* Kobo: Switch ST devices to a dedicated input handler
Instead of shoehorning a hack into the standard handler.
* Use setCurrentMtSlotChecked in handleTouchEvLegacy
slots
This ensures we won't leave *any* slot in an undefined state because
we skipped parsing 'em because what we consumed first yielded a
gesture.
(In particular, this could leave a few slots dangling in the "hold"
state in corner cases involving spider-hand finger tapping ;p).
Cleans up the slot state clearing in GestureDetector to only clear the
necessary slots (e.g., two-finger gestures now only clear their own two
slots; and holds only clear their own slot).
The fact that every slot will be consumed ensures that every slot will
naturally get their contact up handled, which wasn't the case before,
hence those crappy workarounds.
As far as timerfd callbacks are concerned, this *does* introduce the
possibility of deadline collisions, so, do reimplement minimal safety
checks to ensure we run (and free) the right timerfd callback.
Some drivers can bundle the same slot multiple times in the same input
frame. We were only correctly coalescing *consecutive* slots, but some
drivers can do that in non-consecutive sequences (e.g., 1a -> 2a -> 1b
-> 2b), so, handle that, too.
Seen on neonode v2 grids.
Make sure we always create the storage table when we add its reference
to the MTSlots list instead.
(The reasoning being we only add the reference once, and it's the first
thing we do, and we kinda need the storage to be created to get its
reference anyway; while we may set multiple keys per frame).
For realz, this time.
This reverts the original attempt, because it was gratuitous
overcomplexification that turns out to be completely unnecessary.
This also fixes a few subtle MT handling snafus on some devices.
We'll only honor one (the last one) anyway, and we've already cleared
the timers, so the others are essentially lost and stuck in limbo.
(Repro: do a series of staggered holds on different words with different
fingers in a CRe document; the one that'll "take" is the last one,
but *every* slot will be stuck in a hold state, which can essentially
semi lock you into broken input until you manage to clear the right
slots by doing duplicate multi-slot holds again...).
Multitouch gestures can create multiple timers on the same deadline, but
on different slots, so simply hoping that the head of the list would
match was somewhat optimistic... ;o).
Fix#9376
It's trickier in the !timerfd case, though,
so do the best we can there...
(It wouldn't crash, but it might fire the "wrong" callback).
In some versions of the /ebrmain/config/extensions.cfg file there is a
comment #ebrcfg. This will not match the regex and crashes koreader as
the table is empty.
Add a check to ensure the table is not empty while reading extensions
from the default file.
This is useful for the sysstat plugin not to have 00:00 for suspend time :)
Something similar should probably be done for the other canSuspend platforms.
* AutoSuspend: Use the canSuspend devcap check instead of reinventing the wheel.
* Device & UIManager: Cleanup canSuspend devcap check related stuff to avoid boilerplate code.
(It also now defaults to no, and is explicitly set by device implementations where supported).
* AutoSuspend: Re-engage suspend/shutdown timers when fully charged.
This restores the existing behavior pre #9036
(c.f., https://github.com/koreader/koreader/pull/9258#issuecomment-1167672356)
* SDL: Unbreak the fake suspend behavior so that it actually works.
Tweak the default screensaver message to remind users that Power is bound to F2.
(Fix#9262)
* AutoSuspend: Re-engage suspend/shutdown timers on unplug.
This matters on Kobo, because the unexpected wakeup guard might have stopped the suspend timer.
Schedule wifi keep-alive on wifi start but do not reschedule when
connection is lost. This will make sure this code is not run when
wifi is disabled again saving some battery and cpu cycles.
Commonize fullscreen code across different devices.
Add fullscreen toggle on SDL desktop targets.
Expose the toggle to the dispatcher and map it to F11.
Hide touchmenu when resizing.
* GestureDetector: Downgrade probeClockSource log messages to debug
We're seeing a bit more of 'em between autostandby and inhibitInput now,
and the whole thing was implemented long enough ago that it's no longer
critical to see this in random non-debug logs ;).
* Input: Reset gesture state in inhibitInput
Should prevent bogus gestures when re-enabling the handlers if we were
called in the middle of gesture detection.
Long story short: the LeaveStandby event is sent via `tickAfterNext`, so if we tear down the plugin right after calling it (in this case, that means that the very input event that wakes the device up from suspend is one that kills ReaderUI or FileManager), what's in UIManager's task queue isn't the actual function, but the anonymous nextTick wrapper constructed by `tickAfterNext` (c.f.,
https://github.com/koreader/koreader/issues/9112#issuecomment-1133999385).
Tweak `UIManager:tickAfterNext` to return a reference to said wrapper, so that we can store it and unschedule that one, too, in `AutoSuspend:onCloseWidget`.
Fix#9112 (many thanks to [@boredhominid](https://github.com/boredhominid) for his help in finding a repro for this ;)).
Re: #8638, as the extra debugging facilities (i.e., ebb81b9845) added during testing might help pinpoint the root issue for that one, too.
Also includes a minor simplification to `UIManager:_checkTasks`, and various other task queue related codepaths (e.g., `WakeupMgr`) ;).
The change from timeval to time completely broke reMarkable.
frontend/device/remarkable/device.lua was using TimeVal:now() to manually overwrite event time values, as noted in the code comments.
Input:handleTouchEv is expecting those event time values to be timevals, not integer times.
So as soon as the user touches the screen, crash.
* Disable all non power management related input during suspend. (This prevents wonky touch events from being tripped when closing a sleep cover on an already-in-suspend device, among other things).
* Kobo: Use our WakeupMgr instance, not the class.
* WakupMgr: split `removeTask` in two:
* `removeTask`, which *only* takes a queue index as input, and only removes a single task. Greatly simplifies the function (i.e., it's just a `table.remove`).
* `removeTasks`, which takes an epoch or a cb ref, and removes *every* task that matches.
* Both of these will also *always* re-schedule the next task (if any) on exit, since we can have multiple WakeupMgr tasks queued, but we can only have a single RTC wake alarm set ;).
* `wakeupAction` now takes a `proximity` argument, which it passes on to its `validateWakeupAlarmByProximity` call, allowing call sites to avoir having to duplicate that call themselves when they want to use a custom proximity window.
* `wakeupAction` now re-schedules the next task (if any) on exit.
* Simplify `Kobo:checkUnexpectedWakeup`, by removing the duplicate `WakerupMgr:validateWakeupAlarmByProximity` call, now that we can pass a proximity window to `WakeuoMgr:wakeupAction`.
* The various network activity timeouts are now halved when autostandby is enabled.
* Autostandby: get rid of the dummy deadline_guard task, as it's no longer necessary since #9009.
* UIManager: The previous change allows us to simplify `getNextTaskTimes` into a simpler `getNextTaskTime` variant, getting rid of a table & a loop.
* ReaderFooter & ReaderHeader: Make sure we only perform a single refresh when exiting standby.
* Kobo: Rewrite sysfs writes to use ANSI C via FFI instead of stdio via Lua, as it obscured some common error cases (e.g., EBUSY on /sys/power/state).
* Kobo: Simplify `suspend`, now that we have sane error handling in sysfs writes.
* Kobo.powerd: Change `isCharging` & `isAuxCharging` behavior to match the behavior of the NTX ioctl (i.e., Charging == Plugged-in). This has the added benefit of making the AutoSuspend checks behave sensibly in the "fully-charged but still plugged in" scenario (because being plugged in is enough to break PM on `!canPowerSaveWhileCharging` devices).
* AutoSuspend: Disable our `AllowStandby` handler when auto standby is disabled, so as to not interfere with other modules using `UIManager:allowStandby` (fix#9038).
* PowerD: Allow platforms to implement `isCharged`, indicating that the battery is full while still plugged in to a power source (battery icon becomes a power plug icon).
* Kobo.powerd: Implement `isCharged`, and kill charging LEDs once battery is full.
* Kindle.powerd: Implement `isCharged` on post-Wario devices. (`isCharging` is still true in that state, as it ought to).
* Make sure AutoStandby cohabitates nicely with AutoSuspend (regression since #8985), specifically:
* Disable standby during suspend.
* Ensure that leaving standby restores the scheduled suspend properly, with the appropriate remaining amount of time based on the last user input.
* Handle devices with an auxiliary battery better when scheduling suspend (assume it's only charging when the aux battery is charging, not the ereader's).
* Tweak debug logging to be able to remote debug corner-cases more easily without requiring code changes.
* Fix erroneous behavior when awoken from standby by something that doesn't trigger an InputEvent Event (e.g., rtc alarm, gyro, or random bullshit).
Specifically, don't forcibly unschedule/schedule on every input event, instead, let the scheduled task figure out if the deadline came to pass or not ;).
c.f., https://github.com/koreader/koreader/pull/8970#issuecomment-1092775830
Besides getting rid of some overhead, this allows proper scheduling after a task that would have blocked for longer than the standby timeout.
* Handle said rotation shenanigans inside ScreenSaver & ScreenSaverWidget, which allows a more targeted approach; and prevents said rotation from affecting other widgets. (Also, gets rid of duplicated code).
* Handle the corner-case or exiting early from a "keep on screen for n sec" screensaver better, by unscheduling the extra refresh, since an early tap took care of that already.
