#8591: Concurrent executions of ghc-pkg can cause inconstant package.cache files -------------------------------------+------------------------------------- Reporter: janm | Owner: pgj Type: bug | Status: new Priority: normal | Milestone: Component: Package | Version: 7.6.3 system | Keywords: ghc-pkg race Resolution: | Architecture: Unknown/Multiple Operating System: FreeBSD | Difficulty: Unknown Type of failure: Other | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by pgj): Replying to [comment:5 janm]:
I am running a test build now but code inspection shows that the same race is present. I expect it to fail.
All right, excellent, thanks.
I also see that the FreeBSD port for lang/ghc limits concurrency to 4 jobs, added in SVN rev 348842. Assuming you're also pgj@freebsd you committed the change, so probably know! This was in response to FreeBSD bug ports/186829.
Well, to be honest, I did not realize that it was a related issue. In the past, the GHC build system already had problems with parallel builds on FreeBSD due to e.g. low-resolution timestamps in the file system. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8591#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
