* odb: make the writestream's size a git_off_tcmn/stream-sizeCarlos Martín Nieto2015-05-131-1/+1
| | | | | | | | | | Restricting files to size_t is a silly limitation. The loose backend writes to a file directly, so there is no issue in using 63 bits for the size. We still assume that the header is going to fit in 64 bytes, which does mean quite a bit smaller files due to the run-length encoding, but it's still a much larger size than you would want Git to handle.

* odb: wrap the stream reading and writing functionsCarlos Martín Nieto2013-08-151-10/+39
| | | | | | This is in preparation for moving the hashing to the frontend, which requires us to handle the incoming data before passing it to the backend's stream.
* More tests for ambiguous OIDs across packsRussell Belfer2013-08-051-1/+1
| | | | | | | The test coverage for ambiguous OIDs was pretty thin. This adds a bunch of new objects both in packs, across packs, and loose that match to 8 characters so that we can test various cases of ambiguous lookups.
* Move odb_backend implementors stuff into git2/sysRussell Belfer2013-04-211-38/+59
| | | | | | | | | | | | 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.
* Sane refresh logicVicent Marti2013-01-101-0/+20
| | | | | | | 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.

* odb: Add `git_odb_add_disk_alternate`Vicent Marti2012-11-281-0/+17
| | | | | Loads a disk alternate by path to the ODB. Mimics the `GIT_ALTERNATE_OBJECT_DIRECTORIES` shell var.
* Make git_odb_foreach_cb take const paramRussell Belfer2012-11-271-5/+0
| | | | | This makes the first OID param of the ODB callback a const pointer and also propogates that change all the way to the backends.

| * Update iterators for consistency across libraryRussell Belfer2012-08-031-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Rename all `_close` methodsVicent Marti2011-11-261-1/+1
| | | | | There's no difference between `_free` and `_close` semantics: keep everything with the same name to avoid confusions.
* repository: Change ownership semanticsVicent Marti2011-11-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ownership semantics have been changed all over the library to be consistent. There are no more "borrowed" or duplicated references. Main changes: - `git_repository_open2` and `3` have been dropped. - Added setters and getters to hotswap all the repository owned objects: `git_repository_index` `git_repository_set_index` `git_repository_odb` `git_repository_set_odb` `git_repository_config` `git_repository_set_config` `git_repository_workdir` `git_repository_set_workdir` Now working directories/index files/ODBs and so on can be hot-swapped after creating a repository and between operations. - All these objects now have proper ownership semantics with refcounting: they all require freeing after they are no longer needed (the repository always keeps its internal reference). - Repository open and initialization has been updated to keep in mind the configuration files. Bare repositories are now always detected, and a default config file is created on init. - All the tests affected by these changes have been dropped from the old test suite and ported to the new one.
* Tabify everythingVicent Marti2011-09-191-3/+3
| | | | | | There were quite a few places were spaces were being used instead of tabs. Try to catch them all. This should hopefully not break anything. Except for `git blame`. Oh well.
* Cleanup legal dataVicent Marti2011-09-191-22/+4
| | | | | | | | | | 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.

* status: CleanupVicent Marti2011-07-091-0/+13
| | | | | | | | The `hashfile` function has been moved to ODB, next to `git_odb_hash`. Global state has been removed from the dirent call in `status.c`, because global state is killing the rainforest and causing global warming.

* Added git.git sha1 lookup method to replace simple binary search in pack ↵Marc Pegon2011-06-011-1/+31
| | | | | | | | | | | | | | | 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.

| | | | | | | | | 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).

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>
