Then this must be caused by the subsequent merges of the different

Yes, this seems to be much more logical to me. It does not enforce
the prevayler model (snapshot/changes) to the persistency, but let it
basically do anything it likes: before a command is executed, between
the validation and the execution, after the execution, etc.

Why don't you give your persistency strategy a unique id then? Pier
(currently) does not enforce unique names for kernels.

That's cool, I completely agree.

Yep, that sounds nice to me.

I had a look at your changes. I cannot merge them directly, since
they break several parts of Pier and all my productively running images.
I just committed a manually merged version of your code, below you
find the comments:
Pier-Model-kph.107:
- PRPathLookup class>>star:path: you removed that, but it is needed
all trough the system
- PRCommand: I moved the mutex from the kernel into the persistency,
it seems to belong there so that we don't violate demeter. Now instad
of having the critical section within the command, the command passes
itself to the persistency by sending #execute:. The persistency
strategy then can call #doValidate and #doExecute at the right point
in time. I think this is more elegant and should even work better
with object database, xml, ...
- PRFilePersistency: I removed that class for now, it does not work
- PRPersistency >>#log: this is not needed anymore
- I don't understand the code to rename a kernel (why should that
matter?) and the code related related to #realize. I think most
people don't want to start right from a database, the use of a
persistency strategy other than the default PRNullPersistency should
be only possible after everything is setup.
- PRPersistency has no #snaphost method anymore, there was no need
for that anymore.
Pier-Seaside-kph.109:
- PRPierMain>>#structureAtPath: this breaks a possible setup with
Apache, I restored my old code but wrapped #start: into the root
context, so that it basically has the same effect as your modification.
- PRPierControlPanel: I would suggest that you add this class into a
separate package and/or transform it to a normal WAComponent so it
can be directly used from within Pier. I usually remove the config
application from productive servers. Moreover it introduces
dependencies to external packages that might not be loaded (Pier Unix
Security) and duplicates functionality that I already ported to that
package earlier on.
Hope these changes help to finally merge all the code again?
Thanks for your contribution!
Cheers,
Lukas

Smallwiki: placing box under dynamic menu on left
by Brad Fuller
With the left menu in a Smallwlki being dynamic (can grow up or down
depending on user's selection) how can one place a box underneath the
menu so that it moves dynamically with the growth of the menu? Is there
a way to do that w/o hacking the image?

Pier tools & Query engine
by Sébastien Julliand
Hi there!
I'd like to ask Pier users what kind of tools could be useful in order to
easily maintain their wiki (something like some reporting tools, specific
search queries and so on...). We (me and a colleague) will
work on this subject and try to make Pier's administrators life easier
;), with the help of Stef Ducasse. We have already some ideas but any
other useful ideas are welcome.
In the end, we would like to define an advanced query component for Pier.
By the way, Lukas, you said that you have already
done some work on a previous query component but you lacked the time
to finish it. Can you send us what you have done or at least give us
some hints? Thanks in advance.
Cheers (and happy new year!),
Sébastien

Fwd: [Seaside] Magritte for VisualWorks

I've released a reasonably functional port of Magritte into the Cincom
public StORE. Load MagritteForVisualWorks - it will prompt you to
load any further required parcels. There's some chaff left from stuff
that isn't supported in VisualWorks, but nothing that will impede
functionality.
