Adds the parallel_tests gem, and redis/postgres configuration for running rspec tests in parallel. To use:
```
rake parallel:rake[db:create]
rake parallel:rake[db:migrate]
rake parallel:spec
```
This brings the test suite from 12m20s to 3m11s on my macOS machine
- Fixes deprecation regarding usage of BigDecimal in dev
- Handle edge case where query_hash would clear a non existent result
- Minor perf improvement to query_single
Most important thing though is that we are now on the latest gem
The only reason this was done was to remove this deprecation when running
tests.
```
/home/sam/.rbenv/versions/2.6.1/lib/ruby/gems/2.6.0/gems/mini_sql-0.1.10/lib/mini_sql/coders.rb:5: warning: BigDecimal.new is deprecated; use BigDecimal() method instead.
```
Ruby 2.5.3 has an upatched issue that crashes unicorn after fork:
https://bugs.ruby-lang.org/issues/14634
This will be patched in 2.5.4 however for now just warn people dev is slower
and disable async logging on the older rubies
Another group of gems updated, better_errors is fairly safe as its for dev
chunky_png fairly safe, used for getting image info from pngs, erubi update
is very safe. Sanitize is used by onebox and should always be on latest.
Long term we should think of making sanitize an optional dependency on onebox
cause we are happy to just provide methods from core to do this and it would
remove nokogumbo and sanitize deps.
This follows up on 03376224 which reverted the redis update which is not
supported, rest of the gems should be fine.(unicorn / nokogiri / sidekiq /
pg)
This updates a few more lower risk gems, the main goal here is to have
nothing outdated. Avoiding a giant commit is going to make it slightly
easier to partially roll back if something goes wrong
Two very low risk updates, message_bus has been released no need to depend
on pre-release.
mini_racer update is for a very minor change (shared isolates are not used
in discourse so it is not a fix we technically need)
Launching Discourse no longer should require foreman in dev. We can simply
use `bin/unicorn` which automatically launches a sidekiq worker.
The foreman gem depends on thor ~> 0.19.1 which is no longer supported in
rails 6. So this pre-emptively prepares us for it.
