		vladislavbelovUnsubmitted Not Done Inline Actions r-value doesn't make things easier here. vladislavbelov: r-value doesn't make things easier here.
		irishninjaAuthorUnsubmitted Done Inline Actions My thinking had been that game messages do not need to be used after they are "sent" so I could pass them as an r-value. This should help avoid any additional copying and make it more clear in the code that the message has been "consumed" (so it shouldn't be edited afterwards, etc). Does that make sense? irishninja: My thinking had been that game messages do not need to be used after they are "sent" so I could…

		irishninjaAuthorUnsubmitted Done Inline Actions I am setting `m_GameMessage` to reference `msg` (which is on the stack). This doesn't result in any issues since `m_GameMessage` only needs to be available until `m_MsgApplied.wait(msgLock)` unblocks which certainly is within the lifetime of the previous stack frame (either `Step` or `Reset`). I will probably update this to use an rvalue ref (and use `std::move`) to make ownership more obvious... Thoughts? irishninja: I am setting `m_GameMessage` to reference `msg` (which is on the stack). This doesn't result in…
		vladislavbelovUnsubmitted Not Done Inline Actions Yes, and that should be avoided. We shouldn't store pointers/references to local variables as class members until we explicitly guarantee the lifetime. vladislavbelov: Yes, and that should be avoided. We shouldn't store pointers/references to local variables as…

		vladislavbelovUnsubmitted Not Done Inline Actions The issue is still here. You're storying reference to a local variable. vladislavbelov: The issue is still here. You're storying reference to a local variable.
		irishninjaAuthorUnsubmitted Done Inline Actions Adding `m_GameMessage = std::move(msg);` should fix this here, right? I was thinking that it should help since the variable is moved to the data member and will no longer be freed after it goes out of scope (ie, when the variable frame is popped off the stack). Is this correct or am I missing something? irishninja: Adding `m_GameMessage = std::move(msg);` should fix this here, right? I was thinking that it…

		irishninjaAuthorUnsubmitted Done Inline Actions Hmm... I was assuming that it was a properly formed HTTP request. Would you like me to be more pessimistic about malformed HTTP requests? So far, I haven't worried too much about it since "Content-Length" is often handled by http request libraries and the RL interface requires both a flag to be set and then only accepts requests from localhost (unless you change the address to 0.0.0.0). I also figured that there wasn't much motivation for malicious agents to attack the game via the RL interface as it is likely being used for development of an AI rather than a hosting the game engine as a server of sorts. (In that context, I had actually imagined there would still be an orchestrator of sorts collecting and applying the commands as all actions at a given step are part of a single call to `Step` - and it likely wouldn't make sense for both players to control the stepping of the game arbitrarily.) Regardless, I can certainly update it if preferred. Let me know what you think! irishninja: Hmm... I was assuming that it was a properly formed HTTP request. Would you like me to be more…
