2018-01-30cache: clear whole hash buffer with oidclrLibravatar Patryk Obara1-1/+1
As long as GIT_SHA1_RAWSZ is equal to GIT_MAX_RAWSZ there's no problem, but when new hashing algorithm will be in place this memset will clear only 20-byte prefix of hash buffer. Alternatively, hashclr implementation could be adjusted, but this function is almost removed from codebase already. Separate implementation of oidclr prevents potential buffer overrun in case someone incorrectly used hashclr on object_id in future.

Make it safer to normalize the line endings in a repository. Files that had been commited with CRLF will be commited with LF.

The new "add --renormalize" does not add untracked files: $ echo "* text=auto" >.gitattributes $ git add --renormalize . $ git commit -m "Introduce end-of-line normalization" Note that "git add --renormalize <pathspec>" is the short form for "git add -u --renormalize <pathspec>".

2017-11-13Integrate hash algorithm support with repo setupLibravatar brian m. carlson1-0/+4
In future versions of Git, we plan to support an additional hash algorithm. Integrate the enumeration of hash algorithms with repository setup, and store a pointer to the enumerated data in struct repository. Of course, we currently only support SHA-1, so hard-code this value in read_repository_format. In the future, we'll enumerate this value from the configuration. Add a constant, the_hash_algo, which points to the hash_algo structure pointer in the repository global. Note that this is the hash which is used to serialize data to disk, not the hash which is used to display items to the user. The transition plan anticipates that these may be different. We can add an additional element in the future (say, ui_hash_algo) to provide for this case. Include repository.h in cache.h since we now need to have access to these struct and variable definitions.

2017-11-01fsmonitor: delay updating state until after split index is mergedLibravatar Alex Vandiver1-0/+1
If the fsmonitor extension is used in conjunction with the split index extension, the set of entries in the index when it is first loaded is only a subset of the real index. This leads to only the non-"base" index being marked as CE_FSMONITOR_VALID. Delay the expansion of the ewah bitmap until after tweak_split_index has been called to merge in the base index as well. The new fsmonitor_dirty is kept from being leaked by dint of being cleaned up in post_read_index_from, which is guaranteed to be called after do_read_index in read_index_from.

2017-10-07read_cache: roll back lock in `update_index_if_able()`Libravatar Martin Ågren1-0/+4
`update_index_if_able()` used to always commit the lock or roll it back. Commit 03b866477 (read-cache: new API write_locked_index instead of write_index/write_cache, 2014-06-13) stopped rolling it back in case a write was not even attempted. This change in behavior is not motivated in the commit message and appears to be accidental: the `else`-path was removed, although that changed the behavior in case the `if` shortcuts. Reintroduce the rollback and document this behavior. While at it, move the documentation on this function from the function definition to the function declaration in cache.h. If `write_locked_index(..., COMMIT_LOCK)` fails, it will roll back the lock for us (see the previous commit).

2017-10-07read-cache: leave lock in right state in `write_locked_index()`Libravatar Martin Ågren1-0/+4
If the original version of `write_locked_index()` returned with an error, it didn't roll back the lockfile unless the error occured at the very end, during closing/committing. See commit 03b866477 (read-cache: new API write_locked_index instead of write_index/write_cache, 2014-06-13). In commit 9f41c7a6b (read-cache: close index.lock in do_write_index, 2017-04-26), we learned to close the lock slightly earlier in the callstack. That was mostly a side-effect of lockfiles being implemented using temporary files, but didn't cause any real harm. Recently, commit 076aa2cbd (tempfile: auto-allocate tempfiles on heap, 2017-09-05) introduced a subtle bug. If the temporary file is deleted (i.e., the lockfile is rolled back), the tempfile-pointer in the `struct lock_file` will be left dangling. Thus, an attempt to reuse the lockfile, or even just to roll it back, will induce undefined behavior -- most likely a crash. Besides not crashing, we clearly want to make things consistent. The guarantees which the lockfile-machinery itself provides is A) if we ask to commit and it fails, roll back, and B) if we ask to close and it fails, do _not_ roll back. Let's do the same for consistency. Do not delete the temporary file in `do_write_index()`. One of its callers, `write_locked_index()` will thereby avoid rolling back the lock. The other caller, `write_shared_index()`, will delete its temporary file anyway. Both of these callers will avoid undefined behavior (crashing). Teach `write_locked_index(..., COMMIT_LOCK)` to roll back the lock before returning. If we have already succeeded and committed, it will be a noop. Simplify the existing callers where we now have a superfluous call to `rollback_lockfile()`. That should keep future readers from wondering why the callers are inconsistent.

2017-10-07read-cache: drop explicit `CLOSE_LOCK`-flagLibravatar Martin Ågren1-3/+2
`write_locked_index()` takes two flags: `COMMIT_LOCK` and `CLOSE_LOCK`. At most one is allowed. But it is also possible to use no flag, i.e., `0`. But when `write_locked_index()` calls `do_write_index()`, the temporary file, a.k.a. the lockfile, will be closed. So passing `0` is effectively the same as `CLOSE_LOCK`, which seems like a bug. We might feel tempted to restructure the code in order to close the file later, or conditionally. It also feels a bit unfortunate that we simply "happen" to close the lock by way of an implementation detail of lockfiles. But note that we need to close the temporary file before `stat`-ing it, at least on Windows. See 9f41c7a6b (read-cache: close index.lock in do_write_index, 2017-04-26). Drop `CLOSE_LOCK` and make it explicit that `write_locked_index()` always closes the lock. Whether it is also committed is governed by the remaining flag, `COMMIT_LOCK`. This means we neither have nor suggest that we have a mode to write the index and leave the file open. Whatever extra contents we might eventually want to write, we should probably write it from within `write_locked_index()` itself anyway.

2017-10-01fsmonitor: teach git to optionally utilize a file system monitor to speed up ↵Libravatar Ben Peart1-2/+8
detecting new or changed files. When the index is read from disk, the fsmonitor index extension is used to flag the last known potentially dirty index entries. The registered core.fsmonitor command is called with the time the index was last updated and returns the list of files changed since that time. This list is used to flag any additional dirty cache entries and untracked cache directories. We can then use this valid state to speed up preload_index(), ie_match_stat(), and refresh_cache_ent() as they do not need to lstat() files to detect potential changes for those entries marked CE_FSMONITOR_VALID. In addition, if the untracked cache is turned on valid_cached_dir() can skip checking directories for new or changed files as fsmonitor will invalidate the cache only for those directories that have been identified as having potential changes. To keep the CE_FSMONITOR_VALID state accurate during git operations; when git updates a cache entry to match the current state on disk, it will now set the CE_FSMONITOR_VALID bit. Inversely, anytime git changes a cache entry, the CE_FSMONITOR_VALID bit is cleared and the corresponding untracked cache directory is marked invalid.

2017-09-27git: add --no-optional-locks optionLibravatar Jeff King1-0/+6
Some tools like IDEs or fancy editors may periodically run commands like "git status" in the background to keep track of the state of the repository. Some of these commands may refresh the index and write out the result in an opportunistic way: if they can get the index lock, then they update the on-disk index with any updates they find. And if not, then their in-core refresh is lost and just has to be recomputed by the next caller. But taking the index lock may conflict with other operations in the repository. Especially ones that the user is doing themselves, which _aren't_ opportunistic. In other words, "git status" knows how to back off when somebody else is holding the lock, but other commands don't know that status would be happy to drop the lock if somebody else wanted it. There are a couple possible solutions: 1. Have some kind of "pseudo-lock" that allows other commands to tell status that they want the lock. This is likely to be complicated and error-prone to implement (and maybe even impossible with just dotlocks to work from, as it requires some inter-process communication). 2. Avoid background runs of commands like "git status" that want to do opportunistic updates, preferring instead plumbing like diff-files, etc. This is awkward for a couple of reasons. One is that "status --porcelain" reports a lot more about the repository state than is available from individual plumbing commands. And two is that we actually _do_ want to see the refreshed index. We just don't want to take a lock or write out the result. Whereas commands like diff-files expect us to refresh the index separately and write it to disk so that they can depend on the result. But that write is exactly what we're trying to avoid. 3. Ask "status" not to lock or write the index. This is easy to implement. The big downside is that any work done in refreshing the index for such a call is lost when the process exits. So a background process may end up re-hashing a changed file multiple times until the user runs a command that does an index refresh themselves. This patch implements the option 3. The idea (and the test) is largely stolen from a Git for Windows patch by Johannes Schindelin, 67e5ce7f63 (status: offer *not* to lock the index and update it, 2016-08-12). The twist here is that instead of making this an option to "git status", it becomes a "git" option and matching environment variable. The reason there is two-fold: 1. An environment variable is carried through to sub-processes. And whether an invocation is a background process or not should apply to the whole process tree. So you could do "git --no-optional-locks foo", and if "foo" is a script or alias that calls "status", you'll still get the effect. 2. There may be other programs that want the same treatment. I've punted here on finding more callers to convert, since "status" is the obvious one to call as a repeated background job. But "git diff"'s opportunistic refresh of the index may be a good candidate. The test is taken from 67e5ce7f63, and it's worth repeating Johannes's explanation: Note that the regression test added in this commit does not *really* verify that no index.lock file was written; that test is not possible in a portable way. Instead, we verify that .git/index is rewritten *only* when `git status` is run without `--no-optional-locks`.

2017-09-14pack: make packed_git_mru global a value instead of a pointerLibravatar Jonathan Nieder1-2/+2
The MRU cache that keeps track of recently used packs is represented using two global variables: struct mru packed_git_mru_storage; struct mru *packed_git_mru = &packed_git_mru_storage; Callers never assign to the packed_git_mru pointer, though, so we can simplify by eliminating it and using &packed_git_mru_storage (renamed to &packed_git_mru) directly. This variable is only used by the packfile subsystem, making this a relatively uninvasive change (and any new unadapted callers would trigger a compile error).
