94fb4aad	2014-04-28T14:48:41	Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.
0fc8e1f6	2014-04-28T14:34:55	Lay groundwork for updating stat cache in diff This reorganized the diff OID calculation to make it easier to correctly update the stat cache during a diff once the flags to do so are enabled. This includes marking the path of a git_index_entry as const so we can make a "fake" git_index_entry with a "const char *" path and not get warnings. I was a little surprised at how unobtrusive this change was, but I think it's probably a good thing.
8ef4e11a	2014-04-28T14:16:26	Skip diff oid calc when size definitely changed When we think the stat cache in the index seems valid and the size or mode of a file has definitely changed, then don't bother trying to recalculate the OID of the workdir bits to confirm that it is modified - just accept that it is modified. This can result in files that show as modified with no actual diff, but the behavior actually appears to match Git on the command line. This also includes a minor optimization to not perform a submodule lookup on the ".git" directory itself.

c7f86efb	2014-04-26T18:04:43	zstream: grow based on used memory rather than allocated When deflating data, we might need to grow the buffer. Currently we add a guess on top of the currently-allocated buffer size. When we re-use the buffer, it already has some memory allocated; adding to that means that we always grow the buffer regardless of how much we need to use. Instead, increase on top of the currently-used size. This still leaves us with the allocated size of the largest object we compress, but it's a minor pain compared to unbounded growth. This fixes #2285.

a409acef	2014-04-24T11:59:50	Handle explicitly ignored dir slightly differently When considering status of untracked directories, if we find an explicitly ignored item, even if it is a directory, treat the parent as an IGNORED item. It was accidentally being treated as an EMPTY item because we were not looking into the ignored subdir.
bdc82e1c	2014-04-24T14:08:29	fetchhead: deal with quotes in branch names The current FETCH_HEAD parsing code assumes that a quote must end the branch name. Git however allows for quotes as part of a branch name, which causes us to consider the FETCH_HEAD file as invalid. Instead of searching for a single quote char, search for a quote char followed by SP, which is not a valid part of a ref name.

219c89d1	2014-04-23T16:28:45	Treat ignored, empty, and untracked dirs different In the iterator, distinguish between ignores and empty directories so that diff and status can ignore empty directories, but checkout and stash can treat them as untracked items.

37da3685	2014-04-22T21:51:54	Make checkout match diff for untracked/ignored dir When diff finds an untracked directory, it emulates Git behavior by looking inside the directory to see if there are any untracked items inside it. If there are only ignored items inside the dir, then diff considers it ignored, even if there is no direct ignore rule for it. Checkout was not copying this behavior - when it found an untracked directory, it just treated it as untracked. Unfortunately, when combined with GIT_CHECKOUT_REMOVE_UNTRACKED, this made is seem that checkout (and stash, which uses checkout) was removing ignored items when you had only asked it to remove untracked ones. This commit moves the logic for advancing past an untracked dir while scanning for non-ignored items into an iterator helper fn, and uses that for both diff and checkout.
e349ed50	2014-04-22T14:58:33	patch: emit binary patches (optionally)
24d17de2	2014-04-02T12:07:27	Make stash and checkout ignore contained repos To emulate git, stash should not remove untracked git repositories inside the parent repo, and checkout's REMOVE_UNTRACKED should also skip over these items. `git stash` actually prints a warning message for these items. That should be possible with a checkout notify callback if you wanted to, although it would require a bit of extra logic as things are at the moment.

8d09efa2	2014-04-22T12:33:27	Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.
12e422a0	2014-04-21T16:08:05	Some doc and examples/diff.c changes I was playing with "git diff-index" and wanted to be able to emulate that behavior a little more closely with the diff example. Also, I wanted to play with running `git_diff_tree_to_workdir` directly even though core Git doesn't exactly have the equivalent, so I added a command line option for that and tweaked some other things in the example code. This changes a minor output thing in that the "raw" print helper function will no longer add ellipses (...) if the OID is not actually abbreviated.
bc0a6198	2014-04-19T15:52:58	transports: allow the creds callback to say it doesn't exist Allow the credentials callback to return GIT_PASSTHROUGH to make the transports code behave as though none was set. This should make it easier for bindings to behave closer to the C code when there is no credentials callback set at their level.
2efd7df6	2014-04-19T15:34:12	remote: provide read access to the callback structure This should make it easier for bindings to dynamically override their own callbacks.

ac16bd0a	2014-04-18T15:45:59	Minor fixes Only apply LEADING_DIR pattern munging to patterns in ignore and attribute files, not to pathspecs used to select files to operate on. Also, allow internal macro definitions to be evaluated before loading all external ones (important so that external ones can make use of internal `binary` definition).
916fcbd6	2014-04-18T14:42:40	Fix ignore difference from git with trailing /* Ignore patterns that ended with a trailing '/' were still needing to match against another actual '/' character in the full path. This is not the same behavior as core Git. Instead, we strip a trailing '/' off of any patterns that were matching and just take it to imply the FNM_LEADING_DIR behavior.
e3a2a04c	2014-04-18T14:29:58	Preload attribute files that may contain macros There was a latent bug where files that use macro definitions could be parsed before the macro definitions were loaded. Because of attribute file caching, preloading files that are going to be used doesn't add a significant amount of overhead, so let's always preload any files that could contain macros before we assemble the actual vector of files to scan for attributes.
a622ff17	2014-04-18T20:05:28	Only zero sensitive information on destruction (and memory actually allocated by us)
6a0956e5	2014-04-18T10:32:35	Pop ignore only if whole relative path matches When traversing the directory structure, the iterator pushes and pops ignore files using a vector. Some directories don't have ignore files, so it uses a path comparison to decide when it is right to actually pop the last ignore file. This was only comparing directory suffixes, though, so a subdirectory with the same name as a parent could result in the parent's .gitignore being popped off the list ignores too early. This changes the logic to compare the entire relative path of the ignore file.

bd270b70	2014-04-18T17:08:10	cred: tighten username rules The ssh-specific credentials allow the username to be missing. The idea being that the ssh transport will then use the username provided in the url, if it's available. There are two main issues with this. The credential callback already knows what username was provided by the url and needs to figure out whether it wants to ask the user for it or it can reuse it, so passing NULL as the username means the credential callback is suspicious. The username provided in the url is not in fact used by the transport. The only time it even considers it is for the user/pass credential, which asserts the existence of a username in its constructor. For the ssh-specific ones, it passes in the username stored in the credential, which is NULL. The libssh2 macro we use runs strlen() against this value (which is no different from what we would be doing ourselves), so we then crash. As the documentation doesn't suggest to leave out the username, assert the need for a username in the code, which removes this buggy behavior and removes implicit state. git_cred_has_username() becomes a blacklist of credential types that do not have a username. The only one at the moment is the 'default' one, which is meant to call up some Microsoft magic.

823c0e9c	2014-04-17T11:53:13	Fix broken logic for attr cache invalidation The checks to see if files were out of date in the attibute cache was wrong because the cache-breaker data wasn't getting stored correctly. Additionally, when the cache-breaker triggered, the old file data was being leaked.
e6e8530a	2014-04-14T12:31:17	Lock attribute file while reparsing data I don't love this approach, but achieving thread-safety for attribute and ignore data while reloading files would require a larger rewrite in order to avoid this. If an attribute or ignore file is out of date, this holds a lock on the file while we are reloading the data so that another thread won't try to reload the data at the same time.
ea642d61	2014-04-14T12:29:27	Fix race checking for existing index items In the threading tests, I was still seeing a race condition where the same item could end up being inserted multiple times into the index. Preserving the sorted-ness of the index outside of the `index_insert` call fixes the issue.
2e9d813b	2014-04-11T12:12:47	Fix tests with new attr cache code
7d490872	2014-04-10T22:31:01	Attribute file cache refactor This is a big refactoring of the attribute file cache to be a bit simpler which in turn makes it easier to enforce a lock around any updates to the cache so that it can be used in a threaded env. Tons of changes to the attributes and ignores code.
1fa17b5c	2014-03-14T22:01:30	Minor tree cache speedups While I was looking at the conflict cleanup code, I looked over at the tree cache code, since we clear the tree cache for each entry that gets removed and there is some redundancy there. I made some small tweaks to avoid extra calls to strchr and strlen in a few circumstances.
aba6b5ed	2014-03-14T21:59:26	Fix leak in git_index_conflict_cleanup I introduced a leak into conflict cleanup by removing items from inside the git_vector_remove_matching call. This simplifies the code to just use one common way for the two conflict cleanup APIs. When an index has an active snapshot, removing an item can cause an error (inserting into the deferred deletion vector), so I made the git_index_conflict_cleanup API return an error code. I felt like this wasn't so bad since it is just like the other APIs. I fixed up a couple of comments while I was changing the header.
cef170ab	2014-03-14T16:45:46	Fix leak when using push and pop with ignores The iterator pushes and pops ignores incrementally onto a list as it traverses the directory structure so that it doesn't have to constantly recheck which ignore files apply. With the new ref counting, it wasn't decrementing the refcount on the ignores that it removed from the vector.
b8777615	2014-03-14T15:37:42	Fix refcount issues with mutex protected ignores Some ignore files were not being freed from the cache.

52bb0476	2014-03-14T13:53:15	Clean up index snapshot function naming Clear up some of the various "find" functions and the snapshot API naming to be things I like more.
8a2834d3	2014-03-14T13:20:51	Index locking and entry allocation changes This makes the lock management on the index a little bit broader, having a number of routines hold the lock across looking up the item to be modified and actually making the modification. Still not true thread safety, but more pure index modifications are now safe which allows the simple cases (such as starting up a diff while index modifications are underway) safe enough to get the snapshot without hitting allocation problems. As part of this, I simplified the allocation of index entries to use a flex array and just put the path at the end of the index entry. This makes every entry self-contained and makes it a little easier to feel sure that pointers to strings aren't being accidentally copied and freed while other references are still being held.
40ed4990	2014-02-11T14:45:37	Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.
3b4c401a	2014-02-10T13:20:08	Decouple index iterator sort from index This makes the index iterator honor the GIT_ITERATOR_IGNORE_CASE and GIT_ITERATOR_DONT_IGNORE_CASE flags without modifying the index data itself. To take advantage of this, I had to export a number of the internal index entry comparison functions. I also wrote some new tests to exercise the capability.
dac16048	2014-02-08T16:42:26	Add mutex around index entries changes This surrounds any function that mutates the entries vector with a mutex so it can be safely snapshotted.

27e54bcf	2014-02-07T14:17:19	Add public diff print helpers The usefulness of these helpers came up for me while debugging some of the iterator changes that I was making, so since they have also been requested (albeit indirectly) I thought I'd include them.
3dbee456	2014-02-07T14:10:35	Some index internals refactoring Again, laying groundwork for some index iterator changes, this contains a bunch of code refactorings for index internals that should make it easier down the line to add locking around index modifications. Also this removes the redundant prefix_position function and fixes some potential memory leaks.

a9528b8f	2014-04-14T15:59:48	Fix core.excludesfile named .gitignore Ignore rules with slashes in them are matched using FNM_PATHNAME and use the path to the .gitignore file from the root of the repository along with the path fragment (including slashes) in the ignore file itself. Unfortunately, the relative path to the .gitignore file was being applied to the global core.excludesfile if that was also named ".gitignore". This fixes that with more precise matching and includes test for ignore rules with leading slashes (which were the primary example of this being broken in the real world). This also backports an improvement to the file context logic from the threadsafe-iterators branch where we don't rely on mutating the key of the attribute file name to generate the context path.

8f7bc646	2014-04-10T16:33:39	Fix bug popping ignore files during wd iteration There were a couple bugs in popping ignore files during iteration that could result in incorrect decisions be made and thus ignore files below the root either not being loaded correctly or not being popped at the right time. One bug was an off-by-one in comparing the path of the gitignore file with the path being exited during iteration. The second bug was not correctly truncating the path being tracked during traversal if there were no ignores on the list (i.e. when you have no .gitignore at the root, but do have some in contained directories).

Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.

Lay groundwork for updating stat cache in diff This reorganized the diff OID calculation to make it easier to correctly update the stat cache during a diff once the flags to do so are enabled. This includes marking the path of a git_index_entry as const so we can make a "fake" git_index_entry with a "const char *" path and not get warnings. I was a little surprised at how unobtrusive this change was, but I think it's probably a good thing.

zstream: grow based on used memory rather than allocated When deflating data, we might need to grow the buffer. Currently we add a guess on top of the currently-allocated buffer size. When we re-use the buffer, it already has some memory allocated; adding to that means that we always grow the buffer regardless of how much we need to use. Instead, increase on top of the currently-used size. This still leaves us with the allocated size of the largest object we compress, but it's a minor pain compared to unbounded growth. This fixes #2285.

Handle explicitly ignored dir slightly differently When considering status of untracked directories, if we find an explicitly ignored item, even if it is a directory, treat the parent as an IGNORED item. It was accidentally being treated as an EMPTY item because we were not looking into the ignored subdir.

fetchhead: deal with quotes in branch names The current FETCH_HEAD parsing code assumes that a quote must end the branch name. Git however allows for quotes as part of a branch name, which causes us to consider the FETCH_HEAD file as invalid. Instead of searching for a single quote char, search for a quote char followed by SP, which is not a valid part of a ref name.

Make checkout match diff for untracked/ignored dir When diff finds an untracked directory, it emulates Git behavior by looking inside the directory to see if there are any untracked items inside it. If there are only ignored items inside the dir, then diff considers it ignored, even if there is no direct ignore rule for it. Checkout was not copying this behavior - when it found an untracked directory, it just treated it as untracked. Unfortunately, when combined with GIT_CHECKOUT_REMOVE_UNTRACKED, this made is seem that checkout (and stash, which uses checkout) was removing ignored items when you had only asked it to remove untracked ones. This commit moves the logic for advancing past an untracked dir while scanning for non-ignored items into an iterator helper fn, and uses that for both diff and checkout.

Make stash and checkout ignore contained repos To emulate git, stash should not remove untracked git repositories inside the parent repo, and checkout's REMOVE_UNTRACKED should also skip over these items. `git stash` actually prints a warning message for these items. That should be possible with a checkout notify callback if you wanted to, although it would require a bit of extra logic as things are at the moment.

Use git_diff_get_stats in example/diff + refactor This takes the `--stat` and related example options in the example diff.c program and converts them to use the `git_diff_get_stats` API which nicely formats stats for you. I went to add bar-graph scaling to the stats formatter and noticed that the `git_diff_stats` structure was holding on to all of the `git_patch` objects. Unfortunately, each of these objects keeps the full text of the diff in memory, so this is very expensive. I ended up modifying `git_diff_stats` to keep just the data that it needs to keep and allowed it to release the patches. Then, I added width scaling to the output on top of that. In making the diff example program match 'git diff' output, I ended up removing an newline from the sumamry output which I then had to compensate for in the email formatting to match the expectations. Lastly, I went through and refactored the tests to use a couple of helper functions and reduce the overall amount of code there.

Some doc and examples/diff.c changes I was playing with "git diff-index" and wanted to be able to emulate that behavior a little more closely with the diff example. Also, I wanted to play with running `git_diff_tree_to_workdir` directly even though core Git doesn't exactly have the equivalent, so I added a command line option for that and tweaked some other things in the example code. This changes a minor output thing in that the "raw" print helper function will no longer add ellipses (...) if the OID is not actually abbreviated.

Fix ignore difference from git with trailing /* Ignore patterns that ended with a trailing '/*' were still needing to match against another actual '/' character in the full path.

Preload attribute files that may contain macros There was a latent bug where files that use macro definitions could be parsed before the macro definitions were loaded. Because of attribute file caching, preloading files that are going to be used doesn't add a significant amount of overhead, so let's always preload any files that could contain macros before we assemble the actual vector of files to scan for attributes.

Pop ignore only if whole relative path matches When traversing the directory structure, the iterator pushes and pops ignore files using a vector. Some directories don't have ignore files, so it uses a path comparison to decide when it is right to actually pop the last ignore file. This was only comparing directory suffixes, though, so a subdirectory with the same name as a parent could result in the parent's .gitignore being popped off the list ignores too early. This changes the logic to compare the entire relative path of the ignore file.

cred: tighten username rules The ssh-specific credentials allow the username to be missing. The idea being that the ssh transport will then use the username provided in the url, if it's available. There are two main issues with this. The credential callback already knows what username was provided by the url and needs to figure out whether it wants to ask the user for it or it can reuse it, so passing NULL as the username means the credential callback is suspicious. The username provided in the url is not in fact used by the transport. The only time it even considers it is for the user/pass credential, which asserts the existence of a username in its constructor. For the ssh-specific ones, it passes in the username stored in the credential, which is NULL. The libssh2 macro we use runs strlen() against this value (which is no different from what we would be doing ourselves), so we then crash. As the documentation doesn't suggest to leave out the username, assert the need for a username in the code, which removes this buggy behavior and removes implicit state. git_cred_has_username() becomes a blacklist of credential types that do not have a username. The only one at the moment is the 'default' one, which is meant to call up some Microsoft magic.

Lock attribute file while reparsing data I don't love this approach, but achieving thread-safety for attribute and ignore data while reloading files would require a larger rewrite in order to avoid this. If an attribute or ignore file is out of date, this holds a lock on the file while we are reloading the data so that another thread won't try to reload the data at the same time.

Minor tree cache speedups While I was looking at the conflict cleanup code, I looked over at the tree cache code, since we clear the tree cache for each entry that gets removed and there is some redundancy there.

Fix leak in git_index_conflict_cleanup I introduced a leak into conflict cleanup by removing items from inside the git_vector_remove_matching call. This simplifies the code to just use one common way for the two conflict cleanup APIs. When an index has an active snapshot, removing an item can cause an error (inserting into the deferred deletion vector), so I made the git_index_conflict_cleanup API return an error code. I felt like this wasn't so bad since it is just like the other APIs. I fixed up a couple of comments while I was changing the header.

Fix leak when using push and pop with ignores The iterator pushes and pops ignores incrementally onto a list as it traverses the directory structure so that it doesn't have to constantly recheck which ignore files apply. With the new ref counting, it wasn't decrementing the refcount on the ignores that it removed from the vector.

Index locking and entry allocation changes This makes the lock management on the index a little bit broader, having a number of routines hold the lock across looking up the item to be modified and actually making the modification. Still not true thread safety, but more pure index modifications are now safe which allows the simple cases (such as starting up a diff while index modifications are underway) safe enough to get the snapshot without hitting allocation problems. As part of this, I simplified the allocation of index entries to use a flex array and just put the path at the end of the index entry. This makes every entry self-contained and makes it a little easier to feel sure that pointers to strings aren't being accidentally copied and freed while other references are still being held.

Fix core.excludesfile named .gitignore Ignore rules with slashes in them are matched using FNM_PATHNAME and use the path to the .gitignore file from the root of the repository along with the path fragment (including slashes) in the ignore file itself. Unfortunately, the relative path to the .gitignore file was being applied to the global core.excludesfile if that was also named ".gitignore". This fixes that with more precise matching and includes test for ignore rules with leading slashes (which were the primary example of this being broken in the real world). This also backports an improvement to the file context logic from the threadsafe-iterators branch where we don't rely on mutating the key of the attribute file name to generate the context path.

Fix bug popping ignore files during wd iteration There were a couple bugs in popping ignore files during iteration that could result in incorrect decisions be made and thus ignore files below the root either not being loaded correctly or not being popped at the right time. One bug was an off-by-one in comparing the path of the gitignore file with the path being exited during iteration. The second bug was not correctly truncating the path being tracked during traversal if there were no ignores on the list (i.e. when you have no .gitignore at the root, but do have some in contained directories).
