We add general code that will archive models that are tied to a specific
Message (such as Reactions and SubMessages). Certain details of the
model are grabbed from a list models_with_message_key, and then used to
create queries that will archive these database tables.
We put Reaction in that list in this commit, and add appropriate tests.
To have archiving of other analogical models (for example SubMessage),
one only needs to make an appropriate entry in the
models_with_message_key list.
test_retention.py had various issues - we opt for keeping its essence
(what should the tests do and verify), but rewriting a lot of it in
order to have more clarity in what's happening there.
We split archive_messages code into two functions: moving to archive and
cleanup. This allows cleaning up the tests - they can call
these functions directly instead of copying several lines of
archive_messages here and there in multiple tests.
test_cross_realm_messages_archiving_two_realm_expired doesn't run the
code path patched in commit 3d1aa98b2ea344fba7fbb2373a37d4cf30f53e08i,
so it can still fail. We apply the analogical change in the test as
in the cited commit.
This is probably a good idea for the production use case, since then
there's some consistency of behavior, and if we extend logging, one
knows exactly which realms were or were not executed before a logged
failure.
This fixes the nondeterministic test failures we've been seeing in CI:
if you use `-id` in that order_by, it happens consistently.
We've been seeing nondeterministic failures in this test suite in CI
that we can't reproduce locally; these print statements should help
track them down.
This is a very old commit for #106, which has been on hiatus for a few
years. It was significantly modified by tabbott to:
* Improve coding style and variable names
* Update mypy annotations style
* Clean up the testing logic
* Update for API changes elsewhere in our system
But the actual runtime code is essentially unmodified from the
original work by Kirill.
It contains basic support for archiving Messages, UserMessages, and
Attachments with a nice test suite. It's still not usable in
production (e.g. it will probably break Reactions, SubMessages, etc.),
but upcoming commits will address that.
The test named `test_archiving_messages_with_attachment`
started flaking recently. We use sets for comparison
instead of lists to avoid arbitrary sorting differences.
We now update all test messages to have a pub_date
of "now" in the setUp() function in TestRetentionLib.
We've seen tests flake on query counts before this
patch. It's not certain that the test flaked due
to time-related glitches, but it seems the most
plausible explanation.
This makes it possible for Zulip administrators to delete messages.
This is primarily intended for use in deleting early test messages,
but it can solve other problems as well.
Later we'll want to play with the permissions model for this, but for
now, the goal is just to integrate the feature.
Note that it saves the deleted messages for some time using the same
approach as Zulip's message retention policy feature.
Fixes#135.
This is a first step towards implementing a message retention policy
feature.
- Add Realm model message_retention_days field to setup
messages expired period for realm.
- Add migration.
- Add tool to get expired messages for each Realm.
- Add tests to cover tool for getting expired messages.
