Most gmtime implementations return a NULL value when they encounter an error (and this behavior is specified by ANSI C and POSIX). FreeBSD's implementation, however, will simply leave the "struct tm" untouched. Let's also recognize this and convert it to a NULL (with this patch, t4212 should pass on FreeBSD).

2014-02-24test-lib: allow setting the index format versionLibravatar Thomas Gummerer1-0/+7
Allow adding a TEST_GIT_INDEX_VERSION variable to config.mak to set the index version with which the test suite should be run. If it isn't set, the default version given in the source code is used (currently version 3). To avoid breakages with index versions other than [23], also set the index version under which t2104 is run to 3. This test only tests functionality specific to version 2 and 3 of the index file and would fail if the test suite is run with any other version.

The values passed via -DMAJOR=, -DMINOR=, and -DPATCH= are used in FILEVERSION and PRODUCTVERSION statements, which expect up to four numeric values. These version numbers are intended for machine consumption. They are typically inspected by installers to decide whether a file to be installed is newer than one that exists on the system, but are not used for much else. We can be pretty certain that there are no tools that look at these version numbers, not even the installer of Git for Windows does. Therefore, to fix the syntax error, fill in only the first two numbers, which we are guaranteed to find in Git version numbers.

2013-12-30pack-objects: implement bitmap writingLibravatar Vicent Marti1-0/+1
This commit extends more the functionality of `pack-objects` by allowing it to write out a `.bitmap` index next to any written packs, together with the `.idx` index that currently gets written. If bitmap writing is enabled for a given repository (either by calling `pack-objects` with the `--write-bitmap-index` flag or by having `pack.writebitmaps` set to `true` in the config) and pack-objects is writing a packfile that would normally be indexed (i.e. not piping to stdout), we will attempt to write the corresponding bitmap index for the packfile. Bitmap index writing happens after the packfile and its index has been successfully written to disk (`finish_tmp_packfile`). The process is performed in several steps: 1. `bitmap_writer_set_checksum`: this call stores the partial checksum for the packfile being written; the checksum will be written in the resulting bitmap index to verify its integrity 2. `bitmap_writer_build_type_index`: this call uses the array of `struct object_entry` that has just been sorted when writing out the actual packfile index to disk to generate 4 type-index bitmaps (one for each object type). These bitmaps have their nth bit set if the given object is of the bitmap's type. E.g. the nth bit of the Commits bitmap will be 1 if the nth object in the packfile index is a commit. This is a very cheap operation because the bitmap writing code has access to the metadata stored in the `struct object_entry` array, and hence the real type for each object in the packfile. 3. `bitmap_writer_reuse_bitmaps`: if there exists an existing bitmap index for one of the packfiles we're trying to repack, this call will efficiently rebuild the existing bitmaps so they can be reused on the new index. All the existing bitmaps will be stored in a `reuse` hash table, and the commit selection phase will prioritize these when selecting, as they can be written directly to the new index without having to perform a revision walk to fill the bitmap. This can greatly speed up the repack of a repository that already has bitmaps. 4. `bitmap_writer_select_commits`: if bitmap writing is enabled for a given `pack-objects` run, the sequence of commits generated during the Counting Objects phase will be stored in an array. We then use that array to build up the list of selected commits. Writing a bitmap in the index for each object in the repository would be cost-prohibitive, so we use a simple heuristic to pick the commits that will be indexed with bitmaps. The current heuristics are a simplified version of JGit's original implementation. We select a higher density of commits depending on their age: the 100 most recent commits are always selected, after that we pick 1 commit of each 100, and the gap increases as the commits grow older. On top of that, we make sure that every single branch that has not been merged (all the tips that would be required from a clone) gets their own bitmap, and when selecting commits between a gap, we tend to prioritize the commit with the most parents. Do note that there is no right/wrong way to perform commit selection; different selection algorithms will result in different commits being selected, but there's no such thing as "missing a commit". The bitmap walker algorithm implemented in `prepare_bitmap_walk` is able to adapt to missing bitmaps by performing manual walks that complete the bitmap: the ideal selection algorithm, however, would select the commits that are more likely to be used as roots for a walk in the future (e.g. the tips of each branch, and so on) to ensure a bitmap for them is always available. 5. `bitmap_writer_build`: this is the computationally expensive part of bitmap generation. Based on the list of commits that were selected in the previous step, we perform several incremental walks to generate the bitmap for each commit. The walks begin from the oldest commit, and are built up incrementally for each branch. E.g. consider this dag where A, B, C, D, E, F are the selected commits, and a, b, c, e are a chunk of simplified history that will not receive bitmaps. A---a---B--b--C--c--D \ E--e--F We start by building the bitmap for A, using A as the root for a revision walk and marking all the objects that are reachable until the walk is over. Once this bitmap is stored, we reuse the bitmap walker to perform the walk for B, assuming that once we reach A again, the walk will be terminated because A has already been SEEN on the previous walk. This process is repeated for C, and D, but when we try to generate the bitmaps for E, we can reuse neither the current walk nor the bitmap we have generated so far. What we do now is resetting both the walk and clearing the bitmap, and performing the walk from scratch using E as the origin. This new walk, however, does not need to be completed. Once we hit B, we can lookup the bitmap we have already stored for that commit and OR it with the existing bitmap we've composed so far, allowing us to limit the walk early. After all the bitmaps have been generated, another iteration through the list of commits is performed to find the best XOR offsets for compression before writing them to disk. Because of the incremental nature of these bitmaps, XORing one of them with its predecesor results in a minimal "bitmap delta" most of the time. We can write this delta to the on-disk bitmap index, and then re-compose the original bitmaps by XORing them again when loaded. This is a phase very similar to pack-object's `find_delta` (using bitmaps instead of objects, of course), except the heuristics have been greatly simplified: we only check the 10 bitmaps before any given one to find best compressing one. This gives good results in practice, because there is locality in the ordering of the objects (and therefore bitmaps) in the packfile. 6. `bitmap_writer_finish`: the last step in the process is serializing to disk all the bitmap data that has been generated in the two previous steps. The bitmap is written to a tmp file and then moved atomically to its final destination, using the same process as `pack-write.c:write_idx_file`.

2013-12-30pack-bitmap: add support for bitmap indexesLibravatar Vicent Marti1-0/+2
A bitmap index is a `.bitmap` file that can be found inside `$GIT_DIR/objects/pack/`, next to its corresponding packfile, and contains precalculated reachability information for selected commits. The full specification of the format for these bitmap indexes can be found in `Documentation/technical/bitmap-format.txt`. For a given commit SHA1, if it happens to be available in the bitmap index, its bitmap will represent every single object that is reachable from the commit itself. The nth bit in the bitmap is the nth object in the packfile; if it's set to 1, the object is reachable. By using the bitmaps available in the index, this commit implements several new functions: - `prepare_bitmap_git` - `prepare_bitmap_walk` - `traverse_bitmap_commit_list` - `reuse_partial_packfile_from_bitmap` The `prepare_bitmap_walk` function tries to build a bitmap of all the objects that can be reached from the commit roots of a given `rev_info` struct by using the following algorithm: - If all the interesting commits for a revision walk are available in the index, the resulting reachability bitmap is the bitwise OR of all the individual bitmaps. - When the full set of WANTs is not available in the index, we perform a partial revision walk using the commits that don't have bitmaps as roots, and limiting the revision walk as soon as we reach a commit that has a corresponding bitmap. The earlier OR'ed bitmap with all the indexed commits can now be completed as this walk progresses, so the end result is the full reachability list. - For revision walks with a HAVEs set (a set of commits that are deemed uninteresting), first we perform the same method as for the WANTs, but using our HAVEs as roots, in order to obtain a full reachability bitmap of all the uninteresting commits. This bitmap then can be used to: a) limit the subsequent walk when building the WANTs bitmap b) finding the final set of interesting commits by performing an AND-NOT of the WANTs and the HAVEs. If `prepare_bitmap_walk` runs successfully, the resulting bitmap is stored and the equivalent of a `traverse_commit_list` call can be performed by using `traverse_bitmap_commit_list`; the bitmap version of this call yields the objects straight from the packfile index (without having to look them up or parse them) and hence is several orders of magnitude faster. As an extra optimization, when `prepare_bitmap_walk` succeeds, the `reuse_partial_packfile_from_bitmap` call can be attempted: it will find the amount of objects at the beginning of the on-disk packfile that can be reused as-is, and return an offset into the packfile. The source packfile can then be loaded and the bytes up to `offset` can be written directly to the result without having to consider the entires inside the packfile individually. If the `prepare_bitmap_walk` call fails (e.g. because no bitmap files are available), the `rev_info` struct is left untouched, and can be used to perform a manual rev-walk using `traverse_commit_list`. Hence, this new set of functions are a generic API that allows to perform the equivalent of git rev-list --objects [roots...] [^uninteresting...] for any set of commits, even if they don't have specific bitmaps generated for them. In further patches, we'll use this bitmap traversal optimization to speed up the `pack-objects` and `rev-list` commands.

2013-12-30ewah: compressed bitmap implementationLibravatar Vicent Marti1-2/+9
EWAH is a word-aligned compressed variant of a bitset (i.e. a data structure that acts as a 0-indexed boolean array for many entries). It uses a 64-bit run-length encoding (RLE) compression scheme, trading some compression for better processing speed. The goal of this word-aligned implementation is not to achieve the best compression, but rather to improve query processing time. As it stands right now, this EWAH implementation will always be more efficient storage-wise than its uncompressed alternative. EWAH arrays will be used as the on-disk format to store reachability bitmaps for all objects in a repository while keeping reasonable sizes, in the same way that JGit does. This EWAH implementation is a mostly straightforward port of the original `javaewah` library that JGit currently uses. The library is self-contained and has been embedded whole (4 files) inside the `ewah` folder to ease redistribution. The library is re-licensed under the GPLv2 with the permission of Daniel Lemire, the original author. The source code for the C version can be found on GitHub: https://github.com/vmg/libewok The original Java implementation can also be found on GitHub: https://github.com/lemire/javaewah [jc: stripped debug-only code per Peff's $gmane/239768] Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Jeff King <peff@peff.net> Helped-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-11-18add a hashtable implementation that supports O(1) removalLibravatar Karsten Blees1-0/+3
The existing hashtable implementation (in hash.[ch]) uses open addressing (i.e. resolve hash collisions by distributing entries across the table). Thus, removal is difficult to implement with less than O(n) complexity. Resolving collisions of entries with identical hashes (e.g. via chaining) is left to the client code. Add a hashtable implementation that supports O(1) removal and is slightly easier to use due to builtin entry chaining. Supports all basic operations init, free, get, add, remove and iteration. Also includes ready-to-use hash functions based on the public domain FNV-1 algorithm (http://www.isthe.com/chongo/tech/comp/fnv). The per-entry data structure (hashmap_entry) is piggybacked in front of the client's data structure to save memory. See test-hashmap.c for usage examples. The hashtable is resized by a factor of four when 80% full. With these settings, average memory consumption is about 2/3 of hash.[ch], and insertion is about twice as fast due to less frequent resizing. Lookups are also slightly faster, because entries are strictly confined to their bucket (i.e. no data of other buckets needs to be traversed).

2013-10-24pack-objects: refactor the packing listLibravatar Vicent Marti1-0/+2
The hash table that stores the packing list for a given `pack-objects` run was tightly coupled to the pack-objects code. In this commit, we refactor the hash table and the underlying storage array into a `packing_data` struct. The functionality for accessing and adding entries to the packing list is hence accessible from other parts of Git besides the `pack-objects` builtin. This refactoring is a requirement for further patches in this series that will require accessing the commit packing list from outside of `pack-objects`. The hash table implementation has been minimally altered: we now use table sizes which are always a power of two, to ensure a uniform index distribution in the array.

2013-10-14sparse: suppress some "using sizeof on a function" warningsLibravatar Ramsay Jones1-0/+3
Sparse issues an "using sizeof on a function" warning for each call to curl_easy_setopt() which sets an option that takes a function pointer parameter. (currently 12 such warnings over 4 files.) The warnings relate to the use of the "typecheck-gcc.h" header file which adds a layer of type-checking macros to the curl function invocations (for gcc >= 4.3 and !__cplusplus). As part of the type-checking layer, 'sizeof' is applied to the function parameter of curl_easy_setopt(). Note that, in the context of sizeof, the function to function pointer conversion is not performed and that sizeof(f) != sizeof(&f). A simple solution, therefore, would be to replace the function name in each such call to curl_easy_setopt() with an explicit function pointer expression (i.e. replace f with &f). However, the "typecheck-gcc.h" header file is only conditionally included, in addition to the gcc and C++ checks mentioned above, depending on the CURL_DISABLE_TYPECHECK preprocessor variable. In order to suppress the warnings, we use target-specific variable assignments to add -DCURL_DISABLE_TYPECHECK to SPARSE_FLAGS for each file affected (http-push.c, http.c, http-walker.c and remote-curl.c).

When it was originally added, the git_remote_helpers library was used as part of the tests of the remote-helper interface, but since commit fc407f9 (Add new simplified git-remote-testgit, 2012-11-28) a simple shell script is used for this. A search on Ohloh [1] indicates that this library isn't used by any external projects and even the Python remote helpers in contrib/ don't use this library, so it is only used by its own test suite. Since this is the only Python library in Git, removing it will make packaging easier as the Python scripts only need to be installed for one version of Python, whereas the library should be installed for all available versions.

It used to be that APPLE_COMMON_CRYPTO did nothing when BLK_SHA1 was set. But APPLE_COMMON_CRYPTO is now used for more than just SHA1 (see 3ef2bca) so make sure that the appropriate libraries are always set.

Cygwin port added a "not quite correct but a lot faster and good enough for many lstat() calls that are only used to see if the working tree entity matches the index entry" lstat() emulation some time ago, and it started biting us in places. This removes it and uses the standard lstat() that comes with Cygwin. Recent topic that uses lstat on packed-refs file is broken when this cheating lstat is used, and this is a simplest fix that is also the cleanest direction to go in the long run. * rj/cygwin-clarify-use-of-cheating-lstat: cygwin: Remove the Win32 l/stat() implementation

2013-07-18cygwin: Remove the Win32 l/stat() implementationLibravatar Ramsay Jones1-1/+0
Commit adbc0b6b ("cygwin: Use native Win32 API for stat", 30-09-2008) added a Win32 specific implementation of the stat functions. In order to handle absolute paths, cygwin mount points and symbolic links, this implementation may fall back on the standard cygwin l/stat() functions. Also, the choice of cygwin or Win32 functions is made lazily (by the first call(s) to l/stat) based on the state of some config variables. Unfortunately, this "schizophrenic stat" implementation has been the source of many problems ever since. For example, see commits 7faee6b8, 79748439, 452993c2, 085479e7, b8a97333, 924aaf3e, 05bab3ea and 0117c2f0. In order to avoid further problems, such as the issue raised by the new reference handling API, remove the Win32 l/stat() implementation.

2013-07-13builtin: add git-check-mailmap commandLibravatar Eric Sunshine1-0/+1
Introduce command check-mailmap, similar to check-attr and check-ignore, which allows direct testing of .mailmap configuration. As plumbing accessible to scripts and other porcelain, check-mailmap publishes the stable, well-tested .mailmap functionality employed by built-in Git commands. Consequently, script authors need not re-implement .mailmap functionality manually, thus avoiding potential quirks and behavioral differences.
