I do that too. :-) Mine is probably not the most efficient method, but most of the time I record with -M, and use output lines (either turning on logging, like RUST_LOG=debug, or adding printfs showing details of documents/elements) to orient myself when debugging. Doing a "rr replay -g <nnnn>" for a particular output line will break in the process that printed out that line. (I've never had to debug something under rr that involves the interaction between processes.) _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
