thread sanitizer warnings
Hello,
with -fsanitize=thread, I get the following warning from remotery code.
Looking at this discussion, it seems that volatileis not enough to guarantee a safe read in static rmtU32 LoadAcquire(rmtU32* volatile address). A mutex may be required... I'm not sure about which one to use so I cannot provide a quick fix, if ever it would be a fix.
Best,
Stéphane

btw, to prevent another warning, I had to exchange some code, because ThreadProfilers_Constructor creates a thread:
// Create the thread profilers container
New_2(ThreadProfilers, rmt->threadProfilers, &rmt->timer, rmt->mq_to_rmt_thread);
if (error != RMT_ERROR_NONE)
{
return error;
}
// Set as the global instance before creating any threads that uses it for sampling itself
assert(g_Remotery == NULL);
g_Remotery = rmt;
g_RemoteryCreated = RMT_TRUE;
=>
// Set as the global instance before creating any threads that uses it for sampling itself
assert(g_Remotery == NULL);
g_Remotery = rmt;
g_RemoteryCreated = RMT_TRUE;
// Create the thread profilers container
New_2(ThreadProfilers, rmt->threadProfilers, &rmt->timer, rmt->mq_to_rmt_thread);
if (error != RMT_ERROR_NONE)
{
return error;
}
Thank you.
There is scope in the future for use of std::atomic in C++ only code. It's unfortunate that the spec chooses to encode this in library primitives but we will likely have to deal with it.
Can you tell me what that last warning was? The comment is referring to Remotery's own use of rmt_BeginCPUSample to measure itself in the thread created by:
// Create the main update thread once everything has been defined for the global remotery object
New_2(rmtThread, rmt->thread, Remotery_ThreadMain, rmt);
Hi, sorry I got caught by other concerns, I did not follow up this issue, I'm back to it.
I still have the problem with the latest Remoteryversion (though I did not use the code exchange this time). I got this now:

SUMMARY: ThreadSanitizer: data race Remotery.c:717 in LoadAcquire
It's on macOS 12.4 (21F79).
I'm not quite sure about the meaning of your question ('what that last warning was?')...
Best,
Stéphane
This looks somewhat safe, although I'm struggling to find a Mac OS primitive in C to express this: if the load of write_pos is stale it just means allocations can fail when the queue isn't releasing quickly enough. There appear to be no situations where a stale write_pos can allow you to allocate from the queue when there isn't enough memory, causing an overflow.
I have not used TSAN before: does it require use of C11 atomics to inform what's going on?
In LoadAcquire, can you try inserting a call to OSMemoryBarrier() after the call to CompilerReadFence()? This will require including <libkern/OSAtomic.h>.
This all does need a very thorough cleanup on all platforms but I am lacking the time.
I tried, but it's not better. The thing is, TSAN complains about the last line of:
static rmtU32 LoadAcquire(rmtAtomicU32* address)
{
rmtU32 value = *address;
since rmtAtomicU32 is actually typedef volatile rmtU32 rmtAtomicU32, TSAN considers it as an unprotected read, since it's not really an atomic var?
This would suggest to use an actual atomic var, such as _Atomic(rmtU32) available in C11? With the associated functions such as atomic_load?
I guess TSAN doesn't understand pre-C11 code bases. It also doesn't appear to support explicit fences, so I'll have to bring in some C11 primitives. I mean, that's no loss as I can just #ifdef things a bit. In this case it sees non-atomic access racing with the atomic access as more harmful than it actually is.
This seems like a very similar Issue: https://github.com/microsoft/mimalloc/issues/130
There are actually no fence primitives introduced for load/acquire & store/release. This is unnecessary on x86/x64 but they need to be there for other platforms.
nice find for the similar issue...
I wrote a tentative fix, I've sent a PR. With these fixes, I have no more warning at initialization or at run-time, and Remotery seems still operational. I'm not quite sure of the fix, but you may consider it.
I still have a problem when closing the app though, but this can be investigated later (see below).

SUMMARY: ThreadSanitizer: thread leak Remotery.c:2217 in rmtThread_Constructor
Sorry, I missed this thread. Moved my post upon request. Might be a lot of overlap with previous comments:
I wanted to create a small threaded test to run it through Clang's thread sanitizer, and it seems to produce a lot of output. I'm not sure how many are false positives, but I think it would be great if we could fix them somehow, since I hope more ppl will use the thread sanitizer (and other tools) on their projects in the future.
I have a branch draft here: https://github.com/Celtoys/Remotery/pull/239
I hope I have setup the test correctly. Currently only tested on macOS, but using pthreads, it should work on linux too.
Compile & run with:
clang -std=c89 -DRMT_ENABLED=1 -g -O0 -fsanitize=thread -Ilib sample/thread.c lib/Remotery.c -o build/test && ./build/test
Here's the output for the online readers:
