Hi,
today, naddy@ ran into this error (for devel/shellcheck, but this doesn't
matter here):
/usr/local/bin/ghc-pkg recache '--package-db=dist/package.conf.inplace'
===> Exiting devel/shellcheck,-lib with an error
ghc-pkg: /usr/local/lib/ghc/package.conf.d/network-2.6.2.1.conf:
openBinaryFile: does not exist (No such file or directory)
I'm quite sure that this happened while dpb(1) was junking, removing
unused packages, including hs-network, and that it's a double bug
in ghc-pkg (it shouldn't look at the system-wide package db when
run with --package-db=dist/package.conf.inplace, and it should do
some kind of locking in case another ghc-pkg is running at the same
time).
So if you're doing bulk builds with dpb(1) and have a ports failing
with an error message from ghc-pkg similar to the above one, please
consider restarting the build of the failed port (by removing the
corresponding dpb lock file) for now, unless it really starts to
happen often.
I hope to get my hands dirty with ghc-8.8 or 8.10, which may or may
not behave better.
Ciao,
Kili
