* Add scroll when it edits a line out of viewport
By default, when there is an edition of a line, which is out of the
viewport, Etherpad scrolls the minimum necessary to make this line
visible. This makes that the line stays either on the top or the bottom
of the viewport. With this commit, we add a setting to make possible to
scroll to a position x% pixels from the viewport. Besides of that, we
add a setting to make an animation of this scroll.
If nothing is changed on settings.json the Etherpad default behavior is
kept
Shut down database connection and exit the node process
when SIGTERM is encountered. This is especially important
when nodejs is run as PID1, e.g. in a docker container.
Shutting down connections to clients (browsers) is beyond
this patche's scope.
Resolves#3265
Users still cannot choose which shortcuts they want to enable/disable,
so it does not make sense (yet) to have a cookie with that preference.
This can be reverted once we create an UI to change shortcuts, but
PLEASE PLEASE PLEASE do not read the cookie every time handleKeyEvent is
called!!!
This is an adjustment to #2891.
On some erros that display a modal with "Force reconnect" button, allow
Etherpad to automatically reload pad after a few seconds. Amount of
seconds is defined on settings.json.
Still need to create tests for this feature, and implement i18n.
This meant plumbing a callback through to `compressCSS()`, which meant that
I had to alter the innards of `getFileCompressed()`. I tried to leave that
function looking more understandable than when I found it; for example, I
flattened out the nested `if`.
I went ahead and upgraded the version of `clean-css` while I was in the
territory.
The semantics of all the substitutions are identical to what they were before.
I _did_ take the liberty of formatting the CSS to be a bit more readable
(at the cost of adding a little bit of whitespace).
