Thanks!  I have been eager to try out 6.12.  Unlike many of the recent
snapshots, this one built and installed fine on Mac OS X 10.6 :).

Is there an extralibs tarball that I should use with this?  I installed the
release candidate without said tarball.  First, I noticed that my old
version of cabal-install could not parse the output from
ghc-pkg-6.12.0.20091010:

cabal: failed to parse output of 'ghc-pkg dump'

Then, when I tried to build the network package manually, I got this:

Building network-2.2.1.4...

dist/build/Network/URI.o )

I have downloaded  ghc-6.12.0.20091010-src.tar.bz2.
But where to read the release notes?
ANNOUNCE  shows ``version 6.10.1'', and lists the old features.
What is the difference of 6.12.1 w.r.to 6.10.4 ?

Yes, work is in progress on cabal-install to update it to work with GHC 
6.12.1.  For now you have to use Cabal manually (runhaskell Setup 
configure, etc.).



Then, when I tried to build the network package manually, I got this:

Building network-2.2.1.4...

I think you may need the darcs version of the network package.

No; extralibs no longer exist. Instead, we'll be recommending that most
users wait until a Haskell Platform release is available that comes with
the compiler.

I assume that's a 32-bit version. The problems manifest themselves

1. it says


The following options are all described in Section 4.15.3, “RTS
options to control the garbage collector”.
* The flag +RTS -N now automatically determines how many threads to
   use, based on the number of CPUs in your machine.


actually -N is decribed in "4.13.2. RTS options for SMP parallelism"

also, i propose to enable +RTS -N by default. Haskell is very popular
as multithreaded language, don't fool novices!


I don't think we're ready for that yet.  The current implementation 
assumes that it has access to the given number of cores, and performance 
degrades severely if it doesn't.  So for example, using -N2 on a 2-core 
machine may perform badly unless the machine is otherwise very quiet. 
I've been working on improving this, but it's quite difficult: using 
spinlocks and busy-waiting is a lot faster than using sleep/wakeup 
synchronisation when you really have all the cores, but when you lose a 
core things go haywire.  I've tried the usual "spin for a bit and then 
go to sleep" technique, but even that can adversely affect performance 
when you really do have all the cores, because sometimes we do have to 
spin for quite a long time.  The only proper solution is not to 
synchronise at all, which is what we're looking at now (CPU-independent GC).


You may notice this effect more with 6.12.1 because we turned on the 
parallel GC for generation 0 by default.  This improves performance for 
parallel programs a lot (see ICFP paper), but also means there are many 
more all-core synchronisation points, which in turn will really hurt if 
any of our threads is descheduled by the OS.


So right now, on a dual-core I'd recommend using -N2 -qg1 (don't use 
parallel GC in gen 0), or -N2 -H.



"The -gn RTS option has been removed, except that -g1 is still
accepted for backwards compatibility. "


why not ignore whole option for a 6.12.*?


Because people might be using -g1?

Cheers,
Simon

In section 1.5.2. Warnings there is a duplication:

"""

What I do is keep my default as /usr/bin/ghc, then when I install
testing versions I just rm the unversioned ghc scripts that get
installed in /usr/local/bin/ (because /usr/local/bin appears on my $PATH
first).

this one built and installed fine on Mac OS X 10.6 :).

Interesting, I thought there were still problems there.
I assume that's a 32-bit version. The problems manifest themselves  
only when you compile a 64-bit GHC.


That's incorrect.  The 32-bit version is only partially working.  GHCi  
dies with a bus error (after package loading) and various features  
that need the interpreter/dynamic loading (such as TH and annotations)  
die under certain circumstances.


Disclaimer: I didn't actually test this with 6.12.1RC1, but with  
6.13.  However, there shouldn't be any difference as I am not aware of  
any 6.12.1-specific Mac fixes.


Manuel

PS: I am chasing these bugs, but I don't have a lot of time for that  
at the moment, they are tricky bugs, and my Mac-fu is still pretty  
limited.  So, if anybody else likes to have a go with gdb and dtrace,  
please do so.

If you want to install the OSX .pkg then I don't know of a way to do
this. Installing one seems to uninstall the previous one for no good
reason.

If you're installing the Windows installer then you can choose the
installation directory, but you'll have to make the aliases yourself.

If you're installing one of the Linux bindists then you can use
./configure --prefix=/your/path
and again you will have to set up the aliases yourself.

And if installing from source you can likewise use
./configure --prefix=/your/path
and set up aliases yourself.

Please try the darcs version at http://code.haskell.org/network. If
that builds fine I can make a new release of network shortly.

Here is my tale of woe. I'm running this on Mac OS X 10.6.

I tried to install the syb-with-class package off of hackage, which
initially failed because of the changes to the template-haskell
package installed with 6.12.1rc1.

So I think to myself "Oh! I'll just put an upper bound on the version
of template-haskell used in the .cabal file for syb, and install the
old version off of hackage".

The current version of template-haskell installs fine on 6.12.1rc1
with a couple minor tweaks (to compensate for StringConstr not being
present in Data.Data anymore).

But then when I try to build syb-with-class against the old
template-haskell lib I get the following error:

Has anyone seen this before? Are there any tools I can use to peer
into .hi files to get more information about what could be wrong?

template-haskell is a one of the packages that we call "wired-in", 
because GHC needs to generate references to some of the things that it 
defines.  To make GHC independent of the version of the template-haskell 
package, we internally strip off the version number when referring to 
template-haskell.


Now, this doesn't completely explain the error you're seeing.  When it 
starts up, GHC has to decide which template-haskell package is the 
"wired-in" one, and my guess is that it picked the other one (because it 
is newer).  You could find out by running GHC with the -v flag.  I think 
GHC is assuming that when you have multiple versions of a wired-in 
package that the older ones are wrappers around the newer ones (like 
base-3 and base-4), but that assumption doesn't hold in your case.


Installing a new version of a wired-in package is going to be 
problematic, but we ought to be able to at least improve the diagnostics.


Cheers,
Simon

Does it make sense to do releases of the template-haskell package on
to hackage? It's a bit misleading if I can't then do anything to the
package that doesn't leave me broken.

(I guess I can `cabal unpack` into my GHC source directory to get a
different version ...)

I've made a new release of network that should work on 6.12

I'll try to get this up in a bug report on trac as soon as it's back
up, but in case I forget, here's the problem:

The attached Demo.hs compiles on 6.10, but not on 6.12rc1

The output --ddump-splices for 6.10:

>>>
Demo.hs:1:0:
   Demo.hs:1:0: Splicing declarations
   test
 ==>
   Demo.hs:6:2-5
   myFunction[aLQ] = Demo2.testFun []
Ok, modules loaded: Demo2, Main.
<<<

In 6.12rc1:

>>>
Demo.hs:1:0:
Demo.hs:1:0: Splicing declarations
test
  ==>
Demo.hs:6:2-5
myFunction[aNX] = testFun ""

Demo.hs:6:2:
Couldn't match expected type `[Char]' against inferred type `Char'
  Expected type: [String]
  Inferred type: [Char]
In the first argument of `testFun', namely `""'
In the expression: testFun ""
Failed, modules loaded: Demo2.
<<<

Note that what was spliced in as [] is now being spliced in as "",
which is incorrect.

Thanks for the quick fix - I've been running with the patch and have
happstack going with minimal changes (entirely TH related, I think).
