I'm talking about unattended automated builds, so tweaking isn't an
option. On the other hand breaking the package environment isn't so bad,
because I'm throwing it away after each build.
I'm not convinced that we should try to build packages at any price.

It is sbv-2.2 that has that constraint.

Hi all,
All cabal installs using cabal-install-0.10.2 are currently failing
for us. This is due to the cabal file for HUnit-1.2.5.0, which was
recently uploaded to hackage. The ouput I'm getting from cabal is
just:

Resolving dependencies...

For what it's worth, I've been maintaining a fork for personal use for quite a

That doesn't sound very safe. How does it handle all the DoS attacks

Hi Erik,
A similar thing happened to me with the GraphViz package. As Duncan
explained to me, the problem is that Cabal-1.10.0.0 (and I believe also
1.10.1.0) incorrectly reports an error when conditionals are used in
test suites.
Upgrading to Cabal-1.10.2.0 (or cabal-install-0.14.0 with

So is it just orphaned and anyone can upload? That does not sound right, also
considering that lambdabot is used on the IRC channel, it'd be nice to have a
more structured way to push fixes and
The irc server it runs on has about 10 users, all of whom I know and trust, so
I have not tested it extensively but it should be as safe as anything else

do so in safe mode. As long as you don't trust any packages
Hi Martijn,
Yes, upgrading will obviously fix things (we do use 0.14 on our
development machines), but we have not set up any infrastructure for
building a custom cabal on production servers. We just use the one
from the Ubuntu repositories, which uses Cabal 1.10.1.0 on oneiric. So

Well, to me it wasn't entirely obvious that upgrading to Cabal-1.10.2.0
fixes the problem for cabal-install-0.12, and I still think this is a
good
I should probably be more clear - it supports all the same resource limiting
mechanisms as Mueval because it uses Mueval (modified to support Safe Haskell).

Just following up to my problem, I was seeing lots of hangs in various
places in my program when it was built with the threaded runtime.
I eventually tracked every single hang back to calls to MissingH's
System.Cmd.Utils, including pipeFrom, pipeTo, pipeBoth, and pOpen.

Hi,
Say I have a package that only appends
--constraint=template-haskell==2.7.0.0
--constraint=warp-tls==1.2.1 could I install it. Now I want to
release the package, then how could I have these constraint into the
.cabal so the user would not get troubled?
