This is unnecessary, as when the temporary key is created
in S3Store we already include the s3_bucket_folder_path, and
the key will always start with temp/ to assist with lifecycle
rules for multipart uploads.
This was affecting Discourse.store.object_from_path,
Discourse.store.signed_url_for_path, and possibly others.

This pull request introduces the endpoints required, and the JavaScript functionality in the `ComposerUppyUpload` mixin, for direct S3 multipart uploads. There are four new endpoints in the uploads controller:
* `create-multipart.json` - Creates the multipart upload in S3 along with an `ExternalUploadStub` record, storing information about the file in the same way as `generate-presigned-put.json` does for regular direct S3 uploads
* `batch-presign-multipart-parts.json` - Takes a list of part numbers and the unique identifier for an `ExternalUploadStub` record, and generates the presigned URLs for those parts if the multipart upload still exists and if the user has permission to access that upload
* `complete-multipart.json` - Completes the multipart upload in S3. Needs the full list of part numbers and their associated ETags which are returned when the part is uploaded to the presigned URL above. Only works if the user has permission to access the associated `ExternalUploadStub` record and the multipart upload still exists.
After we confirm the upload is complete in S3, we go through the regular `UploadCreator` flow, the same as `complete-external-upload.json`, and promote the temporary upload S3 into a full `Upload` record, moving it to its final destination.
* `abort-multipart.json` - Aborts the multipart upload on S3 and destroys the `ExternalUploadStub` record if the user has permission to access that upload.
Also added are a few new columns to `ExternalUploadStub`:
* multipart - Whether or not this is a multipart upload
* external_upload_identifier - The "upload ID" for an S3 multipart upload
* filesize - The size of the file when the `create-multipart.json` or `generate-presigned-put.json` is called. This is used for validation.
When the user completes a direct S3 upload, either regular or multipart, we take the `filesize` that was captured when the `ExternalUploadStub` was first created and compare it with the final `Content-Length` size of the file where it is stored in S3. Then, if the two do not match, we throw an error, delete the file on S3, and ban the user from uploading files for N (default 5) minutes. This would only happen if the user uploads a different file than what they first specified, or in the case of multipart uploads uploaded larger chunks than needed. This is done to prevent abuse of S3 storage by bad actors.
Also included in this PR is an update to vendor/uppy.js. This has been built locally from the latest uppy source at d613b849a6. This must be done so that I can get my multipart upload changes into Discourse. When the Uppy team cuts a proper release, we can bump the package.json versions instead.
When emails were forwarded to a group inbox by the email address
of the group, for example when an email ends up in spam and must
be manually forwarded to the group+site@discoursemail.com address,
the OP of the topic ended up being the group's email address instead
of the sender who originally sent the email to the group inbox.
This commit detects that an email has been forwarded using existing
tools, and if the from address matches one of the group incoming
email addresses, then we look at the forwarded email's from address
and use that instead for the incoming email from address as well as
the staged/regular user used for the Topic.user.
This will make it much cleaner to forward emails into a group inbox,
and will prevent issues with PostAlerter where the OP is double-notified
for these emails.
Currently, pinned topics are ordered by the `bumped_at` column. This behavior is not desired because it gives admins no control over the order of pinned topics. This PR makes pinned topics ordered by the `pinned_at` column. A topic that is pinned last appears first in topic lists. If an admin wants an already pinned topic to appear first in the list of pinned topics, they'll have to unpin that topic and pin it again.
Meta topic: https://meta.discourse.org/t/how-do-i-set-the-order-of-pinned-topics/16935/23?u=osama.
Emails can include the marker in a different language, depending on
site and user settings. The email receiver always looked for the marker
in default language.
Allow admins to configure exceptions to our Rails rate limiter.
Configuration happens in the environment variables, and work with both
IPs and CIDR blocks.
Example:
```
env:
DISCOURSE_MAX_REQS_PER_IP_EXCEPTIONS: >-
14.15.16.32/27
216.148.1.2
```
In 2018 check was added that TL1 welcome message is sent unless user already has BasicBadge granted.
I think we should also check if BasicBadge is even enabled. Otherwise, each time group is assigned to a user and trust level is recalculated, they will receive a welcome message.
This disallows putting URLs in topic titles for TL0 users, which means that:
If a TL-0 user puts a link into the title, a topic featured link won't be generated (as if it was disabled in the site settings)
Server methods for creating and updating topics will be refusing featured links when they are called by TL-0 users
TL-0 users won't be able to put any link into the topic title. For example, the title "Hey, take a look at https://my-site.com" will be rejected.
Also, it improves a bit server behavior when creating or updating feature links on topics in the categories with disabled featured links. Before the server just silently ignored a featured link field that was passed to him, now it will be returning 422 response.
* FIX: Update draft count when sequence is increased
Sometimes users ended up having a draft count higher than the actual
number of drafts.
* FIX: Do not update draft count twice
The call to DraftSequence.next! above already does it.
Inlining secure images with the same name was not possible because they
were indexed by filename. If an email contained two files with the same
name, only the first image was used for both of them. The other file
was still attached to the email.
When the Reply-To header is present for incoming emails we
want to use it instead of the from address. This is usually the
case when forwarding an email via a mailing list into Discourse.
For now we are only using the Reply-To header if the email has
been forwarded via Google Groups, which is why we are checking the
X-Original-From header too. In future we may want to use the Reply-To
header in more cases.
* FEATURE: Onebox can match engines based on the content_type
`FinalDestination` now returns the `content_type` of a resolved URL.
`Oneboxer` passes this value to `Onebox` itself. Onebox engines can now specify a `matches_content_type` regex of content_types that the engine can handle, regardless of the URL.
`ImageOnebox` will match URLs with a content type of `image/png`, `jpg`, `gif`, `bmp`, `tif`, etc.
This will allow images that exist at a URL without a file type extension to be correctly rendered, assuming a valid `content_type` is returned.
When a post is created, the draft sequence is increased and then older
drafts are automatically executing a raw SQL query. This skipped the
Draft model callbacks and did not update user's draft count.
I fixed another problem related to a raw SQL query from Draft.cleanup!
method.
This adds a few different things to allow for direct S3 uploads using uppy. **These changes are still not the default.** There are hidden `enable_experimental_image_uploader` and `enable_direct_s3_uploads` settings that must be turned on for any of this code to be used, and even if they are turned on only the User Card Background for the user profile actually uses uppy-image-uploader.
A new `ExternalUploadStub` model and database table is introduced in this pull request. This is used to keep track of uploads that are uploaded to a temporary location in S3 with the direct to S3 code, and they are eventually deleted a) when the direct upload is completed and b) after a certain time period of not being used.
### Starting a direct S3 upload
When an S3 direct upload is initiated with uppy, we first request a presigned PUT URL from the new `generate-presigned-put` endpoint in `UploadsController`. This generates an S3 key in the `temp` folder inside the correct bucket path, along with any metadata from the clientside (e.g. the SHA1 checksum described below). This will also create an `ExternalUploadStub` and store the details of the temp object key and the file being uploaded.
Once the clientside has this URL, uppy will upload the file direct to S3 using the presigned URL. Once the upload is complete we go to the next stage.
### Completing a direct S3 upload
Once the upload to S3 is done we call the new `complete-external-upload` route with the unique identifier of the `ExternalUploadStub` created earlier. Only the user who made the stub can complete the external upload. One of two paths is followed via the `ExternalUploadManager`.
1. If the object in S3 is too large (currently 100mb defined by `ExternalUploadManager::DOWNLOAD_LIMIT`) we do not download and generate the SHA1 for that file. Instead we create the `Upload` record via `UploadCreator` and simply copy it to its final destination on S3 then delete the initial temp file. Several modifications to `UploadCreator` have been made to accommodate this.
2. If the object in S3 is small enough, we download it. When the temporary S3 file is downloaded, we compare the SHA1 checksum generated by the browser with the actual SHA1 checksum of the file generated by ruby. The browser SHA1 checksum is stored on the object in S3 with metadata, and is generated via the `UppyChecksum` plugin. Keep in mind that some browsers will not generate this due to compatibility or other issues.
We then follow the normal `UploadCreator` path with one exception. To cut down on having to re-upload the file again, if there are no changes (such as resizing etc) to the file in `UploadCreator` we follow the same copy + delete temp path that we do for files that are too large.
3. Finally we return the serialized upload record back to the client
There are several errors that could happen that are handled by `UploadsController` as well.
Also in this PR is some refactoring of `displayErrorForUpload` to handle both uppy and jquery file uploader errors.
Prior to this fix, post whisperer in personal messages are revealed in
the topic's participants list even though non-staff users are unable to
see the whisper.
Using an invalid value was allowed. This commit tries to automatically
fix the color by adding missing # symbol or will show an error to the
user if it is not possible and it is not a CSS color either.
Configuring staged users to watch categories and tags is a way to sign
them up to get many emails. These emails may be unwanted and get marked
as spam, hurting the site's email deliverability.
Users can opt-in to email notifications by logging on to their
account and configuring their own preferences.
If staff need to be able to configure these preferences on behalf of
staged users, the "allow changing staged user tracking" site setting
can be enabled. Default is to not allow it.
