* I broke your bindingsVicent Marti2011-03-201-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Add proper threading support to libgit2Vicent Marti2011-03-151-101/+20
| | | | | | | We now depend on libpthread on all Unix platforms (should be installed by default) and use a simple wrapper for Windows threads under Win32. Signed-off-by: Vicent Marti <tanoku@gmail.com>

* Improve the performance when writing Index filesVicent Marti2011-02-171-68/+88
| | | | | | | | | | | | | | In response to issue #60 (git_index_write really slow), the write_index function has been rewritten to improve its performance -- it should now be in par with the performance of git.git. On top of that, if Posix Threads are available when compiling libgit2, a new threaded writing system will be used (3 separate threads take care of solving byte-endianness, hashing the contents of the index and writing to disk, respectively). For very long Index files, this method is up to 3x times faster than git.git. Signed-off-by: Vicent Marti <tanoku@gmail.com>
* Revert "Properly export all external symbols in Win32"Vicent Marti2010-12-231-1/+1
| | | | | | | It is not a good idea to export these internal symbols now that they are not required to run the unit tests. Signed-off-by: Vicent Marti <tanoku@gmail.com>
* Properly export all external symbols in Win32Vicent Marti2010-12-221-1/+1
| | | | | | | Some external functions were not being exported because they were using the 'extern' keyword instead of the generic GIT_EXTERN() macro. Signed-off-by: Vicent Marti <tanoku@gmail.com>
* thread-utils.h: Avoid using a non-standard C constructRamsay Jones2009-06-051-1/+1
| | | | | | | | | | | | | | In particular, in standard C, a struct or union must have at least one member declared (ie. structs and unions cannot be empty). Some compilers allow empty structs as an extension and won't even issue a warning unless asked for it (eg, gcc requires -pedantic). Some compilers allow empty structs as an extension and will only treat it as an error if asked for strict checking (eg Digital-Mars with -A). Some compilers simply treat it as an error (eg MS Visual C/C++). Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Change the use of asm/atomic.h to require -DGIT_HAS_ASM_ATOMICShawn O. Pearce2009-01-021-1/+1
| | | | | | | | | These headers aren't always available; they typically come from the Linux kernel, but aren't supposed to be exported into the userspace /usr/include. Modern kernels won't install these and some distros rm -rf the directory post kernel header install. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Fix pthread_mutex based gitrc_decShawn O. Pearce2009-01-021-1/+1
| | | | | | The function should return true only when the counter drops to 0. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Add a mutex and atomic counter abstraction and implementationsShawn O. Pearce2008-12-311-1/+82
| | | | | | | | | These abstractions can be used to implement an efficient resource reference counter and simple mutual exclusion. On pthreads we use pthread_mutex_t, except when we are also on glibc and can directly use its asm/atomic.h definitions. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Add compiler/platform agnostic thread-local storageAndreas Ericsson2008-11-181-0/+8
It doesn't cover all cases, but we can work on those as we go along. For now, gcc, MSVC++, Intel C/C++, IBM XL C/C++, Sun Studio C/C++ and Borland C++ Builder are the supported compilers (although we boldly assume that they all are of a recent enough version to support thread-local storage). This is intended to be used in upcoming patches that implement graceful (but TLS-dependant) error-handling in the library. As an added bonus, we also bring the online_cpus() function from git.git to detect the number of usable cpu's. Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Shawn O.
