From 4d3810b62dd11d19719adfa0f667b44fabff4d00 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Thu, 5 Oct 2023 21:31:58 +0200 Subject: [PATCH] gh-110429: Fix race condition in "make regen-all" "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. --- Makefile.pre.in | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Makefile.pre.in b/Makefile.pre.in index 97eb767b8fcdeb..f1f5c8557e7ffc 100644 --- a/Makefile.pre.in +++ b/Makefile.pre.in @@ -1399,8 +1399,8 @@ regen-pegen: PYTHONPATH=$(srcdir)/Tools/peg_generator $(PYTHON_FOR_REGEN) -m pegen -q c \ $(srcdir)/Grammar/python.gram \ $(srcdir)/Grammar/Tokens \ - -o $(srcdir)/Parser/parser.new.c - $(UPDATE_FILE) $(srcdir)/Parser/parser.c $(srcdir)/Parser/parser.new.c + -o $(srcdir)/Parser/parser.c.new + $(UPDATE_FILE) $(srcdir)/Parser/parser.c $(srcdir)/Parser/parser.c.new .PHONY: regen-ast regen-ast:
