git/config will override those from .gitmodules, thereby allowing the local developer to ignore settings given by the remote side while also letting upstream set defaults for those users who don't have special needs.

2010-08-09Submodules: Add the new "ignore" config option for diff and statusJens Lehmann
The new "ignore" config option controls the default behavior for "git status" and the diff family. It specifies under what circumstances they consider submodules as modified and can be set separately for each submodule. The command line option "--ignore-submodules=" has been extended to accept the new parameter "none" for both status and diff. Users that chose submodules to get rid of long work tree scanning times might want to set the "dirty" option for those submodules. This brings back the pre 1.7.0 behavior, where submodule work trees were never scanned for modifications. By using "--ignore-submodules=none" on the command line the status and diff commands can be told to do a full scan. This option can be set to the following values (which have the same name and meaning as for the "--ignore-submodules" option of status and diff): "all": All changes to the submodule will be ignored. "dirty": Only differences of the commit recorded in the superproject and the submodules HEAD will be considered modifications, all changes to the work tree of the submodule will be ignored. When using this value, the submodule will not be scanned for work tree changes at all, leading to a performance benefit on large submodules. "untracked": Only untracked files in the submodules work tree are ignored, a changed HEAD and/or modified files in the submodule will mark it as modified. "none" (which is the default): Either untracked or modified files in a submodules work tree or a difference between the subdmodules HEAD and the commit recorded in the superproject will make it show up as changed. This value is added as a new parameter for the "--ignore-submodules" option of the diff family and "git status" so the user can override the settings in the configuration.

2010-06-25t4027,4041: Use test -s to test for an empty fileBrian Gernhardt
The tests used a mixture of 'echo -n' (which is non-portable) and either test_cmp or diff to check if a file is empty. The much easier and portable method to check for an empty file is '! test -s' While we're in t4027, there was an excess test_done. Remove it.

2010-06-11Add optional parameters to the diff option "--ignore-submodules"Jens Lehmann
In some use cases it is not desirable that the diff family considers submodules that only contain untracked content as dirty. This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree. An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved.

2010-01-17Teach diff that modified submodule directory is dirtyJunio C Hamano
A diff run in superproject only compares the name of the commit object bound at the submodule paths. When we compare with a work tree and the checked out submodule directory is dirty (e.g. has either staged or unstaged changes, or has new files the user forgot to add to the index), show the work tree side as "dirty".

2009-04-29diff -c -p: do not die on submodulesJunio C Hamano
The combine diff logic knew only about blobs (and their checked-out form in the work tree, either regular files or symlinks), and barfed when fed submodules. This "externalizes" gitlinks in the same way as the normal patch generation codepath does (i.e. "Subproject commit Xxx\n") to fix the issue. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-08-17tests: use $TEST_DIRECTORY to refer to the t/ directoryJunio C Hamano
Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can refer to t/ directory reliably. This finally makes all the tests use it to refer to the outside environment. With this patch, and a one-liner not included here (because it would contradict with what Dscho really wants to do): | diff --git a/t/test-lib.sh b/t/test-lib.sh | index 70ea7e0..60e69e4 100644 | --- a/t/test-lib.sh | +++ b/t/test-lib.sh | @@ -485,7 +485,7 @@ fi | . ../GIT-BUILD-OPTIONS | | # Test repository | -test="trash directory" | +test="trash directory/another level/yet another" | rm -fr "$test" || { | trap - exit | echo >&5 "FATAL: Cannot prepare test area" all the tests still pass, but we would want extra sets of eyeballs on this type of change to really make sure.

2008-05-05diff: a submodule not checked out is not modifiedJunio C Hamano
948dd34 (diff-index: careful when inspecting work tree items, 2008-03-30) made the work tree check careful not to be fooled by a new directory that exists at a place the index expects a blob. For such a change to be a typechange from blob to submodule, the new directory has to be a repository. However, if the index expects a submodule there, we should not insist the work tree entity to be a repository --- a simple directory that is not a full fledged repository (even an empty directory would do) should be considered an unmodified subproject, because that is how a superproject with a submodule is checked out sparsely by default. This makes the function check_work_tree_entity() even more careful not to report a submodule that is not checked out as removed. It fixes the recently added test in t4027.

2008-03-13add test_cmp function for test scriptsJeff King
Many scripts compare actual and expected output using "diff -u". This is nicer than "cmp" because the output shows how the two differ. However, not all versions of diff understand -u, leading to unnecessary test failure. This adds a test_cmp function to the test scripts and switches all "diff -u" invocations to use it. The function uses the contents of "$GIT_TEST_CMP" to compare its arguments; the default is "diff -u". On systems with a less-capable diff, you can do: GIT_TEST_CMP=cmp make test Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-03-02diff: make sure work tree side is shown as 0{40} when differentJunio C Hamano
Ping Yin noticed that "git diff-index --raw" shows 0{40} when work tree has submodule difference, but "git diff --raw" didn't correctly do so. There was a mistake in the diffcore_skip_stat_unmatch() that was meant to clean up the stat-only difference for running diff between the index and work tree and diff between the tree and the work tree, to cause it re-read from the submodule repository HEAD. When ce_stat_match() says work tree is different, we should always say 0{40} on the work tree side. This patch fixes the issue, and adds tests. Signed-off-by: Junio C Hamano <gitster@pobox.com>
