Regexes in difflib and poplib were vulnerable to catastrophic backtracking.
|
|
These regexes formed potential DOS vectors (REDOS). They have been

refactored. This resolves CVE-2018-1060 and CVE-2018-1061. Patch by Jamie

|

|
|
Set ``__file__`` while running a startup file. Like Python, IDLE optionally
|
|
runs one startup file in the Shell window before presenting the first
|
|
interactive input prompt. For IDLE, ``-s`` runs a file named in
|
|
environmental variable :envvar:`IDLESTARTUP` or :envvar:`PYTHONSTARTUP`;
|
|
``-r file`` runs ``file``. Python sets ``__file__`` to the startup file
|
|
name before running the file and unsets it before the first prompt. IDLE
|
|
now does the same when run normally, without the ``-n`` option.

test_file_buttons() only looks at initial ascii-only lines, but failed on

and decodes far enough ahead to encounter a non-ascii character in
