* 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.
* Revamped most actions that require an internet connection to a new/fixed backend that allows forwarding the initial action and running it automatically once connected. (i.e., it'll allow you to set "Action when Wi-Fi is off" to "turn_on", and whatch stuff connect and do what you wanted automatically without having to re-click anywhere instead of showing you a Wi-Fi prompt and then not doing anything without any other feedback).
* Speaking of, fixed the "turn_on" beforeWifi action to, well, actually work. It's no longer marked as experimental.
* Consistently use "Wi-Fi" everywhere.
* On Kobo/Cervantes/Sony, implemented a "Kill Wi-Fi connection when inactive" system that will automatically disconnect from Wi-Fi after sustained *network* inactivity (i.e., you can keep reading, it'll eventually turn off on its own). This should be smart and flexible enough not to murder Wi-Fi while you need it, while still not keeping it uselessly on and murdering your battery.
(i.e., enable that + turn Wi-Fi on when off and enjoy never having to bother about Wi-Fi ever again).
* Made sending `NetworkConnected` / `NetworkDisconnected` events consistent (they were only being sent... sometimes, which made relying on 'em somewhat problematic).
* restoreWifiAsync is now only run when really needed (i.e., we no longer stomp on an existing working connection just for the hell of it).
* We no longer attempt to kill a bogus non-existent Wi-Fi connection when going to suspend, we only do it when it's actually needed.
* Every method of enabling Wi-Fi will now properly tear down Wi-Fi on failure, instead of leaving it in an undefined state.
* Fixed an issue in the fancy crash screen on Kobo/reMarkable that could sometime lead to the log excerpt being missing.
* Worked-around a number of sneaky issues related to low-level Wi-Fi/DHCP/DNS handling on Kobo (see the lengthy comments [below](https://github.com/koreader/koreader/pull/6424#issuecomment-663881059) for details). Fix#6421
Incidentally, this should also fix the inconsistencies experienced re: Wi-Fi behavior in Nickel when toggling between KOReader and Nickel (use NM/KFMon, and run a current FW for best results).
* For developers, this involves various cleanups around NetworkMgr and NetworkListener. Documentation is in-line, above the concerned functions.
Simplify (and avoid edge cases) in other code by having
ReadHistory manage the "lastfile" setting on add, remove,
rename...
Fixed a few other cases of things not updated.
bidi.lua:
- Revert "Alias everything to Bidi.nowrap() when in LTR UI,
as using LTR isolates seems uneeded when already LTR" (part
of a628714f) which was a wrong assumption: we need proper
wrappers for all things paths. Enhance some of these wrappers.
- Fix GetText RTL wrapping which was losing empty lines and
trailing \n.
- Wrap all paths, directories, filenames in the code with
these wrappers.
- Wrap all book metadata (title, authors...) with BD.auto(),
as it helps fixing some edge cases (like open/close quotation
marks which are not considered as bracket types by FriBiDi).
(Needed some minor logic changes in CoverBrowser.)
- Tweak hyphenation menu text
- Update forgotten SortWidget for UI mirroring
- KoptConfig: update "justification" index for RTL re-ordering,
following the recent addition of the page_gap_height option.
A new setting has been adding allowing to set a comma separated list of
tags to ignore.
Entries with either of these tags will be skipped by the client when
fetching the list of articles to download. Extra articles will be
fetched from the server to make up for the skipped articles, ensuring to
meet the target number of articles.
Currently, all the articles were converted to .epub by default. When
handling an article that linked to a .pdf file, it resulted in an
unreadable file.
This patch skips the conversion for a pdf file, and download it directly
instead.
This commit standardizes the various todos around the code a bit in a manner recognized by LDoc.
Besides drawing more attention by being displayed in the developer docs, they're also extractable with LDoc on the command line:
```sh
ldoc --tags todo,fixme *.lua
```
However, whether that particular usage offers any advantage over other search tools is questionable at best.
* and some random beautification
Revert 9971eb85 and make multi-lines strings more readable.
(Multiline translatable strings extraction has been fixed
in koreader-misc tralua_xgettext.py.)
The Wallabag plugin's callAPI() method was attempting to parse the user supplied
URL for the Wallabag API. Unfortunately, the parse was silently failing since
the variable apiurl did not contain a complete URL. The scheme of the parsed
URL (always nil) was then used to select either http or https (default). The
result being https was always selected, regardless of the user supplied setting.
The parsed URL was switched to the variable server_url instead of apiurl but the
behavior resulting in the default selection of https when parsing fails was left
unchanged.
Previously the plugin was creating JSON by hand for authentication requests.
This would cause invalid JSON to be sent when the password contained characters
that need to be escaped (e.g. "). Using JSON.encode will result in values being
properly escaped when necessary.
