Attempting to extract Io to a Fedora x86_64 client using 
darcs-1.0.8-4.fc7.x86_64.rpm
fails with:
    ellson@ontap:build> darcs get --partial 
http://www.iolanguage.com/darcs/Io
    Copying patch 224 of 224... done!
    Applying patch 2 of 224... Unapplicable patch:

(No such file or directory)

Same command on an i386 system succeeded once, then failed the same way 
on a second test
(after rm -rf Io )

This may be a problem with the --partial option, which isn't descibed in 
the darcs manpage, BTW.

Doing a get without --partial succeeded twice in a row.

Sounds like a problem with the checkpoint patch.  I can't reproduce this,
it looks like maybe the Io developers have removed the checkpoint file?

I get:

$ darcs get --partial http://www.iolanguage.com/darcs/Io
Copying patch 185 of 636...

which suggests that the developers have removed the offending checkpoint
(and in fact, all checkpoints).  We can't tell what happened without this.

I don't understand whats going on here.   I get the same errors today.

I'm using darcs-1.0.8-4.fc7.x86_64 from Fedora-development distro.

    ellson@ontap:build> rm -rf Io
    ellson@ontap:build> darcs get --partial 
http://www.iolanguage.com/darcs/Io
    Copying patch 229 of 229... done!
    Applying patch 2 of 229... Unapplicable patch:
    Mon Nov 27 10:46:11 EST 2006  steve@dekorte.com
      * namespace cleanup
    darcs: ./libs/iovm/io/Debugger.io: openBinaryFile: does not exist 
(No such file or directory)

Then dropping --partial works OK:

    ellson@ontap:build> rm -rf Io
    ellson@ontap:build> darcs get  http://www.iolanguage.com/darcs/Io
    Copying patch 641 of 641... done!
    Applying patch 641 of 641... done.
    Finished getting.

But then I get this problem when I try to pull updates:
ellson@ontap:build> cd Io
ellson@ontap:Io> darcs pull http://www.iolanguage.com/darcs/Io

I used a normal browser and looked inside
http://www.iolanguage.com/darcs/Io/_darcs/checkpoints/ and that
directory is empty. Now, how comes your darcs finds a checkpoint
file...??? Is there some caching proxy in between your darcs and
the remote repo?

Or did darcs --partial "find" the checkpoint "<h1> The page your
requested has moved..."? But then it would surely have
complained about bad checkpoint format, wouldn't it?

Hm, something in the bug tracker ate parts of my last mail. The
quote extended above the [...], and I had a signature at the
end. ???

I see the same here using firefox.

Perhaps the pull problem is that there is no checkpoint?   I get the 
moved message from the empty directory:

The Io folks seem to have rebuilt their repository from scratch (i say this
because now there are 6 patches from a complete get).  Looks like we might never
get to the bottom of this.

Marking not-our-bug for lack of a better idea.

The old repo is at:

http://www.iolanguage.com/darcs/Io2

Btw, we've found we have to rebuild the repo ever 6 months or so to  
get around this problem.

hmm, I think you meant maybe
http://www.iolanguage.com/darcs/IoOld

For what it's worth, I was able to get --partial it with 1.0.9rc2
on MacOS X.

Yup, thanks.

The recent problem wasn't with getting, it was with either pushing or  
pulling to the repo. Darcs would just hang for hours at 100% cpu  
utilization.

I believe this isuse with partial repos and checkpoints is resolved in unstable
with darcs-2 and the --darcs-2 format.
