Subject: [PATCH 00/15] use RENAME_NOREPLACE on Linux 3.15+
Date: Thu, 21 Oct 2021 21:10:17 +0000	[thread overview]
Message-ID: <20211021211032.22666-1-e@80x24.org> (raw)

What started off as a trivial, "something-to-do-before-bedtime"
change several days ago (15/15) ended up forcing me to fix
various hard-to-reproduce race conditions around Maildirs.

Eventually, `schedtool -a 0x1 -e ...' helped me reproduce
some races more easily (but still not with 100% reliability).

t/lei-{watch,auto-watch,export-kw}.t should all be more
reliable, now.

There's also several other minor fixes I found along the way...

Eric Wong (15):
  t/lei-{auto-watch,export-kw}: extra diagnostics on failure
  t/lei-import-maildir: rename fix (SR -> RS)
  t/lei-p2q: extra diagnostics
  lei/store: check for any unexpected process death
  lei note-event: drop unnecessary eval guard
  lei note-event: wq_io_do => wq_do
  lei_search: try harder to associate "lei index"-ed messages
  watch: check for {quit} before IDLE
  watch: remove redundant signal mask manipulation
  doc: lei-overview: add CAVEATS section
  lei note-event: clear_src on ENOENT
  dir_idle: treat IN_MOVED_FROM as a gone event
  lei: no Perl FileHandle for `undef' w/ ECONNRESET
  lei_mail_sync: mv_src: use transaction, check UNIQUE
  lei: use RENAME_NOREPLACE on Linux 3.15+
