Core issues and status: (Toby) See
Toby's
run-down of issues of interest
here
and follow-ups below.
- Bug tracking: Richard recently initiated a discussion on
requirements for a bug tracker. On Monday Tony Johnson of SLAC gave
several of us a demonstration of
JIRA, (if link doesn't
work, try again in a day or two: web site has been down recently), used by
FreeHep projects. JIRA, at least as used by Tony's group, is more than a bug
tracker. For example, they add "bug reports" which are in effect to-do
items, perhaps growing out of reported problems and make use of the ability
within JIRA to express various relationships between bugs reports. In
Matt's words, they use it for "workflow management".
The demonstration
made use of VRVS desktop sharing so we could watch Tony show us around the
FreeHep JIRA pages. It worked very nicely for a while, then ceased to work
at all.
Impressions were generally quite positive. We expect to acquire and start
using JIRA.
- Release Manager: (Alex):It's taken some time to put back the
pieces after the failure of the nfs u05 RAID disk last week. This disk is
used for our external libraries and RM builds. The libraries were recovered
for us by the Computer Center. RM is nearly done with rebuilds. It is
currently hung up on rebuilding LATEST1.554 with a recurrence of the
still-unsolved problem of a test program, unable to find everything it needs
to run, but unwilling to die.
The compile and test program summary tables for newer builds like
this one now include elapsed time information.
- Install area: Toby mentioned that
GlastPolicy was modified (v5r5) to activate the install area, however
[subsequently] in
this message Traudl pointed out that many files to be installed will not
be handled by these changes.
(Traudl) Since additional changes to requirements
files will be needed for v1r16, which came out last week, she would prefer
to wait on reinstituting the Install area until we have moved to this new
version. [Post-meeting note from Traudl: she has resolved all outstanding
problems with v1r16.] She'll meet with Alex and Navid to
ensure that the new scheme takes into account features needed or desired for
release management. The aim is to come up with a migration plan which causes
minimum disruption; some broken releases are probably unavoidable. In the
meantime, those wishing to get a head start on the issues involved and likely
changes to requirements files should look at her document
Install Area: Status and plans, especially the section
Planning the migration.
- Gleam: (Toby) Recent versions of Gleam have been unable to
find tracks. This is now believed fixed; we're awaiting confirmation
on Linux.
There is no consensus on whether it is even possible in general
for us, given our use of randoms, to reproduce events. Julie has been able to
do it successfully using DC1 inputs.
- Science Tools: (Toby) No new release yet, but perhaps close. We've
run into a snag with the latest version of tip, which
will not build with VC 7.0. Could be tip just
needs some sort of fix, or alternatively, should we
- Stop supporting VC 7.0? (Toby) Are
there objections to this? (James) In principle people at Goddard should be
able to change over, but they'll need some time to do it. What about European
groups? (Leon) After his recent experience with pre-history, he recommends
that any such move be made carefully, taking time to consider exactly what
needs to be preserved so that, in the future, we can recover the current
environment easily.
-
Flight Integration: (Heather) The
weekly run-down:
- EBF (now LDF) news: (Heather)
She has built the new library on Windows, but has run into a nasty compile
error on Linux. Ric Claus has been alerted and is looking into it.
- Calibration database interface: (Joanne, Marco) Marco's
rdbGui package uses the fox library via the (new last week)
FOX interface package. fox has been built
for gcc 3.2 and installed on SLAC Linux in the standard place; rdbGui builds
and runs successfully There is still a lot of work remaining for rdbModel
and rdbGui packages.
- Diagnostic access to calibration data: (Joanne) She is working on
a small project to make it possible within the Gaudi environment to ask that
a particular calibration be loaded, even when no events are being processed.
- Document effect of MC pruning options (Riccardo) (8/5/2003) It's
documented in the code; Tracy will look into putting the information in a
more accessible place. (9/2/2003)
- Write up, and perhaps present at a future meeting, hints on debugging.
(02/18/03) Some combination of Toby and Tracy will provide
something for Windows.(7/22/03)
- Overhaul documentation altogether by about November (Heather and ??) (9/2/2003)
In progress; not yet done (01/13/04)
- Resolve calibration/timestamp issue. (11/20/02) Online folk have not yet thought about
putting timestamp information into EM data, but, thanks to Richard's
inquiry, may now do so. (2/25/03) We can probably live without a realistic
system for EM, but we will put it on the agenda for the DC1
workshop.(5/6/03) At the DC1 Workshop Steve Ritz promised to find an
authoritative reference for timestamp format and pass it on. (7/17/03) Now
that events have "real" timestamps, Joanne needs to reassess
situation with Calibration (9/2/2003) Timestamp exists in EM data. Needs to
be fetched by Calibration (1/13/04)
Put on hold until formats settle down. (3/16/04)
