dmypy does not work right with disable_error_code/enable_error_code

Bug Report

dmypy doesn't support disable_error_code and enable_error_code key in pyproject.toml/mypy.ini?

in pyproject.toml:

# pyproject.toml
[tool.mypy]
disable_error_code = ['var-annotated']

run: dmypy run a.py
output: Timed out waiting for daemon to start

But when disable_error_code = [] or doesn't has disable_error_code, dmypy work right.

Your Environment

• Mypy version used: 0.981, 0.991
• Mypy command-line flags: dmypy run a/a.py
• Mypy configuration options from pyproject.toml: disable_error_code = ['var-annotated']
• Python version used: 3.11

Hm, I cannot reproduce this, I get

(mypy_dev_3_11) ivan@x333:~/src/random_tests/tstconf$ dmypy run a.py
Daemon started
Success: no issues found in 44 source files
(mypy_dev_3_11) ivan@x333:~/src/random_tests/tstconf$ cat pyproject.toml 
[tool.mypy]
disable_error_code = ['var-annotated']

(mypy_dev_3_11) ivan@x333:~/src/random_tests/tstconf$ cat a.py
x = []
(mypy_dev_3_11) ivan@x333:~/src/random_tests/tstconf$ dmypy --version
dmypy 0.991

Btw you can try using --log-file FILE to debug this. Daemon may log something useful there. Also btw are you on Windows?

after I run dmypy run a.py --log-file log.txt, I get Timed out waiting for daemon to start and no file create.

[uf-fipper]

I run the command on win11

[ilevkivskyi]

For something Windows-specific @ethanhs can help.

I could reproduce this on Windows, but when I try multiple times it does not happen again, I wonder if this is a non-deterministic bug...

I'll try to dig into more this weekend.
