This fixes HashMap where a key or part of a key is a floating point
number. To fix this the following has been done:
* HashMap now takes an extra template argument Comparator. This class
gets used to compare keys. The default Comperator now works correctly
for common types and floating point numbets.
* Variant implements ::hash_compare() now. This function implements
nan-safe comparison for all types with components that contain floating
point numbers.
* Variant now has a VariantComparator which uses Variant::hash_compare()
safely compare floating point components of variant's types.
* The hash functions for floating point numbers will now normalize NaN
values so that all floating point numbers that are NaN hash to the same
value.
C++ module writers that want to use HashMap internally in their modules
can now also safeguard against this crash by defining their on
Comperator class that safely compares their types.
GDScript users, or writers of modules that don't use HashMap internally
in their modules don't need to do anything.
This fixes#7354 and fixes#6947.
We should probably create a specific function for setting the
recv buffer anyway. UDP sockets does not need to bind (listen)
to be able to call recvfrom. This is especially useful for clients
who just call set_send_address and start communicating with a server.
- TCP:
- `listen` bind to wildcard "*" -> dual stack socket
- `listen` bind to address -> socket from address type
- `connect` -> resolve using best protocol (UNSPEC), socket from address type
- UDP:
- `listen` bind to wildcard "*" -> dual stack socket
- `listen` bind to address -> socket from address type
- `put_packet`/`put_var` -> resolve using TYPE_ANY (UNSPEC), socket from address type
(to change socket type you must first call `close` it)
The MinGW-w64 version we have on our Travis build environment (Ubuntu 12.04,
mingw-w64 2.0.1, gcc 4.6) is old and has some missing includes in the
dependencies of the `tcpmib.h` header [0] [1] [2].
Those were not triggered before 6323779596
probably due to conflicting WINVER definitions which prevented triggering the code
specific to >= 0x0600 (Vista). We ensure it won't be triggered by defining the
_WIN32_WINNT macro to Windows XP compatibility.
Passed as a compiler define to be sure it is always define before windows.h
is loaded. This means that Godot officially requires Vista API or later, it will
not work on Windows XP or earlier.
Also fix a bogus check for Windows 7 API.
