Carlos Martín Nieto b31283a6 2016-12-12T17:09:12 refdb: disable concurrent compress in the threading tests on Windows This is far from an ideal situation, but this causes issues on Windows which make it harder to develop anything, as these tests hit issues which relate specifically to the Windows filesystem like permission errors for files we should be able to access. There is an issue likely related to the ordering of the repack, but there's enough noise that it does not currently help us to run this aspect of the test in CI.

Patrick Steinhardt ab0cc5a0 2016-11-25T14:58:16 clar: mark `cl_git_thread_check()` as inline The function `cl_git_thread_check()` is defined as static. As the function is defined in a header file which is included by our tests, this can result in warnings for every test file where `cl_git_thread_check` is never used. Fix the issue by marking it as inline instead.

Edward Thomson bbf22f82 2016-11-18T07:34:20 clar: Introduce assertion helpers for threads Don't `cl_git_pass` in a child thread. When the assertion fails, clar will `longjmp` to its error handler, but: > The effect of a call to longjmp() where initialization of the jmp_buf > structure was not performed in the calling thread is undefined. Instead, set up an error context that threads can populate, and the caller can check.
Edward Thomson 99479062 2016-11-18T16:50:34 core::init tests: reverse init/shutdown We want a predictable number of initializations in our multithreaded init test, but we also want to make sure that we have _actually_ initialized `git_libgit2_init` before calling `git_thread_create` (since it now has a sanity check that `git_libgit2_init` has been called). Since `git_thread_create` is internal-only, keep this sanity check. Flip the invocation so that we `git_libgit2_init` before our thread tests and `git_libgit2_shutdown` again after.
Edward Thomson 82f15896 2016-11-18T07:19:22 threads: introduce `git_thread_exit` Introduce `git_thread_exit`, which will allow threads to terminate at an arbitrary time, returning a `void *`. On Windows, this means that we need to store the current `git_thread` in TLS, so that we can set its `return` value when terminating. We cannot simply use `ExitThread`, since Win32 returns `DWORD`s from threads; we return `void *`.

Patrick Steinhardt 5cbd5260 2016-11-11T11:37:00 curl_stream: use CURLINFO_ACTIVESOCKET if curl is recent enough The `CURLINFO_LASTSOCKET` information has been deprecated since curl version 7.45.0 as it may result in an overflow in the returned socket on certain systems, most importantly on 64 bit Windows. Instead, a new call `CURLINFO_ACTIVESOCKET` has been added which instead returns a `curl_socket_t`, which is always sufficiently long to store a socket. As we need to provide backwards compatibility with curl versions smaller than 7.45.0, alias CURLINFO_ACTIVESOCKET to CURLINFO_LASTSOCKET on platforms without CURLINFO_ACTIVESOCKET.

Carlos Martín Nieto 89776585 2016-11-14T12:44:52 tree: look for conflicts in the new tree when updating We look at whether we're trying to replace a blob with a tree during the update phase, but we fail to look at whether we've just inserted a blob where we're now trying to insert a tree. Update the check to look at both places. The test for this was previously succeeding due to the bu where we did not look at the sorted output.
Carlos Martín Nieto b85929c5 2016-11-14T12:44:01 tree: use the sorted update list in our loop The loop is made with the assumption that the inputs are sorted and not using it leads to bad outputs.
Carlos Martín Nieto 1d41b86c 2016-11-14T12:22:20 tree: add a failing test for unsorted input We do not currently use the sorted version of this input in the function, which means we produce bad results.
Carlos Martín Nieto aef54a46 2016-11-14T11:29:40 refdb: use a constant for the number of per-thread creations/deletes
Carlos Martín Nieto ce5553d4 2016-03-10T22:01:09 refdb: bubble up locked files on the read side On Windows we can find locked files even when reading a reference or the packed-refs file. Bubble up the error in this case as well to allow callers on Windows to retry more intelligently.
Carlos Martín Nieto 7c32d874 2016-03-10T12:27:07 refdb: expect threaded test deletes to race At times we may try to delete a reference which a different thread has already taken care of.
Carlos Martín Nieto 33248b9e 2016-03-10T12:22:34 refdb: remove a check-delete race when removing a loose ref It does not help us to check whether the file exists before trying to unlink it since it might be gone by the time unlink is called. Instead try to remove it and handle the resulting error if it did not exist.
Carlos Martín Nieto 40ffa07f 2015-12-31T14:51:42 sortedcache: check file size after opening the file Checking the size before we open the file descriptor can lead to the file being replaced from under us when renames aren't quite atomic, so we can end up reading too little of the file, leading to us thinking the file is corrupted.
Carlos Martín Nieto 26416f6d 2015-12-24T17:51:19 refdb: add retry logic to the threaded tests The logic simply consists of retrying for as long as the library says the data is locked, but it eventually gets through.
Carlos Martín Nieto 2e09106e 2015-12-24T17:49:49 refdb: bubble up the error code when compressing the db This allows the caller to know the errors was e.g. due to the packed-refs file being already locked and they can try again later.
Carlos Martín Nieto dd1ca6f1 2015-12-24T17:38:41 refdb: refactor the lockfile cleanup We can reduce the duplication by cleaning up at the beginning of the loop, since it's something we want to do every time we continue.
Carlos Martín Nieto 7ea4710a 2015-12-24T17:30:24 refdb: don't report failure for expected errors There might be a few threads or processes working with references concurrently, so fortify the code to ignore errors which come from concurrent access which do not stop us from continuing the work. This includes ignoring an unlinking error. Either someone else removed it or we leave the file around. In the former case the job is done, and in the latter case, the ref is still in a valid state.
Carlos Martín Nieto f94825c1 2015-12-24T17:21:51 fileops: save errno and report file existence We need to save the errno, lest we clobber it in the giterr_set() call. Also add code for reporting that a path component is missing, which is a distinct failure mode.
Carlos Martín Nieto 2d9aec99 2015-12-24T14:01:38 refdb: make ref deletion after pack safer In order not to undo concurrent modifications to references, we must make sure that we only delete a loose reference if it still has the same value as when we packed it. This means we need to lock it and then compare the value with the one we put in the packed file.
Carlos Martín Nieto 9914efec 2015-12-24T14:00:48 refdb: bubble up errors We can get useful information like GIT_ELOCKED out of this instead of just -1.
Carlos Martín Nieto 7da4c429 2015-12-24T12:37:41 refdb: adjust the threading tests to what we promise We say it's going to work if you use a different repository in each thread. Let's do precisely that in our code instead of hoping re-using the refdb is going to work. This test does fail currently, surfacing existing bugs.
Patrick Steinhardt 2382b0f8 2016-11-11T15:50:14 test: discover: move layout creation into test initializer
Patrick Steinhardt 0f316096 2016-11-11T16:55:33 repository: do not interpret all files as gitlinks in discovery When trying to find a discovery, we walk up the directory structure checking if there is a ".git" file or directory and, if so, check its validity. But in the case that we've got a ".git" file, we do not want to unconditionally assume that the file is in fact a ".git" file and treat it as such, as we would error out if it is not. Fix the issue by only treating a file as a gitlink file if it ends with "/.git". This allows users of the function to discover a repository by handing in any path contained inside of a git repository.

Josh Triplett c9e967a1 2016-11-10T03:51:12 git_repository_open_ext: fix handling of $GIT_NAMESPACE The existing code would set a namespace of "" (empty string) with GIT_NAMESPACE unset. In a repository where refs/heads/namespaces/ exists, that can produce incorrect results. Detect that case and avoid setting the namespace at all. Since that makes the last assignment to error conditional, and the previous assignment can potentially get GIT_ENOTFOUND, set error to 0 explicitly to prevent the call from incorrectly failing with GIT_ENOTFOUND.
Patrick Steinhardt b7822050 2016-11-11T11:25:39 Merge pull request #3993 from alexcrichton/fix-fault
Alex Crichton 5ca75fd5 2016-11-10T08:00:22 curl_stream: check for -1 after CURLINFO_LASTSOCKET We're recently trying to upgrade to the current master of libgit2 in Cargo but we're unfortunately hitting a segfault in one of our tests. This particular test is just a small smoke test that https works (e.g. it's configured in libgit2). It attempts to clone from a URL which simply immediately drops connections after they're accepted (e.g. terminate abnormally). We expect to see a standard error from libgit2 but unfortunately we're seeing a segfault. This segfault is happening inside of the `wait_for` function of `curl_stream.c` at the line `FD_SET(fd, &errfd)` because `fd` is -1. This ends up doing an out-of-bounds array access that faults the program. I tracked back to where this -1 came from to the line here (returned by `CURLINFO_LASTSOCKET`) and added a check to return an error.

John Fultz f9793884 2016-10-28T14:32:01 branch: fix forced branch creation on HEAD of a bare repo The code correctly detects that forced creation of a branch on a nonbare repo should not be able to overwrite a branch which is the HEAD reference. But there's no reason to prevent this on a bare repo, and in fact, git allows this. I.e., git branch -f master new_sha works on a bare repo with HEAD set to master. This change fixes that problem, and updates tests so that, for this case, both the bare and nonbare cases are checked for correct behavior.

Carlos Martín Nieto 2f3adf95 2016-11-02T12:35:46 openssl: use ASN1_STRING_get0_data when compiling against 1.1 For older versions we can fall back on the deprecated ASN1_STRING_data.
Carlos Martín Nieto f15eedb3 2016-11-02T12:28:25 openssl: recreate the OpenSSL 1.1 BIO interface for older versions We want to program against the interface, so recreate it when we compile against pre-1.1 versions.
Patrick Steinhardt 0cf15e39 2016-11-02T12:23:12 pack: fix race in pack_entry_find_offset In `pack_entry_find_offset`, we try to find the offset of a certain object in the pack file. To do so, we first assert if the packfile has already been opened and open it if not. Opening the packfile is guarded with a mutex, so concurrent access to this is in fact safe. What is not thread-safe though is our calculation of offsets inside the packfile. Assume two threads calling `pack_entry_find_offset` at the same time. We first calculate the offset and index location and only then determine if the pack has already been opened. If so, we re-calculate the offset and index address. Now the case for two threads: thread 1 first calculates the addresses and is subsequently suspended. The second thread will now call `pack_index_open` and initialize the pack file, calculating its addresses correctly. When the first thread is resumed now, he'll see that the pack file has already been initialized and will happily proceed with the addresses it has already calculated before the check. As the pack file was not initialized before, these addresses are bogus. Fix the issue by only calculating the addresses after having checked if the pack file is open.
Patrick Steinhardt 62494bf2 2016-11-02T09:38:40 transports: smart: abort receiving packets on end of stream When trying to receive packets from the remote, we loop until either an error distinct to `GIT_EBUFS` occurs or until we successfully parsed the packet. This does not honor the case where we are looping over an already closed socket which has no more data, leaving us in an infinite loop if we got a bogus packet size or if the remote hang up. Fix the issue by returning `GIT_EEOF` when we cannot read data from the socket anymore.
Patrick Steinhardt 61530c49 2016-11-01T16:56:07 transports: smart: abort ref announcement on early end of stream When reading a server's reference announcements via the smart protocol, we expect the server to send multiple flushes before the protocol is finished. If we fail to receive new data from the socket, we will only return an end of stream error if we have not seen any flush yet. This logic is flawed in that we may run into an infinite loop when receiving a server's reference announcement with a bogus flush packet. E.g. assume the last flushing package is changed to not be '0000' but instead any other value. In this case, we will still await one more flush package and ignore the fact that we are not receiving any data from the socket, causing an infinite loop. Fix the issue by always returning `GIT_EEOF` if the socket indicates an end of stream.

Patrick Steinhardt 1c33ecc4 2016-11-01T14:30:38 tests: core: test deinitialization and concurrent initialization Exercise the logic surrounding deinitialization of the libgit2 library as well as repeated concurrent de- and reinitialization. This tries to catch races and makes sure that it is possible to reinitialize libgit2 multiple times. After deinitializing libgit2, we have to make sure to setup options required for testing. Currently, this only includes setting up the configuration search path again. Before, this has been set up once in `tests/main.c`.
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.

Patrick Steinhardt 18c18e3d 2016-10-31T15:55:46 coverity: check for Coverity token only if necessary When running a Coverity build, we have to provide an authentication token in order to proof that we are actually allowed to run analysis in the name of a certain project. As this token should be secret, it is only set on the main repository, so when we were requested to run the Coverity script on another repository we do error out. But in fact we do also error out if the Coverity analysis should _not_ be run if there is no authentication token provided. Fix the issue by only checking for the authentication token after determining if analysis is indeed requested.
