* Remove ResetDefaultEventEngine
Now that it is a weak_ptr, there's no need to explicitly reset it. When
the tracked shared_ptr is deleted, the weak_ptr will fail to lock, and a
new default EventEngine will be created.
* forget existing engine with FactoryReset
* init/shutdown in event engine for now
* fix
* fix
* fix windows deadlock
* Automated change: Fix sanity tests
* fix
* better windows fix

* Reland x2: Make GetDefaultEventEngine return a shared_ptr
* remove thread leak from NativeDNSResolver
This is not going to work for resolvers that support cancellation.
* give resolvers bounded lifetimes
Some resolver own EventEngines. EventEngines cannot run off the end of
the process since they have unjoined threads (problematic in a small set
of environments). This gives resolvers bounded lifetimes, and allows
replacement of resolvers without ASAN issues of deleting resolvers in
active use (occurs in tests).
* fix
* fix windows
* fix surface init test
* fix
* sanitize
* use after move
* the test must wait for the callback to be destroyed
* windows fix: delete the resolver on iomgr shutdown, not before
* Make TimerManager threads non-joinable
On gRPC shutdown, any unjoined TimerManager threads will cause TSAN to
detect thread leaks. This fix resolves issues I saw in end2end test
shutdown in another PR, where a single timer manager thread was always
alive after the test ended.
The long-term solution is to integrate the new ThreadPool here, but this
unblocks me for now.
* backport fix
* fix
* shared_ptr<EventEngine> in EventEngine benchmarks
* [WIP] EventEngine::Run microbenchmarks
* Add fanout impl and fix tracking of time spent doing work in threads
* tune down benchmarks; fix fanout counting logic.
* tune down closure fanout tests
* format
* odr
* reviewer feedback
* unify some fanout logic; add a large-AnyInvocable test
lambdas that take an allocation are about 10x slower
* reviewer feedback
* fix invalid vector access
* rm DNS
* format
* copy params for each lambda callback
This fixes segfaults when we cannot ensure all callbacks are complete
before exiting the test.
* s/promise/Notification/g bm_exec_ctx
* ODR and leak
* fix division by zero

* WorkQueue
* weaken the large obj stress test for Windows; documentation

* add PopBack tests: same performance profile exactly
* use Mutex instead of Spinlock
It's safer, and so far equally performant in benchmarks of opt builds
* add deque test for comparison. It is faster on all tests.
* Add sparsely-populated multi-threaded benchmarks.
* fix
* fix
* refactor to help thread safety analysis
* Specialize WorkQueue for Closure*s and AnyInvocables
* remove unused callback storage
* add single-threaded benchmark for closure vs invocable
* sanitize
* missing include
* move bm_work_queue to microbenchmarks so it isn't exported
* s/workqueue/work_queue/g
* use nullptr instead of optionals for popped closures
* reviewer test suggestion
* private things are private
* add a work_queue fuzzer
Ran for 10 minutes @ 42 jobs @ 42 workers. Zero failures.
Checked in a selection of 100 good seeds after merging the thousands of
results.
* fix
* fix header guards
* nuke the corpora
* feedback
* sanitize
* Timestamp::Now
* fix
* fuzzers do not work on windows
* windows does not like multithreaded benchmark tests
