We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?
=> true
puts "a #{1} b".frozen?
=> true
puts ("a " + "b").frozen?
=> false
puts (-("a " + "b")).frozen?
=> true
```

* DEV: Update the working tree just once.
`git pull` was effectively doing `git fetch` and `git merge FETCH_HEAD`, and only then we were checking out the desired branch/commit. This change will skip the the merge step.
* DEV: Don't run lefthook in docker_test
I'm not clear why changing only the `wait_for_url` address was necessary and not also the `get` a few lines above, but this change seems to work for me on both literatecomputing.com Groups and a public group.
Checking if all records have been imported uses a temp table in PostgreSQL. This fails when pgbouncer is used unless the temp table is created inside a transaction.
* Detects mostly all attachments and it's a lot faster
* Parses user properties in Ruby instead of the DB, because that's less errorprone
* Imports user avatars
* Imports topic views by users
* Better handling of quotes and YouTube links
* Adds ability to map forums to categories and tags as well as ignore forums.
* Fixes regular expression for detecting attachments in posts.
* Handles "remote attachments" 😮 by inserting a link.
* Imports view counts for topics.
* Handles incorrect references of parent posts.
* Better handling of quotes.
* Finds a lot more attachments by trying to replace various Unicode characters in filenames.
* Customizable email subject prefixes to remove "Re" and "Fwd" as well as localized prefixes.
* Configuration option for prefixes like [FOO] or (BAR) which can be replaced with tags during import.
* Bugfix: Import script might have skipped some users due to missing ORDER BY.
Posts without a user probably shouldn't happen unless there was some direct database tampering, but data like that has been seen in the wild.
The importer will assign those posts to the "system" user.
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
This is not used in core or official plugins, and has been printing a deprecation notice since v2.3.0beta4. All OpenID 2.0 code and dependencies have been dropped. The user_open_ids table remains for now, in case anyone has missed the deprecation notice, and needs to migrate their data.

With this change the script:
* Actually removes original large-sized images
* Doesn't save processed files if their size has increased
* Prevents inconsistent state
We pick the first topic with 30 responses as our bench topic.
Previously we simply picked the last topic, but hand no guarantee on ordering.
This also attempts to correct previous runs of the bench.
The following methods have long been deprecated in ruby due to flaws in their implementation per http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-core/29293?29179-31097:
URI.escape
URI.unescape
URI.encode
URI.unencode
escape/encode are just aliases for one another. This PR uses the Addressable gem to replace these methods with its own encode, unencode, and encode_component methods where appropriate.
I have put all references to Addressable::URI here into the UrlHelper to keep them corralled in one place to make changes to this implementation easier.
Addressable is now also an explicit gem dependency.
We like to stay as close as possible to latest with rubocop cause the cops
get better.
This update required some code changes, specifically the default is to avoid
explicit returns where implicit is done
Also this renames a few rules
This is a bottom up rewrite of Discourse cache to support faster performance
and a limited surface area.
ActiveSupport::Cache::Store accepts many options we do not use, this partial
implementation only picks the bits out that we do use and want to support.
Additionally params are named which avoids typos such as "expires_at" vs "expires_in"
This also moves a few spots in Discourse to use Discourse.cache over setex
Performance of setex and Discourse.cache.write is similar.
Discourse.cache is a more consistent method to use and offers clean fallback
if you are skipping redis
This is part of a larger change that both optimizes Discoruse.cache and omits
use of setex on $redis in favor of consistently using discourse cache
Bench does reveal that use of Rails.cache and Discourse.cache is 1.25x slower
than redis.setex / get so a re-implementation will follow prior to porting
`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.

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 removes all uses of both `send` and `public_send` from consumers of
SiteSetting and instead introduces a `get` helper for dynamic lookup
This leads to much cleaner and safer code long term as we are always explicit
to test that a site setting is really there before sending an arbitrary
string to the class
It also removes a couple of risky stubs from the auth provider test
