May 25, 2017 Are there any known remaining deadlock bugs in OPTLINK? | ||||

 | Here's three CI runs of the same commit on Windows: https://ci.appveyor.com/project/CyberShadow/digger/build/1.0.108 https://ci.appveyor.com/project/CyberShadow/digger/build/1.0.109 https://ci.appveyor.com/project/CyberShadow/digger/build/1.0.110 The first two got stuck in a link.exe (OPTLINK) invocation and timed out. - Does OPTLINK use threads or thread synchronization primitives? - Is anyone aware of any threading/deadlock bugs in OPTLINK? - Any known workarounds? Like setting CPU affinity? I've never experienced such hangs while I was still using Windows on my development machine, though I think I did notice some hangs under Wine. Digger makes sure to install OPTLINK 8.00.15 (latest at this time, AFAIK) from http://downloads.dlang.org/other/. | |||

Back in the days when I was using the DigtalMars C++ compiler on almost a daily basis I always setted CPU affinity on HT/multicore machines for optlink.exe to avoid lockups.
I'm not aware whether or not there have been any fixes or changes to optlink.exe over the past 8 years regarding this issue.

The CPU affinity is set in the Optlink executable, as it locks up without it. > I've never experienced such hangs while I was still using Windows on my development machine, though I think I did notice some hangs under Wine. > > Digger makes sure to install OPTLINK 8.00.15 (latest at this time, AFAIK) from http://downloads.dlang.org/other/. 8.00.17 is the latest. | |||

Aah, thanks. It would be nice if it was available as a separate download, or bundled with the latest version of DMC. For now I'll change Digger to extract it from a recent DMD zip file.
