Re: [wtp-dev] Notice of upcoming change in provisional api
Thanks Konstantin, these sound like
important changes, and sounds like you've used care not to break any adopters,
but I'll throw in a few complicating process questions.
You say "Ample
notice" has been given ... and,
I assumed you checked the scan data to confirm not used? But ... remember,
ample to us is not necessarily ample to others ...
Also, I am in the middle of proposing
some new processes governing how we change code, how we allow proper review,
etc. I haven't "published" it yet, since I asked the PMC for
a sanity check
and make sure I wasn't way off base
... but will hint here at some of the things I'm suggesting ....
I'm not sure they even apply to your cases ... but, without some review
process, no one may ever know ... so, some review
process would be nice.
One suggestion I am going to make is
that "new" work or "big changes" take place in a temporary
branch, so potential reviewers could "get at it" easier for review.
And, a component team level decision made as to when ready to go into head.
Another suggestion I'll be making is
that we "stage" our changes, to API or provisional APIs, so that
"we change them once", and that's it. I've heard complaints from
adopters that they'd have to change a little one milestone, then change
a little the next milestone, then some the next milestone ... sometimes
that's unavoidable, but our plan should be to "do it once"...
so, it'd be good to release code early in a milestone, once we knew if
we were at a point of "that's it", no more changes planned. Are
you at that point? Or do you have more changes planned?
I won't ask what your plans for API
are, yet, because then you'd ask me about Java 5 :) .... which, btw, I'm
almost ready to have that discussion too!
So, if you wouldn't mind waiting a bit,
then maybe you could be our first user of the new processes ... and then
you could help improve the process for the next guy?
[But, if its urgent for you to get these
in ... doesn't sound like you'd break adopters and you'd fix some important
bugs, so, don't let me slow you down .... too much :) ]

|[wtp-dev] Notice of upcoming change
in provisional api|
This is a notice that a change will be released
soon that has potential to cause breakage to users of the faceted project
framework’s provisional api. The change will be made to the HEAD code
stream affecting only the 2.0 release code line, so there will be plenty
of time for the downstream code to react if it is affected by this change.
The change has two parts to it:
1. The api and extension points that have
been deprecated during the 1.5.0 release have been removed. Information
about exactly which api has been deprecated and now removed can be found
in the following section of the WTP docs: Web Standard Tools Developer
Guide -> Programmer’s Guide -> Faceted Project Framework -> New
for 1.5. Ample notice has been made given in the past regarding this.
2. In order to fix a performance issue described
some api changes were necessary in order to remove the assumption embedded
in the api that facet version comparison is always done directly on version
string. The api change allowed the comparison information to be cached
thereby improving performance. The caching also allowed some api improvement
to take place because several methods no longer needed to throw exceptions.
I do not anticipate this change to cause problems for adopters as the affected
api is only infrequently used outside the framework itself. The api usage
scan did not produce any hits.
Both IProjectFacetVersion and IRuntimeComponentVersion
now extend Comparable.
The following methods no longer throw exceptions:
IRuntime runtime )
boolean ascending )
The IVersionExpr.evaluate( String ) method
has been replaced with IVersionExpr.check( Comparable ) method.
