* Don't run multiple collectSubprocesses tasks in parallel.
UIManager:scheduleIn doesn't return anything, using that as a boolean trap made no sense.
* Make the in-place removal of collected pids use a slightly more common idiom
(table.remove in a reverse iteration of said array).
cores
* Only keep a single core online most of the time.
* Device: Add an enableCPUCores method to allow controlling the amount of
online CPU cores.
* Move the initial core onlining setup to Kobo:init, instead of the startup script.
* Enable two CPU cores while hinting new (e.g., cache miss) pages in PDF land.
* Enable two CPU cores while processing book metadata.
* Drive-by fix to isolate the DocCache pressure check to KoptInterface
and actually apply it when it matters most (e.g., k2pdfopt stuff).
* Fix XML, introduce some better error messages, etc.
See roygbyte/newsdownloader.koplugin for more info
* Fix feed attribute saving snafu; Change menu labels; etc.
Also:
- Change default feed
- Change "remove" label to "delete"
- Hide menu after feed sync
* Add comments to a few functions
* Fix bug associated with arxiv catalog.
See comments in genItemTableFromCatalog. Basically, though, the bug
was related to the checking of the acquisition urls. Arxiv only has
PDFs available to download, and the block wasn't catching these with
its existing logic. By adding another clause to look for PDF link
types, and fixing href values that were missing the PDF suffix, we can
successfully download PDFs from Arxiv.
* Gestures: standardize hold to long-press
* Common settings menu: standardize hold to long-press
* Readerstyletweak: standardize hold to long-press
* Readersearch: standardize hold to long-press
* Cleanup util.secondsFrom*Clock stuff (simpler maths, tail calls, meaningful printf tokens).
* Use util.secondsToClockDuration in ReadTimer instead of reinventing the wheel three different ways.
* Reschedule unexpired timers properly on resume (as best as we can, given the unreliable nature of REALTIME).
* Make clock timers tick on the dot, instead of at the same second as when being set.
* Speaking of clock timers, leave the math to os.date & os.time, don't reinvent the wheel yet again.
Add the possibility to autostart profiles when KOReader is started with filemanager or lastfile.
Discussed in #8020
If more profiles are selected, they are started in alphabetically order.
OPDS catalog can be invoked from reader with gesture.
Then on closing OPDS catalog, KOReader crashes.
Let's jump to the download folder instead.
Closes#7784.
