[VOTE] Release XmlSchema 2.0
https://repository.apache.org/content/repositories/orgapachews-001/
The above URL is a staging repository for the proposed 2.0 release of
XML schema.
This release is a significant housecleaning of XmlSchema: updated to
use Java 1.5 collections, rationalize the data model, and generally
try to make it a simpler and more efficient beast.
The CXF trunk has been testing against this version for a couple of
months now, so I think it's time for a release.
This vote will run for 72 hours.
Options as usual as -1, 0, +1.
I vote +1.

+1 - it's been "out" a while and pretty well tested now.
Thanks!

I personally think it should keep the existing package names. It's highly
unusual, I feel, to have version numbers burned into the package names. I
don't see many (any?) projects doing that.

[RESULT] [VOTE] Release XmlSchema 2.0
Posted by Benson Margulies <bi...@gmail.com>.
We have 4 +1 votes and no others.
And I apologize if I veered into grumpiness on the discussion about
compatibility.

Benson,
Those questions were food for thought, and I am in no way going to stand in the way of a release or the great work you are doing here.
I have just experienced the pain of two things with the same classes in the same classloader, so I was trying to ensure that a thoughtful decision was being made.
+1 to releasing something better now, even in the face of theoretical pain later.

That's certainly true, which is why I don't want to press the issue.
OTOH, it makes me wonder why the question didn't come earlier. It
should be a standard question whenever someone introduces binary
incompatibilities in a library project.
Just believe me, from the experience with various libraries from
Apache Commons: Sooner or later, you'll encounter someone with
different versions in the classpath.

Re: [VOTE] Release XmlSchema 2.0

It isn't very hard to migrate, which is one of the reasons why I
didn't start from a blank sheet of editor buffer. It took me an hour
for all of CXF's rather complex uses.
Such an app would be somewhat screwed. It would need to play with
classloaders to isolate the consumers of the two versions.
HOWEVER,
In the nicest way possible, I wish to point out that a release vote is
a very late moment to start posing these questions.
I further want to point out that the maintainers of the code consist
of me and some small contributions from others. I don't have the
bandwidth to design and implement some sort of complex migration
strategy.
Based on list traffic, I can estimate that there are perishing few
things in the world that incorporate XmlSchema. Do you think that very
many people try to cram CXF and Axis onto one webapp? I don't.
AFAICT, it's quite common to make incompatible changes at major
version boundaries, and, yes, this leads to some pain for some people
who do a lot of mixing and matching.

RE: [VOTE] Release XmlSchema 2.0
Posted by Tom Jordahl <tj...@adobe.com>.
A few questions for thought:
- Is the API transition from 1.x to 2.0 fairly easy?
- If a single web application depends on two pieces of "third party" software, one using 1.x and one using 2.0, will that web application be totally screwed?
- Is there a simple way to make migration and coexistence easier? Would changing the package name be that way?
Having faced many of these type of issues from the user side (since I work on stuff that basically integrates as or into Java web applications), anything we can do to make coexistence easier is a big +1. On the flip side, changing package names is pretty ugly.

No, it isn't compatible.
I can see your logic as to how someone might end up with incompatible
versions, but I don't, at this point, want to change the package
names. 2.0 has been under development for a year, and I've advertised
it on the user list, incompatibility and all, on several occasions. No
one has raised this issue.
Anyone who runs into this can always use classloader technology to
achieve isolation. I won't claim that this would be painless.
As an example of another ASF project, I think that commons-http client
has not changed package names as they have gone through several major
versions of incompatibility, though I could be confused.
Obviously, it would only take me about a day to change the package
name, so if there are a bunch of people who agree with you, I'll
capitulate. Let's see what other people think.

Is release 2.0 binary compatible with 1.x? If so, a clirr report would
be good to demonstrate this compatibility.
Otherwise, wouldn't it be better to change the package name? Note,
that schema is a component that is relatively likely to be used by
different parts of an application and in different versions.
