This doesn't change the behavior when `--jobs`/`-j` is specified as a
command-line argument or in `SCONSFLAGS`.
The SCons hack used to know if `num_jobs` was set by the user is derived
from the MongoDB setup.
We use `os.cpu_count()` for portability (available since Python 3.4).
With 4 CPUs or less, we use the max. With more than 4 we use max - 1 to
preserve some bandwidth for the user's other programs.

We shouldn't presume that future compilers will not have false positives or
find new occurrences of this warning, which would break compiling old versions
of the engine without passing custom `CXXFLAGS`.
Follow-up to #60652.
(cherry picked from commit e55d30768a)
This reverts #53828 which had caused a significant drop in incremental
rebuild time for debug builds (from 10s to 23s on my laptop).
The "faster but unsafe" options are re-added, as well as adding
`max_drift=60` which we didn't use previously.
These options speed up SCons' own processing of the codebase to decide
what to build/rebuild (i.e. the first step before actually calling the
compiler). This will therefore not make much difference for scratch
builds, and is mostly useful for incremental rebuilds (including "null"
rebuilds with no change).
These options are enabled automatically for `debug` builds, unless
`fast_unsafe=no` is passed.
They are disabled by default for `release` and `release_debug` builds,
unless `fast_unsafe=yes` is passed.
(cherry picked from commit d4553c5126)
Debug builds are considerably slower than release builds or even
release_debug builds. `target=debug` is still the default SCons
target option, so unsuspecting users may be compiling unoptimized
debug builds for their personal use.
Change the entire navigation system.
Remove editor prefix from nav mesh generator class. It is now used for baking
at runtime as well.
Navigation supports obstacle avoidance now with the RVO2 library.
Nav system will also automatically link all nav meshes together to form one
overall complete nav map.
The Godot Project Leadership Committe has decided to update the sponsoring
tiers so that the Platinum Sponsorship no longer includes a logo on the
editor splash screen.
This lets us reclaim the editor splash screen space for community-related
content instead of sponsors (e.g. a different community-designed splash
screen for each stable branch?).
Also removes two Platinum Sponsors whose sponsorship has expired earlier this
year.

When disabling specific modules, misspellings can occur. Additionally,
when switching between the `3.x` and `master` branches frequently,
it's possible to forget about renamed modules such as `lightmapper_cpu`
versus `lightmapper_rd`.
(cherry picked from commit 69b2d3f791)
They haven't really helped save much time on incremental rebuilds, and they do
cause potential issues with build correctness (and possibly even one of the cause
for overly eager incremental rebuilds).
(cherry picked from commit 0433d0f54d)
Emscripten is LLVM-based so we want to follow the same logic. But we can't just
put it as a match in `methods.using_clang()` as that would mess with the
compiler version detection logic used to restrict old GCC and Clang releases.
(cherry picked from commit 34421683eb)
It's raised for us on many comparators implemented to be able to store a struct
in `Set` or `Map` (who rely on `operator<` internally). In the cases I reviewed
we don't actually care about the ordering and we use the struct's function
pointers as that's the only distinctive data available.
(cherry picked from commit 802810c371)
This fixes a regression from #46774 where `env["ENV"]` would miss some
important env variables on Windows, such as `SystemRoot`, `PATHEXT`, etc.
So we go back to the previous setup (letting SCons initialize `env["ENV"]`
as it sees fit for the host OS) but use `PrependENVPath` instead of
`AppendENVPath` to preserve the intended fix from #46774.
Fixes#46790 for 3.2.
We constructed the SCons environment without taking any (shell) environment
variables into account, and then appended a few, but too late. This would
cause variables like `env[CXX]` not to be properly expanded to respect a
non-standard `PATH`.
With this fix, setting:
```
PATH=$GODOT_SDK/bin:$PATH
```
will now properly use `$GODOT_SDK/bin/gcc` if available over `/usr/bin/gcc`.
(cherry picked from commit 5d217a9441)
The `dev=yes` and `production=yes` options work as aliases to set a number of
options, while still aiming to allow overriding specific options if the user
wishes so. (E.g. `production=yes use_lto=no` should work to enable production
defaults *but* disable LTO.)
That wasn't working as `ARGUMENTS.get()` returns a string and not a boolean as
expected by `BoolVariable`, and this wasn't flagged as a bug... So added a
helper method using SCons' `BoolVariable._text2bool` to do the conversion
manually.
This adds `custom_modules_recursive` which allows to detect and collect
all nested C++ modules which may reside in any directory specified by
`custom_modules` option.
The detection logic is made to be more strict because `SCSub` may be
used for organizing hierarchical builds within a module itself, so the
existence of `register_types.h` and `config.py` is checked as well
(these are all required for a C++ module to be compiled by Godot).
For performance reasons, built-in modules are not checked recursively,
and there's no benefit of doing so in the first place.
It's now possible to specify a directory path pointing to a *single*
module, as it may contain nested modules which are detected recursively.
(cherry picked from commit a3c2c1e18a)
This is meant for users making custom builds to match the options used on
optimized, official builds.
This enables, on the platforms which support them:
- `use_static_cpp=yes` (portable binaries for Linux and Windows)
- `use_lto=yes` (link time optimizations - note: requires a lot of RAM!)
- `debug_symbols=no` (no debug symbols, smaller binaries)
Also abort when using MSVC with `production=yes`, as:
- It cannot optimize the GDScript VM like GCC or Clang do, leading to
significant performance drops.
- Its LTO support is unreliable, at least used to trigger crashes last
we tried it extensively.
All options can still be overridden if specified, and the `dev=yes` option
was changed to also support overrides.
(cherry picked from commit db26871210)
Fixes a pre-existing bug that #44433 exposed.
It's pretty hacky, but we use `platform` in `env` both as an optional command
line option (instead it can be autodetected, or passed via the `p` alias, and
on Linux it might be overridden if you pass one of the convenience alias
values), and as the reference value for what platform we're building on.
Thus we override `env_base["platform"]` with the autodetected or validated
platform, but any call to `opts.Update(env_base)` overrides it with the
original command line option... causing e.g. #44448.
The proper fix would be to refactor all this so that we don't reuse
`env["platform"]` for platform detection (it could instead be e.g.
`env.platform` as a member variable which holds the validated value),
but for now I'm tapering over the immediate breakage.
Fixes#44448 and other breakages induced by #44433.
(cherry picked from commit 8f660393fe)
Otherwise we can get situations where platform-specific opts with the same name
can override each other depending on the order at which platforms are parsed,
as was the case with `use_static_cpp` in Linux/Windows.
Fixes#44304.
This also has the added benefit that the `scons --help` output will now only
include the options which are relevant for the selected (or detected) platform.
(cherry picked from commit 0f84d8dc49)
A new `methods.dump(env)` is added to dump the construction environment
used by SCons to build Godot to a `.scons_env.json`. The file can be used
for debugging purposes and any external tool.
(cherry picked from commit 42bee75e86)
Some required changes are made:
- locally imported SCons-specific packages within the method;
- `global` variables converted to `nonlocal` (used in nested functions).

Configured for a max line length of 120 characters.
psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:
- Manually wrapped strings will be reflowed, so by using a line length
of 120 for the sake of preserving readability for our long command
calls, it also means that some manually wrapped strings are back on
the same line and should be manually merged again.
- Code generators using string concatenation extensively look awful,
since black puts each operand on a single line. We need to refactor
these generators to use more pythonic string formatting, for which
many options are available (`%`, `format` or f-strings).
- CI checks and a pre-commit hook will be added to ensure that future
buildsystem changes are well-formatted.
(cherry picked from commit cd4e46ee65)
The `custom_modules` option was only read via the command line
by fetching `ARGUMENTS` dictionary directly.
Instead, the option's value can now be read via any existing
configuration files (`custom.py`) as well as command line, while also
updating the environment.
(cherry picked from commit 6304d16915)
The insertion order for dictionaries is only a language feature for
Python 3.6/3.7+ implementations, and not prior to that.
This ensures that the engine won't be rebuilt if the order of detected
modules changes in any way, as the `OrderedDict` should guarantee
inerstion order.
