Hi,
what is the state of the persistency layer in Pier ? What is implemented
and what is not ?
Thank you

New subject: [Smallwiki] [Pier] State of persistency ?
Dear Damien,
I am also working on the persistency issue, I need something working
well as soon as possible. Content authors for my site are nagging me
already, we go live in October.
I figured that magma was at least worth a try. As as DB it is all in the
smalltalk image without any dependency upon external servers. Magma
appears to be aiming to make persistency as simple as possible. Raw
performance is unlikely to be an issue for me. It seems like the right fit.
I would have had something working by now if it were not for my windows
installation taking a dive due to disk errors. I am now up and running
again (just about). In the next couple of days/weeks I should have
something to show for my troubles.
If you want to try magma with seaside there are some updates/bug fixes
around (email me or, check recent history of the magma list because the
repository has yet to be updated)
best regards
Keith

In fact, my Pier setup is meant to be used for a static website with
very rare modification and by only one person. I don't think I need
magma at all, but thank you for the proposal.

My personal website has exactly the same requirements: mostly static,
rare modification, editing only by one person (me).
I just save the image after changes.

Staring at the code I want to override PRKernel>>critical:
PRKernel>>critical: aBlock
PRKernel persistency critical: aBlock
----
PRNullPersistency>>critical: aBlock
self kernel mutex critical: aBlock
----
so that when I subclass persistency I can nicely inform the database of
the changes
PRMagmaPersistency>>critical: aBlock
session commit: [ self kernel mutex critical: aBlock ]
-----
I know there is provision for over riding Persistency>>log: etc.
Is my plan ok or would it be considered bad style?
Keith

I am going for a rewrite of
PRCommand>>execute
self isView
ifTrue: [ self shouldNotImplement ].
self kernel persistency critical: [ "changed to go via
persistency"
self doValidate; doExecute.
self isLogged
ifTrue: [ self doPersistency ] ].
self doAnswer
PRPersistency>>critical: b
kernel critical: b
Lukas, is that a change that would make it into the main stream?

I see, this completely makes sense. Please commit.

Hi Keith
I would really be interested to learn more about it.
I thought that using a changeset-like mechanism for a domain that is
open (and can be extended)
is a problem and may break the restoring facilities.
I was thinking that we could at least save the page in XML or a
similar format after each command.
and we could recover the lastest changes.
Will you publish and share your code?
I would love to get a Smallwiki version whose image could get
corrupted and that I could reconstruct :)

Do you know Thomas Froeb's
PRXMLPersistency? You can get it at
http://source.impara.de. I use it for a project wiki and it works quite
fine. There are some problems when restoring an old version when a page
title contains a german umlaut like ä.
That Persistency module stores all data in XML-files, every version in a
seperate one.

Interesting. How does it version the changes in the tree, e.g.
deleting, moveing, copying, renaming pages?
