This is used by<br>astobj2.c to eliminate storage for tracking fields when DEBUG_THREADS is<br>not defined.<br><br>Change-Id: Iabd650908901843e9fff47ef1c539f0e1b8cb13b<br>---<br>M include/asterisk/astobj2.h<br>M include/asterisk/lock.h<br>M main/astobj2.c<br>M main/lock.c<br>4 files changed, 81 insertions(+), 90 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/17/10317/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/include/asterisk/astobj2.h b/include/asterisk/astobj2.h</span><br><span>index 0e442db..8e3a105 100644</span><br><span>--- a/include/asterisk/astobj2.h</span><br><span>+++ b/include/asterisk/astobj2.h</span><br><span>@@ -752,6 +752,9 @@</span><br><span> * lock address, this allows you to correlate against</span><br><span> * object address, to match objects to reported locks.</span><br><span> *</span><br><span style="color: hsl(120, 100%, 40%);">+ * \warning AO2 lock objects do not include tracking fields when</span><br><span style="color: hsl(120, 100%, 40%);">+ * DEBUG_THREADS is not enabled.</span><br><span style="color: hsl(120, 100%, 40%);">+ *</span><br><span> * \since 1.6.1</span><br><span> */</span><br><span> void *ao2_object_get_lockaddr(void *obj);</span><br><span>diff --git a/include/asterisk/lock.h b/include/asterisk/lock.h</span><br><span>index 5b6817f..28091f9 100644</span><br><span>--- a/include/asterisk/lock.h</span><br><span>+++ b/include/asterisk/lock.h</span><br><span>@@ -92,11 +92,11 @@</span><br><span> #define AST_LOCK_TRACK_INIT_VALUE { { NULL }, { 0 }, 0, { NULL }, { 0 }, PTHREAD_MUTEX_INIT_VALUE }</span><br><span> #endif</span><br><span> </span><br><span style="color: hsl(0, 100%, 40%);">-#define AST_MUTEX_INIT_VALUE { PTHREAD_MUTEX_INIT_VALUE, NULL, 1 }</span><br><span style="color: hsl(0, 100%, 40%);">-#define AST_MUTEX_INIT_VALUE_NOTRACKING { PTHREAD_MUTEX_INIT_VALUE, NULL, 0 }</span><br><span style="color: hsl(120, 100%, 40%);">+#define AST_MUTEX_INIT_VALUE { PTHREAD_MUTEX_INIT_VALUE, NULL, {1, 0} }</span><br><span style="color: hsl(120, 100%, 40%);">+#define AST_MUTEX_INIT_VALUE_NOTRACKING { PTHREAD_MUTEX_INIT_VALUE, NULL, {0, 0} }</span><br><span> </span><br><span style="color: hsl(0, 100%, 40%);">-#define AST_RWLOCK_INIT_VALUE { __AST_RWLOCK_INIT_VALUE, NULL, 1 }</span><br><span style="color: hsl(0, 100%, 40%);">-#define AST_RWLOCK_INIT_VALUE_NOTRACKING { __AST_RWLOCK_INIT_VALUE, NULL, 0 }</span><br><span style="color: hsl(120, 100%, 40%);">+#define AST_RWLOCK_INIT_VALUE { __AST_RWLOCK_INIT_VALUE, NULL, {1, 0} }</span><br><span style="color: hsl(120, 100%, 40%);">+#define AST_RWLOCK_INIT_VALUE_NOTRACKING { __AST_RWLOCK_INIT_VALUE, NULL, {0, 0} }</span><br><span> </span><br><span> #define AST_MAX_REENTRANCY 10</span><br><span> </span><br><span>@@ -120,6 +120,13 @@</span><br><span> pthread_mutex_t reentr_mutex;</span><br><span> };</span><br><span> </span><br><span style="color: hsl(120, 100%, 40%);">+struct ast_lock_track_flags {</span><br><span style="color: hsl(120, 100%, 40%);">+ /*! non-zero if lock tracking is enabled */</span><br><span style="color: hsl(120, 100%, 40%);">+ unsigned int tracking:1;</span><br><span style="color: hsl(120, 100%, 40%);">+ /*! non-zero if track is setup */</span><br><span style="color: hsl(120, 100%, 40%);">+ volatile unsigned int setup:1;</span><br><span style="color: hsl(120, 100%, 40%);">+};</span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span> /*! \brief Structure for mutex and tracking information.</span><br><span> *</span><br><span> * We have tracking information in this structure regardless of DEBUG_THREADS being enabled.</span><br><span>@@ -127,9 +134,18 @@</span><br><span> */</span><br><span> struct ast_mutex_info {</span><br><span> pthread_mutex_t mutex;</span><br><span style="color: hsl(0, 100%, 40%);">- /*!
