Checking the loaded gt4gemstone version inside a GemStone extent
This page shows how to check the version of gt4gemstone loaded inside the GemStone extent and compare it with the client version.
First if the image corresponds to a Glamorous Toolkit release, the image stores the release version.
releaseVersion := GtImage version versionString
If gt4gemstone is already installed in the remote extent, we can connect to it and get the version installed there. The snippet below is a GemStone snippet.This only works if gt4gemstone is installed remotely and the version there is compatible with the current version of Glamorous Toolkit.
Using a plain GCI connection
If gt4gemstone is not installed remotely we can make a plain GCI call to the remote extent, and check if gt4gemstone is installed.
First we setup a new session. The session should already be configured.
defaultSession := GtGemStoneSessionRegistry default defaultSession.
We then check if the gt4gemstone release is present remotely.
classSearchResult := defaultSession evaluateAndWait: 'Globals classesDo: [ :aUserProfile :aSymbolDictionary :aClass | aClass name = #GtGsRelease ifTrue: [ ^ true] ]. false.'
In case a gt4gemstone release is present we can get its version.
self assert: classSearchResult = true.
remoteVersionString := defaultSession evaluateAndWait: 'GtGsRelease versionString'
We can check if this version is the same as the local one.
remoteVersionString = GtImage version versionString
At the end we need to logout from the remote session.
