Actual

Running 651 tests using 2 workers

Error: EACCES: permission denied, open '/tmp/playwright-transform-cache/3f/connectionFailurespec_3fcb2d59d7f1ac9abe23f187eeeed5065482bbfa.map'

The permissions on /tmp/playwright-transform-cache:

drwxrwxrwx 162 BrentBaccala BrentBaccala 4096 Mar 21 23:28 /tmp/playwright-transform-cache/

BrentBaccala is one of the users on the system. Permissions on some subdirectories:

drwxrwxrwx 2 BrentBaccala    BrentBaccala    4096 Feb 21 12:04 3e
drwxr-xr-x 2 MaximKhlobystov MaximKhlobystov 4096 Mar  1 13:44 3f
drwxrwxrwx 2 BrentBaccala    BrentBaccala    4096 Feb 21 12:04 42

MaximKhlobystov is also a user on the system, and I'm running this test (that's trying to access 3f) as user baccala, so obviously there's a problem.

It looks like Maxim is also running Playwright 1.28.1.

What explanation is there for how this directory 3f was created with these restrictive permissions? It surely happened on a previous playwright run, and I really don't know what the exact test configuration was that caused this. The directory is dated March 1, and today is March 21, so reproducing exactly what caused this might be problematic (if it isn't obvious to somebody).

@BrentBaccala I skimmed through the code, and by default, Playwright creates all cache folders with drwxrwxrwx permissions.

Any chance you can come up with a repro for this situation? Maybe docker might help to reproduce this in isolation?

[mxschmitt]

I can repro.

1. create two users
2. one project
3. npx playwright test with user1 in project
4. modify test file and do n px playwright test with user2 in the same project
5. observe error

@mxschmitt, thank you! (perhaps I should have tried that)

It wasn't as hard to reproduce as I had feared.
