* I broke your bindingsVicent Marti2011-03-201-4/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Fix file renaming in MinGWVicent Marti2011-02-241-4/+2
| | | | | | | | | | | We now use MoveFileEx, which is not assured to be atomic but works for always (both if the destination exists, or if it doesn't) and is available in MinGW.

* Fix renaming of files in Win32Vicent Marti2011-02-241-0/+12
| | | | | | | | The `rename` call doesn't quite work on Win32: expects the destination file to not exist. We're using a native Win32 call in those cases -- that should do the trick. Signed-off-by: Vicent Marti <tanoku@gmail.com>

| * Added git_prettify_dir_path().nulltoken2011-01-111-0/+77
| | | | | | | | | | | | | | | | | | | | Clean up a provided absolute or relative directory path. This prettification relies on basic operations such as coalescing multiple forward slashes into a single slash, removing '.' and './' current directory segments, and removing parent directory whenever '..' is encountered. If not empty, the returned path ends with a forward slash. For instance, this will turn "d1/s1///s2/..//../s3" into "d1/s3/". This only performs a string based analysis of the path. No checks are done to make sure the path actually makes sense from the file system perspective.

* win32: Add routines to abstract memory-mapped file functionsRamsay Jones2009-03-201-6/+4
| | | | | | | | | | In particular, the git__mmap() and git__munmap() routines provide the interface to platform specific memory-mapped file facilities. We provide implementations for unix and win32, which can be found in their own sub-directories. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O.

* win32: Open or create files in binary modeRamsay Jones2009-03-171-2/+2
| | | | | | | | | | | | On windows, unless we use the O_BINARY flag in the open() call, the file I/O routines will perform line ending conversion (\r\n => \n on input, \n => \r\n on output). In addition to the performance penalty, most files in the object database are binary and will, therefore, become corrupted by this conversion.

* Avoid using a gcc compiler language extensionRamsay Jones2009-03-171-2/+4
| | | | | | | | | | In particular, using pointer arithmetic on void pointers, despite being quite useful, is not legal in standard C. Avoiding non-standard C constructs will help in porting the library to other compilers/platforms. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Add a simple mmap wrapper for cross-platform mmap usageShawn O. Pearce2009-01-031-0/+15
| | | | | | | | | | | Win32 has a variant of mmap that is harder to use than POSIX, but to run natively and efficiently on Win32 we need some form of it. gitfo_map_ro() provides a basic mmap function for use in locations where we need read-only random data access to large ranges of a file, such as a pack-*.idx. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Define gitfo_exists to determine file presenceShawn O. Pearce2008-12-311-0/+6
| | | | | | | When scanning the pack directory we need to see if the path name is present for ".idx" when we discover a ".pack" file. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Rewrite git_foreach_dirent into gitfo_direntShawn O. Pearce2008-12-311-15/+9
| | | | | | | | | | | | | | Our fileops API is currently private. We aren't planning on supplying a cross-platform file API to applications that link to us. If we did, we'd probably whole-sale publish fileops, not just the dirent code. By moving it to be private we can also change the call signature to permit the buffer to be passed down through the call chain. This is very helpful when we are doing a recursive scan as we can reuse just one buffer in all stack frames, reducing the impact the recursion has on the stack frames in the data cache.

* Set GIT_EOSERR when the OS errno should be consultedShawn O. Pearce2008-12-301-8/+20
| | | | | | | | This error code indicates the OS error code has a better value describing the last error, as it is likely a network or local file IO problem identified by a C library function call. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* Wrap malloc and friends and report out of memory as GIT_ENOMEMShawn O. Pearce2008-12-301-6/+7
| | | | | | | | | | | | | | | | We now forbid direct use of malloc, strdup or calloc within the library and instead use wrapper functions git__malloc, etc. to invoke the underlying library malloc and set git_errno to a no memory error code if the allocation fails. In the future once we have pack objects in memory we are likely to enhance these routines with garbage collection logic to purge cached pack data when allocations fail. Because the size of the function will grow somewhat large, we don't want to mark them for inline as gcc tends to aggressively inline, creating larger than expected executables.

* Fix a bug in gitfo_read_file()Ramsay Jones2008-12-301-2/+3
| | | | | | | | | | | | | | | | | | | In particular, when asked to read an empty file, this function calls malloc() with a zero size allocation request. Standard C says that the behaviour of malloc() in this case is implementation defined. [C99, 7.20.3 says "... If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object."] Finesse the issue by over-allocating by one byte. Setting the extra byte to '\0' may also provide a useful sentinel for text files. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
