* plumbing: detect renames by hash and similar content in diff treeMiguel Molina2020-04-234-4/+1374
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit implements the rename detection algorithms used in the JGit implementation. Given a list of changes, additions and deletions are extracted and matched in two ways: - By exact hash content: all additions and deletions are grouped by the content hash and paired with the best match based on the file mode and file path. All the files that cannot be paired are kept as regular deletions and additions. - By similar content: a matrix of addition and deletion pairs with all possible combinations is created and scored by how similar the content is between both files as well as how similar the file path is. The pairs with the best score and whose score is equal or greater than a threshold are paired and turned into a rename. All the files that cannot be paired are kept as regular deletions and additions. DiffTree and DiffTreeContext will not return the changes with renames detected for compatibility reasons, although this will change in v6 so that detecting renames is the default behaviour. A new function DiffTreeWithOptions has been added to configure the parameters for the rename detection to control the score threshold, the limit of renames and whether to use similar content detection in the detection.

| | | | | | | | | | | | | | | | | | | | | | Most commits have relatively small messages, so this was never noticeable. However, there are some repositories that have semi-automated messages that can get very large (e.g. github.com/riscv/riscv-clang and its riscv-trunk branch), on the order of 109k lines. Changing from string += to using a bytes.Buffer reduces the time for Commit.Decode for that specific case from 35s to 74ms. Signed-off-by: David Symonds <dsymonds@golang.org>
