Hi Sandro,
I'm trying smallwiki on my laptop on windows xp
home and squeak3.6 but
I think there is a problem when I close and exit the image. To be more
precise, when I reload the image and restart the server, the pages in
the wiki are not updated with the last version. The problem doesn't
arise if I save the image before exit.
the available persistence of SmallWiki 1 bases on dumping-out the whole
wiki-tree regularly. All the wiki-data resides in the memory of the
image and therefor it is also persistent if you save your image :)
I set the storage in xml mode with "server
storage: SWSIXXStorage
new." and I force a snapshot with "server storage snapshot." but if I
close the image without saving, when I reload the image (and the
server), the wiki lose the pages that have been created after the
image has been saved.
I'm not maintaining SmallWiki 1 for Squeak and therefor I don't know
about the details of the port, the official implementation is in
VisualWorks. You should send further questions to the SmallWiki
mailing-list to get answers specific to the Squeak version.
I have always discouraged to use of SIXXStorage for the wiki, because
xml does scale badly as the wiki grows and we also observed strange
problems when reading in and parsing huge xml-files. Note that
SIXXStorage doesn't load the xml automatically upon opening the image,
you have to do this manually.
A file-based persistence has been implemented by Ralph Johnson in
VisualWorks.
I suggest that you use the image-storage in Squeak or wait for
SmallWiki 2 that will have a much nicer persistence system with GOODS,
an open-source oodb available in Squeak. Another possibility would be
that you implement a GoodsStorage by yourself. This should be fairly
simple and completely transparent to the rest of the wiki.
Cheers,
Lukas
