`FileUtils.cd` and `Dir.chdir` cause the working directory to change for the entire process. We run sidekiq jobs, hijacked requests and deferred jobs in threads, which can make working directory changes have unintended side-effects.
- Add a rubocop rule to warn about usage of Dir.chdir and FileUtils.cd
- Added rubocop:disable for scripts used outside the app
- Refactored code using cd to use alternative methods
- Temporarily skipped the rubocop check for lib/backup_restore. This will require more complex refactoring, so I will create a separate PR for review
Doing .pluck(:column).first is a very common pattern in Discourse and in
most cases, a limit cause isn't being added. Instead of adding a limit
clause to all these callsites, this commit adds two new methods to
ActiveRecord::Relation:
pluck_first, equivalent to limit(1).pluck(*columns).first
and pluck_first! which, like other finder methods, raises an exception
when no record is found
The script will now correct all width/height and thumbnail_width/thumbnail_height properties of all the uploaded images.
The script now uses width * height to filter out all unaffected images.
Also handled the case where a downsized image was already an uploaded record.
These scripts are somewhat rough but I needed them to help debug a memory
leak we have noticed in rails 6.
The biggest object script finds all the biggest objects we have in memory
after boot.
The test memory leak runs a very simple iteration through all multisites
and observed memory.
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.
Trying to automate the login into a Google account is quite hard. This makes the crawler use the content of a cookies.txt file instead. It also removes a couple of deprecation warnings and adds some color to the output.
This is a temporary workaround for the issue in https://github.com/rails/rails/pull/36949
Discussing a proper fix in Rails with the Rails team.
Prior to this fix we were spinning up a thread every time we closed a connection
to the db.
* REFACTOR: Rename SiteSetting.disable_edit_notifications to disable_system_edit_notifications
- The older name could cause some confusion because the setting does not disable all edit notifications, only system ones.
* FIX: Add frozen_string_literal: true in the migration
* DEV: Deprecate 'disable_edit_notifications'
This also corrects FileHelper.download so it supports "follow_redirect"
correctly (it used to always follow 1 redirect) and adds a `validate_url`
param that will bypass all uri validation if set to false (default is true)
* FEATURE: Add attachment support to XenForo importer
If `ATTACHMENT_DIR` is provided, importer will scan each imported post
for `[GALLERY]` and `[ATTACH]` tags, attempt to import the referenced files
as Discourse uploads and replace the tags with Discourse markup.
References to files which cannot be imported are stripped.
NOTE: This only imports attachments which are referenced in imported
posts. Any XenForo media or files which are not referenced in any post
using `[ATTACH]` or `[GALLERY]` tags will not be imported. The goal is to
ensure that we don't have posts with missing images and unsightly
markup, NOT to ensure that all attachments are migrated.
