Under some conditions, these varied responses could lead to cache poisoning, hence the 'security' label.
Previously the Rails application would serve JSON data in place of HTML whenever Ember CLI requested an `application.html.erb`-rendered page. This commit removes that logic, and instead parses the HTML out of the standard response. This means that Rails doesn't need to customize its response for Ember CLI.
Part of overall strategy to remove jQuery file uploader
from the codebase. Also added some helper functionality to
the uppy mixin to allow for non-autostart uploads (all
previous upload changes have been for auto start components.)
The commit 20b2a42f49 broke
upload handlers, because previously we passed through the
native File object to the handler, not the uppy-wrapped
File object.
* REFACTOR: Improve support for consolidating notifications.
Before this commit, we didn't have a single way of consolidating notifications. For notifications like group summaries, we manually removed old ones before creating a new one. On the other hand, we used an after_create callback for likes and group membership requests, which caused unnecessary work, as we need to delete the record we created to replace it with a consolidated one.
We now have all the consolidation rules centralized in a single place: the consolidation planner class. Other parts of the app looking to create a consolidable notification can do so by calling Notification#consolidate_or_save!, instead of the default Notification#create! method.
Finally, we added two more rules: one for re-using existing group summaries and another for deleting duplicated dashboard problems PMs notifications when the user is tracking the moderator's inbox. Setting the threshold to one forces the planner to apply this rule every time.
I plan to add plugin support for adding custom rules in another PR to keep this one relatively small.
* DEV: Introduces a plugin API for consolidating notifications.
This commit removes the `Notification#filter_by_consolidation_data` scope since plugins could have to define their criteria. The Plan class now receives two blocks, one to query for an already consolidated notification, which we'll try to update, and another to query for existing ones to consolidate.
It also receives a consolidation window, which accepts an ActiveSupport::Duration object, and filter notifications created since that value.
Recently, the wrong new behavior appeared – we started to suggest to invited users usernames like "user1".
To reproduce:
1. Create an invitation with default settings, do not restrict it to email
2. Copy an invitation link and follow it in incognito mode
See username already filled, with eg “user1”. See screenshot. Should be empty.
This bug was very likely introduced by my recent changes to UserNameSuggester.
* Running the tests only in the ember cli env hid the fact that the pending posts feature wasn't working in the legacy environment
* Tests were using ember-cli-only APIs while there are widely used testing APIs in Discourse that support both ember envs
* `ember-test-selectors` was in both dependencies and devDependencies in discourse/package.json
* `qunit-dom` in package.json was not only unused but also defunct, as it wasn't pulled into the legacy env app
A followup to #14501, and #15128.
Some reports, like the Web Crawler User Agents report, have very long strings that need to be truncated when displayed. However, there is no way to see the full value without exporting the report or inspecting the elements using dev tools. This PR set a `title` attribute with the full value to the reports `<td>` elements so that the full value is shown on hover.
A post error validation would return a 422 status code. This status code was not accepted with the recent changes to bootstrap-json/index.js and would return a "Discourse Build Error" string, preventing any kind of bootbox popup error in the composer.
We have a couple of site setting, `slow_down_crawler_user_agents` and `slow_down_crawler_rate`, that are meant to allow site owners to signal to specific crawlers that they're crawling the site too aggressively and that they should slow down.
When a crawler is added to the `slow_down_crawler_user_agents` setting, Discourse currently adds a `Crawl-delay` directive for that crawler in `/robots.txt`. Unfortunately, many crawlers don't support the `Crawl-delay` directive in `/robots.txt` which leaves the site owners no options if a crawler is crawling the site too aggressively.
This PR replaces the `Crawl-delay` directive with proper rate limiting for crawlers added to the `slow_down_crawler_user_agents` list. On every request made by a non-logged in user, Discourse will check the User Agent string and if it contains one of the values of the `slow_down_crawler_user_agents` list, Discourse will only allow 1 request every N seconds for that User Agent (N is the value of the `slow_down_crawler_rate` setting) and the rest of requests made within the same interval will get a 429 response.
The `slow_down_crawler_user_agents` setting becomes quite dangerous with this PR since it could rate limit lots if not all of anonymous traffic if the setting is not used appropriately. So to protect against this scenario, we've added a couple of new validations to the setting when it's changed:
1) each value added to setting must 3 characters or longer
2) each value cannot be a substring of tokens found in popular browser User Agent. The current list of prohibited values is: apple, windows, linux, ubuntu, gecko, firefox, chrome, safari, applewebkit, webkit, mozilla, macintosh, khtml, intel, osx, os x, iphone, ipad and mac.
* DEV: Improve PresenceChannel state storage
Replaces some objects with Maps, and removes the redundant _presentChannels Set.
* DEV: Automatically leave PresenceChannels when in the background
If a tab has been in the background for 10s, or there has been no user activity for 60s, then the user will be removed from all PresenceChannels until activity resumes. Developers can opt-out of this by passing `{onlyWhileActive: false}` to the `enter` method.
The leak was introduced in #11722 and a test was added that relied on it in #14563
This PR fixes the leak (bookmarks-test), fixes the test that relied on it (fast-edit-test), and repleces some ad-hoc code with cloneJSON helper (other files)
The inProgressUploads is meant to be used to display these uploads
in a UI, and Ember will only update the array in the UI if pushObject
is used to notify it.
This is a big change to change over to using the uppy
upload mixin in the composer by default. This gets rid
of the temporary composer-editor-uppy component, as well
as removing the old ComposerUpload mixin and copying over
any missing functions that were not yet implemented by
ComposerUploadUppy. This has been working well on our
hosting for some time now and has led us to several
bug fixes.
This commit also deletes the old plugin API for adding
preprocessors for the uploads. The accepted method of doing
this now is via an uppy preprocessor plugin, which we have
several examples of in the core codebase.
Leaving the `enable_experimental_composer_uploader` site setting
intact for now because some plugins still rely on it, this
will be removed at a later date.
One step closer to ending the jQuery file uploader saga...
Widgets instances are ephemeral - they change on every re-render. We always want to notify the 'most recent' widget instance of events. This regressed in 1b9cf1b1 because the touchStart and drag hooks would persist the widget instance from the initial render. This commit switches TouchStart and Drag back to the pattern other events use, so that the most recent instance is always called. The performance benefits of per-element event listeners are retained.
Currently when a user creates posts that are moderated (for whatever
reason), a popup is displayed saying the post needs approval and the
total number of the user’s pending posts. But then this piece of
information is kind of lost and there is nowhere for the user to know
what are their pending posts or how many there are.
This patch solves this issue by adding a new “Pending” section to the
user’s activity page when there are some pending posts to display. When
there are none, then the “Pending” section isn’t displayed at all.
In jQuery file upload land, we were sending a single file through
at a time to matching upload handlers. This in turn required plugin
authors to marshal the files as they came through one by one if they
wanted to group them together to do something with them. Now that
we are using uppy, files come through in the groups they are added
in (for example dropping multiple, selecting multiple from the system
file dialogue).
This commit changes the matching upload handlers to send through
all matching files at once instead of piecemeal.
Error introduced in #14781
```
Error: Assertion Failed: You attempted to update <(unknown):ember3217>.bookmarks to "<(unknown):ember3846>", but it is being tracked by a tracking context, such as a template, computed property, or observer. In order to make sure the context updates properly, you must invalidate the property when updating it. You can mark the property as `@tracked`, or use `@ember/object#set` to do this.
```
In f6528afa01 I added parity support
for composer upload handlers to the uppy-ized composer. However the
way I assumed that it was only possible to handle a single file
upload at a time was false; it only appeared this way in the old
jQuery file upload composer because jQuery file upload sent through
files one at a time even if multiple were added at once. This caused
issues in certain plugins and themes by third parties.
This commit fixes the issue by making the uppy upload handler work
the same as the old one, by capturing all of the added files that
have matching handlers then going through them one by one and passing
them to the handler function.
For widget event handlers, we register a single listener on the `<body>`, and then notify the relavent widget (if any) when the event fires.
`touchstart` and `touchmove` events are particularly performance sensitive because they block scrolling on mobile. Therefore we want to avoid registering global non-passive listeners for these events.
This commit updates the WidgetTouchStartHook and WidgetDragHook implementations to automatically register listeners on the specific widget DOM elements when required.
This commit removes the last global scroll-blocking event handler from Discourse core. That means that mobile scrolling is now completely decoupled from our JS app. Even if the JS app is completely blocked (e.g. during rendering), scrolling will now continue to work. This should make things feel a lot smoother, especially on lower performance devices.
These were set to `passive: true` in ff72522f.
However, two consumers of this mixin (topic-navigation and site-header) do need to call `e.preventDefault()`, so we can't use passive listeners here.
That's ok, because this mixin only applies to a specific component's element, not the entire page. So having these non-passive listeners doesn't affect the vast majority of scrolling
This mixin calls the "scrolled" method of some object with no parameters, so there is no way that consumers would ever call `event.preventDefault()`. Therefore we can make the listeners passive, and improve scrolling performance on mobile.
This commit also updates the mixin to remove JQuery usage. The API is slightly modified to remove the need for an event 'name' for binding/unbinding.
The calls to `.bindScrolling` and `.unbindScrolling` in user-stream.js are removed because they are already called by the LoadMore mixin which is applied to the component.
The `bindScrolling` method claimed to offer debouncing-by-default. However, a bug in the `opts` parsing meant that debouncing was skipped if a 'name' was passed in. Therefore the only consumer actually being debounced was the LoadMore mixin. This commit fixes the opts parsing, so all consumers get the same behavior.
However, when scrolling, debounce is rarely what we want. The documentation of `bindScrolling` says "called every 100ms". In fact, debounce means that the functions were only called 'after the user **stops scrolling** for 100ms'. If you're scrolling very slowly (e.g. when using momentum-based scrolling on mobile), then this can be quite frustrating. This is why "Load more" is only triggered on topics/topic-lists when you completely stop scrolling.
Therefore, this commit also replaces the default 'debounce' with a 'throttle'. The 'throttle' is configured with `immediate = false`, so that it fires on the trailing edge, and therefore the final call will always be **after** we finish scrolling. (the default `immediate: true` would fire on the leading edge, and so the last call could be up to 100ms **before** we finish scrolling).
Registering non-passive listeners for the touchstart event can affect scroll performance on mobile devices, and now shows a warning in Chrome. Our current version of Ember unconditionally registers all event listeners, even if they're unused. It also doesn't support passive event listeners. Once we get to Ember 4.0, it lazily registers event listeners, and supports passive listeners via the `{{on` helper.
We already disable the ember `mousemove` and `touchmove` events for performance, so it makes sense to do the same for `touchstart`. We are not using `touchstart` anywhere in core, and I cannot find any official/unofficial plugins which use it. If a `touchstart` event is required, plugins/themes can always register their own listeners (preferably on a specific element, rather than the whole `document`)
We do call `event.preventDefault()` on these events. They're limited to a single element, so performance impact should be negligable. Adding `passive: false` prevents the chrome dev tools warning.
None of these places call `event.preventDefault()`. Therefore we can register the event listeners as 'passive', and improve scroll performance on mobile devices.
Skipping methods we don't use gives us mem/perf gains (minuscule but still), but more importantly fixes warnings about `Poll#open` (created by `enum :status`) conflicting with some internal AR method. 😃
Calling `setProperty("--header-offset", newValue)` will always cause a 'Recalculate Style' event, even if the value is unchanged. On my browser, these 'Recalculate Style' events take about 6-7ms each time the `dockCheck` function is run.
This commit stores the 'previous' value in an instance variable, and only calls setProperty if the value has changed. This brings the total runtime of `dockCheck` down to about 70µs on my machine.
`pending`, `approved`, `rejected`, `ignored`, and `deleted` scope method were accessible on all model classes… 😂
Fixes `Creating scope :pending. Overwriting existing method DiscoursePostEvent::EventDate.pending.` warnings.
