Convert all IMAP logging to write to a database table for easier inspection. These logs are cleaned up daily if they are > 5 days old.
Logs can easily be watched in dev by setting DISCOURSE_DEV_LOG_LEVEL=\"debug\" and running tail -f development.log | grep IMAP
* Fixed an issue I introduced in the last PR where I am just archiving everything regardless of whether it is actually archived in Discourse man_facepalming
* Refactor group list_mailboxes IMAP code to use providers, add specs, and add provider code to get the correct prodivder
Adds a imap_group_id column to IncomingEmail to deal with an issue where we were trying to update emails in the mailbox, calling IncomingEmail.where(imap_sync: true). However UID and UIDVALIDITY could be the same across accounts. So if group A used IMAP details for Gmail account A, and group B used IMAP details for Gmail account B, and both tried to sync changes to an email with UID of 3 (e.g. changing Labels), one account could affect the other. This even applied to Archiving!
Also in this PR:
* Fix error occurring if we do a uid_fetch and no emails are returned
* Allow for creating labels within the target mailbox (previously we would not do this, only use existing labels)
* Improve consistency for log messages
* Add specs for generic IMAP provider (Gmail specs still to come)
* Add custom archiving support for Gmail
* Only use Message-ID for uniqueness of IncomingEmail if it was generated by us
* Various refactors and improvements
Unicorn uses the USR1 to indicate that log files should be reopened. This commit implements the same functionality for our forked sidekiq workers:
- USR1 is intercepted in the unicorn master, and re-issued to all child processes
- USR1 is trapped in the sidekiq processes, and `Unicorn::Util.reopen_logs` is used to re-open log files
Previously we had many places in the app that called `hostname` to get
hostname of a server. This commit replaces the pattern in 2 ways
1. We cache the result in `Discourse.os_hostname` so it is only ever called once
2. We prefer to use Socket.gethostname which avoids making a shell command
This improves performance as we are not spawning hostname processes throughout
the app lifetime
I introduced DemonBase because I had got some conflict between `demon/base.rb` and `jobs/base.rb`, however, to not rename base class, it is possible to use regex on absolute path in Zeitwerk custom inflector.
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.
This reverts commit e805d44965.
We now have mechanisms in place to ensure heartbeat will always
be scheduled even if the scheduler is overloaded per: 098f938b
* FIX: Heartbeat check per sidekiq process
* Rename method
* Remove heartbeat queues of previous bootups
* Regis feedback
* Refactor before_start
* Update lib/demon/sidekiq.rb

* Expire redis keys after 3600 seconds
* Don't use redis to store the list of queues
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
This commit introduces an ultra low priority queue for post rebakes. This
way rebakes can never interfere with regular sidekiq processing for cases
where we perform a large scale rebake.
Additionally it allows Post.rebake_old to be run with rate_limiter: false
to avoid triggering the limiter when rebaking. This is handy for cases
where you want to just force the full rebake and not wait for it to trickle
This ensures that unicorn master forks of sidekiq run with a lower priority
than the webs. It means that a busy sidekiq is less likely to impact web
performance
This commit introduces 3 queues for sidekiq
"critical" for urgent jobs (weighted at 4x weight)
"default" for standard jobs(weighted at 2x weight)
"low" for less important jobs
"critical jobs"
Reset Password emails has been seperated to its own job
Heartbeat which is required to keep sidekiq running
Test email which needs to return real quick
"low priority jobs"
Notify mailing list
Pull hotlinked images
Update gravatar
"default"
All the rest
Note: for people running sidekiq from command line use
bin/sidekiq -q critical,4 -q default,2 -q low
After fork SiteSettings was not getting a new process id,
causing site settings not to refresh properly in unicorn
This code also centralizes the logic
