* FIX: Rejected emails should not be cleaned up before their logs
If we delete the rejected emails before we delete their associated logs
we will receive 404 errors trying to inspect an email message for that
log.
* don't add a blank line
* test for max value as well
* pr cleanup and add migration
* Fix failing test
The site.json endpoint was missing some optional fields on the
categories property that is returned. This commit documents the
`parent_category_id` which is present if there are subcategories and it
also documents the `custom_fields` property which the chat plugin is
using causing some flaky tests.
* DEV: Fix flaky admin badges.json api docs spec
This commit is to fix this incredibly vague error message:
```
Failure/Error: expect(valid).to eq(true)
expected: true
got: false
```
From this test:
> Assertion: badges /admin/badges.json get success response behaves like
> a JSON endpoint response body matches the documented response schema
I was finally able to repro locally using parallel tests:
```
RAILS_ENV=test bundle exec ./bin/turbo_rspec
```
I *think* the parallel tests might be swallowing the `puts` output, but
when I also specified the individual spec file
```
RAILS_ENV=test bundle exec ./bin/turbo_rspec spec/requests/api/badges_spec.rb
```
It revealed the issue:
```
VALIDATION DETAILS: {"missing_keys"=>["i18n_name"]}
```
``` ruby
...
def include_i18n_name?
object.system?
end
```
Looks like if the "system" user isn't being used the `i18n_name` won't
be returned in the json response so we shouldn't mark it as a required
attribute.
* Switch to using fab!
When using `let(:badge)` to fabricate a test badge it wouldn't be
returned from the controller, but switching to using `fab!` allows it to
be returned in the json data giving us a non-system badge to test
against.
The category description fields as part of the rswag specs for the
site.json endpoint were flakey. Removing the `required` attribute allows
us to still document that these fields exists, but that depending on
certain site settings they may not be present in the response.
This reverts one of the changes introduced just now in:
27d7b0c6de
I don't think we need this `activated_not_suspended_not_staged` scope
because we can just compose it ourselves via method chaining like
`User.activated.not_suspended.not_staged`.
* FIX: Email Send post has already been taken error
Adding a failing test first before coming up with a good solution.
Related: 357011eb3b
The above commit changed
```
PostReplyKey.find_or_create_by_safe!
```
to
```
PostReplyKey.create_or_find_by!
```
But I don't think it is working as a 1-1 replacement because of the
`Validation failed: Post has already been taken` error we are receiving
with this change. Also we need to make sure we don't re-introduce any
concurrency issues.
Reported: https://meta.discourse.org/t/224706/13
* Remove rails unique constraint and rely on db index
I believe this is what is causing `create_or_find_by!` to fail. Because
we have a unique constraint in the db I think we can remove this rails
unique constraint?
* clean up spec wording
Via the API it is possible to create a user with an integer username. So
123 instead of "123". This causes the following 500 error:
```
NoMethodError (undefined method `unicode_normalize' for 1:Integer)
app/models/user.rb:276:in `normalize_username'
```
See: https://meta.discourse.org/t/222281
* DEV: Allow params to be passed on topic redirects
There are several places where we redirect a url to a standard topic url
like `/t/:slug/:topic_id` but we weren't always passing query parameters
to the new url.
This change allows a few more query params to be included on the
redirect. The new params that are permitted are page, print, and
filter_top_level_replies. Any new params will need to be specified.
This also prevents the odd trailing empty page param that would
sometimes appear on a redirect. `/t/:slug/:id.json?page=`
* rubocop: fix missing space after comma
* fix another page= reference
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.
This change adds support for the categories endpoint to have an api
scope. Only adds GET scope for listing categories and for fetching a
single category.
See: https://meta.discourse.org/t/218080/4
* DEV: Show only top level replies
Adds a new query param to the topic view so that we can filter out posts
that aren't top level replies. If a post is a reply to another post
instead of the original topic post we should not include it in the
response if the `filter_top_level_replies` query param is present.
* add rspec test
* DEV: Document external topic id endpoints
This commit documents the existing Create Topic endpoint with the
`external_id` param and documents the new get topic by external id
endpoint.
It also refactors the existing topic show endpoint to use the new format
where we load the expected json schema response from a file.
See: 71f7f7ed49
* clean up unused test variables
* FEATURE: Add external_id to topics
This commit allows for topics to be created and fetched by an
external_id. These changes are API only for now as there aren't any
front changes.
* add annotations
* add external_id to this spec
* Several PR feedback changes
- Add guardian to find topic
- 403 is returned for not found as well now
- add `include_external_id?`
- external_id is now case insensitive
- added test for posts_controller
- added test for topic creator
- created constant for max length
- check that it redirects to the correct path
- restrain external id in routes file
* remove puts
* fix tests
* only check for external_id in webhook if exists
* Update index to exclude external_id if null
* annotate
* Update app/controllers/topics_controller.rb
We need to check whether the topic is present first before passing it to the guardian.

Probably best to lookup the "everyone" group_id instead of hard-coding
it to `0`. Also now its more clear what this `0` means.
* FIX: Tag watching for everyone tag groups
Tags in tag groups that have permissions set to everyone were not able
to be saved correctly. A user on their preferences page would mark the
tags that they wanted to save, but the watched_tags in the response
would be empty. This did not apply to admins, just regular users. Even
though the watched tags were being saved in the db, the user serializer
response was filtering them out. When a user refreshed their preferences
pages it would show zero watched tags.
This appears to be a regression introduced by:
0f598ca51e
The issue that needed to be fixed is that we don't track the "everyone"
group (which has an id of 0) in the group_users table. This is because
everyone has access to it, so why fill a row for every single user, that
would be a lot. The fix was to update the query to include tag groups
that had permissions set to the "everyone" group (group_id 0).
I also added another check to the existing spec for updating
watched tags for tags that aren't in a tag group so that it checks the
response body. I then added a new spec which updates watched tags for
tags in a tag group which has permissions set to everyone.
* Resolve failing tests
Improve SQL query syntax for including the "everyone" group with the id
of 0.
This commit also fixes a few failing tests that were introduced. It
turns out that the Fabrication of the Tag Group Permissions was faulty.
What happens when creating the tag groups without any permissions is
that it sets the permission to "everyone". If we then follow up with
fabricating a tag group permission on the tag group instead of having a
single permission it will have 2 (everyone + the group specified)! We
don't want this. To fix it I removed the fabrication of tag group
permissions and just set the permissions directly when creating the tag
group.
* Use response.parsed_body instead of JSON.parse
Adding a spec for documenting the delete post API endpoint for our api
docs. As part of this added detailed info for the `force_destroy`
parameter for permanently deleting a post.
The previous default aspect ratio for cropping tall images was a little
too strict and was cutting off images. This new setting should allow for
a larger range of image sizes before cropping them.
This is a fix to address blurry onebox favicon images if the site you
are linking to happens to have a favicon.ico file that contains multiple
images.
This fix detects of we are trying to create an upload for a favicon.ico
file. We then convert it to a png and not a jpeg like we were doing. We
want a png because it will preserve transparency, otherwise if we
convert it to a jpeg we lose that and it looks bad on dark themed sites.
This fix also addresses the fact that .ico files can include multiple
images. The blurry images we were producing was caused by the
ImageMagick `-flatten` option when the .ico file had multiple images
which then squishes them all together. So for .ico files we are no
longer flattening them and instead we are grabbing the last image in the
.ico bundle and converting that single image to a png.
Documenting the `/u/:username:/emails.json` endpoint.
Also removing some email fields from user api responses because they
aren't actually included in the response unless you are querying
yourself.
Change the type for default_calendar to a string.
The type specified for the default calendar in the api docs wasn't a
valid type. The linting in the api docs repo reports:
```
`type` can be one of the following only: "object", "array", "string", "number", "integer", "boolean", "null".
```
This linting currently is only in the `discourse_api_docs` repo.
* DEV: Add include_subcategories param to api docs
Adding the `include_subcategories=true` query param to the
`/categories.json` api docs.
Follow up to: fe676f334a
* fix spec
* FEATURE: Return subcategories on categories endpoint
When using the API subcategories will now be returned nested inside of
each category response under the `subcategory_list` param. We already
return all the subcategory ids under the `subcategory_ids` param, but
you then would have to make multiple separate API calls to fetch each of
those subcategories. This way you can get **ALL** of the categories
along with their subcategories in a single API response.
The UI will not be affected by this change because you need to pass in
the `include_subcategories=true` param in order for subcategories to be
returned.
In a follow up PR I'll add the API scoping for fetching categories so
that a readonly API key can be used for the `/categories.json` endpoint. This
endpoint should be used instead of the `/site.json` endpoint for
fetching a sites categories and subcategories.
* Update PR based on feedback
- Have spec check for specific subcategory
- Move comparison check out of loop
- Only populate subcategory list if option present
- Remove empty array initialization
- Update api spec to allow null response
* More PR updates based on feedback
- Use a category serializer for the subcategory_list
- Don't include the subcategory_list param if empty
- For the spec check for the subcategory by id
- Fix spec to account for param not present when empty
Due to the way that rswag expands shared components we were getting this
warning when linting our api docs:
```
Component: "user_response" is never used.
```
This change refactors the `api/users_spec.rb` file so that it uses the
new way of doing things with a separate `user_get_response.json` schema
file rather then the old way of loading a shared response inside of the
swagger_helper.rb file.
The color_scheme_id needs to be an integer not a string.
This is one of the failing tests that showed this error:
https://github.com/discourse/discourse/runs/3598414971
It showed this error
`POSSIBLE ISSUE W/: /user_themes/0/color_scheme_id`
And this is part of the site.json response:
```
...
"user_themes"=>[{"theme_id"=>149, "name"=>"Cool theme 111", "default"=>false, "color_scheme_id"=>37}]
...
```
One of the fields that should be present for openapi docs is the "license"
field.
https://spec.openapis.org/oas/latest.html#infoObject
Our API docs already had a license, so this commit just specifies that
and provides a link to it.
From the openapi spec:
https://spec.openapis.org/oas/latest.html#fixed-fields-7
each endpoint needs to have an `operationId`:
> Unique string used to identify the operation. The id MUST be unique
> among all operations described in the API. The operationId value is
> case-sensitive. Tools and libraries MAY use the operationId to uniquely
> identify an operation, therefore, it is RECOMMENDED to follow common
> programming naming conventions.
Running the linter on our openapi.json file with this command:
`npx @redocly/openapi-cli lint openapi.json`
produced the following warning on all of our endpoints:
> Operation object should contain `operationId` field
This commit resolves these warnings by adding an operationId field to
each endpoint.
* DEV: Use named parameters for dir-span helper
Follow up to: e50a5c0c73
In order to improve code clarity this change introduces named parameters
for the dir-span helper. This is specifically for the new `htmlSafe`
parameter which you can use instead of just passing in a boolean if the
strings you are passing in have already been escaped.
Before: `{{dir-span category.description false}}`
After: `{{dir-span category.description htmlSafe=true}}`
* Set default value for params arg
`nullable` is no longer a valid type, and types also can't be an empty
string, so just bringing a number of issues with types in compliance
with the openapi spec.
The latest openapi spec version is v3.1.0
https://spec.openapis.org/oas/v3.1.0
Specifying the latest version will allow our openapi spec linter to use
this version and allow use to use the new type format that allows for
specifying a type as "null", which we need because sometimes our api
responses include null values instead of a "string", "integer", or
"object" type.
See: https://stackoverflow.com/a/48114322/588458
* DEV: Return 400 instead of 500 for invalid top period
This change will prevent a fatal 500 error when passing in an invalid
period param value to the `/top` route.
* Check if the method exists first
I couldn't get `ListController.respond_to?` to work, but was still able
to check if the method exists with
`ListController.action_methods.include?`. This way we can avoid relying
on the `NoMethodError` exception which may be raised during the course
of executing the method.
* Just check if the period param value is valid
* Use the new TopTopic.validate_period method
This TODO comment has existed for 8 years. Sort must be working just
fine or we would have prioritized fixing it.
Removing this comment as a tiny step toward keeping our codebase nice
and tidy.
The main image_optim gem now includes the timeout feature
that we had in our fork. So it is now safe to switch off of our fork and
back to the image_optim gem.
This is the link to the commit in the image_optim repo that adds the
timeout option:
https://github.com/toy/image_optim/commit/ec3767dde0d9f9f3d18bd688645583d847ba2e13
One difference with the new timeout implementation is that image_optim
now handles the timeout exceptions instead of bubbling them up:
https://github.com/toy/image_optim/blob/1ed03285873078185c129c66007231469461e429/lib/image_optim.rb#L128-L129
```
rescue Errors::TimeoutExceeded
handler.result
```
So a timeout will just return `nil`, which is the same response if it
couldn't optimize an image. I don't think we were really watching for
or doing anything about these timeout warnings in our logs so I think
this is an okay change to have and we will have less warnings in our
logs now too.
It's been awhile since we have supported IE11 so it should be safe to remove
IntersectionObserver now.
From a TODO task in this repo:

* FIX: Be able to handle long file extensions
Some applications have really long file extensions, but if we truncate
them weird behavior ensues.
This commit changes the file extension size from 10 characters to 255
characters instead.
See:
https://meta.discourse.org/t/182824
* Keep truncation at 10, but allow uppercase and dashes
When creating a PM target_usernames has been deprecated for some time
now but the api docs have yet to reflect this.
The api docs now specify to use target_recipients.
See: eef21625c6
Some git repos have a different ssh url scheme than github and we should
support them.
This change updates our regex format to account for repos that don't
start with "git", but are still valid ssh urls.
Also I added some tests to account for the various formats and to ensure
we don't show the public key when using https urls.
See: https://meta.discourse.org/t/182668
The urls that we generate for mobile post notifications don't take into
account the subfolder url if a site happens to have one configured. When
this happens when you tap on a new mobile notification it takes you to
a url that doesn't work because it is missing the subfolder portion.
I honestly think this should be handled in the Post model like we do
with the Topic model. `Post.url` should know how to handle subfolder
installs, but that seemed like a very risky change because there are
lots of other places in the codebase where we tack on the base_path and
I didn't want to risk duplicating it.
I also found a small typo in the topics controller spec.
Unactivated users that have posts cannot be deleted so we shouldn't
include them in the initial query to try and purge them. Otherwise we
are just loading up sidekiq with pointless work to be doing every day.
Without this change if there are 201 unactivated users to purge, but the
first 200 have posts, the 201st user will never be deleted even though
it is the only user that doesn't have a post and is actually the one
that should be deleted.
This is an importer I wrote to restore some users that were
accidentally deleted for being purged as old staged users or old
unactivated users.
It reads from CSV files exported from a discourse sql backup.
When running an import script there are many site settings that are
changed but we reset them back to where they were originally before the
import. However, there are two settings that we don't roll back:
```
purge_unactivated_users_grace_period_days
purge_deleted_uploads_grace_period_days
```
which could have some unintended consequences.
My first question is do we *really* have to change these settings? I'm
not a huge fan of changing someones settings without them really knowing
they were changed.
If we really do have to change these settings here is my proposed PR
where we don't alter the `purge_unactivated_users_grace_period_days` if
it has been disabled.
As I'm writing this another change we could make is that we don't change
either of these site settings if we detect that they aren't set to the
default values.
The drive behind this PR is that there is a discourse instance which
relies on staged users as part of their workflow and this setting was
changed by accident via the import script causing users to be deleted
that shouldn't have been.
* DEV: Show warning message when using ember css selectors
When editing the theme css via the admin UI a warning message
will be displayed if it detects that the `#emberXXX` or `.ember-view`
css selectors are being used. These are dynamic selectors that ember
generates, but they can change so they should not be used.
* Update error message text to be more helpful
* Display a warning instead of erroring out
This allows the theme to still be saved, but a warning is displayed.
Updated the tests to check for the error message.
Updated the pre tags css so that it wraps for long messages.
* DEV: Escape backslashes in curl example
We need to escape these backslashes otherwise they get filtered out when
generating the api docs.
* FIX: uniqItems should be uniqueItems
* document user endpoints, allow for empty request/response bodies
* document more user endpoints, improve debugging output if no details are specified
* document some more user endpoints
* minor cleanup
* FIX: flakey tests due to bad regex
- Read in schemas from actual json files instead of a ruby hash. This is
helpful because we will be automatically generating .json schema files
from json responses and don't want to manually write ruby hash schema
files.
- Create a helper method for rspec schema validation tests to dry up code
* DEV: Add schema checking to api doc testing
This commit improves upon rswag which lacks schema checking. rswag
really only checks that the https status matches, but this change adds
in the json-schema_builder gem which also has schema validation.
Now we can define schemas for each of our requests/responses in the
`spec/requests/api/schemas` directory which will make our documentation
specs a lot cleaner.
If we update a serializer by either adding or removing an attribute the
tests will now fail (this is a good thing!). Also if you change the type
of an attribute say from an array to a string the tests will now fail.
This will help significantly with keeping the docs in sync with actual
code changes! Now if you change how an endpoint will respond you will
have to update the docs too in order for the tests to pass. :D
This PR is inspired by:
https://www.tealhq.com/post/how-teal-keeps-their-api-tests-and-documentation-in-sync
* Swap out json schema validator gem
Swapped out the outdated json-schema_builder gem with the json_schemer
gem.
* Add validation fields to schema
In order to have "strict" validation we need to add
`additionalProperties: false` to the schema, and we need to specify
which attributes are required.
Updated the debugging test output to print out the error details if
there are any.
Added GET user by external_id to the api docs.
Fixed `/users/{username}` docs to be `/u/{username}`
Extracted out common user response into a shared helper.
On category create an exception will be thrown on this job because the
save transaction hasn't completed yet and the job cannot find the
category id. To prevent this we can use the rails 6 `after_save_commit`
hook that will fire after the category save transaction has finished for
both update and create actions.
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.
We are switching over to a fork because we are currently on a pinned
version of ember-rails 0.18.5 which is pretty old. Upgrading to the
latest version causes many things to break which isn't really worth the
time to debug while we plan to completely switch over to ember-cli
somewhat soonish. Our fork contains a single cherry-pick commit
https://github.com/emberjs/ember-rails/pull/534
which will fix an issue when running the `rails g migration` command and
it spits out a bunch of deprecation warnings.
There is a request spec that was ignored with the `xit` flag almost a
year ago and every time you generate the api docs with
```
rake rswag:specs:swaggerize
```
it shows the output of this pending test and I guess I finally got sick
of looking at it, so here is a fix for it.
Original Commit: d84c34ad75

It is possible that a user could exist without an email, if so we should
not enqueue a job to download their gravatar.
This commit resolves this error that can occur:
```
Job exception: undefined method `email' for nil:NilClass
/var/www/discourse/app/models/user.rb:1204:in `email'
/var/www/discourse/app/jobs/regular/update_gravatar.rb:12:in `execute'
```
This commit also fixes the original spec which actually was wrong. The
job never enqueued in the original spec and so the gravatar was never
actually updated and the test was checking if the two values were the
same, but they were both null and never updated, so of course they were
the same!
A new test has also been added to make sure the gravatar job isn't
enqueued when a user's email is missing.
We are no longer directly referencing the rb-inotify gem directly in
code. This was just a spec level dependency anyways.
Using `git log -S "Inotify"` resulted in these two commits as usages of
`Inotify`:
- b56b11d96a
- 9cf03b352c
both from 2013, but we no longer are using inotify in
https://github.com/discourse/discourse/blob/master/lib/tasks/autospec.rake
which appears to be the only file that was using it.
Based on this info we can safely remove rb-inotify from the Gemfile.
Just as a side note we still do have a couple of gems that do have
rb-inotify as a dependency: listen, and lru_redux.
* DEV: Switch our fast_xor gem for xorcist
We use the `xor` function as part of password hashing and we want to use
a faster version than the native ruby xor'ing feature so we use a gem
for this.
fast_xor has been abandoned, and xorcist fixed our initial holdup for
switching in https://github.com/fny/xorcist/issues/4
xorcist also has jruby support so we can remove our jruby fallback
logic.
* Move using statement inside of class
These fields are required when using the UI and if `suspend_until`
params isn't used the user never is actually suspended so we should
require these fields when suspending a user.
This commit is addressing an issue where it is possible that there could
be multiple topic timer jobs running to close a topic or a weird race
condition state causing a topic that was just closed to be re-opened.
By removing the logic from the Topic Timer model into the Topic Timer
controller endpoint we isolate the code that is used for setting an
auto-open or an auto-close timer to just that functionality making the
topic timer background jobs safer if multiple are running.
Possibly in the future if we would like this logic back in the model a
refactor will be needed where we actually pass in the auto-close and
auto-open action instead of mixing it with the close and open
action that is currently being passed to the controller.
Because we allow all the other flag types on a deleted post we should be
able to send a pm to the user letting them know why we deleted their
post.
Bug report:
https://meta.discourse.org/t/-/161156
* FIX: Unlike own posts on ownership transfer
If a user has liked a post that has passed the
`post_undo_action_window_mins` system setting window and you transfer ownership
of that post to that user you will be the owner of a post that you have
liked, but cannot unlike resulting in a weird UI behavior. This commit
fixes this issue.
The existing tests didn't check for the timeout window for unliking
posts so I added that in.
I couldn't find a good way to do this logic inside of the guardian class
so rather than duplicating behavior of the `PostActionDestroyer` class
inside of the `PostOwnerChanger` I decided to pass in a "bypass"
variable that could be used to check if the calling class is the
'post_owner_changer' and bypass the guardian instead. I went this route
because the guardian `can_delete_post_action` method has no way of
distinguishing how to allow a user to be able to unlike their own posts
after the timeout window but only on a post owner change.
* use an options hash instead
The rotp gem is currently pinned to version 5.1.0 and this will bump it
up to version 6.0.1.
Follow up to: 85d4370f79
because this issue we were waiting on is now closed:
https://github.com/mdp/rotp/issues/98
Because version 6 is now encoding the params I needed to update the
tests as well.
Currently we have pinned highline to version 1.7.0. This is the gem that
we use to have an interactive command line for tasks like `rake
admin:create`.
Upgrading to the latest version 2.0.3 will remove ruby 2.7 deprecation
warnings.
I'm not sure why *this* gem was pinned. I manually executed a couple of
our rake tasks that use this and everything seems fine.
It's possible that the original topic image is broken in some form, so
we shouldn't try and generate a topic thumbnail for it. The fix will
prevent the generate_topic_thumbnails job being enqueued every time the
topic is viewed.
The category model already has a default value for `color` and
`text_color` so they don't need to be required via the API. The ember UI
already requires that colors be selected.
The name of the category also doesn't need to be required when updating
the category either because we are already passing in the id for the
category we want to change.
These changes improve the api experience because you no longer have to
lookup the category name, color, or text color before updating a single
category attribute. When creating a category the name is still required.

The `/directory_items` route needs to have a .json url, but the rails
url helper `_path` doesn't return the format of the route.
I tried passing in a format options to `directory_items_path`. Which
works in the rails console
```
[8] pry(main)> directory_items_path(params.merge(:format => :json))
=> "/directory_items.json?page=1"
```
but when I added that some logic to the controller it comes out as
```
/directory_items?format=json&page=1
```
(which is actually how I expect it to work based on how you pass in the
format param). Anyways, because I couldn't figure out how to pass a
format to the `_path` helper I just used URI.parse to append `.json`
manually.
The UI prevents users from trying to create tags on topics when they
don't have permission, but if you are trying to add tags to a topic via
the API and you don't have permission before this change it would
silently succeed in creating the topic, but it wouldn't have any tags.
Now a 422 error will be returned with an error message when trying to
create a topic with tags when tagging is disabled or you don't have
enough trust level to add tags to a topic.
