Previously getTextFromBoxes would just pass the first and last three
bytes of the current and previous words when trying to detect CJK
characters (which shouldn't have spaces inserted).
However, this handling was not correct because CJK characters can be
longer than 3 bytes, and internally BaseUtil.utf8charcode doesn't ensure
that it was only given a single utf8 character (it blindly does the bit
operations on whatever length code you give it).
As a result, before this patch selections in PDF documents would have
lots of spaces stripped because getTextFromBoxes would think that almost
all characters were CJK characters.
Fixes: 6f1b70e5eb ("util.utf8: improve CJK character detection")

The second argument is a ddjvu_render_mode_t
Try to actually honor the user settings instead of enforcing COLOR
while we're there.
Fix#8376
Regression since #8250
There were a handful of cases where if there was no cached kctx there
was no fallback and several KoptInterface methods would return nil,
causing issues in various parts of KOReader (this happened with the
migration to selected_text everywhere but it's unclear how that change
caused this regression).
In any case, from a correctness perspective it makes sense to have the
corresponding fallback paths to create a new kctx if we couldn't find a
cached one.

With the latest koreader-base update, we can now create native
selections using getTextFromXPointers. In order to make the wrapper less
annoying to use, always enable segmented selection if selections are
enabled (to match getTextFromPositions).

It is a bit cleaner to do all of the necessary looping over lists of
Geoms within a straight-forward Geom.boundingBox function rather than
looping over :combine every time (or reimplementing :combine in some
cases). Geom:combine can be trivially reimplemented in terms of
Geom.boundingBox as well.

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).
* Geom:transformByScale:
* Apply the right scaling factor to the y axis
* Round in a more sensible fashion (àla fz_round_rect, since we pretty much exclusively use it in a similar fashion).
* Bump base (https://github.com/koreader/koreader-base/pull/1407)
TileCacheItem: add created_ts property.
Document: manage a tile_cache_validity_ts and ignore
older cached tiles.
This timestamps is updated when highlights are written
as annotations in, or deleted from, the PDF, so we can
get the most current rendered bitmap from MuPDF and
avoid highlight ghosts on old tiles.
Save this timestamp in doc settings so older cached to
disk tiles will also be ignored across re-openings.
Bump base for: mupdf.lua: update frontend pboxes with
MuPDF adjusted ones.
We may get multiple boxes when selecting texts, one for each
word, and we have to add spaces between the extracted words
ourselves. Previously, we were only adding a space if the
last char of previous word was ASCII, so missing spaces
after accents or greek words.
Try to do better by measuring the distances between boxes
and comparing to box heights, with a few heuristics.
Bump base for cre.cpp cleanup and utf8proc FFI.
Add a checkbutton for case sensitive search in FileBrowser,
and use Utf8Proc.lowercase() for case insensitive search.
Also use it in ReaderUserHyph as a replacement for
crengine getLowercasedWord().
- bump crengine: findText(): add support for regular
expression search.
- bump base: add thirdparty/srell/srell.hpp, a C++ library
that provides Unicode regex support, used by crengine.
- ReaderSearch: with credocuments, add checkboxes for case
sensitive and regular expression search.
I've encountered an issue when Calibre Content Server's OPDS feed produced ``text/fb2-xml`` mimetype. Don't know if it is actually Calibre to blame, but thought this simple fix will save some poor souls' time.
get any boxes
Exposed by #7624, but we were arguably putting garbage in the Cache
before that anyway, so, it w<asn't all that great either ;p.
Fix#7850
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.
It can happen in perfectly sane contexts.
CReDocument: Don't destroy internal engine data when Document just
decreased the refcount (as opposed to actually tore down the document
userdata if it were the last ref).
PdfDocument: Only write edited documents if the Doc instance was torn
down.
PicDocument: Silence some DocumentRegistry related warnings
Use a table & table.concat instead of individual concats.
And then use that same table for every hash-related operation.
(Nothing else uses the configurable hash function, otherwise I'd have
limited the table shenanigans to the function itself).
* Allow doing away with CacheItem
Now that we have working FFI finalizers on BBs, it's mostly useless overhead.
We only keep it for DocCache, because it's slightly larger, and memory pressure might put us in a do or die situation where waiting for the GC might mean an OOM kill.
* Expose's LRU slot-only mode
And use it for CatalogCache, which doesn't care about storage space
* Make GlyphCache slots only (storage space is insignificant here, it was
always going to be evicted by running out of slots).
* More informative warning when we chop the cache in half
* Neuter timekeeping when statistics are disabled
Saves a few syscalls ;).
* Port to ffi/lru
Only a tiny bit of it actually requires any sort of LRU logic, so it's fairly painless.
* Release the cache on close
* Use string.buffer to serialize function arguments
Ought to be faster than the custom approach ;).
(Still requires wrapping them in a table, though).
It's much less human-readable, but then again, this doesn't need to be :).
Ought to be faster than our naive array-based approach.
Especially for the glyph cache, which has a solid amount of elements,
and is mostly cache hits.
(There are few things worse for performance in Lua than
table.remove @ !tail and table.insert @ !tail, which this was full of :/).
DocCache: New module that's now an actual Cache instance instead of a
weird hack. Replaces "Cache" (the instance) as used across Document &
co.
Only Cache instance with on-disk persistence.
ImageCache: Update to new Cache.
GlyphCache: Update to new Cache.
Also, actually free glyph bbs on eviction.
* Minor updates to the min & max cache sizes (16 & 64MB). Mostly to satisfy my power-of-two OCD.
* Purge broken on-disk cache files
* Optimize free RAM computations
* Start dropping LRU items when running low on memory before pre-rendring (hinting) pages in non-reflowable documents.
* Make serialize dump the most recently *displayed* page, as the actual MRU item is the most recently *hinted* page, not the current one.
* Use more accurate item size estimations across the whole codebase.
TileCacheItem:
* Drop lua-serialize in favor of Persist.
KoptInterface:
* Drop lua-serialize in favor of Persist.
* Make KOPTContext caching actually work by ensuring its hash is stable.

* LuaSettings/DocSettings: Updated readSetting API to allow proper initialization to default.
Use it to initialize tables, e.g., fixing corner-cases in readerFooter that could prevent settings from being saved.
(Fixes an issue reported on Gitter).
* LuaSettings/DocSettings: Add simpler API than the the flip* ones to toggle boolean settings.
* Update LuaSettings/DocSettigns usage throughout the codebase to use the dedicated boolean methods wher appropriate, and clean up some of the more mind-bending uses.
* FileChooser: Implement an extended default exclusion list (fix#2360)
* ScreenSaver: Refactor to avoid the pile of kludges this was threatening to become. Code should be easier to follow and use, and fallbacks now behave as expected (fix#4418).
Rework Dual pages code so that the view is considered
a single page number, so it looks more like 2-columns
on a single page.
This solves a few issues like:
- Page number and count are consistent between top
and bottom status bars
- SkimTo -1/+1 doing nothing every other tap
- Statistics being wrong (like "Pages read" never
going over half of the book page count)
Drop the use of crengine's getWordFromPosition() which
is a bit unreliable: it may returns wrong coordinates,
or words from far away in the book (ie. when holding
in the margins).
Rely only on the robust getTextFromPositions() that
we already use for multi words selection.
Having good coordinates allows refreshing a smaller region
(the higlighted word, or the 2 lines if hyphenated).
* stride is now a size_t
On some platforms, that's 64 bits, which means it's no longer
automatically converted to a Lua number to avoid precision loss.
Do that ourselves, because lua-serialize doesn't know how to handle an
uint64_t cdata ;).
- Move zoom options from top menu to bottom config
- Add option to manually define zoom (relative to
page width) and overlap (in percent)
- Add options to zoom to columns or rows, possibly
with overlap. Add panning direction options when
page forward in these modes
Add option to hide (skip) non-linear fragments, only working
in 1-page mode. Tweaks mostly to footer, toc and skim code
to make it clear(er) which pages belong to linear or non-linear
fragments.
