2018-08-21tests: use 'test_must_be_empty' instead of '! test -s'Libravatar SZEDER Gábor1-3/+3
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>
2018-08-06t: factor out FUNNYNAMES as shared lazy prereqLibravatar William Chargin1-5/+3
A fair number of tests need to check that the filesystem supports file names including "funny" characters, like newline, tab, and double-quote. Jonathan Nieder suggested that this be extracted into a lazy prereq in the top-level `test-lib.sh`. This patch effects that change. The FUNNYNAMES prereq now uniformly requires support for newlines, tabs, and double-quotes in filenames. This very slightly decreases the power of some tests, which might have run previously on a system that supports (e.g.) newlines and tabs but not double-quotes, but now will not. This seems to me like an acceptable tradeoff for consistency. One test (`t/t9902-completion.sh`) defined FUNNYNAMES to further require the separators \034 through \037, the test for which was implemented using the Bash-specific $'\034' syntax. I've elected to leave this one as is, renaming it to FUNNIERNAMES. After this patch, `git grep 'test_\(set\|lazy\)_prereq.*FUNNYNAMES'` has only one result.

2017-06-23pathspec: die on empty strings as pathspecLibravatar Emily Xie1-3/+2
An empty string as a pathspec element matches all paths. A buggy script, however, could accidentally assign an empty string to a variable that then gets passed to a Git command invocation, e.g.: path=... compute a path to be removed in $path ... git rm -r "$path" which would unintentionally remove all paths in the current directory. The fix for this issue comprises of two steps. Step 1, which warns that empty strings as pathspecs will become invalid, has already been implemented in commit d426430 ("pathspec: warn on empty strings as pathspec", 2016-06-22). This patch is step 2. It removes the warning and throws an error instead.

Suppose I have a superproject 'super', with two submodules 'super/sub' and 'super/sub1'. 'super/sub' itself contains a submodule 'super/sub/subsub'. Now suppose I run, from within 'super': echo hi >sub/subsub/stray-file echo hi >sub1/stray-file Currently we get would see the following output in git-status: git status --short m sub ? sub1 With this patch applied, the untracked file in the nested submodule is displayed as an untracked file on the 'super' level as well. git status --short ? sub ? sub1 This doesn't change the output of 'git status --porcelain=1' for nested submodules, because its output is always ' M' for either untracked files or local modifications no matter the nesting level of the submodule. 'git status --porcelain=2' is affected by this change in a nested submodule, though. Without this patch it would report the direct submodule as modified and having no untracked files. With this patch it would report untracked files. Chalk this up as a bug fix. This bug fix also affects the default output (non-short, non-porcelain) of git-status, which is not tested here.

2017-03-29short status: improve reporting for submodule changesLibravatar Stefan Beller1-5/+13
If I add an untracked file to a submodule or modify a tracked file, currently "git status --short" treats the change in the same way as changes to the current HEAD of the submodule: $ git clone --quiet --recurse-submodules https://gerrit.googlesource.com/gerrit $ echo hello >gerrit/plugins/replication/stray-file $ sed -i -e 's/.*//' gerrit/plugins/replication/.mailmap $ git -C gerrit status --short M plugins/replication This is by analogy with ordinary files, where "M" represents a change that has not been added yet to the index. But this change cannot be added to the index without entering the submodule, "git add"-ing it, and running "git commit", so the analogy is counterproductive. Introduce new status letters " ?" and " m" for this. These are similar to the existing "??" and " M" but mean that the submodule (not the parent project) has new untracked files and modified files, respectively. The user can use "git add" and "git commit" from within the submodule to add them. Changes to the submodule's HEAD commit can be recorded in the index with a plain "git add -u" and are shown with " M", like today. To avoid excessive clutter, show at most one of " ?", " m", and " M" for the submodule. They represent increasing levels of change --- the last one that applies is shown (e.g., " m" if there are both modified files and untracked files in the submodule, or " M" if the submodule's HEAD has been modified and it has untracked files). While making these changes, we need to make sure to not break porcelain level 1, which shares code with "status --short". We only change "git status --short". Non-short "git status" and "git status --porcelain=2" already handle these cases by showing more detail: $ git -C gerrit status --porcelain=2 1 .M S.MU 160000 160000 160000 305c864db28eb0c77c8499bc04c87de3f849cf3c 305c864db28eb0c77c8499bc04c87de3f849cf3c plugins/replication $ git -C gerrit status [...] modified: plugins/replication (modified content, untracked content) Scripts caring about these distinctions should use --porcelain=2.

"git rm" used to refuse to remove a submodule when it has its own git repository embedded in its working tree.

2016-12-27rm: absorb a submodules git dir before deletionLibravatar Stefan Beller1-26/+17
When deleting a submodule, we need to keep the actual git directory around, such that we do not lose local changes in there and at a later checkout of the submodule we don't need to clone it again. Now that the functionality is available to absorb the git directory of a submodule, rewrite the checking in git-rm to not complain, but rather relocate the git directories inside the superproject. An alternative solution was discussed to have a function `depopulate_submodule`. That would couple the check for its git directory and possible relocation before the the removal, such that it is less likely to miss the check in the future. But the indirection with such a function added seemed also complex. The reason for that was that this possible move of the git directory was also implemented in `ok_to_remove_submodule`, such that this function could truthfully answer whether it is ok to remove the submodule. The solution proposed here defers all these checks to the caller. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-06-22pathspec: warn on empty strings as pathspecLibravatar Emily Xie1-0/+5
An empty string as a pathspec element matches all paths. A buggy script, however, could accidentally assign an empty string to a variable that then gets passed to a Git command invocation, e.g.: path=... compute a path to be removed in $path ... git rm -r "$paht" which would unintentionally remove all paths in the current directory. The fix for this issue requires a two-step approach. As there may be existing scripts that knowingly use empty strings in this manner, the first step simply gives a warning that (1) tells that an empty string will become an invalid pathspec element and (2) asks the user to use "." if they mean to match all. For step two, a follow-up patch several release cycles later will remove the warning and throw an error instead. This patch is the first step.

2015-03-20t3600: fix &&-chain breakage for setup commandsLibravatar Jeff King1-18/+18
As with the earlier patch to fix "trivial" &&-chain breakage, these missing "&&" operators are not a serious problem (e.g., we do not expect "echo" to fail). Ironically, however, inserting them shows that some of the commands _do_ fail. Specifically, some of the tests start by making sure we are at a commit with the string "content" in the file "foo". However, running "git commit" may fail because the previous test left us in that state already, and there is nothing to commit. We could remove these commands entirely, but they serve to document the test's assumptions, as well as make it robust when an earlier test has failed. We could use test_might_fail to handle all cases, but that would miss an unrelated failure to make the commit. Instead, we can just pass the --allow-empty flag to git-commit, which means that it will not complain if our setup is a noop.

The test 'choking "git rm" should not let it die with cruft' is supposed to check 'git rm's behavior when interrupted by provoking a SIGPIPE while 'git rm' is busily deleting files from a specially crafted index. This test is silently broken for the following reasons: - The test crafts a special index by feeding a large number of index entries with null shas to 'git update-index --index-info'. It was OK back then when this test was introduced in commit 0693f9ddad (Make sure lockfiles are unlocked when dying on SIGPIPE, 2008-12-18), but since commit 4337b5856f (do not write null sha1s to on-disk index, 2012-07-28) null shas are not allowed in the on-disk index causing 'git update-index' to error out. - The barfing 'git update-index --index-info' should fail the test, but it remains unnoticed because of the severely broken && chain: the test's result depends solely on whether there is a stale lock file left behind, but after 'git update-index' errors out 'git rm' won't be executed at all. To fix this test feed only non-null shas to 'git update-index' and restore the && chain (partly by adding a missing && and by using the test_when_finished helper instead of manual cleanup).

2013-08-06rm: delete .gitmodules entry of submodules removed from the work treeLibravatar Jens Lehmann1-6/+92
Currently using "git rm" on a submodule removes the submodule's work tree from that of the superproject and the gitlink from the index. But the submodule's section in .gitmodules is left untouched, which is a leftover of the now removed submodule and might irritate users (as opposed to the setting in .git/config, this must stay as a reminder that the user showed interest in this submodule so it will be repopulated later when an older commit is checked out). Let "git rm" help the user by not only removing the submodule from the work tree but by also removing the "submodule.<submodule name>" section from the .gitmodules file and stage both. This doesn't happen when the "--cached" option is used, as it would modify the work tree. This also silently does nothing when no .gitmodules file is found and only issues a warning when it doesn't have a section for this submodule. This is because the user might just use plain gitlinks without the .gitmodules file or has already removed the section by hand before issuing the "git rm" command (in which case the warning reminds him that rm would have done that for him). Only when .gitmodules is found and contains merge conflicts the rm command will fail and tell the user to resolve the conflict before trying again. Also extend the man page to inform the user about this new feature. While at it promote the submodule sub-section to a chapter as it made not much sense under "REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM". In t7610 three uses of "git rm submod" had to be replaced with "git rm --cached submod" because that test expects .gitmodules and the work tree to stay untouched. Also in t7400 the tests for the remaining settings in the .gitmodules file had to be changed to assert that these settings are missing.

2013-04-04t3600: document failure of rm across symbolic linksLibravatar Jeff King1-0/+28
If we have a symlink "d" that points to a directory, we should not be able to remove "d/f". In the normal case, where "d/f" does not exist in the index, we already disallow this, as we only remove things that git knows about in the index. So for something like: ln -s /outside/repo foo git add foo git rm foo/bar we will properly produce an error (as there is no index entry for foo/bar). However, if there is an index entry for the path (e.g., because the movement is due to working tree changes that have not yet been reflected in the index), we will happily delete it, even though the path we delete from the filesystem is not the same as the path in the index. This patch documents that failure with a test. While this is a bug, it should not be possible to cause serious data loss with it. For any path that does not have an index entry, we will complain and bail. For a path which does have an index entry, we will do the usual up-to-date content check. So even if the deleted path in the filesystem is not the same as the one we are removing from the index, we do know that they at least have the same content, and that the content is included in HEAD. That means the worst case is not the accidental loss of content, but rather confusion by the user when a copy of a file another part of the tree is removed. Which makes this bug a minor and hard-to-trigger annoyance rather than a data-loss bug (and hence the fix can be saved for a rainy day when somebody feels like working on it).

However, because unlinking "d/f" in this case will not yield ENOENT, but rather ENOTDIR, we do not notice that the file is already gone. Instead, we report it as an error. The simple solution is to treat ENOTDIR in this case exactly like ENOENT; all we want to know is whether the file is already gone, and if a leading path is no longer a directory, then by definition the sub-path is gone.

2012-11-23Teach rm to remove submodules when given with a trailing '/'Libravatar Jens Lehmann1-0/+17
Doing a "git rm submod/" on a submodule results in an error: fatal: pathspec 'submod/' did not match any files This is really inconvenient as e.g. using TAB completion in a shell on a submodule automatically adds the trailing '/' when it completes the path of the submodule directory. The user has then to remove the '/' herself to make a "git rm" succeed. Doing a "git rm -r somedir/" is working fine, so there is no reason why that shouldn't work for submodules too. Teach git rm to not error out when a '/' is appended to the path of a submodule. Achieve this by chopping off trailing slashes from the path names given if they represent directories. Add tests to make sure that logic only applies to directories and not to files. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-09-29submodule: teach rm to remove submodules unless they contain a git directoryLibravatar Jens Lehmann1-0/+343
Currently using "git rm" on a submodule - populated or not - fails with this error: fatal: git rm: '<submodule path>': Is a directory This made sense in the past as there was no way to remove a submodule without possibly removing unpushed parts of the submodule's history contained in its .git directory too, so erroring out here protected the user from possible loss of data. But submodules cloned with a recent git version do not contain the .git directory anymore, they use a gitfile to point to their git directory which is safely stored inside the superproject's .git directory. The work tree of these submodules can safely be removed without losing history, so let's teach git to do so. Using rm on an unpopulated submodule now removes the empty directory from the work tree and the gitlink from the index. If the submodule's directory is missing from the work tree, it will still be removed from the index. Using rm on a populated submodule using a gitfile will apply the usual checks for work tree modification adapted to submodules (unless forced). For a submodule that means that the HEAD is the same as recorded in the index, no tracked files are modified and no untracked files that aren't ignored are present in the submodules work tree (ignored files are deemed expendable and won't stop a submodule's work tree from being removed). That logic has to be applied in all nested submodules too. Using rm on a submodule which has its .git directory inside the work trees top level directory will just error out like it did before to protect the repository, even when forced. In the future git could either provide a message informing the user to convert the submodule to use a gitfile or even attempt to do the conversion itself, but that is not part of this change.

2010-12-14t3600-rm.sh: Don't pass a non-existent prereq to test #15Libravatar Ramsay Jones1-1/+1
Commit c91cfd19 (tests: A SANITY test prereq for testing if we're root, 2010-08-06) introduced a SANITY prerequisite which had very similar semantics to RO_DIR. That commit removed the code to set RO_DIR, but forgot to replace RO_DIR with SANITY in test #15. In order not to skip test 15 unnecessarily, since RO_DIR will never be set, we pass the SANITY prerequisite instead.

2010-08-18tests: A SANITY test prereq for testing if we're rootLibravatar Ævar Arnfjörð Bjarmason1-16/+0
Some tests depend on not being able to write to files after chmod -w. This doesn't work when running the tests as root. Change test-lib.sh to test if this works, and if so it sets a new SANITY test prerequisite. The tests that use this previously failed when run under root. There was already a test for this in t3600-rm.sh, added by Junio C Hamano in 2283645 in 2006. That check now uses the new SANITY prerequisite.

2010-02-18rm: fix bug in recursive subdirectory removalLibravatar Jeff King1-0/+8
If we remove a path in a/deep/subdirectory, we should try to remove as many trailing components as possible (i.e., subdirectory, then deep, then a). However, the test for the return value of rmdir was reversed, so we only ever deleted at most one level. The fix is in remove_path, so "apply" and "merge-recursive" also are fixed.

There are two prerequisites: - The filesystem supports names with tabs or new-lines. - Files cannot be removed if their containing directory is read-only. Previously, whether these preconditions are satisified was tested inside test_expect_success. We move these tests outside because, strictly speaking, they are not part of the tests.

2008-11-28git add --intent-to-add: fix removal of cached emptinessLibravatar Junio C Hamano1-2/+2
This uses the extended index flag mechanism introduced earlier to mark the entries added to the index via "git add -N" with CE_INTENT_TO_ADD. The logic to detect an "intent to add" entry for the purpose of allowing "git rm --cached $path" is tightened to check not just for a staged empty blob, but with the CE_INTENT_TO_ADD bit. This protects an empty blob that was explicitly added and then modified in the work tree from being dropped with this sequence: $ >empty $ git add empty $ echo "non empty" >empty $ git rm --cached empty Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-10-22rm: loosen safety valve for empty filesLibravatar Jeff King1-0/+13
If a file is different between the working tree copy, the index, and the HEAD, then we do not allow it to be deleted without --force. However, this is overly tight in the face of "git add --intent-to-add": $ git add --intent-to-add file $ : oops, I don't actually want to stage that yet $ git rm --cached file error: 'empty' has staged content different from both the file and the HEAD (use -f to force removal) $ git rm -f --cached file Unfortunately, there is currently no way to distinguish between an empty file that has been added and an "intent to add" file. The ideal behavior would be to disallow the former while allowing the latter. This patch loosens the safety valve to allow the deletion only if we are deleting the cached entry and the cached content is empty. This covers the intent-to-add situation, and assumes there is little harm in not protecting users who have legitimately added an empty file. In many cases, the file will still be empty, in which case the safety valve does not trigger anyway (since the content remains untouched in the working tree). Otherwise, we do remove the fact that no content was staged, but given that the content is by definition empty, it is not terribly difficult for a user to recreate it. However, we still document the desired behavior in the form of two tests. One checks the correct removal of an intent-to-add file. The other checks that we still disallow removal of empty files, but is marked as expect_failure to indicate this compromise. If the intent-to-add feature is ever extended to differentiate between normal empty files and intent-to-add files, then the safety valve can be re-tightened.
