Validate of GHC HEAD freezes on FreeBSD

Hello,

The "validate" script against GHC HEAD freezes on FreeBSD 9.1.
After sync-all, I did as follow:

----------------------------------------------------------------
% config_args="--with-iconv-includes=/usr/local/include
--with-iconv-libraries=/usr/local/lib --with-gmp-includes=/usr/local/include
--with-gmp-libraries=/usr/local/lib --with-gcc=/usr/local/bin/gcc47" CPUS=10 sh validate
----------------------------------------------------------------

This stopped quickly due to this problem:
	http://hackage.haskell.org/trac/ghc/ticket/7592

Then I executed "validate" with "--no-clean" again.

----------------------------------------------------------------
% config_args="--with-iconv-includes=/usr/local/include
--with-iconv-libraries=/usr/local/lib --with-gmp-includes=/usr/local/include
--with-gmp-libraries=/usr/local/lib --with-gcc=/usr/local/bin/gcc47" CPUS=10 sh validate --no-clean
----------------------------------------------------------------

GHC could be compiled and tests started. But this resulted in:

----------------------------------------------------------------
cd ../../libraries/base/tests && '/usr/home/kazu/work/ghc/bindisttest/install   dir/bin/ghc'
-fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-db -rtsopts
-fno-ghci-history -o qsemn001 qsemn001.hs    >qsemn001.comp.stderr 2>&1
cd ../../libraries/base/tests && ./T5962    </dev/null >T5962.run.stdout 2>T5962.run.stderr
cd ../../libraries/base/tests && ./5943    </dev/null >5943.run.stdout 2>5943.run.stderr

Re: Validate of GHC HEAD freezes on FreeBSD

Hi,

I confirmed that testsuite/timeout/install-inplace/bin/timeout.py does
not receive SIGALRM, so it is waiting forever.

Any suggestions to fix this?

Re: Validate of GHC HEAD freezes on FreeBSD

OK. I found an alternative timeout command written in Haskell.  And
insert "unblockSignals fullSignalSet" to it. Now "validate" can
finish.

I guess that one process (possibly GNU make) set signal mask and its
children inherit it. What is a right solution for this?

Re: Validate of GHC HEAD freezes on FreeBSD

Hi,

When I execute the following command (after GHC is build):

	% THREADS=1 sh validate --testsuite-only

the following test command always freezes:

	cd ./concurrent/should_run && '/usr/home/kazu/work/ghc/bindisttest/install   dir/bin/ghc'
-fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-db -rtsopts
-fno-ghci-history conc070.hs --interactive -v0 -ignore-dot-ghci +RTS -I0.1 -RTS  
<conc070.genscript 1>conc070.interp.stdout 2>conc070.interp.stderr

The GHC command is consuming CPU 100%.

I tested this GHC 4.6/GHC 4.7 to make GHC and GNU make 3.81/3.82. But
nothing changed.

Does nobody execute the "validate" script on FreeBSD before?

Re: Validate of GHC HEAD freezes on FreeBSD

Hi,

Even testsuite for GHC 7.4.2 ("gmake fast") freezes:

* Consuming CPU 100%
	- compiling conc070.hs
	- 367_letnoes
	- throwto001
	- Chan002

* Waiting for somting forever
	- signals004

I can reproduce this phenomena both for GHC HEAD and GHC 7.4.2 100%.

I have been running builder clients for both the FreeBSD head [1,2]
and stable [3,4] branches, and they did not show these problems.
Although I admit that their current setup is rather conservative, I am
using an old (well, the oldest supported) release, 8.1 with GCC from
the base system (4.2.1).  It is because I would like to produce
vanilla tarballs that could be run on both older 8.x and newer (9.x,
10.x) systems.

On a related note, I have just (about a month ago) switched to GCC 4.6
for the GHC maintained in the FreeBSD Ports Collection (7.4.2, as part
of the Haskell Platform), and I did not experience any problem with
it, I am currently using it on my netbook, together with numerous
ports I have for it.

But I will look into the problems you have described, I am obviously
for fixing these up.

Thank you for your reply. 

Just in case, I would summarize what I'm talking about. There are two
issues on FreeBSD:

1) Building GHC stops

       This is the problem which we are discussing in
       http://hackage.haskell.org/trac/ghc/ticket/7592

2) Tests freeze

       I confirmed that GHC 7.4.2, GHC HEAD, GHC 7.6.2RC2 has the same
       problem.

Could you please file a ticket about this as well?
