Making D0 L3 Release Process More
December 5, 2000
David J. Ritchie
This is an early description of the
project taken from a mail message sent to me.
This has not been reviewed by anyone but me so all errors and
inaccuracies should be attributed to me and brought to my attention.
Note that this has been evolving. The later documents should be consulted for
the current understanding. There are
elements within this document, however, which provide useful context.
David will start on this project January 2nd.
He will coordinate the D0 work through Amber and report within ODS to Margaret
and Ruth. He will work with Alan and Paul on the build scripts. It is not a
goal to have new process in place before March 1.
The goal will be to make the D0 NT code
building and release mechanism more robust and efficient for the Level 3
It is a goal to replace cygwin/srt scripts
with use of the CTBUILD dependency and build text files such that the builds
are done immediately in the Windows IDE environment. This should be done
incrementally if possible without requiring major changes from the developers
as the run approaches.
It is a goal to work with PAT to allow the
D0 Level 3 NT code to move to the latest version of ZOOM, which requires the
use of SiUnits. This may require some
time from Walter Brown. It is expected that this can be arranged with PAT.
It is an open question whether the work
should be targeted for Windows 2000 only. We are interested in the strategy of
the D0 L3 project on this issue.
Scenario’s for Need
Taking off from the above, I spoke with Alan and Paul and
developed the following three release scenarios:
- Three AM – Filter Change – Done by Shifter
with Expert on Phone
to be minutes to no more than an hour
as to what one is allowed to change
– Done by Release Manager
unlimited as to what one is allowed to change
Fixes – Few Package Change – Done by Level 3
not take more than a day
is a few package changes and the incorporating officially what was done
at 3 am
of Test Release Command Line Mode versus IDE-based approach
of Web Page to Generate Releases via One Button
Notes as the result of the meeting:
of the above take off from the “Production” (P) releases as they are part
of the Online.
will send around a description of the tasks.
