git clone fails with HTTP-error 415
Closed, ResolvedPublic

Description

I know that the hosted repo feature is fairly new and needs some testing, but thats what I want to do :).

I created a new repo in the webinterface and then tried to clone this repo.

This is the output I get:

E:\temp>git clone https://bk-dev.hacked.jp/diffusion/T/ testrepo
Cloning into 'testrepo'...
efrror: RPC failed; result=22, HTTP code = 415
atal: The remote end hung up unexpectedly

Looking at the code of git-http-backend, 415 means that the content-type is wrong. Looking even further at DiffusionServeController::serveGitRequest. It seems to me that the content-type is just pushed through.

Is this a bug of diffusion or just my server having some issues?

I'm using git version 1.8.3.msysgit.0 as the clone client and git version 1.7.10.4 is on the server.

Can I enable some kind of logging, that shows me what env is passed to the git-http-backend executeable?

We should just be shoving this through unmodified. There's no real logging, but you can add something like this:

phlog(print_r(array(
  'value1' => $value1,
  'value2' => $value2,
), true));

...to serveGitRequest and then check your webserver error log (usually /var/apache/error.log or similar, if under apache).

One other user has reported something similar, although we also have several who can clone things fine, so it might be a config/version issue. Let me know if you figure anything out.

Ok, found out why this fails. $_SERVER does not contains HTTP_CONTENT_TYPE. $_SERVER looks like that for the request:

It seems Content-Type is a bit special in this case: http://www.php.net/manual/en/reserved.variables.server.php#110763

What about using getallheaders instead of your approach? I have attached a patch for this, which makes it work here™.

I don't want to use getallheaders() because we can't unit test that (we have no way to control what it returns). I'll accept a patch to special-case Content-Type / Content-Length, though, if you want to do that. Thanks for figuring this out!
