When rebaking and in various other places for posts, we
run through the uploads and call `update_secure_status` on
each of them.
However, if the secure status didn't change, we were still
calling S3 to change the ACL, which would have been a noop
in many cases and takes ~1 second per call, slowing things
down a lot.
Also, we didn't account for the s3_acls_enabled site setting
being false here, and in the specs doing an assertion
that `Discourse.store.update_ACL` is not called doesn't
work; `Discourse.store` isn't a singleton, it re-initializes
`FileStore::S3Store.new` every single time.
This adds a new secure_uploads_pm_only site setting. When secure_uploads
is true with this setting, only uploads created in PMs will be marked
secure; no uploads in secure categories will be marked as secure, and
the login_required site setting has no bearing on upload security
either.
This is meant to be a stopgap solution to prevent secure uploads
in a single place (private messages) for sensitive admin data exports.
Ideally we would want a more comprehensive way of saying that certain
upload types get secured which is a hybrid/mixed mode secure uploads,
but for now this will do the trick.
This test flakes occassionally, possibly because
of the arg ordering which we do not guarantee.
In future if this keeps occurring we may want to
try make expect_enqueued_with not care about argument
orders or the order of arrays etc within those arguments.
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
This table holds associations between uploads and other models. This can be used to prevent removing uploads that are still in use.

Incorporates learnings from /t/64227:
* Changes the code to set access control posts in the rake
task to be an efficient UPDATE SQL query.
The original version was timing out with 312017 post uploads,
the new query took ~3s to run.
* Changes the code to mark uploads as secure/not secure in
the rake task to be an efficient UPDATE SQL query rather than
using UploadSecurity. This took a very long time previously,
and now takes only a few seconds.
* Spread out ACL syncing for uploads into jobs with batches of
100 uploads at a time, so they can be parallelized instead
of having to wait ~1.25 seconds for each ACL to be changed
in S3 serially.
One issue that still remains is post rebaking. Doing this serially
is painfully slow. We have a way to do this in sidekiq via PeriodicalUpdates
but this is limited by max_old_rebakes_per_15_minutes. It would
be better to fan this rebaking out into jobs like we did for the
ACL sync, but that should be done in another PR.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
Transient errors in migration are ignored, silently corrupting
data, and the migration is incomplete and misses many sources of
uploads, which will lead to an incorrect expectation of independence
from the remote object storage after announcing that the migration
was successful, regardles of whether transient errors permanently
corrupted the data.
Remove this migration until such time as it is re-written to
follow the same pattern has the migration to s3, moving the
core logic out of the task.
Extracted commonly used spec helpers into spec/support/uploads_helpers.rb, removed unused stubs and let definitions. Makes it easier to write new S3-related specs without copy and pasting setup steps from other specs.
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.")
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.
* 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.
