This PR introduces a new `enable_experimental_backup_uploads` site setting (default false and hidden), which when enabled alongside `enable_direct_s3_uploads` will allow for direct S3 multipart uploads of backup .tar.gz files.
To make multipart external uploads work with both the S3BackupStore and the S3Store, I've had to move several methods out of S3Store and into S3Helper, including:
* presigned_url
* create_multipart
* abort_multipart
* complete_multipart
* presign_multipart_part
* list_multipart_parts
Then, S3Store and S3BackupStore either delegate directly to S3Helper or have their own special methods to call S3Helper for these methods. FileStore.temporary_upload_path has also removed its dependence on upload_path, and can now be used interchangeably between the stores. A similar change was made in the frontend as well, moving the multipart related JS code out of ComposerUppyUpload and into a mixin of its own, so it can also be used by UppyUploadMixin.
Some changes to ExternalUploadManager had to be made here as well. The backup direct uploads do not need an Upload record made for them in the database, so they can be moved to their final S3 resting place when completing the multipart upload.
This changeset is not perfect; it introduces some special cases in UploadController to handle backups that was previously in BackupController, because UploadController is where the multipart routes are located. A subsequent pull request will pull these routes into a module or some other sharing pattern, along with hooks, so the backup controller and the upload controller (and any future controllers that may need them) can include these routes in a nicer way.
PERF: Update like count in visible posts without an extra GET per like
Currently when a user is reading a topic and some post in it receive a
like from another user, the Ember app will be notified via MessageBus
and issue a GET to `/posts/{id}` to get the new like count. This worked
fine for us until today, but it can easily create a self-inflicted DDoS
when a topic with a large number of visitors gets a large number of
likes, since we will issue `visitors * likes` GET requests requests.
This patch optimizes this flow, by sending the new like count down in
the MessageBus notification, removing any need for the extra request.
It shouldn't cause any drift on the count because we send down the full
count instead of the difference too.
Possible follow-ups could include handling like removal.
`d-modal-body.js` was setting the text of a `modal-alert` element to `""`, but not removing any classes on that element. Changing this to call `_clearFlash()` ensures that a variety of styling classes are also removed from the element, which prevents empty alert elements being included on any subsequent modals that are displayed.
Several other controllers have also been modified to change the class of the error from `alert-error` to `error. The `alert-` is unnecessary, as it is added by `_flash(msg)` within `d-modal-body.js`.
We are only using list_multipart_parts right now in the
uploads controller for multipart uploads to check if the
upload exists; thus we don't need up to 1000 parts.
Also adding a note for future explorers that list_multipart_parts
only gets 1000 parts max, and adding params for max parts
and starting parts.
On new macs, `localhost` resolves to IPV6 of `::1` and unfortunately
unicorn doesn't bind to IPv6 by default.
This seems to be the path of least resistance. By using 127.0.0.1 we
force IPv4 which works great.
Support for invites alongside DiscourseConnect was added in 355d51af. This commit fixes the guardian method so that the bulk invite button functionality also works.
* FIX: Preserve field types when updating revision
When a post was edited quickly twice by the same user, the old post
revision was updated with the newest changes. To check if the change
was reverted (i.e. rename topic A to B and then back to A) a comparison
of the initial value and last value is performed. If the check passes
then the intermediary value is dismissed and only the initial value and
the last ones are preserved. Otherwise, the modification is dismissed
because the field returned to its initial value.
This used to work well for most fields, but failed for "tags" because
the field is an array and the values were transformed to strings to
perform the comparison.
* FIX: Reset last_editor_id if revision is reverted
If a post was revised and then the same revision was reverted,
last_editor_id was still set to the ID of the user who last edited the
post. This was a problem because the same person could then edit the
same post again and because it was the same user and same post, the
system attempted to update the last one (that did not exist anymore).
* FIX: small copy fix for embedding.sample
* FIX: improve copy for site_description and short_site_description
As part of the setup wizard, improve the description of these two
strings to add context on where they will be used, so that it is
clearer how to write each one.
