File add-salt-ssh-support-with-venv-salt-minion-3004-493.patch of Package salt
From 3fd6c0c6793632c819fb5f8fb3b3538463eaaccc Mon Sep 17 00:00:00 2001
From: Victor Zhestkov <vzhestkov@suse.com>

Subject: [PATCH] Add salt-ssh support with venv-salt-minion - 3004
(#493)
* Add salt-ssh support with venv-salt-minion
* Add some comments and drop the commented line
* Fix return in check_venv_hash_file
* Convert all script parameters to strings
* Reduce the size of minion response
Minion response contains SSH_PY_CODE wrapped to base64.
This fix reduces the size of the response in DEBUG logging
* Make VENV_HASH_FILE global
* Pass the context to roster modules
* Avoid race condition on loading roster modules
* Prevent simultaneous to salt-ssh minion
* Make ssh session grace time configurable
* Prevent possible segfault by GC
* Revert "Avoid race condition on loading roster modules"
This reverts commit 8ff822a162cc494d3528184aef983ad20e09f4e2.
* Prevent deadlocks with importlib on using LazyLoader
* Make logging on salt-ssh errors more informative
* Add comments about using salt.loader.LOAD_LOCK
* Fix test_loader test
* Prevent deadlocks on using logging
* Use collections.deque instead of list for salt-ssh
Suggested by @agraul
* Get proper exitstatus from salt.utils.vt.Terminal
to prevent empty event returns due to improperly detecting
the child process as failed
* Do not run pre flight script for raw_shell
