 There are no users on the Users tab.  I do not have email enabled. The
 users folder in default (the only one under the ComSwiki directory) is
 empty.

how about this:
1) try creating a new user (as derrel mentions)--i think it will  
still create one even if it can't e-mail the user
2) then, go to the users folder--it shouldn't be empty. edit the  
file to find out the password assigned

if that doesn't work, you may need to enable e-mail.



 Also, create another Aniweb and try that. Make sure it inherits from
 Ani and not Refs.
 Did that. Same problem. No users.

 Also create a CoWeb using Refs and see if that works.
 I created a Swiki that inherited from Refs, but there are still no  
 users
 anywhere.


access to non-ani swikis are handled via the admin interface, security  
tab

create a  profile, then you can create username:password or addresses/ 
address ranges who have various levels of privilege.

this is a separate user space from the aniani user space

Re: [Pws] Sourceforge: Yes

2008-03-07 Thread Hal Eden
anyone aware of squeak-based projects hosted on sourceforge?

i know the vm and plugins have a presence there, but as david points  
out, it may not be suited to squeak development processes, but that  
may just be my ignorance.

actually, the swiki development process may not be all that well  
suited to the usual squeak development process, given the duality of  
the in-image aspect and the file-system ATA+ (addresses-templates- 
action-and-other-things) aspect that are part of the overall swiki  
development process.

i haven't thought these issues through, but we may want to hash them  
out a bit to come up with the best way of supporting the community.

Re: [Pws] FW: [Swiki-bugs] SWIKI 1.5 Cross-Site Scripting

2008-03-05 Thread Hal Eden

(hmm, the auto-reply didn't work on my last message)

the issue goes beyond this.

for this sort of behavior, you can at least turn off things like  
append unless the person signs in. sure, if you have an open swiki,  
then they can do what you describe.


for the behavior the bug reporter described, there is no way to stop  
the behavior. (for a novice swiki administrator). the key thing is  
that the remote culprit, by putting this in a link on their page, can  
make it look like the message came from YOUR swiki.


(although in this case it is pretty clear  that something is awry  
because the not found message can still be seen, one could probably  
throw up a div that covers that, or something)


the behavior happens because the not found template is putting the  
raw url back out and when the scriptalert(XXS)/script is seen by  
the browser, it executes the script.


we could sanitize the url before putting it back out there to avoid  
such circumstances.


are there future patches/releases planned?

It appears to be a vuln in the Swiki software itself, from what I

The particular one I am looking at is (at a client) is say X  
so if I goto http://host:8000/X/1 i'll have the option to create  
a new entry which posts to 1.append. By inserting javascript into  
the textbox displayed, the application stores the data without  
escaping the javascript. Because of this, every time I load the http://host:8000/X/1 
 the javascript is executed.

quick fix:

on the [shelf] level

created safeurl shelf action which took the url action and wrapped the

then replaced ?url? with ?safeurl? in the shelf notFound template.

probably needs more careful study, but that's a start.

you might try turning on debugging and logDebuggerStackToFile in the

Re: [Pws] problem starting Squeak

2006-06-27 Thread Hal Eden

hi, christopher,

i think that the problem is (given the message that you gave) that  
your DISPLAY environment variable is not set, indicating perhaps that  
you are trying to run this when logged in remotely via ssh/telnet OR  
that you are running from a raw console (without starting up  
Xwindows).


so, one option is to make sure that you do this within an X session  
(i won't go into a tutorial on Xwindows right now). the problem with  
this is it is difficult to to this from a script--if that is what you  
are trying to figure out.


another option is to run your swiki headless. take a look at http:// 
minnow.cc.gatech.edu/swiki/92. (i believe there is a way to connect  
directly into such an instance via VNC, although i haven't done it  
myself).


what i do is to run a vnc server, which establishes its own Xwindows  
environment and then i run the swiki within that. (i'm sure this was  
borrowed from somewhere on the web...)

-
#!/bin/bash

vncserver -kill :1  /dev/null 21
rm -rf /tmp/.X11-unix/X1
vncserver :1 -name Squeak -depth 15
(
  cd /where/my/swiki/is
  nohup ./squeak -display :1.0 -memory 50m squeak-dev.image 
)

hope this helps!

[Pws] bug in SwikiDirectorythumbnailOf:

2006-01-25 Thread Hal Eden
if JPEGReaderWriter2 fails (i just reported such a case to Mantis)  
while creating a thumbnail, the file has been created, but is zero  
length.


as it turns out this is not a problem at the time, because the sender  
of thumbnailOf: (at least in the case of the image-plugin) seems to  
handle things properly and puts the unthumbnailed image in the  
generated html.


however, another access to the page thinks the thumbnail has already  
been created because the file exists and a reference to that zero- 
length file is put into the generated html.


how about injecting this into the ifError logic at the end

ifError: [:a :b | self deleteFileNamed: thumbnailName. ^nil]

(and i'm not so sure the ^nil a couple of lines above that might not  
be problematic, as well--might be better to just error there and let  
the final ifError clean up)

[Pws] NuSwikiPage(class)safePageNameFor:

2006-01-24 Thread Hal Eden

i just ran into an issue with this in (finally) upgrading from 1.3.

while it is an excellent thing to do, it ended up breaking links to  
existing pages whose names were not safe (e.g., i had some pages  
that somehow had spaces at the end of the names. if someone edited a  
page that pointed to them, the links on the edited page became  
create button links).


an interesting point is that even changing the names and saving the  
page did not seem to help (haven't figured that out yet...) unless i  
restarted the server afterward.


it would seem that there are basically 3 places that bad page names  
can come into the system:


1) creating a page
2) renaming a page
3) loading old pages

adding a safePageNameFor: check in  
XmlSwikiStorageloadPagefromstartingAt, is one way to get at 3)

[Pws] enhancements to inline plugin

2006-01-20 Thread Hal Eden

hi,

i've been working for some time on ways to do things similar to ? 
inline?, but before plugins were really working, so i had added a *|  
pageref|* bracketing notation to my local version in order to do it.


now, my approach was very focused on some needs that i had in the  
context of creating reflection spaces that work alongside our face-to- 
face collaboration action space, so i'm not claiming a high level  
of generality here, but i thought i'd describe some pieces of that  
effort.


i found that in addition to being able to inline the entire page  
along with a header for that page (as the inlinePage template does),  
it is also useful to have it without the header or to have a summary  
of the info. (ideally the summary version would be automatically  
generated, but for now i've been using forms to allow the creator to  
specify a summary when they edit it.)


the other aspect i have been looking at is the use of ajax-like  
techniques (based on notes by avi bryant and others) to make the in- 
lining a dynamic process. in our environment, the simulation  
component can create information displays and dynamically update them  
on a swiki page. by having a watcher page that is dynamically in- 
lining the contents of the information display page allows the  
information generated by the simulation to be continually updated on  
a separate display screen.


based on my recent upgrade to 1.5, i have come up with a version of  
the inline-plugin that retains the original behavior, but will also  
permit the use of address suffixes:


?inline page=pagenum.summary ?

and adds a dynamic option

?inline page=pagenum dynamic=true ?

if you want to take a look at it, the prototype is at:

http://swiki.cs.colorado.edu/Reflection/16

although to get the dynamic effect, you really have to be here or  
happen to catch us in a demo/session.


my main reason for posting is to ask the question: have there been  
discussions around how ajax-like capabilities might be used in  
swikis? if not, is there any interest in generating such a discussion?


all the best,

hal

The URL doesn't work for me. I am interested in seeing it in action.

Peace and Luck!

[Pws] swiki browser broken in 1.5?

2006-01-18 Thread Hal Eden

hi,

finally getting around to trying out 1.5 and there seems to be a  
problem with the swiki browser.


when i try to save an edit on actions or addresses, it can't resolve  
the reference to, for example, book and asks if i want to create a  
temp or instance variable, which i'm pretty sure i don't want to do.


it looks like the bookContext method on the SwikiBrowser class is  
returning:


[:t1 :t2 :t3 :t4| t4]

shouldn't that be something like:

[:request :response :shelf :book | book]

?

2006-01-18 Thread Hal Eden
yeah, i thought it was probably that given you note about needing the  
sources to do any development--just wasn't sure if that included  
using SwikiBrowser.


i was upgrading from 1.3 and it was working there, so was wanting to  
make sure i hadn't done something wrong in the process.



thanks,
