PR: Add option to prepend or append Pythonpath Manager paths to sys.path #21769

mrclary · 2024-02-06T16:35:56Z

Description of Changes

Wrote at least one-line docstrings (for any new functions)
Added unit test(s) covering the changes (if testable)
Included a screenshot or animation (if affecting the UI, see Licecap)

UI/UX Changes

Added import button to update System Paths from the system PYTHONPATH environment variable.
Added toggle button that sets whether active paths should be prepended to or appended to sys.path in IPython console and Jedi completion environments.

Primary Changes

These changes directly affect the plugin API.

Spyder's transient configuration now includes user_paths, system_paths, and prioritize. user_paths and system_paths are dictionaries with path as key and enabled state as value. prioritize is a boolean. The unofficial configuration keys path, user_path, and system_path are no longer used. The spyder_pythonpath configuration key remains unchanged.
SPY_PYTHONPATH environment variable is eliminated in favor of directly accessing the spyder_pythonpath configuration key in the pythonpath_manager configuration section on startup of IPython console kernels.
sig_pythonpath_changed now sends the new spyder_pythonpath value (list of strings) and prioritize (boolean). This signal no longer sends the "old" paths. The old paths were only required by spyder-kernels in order to remove those paths from sys.path before adding the new paths to sys.path. The update to spyder-kernels in the companion PR eliminates the need for sending the "old" paths.
Fixed an issue where changes made by the user in the UI were applied even when the user presses the cancel button, if the system paths had changed on disk.
Fixed an issue where removing all user paths and then adding a user path resulted in an UnboundLocalError.

Secondary Changes

In order to simplify the handling of PYTHONPATH, the following changes were made to the Pythonpath Manager plugin. These do not directly affect the UI, UX, or plugin API, but streamline and clarify the actions performed within the plugin.

The internal attributes of the PythonpathContainer container object and the PathManager widget object were changed from path, not_active_path, user_path, system_path, and original_path_dict, to the less ambiguous user_paths and system_paths. The latter are maintained as OrderedDict objects throughout.
The pythonpath_manager configurations are now only set in PythonpathContainer._save_paths, and only on condition of change, rather than in multiple locations throughout the container and PathManager widget.
The sig_pythonpath_changed signal is emitted only in PythonpathContainer._save_paths, and only on condition that spyder_pythonpath or prioritize has changed.

Should python-lsp-server.pylsp.Document.sys_path be removed (API break)?
What icon should be used for the prioritze button?

…_paths, system_paths) and dictionary type

…pdate_paths method and call setup in update-paths method. This will allow the container to instantiate the PathManager widget before providing paths. Paths will not be retrieved or determined within the widget, only passed to it by the container.

These will be dictionaries and the container will handle updating the pythonpath_manager configuration and assembling the final spyder_pythonpath. There is no need for _update_system_path method because the container will handle updates to the underlying system path. Again, the widget will only handle user-interactive changes.

This will be done in the container instead.

…oritize) -> (_user_paths, _system_paths, _project_paths, _prioritize, _spyder_pythonpath). Path lists are now OrderedDict * Simplifies _load_pythonpath -> _load_paths * Move migration method from setup to _load_paths

* Promptly exits if remnants of old configuration are not present * Removes remnants of old configuration if present * Constructs user paths from old configuration remnants

* Configuration keys and private attributes for user paths, system paths, prioritize, and spyder_pythonpath are set conditionally in this method and nowhere else. * sig_pythonpath_changed is conditionally emitted from this method and nowhere else. This signal now sends only the spyder_pythonpath and prioritize, not the old spyder_pythonpath. Subscribers should update accordingly.

The desired affect is project paths | user paths | system paths, where the paths are in that order and are overwritten in that order. System paths cannot overwrite user paths, which cannot overwrite project paths, i.e we cannot just do project_paths.update(user_paths) etc.

…path manager widget is invoked. If the system paths have changed since last widget invocation, then the user may not be aware and there is no indication in the widget that there has been a change. Furthermore, canceling the widget may still result in a change to the pythonpath, which would be inconsistent with the cancel action.

Rather than automatically updating the system paths, provide mechanism for user to do so.

* Test system PYTHONPATH import in test_pathmanager instead of test_mainwindow * Move restore_user_env fixture from app/tests/conftest.py to utils/tests/conftest.py * Ensure that the user environment script runs on posix while testing
