#891: hsc2hs tries to remove an open file ---+ Reporter: eivuokko | Owner: Type: bug | Status: new Priority: normal| Milestone: Component: Compiler |Version: 6.4.2 Severity: normal| Resolution: Keywords:| Os: Windows Difficulty: Unknown | Architecture: Unknown ---+ Comment (by simonpj): Brian Smith adds: hsc2hs generates an EXE file, then executes it, then waits for that process to finish, and then attempts to delete the file. The file is never opened by hsc2hs directly so the GC does not seem to be the cause. It seems that even though waitForProcess returns successfully, Windows still an open file handle for the EXE file when removeFile is called. That is really surprising because I expect that the file should be free to delete after waitForProcess has returned. I tried to rewrite the code so that it enters a remove-catch permission denied-sleep loop but I could not find a portable sleep IO action. For now, I just commented out the entire removeFile action. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/891 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Old description:
hsc2hs sometimes fails with error Permission denied in Windows. This
is because it tries to remove a file it has open handle to. The error
usually repeats per-machine and file, but what file and machine it shows
up with, is random.
As a workaround, calls to removeFile can be removed, or exceptions
catched.

Comment (by duncan):
Would it be possible to distinguish based on the syntax?
{{{
content - getContents
}}}
would not print anything, but
{{{
getContents
}}}
would print. That seems reasonably intuitive to me.

Comment (by ross):
I presume that this is {{{setup haddock}}}, rather than using the GHC
makefiles.
In xhtml, the package description doesn't conform to Haddock syntax.
(This requirement is not mentioned in the Cabal documentation). I can't
fix this, as the directories are not writable by group darcs.
For haskell-src, !QuickCheck, time and X11, a CPP extension needed
recording (now done).
For network, OpenGL, OpenAL, ALUT (and GLUT?) the problem seems to be that
cpphs isn't being passed the -DCALLCONV option set in the buildinfo file.
