* Extend the integration test harness to track FDs
Motivation
This patch extends the NIO integration test harness to track
file descriptors, in particular to search for leaks. This
change has been validated on Linux and Darwin, and in both cases
correctly diagnoses FD leaks.
The goal is to enable us to regression test for things like
Modifications
- Add support for hooking socket and close calls.
- Wire up this support into the test harness.
- Extend the test harness to handle the logging.
- Add new regression test for #2047.
Results
We can write regression tests for FD leaks.
* Disable FD checking in most builds.
I'm doing this for speed reasons
* Always print the leaked fds number
Motivation:
The Swift runtime is now using malloc_zone_*, we need to implement
replacements for these too. This is just a first pass, eventually, we
should implement _all_ replacements as `malloc_zone_memalign` which is
powerful enough to implement all others.
Modifications:
Provide new replacements.
Result:
Alloc tests work again on macOS.
