The `EXECUTE FUNCTION` syntax for `CREATE TRIGGER` statements was introduced in PostgreSQL 11. We need to replace `EXECUTE FUNCTION` with `EXECUTE PROCEDURE` in order to be able to restore backups created with PG12 on PG10.
Fixed bugs, added specs, extracted the upload downsizing code to a class, added support for non-S3 setups, changed it so that images aren't downloaded twice.
This code has been tested on production and successfully resized ~180k uploads.
Includes:
* DEV: Extract upload downsizing logic
* DEV: Add support for non-S3 uploads
* DEV: Process only images uploaded by users
* FIX: Incorrect usage of `count` and `exist?` typo
* DEV: Spec S3 image downsizing
* DEV: Avoid downloading images twice
* DEV: Update filesizes earlier in the process
* DEV: Return false on invalid upload
* FIX: Download images that currently above the limit (If the image size limit is decreased, then there was no way to resize those images that now fall outside the allowed size range)
* Update script/downsize_uploads.rb (Co-authored-by: Régis Hanol <regis@hanol.fr>)
This came in as a request on meta to include the raw field in the post
webhook serializer.
https://meta.discourse.org/t/-/49045/55?u=blake
Including this field can prevent needing to make a 2nd API request to
get the raw field of a post.
It would be handy down the road if we updated the webhook ui to specify
fields or arguments that you wanted to be included in the serialized
data, but most requests I've seen to update the serializers have been
valid requests that are good to add anyways, so I don't think we have
reached that point yet.
FIX: prevent re-flagging when we have reviewed flags before
Fixes an edge case where a review can be reflagged when:
User flags as inappropriate.
Moderator rejects the flag.
Another user re-flags the post as spam.
Before, anyone was able to re-flag as inappropriate despite it being flagged
previously. With this, users are unable to re-flag for the same reason
regardless of reviewable status.
This test lasted about 7 years prior to it becoming flaky.
Today ... for whatever reason the test suite created 100 users
prior to running this spec. So the new user becomes user id 101
And... lo and behold:
```
1) PostSerializer a hidden post with add_raw enabled a hidden post shows the raw post only if authorized to see it
Failure/Error: expect(serialized_post_for_user(Fabricate(:user))[:raw]).to eq(nil)
expected: nil
got: "Raw contents of the post."
(compared using ==)
# ./spec/serializers/post_serializer_spec.rb:127:in `block (4 levels) in <main>'
```
We removed pry-nav a while back because it is not up to date with pry but it is super useful. Luckily pry-byebug is here to save us all from Satan's power.
To get this to work you need to add the following to your $HOME/.pryrc file.
```
if defined?(PryByebug)
Pry.commands.alias_command 'c', 'continue'
Pry.commands.alias_command 's', 'step'
Pry.commands.alias_command 'n', 'next'
Pry.commands.alias_command 'f', 'finish'
end
Pry::Commands.command /^$/, "repeat last command" do
pry_instance.run_command Pry.history.to_a.last
end
```
The require-ing of pry, pry-rails, and pry-byebug in specs is controlled by the IMPROVED_SPEC_DEBUGGING flag (disabled by default).
Adds new hidden site settings for rate limits:
30 for logged in users, 15 for anon
Adds an anon cache for searching, caches results of searches for 1 minute
Allow limiting the number of migrations to do at once, both to do migrations that
have impact limited to multiple off-peak usage hours to reduce user impact from
a migration, and to allow tests that do only a very small number for test
purposes. ("Give me a ping, Vasili. One ping only, please.")
Looks like some html elements like `aside` and `section` will throw an error
when checking if they are inline or not. The commit simply handles
```
Job exception: undefined method `inline?' for nil:NilClass
```
and adds a test for it.
Moves the most important checks into a linter. It gets executed by Lefthook as well as the docker rake task and Github actions. Doing those checks in rspec takes too long and it produces errors when the discourse:test Docker image contains old, invalid locale files.
Discourse needs a bunch of data preloaded before it can start up.
Normally we throw blobs of this into the HTML document that is requested
but in some cases that's awkward to retrieve.
For example with Ember CLI you have a separate javascript application
that needs to make its own HTML.
This API endpoint returns a JSON object with all the data Discourse needs to
bootstrap and start up.
In some restricted setups all JS payloads need tight control.
This setting bans admins from making changes to JS on the site and
requires all themes be whitelisted to be used.
There are edge cases we still need to work through in this mode
hence this is still not supported in production and experimental.
Use an example like this to enable:
`DISCOURSE_WHITELISTED_THEME_REPOS="https://repo.com/repo.git,https://repo.com/repo2.git"`
By default this feature is not enabled and no changes are made.
One exception is that default theme id was missing a security check
this was added for correctness.
If `default email digest frequency` was set to "Never", users would get
a `digest_after_minutes` set to `nil` which triggered this error
in the logs if/when the site eventually changed that setting and
enabled digests:
```
NoMethodError (undefined method `>=' for nil:NilClass)
/var/www/discourse/app/mailers/user_notifications.rb:227:in `digest'
```
* FEATURE: notify admins about old credentials
Security and API keys should be renewed periodically.
This additional notification should help admins keep their Discourse safe and secure.
Previously the pull hotlinked images job was skipped after system edits. This ensured that we never had an infinite loop of system-edit/pull-hotlinked/system-edit/pull-hotlinked etc.
A side effect was that edits made by system for any other reason (e.g. API, removing full quotes) would prevent pulling hotlinked images. This commit removes the system edit check, and replaces it with another method to avoid an infinite job scheduling loop.
Hostname can vary per-site on a multisite cluster, so this change requires converting the compiler_version from a constant into a class method which is evaluated at runtime. The value is stored in the theme DistributedCache, so performance impact should be negligible.
We previously did not account for completely untagged topics when
looking at muted tags, this caused new/unread counts to be off if
1. You had muted tags
2. You had an unread/new topic
3. This topic had no tags
This feature allows certain plugins to output tag information
to topic tracking state, this allows per tag stats which can be
used by sidebars and other plugins that need per tag stats
Not enabled by default cause this would add cost to a critical
query
* DEV: new S3 backup layout
Currently, with $S3_BACKUP_BUCKET of "bucket/backups", multisite backups
end up in "bucket/backups/backups/dbname/" and single-site will be in
"bucket/backups/".
Both _should_ be in "bucket/backups/dbname/"
- remove MULTISITE_PREFIX,
- always include dbname,
- method to move to the new prefix
- job to call the method
* SPEC: add tests for `VacateLegacyPrefixBackups` onceoff job.

When running jobs in tests, we use `Jobs.run_immediately!`. This means that jobs are run synchronously when they are enqueued. Jobs sometimes enqueue other jobs, which are also executed synchronously. This means that the outermost job will block until the inner jobs have finished executing. In some cases (e.g. process_post with hotlinked images) this can lead to a deadlock.
This commit changes the behavior slightly. Now we will never run jobs inside other jobs. Instead, we will queue them up and run them sequentially in the order they were enqueued. As a whole, they are still executed synchronously. Consider the example
```ruby
class Jobs::InnerJob < Jobs::Base
def execute(args)
puts "Running inner job"
end
end
class Jobs::OuterJob < Jobs::Base
def execute(args)
puts "Starting outer job"
Jobs.enqueue(:inner_job)
puts "Finished outer job"
end
end
Jobs.enqueue(:outer_job)
puts "All jobs complete"
```
The old behavior would result in:
```
Starting outer job
Running inner job
Finished outer job
All jobs complete
```
The new behavior will result in:
```
Starting outer job
Finished outer job
Running inner job
All jobs complete
```
Fixes a regression in
e8fb9d4066
which caused a bug where you couldn't send a message to a group that
contained an Uppercase letter. Added a test case for this.
Bug report: https://meta.discourse.org/t/-/152999
* FIX: add X-Robots-Tag header for check_xhr-covered GET actions, too
see https://meta.discourse.org/t/missing-x-robots-tag/152593/3 for context
* test: a spec making sure X-Robots-Tag header is present when needed
/groups path responds to anonymous requests and doesn't skip `check_xhr` method, so we can use it here.
It might happen that some User records have no associated primary emails.
In which case we don't ever want to send them a digest.
Also added a new "user_email_no_email" skipped email log to ensure these cases
are properly handled and surfaced.
* FEATURE: notify admins about old credentials
Security and API keys should be renewed periodically.
This additional notification should help admins keep their Discourse safe and secure.
Previously we had a partial fix in place where non human users
were not allowed draft sequences, this left edges around where non
human users asked for drafts yet had none.
For example system could already have a few drafts in place.
This also removes and extensibility point we added that is not in use
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
* We now have a site setting "topic_excerpt_maxlength" that is used when the OP is created or revised to generate a topic excerpt.
* However, posts created before this setting was introduced cannot benefit from this change unless they are revised, and if the topic excerpt length setting is changed that situation is also not covererd.
* This PR makes a change to rebake! to update the topic excerpt IF the post is the OP.
If a user is created with an id of 999, a `upload.user_id ==
user_avatar.user_id` will return true. This fix increases the id of the
upload to something that we will not hit in the foreseeable future.
Adds a new topic_excerpt_maxlength site setting.
* When topic excerpt is requested for a post, use the new topic_excerpt_maxlength site setting to limit the size of the excerpt
* Remove code for getting/setting Post.excerpt_size as it is not used anywhere
* FIX: Emit web hooks for flags
* FEATURE: Remove 'flag' web hook in favor of 'reviewable' web hook
* FEATURE: Remove 'queued post' web hook in favor of 'reviewable' web hook
* FIX: Do not set a default value for web hooks with no events
In some cases, between Discourse forums the hostname of a URL could match if they are hosting S3 files on the same bucket but the S3 bucket path might not. So e.g. https://testbucket.somesite.com/testpath/some/file/url.png vs https://testbucket.somesite.com/prodpath/some/file/url.png. So has_been_uploaded? was returning true for the second URL, even though it may have been uploaded on a different Discourse forum.
This is a very rare case but must be accounted for, because this impacts UrlHelper.is_local which mistakenly thinks the file has already been downloaded and thus allows the URL to be cooked, where we want to return the full URL to be downloaded using PullHotlinkedImages.
* FIX: randomize file name when created from fixtures
When a temporary file is created from fixtures it should have a unique name.
It is to prevent a collision in parallel specs evaluation
* FIX: use /tmp/pid folder to keep fixture files
Signed S3 URLs are valid for 15 seconds, so we can safely allow the browser to cache them for 10 seconds. This should help with large numbers of requests when composing a post with many images.
PG already handles English stop words, the list in cppjieba is
bigger than the list PG uses, which in turn causes confusion cause
words such as "volume" are stripped using cppijieba stop word list
We will follow up with another commit here to apply the Chinese
word stopwords, but for now to eliminate the confusion we are
skipping applying the stopword list when the dictionary in PG is
in English.
* DEV: Add framework for filtered plugin registers
Plugins often need to add values to a list, and we need to filter those lists at runtime to ignore values from disabled plugins. This commit provides a re-usable way to do that, which should make it easier to add new registers in future, and also reduce repeated code.
Follow-up commits will migrate existing registers to use this new system
* DEV: Migrate user and group custom field APIs to plugin registry
This gives us a consistent system for checking plugin enabled state, so we are repeating less logic. API changes are backwards compatible
* DEV: Standardize table sorting verbiage
This commit creates a common component that tables can use to make their
headers sortable. This commit also standardizes on using `desc` as the
default and passing in the `asc=true` flag to adjust the sorting
direction.
* Add deprecation warnings
Adds deprecation warnings if using previous params and maintains
backwards compatibility. Set the default sort value for group members to
be asc.
* switch group requests to use common table-header-toggle
* update fixture
* FIX: randomly falling user_spec
When we evaluate `update_last_seen!` we relay on Redis to not run that code too often
https://github.com/discourse/discourse/blob/master/app/models/user.rb#L753
The problem is that not all specs which are running `update_last_seen!` are not cleaning after themselves
For examples specs in that block https://github.com/discourse/discourse/blob/master/spec/models/user_spec.rb#L901
So it can be replicated when you run a few times
`bundle exec rspec ./spec/models/user_spec.rb -e "should not update the first seen value if it doesn't exist" -e "should have 0 for days_visited"`
We should delete Redis key after each spec which is evaluating `update_last_seen!`
* PERF: Dematerialize topic_reply_count
It's only ever used for trust level promotions that run daily, or compared to 0. We don't need to track it on every post creation.
* UX: Add symbol in TL3 report if topic reply count is capped
* DEV: Drop user_stats.topic_reply_count column
Use a helper method to simplify creating a new register. Previously this would require creating lots of different methods manually, and adding every register to the clear/reset functions
Previously the code was very race condition prone leading to
odd failures in production
It was re-written in raw SQL to avoid conditions where rows
conflict on inserts
There is no clean way in ActiveRecord to do:
Insert, on conflict do nothing and return existing id.
This also increases test coverage, we were previously not testing
the code responsible for crawling external sites directly
This commit prevents a 500 error from occurring if someone is trying to
setup their discourse instance as a sso provider and they don't pass in
a `return_sso_url` in their payload.
We were getting errors like this in Reviewables in some cases:
```
ActiveRecord::StatementInvalid (PG::AmbiguousColumn: ERROR: column reference "category_id" is ambiguous
LINE 4: ...TRUE) OR (reviewable_by_group_id IN (NULL))) AND (category_i...
```
The problem that was making everything go boom is that plugins can add their own custom filters for Reviewables. If one is doing an INNER JOIN on topics, which has its own category_id column, we would get the above AmbiguousColumn error. The solution here is to just make all references to the reviewable columns in the list_for and viewable_by code prefixed by the table name e.g. reviewables.category_id.
