* translation text fix
* quickstart(fix): go back to home dir after document close
* quickstart(fix): purge old quick start files
* spec: fix quickstart tests
Travis only makes a shallow clone of --depth=50. KOReader is small enough that we can just grab it all. This is necessary to generate the version number, without which some tests will fail.
I'm not entirely sure why something like `git fetch origin master tags/v2015.11` doesn't do the trick, but it doesn't matter much.
* Travis: speed up by caching base and running luacheck earlier
* ignore bin and install for git status change detection
* skip coverage except on official master branch. It adds 3 whole minutes and does nothing to prevent regressions
* also cache ~/.luarocks. It evens out but would generally prevent remote timeout shenenigans
* remove base cache dir before caching with verbose remove to see what's going on
* more inclusive shell code quality analysis
* fixed more shellcheck issues
* better shellcheck/shfmt debugging info
and have more confidence with the unit testing framework.
Now `make testfront` won't retry on failure and testing files are
ordered in each run so that it's possible to reproduce testing failure.
And this patch also fix flush settings not working before suspend issue:
at some point the `FlushSettings` event is sent to `UIManager` instead
of `ReaderUI`, but `UIManager` only delegated events to active widgets
and `ReaderUI` is actually not an active widgets thus will miss the event.
This patch also add a verbose debug mode with "-v" as a switch to turn
on this mode. With verbose mode on, event handling will be logged.
1. It turns out that `device_id` is not defined in unit test environment
which makes the `assert(self.kosync_device_id)` fail and somehow makes `luajit` segmentation fault.
2. In the device spec, stubbing `io.open` will make subsquent `require`
all return boolean value and segmentation fault `luajit`.
This patch is a minimum viable change that makes CI work on both my
local box and Travis.
