This removes a race condition in reset since pendingPorts can be set to nil in reset() If ticker is hit at wrong time, it would crash the unit test. We ensure in reset to avoid this race condition by cancelling the goroutine using killTicker chan. We also properly clean up eveything, so garbage collector can work as expected. To reproduce existing bug: `while go test -timeout 30s github.com/hashicorp/consul/sdk/freeport -run '^(Test.*)$'; do go clean -testcache; done` Will crash after a few 10s runs on my machine. Error could be seen in unit tests sometimes: [INFO] freeport: resetting the freeport package state panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x1125536] goroutine 25 [running]: container/list.(*List).Len(...) /usr/local/Cellar/go/1.14/libexec/src/container/list/list.go:66 github.com/hashicorp/consul/sdk/freeport.checkFreedPortsOnce() /Users/p.souchay/go/src/github.com/hashicorp/consul/sdk/freeport/freeport.go:157 +0x86 github.com/hashicorp/consul/sdk/freeport.checkFreedPorts() /Users/p.souchay/go/src/github.com/hashicorp/consul/sdk/freeport/freeport.go:147 +0x71 created by github.com/hashicorp/consul/sdk/freeport.initialize /Users/p.souchay/go/src/github.com/hashicorp/consul/sdk/freeport/freeport.go:113 +0x2cf FAIL github.com/hashicorp/consul/sdk/freeport 1.607s |
