I must admit I didn't read anything before I did... ;-) Here are a few remarks: Download and installation on OS X El Capitan went smoothly, just the usual security warning ion first opening. Since I know Pharo is no malware ( ;-) ), this was not an issue There are several entries for Seaside, most of them warn me they are not tested/blessed for Pharo 5. They do not have a "Pharo 5" tag. So they could possibly be ommitted in this default view? The "Seaside 3" entry seems to be the suitable one, but fails with "This package depends on the following classes: ContextPart" it is not really obvious what the difference between "install stable version" and "install stable version and create group" is. The word group is something without any meaning in the context of Smalltalk to me... I clicked on the top-most entry just because I thought it's first in the menu for a reason. So I didn't really get far in this Sunday-morning-experiment :-( Joachim -- ----------------------------------------------------------------------- Objektfabrik Joachim Tuchel mailto:jtuchel@objektfabrik.de Fliederweg 1 http://www.objektfabrik.de D-71640 Ludwigsburg http://joachimtuchel.wordpress.com Telefon: +49 7141 56 10 86 0 Fax: +49 7141 56 10 86 1

Hi, What is it exactly? A pool of pre-open connections to a database, to save the connection time and make an application more responsive when doing data operations? Thanks for the update.

My understanding is that sqlite relies on file locking for write access, so as long as the file system is locking the file correctly, the db lock will work. HTH, Alistair

Hi hilaire I do not know if this is the anwser. Now I wanted to let you know that Olivier developed a session pool for database connexion.

I guess as long as the images are executed by a VM linked to the same SQLite library, the SQLite lock mechanism will work. I will test that.

Hi, i am testing with seamless on pharo 5 and all works really good. the only problem i see if i try to save the state of the image. if there is a connection active the vm freeze and stop to work. the only think i can do is quit and reopen it losing all changes. -- View this message in context: http://forum.world.st/Seamless-tp4840907p4901703.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] [Tiny ANN]: SlowEntryCompletion

by Sean P. DeNigris

Stephan Eggermont wrote > Is that something to add to the spec selectentity widget? Possibly. I'm still playing with it, though. In Magritte, there is no hook to change the EntryCompletion class, so instead I created a DynamicOptions class. That got me thinking that maybe an object could be passed to EC without subclassing... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Tiny-ANN-SlowEntryCompletion-tp4901519p4901671.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
