On forums with a large amount of posts when a user had a bookmark in the topic, PostgreSQL was using an inefficient query plan to fetch the first post of the topic. When running this ActiveRecord query:
```
topic.posts.with_deleted.where(post_number: 1).first
```
The following query plan was produced:
```
Limit (cost=0.43..583.49 rows=1 width=891) (actual time=3850.515..3850.515 rows=1 loops=1)
-> Index Scan using posts_pkey on posts (cost=0.43..391231.51 rows=671 width=891) (actual time=3850.514..3850.514
rows=1 loops=1)
Filter: ((topic_id = 160918) AND (post_number = 1))
Rows Removed by Filter: 2274520
Planning time: 0.200 ms
Execution time: 3850.559 ms
(6 rows)
```
The issue here is the combination of ORDER BY and LIMIT causing the ineficcient Index Scan using posts_pkey on posts to be used. When we correct the AR call to this:
```
topic.posts.with_deleted.find_by(post_number: 1)
```
We end up with a query that still has a LIMIT but no ORDER BY, which in turn creates a much more efficient query plan:
```
Limit (cost=0.43..1.44 rows=1 width=891) (actual time=0.033..0.034 rows=1 loops=1)
-> Index Scan using index_posts_on_topic_id_and_post_number on posts (cost=0.43..678.82 rows=671 width=891) (actua
l time=0.033..0.033 rows=1 loops=1)
Index Cond: ((topic_id = 160918) AND (post_number = 1))
Planning time: 0.167 ms
Execution time: 0.072 ms
(5 rows)
```
This query plan uses the correct index, `Index Scan using index_posts_on_topic_id_and_post_number on posts`. Note that this is only a problem on forums with a larger amount of posts; tiny forums would not notice the difference. On large forums a query for a topic that takes 1s without a bookmark can take 8-30 seconds, and even end up with 502 errors from nginx.
* PERF: we don't need to use a huge image to test thumbnails
Generating images with 5000x5000 dimensions is an expensive operation.
Using smaller images reduce the time of model spec from 11s to 3s and integration spec from 6s to 2s.
When plugin spec is evaluated for the first time, it took 30 seconds to run:
```
rm -rf tmp/* && LOAD_PLUGINS=1 be rspec ./plugins/discourse-solved/spec/requests/topics_controller_spec.rb
```
Applying sprocket patch in test environment solves that issue
New version of Thunderbird email client reimplemented PGP support. Now the following attachments are added by default, if email signatures are enabled:
* OpenPGP_0x(pgp key id).asc
* OpenPGP_signature(.asc)
The last one has `name="OpenPGP_signature.asc"` in `Content-Type` but `filename="OpenPGP_signature"` (without extension) in `Content-Disposition: attachment`.
Since both the key and the signature have proper MIME types, filter them by default.
Documenting a few more endpoints so that our api docs can be
automatically generated. Made a couple other minor changes, like
including the "OK" example for our default success response.
Resending an invite moved the expire date in the future, but did not
invalidate it. For example, if an invite was sent to an email,
invalidated and then resent, it would still be left invalidated.

* FEATURE - Add SiteSettings to control JPEG image quality
`recompress_original_jpg_quality` - the maximum quality of a newly
uploaded file.
`image_preview_jpg_quality` - the maximum quality of OptimizedImages
* FEATURE: allow category group moderators to edit posts
If the `enable_category_group_moderation` SiteSetting is enabled, posts should be editable by those belonging to the appropraite groups.
Trying to include this attribute when topic_user is nil causes an error when visiting a topic as anon. Additionally, we don't display the slow mode banner for these users.
Showing this button is confusing for sites which are using external authentication. Clicking 'log in' already pops up the login modal, which includes a forgot password link when appropriate.
This PR introduces a feature that will detect a date inside the post that a user is bookmarking, and offer that date as an option in the bookmark modal.
The logic is that we get the first date/time detected in the post. If it does not have a time, just a date, then we default to 8:00am for the time.
Previously if a onebox timed out we would not present the users in the log
with any information regarding the onebox. This makes it very difficult to
debug.
This adds url/topic/user in the debugging output.
`max-width: 50%; max-height: 400px;` is a good fallback, however, if width and height are given and are smaller than fallback - we should persist that smaller size.
Our Email::Sender class accepts an optional user argument, which is used to create a PostReplyKey record when present. This record is used to sub out the %{reply_key} placeholder in the Reply-To mail header, so if we do not pass in the user we get a broken Reply-To header.
This is especially problematic in the IMAP group SMTP situation, because these emails go to customers that we are replying to, and when they reply to us the email bounces! This fixes the issue by passing user to the Email::Sender when sending a group_smtp email but there is still more to do in another PR.
This Email::Sender optional user is a bit of a footgun IMO, especially because most of the time we use it there is a user we can source. I would like to do another PR for this after this one to make the parameter not optional, so we don't end up with these reply issues down the line again.
