2017-01-08mv: remove use of deprecated 'get_pathspec()'Libravatar Brandon Williams1-19/+31
Convert the 'internal_copy_pathspec()' function to 'prefix_path()' instead of using the deprecated 'get_pathspec()' interface. Also, rename 'internal_copy_pathspec()' to 'internal_prefix_pathspec()' to be more descriptive of what the funciton is actually doing. In addition to this, fix a memory leak caused by only duplicating some of the pathspec elements. Instead always duplicate all of the the pathspec elements as an intermediate step (with modificationed based on the passed in flags). This way the intermediate strings can then be freed after getting the result from 'prefix_path()'.

2016-12-07hold_locked_index(): align error handling with hold_lockfile_for_update()Libravatar Junio C Hamano1-1/+1
Callers of the hold_locked_index() function pass 0 when they want to prepare to write a new version of the index file without wishing to die or emit an error message when the request fails (e.g. somebody else already held the lock), and pass 1 when they want the call to die upon failure. This option is called LOCK_DIE_ON_ERROR by the underlying lockfile API, and the hold_locked_index() function translates the paramter to LOCK_DIE_ON_ERROR when calling the hold_lock_file_for_update(). Replace these hardcoded '1' with LOCK_DIE_ON_ERROR and stop translating. Callers other than the ones that are replaced with this change pass '0' to the function; no behaviour change is intended with this patch. Signed-off-by: Junio C Hamano <gitster@pobox.com> --- Among the callers of hold_locked_index() that passes 0: - diff.c::refresh_index_quietly() at the end of "git diff" is an opportunistic update; it leaks the lockfile structure but it is just before the program exits and nobody should care. - builtin/describe.c::cmd_describe(), builtin/commit.c::cmd_status(), sequencer.c::read_and_refresh_cache() are all opportunistic updates and they are OK. - builtin/update-index.c::cmd_update_index() takes a lock upfront but we may end up not needing to update the index (i.e. the entries may be fully up-to-date), in which case we do not need to issue an error upon failure to acquire the lock. We do diagnose and die if we indeed need to update, so it is OK. - wt-status.c::require_clean_work_tree() IS BUGGY. It asks silence, does not check the returned value. Compare with callsites like cmd_describe() and cmd_status() to notice that it is wrong to call update_index_if_able() unconditionally.

2016-08-08git mv: do not keep slash in `git mv dir non-existing-dir/`Libravatar Johannes Schindelin1-4/+7
When calling `rename("dir", "non-existing-dir/")` on Linux, it silently succeeds, stripping the trailing slash of the second argument. This is all good and dandy but this behavior disagrees with the specs at http://pubs.opengroup.org/onlinepubs/9699919799/functions/rename.html that state clearly regarding the 2nd parameter (called `new`): If the `new` argument does not resolve to an existing directory entry for a file of type directory and the `new` argument contains at least one non- <slash> character and ends with one or more trailing <slash> characters after all symbolic links have been processed, `rename()` shall fail. Of course, we would like `git mv dir non-existing-dir/` to succeed (and rename the directory "dir" to "non-existing-dir"). Let's be extra careful to remove the trailing slash in that case. This lets t7001-mv.sh pass in Bash on Windows. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-04-19mv: allow moving nested submodulesLibravatar Stefan Beller1-9/+12
When directories are moved using `git mv` all files in the directory have been just moved, but no further action was taken on them. This was done by assigning the mode = WORKING_DIRECTORY to the files inside a moved directory. submodules however need to update their link to the git directory as well as updates to the .gitmodules file. By removing the condition of `mode != INDEX` (the remaining modes are BOTH and WORKING_DIRECTORY) for the required submodule actions, we perform these for submodules in a moved directory.

When commit a88c915 (mv: move submodules using a gitfile, 2013-07-30) added the submodule_gitfile array, it was not added to the block that enlarges the arrays when we are moving a directory so that we do not have to worry about it being a directory when we perform the actual move. After this, the loop continues over the enlarged set of sources. Since we assume that submodule_gitfile has size argc, if any of the items in the source directory are submodules we are guaranteed to write beyond the end of submodule_gitfile. Fix this by realloc'ing submodule_gitfile at the same time as the other arrays.

2014-02-18builtin/mv: don't use memory after freeLibravatar John Keeping1-1/+2
If 'src' already ends with a slash, then add_slash() will just return it, meaning that 'free(src_with_slash)' is actually 'free(src)'. Since we use 'src' later, this will result in use-after-free. In fact, this cannot happen because 'src' comes from internal_copy_pathspec() without the KEEP_TRAILING_SLASH flag, so any trailing '/' will have been stripped; but static analysis tools are not clever enough to realise this and so warn that 'src' could be used after having been free'd. Fix this by checking that 'src_w_slash' is indeed newly allocated memory. Signed-off-by: John Keeping <john@keeping.me.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The previous commit c57f628 (mv: let 'git mv file no-such-dir/' error out) relies on that rename("file", "no-such-dir/") fails if the directory does not exist (note the trailing slash). This does not work as expected on Windows: This rename() call does not fail, but renames "file" to "no-such-dir" (not to "no-such-dir/file"). Insert an explicit check for this case to force an error.

2013-10-13mv: Fix spurious warning when moving a file in presence of submodulesLibravatar Jens Lehmann1-4/+9
In commit 0656781fa "git mv" learned to update the submodule path in the .gitmodules file when moving a submodule in the work tree. But since that commit update_path_in_gitmodules() gets called no matter if we moved a submodule or a regular file, which is wrong and leads to a bogus warning when moving a regular file in a repo containing a .gitmodules file: warning: Could not find section in .gitmodules where path=<filename> Fix that by only calling update_path_in_gitmodules() when moving a submodule. To achieve that, we introduce the special SUBMODULE_WITH_GITDIR define to distinguish the cases where we also have to connect work tree and git directory from those where we only need to update the .gitmodules setting. A test for submodules using a .git directory together with a .gitmodules file has been added to t7001. Even though newer git versions will always use a gitfile when cloning submodules, repositories cloned with older git versions will still use this layout.

2013-08-06mv: update the path entry in .gitmodules for moved submodulesLibravatar Jens Lehmann1-1/+9
Currently using "git mv" on a submodule moves the submodule's work tree in that of the superproject. But the submodule's path setting in .gitmodules is left untouched, which is now inconsistent with the work tree and makes git commands that rely on the proper path -> name mapping (like status and diff) behave strangely. Let "git mv" help here by not only moving the submodule's work tree but also updating the "submodule.<submodule name>.path" setting from the .gitmodules file and stage both. This doesn't happen 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 updated the path setting by hand before issuing the "git mv" command (in which case the warning reminds him that mv would have done that for him). Only when .gitmodules is found and contains merge conflicts the mv command will fail and tell the user to resolve the conflict before trying again.

2013-07-30mv: move submodules using a gitfileLibravatar Jens Lehmann1-4/+15
When moving a submodule which uses a gitfile to point to the git directory stored in .git/modules/<name> of the superproject two changes must be made to make the submodule work: the .git file and the core.worktree setting must be adjusted to point from work tree to git directory and back. Achieve that by remembering which submodule uses a gitfile by storing the result of read_gitfile() of each submodule. If that is not NULL the new function connect_work_tree_and_git_dir() is called after renaming the submodule's work tree which updates the two settings to the new values. Extend the man page to inform the user about that feature (and while at it change the description to not talk about a script anymore, as mv is a builtin for quite some time now).

Currently the attempt to use "git mv" on a submodule errors out with: fatal: source directory is empty, source=<src>, destination=<dest> The reason is that mv searches for the submodule with a trailing slash in the index, which it doesn't find (because it is stored without a trailing slash). As it doesn't find any index entries inside the submodule it claims the directory would be empty even though it isn't. Fix that by searching for the name without a trailing slash and continue if it is a submodule. Then rename() will move the submodule work tree just like it moves a file.

This is less informative, but still sufficient in the simple rename case, as there is only one rename happening. But when moving files from one directory to another, it becomes useless: $ mkdir three $ touch one two three/one $ git add . $ git mv one two three fatal: destination exists, source=one, destination=three/one $ git mv -f one two three warning: destination exists; will overwrite!

If you try to "git mv" multiple files onto another non-directory file, you confusingly get the "usage" message: $ touch one two three $ git add . $ git mv one two three usage: git mv [options] <source>... <destination> [...] From the user's perspective, that makes no sense. They just gave parameters that exactly match that usage! This behavior dates back to the original C version of "git mv", which had a usage message like: usage: git mv (<source> <destination> | <source>... <destination>) This was slightly less confusing, because it at least mentions that there are two ways to invoke (but it still isn't clear why what the user provided doesn't work). Instead, let's show an error message like: $ git mv one two three fatal: destination 'three' is not a directory We could leave the usage message in place, too, but it doesn't actually help here. It contains no hints that there are two forms, nor that multi-file form requires that the endpoint be a directory. So it just becomes useless noise that distracts from the real error.
