https://meta.discourse.org/t/improving-mailman-email-parsing/253041
When mirroring a public mailling list which uses mailman, there were some cases where the incoming email was not associated to the proper user.
As it happens, for various (undertermined) reasons, the email from the sender is often not in the `From` header but can be in any of the following headers: `Reply-To`, `CC`, `X-Original-From`, `X-MailFrom`.
It might be in other headers as well, but those were the ones we found the most reliable.
Currently processing emails that are blank or have a nil value for the mail will cause several errors.
This update allows emails with blank body or missing sender to log the blank email error to the mail logs rather than throwing an error.
### What is this change?
The lounge category was replaced with the general category in https://github.com/discourse/discourse/pull/18097.
However, there are still a few references to the lounge category in code. In particular, `Category#seeded?` is erroring out in production looking for `SiteSetting.lounge_category_id`.
* FIX: Displaying the wrong number of minimum tags in the composer
When the minimum number of tags set for the category is larger than the minimum number of tags
set in the category tag-groups, the composer was displaying the wrong value.
This commit fixes the value displayed in the composer to show the max value between the required
for the category and the tag-groups set for the category.
This bug was reported on Meta in https://meta.discourse.org/t/tags-from-multiple-tag-groups-required-only-suggest-select-at-least-one-tag/263817
* FIX: Limiting tags in categories not working as expected
When a category was restricted to a tag group A, which was set to only allow
one tag from the group per topic, selecting a tag belonging only to A returned
other tags from A that also belonged to other group/s (if any).
Example:
Tag group A: alpha, beta, gamma, epsilon, delta
Tag group B: alpha, beta, gamma
Both tag groups set to only allow one tag from the group per topic.
If Category 1 was set to only allow tags from the tag group A, and the first tag
selected was epsilon, then, because they also belonged to tag group B, the tags
alpha, beta, and gamma were still returned as valid options when they should not be.
This commit ensures that once a tag from a tag group that restricts its tags to
one per topic is selected, no other tag from this group is returned.
This bug was reported on Meta in https://meta.discourse.org/t/limiting-tags-to-categories-not-working-as-expected/263143.
* FIX: Moving topics does not prompt to add required tag for new category
When a topic moved from a category to another, the tag requirements
of the new category were not being checked.
This allowed a topic to be created and moved to a category:
- that limited the tags to a tag group, with the topic containing tags
not allowed.
- that required N tags from a tag group, with the topic not containing
the required tags.
This bug was reported on Meta in https://meta.discourse.org/t/moving-tagged-topics-does-not-prompt-to-add-required-tag-for-new-category/264138.
* FIX: Editing topics with tag groups from parents allows incorrect tagging
When there was a combination between parent tags defined in a tag group
set to allow only one tag from the group per topic, and other tag groups
relying on this restriction to combine the children tag types with the
parent tag, editing a topic could allow the user to insert an invalid
combination of these tags.
Example:
Automakers tag group: landhover, toyota
- group set to limit one tag from the group per topic
Toyota models group: land-cruiser, hilux, corolla
Landhover models group: evoque, defender, discovery
If a topic was initially set up with the tags toyota, land-cruiser it was
possible to edit it by removing the tag toyota and adding the tag landhover
and other landhover model tags like evoque for example.
In this case, the topic would end up with the tags toyota, land-cruiser,
landhover, evoque because Discourse will automatically insert the
missing parent tag toyota when it detects the tag land-cruiser.
This combination of tags would violate the restriction specified in
the Automakers tag group resulting in an invalid combination of tags.
This commit enforces that the "one tag from the group per topic"
restriction is verified before updating the topic tags and also
make sure the verification checks the compatibility of parent tags that
would be automatically inserted.
After the changes, the user will receive an error similar to:
The tags land-cruiser, landhover cannot be used simultaneously.
Please include only one of them.
TopicsFilter is meant to generate a query scope from a given string so
we don't really need to ensure any ordering outside of the supported
order filters.
- Update welcome topic copy
- Edit the welcome topic automatically when the title or description changes
- Remove “Create your Welcome Topic” banner/CTA
- Add "edit welcome topic" user tip
After this change, in order to join a chat channel, a user needs to be in a group with at least “Reply” permission for the category. If the user only has “See” permission, they are able to preview the channel, but not join it or send messages. The auto-join function also follows this new restriction.

We were giving topics with repeated words extra weight in search index.
This meant that it was trivial to stuff words into title to dominate in search
given we search for exact title matches first.
The following tweak means that:
`invite invited invites`
and
`invite some stuff`
Both rank the same for title searching.
Titles are short and punchy, duplicating words should not give special
weight.
Requires a full reindex to take effect.
A category's slug can be encoded when
`SiteSetting.slug_generation_method` has been set to "encoded". As a
result, we have to support non ASCII characters as well.
This commit adds support for excluding categories when using the
`category:` filter with the `-` prefix. For example,
`-category:category-slug` will exclude all topics that belong to the
category with slug "category-slug" and all of its sub-categories.
To only exclude a particular category and not all of its sub-categories,
the `-` prefix can be used with the `=` prefix. For example,
`-=category:category-slug` will only exclude topics that belong to the
category with slug "category-slug". Topics in the sub-categories of
"category-slug" will still be included.
This amends it so our cached counting reliant specs run in synchronize mode
When running async there are situations where data is left over in the table
after a transactional test. This means that repeat runs of the test suite
fail.
Specifying more than two tag names when using the `tag:` filter was not
working because of a bug in the code where only the first two value in
the `tag:` filter was being selected.
What is the problem?
Consider the following timeline:
1. OP starts a topic.
2. Troll responds snarkily.
3. Flagger flags the post as “inappropriate”.
4. Admin agrees and hides the post.
5. Troll ninja-edits the post within the grace period, but still snarky.
6. Flagger flags the post as inappropriate again.
The current behaviour is that the flagger is met with an error saying the post has been reviewed and can't be flagged again for the same reason.
The desired behaviour is after someone has edited a post, it should be flaggable again.
Why is this happening?
This is related to the ninja-edit feature, where within a set grace period no new revision is created, but a new revision is required to flag the same post for the same reason.
So essentially there is a window between the naughty corner cooldown where a flagged post can't be edited, and the ninja-edit grace period, where an edit can be made without a new revision. Posts that are edited within this window can't be re-flagged by the same user.
|-----------------|-------------------------------|
^ Flag accepted | ~~~~~~~~~~~~~ 🥷🏻 ~~~~~~~~~~~~ |
| ^ Editing grace period over
^ Naughty corner cooldown over
How does this fix it?
We already create a new revision when ninja-editing a post with a pending flag. The issue above happens only in the case where the flag is already accepted.
This change extends the existing behaviour so that a new revision is created when ninja-editing any flagged post, regardless of the status of the flag. (Deleted flags excluded.)
This should also help with posterity, avoiding situations where a successfully flagged post looks innocuous in the history because it was ninja-edited, and vice versa.
This header is used by Microsoft Exchange to indicate when certain types of
autoresponses should not be generated for an email.
It triggers our "is this mail autogenerated?" detection, but should not be used
for this purpose.
This allows multiple ordering to be specified by using a comma seperated string.
For example, `order:created,views` would order the topics by
`Topic#created_at` and then `Topic#views.
An older change about optimising images caused the selector that adds lightboxing not to apply on quoted images. This fixes that. The selector is now not applicable as optimisation occurs in a separate place.
This change allows quoted images to be opened in a lightbox.
This new modifier can be used by plugins to modify search ordering.
Specifically plugins such as discourse_solved can amend search ordering
so solved topics bump to the top.
Also correct edge case where low and high sort priority categories did not
order correctly when it came to closed/archived
This commit adds support for the following ordering filters:
1. `order:activity` which orders the topics by `Topic#bumped_at` in descending order
2. `order:activity-asc` which orders the topics by `Topic#bumped_at` in ascending order
3. `order:latest-post` which orders the topics by `Topic#last_posted_at` in descending order
4. `order:latest-post-asc` which orders the topics by `Topic#last_posted_at` in ascending order
5. `order:created` which orders the topics by `Topic#created_at` in descending order
6. `order:created-asc` which orders the topics by `Topic#created_at` in ascending order
7. `order:views` which orders the topics by `Topic#views` in descending order
8. `order:views-asc` which orders the topics by `Topic#views` in ascending order
9. `order:likes` which orders the topics by `Topic#likes` in descending order
10. `order:likes-asc` which orders the topics by `Topic#likes` in ascending order
11. `order:likes-op` which orders the topics by `Post#like_count` of the first post in the topic in descending order
12. `order:likes-op-asc` which orders the topics by `Post#like_count` of the first post in the topic in ascending order
13. `order:posters` which orders the topics by `Topic#participant_count` in descending order
14. `order:posters-asc` which orders the topics by `Topic#participant_count` in ascending order
15. `order:category` which orders the topics by `Category#name` of the topic's category in descending order
16. `order:category-asc` which orders the topics by `Category#name` of the topic's category in ascending order
Multiple order filters can be composed together and the order of ordering is applied based on the position of the filter
in the query string. For example, `order:views order:created` will order the topics by `Topic#views` in descending order
and then order the topics by `Topics#created_at` in descending order.
This commit adds support for the following date filters:
1. `activity-before:<YYYY-MM-DD>` which filters for topics that have been bumped at or before given date
2. `activity-after:<YYYY-MM-DD>` which filters for topics that have been bumped at or after given date
3. `created-before:<YYYY-MM-DD>` which filters for topics that have been created at or before given date
4. `created-after:<YYYY-MM-DD>` which filters for topics that have been created at or after given date
5. `latest-post-before:<YYYY-MM-DD>` which filters for topics with the
latest post posted at or before given date
6. `latest-post-after:<YYYY-MM-DD>` which filters for topics with the
latest post posted at or after given date
If the filter has an invalid value, i.e string that cannot be converted
into a proper date in the `YYYY-MM-DD` format, the filter will be ignored.
If either of each filter is specify multiple times, only the last
occurrence of each filter will be taken into consideration.
Large or broken images are removed from oneboxes, but sometimes images
were removed when they were oneboxed too. The reason is that images can
be oneboxed by the AllowlistedGenericOnebox or ImageOnebox and only
AllowlistedGenericOnebox was handled correctly.
When revising a post, if the topic that post belonged to did not have a category attached it would error with
> NoMethodError (undefined method `read_restricted' for nil:NilClass)
- Move the old '`define_include_method`' arg to a `respect_plugin_enabled` kwarg
- Introduce an `include_condition` kwarg which can be passed a lambda with inclusion logic. Lambda will be run via `instance_exec` in the context of the serializer instance
This is backwards compatible - old-style invocations will trigger a deprecation message

Update chat and poll plugins to new pattern
Responding to negative behaviour tends to solicit more of the same. Common wisdom states: "don't feed the trolls".
This change codifies that advice by introducing a new nudge when hitting the reply button on a flagged post. It will be shown if either the current user, or two other users (configurable via a site setting) have flagged the post.
* DEV: Support `likes-(min:max):<count>` on `/filter` route
This commit adds support for the following filters:
1. `likes-min`
2. `likes-max`
3. `views-min`
4. `views-max`
5. `likes-op-min`
6. `likes-op-max`
If the filter has an invalid value, i.e string that cannot be converted
into an integer, the filter will be ignored.
If either of each filter is specify multiple times, only the last
occurrence of each filter will be taken into consideration.
This commit adds support for the `posters-min:<count>` and
`posters-max:<count>` filters for the topics filtering query language.
`posters-min:1` will filter for topics with at least a one poster while
`posters-max:3` will filter for topics with a maximum of 3 posters.
If the filter has an invalid value, i.e string that cannot be converted
into an integer, the filter will be ignored.
If either of each filter is specify multiple times, only the last
occurence of each filter will be taken into consideration.
This commit adds support for the `posts-min:<count>` and

`posts-max:3` will filter foor topics with a maximum of 3 posts.
If the filter has an invalid value, i.e string that cannot be converted

When we "pull hotlinked images" on onebox images, they are added to the uploads table and their dominant color is calculated. This commit adds the data to the HTML so that it can be used by the client in the same way as non-onebox images. It also adds specific handling to the new `discourse-lazy-videos` plugin.
This commit adds support for the `created-by:<username>` query filter
which will return topics created by the specified user. Multiple
usernames can be specified by comma seperating the usernames like so:
`created-by:username1,username2`. This will filter for topics created by
either of the specified users. Multiple `created-by:<username>` can also
be composed together. `created-by:username1 created-by:username2` is
equivalent to `created-by:username1,username2`.
This was inadvertently removed in 4c46c7e. In very specific scenarios,
this could be used execute arbitrary JavaScript.
Only affects instances where SVGs are allowed as uploads and CDN is not
configured.
Previously, Discourse's password hashing was hard-coded to a specific algorithm and parameters. Any changes to the algorithm or parameters would essentially invalidate all existing user passwords.
This commit introduces a new `password_algorithm` column on the `users` table. This persists the algorithm/parameters which were use to generate the hash for a given user. All existing rows in the users table are assumed to be using Discourse's current algorithm/parameters. With this data stored per-user in the database, we'll be able to keep existing passwords working while adjusting the algorithm/parameters for newly hashed passwords.
Passwords which were hashed with an old algorithm will be automatically re-hashed with the new algorithm when the user next logs in.
Values in the `password_algorithm` column are based on the PHC string format (https://github.com/P-H-C/phc-string-format/blob/master/phc-sf-spec.md). Discourse's existing algorithm is described by the string `$pbkdf2-sha256$i=64000,l=32$`
To introduce a new algorithm and start using it, make sure it's implemented in the `PasswordHasher` library, then update `User::TARGET_PASSWORD_ALGORITHM`.
This commit adds support for the `in:<topic notification level>` query
filter. As an example, `in:tracking` will filter for topics that the
user is watching. Filtering for multiple topic notification levels can
be done by comma separating the topic notification level keys. For
example, `in:muted,tracking` or `in:muted,tracking,watching`.
Alternatively, the user can also compose multiple filters with `in:muted
in:tracking` which translates to the same behaviour as
`in:muted,tracking`.
This commit adds support for the `in:pinned` filter to the topics filtering
query language. When the filter is present, it will filter for topics
where `Topic#pinned_until` is greater than `Topic#pinned_at`.
This adds a SiteSetting, which when enabled, creates a small_action post for tag/category changes to the topic. It uses `topic.add_moderator_post, and passes raw text in, to describe the change.
Before this commit, composing multiple category filters with a query such as category:category1 and category:category2 would not return any results. This is because we were filtering for topics that belonged to both category1 and category2, which is impossible since a topic can only belong to a single category.
With this commit, specifying a query like category:category1 category:category2 will now translate to filtering for topics that belong to either the category1 or category2 category.
Invite only and Discourse connect could not be enabled at the same time
because of some legacy reason. This is a follow up commit to ce04db8,
355d51a and 40f6ceb.
This commit adds support for filtering for topics in specific
subcategories via the categories filter query language.
For example: `category:documentation:admins` will filter for topics and
subcategory topics in
the category with slug "admins" whose parent category has the slug
"documentation".
The `=` prefix can also be used such that
`=category:documentation:admins` will exclude subcategory topics of the
category with slug "admins" whose parent category has the slug
"documentation".
On the `/filter` route, the categories filtering query language is now
supported in the input per the example provided below:
```
category:bug => topics in the bug category AND all subcategories
=category:bug => topics in the bug category excluding subcategories
category:bug,feature => allow for categories either in bug or feature
=category:bug,feature => allow for exact categories match excluding sub cats
categories: => alias for category
```
Currently composing multiple category filters is not supported as we
have yet to determine what behaviour it should result in. For example,
`category:bug category:feature` would now return topics that are in both
the `bug` and `feature` category but it is not possible for a topic to
belong to two categories.
Add a modifier that will allow us to tune the results returned by suggested.
At the moment the modifier allows us to toggle including random results.
This was created for the discourse-ai module. It needs to switch off random
results when it returns related topics.
Longer term we can use it to toggle unread/new and other aspects.
This also demonstrates how to test the contract when adding modifiers.
Similar to the _map added for group_list SiteSettings in
e62e93f83a, this commit adds
the same extension for simple and compact `list` type SiteSettings,
so developers do not have to do the `.to_s.split("|")` dance
themselves all the time.
For example:
```
SiteSetting.markdown_linkify_tlds
=> "com|net|org|io|onion|co|tv|ru|cn|us|uk|me|de|fr|fi|gov|ddd"
SiteSetting.markdown_linkify_tlds_map
=> ["com", "net", "org", "io", "onion", "co", "tv", "ru", "cn", "us", "uk", "me", "de", "fr", "fi", "gov"]
```
There is no need to validate the user's emails when
promoting/demoting their trust level, this can cause
issues in things like Jobs::Tl3Promotions, we don't
need to fail in that case when all we are doing is changing
trust level.
Introduces a new API for plugin data modification without class-based extension overhead.
This commit introduces a new API that allows plugins to modify data in cases where they return different data rather than additional data, as is common with filtered_registers in DiscoursePluginRegistry. This API removes the need for defining class-based extension points.
When a plugin registers a modifier, it will automatically be called if the plugin is enabled. The core will then modify the parameter sent to it using the block registered by the plugin:
```ruby
DiscoursePluginRegistry.register_modifier(plugin_instance, :magic_sum_modifier) { |a, b| a + b }
sum = DiscoursePluginRegistry.apply_modifier(:magic_sum_filter, 1, 2)
expect(sum).to eq(3)
```
Key features of these modifiers:
- Operate in a stack (first registered, first called)
- Automatically disabled when the plugin is disabled
- Pass the cumulative result of all block invocations to the caller
The following are the changes being introduced in this commit:
1. Instead of mapping the query language to various query params on the
client side, we've decided that the benefits of having a more robust
query language far outweighs the benefits of having a more human readable query params in the URL.
As such, the `/filter` route will just accept a single `q` query param
and the query string will be parsed on the server side.
1. On the `/filter` route, the tags filtering query language is now
supported in the input per the example provided below:
```
tags:bug+feature tagged both bug and feature
tags:bug,feature tagged either bug or feature
-tags:bug+feature excluding topics tagged bug and feature
-tags:bug,feature excluding topics tagged bug or feature
```
The `tags` filter can also be specified multiple
times in the query string like so `tags:bug tags:feature` which will
filter topics that contain both the `bug` tag and `feature` tag. More
complex query like `tags:bug+feature -tags:experimental` will also work.
This change sets the ground work for allowing us to filter topics list
by tags in the following ways:
1. Filter for topics that matches all tags in a given set of tags
2. Filter for topics that matches any tags in a given set of tags
3. Exclude topics that matches all tags in a given set of tags
4. Exclude topics that matches any tags in a given set of tags
When we renamed the `default_categories_regular` to `default_categories_normal` we missed a site setting validation method. It allowed the duplicate category ids in `default_categories_normal` site setting and caused the problem in user registration process.

When setting the ACL for optimized images after setting the
ACL for the linked upload (e.g. via the SyncACLForUploads job),
we were using the optimized image path as the S3 key. This worked
for single sites, however it would fail silently for multisite
sites since the path would be incorrect, because the Discourse.store.upload_path
was not included.
For example, something like this:
somecluster1/optimized/2X/1/3478534853498753984_2_1380x300.png
Instead of:
somecluster1/uploads/somesite1/2X/1/3478534853498753984_2_1380x300.png
The silent failure is still intentional, since we don't want to
break other things because of ACL updates, but now we will update
the ACL correctly for optimized images on multisite sites.
Our SafeMigrate system is designed to prevent tables/columns being dropped in pre-deploy migrations. Its regex-based detection was triggering incorrectly on `ALTER COLUMN DROP NOT NULL`.
There was a lot of duplication in the svg parsing and coercion code. This reduces that duplication and causes svg sprite parsing to happen earlier so that more computation is cached.
Our schema allows `category.topic_id` to be NULL. Null values shouldn't actually happen in production, but it is very common in tests because `Fabricate(:category)` skips creating the definition topic to improve performance. Before this commit, a NULL category.topic_id would cause all subcategory topics to be excluded from a TopicQuery result. This is because, in postgres, `NULL <> anything` is falsy. Instead, we can use `IS DISTINCT FROM`, which will return true when NULL is compared to a non-NULL value.
Why is this change required?
Prior to this change, we would list all group messages that a user
has access to in the user menu messages notifications panel dropdown.
However, this did not respect the topic's notification level setting and
group messages which the user has set to 'normal' notification level were
being displayed
What does this commit do?
With this commit, we no longer display all group messages that a user
has access to. Instead, we only display group messages that a user is
watching in the user menu messages notifications panel dropdown.
Internal Ref: /t/94392
Follow up to 4d2a95ffe6. Sometimes
due to the original UploadReference migration or other issues,
multiple UploadReference records can have the exact same
created_at date and time. To tiebreak and correct the SQL order
when this happens, we can add a secondary `id ASC` ordering
when we check for the first upload reference.
Similar spirit to e195e6f614,
this moves the Bookmarkable registration to DiscoursePluginRegistry
so plugins which are not enabled do not register additional
bookmarkable classes.
When a theme setting of type `upload` has a default upload, it should return the URL of the specified default upload until a custom upload is used for the setting. However, currently this isn't the case and we get null instead of the default upload URL.
The reason for this is because the `super` method of `#value` already returns the default upload URL (if there's one), so we can't pass that to `cdn_url` which expects an upload ID:
c961dcc757/lib/theme_settings_manager.rb (L212)
This commit fixes the bug by skipping the call to `cdn_url` when we fallback to the default upload for the setting value.

Follow up to 098ab29d41. Since
we just used a `cattr_reader` on `About` this was not safe
for multisite, since some sites could have the chat plugin
enabled and some may not. Using `DiscoursePluginRegistry` gets
around this issue, and makes it so the chat stats only show
for a site if `chat_enabled` is true.
Sometimes we get Maps URL containing a zoom level as a float (17.5z and
not 17z) but this doesn’t work with our current onebox implementation.
While Google accepts those float zoom levels, it removes automatically
the floating part in the URL (thus when visiting a Maps URL containing
17.5z, the URL will be rewritten shortly after as 17z). When putting a
float zoom level in an embedded URL, this actually breaks (Maps API
returns a 400 error).
This patch addresses the issue by allowing the onebox engine to match on
a zoom level expressed as a float but we only keep the integer part thus
rendering properly maps.
