"Check Project" Only Scans One File

[grvhi]

Step 1: Are you in the right place?

• I have verified there are no duplicate active or recent bugs, questions, or requests
• I have verified that I am using the latest version of the plugin.

Step 2: Describe your environment

• Plugin version: 0.7.0
• PyCharm/IDEA version: PyCharm 2018.2.2
• Mypy version: mypy 0.620

Step 3: Describe the problem:

Steps to reproduce:

1. Click "Check Project"

Observed Results:

• The scan runs, but only one file - which happens to be the first python file in the project's first module - is scanned.
• Clicking "Check Current File" results in the currently active python file (which is not the same file as that which is scanned when clicking "Check Project") being scanned as expected.

Expected Results:

• I expected that the scan would run against all python files - recursively - in all modules underneath the project root, as defined in PyCharm's Project Structure settings

Hi @grvhi, thank you for reporting this issue.
Which violations are you getting as result of the scan? Can you please post a screenshot?
Are you getting some error inside the Event Log? If yes could you post it here?
It would be possible to share a sample project where I can reproduce the issue?

[grvhi]

Hi @leinardi - here's a screenshot of what I see in the results panel. There are no logs entries at all in the Event Log.

I'll test the plugin on some other projects I have to see if I can work out where the problem might lie; it could well be something to do with my setup, but I'm not sure how best to start narrowing down the possible configuration options in order to reliably replicate the problem.

[grvhi]

@leinardi - perhaps you could help me by clarifying how the plugin interprets "Project" in this context? Does it use the value of Content Root in the Project Structure preferences panel?

So far, all my projects exhibit the same behaviour (only scanning one file from the project), but it seems to be random which file is scanned in each project; it is, though, always the same file when re-running a scan.

[leinardi]

The Scan Project is just getting all the non excluded python files in the entire PyCharm project folder:

mypy-pycharm/src/main/java/com/leinardi/pycharm/mypy/actions/ScanEverythingAction.java

Line 39 in 26fbd15

filesToScan = VfUtil.flattenFiles(new VirtualFile[]{project.getBaseDir()});

mypy-pycharm/src/main/java/com/leinardi/pycharm/mypy/util/VfUtil.java

Line 70 in 26fbd15

if (FileTypes.isPython(file.getFileType())

I fear that mypy is simply not outputting any more error after the first one.

Could you please do a test for me and fix all the errors you are getting reported to see if the scan will show something different?
If that doesn't bring us anywhere, in 3-4 hours I can provide you a debug build with some more log to get more detail about the scan (but if you can, please, try to the above test and let me know).

[grvhi]

Thanks @leinardi - your fear is indeed correct. Fixing that mypy warning I posted a screenshot of above, then re-running the Check Project, yields errors from a different file in the project.

[leinardi]

Yeah, it is the current behavior of mypy, some specific error just breaks the validation of all the other files.
