We should always unschedule suspend before scheduling it again (i.e.,
use rescheduleSuspend ;)).
Fix#8097 (many thanks to @Mel-kior for the detailed repro!)
It turns out that the kernel needs a little push now that the dedicated
wifi power control module is gone ;).
Issue was only exposed if you booted KOReader while the Wi-Fi was down.
* Decode EV_KEY:KEY_BATTERY
* Input: Only drop hovering *pen* events.
There are currently too many broken 0-pressure *finger* events being
reported on the Elipsa, making a dumb rejection highly annoying.
* Bump base
https://github.com/koreader/koreader-base/pull/1393
* Rely on actual events to detect loss of contact for the "snow"
protocol.
Allows simplifying the whole thing.
* Use `ipairs` over `pairs` for pure arrays.
The hyphenation of a word can be changed from its default
by long pressing for 3 seconds and selecting 'Hyphenate'.
These overrides are stored in a per-language file, i.e:
koreader/settings/user-German.hyph.
Notification: adds some functions so it can be used as
a notification manager.
Have various bits of code emitting events that may generate
notifications advertize themselves as the source for following
notifications.
Add a menu to allow selecting some subsets of sources
to show or hide.
Add a new reader module: ReaderScrolling, that exposes
some Scrolling options to the menu (which are to be used
by and implemented in ReaderPaging and ReaderRolling
themselves) and implement some inertial scrolling logic
used by both of them.
Default to "Classic scrolling" which is the expected
behaviour on phones and tablets.
The old CreDocument buggy behaviour is available as
"Turbo scrolling" for both Paging and Rolling documents.
Added a "On release scrolling" option that might be
useful on eInk to avoid dynamic pan/scrolling.
Try to avoid bad interactions between pan and swipe,
cancelling unwanted panning if we ended up doing a
swipe or multiswipe.
We've managed to trip a few of those on dimen fields post-init but
pre-paintTo in a few weird coner-cases, a point at which dimen is often
nil.
ConfigDialog: Deal with that very thing in update()
Fix#7656
* Input: Don't create a new TimeVal object for input frame timestamps, just promote our existing table by assigning it the `TimeVal` metatable.
* TimeVal: Export (const) `zero` & `huge` TimeVal objects, because they're common enough in our codebase. (NOTE: not actually const, that's a Lua 5.4 feature ;p).
* GestureDetector: Explain the behavior of the `last_tevs` & `first_tevs` tables, and why one needs a new object and not the other.
* Speaking of, simplify the copy method for `first_tevs`, because it doesn't need to create a new TimeVal object, we can just reference the original, it's unique and re-assigned for each frame.
* TimeVal: Log the results of the COARSE probes in debug logs
* GestureDetector: Print details of failed clock probes in debug logs
* GestureDetector: Skip the BOOTTIME probe when CLOCK_BOOTTIME is unsupported.
* Input: Decode ABS_DISTANCE events in debug logs
* Get rid of duplicated <linux/input.h> constants, use the FFI module everywhere (re #7536)
* Kobo: Get rid of the `touch_alyssum_protocol` quirk. Replace it by setting `main_finger_slot` to `1`, like on the H2O.
The Wacom pen reports sane CLOCK_REALTIME timestamps, but the Touchscreen reports timestamps frozen at the boot time ts (in REALTIME) :s.
So, make everyone use synthetic CLOCK_MONOTONIC timestamps in order to make gesture detection behave.
Requires https://github.com/koreader/koreader-base/pull/1344 & https://github.com/koreader/koreader-base/pull/1346 (fix#7485)
Assorted input fixes:
* Actually handle errors in the "there's a callback timer" input polling loop.
* Don't break timerfd when the clock probe was inconclusive.
Not directly related, but noticed because of duplicate onInputEvent handlers:
* HookContainer: Fix deregistration to actually deregister properly. "Regression" extant since its inception in #2933 (!).
* Made sure the three plugins (basically the trio of AutoThingies ;p) that were using HookContainer actually unschedule their task on teardown.
* Actually load librt properly on old Linux systems (fix#7472)
* Made sure SDL & Android honored timeouts properly in some edgy (or not so edgy, in SDL's case) cases (c.f., https://github.com/koreader/koreader-base/pull/1343).
* Try harder not to consume a timer callback when the timerfd backend is in use and `select` timed out *not* because of a timerfd expiring. This would take some particularly heinous timing to reproduce (e.g., a timerfd set, but a task deadline expiring *before* it). May or may not help with #7473.
* Decode `BTN_` KEY codes in verbose debug logs.
* Fix MultiTouch on the H2O (GestureDetector was hard-coding the two slots as 0 & 1, but the H2O kernel is a special snowflake that doesn't use slot 0, instead switching to slot 1 & 2).
* ReaderDictionary: Port delay computations to TimeVal
* ReaderHighlight: Port delay computations to TimeVal
* ReaderView: Port delay computations to TimeVal
* Android: Reset gesture detection state on APP_CMD_TERM_WINDOW.
This prevents potentially being stuck in bogus gesture states when switching apps.
* GestureDetector:
* Port delay computations to TimeVal
* Fixed delay computations to handle time warps (large and negative deltas).
* Simplified timed callback handling to invalidate timers much earlier, preventing accumulating useless timers that no longer have any chance of ever detecting a gesture.
* Fixed state clearing to handle the actual effective slots, instead of hard-coding slot 0 & slot 1.
* Simplified timed callback handling in general, and added support for a timerfd backend for better performance and accuracy.
* The improved timed callback handling allows us to detect and honor (as much as possible) the three possible clock sources usable by Linux evdev events.
The only case where synthetic timestamps are used (and that only to handle timed callbacks) is limited to non-timerfd platforms where input events use
a clock source that is *NOT* MONOTONIC.
AFAICT, that's pretty much... PocketBook, and that's it?
* Input:
* Use the <linux/input.h> FFI module instead of re-declaring every constant
* Fixed (verbose) debug logging of input events to actually translate said constants properly.
* Completely reset gesture detection state on suspend. This should prevent bogus gesture detection on resume.
* Refactored the waitEvent loop to make it easier to comprehend (hopefully) and much more efficient.
Of specific note, it no longer does a crazy select spam every 100µs, instead computing and relying on sane timeouts,
as afforded by switching the UI event/input loop to the MONOTONIC time base, and the refactored timed callbacks in GestureDetector.
* reMarkable: Stopped enforcing synthetic timestamps on input events, as it should no longer be necessary.
* TimeVal:
* Refactored and simplified, especially as far as metamethods are concerned (based on <bsd/sys/time.h>).
* Added a host of new methods to query the various POSIX clock sources, and made :now default to MONOTONIC.
* Removed the debug guard in __sub, as time going backwards can be a perfectly normal occurrence.
* New methods:
* Clock sources: :realtime, :monotonic, :monotonic_coarse, :realtime_coarse, :boottime
* Utility: :tonumber, :tousecs, :tomsecs, :fromnumber, :isPositive, :isZero
* UIManager:
* Ported event loop & scheduling to TimeVal, and switched to the MONOTONIC time base.
This ensures reliable and consistent scheduling, as time is ensured never to go backwards.
* Added a :getTime() method, that returns a cached TimeVal:now(), updated at the top of every UI frame.
It's used throughout the codebase to cadge a syscall in circumstances where we are guaranteed that a syscall would return a mostly identical value,
because very few time has passed.
The only code left that does live syscalls does it because it's actually necessary for accuracy,
and the only code left that does that in a REALTIME time base is code that *actually* deals with calendar time (e.g., Statistics).
* DictQuickLookup: Port delay computations to TimeVal
* FootNoteWidget: Port delay computations to TimeVal
* HTMLBoxWidget: Port delay computations to TimeVal
* Notification: Port delay computations to TimeVal
* TextBoxWidget: Port delay computations to TimeVal
* AutoSuspend: Port to TimeVal
* AutoTurn:
* Fix it so that settings are actually honored.
* Port to TimeVal
* BackgroundRunner: Port to TimeVal
* Calibre: Port benchmarking code to TimeVal
* BookInfoManager: Removed unnecessary yield in the metadata extraction subprocess now that subprocesses get scheduled properly.
* All in all, these changes reduced the CPU cost of a single tap by a factor of ten (!), and got rid of an insane amount of weird poll/wakeup cycles that must have been hell on CPU schedulers and batteries..
* Re-implement the PB fb fixup insanity
It's apparently still necessary on a number of devices.
Fix#7072
* Bump base
(Fix FBInk on the same devices, for another reason).
