75d0b81a	2015-07-07T16:46:48	xdiff: upgrade to core git 2.4.5 Upgrade xdiff to version used in core git 2.4.5 (0df0541). Corrects an issue where an LF is added at EOF while applying an unrelated change (ba31180), cleans up some unused code (be89977 and e5b0662), and provides an improved callback to avoid leaking internal (to xdiff) structures (467d348). This also adds some additional functionality that we do not yet take advantage of, namely the ability to ignore changes whose lines are all blank (36617af).

e0af3cb3	2015-07-01T21:15:06	submodule: correctly delimit the keys to use for lookup The regex we use to look at the gitmodules file does not correctly delimit the name of submodule which we want to look up and puts '.*' straight after the name, maching on any submodule which has the seeked submodule as a prefix of its name. Add the missing '\.' in the regex so we want a full stop to exist both before and after the submodule name.

9126ccac	2015-06-30T16:48:47	Fix #3093 - remove declaration of unused function git_fetch__download_pack Function was added in commit 2c982daa2eec64b80c7940bfe1142295bd72edd8 on October 5, 2011, and removed in commit 41fb1ca0ec51ad1d2a14b911aab3215e42965d1b on October 29, 2012. Given the length of time it's gone unused, it's safe to remove now.

3d9ef2dc	2015-06-26T16:45:42	Revert "object: correct the expected ID size in prefix lookup" This reverts commit 969d4b703c910a8fd045baafbcd243b4c9825316. This was a fluke from Coverity. The length to all the APIs in the library is supposed to be passed in as nibbles, not bytes. Passing it as bytes would prevent us from parsing uneven-sized SHA1 strings. Also, the rest of the library was still using nibbles (including revparse and the odb_prefix APIs), so this change was seriously breaking things in unexpected ways. ^^

23aa7c90	2015-06-25T13:40:38	remote: insert refspecs with no rhs in FETCH_HEAD When a refspec contains no rhs and thus won't cause an explicit update, we skip all the logic, but that means that we don't update FETCH_HEAD with it, which is what the implicit rhs is. Add another bit of logic which puts those remote heads in the list of updates so we put them into FETCH_HEAD.

caab22c0	2015-06-23T15:41:58	buffer: don't allow growing borrowed buffers When we don't own a buffer (asize=0) we currently allow the usage of grow to copy the memory into a buffer we do own. This muddles the meaning of grow, and lets us be a bit cavalier with ownership semantics. Don't allow this any more. Usage of grow should be restricted to buffers which we know own their own memory. If unsure, we must not attempt to modify it.

54077091	2015-06-24T12:06:41	diff: determine DIFFABLE-ness for binaries Always set `GIT_DIFF_PATCH_DIFFABLE` for all files, regardless of binary-ness, so that the binary callback is invoked to either show the binary contents, or just print the standard "Binary files differ" message. We may need to do deeper inspection for binary files where we have avoided loading the contents into a file map.
58ca8c7e	2015-06-24T17:27:16	SecureTransport: use the curl stream if available If the libcurl stream is available, use that as the underlying stream instead of the socket stream. This allows us to set a proxy for HTTPS connections.
8443f492	2015-06-11T16:57:04	curl: remove the encrypted param to the constructor We do not want libcurl to perform the TLS negotiation for us, so we don't need to pass this option.
f97d5d09	2015-06-11T16:54:48	http: ask for the curl stream for non-encrypted connections The TLS streams talk over the curl stream themselves, so we don't need to ask for it explicitly. Do so in the case of the non-encrypted one so we can still make use proxies in that case.
e247649d	2015-06-11T16:50:44	openssl: use the curl stream if available When linking against libcurl, use it as the underlying transport instead of straight sockets. We can't quite just give over the file descriptor, as curl puts it into non-blocking mode, so we build a custom BIO so OpenSSL sends the data through our stream, be it the socket or curl streams.
cdee630f	2015-06-09T19:07:58	curl: extract certificate information The information is exposed by curl for some crypto libraries in the form of name:content strings. We can't do much more than return this information.
8762d721	2015-06-07T14:51:10	http: set the proxy if the stream supports it Of the built-in ones, only cURL support it, but there's no reason a user-provided stream wouldn't support it.
1376e784	2015-06-07T14:42:13	stream: add support for setting a proxy If the stream claims to support this feature, we can let the transport set the proxy. We also set HTTPPROXYTUNNEL option so curl can create a tunnel through the proxy which lets us create our own TLS session (if needed).
8dea1c21	2015-06-05T11:02:11	Implement a curl stream cURL has a mode in which it acts a lot like our streams, providing send and recv functions and taking care of the TLS and proxy setup for us. Implement a new stream which uses libcurl instead of raw sockets or the TLS libraries directly. This version does not support reporting certificates or proxies yet.

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.

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.

c4e3a3db	2015-05-09T11:22:57	submodule: handle writing out all enum values for settings We currently do not handle those enum values which require us to set "true" or unset variables in all cases. Use a common function which does understand this by looking at our mapping directly.
15c38103	2015-05-09T11:22:27	config: provide a function to reverse-lookup mapped cvars
961861fa	2015-05-05T09:25:17	submodule: get rid of `_save()` We no longer have any setters which affect an instance, so `git_submodule_save()` is no longer relevant.
d6073b30	2015-05-05T09:22:35	submodule: make `_set_url()` affect the configuration With this one, we can get rid of the edit_and_save test.
486ba4cd	2015-05-05T09:13:52	submodule: make `_set_branch()` affect the configuration
4e636423	2015-05-05T09:01:20	submodule: make `_set_update_fetch_recurse_submodules()` affect the config Similarly to the other ones. In this test we copy over testing `RECURSE_YES` which shows an error in our handling of the `YES` variant which we may have to port to the rest.
e8a39f8e	2015-05-05T08:35:29	submodule: make `_set_update()` affect the configuration Moving on with the removal of runtime-changing variables, the update setting for a remote is whatever it was when it was looked up.
2278637c	2015-05-05T06:14:40	submodule: correct detection of existing submodules During the cache deletion, the check for whether we consider a submodule to exist got changed regarding submodules which are in the worktree but not configured. Instead of checking for the url field to be populated, check the location where we've found it.
d769a3fd	2015-05-05T06:03:21	submodule: bring back finding by path During the removal of the cache, we also removed the ability to use `_lookup()` to search by path rather than name. Bring this logic back.
c6f489c9	2015-05-04T17:29:12	submodule: add an ignore option to status This lets us specify in the status call which ignore rules we want to use (optionally falling back to whatever the submodule has in its configuration). This removes one of the reasons for having `_set_ignore()` set the value in-memory. We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.
64bbd47a	2015-05-04T17:09:21	submodule: don't let status change an existing instance As submodules are becomes more like values, we should not let a status check to update its properties. Instead of taking a submodule, have status take a repo and submodule name.
5a9fc6c8	2015-05-04T16:22:56	submodule: make set_ignore() affect the configuration Instead of affecting a particular instance, make it change the configuration.
dfda2f68	2015-04-27T19:27:29	submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.
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.)

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.

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.

xdiff: upgrade to core git 2.4.5 Upgrade xdiff to version used in core git 2.4.5 (0df0541). Corrects an issue where an LF is added at EOF while applying an unrelated change (ba31180), cleans up some unused code (be89977 and e5b0662), and provides an improved callback to avoid leaking internal (to xdiff) structures (467d348). This also adds some additional functionality that we do not yet take advantage of, namely the ability to ignore changes whose lines are all blank (36617af).

submodule: correctly delimit the keys to use for lookup The regex we use to look at the gitmodules file does not correctly delimit the name of submodule which we want to look up and puts '.*' straight after the name, maching on any submodule which has the seeked submodule as a prefix of its name. Add the missing '\.' in the regex so we want a full stop to exist both before and after the submodule name.

Fix #3093 - remove declaration of unused function git_fetch__download_pack Function was added in commit 2c982daa2eec64b80c7940bfe1142295bd72edd8 on October 5, 2011, and removed in commit 41fb1ca0ec51ad1d2a14b911aab3215e42965d1b on October 29, 2012. Given the length of time it's gone unused, it's safe to remove now.

Revert "object: correct the expected ID size in prefix lookup" This reverts commit 969d4b703c910a8fd045baafbcd243b4c9825316. This was a fluke from Coverity. The length to all the APIs in the library is supposed to be passed in as nibbles, not bytes. Passing it as bytes would prevent us from parsing uneven-sized SHA1 strings. Also, the rest of the library was still using nibbles (including revparse and the odb_prefix APIs), so this change was seriously breaking things in unexpected ways. ^^

This muddles the meaning of grow, and lets us be a bit cavalier with ownership semantics. Don't allow this any more. Usage of grow should be restricted to buffers which we know own their own memory. If unsure, we must not attempt to modify it.

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.

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.

We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.

submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

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.
