New submission from Terry J. Reedy: This issue continues #25507. I still want to reduce the number of modules imported when run.py starts a user process and the time they require. In the process, I expect to reduce the number of tkinter module imports that need to be reversed and thereby make parts of the #25507 fix unnecessary.
"New changeset 93d325c64104 by Terry Jan Reedy in branch 'default': Issue #25507: Move 4 objects from pyshell to run and switch inports. https://hg.python.org/cpython/rev/93d325c64104"; This commit for #25507 was not needed for the fix I eventually choose, but it reduced the size of sys.modules in the user process from 193 to 156. I have since determined that it reduced the time for startup imports on my machine from .45 to .25 seconds. I now regard it as the first patch for this issue. The attached file was explained in msg270522. This and similar refactorings should be done when or after I have otherwise revised the module and tests in question. For a Windows build of repository 3.6, importing tkinter into a fresh python process increases len(sys.modules) from 41 to 65. But run only imports tkinter so it can call _tkinter.tkapp().eval('update') in its interactive input loop. If other indirect imports were eliminated, I suspect _tkinter could be imported instead. ---------- assignee: terry.reedy components: IDLE files: run_autocomplete.diff keywords: patch messages: 270592 nosy: terry.reedy priority: normal severity: normal stage: needs patch status: open title: IDLE: Reduce number and time for user process imports type: enhancement versions: Python 3.6 Added file: http://bugs.python.org/file43759/run_autocomplete.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27534> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
