Cabal client reinstalled with "patched" HTTP-4000.0.8 was still having occasional failures today. My proxy-POC.hs always succeeded, while cabal failed quite often with familiar
cabal: Codec.Compression.Zlib: premature end of compressed stream
This means that proxy-POC.hs is not trustworthy: it doesn't expose the bug in 100% cases.
I am going to roll back even further tomorrow: I'll patch [1] cabal-install to use strict ByteStrings and see if /that/ does the job. (I'm not sure in anything any more.)

Strict bytestrings in cabal-install do the job, yes.
I've installed squid proxy server. Gotta make this bug exposable...
Downloading through local squid did not manifest the bug. * * * Sigbjorn, I am stuck. If you have some idea on how to pursue this bug (print debugging with Debug.Trace?), I'll be delighted to test it. The bug is reproducible from within office LAN (read: ``business hours, 8 am to 16 pm UTC''): $ cabal update -v3 Downloading the latest package list from hackage.haskell.org Sending: GET http://hackage.haskell.org/packages/archive/00-index.tar.gz HTTP/1.1 Proxy-Authorization: Basic SG93IGFyZSB5b3U/ User-Agent: cabal-install/0.6.2 Host: hackage.haskell.org proxy uri host: xproxy, port: :3128 Creating new connection to xproxy:3128 Received: HTTP/1.0 200 OK Date: Mon, 23 Nov 2009 12:15:23 GMT Server: Apache/2.2.3 (Debian) Last-Modified: Mon, 23 Nov 2009 01:21:45 GMT ETag: "388dda-141754-a6117c40" Accept-Ranges: bytes Content-Length: 1316692 Content-Type: application/x-tar Content-Encoding: x-gzip X-Cache: MISS from xproxy.foo.bar.ua X-Cache-Lookup: MISS from xproxy.foo.bar.ua:3128 Via: 1.1 xproxy.foo.bar.ua:3128 (squid/2.7.STABLE6) Connection: close Downloaded to /home/vvv/.cabal/packages/hackage.haskell.org/00-index.tar.gz cabal: Codec.Compression.Zlib: premature end of compressed stream Have fun! -- vvv
