It is useful to know that there is a problem with rebooting the internal server. But, hardly anyone is using the internal server anymore. The internal server used to be necessary for scoping and shared-memory control buses, but these are fully supported in the local server now.

There's basically no technical benefit to using the internal server now -- but it does introduce risk: when the language and server are tied together in the same process, a crash in one of the server's threads will also crash the language. So you get more instability for no concrete benefit: not exactly a wise bargain.

My suggestion for this issue is to postpone it for 3.8. If you use the local server instead, then the language will be isolated from the server. Then, if the server crashes during shutdown, well, it's not ideal but the outcome is the same (server process is gone), and the language will still be up. (Sure, by definition, crashing bugs are severe, but we have other open bugs that are actually bad for usability. This one isn't so bad, practically speaking.)

@ceremona - What do you hope to gain by using the internal server?

On my Linux machine (recent master), I see the same behavior with the internal server -- Server.internal.reboot (if the internal server was already running) causes the language to crash. However, Server.internal.quit does not crash.

With the local server, I can reboot as many times as I like and the language remains stable. Moreover, it seems the scsynth process is not crashing either: I get RESULT = 0 in the post window. If it crashed, it would be a non-zero exit code.

I was using the internal server because in the 3.6.6 is was the only way I could use the freqscope in osx :)

we could also get rid of the real internal server and redirect calls to Server.internal to localhost,
with an inform that says something like, "... no benefit to using internal server on 3.7 or higher,
just use localhost instead."
then the accidental crashes are gone, and people would learn about it.

The only reason to have internal server is that you (apparently) have fewer context switches, which may be more efficient. But I don't know if that is still rue after all these years. It would be good to know. If there is little benefit, it might be really better to completely get rid of the internal server (for 3.8) and thus simplify the code base a little.

So yes, the message is a good way for now.

That sounded fishy to me, but actually it's true: "Switching between threads of a single process can be faster than between two separate processes, because threads share the same virtual memory maps, so a TLB flush is not necessary.[3]" -- https://en.wikipedia.org/wiki/Context_switch#Performance

I would not get rid of internal server.

Latency is a bit lower. Also usefull for using scsynth as a module in another program (for example a VST/AU plugin using scsynth as a module only would need to redefine audio interface)

It does not disturb the rest of code

Of course despite keeping the code from internal server the IDE could use only localhost if you prefer.

I agree we should keep it. So the task is to sort out and test the different cases, where which view is supposed to be used. We have:

  • ScopeOut
  • ScopeOut2
  • ScopeView
  • SCScope

It is a bit of a mess.

Of course, also the current issue needs to be fixed, if we can. Otherwise, we publish 3.7 without internal server and do this in 3.8.

Seems to work here now. Feel free to reopen, if the problem persists for you.
