setTimeout() is subject to delays, possible massive ones. As such it
is rather useless for performance sensitive code. Use the non-standard
setImmediate() API instead, emulating it on postMessage() when it
isn't available.
The hacks needed to run these tests require proper handling of
properties. Unfortunately IE and old versions of Chrome mess up,
so just skip the tests there.
We have to temporarily replace window.navigator due to the fact that
its property languages is read-only. The tests for the translation
utilities require different values of this property. The failing tests
were added in merge of PR #718 (in commit
f5bf2d84ef).
Keeping it set for the disconnecting state was causing an issue where
the controlbar could be hidden without any way to open it, when a
session disconnects too quickly.
Supports server configurations that might prefer wss:// connections
on the default port, then proxies them through the web server to the
VNC server.
This proxy configuration is helpful on servers using self-signed
certificates. Accessing the https://host/vnc_auto.html page and
adding an exception for that host is sufficient to also satisfy the
wss://host/ request, unlike requests to wss://host:port/ which
may require an extra certificate exception.
RFB's _fail function logs the error, disconnects the session and sets
disconnect_reason. The disconnect_reason is upon disconnection sent to
the user interface. It is thus not suitable for including error details
that aren't user friendly. The idea is that you will look in the
browser console for a full log with details of the error.
RFB._fail() can be called at any time in any state, it is not certain
that we will get a close event on the socket since the socket might not
be open. This caused us to hit the disconnect timeout in such cases.
Fixes issue #678
For example, previously if the user typed in illegal characters in the
port field, no error would be displayed in the interface and the page
would stop at "connecting".
Node.js doesn't handle characters high up in the unicode range
properly with charCodeAt(). Adding a new test for UCS-4 codepoints
using codePointAt() to cover this.
