Peter Kjellerstedt 9589076fed bitbake: fetch2/__init__: Disable pseudo in runfetchcmd()
If a fetcher, e.g., git, is run when pseudo is active it will think it
is running as root. If it in turn uses ssh (as git does), ssh too will
think it is running as root. This will cause it to try to read root's
ssh configuration from /root/.ssh which will fail. If ssh then needs to
ask for credentials it will hang indefinitely as there is nowhere for it
to ask the user for them (and even if there was it would not access the
correct private keys).

The solution to the above is to temporarily disable pseudo while
executing any fetcher commands. There should be no reason for them to be
executed under pseudo anyway so this should not be a problem.

RP Ammendum:

We finally did get more information about how to reproduce this problem,
something needs to trigger bb.fetch2.get_srcrev() in a pseudo context,
for example when AUTOREV is in use or the recipe doesn't have a defined
SRCREV. That SRC_URI needs to be using protocol=ssh. This would trigger
an ls-remote of the remote repo and if that happens under pseudo, the
wrong ssh credentials may be attempted which can hang.

[YOCTO #12464]

Bitbake
=======

BitBake is a generic task execution engine that allows shell and Python tasks to be run
efficiently and in parallel while working within complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
stacks using a task-oriented approach.

For information about Bitbake, see the OpenEmbedded website:
    http://www.openembedded.org/

Bitbake plain documentation can be found under the doc directory or its integrated
html version at the Yocto Project website:

Please refer to
http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
for guidelines on how to submit patches, just note that the latter documentation is intended
for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org)
but in general main guidelines apply. Once the commit(s) have been created, the way to send
the patch is through git-send-email. For example, to send the last commit (HEAD) on current
branch, type:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org
