World: r3wp

No. How do I do that?

Louis: The plug-in extracts to the "Downloaded Program Files" directory 
in Windows. This is usually at C:\WINDOWS\Downloaded Program Files. 
To uninstall the plug-in, go to that directory, right-click on "REBOL/Plugin 
Object" and click "Remove".

OK, it works now!  Thanks, Josh.

Lots of things are starting to come together for rebol. I am glad 
for that. I have never regretted switching to rebol.

REBOL I believe has a great future.

All rebol lacks for me right now is unicode support, which I need 
badly.

Dunno if my last post last night made it.  as soon as I sent it, 
the world went down and i was unable to reconnect.  I think there 
is a misunderstanding about what a windowed control is, and that 
is throwing people off.  In the post I mentioned how MSAgent works, 
where you have a central server app that communicates with all the 
instances of the control, and I think something like that would be 
perfect for REBOL.  If there was a way to create an instance dynamically 
( using new ActiveXObject, for instance), then for those plugin scripts 
not needing the View UI, that would be a nice option, because that 
would allow using it from a WSF, as well.  On a side note, when trying 
to use the plugin in an HTA it's crash city.

ScottT, thanks. need do a lot of thinking here.

no problem.  I'm no good at REBOL, but I probably know IE a little 
TOO well.  I was able to create the OBJECT tag dynamically with no 
ill effects, though.  One thing I couldn't get working is transparency, 
though.  Don't strain yourself.  I'm sure it's a mess to get anything 
working.  I'll be in and out but reading religiously.

Got the Plugin working with Firefox ... thanks for the help ... will 
try and code a couple of demos tommorow.

anybody get it running in opera?

I tried setting the plugin up on opera, but it crashed, and now i 
can't seem to get it to load any more. does anyone have any idea 
how to tell opera to try to load the plugin again? (it is listed 
as registered in about:plugins)

Volker, re proxy-parsing: if you can post any REBOL code to read 
the proxy settings via javascript (via do-browser), that might work.

not too familar with proxy settings except through the auto-config 
script, which is just a javascript   here's a link: http://www.microsoft.com/technet/prodtechnol/ie/reskit/6/part6/c26ie6rk.mspx?mfr=true
 


But just because it's javascript doesn't happen to mean it's available 
through do-browser, I don't believe.

Yes, i mean that cauto-onfig-script. IIRC  it was not accessible. 
But digged not very deep.

you can't have multiple the same dll files in memory?

I still don't understand, how browser, loading it's rebol dll, has 
anything in common with being or not being thread savy ... you can't 
call the same dll from different thread of parent app?

Pekr, I can't go into details here. Sorry. Just know that currently 
it really is a thread problem.

JoshM - doesn't my private post re how Internet proxy settings in 
control panel influence registry help? IIRC, you set proxy in the 
past according to incorrect registry path. Please revise get-net-info 
:-) I prefer 90% working proxy, than none at all :-)

Pekr, thanks. I'm not in charge of get-net-info....not sure who owns 
that area actually.

That is REBOL code, and I pretty much only handle the C code. Sorry 
:(....maybe you want to ask Carl or whoever is leading the REBOL 
product development in that area?

petr: basically, C code has to be written specifically to be thread 
safe. rebol 2 is not thread safe, so the rebol dll is not thread 
safe either. this means that you can't use the rebol dll from two 
different threads in the same process. you could use the rebol dll 
from two different processes.

i'm quite sure rebol 3 will be thread safe so it will solve the plugin 
problem too.

Gabriele - who is in charge of get-net-info? That function is outdated 
and plain wrong imo, not serving its purpose well ... could we somehow 
cooperate to redesign it?

of course, if my assumption that plug-in uses it, is right :-)

i don't have gets

i don't have get-net-info here

so it's not in the source for the view installer, and not in the 
normal mezz code. has to be a different component.

help get-

so... as of now Carl is in charge of that code.

yes, i see it in view, but i don't see it in the source files :)

source get-net-info .... it uses registry functions, which, imo, 
are unset after rebol boots ....

i mean - i cannot fix it if i don't have the master source file. 
we can send improvements to carl, but i don't think he has time to 
consider them right now.

i'd say, wait after rebol 3 is out. that code will most likely need 
to be rewritten anyway.

but that is exactly proper proxy detection fails ... the code checks 
for proxy settings on inproper assumptions ... so - then why to release 
rebol 2 plug-in at all? :-)

I will study it once again to see ... but someone could confirm, 
if I am right thinking it is the function responsible for proxy detection 
:-)

Threads: Rebol puts important stuff in globals. That is similar to 
putting things in the globl context: with a single thread it is ok 
to change a var. With multiple threads andno coordination, itleads 
to chaos.. Think two threads use the  same interpreter-pc.

ok, ok, I just do not understand, why browser should use several 
different threads? Couldn't it be simply that they multiplex between 
various stuff? In such case  - nothing would be conflicting? (beware 
- just a speculation of non-experienced low-level "coder" :-)

don't tell me, that for each instance of Flash e.g., it uses separate 
threads? And what embedded OSes, which do not have threads? I wonder 
if it limits number of flash banners on the site displayed?

Thats the part called thread-safe. Such things can be done, but need 
some organisation. For example (speculation): rebol does something 
like
  forever[ do-next-step ]

And now that has to be changed insomething which returns in between. 
And save all theglobals currently scattered everywhere in the sourcecode.

But i guess each instance of flash uses really an own thread.

Some things are simpler then. As long as the threads dont need to 
work together.

Regarding multiple threads/instances: we're looking into a solution 
that may solve this problem.

Hi all. Hope you had a good weekend.

I am working on a design doc for making the default security settings 
for the plugin more restrictive.

I know we talked about it a while ago, but those discussions are 
long gone from REBOL and from the web......I apologize, I should 
have archived them. Can you repost your thoughts on the default security 
model, in *concise* posts please? thank you!

I'm sorry, those discussions are long gone from AltME and the web 
archive, that's what I meant to say.

BTW, you talked about rebol as external process,sharing window. Its 
not plugin, but could that work between rebol-apps? view-desktop 
could profit a lot.

hmm. good thoughts. I don't think that will go into the next release 
of plugin, but you could suggest it in the general REBOL 3.0 area

Extra Security, some thoughts:
- 'secure for ips, eg: secure [net ask tcp://rebol.com allow]
- don't share sandbox-folders between hosts.
- if possible memory-restriction, hd, cpu?
- clipboard-restriction somehow?

- check for memory-access, specially disable struct! . IMO real hackers 
will figure out how to inject code by poke. 

- reblets can store executable code by naming the file *.exe. Does 
not run immediate, but script can open folder in explorer by browse, 
and one wrong click runs it. (or is windows smarter now? Maybe you 
could add an own extension always, and maybe store everything as 
64#{} ?

- Make sure untrusted reblets don't run invisible, can snoop clipboard, 
or at least users online-times. I guess creatives can find other 
uses.

- Maybe some kind of log about starts/stops, with urls? To have a 
little chance of tracking. Some kind of global console.
- Running out of thoughts for now.
