Support IPC endpoint

[axic]

Some tools (i.e. Mist, Solidity tests, etc.) have switched to use IPC instead of the HTTP-RPC.

Would it be hard adding IPC support? (That would need to replace the http server when the option is turned on. Ideally listening on both an IPC file and HTTP would be nice.)

[tcoulter]

Quick google makes it look promising: https://www.npmjs.com/package/node-ipc

I have no idea how IPC works, but this would be a good feature.

[axic]

@tcoulter well the term IPC is overused, but what these clients really mean is a Unix socket or a Windows pipe. node-ipc seems to support that.

[boorac]

Definitely would love to see this happen

[miguelmota]

Looking forward to IPC support

[axic]

I had IPC support implemented in #261, but it was closed after half a year of not merging it :)

@axic just a question on a related problem, but does ganache supports connecting to local node using unix socket?

[davidmurdoch]

@ytrezq it does not. Though I do hope to get this working eventually.

Would love to see this implemented; IPC is much faster than even WSS in an all-local environment (ie, in the case where you have a node in the same machine you're running ganache-core on)

[davidmurdoch]

The newest version of Ganache will utilize uWebsocket.js, which is on par with IPC, performance wise. That said, we are still strongly considering adding IPC support.

It's been 6 years since this issue was opened. Is IPC support still a feature you'd want?

[ytrezq]

For security and efficiency, yes, definitely.

[kryptoklob]

Yes, absolutely @davidmurdoch
