Re: [wtp-dev] Proposal to move to "3.2 Style Builds" using ".qualifier"

Thanks Arthur. Adopters do not need
to make any changes to their plugins or features, they should continue
to use 
"1.0" in their "requires"
statements (or, maybe 1.0.1, in some cases, depending on their needs),

but never that 4th field. 

So, I would have said "no effect"
but ... wouldn't you know ... there did just happen to be guy down the
hall that 
had a custom build/copy utility that
proved me wrong. Since these types of problems would have 
to be fixed anyway, I do not think this
will be prohibitive and adopters can fix their scripts now instead of later
.. if by chance 
they were mistakenly assuming there
always had to be 3 fields. 

The experience did, however, emphasize
we should broadly disseminate the information, 
so I posted following to our WTP newsgroup.


and created a bugzilla entry for comment/problems.

Bug 125257 Should move to ".qualifier"
version of plugins, even for WTP 1.0.1
https://bugs.eclipse.org/bugs/show_bug.cgi?id=125257

I will, however, make the change in
our WTP M-builds tonight, so we will have time to 
react (or "back out") if any
issues found.

Subject: NOTICE to adopters: WTP 1.0.1
will move to use 4th field "service" qualifier in plugin versions
Date: Wed, 25 Jan 2006 17:29:07 -0500
Organization: IBM

 
 
I wanted to be sure this notice got
wide attention, so am posting here, even though
this won't effect "end users"
-- only those who adopt WTP in their products or
add ons, and even then, only those that
might "rebuild" it or otherwise have custom
ant scripts, or similar.
 
You can see or respond to following
bugzilla entry,
Bug 125257 Should move to ".qualifier"
version of plugins, even for WTP 1.0.1
https://bugs.eclipse.org/bugs/show_bug.cgi?id=125257
 
but in brief, there's good reason to
use 4 qualifiers
in a plugin or features version
identifier, such as, 1.0.1.v20060214
where that last one is the CVS tag of
the version
that was used in that build. This is
the plan for eclipse
3.2 based components anyway, and in
our case, makes
sense to move to this scheme now, even
though WTP 1.0.1
will still be based on eclipse 3.1
 
Typically this would be completely transparent
to everyone
(except for long ugly file names in
some cases 
 
but we have heard of at least one case
of one large
international business machine company
that
had some copy/build script somewhere
that didn't like the four fields very
well.
 
Since any adopters that have similar
scripts would
have to fix them for 3.2 based scripts
or builds anyway,
we are hoping to beg your indulgence
and get things fixed now.
Please post concerns or problems to
bug 125257.
 
Any adoptees of WTP would continue to
"require/import" simply
version "1.0" in the runtime
version of their plugins, so no
changes are required there (there might
be some cases where you'd
want to use 3 fields in a "requires",
but ... I don't ever think
you'd need or want to ever use all 4
fields).
 
For anyone who hasn't kept up with the
3.2 planned versioning scheme, the
best reference for it is

Thanks,
