This reverts commit 8b46f14744.
It corrects the reason for the revert:
We rely on SafeMigrate existing cause we call it from migrations,
Zeitwerk will autoload it.
Instead of previous pattern we explicitly bypass all the hacks in
production mode.
We need to disable SafeMigrate cause it is not thread safe.
A thread safe implementation is possible but not worth the effort,
we catch the issues in dev and test.
Previously we were migrating multisites serially, this is extremely slow
especially when 200 dbs are involved.
The new implementation defaults to running 20 migrations concurrently, leading
to a 20x speedup.
We also amended it so errors are printed out last, something that makes
debugging failures easier.
This is code specific to Discourse cause we integrate SeedFu with our
migrations and can not include this in the multisite gem.
If a migration performs no changes it should not output stuff.
Previously we would output information about seeds which was very noisy.
On multisite this was particularly bad
Get rid of harmful each loop over uploads to update. Instead we put all the unique access control posts for the uploads into a map for fast access (vs using the slow .find through array) and look up the post when it is needed when looping through the uploads in batches.
On a Discourse instance with ~93k uploads, a simplified version of the old method takes > 1 minute, and a simplified version of the new method takes ~18s and uses a lot less memory.
If the “secure media” site setting is enabled then ALL files uploaded to Discourse (images, video, audio, pdf, txt, zip etc. etc.) will follow the secure media rules. The “prevent anons from downloading files” setting will no longer have any bearing on upload security. Basically, the feature will more appropriately be called “secure uploads” instead of “secure media”.
This is being done because there are communities out there that would like all attachments and media to be secure based on category rules but still allow anonymous users to download attachments in public places, which is not possible in the current arrangement.
This is mostly useful while developing a plugin, to avoid manual actions of deleting tables and schema_migrations rows.
Usage:
bundle exec rake plugin:migrate:down[discourse-calendar]
* Improve the bookmark mobile on modal so it doesn't go all the way to the edge and the custom datetime input is easier to use
* Improve the rake task for syncing so it does not error for topics that no longer exist and batches 2000 inserts at a time, clearing the array each time
* Add uploads:sync_s3_acls rake task to ensure the ACLs in S3 are the correct (public-read or private) setting based on upload security
* Improved uploads:disable_secure_media to be more efficient and provide better messages to the user.
* Rename uploads:ensure_correct_acl task to uploads:secure_upload_analyse_and_update as it does more than check the ACL
* Many improvements to uploads:secure_upload_analyse_and_update
* Make sure that upload.access_control_post is unscoped so deleted posts are still fetched, because they still affect the security of the upload.
* Add escape hatch for capture_stdout in the form of RAILS_ENABLE_TEST_STDOUT. If provided the capture_stdout code will be ignored, so you can see the output if you need.
The rake task was broken, because the addition of the
UploadSecurity check returned true/false instead of the
upload ID to determine which uploads to set secure.
Also it was rebaking the posts in the wrong place and
pretty inefficiently at that. Also it was rebaking before
the upload was being changed to secure in the DB.
This also updates the task to set the access_control_post_id
for all uploads. the first post the upload is linked to is used
for the access control. if the upload doesn't get changed to
secure this doesn't affect anything.
Added a spec for the rake task to cover common cases.
### UI Changes
If `SiteSetting.enable_bookmarks_with_reminders` is enabled:
* Clicking "Bookmark" on a topic will create a new Bookmark record instead of a post + user action
* Clicking "Clear Bookmarks" on a topic will delete all the new Bookmark records on a topic
* The topic bookmark buttons control the post bookmark flags correctly and vice-versa
Disabled selecting the "reminder type" for bookmarks in the UI because the backend functionality is not done yet (of sending users notifications etc.)
### Other Changes
* Added delete bookmark route (but no UI yet)
* Added a rake task to sync the old PostAction bookmarks to the new Bookmark table, which can be run as many times as we want for a site (it will not create duplicates).
### General Changes and Duplication
* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file.
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.
### Viewing Secure Media
* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`
### Removed
We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.
* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.
The QUnit rake task starts a server in test mode. We need a tweak to allow dynamic CSP hostnames in test mode. This tweak is already present in development mode.
To allow CSP to work, the browser host/port must match what the server sees. Therefore we need to disable the enforce_hostname middleware in test mode. To keep rspec and production as similar as possible, we skip enforce_hostname using an environment variable.
Also move the qunit rake task to use unicorn, for consistency with development and production.
* Add a rake task to disable secure media. This sets all uploads to `secure: false`, changes the upload ACL to public, and rebakes all the posts using the uploads to make sure they point to the correct URLs. This is in a transaction for each upload with the upload being updated the last step, so if the task fails it can be resumed.
* Also allow viewing media via the secure url if secure media is disabled, redirecting to the normal CDN url, because otherwise media links will be broken while we go and rebake all the posts + update ACLs
This used to work due to side effects.
`rake parallel:migrate` used to work very inconsistently and would only migrate
some of the databases.
This introduces the recommended change to db.yml so the correct database is
found based off TEST_ENV_NUMBER if for some reason we did not set it using
RAILS_DB
Also avoids a bunch of schema dumping which is not needed when migrating
parallel specs
DB number 1 is very odd cause for whatever reason parallel spec is not
setting it.
API keys are now only visible when first created. After that, only the first four characters are stored in the database for identification, along with an sha256 hash of the full key. This makes key usage easier to audit, and ensures attackers would not have access to the live site in the event of a database leak.
This makes the merge lower risk, because we have some time to revert if needed. Once the change is confirmed to be working, we will add a second commit to drop the `key` column.
This is required because bin/rake automatically loads plugins when migrating. In our continuous integration, we don't want plugins to break the core build. They should only be loaded for the plugin build.
* FEATURE: Normalize the service worker route
Update cache headers so they are not immutable outside of the rails app
Add the ability to purge the service worker cache from localhost
Rails -> nginx will pass immutable flags so the file is cached until reloaded.
In most cases, nginx will have its cache flushed on rebuild (new image)
For those needing dynamic re-caching (such as upgrading via the UI),
a rake task for flushing the service worker script is provided
through `assets:flush_sw`
This PR introduces a new secure media setting. When enabled, it prevent unathorized access to media uploads (files of type image, video and audio). When the `login_required` setting is enabled, then all media uploads will be protected from unauthorized (anonymous) access. When `login_required`is disabled, only media in private messages will be protected from unauthorized access.
A few notes:
- the `prevent_anons_from_downloading_files` setting no longer applies to audio and video uploads
- the `secure_media` setting can only be enabled if S3 uploads are already enabled and configured
- upload records have a new column, `secure`, which is a boolean `true/false` of the upload's secure status
- when creating a public post with an upload that has already been uploaded and is marked as secure, the post creator will raise an error
- when enabling or disabling the setting on a site with existing uploads, the rake task `uploads:ensure_correct_acl` should be used to update all uploads' secure status and their ACL on S3
For this to work we need to overwrite `db:rollback` in our Rakefile like
we do for migrate, so that it removes the load_config dependency. This
allows our custom migration paths to work.
