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
```

avg_time on posts and topics have not been used in a year.
This uses a re-runnable ddl transaction diasabled migration to
drop the column, cause it touchs very high traffic table and may
deadlock
If the feature is enabled, staff members can construct a URL and publish a
topic for others to browse without the regular Discourse chrome.
This is useful if you want to use Discourse like a CMS and publish
topics as articles, which can then be embedded into other systems.
New `duration` attribute is introduced for the `set_or_create_timer` method in the commit aad12822b7 for "based on last post" and "auto delete replies" topic timers.
### UI Changes
If `SiteSetting.enable_bookmarks_with_reminders` is enabled:
* Clicking "Bookmark" on a topic will create a new Bookmark record instead of a post + user action
* Clicking "Clear Bookmarks" on a topic will delete all the new Bookmark records on a topic
* The topic bookmark buttons control the post bookmark flags correctly and vice-versa
Disabled selecting the "reminder type" for bookmarks in the UI because the backend functionality is not done yet (of sending users notifications etc.)
### Other Changes
* Added delete bookmark route (but no UI yet)
* Added a rake task to sync the old PostAction bookmarks to the new Bookmark table, which can be run as many times as we want for a site (it will not create duplicates).
Add TopicUploadSecurityManager to handle post moves. When a post moves around or a topic changes between categories and public/private message status the uploads connected to posts in the topic need to have their secure status updated, depending on the security context the topic now lives in.
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.
This ensures we can very quickly figure out which topics are banners if
a banner is set.
Previously you would have to scan an entire table to find banners
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
* FIX: Do not encode the URL twice
Now that we encode slugs in the server we don't need this anymore.
Reverts fe5na33
* FIX: More places do deal with encoded slugs
* the param is a string now, not a hash
* FIX: Handle the nil slug on /categories
* DEV: Add seeded? method to identity default categories
* DEV: Use SiteSetting to keep track of seeded categories
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.
Currently, the topic is only validated for censored words and should be validated for blocked words as well.
Blocked word validation is now used by both Post and Topic. To avoid code duplication, I extracted blocked words validation code into separate Validator, and use it in both places.
The only downside is that even if the topic contains blocked words validation message is saying "Your post contains a word that's not allowed: tomato" but I think this is descriptive enough.
Previously we relied on side effects to set tracking state correctly
when inviting groups to messages
Also has a minor optimisation in that we use pluck instead of pulling in
full record
Previously we would unconditionally issue an "invited_to_pm" notification
to all non muting users.
New behavior
- Watching and Watching first post get notified
- Tracking get a new "summary" message
- The rest get nothing
This is consistent with topic creation and way clearer
* FEATURE: Allow choice of category when making a PM public
Previously it would default to uncategorized, which was not ideal on
some forums. This gives the staff member more choice about what they'd
like to do.
* Make the optional category more explicit
* Joffrey's feedback
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
Before: 6:05
After: 5:42
Featuring topics for `list/categories` is a very expensive operation that
happened each time we created a topic. This introduces a test only bypass
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
After careful analysis of large data-sets it became apparent that avg_time
had no impact whatsoever on "best of" topic scoring. Calculating avg_time
was a very costly operation especially on large databases.
We have some longer term plans of introducing other weighting that is read
time based into our scoring for "best of" and "top" topics, but in the
interim to stop a large amount of work that is not achieving any value we
are removing the jobs.
Column removal will follow once we decide on a new replacement metric.
If you turn it on now, default all users to approved since they were
previously. Also support approving a user that doesn't have a reviewable
record (it will be created first.)
This also includes a refactor to move class method calls to
`DiscourseEvent` into an initializer. Otherwise the load order of
classes makes a difference in the test environment and some settings
might be triggered and others not, randomly.
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

Previously we would notify on small actions if they were whispers
this inconsistently lead to all sorts of problems including
- collapsed "N replies" after assign
- empty push notifications
New behavior adds an api to explicitly send push notifications as well
if needed: create_notification_alert
* FIX: don't allow inviting more than `max_allowed_message_recipients` setting allows
* add specs for guardian
* user preferences for auto track shouldn't be applicable to PMs (it auto watches on visit)
Execlude PMs from "Automatically track topics I enter..." and "When I post in a topic, set that topic to..." user preferences
* groups take only 1 slot in PM
* just return if topic is a PM
This was not picked up by tests because scheduled jobs are run immediately
and in the current thread (and therefore the current database transaction).
This particular case sometimes occurs inside multiple nested transactions,
so simply moving the offending line outside of the transaction is not enough.
Implemented TransactionHelper, which allows us to use `TransactionHelper.after_commit`
to define code to be run after the current transaction has been committed.
- We spread out bumping through the day, if you are bumping
4 topics then a topic will be bumped every 6 hours
- We add a small, bumping action at the bottom of the post to
denote a topic got bumped
Introduce new patterns for direct sql that are safe and fast.
MiniSql is not prone to memory bloat that can happen with direct PG usage.
It also has an extremely fast materializer and very a convenient API
- DB.exec(sql, *params) => runs sql returns row count
- DB.query(sql, *params) => runs sql returns usable objects (not a hash)
- DB.query_hash(sql, *params) => runs sql returns an array of hashes
- DB.query_single(sql, *params) => runs sql and returns a flat one dimensional array
- DB.build(sql) => returns a sql builder
See more at: https://github.com/discourse/mini_sql
This updates tests to use latest rails 5 practice
and updates ALL dependencies that could be updated
Performance testing shows that performance has not regressed
if anything it is marginally faster now.
- remove inactive user report and replace with posts
- clean up internals so grouping by week happens on client
- when switching periods old report was not destroyed leading to bugs
- calculate trend based on previous interval ... not previous 30 days
- show percentages for mau/dau
- be more careful about utc date usage
- show uniqu and click through rate on search panel
- publish key of report with report so we only load the correct one
- subscribe earlier in channel in case of concurrency issues
* `rescue nil` is a really bad pattern to use in our code base.
We should rescue errors that we expect the code to throw and
not rescue everything because we're unsure of what errors the
code would throw. This would reduce the amount of pain we face
when debugging why something isn't working as expexted. I've
been bitten countless of times by errors being swallowed as a
result during debugging sessions.
This feature can be enabled by choosing a destination for the
`shared drafts category` site setting.
* Staff members can create shared drafts, choosing a destination
category for the topic when it is published.
* Shared Drafts can be viewed in their category, or above the
topic list for the destination category where it will end up.
* When the shared draft is ready, it can be published to the
appropriate category by clicking a button on the topic view.
* When published, Drafts change their timestamps to the current
time, and any edits to the original post are removed.
Also
- Significantly improved search ranking, title is treated most strongly
- Adds tag names to the index
- Run search re-indexer more aggressively
- Re-index topic and all posts on category change
timezone offset was calculated and sent from browser to server, it would be applied on utc time generated from '2013-11-22 5:00' format for example and then sent back to browser which would display it thinking it's UTC time using `moment(utc time)` when it's in fact an UTC time we have offseted with the initial user timezone.
This is impossible to automatically test in the current app state. Easiest reproduction is in live browser after setting your timezone to `America/New_York`, when setting a topic timer to later_today, after save, the time under the topic should be off to something roughly equal +1/-1 hour to your timezone offset.
Figuring out what unread topics a user has is a very expensive
operation over time.
Users can easily accumulate 10s of thousands of tracking state rows
(1 for every topic they ever visit)
When figuring out what a user has that is unread we need to join
the tracking state records to the topic table. This can very quickly
lead to cases where you need to scan through the entire topic table.
This commit optimises it so we always keep track of the "first" date
a user has unread topics. Then we can easily filter out all earlier
topics from the join.
We use pg functions, instead of nested queries here to assist the
planner.
