From 5a4e821b436710bc9814513965ec9ad097c4adac Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Thu, 5 Oct 2023 13:54:47 -0700 Subject: [3.12] gh-110429: Fix race condition in "make regen-all" (GH-110433) (#110438) gh-110429: Fix race condition in "make regen-all" (GH-110433) "make regen-pegen" now creates a temporary file called "parser.c.new" instead of "parser.new.c". Previously, if "make clinic" was run in parallel with "make regen-all", clinic may try but fail to open "parser.new.c" if the temporay file was removed in the meanwhile.
