WAMagmaSharedSession
by Keith Hodges 09 Sep '06

09 Sep '06

In the latest Magma seaside package I have added an experimental session that only uses one session per repository. This makes sense (I think) for pier because pier manages its own model locking on its model. Performance is much better too Keith ___________________________________________________________ Try the all-new Yahoo! Mail.

Magma+Pier integration It works!
by Keith Hodges 09 Sep '06

09 Sep '06

The story so far.... you need Seaside latest (Scriptaculous latest optional) you need Pier you need Magma, MagmaServerLoader from squeaksource/Magma or squeaksource/MagmaTester you need 'Magma seaside' from squeaksource/MagmaTester you need Pier-Magma from the pier repository. you will also need Pier-Seaside-kph.80 or greater and Pier-Model-kph.79 or greater these are my changes to Pier that have yet to be ratified by Lukas. ---- With all of that loaded. 1. In pier configuration, add the WAMagmaConfiguration to the configuation panels. 2. override the magma repository setting, and 'Magma Control Panel' should appear. 3. Enter a directory name for your pier repository (it doesnt have to be a fully qualified pathname) e.g. 'magma-pier' click 'Save' to accept this setting 4. Click on 'Magma Control Panel', which will inform you that the repository does not exist. 4a. If you are on seasidehosting then you will have to manually create the repository directory. 5. Given the list of options as to what repository to create, click the 'create' button (and wait). 6. The existing pier kernel should appear in the list with a 'persist' button next to it, click 'persist'. 7. Try it and see! I am about to go and try my own instructions out, and then I shall upload a preloaded image to ftp.seasidehosting.st username: preloaded password: squeak let me know how you get on Keith ___________________________________________________________ Try the all-new Yahoo!

magma pier
by keith hodges 08 Sep '06

08 Sep '06

Just thought that I would run this by you see what you think. My repository root is PRMagmaRepository which contains a dictionary in its 'store' instance variable. This dictionary contains values of PRMagmaPesistency which references in instance var 'kernel' a PRKernel (the root of the current pier kernel data structure) and also a dictionary for historical data. [I dont use this history yet because there is a danger that it might indirectly reference the session] Whenever the kernel data structure is edited this is managed by a mutex, (an instance var of PRKernel). I have arranged that whenever this mutex is used (as in critical: [] ) my class PRMagmaPersistency is able to wrap the critical block in a magmaSession commit: []. doing: aCommand critical: aBlock aCommand context session commit: [ self kernel critical: aBlock ]. At this point I thought that this was all that I would have to do in order to get things working, because I thought that once the commit was complete all other users of repository objects would be automatically be updated. Was that a valid/sensible assumpton? Now I discovered that the structure that I am viewing in seaside is not necessarily the same one that is in the store. I thought that it would be, since I just put it into the repository. If it is not then that would explain why a commit: is having no effect because I am committing something that is not reachable from what Magma has as its root. My next plan was to ensure that when seaside attempts to access a PRKernel instance at the beginning of a session it does it via the PRMagmaRepository instance which can ensure that it gets the one out of the repository. getPersistedKernelFor: client | persisted | persisted := client session root store at: (self kernel name) ifAbsent: [ self inform: ('not found in database: ', self kernel name). self ]. ^persisted kernel I dont think that this approach is very fast, but it works. Is that to be expected? Now it appears that if I manually change the database via my own little session. The current seaside session does not pick up the change. If I restart the seaside session invoking the above code, then I get the new data ok. So thats what I am doing so far... any comments? Keith

Magma + Seaside integration
by Brent Pinkney 05 Sep '06

05 Sep '06

Hi, I see that Keith has released some Seaside + Magma integration monticellos. Since he and I are not (yet?) sychronising our efforts, I have posted my integration change set to http://minnow.cc.gatech.edu/squeak/5817. This version is compatible with Chris's latest release; the wiki page has all the instructions. Evaluate "WAStore workspace" if the workspace does not open. I am sticking with the change set approach as it highlights (to me anyway) how little needs to change to modify the Seaside demo to have a Magma repository. Comments are welcomed. Brent

Magma+seaside store shakedown
by keith hodges 05 Sep '06

05 Sep '06

Bug: 1 --------------------------- As you checkout you get: MagmaUserError: a WAOrder cannot be added to a MagmaCollection because it does not support all of the indexable attributes. > I did not manage to reproduce the error > MagmaUserError: a WAOrder cannot be added to a MagmaCollection because > it does not support all of the indexable attributes. I did checkout but did not enter a name (the rest of the field must contain someting because of the validation errors). "So the WAOrder cannot be added to ....." happens if it is passed empty fields. Bug: 2 ----------- search in store app needs updating to use the query interface rather than read: from: to: which is no longer supported. Bugish 3: ---------------- Store example uses MaAsciiStringIndex which we have been informed is deprecated Keith Send instant messages to your online friends http://uk.messenger.yahoo.com
