Re: freebsd-amd64-head (FreeBSD/amd64 HEAD (Gabor Pali)), build 556, Success

[Karel Gardas]

Hi,

due to recent switch to full testsuite run, our buildbots now provides a 
lot of output due to much more failing testcases. The case with FreeBSD 
buildbots even got so far, that server can't handle amount of data and 
leaks some binary trash to the log. I would really be curious if this is 
a leak of runtime memory and so it shows serious bug somewhere in GHC 
rts or what is it exactly... If you are curious investigate output 
attached to the last night freebsd buildots status emails.


Thanks,
Karel
PS: I'm assuming the builder infrastructure as run by Gabor on his 
server is still written in Haskell and compiled by GHC...

Hi Simon, Austin

https://phabricator.haskell.org/D698 should fix the build. validate runs 
cleanly through.

My apologies again, my last few builds were using ./validate --no-clean by my 
are-validating.mk was missing
so it wasn’t compiling with -Werror.

This must be fallout from the VEH handler change I pushed earlier -
5200bdeb26c5ec98739b14b10fc8907296bceeb9.

I'll try to fix/revert shortly.

Oops, that is indeed the case, thanks for calling my attention to
this.  I guess I shall only update the LLVM toolchain on the builders
and everything will go back to the normal.

It may be because the server was built with GHC 7.6.3.  Perhaps moving
to some more recent version, such as 7.8.3, could solve the problem.
It may also happen that is simply OS-specific, or the bug is in the
server's code directly.
What I can do for now is to rebuild the server with 7.8.3 and have the
clients running with the old LLVM to get the same amount of data.

Yes, that is right.

Gabor

LLVM failures

[Simon Peyton Jones]

These two LLVM tests are still failing consistently for me (on Linux).  I think 
Austin said this should not happen, and he would fix, but I can't find the 
thread.  Anyway, what should I do?

:

You are using an old version of LLVM that isn't supported anymore!

We will try though...

it looks like you’ll need to install llvm-3.6.

What distribution are you using, and what release of that in particular?
(Usually, the output of "lsb_release -a" is the easiest way to find that
out.)

in that case I suggest the following source for llvm-3.6, which is the
same that we use on Travis (all commands to be run as root):

First enable this repository to get a libstdc++ backport
$ add-apt-repository -y ppa:ubuntu-toolchain-r/test
Then add the llvm backports repository
$ echo 'deb http://llvm.org/apt/precise/ llvm-toolchain-precise-3.6 main' >> 
/etc/apt/sources.list
$ wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key | sudo apt-key add -
Then you can install the llvm package:
$ apt-get update
$ apt-get install llvm-3.6

Finally, you need to make sure that GHC’s configure finds these
binaries, e.g. by extending your PATH. You probably know better where to
put this in your configuration:
export PATH=/usr/lib/llvm-3.6/bin:$PATH

Greetings,
Joachim

Re: LLVM failures

[George Colpitts]

A side question, my understanding is that llvm-3.5 is  the "official" llvm
for ghc 7.10. Does anybody know if llvm-3.6 works with ghc 7.10?

George

I'm afraid that we won't have support for LLVM 3.6 until GHC 7.12 due to
non-backwards compatible syntax changes in LLVM's intermediate
language. With GHC 7.12 we will have precisely one supported LLVM
version which we will optionally ship with the GHC release. Depending
upon timing this will be either LLVM 3.6 or 3.7.

Cheers,

- Ben

Fwd: PSA: building HEAD with Nix/NixOS

[member MP2E]

Looks great, thank you! One question however, in one of the lines you have
this command:
'nix-build '' -A haskell-ng.compiler.ghcHEAD --run-env -I
/home/user'
Is nix-build supposed to be nix-shell? Usage afterwards seems to indicate
that it is, but I'm not 100% sure.

That was done yesterday (along with a restart), but apparently the
problem still persists.  I have also checked the posted file
("step.testsuite summary.output.txt") and it is placed to the web site
without any glitches, so perhaps the bug is somewhere in the mailer.
The attached files are translated to base64, which is probably
implemented by Ian's original base64-string package [1] and that is
what goes wrong.

I will study the code further.
