[pkg-lighttpd] Bug#345554: lighttpd: Seems to be related to the use of "+=" with alias.url

[Mike Paul]

Package: lighttpd
Version: 1.4.13-4
Followup-For: Bug #345554

I encountered this bug while trying to use lighttpd with dwww;
http://localhost/cgi-bin/dwww returns a 404 error.

I ran lighttpd under strace and found the following:

stat64("/usr/lib/cgi-bin/, /usr/lib/cgi-bin/dwww", 0xbfb4ca68) = -1 ENOENT (No such file or directory)

That string, with a comma and a space in the middle, is clearly not a
valid filename.  But if I change "+=" to simply "=" on the two
"alias.url" lines in 10-cgi.conf, the problem goes away and dwww works.
Apparently the use of "+=" causes it to try to combine the two alias
strings in this very nonsensical way.

It seems very strange to me that lighttpd tries to combine both alias
strings like this, when it seems to ignore the first one completely
unless the second one (inside the $HTTP["host"]=="localhost" block) is
given.  One could say that the real bug is the fact that the localhost
hack is needed in the first place.  But at least by changing "+=" to "+"
it can be made to work correctly.
