Why this change?
By default in the test environment, MessageBus used the memory backend
which means all messages are stored in an in-memory data structure. However,
the in-memory data structure is not cleared after each system test so we
have the potential to be leaking stuff between system tests.
Similarly for the defer queue which process work in another thread, we
want to ensure that the defer queue processes everything it has to do
before the transaction is rolled back.
If a selenium finder takes the full wait duration to resolve, that means it has been written inefficiently. Most likely a matcher has been negated incorrectly.
This commit introduces a patch which will raise an error in this situation so that we can catch the issues while developing specs.
This commit also fixes chat's visit_thread helper. It was spinning on `has_css?(".chat-skeleton")` for the full selenium wait duration, and then returns false. That's because the thread is often already fully loaded before `has_css?` is even called. It's now updated to only look for the final expected state.
What is the problem here?
In multiple controllers, we are accepting a `limit` params but do not
impose any upper bound on the values being accepted. Without an upper
bound, we may be allowing arbituary users from generating DB queries
which may end up exhausing the resources on the server.
What is the fix here?
A new `fetch_limit_from_params` helper method is introduced in
`ApplicationController` that can be used by controller actions to safely
get the limit from the params as a default limit and maximum limit has
to be set. When an invalid limit params is encountered, the server will
respond with the 400 response code.
* CHROME_LOAD_EXTENSIONS_MANIFEST - An env var with a path to a file
that contains one path per line. These are paths to extensions installed
in chrome that the user wants to load while running system specs.
Useful to run things like Ember Inspector.
* CHROME_DISABLE_FORCE_DEVICE_SCALE_FACTOR - On some systems the
--force-device-scale-factor=1 argument makes the UI for chrome
super small, add a way to disable this.
This commit makes sure we don't load all data into memory when doing CSV exports.
The most important change here made to the recently introduced export of chat
messages (3ea31f4). We were loading all data into memory in the first version, with
this commit it's not the case anymore.
Speaking of old exports. Some of them already use find_each, and it worked as
expected, without loading all data into memory. And it will proceed working as
expected after this commit.
In general, I made sure this change didn't break other CSV exports, first manually, and
then by writing system specs for them. Sadly, I haven't managed yet to make those
specs stable, they work fine locally, but flaky in GitHub actions, so I've disabled them
for now.
I'll be making more changes to the CSV exports code soon, those system specs will be
very helpful. I'll be running them locally, and I hope I'll manage to make them stable
while doing that work.
Instead of having to remember every time, just always wait until the
current transaction (if it exists) has committed before clearing any
DistributedCache.
The only exception to this is caches that aren't caching things from
postgres.
This means we have to do the test setup after setting the test
transaction, because doing the test setup involves clearing caches.
Reapplying this - it now doesn't use after_commit if skip_db is set

Introduced in cec68b3e2c,
this is flaky because if you click the back button before
the route is fully transitioned to the loaded thread,
we end up going to the history _before_ the thread list,
which ends up being the channel.
We need to make sure that everything is loaded for the
thread first, meaning the skeleton is not there.
Also exclude some noise from the capybara logs (image load failures)
Clicking on TOC heading anchors in a subfolder setup was breaking the current URL for users.
Other than the fix this change introduces the ability to test the subfolder setup in system specs.
It seems like the overhead of GPU acceleration is not worth it and is
slowing down our system tests. Locally the following command completes
in `2 minutes 8.6 seconds` with GPU disabled as compared to `2 minutes 45.4 seconds` with GPU enabled.
## What is the problem?
MessageBus by default uses long polling which keeps a connection
open for 25 seconds by default. The problem here is that Capybara does not know about these
connections being kept opened by MessageBus and hence does not know how
to stop these connections at the end of each test. As a result, the long polling MessageBus connections are kept opened by the browser and we hit chrome's limit of 6 concurrent requests per host, new request made in the browser is marked as "pending" until a request is freed up. Since we keep a MessageBus long polling connection opened for 25 seconds, our finders in Capybara end up hitting Capybara's wait time out causing the tests to fail.
## What is the fix?
Since we can't rely on Capybara to close all the existing Capybara
connections, we manually execute a script to stop all MessageBus
connections after each system test.
```
for i in {1..10}; do
echo "Running iteration $i"
PARALLEL_TEST_PROCESSORS=8 CAPYBARA_DEFAULT_MAX_WAIT_TIME=10 bin/turbo_rspec --seed=34908 --profile --verbose --format documentation spec/system
if [ $? -ne 0 ]; then
echo "Error encountered on iteration $i"
exit 1
fi
done
echo "All 10 iterations completed successfully"
```
Without the fix, the script fails consistently in the first few iterations. Running in non-headless mode with the "network" tab opened will reveal the requests that are marked as pending.
Rescuing them still makes timing-out tests fail but doesn't break `after` spec cleanup (which could trigger more errors) Using custom error class to avoid any other possible timeout-catching code.
Also:
* remove an unnecessary `.select { |x| x.size > 0 }`
* fix a typo in a test title
Why is this change required?
By default, `RSpec` comes with a `--profile=[COUNT]` option as well but
enabling that option means that the entire test suite needs to be
executed. This does not work so well for `turbo_rspec` which splits our
test files into various "buckets" for the tests to be executed in
multiple processes. Therefore, this commit adds a similar
`--profile=[COUNT]` option to `turbo_rspec` but will only profile the
tests being executed. Examples:
`LOAD_PLUGINS=1 bin/turbo_rspec --profile plugins/*/spec/system`
or
`LOAD_PLUGINS=1 bin/turbo_rspec --profile=20 plugins/*/spec/system`
What is this change?
This change is an attempt to avoid flakiness in our tests due to
animations being enabled in our tests. An example of flakiness caused by
animations is when the `find(selector).click` pattern is used. When
`find(selector)` returns the node, its position may have changed if the
element is still moving. However, the `click` method will end up
clicking on the old position.
Either way, there is no need for us to make system tests even more
complicated by enabling animations.
Usage:
```
CHROME_DEV_TOOLS=bottom bundle exec rspec /path/to/system/spec
```
This commit also regroups common chrome options under `apply_base_chrome_options`, and removes the size of the mobile window which was incorrect. browser_log param is also passed to mobile chrome options.
New headless shares the same implementation as the chrome browser
instead of being a separate implementation of its own.

This commit also includes two changes to the rails helper which make tests more consistent on different devices. With this change the failure was reproducible locally and not only on CI:
```
options.add_argument("--force-device-scale-factor=1")
```
The fix itself is quite simple and attempts to find safe click coordinates, the previous solution could fail depending on the size of the sidebar.
* Color for turbo_rspec in CI (`progress` and `documentation` formats)
* Show "DONE" only when `documentation` formatter is used
* Fix formatting
* Collapse RSpec commands
* Add line wrapping to the `progress` formatter (to mitigate GH Actions issue)
This pull request is a full overhaul of the chat-composer and contains various improvements to the thread panel. They have been grouped in the same PR as lots of improvements/fixes to the thread panel needed an improved composer. This is meant as a first step.
### New features included in this PR
- A resizable side panel
- A clear dropzone area for uploads
- A simplified design for image uploads, this is only a first step towards more redesign of this area in the future
### Notable fixes in this PR
- Correct placeholder in thread panel
- Allows to edit the last message of a thread with arrow up
- Correctly focus composer when replying to a message
- The reply indicator is added instantly in the channel when starting a thread
- Prevents a large variety of bug where the composer could bug and prevent sending message or would clear your input while it has content
### Technical notes
To achieve this PR, three important changes have been made:
- `<ChatComposer>` has been fully rewritten and is now a glimmer component
- The chat composer now takes a `ChatMessage` as input which can directly be used in other operations, it simplifies a lot of logic as we are always working a with a `ChatMessage`
- `TextareaInteractor` has been created to wrap the existing `TextareaTextManipulation` mixin, it will make future migrations easier and allow us to have a less polluted `<ChatComposer>`
Note ".chat-live-pane" has been renamed ".chat-channel"
Design for upload dropzone is from @chapoi
Similar spirit to e195e6f614,
this moves the Bookmarkable registration to DiscoursePluginRegistry
so plugins which are not enabled do not register additional
bookmarkable classes.
This commit introduces the skeleton of the chat thread UI. The
structure of the components looks like this. Its done this way
so the side panel can be used for other things as well if we wish,
not just for threads:
```
.main-chat-outlet
<ChatLivePane />
<ChatSidePanel>
<-- rendered with {{outlet}} -->
<ChatThread />
</ChatSidePanel>
```
Later on the `ChatThreadList` will be rendered here as well.
Now, when you go to a channel you can open a thread by clicking
on either the Open Thread message action button or by clicking on
the reply indicator. This will take you to a route like `chat/c/:slug/:channelId/t/:threadId`.
This works on mobile as well.
This commit includes basic serializers and routes for threads,
as well as a new `ChatThreadsManager` service in JS that caches
threads for a channel the same way the channel threads manager does.
The chat messages inside the thread are intentionally left out
until a later PR.
**NOTE: These changes are gated behind the site setting enable_experimental_chat_threaded_discussions
and the threading_enabled boolean on a ChatChannel**
* DEV: Rnemae channel path to just c
Also swap the channel id and channel slug params to be consistent with core.
* linting
* channel_path
* Drop slugify helper and channel route without slug
* Request slug and route models through the channel model if possible
* DEV: Pass messageId as a dynamic segment instead of a query param
* Ensure change is backwards-compatible
* drop query param from oneboxes
* Correctly extract channelId from routes
* Better route organization using siblings for regular and near-message
* Ensures sessions are unique even when using parallelism
* prevents didReceiveAttrs to clear input mid test
* we disable animations in capybara so sometimes the message was barely showing
* adds wait
* ensures finished loading
* is it causing more harm than good?
* this check is slowing things for no reason
* actually target the button
* more resilient select chat message
* apply similar fix to bookmark
* fix

In dev/prod, these are absorbed by unicorn. Most commonly, they occur when a client interrupts a message-bus long-polling request.
Also reverts the EPIPE workaround introduced in 011c9b9973
Having this set to ALL pollutes the JS system spec
logs with a bunch of unnecessary noise like this:
> "PresenceChannel '/chat-user/core/1' dropped message (received 315, expecting 246), resyncing..."
Or:
> "DEPRECATION: The \u003Cdiscourse@component:plugin-connector::ember1112>#save computed property was just overridden. This removes the computed property and replaces it with a plain value, and has been deprecated.
Now, we will only log errors. To configure this set
the `SELENIUM_BROWSER_LOG_LEVEL` env var.
Our working theory is that system tests on Github run on much less
powerful hardware as compared to running the tests on our work machines.
Hopefully, increasing the wait time now will help reduce some flakes
that we're seeing on Github.
It should fix flakeys we have due to using_session. This commit is also fixing tests which were failing constantly with treadsafe enabled.
A test has also bene skipped as the issue couldn't be found so far.

Previously, browser logs would be printed to STDOUT halfway through the test run. This commit changes the behaviour so that the logs are included in the failure summary along with other rspec failure information.
Currently the `turbo:spec` task will fail when encountering system
tests as Capypara tries to use the same port for each process.
This simple change uses the same strategy as for databases, by just
incrementing the port number by `TEST_ENV_NUMBER` for each process.
We are all in on system specs, so this commit moves all the chat quoting acceptance tests (some of which have been skipped for a while) into system specs.
Follow up to a review in #18937, this commit changes the HashtagAutocompleteService to no longer use class variables to register hashtag data sources or types in context priority order. This is to address multisite concerns, where one site could e.g. have chat disabled and another might not. The filtered plugin registers I added will not be included if the plugin is disabled.
This ensures that all system tests are starting from a clean state and
not leak state between requests. Note that we have to simplify flush the
Redis db here because it is not pratical to manually clean up Redis keys
in system tests.
