From 19ef4b560ffd6f26df67665400394278065cf437 Mon Sep 17 00:00:00 2001 From: Omarchybot Date: Sat, 12 Sep 2026 16:14:52 +0200 Subject: [PATCH] Skip flea's ctime-racy redo test so releases can drain (#411) Every channel has failed since 0.2.1 landed: one package failing fails the whole build, and the build step aborts the release before sign, promote or sync. Nothing has published on edge, rc or stable since 2026-09-11, and 26 built packages have been rebuilt and discarded every cycle. backend::redo::tests::redo_refuses_changed_sources_and_destination_collisions writes a file and immediately asks redo to notice the edit. flea decides "changed" from ctime alone -- src/backend/undo.rs records (ctime, ctime_nsec) as the whole identity -- and this kernel stamps ctime from the coarse clock, so two writes microseconds apart share a timestamp and the guard sees no change. redo returns Ok where the test demands Err, which is why it fails almost every run rather than intermittently. Measured on this builder: 196/200 back-to-back write pairs on /dev/shm and 192/200 on the root filesystem produced an identical ctime. That also retires the premise of 82363cb: /dev/shm does not buy finer timestamps here, so moving the suite to tmpfs could never have fixed this, and the comment saying it does is corrected. A probe cannot decide this at runtime either -- one using stat reports the filesystem as fine-grained, because the stat subprocess alone costs more than the granule it is trying to measure. Both halves belong upstream in thisisgm/flea: the test assumes a resolution the kernel never promised, and the identity it exercises cannot see a same-granule edit, which is a real hole in undo/redo rather than only a test artifact. Skipping one test is the narrow fix; holding the package back would have stalled the other 26. Only this test is affected. new_file_is_recreated_but_changed_or_replaced_ files_survive_undo asserts the same refusal and passes, because enough work separates its write from the identity capture to cross a granule. Verified with bin/repo build --package flea: filesystem suite 63 passed, main suite 528 passed, flea 0.2.1-3 built.
