DEV: Replace #pluck_first freedom patch with AR #pick in core (#19893)
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.

There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.

FEATURE: Cook drafts excerpt in user activity (#14315)
The previous excerpt was a simple truncated raw message. Starting with
this commit, the raw content of the draft is cooked and an excerpt is
extracted from it. The logic for extracting the excerpt mimics the the
`ExcerptParser` class, but does not implement all functionality, being
a much simpler implementation.

The two draft controllers have been merged into one and the /draft.json
route has been changed to /drafts.json to be consistent with the other
route names.

FIX: Update draft count after creating a post (#13884)
When a post is created, the draft sequence is increased and then older
drafts are automatically executing a raw SQL query. This skipped the
Draft model callbacks and did not update user's draft count.

I fixed another problem related to a raw SQL query from Draft.cleanup!
method.

FEATURE: Show draft count in user menu and activity (#13812)
This commit adds the number of drafts a user has next to the "Draft"
label in the user preferences menu and activity tab. The count is
updated via MessageBus when a draft is created or destroyed.

FEATURE: Allow users to save draft and close composer (#12439)
We previously included this option conditionally when users were replying
or creating a new topic while they had content already in the composer.

This makes the dialog always include three buttons:
  - Close and discard
  - Close and save draft for later
  - Keed editing

This also changes how the backend notifies the frontend when there is
a current draft topic. This is now sent via the `has_topic_draft`
property in the current user serializer.

FIX: properly ban non human users from draft system
Previously we had a partial fix in place where non human users
were not allowed draft sequences, this left edges around where non
human users asked for drafts yet had none.

For example system could already have a few drafts in place.

This also removes and extensibility point we added that is not in use

FIX: saving drafts unconditionally increases sequence
Previously we only changed sequence on ownership change, this
cause a race condition between tabs where user could type for a
long time without being warned of an out of date draft.

This change is a radical change and we should watch closely.

Code was already in place to track sequence on the client so no
changes are needed there.

Rafael dos Santos Silva 226d81fcc5 FIX: Fix a PostgreSQL error when a draft was concurrently created
Moves the new draft creation concurrency handling to PostgreSQL
so the database doesn't error out when the draft is being created
by multiple backends.

Also removes `retry_not_unique` parameter from Draft#set` which is
not called anywhere.

Also fixes a draft update not bumping the `updated_at` column.

FIX: Typo on draft save 2020-03-11 12:12:28 -03:00
Sam Saffron 34ede90927 FIX: under rare conditions saving a new draft could error temporarily
Under rare conditions due to bad HTTP timing and so on a draft could be
set at the exact same time from 2 unicorn workers.

When this happened and all the stars aligned, one of the sets would win
and the other would raise an error.

This transparently handles the situation without adding any cost to the
draft system.

The alternative is to add a distributed mutex, tricky DB transaction or handle
the error in the controller. However this seems like a reasonable way to
work around a pretty big edge case.

Sam Saffron deec2cf578 FIX: drafts are unique by draft_key and user_id
Previously our index was non unique, causing situations where a user could
have multiple drafts stored in the table for the same exact entity.

This does not properly reflect reality and needed to change as in certain
cases duplicate drafts could be created causing internal data inconsistency

Sam Saffron 70c6831125 PERF: add a filtered index for banners
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

Sam Saffron c5e67726fd FIX: under some conditions draft would say it was saving when not
This is a major change to draft internals. Previously there were quite a
few cases where the draft system would say "draft saved", when in fact
we just skipped saving.

This commit ensures the draft system deals with draft ownership handover in
a predictable way.

For example:

- Window 1 editing draft
- Window 2 editing same draft at the same time

Previously we would allow window 1 and 2 to just fight on the same draft
each window overwriting the same draft over an over.

This commit introduces an ownership concept where either window 1 or 2 win
and user is prompted on the loser window to reload screen to correct the issue

This also corrects edge cases where a user could have multiple browser windows
open and posts in 1 window, later to post in the second window. Previously
drafts would break in the second window, this corrects it.

Daniel Waterworth 55a1394342 DEV: pluck_first
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

Sam Saffron cb0443792b DEV: correct revision debouncer for backup draft
We were debouncing on update_at which we kept on pushing forward, this
was leading to not enough revisions.

Sam Saffron f5d1aff8dd FEATURE: experimental hidden setting for draft backups
Under exceptional situations the automatic draft feature can fail.

This new **hidden, default off** site setting
`backup_drafts_to_pm_length` will automatically backup any draft that is
saved by the system to a dedicated PM (originating from self)

The body of that PM will contain the text of the reply.

We can enable this feature strategically on sites exhibiting issues to
diagnose issues with the draft system and offer a recourse to users who
appear to lose drafts. We automatically checkpoint these drafts every 5
minutes forcing a new revision each 5 minutes so you can revert to old
content.

Longer term we are considering automatically enabling this kind of feature
for extremely long drafts where the risk is really high one could lose
days of writing.

Sam 5f64fd0a21 DEV: remove exec_sql and replace with mini_sql
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
