RE: Magma start

The startup would be so problematic unless you plan to use it lazily as I was hoping to be able to. A solution for the startup delay would be solved by using a big magma server who is allways running and lots of clients use it. The problem with that is scale. I don't think one Magma server will scale as much as I need (mostly due to Squeak memory scaling). But I'm pretty confident N magma servers will do the job.

It routinely took 20-25 seconds on a centino 1.8GHz in a compaq 6510b laptop to open a repository locally. Then, it would take another 20 seconds or so to add a root object, which I did a lot while I was trying to figure out what I didn't understand! So...no answers, but I can confirm your problem, I think! Other than that, I haven't figured anything out yet... Rob

r41Beta2
by Chris Muller 30 Mar '08

30 Mar '08

I just posted this new configuration is to the MagmaTester project of SqueakSource. It is a new beta for release 41 with two fixes from the beta1: - Fixed regression with #in:, #includesAnyOf: and #includesAllOf: operators for querying MagmaCollections. - Fixed scalability problem with the new refreshAll fix for single-user repositories, which is used when connecting sessions. Slow connection to multi-user repositories will be fixed next.

Magma start
by Sebastian Sastre 30 Mar '08

30 Mar '08

Hi there, I'm starting Magma in an image and see it has a delay of 15 seconds to start in in a centrino 1.8GHz. Is that time normal? I measured the console server and it spent near 11 seconds to complete #open: and near 5 seconds to complete #processOn: Is anything I can tune to reduce this times? thanks, Sebastian Sastre

Bug in in:
by Norberto Manzanos 26 Mar '08

Hi! I think the r41Beta has a little bug when performing a search using in: This method ^(self root at: #aCollection ) where:[:each | each aMessage in: keys ] answers a MagmaCollectionOptimizedReader where it must be a MagmaCollectionFilteredReader (I think). Anyway, the method worked fine in previous version. Thanks Norberto

lot of .hdx files
by Oleg Korsak 17 Mar '08

17 Mar '08

hello. result := (self recipients) where: [:each | each id > 0] distinct: false sortedBy: #lastName descending: false. this "where:distinct:sortedBy:descending:" creates some .hdx files everytime I'm calling it. 4067301lastName-keys.1.hdx for example. So after more calls I have a lot of these files. Is it ok? :S All of them are 100byte long. thanks

Updating an index
by Norberto Manzanos 15 Mar '08

15 Mar '08

Hi, Magma People The question is: is there a way to force an index to update its keys? or Suposing an index is not properly updated or is not updated at all, can I force this updating? You would demand: why do you need this? Perhaps something is wrong in your objects, so the index is not updated. No, the problem is that this index doen't match with an instance variable of the objects in the collection. It's a key generated when other condiciones changes, produced by a message, not an instance vairable. I suposse that magma doesn't update the indec because there's no changes in variables. Am I wright? But you would insist: why do you need this? A "calculated" index? Why don't you use a variable? I have this situation: there are several methods for testing the objects, that answer a boolean. I need to filter the collections regarding wich objects answer true, and wich others answer false. I need something like a filter, but I didn't find it. The way I found to solve this problem is to generate a single key that uses the boolens as they were bits, so with an integer index, I cant retrieve the objetos with several filterings. But the index is not updated! The only way is to remove and recreate it. Thanks in advance. Norberto

is it safe to quit Squeak with an open session
by Hilaire Fernandes 05 Mar '08

05 Mar '08

I am wondering, Is it safe -- in the long term -- to close Squeak without closing first the connexion to the server. Will it left open stuff in the remote Magma server? I am using a Magma client in a Squeak plugin, and the user can close the Squeak plugin at any time (closing the browser, move to another html page) Hilaire
