This commit introduces a hidden `s3_inventory_bucket` site setting which
replaces the `enable_s3_inventory` and `s3_configure_inventory_policy`
site setting.
The reason `enable_s3_inventory` and `s3_configure_inventory_policy`
site settings are removed is because this feature has technically been
broken since it was introduced. When the `enable_s3_inventory` feature
is turned on, the app will because configure a daily inventory policy for the
`s3_upload_bucket` bucket and store the inventories under a prefix in
the bucket. The problem here is that once the inventories are created,
there is nothing cleaning up all these inventories so whoever that has
enabled this feature would have been paying the cost of storing a whole
bunch of inventory files which are never used. Given that we have not
received any complains about inventory files inflating S3 storage costs,
we think that it is very likely that this feature is no longer being
used and we are looking to drop support for this feature in the not too
distance future.
For now, we will still support a hidden `s3_inventory_bucket` site
setting which site administrators can configure via the
`DISCOURSE_S3_INVENTORY_BUCKET` env.
This commit updates `S3Inventory#files` to ignore S3 inventory files
which have a `last_modified` timestamp which are not at least 2 days
older than `BackupMetadata.last_restore_date` timestamp.
This check was previously only in `Jobs::EnsureS3UploadsExistence` but
`S3Inventory` can also be used via Rake tasks so this protection needs
to be in `S3Inventory` and not in the scheduled job.
After restoring a backup it takes up to 48 hours for uploads stored on S3 to appear in the S3 inventory. This change prevents alerts about missing uploads by preventing the EnsureS3UploadsExistence job from running in the first 48 hours after a restore. During the restore it deletes the count of missing uploads from the PluginStore, so that an alert isn't triggered by an old number.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
