From f78319fec8eb8aed34d6e1e43ca35fb0a9bfe108 Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Wed, 1 Oct 2014 11:54:05 +0200 Subject: Rename CACHE_LINE_SIZE to PG_CACHE_LINE_SIZE. As noted in http://bugs.debian.org/763098 there is a conflict between postgres' definition of CACHE_LINE_SIZE and the definition by various *bsd platforms. It's debatable who has the right to define such a name, but postgres' use was only introduced in 375d8526f290 (9.4), so it seems like a good idea to rename it. Discussion: 20140930195756.GC27407@msg.df7cb.de Per complaint of Christoph Berg in the above email, although he's not the original bug reporter. Backpatch to 9.4 where the define was introduced. --- src/backend/access/transam/xlog.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/backend/access/transam/xlog.c') diff --git a/src/backend/access/transam/xlog.c b/src/backend/access/transam/xlog.c index 7eea5fabaf5..9b938bda740 100644 --- a/src/backend/access/transam/xlog.c +++ b/src/backend/access/transam/xlog.c @@ -408,7 +408,7 @@ typedef struct typedef union WALInsertLockPadded { WALInsertLock l; - char pad[CACHE_LINE_SIZE]; + char pad[PG_CACHE_LINE_SIZE]; } WALInsertLockPadded; /* @@ -435,7 +435,7 @@ typedef struct XLogCtlInsert * read on every WAL insertion, but updated rarely, and we don't want * those reads to steal the cache line containing Curr/PrevBytePos. */ - char pad[CACHE_LINE_SIZE]; + char pad[PG_CACHE_LINE_SIZE]; /* * fullPageWrites is the master copy used by all backends to determine -- cgit v1.2.3
