git problem with uvcvideo

[Németh Márton]

Hi,

I'm trying to fetch the uvcvideo from http://linuxtv.org/git/?p=pinchartl/uvcvideo.git;a=summary .
I tryied to follow the instructions but at the third step I get fatal error messages:

I also tried with the git:// link:

> v4l-dvb$ git remote rm uvcvideo
> v4l-dvb$ git remote add uvcvideo git://linuxtv.org//pinchartl/uvcvideo.git
> v4l-dvb$ git remote update

Am I doing something wrong?

The http:// URL seems not to be available at the moment. I don't know if it's 
a transient error or a deliberate decision not to provide git access through 
http://

Please try git://linuxtv.org/pinchartl/uvcvideo.git. The URL on the webpage 
has two / instead of one for some reason. Mauro, could that be fixed ?

No, it is not a decision. However, using http for -git has some issues.

The double bars were causing troubles with the git: url. 
I've fixed it at gitweb.

The git URL is working fine:

$ git clone -l --bare /git/linux-2.6.git/ uvcvideo && cd uvcvideo && git remote add uvcvideo git://linuxtv.org/pinchartl/uvcvideo.git && git remote update

 * [new branch]      master     -> uvcvideo/master
 * [new branch]      uvcvideo   -> uvcvideo/uvcvideo

However, the html URL is currently broken:

$ rm -rf uvcvideo/ && git clone -l --bare /git/linux-2.6.git/ uvcvideo && cd uvcvideo && git remote add uvcvideo http://linuxtv.org/git/pinchartl/uvcvideo.git && git remote update 
Initialized empty Git repository in /home/mchehab/tst/uvcvideo/uvcvideo/
Updating uvcvideo

Probably, the rewrite rules at the server for http are incomplete. I'll see if I can fix it.

cheers,
Mauro.

It seems removing the extra '/' helps:

v4l-dvb$ git remote rm uvcvideo
v4l-dvb$ git remote add uvcvideo git://linuxtv.org/pinchartl/uvcvideo.git
v4l-dvb$ git remote update
Updating origin

  origin/master
  uvcvideo/master
  uvcvideo/uvcvideo
v4l-dvb$ git checkout -b test uvcvideo/uvcvideo
Branch test set up to track remote branch uvcvideo from uvcvideo.
Switched to a new branch 'test'


Now I can start to build and test this branch.

Fixed. 

Basically, for http: to work, the http server shouldn't call gitweb handler. So, a different URL
is needed for gitweb and for git pull... Also, I needed to enable an post-update hook to be sure that
some references are generated after a push.

I've updated the gitweb to display the proper URL's.

Basically, the gitweb interface is available via http://git.linuxtv.org. 

So, for uvcvideo, we have:
	http://git.linuxtv.org/pinchartl/uvcvideo.git	(gitweb interface, for browsing)

For adding a remote to that tree, you should use either:
	git remote add uvcvideo git://linuxtv.org/pinchartl/uvcvideo.git
		or
	git remote add uvcvideo http://linuxtv.org/git/pinchartl/uvcvideo.git

Both is working, but using the git: URL is better. The http: URL should be used only when
behind a firewall that blocks the git port (tcp port 9418).
