Bugfix: crashes when OPTIONS.saltdir is a file salt-ssh: allow server and client to run different python major version Handle non-directory on the /tmp Bugfix: prevent partial fileset removal in /tmp salt-ssh: compare checksums to detect newly generated thin on the server Reset time at thin unpack Bugfix: get a proper option for CLI and opts of wiping the tmp Add docstring to get_tops Remove unnecessary noise in imports Refactor get_tops collector Add logging to the get_tops Update call script Remove pre-caution Update log debug message for tops collector Reset default compression, if unknown is passed Refactor archive creation flow Add external shell-callable function to collect tops Simplify tops gathering, bugfix alternative to Py2 find working executable Add basic shareable module classifier Add proper error handler, unmuting exceptions during top collection Use common shared directory for compatible libraries fix searching for python versions Flatten error message string Bail-out immediately if <2.6 version detected Simplify shell cmd to get the version on Python 2.x Remove stub that was previously moved upfront Lintfix: PEP8 ident Add logging on the error, when Python-2 version cannot be detected properly Generate salt-call source, based on conditions Add logging on remove failure on thin.tgz archive Add config-based external tops gatherer Change signature to pass the extended configuration to the thin generator Update docstring to the salt-call generator Implement get namespaces inclusion to the salt-call script on the client machine Use new signature of the get call Implement namespace selector, based on the current Python interpreter version Add deps as a list, instead of a map Add debug logging Implement packaging an alternative version Update salt-call script so it swaps the namespace according to the configuration Compress thin.zip if zlib is available Fix a system exit error message Move compression fall-back operation Add debug logging prior to the thin archive removal Flatten the archive extension choice Lintfix: PEP8 an empty line required Bugfix: ZFS modules (zfs, zpool) crashes on non-ZFS systems Add unit test case for the Salt SSH parts Add unit test for missing dependencies on get_ext_tops Postpone inheritance implementation Refactor unit test for get_ext_tops Add unit test for get_ext_tops checks interpreter configuration Check python interpreter lock version Add unit test for get_ext_tops checks the python locked interepreter value Bugfix: report into warning log module name, not its config Add unit test for dependencies check python version lock (inherently) Mock os.path.isfile function Update warning logging information Add unit test for get_ext_tops module configuration validation Do not use list of dicts for namespaces, just dict for namespaces. Add unit test for get_ext_tops config verification Fix unit tests for the new config structure Add unit test for thin.gte call Add unit test for dependency path adding function Add unit test for thin_path function Add unit test for salt-call source generator Add unit test for get_ext_namespaces on empty configuration Add get_ext_namespaces for namespace extractions into a tuple for python version Remove unused variable Add unit test for getting namespace failure when python maj/min versions are not defined Add unit test to add tops based on the current interpreter Add unit test for get_tops with extra modules Add unit test for shared object modules top addition Add unit test for thin_sum hashing Add unit test for min_sum hashing Add unit test for gen_thin verify for 2.6 Python version is a minimum requirement Fix gen_thin exception on Python 3 Use object attribute instead of indeces. Remove an empty line. Add unit test for gen_thin compression type fallback Move helper functions up by the class code Update unit test doc Add check for correct archiving mode is opened Add unit test for gen_thin if control files are written correctly Update docstring for fake version info constructor method Add fake tarfile mock handler Mock-out missing methods inside gen_thin Move tarfile.open check to the end of the test Add unit test for tree addition to the archive Add shareable module to the gen_thin unit test Fix docstring Add unit test for an alternative version pack Lintfix Add documentation about updated Salt SSH features Fix typo Lintfix: PEP8 extra-line needed Make the command more readable Write all supported minimal python versions into a config file on the target machine Get supported Python executable based on the config py-map Add unit test for get_supported_py_config function typecheck Add unit test for get_supported_py_config function base tops Add unit test for get_supported_py_config function ext tops Fix unit test for catching "supported-versions" was written down Rephrase Salt SSH doc description Re-phrase docstring for alternative Salt installation require same major version while minor is allowed to be higher Bugfix: remove minor version from the namespaced, version-specific directory Fix unit tests for minor version removal of namespaced version-specific directory Initialise the options directly to be structure-ready object. Disable wiping if state is executed Properly mock a tempfile object Support Python 2.6 versions Add digest collector for file trees etc Bufix: recurse calls damages the configuration (reference problem) Collect digest of the code Get code checksum into the shim options Get all the code content, not just Python sources Bugfix: Python3 compat - string required instead of bytes Lintfix: too many empty lines Lintfix: blocked function used Bugfix: key error master_tops_first Fix unit tests for the checksum generator Use code checksum to update thin archive on client's cache Lintfix Set master_top_first to False by default --- doc/topics/releases/fluorine.rst | 178 +++++++++++++++++++++++++++++++ salt/client/ssh/ssh_py_shim.py | 4 + salt/utils/thin.py | 1 + 3 files changed, 183 insertions(+) create mode 100644 doc/topics/releases/fluorine.rst diff --git a/doc/topics/releases/fluorine.rst b/doc/topics/releases/fluorine.rst new file mode 100644 index 0000000000..40c69e25cc --- /dev/null +++ b/doc/topics/releases/fluorine.rst @@ -0,0 +1,178 @@ +:orphan: + +====================================== +Salt Release Notes - Codename Fluorine +====================================== + + +Minion Startup Events +--------------------- + +When a minion starts up it sends a notification on the event bus with a tag +that looks like this: `salt/minion/<minion_id>/start`. For historical reasons +the minion also sends a similar event with an event tag like this: +`minion_start`. This duplication can cause a lot of clutter on the event bus +when there are many minions. Set `enable_legacy_startup_events: False` in the +minion config to ensure only the `salt/minion/<minion_id>/start` events are +sent. + +The new :conf_minion:`enable_legacy_startup_events` minion config option +defaults to ``True``, but will be set to default to ``False`` beginning with +the Neon release of Salt. + +The Salt Syndic currently sends an old style `syndic_start` event as well.

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/ssh_py_shim.py b/salt/client/ssh/ssh_py_shim.py index be17a1a38c..595d1c40c7 100644 --- a/salt/client/ssh/ssh_py_shim.py +++ b/salt/client/ssh/ssh_py_shim.py @@ -164,6 +164,9 @@ def unpack_thin(thin_path): old_umask = os.umask(0o077) # pylint: disable=blacklisted-function tfile.extractall(path=OPTIONS.saltdir) tfile.close() + checksum_path = os.path.normpath(os.path.join(OPTIONS.saltdir, "thin_checksum")) + with open(checksum_path, 'w') as chk: + chk.write(OPTIONS.checksum + '\n') os.umask(old_umask) # pylint: disable=blacklisted-function try: os.unlink(thin_path) @@ -357,5 +360,6 @@ def main(argv): # pylint: disable=W0613 return retcode + if __name__ == '__main__': sys.exit(main(sys.argv)) diff --git a/salt/utils/thin.py b/salt/utils/thin.py index b60815225e..172b0938f5 100644 --- a/salt/utils/thin.py +++ b/salt/utils/thin.py @@ -9,6 +9,7 @@ from __future__ import absolute_import, print_function, unicode_literals import copy import logging import os +import copy import shutil import subprocess import sys -- 2.17.1
