Changes description

This is a preparation PR to enable snow ws deploy for application package entities in the following PR. The end goal is to reuse the same logic in both NativeAppManager.deploy() and ApplicationPackageEntity/ApplicationEntity actions.

Extracted methods

The first step is to extract the minimal logic out of NativeAppManager to enable ApplicationPackageEntity.action_deploy() (which will be very similar to NativeAppManager.deploy()). The following methods were moved from NativeAppManager and modified to be stateless:

ApplicationPackageEntity

• get_existing_app_pkg_info()
• get_app_pkg_distribution_in_snowflake()
• verify_project_distribution()
• use_package_warehouse()
• apply_package_scripts()
• create_app_package()

utils

• generic_sql_error_handler()
• ensure_correct_owner()
• sync_deploy_root_with_stage()
• _get_stage_paths_to_sync()
• execute_post_deploy_hooks()
• _execute_sql_script()
• expand_script_templates()

Even though they are now just proxies, the methods in NativeAppManager were kept with the same signatures in order to not break the interface of the class, as other flows call them and were not refactored yet (teardown, version, etc).

SqlExecutor

Added the SqlExecutor utility class to be able to execute SQL without having to inherit directly from SqlExecutionMixin.

Manual tests

snow app deploy
snow app version create v1
snow app version list
snow app version drop v1
snow app teardown
snow app run
