* get conclude signal working properly; don't allocate a vector
* wip: add test suite / example / explanation for using utility subsystem
Unfortunately, the test fails right now for reasons which seem
very odd. Just have to keep poking at it.
* explicitly import everything
* fix subsystem-util test
The root problem here was two-fold:
- there was a circular dependency from subsystem -> test-helpers/subsystem ->
subsystem
- cfg(test) doesn't propagate between crates
The solution: move the subsystem test helpers into a sub-module
within subsystem. Publicly export them from the previous location
so no other code breaks.
Doing this has an additional benefit: it ensures that no production
code can ever accidentally use the subsystem helpers, as they are compile-
gated on cfg(test).
* fully commit to moving test helpers into a subsystem module
* add some more tests
* get rid of log tests in favor of real error forwarding
It's not obvious whether we'll ever really want to chase down
these errors outside a testing context, but having the capability
won't hurt.
* fix issue which caused test to hang on osx
* only require that job errors are PartialEq when testing
also fix polkadot-node-core-backing tests
* get rid of any notion of partialeq
* rethink testing
Combine tests of starting and stopping job: leaving a test executor
with a job running was pretty clearly the cause of the sometimes-hang.
Also, add a timeout so tests _can't_ hang anymore; they just fail
after a while.
* rename fwd_errors -> forward_errors
* warn on error propagation failure
* fix unused import leftover from merge
* derive eq for subsystemerror
