Description Jesse Glick 2009-08-28 16:23:39 UTC
Currently from unit tests file attributes on the SFS such as displayName are not honored. Since there is a different SFS
implementation when core.startup is loaded, need an API to share the FS.Status implementation and avoid code duplication.

Comment 2 Jesse Glick 2009-08-28 18:07:46 UTC
Please review.
Comment 3 Jaroslav Tulach 2009-08-28 21:04:03 UTC
Y01 Put the implementation into non-public package. openide.filesystems and core.startup can use it and then you will 
not need to introduce the new public method at all.
Comment 4 Jesse Glick 2009-08-28 21:13:40 UTC
Y01 - that is what I considered first but core.startup has a regular dep on openide.filesystems and cannot use
non-public packages. I definitely do not wish to introduce another impl dep when we should be cleaning the ones we
already have.
Comment 5 Jaroslav Tulach 2009-08-31 10:01:36 UTC
Imho, just change to

    private static final DEFAULT_STATUS = new SFSStatus();
    public Status getStatus() {
        return isDefault() ? DEFAULT_STATUS : STATUS_NONE; 

and in core.startup don't override the getStatus method. That seems like the least disruptive API change. It is 
compatible inside NetBeans based application. Slightly incompatible for external use, but nobody shall really suffer 
from such change.
Comment 6 Jesse Glick 2009-08-31 14:04:35 UTC
Good idea, I think that would work.
Comment 7 Jaroslav Tulach 2009-08-31 14:25:01 UTC
I am adding the API_REVIEW_FAST back, it is still a functional API change and I would recommend to document it in 
apichanges.xml. No need to wait with integration, imho.
Comment 8 Jesse Glick 2009-08-31 14:52:15 UTC
Some minor complications are caused by the fact that, due to jtulach's ADD_FS in 4701064c3bc5 and 43328c9c8232,

  new Repository(FileUtil.createMemoryFileSystem()).getDefaultFileSystem().isDefault() == false

contrary to what one might expect, and changing isDefault to say

  return repository != null && this == repository.getDefaultFileSystem();

does not work either (because repository == null). This code is so convoluted I do not dare touch it.

Integrated into 'main-golden', will be available in build *200909010201* on (upload may still be in progress)
