Carlos Martín Nieto 6c5eaead 2015-06-20T12:36:58 tests: plug leaks in the racy test
Carlos Martín Nieto 74975846 2015-06-18T14:22:10 index: check racily clean entries more thoroughly When an entry has a racy timestamp, we need to check whether the file itself has changed since we put its entry in the index. Only then do we smudge the size field to force a check the next time around.
Carlos Martín Nieto ff475375 2015-06-17T14:34:10 diff: check files with the same or newer timestamps When a file on the workdir has the same or a newer timestamp than the index, we need to perform a full check of the contents, as the update of the file may have happened just after we wrote the index. The iterator changes are such that we can reach inside the workdir iterator from the diff, though it may be better to have an accessor instead of moving these structs into the header.
Carlos Martín Nieto e96a97f1 2015-06-20T23:17:42 Merge pull request #3233 from ethomson/status_typechange Don't propagate workdir's mode to the index during diff's update index
Edward Thomson 96dd171e 2015-06-19T08:32:26 diff: preserve original mode in the index When updating the index during a diff, preserve the original mode, which prevents us from dropping the mode to what we have interpreted as on our system (eg, what the working directory claims it to be, which may be a lie on some systems.)
Edward Thomson fc656802 2015-06-19T08:31:07 status: test that symlinks don't lose their mode Test to ensure that when status updates an index, it does not alter the original mode for file types that are not supported (eg, symlinks on Windows).

Pierre-Olivier Latour 07ea3a7f 2015-06-20T10:57:03 Fixed index being double-freed in stash tests
Carlos Martín Nieto 624c949f 2015-06-20T16:17:28 index: make relative comparison use the checksum as well This is used by the submodule in order to figure out if the index has changed since it last read it. Using a timestamp is racy, so let's make it use the checksum, just like we now do for reloading the index itself.

Carlos Martín Nieto 863dd89a 2015-06-18T12:45:40 tests: tick over five seconds instead of one When ticking over one second, it can happen that the actual time ticks over the same second between the time that we undermine our own race protections and the time in which we perform the index update. Such timing would make the time in the entries match the index' timestamp and we have not gained anything. Ticking over five seconds makes it so that if real-time rolls over that second, our index is still ahead. This is still suboptimal as we're dealing with timing, but five seconds should be long enough for any reasonable test runner to finish the tests.
Carlos Martín Nieto 5e947c91 2015-06-19T22:05:08 index: use the checksum to check whether it's been modified We currently use a timetamp to check whether an index file has been modified since we last read it, but this is racy. If two updates happen in the same second and we read after the first one, we won't detect the second one. Instead read the SHA-1 checksum of the file, which are its last 20 bytes which gives us a sure-fire way to detect whether the file has changed since we last read it. As we're now keeping track of it, expose an accessor to this data.
Carlos Martín Nieto 46c84c72 2015-06-19T21:56:42 index: user a better assertion when comparing sizes This will tell us which numbers we were trying to compare, rather than just telling us that they're different.
Marius Ungureanu e488bef4 2015-06-19T12:53:37 Quote LIBSSH2_LIBRARIES call Credits to @directhex It is possible for PKG_CHECK_MODULES(LIBSSH2 libssh2) to LIBSSH2_LIBRARIES to a string with more than one library in it - e.g. if your libssh2 was built against libgcrypt, it will be "ssh2;gcrypt" Quoting the string is needed, or CHECK_LIBRARY_EXISTS will fail.

Carlos Martín Nieto 47a40d1d 2015-06-16T12:39:11 remote: return EINVALIDSPEC when given an empty URL This is what we used to return in the settter and there's tests in bindings which ask for this. There's no particular reason to stop doing so.
Carlos Martín Nieto aeb2b991 2015-06-16T09:20:36 Merge pull request #3221 from git-up/build_warnings Fixed Xcode 6.1 build warnings
Carlos Martín Nieto e44abe16 2015-06-16T08:51:45 tests: tick the index when we count OID calculations These tests want to test that we don't recalculate entries which match the index already. This is however something we force when truncating racily-clean entries. Tick the index forward as we know that we don't perform the modifications which the racily-clean code is trying to avoid.
Carlos Martín Nieto c4e6ab5f 2015-06-15T14:32:08 crlf: tick the index forward to work around racy-git behaviour In order to avoid racy-git, we zero out the file size for entries with the same timestamp as the index (or during the initial checkout). This is the case in a couple of crlf tests, as the code is fast enough to do everything in the same second. As we know that we do not perform the modification just after writing out the index, which is what this is designed to work around, tick the mtime of the index file such that it doesn't agree with the files anymore, and we do not zero out these entries.
Carlos Martín Nieto 316b820b 2015-06-15T09:55:40 index: zero the size of racily-clean entries If a file entry has the same timestamp as the index itself, it is considered racily-clean, as it may have been modified after the index was written, but during the same second. We take extra steps to check the contents, but this is just one part of avoiding races. For files which do have changes but have not been updated in the index, updating the on-disk index means updating its timestamp, which means we would no longer recognise these entries as racy and we would trust the timestamp to tell us whether they have changed. In order to work around this, git zeroes out the file-size field in entries with the same timestamp as the index in order to force the next diff to check the contents. Do so in libgit2 as well.
Carlos Martín Nieto 77596fcf 2015-06-15T09:51:34 diff: add failing test for racy-git in the index We update the index and then immediately change the contents of the file. This makes the diff think there are no changes, as the timestamp of the file agrees with the cached data. This is however a bug, as the file has obviously changed contents. The test is a bit fragile, as it assumes that the index writing and the following modification of the file happen in the same second, but it's enough to show the issue.

Carlos Martín Nieto 25bd0aaf 2015-06-15T13:28:08 path: remove unnecessary readdir_r usage Arguably all uses of readdir_r are unnecessary, but in this case especially so, as the directory handle only exists within this function, so we don't race with anybody.

Carlos Martín Nieto 65d69fe8 2015-06-11T08:24:58 commit: ignore multiple author fields Some tools create multiple author fields. git is rather lax when parsing them, although fsck does complain about them. This means that they exist in the wild. As it's not too taxing to check for them, and there shouldn't be a noticeable slowdown when dealing with correct commits, add logic to skip over these extra fields when parsing the commit.

Edward Thomson da6720fc 2015-06-10T09:02:54 Merge pull request #3201 from libgit2/cmn/coverity A few more fixes from coverity
Carlos Martín Nieto 0137aba5 2015-06-10T11:08:05 filter: close the descriptor in case of error When we hit an error writing to the next stream from a file, we jump to 'done' which currently skips over closing the file descriptor. Make sure to close the descriptor if it has been set to a valid value.
Carlos Martín Nieto 969d4b70 2015-06-10T10:59:56 object: correct the expected ID size in prefix lookup We take in a possibly partial ID by taking a length and working off of that to figure out whether to just look up the object or ask the backends for a prefix lookup. Unfortunately we've been checking the size against `GIT_OID_HEXSZ` which is the size of a *string* containing a full ID, whereas we need to check against the size we can have when it's a 20-byte array. Change the checks and comment to use `GIT_OID_RAWSZ` which is the correct size of a git_oid to have when full.
Carlos Martín Nieto 878293f7 2015-06-10T10:44:14 pack: use git_buf when building the index name The way we currently do it depends on the subtlety of strlen vs sizeof and the fact that .pack is one longer than .idx. Let's use a git_buf so we can express the manipulation we want much more clearly.
Carlos Martín Nieto ca2857d8 2015-06-10T10:30:08 merge: actually increment the counts, not the pointers `merge_diff_list_count_candidates()` takes pointers to the source and target counts, but when it comes time to increase them, we're increasing the pointer, rather than the value it's pointing to. Dereference the value to increase.

Carlos Martín Nieto 02980bdc 2015-06-09T16:53:07 Initialize a few variables Coverity complains about the git_rawobj ones because we use a loop in which we keep remembering the old version, and we end up copying our object as the base, so we want to have the data pointer be NULL.
Carlos Martín Nieto 81be2f46 2015-06-09T16:01:29 ssh: move NULL check to the free function Let `ssh_stream_free()` take a NULL stream, as free functions should, and remove the check from the connection setup. The connection setup would not need the check anyhow, as we always have a stream by the time we reach this code.

Carlos Martín Nieto aa57231f 2015-06-02T10:25:22 indexer: use lseek to extend the packfile We've been using `p_ftruncate()` to extend the packfile in order to mmap it and write the new data into it. This works well in the general case, but as truncation does not allocate space in the filesystem, it must do so when we write data to it. The only way the OS has to indicate a failure to allocate space is via SIGBUS which means we tried to write outside the file. This will cause everyone to crash as they don't expect to handle this signal. Switch to using `p_lseek()` and `p_write()` to extend the file in a way which tells the filesystem to allocate the space for the missing data. We can then be sure that we have space to write into.
Carlos Martín Nieto 10940736 2015-06-01T22:15:11 clone: fall back to copying when linking does not work We use heuristics to make a decent guess at when we can save time and space by linking object files during a clone. Unfortunately checking the device id isn't enough, as those would be the same during e.g. a bind-mount, but the OS still does not allow us to link between mounts of the same filesystem. If we fail to perform the links, fall back to copying the contents into a new file as a last attempt.
