  1. Status and Plans LIGO-G070364-00-Z Software Management

  2. Software Management Relevant Areas Software Version Control Development Environment Problem Report Releases and Distributions

  3. Software Version Control • Based on CVS with pserver remote access. • Provided also an alternative use mode via SCVS, a very thin layer on top of CVS aimed to simplify its use and tailor it on the Virgo Software development specificity. • CVS archive accessible via WEB at: http://wwwcascina.virgo.infn.it/cgi-bin/cvsweb/cvsweb.cgi • Status • The Virgo Control SW is almost all stored in the Cascina archive. • Few Data Analysis software packages still missing.

  4. CVS Software Archive Statistics

  5. Development Environment • A standardized development essential requirement to manage different people in different sites. • Such standardized environment has been obtained using the tool CMT • CMT provides all key elements of a development environment: • structured make usage • easy encapsulation of third party tools and libraries • standardization of the UNIX environment set-up of every Virgo user. 5

  6. Software Problem Report (SPR) • Provides an easy standard avenue for users and testers to report bugs and for developers and maintainers to fix them and track them in an orderly fashion. • Very simple interface and SPRs lifecycle to avoid that developers end up in spending more time on the bug tracking system than on the bugs or the projects themselves. • A central database with Web and email interface to submit, query, modify SPRs (implemented using WREQ) • Available at: • http://pub2.virgo.infn.it/cgi-bin/wreq/req 6

  7. Software Problem Report Statistics Received: 702 Closed: 561 Still Open: 141

  8. Releases and Distributions • Slow upgrade cycle (3-6 months) for Major Releases, on demand for Minor Releases • Tested for non-regression • Uniquely identify all components (O.S., tools, external packages, Common Software) needed as development or operational platform of an application. • Provide the explicit Integration Plan • Heavily relying on the Virgo Test Facility (VTF) for the build and test phase • Definition and distribution of five releases, from VCS-1.0 (Feb 2004) to VCS-5.0 (Mar 2007) • Since the beginning of VSR1 marked a turning point for the Virgo Software a separate Data Analysis Release cycle and Distribution (disentangled from the Control Software one) is under definition 8

  9. Software freeze for VSR1 • For all the code in operation during the Science Run on the interferometer (including on line Data Analysis running on site and DSP Code) stable code is to be frozen • Status: • Injection, Suspension, EnvMon, Vacuum, Gc frozen on top of VCS-5.0 baseline • DAQ, Detection, Detector Monitoring frozen on top of a newer set of basic packages • Still ongoing: • freeze of Online Data Analysis chain • Few remaining (hopefully!) minor fixes and installations • It should be worth introducing a VCS-5.1 as the snapshot of the VSR1 software and for CMT dependencies cleanup • For the Data Analysis distribution to be derived it would be important upgrade all Virgo depending tools to root v5.14.00
