Includes "set android versionCode and android versionName at buildtime" (<https://github.com/koreader/android-luajit-launcher/pull/106>)
* versionCode uses the number of Git commits, because Google doesn't like values larger than `2100000000`
* versionName uses our existing version string
References #2040.
* Switch all initial highlights to "fast" update
i.e., everything that does an invert
Plus a few other things that refresh small UI elements onTap
Re #3130
* Tweak refreshtype for a number of widgets:
* Fix iconbutton dimen
* Make touchmenu flash on close & initial menu popup. Full-screen on close.
* Use flashing updates when opening/closing dictionary popup. Full-screen on close.
* Switch FileManager to partial.
It's mostly text, and we want flash promotion there.
* Make configdialog & menu flash on exit
* Make FLWidget flash on close
* virtualkeyboard: flash on layout change & popup.
* Potentially not that great workaround to ensure we actually see the
highlights in the FM's chevrons
* Flash when closing BookStatus Widget
* Optimize away a quirk of the dual "fast" update in touchmenu
* Promote updates to flashing slightly more agressively.
* Document what each refreshtype actually does.
With a few guidelines on their optimal usecases.
* Switch remaining scheduleIn(0.0) to nextTick()
* Tighter scheduling timers
Shaving a hundred ms off UI callbacks...
* Cache FFI C Library namespace
* Ask MuPDF to convert pixmaps to BGR on Kobo
Fix#3949
* Mention koxtoolchain in the README
re #3972
* Kindle: Handle *all* fonts via EXT_FONT_DIR instead of bind mounts insanity
* Make black flashes in UI elements user-configurable
(All or nothing).
* Jot down some random KOA2 sysfs path
You'll still have to call it with `ANDROID_ARCH=x86 ./kodev build/release/run android`.
Don't forget to `./mk-luajit.sh clean` in luajit-launcher when changing architectures.
* Bump android-luajit-launcher
This includes the fix for Android 8. Fixes#3126.
* Bump base
Also improve SDK installation for ease of setting up development system.
This also puts in place most of the missing pieces to finish the intent in #3064.
to make koreader on Android more stable
and with these opt params:
```
require("jit.opt").start("sizemcode=64","maxmcode=64", "hotloop=10000")
```
The strategy here is that we only use precious mcode memory (jitting)
on deep loops like the several blitting methods in blitbuffer.lua and
the pixel-copying methods in mupdf.lua. So that a small amount of mcode
memory (64KB) allocated when koreader is launched in the android.lua
is enough for the program and it won't need to jit other parts of lua
code and thus won't allocate mcode memory any more which by our
observation will be harder and harder as we run koreader.
This workaround makes a reservation of mmap slots that are hopefully
near the address of `mcode_alloc_at`. Then it unmaps those slots and
lets luajit allocate a large slot for mcode.
On kindle, kobo and pocketbook the data directory is the current
running directory but on Android the app is installed in system
defined location and users may have no access to that location.
The same circumstances should be true for the upcoming Koreader for
Ubuntu touch, so the data directory (in which tessdata, dictionaries,
global settings, persistant defaults and probably history data are
stored) could be stored in another place.
Anyone who encounters random freeze of koreader for Android
is encouraged to enable this by adding a file at
"/sdcard/koreader/patch.lua" with the content of:
```
require("jit.opt").start("sizemcode=256","maxmcode=256")
for i=1,100 do end -- Force allocation of one large segment
```
The sizemcode and maxmcode could be adjusted from 196 to 512 to
make koreader best fit on your Android device.
