Re: [equinox-dev] Does the fwk load the config.ini

[Thomas Watson <tjwatson@xxxxxxxxxx>]

Yes, and we should continue to do so.  If I understand you correctly, you are suggesting we avoid re-reading the config.ini in the case where the launcher already did it.  I think that is a good thing and I always thought it was a bit of waste that we re-read a file that the launcher already loaded for us.

As a side note, lets hold of on incrementing version numbers of the launchers until we get past M5 since we need to update all the host version ranges of the launcher fragments when we do that (https://bugs.eclipse.org/bugs/show_bug.cgi?id=399037)

Sounds reasonable to do that check.  I always thought it was a bit silly to re-read the config.ini in the EclipseStarter if the launcher already did it!

I’ve decided to stop reading the user configuration when the base has changed to minimize the risk of having erroneous information in the config.ini (bundles that are no longer available, config entries no longer relevant) that could harm the startup process.
A similar logic has been implemented in the simpleconfigurator and will be merged in master by Sunday night. The code is currently available in a branch called prapicau/sharedInstall-part1.
 
The code that needs to be added to EclipseStarter is as simple as an if statement accessing a system property set by the launcher.

Out of curiosity, why do you need to prevent the reading of the user's configuration if the base has changed?  I guess you released some changes to the launcher to do this same kind of logic.  You just now need to apply that logic in EclipseStarter so it does not clobber the changes you did to the launcher?

Your recollection is correct. Today the launcher reads the user configuration and then merges the based configuration, whereas the EclipseStarter only reads the user configuration.
The reason I’m looking into this is because I need to change the EclipseStarter logic to bypass the reading of the config.ini when the base has changed (which I can do easily since the heavy lifting is done in the launcher) but I wanted to be sure that not loading any properties in the FrameworkProperties would not be an issue.

Now that you mention that I am not sure what is expected to happen with the shared configuration and the config.ini files.  I guess it should read the users configuration and then merge in the parent configuration, or is it the other way around?  If I recall correctly the launcher does do cascade reading of the shared configurations, but I am unsure if the user's configuration overrides the parents or not.

At any rate, for shared configurations I think we depend on the launcher to do the merging of the cascaded configurations.

Thanks for the pointer Tom. I’ve looked at the code and I’m a bit surprise to see that this code is not handling shared configuration. Is that expected or am I missing something obvious?

Thx

If the framework is launched with EclipseStarter (which the launcher uses) then yes it does [1].
