Patrick Steinhardt 038f0e1b 2016-11-02T08:49:24 global: reset global state on shutdown without threading When threading is not enabled for libgit2, we keep global state in a simple static variable. When libgit2 is shut down, we clean up the global state by freeing the global state's dynamically allocated memory. When libgit2 is built with threading, we additionally free the thread-local storage and thus completely remove the global state. In a non-threaded build, though, we simply leave the global state as-is, which may result in an error upon reinitializing libgit2. Fix the issue by zeroing out the variable on a shutdown, thus returning it to its initial state.
Patrick Steinhardt 59c6c286 2016-10-27T12:31:17 global: synchronize initialization and shutdown with pthreads When trying to initialize and tear down global data structures from different threads at once with `git_libgit2_init` and `git_libgit2_shutdown`, we race around initializing data. While we use `pthread_once` to assert that we only initilize data a single time, we actually reset the `pthread_once_t` on the last call to `git_libgit2_shutdown`. As resetting this variable is not synchronized with other threads trying to access it, this is actually racy when one thread tries to do a complete shutdown of libgit2 while another thread tries to initialize it. Fix the issue by creating a mutex which synchronizes `init_once` and the library shutdown.

Edward Thomson aae89534 2016-10-09T12:51:48 Merge pull request #3956 from pks-t/pks/object-parsing-hardening Object parsing hardening
Patrick Steinhardt a719ef5e 2016-10-07T09:31:41 commit: always initialize commit message When parsing a commit, we will treat all bytes left after parsing the headers as the commit message. When no bytes are left, we leave the commit's message uninitialized. While uncommon to have a commit without message, this is the right behavior as Git unfortunately allows for empty commit messages. Given that this scenario is so uncommon, most programs acting on the commit message will never check if the message is actually set, which may lead to errors. To work around the error and not lay the burden of checking for empty commit messages to the developer, initialize the commit message with an empty string when no commit message is given.
Edward Thomson 45dc219f 2016-10-07T16:01:28 Merge pull request #3921 from libgit2/cmn/walk-limit-enough Improve revision walk preparation logic
Patrick Steinhardt 4974e3a5 2016-10-07T09:18:55 tree: validate filename and OID length when parsing object When parsing tree entries from raw object data, we do not verify that the tree entry actually has a filename as well as a valid object ID. Fix this by asserting that the filename length is non-zero as well as asserting that there are at least `GIT_OID_RAWSZ` bytes left when parsing the OID.
Carlos Martín Nieto fedc05c8 2016-10-06T18:13:34 revwalk: don't show commits that become uninteresting after being enqueued When we read from the list which `limit_list()` gives us, we need to check that the commit is still interesting, as it might have become uninteresting after it was added to the list.
Arthur Schreiber ab96ca55 2016-10-06T13:15:31 Make sure we use the `C` locale for `regcomp` on macOS.
Carlos Martín Nieto 3cc5ec94 2016-10-05T12:57:53 rebase: don't ask for time sorting `git-rebase--merge` does not ask for time sorting, but uses the default. We now produce the same default time-ordered output as git, so make us of that since it's not always the same output as our time sorting.
Carlos Martín Nieto 82d4c0e6 2016-10-05T12:55:53 revwalk: update the description for the default sorting It changed from implementation-defined to git's default sorting, as there are systems (e.g. rebase) which depend on this order. Also specify more explicitly how you can get git's "date-order".
Carlos Martín Nieto ea1ceb7f 2016-10-05T12:23:26 revwalk: remove a useless enqueueing phase for topological and default sorting After `limit_list()` we already have the list in time-sorted order, which is what we want in the "default" case. Enqueueing into the "unsorted" list would just reverse it, and the topological sort will do its own sorting if it needs to.
Carlos Martín Nieto 9db367bf 2016-09-27T16:14:42 revwalk: get rid of obsolete marking code We've now moved to code that's closer to git and produces the output during the preparation phase, so we no longer process the commits as part of generating the output. This makes a chunk of code redundant, as we're simply short-circuiting it by detecting we've processed the commits alrady.
Carlos Martín Nieto e93b7e32 2016-09-27T13:35:48 revwalk: style change Change the condition for returning 0 more in line with that we write elsewhere in the library.
Carlos Martín Nieto 5e2a29a7 2016-09-27T13:11:47 commit_list: fix the date comparison function This returns the integer-cast truth value comparing the dates. What we want instead of a (-1, 0, 1) output depending on how they compare.
Carlos Martín Nieto 48c64362 2016-09-27T11:59:24 revwalk: port over the topological sorting After porting over the commit hiding and selection we were still left with mistmaching output due to the topologial sort. This ports the topological sorting code to make us match with our equivalent of `--date-order` and `--topo-order` against the output from `rev-list`.
Carlos Martín Nieto 938f8e32 2016-09-23T13:25:35 pqueue: support not having a comparison function In this case, we simply behave like a vector.
Carlos Martín Nieto 0bd43371 2016-09-23T12:42:33 vector, pqueue: add git_vector_reverse and git_pqueue_reverse This is a convenience function to reverse the contents of a vector and a pqueue in-place. The pqueue function is useful in the case where we're treating it as a LIFO queue.
Carlos Martín Nieto 6708618c 2016-07-21T01:24:12 revwalk: get closer to git We had some home-grown logic to figure out which objects to show during the revision walk, but it was rather inefficient, looking over the same list multiple times to figure out when we had run out of interesting commits. We now use the lists in a smarter way. We also introduce the slop mechanism to determine when to stpo looking. When we run out of interesting objects, we continue preparing the walk for another 5 rounds in order to make it less likely that we miss objects in situations with complex graphs.
Edward Thomson 9fbbb0ee 2016-10-01T19:32:16 Merge pull request #3931 from libgit2/ethomson/checkout_dont_calculate_oid_for_dirs checkout: don't try to calculate oid for directories
Edward Thomson 955c99c2 2016-09-14T10:28:24 checkout: don't try to calculate oid for directories When trying to determine if we can safely overwrite an existing workdir item, we may need to calculate the oid for the workdir item to determine if its identical to the old side (and eligible for removal). We previously did this regardless of the type of entry in the workdir; if it was a directory, we would open(2) it and then try to read(2). The read(2) of a directory fails on many platforms, so we would treat it as if it were unmodified and continue to perform the checkout. On FreeBSD, you _can_ read(2) a directory, so this pattern failed. We would calculate an oid from the data read and determine that the directory was modified and would therefore generate a checkout conflict. This reliance on read(2) is silly (and was most likely accidentally giving us the behavior we wanted), we should be explicit about the directory test.

Edward Thomson adedac5a 2016-09-02T02:03:45 diff: treat binary patches with no data special When creating and printing diffs, deal with binary deltas that have binary data specially, versus diffs that have a binary file but lack the actual binary data.
Edward Thomson f4e3dae7 2016-09-02T11:26:16 diff_print: change test for skipping binary printing Instead of skipping printing a binary diff when there is no data, skip printing when we have a status of `UNMODIFIED`. This is more in-line with our internal data model and allows us to expand the notion of binary data. In the future, there may have no data because the files were unmodified (there was no data to produce) or it may have no data because there was no data given to us in a patch. We want to treat these cases separately.
Edward Thomson 4bfd7c63 2016-09-01T16:55:27 patch: error on diff callback failure
Patrick Steinhardt 4b34f687 2016-09-01T15:14:25 patch_generate: only calculate binary diffs if requested When generating diffs for binary files, we load and decompress the blobs in order to generate the actual diff, which can be very costly. While we cannot avoid this for the case when we are called with the `GIT_DIFF_SHOW_BINARY` flag, we do not have to load the blobs in the case where this flag is not set, as the caller is expected to have no interest in the actual content of binary files. Fix the issue by only generating a binary diff when the caller is actually interested in the diff. As libgit2 uses heuristics to determine that a blob contains binary data by inspecting its size without loading from the ODB, this saves us quite some time when diffing in a repository with binary files.

Patrick Steinhardt b1453601 2016-08-17T11:38:26 transports: http: reset `connected` flag when closing transport
Patrick Steinhardt c4cba4e9 2016-08-17T11:00:05 transports: http: reset `connected` flag when re-connecting transport When calling `http_connect` on a subtransport whose stream is already connected, we first close the stream in case no keep-alive is in use. When doing so, we do not reset the transport's connection state, though. Usually, this will do no harm in case the subsequent connect will succeed. But when the connection fails we are left with a substransport which is tagged as connected but which has no valid stream attached. Fix the issue by resetting the subtransport's connected-state when closing its stream in `http_connect`.
Patrick Steinhardt fcb2c1c8 2016-08-12T09:06:15 ignore: allow unignoring basenames in subdirectories The .gitignore file allows for patterns which unignore previous ignore patterns. When unignoring a previous pattern, there are basically three cases how this is matched when no globbing is used: 1. when a previous file has been ignored, it can be unignored by using its exact name, e.g. foo/bar !foo/bar 2. when a file in a subdirectory has been ignored, it can be unignored by using its basename, e.g. foo/bar !bar 3. when all files with a basename are ignored, a specific file can be unignored again by specifying its path in a subdirectory, e.g. bar !foo/bar The first problem in libgit2 is that we did not correctly treat the second case. While we verified that the negative pattern matches the tail of the positive one, we did not verify if it only matches the basename of the positive pattern. So e.g. we would have also negated a pattern like foo/fruz_bar !bar Furthermore, we did not check for the third case, where a basename is being unignored in a certain subdirectory again. Both issues are fixed with this commit.

Patrick Steinhardt b9895144 2016-08-08T14:47:32 stransport: do not use `git_stream_free` on uninitialized stransport When failing to initialize a new stransport stream, we try to release already allocated memory by calling out to `git_stream_free`, which in turn called out to the stream's `free` function pointer. As we only initialize the function pointer later on, this leads to a `NULL` pointer exception. Furthermore, plug another memory leak when failing to create the SSL context.

Edward Thomson 031d34b7 2016-07-29T12:59:42 sysdir: use the standard `init` pattern Don't try to determine when sysdirs are uninitialized. Instead, simply initialize them all at `git_libgit2_init` time and never try to reinitialize, except when consumers explicitly call `git_sysdir_set`. Looking at the buffer length is especially problematic, since there may no appropriate path for that value. (For example, the Windows-specific programdata directory has no value on non-Windows machines.) Previously we would continually trying to re-lookup these values, which could get racy if two different threads are each calling `git_sysdir_get` and trying to lookup / clear the value simultaneously.

Patrick Steinhardt 1eee631d 2016-08-04T13:45:28 refspec: do not set empty rhs for fetch refspecs According to git-fetch(1), "[t]he colon can be omitted when <dst> is empty." So according to git, the refspec "refs/heads/master" is the same as the refspec "refs/heads/master:" when fetching changes. When trying to fetch from a remote with a trailing colon with libgit2, though, the fetch actually fails while it works when the trailing colon is left out. So obviously, libgit2 does _not_ treat these two refspec formats the same for fetches. The problem results from parsing refspecs, where the resulting refspec has its destination set to an empty string in the case of a trailing colon and to a `NULL` pointer in the case of no trailing colon. When passing this to our DWIM machinery, the empty string gets translated to "refs/heads/", which is simply wrong. Fix the problem by having the parsing machinery treat both cases the same for fetch refspecs.

David Turner d81cb2e4 2016-07-15T13:32:23 remote: Handle missing config values when deleting a remote Somehow I ended up with the following in my ~/.gitconfig: [branch "master"] remote = origin merge = master rebase = true I assume something went crazy while I was running the git.git tests some time ago, and that I never noticed until now. This is not a good configuration, but it shouldn't cause problems. But it does. Specifically, if you have this in your config, and you perform the following set of actions: create a remote fetch from that remote create a branch off of the remote master branch called "master" delete the branch delete the remote The remote delete fails with the message "Could not find key 'branch.master.rebase' to delete". This is because it's iterating over the config entries (including the ones in the global config) and believes that there is a master branch which must therefore have these config keys. https://github.com/libgit2/libgit2/issues/3856

Edward Thomson 59a0005d 2016-06-29T10:01:26 Merge pull request #3813 from stinb/submodule-update-fetch submodule: Try to fetch when update fails to find the target commit.
Patrick Steinhardt 21766702 2016-06-27T15:20:20 blame: do not decrement commit refcount in make_origin When we create a blame origin, we try to look up the blob that is to be blamed at a certain revision. When this lookup fails, e.g. because the file did not exist at that certain revision, we fail to create the blame origin and return `NULL`. The blame origin that we have just allocated is thereby free'd with `origin_decref`. The `origin_decref` function does not only decrement reference counts for the blame origin, though, but also for its commit and blob. When this is done in the error case, we will cause an uneven reference count for these objects. This may result in hard-to-debug failures at seemingly unrelated code paths, where we try to access these objects when they in fact have already been free'd. Fix the issue by refactoring `make_origin` such that we only allocate the object after the only function that may fail so that we do not have to call `origin_decref` at all. Also fix the `pass_blame` function, which indirectly calls `make_origin`, to free the commit when `make_origin` failed.

Josh Triplett 2b490284 2016-06-24T15:59:37 find_repo: Clean up and simplify logic find_repo had a complex loop and heavily nested conditionals, making it difficult to follow. Simplify this as much as possible: - Separate assignments from conditionals. - Check the complex loop condition in the only place it can change. - Break out of the loop on error, rather than going through the rest of the loop body first. - Handle error cases by immediately breaking, rather than nesting conditionals. - Free repo_link unconditionally on the way out of the function, rather than in multiple places. - Add more comments on the remaining complex steps.
Josh Triplett 0dd98b69 2016-04-03T17:22:07 Add GIT_REPOSITORY_OPEN_FROM_ENV flag to respect $GIT_* environment vars git_repository_open_ext provides parameters for the start path, whether to search across filesystems, and what ceiling directories to stop at. git commands have standard environment variables and defaults for each of those, as well as various other parameters of the repository. To avoid duplicate environment variable handling in users of libgit2, add a GIT_REPOSITORY_OPEN_FROM_ENV flag, which makes git_repository_open_ext automatically handle the appropriate environment variables. Commands that intend to act just like those built into git itself can use this flag to get the expected default behavior. git_repository_open_ext with the GIT_REPOSITORY_OPEN_FROM_ENV flag respects $GIT_DIR, $GIT_DISCOVERY_ACROSS_FILESYSTEM, $GIT_CEILING_DIRECTORIES, $GIT_INDEX_FILE, $GIT_NAMESPACE, $GIT_OBJECT_DIRECTORY, and $GIT_ALTERNATE_OBJECT_DIRECTORIES. In the future, when libgit2 gets worktree support, git_repository_open_env will also respect $GIT_WORK_TREE and $GIT_COMMON_DIR; until then, git_repository_open_ext with this flag will error out if either $GIT_WORK_TREE or $GIT_COMMON_DIR is set.

GIT_REPOSITORY_OPEN_BARE avoids appending /.git, but opens the repository in bare mode even if it has a working directory. To support the semantics git uses when given $GIT_DIR in the environment, provide a new GIT_REPOSITORY_OPEN_NO_DOTGIT flag to not try appending /.git.

A ceiling directory matching the starting directory will not prevent git from finding a repository in the starting directory or a parent directory. libgit2 handled the former case correctly, but differed from git in the latter case: given a ceiling directory matching the starting directory, but no repository at the starting directory, libgit2 would stop the search at that point rather than finding a repository in a parent directory. Test case using git command-line tools: /tmp$ git init x Initialized empty Git repository in /tmp/x/.git/ /tmp$ cd x/ /tmp/x$ mkdir subdir /tmp/x$ cd subdir/ /tmp/x/subdir$ GIT_CEILING_DIRECTORIES=/tmp/x git rev-parse --git-dir fatal: Not a git repository (or any of the parent directories): .git /tmp/x/subdir$ GIT_CEILING_DIRECTORIES=/tmp/x/subdir git rev-parse --git-dir /tmp/x/.git Fix the testsuite to test this case (in one case fixing a test that depended on the current behavior), and then fix find_repo to handle this case correctly. In the process, simplify and document the logic in find_repo(): - Separate the concepts of "currently checking a .git directory" and "number of iterations left before going further counts as a search" into two separate variables, in_dot_git and min_iterations. - Move the logic to handle in_dot_git and append /.git to the top of the loop. - Only search ceiling_dirs and find ceiling_offset after running out of min_iterations; since ceiling_offset only tracks the longest matching ceiling directory, if ceiling_dirs contained both the current directory and a parent directory, this change makes find_repo stop the search at the parent directory.

Patrick Steinhardt 8aaa9fb6 2016-06-20T18:21:42 win32: rename pthread.{c,h} to thread.{c,h} The old pthread-file did re-implement the pthreads API with exact symbol matching. As the thread-abstraction has now been split up between Unix- and Windows-specific files within the `git_` namespace to avoid symbol-clashes between libgit2 and pthreads, the rewritten wrappers have nothing to do with pthreads anymore. Rename the Windows-specific pthread-files to honor this change.
