While happily installing prerequisites to build an app on Solaris
11, i enjoyed having
Mercurial already installed in the base
system.. except for a BIG issue: digest authentication was broken. I
tcpdump’ed the traffic exchanged between the mercurial client and the CGI
server and I saw that no Authorization header was sent, and obviously the
server refused to serve the hg repository.
Before reinstalling python, maybe from source and replacing the default installation or having side by side two different versions, with consequent nuisances and dirt around the system, I tried a very very small patch to urllib2.py that… amusingly enough, fixed my problem:
--- urllib2.py~ Fri Jan 25 02:35:59 2008
+++ urllib2.py Fri Jan 25 03:27:52 2008

auth_val = 'Digest %s' % auth
if req.headers.get(self.auth_header, None) == auth_val:
return None
- req.add_unredirected_header(self.auth_header, auth_val)
+ req.add_header(self.auth_header, auth_val)
resp = self.parent.open(req)
return resp
I’m no fscking python expert (but the language is interesting), so don’t ask me
WHY it works, i simply followed the add_header comment that said “this method
is useful for adding authentication headers” and replaced the
unredirected_header method with the former. I really don’t know why with
Python2.5’s urllib2 “everything works” even with that method, something must be
broken somewhere else. A diff between the two urllibs gave me nothing, I really
should learn Python one day or another.
I also found no information by googling keywords such as «solaris “http {authorization,authentication}” {urllib2,python} {broken,not working} mercurial» (shell interpolation intended), so I hope this post will be useful to someone ;).
Solaris looks like a nice beast, though. I’ll have to learn more about it as well. :).
