Reasons for change

• centaurusa is going away, and we need to maintain "live" ("modifiable") versions of all L1Proc packages
• several L1-related packages are still using stag, which is: a) not actively maintained c) not available on s3df
• github has modern gui, tools, etc. making maintenance a lot easier down the line (branching/versioning/etc.)

CCB Jira:

Test Procedure

All packages listed below are available on github, and can be downloaded and compiled on S3DF 

Rollback procedure

No rollback is planned/desired. Additionally, this change will become irreversible once centaurusa is retired

Migration workflow

• Goal: move all individual L1 packages to the fermi-LAT github space: https://github.com/fermi-lat
• Method: use these instructions by JimC: https://github.com/jchiang87/asp_migration/tree/main/cvs_to_git
• On the github side (after migration): make all packages public, but protect tags and branches

Why make all packages public

• this is consistent with Fermi-LAT practice
• authentication to a git server via container is not trivial
• increase transparency, increment bus-number from one  

Archiving "umbrella" packages

• L1 uses two "umbrella" packages:
  • svac (contains: findGaps, L1Pipeline, Monitor, TestReport)
  • dataMonitoring (contains: Common, FastMon, AlarmsCfg, etc.)

• this does not translate well to the flat structure of our gitlab repository
• additionally, both packages contain lots of obsolete code
• plan: migrate those packages as a whole to github, and archive them

• svac (contains: findGaps, L1Pipeline, Monitor, TestReport) → archived to svac
• dataMonitoring (contains: Common, FastMon, AlarmsCfg, etc.) → archived to dataMonitoring

Individual repositories that were migrated

• L1Pipeline (single package, previously in svac) → migrated to L1Pipeline
• findGaps (single package, previously in svac) → migrated to findGaps
• TestReport (single package, previously in svac) → migrated to TestReport
• Monitor (single package, previously in svac) → migrated to Monitor
• pipelineDatasets (obsolete, previously under users/richard) → archived to pipelineDatasets
• evtClassDefs (single package, may be needed needed by others) → migrated to evtClassDefs

• GPLtools (single package, actively being modified for s3df use) → migrated to GPLtools

• Common (single package, previously in dataMonitoring) → migrated to Common
• DigiReconCalMeritCfg (single package, previously in dataMonitoring) → migrated to DigiReconCalMeritCfg
• FastMon (single package, previously in dataMonitoring) → migrated to FastMon
• FastMonCfg (single package, previously in dataMonitoring) → migrated to FastMonCfg
• IGRF (single package, previously in dataMonitoring) → migrated to IGRF

Repository to be migrated in parallel

• AlarmsCfg (single package, currently in dataMonitoring → migrated to AlarmsCfg (see )
