I've found that some OPDS catalogs have multiple downloads of the same filetype, but optimized or formatted in different ways. The Title of the download is much more descriptive in this case, so I thought it would be better to display the title if available.
The OPDS catalog at https://standardebooks.org/opds is a good example. Note how entries in https://standardebooks.org/opds/new-releases have three different epub downloads, titled "Recommended compatible epub", "Advanced epub", and "Kobo Kepub epub".
* 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.
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.
* 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
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.
There have been a couple of these this month, and keeping stuff that should only ever run once piling up in their respective module was getting ugly, especially when it's usually simple stuff (settings, files).
So, move everything to a dedicated module, run by reader.lua on startup, and that will actually only do things once, when necessary.
* Change 'Find a file' to 'File search' for consistency
There is 'File search' in the Gesture manager already.
There is 'Fulltext search' in the readermenu.
Some help text added.
* Add a new socketutil module with a few helper functions that allow us to:
* Always use a sane User-Agent (previously, only Wikipedia did so)
* Set timeouts in an almost sane manner. Doing it explicitly prevents an interaction with KOSync that does crazy stuff I don't even want to try to understand.
* Unified said timeouts based on the request's intended usage (except for Wikipedia, which already had meaningful timeout values).
* Stopped using LuaSec directly, LuaSocket defers to LuaSec sanely on its own. Everything now transparently supports HTTPS without code duplication.
* 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).
* OPDS: Don't save an empty username.
That causes LuaSockets to try Basic auth, which is useless (and may or may not be problematic for some servers).
* Attempt to explicitly request non-compressed content.
Some servers may still refuse to obey, though.
They're breaking RFC2616 (a.k.a. HTTP/1.1) by doing so, though, meh.
* Let LuaSocket do its job.
It already handles setting up the Host header, as well as Basic authentication if both username & password are set.
Remember, it's life +70 in US & EU, life +50 is Canada.
(It's actually slightly more complex than that, and some periods of
time/countries may use a far longer term. IANAL).
