2021-02-18Linux: Fix fallback logic when udev fails creating a contextRémi Verschelde
Thanks to Noshyaar for pointing out the bug.
2021-02-18Don't clobber original library symbolsHein-Pieter van Braam-Stewart
It appears that we can get a fun circle dependency on a shared object on some system configurations causing issues with our 'fake' function pointer names. This can lead to a crash. The new wrapper generator renames all the symbols so this can't happen anymore. See https://github.com/hpvb/dynload-wrapper/commit/704135e This closes #46140
2021-02-17Dynamically load libudev.so.1 on Linux if `udev=yes`Rémi Verschelde
This makes it possibly to run Linux binaries compiled with udev support on Linux systems which do not provide udev (typically systemd-less distros). If udev is missing, we fall back to parsing `/dev/input` like when compiled without udev support (`udev=no`). Also adding some verbose debug statements to know which method we're using when debugging Linux joypad issues. The libudev so wrappers were generated on Mageia 8 with libudev 246.9 using https://github.com/hpvb/dynload-wrapper: ``` ./generate-wrapper.py --include /usr/include/libudev.h --sys-include '<libudev.h>' \ --soname libudev.so.1 --init-name libudev --omit-prefix gnu_ \ --output-header libudev-so_wrap.h --output-implementation libudev-so_wrap.c ```
2021-02-16Dynamically load libpulse.so.0 and libasound.so.1 on LinuxHein-Pieter van Braam-Stewart
By generating stubs using https://github.com/hpvb/dynload-wrapper we can dynamically load libpulse and libasound on systems where it is available. Both are still a build-time requirement but no longer a run-time dependency. For maintenance purposes the wrappers should not need to be re-generated unless we want to bump pulse or asound to an incompatible version. It is unlikely we will want to do this any time soon. This closes #20978
2021-02-08SCons: Fix debug_symbols tests after switch to BoolVariableRémi Verschelde
Bug introduced in #45679. Fixes part of #45816.
2021-02-03SCons: Add `production=yes` option to use production defaultsRémi Verschelde
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.

Linux: Enable udev support by default
2021-02-01Linux: Build with use_static_cpp=yes by default for x86_64Rémi Verschelde
This enables `-static-libgcc -static-libstdc++` which help make custom Linux builds more portable (official builds have been using this option for years). For some obscure reason Ubuntu 18.04 i386 crashes when using the option for i386 builds, so let's play it safe and enable for x86_64 only for now.
2021-02-01Linux: Enable udev support by defaultRémi Verschelde
This has been enabled for years in official binaries, and users making custom builds may end up not enabling it unknowingly, so it's best if we default to the same as what official builds do. The original reason for having it opt-in was likely the addition of a dependency on libudev, but that should be fairly ubiquitous by now.

2021-01-27Go through all event devices, not just event[0-32]Jari Ronkainen
There are no guarantees that joypads are in event0-event32 range. Some devices, such as laptops with detachable keyboards and wacom can reserve events all the way up to 32. Some udev rules with e.g. custom controller firmwares may load the device as /dev/input/eventX, where X is greater than 32. This patch uses POSIX dirent to enumerate the event devices, so entries outside 0-32 range are not skipped.

2021-01-01Update copyright statements to 2021Rémi Verschelde
Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆

2020-12-16SCons: Add only selected platform's opts to envRémi Verschelde
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.

2020-11-19SCons: Remove unnecessary $LINK overridesRémi Verschelde
As of SCons 4.0.1, the default value for $LINK is $SMARTLINK, which itself is a function that will use $CXX as linker for C++: https://github.com/SCons/scons/blob/4.0.1/SCons/Tool/link.py#L327-L328 https://github.com/SCons/scons/blob/4.0.1/SCons/Tool/link.py#L54-L76 So we don't need to manually specify the same value as $CXX for $LINK.

2020-11-11Fix for linux joypad D-pad zeroingConnor Lirot
Some controllers (notably those made by 8bitdo) do not always emit an event to zero out a D-pad axis before flipping direction. For example, when rolling around aggressively the D-pad of an 8bitdo SN30 Pro/Pro+, the following may be observed: ``` ABS_HAT0X : -1 ABS_HAT0Y : -1 ABS_HAT0Y : 0 ABS_HAT0Y : 1 ABS_HAT0X : 1 ``` Notable here is that no event for `ABS_HAT0X: 0` is emitted between the events for `ABS_HAT0X: -1` and `ABS_HAT0X: 1`. Consequently, the game engine believes that both the negative _and_ positive x-axis directions of the D-pad are activated simultaneously (i.e `is_joy_button_pressed()` returns `true` for both `JOY_BUTTON_DPAD_LEFT` and `JOY_BUTTON_DPAD_RIGHT`), which should be impossible. This issue is _not_ reproducible on all controllers. The Xbox One controller in particular will not exhibit this problem (it always emits zeroing out events for an axis before flipping direction). The fix is to always zero out the opposite direction on the D-pad axis in question when processing an event with a nonzero value. This unfortunately wastes a small number of CPU cycles on controllers that behave nicely. **I have verified this issue is also reproducible in the stable 3.2 branch**
2020-11-09Remove `debug_symbols=full` in favor of `debug_symbols=yes`Hugo Locurcio
`debug_symbols=yes` will now behave like `debug_symbols=full` did before. The difference in compressed file sizes is not that large, which means there isn't much point in having two different values. This helps make the buildsystem easier to understand.

2020-10-09Implement SAVE_TARGETS mechanism for Linux clipboardPouleyKetchoupp
Allows sending the clipboard content to the clipboard manager on exit to keep the content when using a clipboard manager that doesn't automatically makes a backup when copying. MULTIPLE selection mechanism also had to be implemented, because in this case, the clipboard manager might request multiple selection targets at once. Known use case: Ubuntu with XFCE4
2020-10-08Fix x11 display server crash when deleting popup window when unfocusedPouleyKetchoupp
On FocusOut events, the window could be destroyed while propagating WINDOW_EVENT_FOCUS_OUT event, which causes the WindowData to be invalidated, and still used for calls to XUnsetICFocus. This change moves calls to XUnsetICFocus, and also XSetICFocus in FocusIn events, before propagating the change of focus event to the engine, to be safe in any case. Also setting xic member to nullptr after all calls to XDestroyIC to keep things clean and consistent. Fixes #42645
2020-09-25Fix delay to process clipboard content from Godot in other programsPouleyKetchoupp
When pasting clipboard content from Godot to other applications, multiple SelectionRequest events are sent to Godot in order to access the data. It could take a long time before the data is ready for the other app because events were processed one by one on the main thread, especially when Godot is unfocused and runs at low frequency. With this change, SelectionRequest events are directly handled on the separate event polling thread to minimize this delay. This change also replaces clipboard_get() calls in SelectionRequest with a direct access to internal_clipboard, since in this case we know Godot is the owner of the clipboard content and it's not necessary to query the x server for it.
2020-09-24Fix general keyboard input lag on X11 display serverPouleyKetchoupp
This change makes keyboard inputs more responsive on Linux, especially when the FPS is lower on slower configurations. Polling events from the x server is done on a separate thread to avoid a frame delay with inputs, due to first sending the event to the input manager with XFilterEvent then processing the new event only on the next frame. Calls to Input Manager functions like XSetICFocus, XUnsetICFocus and XSetICValues use a mutex, because they are polling events internally and would otherwise interfere with our own thread process for polling events which can cause a deadlock in some cases. XUnsetICFocus is called instead of XSetICFocus on FocusOut events, so the input manager can be properly notified of focus changes. clipboard_get now uses a blocking call to poll for a specific event type when waiting for a SelectionNotify event, instead of polling all events and filtering them afterwards.
