The Pivotal copyright notice needs to be retained. That's the right
thing to do and the MIT license requires it. However, using it by itself
becomes more obviously incorrect with each passing year since Pivotal
ceased to exist. Moreover, Pivotal hasn't actually been the sole
copyright owner since the first external contribution was merged.
Contributors were not asked to sign a copyright assignment, so they
retain copyright to their contributions.
"Copyright (c) 2008-2019 Pivotal Labs" complies with the terms of the
license and acknowledges Pivotal's outsized role in developing Jasmine.
"Copyright (c) 2008-$YEAR The Jasmine developers" acknowledges all
authors and will remain correct in the future.
This is intended to support parallel execution, which is planned for a
future release of Jasmine. Because the execution of unrelated suites will
interleave when run in parallel, reporters will not be able to assume
that the most recent `suiteStarted` event identifies the parent of the
current suite/spec. By adding this feature now, we allow reporters to
support both parallel execution and at least some 4.x versions without
having to implement two different ways of finding the parent suite.
* Avoid setTimeout in Node, because we don't need the overhead there.
* Still call setTimeout in browsers to prevent the tab from being killed.
* Use queueMicrotask in Safari, because it's dramatically faster than
MessageChannel there.
* Continue to use MessageChannel in other supported browsers becuase it's
somewhat faster than queueMicrotask there.
* Don't use setImmediate any more because there's a faster alternative in
all supported envs.
In jasmine-core's own test suite, this yields a roughly 50-70% speedup
in Node, ~20% in Edge, and 75-90%(!) in Safari.
Previously, an error that occurred after Jasmine started to report the
suiteDone or specDone event for the current runable would not be reliably
reported. Now such an error is reported on the nearest ancestor suite whose
suiteDone event has not yet been reported.
