Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Carlos Martín Nieto 86d5810b 2014-05-06T16:20:14 pack: remove misleading comment
Carlos Martín Nieto e6d10c58 2014-05-08T16:24:54 pack: make sure not to leak the dep chain
Carlos Martín Nieto 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.
Carlos Martín Nieto 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.
Vicent Marti 4df53a64 2014-05-08T23:16:21 Merge pull request #2335 from libgit2/cmn/indexer-vector-handling indexer: avoid memory moves
Carlos Martín Nieto 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.
Russell Belfer 5ebe18b7 2014-05-08T13:29:09 Merge pull request #2332 from libgit2/peff/iconv iconv debugging aids
Jeff King 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.
Jeff King 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.

Russell Belfer 10511000 2014-05-06T14:03:58 Merge pull request #2324 from libgit2/cmn/file-in-objects-dir odb: ignore files in the objects dir
Anurag Gupta 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.
Carlos Martín Nieto 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.
Anurag Gupta 001befcd 2014-05-06T12:16:24 Fix the issues in git__on_shutdown
Carlos Martín Nieto ee311907 2014-05-05T16:04:14 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.

Vicent Marti 272b462d 2014-05-02T09:50:15 Merge pull request #2308 from libgit2/rb/diff-update-index-stat-cache Reduce excessive OID calculation for diff and stat
Russell Belfer 9862ef8e 2014-05-02T09:42:07 Merge pull request #2310 from libgit2/cmn/commit-create-safe commit: safer commit creation with reference update
Russell Belfer 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.
Russell Belfer 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.
Russell Belfer 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.
Russell Belfer 99dfa470 2014-05-01T15:12:12 Some further sandboxing cleanups to tests Trying to find other issues where tests may not clean up quite properly when they are through...
Russell Belfer 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.
Russell Belfer 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.
Russell Belfer 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).
Russell Belfer 9c8ed499 2014-04-29T15:05:58 Remove trace / add git_diff_perfdata struct + api
Russell Belfer 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.
Russell Belfer 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.
Russell Belfer 225aab5d 2014-04-28T16:47:39 Don't use trace if GIT_TRACE not defined
Russell Belfer 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.

Carlos Martín Nieto 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.

Carlos Martín Nieto 38d338b2 2014-04-26T18:15:39 pack-objects: always write out the status in write_one() Make sure we set the output parameter to a value.
Carlos Martín Nieto 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.

Russell Belfer 6b833e3a 2014-04-24T15:40:50 Improve docs for status rename detection limits and make tests empty on platforms without iconv support.
Russell Belfer 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.
Russell Belfer 2334e3d8 2014-04-24T14:46:59 Test decomposed unicode renames work as expected
Russell Belfer 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.
Vicent Marti 87c9b741 2014-04-24T05:24:46 Merge pull request #2295 from libgit2/cmn/fetchhead-quote fetchhead: deal with quotes in branch names
Carlos Martín Nieto 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.

Russell Belfer 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.

Russell Belfer 3c1aa4c1 2014-04-22T15:23:39 Failing test for stashing a buried ignored file
Russell Belfer 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.
Russell Belfer e60883c8 2014-04-22T12:59:31 Replace math fns with simpler integer math
Russell Belfer 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.
Russell Belfer 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.
