This can cause unbound CPU usage in some cases, and excessive logging in other cases. This commit moves redis readonly information into the local process, but maintains the DistributedCache for postgres readonly state.
followup to #bc03c509
There were 2 problems
1. VALUES was not properly getting multiple results ... we need (1),(2),(3)
not (1,2,3)
2. changes was mistakenly lazy evaluated eg `changed ||=` which meant some
queries were not running
* Remove unused method
* Prefabricate user in category_user_spec.rb
* FIX: Remove notification_level from category_users unique indexes
* FIX: CategoryUser#batch_set wasn't updating pre-existing records
* Improve tests for CategoryUser#batch_set
* FIX: changed was being reported incorrectly
* DEV: Rewrote query to do a bulk insert
* DEV: remove unnecessary parentheses
This is a problem that has long plagued Discourse. The root issue here
is that we have to implement our own link click handler, because
Discourse allows users to create HTML blobs of content with links, and
when those links are clicked they must be handled by the Ember router.
This always involved a certain amount of use of private Ember APIs which
of course evolved over time.
The API has more or less stabilized in the last two years, however we
have hacks in our URLs to handle a dynamic root path, depending on how
forums have set up their filters and in what order.
This patch adds a special case for the root path so we needn't update
the URL ourselves otherwise, which preserves the back button on index
routes. The update call would otherwise insert an extra history event if
a route redirected on transition, breaking the back button.
* DEV: Add a new way to run specs in parallel with better output
This commit:
1. adds a new executable, `bin/interleaved_rspec` which works much like
`rspec`, but runs the tests in parallel.
2. adds a rake task, `rake interleaved:spec` which runs the whole test
suite.
3. makes autospec use this new wrapper by default. You can disable this
by running `PARALLEL_SPEC=0 rake autospec`.
It works much like the `parallel_tests` gem (and relies on it), but
makes each subprocess use a machine-readable formatter and parses this
output in order to provide a better overall summary.
(It's called interleaved, because parallel was taken and naming is
hard).
* Make popen3 invocation safer
* Use FileUtils instead of shelling out
* DRY up reporter
* Moved summary logic into Reporter
* s/interleaved/turbo/g
* Move Reporter into its own file
* Moved run into its own class
* Moved Runner into its own file
* Move JsonRowsFormatter under TurboTests
* Join on threads at the end
* Acted on feedback from eviltrout
