I had missed a special case check for userdata of two colliding objects being equal. In this case, collisions should not be reported. This is used in the physics to prevent self intersection in composite objects.
This commit changes the way Thread::caller_id works. By moving caller_id
to the .cpp file we make sure that the TLS variable doesn't get
relocated twice causing a crash. Since we build with LTO for release
builds (and everyone should be doing that anyway) there is no extra
overhead from the non-static method. We do do an extra bool check now
there but I don't think this will add much in the way of overhead.
This check cannot be avoided if we still want to be able to cache the
thread ID hash, as we had to move the setter because of limitations of
the WinRT platform. The original workaround for this was in #46813 but
this has some unintended consequences. Specifically; threads that never
create a Thread object will always return 0 in Thread::get_caller_id()
which caused a regression. For instance the editor now freezes when
importing large textures. This PR also addresses that.
Additionally we now enable ASLR support when building with MingW, this
includes a workaround for MingW. MingW refuses to create an appropriate
relocation table if no symbols are exported. So we just export the
various main() functions in godot_windows.cpp.
While ASLR support isn't criticial for Godot, previous versions of Godot
just happened to work with a dynamic base 'by accident' and some users
run Godot this way. After the thread change the .tls section now needs
relocations to make this work. By enabling ASLR at build-time we create
these relocations and people who forced ALSR on previously will now get
a working Godot again.
This fixes#47256 and fixes#47219
This is the 3.x version of this PR. For master a different approach is
possible which I will make in the coming days.
Having to rename project settings is rare, but when it does occur it can cause user confusion. In order to make compatibility more seamless this PR introduces two new GLOBAL_DEF functions,
GLOBAL_DEF_ALIAS(new_name, old_name, default)
GLOBAL_DEF_ALIAS_RST(new_name, old_name, default)
These are the same as the existing GLOBAL_DEF functions except that if the new setting is not found, it attempts to load from the old setting name. If the old setting is found, it stores it into the new setting, and then calls the regular GLOBAL_DEF functions.
More work is needed to make sure that those options actually solve users' issues, so we prefer to remove the options for 3.2.4 and revisit for a future release.
The problem happened because `poll` assumed that when the SSL flag was
true, the `connection` would be a subclass of StreamPeerSSL. However
that invariant could be broken by calling HTTPClient::set_connection
with a `connection` that is not a subclass of StreamPeerSSL.
Fixes#46138
(cherry picked from commit a3a731ed92)
The rendering/quality/2d section of project settings is becoming considerably expanded in 3.2.4, and arguably was not the correct place for settings that were not really to do with quality.
3.2.4 is the last sensible opportunity we will have to move these settings, as the only existing one likely to break compatibility in a small way is `pixel_snap`, and given that the whole snapping area is being overhauled we can draw attention to the fact it has changed in the release notes.
Class reference is also updated and slightly improved.
`pixel_snap` is renamed to `gpu_pixel_snap` in the project settings and code to help differentiate from CPU side transform snapping.
- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile` by the new `SafeFlag`
- Platform-specific implementations no longer needed

- Based on C++11's `thread` and `thread_local`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed (except for the few cases of non-portable functions)
- Simpler for `NO_THREADS`
- Thread ids are now the same across platforms (main is 1; others follow)
- Based on C++11's `mutex` and `condition_variable`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed

- Based on C++11's `mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
- `BinaryMutex` added for special cases as the non-recursive version
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.

- No more need to allocate-deallocate or check for null
