Carlos Martín Nieto a6154f21 2013-10-30T15:00:05 indexer: remove the stream infix It was there to keep it apart from the one which read in from a file on disk. This other indexer does not exist anymore, so there is no need for anything other than git_indexer to refer to it. While here, rename _add() function to _append() and _finalize() to _commit(). The former change is cosmetic, while the latter avoids talking about "finalizing", which OO languages use to mean something completely different.
Vicent Martí 5c50f22a 2013-10-28T09:25:44 Merge pull request #1891 from libgit2/cmn/fix-thin-packs Add support for thin packs
Carlos Martín Nieto 0b33fca0 2013-10-02T13:39:35 indexer: fix thin packs When given an ODB from which to read objects, the indexer will attempt to inject the missing bases at the end of the pack and update the header and trailer to reflect the new contents.
Russell Belfer 219d3457 2013-10-01T16:12:15 Initial iconv hookup for precomposed unicode This hooks up git_path_direach and git_path_dirload so that they will take a flag indicating if directory entry names should be tested and converted from decomposed unicode to precomposed form. This code will only come into play on the Apple platform and even then, only when certain types of filesystems are used. This involved adding a flag to these functions which involved changing a lot of places in the code. This was an opportunity to do a bit of code cleanup here and there, for example, getting rid of the git_futils_cleanupdir_r function in favor of a simple flag to git_futils_rmdir_r to not remove the top level entry. That ended up adding depth tracking during rmdir_r which led to a safety check for infinite directory recursion. Yay. This hasn't actually been tested on the Mac filesystems where the issue occurs. I still need to get test environment for that.

nulltoken b1a6c316 2013-08-30T17:36:00 odb: Move the auto refresh logic to the pack backend Previously, `git_object_read()`, `git_object_read_prefix()` and `git_object_exists()` were implementing an auto refresh logic. When the expected object couldn't be found in any backend, a call to `git_odb_refresh()` was triggered and the lookup was once again performed against all backends. This commit removes this auto-refresh logic from the odb layer and pushes it down into the pack-backend (as it's the only one currently exposing a `refresh()` endpoint).

Brodie Rao d19bcb33 2013-06-06T14:49:14 odb_pack: handle duplicate objects from different packs This is based on 24634c6fd02b2240e4a93fad70a08220f8fb793a. This also corrects an issue with error codes being mixed up with the number of found objects.
Russell Belfer 5d2d21e5 2013-04-16T15:00:43 Consolidate packfile allocation further Rename git_packfile_check to git_packfile_alloc since it is now being used more in that capacity. Fix the various places that use it. Consolidate some repeated code in odb_pack.c related to the allocation of a new pack_backend.
Russell Belfer 83cc70d9 2013-04-19T12:48:33 Move odb_backend implementors stuff into git2/sys This moves some of the odb_backend stuff that is related to the internals of an odb_backend implementation into include/git2/sys. Some of the stuff related to streaming I left in include/git2 because it seemed like it would be reasonably needed by a normal user who wanted to stream objects into and out of the ODB. Also, I added APIs for traversing the list of backends so that some of the tests would not need to access ODB internals.

Carlos Martín Nieto 96c9b9f0 2013-01-12T18:38:19 indexer: properly free the packfile resources The indexer needs to call the packfile's free function so it takes care of freeing the caches. We still need to close the mwf descriptor manually so we can rename the packfile into its final name on Windows.

Vicent Marti 4a863c06 2013-01-03T20:36:26 Sane refresh logic All the ODB backends have a specific refresh interface. When reading an object, first we attempt every single backend: if the read fails, then we refresh all the backends and retry the read one more time to see if the object has appeared.

Ben Straub 5bb0dc93 2012-09-13T14:02:46 ODB: re-load packfiles on failed lookup The old method was avoiding re-loading of packfiles by watching the mtime of the pack directory. This causes the ODB to become stale if the directory and packfile are written within the same clock millisecond, as when cloning a fairly small repo. This method tries to find the object in the cached packs, and forces a refresh when that fails. This will cause extra stat'ing on a miss, but speeds up the success case and avoids this race condition.
Michael Schubert 3d7617e4 2012-09-14T21:33:50 odb_pack: fix race condition last_found is the last packfile a wanted object was found in. Since last_found is shared among all searching threads, it might changes while we're searching. As suggested by @arrbee, put a copy on the stack to fix the race condition.
David Michael Barr ab8a0402 2012-09-12T14:26:31 odb_pack: try lookup before refreshing packs This reduces the rate of syscalls for the common case of sequences of object reads from the same pack. Best of 5 timings for libgit2_clar before this patch: real 0m5.375s user 0m0.392s sys 0m3.564s After applying this patch: real 0m5.285s user 0m0.356s sys 0m3.544s 0.6% improvement in system time. 9.2% improvement in user time. 1.7% improvement in elapsed time. Confirmed a 0.6% reduction in number of system calls with strace. Expect greater improvement for graph-traversal with large packs.

Russell Belfer 5dca2010 2012-08-03T17:08:01 Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

Russell Belfer e1de726c 2012-03-12T22:55:40 Migrate ODB files to new error handling This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to the new style of error handling. Also got the unix and win32 versions of map.c. There are some minor changes to other files but no others were completely converted. This also contains an update to filebuf so that a zeroed out filebuf will not think that the fd (== 0) is actually open (and inadvertently call close() on fd 0 if cleaned up). Lastly, this was built and tested on win32 and contains a bunch of fixes for the win32 build which was pretty broken.
Vicent Martí 1a481123 2012-02-17T00:13:34 error-handling: References Yes, this is error handling solely for `refs.c`, but some of the abstractions leak all ofer the code base.
Russell Belfer 854eccbb 2012-02-29T12:04:59 Clean up GIT_UNUSED macros on all platforms It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing *count++ but meant to do (*count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file.

Russell Belfer 1744fafe 2012-01-17T15:49:47 Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).
Russell Belfer 97769280 2011-11-30T11:27:15 Use git_buf for path storage instead of stack-based buffers This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.

Vicent Marti de18f276 2011-07-07T01:46:20 vector: Timsort all of the things Drop the GLibc implementation of Merge Sort and replace it with Timsort. The algorithm has been tuned to work on arrays of pointers (void **), so there's no longer a need to abstract the byte-width of each element in the array. All the comparison callbacks now take pointers-to-elements, not pointers-to-pointers, so there's now one less level of dereferencing. E.g. int index_cmp(const void *a, const void *b) { - const git_index_entry *entry_a = *(const git_index_entry **)(a); + const git_index_entry *entry_a = (const git_index_entry *)(a); The result is up to a 40% speed-up when sorting vectors. Memory usage remains lineal. A new `bsearch` implementation has been added, whose callback also supplies pointer-to-elements, to uniform the Vector API again.

Marc Pegon ac2b94ad 2011-05-28T21:24:25 Added a GIT_OID_MINPREFIXLEN constant to define the minimum length allowed for oid prefixes (set to 4, like in git). Consequently updated some object lookup methods and their documentation.
Marc Pegon dd453c4d 2011-05-27T22:46:41 Added git.git sha1 lookup method to replace simple binary search in pack backend. Implemented find_unique_short_oid for pack backend, based on git sha1 lookup method; finding an object given its full oid is just a particular case of searching the unique object matching an oid prefix (short oid). Added git_odb_read_unique_short_oid, which iterates over all the backends to find and read the unique object matching the given oid prefix. Added a git_object_lookup_short_oid method to find the unique object in the repository matching a given oid prefix : it generalizes git_object_lookup which now does nothing but calls git_object_lookup_short_oid.
Marc Pegon ecd6fdf1 2011-05-27T18:49:09 Added a read_unique_short_oid method to backends, to make it possible to find objects from sha1 prefixes in the future. Default implementations throw GIT_ENOTIMPLEMENTED for strict prefixes (i.e. length < GIT_OID_HEXSZ).

Vicent Marti 72a3fe42 2011-03-18T19:38:49 I broke your bindings Hey. Apologies in advance -- I broke your bindings. This is a major commit that includes a long-overdue redesign of the whole object-database structure. This is expected to be the last major external API redesign of the library until the first non-alpha release. Please get your bindings up to date with these changes. They will be included in the next minor release. Sorry again! Major features include: - Real caching and refcounting on parsed objects - Real caching and refcounting on objects read from the ODB - Streaming writes & reads from the ODB - Single-method writes for all object types - The external API is now partially thread-safe The speed increases are significant in all aspects, specially when reading an object several times from the ODB (revwalking) and when writing big objects to the ODB. Here's a full changelog for the external API: blob.h ------ - Remove `git_blob_new` - Remove `git_blob_set_rawcontent` - Remove `git_blob_set_rawcontent_fromfile` - Rename `git_blob_writefile` -> `git_blob_create_fromfile` - Change `git_blob_create_fromfile`: The `path` argument is now relative to the repository's working dir - Add `git_blob_create_frombuffer` commit.h -------- - Remove `git_commit_new` - Remove `git_commit_add_parent` - Remove `git_commit_set_message` - Remove `git_commit_set_committer` - Remove `git_commit_set_author` - Remove `git_commit_set_tree` - Add `git_commit_create` - Add `git_commit_create_v` - Add `git_commit_create_o` - Add `git_commit_create_ov` tag.h ----- - Remove `git_tag_new` - Remove `git_tag_set_target` - Remove `git_tag_set_name` - Remove `git_tag_set_tagger` - Remove `git_tag_set_message` - Add `git_tag_create` - Add `git_tag_create_o` tree.h ------ - Change `git_tree_entry_2object`: New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)` - Remove `git_tree_new` - Remove `git_tree_add_entry` - Remove `git_tree_remove_entry_byindex` - Remove `git_tree_remove_entry_byname` - Remove `git_tree_clearentries` - Remove `git_tree_entry_set_id` - Remove `git_tree_entry_set_name` - Remove `git_tree_entry_set_attributes` object.h ------------ - Remove `git_object_new - Remove `git_object_write` - Change `git_object_close`: This method is now *mandatory*. Not closing an object causes a memory leak. odb.h ----- - Remove type `git_rawobj` - Remove `git_rawobj_close` - Rename `git_rawobj_hash` -> `git_odb_hash` - Change `git_odb_hash`: New signature is `(git_oid *id, const void *data, size_t len, git_otype type)` - Add type `git_odb_object` - Add `git_odb_object_close` - Change `git_odb_read`: New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)` - Change `git_odb_read_header`: New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)` - Remove `git_odb_write` - Add `git_odb_open_wstream` - Add `git_odb_open_rstream` odb_backend.h ------------- - Change type `git_odb_backend`: New internal signatures are as follows int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype) int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *) - Add type `git_odb_stream` - Add enum `git_odb_streammode` Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 58d06cf1 2011-03-10T01:06:24 Rewrite the Pack backend The new pack backend is an adaptation of the original git.git code in `sha1_file.c`. It's slightly faster than the previous version and severely less memory-hungry. The call-stack of a normal pack backend query has been properly documented in the top of the header for future reference. And by properly I mean with ASCII diagrams 'n shit.
Vicent Marti d4b5a4e2 2011-02-09T19:49:02 Internal changes on the backend system The priority value for different backends has been removed from the public `git_odb_backend` struct. We handle that internally. The priority value is specified on the `git_odb_add_alternate`. This is convenient because it allows us to poll a backend twice with different priorities without having to instantiate it twice. We also differentiate between main backends and alternates; alternates have lower priority and cannot be written to. These changes come with some unit tests to make sure that the backend sorting is consistent. The libgit2 version has been bumped to 0.4.0. This commit changes the external API: CHANGED: struct git_odb_backend No longer has a `priority` attribute; priority for the backend in managed internally by the library. git_odb_add_backend(git_odb *odb, git_odb_backend *backend, int priority) Now takes an additional priority parameter, the priority that will be given to the backend. ADDED: git_odb_add_alternate(git_odb *odb, git_odb_backend *backend, int priority) Add a backend as an alternate. Alternate backends have always lower priority than main backends, and writing is disabled on them. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Vicent Marti <tanoku@gmail.com>
Alex Budovski f0bde7fa 2011-01-11T16:07:45 Revised platform types to use 'best supported' size. This will allow graceful migration to 64 bit file sizes and timestamps should git's binary interface be extended to allow this.
