* rm: only refresh entries that we may touchNguyễn Thái Ngọc Duy2010-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This gets rid of the whole tree cache refresh. Instead only path that we touch will get refreshed. We may still lstat() more than needed, but it'd be better playing safe. This potentially reduces a large number of lstat() on big trees. Take gentoo-x86 tree for example, which has roughly 80k files: Unmodified Git: $ time git rm --cached skel.ebuild rm 'skel.ebuild' real 0m1.441s user 0m0.821s sys 0m0.531s Modified Git: $ time ~/w/git/git rm --cached skel.ebuild rm 'skel.ebuild' real 0m0.941s user 0m0.828s sys 0m0.091s Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Convert existing die(..., strerror(errno)) to die_errno()Thomas Rast2009-06-27
| | | | | | | | | | | Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.

* parse-opts: prepare for OPT_FILENAMEStephen Boyd2009-05-25
| | | | | | | | | | To give OPT_FILENAME the prefix, we pass the prefix to parse_options() which passes the prefix to parse_options_start() which sets the prefix member of parse_opts_ctx accordingly.

* git add --intent-to-add: fix removal of cached emptinessJunio C Hamano2008-11-28
| | | | | | | | | | | | | | | | | | 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>

* rm: loosen safety valve for empty filesJeff King2008-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Simplify cache APIJunio C Hamano2007-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, add_file_to_index() invalidated the path in the cache-tree but remove_file_from_cache() did not, and the user of the latter needed to invalidate the entry himself. This led to a few bugs due to missed invalidate calls already. This patch makes the management of cache-tree less error prone by making more invalidate calls from lower level cache API functions. The rules are: - If you are going to write the index, you should either maintain cache_tree correctly. - If you cannot, alternatively you can remove the entire cache_tree by calling cache_tree_free() before you call write_cache(). - When you modify the index, cache_tree_invalidate_path() should be called with the path you are modifying, to discard the entry from the cache-tree structure. - The following cache API functions exported from read-cache.c (and the macro whose names have "cache" instead of "index") automatically call cache_tree_invalidate_path() for you: - remove_file_from_index(); - add_file_to_index(); - add_index_entry(); You can modify the index bypassing the above API functions (e.g. find an existing cache entry from the index and modify it in place). You need to call cache_tree_invalidate_path() yourself in such a case. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* More permissive "git-rm --cached" behavior without -f.Matthieu Moy2007-07-13
| | | | | | | | | | | | | | | | In the previous behavior, "git-rm --cached" (without -f) had the same restriction as "git-rm". This forced the user to use the -f flag in situations which weren't actually dangerous, like: $ git add foo # oops, I didn't want this $ git rm --cached foo # back to initial situation Previously, the index had to match the file *and* the HEAD. With --cached, the index must now match the file *or* the HEAD. The behavior without --cached is unchanged, but provides better error messages.

* _GIT_INDEX_OUTPUT: allow plumbing to output to an alternative index file.Junio C Hamano2007-04-03
| | | | | | | | | | | | | | | | | | | | | When defined, this allows plumbing commands that update the index (add, apply, checkout-index, merge-recursive, mv, read-tree, rm, update-index, and write-tree) to write their resulting index to an alternative index file while holding a lock to the original index file. With this, git-commit that jumps the index does not have to make an extra copy of the index file, and more importantly, it can do the update while holding the lock on the index. However, I think the interface to let an environment variable specify the output is a mistake, as shown in the documentation. If a curious user has the environment variable set to something other than the file GIT_INDEX_FILE points at, almost everything will break. This should instead be a command line parameter to tell these plumbing commands to write the result in the named file, to prevent stupid mistakes. Signed-off-by: Junio C Hamano <junkio@cox.net>

* git-rm: update to saner semanticsJunio C Hamano2006-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the "git rm" command with saner semantics suggested on the list earlier with: Message-ID: <Pine.LNX.4.64.0612020919400.3476@woody.osdl.org> Message-ID: <Pine.LNX.4.64.0612040737120.3476@woody.osdl.org> The command still validates that the given paths all talk about sensible paths to avoid mistakes (e.g. "git rm fiel" when file "fiel" does not exist would error out -- user meant to remove "file"), and it has further safety checks described next. The biggest difference is that the paths are removed from both index and from the working tree (if you have an exotic need to remove paths only from the index, you can use the --cached option). The command refuses to remove if the copy on the working tree does not match the index, or if the index and the HEAD does not match. You can defeat this check with -f option. This safety check has two exceptions: if the working tree file does not exist to begin with, that technically does not match the index but it is allowed. This is to allow this CVS style command sequence: rm <path> && git rm <path> Also if the index is unmerged at the <path>, you can use "git rm <path>" to declare that the result of the merge loses that path, and the above safety check does not trigger; requiring the file to match the index in this case forces the user to do "git update-index file && git rm file", which is just crazy. To recursively remove all contents from a directory, you need to pass -r option, not just the directory name as the <path>. Signed-off-by: Junio C Hamano <junkio@cox.net>

* Better error message when we are unable to lock the index fileJunio C Hamano2006-08-12
| | | | | | | | | | | | | | | | | Most of the callers except the one in refs.c use the function to update the index file. Among the index writers, everybody except write-tree dies if they cannot open it for writing. This gives the function an extra argument, to tell it to die when it cannot create a new file as the lockfile. The only caller that does not have to die is write-tree, because updating the index for the cache-tree part is optional and not being able to do so does not affect the correctness. I think we do not have to be so careful and make the failure into die() the same way as other callers, but that would be a different patch. Signed-off-by: Junio C Hamano <junkio@cox.net>

* Add builtin "git rm" commandLinus Torvalds2006-05-19
This changes semantics very subtly, because it adds a new atomicity guarantee. In particular, if you "git rm" several files, it will now do all or nothing. The old shell-script really looped over the removed files one by one, and would basically randomly fail in the middle if "-f" was used and one of the files didn't exist in the working directory. This C builtin one will not re-write the index after each remove, but instead remove all files at once. However, that means that if "-f" is used (to also force removal of the file from the working directory), and some files have already been removed from the workspace, it won't stop in the middle in some half-way state like the old one did. So what happens is that if the _first_ file fails to be removed with "-f", we abort the whole "git rm". But once we've started removing, we don't leave anything half done. If some of the other files don't exist, we'll just ignore errors of removal from the working tree. This is only an issue with "-f", of course. I think the new behaviour is strictly an improvement, but perhaps more importantly, it is _different_. As a special case, the semantics are identical for the single-file case (which is the only one our test-suite seems to test). The other question is what to do with leading directories. The old "git rm" script didn't do anything, which is somewhat inconsistent. This one will actually clean up directories that have become empty as a result of removing the last file, but maybe we want to have a flag to decide the behaviour?
