jcoffey-dev is traveling from Thursday 1 October through Sunday 4 October. Issues and pull requests are welcome, and will get an answer after that. Thanks for your patience.
inbuxa:LegalHold/get answers accountsCovered, itemsHeld and sizeHeld
when asked: the accounts a hold reaches now (deleted ones it keeps
included) and the archived items it keeps, with their size. Worked out
in one pass over accounts and archive, only for requests that name them.
Held items stay out of the user's quota, as all archived copies do
(LH-9).
Destroying a held account removes the login, as offboarding needs, but
keeps its data as a deleted account with no expiry, whether or not
undelete keeps accounts; its addresses stay reserved and its holds name
it from then on. Destroy-now refuses it, and its DestroyAccount task
defers itself while it's held or its time hasn't come. Holds placed or
released later freeze or free kept accounts in the same settle pass,
with 30 days' grace after the last release (LH-8, LH-10).
Placing or widening a hold freezes what's already archived in its scope
and range, its old deadline noted; releasing one gives each item no other
hold covers that deadline back, or release plus 30 days if later. One
pass over the archive does both and changes nothing twice (LH-6, LH-10,
LH-11). A held archived item can't be destroyed; restoring still can,
and the hold is named only to callers who may see holds (LH-7). Audit
records about a held account survive the purge (AU-7).
Fixes the daily clean-up of expired archived items (UD-13), which never
found any: the registry's unfiltered query reads an all-ids index that
archived items aren't in. Items are now walked account by account, kept
deleted accounts included. Expired items were still removed whenever
their account's archive was read.
Every way of deleting mail (JMAP, IMAP EXPUNGE, POP3, mailbox removal,
Trash emptying) and Sieve scripts, events, contacts and files now asks
how the account's deletions are kept: a hold keeps them with no expiry
(archivedUntil 9999-12-31), even with undelete off; otherwise undelete's
period applies as before (LH-4).
A hold's date range decides by the item's own date (LH-3). Mail is noted
as held at deletion and settled when it's archived, once its received
date is known; outside the range it gets undelete's deadline or isn't
kept. Events go by their start, with a day's slack for time zones;
recurring events, contacts, files and scripts are held whole.
A groupware item's note now stays until its archive succeeds, and a
failure retries the task instead of being logged and lost (LH-5).
A hold reaches an account by name, through any of its addresses'
domains, its groups or its tenant, as they are now, so an account added
to a held domain later is held too. An account that leaves a held
domain, group or tenant stays held: the registry write hook adds it to
the hold by name on every account change, whoever makes it (LH-2).
Server::holds_on answers for the deletion paths, from the store each
time so a hold binds every node at once.
