* upgrade to rand 0.7.0 (MSRV 1.32)
* upgrade to parking_lot 0.9.0
* Remove last non-dev dependency on rand crate (#1324)
Use std RandomState for XorShift seeding. This allows dropping _rand_
crate dep here, accept as a dev dependency for tests or benchmarks.
* increase CI MSRV to 1.31.0
* increase nightly for CI TSAN tests
* add TSAN suppressions for recent rand related updates
* make latest TSAN suppression patterns more general
* upgrade tempfile dev dep for common rand version
But avoid tempfile 3.2 for now, since history demonstrates it bumps
rand versions and MSRV in MINOR updates.
* update (dev dep) env_logger to latest 0.6
* reactor, threadpool: bump PATCH versions, doc links, change logs [ci-release]
This also bumps a number of sub crates:
* tokio-executor (0.1.3)
* tokio-io (0.1.8)
* tokio-reactor (0.1.4)
* tokio-threadpool (0.1.6)
* tokio-timer (0.2.6)
* tokio-udp (0.1.2)
* Allow customizing the threadpool's parker
This patch allows the user of threadpool to customize how the worker
threads park themselves. This allows custom parking logic to be
injected. For example, this allows embedding a timer on each worker
thread.
* Call `park` instance every so often.
Since the `park` is now customizable, it might have logic that must be
called every so often. For example, a timer might have timeouts that it
must expire.
Currently, if a worker is very busy, it won't call into the `park`
instance. This patch changes this so that after every 32 task
invocations, `park` is called with a duration of zero.
