From 865685dc0c0d7dec7415b82bf93ad63ca26cbacc Mon Sep 17 00:00:00 2001 From: Michael Widenius Date: Tue, 21 Dec 2010 19:22:20 +0200 Subject: [PATCH] Fixed bug in Aria that caused REPAIR to find old deleted rows. BUILD/compile-pentium64: Added --with-zlib-dir=bundled when doing static build. mysql-test/suite/maria/r/maria.result: Added test case mysql-test/suite/maria/t/maria.test: Added test case storage/maria/ma_blockrec.c: We need to flush blob pages to disk to ensure they overwrite any reused head/tail pages. If not, REPAIR will find rows that was previously deleted. --- BUILD/compile-pentium64 | 5 ++++- mysql-test/suite/maria/r/maria.result | 16 ++++++++++++++++ mysql-test/suite/maria/t/maria.test | 18 ++++++++++++++++++ storage/maria/ma_blockrec.c | 2 +- 4 files changed, 39 insertions(+), 2 deletions(-) diff --git a/BUILD/compile-pentium64 b/BUILD/compile-pentium64 index 3a8fad51fea..01eb2adf88b 100755 --- a/BUILD/compile-pentium64 +++ b/BUILD/compile-pentium64 @@ -4,7 +4,10 @@ path=`dirname $0` .
