XR: make ENQUEUE-TD-DELETION always take a berth and timestamp (!12) · Merge requests · eta / intertube

eta requested to merge eta/enqueue-deletion-tweaks into master May 28, 2023

#44 (closed) has some weird sequence that doesn't make any sense to me. Let's attempt to fix this by making sure that we don't ever fake cancellation messages: instead, we should just insert them with the originally given timestamp.
That way, if we do get a cancel and then an interpose, it shouldn't be a problem -- the interpose, if it has a timestamp greater than the cancel, should either cause the cancel to be ignored or delete it (using the already-established mechanisms for when two things have the same universal time).
Maybe this will result in a fix for #44 (closed)? I don't quite understand what's going on there.
(We also never try to rescue a train into itself in non-SMART areas, and do some other minor tweaks.)
