This method is a huge footgun in production, since it calls
the Redis KEYS command. From the Redis documentation at
https://redis.io/commands/keys/:
> Warning: consider KEYS as a command that should only be used in
production environments with extreme care. It may ruin performance when
it is executed against large databases. This command is intended for
debugging and special operations, such as changing your keyspace layout.
Don't use KEYS in your regular application code.
Since we were only using `delete_prefixed` in specs (now that we
removed the usage in production in 24ec06ff85)
we can remove this and instead rely on `use_redis_snapshotting` on the
particular tests that need this kind of clearing functionality.
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.
This allows text editors to use correct syntax coloring for the heredoc sections.
Heredoc tag names we use:
languages: SQL, JS, RUBY, LUA, HTML, CSS, SCSS, SH, HBS, XML, YAML/YML, MF, ICS
other: MD, TEXT/TXT, RAW, EMAIL

This commit refactors the direct external upload routes (get presigned
put, complete external, create/abort/complete multipart) into a
helper which is then included in both BackupController and the
UploadController. This is done so UploadController doesn't need
strange backup logic added to it, and so each controller implementing
this helper can do their own validation/error handling nicely.
This is a follow up to e4350bb966
Uppy and Resumable slice up their chunks differently, which causes a difference
in this algorithm. Let's take a 131.6MB file (137951695 bytes) with a 5MB (5242880 bytes)
chunk size. For resumable, there are 26 chunks, and uppy there are 27. This is
controlled by forceChunkSize in resumable which is false by default. The final
chunk size is 6879695 (chunk size + remainder) whereas in uppy it is 1636815 (just remainder).
This means that the current condition of uploaded_file_size + current_chunk_size >= total_size
is hit twice by uppy, because it uses a more correct number of chunks. This
can be solved for both uppy and resumable by checking the _previous_ chunk
number * chunk_size as the uploaded_file_size.
An example of what is happening before that change, using the current
chunk number to calculate uploaded_file_size.
chunk 26: resumable: uploaded_file_size (26 * 5242880) + current_chunk_size (6879695) = 143194575 >= total_size (137951695) ? YES
chunk 26: uppy: uploaded_file_size (26 * 5242880) + current_chunk_size (5242880) = 141557760 >= total_size (137951695) ? YES
chunk 27: uppy: uploaded_file_size (27 * 5242880) + current_chunk_size (1636815) = 143194575 >= total_size (137951695) ? YES
An example of what this looks like after the change, using the previous
chunk number to calculate uploaded_file_size:
chunk 26: resumable: uploaded_file_size (25 * 5242880) + current_chunk_size (6879695) = 137951695 >= total_size (137951695) ? YES
chunk 26: uppy: uploaded_file_size (25 * 5242880) + current_chunk_size (5242880) = 136314880 >= total_size (137951695) ? NO
chunk 27: uppy: uploaded_file_size (26 * 5242880) + current_chunk_size (1636815) = 137951695 >= total_size (137951695) ? YES
Rails 6.1.3.1 deprecates a few API and has some internal changes that break our tests suite, so this commit fixes all the deprecations and errors and now Discourse should be fully compatible with Rails 6.1.3.1. We also have a new release of the rails_failover gem that's compatible with Rails 6.1.3.1.
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
* Introduced fab!, a helper that creates database state for a group
It's almost identical to let_it_be, except:
1. It creates a new object for each test by default,
2. You can disable it using PREFABRICATION=0
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
This updates tests to use latest rails 5 practice
and updates ALL dependencies that could be updated
Performance testing shows that performance has not regressed
if anything it is marginally faster now.
* This exposes the token in the Sidekiq dashboard which can be
viewed by an admin and defeats the purpose of using a token
in the download backup email ink.
