[ddnet/ddnet] Issue opened: #5834 Initial map change message is sent twice
The initial map change message (NETMSG_MAP_CHANGE) is sent twice by the server for some reason, leading to two HTTP map requests if the map is not present. It should only be sent once.

Do you know if I could somehow pass a held mutex to another function? specifically a std::lock_guard

Mh, maybe just commenting // DONT CALL WITHOUT HOLDING m_Lock is good enough 😄

deen 2022-09-15 17:08:47Z
put the lock_guard in a unique_ptr?

Learath2 2022-09-15 17:08:50Z
and I can check it with TSan if we ever figure out how to get it to work with std::mutex
Avatar
deen 2022-09-15 17:09:00Z
lock_guard locks the mutex on constructor and unlocks on destructor
17:10
at least that sounds reasonable to me to use a unique_ptr for that

Jupstar ✪ 2022-09-15 17:11:05Z
is your goal to check if the mutex is locked inside the function?
Avatar
Learath2 2022-09-15 17:11:55Z
Well the mutex must be held while you call the function, that's the constraint I want to enforce
17:12
Now that I think about it, passing a mutex doesn't work to begin with, no way to make sure it's the mutex I want locked
17:12
I think this is a job for TSan
Avatar
Jupstar ✪ 2022-09-15 17:12:45Z
or just try_lock
17:12
its either locked or you now lock it
Avatar
Learath2 2022-09-15 17:13:30Z
but I don't think that tells me if I hold the lock. The main thread could be holding it aswell
Avatar
Jupstar ✪ 2022-09-15 17:14:08Z
so u want to pass a locked mutex from one thread to another?

No, that's very very undefined anyway 😄

Jupstar ✪ 2022-09-15 17:15:24Z

while(try_lock) probs sucks xD
17:16
if(!has_lock) lock
17:17
i think unique_lock has a check if its locked

Learath2 2022-09-15 17:17:33Z
If try_lock is called by a thread that already owns the mutex, the behavior is undefined.

Jupstar ✪ 2022-09-15 17:17:35Z
"operator bool tests whether the lock owns (i.e., has locked) its associated mutex (public member function)"

A recursive_mutex actually handles it quite well, but I think I'll just add a comment for now and check it with TSan later

Jupstar ✪ 2022-09-15 17:25:50Z
well one way is build a wrapper around the object u protect and take the object as reference in the function auto& obj = wrapper.lock(); func(obj) wrapper.unlock()

It's not useless. It allows you to express that the function consumes some finite resource. For example, if you are trying to collect its return values into an array of length N, then it would be desirable that the function can be called exactly N times. But I'm not sure that Rust is flexible enough to build interfaces on those concepts.

Maybe limiting recursion depth at compile time? Not sure if it's a good idea as it'd cause a lot of code generation

SystemTap, let's you directly instrument syscalls
19:06

19:07
Not really it's intended use, but I've done some very weird inspection with it before. It has a lot of use because you basically can inject code into the kernel
19:09
There is also MSG_PEEK for recv, I just used that in the code instead of debugging
19:09
I guess I could have called MSG_PEEK in gdb, but didn't really feel like malloc'ing in gdb

use gdb and set a watcher on that variable troll
21:01
encapsulate the variable in a class with getters and setters so that you can have a callback for each and every access?

just like signals and slots in Qt

Engine takes jobs, they are ran asynchronously, they have a field m_Status, some processes want to wait until m_Status == DONE

I'm not a big enjoyer of overhead if you haven't noticed that about me

Learath2 2022-09-15 21:27:52Z
Well what annoys me there is that it is much cheaper than the price I have to pay. Futexes are a thing on linux and WaitOnAddress is a thing in NT. It's just that I don't have access to them
