modd fails to kill process when run by `go run`

[llimllib]

With this modd.conf:

**/*.go {
    daemon +sigint: PGDATABASE=soapbox_dev PGSSLMODE=disable soapboxd
}

modd works perfectly.

With this one:

**/*.go {
    daemon +sigint: PGDATABASE=soapbox_dev PGSSLMODE=disable go run cmd/soapboxd/main.go
}

modd tried to kill the process but fails on mac os x. It hangs at:

15:57:58: daemon: PGDATABASE=soapbox_dev PGSSLMODE=disable go run cmd/soapboxd/main.go
>> starting...
2017/08/07 15:58:00 soapboxd listening on 0.0.0.0:9090
>> sending signal interrupt

I'm guessing that this has something to do with the parent process being go, rather than the daemon itself? Or something like that?

Soapboxd is a very basic grpc server, and I'm on go 1.8

@llimllib did you find a resolution to this? Would love to know!!

[llimllib]

@cathykc I didn't, unfortunately!

Ah sad :( let me know if you landed on another auto restart solution for go apps

This is the only thing I was wanting to do

Using a prep statement to build then running the executable worked for me.

dir/**/*.html {
    prep: go build
    daemon +sigterm: ./app
}

This has been fixed in master. Processes are now spawned with a process group, and signals are sent to the entire process group. The root of the issue here was that go run was not passing signals to child processes.

Please re-open if you're still seeing problems on master. Version 0.7 should be out soon.

Great, thanks!
