During system tests, we don't want the headless browser to load
external resources:
- It is faster (we don't wait for external resources to be loaded)
- It avoids leaking our test setup to external service
Fixes#6982
Move everything to initializers, and replace the email settings
interceptor by a BalancerDeliveryMethod.
It has the advantage that it can be configured entirely from the
`config/environment.rb` file, without an extra file to look at.
Before, every time a password was tested, the dictionaries were parsed
again by zxcvbn.
Parsing dictionaries is slow: it may take up to ~1s. This doesn't matter
that much in production, but it makes tests very slow (because we tend
to create a lot of User records).
With this changes, the initializer tester is shared between calls, class
instances and threads. It is lazily loaded on first use, in order not to
slow down the application boot sequence.
This uses ~20 Mo of memory (only once for all threads), but makes tests
more that twice faster.
For instance, model tests go from **8m 21s** to **3m 26s**.
NB:
An additionnal optimization could be to preload the tester on
boot, before workers are forked, to take advantage of Puma copy-on-write
mechanism. In this way all forked workers would use the same cached
instance.
But:
- We're not actually sure this would work properly. What if Ruby updates
an interval ivar on the class, and this forces the OS to copy the
whole data structure in each fork?
- Puma phased restarts are not compatible with copy-on-write anyway.
So we're avoiding this optimisation for now, and take the extra 20 Mo
per worker.
These constants were defined so that existing enqueued jobs wouldn't
fail during the app upgrade.
These jobs are long gone. Let's remove the compatibility code.
Previously Sentry reported job exceptions even if a retry
strategy was specified. So we had to ignore retried job exceptions
entirely.
Since sentry-delayed-job 0.4.4, we can instead let Sentry report
job exceptions when the retry count is exhausted. Which is
exactly the behavior we want.
