git clone ssh failing

mstonespeedy

Thanks for your continued help, @JonB.

With your script, I don't get a paramikolog.txt at all. Just the same HangupException.

Our company server reports:

Ubuntu 12.04.5 LTS (GNU/Linux 3.13.0-100-generic x86_64)
git version 1.7.9.5

I don't believe we use submodules. How do I tell?

JonB

Do you get any printout from the script? I am surprised you don't get any list of refs...

Perhaps also change the paramikolog.txt to os.path.expanduser('~/Documents/paramikolog.txt')

mstonespeedy

When I run the script with your source, it creates a paramikolog.txt file just fine. But when I use my source, apparently there's nothing to write because the file is never created. And no other output on the command line. All I get is a dulwichtests/.git folder with initialized files and folders.

JonB

That is surprising, because at a minimum, you should get a "logging started" message which is logged right off the bat by my script.

Then you should see some startup stuff, and the authentication negotiation..

JonB

Can you post a full traceback of your hangup error?

Can you exit/restart pythonista, then run the script directly(no stash)?

Incidentally, i can reproduce this error if I type in an incorrect repo path. Are you SURE you have the full and proper path? i.e if i change uicomponents to uicomponent, i get thto same error as you.

Try adding this right after the get_transport line, around 34:

proto, can_read = client._connect(b'upload-pack', host_path)
import time
time.sleep(1.0)
okay_to_read=can_read()
while okay_to_read:
	line=proto.read_pkt_line()
	if line:
		line=line.replace('\x00','')
		print(line)
	okay_to_read=can_read()

Thanks for your additional help, @JonB.

I've been trying this URL:

'ssh://user@git.myCompany.com/git/MyRepository.git'

I did some trial and error with your test script, since can_read() was always false. I finally got it to work with an extra slash after the host name, like this:

'ssh://user@git.myCompany.com//git/MyRepository.git'

I've never had to do this with the regular git client. Do you know if there is a reason for requiring the extra slash? If not, I can report it as a bug.

Relieved to finally have it working, though. Thanks again for your patience and help!

JonB

how odd. I would report it as a dulwich issue. I suspect a true git client may do some "normalization" such as adding the .git at the end.

mstonespeedy

Will do. Thanks again.
