* prefer git_pathdup to git_path in some possibly-dangerous casesJeff King2015-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | Because git_path uses a static buffer that is shared with calls to git_path, mkpath, etc, it can be dangerous to assign the result to a variable or pass it to a non-trivial function. The value may change unexpectedly due to other calls. None of the cases changed here has a known bug, but they're worth converting away from git_path because: 1. It's easy to use git_pathdup in these cases. 2. They use constructs (like assignment) that make it hard to tell whether they're safe or not. The extra malloc overhead should be trivial, as an allocation should be an order of magnitude cheaper than a system call (which we are clearly about to make, since we are constructing a filename). The real cost is that we must remember to free the result. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * path.c: make get_pathname() call sites return const char *Nguyễn Thái Ngọc Duy2014-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before the previous commit, get_pathname returns an array of PATH_MAX length. Even if git_path() and similar functions does not use the whole array, git_path() caller can, in theory. After the commit, get_pathname() may return a buffer that has just enough room for the returned string and git_path() caller should never write beyond that. Make git_path(), mkpath() and git_path_submodule() return a const buffer to make sure callers do not write in it at all. This could have been part of the previous commit, but the "const" conversion is too much distraction from the core changes in path.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The callers of get_merge_bases() can choose to leave object flags used during the merge-base traversal by passing cleanup=0 as a parameter, but in practice a very few callers can afford to do so (namely, "git merge-base"), as they need to compute merge base in preparation for other processing of their own and they need to see the object without contaminate flags. Change the function signature of get_merge_bases_many() and get_merge_bases() to drop the cleanup parameter, so that the majority of the callers do not have to say ", 1" at the end. Give a new get_merge_bases_many_dirty() API to support only a few callers that know they do not need to spend cycles cleaning up the object flags. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | refs.c: change resolve_ref_unsafe reading argument to be a flags fieldRonnie Sahlberg2014-10-15

Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited.

* commit: record buffer length in cacheJeff King2014-06-13
| | | | | | | | | | | | | | | | | | | | | | | | Most callsites which use the commit buffer try to use the cached version attached to the commit, rather than re-reading from disk. Unfortunately, that interface provides only a pointer to the NUL-terminated buffer, with no indication of the original length. For the most part, this doesn't matter. People do not put NULs in their commit messages, and the log code is happy to treat it all as a NUL-terminated string. However, some code paths do care. For example, when checking signatures, we want to be very careful that we verify all the bytes to avoid malicious trickery. This patch just adds an optional "size" out-pointer to get_commit_buffer and friends. The existing callers all pass NULL (there did not seem to be any obvious sites where we could avoid an immediate strlen() call, though perhaps with some further refactoring we could).

* replace dangerous uses of strbuf_attachJeff King2014-06-12
| | | | | | | | | | | | | | | | | | | | | | | | It is not a good idea to strbuf_attach an arbitrary pointer just because a function you are calling wants a strbuf. Attaching implies a transfer of memory ownership; if anyone were to modify or release the resulting strbuf, we would free() the pointer, leading to possible problems: 1. Other users of the original pointer might access freed memory. 2. The pointer might not be the start of a malloc'd area, so calling free() on it in the first place would be wrong. In the two cases modified here, we are fortunate that nobody touches the strbuf once it is attached, but it is an accident waiting to happen. Since the previous commit, commit_tree and friends take a pointer/buf pair, so we can just do away with the strbufs entirely.

* commit_tree: take a pointer/len pair rather than a const strbufJeff King2014-06-12
| | | | | | | | | | | | | | | | | | While strbufs are pretty common throughout our code, it is more flexible for functions to take a pointer/len pair than a strbuf. It's easy to turn a strbuf into such a pair (by dereferencing its members), but less easy to go the other way (you can strbuf_attach, but that has implications about memory ownership). This patch teaches commit_tree (and its associated callers and sub-functions) to take such a pair for the commit message rather than a strbuf. This makes passing the buffer around slightly more verbose, but means we can get rid of some dangerous strbuf_attach calls in the next patch.

* | notes-merge: Don't remove .git/NOTES_MERGE_WORKTREE; it may be the user's cwdJohan Herland2012-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a manual notes merge is committed or aborted, we need to remove the temporary worktree at .git/NOTES_MERGE_WORKTREE. However, removing the entire directory is not good if the user ran the 'git notes merge --commit/--abort' from within that directory. On Windows, the directory removal would simply fail, while on POSIX systems, users would suddenly find themselves in an invalid current directory. Therefore, instead of deleting the entire directory, we delete everything _within_ the directory, and leave the (empty) directory in place. This would cause a subsequent notes merge to abort, complaining about a previous - unfinished - notes merge (due to the presence of .git/NOTES_MERGE_WORKTREE), so we also need to adjust this check to only trigger when .git/NOTES_MERGE_WORKTREE is non-empty. Finally, adjust the t3310 manual notes merge testcases to correctly handle the existence of an empty .git/NOTES_MERGE_WORKTREE directory.

* | notes-merge: use opendir/readdir instead of using read_directory()Johan Herland2012-03-15
|/ | | | | | | | | | | | | | | | | | | | notes_merge_commit() only needs to list all entries (non-recursively) under a directory, which can be easily accomplished with opendir/readdir and would be more lightweight than read_directory(). read_directory() is designed to list paths inside a working directory. Using it outside of its scope may lead to undesired effects. Apparently, one of the undesired effects of read_directory() is that it doesn't deal with being given absolute paths. This creates problems for notes_merge_commit() when git_path() returns an absolute path, which happens when the current working directory is in a subdirectory of the .git directory.

If we place it at the end of the log message, we would need to teach "git log" and friends to strip the signature block with an option. - Teaching new versions of "git log" and "gitk" to optionally verify and show signatures is cleaner if we structurally know where the signature block is (instead of scanning in the commit log message). - The signature needs to be stripped upon various commit rewriting operations, e.g. rebase, filter-branch, etc. They all already ignore unknown headers, but if we place signature in the log message, all of these tools (and third-party tools) also need to learn how a signature block would look like. - When we added the optional encoding header, all the tools (both in tree and third-party) that acts on the raw commit object should have been fixed to ignore headers they do not understand, so it is not like that new header would be more likely to break than extra text in the commit.

* correct type of EMPTY_TREE_SHA1_BINJonathan Nieder2011-02-14
| | | | | | | | | | | | | | | | | Functions such as hashcmp that expect a binary SHA-1 value take parameters of type "unsigned char *" to avoid accepting a textual SHA-1 passed by mistake. Unfortunately, this means passing the string literal EMPTY_TREE_SHA1_BIN requires an ugly cast. Tweak the definition of EMPTY_TREE_SHA1_BIN to produce a value of more convenient type. In the future the definition might change to extern const unsigned char empty_tree_sha1_bin[20]; #define EMPTY_TREE_SHA1_BIN empty_tree_sha1_bin Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* git notes merge: Add another auto-resolving strategy: "cat_sort_uniq"Johan Herland2010-11-17
| | | | | | | | | | | | | | | | | | This new strategy is similar to "concatenate", but in addition to concatenating the two note candidates, this strategy sorts the resulting lines, and removes duplicate lines from the result. This is equivalent to applying the "cat | sort | uniq" shell pipeline to the two note candidates. This strategy is useful if the notes follow a line-based format where one wants to avoid duplicate lines in the merge result. Note that if either of the note candidates contain duplicate lines _prior_ to the merge, these will also be removed by this merge strategy. The patch also contains tests and documentation for the new strategy. Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* git notes merge: Manual conflict resolution, part 2/2Johan Herland2010-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been resolved, we need to record a new notes commit on the appropriate notes ref with the resolved notes. This patch implements 'git notes merge --commit' which the user should run after resolving conflicts in the notes merge worktree. This command finalizes the notes merge by recombining the partial notes tree from part 1 with the now-resolved conflicts in the notes merge worktree in a merge commit, and updating the appropriate ref to this merge commit. In order to correctly finalize the merge, we need to keep track of three things: - The partial merge result from part 1, containing the auto-merged notes. This is now stored into a ref called .git/NOTES_MERGE_PARTIAL. - The unmerged notes. These are already stored in .git/NOTES_MERGE_WORKTREE, thanks to part 1. - The notes ref to be updated by the finalized merge result. This is now stored in a symref called .git/NOTES_MERGE_REF. In addition to "git notes merge --commit", which uses the above details to create the finalized notes merge commit, this patch also implements "git notes merge --reset", which aborts the ongoing notes merge by simply removing the files/directory described above. FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove the information described above (.git/NOTES_MERGE_*) after the notes merge have been successfully finalized. The patch also contains documentation and testcases for the two new options. This patch has been improved by the following contributions: - Ævar Arnfjörð Bjarmason: Fix nonsense sentence in --commit description - Sverre Rabbelier: Rename --reset to --abort Thanks-to: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Thanks-to: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* git notes merge: Manual conflict resolution, part 1/2Johan Herland2010-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Conflicts (that are to be resolved manually) are written into a special- purpose working tree, located at .git/NOTES_MERGE_WORKTREE. Within this directory, conflicting notes entries are stored (with conflict markers produced by ll_merge()) using the SHA1 of the annotated object. The .git/NOTES_MERGE_WORKTREE directory will only contain the _conflicting_ note entries. The non-conflicting note entries (aka. the partial merge result) are stored in 'local_tree', and the SHA1 of the resulting commit is written to 'result_sha1'. The return value from notes_merge() is -1. The user is told to edit the files within the .git/NOTES_MERGE_WORKTREE directory in order to resolve the conflicts. The patch also contains documentation and testcases for the correct setup of .git/NOTES_MERGE_WORKTREE. The next part will recombine the partial notes merge result with the resolved conflicts in .git/NOTES_MERGE_WORKTREE to produce the complete merge result.

* git notes merge: Add automatic conflict resolvers (ours, theirs, union)Johan Herland2010-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new -s/--strategy command-line option to 'git notes merge' allow the user to choose how notes merge conflicts should be resolved. There are four valid strategies to choose from: 1. "manual" (the default): This will let the user manually resolve conflicts. This option currently fails with an error message. It will be implemented properly in future patches. 2. "ours": This automatically chooses the local version of a conflict, and discards the remote version. 3. "theirs": This automatically chooses the remote version of a conflict, and discards the local version. 4. "union": This automatically resolves the conflict by appending the remote version to the local version. The strategies are implemented using the combine_notes_* functions from the notes.h API. The patch also includes testcases verifying the correct implementation of these strategies. This patch has been improved by the following contributions: - Jonathan Nieder: Future-proof by always checking add_note() return value - Stephen Boyd: Use test_commit - Stephen Boyd: Use correct option name Thanks-to: Jonathan Nieder <jrnieder@gmail.com> Thanks-to: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* git notes merge: Handle real, non-conflicting notes mergesJohan Herland2010-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This continuation of the 'git notes merge' implementation teaches notes-merge to properly do real merges between notes trees: Two diffs are performed, one from $base to $remote, and another from $base to $local. The paths in each diff are normalized to SHA1 object names. The two diffs are then consolidated into a single list of change pairs to be evaluated. Each change pair consist of: - The annotated object's SHA1 - The $base SHA1 (i.e. the common ancestor notes for this object) - The $local SHA1 (i.e. the current notes for this object) - The $remote SHA1 (i.e. the to-be-merged notes for this object) From the pair ($base -> $local, $base -> $remote), we can determine the merge result using regular 3-way rules. If conflicts are encountered in this process, we fail loudly and exit (conflict handling to be added in a future patch), If we can complete the merge without conflicts, the resulting notes tree is committed, and the current notes ref updated. The patch includes added testcases verifying that we can successfully do real conflict-less merges.
