Duktape ECMA/Java-script support

So my evaluation of javascript support in NS3.9 (Ubuntu 18.04) has found.

 

The version of duktape used is 2.3.  Reference found in duktape.h.

 

According to the duktape site version 2.3 is ECMAscript 5.0-5.1 compliant.

 

According to ECMAscript 5.0 documentation the try-catch statement is supported.

 

My testing with NS 3.9 shows try-catch is not working.  So something is amiss!

 

As jquery requires try-catch it is prevented from working in NS.

 

The DOM module is also severely truncated.

 

There are nearly 1800 unimplemented bindings listed in UnimplementedJavascript.txt.

 

Many of these bindings are critical!

 

It is my conclusion that there would be very few javascript enabled sites that the current implantation of NS3.9
could or would actually render.

Also needing to be remembered, is that javascript can be interpreted
differently, between different web browsers, and, between different
versions of the same web browser.

It is one of the problems of client-side processing.

Just out of interest, whilst the names may appear confusingly similar,
java is completely different to javascript.

Maybe. JavaScript is working here in 3.9, (Dev CI#4562) under RISC OS
5.25, RComp version (24-Aug 18), except on the site you mention. In
particular, https://javatester.org/javascript.html conforms that
JavaScript version 2.2 is working.

Best wishes,

JavaScript won't enable. Version 3.9.

Downloaded and compiled latest build 3.8 which turned out to be 3.9 in the about.

I have ensured that Enable JavaScript is ticked in the netsurf preferences content tab.

But when I visit any java site including :

www.whatismybrowser.com/detect/is-javascript-enabled

All sites claim JavaScript is not enabled.

Have I missed something?

Probably, although it should most likely check for its existence first
and fall back to the one that is provided with NetSurf itself (which
will always be current at the time the relevant release of NetSurf is
made). Patches to set_default() in frontends/riscos/gui.c are most welcome.

> Is it a command line option, for example?

The relevant configuration option is called "ca_bundle" and its value is
expected to be a (host-platform native) path to a standard certificate
bundle file. This may be set manually by editing the configuration file.
There is a corresponding "ca_path" which may be used to provide a path
to a standard indexed certificate directory (which is probably
irrelevant for RISC OS, as such a thing would have to exist first).

Like all configuration options, it can be passed on the command line, thus:

--<option-name>=<option-value>

So, for ca_bundle (on an OS that uses Unix-style paths):

--ca_bundle=/path/to/file

However, the command line should be reserved for a user's own
configuration choices and not be used in shipped software.

CA certificates file

Hi guys,

The CA certs file as supplied with RISC OS is some months out of date.
Also, RISC OS HardDisc4 distributions come with the same file, but in
a different location and under a different name.

Can NetSurf be made to use the one that RISC OS provides? Is it a
command line option, for example?

I'm looking at writing a little app that gets an updated copy of the
CA certs file if and only if it has been updated. If I can make it
work, it could save lots of people the trouble of working with an
out of date file or having to work out how to get an updated copy
without risking unexpected/unwanted changes to !Boot.

I didn't look in detail after I saw "width:1270px;".
If it contains such fixed widths and if centred in a narrower window it
would extend too far left and right offscreen. Widening the NetSurf
window brings it into view. If the window is already as wide as your
monitor, reducing the page to 80% zoom would probably bring it on screen.

It cannot be a negative left-margin as negative values aren't allowed.

You can try and decipher their CSS here:

(The page in NetSurf is blank. Press f8 then use search and replace to

There's a width of 1270px in there which may be responsible but I didn't

It was pointed out recently that the SVGs of QR codes, created by the
QrCode app by calling out to https://api.qrserver.com, render completely
black. They contain a line <rect stype=...>; deleting this line causes
them to be rendered correctly by NetSurf.

The Unicode resource (!Unicode) has very little to do with the Unicode
font library used internally by NetSurf.

Please provide a NetSurf log file (which can be found by running the
OpenScrap obey file stored in the NetSurf application directory -- shift
double click on !NetSurf to open it) from a crashing start -- this
contains copious information which will allow the developers to
understand what is going on. In all likelihood you have a font installed
that causes it to get confused. I thought we'd found and fixed all of
the issues here over the last decade, but clearly not.

On checking I seem to have messed up restoring files - I had reverted
to r4316 from Jan 2018, not r4335 from May 2018. Also, I hadn't
reverted the !Unicode folder in Boot.Resources when I thought I had.

But doing those correctly and then rebooting doesn't solve the

Crash on loading NetSurf

Message from NetSurf: "The Unicode font library could not be
initialised. Please report this to the developers."

I don't believe this is a bug - it's the aftermath of a crash.

This ARMini (RO 5.22) had been out of use for a period due to a house
move. I had been using release 4335, which seemed stable. I
downloaded release 4528 as the then most recent. This ran but wasn't
displaying some pages correctly. I think the next day I had a crash
while downloading email with NetFetch. This caused disc problems.
After using DiscKnight and repairing Messenger I then tried loading
NetSurf. I got the above error message. I deleted r4528 and reverted
to r4335. The error message still occurs on attempting to load
NetSurf. I double checked the modules in System to make sure they
were the ones that came with r4335.

My best guess is that a Unicode file has been corrupted. How do I
check? Where do I find an up to date version of Unicode to install?

NetSurf works as expected if you type a mailto: into the URL bar so it
not working from an indirect script seems odd, doesn't it?

Curious, I have just thrown together a PHP script here using those same
forms and a method which works in Chrome using header() and it too fails
with NetSurf. I found other postings with similar problems and one
suggested using the Javascript alternative to header() which works in
Chrome, but guess what NetSurf makes of that!! It works if Javascript is
enabled!!! Inform the gentlemen of the press!!!!

Well, here it's just happened again: GMail session logged out (not by
me this time!), account name ("one account. All of Google") - 1 screen ,
password input - second screen, error message at
https://accounts.google.com/signin/rejected?hl=en-GB&rrk=47&rhlk=js

"Couldn't sign you in

"The browser that you're using doesn't support JavaScript, or has
JavaScript turned off."

I tried enabling Netsurf's JavaScript, in case it was just doing a
stupid-level check, but the page is absolutely stiff with JS:

if (AF_initDataInitializeCallback)
{AF_initDataInitializeCallback(AF_initDataKeys, AF_initDataChunkQueue,
AF_dataServiceRequests);}if (!AF_initDataCallback) {AF_initDataCallback
= function(chunk) {AF_initDataChunkQueue.push(chunk);} etc etc

I managed to restore access by copying across the Cookies file from the
other computer again, but that cookie will presumably eventually expire
too. :-(
