[issue30441] os.environ raises RuntimeError: dictionary changed size during iteration

Osvaldo Santana Neto added the comment: This is an alternative implementation using `threading.Lock()`. The main issue with this implementation relies on the fact that we've to import the `threading` module during CPython interpreter loading (currently it's not imported by default). This is c

[issue30465] FormattedValue expressions have wrong lineno and col_offset information

New submission from Łukasz Langa: f-strings are computed in a separate compiler step. This makes their lineno and col_offset information wrong. This is problematic for flake8 which reports problems inside f-strings on the wrong line (typically the first one). Attached patch fixes the issue. -

Eryk Sun added the comment: It might be simplest to close this as 3rd party since it's similar to bpo-29817. A workaround is to call f.seek(0, 1) to reset the stream state when switching between reading and writing. That said, a switch to writing at EOF should be supported. The problem is tha
