Conversely, a "stacking" screensaver suspension paradigm allows +for parallel suspension, such that suspending calls are expected to be +matched by an equal number of un-suspending calls. + +Documentation for `PlatformScreen::SetScreenSaverSuspended` (inherited +by `X11ScreenOzone`) explains that it should be used in a non-stacking +manner [1], which contradicts the child class's underlying +implementation [2]. + +> If XScreenSaverSuspend is called multiple times with suspend set to +> 'True', it must be called an equal number of times with suspend set +> to 'False' in order for the screensaver timer to be restarted. + +This change updates the documentation/API of the `PlatformScreen` +parent class to correctly describe the stacking behavior of child class +`X11ScreenOzone`. This change also updates the implementation of +`WaylandScreen` to a stacking version. Lastly, this change updates the +call sites of `PlatformScreen` according to the API change. + +[1] https://crsrc.org/c/ui/ozone/public/platform_screen.h;l=96 +[2] https://linux.die.net/man/3/xscreensaverunsetattributes + +Bug: b:193670013 +Bug: b:196213351 +Bug: 1329573 +Bug: 1339361 +Change-Id: I60975c8da9f86a0f26f3c32cf49c4a7eeeea6a12 +Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3759067 +Commit-Queue: Andrew Wolfers <aswolf...@chromium.org> +Reviewed-by: Thomas Anderson <thomasander...@chromium.org> +Reviewed-by: Scott Violet <s...@chromium.org> +Cr-Commit-Position: refs/heads/main@{#1025717} + +(cherry picked from commit e61f08f8dbf1ec7cead427f3c497934e9d0db35f) +--- + ui/aura/screen_ozone.cc | 14 ++++++-- + ui/aura/screen_ozone.h | 29 ++++++++++++---- + ui/base/x/x11_util.h | 4 ++- + ui/display/screen.cc | 21 ++---------- + ui/display/screen.h | 34 ++++++------------- + .../platform/wayland/host/wayland_screen.cc | 31 +++++++++++++++++ + .../platform/wayland/host/wayland_screen.h | 30 +++++++++++++++- + ui/ozone/platform/x11/x11_screen_ozone.cc | 27 +++++++++++++-- + ui/ozone/platform/x11/x11_screen_ozone.h | 19 ++++++++++- + ui/ozone/public/platform_screen.cc | 8 +++-- + ui/ozone/public/platform_screen.h | 26 +++++++++++--- + 11 files changed, 182 insertions(+), 61 deletions(-) + +diff --git a/ui/aura/screen_ozone.cc b/ui/aura/screen_ozone.cc +index a78a6a48f1..09f62dc982 100644 +--- a/ui/aura/screen_ozone.cc ++++ b/ui/aura/screen_ozone.cc +@@ -4,6 +4,8 @@ + + #include "ui/aura/screen_ozone.h" + ++#include <memory> ++ + #include "ui/aura/client/screen_position_client.h" + #include "ui/aura/window.h" + #include "ui/aura/window_tree_host.h" +@@ -108,8 +110,16 @@ display::Display ScreenOzone::GetPrimaryDisplay() const { + } + + #if BUILDFLAG(IS_CHROMEOS_LACROS) || BUILDFLAG(IS_LINUX) +-bool ScreenOzone::SetScreenSaverSuspended(bool suspend) { +- return platform_screen_->SetScreenSaverSuspended(suspend); ++ScreenOzone::ScreenSaverSuspenderOzone::ScreenSaverSuspenderOzone( ++ std::unique_ptr<ui::PlatformScreen::PlatformScreenSaverSuspender> suspender) ++ : suspender_(std::move(suspender)) {} ++ ++ScreenOzone::ScreenSaverSuspenderOzone::~ScreenSaverSuspenderOzone() = default; ++ ++std::unique_ptr<display::Screen::ScreenSaverSuspender> ++ScreenOzone::SuspendScreenSaver() { ++ return std::make_unique<ScreenSaverSuspenderOzone>( ++ platform_screen_->SuspendScreenSaver()); + } + #endif // BUILDFLAG(IS_CHROMEOS_LACROS) || BUILDFLAG(IS_LINUX) + +diff --git a/ui/aura/screen_ozone.h b/ui/aura/screen_ozone.h +index 2970a0e0e7..d033abf366 100644 +--- a/ui/aura/screen_ozone.h ++++ b/ui/aura/screen_ozone.h +@@ -11,10 +11,7 @@ + #include "build/chromeos_buildflags.h" + #include "ui/aura/aura_export.h" + #include "ui/display/screen.h" +- +-namespace ui { +-class PlatformScreen; +-} ++#include "ui/ozone/public/platform_screen.h" + + namespace aura { + +@@ -48,6 +45,10 @@ class AURA_EXPORT ScreenOzone : public display::Screen { + display::Display GetDisplayMatching( + const gfx::Rect& match_rect) const override; + display::Display GetPrimaryDisplay() const override; ++#if BUILDFLAG(IS_CHROMEOS_LACROS) || BUILDFLAG(IS_LINUX) ++ std::unique_ptr<display::Screen::ScreenSaverSuspender> SuspendScreenSaver() ++ override; ++#endif // BUILDFLAG(IS_CHROMEOS_LACROS) || BUILDFLAG(IS_LINUX) + bool IsScreenSaverActive() const override; + base::TimeDelta CalculateIdleTime() const override; + void AddObserver(display::DisplayObserver* observer) override; +@@ -65,11 +66,27 @@ class AURA_EXPORT ScreenOzone : public display::Screen { + protected: + ui::PlatformScreen* platform_screen() { return platform_screen_.get(); } + ++ private: + #if BUILDFLAG(IS_CHROMEOS_LACROS) || BUILDFLAG(IS_LINUX) +- bool SetScreenSaverSuspended(bool suspend) override; ++ class ScreenSaverSuspenderOzone ++ : public display::Screen::ScreenSaverSuspender { ++ public: ++ explicit ScreenSaverSuspenderOzone( ++ std::unique_ptr<ui::PlatformScreen::PlatformScreenSaverSuspender> ++ suspender); ++ ++ ScreenSaverSuspenderOzone(const ScreenSaverSuspenderOzone&) = delete; ++ ScreenSaverSuspenderOzone& operator=(const ScreenSaverSuspenderOzone&) = ++ delete; ++ ++ ~ScreenSaverSuspenderOzone() override; ++ ++ private: ++ std::unique_ptr<ui::PlatformScreen::PlatformScreenSaverSuspender> ++ suspender_; ++ }; + #endif // BUILDFLAG(IS_CHROMEOS_LACROS) || BUILDFLAG(IS_LINUX) + +- private: + gfx::AcceleratedWidget GetAcceleratedWidgetForWindow( + aura::Window* window) const; + +diff --git a/ui/base/x/x11_util.h b/ui/base/x/x11_util.h +index bf36efe170..0692571582 100644 +--- a/ui/base/x/x11_util.h ++++ b/ui/base/x/x11_util.h +@@ -337,7 +337,9 @@ COMPONENT_EXPORT(UI_BASE_X) bool IsCompositingManagerPresent(); + COMPONENT_EXPORT(UI_BASE_X) bool IsX11WindowFullScreen(x11::Window window); + + // Suspends or resumes the X screen saver, and returns whether the operation was +-// successful.
