From 8987797444ec2fc6c8f920b3e46d6f12d2cbf864 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Thu, 26 Dec 2024 11:41:21 +0100 Subject: [PATCH v3 1/4] flex code modernization: Replace YY_EXTRA_TYPE define with flex option Replace #define YY_EXTRA_TYPE with %option extra-type. The latter is the way recommended by the flex manual (available since flex 2.5.34). --- src/backend/parser/scan.l | 7 +------ src/backend/replication/repl_scanner.l | 2 +- src/backend/replication/syncrep_scanner.l | 2 +- src/backend/utils/adt/jsonpath_scan.l | 2 +- src/bin/psql/psqlscanslash.l | 12 ++++++------ src/fe_utils/psqlscan.l | 12 ++++++------ 6 files changed, 16 insertions(+), 21 deletions(-) diff --git a/src/backend/parser/scan.l b/src/backend/parser/scan.l index a152cff4117..7808e1c1484 100644 --- a/src/backend/parser/scan.l +++ b/src/backend/parser/scan.l @@ -89,12 +89,6 @@ const uint16 ScanKeywordTokens[] = { */ #define YYSTYPE core_YYSTYPE -/* - * Set the type of yyextra.
