Also use a lock file per host, rather than one global file lock.
Commit 9c0275a879 introduced a bug where the lock file was only being
unlocked by the child PID of the resulting fork done in ansible-connection.
This causes delays when a large inventory causes a lot of contention on
that global lock. This patch fixes the problem by ensuring the lock is
released regardless of the fork condition, and also to use a lock file
based on the remote address of the target host, removing the global lock
bottleneck.
Fixes#38892
(cherry picked from commit 7ce9968ce1)
* Fix debug logs failing with persistent connection
Fixes#33047
* As debug logs are written on stdout, it interrupts
the communication between ansible-connection(background)
process and main process. To avoid this add a string similar
to exactly identify the response string.
* Remove unwanted code in ansible-connection
* Fix review comments
* Fix spurious log emitted on ansible-connection stdout issue
* ansible-connection which runs as a background process sends a
json string (contains response received from remote device)
to foreground ansible-playbook process over stdout.
* If in case debug flag is enabled the connection_loader api
invoked from ansible-connection `ssh = connection_loader.get('ssh', class_only=True)`
results in emitting debug logs on stdout. This spurious log
interfere with the actual response and results in failure while
reading json string in ansible-playbook process
* To avoid this save stdout of ansible-connection and redirect it string
buffer to accumulate all the logs emitted by core API's
* Add these logs in `result['messages']` which is send a json string after reinstating saved stdout
* Remove unwanted code in ansible-connection
* Fix review comment
* Add parent pid to persistent connection socket path hash
Fixes#33192
* Add parent pid in persistent connection socket path hash
to avoid using same socket path for multiple simultaneous
connection to same remote host.
* Ensure unique persistent socket path for each ansible-playbook run
* Fix CI failures

down at the end of the play run. This change also includes an update to
properly honor the reset_connection meta handler.

Currently socket path is send from `ansible-connection` (running as background
process) over stdout. This can conflict with debug logs that are also send on
stdout resulting in incorrect socket path received by the main process.
To avoid this add a socket path delimiter string which is recevied by
main process and socket path is retrieved based on delimiter string.
This implementation will change in future when ansible-connection
framework is made more robust.
On Python3 and Python2 use pickle slightly differently so we need to be
explicit about some things.
If pickles could be shared between python2 and python3, as in
ansible-connection and the pickle cache, we need to specify the protocol
to use when dumping and the encoding to use for byte strings when
loading.
The dumping protocol needs to be no higher than 2 as python-2 only
supports up to protocol 2. The encoding should usually be 'bytes' so
that python2 str type becomes python3 bytes type. However, doing this
means that we must make sure that the objects being serialized properly
make their strings into text strings except when they're supposed to be
bytes. If strings are improperly byte strings, they may cause
tracebacks on the receiving end
Fix for persistent connection plugin on Python3. Note that fixes are also needed to each terminal plugin. This PR only fixes the ios terminal (as proof that this approach is workable.) Future PRs can address the other terminal types.
* On Python3, pickle needs to work with byte strings, not text strings.
* Set the pickle protocol version to 0 because we're using a pty to feed data to the connection plugin. A pty can't have control characters. So we have to send ascii only. That means
only using protocol=0 for pickling the data.
* ansible-connection isn't being used with py3 in the bug but it needs
several changes to work with python3.
* In python3, closing the pty too early causes no data to be sent. So
leave stdin open until after we finish with the ansible-connection
process.
* Fix typo using traceback.format_exc()
* Cleanup unnecessary StringIO, BytesIO, and to_bytes calls
* Modify the network_cli and terminal plugins for py3 compat. Lots of mixing of text and byte strings that needs to be straightened out to be compatible with python3
* Documentation for the bytes<=>text strategy for terminal plugins
* Update unittests for more bytes-oriented internals
Fixes#24355
When ansible-connection forks the process, it changed the working
directory to /. This patch will prevent ansible-connection from
changing the working directory in the forked process.
This will now print a log message that displays how long the ssh
connection took to establish to the remote device. If the connection
established time is exceed it will also print a message to the log file
that the connection attempts have exceed.
Updates default connection retries to 30
fixes#22319
* replaces persistent connection digest with _create_control_path()
* adds _ansible_socket to _legal_inputs in basic.py
* adds connection_user to play_context
* maps remote_user to connection_user when connection is local
* maps ansible_socket in task_vars to module_args _ansible_socket if exists
adds more logging to handle display being called from plugins. Also
rearranges some of the exception handling to better catch exceptions and
log to local syslog
* sends the serialized play_context into an already established connection
* hooks the alarm_handler() method in the connection plugin if it exists
* added configuration options for connect interval and retries
* adds syslog logging to Server() instance
This update will send the updated play_context back into an already
established connection in case privilege escalation / descalation activities
need to be performed. This change will also hook the alarm_handler() method
in the connection instance (if available) and call it in case of a
sigalarm raised.
This update adds two new configuration options
* PERSISTENT_CONNECT_INTERVAL - time to wait in between connection attempts
* PERSISTENT_CONNECT_RETRIES - max number of retries
