The misterious windows networking stack...
Using connect instead of WSAConnect causes socket error 10022 under
certain conditions.
See: https://github.com/godotengine/webrtc-native/ (issue 6)
Having to guess, code path for connect is different then WSAConnect with
NULL extra parameters.
The only reference about weird error with this code mentions something
called "Windows Filtering Platform" but windows internals are, as
always, obscure.
This might be something to try and report to Microsoft if anyone has the
time to spare with the likely outcome of being ignored.
On Unix systems, file descriptors are usually shared among child
processes.
This means, that if we spawn a subprocess (or we fork) like we do in
the editor any open file descriptor will leak to the new process.
This PR sets the close-on-exec flag when opening a file, which causes
the file descriptor to not be shared with the child process.
On Unix systems, sockets are like file descriptors, and file descriptors
are usually shared among child processes.
This means, that if we spawn a subprocess (or we fork) like we do in the
editor, open file descriptors will leak to the new process.
This causes issue with sockets as they might remain open and bound
(listening) when the original process closes.

On some file systems, like ext4 on Linux, readdir() gives enough
information to determine the entry type in order to avoid doing
a stat() system call.
Use this information and call stat() only if necessary: for file
systems that do not support this feature and for links.

Allow getting interfaces names and assigned names.
On UWP this is not supported, and the function will return one interface
for each local address (with interface name the local address itself).
Warnings raised by Emscripten 1.38.0 and MinGW64 5.0.4 / GCC 8.3.0.
JS can now build with `werror=yes warnings=extra`.
MinGW64 still has a few warnings to resolve with `warnings=extra`,
and only one with `warnings=all`.
Part of #29033 and #29801.
- The `cpu-features.{c,h}` code was only used by chance by the webm
(libvpx) code, so I moved it there. It was actually introduced before
that and wasn't in use, and libvpx just happened to be able to
compile thanks to it being bundled.
It could potentially be compiled on the fly from the Android NDK, but
since we plan to replace the webm module by a GDNative plugin in the
near future, I went the bundling route.
- `ifaddrs_android.h` is already provided in the Android NDK as
`ifaddrs.h`, same as on other Unixes. Yet we cannot use it until we
up the min API level to 24, where `getifaddrs` is first defined.
I moved the files to `thirdparty/misc` and synced them with upstream
WebRTC (only indentation changes and removal of `static` qualifiers).
Also removes dropped thirdparty files from COPYRIGHT.txt after changes
in #24105 and #24145.

Since Windows 2000:
Calling recv/recvfrom when an ICMP reply was received from a previous
send/sendto, may result in a WSAECONNRESET error.
Since Windows Vista(?)/Windows Server 2008:
Calling recv/recvfrom when an ICMP reply was received from a previous
send/sendto, may also result in a WSAENETRESET error.
Both those features are disabled by this commit using disabling
SIO_UDP_CONNRESET and SIO_UDP_NETRESET on newly created UDP sockets.
WSAPoll is broken by design.
It was announced as the new way to introduce compatibility to posix
sockets, their implementation was broken, and they decided not to fix it.
You can read the full story here:
https://daniel.haxx.se/blog/2012/10/10/wsapoll-is-broken/
Unified BSD and Winsock sockets into a single implementation of a
generic NetSocket interface.
This is some ground work for few network improvements:
- Reuse as much code as possible between Posix and Windows.
- Provide a single point of implementation for exotic sdks (consoles).
- Provide platform agnostic StreamPeerTCP and PacketPeerUDP in core.
- Implement connect for UDP allowing for DTLS implementation.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
Use a Microsoft recommended way of process termination for the project
process run from the editor. This allows loaded DLLs to receive and handle
DLL_PROCESS_DETACH notification and cleanup any global state before the
process actually exits.
Implements the same heuristic as Curl (and web browsers): if no `Content-Length`, no `Connection: keep-alive` and no chunked transfer encoding, assume th rest of the data until EOF is the body, gracefully setting the HTTP client back to the disconnected state.
Theoretically, this is not compliant with HTTP 1.1, by which `keep-alive` is the default, but in practice, an explicit header is sent by servers.
- Adds q/quit option to console debugging
- Adds options (variable_prefix)
- Breaks into debugger with Ctrl-C in local debug mode (Unix/Windows)
- Added option to list all breakpoints
- Fixes add/remove breakpoint bug (invalid path parsing)
- Minor cleanup
when godot could be found in PATH.
The correct fix is to use sysctl to get the path to the current executable
this also fixes the ability to call external commands.
Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.
As spotted by @robfram, closes#15288.
Also reviewed other uses of `if (String.find(.*))` for potential similar mistakes, found a wrong (and useless) one in ScriptEditorDialog.
They are NOT constant methods, as state by the comment message,
they fetch the last packet and then forget about it, actively
changing the state of the object.
This allows to specify any valid folder name (including with subfolders) to use
as user:// on all platforms. The folder is constrained to the platform-specific
OS::get_data_path() (typically what `XDG_DATA_HOME` resolves to).
Fixes#13236.
Spec version 0.7 from https://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
(latest as of this commit).
Three virtual methods are added to OS for the various XDG paths we will use:
- OS::get_data_path gives XDG_DATA_HOME, or if missing:
~/.local/share on X11, ~/Library/Application Support/ on macOS and %APPDATA% on Windows
- OS::get_config_path gives XDG_CONFIG_HOME, or if missing:
~/.config on X11, ~/Library/Application Support/ on macOS and %APPDATA% on Windows
- OS::get_cache_path gives XDG_CACHE_HOME, or if missing:
~/.cache on X11, ~/Library/Caches on macOS and %APPDATA% on Windows
So for Windows there are no changes, for Linux we follow the full split spec
and for macOS stuff will move from ~/.godot to ~/Library/Application Support/Godot.
Support for system-wide installation of templates on Unix was removed for now,
as it's a bit hackish and I don't think anyone uses it.
user:// will still be OS::get_data_path() + "/godot/app_userdata/$name" by
default, but when using the application/config/use_shared_user_dir option
it will now use XDG_DATA_HOME/$name, e.g. ~/.local/share/MyGame.
For now everything still goes in EditorSettings::get_settings_dir(), but
this will be changed in a later commit to make use of the new splitting
where relevant.
Part of #3513.
It had been missed in d09160a8b6 and broke compilation
for those platforms.
Took the opportunity to run clang-format on the code base to fix some corner cases
that went through our static tests/were overlooked recently.
Previously logging logic was scattered over OS class implementations
with plenty of duplication. Major changes in this commit:
- Extracted logging logic into a separate Logger hierarchy. It allows
easy configuration of logging mechanism depending on compile-time or
run-time configuration.
- Implemented RotatedFileLogger which is usually used with StdLogger,
providing persistency of logs. It is often important to be able to
obtain logs of the game even in production to be able to understand
what happened prior to some problem. On mobile there previously was
no way to obtain the logs aside from having the device connected to
your machine.
- flush() is not performed in release mode for every logged line. It
is only performed for errors.
Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:
* pos -> position
* rot -> rotation
* loc -> location
C++ variables are left as is.
As it turns out older versions of the Android NDK have mntent.h but not
a complete implementation. If it did work it would most likely give the
wrong results on Android anyway.
This commit enables the UNIX drive discovery only for X11
We also missed '/run/media' (default for gnome desktops) in the list of
places to look for 'drives' on Linux. Add that to the list also.
This fixes#11270
In #10973 I reset the state of the stream in get_pos() assuming that the
ftell failing would cause proper error checking. This is not how this
class was designed, however. This commit fixes the get_8() method to
not return unitialized data on eof, and removes the wrong error resets
added in #10973.
This fixes#11022
- The Windows, UWP, Android (on Windows) and Linux builds are
tested with Scons 3.0 alpha using Python 3.
- OSX and iOS should hopefully work but are not tested since
I don't have a Mac.
- Builds using SCons 2.5 and Python 2 should not be impacted.
For every UNIX-derived (Android, Linux, macOS, iOS) flavor, a global counter is atomically incremented on thread start. That id is kept as thread-local storage.
Therefore, thread ids are sequential numbers, trivially comparable. This improves the previous state of things, in which `pthread_t` were casted to `Thread::ID` and unportabily compared. Also big, ugly thread ids appeared.
Implemented with `nanosleep()`. `usleep()` is deprecated.
Also loops to ensure that __at least__ the requested time is waited, accounting for spurious interruptions.
May help in situations like reattempting to connect to the debugger.
When looking up a symbol from a library, previously an error was
shown when the symbol did not exist. That caused confusion when the
lookup was completely optional.
This adds a new parameter to that method so that those errors can
be handled manually if needed.
This module was written by bojidar-bg and me, with the help of ClikCode and touilleMan.
This adds a module to Godot that enables the use of dynamic libraries as a source for scripts.
That also allows third party libraries to be linked to Godot more easily and without creating modules.

I can show you the code
Pretty, with proper whitespace
Tell me, coder, now when did
You last write readable code?
I can open your eyes
Make you see your bad indent
Force you to respect the style
The core devs agreed upon
A whole new world
A new fantastic code format
A de facto standard
With some sugar
Enforced with clang-format
A whole new world
A dazzling style we all dreamed of
And when we read it through
It's crystal clear
That now we're in a whole new world of code
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)
