Git::Raw::Odb - Git object database class


version 0.79


A Git::Raw::Odb represents a git object database.

WARNING: The API of this module is unstable and may change without warning (any change will be appropriately documented in the changelog).


new( )

Create a new object database.

open( $directory )

Create a new object database and automatically add the two default backends. $directory should be the path to the 'objects' directory.

backend_count( )

Get the number of ODB backend objects.

refresh( )

Refresh the object database to load newly added files. If the object databases have changed on disk while the library is running, this function will force a reload of the underlying indexes. Use this method when you're confident that an external application has tampered with the ODB.

foreach( $repo, $callback )

Run $callback for every object available in the database. The callback receives a single argument, the OID of the object. A non-zero return value will terminate the loop.

add_backend( $backend, $priority )

Add a custom backend to the ODB. The backends are checked in relative ordering, based on the value of $priority.

add_alternate( $backend, $priority )

Add an alternate custom backend to the ODB. Alternate backends are always checked for objects after all the main backends have been exhausted. Writing is disabled on alternate backends.

read( $id )

Read an object from the database. Returns a Git::Raw::Odb::Object or "undef" if the object does not exist.

write( $data, type )

Write an object directly to the database. Returns the OID of the object. $type should be one of the values as defines in the constants section of Git::Raw::Object.

hash( $data, $type )

Determine the object-ID (sha1 hash) of $data. $type should be one of the values as defined in the constants section of Git::Raw::Object.
