Crashing when registering/refreshing #4

Closed Dids closed 8 years ago

Dids commented 8 years ago

Whenever I try to register a new server or refresh the server list (eg. whenever I try to connect to the server), UE just decides to crash.

It seems like an array issue (out of bounds etc)?

Hey, does it appear to do it the second time you attempt to transmit a request? Ie. First time succeeds and second time fails. I'll take a look at this tommorw and see if I can replicate it (inter ally I have refined this and longer use it as a plugin so it doesn't get tested much on new UE4 versions)

Dids commented 8 years ago

Nope, sadly it appears to happen the first time a function on MasterServer is called.

I did just try debugging the entire project, and it's throwing a breakpoint on the following (internal) line:

ensureMsgf(this->IsBound(), TEXT("Unable to bind delegate to '%s' (function might not be marked as a UFUNCTION)"), InMacroFunctionName);

I see that it's trying to call MyGameInstance::OnServerRegistered, then throwing the previous line.

EDIT: Nevermind that, that might actually just be a bug in UE4/VS debugging.

Dids commented 8 years ago

After stepping over the delegate breakpoints, I got to the meat of the issue.

It would seem like MasterServerFunctions is calling TransmitRequest, and there's a TArray allocation issue, possibly a pointer gone wild?

EDIT: I think it's the RequestQueue property that's causing the issue, still drilling down.

I'm assuming this is not because I'm using EHttpResponse objects instead of FHttpResponse?

Are you trying to pass a EHttpRequest into the transmit request? That's probably it, you can see the definition of the FHttpResponse in the masterserverfunctions header, I believe it will make it clear. Otherwise, if doesn't help I will get back to you in the morning :

Whenever I try to register a new server or refresh the server list (eg. whenever I try to connect to the server), UE just decides to crash.

I'm assuming this is not because I'm using EHttpResponse objects instead of FHttpResponse?

No, the entire "FHttpResponse" thing was just a typo in the README.md, as far as I can see (had to be EHttpResponse instead, when defining the delegates).

I'm unable to get a clear picture on what's actually causing the crash, because depending on what function I call (ie. register server, refresh server list etc.), it produces a different crash, all pointing to a memory-related issue (released pointers etc.).

Dids commented 8 years ago

When registering a new server, the crashes seem to be pointing at the following two lines in MasterServerFunctions.cpp:

ServerRegisteredEvent.RemoveDynamic(this, &UMasterServerFunctions::OnRegisteredServer);
ServerRegisteredEvent.AddDynamic(this, &UMasterServerFunctions::OnRegisteredServer);

Managed to figure out. Since I'm new to UE (but a long time user of C++), I didn't know that I had to set the UMasterServerFunctions property as a UPROPERTY(). After I did that, everything started working as it should.

Ah woops browsing on my phone and didn't see you fixed already! Good job :)

Oh OK yeah that would of gone to the output window - simply marking any function you wish to use dynamic delegates with as UFUNCTION() should fix :)

Nope, sadly it appears to happen the first time a function on MasterServer is called.

I did just try debugging the entire project, and it's throwing a breakpoint on the following (internal) line:

ensureMsgf(this->IsBound(), TEXT("Unable to bind delegate to '%s' (function might not be marked as a UFUNCTION)"), InMacroFunctionName);

I see that it's trying to call *MyGameInstance::OnServerRegistered, then throwing the previous line.
