* When using PRSERV_HOST = "localhost:0" inside
Docker container (tested with ubuntu 20.04 and 21.04) the
self.loop.run_until_complete never completed, so self.address
wasn't ever assigned few lines bellow and then
self.port = int(self.prserv.address.rsplit(':', 1)[1])
in lib/prserv/serv.py caused a bit ugly exception:

* the issue was caused by "localhost" being resolved as IPv6 address ::1

update is_local_special to allow that

::1 localhost ip6-localhost ip6-loopback
even when ipv6 is disabled in dockerd as reported in:
https://github.com/docker/for-linux/issues/250
* add a check for self.prserv.address to provide better error message:

when something bad happens, but in this case you still need to read
bitbake-cookerdaemon.log to see the actuall error, in this case:

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: https://docs.yoctoproject.org
Contributing
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
Mailing list:
http://lists.openembedded.org/mailman/listinfo/bitbake-devel

Testing:
Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions. You can run this with "bitbake-selftest". In particular the fetcher is well covered since it has so many corner cases. The datastore has many tests too. Testing with the testsuite is recommended before submitting patches, particularly to the fetcher and datastore. We also appreciate new test cases and may require them for more obscure issues.
