Vicent Marti adc0327a 2010-10-29T00:44:15 Add git_odb_read_header method to the ODB As requested, git_odb_read_header looks up an object on the ODB, but loads only the header information (type & size) without loading any of the actual file contents in memory. It is significantly faster than doing a git_odb_read if you only need an object's information and not its contents. Signed-off-by: Vicent Marti <tanoku@gmail.com>
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 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>

Ramsay Jones 82324ac1 2009-02-10T21:49:48 Add the git_odb_exists() object query function This function determines if the given object can be found in the object database. At present, only the local object database is searched. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

Andreas Ericsson ec250c6e 2008-11-23T22:37:55 Remove config.h and make fileops an internal API Since it doesn't make sense to make the disk access stuff portable *AND* public (that's a job for each application imo), we can take a shortcut and just support unixy stuff for now and get away with coding most of it as macros. Since we go with an internal API for starters and only provide higher-level API's to the libgit users, we'll be ok with this approach.

Andreas Ericsson c6ebb4a9 2008-11-22T15:17:17 Remove license top-comment from public header files Since it's being added when we install the headers anyway, we might as well get rid of it. If anything, we should point coders to the COPYING file in the project's root directory instead of duplicating the same (large-ish) text everywhere.

Andreas Ericsson d4043ee9 2008-11-18T01:18:52 Move public headers to src/git It's arguably smoother to keep them close to the source, as that's where one's working when modifying them. More importantly, though, is the ability to use private headers in the src/ dir that simply include "git/$samename.h" to get to the public API at the same time.
