Re: [GHC] #647: Socket bug on Mac OS X, with patch

#647: Socket bug on Mac OS X, with patch ----------------------------------+----------------------------------------- Reporter: gwright@xxxxxxxxxxx | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/network | Version: 6.4.1 Severity: normal | Resolution: Keywords: "OS X" Sockets | Os: MacOS X Difficulty: Easy (1 hr) | Architecture: powerpc ----------------------------------+----------------------------------------- Comment (by vs@xxxxxxxxx): Looking at sockaddr, sa_len looks like to be the culprit since it isn't initialized and thus a likely candidate to contain bogus values. The other members of the structure should all get initialized explicitly. Could you try initializing this field with the proper length? Other applications explicitly test the presence of sa_len, but I doubt that GHC runs no OSes that do not have this member anyway.

[GHC] #659: Code bloat for instances of empty classes

Comments refer to CCallable and CReturnable, so I think this is just a leftover; removing it didn't cause any crashes for me, but a Wizard who knows the code should have a short glance at it first. {{{ Index: ghc/compiler/typecheck/TcInstDcls.lhs =================================================================== RCS file: /home/cvs/root/fptools/ghc/compiler/typecheck/TcInstDcls.lhs,v retrieving revision 1.182 diff -u -r1.182 TcInstDcls.lhs --- ghc/compiler/typecheck/TcInstDcls.lhs 6 Jan 2006 16:30:19 -0000 1.182 +++ ghc/compiler/typecheck/TcInstDcls.lhs 17 Jan 2006 02:18:19 -0000 @@ -395,18 +395,6 @@ -- See Note [Inline dfuns] below dict_rhs - | null scs_and_meths - = -- Blatant special case for CCallable, CReturnable - -- If the dictionary is empty then we should never - -- select anything from it, so we make its RHS just - -- emit an error message.

Re: ghci module list

Frederik Eaton wrote: Ghci still seems to be erasing the "list of current imported modules" (I'm sorry I don't know what to call it) whenever I load a file; sometimes this even means removing the module corresponding to the just-loaded file from that list... *Fu.Vector> :load "Boost.hs" ... Ok, modules loaded: Fu.Vector, Fu.Prepose, Boost. *Fu.Vector> :m + Boost *Fu.Vector Boost> :load "Boost.hs" ... Ok, modules loaded: Fu.Vector, Fu.Prepose, Boost. *Fu.Vector> -- after the load command, Boost is missing On an aside, I was wondering about the feasibility of having some sort of feature resembling Octave's (and probably Matlab's) "function files" implementation, in which modified files are automatically reloaded by the interpreter. I guess a timestamp check could happen for each loaded module before ghci executes each new piece of command-line input. I wonder how useful people think this would be. $ ghci --version The Glorious Glasgow Haskell Compilation System, version 6.5.20051208 Since you're using HEAD, perhaps you could try this again? I believe the behaviuor should be better now. Cheers, Simon
