Python 2.7 ~ Python 3.x +are now supported transparently. Requirement is, however, that the SaltMaster should +have installed Salt, including all related dependencies for Python 2 and Python 3. +Everything needs to be importable from the respective Python environment. + +SaltSSH can bundle up an arbitrary version of Salt. If there would be an old box for +example, running an outdated and unsupported Python 2.6, it is still possible from +a SaltMaster with Python 3.5 or newer to access it. This feature requires an additional +configuration in /etc/salt/master as follows: + + +.. code-block:: yaml + + ssh_ext_alternatives: + 2016.3: # Namespace, can be actually anything. + py-version: [2, 6] # Constraint to specific interpreter version + path: /opt/2016.3/salt # Main Salt installation + dependencies: # List of dependencies and their installation paths + jinja2: /opt/jinja2 + yaml: /opt/yaml + tornado: /opt/tornado + msgpack: /opt/msgpack + certifi: /opt/certifi + singledispatch: /opt/singledispatch.py + singledispatch_helpers: /opt/singledispatch_helpers.py + markupsafe: /opt/markupsafe + backports_abc: /opt/backports_abc.py + +It is also possible to use several alternative versions of Salt. You can for instance generate +a minimal tarball using runners and include that. But this is only possible, when such specific +Salt version is also available on the Master machine, although does not need to be directly +installed together with the older Python interpreter. diff --git a/salt/client/ssh/__init__.py b/salt/client/ssh/__init__.py index f1c1ad9a22..399facf5c8 100644 --- a/salt/client/ssh/__init__.py +++ b/salt/client/ssh/__init__.py @@ -150,14 +150,10 @@ EX_PYTHON_INVALID={EX_THIN_PYTHON_INVALID} PYTHON_CMDS="python3 python27 python2.7 python26 python2.6 python2 python" for py_cmd in $PYTHON_CMDS do - if command -v "$py_cmd" >/dev/null 2>&1 && "$py_cmd" -c \ - "import sys; sys.exit(not (sys.version_info >= (2, 6) - and sys.version_info[0] == {{HOST_PY_MAJOR}}));" + if command -v "$py_cmd" >/dev/null 2>&1 && "$py_cmd" -c "import sys; sys.exit(not (sys.version_info >= (2, 6)));" then - py_cmd_path=`"$py_cmd" -c \ - 'from __future__ import print_function; - import sys; print(sys.executable);'` - cmdpath=$(command -v $py_cmd 2>/dev/null || which $py_cmd 2>/dev/null) + py_cmd_path=`"$py_cmd" -c 'from __future__ import print_function;import sys; print(sys.executable);'` + cmdpath=`command -v $py_cmd 2>/dev/null || which $py_cmd 2>/dev/null` if file $cmdpath | grep "shell script" > /dev/null then ex_vars="'PATH', 'LD_LIBRARY_PATH', 'MANPATH', \ @@ -323,7 +319,8 @@ class SSH(object): extra_mods=self.opts.get('thin_extra_mods'), overwrite=self.opts['regen_thin'], python2_bin=self.opts['python2_bin'], - python3_bin=self.opts['python3_bin']) + python3_bin=self.opts['python3_bin'], + extended_cfg=self.opts.get('ssh_ext_alternatives')) self.mods = mod_data(self.fsclient) def _get_roster(self): @@ -834,10 +831,10 @@ class Single(object): self.opts = opts self.tty = tty - if kwargs.get('wipe'): - self.wipe = 'False' + if kwargs.get('disable_wipe'): + self.wipe = False else: - self.wipe = 'True' if self.opts.get('ssh_wipe') else 'False' + self.wipe = bool(self.opts.get('ssh_wipe')) if kwargs.get('thin_dir'): self.thin_dir = kwargs['thin_dir'] elif self.winrm: @@ -1161,38 +1158,39 @@ class Single(object): cachedir = self.opts['_caller_cachedir'] else: cachedir = self.opts['cachedir'] - thin_sum = salt.utils.thin.thin_sum(cachedir, 'sha1') + thin_code_digest, thin_sum = salt.utils.thin.thin_sum(cachedir, 'sha1') debug = '' if not self.opts.get('log_level'): self.opts['log_level'] = 'info' if salt.log.LOG_LEVELS['debug'] >= salt.log.LOG_LEVELS[self.opts.get('log_level', 'info')]: debug = '1' arg_str = ''' -OPTIONS = OBJ() OPTIONS.config = \ """ -{0} +{config} """ -OPTIONS.delimiter = '{1}' -OPTIONS.saltdir = '{2}' -OPTIONS.checksum = '{3}' -OPTIONS.hashfunc = '{4}' -OPTIONS.version = '{5}' -OPTIONS.ext_mods = '{6}' -OPTIONS.wipe = {7} -OPTIONS.tty = {8} -OPTIONS.cmd_umask = {9} -ARGS = {10}\n'''.format(self.minion_config, - RSTR, - self.thin_dir, - thin_sum, - 'sha1', - salt.version.__version__, - self.mods.get('version', ''), - self.wipe, - self.tty, - self.cmd_umask, - self.argv) +OPTIONS.delimiter = '{delimeter}' +OPTIONS.saltdir = '{saltdir}' +OPTIONS.checksum = '{checksum}' +OPTIONS.hashfunc = '{hashfunc}' +OPTIONS.version = '{version}' +OPTIONS.ext_mods = '{ext_mods}' +OPTIONS.wipe = {wipe} +OPTIONS.tty = {tty} +OPTIONS.cmd_umask = {cmd_umask} +OPTIONS.code_checksum = {code_checksum} +ARGS = {arguments}\n'''.format(config=self.minion_config, + delimeter=RSTR, + saltdir=self.thin_dir, + checksum=thin_sum, + hashfunc='sha1', + version=salt.version.__version__, + ext_mods=self.mods.get('version', ''), + wipe=self.wipe, + tty=self.tty, + cmd_umask=self.cmd_umask, + code_checksum=thin_code_digest, + arguments=self.argv) py_code = SSH_PY_SHIM.replace('#%%OPTS', arg_str) if six.PY2: py_code_enc = py_code.encode('base64') diff --git a/salt/client/ssh/ssh_py_shim.py b/salt/client/ssh/ssh_py_shim.py index e46220fc80..21d03343b9 100644 --- a/salt/client/ssh/ssh_py_shim.py +++ b/salt/client/ssh/ssh_py_shim.py @@ -16,11 +16,13 @@ import sys import os import stat import subprocess +import time THIN_ARCHIVE = 'salt-thin.tgz' EXT_ARCHIVE = 'salt-ext_mods.tgz' # Keep these in sync with salt/defaults/exitcodes.py +EX_THIN_PYTHON_INVALID = 10 EX_THIN_DEPLOY = 11 EX_THIN_CHECKSUM = 12 EX_MOD_DEPLOY = 13 @@ -28,14 +30,13 @@ EX_SCP_NOT_FOUND = 14 EX_CANTCREAT = 73 -class OBJ(object): +class OptionsContainer(object): ''' An empty class for holding instance attribute values.
