Re: [orbit-dev] Versioning in Callisto?

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

That version is created automatically
by CVS when you create a branch.  In this case the branch is called
V2_3 so that is the default name of the root version.  See
        http://wiki.eclipse.org/index.php/Orbit
for more information on how things are
setup currently.

Subject	[orbit-dev] Versioning in Callisto?

I notice some of the existing projects in orbit are versioned with "Root_V2_3"
(for example). 

I suggest we use the convention of vYYYYMMDDZZZZ 

For a couple of reasons. 
If/when these CVS tags end up in bundle version number qualifiers, underscores
are problematic. 
(Impossible in a 3.1 base Eclipse ... which some people still use!  :)
 but I happen to also know some 
build and ant tasks use little heuristics, like "find last underscore",
or similar, so, no need to break 
them if there's no hard need). 

I'm suggesting ZZZZ to signify UTC time ... we are "world wide"
:) and while its extremely unlikely 
these will be versioned frequently, its a good convention in general, when
there's committers working 
in different time zones, since the relative value is critical, and must
always be monotonic. 

If anyone wants the original version in there too, that's fine, but I suggest
always at the end with a hyphen ... 
vYYYYMMDDZZZZ-230 (for example). 

And, just in case anyone was thinking we could only refer to the branch
name in 
map files or build scripts ... we always need to use _versions_ to be guaranteed
reproducible. _______________________________________________
