Sam Saffron 19e3b3b1bc PERF: speed up topic poster lookups
During profiling looking up topic users popped up as a hot path, this
change more than halved the amount of work it does

It reduces object allocations and method calls and avoids repeate translation
of common terms

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
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

Sam Saffron 0a5a6dfded DEV: stop mutating inputs as a side effect
We had quite a few cases in core where inputs are being mutated as a side
effect of calling a method.

This handles all the cases where specs caught this.

Mutating inputs makes code harder to reason about. Eg:

```
frog = "frog"
jump(frog)
puts frog
"fly" # ?????
```

This commit is part of a followup commit that adds # frozen_string_literal
to all our specs.

Sam Saffron 0c35b8b420 FEATURE: add suggested_topics_unread_max_days_old
This new site setting determines the maximum age of unread topics in
suggested. By default if you have any unread topics older than 90 days
they will be omitted from suggested.

This change was added for 2 reasons:

1. A performance safeguard, some users tend to collect a huge amount of
read state so it becomes super expensive to find unread

2. People who collect a large amount of unread are much more interested in
recent unread topics vs ancient unread topics, this makes suggested more
relevant

Also, this is a minor speed up for tests cause 3 expensive tests became 1.

Sam Saffron 0744d2ef73 PERF: speed up suggested unread
Previously we tried using a sub-query which has some terrible performance
implications, by adding 1 extra query we can eliminate the PG issue

A join to user_stats also is prone to the same slowdown
2019-04-05 15:55:29 +11:00
Sam Saffron 5f896ae8f7 PERF: Keep track of when a users first unread is
This optimisation avoids large scans joining the topics table with the
topic_users table.

Previously when a user carried a lot of read state we would have to join
the entire read state with the topics table. This operation would slow down
home page and every topic page. The more read state you accumulated the
larger the impact.

The optimisation helps people who clean up unread, however if you carry
unread from years ago it will only have minimal impact.

Sam 94b8ba4f8f FIX: remove slow platform detection from server side
Historically due to https://meta.discourse.org/t/why-is-discourse-so-slow-on-android/8823
we decreased page sizes of both home page and topic page on android by half.

This was done on the server side and as a side effect and caused page sizes on android
to mismatch between Android and non Android.

Unfortunately about a year ago googlebot started pretending it is Android,
this cause Google to start indexing pages as what android would see. So
it saw double the amount of pages in the index as what exists on desktop.
This in turn caused double the amount of indexing work and a large amount
of broken links on long topics.

This fix removes all special behavior which is no longer needed due to
other performance work in Discourse including raw handlebars on home page
and virtual dom on topic pages.

I tested we do not need this on Blu Advance 5.0 it has 1.3 GHZ mediatec mt6580
This phone retails for around $50 USD.

If we decide long term that we want any hacks like this we will shift them
to the client side. It can just hold data in memory without rendering.

FIX: Only hide shared draft topics from `latest` (#6737)
Previously we were hiding them from all topic lists, which can result in
topics being "stuck" in an unread state with no easy way to clear them.

UX: Make shared drafts behaviour consistent for non-staff users (#6734)
This makes it easier to diagnose the problem when a public category
is set as the 'shared drafts category'. Doing this is not recommended.

Sam e17a13ce19 FEATURE: additional "related messages" section

has a dedicated section called "related messages"

Sam 9933059426 FEATURE: push related PMs to take first 3 slots
Previously the related PMs were last meaning you would have to work through
all unread to see them.

Also amends it so it either asks for related by group OR user not both.

David Taylor 9bf522f227
FEATURE: Mixed case tagging (#6454)
- By default, behaviour is not changed: tags are made lowercase upon creation and edit.

- If force_lowercase_tags is disabled, then mixed case tags are allowed.

- Tags must remain case-insensitively unique. This is enforced by ActiveRecord and Postgres.

- A migration is added to provide a `UNIQUE` index on `lower(name)`. Migration includes a safety to correct any current tags that do not meet the criteria.

- A `where_name` scope is added to `models/tag.rb`, to allow easy case-insensitive lookups. This is used instead of `Tag.where(name: "blah")`.

- URLs remain lowercase. Mixed case URLs are functional, but have the lowercase equivalent as the canonical.

Robin Ward b9abd7dc9e FEATURE: Shared Drafts
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.
