Instance Method Details

#diff_blobs(blob_pairs, diff_mode: DIFF_MODES[:unspecified], whitespace_changes: WHITESPACE_CHANGES[:unspecified], patch_bytes_limit: 0) ⇒ GitalyClient::DiffBlobsStitcher

Requests diffs between blob pairs via Gitaly’s DiffBlobs RPC using blob_pairs field.

Parameters:

  • blob_pairs (Array<Gitaly::DiffBlobsRequest::BlobPair>) —

    Array of blob ID pairs to diff

  • diff_mode (Symbol) (defaults to: DIFF_MODES[:unspecified]) —

    Diff output mode (:unspecified, :word)

  • whitespace_changes (Symbol) (defaults to: WHITESPACE_CHANGES[:unspecified]) —

    Whitespace handling (:unspecified, :ignore_spaces, :ignore_all_spaces)

  • patch_bytes_limit (Integer) (defaults to: 0) —

    Maximum patch size in bytes (0 = unlimited)

Returns:

#diff_blobs_with_raw_info(raw_info, diff_mode: DIFF_MODES[:unspecified], whitespace_changes: WHITESPACE_CHANGES[:unspecified], patch_bytes_limit: 0) ⇒ GitalyClient::DiffBlobsStitcher

Requests diffs between blob pairs via Gitaly’s DiffBlobs RPC using raw_info field. More efficient for large batches of files compared to blob_pairs approach.

Parameters:

  • raw_info (Array<Gitaly::ChangedPaths>) —

    Array of changed path information

  • diff_mode (Symbol) (defaults to: DIFF_MODES[:unspecified]) —

    Diff output mode (:unspecified, :word)

  • whitespace_changes (Symbol) (defaults to: WHITESPACE_CHANGES[:unspecified]) —

    Whitespace handling (:unspecified, :ignore_spaces, :ignore_all_spaces)

  • patch_bytes_limit (Integer) (defaults to: 0) —

    Maximum patch size in bytes (0 = unlimited)

Returns:
