2018-01-16add--interactive: ignore submodule changes except HEADLibravatar Nguyễn Thái Ngọc Duy1-0/+48
For 'add -i' and 'add -p', the only action we can take on a dirty submodule entry is update the index with a new value from its HEAD. The content changes inside (from its own index, untracked files...) do not matter, at least until 'git add -i' learns about launching a new interactive add session inside a submodule. Ignore all other submodules changes except HEAD. This reduces the number of entries the user has to check through in 'git add -i', and the number of 'no' they have to answer to 'git add -p' when dirty submodules are present.

2018-01-10mingw: handle GITPERLLIB in t0021 in a Windows-compatible wayLibravatar Johannes Schindelin1-1/+16
Git's assumption that all path lists are colon-separated is not only wrong on Windows, it is not even an assumption that is compatible with POSIX. In the interest of time, let's not try to fix this properly but simply work around the obvious breakage on Windows, where the MSYS2 Bash used by Git for Windows to interpret the Git's Unix shell scripts will automagically convert path lists in the environment to semicolon-separated lists of Windows paths (with drive letter and the corresponding colon and all that jazz). In other words, we simply look whether there is a semicolon in GITPERLLIB and split by semicolons if found instead of colons. This is not fool-proof, of course, as the path list could consist of a single path. But that is not the case in Git for Windows' test suite, there are always two paths in GITPERLLIB.

2018-01-09merge-recursive: do not look at the index during recursive mergeLibravatar Junio C Hamano1-0/+50
When merging another branch into ours, if their tree is the same as the common ancestor's, we can declare that our tree represents the result of three-way merge. In such a case, the recursive merge backend incorrectly used to create a commit out of our index, even when the index has changes. A recent fix attempted to prevent this by adding a comparison between "our" tree and the index, but forgot that this check must be restricted only to the outermost merge. Inner merges performed by the recursive backend across merge bases are by definition made from scratch without having any local changes added to the index. The call to index_has_changes() during an inner merge is working on the index that has no relation to the merge being performed, preventing legitimate merges from getting carried out. Fix it by limiting the check to the outermost merge. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-01-08stash: don't delete untracked files that match pathspecLibravatar Thomas Gummerer1-0/+32
Currently when 'git stash push -- <pathspec>' is used, untracked files that match the pathspec will be deleted, even though they do not end up in a stash anywhere. This is because the original commit introducing the pathspec feature in git stash push (df6bba0937 ("stash: teach 'push' (and 'create_stash') to honor pathspec", 2017-02-28)) used the sequence of 'git reset <pathspec> && git ls-files --modified <pathspec> | git checkout-index && git clean <pathspec>'. The intention was to emulate what 'git reset --hard -- <pathspec>' would do. The call to 'git clean' was supposed to clean up the files that were unstaged by 'git reset'. This would work fine if the pathspec doesn't match any files that were untracked before 'git stash push -- <pathspec>'. However if <pathspec> matches a file that was untracked before invoking the 'stash' command, all untracked files matching the pathspec would inadvertently be deleted as well, even though they wouldn't end up in the stash, and are therefore lost. This behaviour was never what was intended, only blobs that also end up in the stash should be reset to their state in HEAD, previously untracked files should be left alone. To achieve this, first match what's in the index and what's in the working tree by adding all changes to the index, ask diff-index what changed between HEAD and the current index, and then apply that patch in reverse to get rid of the changes, which includes removal of added files and resurrection of removed files.

When using hard reset or forced checkout with the option to recurse into submodules, the submodules need to be reset, too.

It turns out that the test replacing a submodule with a file with the submodule containing an ignored file is incorrectly titled, because the test put the file in place, but never ignored that file. When having an untracked file Instead of an ignored file in the submodule, git should refuse to remove the submodule, but that is a bug in the implementation of recursing into submodules, such that the test just passed, removing the untracked file.

2018-01-04diffcore: add a pickaxe option to find a specific blobLibravatar Stefan Beller1-0/+68
Sometimes users are given a hash of an object and they want to identify it further (ex.: Use verify-pack to find the largest blobs, but what are these? or [1]) One might be tempted to extend git-describe to also work with blobs, such that `git describe <blob-id>` gives a description as '<commit-ish>:<path>'. This was implemented at [2]; as seen by the sheer number of responses (>110), it turns out this is tricky to get right. The hard part to get right is picking the correct 'commit-ish' as that could be the commit that (re-)introduced the blob or the blob that removed the blob; the blob could exist in different branches. Junio hinted at a different approach of solving this problem, which this patch implements. Teach the diff machinery another flag for restricting the information to what is shown. For example: $ ./git log --oneline --find-object=v2.0.0:Makefile b2feb64309 Revert the whole "ask curl-config" topic for now 47fbfded53 i18n: only extract comments marked with "TRANSLATORS:" we observe that the Makefile as shipped with 2.0 was appeared in v1.9.2-471-g47fbfded53 and in v2.0.0-rc1-5-gb2feb6430b. The reason why these commits both occur prior to v2.0.0 are evil merges that are not found using this new mechanism.

2018-01-03t0302 & t3900: add forgotten quotesLibravatar Johannes Schindelin2-5/+5
When cleaning up files in the $HOME directory, it really makes sense to quote the path, especially in Git's test suite, where the HOME directory is *guaranteed* to contain spaces in its name. It would appear that those two tests pass even without cleaning up the files, but really more by pure chance than by design (the cleanup seems not actually to be necessary). However, if anybody would have a left-over `trash/` directory in Git's `t/` directory, these tests would fail, because they would all of a sudden try to delete that directory, but without the `-r` (recursive) flag. That is how this issue was found. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

It is totally legitimate to clone Git's source code anywhere, including into, say, directories whose name (or the name of its absolute path) contains spaces. However, a couple of tests failed to anticipate this, for lack of quoting (or in one instance, for failure to expect more than one space in the absolute path of the TEST_DIRECTORY).

2018-01-03clone: do not clean up directories we didn't createLibravatar Jeff King1-5/+51
Once upon a time, git-clone would refuse to write into a directory that it did not itself create. The cleanup routines for a failed clone could therefore just remove the git and worktree dirs completely. In 55892d2398 (Allow cloning to an existing empty directory, 2009-01-11), we learned to write into an existing directory. Which means that doing: mkdir foo git clone will-fail foo ends up deleting foo. This isn't a huge catastrophe, since by definition foo must be empty. But it's somewhat confusing; we should leave the filesystem as we found it. Because we know that the only directory we'll write into is an empty one, we can handle this case by just passing the KEEP_TOPLEVEL flag to our recursive delete (if we could write into populated directories, we'd have to keep track of what we wrote and what we did not, which would be much harder). Note that we need to handle the work-tree and git-dir separately, though, as only one might exist (and the new tests in t5600 cover all cases).
