PlayContext.delegate_to is the unexpanded template, Ansible doesn't keep
a copy of it around anywhere convenient. We either need to re-expand it
or take the expanded version that was stored on the Task, which is what
is done here.
This change is relatively incomplete -- ideally we could snapshot
os.environ and /etc/environment at startup and respect key deletions
too, but that's a lot more work. Wait for a bug report instead.
Closes#338.
* ansible: use unicode_literals everywhere since it only needs to be
compatible back to 2.6.
* compat/collections.py: delete this entirely and rip out the parts of
functools that require it.
* Introduce serializable Kwargs dict subclass that translates keys to
Unicode on instantiation.
* enable_debug_logging() must set _v/_vv globals.
* cStringIO does not exist in 3.x.
* Treat IOLogger and LogForwarder input as latin-1.
* Avoid ResourceWarnings in first stage by explicitly closing fps.
* Fix preamble_size.py syntax errors.
The OpenShift installer modifies /etc/resolv.conf then tests the new
resolver configuration, however, there was no mechanism to reload
resolv.conf in our reuseable interpreter.
https://github.com/openshift/openshift-ansible/blob/release-3.9/roles/openshift_web_console/tasks/install.yml#L137
This inserts an explicit call to res_init() for every new style
invocation, with an approximate cost of ~1usec on Linux since glibc
verifies resolv.conf has changed before reloading it.
There is little to be done for users of the thread-safe resolver APIs,
their state is hidden from us. If bugs like that manifest, whack-a-mole
style 'del sys.modules[thatmod]' patches may suffice.
The module name comes from YAML via Jinja2.. it's always Unicode. Mixing
it into a temporary directory name produces a Unicode tempdir name,
which ends up in sys.argv via TemporaryArgv.
This is a partial fix, there are still at least 2 cases needing covered:
- In-progress connections must have CallError or similar sent to any
waiters
- Once connection delegation exists, it is possible for other worker
processes to be active (and in any step in the process), trying to
communicate with a context that we know can no longer be communicated
with. The solution to that isn't clear yet.
Additionally ensure root has /bin/bash shell in both Docker images.
