nulltoken 031f3f80 2013-09-07T22:39:05 odb: Error when streaming in too [few|many] bytes
nulltoken 4047950f 2013-08-29T14:19:34 odb: Prevent stream_finalize_write() from overwriting Now that #1785 is merged, git_odb_stream_finalize_write() calculates the object id before invoking the odb backend. This commit gives a chance to the backend to check if it already knows this object.
Edward Thomson 67c177ef 2013-08-19T11:42:50 Don't expose git_hash_ctx since it's internal And doing so makes the mingw build choke.
Carlos Martín Nieto 7a3764be 2013-08-17T01:55:52 odb: document git_odb_stream Clarify the role of each function and in particular mention that there is no need for the backend or stream to worry about the object's id, as it will be given when `finalize_write` is called.
Carlos Martín Nieto fe0c6d4e 2013-08-17T01:41:08 odb: make it clearer that the id is calculated in the frontend The frontend is in charge of calculating the id of the objects. Thus the backends should treat it as a read-only value. The positioning in the function signature made it seem as though it was an output parameter. Make the id const and move it from the front to behind the subject (backend or stream).
Carlos Martín Nieto 8380b39a 2013-08-15T14:29:39 odb: perform the stream hashing in the frontend Hash the data as it's coming into the stream and tell the backend what its name is when finalizing the write. This makes it consistent with the way a plain git_odb_write() performs the write.
Russell Belfer 0f1f9833 2013-05-24T10:32:07 Add typedefs on some public enums Apparently this makes things easier to bind in some languages.
Carlos Martín Nieto 9a9de29d 2013-04-23T19:08:13 Document the odb backend constructors
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.
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.
Edward Thomson 359fc2d2 2013-01-08T17:07:25 update copyrights
David Michael Barr 4d185dd9 2012-12-19T14:30:06 odb: check if object exists before writing Update the procondition of git_odb_backend::write. It may now be assumed that the object has already been hashed.
Ben Straub fac43c54 2012-12-06T19:41:52 Allow compilation as C++
Ben Straub bde336ea 2012-11-29T12:26:09 Add version fields and init macros for public input structs.
Russell Belfer c3fb7d04 2012-11-27T15:00:49 Make git_odb_foreach_cb take const param This makes the first OID param of the ODB callback a const pointer and also propogates that change all the way to the backends.
Ben Straub 0ed67c1c 2012-11-27T12:33:58 API updates for odb_backend.h
Edward Thomson 09cc0b92 2012-11-05T11:33:10 create callback to handle packs from fetch, move the indexer to odb_pack
Philip Kelley c49d328c 2012-08-27T09:59:13 Expose a malloc function to 3rd party ODB backends
Vicent Marti e25dda51 2012-08-02T01:38:30 Merge remote-tracking branch 'nulltoken/topic/amd64-compat' into development Conflicts: src/netops.c src/netops.h src/oid.c
nulltoken b8457baa 2012-07-24T07:57:58 portability: Improve x86/amd64 compatibility
Carlos Martín Nieto 507523c3 2012-07-21T16:23:49 odb: allow creating an ODB backend from a packfile index git_odb_backend_one_packfile() allows us to create an ODB backend out of an .idx file.
Carlos Martín Nieto 521aedad 2012-06-05T14:48:51 odb: add git_odb_foreach() Go through each backend and list every objects that exists in them. This allows fsck-like uses.
Vicent Martí 2e2e9785 2012-05-18T00:42:24 Properly tag all `enums` with a `_t`

Vicent Marti 8af4d074 2011-09-29T15:34:17 odb: Let users decide compression level for the loose ODB
Vicent Marti bb742ede 2011-09-19T01:54:32 Cleanup legal data 1. The license header is technically not valid if it doesn't have a copyright signature. 2. The COPYING file has been updated with the different licenses used in the project. 3. The full GPLv2 header in each file annoys me.
Vicent Marti b0233216 2011-06-12T11:40:14 Remove custom backends All the custom backend code will be moved to a separate project, together with the new MySQL backend.
Vicent Marti d0323a5f 2011-06-01T21:25:56 short-oid: Cleanup
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 815c9bc7 2011-03-23T20:18:34 Remove circular dependency in includes
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>
