From 21586dfb084b05ac7d98ee990d64637b4be9222a Mon Sep 17 00:00:00 2001 From: Ingo Struewing Date: Tue, 29 Sep 2009 17:38:40 +0200 Subject: WL#4259 - Debug Sync Facility Backport from 6.0 to 5.1. Only those sync points are included, which are used in debug_sync.test. The Debug Sync Facility allows to place synchronization points in the code: open_tables(...) DEBUG_SYNC(thd, "after_open_tables"); lock_tables(...) When activated, a sync point can - Send a signal and/or - Wait for a signal Nomenclature: - signal: A value of a global variable that persists until overwritten by a new signal. The global variable can also be seen as a "signal post" or "flag mast". Then the signal is what is attached to the "signal post" or "flag mast". - send a signal: Assign the value (the signal) to the global variable ("set a flag") and broadcast a global condition to wake those waiting for a signal. - wait for a signal: Loop over waiting for the global condition until the global value matches the wait-for signal. Please find more information in the top comment in debug_sync.cc or in the worklog entry. --- CMakeLists.txt | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'CMakeLists.txt') diff --git a/CMakeLists.txt b/CMakeLists.txt index 7d91e39eb6d..8c40312e32b 100755 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -66,6 +66,12 @@ IF(EXTRA_DEBUG) ADD_DEFINITIONS(-D EXTRA_DEBUG) ENDIF(EXTRA_DEBUG) +IF(ENABLED_DEBUG_SYNC) + ADD_DEFINITIONS(-D ENABLED_DEBUG_SYNC) +ENDIF(ENABLED_DEBUG_SYNC) +SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -DENABLED_DEBUG_SYNC") +SET(CMAKE_C_FLAGS_DEBUG "${CMAKE_C_FLAGS_DEBUG} -DENABLED_DEBUG_SYNC") + # in some places we use DBUG_OFF SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -DDBUG_OFF") SET(CMAKE_CXX_FLAGS_RELWITHDEBINFO "${CMAKE_CXX_FLAGS_RELWITHDEBINFO} -DDBUG_OFF") -- cgit v1.2.1
