<198982749+Copilot@users.noreply.github.com> Date: Sun, 25 Jan 2026 20:43:27 +0000 Subject: [PATCH 11/22] fix: Change all callbacks to TRUE=stop, FALSE=continue MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Updated all callback handlers and tests to use the consistent convention from the hand-rolled implementations: - R callback returns TRUE → C returns IGRAPH_STOP → terminate/stop - R callback returns FALSE → C returns IGRAPH_SUCCESS → continue This matches the old hand-rolled BFS/DFS behavior and is now applied uniformly across all callback functions: - BFS callbacks - DFS callbacks - Motifs callbacks - Cliques callbacks - Cycles callbacks - Isomorphism callbacks All tests updated accordingly to use FALSE for continuation and TRUE for termination.
