Agenda

Short Term (2021APR / 2021JUN)

• Maintenance (Bug-fixing / Improvements)
• Obsolescence Management
  • Integrate 2021FEB Work on obsolescence
  • Tcl/Tk – 2021FEB
    • Considering waiting on RHEL / CentOS 8 upgrade, to remove the dependency altogether due to complex compilation process
  • Python3 (8 packages) – 2021APR
  • Java (8 packages) – 2021APR
  • Move External Dependencies (Some of ACS' Tools) out of ACS build and into ExtProd
    • cppunit was moved as part of 2021FEB for testing out along with searchFile script and C++, Python and Java counterparts improvements to look into the new path ($ALMASW_INSTDIR/ExternalDependencies)
    • Other tools will start being moved – 2021APR
• Generate Maven Artifacts for ACS Jars
  • Done in 2021FEB for local repository
    • New target 'deploy_all' was added to upload artifacts to maven repository
  • Discuss appropriate ways to configure the destination repostiroy for artifacts (Env variable, Maven settings.xml, etc.) – 2021APR
• C++ Modernization – Threading – 2021JUN
  • (Ralph) I asked NRAO developers and none of them is waiting for this.  It's can be done at a later time.
• Summer Internships
  • BulkData Alernative (ZeroMQ-based) – ongoing
  • Notification Channel Alternatives (Investigate Technologies) – ongoing
  • Evaluate feasibility of integrating the results as part of ACS – 2021JUN/2021AUG)

Mid Term (2021AUG --> 2021DEC)

• RHEL 8 / CentOS 8 Coordination
  • Roll-out a plan and discuss the feasibility of making the software compatible with RHEL 7 and 8 by Cycle 9
  • There are some constrains with kernel module development which may push the change to Cycle 10
• ACS C++ Modernization (Choose one topic: SmartPointers, Logging) – Likely 2021OCT/2021DEC

Long Term (TBD)

• ACS Makefile Refactoring subsystems coordination
  • (Ralph) Can the ability to build the common software i.e., ACS, ICD & ARCHIVE using the new Makefile be added to the short term goals. That will allow subsystems that are waiting for this, like CONTROL, to get started in 3Q2021.
• ACS C++ Thread modernization – ~2021JUN
• Redesign C++ Logging
• Java Modules

Other Input

Parsing XML in Java.

The Castor package is provided to parse XML in Java. We use a version that is 16 years old. The latest version is 6 years old and is no longer supported. I suggest we update to the latest version for 2021APR and plan to change to something currently supported, like JAXB, later in 2021.

Not Relevant
