# HG changeset patch # User Daniel Ploch # Date 1625251453 25200 # Node ID 00ae1fb6c4591818e65d8fa2a27ddcb930dc711a # Parent 57bdecf4322ca0d901f17955c7c8372cdc310593 cmdutil: fix newandmodified file accounting for --interactive commits `originalchunks` is a misleading name, because it only contains header objects, which are flattened to selected hunks by the filter function. As such, `chunks not in originalchunks` is always True and misleading, because hunk objects never compare equal to header objects. This change fixes the internal naming and removes the useless parameter from the method. This change also fixes issue6533, by considering the filtered headers, rather than the hunks, when determining new and modified files. If a file is renamed + edited, and the edited hunks are deselected (but the file is not), the filtered chunks will contain a header for the file (because it's .special()) but but no hunks.
