-------------------------------------------------------

Assuming the cache could be updated transactionally, couldn't Netbeans use the 
previous cache snapshot until the new one is committed?

Or are you saying that for new projects (where there is no previous cache 
state) this is as good as a blocking process? If you're saying the latter then 
I don't think we can do better. Intellij behaves the same way. At the very 
least the user is free to open other projects, close existing ones, browse 
files, while the process completes.

>             Project: NetBeans
>          Issue Type: Bug
>          Components: ide - Performance, java - Platform, platform - Execution
>    Affects Versions: 8.2, Next
>         Environment: NetBeans 8.2, Windows 10 x64
>            Reporter: Christian Lenz
>            Priority: Critical
>
> Often, while cloning, switching branch, merging, opening etc. etc. NetBeans 
> starts Background scanning for changes, but it is not real background, 
> because everything what you want to do then, like changing the branch, 
> commit, push, pull, open project, delete or whatever, is blocking by this 
> task and you can't cancel it, because it is essential.
> Either we need to rethink about this process like to make everything or most 
> of the stuff doing things in parallel or the task should really be 
> cancelable. It is a pain in the ass for big projects when they start to scan 
> for changes. 
> It is a real world case because you acan see it when you work on NetBeans 
> modules.
> Cheers
