Web Tool Kit CGI relay segfaults on linux ?

Hello everybody,

We have a WTK application running behind the Apache server on the Red
Hat Linux.

And we see a lots of the segfaults with the same parameters.
The application seem to perform OK and we do not see any VisualWorks
exceptions...

Does anybody have any idea where are they coming from?

The logs look like:

Dear Richard,

>I'm just getting back into Smalltalk (since 7.6) and see that I'm no longer able to pull up a namespace browser that shows the hierarchical namespace structure AND the classes in a selected namespace, which seems like a pretty useful thing to do.  I used to be able to do this by opening Tools.FullNotebookSystemBrowser from the "Old Browsers" package but no more after 7.6.  Bad news.

AFAIK, no, you're not missing something:  the UI you were using is no
longer there.  I created the NameSpace tab in the RB but at the moment
this shows the hierarchical namespace structure and the shared variables
that are defined in those namespaces, but not the classes.

>Or, if not, is there a plan to provide that capability at some point?
>
AFAIK, no.    Tweaking the RB tab to do what you want has been on my
would-like-to-do list for years behind more urgent stuff.

>Or failing all that, can someone outline how the old Tools.FullNotebookSystemBrowser could be updated and provided as a third party offering, if that's even possible.

I'd recommend working on the RB's NameSpace tab.  When that tab is
selected, and a namespace is selected in the left-most pane, the next
pane shows the namespace's defining package (in bold) and any others in
which it defines shared variables, the next shows the 'Shared Variable'
tab, and under it the protocols, and the last shows the shared variables.

1) Putting a 'Class' tab next to the 'Shared Variable' tab is how I
planned to proceed in the 4-pane browser.  The key issue is how to
reverse the usual left->right selection-update flow sufficiently that
selecting the 'Class' tab over the 3rd pane would change the packages
shown in the second pane to    be those packages in which the namespace
defines classes (its defining package appearing in bold in both lists).

2) As well, and possibly easier to start with, make selecting a
namespace no longer grey-out the 'spawn' and/or 'spawn hierarchy'
menupicks.  Let spawning produce a 3-pane (or 2-pane) browser that would
show the classes.  Some subclass or sibling class of an existing 3-pane
(or 2-pane) browser could be made to show what you want.

>Or are we SOL (simply out of luck) on this?
>

Hopefully, the above may help anyone who has the time I at this moment
lack to try and produce something.

> Any G2 appreciated.

Any goodie appreciated.

             HTH
