Bug #: 38163
Summary: Fix jquery.byteLimit issues with incorrect
blocking/limiting of input
Product: MediaWiki
Version: 1.18
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: JavaScript
AssignedTo: [email protected]

Classification: Unclassified
Mobile Platform: ---
Right now it tries to predict what the complete input value will be after the
keypress, and either allow or prevent that event.
However this is very unrealiable. For example if the limit is reached and you
select all and begin typing, you can't because it will do (this.value +
tobeinsertedkey) as prediction, and that's too long.
The solution is to watch *after* the key is pressed and then correct it.
Because we can't simulate all possible ways of insertion:
* copy/pasting
* drag/drop
* select>type
* autocomplete
* javascript-powered input methods
Initial attempt: I9ace3ab79 | https://gerrit.wikimedia.org/r/12713.
Reverted in: I1fe6a6c6 | https://gerrit.wikimedia.org/r/14175
because it caused the browser to limit the input field to 0 due to a browser
bug (could be the kind of bug that is actually documented in the
specification). So we'll have to do this another way.
