licensing: convert "public domain" to CC0 1.0
Public domain does not have an internationally agreed upon definition,
As such it's generally preferred to use an extremely liberal license,
which can explicitly list the rights granted by the copyright holder.
The CC0 license is the usual choice here.

This "relicensing" is done without hunting down copyright holders, since
it is presumed that their release of this work into the public domain
authorizes us to redistribute this code under any other license of our
choosing.

Lioncash b425250a7b TraversalClient: Make use of std::string_view with ConnectToClient()
Same behavior, but allows the use of non-allocating string types with
the interface.

Lioncash cb4ca7837a TraversalClient: Prevent uninitialized values from occurring in MakeENetAddress
Previously, eaddr would only be partially initialized in the ipv6 case.
Even if there's no support for it, we may as well ensure that the
variable always has deterministic initialization.

While we're at it, we can make the parameter a const reference, given no
members are modified.

Lioncash d2ea94195c TraversalProto: Convert TraversalPacketType into an enum class
Makes for strong typing and prevents namespace pollution.

Lioncash 2021175809 TraversalClient: Convert state enum into an enum class
Prevents implicit conversions and prevents identifiers from polluting
the class scope.

Lioncash 139d4fc76e General: Convert PanicAlerts over to fmt equivalent
Converts lingering panic alert calls over to the fmt-capable ones.

Lioncash 4e8df93f41 Common: Migrate logging to fmt
Continues the migration of our code over to the fmt logger.

Techjar d94922002b NetPlay: Implement chunked data transfer
This sends arbitrary packets in chunks to be reassembled at the other
end, allowing large data transfers to be speed-limited and interleaved
with other packets being sent. It also enables tracking the progress of
large data transfers.

Lioncash 189d277cfc Common/Random: Add convenience template for simple arithmetic values
In cases where we just want a random value for a primitive arithmetic
type, we can wrap this in a template to allow convenient direct
assignment instead of keeping declaration and initialization separate
(making it more difficult to use values uninitialized). This also allows
the use of Common::Random with functions such as std::generate, making
it more flexible in how random values can be generated.

Léo Lam fff1db9730 Common: Add Random utilities
This makes it easier to generate random numbers or fill a buffer with
random data in a cryptographically secure way.

This also replaces existing usages of RNG functions in the codebase:

* <random> is pretty hard to use correctly, and std::random_device does
  not give enough guarantees about its results (it's
  implementation-defined, non cryptographically secure and could be
  deterministic on some platforms).
  Doing things correctly is error prone and verbose.

* rand() is terrible and should not be used especially in crypto code.

TraversalClient: Use u32 instead of enet_uint32
Lessens the dependence on the enet library (and we really don't need to rely on a third-party library for a 32-bit integer type)

TraversalClient: In-class initialize members where applicable 2018-04-16 16:46:48 -04:00
Lioncash ca6a2970ea
TraversalClient: Make data externally read-only members private
These are only ever queried for state, not written. Therefore, prevent writing to the members
and make them private.

Lioncash 696e1b40b5 Common: Move version strings to their own header
Ideally Common.h wouldn't be a header in the Common library, and instead be renamed to something else, like PlatformCompatibility.h or something, but even then, there's still some things in the header that don't really fall under that label

This moves the version strings out to their own version header that doesn't dump a bunch of other unrelated things into scope, like what Common.h was doing.

This also places them into the Common namespace, as opposed to letting them sit in the global namespace.

Lioncash 5859914da5 TraversalClient: Fix memory leaks in ReleaseTraversalClient()
release() relinquishes ownership of a pointer, it doesn't actually free
it.

Aestek 6a0fc4c438 Improve netplay setup dialog UX
* Focus "Hash Code" / "IP address" text box by default in "Connect"
* Focus game list in "Host" tab
* RETURN keypress now host/join depending on selected tab
* Remember last hosted game
* Remove PanicAlertT:
	* Simply log message to netplay window
	* Remove them when they are useless
* Show some netplay message in OSD
	* Chat messages
	* Pad buffer changes
	* Desync alerts
* Stop the game consistently when another player disconnects / crashes
* Prettify chat textbox
* Log netplay ping to OSD

Join scenario:
* Copy netplay code
* Open netplay
* Paste code
* Press enter

Host scenario:
* Open netplay
* Go to host tab
* Press enter

mathieui 8201a52cec Traversal: Use a decent PRNG instead of rand()
we don’t need cryptosecure random, but having a uniform distribution is
always better.

mathieui e0ef8fc03f NetPlay: Make the enet interrupts work
Otherwise, it would work but any async sending would be delayed by 4ms or
wait until the next packet was received.

Also increase the client timeout to 250ms, since enet_host_service is now
really interrupted.
