Re: [eclipse-dev] consistent CVS tags for builds?

>  time := the current time in HHmm format

Is there any standard time zone to be considered?
Since we're specifying a convention, it's worth mentioning.

Since I'm on the west coast, I try to tag using Ottawa time because most of my teammates are there, and because the build time stamps use that time.
And if I use my local time, it can actually make my submission look older than a previous one....

Subject: [eclipse-dev] consistent CVS tags for builds?

The component teams seem to have different conventions for CVS tag names
when doing build submissions.  I believe that consistency is a good thing
unless there are good reasons for tag name creativity (are there any?). In
the past, we even had to re-spin builds because inconsistent tag names lead
to non-increasing bundle version numbers. (To be fair, this only happened
if one component in itself was inconsistent though.)

CVS tag names appear in bundle version numbers, in the bundle jar file name
or directory name, and in the revision history for one specific file. They
should increase lexicographically over time as long as the major, minor,
and service segment of the bundle version number does not change, i.e.
within one development stream.

I would like to be able to derive the id of the build in which it first
appeared when looking at a revision of a file in the history view, or when
looking at a particular bundle somewhere on disk.

Kim Horne has volunteered to update the releng tools if we could agree on
the following form for tags (sorry for being formal here):


 date := the current date in yyyyMMdd format
 time := the current time in HHmm format
 branch_opt := "" if org.eclipse.releng is from HEAD,
                             "_<branch>" otherwise.
 branch := a compressed form of the branch from which org.eclipse.releng
is checked out.

The "compressed form" could be the first letter of the branch name followed
by any numbers in the branch name. The reason for compressing the branch
name is that tag names appear in file names and directory names, and using
the full branch name would lead to overly long names that could cause
problems on certain file systems.

For example, a regular contribution for this week's integration build would
use a tag like "v20080414-1526", and a build submission for a maintenance
build would use a tag like "v20080901-1130_R34". Looking at the first
example tag, we can tell that it was made from HEAD for a regular
integration build some time after April 14, 2008.  The second tag looks
like it would go into a maintenance build for the 3.4 maintenance stream.

Questions? Comments?


P.S. I know that this has been discussed in the past. I don't have much
hope that we can get everyone to agree on this, but I would consider it an
improvement if *most* teams would use a consistent naming scheme.
