@andrwng The build seems to be failing. |
CONFLICT: - removed windowed compaction bit After a delete-records request, when collecting segments to determine the next upload candidate, we could end up trying to build an upload candidate with a start offset lower than the local log. Consider the following sequence: - Segment [0, 200)[200-400) are merge compacted ==> [0, 400). - Delete records ==> start offset is now 1. - Reupload our first compacted segment so we look up offset 1, realign the collection start target to a remote segment 200. - We collect segments starting from 200, getting [0, 400). - Collector gets realigned to 0 since it's the first segment. The collector now thinks it should be uploading [0, 400). - In building the upload candidate, we try to translate the range start and fail because the range start 0 is lower than the translation range start 1. This fixes this sequence to return [200, 400) as the start of the upload candidate. (cherry picked from commit b26d1e9)
