need tests for interactions with older-version mailboxes #2

Open elliefm opened 8 years ago

elliefm commented 8 years ago

I imagine these working something like:

repository contains zipped up old-version test mailboxes
extract these into the user.cassandane mailbox
carefully reconstruct it so they're linked up correctly but without upgrading the mailbox version
do various tests -- select, move/copy messages in and out, etc etc
reconstruct upgrade test

Can we create old version mailboxes programmatically at test time, or will someone need to install and configure old builds of cyrus in order to produce zips of some mailboxes to add to the repo?

Maybe reconstruct -V could be used to downgrade a mailbox on the fly, avoiding the need for static test data

Had a specific need for testing replication of old versions, so off we go. Work in progress here: https://github.com/cyrusimap/cassandane/compare/master...elliefm:old-version-mailboxes

The static data it uses at the moment was just generated with "reconstruct -V" from a current version of Cyrus (which might not really be the same thing). We really ought to try and replace it with mailboxes obtained from legit old versions, but that's quite a bit more work so it can wait for now

The first stage of this functionality is now on master, and the first set of tests (replication to old mailboxes) too: https://github.com/cyrusimap/cassandane/commit/e6ca602833d874876d8d549641d6396cafa85a26

Still need:

[ ] test data for a version 10 mailbox with zero'd out guids
[ ] test data built from proper old versions rather than reconstruct -V
