cgit with busybox httpd

[Andreas Mahling]

sorry, I've missed sending to the list address

I wrote a script test.sh which prints the environment.
When called as http://git/cgi-bin/test.sh/xyz PATH_INFO ist set to '/xyz'
When called as  http://git/cgi-bin/test.sh/xyz/ 404 is thrown. So the
problem seems to be caused by httpd

hello John,

It seems the 404 is generated by httpd, I think because the url ends
with a slash httpd treats the part after cgit.cgi not as PATH_INFO (as
it should) but as a directory. So this seems more a fault of httpd to
me.

Sorry, but I don't understand how to put into QUERY_STRING what now
goes into PATH_INFO. Do you mean the virtual-root option in cgitrc?
It is already commented out in my setup, but cgit builds the url with
PATH_INFO part anyway.

best regards Andreas
