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.

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.

56ec2256	2014-05-08T01:06:38	examples: add a basic for-each-ref example This is quite close to running "git for-each-ref" except: 1. It does not take any formatting or selection options at all. 2. The output is not sorted. I wrote it to look at debugging some issues with ref iteration, but there's no reason it can't live on as an example command.
6bcb0987	2014-05-08T00:35:56	cmake: s/ICONV/Iconv/ in FIND_PACKAGE The cmake module we provide is in the file FindIconv.cmake, so we must match the case correctly. It happens to work in practice because we only turn on ICONV on Darwin, and people generally have case-insensitive filesystems there. Note that we only need to update the package name here. The package itself still sets the all-uppercase ICONV_FOUND flag, so we continue to use uppercase in the rest of cmake.

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.

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.

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.
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.

217c029b	2014-04-09T14:08:22	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.

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.

f608f3bb	2014-04-24T15:25:01	Test toggling core.precomposeunicode yields rename There is an interesting difference with core Git here, though. Because libgit2 will do rename detection with the working directory, in the last case where the HEAD and the working directory both have the decomposed data and the index has the composed data, we generate a single status record with two renames whereas Git will generate one rename (head to index) and one untracked file.

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.

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.

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: 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.

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.

cmake: s/ICONV/Iconv/ in FIND_PACKAGE The cmake module we provide is in the file FindIconv.cmake, so we must match the case correctly. It happens to work in practice because we only turn on ICONV on Darwin, and people generally have case-insensitive filesystems there. Note that we only need to update the package name here. The package itself still sets the all-uppercase ICONV_FOUND flag, so we continue to use uppercase in the rest of cmake.

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.

odb: ignore files in the objects dir We assume that everything under GIT_DIR/objects/ is a directory. This is not necessarily the case if some process left a stray file in there. Check beforehand if we do have a directory and ignore the entry otherwise.

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.

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.

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.

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.

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.

f608f3bb

2014-04-24T15:25:01

Test toggling core.precomposeunicode yields rename There is an interesting difference with core Git here, though. Because libgit2 will do rename detection with the working directory, in the last case where the HEAD and the working directory both have the decomposed data and the index has the composed data, we generate a single status record with two renames whereas Git will generate one rename (head to index) and one untracked file.

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.

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.

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.

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.

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.
