Re: Errors cloning over http -- git-clone and cg-clone fail to fetch a reachable object...

I got similar today; www.hawaga.org.uk is some apache server on linux, and piva.hawaga.org.uk, the client Mac OS X.

Feel free to hit the URL yourselves -- its a public webserver.

According to system profiler on piva:

   System Version:    Mac OS X 10.4.2 (8D37)
   Kernel Version:    Darwin 8.2.1

and

!582 [1] benc@piva:~/tmp$ curl --version
curl 7.13.1 (powerpc-apple-darwin8.0) libcurl/7.13.1 OpenSSL/0.9.7g  
zlib/1.2.3
Protocols: ftp gopher telnet dict ldap http file https ftps
Features: IPv6 Largefile NTLM SSL libz
!583 [1] benc@piva:~/tmp$

This is on an unpacked repository, so I would guess that none of the GETs for objects should be failing...

Note that it *doesn't* always error out on the same object:

When I run it lots of times in succession, it gets between 10 and 15 objects in before failing on something.

When I try with plain git:

!580 [1] benc@piva:~/tmp$ git clone http://www.hawaga.org.uk/ gitcompletion.git here defaulting to local storage area got a108bdc110dad770ec5c092759a8bc511790d21f walk a108bdc110dad770ec5c092759a8bc511790d21f got 912eb2baf57b70178c2e1f10df12eae911e1d748 got 261466f44dce8fb3cac4e0d0f1bf5a46fa84e07e walk 912eb2baf57b70178c2e1f10df12eae911e1d748 got f766b276eff3ec52ac3c0425b13c936d87c607ee got e05988e4a193f9eac2862ce6e67b19e3785bd8f1 got c99aa418704f576aad8249d042cd6afecf38afc4 got d743b178b82e9a8f10a1bf267d32d070e36c8046 got 96a0d6b6b182d978c04290f7c87049a5d3cc41b7 got 676bd846066cf3794796cadb258a23a76744819c got 2e04450bdc81b1380a8f75223d8ce8019400dd70 error: (curl_result = 3179232, http_code = 200, sha1 = 682cfbd4d75e204fada2cabe9e0f040e522ce61d) Getting pack list error: Getting alternates list error: Unable to find 682cfbd4d75e204fada2cabe9e0f040e522ce61d under http://www.hawaga.org.uk/gitcompletion.git/

but a curl by hand for one of the object URLs works:

!581 [1] benc@piva:~/tmp$ curl http://www.hawaga.org.uk/ 
gitcompletion.git/objects/68/2cfbd4d75e204fada2cabe9e0f040e522ce61d

and works each time when I run it repeatedly.
