Greetings, Thanks for the reply and the fix. It may be pointless to bring it up if chicken-setup has already been rewritten, but i do not get the infinite loop for every package:
$ chicken-setup -f rss File rss.egg or rss.setup not found in the download directory. Do you want to download .egg archive ? (yes/no/abort) [yes] downloading required extensions (ssax) ... downloading ssax.egg from (www.call-with-current-continuation.org eggs/3 80) installing required extensions ... downloading ssax.egg from (www.call-with-current-continuation.org eggs/3 80) .. downloading rss.egg from (www.call-with-current-continuation.org eggs/3 80) . $ In any case, I look forward to getting on the intarweb with Chicken 4 :-) --underspecified On Mar 28, 2009, at 6:39 PM, Alex Shinn wrote: Hi, underspecified <[email protected]> writes: Under chicken 3.4.0, I have noticed that I can make chicken-setup enter into an infinite loop by telling it to fetch, but not install the http egg. I posit that the cause is a circular dependency somewhere among http's many dependencies, because eggs like rss with simpler dependencies do not loop. The dependency tree in this case looks like: http (regex-case url openssl) regex-case () url (coerce uri) coerce (miscmacros misc-extn) miscmacros () misc-extn (stack miscmacros) stack () uri (coerce miscmacros synch lookup-table) synch () lookup-table (miscmacros misc-extn) openssl () There's no circular dependency (that would arguably be a bug in the eggs themselves, though chicken-setup should try to handle it gracefully), just some diamond inheritance, but it turns out the bug is triggered for any egg with any dependencies. I've checked in a simple fix which conditions out running "install" on downloaded dependencies when -fetch is being used. Note this ugly mess has been rewritten in the upcoming Chicken 4 and the setup program renamed to chicken-install. Note also that the "http" egg also has an improved version in Chicken 4 called "intarweb" :) -- Alex
