Russell Belfer 3f27127d 2013-04-16T11:51:02 Simplify object table parse functions This unifies the object parse functions into one signature that takes an odb_object.
Russell Belfer 78606263 2013-04-15T00:05:44 Add callback to git_objects_table This adds create and free callback to the git_objects_table so that more of the creation and destruction of objects can be table driven instead of using switch statements. This also makes the semantics of certain object creation functions consistent so that we can make better use of function pointers. This also fixes a theoretical error case where an object allocation fails and we end up storing NULL into the cache.
Russell Belfer badd85a6 2013-04-10T17:10:17 Use git_odb_object_data/_size whereever possible This uses the odb object accessors so we can change the internals more easily...
Vicent Marti 8842c75f 2013-04-03T22:30:07 What has science done.
Russell Belfer 9233b3de 2013-04-19T13:17:29 Move git_commit_create_from_oids into sys/commit.h Actually this renames git_commit_create_oid to git_commit_create_from_oids and moves the API declaration to include/git2/sys/commit.h since it is a dangerous API for general use (because it doesn't check that the OID list items actually refer to real objects).
John Wiegley 92550398 2013-01-29T09:53:23 Added git_commit_create_oid
Carlos Martín Nieto 0efae3b2 2013-04-15T12:24:08 commit: correctly detect the start of the commit message The end of the header is signaled by to consecutive LFs and the commit message starts immediately after. Jumping over LFs at the start of the message is a bug and leads to creating different commits if when rebuilding history. This also fixes an empty commit message being returned as "\n".

Carlos Martín Nieto d47c6aab 2013-01-20T04:20:09 commit: don't include the LF in the header field value When the encoding header changed to be treated as an additional header, the EOL pointer started to point to the byte after the LF, making the git__strndup call copy the LF into the value. Increase the EOL pointer value after copying the data to keep the rest of the semantics but avoid copying LF.
Russell Belfer 291090a0 2013-01-17T13:19:09 Add skipping of unknown commit headers This moves the check for the "encoding" header into a loop which is just scanning for non-required headers at the end of a commit header. That loop will skip unrecognized lines (including header continuation lines) until a terminating completely blank line is found, and only then does it move to reading the commit message.

Vicent Martí cb8a7961 2012-03-07T00:02:55 error-handling: Repository This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.

Russell Belfer 97769280 2011-11-30T11:27:15 Use git_buf for path storage instead of stack-based buffers This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.
Vicent Marti 9462c471 2011-11-25T08:16:26 repository: Change ownership semantics 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.

schu a46ec457 2011-08-10T16:19:42 refs: split internal and external references Currently libgit2 shares pointers to its internal reference cache with the user. This leads to several problems like invalidation of reference pointers when reordering the cache or manipulation of the cache from user side. Give each user its own git_reference instead of leaking the internal representation (struct reference). Add the following new API functions: * git_reference_free * git_reference_is_packed Signed-off-by: schu <schu-github@schulog.org>

Vicent Marti 06c43821 2011-07-09T02:37:16 Remove unused methods The direct-writes commit left some (slow) internals methods that were no longer needed. These have been removed. Also, the Reflog code was using the old `git_signature__write`, so it has been rewritten to use a normal buffer and the new `writebuf` signature writer. It's now slightly simpler and faster.
Vicent Marti afeecf4f 2011-07-09T02:10:46 odb: Direct writes are back DIRECT WRITES ARE BACK AND FASTER THAN EVER. The streaming writer to the ODB was an overkill for the smaller objects like Commit and Tags; most of the streaming logic was taking too long. This commit makes Commits, Tags and Trees to be built-up in memory, and then written to disk in 2 pushes (header + data), instead of streaming everything. This is *always* faster, even for big files (since the git_filebuf class still does streaming writes when the memory cache overflows). This is also a gazillion lines of code smaller, because we don't have to precompute the final size of the object before starting the stream (this was kind of defeating the point of streaming, anyway). Blobs are still written with full streaming instead of loading them in memory, since this is still the fastest way. A new `git_buf` class has been added. It's missing some features, but it'll get there.

Vicent Marti d5afc039 2011-06-28T19:15:48 Remove redundant methods from the API A bunch of redundant methods have been removed from the external API. - All the reference/tag creation methods with `_f` are gone. The force flag is now passed as an argument to the normal create methods. - All the different commit creation methods are gone; commit creation now always requires a `git_commit` pointer for parents and a `git_tree` pointer for tree, to ensure that corrupted commits cannot be generated. - All the different tag creation methods are gone; tag creation now always requires a `git_object` pointer to ensure that tags are not created to inexisting objects.

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 b5c5f0f8 2011-03-16T23:59:09 Fix headers for the new Revision Walker The "oid.h" header is now included instead of "object.h". The old "revwalk.h" header has been removed; it was empty.
Vicent Marti 6b2a1941 2011-03-12T23:09:16 Fix the retarded object interdependency system It's no longer retarded. All object interdependencies are stored as OIDs instead of actual objects. This should be hundreds of times faster, specially on big repositories. Heck, who knows, maye it doesn't even segfault -- wouldn't that be awesome? What has changed on the API? `git_commit_parent`, `git_commit_tree`, `git_tag_target` now return their values through a pointer-to-pointer, and have an error code. `git_commit_set_tree` and `git_tag_set_target` now return an error code and may fail. `git_repository_free__no_gc` has been deprecated because it's stupid. Since there are no longer any interdependencies between objects, we don't need internal reference counting, and GC never fails or double-free's pointers. `git_object_close` now does a very sane thing: marks an object as unused. Closed objects will be eventually free'd from the object cache based on LRU. Please use `git_object_close` from the garbage collector `destroy` method on your bindings. It's 100% safe. `git_repository_gc` is a new method that forces a garbage collector pass through the repo, to free as many LRU objects as possible. This is useful if we are running out of memory.

So far, only git_commits can be written back to disk once created in memory. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 0c3596f1 2010-09-20T01:57:53 Add setter methods & write support for git_commit All the required git_commit_set_XXX methods have been implemented; all the attributes of a commit object can now be modified in-memory. The new method git_object_write() automatically writes back the in-memory changes of any object to the repository. So far it only supports git_commit objects.

Vicent Marti f49a2e49 2010-09-19T03:21:06 Give object structures more descriptive names The 'git_obj' structure is now called 'git_rawobj', since it represents a raw object read from the ODB. The 'git_repository_object' structure is now called 'git_object', since it's the base object class for all objects. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti a7a7ddbe 2010-09-18T19:16:04 Add generic methods for object writeback git_repository_object has now several internal methods to write back the object information in the repository. - git_repository__dbo_prepare_write() Prepares the DBO object to be modified - git_repository__dbo_write() Writes new bytes to the DBO object - git_repository__dbo_writeback() Writes back the changes to the repository Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti f2408cc2 2010-08-12T19:59:32 Fix object handling in git_repository All loaded objects through git_repository_lookup are properly parsed & free'd on failure. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 3315782c 2010-08-08T14:12:17 Redesigned the walking/object lookup interface The old 'git_revpool' object has been removed and split into two distinct objects with separate functionality, in order to have separate methods for object management and object walking. * A new object 'git_repository' does the high-level management of a repository's objects (commits, trees, tags, etc) on top of a 'git_odb'. Eventually, it will also manage other repository attributes (e.g. tag resolution, references, etc). See: src/git/repository.h * A new external method 'git_repository_lookup(repo, oid, type)' has been added to the 'git_repository' API. All object lookups (git_XXX_lookup()) are now wrappers to this method, and duplicated code has been removed. The method does automatic type checking and returns a generic 'git_revpool_object' that can be cast to any specific object. See: src/git/repository.h * The external methods for object parsing of repository objects (git_XXX_parse()) have been removed. Loading objects from the repository is now managed through the 'lookup' functions. These objects are loaded with minimal information, and the relevant parsing is done automatically when the user requests any of the parsed attributes through accessor methods. An attribute has been added to 'git_repository' in order to force the parsing of all the repository objects immediately after lookup. See: src/git/commit.h See: src/git/tag.h See: src/git/tree.h * The previous walking functionality of the revpool is now found in 'git_revwalk', which does the actual revision walking on a repository; the attributes when walking through commits in a database have been decoupled from the actual commit objects. This increases performance when accessing commits during the walk and allows to have several 'git_revwalk' instances working at the same time on top of the same repository, without having to load commits in memory several times. See: src/git/revwalk.h * The old 'git_revpool_table' has been renamed to 'git_hashtable' and now works as a generic hashtable with support for any kind of object and custom hash functions. See: src/hashtable.h * All the relevant unit tests have been updated, renamed and grouped accordingly. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 364788e1 2010-08-07T00:59:58 Refactor parsing methods The 'parse_oid' and 'parse_person' methods which were used by the commit parser are now global so they can be used when parsing other objects. The 'git_commit_person' struct has been changed to a generic 'git_person'. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti d8603ed9 2010-07-10T16:51:15 Add parsing of tree file contents. The basic information (pointed trees and blobs) of each tree object in a revision pool can now be parsed and queried. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 52f2390b 2010-07-07T14:56:05 Add external API to access detailed commit attributes The following new external methods have been added: GIT_EXTERN(const char *) git_commit_message_short(git_commit *commit); GIT_EXTERN(const char *) git_commit_message(git_commit *commit); GIT_EXTERN(time_t) git_commit_time(git_commit *commit); GIT_EXTERN(const git_commit_person *) git_commit_committer(git_commit *commit); GIT_EXTERN(const git_commit_person *) git_commit_author(git_commit *commit); GIT_EXTERN(const git_tree *) git_commit_tree(git_commit *commit); A new structure, git_commit_person has been added to represent a commit's author or committer. The parsing of a commit has been split in two phases. When adding a commit to the revision pool: - the commit's ODB object is opened - its raw contents are parsed for commit TIME, PARENTS and TREE (the minimal amount of data required to traverse the pool) - the commit's ODB object is closed When querying for extended information on a commit: - the commit's ODB object is reopened - its raw contents are parsed for the requested information - the commit's ODB object remains open to handle additional queries New unit tests have been added for the new functionality: In t0401-parse: parse_person_test In t0402-details: query_details_test Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 225fe215 2010-06-18T13:06:34 Add support for tree objects in revision pools Commits now store pointers to their tree objects. Tree objects now work as separate git_revpool_object entities. Tree objects can be loaded and parsed inedependently from commits. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 40721f6b 2010-07-10T11:50:16 Changed revpool's object table to support arbitrary objects git_revpool_object now has a type identifier for each object type in a revpool (commits, trees, blobs, etc). Trees can now be stored in the revision pool. git_revpool_tableit now supports filtering objects by their type when iterating through the object table. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 088a731f 2010-06-09T14:54:22 Fixed memory leaks in test suite Created commit objects in t0401-parse weren't being freed properly. Updated the API documentation to note that commit objects are owned by the revision pool and should not be freed manually. The parents list of each commit was being freed twice after each test.

Ramsay Jones 28f98329 2010-06-01T19:37:10 Fix inconsistent definition of off_t on Linux In order to avoid inconsistent definitions of type off_t, all compilation units should include the "common.h" header file before certain system headers (those which directly or indirectly lead to the definition of off_t). The "common.h" header contains the definition of _FILE_OFFSET_BITS to select 64-bit file offsets. The symptom of this inconsistency, while compiling with -Wextra, is the following warning: In file included from src/common.h:50, from src/commit.c:28: src/util.h: In function git__is_sizet: src/util.h:41: warning: comparison between signed and unsigned In order to fix the problem, we simply remove the #include <time.h> statement at the head of src/commit.c. Note that src/commit.h also includes <time.h>. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Andreas Ericsson <ae@op5.se>
