Re: How do threads work in command-line REPL?

I just tried with boot real: > boot.user=> (.getId (Thread/currentThread)) > 34 > boot.user=> (.getId (Thread/currentThread)) > 34 > boot.user=> (.getId (Thread/currentThread)) > 34 > boot.user=> (.getId (Thread/currentThread)) > 34 > boot.user=> (.getId (Thread/currentThread)) > 34 > boot.user=>

Re: How do threads work in command-line REPL?

That seems pretty weird. I can't reproduce it. I'm using lein 2.5.2. On Tuesday, February 9, 2016 at 12:19:09 PM UTC-6, Nathan Marz wrote: > > I was doing some work that involved the use of thread locals, and I > noticed that within a REPL session (launched via 'lein repl') my thread > locals

Re: How do threads work in command-line REPL?

yep..now I get the same weird result with boot too: boot.user=> (.getId (Thread/currentThread)) 34 boot.user=> (.getId (Thread/currentThread)) 34 boot.user=> (.getId (Thread/currentThread)) 34 boot.user=> (.getId (Thread/currentThread)) 34 boot.user=> (.getId (Thread/currentThread)) 34

Re: How do threads work in command-line REPL?

I should clarify that the thread id doesn't change instantly, it seems to change when I've left it idle for a bit. Also on lein 2.5.2. On Tue, Feb 9, 2016 at 1:45 PM, Mimmo Cosenza wrote: > I just tried with boot real: > > boot.user=> (.getId (Thread/currentThread)) >

Re: How do threads work in command-line REPL?

These would be consistent with having a background thread pool where the ttl expired that were running your repl commands. I was able to repro in lein after waiting a bit. The default clojure.main/repl doesn't do anything like that, but maybe lein and boot do (perhaps via nrepl or something?)

How do threads work in command-line REPL?

I was doing some work that involved the use of thread locals, and I noticed that within a REPL session (launched via 'lein repl') my thread locals would reset themselves to their initial value. I did some digging and found that the thread id keeps changing within a single REPL session, e.g.:

Re: How do threads work in command-line REPL?

I'm pretty fuzzy on how nREPL works, so I might be getting it wrong here ... but I think it processes each method through a `future`. See: https://github.com/clojure/tools.nrepl/blob/master/src/main/clojure/clojure/tools/nrepl/server.clj#L28 All of the nREPL operations are async, AFAIK, and I

Re: How do threads work in command-line REPL?

Yea, that code seems to explain the behavior we're seeing. I opened an issue for this: http://dev.clojure.org/jira/browse/NREPL-80 On Tue, Feb 9, 2016 at 7:38 PM, Jony Hudson wrote: > Ahem. > > "method" -> "message" > > > Jony > > > On Wednesday, 10 February 2016 00:35:16
