* When viewing a tag, the search widget will now show a checkbox to scope the search by tag, which will limit search results to that tag on desktop and mobile
This fix ensures that searches that contain a null byte return a 400
error instead of causing a 500 error.
For some reason from rspec we will reach the raise statement inside
of the `rescue_from ArgumentError` block, but outside of rspec it will
not execute the raise statement and so a 500 is thrown instead of
reaching the `rescue_from Discourse::InvalidParameters` block inside of
the application controller.
This fix raises Discourse::InvalidParameters directly from the search
controller instead of relying on `PG::Connection.escape_string` to
raise the `ArgumentError`.
The global setting disable_search_queue_threshold
(DISCOURSE_DISABLE_SEARCH_QUEUE_THRESHOLD) which default to 1 second was
added.
This protection ensures that when the application is unable to keep up with
requests it will simply turn off search till it is not backed up.
To disable this protection set this to 0.
* 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
Many security scanners like to inject NULL in inputs causing application
to exception out and return a 500
We now handle this exception and render a 400 status back
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.
