I added some logging to the pclzip class and it appears that the .tmp files it processes are empty. Jetty is the owner of the used directory.

I was able to fix the issue locally by changing the following line in class-http.php / _get_first_available_transport :

$request_order = array( 'curl', 'streams', 'fsockopen' );

to

$request_order = array( 'fsockopen', 'curl', 'streams' );

curl didn't work and streams threw an exception. fsockopen worked.

Hi,

Can you give us the exception thrown by streams please ? Thanks.

When using streams I get the following error logs when trying to install a theme :

I found now also the bug in the curl module. When using the options CURLOPT_RETURNTRANSFER and CURLOPT_FILE, the CurlResource class skips outputting to outputFile and returns the contents directly.

When CURLOPT_FILE is given, the output file serialization needs to be done. CURLOPT_RETURNTRANSFER needs to be handled later.

The problematic code is here :

    if (_isReturningData)
      return data;

    if (_outputHeaderFile != null) {
      FileModule.fwrite(env,
                        _outputHeaderFile,
                        _header.toInputStream(),
                        Integer.MAX_VALUE);
    }

    if (_outputFile != null) {
      FileModule.fwrite(env,
                        _outputFile,
                        data.toInputStream(),
                        Integer.MAX_VALUE);

    }
    else {
      env.print(data);
    }

Buffering to a bytearrayoutputstream or something like that might a solution here.

The streams bug appears in com.caucho.vfs.HttpStream getConnInputImpl() :

        // server/1963
        if (len != writeLength) {
          throw new IOException(L.l("Content-Length={0} but only received {1}",
                                    len, "" + writeLength));
        }

The usage of the variable _tempStream seems to be broken.
