If a user copies a gif from a website into their clipboard and then
tries to paste it into the Discourse composer, we would only paste a
static single frame of the original gif. This happens because the
browser doesn't store the original image in the clipboard, but two
entries:
1. image/png with the frame of the copy moment
2. text/html with the markup of the gif img element
This commit adds an heuristic that detects this and makes us pick the
clipboard content of text/html instead of the image/png when this
happens.
From there our existing HTML paste logic handles and converts the HTML
img tag into markdown, preserving even the alt text.
See https://meta.discourse.org/t/-/218720 for context.
We rolled out a change to disable canonical indexing.
The goal behind it was to limit crawl budget by Google being spent
scanning non canonical topic links.
Since this change was applied we rolled out 2 fixes that made the change
no longer needed.
1. Topic RSS feeds are no longer followed, links in the RSS feeds are
not followed.
2. Post RSS feeds now contain canonical links.
Combined these two changes mean crawlers no longer discover a large
amount on non-canonical links on Discourse sites.
share-topic modal is used everywhere expect when clicking on the top
right corner of the post. This changes standardize on share-topic modal
and add the missing features from share-popup.
The `testem.scss` include triggers a live reload locally. We need these
styles when running `ember test --server`, so this loads that stylesheet
only in that scenario.
Missing plugin gems are installed when the app is being loaded.
That means when you run `bin/rails plugin:install_all_gems` it first installs missing gems and then reinstalls all gems…
Also, the method these rake tasks were using to install gems was very crude, and the regex there was incorrect which resulted in failures in certain cases. Though that didn't matter since those gems were being installed using a correct method just moments before…
* FEATURE: use canonical links in posts.rss feed
Previously we used non canonical links in posts.rss
These links get crawled frequently by crawlers when discovering new
content forcing crawlers to hop to non canonical pages just to end up
visiting canonical pages
This uses up expensive crawl time and adds load on Discourse sites
Old links were of the form:
`https://DOMAIN/t/SLUG/43/21`
New links are of the form
`https://DOMAIN/t/SLUG/43?page=2#post_21`
This also adds a post_id identified element to crawler view that was
missing.
Note, to avoid very expensive N+1 queries required to figure out the
page a post is on during rss generation, we cache that information.
There is a smart "cache breaker" which ensures worst case scenario is
a "page drift" - meaning we would publicize a post is on page 11 when
it is actually on page 10 due to post deletions. Cache holds for up to
12 hours.
Change only impacts public post RSS feeds (`/posts.rss`)
* DEV: Deprecate /posts/:id/reply-ids/all
It was added in ed4c0c4a63 and its only use was removed in b58867b6e9
Nothing in all-the* seems to be using this endpoint.
* Update app/controllers/posts_controller.rb

Eventually we want to remove JQuery, but that's a long way off. Installing this package will stop ember-cli printing the deprecation warning on every boot
```
DEPRECATION: The integration of jQuery into Ember has been deprecated and will be removed with Ember 4.0. You can either opt-out of using jQuery, or install the `@ember/jquery` addon to provide the jQuery integration. Please consult the deprecation guide for further details: https://emberjs.com/deprecations/v3.x#toc_jquery-apis

This update topic route has never worked. Better late than never. I am
in favor of using non-slug urls when using the api so I do think we
should fix this route.
Just thought I would update the `:id` param to `:topic_id` here in the
routes file instead of updating the controller to handle both params.
Added a spec to test this route.
Also added the same constraint we have on other topic routes to ensure
we only pass in an ID that is a digit.
The `blocked onebox domains` setting lets site owners change what sites
are allowed to be oneboxed. When a link is entered into a post,
Discourse checks the domain of the link against that setting and blocks
the onebox if the domain is blocked. But if there's a chain of
redirects, then only the final destination website is checked against
the site setting.
This commit amends that behavior so that every website in the redirect
chain is checked against the site setting, and if anything is blocked
the original link doesn't onebox at all in the post. The
`Discourse-No-Onebox` header is also checked in every response and the
onebox is blocked if the header is set to "1".
Additionally, Discourse will now include the `Discourse-No-Onebox`
header with every response if the site requires login to access content.
This is done to signal to a Discourse instance that it shouldn't attempt
to onebox other Discourse instances if they're login-only. Non-Discourse
websites can also use include that header if they don't wish to have
Discourse onebox their content.
Internal ticket: t59305.
