| | | | | | | | | | | | Not only does this save us having to implement a custom callback, but it handles "--no-reference" in the usual way (to clear the list). The generic callback does copy the string, which we don't technically need, but that should not hurt anything.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The expected call sequence is for the caller to use match_pathspec() repeatedly on a set of pathspecs, accumulating the "hits" in a separate array, and then call this function to diagnose a pathspec that never matched anything, as that can indicate a typo from the command line, e.g. "git commit Maekfile". Many builtin commands use this function from builtin/ls-files.c, which is not a very healthy arrangement. ls-files might have been the first command to feel the need for such a helper, but the need is shared by everybody who uses the "match and then report" pattern. Move it to dir.c where match_pathspec() is defined. Signed-off-by: Junio C Hamano <gitster@pobox.com>

We do this by installing an atexit handler, so that we don't have to manually trigger cleanup. However, since we install this after touching the filesystem, any errors between our initial mkdir() and our atexit() call will result in us leaving a crufty directory around. We can fix this by moving our atexit() call earlier. It's OK to do it before the junk_work_tree variable is set, because remove_junk makes sure the variable is initialized. This means we "activate" the handler by assigning to the junk_work_tree variable, which we now bump down to just after we call mkdir(). We probably do not want to do it before, because a plausible reason for mkdir() to fail is EEXIST (i.e., we are racing with another "git init"), and we would not want to remove their work. OTOH, this is probably not that big a deal; we will allow cloning into an empty directory (and skip the mkdir), which is already racy (i.e., one clone may see the other's empty dir and start writing into it). Still, it does not hurt to err on the side of caution here. Note that writing into junk_work_tree and junk_git_dir after installing the handler is also technically racy, as we call our handler on an async signal. Depending on the platform, we could see a sheared write to the variables. Traditionally we have not worried about this, and indeed we already do this later in the function. If we want to address that, it can come as a separate topic. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

It's better for us to abort the operation on the broken object than it is to start deleting objects with an incomplete view of the reachability namespace. Note that for missing objects, aborting is the best we can do. For a badly-named ref, we technically could use its sha1 as a reachability tip. However, the iteration code just feeds us a null sha1, so there would be a reasonable amount of code involved to pass down our wishes. It's not really worth trying to do better, because this is a case that should happen extremely rarely, and the message we provide: fatal: unable to parse object: refs/heads/bogus:name is probably enough to point the user in the right direction.

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.

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.

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.

When they are found to match, the common context lines in the preimage is replaced with the fixed copy, because these lines will then be copied to the corresponding place in the postimage by a later call to update_pre_post_images(). Lines that are added in the postimage, under --whitespace=fix, have their whitespace errors already fixed when apply_one_fragment() prepares the preimage and the postimage, so in the end, application of the patch can be done by replacing the block of text in the file being patched that matched the preimage with what is in the postimage that was updated by update_pre_post_images(). In the earlier days, fixing whitespace errors always resulted in reduction of size, either collapsing runs of spaces in the indent to a tab or removing the trailing whitespaces. These days, however, some whitespace error fix results in extending the size. 250b3c6c (apply --whitespace=fix: avoid running over the postimage buffer, 2013-03-22) tried to compute the final postimage size but its math was flawed. It counted the size of the block of text in the original being patched after fixing the whitespace errors on its lines that correspond to the preimage. That number does not have much to do with how big the final postimage would be. Instead count (1) the added lines in the postimage, whose size is the same as in the final patch result because their whitespace errors have already been corrected, and (2) the fixed size of the lines that are common.

An update to accomodate fixes that lengthens the result by e.g. expanding leading tabs into spaces were made long time ago but the logic miscounted the necessary space after such whitespace fixes, leading to either under-allocation or over-usage of already allocated space. Illustrate this with a runtime sanity-check to protect us from future breakage. The test was stolen from Kyle McKay who helped to identify the problem. Helped-by: "Kyle J.

This is confusing for users who try to specify a valid complete author name. Rename the error message to make it clearer that the failure has two reasons in this case. (This codepath is touched only when we know already that the argument cannot be a completely wellformed author ident.)

This array is later rebuilt when running prepare_revision_walk() which potentially transforms the pointer target into a bogus string. Fix this by maintaining a copy of the original string.
