- Avoid mutable kubectl_args class member
- Use six.iteritems
Reverts 49736b3a, large file copies can't avoid the RTT.
The parent stack must be blocked while FileService progresses, as unlike
the small file path, it does not make a snapshot of the (possibly
temporary) file passed by the action plug-in. So we need to keep that
file alive while the service runs.
Add a new integration test and a new soak test to cover both.
* Always enable the faulthandler module in the top-level process if it
is available.
* Make MITOGEN_DUMP_THREAD_STACKS interval configurable, to better
handle larger runs.
* Add docs subsection on diagnosing hangs.

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.
Calls to connect.put_file() where the file is sufficiently small enough
to fit in a single RPC proceed without waiting for an RPC response. If
the write fails the target context will log an exception, and any
subsequent step depending on the written file will fail.
I verified every built-in action plugin for file transfer calls, and
they all depend on the transferred file in the following step, so this
should be safe.
Reduces template/copy actions to 2-RTT, loop-20-templates.yml runtime
reduced from 30 seconds to 10 seconds over a 250ms link compared to
v0.2.2, and from 123 seconds compared to vanilla with pipelining
enabled.
When running any kind of script, rewrite the hashbang like Ansible does,
but subsequently ignore it and explicitly use a fragment of shell from
the ansible_*_interpreter variable to call the interpreter, just like
Ansible does.
This fixes hashbangs containing '/usr/bin/env A=1 bash' on Linux, where
putting that into a hashbang line results in an infinite loop.
* 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.
This is like FileService but blocks until the file is pushed by a parent
context, with deduplicating behaviour at each level in the hierarchy. It
does not stream large files, so it is only suitable for small files like
Python modules.
Additionally add SerializedInvoker for use with PushFileService, which
ensures all method calls to a single service occur in sequence.
To support detach, we must be able to preload the target with every
module it will need prior to detachment. This implements the
intermediary part of the process (i.e. the Ansible fork parent) --
receiving LOAD_MODULE/FORWARD_MODULE pairs and ensuring they reach the
child.
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.
mitogen/master.py:
Annotate forwarded log entries with their original source, logger
name, and message.
ansible:
mark stderr in red with -vvv
Tempting to make this appaer 100% of the time, but some crappy
bashrcs may cause lots of junk to be printed.
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.
Presently there is still no mechanism to add :attr:`tty_stream` to the
multiplexer after connection is successful, but for now it's not
expected that anything will be logged to it anyway.
Closes#148.
