Eric Snow	9fd87a5fe5	bpo-45020: Revert "Drop the frozen .h files from the repo." (gh-28380) ... gh-28375 broke one of the buildbots. Until I figure out why, I'm rolling the change back. https://bugs.python.org/issue45020	2021-09-15 23:27:38 -06:00
Eric Snow	a9757bf34d	bpo-45020: Drop the frozen .h files from the repo. (gh-28375) ... The main advantage is that the files will no longer show up in diffs and PRs. That means, for a PR, the number of files / lines changed will more clearly reflect the actual change. https://bugs.python.org/issue45020	2021-09-15 19:15:26 -06:00
Eric Snow	cbeb819710	bpo-45020: Freeze some of the modules imported during startup. (gh-28335) ... Doing this provides significant performance gains for runtime startup (~15% with all the imported modules frozen). We don't yet freeze all the imported modules because there are a few hiccups in the build systems we need to sort out first. (See bpo-45186 and bpo-45188.) Note that in PR GH-28320 we added a command-line flag (-X frozen_modules=[on|off]) that allows users to opt out of (or into) using frozen modules. The default is still "off" but we will change it to "on" as soon as we can do it in a way that does not cause contributors pain. https://bugs.python.org/issue45020	2021-09-15 10:19:30 -06:00
