Re: ABCL Threads

Hi Marco, 

I don't have experience specifically with threads on abcl yet, but regarding abcl in general, I took on maintenance of the http://gitlab.common-lisp.net/cl-docker-images/abcl/  container image builds and recently got the abcl/ pipelines running green.  So any feedback on those built docker container images (from Marco or anyone on this list) would be welcomed. 

Also I just joined #abcl on libera.chat myself, I'm not sure your handle on there to know whether you're one of the ~8 apparent members in that channel. Anyway, that is a place where you and I (and anyone else interestedd) could brainstorm any ideas or share any quirks regarding those abcl docker images, maybe before they need to get promoted to Issues or MRs in the project.  

Of course we can also discuss threads in there. I would hope bt2 would have most needs covered - diving into Java internals sounds scary, to me at least. 




Thanks,



Dave Cooper

Thanks



Yep, I gathered that much.  I also saw a note in the documentation saying that you can use JSS to use java.util.concurrent.  Can you point me to some examples for that?


Thanks



Marco

 Hi, if I don’t misunderstand the question, a barrier can be implemented using the Java class java.util.concurrent.CountDownLatch.
 
 (I’m not on irc these days except dropping in for a few minutes every other month..)
 
 Best,
