Fix: perform macro expansion on tracepoint signatures
The problem can be seen by patching the demo test from lttng-ust as
follows:
--- a/tests/demo/ust_tests_demo3.h
+++ b/tests/demo/ust_tests_demo3.h
@@ -22,12 +22,14 @@ extern "C" {
* all copies or substantial portions of the Software.
*/
+#include <stdbool.h>
+
#include <lttng/tracepoint.h>
TRACEPOINT_EVENT(ust_tests_demo3, done,
- TP_ARGS(int, value),
+ TP_ARGS(bool, value),
TP_FIELDS(
- ctf_integer(int, value, value)
+ ctf_integer(bool, value, value)
)
)
Then when the demo is run with LTTNG_UST_DEBUG=1, a warning is shown,
like:
liblttng_ust_tracepoint[3315/3315]: Warning: Tracepoint signature mismatch, not
enabling one or more tracepoints. Ensure that the tracepoint probes prototypes
match the application. (in set_tracepoint() at tracepoint.c:310)
liblttng_ust_tracepoint[3315/3315]: Warning: Tracepoint "ust_tests_demo3:done"
signatures: call: "_Bool, value" vs probe: "bool, value". (in set_tracepoint()
at tracepoint.c:312)
It seems that TP_ARGS does not perform preprocessor expansion on the
"bool" type spec, while something underneath TP_FIELDS does. And since
(at least on this Centos 6.2 box) stdbool.h uses a #define rather than a
typedef to make bool equivalent to _Bool, liblttng detects a mismatch.

Fix: fix deadlock with dlopen() lttng-ust
Pre-"fault" the libuuid TLS outside of the ust lock to ensure that we
never deadlock with the linker mutex in libc. This mutex is held both
for TLS fixup of dlopen'd libs, and across execution of all
constructors. We therefore have a reverse use of this mutex wrt ust
lock, that we fix by forcing the TLS fixup to happen very early in the
lttng-ust constructor.

Never spam the console, even in debug mode, since it would make debug
