Without this, an invocation like:
sudo ansible-playbook foo.yml
Where foo.yml uses setns, could inherit the HOME environment variable
from the external non-root user, which broke /usr/bin/mysql_upgrade and
plenty more.
* 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.
Ideally it would be possible to specify a callback function, but this is
not possible for proxied connections. So simply provide the 3 most
useful modes, defaulting to the most secure.
Closes#127. Closes#134.
machinectl does not support any sensible form of pipe to the child
process, so it is necessary to bypass it when talking to a systemd
container (see systemd/systemd#8850).
This can also form the basis for issue #223, where the post-fork
namespace switching dance required to connect to the Pythonless
container will be the same.
This change blocks off 2 common scenarios where a race condition is
upgraded to a hang, when the library could internally do better.
* Since we don't know whether the receiver of a `reply_to` is expecting
a raw or pickled message, and since in the case of a raw reply, there
is no way to signal "dead" to the receiver, override the reply_to
field to explicitly mark a message as dead using a special handle.
This replaces the serialized _DEAD sentinel value with a slightly
neater interface, in the form of the reserved IS_DEAD handle, and
enables an important subsequent change: when a context cannot route a
message, it can send a generic 'dead' reply back towards the message
source, ensuring any sleeping thread is woken with ChannelError.
The use of this field could potentially be extended later on if
additional flags are needed, but for now this seems to suffice.
* Teach Router._invoke() to reply with a dead message when it receives a
message for an invalid local handle.
* Teach Router._async_route() to reply with a dead message when it
receives an unroutable message.
This permits graceful shutdown of individual contexts, without tearing
down everything.
Update mitogen.parent.Stream to also wait for the child to exit, to
prevent the buildup of zombie processes. This introduces a blocking wait
for process exit on the Broker thread, let's see if we can get away with
it. Chances are reasonable that it'll cause needless hangs on heavily
loaded machines.
