2015-01-14standardize usage info string formatAlex Henrie
This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <alexhenrie24@gmail.com> Reviewed-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-03-11builtin/mv: fix out of bounds writeJohn Keeping
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 freeJohn Keeping
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>
2014-01-10mv: let 'git mv file no-such-dir/' error out on Windows, tooJohannes Sixt
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. This changes the error message from $ git mv file no-such-dir/ fatal: renaming 'file' failed: Not a directory to $ git mv file no-such-dir/ fatal: destination directory does not exist, source=file, destination=no-such-dir/ Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-12-04mv: let 'git mv file no-such-dir/' error outMatthieu Moy
Git used to trim the trailing slash, and make the command equivalent to 'git mv file no-such-dir', which created the file no-such-dir (while the trailing slash explicitly stated that it could only be a directory). This patch skips the trailing slash removal for the destination path. The path with its trailing slash is passed to rename(2), which errors out with the appropriate message: $ git mv file no-such-dir/ fatal: renaming 'file' failed: Not a directory Original-patch-by: Duy Nguyen <pclouds@gmail.com> Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-10-14mv: Fix spurious warning when moving a file in presence of submodulesJens Lehmann
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 submodulesJens Lehmann
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. Also extend the man page to inform the user about this new feature. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-07-30mv: move submodules using a gitfileJens Lehmann
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).

2013-07-30mv: move submodules together with their work treesJens Lehmann
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.

2013-07-15pathspec: add copy_pathspecNguyễn Thái Ngọc Duy
Because free_pathspec wants to free "items" pointer in the pathspec structure, a simple structure assignment is not enough if you want to copy an existing pathspec into another. Freeing the original will damage the copy unless a deep copy is made. Note that the strings in pathspec->items->match and the array pathspec->raw[] are still shared between the original and the copy.

2011-12-12mv: be quiet about overwritingJeff King
When a user asks us to force a mv and overwrite the destination, we print a warning. However, since a typical use would be: $ git mv one two fatal: destination exists, source=one, destination=two $ git mv -f one two warning: overwriting 'two' this warning is just noise. We already know we're overwriting; that's why we gave -f! This patch silences the warning unless "--verbose" is given.

2011-12-12mv: improve overwrite warningJeff King
When we try to "git mv" over an existing file, the error message is fairly informative: $ git mv one two fatal: destination exists, source=one, destination=two When the user forces the overwrite, we give a warning: $ git mv -f one two warning: destination exists; will overwrite! 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! The first message is helpful, but the second one gives us no clue about what was overwritten. Let's mention the name of the destination file: $ git mv -f one two three warning: overwriting 'three/one' Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-12-12mv: make non-directory destination error more clearJeff King
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.

Additionally, the call to malloc in compat/win32/syslog.c was not modified since the syslog() implemented there is a die handler and a call to the x-wrappers within a die handler could result in recursion should memory allocation fail.

NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion.
