Leaving this for somebody else to triage for now.


Some ideas to help bug reporting (1-4 may also help for feature 
requests):

1. What darcs version are you using? (Try: darcs --exact-version)

2.7.98.3 (beta 3)

2. What operating system are you running?

MacOS X (10.7.3)

3. What were you doing? (eg. what darcs commands)

darcs get http://joyful.com:/repos/hledger --lazy

4. What behaviour were you expecting?

Fetched repo, nothing eventful

5. What went wrong?

If I save this list of hash failures to a file and cut out everything but 
the hashes, I can automatically compare them.

All hashes seem to be correct

for i in `cat /tmp/hmm`; do zless ~/.darcs/cache/pristine.hashed/$i | 
shasum -a 256; done | sed -e 's/  -$//' > /tmp/hmm2

Here's what happens when I try this bypassing the rest of the cache 
system:

If I darcs get --lazy that repo yet again, it succeeds.  Now if I darcs 
check it, I get hash failure messages for the patch files.  I tried 
checking the hash manually at it seemed fine.

Here I'm wondering if the hash checker is confused by the prefixes in the 
filename, ie. 0000007642-
2973d4a117b9a036eaaf0db6e13675afb1b2b66c34596a7e470e04a3bc93b955 for a 
file with hash 
2973d4a117b9a036eaaf0db6e13675afb1b2b66c34596a7e470e04a3bc93b955.  If so, 
that's a tiny/easy-to-test-for bug

Thanks for opening this Eric. I found that the failures are due to the 
repo url being redirected. Getting the repo directly from its new url 
works as expected. 

Is this a bug ? HTTP log attached in case it helps anyone.
