roastario · web-flow · commit 88894bc5923f · 2019-07-02T18:38:33.000Z
* add a shared memory port allocator to allow multiple processes to share a single allocation pool

* remove dangerous reset function on port allocator

* set forkCount = 2 in node integration test

* only allow one build of a cordapp at any given time for Driver tests

* make all portallocation requests use same starting point

* globally set forks to 6

* tweak forking parameters to allow parallel builds

* tweak unit test parallelism

* 2 workers for integrationTest

* some more tweaks for parallel builds

* some more tweaks for parallel builds

* seems that 49K is not the start of ephemeral ports on all kernels

* tweak parallel settings

* try fix RPC shutdown test in parallel env

* add some logging for RPC shutdown test

* added some logging around PortAllocation tests - try figure out where they are getting stuck

* added some logging around PortAllocation tests - try figure out where they are getting stuck

* fix api-scanner tests

* minimize api changes

* revert to complying with existing API

* add the AtomicInteger for api compatibility reasons

* make sizing script executable

* address review comments pt1

* address review comments pt2

* fix compile errors after review comments

* return to using home dir as temp dir seemed to interact badly with gradle
