GLAD 1 creates unusable loaders for EGL, while the newly released GLAD 2
does not, so for consistency I thought that it would be a good idea to
uniform things beforehand. While it had some API changes some renames
were all that was needed and everything works like before, at least on
the Wayland branch.
I've kept the structure identical, although this new generator has quite
a few hefty features, such as a single header mode.
I've also added GLAD to `thirdparty/README.md`, but I haven't specified
that in the commit title because it's a very small "fix".
The exit code is initialized as EXIT_FAILURE to indicate failures during
startup. Closing the Game window via the window manager does not
change the exit code, so the program exists with EXIT_FAILURE.
This PR set the exit code to EXIT_SUCCESS when initialization was
successful just before starting the main loop.
On X11 we rely on ConfigureNotify event to update rendering context
window size, but we don't get such event when resizing
programmatically, only when done "manually" by resizing the window
etc.
Replace all TODO uses of `#warning` by proper TODO comments, and will open
matching bug reports to keep track of them.
We don't have a great track record fixing TODOs, but I'd wager we're even
worse for fixing these "TODO #warning" so we should prohibit this usage.
- `LIBC_FILEIO_ENABLED` wasn't defined anywhere, even in _other platforms_.
- `NO_NETWORK` is also never defined. It probably isn't enough anyway to
disable network APIs in the current codebase.
- `UNIX_SOCKET_UNAVAILABLE` is never defined in this code but used by some
other platforms, clarify that.
- `NO_STATVFS` can be removed as Android supports it since API level 19,
which is our current min SDK level. It's also only used for
`DirAccessUnix::get_space_left()` which is anyway overridden by
`DirAccessJAndroid::get_space_left()` so it shouldn't make a difference.
* Fixed documentation for `DirAccess.get_space_left()`.
- `NO_FCNTL` is likely also a remnant of early Android days, in current NDK
r23 it seems to be available. Also cleaned up unused `fcntl.h` includes.
- `NO_ALLOCA` is never defined, and we use alloca in many places now.
Fixes#66413.
DisplayServerX11 tracks some internal state about whether the window is
fullscreen, minimized, maximized or none. This commit queries the
display server when the window changes, so that this internal state can
be correctly updated.
Implements https://github.com/godotengine/godot-proposals/issues/3371.
New `target` presets
====================
The `tools` option is removed and `target` changes to use three new presets,
which match the builds users are familiar with. These targets control the
default optimization level and enable editor-specific and debugging code:
- `editor`: Replaces `tools=yes target=release_debug`.
* Defines: `TOOLS_ENABLED`, `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_debug`: Replaces `tools=no target=release_debug`.
* Defines: `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_release`: Replaces `tools=no target=release`.
* Defines: `-O3`/`/O2`
New `dev_build` option
======================
The previous `target=debug` is now replaced by a separate `dev_build=yes`
option, which can be used in combination with either of the three targets,
and changes the following:
- `dev_build`: Defines `DEV_ENABLED`, disables optimization (`-O0`/`/0d`),
enables generating debug symbols, does not define `NDEBUG` so `assert()`
works in thirdparty libraries, adds a `.dev` suffix to the binary name.
Note: Unlike previously, `dev_build` defaults to off so that users who
compile Godot from source get an optimized and small build by default.
Engine contributors should now set `dev_build=yes` in their build scripts or
IDE configuration manually.
Changed binary names
====================
The name of generated binaries and object files are changed too, to follow
this format:
`godot.<platform>.<target>[.dev][.double].<arch>[.<extra_suffix>][.<ext>]`
For example:
- `godot.linuxbsd.editor.dev.arm64`
- `godot.windows.template_release.double.x86_64.mono.exe`
Be sure to update your links/scripts/IDE config accordingly.
More flexible `optimize` and `debug_symbols` options
====================================================
The optimization level and whether to generate debug symbols can be further
specified with the `optimize` and `debug_symbols` options. So the default
values listed above for the various `target` and `dev_build` combinations
are indicative and can be replaced when compiling, e.g.:
`scons p=linuxbsd target=template_debug dev_build=yes optimize=debug`
will make a "debug" export template with dev-only code enabled, `-Og`
optimization level for GCC/Clang, and debug symbols. Perfect for debugging
complex crashes at runtime in an exported project.
Instead of updating all viewports, then blitting all viewports
to the backbuffer, then swapping all buffers, we run through
all viewports and render, blit, and swap backbuffer before
going to the next viewport.
Adds support for LTO on macOS and Android. We don't have much experience
with LTO on these platforms so for now we keep it disabled by default
even when `production=yes` is set.
Similarly for iOS where we ship object files for the user to link in
Xcode so LTO makes builds extremely slow to link.
`production=yes` defaults to full LTO.
ThinLTO is much faster for LLVM-based compilers but seems to produce
bigger binaries (at least for the Web platform).
Fixes a crash due to an Xlib error, as well as ensures that Godot
holds the correct size of the window after window modes have been
applied, before exiting the DisplayServerX11 constructor. This ensures
the bootsplash will be displayed with the correct dimensions.
Fixes#65320
The DisplayServerX11 constructor processes pending events shortly
after constructing the main window. However, it discards pending events
on the event queue that it is not interested in. This results in these
events never making it to the main events thread and as a result are
never processed. We need to save the events we don't handle in
DisplayServerX11 so that they can be resent for later handling by the
events thread.
Attempts to construct an X11 window in an initial state of
minimized/maximized would fail due to the window being unmapped.
We simply check for failed mode changes during an unmap and reapply
them if necessary.
Attempts to set a Godot window to fullscreen prior to the window being
mapped would silently fail. This commit uses
_window_fullscreen_check to test if a window had been set to fullscreen
while unmapped, and if so, resets it to fullscreen once the window has
been successfully mapped.
Fixes#54065
The new option is `linker` and lets the user specify the argument to
the`-fuse_ld=` linker flag directly. The supported options are:
- `default`: No change, typically uses GNU ld (bfd) unless the user or
distro picked a different default `/usr/bin/ld`.
- `bfd`: GNU ld from binutils
- `gold`: GNU gold from binutils
- `lld`: lld from LLVM
- `mold`: mold, an extremely fast modern linker, not (yet) intended for
use in production but great for development speed. Provided by distro
`mold` package or needs to be compiled from source and installed to
`/usr` otherwise.
Removes the `use_lld=yes` option, and make lld actually usable with GCC
too.
Not all the above are compatible or recommend for LTO, we recommend
using GNU ld with GCC LTO, or lld with LLVM ThinLTO.
Now the `linuxbsd` platform can be built headlessly (e.g. without X11
development libraries).
I also cleaned up some weird (old?) usages of the `env` variable which
seem to make no difference and are used nowhere else.
This is in line with what's reported by the `OS` class on GNU/Linux, and
is required by the extension exporter to identify the correct library.
For BSD, we should either finish splitting the platform (into
platform/bsd) or register a separate exporter with OS name BSD and
proper templates detection.
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
These typedefs don't save much typing compared to the full `Ref<Resource>`
and `Ref<RefCounted>`, yet they sometimes introduce confusion among
new contributors.
Didn't commit all the changes where it wants to initialize a struct
with `{}`. Should be reviewed in a separate PR.
Option `IgnoreArrays` enabled for now to be conservative, can be
disabled to see if it proposes more useful changes.
Also fixed manually a handful of other missing initializations / moved
some from constructors.
It's not needed on most distros as those are found in standard lib
and include paths, but on NixOS they're all in non-standard prefixes,
so we need to rely on information provided by pkg-config.
Fixes#59913.

Windows export process:
Limit size of executable with embedded PCK to 4 GB.
Use "rcedit" before embedding PCK.
Capture and process "rcedit" errors.
Windows, Linux:
Add support for PCK loading from executable "pck" section.
`DirAccess *` needs to be deleted manually, and this is often forgotten
especially when doing early returns with `ERR_FAIL_COND`.
`DirAccessRef` is deleted automatically when it goes out of scope.

It has been disabled in `master` since one year (#45852) and our plan
is for Bullet, and possibly other thirdparty physics engines, to be
implemented via GDExtension so that they can be selected by the users
who need them.
