The Network fix wasn't merged in (just too late). Ok, I'll take a look at the diffs and summarise the fixes... here goes: - Literal strings could be duplicated sometimes - fixes for deriving Eq/Enum on large datatypes in GHCi - -no-hs-main has a sensible meaning in --make mode now (it forces linking even if there's no Main) - Fix for avoiding recompilation when there are stub files around (didn't pick up the stubs properly before) - Fixes for FFI decls containing type variables - MacOS X fixes for GHCi - Filenames with spaces don't cause problems in GHCi now - GHCi doesn't get confused if your code installs a signal handler for ^C - -pgmL now works as advertised - specifying filenames without the trailing .hs/.lhs works again in --make and GHCi. - Fix for "class ops that do not introduce foralls" (a cause of crashes with certain kinds of class methods). - Fix a crash when a class op is used as a record selector - Fix for deriving on records with fields with names with leading underscores. - Fixes for passing/returning FunPtr in the FFI - hsc2hs works in a binary distribution - Fixes for crashes in the biographical and retainer profilers. - Some signals were inadvertently blocked by the RTS - Uninitialised variable in the storage manager causes crashes - Fix for hp2ps -c - hsc2hs should now work on Windows - Fix off-by-one in Data.PackedString.splitWithPS - uninitialised elements in UArrays are now filled with zero. - Integer divide by zero is now consistently a catchable exception (previously it could just result in SIGFPE). - Fix for terminal buffering on Solaris - System.Console.GetOpt fixes - Fix for converting Integer to Int64/Word64 - Network.accept doesn't fail if the host fails to reverse-lookup. Cheers, Simon

This would at least partly solve the problem. Yes, I think this would be a better solution - at least more consistent with the way configure handles other such things. The right thing to do is to add --with-readline-includes=... --with-readline-libraries=... and --with-gmp-includes=... --with-gmp-libraries=... Incidentally, why are the -Wl,-R<dir> options needed? I've never come across that before, usually the runtime linker just finds the libraries in the place they were originally linked from. > I will also update the NetBSD package (port) with these patches.

Note that HC files can also be platform dependent, since they depend in some cases on the values of symbols from config.h. We used to try to keep .hc files completely platform-independent, but I've come around to the conclusion that this isn't a realistic goal. As soon as you use a platform-dependent #ifdef or #define in the Haskell source (and we do that a fair bit in the libraries and even the compiler), the property is lost. So, while one set of .hc files might work for all the versions of NetBSD you want to build the compiler on, we don't guarantee it. Cheers, Simon

ptrace for profiling?
by John Meacham 31 Mar '03

31 Mar '03

this may be a totally absurd request, but would it be possible to use ptrace or some other mechanism for poking a running program to cause a program to start generating profiling data or change what type of profiling data it is producing? I tend to view the profiling graph in real-time as I run my Haskell program interactively. every now and again I notice my program is behaving oddly but I am unable to reproduce the events that led to the odd behavior. It would be nice to be able to poke the program in such a way to cause it to start writing profiling frames to the stack for a bit. is this plausible?

Patches for NetBSD port and automatic .hc bootstrap (long)
by Urban Boquist 30 Mar '03

30 Mar '03

Hi GHC maintainers, below find a set of patches that hopefully should fix the following for ghc-5.04.3: 1. (re-)port to NetBSD/i386. - the last GHC to work for NetBSD was 4.04, I think. Since then, both GHC and NetBSD has changed a lot... 2. restore the ability to do an automatic bootstrap from .hc files. - at least the updated distrib/hc-build script runs to completion without errors for me now on NetBSD/i386, and the resulting compiler seems to work fine (at least it is able to compile itself once again). All this on a system with no previous GHC installed. I think most of the patches should be more or less self-explanatory. But please feel free to ask if something looks strange. I will just mention one problem I had, that I think needs a cleaner solution. This is marked "XXX_UB" in the patches below. The problem is the readline library in NetBSD. There is one readline in the base system (/usr/include and /usr/lib) but that is not the GNU readline that GHC expects. Instead the readline in /usr/pkg/include and /usr/pkg/lib must be used. The GCC in NetBSD does not include the /usr/pkg paths by default, so we must pass explicit -I/-L/-R all the time when using it. In particular this: -L/usr/pkg/lib -Wl,-R/usr/pkg/lib needs to go into hslibs/util/util.conf.in. And the same needs to go into ghc/rts/rts.conf.in for libgmp. I had to invent two new configure variables to make this work, ExtraLdOptsReadline and ExtraLdOptsGmp. Sofar this is OK I think, other systems should be able to use these too if they have readline or gmp installed in non-standard places. However, the problem is how to set these variables in the configure script. Below you can see the hack I did for NetBSD, but that is not very elegant. Maybe a better solution would be to add --with-readline=... and --with-gmp=... options to the configure script? This would at least partly solve the problem. I will also update the NetBSD package (port) with these patches. I think I will try to keep the package booting from .hc files rather than going the "first download small binary bootstrap kit" route that you guys seem to have chosen for FreeBSD nowadays. It seems to me that although booting from .hc files is very fragile business it has the advantage that it makes the package less sensitive to the exact OS versions involved (in particular the version the binary bootstrap kit was built on).

Please feel free to file a bug, we'll get around to it next time I have the profiling system paged in ;-) Cheers, SImon

profiling question
by Amanda Clare 26 Mar '03

26 Mar '03

I think this question was asked by someone else as part of another thread back in January, but I couldn't find an answer on the list archive. What do the zeros for "entries" mean in a time profiling report? If I want to know why "getAppropriatePreds" takes up so much time (14.7%) in my code, does the zero mean an overflowed count or that the cost centre has never been entered? I'm using 5.04.2 on Linux, and my program is compiled with -O -prof -auto-all. compose InfrequentCheck 1137 12280580 2.1 2.5 2.1 2.5 align InfrequentCheck 1127 0 3.7 6.2 8.3 6.7 align2 InfrequentCheck 1139 8577943 0.4 0.0 0.4 0.0 lookupModeArgs InfrequentCheck 1136 86747940 4.2 0.4 4.2 0.4 getAppropriatePreds InfrequentCheck 1126 0 14.7 6.6 14.7 6.6 Amanda
