Previously we only allowed one image optimization per machine, this meant there
was cross talk between avatar resizing and Sidekiq. This could lead to large
amounts of starvation when optimized image version changed which in turn could
block the Sidekiq queue.
This increases amount of allowed load on machines but this is preferable to
having crosstalk between avatar resizing and Sidekiq.
Some cloud providers (Google Memorystore) do not support any CLIENT commands
By setting :id to nil in the redis config hash we can avoid these commands.
This adds a special global setting GCE users can enable:
`DISCOURSE_REDIS_SKIP_CLIENT_COMMANDS = true`
This is a possible solution for https://meta.discourse.org/t/user-api-keys-specification/48536/19
This allows for user-api-key requests to not require a redirect url.
Instead, the encypted payload will just be displayed after creation ( which can be copied
pasted into an env for a CLI, for example )
Also: Show instructions when creating user-api-key w/out redirect
This adds a view to show instructions when requesting a user-api-key
without a redirect. It adds a erb template and json format.
Also adds a i18n user_api_key.instructions for server.en.yml
Previously non lightboxed images would render in the wrong spot while loading.
We assumed the image we were rendering while loading was at 0,0 position.
This is not the case on non-lightboxed images cause they have no surrounding
DIV.
We have the periodical job that regularly will rebake old posts. This is
used to trickle in update to cooked markdown. The problem is that each rebake
can issue multiple background jobs (post process and pull hotlinked images)
Previously we had no per-cluster limit so cluster running 100s of sites could
flood the sidekiq queue with rebake related jobs.
New system introduces a hard limit of 300 rebakes per 15 minutes across a
cluster to ensure the sidekiq job is not dominated by this.
We also reduced `rebake_old_posts_count` to 80, which is a safer default.
This reverts commit 993f847a2c.
There is an edge case where the link click redirect fails when the URL has trailing slash. Need to figure out a better fix for this.
Previously we had no idea what algorithm generated thumbnails, this starts tracking the version.
We also bumped up the version to force all optimized images to be generated. This is important cause we recently introduced pngquant which results in much smaller images.
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.
To ensure safety we only apply this optimisation to images smaller than 500k.
This commit also makes a bunch of image specs less fragile.
This margin is not needed and doesn't exist in the mobile view.
It causes a bit of a problem in desktop topics with no categories and more prominently in PMs in the desktop view.
There's a small TODO here where the rest of the extra-info-wrapper styles should all be moved to header sylesheets.
Previously if upload had missing width and height we would calculate
on first use BUT we (me) forgot to save this to the database
This was particularly bad on home page cause category images (when old)
miss dimensions.
This allows fidelity in controlling excerpt (text that shows up when you pin a topic or link to it externally):
```
I am some text
[excerpt]
This is some **custom** markdown that should be the excerpt
[/excerpt]
More text
```
Previous solution relied on DIVs, unfortunately DIVs do not play well,
by design with mixing markdown unless you have a preceding newline eg:
```
<div class='hello'>
this will be treated properly as markdown
</div>
```
This extra newline is not desirable.
I am also considering adding
```
[div class=excerpt]
[/div]
```
This would offer lots of flexibility to themes and plugins that do not want the extra annoying newline.
- Now applied to all images over 150x150px
- Stores the width and height in the WeakMap rather than using
percentages for accuracy
- When oneboxed images are hidden, they are given a subtle border for better
visibility.
- Don't apply when in the composer. Causes flickering.
With our recent move to SVG icons, the font file does not work in the wizard. I've opted for path2D, which accepts an SVG path
Path2D is not supported by IE11 but the chances of admins running the wizard on IE11 are practically none.

* Add category link renderer to plugin API
- lets themes/plugins override the category link display
- planning to use this in a "category icons" theme component
* small code review fix
* Code review refactor
This generates a 10x10 PNG thumbnail for each lightboxed image.
If Image Lazy Loading is enabled (IntersectionObserver API) then
we'll load the low res version when offscreen. As the image scrolls
in we'll swap it for the high res version.
We use a WeakMap to track the old image attributes. It's much less
memory than storing them as `data-*` attributes and swapping them
back and forth all the time.
* Dashboard doesn't timeout anymore when Amazon S3 is used for backups
* Storage stats are now a proper report with the same caching rules
* Changing the backup_location, s3_backup_bucket or creating and deleting backups removes the report from the cache
* It shows the number of backups and the backup location
* It shows the used space for the correct backup location instead of always showing used space on local storage
* It shows the date of the last backup as relative date
`SiteSerializer#is_readonly` is cached for an anonymous user so we have
to clear the cache when disabling readonly mode. Otherwise, the site may
appear to be in readonly mode for an extended period of time.
This would prevent failure with connectors templates defining actions as closures. In this case action existence is checked at compile time and not runtime.
When a quote is not expanded and it contains lightboxes, those lightboxes are not displayed and instead we show a link that looks like this `[image_title]`
These still have the lightbox CSS class and so they still get the backgrounds we add to lightboxes while they load. Increasing the selector specificity prevents that from happening.
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.
This feature is used for defer loading of images and in future for post cloaking
This gives us a polyfill so we can safely use the feature in problem browsers
The polyfill supports "polling" but it does not appear we need it yet.
If we discover anything odd here, consider setting poll interval per:
https://github.com/w3c/IntersectionObserver/tree/master/polyfill
```
var io = new IntersectionObserver(callback);
io.POLL_INTERVAL = 100; // Time in milliseconds.
```
Keeping the mutation observer cause we often mutate the DOM
Previously the 'reconnect' process was a bit magic - IF you were already logged into discourse, and followed the auth flow, your account would be reconnected and you would be 'logged in again'.
Now, we explicitly check for a reconnect=true parameter when the flow is started, store it in the session, and then only follow the reconnect logic if that variable is present. Setting this parameter also skips the 'logged in again' step, which means reconnect now works with 2fa enabled.
Some URLs in browsers are non compliant and contain twos `#` this commit adds
special handling for this edge case by auto encoding any fragments containing `#`
Do not send an activation email to users invited via email. They
already confirmed their email address by clicking the invite link.
Users invited via link will need to confirm their email address before
they can login.
This adds a **very basic** support for share to Discourse.
Currently, this is only supported in Android + Chrome 71+.
After installing a Discourse site to the Home Screen, you will be
able to share from anywhere in the OS to the Discourse site.
Discourse will use the title and text from the share event.
- Fixes a performance issue on a site with lots of images in posts
- turns out that "filter: invert(100%)" performs very poorly on Safari/iPhone
- also disables transition on the element on mobile
The wizard searches for:
* a topic that with the "is_welcome_topic" custom field
* a topic with the correct slug for the current default locale
* a topic with the correct slug for the English locale
* the oldest globally pinned topic
It gives up if it didn't find any of the above.
* Starting to remove category column from topic list
* stacked nav alignment adjustment
* Revert "stacked nav alignment adjustment"
This reverts commit 98800c7058.
* remove comment
* removing function
This was an indentation mistake introduced in 44eba0b. Pretty understandable, considering we are indented 8 levels deep in this method. Will follow-up with a refactor to improve this.
Previously the push notification code path was not tested for notification
collapsing. This happens if you get multiple replies to a topic you are
watching.
