Two general notes:

Current state of darcs 2.8 release?


Hello,

I'm looking forward to using the "packs" feature of darcs 2.8. The last
details about I can find about it on the blog and wiki indicate a
release sometime this past this summer.  What's the updated release status?

In related news, I opened a bug report regarding missing docs about
packs, and suggested what some improved docs might look like:

darcs 2.8 fails to build on FreeBSD 8.1


Hello,

I just tried "cabal install darcs-beta" on FreeBSD 8.1.
It started to compile darcs-beta-2.7.98.1. Ultimately, it failed like this:

src/HTTP.hs:11:42:
    Module `Network.Browser' does not export `setCheckForProxy

Perhaps darcs needs to declare that needs a newer version of HTTP.hs?

Oh my, that was complex. And not finished yet. And, interestingly, none
of the problems that I encountered had anything to do with
hashed-storage.

The ghc-6.10 builder presently succeeds. The ghc-6.12 builder fails and
it probably doesn't makes sense to attempt to fix it with the ghc-6.12
that I have installed at

Report after triaging 2.8 release blocker: what remains to be done


With a nod from Heffalump on IRC, I momentarily stepped into my old rule
of bug tracker czar and reviewed all the bugs tagged with the 2.8
milestone to see what could be done to move the release along.

Mostly I found things which weren't regressions from 2.5.1.
That is, we can push off addressing them until 2.10, and our quality
will be no worse than it was before, and all the fixes and features in
2.8 will actually get released. Indeed, many of the issues were things
that I had been pushed from the 2.4 release to the 2.5 milestone
previously. :)

In they end, there are less than 10 items left marked with the 2.8
release goal. They can be easily moved into 2 categories:

-- probably related to packs
-- probably not regressions since 2.5.1.

http://goo.gl/im3iE

It seemed clear from the review that --packs are not ready for
prime-time yet. They are barely documented and cause a number of
documented problems in the bug tracker.

Either this feature should be removed (which may be difficult, I
imagine), or the default should be --nopacks for 2.8 (probably fairly
easy). If the feature remains, it should be clearly marked as
experimental, perhaps with a link to related open tickets in the bug
tracker.

Oh dear! Thanks very much for your efforts.

Sounds good, as soon as we deal with an issue with non-ASCII filenames
triggered by GHC 7.2 (issue2095).

Petr, is reconfiguring buildbot as above something only you can do? I
can't find any instructions on the wiki.

Cheers,

Ganesh

Thanks for starting on this Simon!

One item I see on the list looks related to the build failure I'm
getting on FreeBSD 8.1 is this:

"bumped network and HTTP dependency upper version bounds"

My build failure with 6.10.4 was this:

"src/HTTP.hs:11:42:
    Module `Network.Browser' does not export `setCheckForProxy"

I looked into this further. The setCheckForProxy change seems to have
appeared in version 4000.0.8.

Darcs appears to correctly reflect this in setup.cabal:

    HTTP    >= 4000.0.8 && < 4000.2

In my ".cabal" directory, I see that 4000.0.4 has been downloaded,
unpacked and built. Yet, darcs/cabal didn't throw an error that that the
dependency was too low, and Cabal appears to have downloaded of
the HTTP library that is too old.

I'm using:

The trouble is not specifically related to darcs, but is part of an
ongoing fight with macports to set up a suitable environment for GHC
buildbotting.  Lately, I have been more successful than earlier, as a
result of using a more recent curl, but everything seems interlocked and
one part of the installation often affects other parts in unexpected and
undesirable manners. Ian (igloo) has suggested using "homebrew", another
packaging system for Mac OS X, but I haven't decided to take that plunge
so far.

In any case, darcs is not to blame, but thanks for your concern.

Concerning the building GHC version: I have earlier installed 6.10,
6.12, and also 7.0 via Mac OS X binaries supplied by the GHC HQ. The
6.10 version continues to work, but both the 6.12 and 7.0 GHCs fail, if
I also have the libiconv library from macports installed. See, for
example:

Since the macports libiconv seems needed to make the git installation
work, I have decided to attempt to rely on GHCs built from source.
Presently, I have working

At the risk of being unhelpful, I found my Haskell life less frustrating
when I abandoned MacPorts in favour of HomeBrew
