Still pondering on this.
Apparently, can't use a shared-access mutex within event handling
callbacks. It deadlocks. Which might be normal if my unbderstand is correct
in that the Wrapped funcs are almost always called in the same goroutine
(the exception being due to promise callbacks).

Ok, thank you!
Does that mean that writing plugins, e.g. for SQLite, can cause issues when
multiple Go extensions are loaded in the same process?
Or is this use-case actually safe, and issues can start to happen only when
there's a Go host and a Go c-shared library in the same process?

Greetings!
I recently stumbled onto a project that implements an SQLite extension in
Go as a c-shared library, and wondered if Go shares its runtime between
multiple c-shared Go libraries in the same process.
I tried searching for issues on Github and through this group, but I wasn't

Updating existing keys in parallel is not guaranteed to be safe. If you
want to modify values, you'd have to do the trick mentioned above where
instead of a map[K]T you use a map[K]*T and to do modification you do *m[k]
= T{...} or whatever.
Go maps do incremental growth work on every update, s
Hi Marc, thanks for your comment:

every mistake, right?
Not at all. I think the idea is to try to catch at compile-time common
mistakes, that are easily made, can be missed during testing and can have
serious consequence
When you use
cmd, err := exec.Command(...)
you then set-up it's environment before execution by setting cmd.Env:
cmd.Env = append(os.Environ(), `PATH="..."`)
and only then run the command:
out, err := cmd.Output()
if err ... { ... }
fmt.Println("output:", out)
The above mostly from
Thank you so much, I am able to add java path. I also need to add some
