Subject: [PATCH] patch 9.2.0568: pythoncomplete: g:pythoncomplete_allow_import
|
|
had no effect
|
|
|
|
Problem: The security patch 9.2.0561 added a vim.eval() call inside
|
|
Completer.evalsource() to honor g:pythoncomplete_allow_import.
|
|
But the 'vim' module is only imported inside the outer
|
|
vimcomplete() / vimpy3complete() function, not at the script's
|
|
top level, so referring to it from a Completer method raises
|
|
NameError. The surrounding bare 'except' silently swallows
|
|
the error and leaves allow_imports at 0, meaning the opt-in
|
|
never takes effect -- 'import os' (and any other
|
|
buffer-level import) is always skipped, no candidates are
|
|
produced for 'os.<...>' and
|
|
Test_popup_and_preview_autocommand() fails on the Windows
|
|
CI matrix (Linux skips the test because Python 2 is absent).
|
|
Solution: Re-import 'vim' at the top of evalsource() in both
|
|
pythoncomplete.vim and python3complete.vim so the eval reads
|
|
the global, and set g:pythoncomplete_allow_import = 1 in the
|
|
test (it is the opt-in intended for callers that trust the
|
|
buffer contents) (thinca).
|
|
|
|
closes: #20386
