2013-01-21Merge branch 'zk/clean-report-failure'Libravatar Junio C Hamano1-29/+125
"git clean" states what it is going to remove and then goes on to remove it, but sometimes it only discovers things that cannot be removed after recursing into a directory, which makes the output confusing and even wrong. * zk/clean-report-failure: git-clean: Display more accurate delete messages

2013-01-14git-clean: Display more accurate delete messagesLibravatar Zoltan Klinger1-29/+125
(1) Only print out the names of the files and directories that got actually deleted. Also do not mention that we are not removing directories when the user did not ask us to do so with '-d'. (2) Show ignore message for skipped untracked git repositories. Consider the following repo layout: test.git/ |-- tracked_dir/ | |-- some_tracked_file | |-- some_untracked_file |-- tracked_file |-- untracked_file |-- untracked_foo/ | |-- bar/ | | |-- bar.txt | |-- emptydir/ | |-- frotz.git/ | |-- frotz.tx |-- untracked_some.git/ |-- some.txt Suppose the user issues 'git clean -fd' from the test.git directory. When -d option is used and untracked directory 'foo' contains a subdirectory 'frotz.git' that is managed by a different git repository therefore it will not be removed. $ git clean -fd Removing tracked_dir/some_untracked_file Removing untracked_file Removing untracked_foo/ Removing untracked_some.git/ The message displayed to the user is slightly misleading. The foo/ directory has not been removed because of foo/frotz.git still exists. On the other hand the subdirectories 'bar' and 'emptydir' have been deleted but they're not mentioned anywhere. Also, untracked_some.git has not been removed either. This behaviour is the result of the way the deletion of untracked directories are reported. In the current implementation they are deleted recursively but only the name of the top most directory is printed out. The calling function does not know about any subdirectories that could not be removed during the recursion. Improve the way the deleted directories are reported back to the user: (1) Create a recursive delete function 'remove_dirs' in builtin/clean.c to run in both dry_run and delete modes with the delete logic as follows: (a) Check if the current directory to be deleted is an untracked git repository. If it is and --force --force option is not set do not touch this directory, print ignore message, set dir_gone flag to false for the caller and return. (b) Otherwise for each item in current directory: (i) If current directory cannot be accessed, print warning, set dir_gone flag to false and return. (ii) If the item is a subdirectory recurse into it, check for the returned value of the dir_gone flag. If the subdirectory is gone, add the name of the deleted directory to a list of successfully removed items 'dels'. Else set the dir_gone flag as the current directory cannot be removed because we have at least one subdirectory hanging around. (iii) If it is a file try to remove it. If success add the file name to the 'dels' list, else print error and set dir_gone flag to false. (c) After we finished deleting all items in the current directory and the dir_gone flag is still true, remove the directory itself. If failed set the dir_gone flag to false. (d) If the current directory cannot be deleted because the dir_gone flag has been set to false, print out all the successfully deleted items for this directory from the 'dels' list. (e) We're done with the current directory, return. (2) Modify the cmd_clean() function to: (a) call the recursive delete function 'remove_dirs()' for each topmost directory it wants to remove (b) check for the returned value of dir_gone flag. If it's true print the name of the directory as being removed. Consider the output of the improved version: $ git clean -fd Removing tracked_dir/some_untracked_file Removing untracked_file Skipping repository untracked_foo/frotz.git Removing untracked_foo/bar Removing untracked_foo/emptydir Skipping repository untracked_some.git/ Now it displays only the file and directory names that got actually deleted and shows the name of the untracked git repositories it ignored.

2013-01-10clone: forbid --bare --separate-git-dir <dir>Libravatar Nguyễn Thái Ngọc Duy1-0/+2
The --separate-git-dir option was introduced to make it simple to put the git directory somewhere outside the worktree, for example when cloning a repository for use as a submodule. It was not intended for use when creating a bare repository. In that case there is no worktree and it is more natural to directly clone the repository and create a .git file as separate steps: git clone --bare /path/to/repo.git bar.git printf 'gitdir: bar.git\n' >foo.git Forbid the combination, making the command easier to explain.

2013-01-05clone: support atomic operation with --separate-git-dirLibravatar Jens Lehmann1-1/+3
Since b57fb80a7d (init, clone: support --separate-git-dir for .git file) git clone supports the --separate-git-dir option to create the git dir outside the work tree. But when that option is used, the git dir won't be deleted in case the clone fails like it would be without this option. This makes clone lose its atomicity as in case of a failure a partly set up git dir is left behind. A real world example where this leads to problems is when "git submodule update" fails to clone a submodule and later calls to "git submodule update" stumble over the partially set up git dir and try to revive the submodule from there, which then fails with a not very user friendly error message. Fix that by updating the junk_git_dir variable (used to remember if and what git dir should be removed in case of failure) to the new value given with the --seperate-git-dir option. Also add a test for this to t5600 (and while at it fix the former last test to not cd into a directory to test for its existence but use "test -d" instead).

When it added a call to run the prepare-commit-msg hook, however, it forgot to check the exit code from the hook like "git commit" does, and ended up replacing one inconsistency with another. When prepare-commit-msg hook that is run from "git merge" exits with a non-zero status, abort the commit.

2012-12-28merge --no-edit: do not credit people involved in the side branchLibravatar Junio C Hamano2-7/+15
The credit lines "By" and "Via" to credit authors and committers for their contributions on the side branch are meant as a hint to the integrator to decide whom to mention in the log message text. After the integrator saves the message in the editor, they are meant to go away and that is why they are commented out. When a merge is recorded without editing the generated message, however, its contents do not go through the normal stripspace() and these lines are left in the merge.

2012-12-26merge-tree: fix d/f conflictsLibravatar Junio C Hamano1-32/+40
The previous commit documented two known breakages revolving around a case where one side flips a tree into a blob (or vice versa), where the original code simply gets confused and feeds a mixture of trees and blobs into either the recursive merge-tree (and recursing into the blob will fail) or three-way merge (and merging tree contents together with blobs will fail). Fix it by feeding trees (and only trees) into the recursive merge-tree machinery and blobs (and only blobs) into the three-way content level merge machinery separately; when this happens, the entire merge has to be marked as conflicting at the structure level.

2012-12-22format-patch: add --reroll-count=$N optionLibravatar Junio C Hamano1-0/+11
The --reroll-count=$N option, when given a positive integer: - Adds " v$N" to the subject prefix specified. As the default subject prefix string is "PATCH", --reroll-count=2 makes it "PATCH v2". - Prefixes "v$N-" to the names used for output files. The cover letter, whose name is usually 0000-cover-letter.patch, becomes v2-0000-cover-letter.patch when given --reroll-count=2. This allows users to use the same --output-directory for multiple iterations of the same series, without letting the output for a newer round overwrite output files from the earlier rounds. The user can incorporate materials from earlier rounds to update the newly minted iteration, and use "send-email v2-*.patch" to send out the patches belonging to the second iteration easily.

2012-12-03fast-export: make sure updated refs get updatedLibravatar Felipe Contreras1-3/+7
When an object has already been exported (and thus is in the marks) it's flagged as SHOWN, so it will not be exported again, even if in a later time it's exported through a different ref. We don't need the object to be exported again, but we want the ref updated, which doesn't happen. Since we can't know if a ref was exported or not, let's just assume that if the commit was marked (flags & SHOWN), the user still wants the ref updated. IOW: If it's specified in the command line, it will get updated, regardless of whether or not the object was marked. So: % git branch test master % git fast-export $mark_flags master % git fast-export $mark_flags test Would export 'test' properly. Additionally, this fixes issues with remote helpers; now they can push refs whose objects have already been exported, and a few other issues as well. Update the tests accordingly.

2012-12-03fast-export: don't handle uninteresting refsLibravatar Felipe Contreras1-4/+7
They have been marked as UNINTERESTING for a reason, lets respect that. Currently the first ref is handled properly, but not the rest. Assuming that all the refs point at the same commit in the following example: % git fast-export master ^uninteresting ^foo ^bar reset refs/heads/bar from :0 reset refs/heads/foo from :0 reset refs/heads/uninteresting from :0 % git fast-export ^uninteresting ^foo ^bar master reset refs/heads/master from :0 reset refs/heads/bar from :0 reset refs/heads/foo from :0 Clearly this is wrong; the negative refs should be ignored. After this patch: % git fast-export ^uninteresting ^foo ^bar master # nothing % git fast-export master ^uninteresting ^foo ^bar # nothing And even more, it would only happen if the ref is pointing to exactly the same commit, but not otherwise: % git fast-export ^next next reset refs/heads/next from :0 % git fast-export ^next next^{commit} # nothing % git fast-export ^next next~0 # nothing % git fast-export ^next next~1 # nothing % git fast-export ^next next~2 # nothing The reason this happens is that before traversing the commits, fast-export checks if any of the refs point to the same object, and any duplicated ref gets added to a list in order to issue 'reset' commands after the traversing. Unfortunately, it's not even checking if the commit is flagged as UNINTERESTING. The fix of course, is to check it. However, in order to do it properly we need to get the UNINTERESTING flag from the command line, not from the commit object, because "^foo bar" will mark the commit 'bar' uninteresting if foo and bar points at the same commit. rev_cmdline_info, which was introduced exactly to handle this situation, contains all the information we need for get_tags_and_duplicates(), plus the ref flag. This way the rest of the positive refs will remain untouched; it's only the negative ones that change in behavior.
