setup issue: cgit only shows summary page

setup issue: cgit only shows summary page

[luky-37]

Hey guys,


I've a probably stupid setup issue, I just can't figure it out and need
a fresh set of eyes:
I compiled cgit from source (@d6c405077) and installed it
on a Ubuntu VM together with nginx through fcgiwrapper.

When I open cgit in my browser it recognizes the repositories, etc,
but I only ever see the summary page with the list of repositories.

If I click on one of them ("/cgit/<repo>/" or "/cgit/cgit.cgi/<repo>/")
it does open in the browser but the content is always the summary page of
all repositories, never the actual repository itself.

Repositories are correctly discovered and for example the "idle" column shows
correct values, but I can't seem to open one of those repositories.


I triple checked file permissions, that doesn't appear to be the problem.

I've also attached strace to the fcgiwrapper process monitoring its cgit
children, and I don't see any permission problems.



cgitrc is:
#virtual-root=/cgit/
css=/cgit/cgit.css
logo=/cgit/cgit.png
favicon=/cgit/favicon.ico
remove-suffix=1
scan-path=/srv/git

and the relevant part of the nginx config is:

root /var/www/htdocs;

location /cgit/ {
		try_files $uri @cgitcgi;
}

location @cgitcgi {
		fastcgi_param ? DOCUMENT_ROOT $document_root;
		fastcgi_param ? SCRIPT_NAME /cgit/cgit.cgi;
		fastcgi_param ? QUERY_STRING ? ? ? ? ? ?$query_string;
		fastcgi_param ? REQUEST_METHOD ? ? ? ? ?$request_method;
		fastcgi_param ? CONTENT_TYPE ? ? ? ? ? ?$content_type;
		fastcgi_param ? CONTENT_LENGTH ? ? ? ? ?$content_length;
		fastcgi_param ? REQUEST_URI ? ? ? ? ? ? $request_uri;
		fastcgi_param ? SERVER_PROTOCOL ? ? ? ? $server_protocol;
		fastcgi_param ? GATEWAY_INTERFACE ? ? ? CGI/1.1;
		fastcgi_param ? SERVER_SOFTWARE ? ? ? ? nginx/$nginx_version;
		fastcgi_param ? REMOTE_ADDR ? ? ? ? ? ? $remote_addr;
		fastcgi_param ? REMOTE_PORT ? ? ? ? ? ? $remote_port;
		fastcgi_param ? SERVER_ADDR ? ? ? ? ? ? $server_addr;
		fastcgi_param ? SERVER_PORT ? ? ? ? ? ? $server_port;
		fastcgi_param ? SERVER_NAME ? ? ? ? ? ? $server_name;
		fastcgi_param ? HTTPS ? ? ? ? ? ? ? ? ? $https if_not_empty;
		fastcgi_pass ? ? ? ?unix:/var/run/fcgiwrap.socket;
}




I've played a lot with those fastcgi parameters in nginx, but I can't
seem to figure out a working combination.



Any hints on how to troubleshoot this properly would be greatly appreciated.



Regards,

Lukas

I think you either need to set PATH_INFO here *or* to avoid setting
SCRIPT_NAME.  CGit uses SCRIPT_NAME to decide whether to use path URLs
or the "url=" query parameter.  If it's using path URLs then you need to
have PATH_INFO specified as the full path (which must start with
$SCRIPT_NAME).

Note that I've never used fcgiwrapper so I don't know whether it will
set either of those automatically; I'm just going on how CGit behaves.

fcgiwrap uses SCRIPT_FILENAME (if set) and the concatenation of
DOCUMENT_ROOT and SCRIPT_NAME otherwise.

Suggestions for the nginx config: generally a default, sane set of
fastcgi parameters is available in the fastcgi_params file which you can
include with "include fastcgi_params;".

For a working fcgiwrap + nginx config, see:

Thanks for these hints. In the end, I had to intercept the fcgi requests
to understand whats going on exactly, and I found that nginx' try_files
resets PATH_INFO [1].

Configuring:
?fastcgi_split_path_info ? ? ? ^(/cgit/)(.*)$;
?fastcgi_param PATH_INFO $fastcgi_path_info;


did the trick for me, without removing try_files.
