![]() A group of updates can be applied by updating the tree in one step, writing out a new root tree, and storing its SHA-1. If references are stored in RefTrees, comparing two repositories is a matter of checking if two SHA-1s are identical. Without RefTrees comparing two repositories requires listing all references and comparing the sets. Track the "refs/" directory as a root tree by storing references that point directly at an object as a GITLINK entry in the tree. For example "refs/heads/master" is written as "heads/master". Annotated tags also store their peeled value with ^{} suffix, using "tags/v1.0" and "tags/v1.0^{}" GITLINK entries. Symbolic references are written as SYMLINK entries with the blob of the symlink carrying the name of the symbolic reference target. HEAD is outside of "refs/" namespace so it is stored as a special "..HEAD" entry. This name is chosen because ".." is not valid in a reference name and it almost looks like "../HEAD" which names HEAD if the reader was inside of the "refs/" directory. A new Command type is required to handle symbolic references and peeled references. Change-Id: Id47e5d4d32149a9e500854147edd7d93c1041a39 |
