is there a reason a bitbake "git" clone will hang while regular git works?

is there a reason a bitbake "git" clone will hang while regular git works?

[Robert P. J. Day]

  since the git fetcher code is part of bitbake, i figured i'd ask
here.  on more than one occasion now, when i've configured a build and
start fetching, the git fetch of the corresponding kernel source will
simply hang.

  for example, right now, i'm fetching for a dm814x-evm (using the
meta-ti layer), and the dir under git2 in the downloads directory
currently looks like this:

$ du -s *
4	branches
4	config
4	description
4	HEAD
40	hooks
8	info
12	objects
12	refs
$

and it hasn't changed for well over 10 minutes. the relevant part of
the recipe file:

SRC_URI +=
"git://arago-project.org/git/projects/linux-omap3.git;protocol=git;branch=ti81xx-master \
file://0001-ti814x-added-code-for-disabling-the-least-significan.patch \
            file://defconfig"

  however, as a test that git was still working properly, i simply
started a git clone of that SRC_URI and it's chugging away as i type.
and this has happened before -- that is, while the bitbake fetch/git
clone hangs almost immediately, i can generally use "git clone" from
the command line for that SRC_URI no problem.

  does that even make sense?  are the git options being used by
bitbake perhaps causing this?

Is it running a git clone or is it fetching a tarball from the source
mirror?

The options used by bitbake shouldn't be different in operation to the
ones you use on the commandline. You could poke around /proc/xxx/cmdline
to take a look...
