2015-03-20Merge branch 'mg/detached-head-report'Libravatar Junio C Hamano1-3/+10
"git branch" on a detached HEAD always said "(detached from xyz)", even when "git status" would report "detached at xyz".

2015-03-06branch: name detached HEAD analogous to statusLibravatar Michael J Gruber1-3/+10
"git status" carefully names a detached HEAD "at" resp. "from" a rev or ref depending on whether the detached HEAD has moved since. "git branch" always uses "from", which can be confusing, because a status-aware user would interpret this as moved detached HEAD. Make "git branch" use the same logic and wording.

2015-02-17ref_transaction_verify(): new function to check a reference's valueLibravatar Michael Haggerty1-5/+2
If NULL is passed to ref_transaction_update()'s new_sha1 parameter, then just verify old_sha1 (under lock) without trying to change the new value of the reference. Use this functionality to add a new function ref_transaction_verify(), which checks the current value of the reference under lock but doesn't change it. Use ref_transaction_verify() in the implementation of "git update-ref --stdin"'s "verify" command to avoid the awkward need to "update" the reference to its existing value.

2015-02-10apply: do not touch a file beyond a symbolic linkLibravatar Junio C Hamano1-0/+112
Because Git tracks symbolic links as symbolic links, a path that has a symbolic link in its leading part (e.g. path/to/dir/file, where path/to/dir is a symbolic link to somewhere else, be it inside or outside the working tree) can never appear in a patch that validly applies, unless the same patch first removes the symbolic link to allow a directory to be created there. Detect and reject such a patch. Things to note: - Unfortunately, we cannot reuse the has_symlink_leading_path() from dir.c, as that is only about the working tree, but "git apply" can be told to apply the patch only to the index or to both the index and to the working tree. - We cannot directly use has_symlink_leading_path() even when we are applying only to the working tree, as an early patch of a valid input may remove a symbolic link path/to/dir and then a later patch of the input may create a path path/to/dir/file, but "git apply" first checks the input without touching either the index or the working tree. The leading symbolic link check must be done on the interim result we compute in-core (i.e. after the first patch, there is no path/to/dir symbolic link and it is perfectly valid to create path/to/dir/file). Similarly, when an input creates a symbolic link path/to/dir and then creates a file path/to/dir/file, we need to flag it as an error without actually creating path/to/dir symbolic link in the filesystem. Instead, for any patch in the input that leaves a path (i.e. a non deletion) in the result, we check all leading paths against the resulting tree that the patch would create by inspecting all the patches in the input and then the target of patch application (either the index or the working tree). This way, we catch a mischief or a mistake to add a symbolic link path/to/dir and a file path/to/dir/file at the same time, while allowing a valid patch that removes a symbolic link path/to/dir and then adds a file path/to/dir/file.

2015-02-10apply: do not read from beyond a symbolic linkLibravatar Junio C Hamano1-0/+2
We should reject a patch, whether it renames/copies dir/file to elsewhere with or without modificiation, or updates dir/file in place, if "dir/" part is actually a symbolic link to elsewhere, by making sure that the code to read the preimage does not read from a path that is beyond a symbolic link.

2015-02-10apply: do not read from the filesystem under --indexLibravatar Junio C Hamano1-1/+1
We currently read the preimage to apply a patch from the index only when the --cached option is given. Do so also when the command is running under the --index option. With --index, the index entry and the working tree file for a path that is involved in a patch must be identical, so this should not affect the result, but by reading from the index, we will get the protection to avoid reading an unintended path beyond a symbolic link automatically. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-02-10apply: reject input that touches outside the working areaLibravatar Junio C Hamano1-0/+26
By default, a patch that affects outside the working area (either a Git controlled working tree, or the current working directory when "git apply" is used as a replacement of GNU patch) is rejected as a mistake (or a mischief). Git itself does not create such a patch, unless the user bends over backwards and specifies a non-standard prefix to "git diff" and friends. When `git apply` is used as a "better GNU patch", the user can pass the `--unsafe-paths` option to override this safety check. This option has no effect when `--index` or `--cached` is in use. The new test was stolen from Jeff King with slight enhancements. Note that a few new tests for touching outside the working area by following a symbolic link are still expected to fail at this step, but will be fixed in later steps.
