Vicent Marti f9213015 2011-06-06T01:54:59 filebuf: Fix printf buffer overflows The filebuf was not being properly written after a flush. This should cut it now. Fixes #228
Romain Geissler 1549cba9 2011-06-03T21:18:24 Filebuf: Fixed a TODO in filebuf (real lock in lock_file) Added gitfo_creat_locked and gitfo_creat_locked_force
Vicent Marti f6328611 2011-05-23T21:00:19 filebuf: Reword errors
Jakob Pfender 374db5f9 2011-05-17T17:43:00 filebuf.c: Move to new error handling mechanism
Vicent Marti a6359408 2011-04-10T12:23:55 Use Z_BEST_SPEED for filebuf deflating This is what Git uses by default for all deflating.
Vicent Marti f6f72d7e 2011-03-23T18:44:53 Improve the ODB writing backend Temporary files when doing streaming writes are now stored inside the Objects folder, to prevent issues when moving files between disks/partitions. Add support for block writes to the ODB again (for those backends that cannot implement streaming).
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 55ffebe3 2011-03-05T14:34:32 Fix creation of deeply-rooted references Use a new `gitfo_creat_force` that will create the full path to a file before creating it. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 19a30a3f 2011-03-03T19:53:17 Add new move function, `gitfo_mv_force` Forces a move by creating the folder for the destination file, if it doesn't exist. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 86194b24 2011-02-18T21:57:53 Split packed from unpacked references These two reference types are now stored separately to eventually allow the removal/renaming of loose references and rewriting of the refs packfile. Signed-off-by: Vicent Marti <tanoku@gmail.com>

Vicent Marti 817c2820 2011-02-21T17:05:16 Rewrite all file IO for more performance The new `git_filebuf` structure provides atomic high-performance writes to disk by using a write cache, and optionally a double-buffered scheme through a worker thread (not enabled yet). Writes can be done 3-layered, like in git.git (user code -> write cache -> disk), or 2-layered, by writing directly on the cache. This makes index writing considerably faster. The `git_filebuf` structure contains all the old functionality of `git_filelock` for atomic file writes and reads. The `git_filelock` structure has been removed. Additionally, the `git_filebuf` API allows to automatically hash (SHA1) all the data as it is written to disk (hashing is done smartly on big chunks to improve performance).
