From 9fba801c1e1e6136808dca80ccd7524ed483250e Mon Sep 17 00:00:00 2001 From: Bo Maryniuk <bo@suse.de> Date: Fri, 19 Oct 2018 15:44:47 +0200 Subject: [PATCH] Add supportconfig module for remote calls and SaltSSH Add log collector for remote purposes Implement default archive name Fix imports Implement runner function Remove targets data collector function as it is now called by a module instead Add external method decorator marker Add utility class for detecting exportable methods Mark run method as an external function Implement function setter Fix imports Setup config from __opts__ Use utility class Remove utils class Allow specify profile from the API parameter directly Rename module by virtual name Bypass parent subclass Implement profiles listing (local only for now) Specify profile from the state/call Set default or personalised archive name Add archives lister Add personalised name element to the archive name Use proper args/kwargs to the exported function Add archives deletion function Change log level when debugging rendered profiles Add ability to directly pass profile source when taking local data Add pillar profile support Remove extra-line Fix header Change output format for deleting archives Refactor logger output format Add time/milliseconds to each log notification Fix imports Switch output destination by context Add last archive function Lintfix Return consistent type Change output format for deleted archives report Implement report archive syncing to the reporting node Send multiple files at once via rsync, instead of send one after another Add sync stats formatter Change signature: cleanup -> move. Update docstring. Flush empty data from the output format Report archfiles activity Refactor imports Do not remove retcode if it is EX_OK Do not raise rsync error for undefined archives. Update header Add salt-support state module Move all functions into a callable class object Support __call__ function in state and command modules as default entrance that does not need to be specified in SLS state syntax Access from the outside only allowed class methods Pre-create destination of the archive, preventing single archive copied as a group name Handle functions exceptions Add unit test scaffold Add LogCollector UT for testing regular message Add LogCollector UT for testing INFO message Add LogCollector UT for testing WARNING message Replace hardcoded variables with defined constants Add LogCollector UT for testing ERROR message Test title attribute in msg method of LogCollector Add UT for LogCollector on highlighter method Add UT for LogCollector on put method Fix docstrings Add UT for archive name generator Add UT for custom archive name Fix docstring for the UT Add UT for checking profiles list format Add Unit Test for existing archives listing Add UT for the last archive function Create instance of the support class Add UT for successfully deleting all archives Add UT for deleting archives with failures Add UI for formatting sync stats and order preservation Add UT for testing sync failure when no archives has been specified Add UT for last picked archive has not found Add UT for last specified archive was not found Bugfix: do not create an array with None element in it Fix UT for found bugfix Add UT for syncing no archives failure Add UT for sync function Add UT for run support function Fix docstring for function "run" lintfix: use 'salt.support.mock' and 'patch()' Rewrite subdirectory creation and do not rely on Python3-only code Lintfix: remove unused imports Lintfix: regexp strings Break-down oneliner if/else clause Use ordered dictionary to preserve order of the state. This has transparent effect to the current process: OrderedDict is the same as just Python dict, except it is preserving order of the state chunks. Refactor state processing class. Add __call__ function to process single-id syntax Add backward-compatibility with default SLS syntax (id-per-call) Lintfix: E1120 no value in argument 'name' for class constructor Remove unused import Check last function by full name --- doc/ref/modules/all/index.rst | 1 + doc/ref/states/all/index.rst | 1 + salt/cli/support/__init__.py | 2 +- salt/cli/support/collector.py | 14 +- salt/loader.py | 6 +- salt/modules/saltsupport.py | 405 ++++++++++++++++++++ salt/state.py | 38 +- salt/states/saltsupport.py | 225 +++++++++++ salt/utils/args.py | 23 +- salt/utils/decorators/__init__.py | 68 ++-- tests/unit/modules/test_saltsupport.py | 496 +++++++++++++++++++++++++ 11 files changed, 1220 insertions(+), 59 deletions(-) create mode 100644 salt/modules/saltsupport.py create mode 100644 salt/states/saltsupport.py create mode 100644 tests/unit/modules/test_saltsupport.py diff --git a/doc/ref/modules/all/index.rst b/doc/ref/modules/all/index.rst index 4c93972276..9fea7af07f 100644 --- a/doc/ref/modules/all/index.rst +++ b/doc/ref/modules/all/index.rst @@ -415,6 +415,7 @@ execution modules salt_version saltcheck saltcloudmod + saltsupport saltutil schedule scp_mod diff --git a/doc/ref/states/all/index.rst b/doc/ref/states/all/index.rst index 2664b4ce45..052efe4582 100644 --- a/doc/ref/states/all/index.rst +++ b/doc/ref/states/all/index.rst @@ -281,6 +281,7 @@ state modules rvm salt_proxy saltmod + saltsupport saltutil schedule selinux diff --git a/salt/cli/support/__init__.py b/salt/cli/support/__init__.py index 4fdf44186f..59c2609e07 100644 --- a/salt/cli/support/__init__.py +++ b/salt/cli/support/__init__.py @@ -47,7 +47,7 @@ def get_profile(profile, caller, runner): if os.path.exists(profile_path): try: rendered_template = _render_profile(profile_path, caller, runner) -
