  v0.32.1 -- the truncation warning promises no ordering Stable

  joeyr released this 2026-08-22 22:41:42 -05:00 | 1 commits to main since this release

  A truncation warning that promised an ordering it does not have. Wording only;
  no behaviour changed.

  Fixed

  • list_messages said "This is the newest 200 of 358" and the window is not the newest
    anything. The cap is uids[-cap:] — the highest UIDs, which is arrival order in that
    label. For INBOX that is close enough to date order that the sentence went unnoticed for
    twelve versions. For the Bin it is the order things were trashed, so a 2009 newsletter
    deleted last week sits above a 2019 one deleted in 2019.

    A connector read that sentence, was asked for the oldest messages in the Bin, and reported
    a pagination bug in this server — reasoning correctly from a claim that was false. A
    read-only census of the live Bin found 358 real matches and zero dropped messages older
    than the window showed, so messages_found was right and the answer happened to be
    right; nothing in the mechanism guarantees the second part.

    The warning now says "Only N of M" — matching icloudmail, which never made the claim —
    and names the question the result cannot answer: not "the oldest N", with before as
    the way to ask it properly.

  • The behaviour is deliberately unchanged. Sorting by date before capping means an
    ENVELOPE fetch for every match in order to discard most of them, and before already
    answers the question. The defect was one word, and one word is what moved.

  Notes

  • The general shape: a warning about incompleteness is read more carefully than the data,
    so an inaccuracy in it is load-bearing. This one turned a correct result into a bug
    report against the server. The test pins the wording rather than the behaviour, which is
    unusual here and is the point.
