Crash on Startup when loading Pavlovia project (404 Project Not Found)

[frankpapenmeier]

Problem:
PsychoPy 2022.1.3 does not open .psyexp files for projects that have been pushed to Pavlovia before. I am running PsychoPy on Windows 11, but given the solution to this bug (see below), I assume that the issue should occur on all platforms.

Error Log:
This is the stacktrace from the "last_app_load.log" file when trying to open a respective psyexp file:

Traceback (most recent call last):
  File "C:\Program Files\PsychoPy\lib\site-packages\gitlab\exceptions.py", line 304, in wrapped_f
    return f(*args, **kwargs)

    server_data = self.gitlab.http_get(path, **kwargs)

    result = self.http_request(

    raise gitlab.exceptions.GitlabHttpError(
gitlab.exceptions.GitlabHttpError: 404: 404 Project Not Found

The above exception was the direct cause of the following exception:

gitlab.exceptions.GitlabGetError: 404: 404 Project Not Found

Reason:
I identified two bugs that caused the issue for me.

BUG 1:
too restrictive re.match pattern in pavlovia.py

SOLUTION FOR BUG 1:

In file: C:\Program Files\PsychoPy\Lib\site-packages\psychopy\projects\pavlovia.py

LINE 1201

REPLACE
url = re.match("https:\/\/gitlab\.pavlovia\.org\/\w*\/\w*\.git", stdout)

WITH
url = re.match("https:\/\/gitlab\.pavlovia\.org\/[\w\.]*\/[\w\.]*\.git", stdout)

REASON FOR ERROR:
My username contains a dot (frank.papenmeier), which was not covered by \w

BUG 2:
if projects.json in AppData\Roaming\psychopy3\pavlovia\ does not contain the project, getting the project info via gitlab fails, because user is not logged in, resulting in the "404 Project Not Found" error message

SOLUTION FOR BUG 2:

In file: C:\Program Files\PsychoPy\Lib\site-packages\psychopy\projects\pavlovia.py

ADD AFTER LINE 1252 (and thus right before the following command "project = session.gitlab.projects.get(name)" that would otherwise fail:

                    if not session.user:
                        nameSpace = name.split('/')[0]
                        if nameSpace in knownUsers:  # Log in if user is known
                            login(nameSpace, rememberMe=True)

thus the corrected code at the respective section looks as follows:

                if nameSearch is not None:
                    name = nameSearch.group(0)
                    if not session.user:
                        nameSpace = name.split('/')[0]
                        if nameSpace in knownUsers:  # Log in if user is known
                            login(nameSpace, rememberMe=True)
                    project = session.gitlab.projects.get(name)
                    return PavloviaProject(project.id)

I took the code block for logging into Pavlovia from an older version of pavlovia.py. This version also contained multiple additional ways of looking through further known users, which I thought is not required and thus left out.

This should be fixed in 2022.1.4 (available now)
