Package manager hangs on git operations that require a password

[toivoh]

Operations in the Pkg module that perform git operations that require a password seem to hang consistently for me on this computer (Fedora 16), and I have to interrupt them with ctrl-C.

For instance,

julia> Pkg.update()
^C
 in cd at file.jl:181
 in update at /work/toivo/program/julia2/base/pkg.jl:349

To compare, if I try to pull from my METADATA fork manually, it asks for a password:

> pwd
/home/toivo/.julia/METADATA
> git pull
Enter passphrase for key '/home/toivo/.ssh/rata/id_rsa': 
Already up-to-date.

I guess that Pkg.update() gets stuck on the password question, that doesn't get through to the user?

Ah, this hadn't occurred to me since I use an ssh agent consistently. I could maybe have Julia automatically start an ssh agent and use it. In the mean time, if you can start your own ssh agent, you'll be much happier with life in general. I never enter passwords to ssh anywhere :-)

[toivoh]

Thanks for the tip :) I'll try it.

Pkg.update used to work for me, now I get this:

julia> Pkg.update()
Already up-to-date.
Username for 'https://github.com': 
^C
 in wait at process.jl:126
 in wait at process.jl:626

 in anonymous at no file:348
 in cd at file.jl:176
 in update at /home/jeff/src/julia2/julia/base/pkg.jl:347

It hangs and I ^C'd it. A couple things might have changed in my setup; I was added to Winston.jl and I have a couple packages on master in the "working on it" state.

It's trying to use the https:// protocol which requires a username. It should use the git:// protocol and I'm unsure why it would switch. Can you send me a tarball of your .julia directory?

[JeffBezanson]

Ah, it's the MCMC package. It's the only one with an https url.

[StefanKarpinski]

Fixed in METADATA. Adding and removing it should fix the problem.

[JeffBezanson]

Now I get this:

julia> Pkg.rm("MCMC")

 in rm at /home/jeff/src/julia2/julia/base/pkg.jl:112

MCMC doesn't even use ArgParse.

[StefanKarpinski]

Sorry about that. That should be fixed by running Pkg.Metadata.gen_hashes().

[JeffBezanson]

Oh dear:

julia> Pkg.Metadata.gen_hashes()
fatal: Not a git repository: 'METADATA/.git'

[StefanKarpinski]

Bah. You need to be in the right place for that to work. Just pull and try again. I pushed a fix.

[JeffBezanson]

Nice, that is helpful.

You know what's coming...

[StefanKarpinski]

Jesus. Ok, please send me a tarball of your .julia directory. I think several other people have had this and I'm now going to sit down and make sure it never happens again.

i think you should be able to type a password when prompted now, stdin is being passed to the child process
