RE: [dsdp-tm-dev] RSE Extension Help

Hi Dave,
So the good news is that the Windows Shells > Server
Connection Settings property page (ServerConnectionSecurityPropertyPage.java)
persistence is now working for me. The bad news is _my_ subsystem
persistence is not. What's more, I've also found that the Windows
Shells > Shell Settings property page (SystemShellPropertyPage.java) is
not persistent. Looking at the code briefly, I see that the two Windows
property pages are implemented differently, with the latter implemented
more like mine.
A curiosity is
that ServerConnectionSecurityPropertyPage is derived from
ISystemConnectionWizardPropertyPage, thought in fact it doesn't appear in the
New Connection wizard.
Can you see if you can duplicate the problem with the Shell
Settings property page? Should I concentrate on mimicking the way that
ServerConnectionSecurityPropertyPage provides persistence?
Tom
Hi Tom, There have been a number of changes to the way
persistence works so I'd suggest updating from CVS and see if there's a
difference. I'm not sure if updating Eclipse would make any difference.
I haven't looked in detail at the windows shell subsystem thing yet - at
first glance it seemed to be working for me. Let me know how it goes with
the updated RSE. Thanks,

Hi Dave,
Unfortunately I had already fixed
setDirty() in my local sources and didn't see the problem go away. Can you
duplicate the problem using the Windows Shell Subsystem as I mentioned below?
FYI, I think I pulled my sources from CVS early May. Should I
update? If so, should I update Eclipse as well? I'm currently on
RC3. Tom

Hi Tom,
Thanks for mentioning the SubSystem.setDirty()
problem. That turns out to be a bug responsible for some other problems
too. It's fixed now (in CVS) and I'm hoping that should fix the problem
you hit too.

Hi
Dave,
Thanks for the tip.
I'm using your suggestion, but I'm having
troubles persisting my ISubSystem data. From applyValues(), I'm calling
SubSystem.setDirty(true) and then SubSystem.commit(), which in turn calls
RSEPersistenceManager.commit(ISubSystem). This last call looks to see if
the ISubSystem is dirty, but then it requests a commit of ISystemProfileManager
with no more mention of the ISubSystem.
I checked and I see that
the Windows Shells Subsystem seems to behave similarly. E.g. if I disable
'Alert me when connecting using SSL' in Server Connection Security and save it,
it is enabled again after I shutdown and restart Eclipse. Perhaps this is
a known issue?
Another anomaly that I thought I'd mention is that
SubSystem.setDirty(boolean f) ignores the boolean input and always sets the
_isDirty flag to false.
BTW, I figured out my earlier problem with the multiple
calls. It was a debugger quirk where a breakpoint set on an instruction
like this:
return
new TapSubsystem(host, getConnectorService(host),
createTapService(host));
will break twice for each single
invocation.

I think it depends on how you're persisting your
data. If you use RSE property sets to store data associated with a model
node (like subsystem) then the RSE persistence manager will be able to take care
of saving and loading the properties. In that case, I'd suggest making use
of properties outside of createSubSystemInternal() along these
lines:
- Make your wizard page implement the
following.ISubSystemPropertiesWizardPage.
You would implement the method applyValues(ISubSystem ss) which
will get called in SubSystemConfiguration.intializeSubSystem().
- In your applyValues method use property sets
to store your data associated with your subsystem
If you do this, then the property setting will only
happen when the subsystem is created via the wizard. After that (on
restart), RSE should take care of loading those properties associated with your
subsystem.

Sheesh, I guess
it was hard to pin down because the problem wasn't even occurring any more.
I'm guessing now that the troubles I was having were from not cleaning out
my profile between runs.
So, I guess I still have the other question about the
createSubSystemInternal() being called from two contexts, one when the new
connection is first created and two each time thereafter that the profile is
reloaded. Does it make sense to distinguish these two cases by checking
whether or not the IHost already has my data?

Hi
Dave,
The
stacks are identical. I see now that the two createSubSystem() calls have
a root higher in the call stack than I thought; I've attached a full call
stack below. It seems that finishPressed() is getting called twice.
I'm having a hard time pinning it down further than that, but I think for
now I've got something I can run with (unless of course you just happen to know
what is going wrong :-)
Thanks for your help.
Tom

Hi Tom,
I'm still not sure I understand this. The stack you show
here looks normal - on finish, the wizard should call createHost() and, in turn,
each subsystem configuration should have createSubSystem() called (which calls
createSubSystemInternal()). With my debugging I haven't hit a case where
createSubSystemInternal() is called twice for the same thing. Also, I
haven't seen a case where SystemNewConnectionWizard.performFinish() is called
twice. Could you show me both the stacks that lead to
SystemNewConnectionWizard.performFinish()?

Hi
Dave,
It's
not AbstractSystemNewConnectionWizardPage.performFinish() that's the problem.
It's SystemNewConnectionWizard.performFinish() that calls
createSubSystem().

Hi Tom,
I tried to recreate the scenario that you have but I wasn't able
to hit that problem. Does your implementation of
AbstractSystemNewConnectionWizardPage override performFinish()? If so,
does it end up calling createSubSystem()? I think the default impl just
returns true.

Hi
All,
I'm developing an RSE system type for JTAG debug
devices. For the properties of the debug device connection, I've appended
a custom wizard page which extends the RSE
AbstractSystemNewConnectionWizardPage. This wizard page is an adapter of
my SubsystemConfiguration object, which is itself an extension of the RSE
ServiceSubSystemConfiguration. When the wizard is finished, I'm trying to
add my extra properties to the IHost by overriding
ITapSubsystemConfiguration.createSubSystemInternal(IHost).
The problem is that when I click Finish, I receive
two calls to createSubSystemInternal(), one for the default wizard page and one
for my contributed page. It seems that the
SystemNewConnectionWizard.performFinish() is issued for both the main page and
for my custom page. This function calls createSubSystem(), which calls
createSubSystemInternal(), and thus the two calls.
I also noticed that createSubSystemInternal() is also
called at startup to load a persistent subsystem, which means that I need to
understand that the function will get called in two different
contexts.
For both cases I guess I could query the IHost to see
if it already contains my properties, but that smells fishy, so I wonder if this
is a problem with the RSE or with my usage.
Tom
