90177111	2015-06-23T16:27:33	stash: save the workdir file when deleted in index When stashing the workdir tree, examine the index as well. Using a mechanism similar to `git_diff_tree_to_workdir_with_index` allows us to determine that a file was added in the index and subsequently modified in the working directory. Without examining the index, we would erroneously believe that this file was untracked and fail to include it in the working directory tree. Use a slightly modified `git_diff_tree_to_workdir_with_index` in order to avoid some of the behavior custom to `git diff`. In particular, be sure to include the working directory side of a file when it was deleted in the index.

83ba5e36	2015-06-22T18:43:13	diff_tform: remove reversed copy of delta merger Drop `git_diff__merge_like_cgit_reversed`, since it's a copy and paste mess of slightly incompatible changes.
16c73d38	2015-06-23T20:44:27	repository: check the format version This is something we do on re-init but not when opening a repository. This hasn't particularly mattered up to now as the version has been 0 ever since the first release of git, but the times, they're a-changing and we will soon see version 1 in the wild. We need to make sure we don't open those.
99e11cdd	2015-06-23T20:43:49	repository: don't error out if there is no version git will assume the repository format version is 0 if the value is not there. Do the same.
8d8a2eef	2015-06-15T11:14:40	Fixed GIT_DELTA_CONFLICTED not returned in some cases If an index entry for a file that is not in HEAD is in conflicted state, when diffing HEAD with the index, the status field of the corresponding git_diff_delta was incorrectly reported as GIT_DELTA_ADDED instead of GIT_DELTA_CONFLICTED. This was due to handle_unmatched_new_item() initially setting the status to GIT_DELTA_CONFLICTED but then overriding it later with GIT_DELTA_ADDED.
cb63e7e8	2015-06-17T08:55:09	Explicitly handle GIT_DELTA_CONFLICTED in git_diff_merge() This fixes a bug where if a file was in conflicted state in either diff, it would not always remain in conflicted state in the merged diff.
146d0d08	2015-06-09T00:42:28	crlf: give Unix the glory of autocrlf=true Perform LF->CRLF for core.autocrlf=true on non-Win32 because core git does.

47e9a6cb	2015-06-08T15:58:54	crlf: use statistics to control to workdir filter Use statistics (like core git) to control the behavior of the to workdir CRLF filter.
0b6ed4f9	2015-06-22T11:24:20	Merge pull request #3240 from libgit2/cmn/commit-header-field commit: allow retrieving an arbitrary header field
a3f42fe8	2015-06-22T15:32:29	commit: allow retrieving an arbitrary header field This allows the user to look up fields which we don't parse in libgit2, and allows them to access gpgsig or mergetag fields if they wish to check the signature.
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.
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.
e35b947b	2015-06-21T01:06:20	Write modified index in git_stash_apply() Same as with git_stash_save(), there's no reason not to write the index to disk since it has been modified.
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.)
883cb642	2015-06-20T14:05:02	Merge pull request #3236 from libgit2/cmn/index-checksum Use the checksum to check whether an index has been modified
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.
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.

892abf93	2015-06-16T17:23:12	checkout: allow workdir to contain checkout target When checking out some file 'foo' that has been modified in the working directory, allow the checkout to proceed (do not conflict) if 'foo' is identical to the target of the checkout.
121c3171	2015-06-16T15:18:04	Introduce p_utimes and p_futimes Provide functionality to set the time on a filesystem entry, using utimes or futimes on POSIX type systems or SetFileTime on Win32.

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.
aeb2b991	2015-06-16T09:20:36	Merge pull request #3221 from git-up/build_warnings Fixed Xcode 6.1 build warnings
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.
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.

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.

8147b1af	2015-05-25T20:03:59	diff: introduce binary diff callbacks Introduce a new binary diff callback to provide the actual binary delta contents to callers. Create this data from the diff contents (instead of directly from the ODB) to support binary diffs including the workdir, not just things coming out of the ODB.
6d0a0aca	2015-06-11T23:20:28	Fixed some Secure Transport issues on OS X The read and write callbacks passed to SSLSetIOFuncs() have been rewritten to match the implementation used on opensource.apple.com and other open source projects like VLC. This change also fixes a bug where the read callback could get into an infinite loop when 0 bytes were read.
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.

3e8c5e45	2015-06-10T16:43:48	Merge pull request #3174 from libgit2/cmn/idx-fill-hole indexer: use lseek to extend the packfile
2eecc288	2015-06-10T14:43:49	Introduce `git_filter_list_contains` `git_filter_list_contains` can be used to query a filter list to determine if a given filter will be run.
50456801	2015-06-10T10:09:10	Fixed handling of GIT_DELTA_CONFLICTED in git_diff_find_similar() git_diff_find_similar() now ignores git_diff_delta records with a status of GIT_DELTA_CONFLICTED, which fixes a crash due to assert() being hit.
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.
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.
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.
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.
2d73075a	2015-06-10T10:23:08	cache: add a check for a failed allocation Rather minimal change, but it's the kind of thing we should do.
a166466c	2015-06-09T17:06:28	Merge pull request #3198 from libgit2/cmn/coverity A few fixes from Coverity
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.
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.

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.
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.
ec0c4c40	2015-05-04T11:59:20	remote: apply insteadOf configuration. A remote's URLs are now modified according to the url..insteadOf and url..pushInsteadOf configurations. This allows a user to replace URL prefixes by setting the corresponding keys. E.g. "url.foo.insteadOf = bar" would replace the prefix "bar" with the new prefix "foo".
75a4636f	2015-05-29T16:56:38	git__tolower: a tolower() that isn't dumb Some brain damaged tolower() implementations appear to want to take the locale into account, and this may require taking some insanely aggressive lock on the locale and slowing down what should be the most trivial of trivial calls for people who just want to downcase ASCII.
006548da	2015-05-29T16:07:51	git__strcasecmp: treat input bytes as unsigned Treat input bytes as unsigned before doing arithmetic on them, lest we look at some non-ASCII byte (like a UTF-8 character) as a negative value and perform the comparison incorrectly.
2c8550f0	2015-05-29T19:38:11	Merge pull request #3157 from mgorny/ssh_memory_auth Support getting SSH keys from memory, pt. 2
885b94aa	2015-05-28T15:26:13	Rename GIT_EMERGECONFLICT to GIT_ECONFLICT We do not error on "merge conflicts"; on the contrary, merge conflicts are a normal part of merging. We only error on "checkout conflicts", where a change exists in the index or the working directory that would otherwise be overwritten by performing the checkout. This may happen during merge (after the production of the new index that we're going to checkout) but it could happen during any checkout.

9b3e41f7	2015-05-19T18:29:15	index_add_all: remove conflicts when no wd file If there exists a conflict in the index, but no file in the working directory, this implies that the user wants to accept the resolution by removing the file. Thus, remove the conflict entry from the index, instead of trying to add a (nonexistent) file.
10549a2d	2015-05-19T18:26:04	Introduce `GIT_DIFF_FLAG_EXISTS` Mark the `old_file` and `new_file` sides of a delta with a new bit, `GIT_DIFF_FLAG_EXISTS`, that introduces that a particular side of the delta exists in the diff. This is useful for indicating whether a working directory item exists or not, in the presence of a conflict. Diff users may have previously used DELETED to determine this information.
253a05f7	2015-05-19T11:31:15	diff: prettify `maybe_modified` a little
9f545b9d	2015-05-19T11:23:59	introduce `git_index_entry_is_conflict` It's not always obvious the mapping between stage level and conflict-ness. More importantly, this can lead otherwise sane people to write constructs like `if (!git_index_entry_stage(entry))`, which (while technically correct) is unreadable. Provide a nice method to help avoid such messy thinking.
191e97a0	2015-05-18T18:15:17	diff conflicts: don't include incorrect ID Since a diff entry only concerns a single entry, zero the information for the index side of a conflict. (The index entry would otherwise erroneously include the lowest-stage index entry - generally the ancestor of a conflict.) Test that during status, the index side of the conflict is empty.
7877146f	2015-05-18T15:13:43	diff: for conflicts w/o workdir, blank nitem side Make sure that we provide a blanked nitem side when the item does not exist in the working directory.
7c948014	2015-05-14T14:00:29	diff/status: introduce conflicts When diffing against an index, return a new `GIT_DELTA_CONFLICTED` delta type for items that are conflicted. For a single file path, only one delta will be produced (despite the fact that there are multiple entries in the index). Index iterators now have the (optional) ability to return conflicts in the index. Prior to this change, they would be omitted, and callers (like diff) would omit conflicted index entries entirely.
d67f270e	2015-05-14T13:30:29	index: validate mode of new conflicts
3ab5a659	2015-05-14T12:54:39	index: remove error message in non-error remove If `git_index_remove_bypath` does no work, and returns an OK error code, it should not set an error message.
ecd60a56	2015-05-14T11:52:48	conflicts: when adding conflicts, remove staged When adding a conflict for some path, remove the staged entry. Otherwise, an illegal index (with both stage 0 and high-stage entries) would result.
1b6c26db	2015-05-13T17:47:26	diff: wrap the iterator functions Wrap the iterator current / advance functions so that we can extend them, but also handle GIT_ITEROVER cases in the iterator funcs instead of the callers.

c6e942fb	2015-05-17T15:19:22	remote: validate refspecs before adding to config When we moved from acting on the instance to acting on the configuration, we dropped the validation of the passed refspec, which can lead to writing an invalid refspec to the configuration. Bring that validation back.

5014fe95	2015-05-22T12:24:09	branch: error out if we cannot find the remote When we look for which remote corresponds to a remote-tracking branch, we look in the refspecs to see which ones matches. If none do, we should abort. We currently ignore the error message from this operation, so let's not do that anymore. As part of the test we're writing, let's test for the expected behaviour if we cannot find a refspec which tells us what the remote-tracking branch for a remote would look like.

Using a mechanism similar to `git_diff_tree_to_workdir_with_index` allows us to determine that a file was added in the index and subsequently modified in the working directory. Without examining the index, we would erroneously believe that this file was untracked and fail to include it in the working directory tree. Use a slightly modified `git_diff_tree_to_workdir_with_index` in order to avoid some of the behavior custom to `git diff`. In particular, be sure to include the working directory side of a file when it was deleted in the index.

Fixed GIT_DELTA_CONFLICTED not returned in some cases If an index entry for a file that is not in HEAD is in conflicted state, when diffing HEAD with the index, the status field of the corresponding git_diff_delta was incorrectly reported as GIT_DELTA_ADDED instead of GIT_DELTA_CONFLICTED. This was due to handle_unmatched_new_item() initially setting the status to GIT_DELTA_CONFLICTED but then overriding it later with GIT_DELTA_ADDED.

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.

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.

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.

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.

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.
