100 edits of a html file (adding and remiving a space) => +150MB of RSS that won't go away even if I close the file. 100 more edits => +150 more megabytes...

Sometimes it grows faster.

Preview is not even visible.

100 edits of a *.py or *.rs file => no leak.

Sample of a file where the leak is very pronounced:

<html>
<head>
    <script>
    var AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA = null;
    var AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA = null;
    ... (a lot of those)
    var AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA = null;
    </script>
</head>
<body>
</body>
</html>

Ouch. I've seen some memory leaks, but haven't been able to pinpoint it. Your leaky HTML file is very helpful -- I'll see what I can find. What version of Qt are you using? What OS?

@vi, could you please delete cParser...so, so Qutepart would not use C acceleration to highlight the code? Check if bug is reproducible without it.

Debian Stretch, amd64.

libqt5gui5:
  Installed: 5.7.1+dfsg-3+b1

No cParser.so => no leak.

Wow. @andreikop, thanks for asking the question and @vi, for the quick answer. I was planning on spending a lot of time looking at bizarre Qt / JS stuff.

What is status of this issue? (and Enki project in general)

Is it going to be fixed?

Hi
I'm not sure this issue will be fixed.
Enki is not among my priorities now, and there are no other active developers

Maybe then officially write on the site, on README and repo description that the project is abandoned?
