15bcced2	2014-05-11T05:31:22	pack: use stack allocation for smaller delta chains This avoid allocating the array on the heap for relatively small chains. The expected performance increase is sadly not really noticeable.
a3ffbf23	2014-05-11T03:50:34	pack: expose a cached delta base directly Instead of going through a special entry in the chain, let's pass it as an output parameter.

9dbd150f	2014-05-09T09:36:09	pack: simplify delta chain code The switch makes the loop somewhat unwieldy. Let's assume it's fine and perform the check when we're accessing the data. This makes our code look a lot more like git's.
2acdf4b8	2014-05-06T19:20:33	pack: unpack using a loop We currently make use of recursive function calls to unpack an object, resolving the deltas as we come back down the chain. This means that we have unbounded stack growth as we look up objects in a pack. This is now done in two steps: first we figure out what the dependency chain is by looking up the delta bases until we reach a non-delta object, pushing the information we need onto a stack and then we pop from that stack and apply the deltas until there are no more left. This version of the code does not make use of the delta base cache so it is slower than what's in the mainline. A later commit will reintroduce it.
ae081739	2014-05-06T21:21:04	pack: do not repeat the same error message four times Repeating this error message makes it harder to find out where we actually are finding the error, and they don't really describe what we're trying to do.
86d5810b	2014-05-06T16:20:14	pack: remove misleading comment
b2559f47	2014-05-08T17:14:59	pack: preallocate a 64-element chain Dependency chains are often large and require a few reallocations. Allocate a 64-element chain before doing anything else to avoid allocations during the loop. This value comes from the stack-allocated one git uses. We still allocate this on the heap, but it does help performance a little bit.
e6d10c58	2014-05-08T16:24:54	pack: make sure not to leak the dep chain
a332e91c	2014-05-06T23:37:28	pack: use a cache for delta bases when unpacking Bring back the use of the delta base cache for unpacking objects. When generating the delta chain, we stop when we find a delta base in the pack's cache and use that as the starting point.

43a04135	2014-05-08T13:52:46	Pass unconverted data when iconv doesn't like it When using Iconv to convert unicode data and iconv doesn't like the source data (because it thinks that it's not actual UTF-8), instead of stopping the operation, just use the unconverted data. This will generally do the right thing on the filesystem, since that is the source of the non-UTF-8 path data anyhow. This adds some tests for creating and looking up branches with messy Unicode names. Also, this takes the helper function that was previously internal to `git_repository_init` and makes it into `git_path_does_fs_decompose_unicode` which is a useful in tests to understand what the expected results should be.
2dde1e0c	2014-05-08T22:31:59	indexer: avoid memory moves Our vector does a move of the rest of the array when we remove an item. Doing this repeatedly can be expensive, and we do this a lot in the indexer. Instead, set the value to NULL and skip those entries. perf reported around 30% of `index-pack` time was going into memmove. With this change, that goes away and we spent most of the time hashing and inflating data.
45c53eb6	2014-05-08T10:46:04	Use unsigned type for APIs with opt flag mask
1e4976cb	2014-05-08T10:17:14	Be more careful with user-supplied buffers This adds in missing calls to `git_buf_sanitize` and fixes a number of places where `git_buf` APIs could inadvertently write NUL terminator bytes into invalid buffers. This also changes the behavior of `git_buf_sanitize` to NUL terminate a buffer if it can and of `git_buf_shorten` to do nothing if it can. Adds tests of filtering code with zeroed (i.e. unsanitized) buffer which was previously triggering a segfault.
ac99d86b	2014-05-07T11:34:32	repository: introduce a convenience config snapshot method Accessing the repository's config and immediately taking a snapshot of it is a common operation, so let's provide a convenience function for it.

5269008c	2014-05-06T16:01:49	Add filter options and ALLOW_UNSAFE Diff and status do not want core.safecrlf to actually raise an error regardless of the setting, so this extends the filter API with an additional options flags parameter and adds a flag so that filters can be applied with GIT_FILTER_OPT_ALLOW_UNSAFE, indicating that unsafe filter application should be downgraded from a failure to a warning.
10511000	2014-05-06T14:03:58	Merge pull request #2324 from libgit2/cmn/file-in-objects-dir odb: ignore files in the objects dir
0bf5430d	2014-05-06T13:33:47	Fix the issues in git_shutdown 1) Call to git_shutdown results in setting git__n_shutdown_callbacks to -1. Next call to git__on_shutdown results in ABW (Array Bound Write) for array git__shutdown_callbacks. In the current Implementation, git_atomic_dec is called git__n_shutdown_callbacks + 1 times. I have modified it to a for loop so that it is more readable. It would not set git__n_shutdown_callbacks to a negative number and reset the elements of git__shutdown_callbacks to NULL. 2) In function git_sysdir_get, shutdown function is registered only if git_sysdir__dirs_shutdown_set is set to 0. However, after this variable is set to 1, it is never reset to 0. If git_sysdir_global_init is called again from synchronized_threads_init it does not register shutdown function for this subsystem.
f554611a	2014-05-06T12:41:26	Improve checks for ignore containment The diff code was using an "ignored_prefix" directory to track if a parent directory was ignored that contained untracked files alongside tracked files. Unfortunately, when negative ignore rules were used for directories inside ignored parents, the wrong rules were applied to untracked files inside the negatively ignored child directories. This commit moves the logic for ignore containment into the workdir iterator (which is a better place for it), so the ignored-ness of a directory is contained in the frame stack during traversal. This allows a child directory to override with a negative ignore and yet still restore the ignored state of the parent when we traverse out of the child. Along with this, there are some problems with "directory only" ignore rules on container directories. Given "a/*" and "!a/b/c/" (where the second rule is a directory rule but the first rule is just a generic prefix rule), then the directory only constraint was having "a/b/c/d/file" match the first rule and not the second. This was fixed by having ignore directory-only rules test a rule against the prefix of a file with LEADINGDIR enabled. Lastly, spot checks for ignores using `git_ignore_path_is_ignored` were tested from the top directory down to the bottom to deal with the containment problem, but this is wrong. We have to test bottom to top so that negative subdirectory rules will be checked before parent ignore rules. This does change the behavior of some existing tests, but it seems only to bring us more in line with core Git, so I think those changes are acceptable.
6e9afb97	2014-05-06T21:14:58	object: fix a brace The brace in the check for peel's return was surrounding the wrong thing, which made 'error' be set to 1 when there was an error instead of the error code.

7a2e56a3	2014-04-29T14:30:15	Get rid of redundant git_diff_options_init fn Since git_diff_init_options was introduced, remove this old fn.
b23b112d	2014-04-29T11:29:49	Add payloads, bitmaps to trace API This is a proposed adjustment to the trace APIs. This makes the trace levels into a bitmask so that they can be selectively enabled and adds a callback-level payload, plus a message-level payload. This makes it easier for me to a GIT_TRACE_PERF callbacks that are simply bypassed if the PERF level is not set.
cd424ad5	2014-04-28T16:39:53	Add GIT_STATUS_OPT_UPDATE_INDEX and use trace API This adds an option to refresh the stat cache while generating status. It also rips out the GIT_PERF stuff I had an makes use of the trace API to keep statistics about what happens during diff.
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.
0f603132	2014-05-01T14:47:33	Improve handling of fake home directory There are a few tests that set up a fake home directory and a fake GLOBAL search path so that we can test things in global ignore or attribute or config files. This cleans up that code to work more robustly even if there is a test failure. This also fixes some valgrind warnings where scanning search paths for separators could end up doing a little bit of sketchy data access when coming to the end of search list.
bc91347b	2014-04-30T11:16:31	Fix remaining init_options inconsistencies There were a couple of "init_opts()" functions a few more cases of structure initialization that I somehow missed.
702efc89	2014-04-30T10:57:42	Make init_options fns use unsigned ints and macro Use an unsigned int for the version and add a helper macro so the code is simplified (and so the error message is a common string).
9c8ed499	2014-04-29T15:05:58	Remove trace / add git_diff_perfdata struct + api
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.

Make sure that we're moving history forward when we ask the library to update the reference for us by checking that the first parent of the new commit is the current value of the reference. We also make sure that the ref we're updating hasn't moved between the read and the write. Similarly, when amending a commit, make sure that the current tip of the branch is the commit we're amending.

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.
783555d8	2014-04-26T14:36:32	netops: catch the server not sending a certificate It's possible for an encrypted connection not have a certificate. In this case, SSL_get_verify_result() will return OK because no error happened (as it never even tried to validate anything). SSL_get_peer_certificate() will return NULL in this case so we need to catch that. On the upside, the current code would segfault in this situation instead of letting it through as a valid cert.
51d3f6f5	2014-04-26T14:16:42	netops: provide more specific error for cert failure Specify what we do not like about the certificate. In this case, we do not like the name.

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.

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.

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.

pack: simplify delta chain code The switch makes the loop somewhat unwieldy. Let's assume it's fine and perform the check when we're accessing the data. This makes our code look a lot more like git's.

pack: unpack using a loop We currently make use of recursive function calls to unpack an object, resolving the deltas as we come back down the chain. This means that we have unbounded stack growth as we look up objects in a pack. This is now done in two steps: first we figure out what the dependency chain is by looking up the delta bases until we reach a non-delta object, pushing the information we need onto a stack and then we pop from that stack and apply the deltas until there are no more left. This version of the code does not make use of the delta base cache so it is slower than what's in the mainline. A later commit will reintroduce it.

pack: preallocate a 64-element chain Dependency chains are often large and require a few reallocations. Allocate a 64-element chain before doing anything else to avoid allocations during the loop.

Pass unconverted data when iconv doesn't like it When using Iconv to convert unicode data and iconv doesn't like the source data (because it thinks that it's not actual UTF-8), instead of stopping the operation, just use the unconverted data. This will generally do the right thing on the filesystem, since that is the source of the non-UTF-8 path data anyhow. This adds some tests for creating and looking up branches with messy Unicode names. Also, this takes the helper function that was previously internal to `git_repository_init` and makes it into `git_path_does_fs_decompose_unicode` which is a useful in tests to understand what the expected results should be.

indexer: avoid memory moves Our vector does a move of the rest of the array when we remove an item. Doing this repeatedly can be expensive, and we do this a lot in the indexer. Instead, set the value to NULL and skip those entries. perf reported around 30% of `index-pack` time was going into memmove. With this change, that goes away and we spent most of the time hashing and inflating data.

Be more careful with user-supplied buffers This adds in missing calls to `git_buf_sanitize` and fixes a number of places where `git_buf` APIs could inadvertently write NUL terminator bytes into invalid buffers. This also changes the behavior of `git_buf_sanitize` to NUL terminate a buffer if it can and of `git_buf_shorten` to do nothing if it can. Adds tests of filtering code with zeroed (i.e. unsanitized) buffer which was previously triggering a segfault.

Fix the issues in git_shutdown 1) Call to git_shutdown results in setting git__n_shutdown_callbacks to -1. Next call to git__on_shutdown results in ABW (Array Bound Write) for array git__shutdown_callbacks. In the current Implementation, git_atomic_dec is called git__n_shutdown_callbacks + 1 times. I have modified it to a for loop so that it is more readable. It would not set git__n_shutdown_callbacks to a negative number and reset the elements of git__shutdown_callbacks to NULL. 2) In function git_sysdir_get, shutdown function is registered only if git_sysdir__dirs_shutdown_set is set to 0. However, after this variable is set to 1, it is never reset to 0. If git_sysdir_global_init is called again from synchronized_threads_init it does not register shutdown function for this subsystem.

Improve checks for ignore containment The diff code was using an "ignored_prefix" directory to track if a parent directory was ignored that contained untracked files alongside tracked files. Unfortunately, when negative ignore rules were used for directories inside ignored parents, the wrong rules were applied to untracked files inside the negatively ignored child directories. This commit moves the logic for ignore containment into the workdir iterator (which is a better place for it), so the ignored-ness of a directory is contained in the frame stack during traversal. This allows a child directory to override with a negative ignore and yet still restore the ignored state of the parent when we traverse out of the child. Along with this, there are some problems with "directory only" ignore rules on container directories. Given "a/*" and "!a/b/c/" (where the second rule is a directory rule but the first rule is just a generic prefix rule), then the directory only constraint was having "a/b/c/d/file" match the first rule and not the second. This was fixed by having ignore directory-only rules test a rule against the prefix of a file with LEADINGDIR enabled. Lastly, spot checks for ignores using `git_ignore_path_is_ignored` were tested from the top directory down to the bottom to deal with the containment problem, but this is wrong. We have to test bottom to top so that negative subdirectory rules will be checked before parent ignore rules. This does change the behavior of some existing tests, but it seems only to bring us more in line with core Git, so I think those changes are acceptable.

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.

This cleans up that code to work more robustly even if there is a test failure.

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.

commit: safer commit creation with reference update The current version of the commit creation and amend function are unsafe to use when passing the update_ref parameter, as they do not check that the reference at the moment of update points to what the user expects. Make sure that we're moving history forward when we ask the library to update the reference for us by checking that the first parent of the new commit is the current value of the reference. We also make sure that the ref we're updating hasn't moved between the read and the write. Similarly, when amending a commit, make sure that the current tip of the branch is the commit we're amending.

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.

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.

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.
