Selector for classes and functions not working when file is part of a project

[yves-surrel]

Spyder 5.0, MacOs 11.2.1

Problem Description

The selector for classes and functions dropdown remain empty when the file is part of a project

What steps reproduce the problem?

1. Edit a file that is not part of a project, from the file>Open menu. The dropdowns are filled OK.
2. Make a project from the directory where the file is. Open the file by double-clicking on the project pane treeview. The dropdown remain empty.

I create a new issue since #13131 has been closed, and my title is more descriptive.

Hi @yves-surrel,

Can you please update to the latest version of Spyder 5.0.2 via conda-forge or one of our installers and see if the error is still happening? Also, can you recall when was the previous version where this wasn't an issue?

Hi Stephannie
No change with Spyder 5.0.2.
However, my own investigations lead to an important information. The problem is only indirectly related to project creation. It seems to be more related to the PYTHONPATH content. When a project is created, a PYTHONPATH entry is created, as seen in the PYTHONPATH manager. When the project is deleted, the entry is automatically removed.

If I manually add an entry in the PYTHONPATH manager, the problem arises, but not always. In my case, although I do not know if it is a general rule, adding the parent or grandparent directory of the open file rises the problem.

I checked that the result param in DocumentProvider.process_document_symbol_request (spyder/plugins/completion/providers/languageserver/providers/document.py) returned different contents with and without an entry in PYTHONPATH. AFAIU it may be related to filling the symbols from the document, but I could not figure out where this is done (something to do with 'Langage Server Protocol' that I know nothing about).

In spyder/plugins/completion/providers/languageserver/providers/workspace.py, I made the following change:

class WorkspaceProvider:
    @send_notification(method=CompletionRequestTypes.WORKSPACE_CONFIGURATION_CHANGE)
    def send_configurations(self, configurations, *args):
        self.configurations = configurations
        params = {
            'settings': configurations
        }
        # ******** Added ************
        params['settings']['pyls']['plugins']['jedi']['extra_paths'] = []
        # ****************************
        return params

that removes what is added by changing the PYTHONPATH manually.

This fixes the problem when adding a path manually in the PYTHONPATH manager, however there is still the problem when creating a project (in all my trials, my test file is within the created project).

Hey @yves-surrel, thanks a lot for digging into this! That's really helpful.

This information will allow us to better debug and finally solve this problem.

[yves-surrel]

Feel free to ask for any other test ;-)

This may be related, but I've also noticed that the class and function selector is empty for second editor panes.

@yves-surrel, the OP issue may already be resolved; I cannot reproduce from bootstrap using the latest commit (d22f459). However, there are a couple of visible issues unrelated to the OP:

• When creating a new project, the previously open file is closed and temp.py is opened. This is a result of closing open files when a project is opened, but the opened project doesn't have project files designated yet, so it defaults to temp.py
• For conda bootstrapping, opening (or switching) a project can sometimes cause a traitlets kernel to die, causing a long delay for the console to restart.

Still not working in Spyder 5.0.5

We're working to fix this problem in our next version (5.1.0), to be released at the end of the month.
