[Savannah-hackers-public] vcs0 cgi errors ("502 bad gateway")

[Assaf Gordon]

Hello,

A user just reported the vcs0 gives "502 Bad Gateway":
 http://savannah.gnu.org/support/?109254

The immediate cause is nginx failure to connect to fcgiwrap:

   $ tail -n1 /var/log/nginx/error.log
   2017/02/10 10:58:20 [error] 3647#0: *370418 connect() to unix:/var/run/fcgiwrap.socket failed (11: 
Resource temporarily unavailable) while connecting to upstream, client: X.X.X.X,  server: 
git.savannah.gnu.org, request: "GET /r/freetype/freetype2.git/info/refs?service=git-upload-pack 
HTTP/1.1", upstream: "fastcgi://unix:/var/run/fcgiwrap.socket:", host: 
"git.savannah.nongnu.org"

I've restarted fcgiwrap and reloaded nginx, and it seems to work now.

Not clear why/what happened yet. Found nothing special in 'dmesg'.


Also, the user reported that this URL gives "404 not found":
   http://git.savannah.gnu.org/gitweb

that's because our nginx confs expects a trailing slash.
I've added a redirection in /etc/nginx/sites-available/git .

regards,
