This version of artdaq_core can be built against art v1_12_01, v1_11_03, or v1_10_00b. However, the standard distributions on SciSoft only include builds with art v1_12_01 and v1_11_03.

It can also be built with gcc v4_9_1 or v4_8_2. However, the distributions on SciSoft only include builds with gcc v4_9_1.

For reference, the e6 build qualifier indicates gcc v4_9_1, and e5 indicates gcc v4_8_2.

The s5 qualifier indicates art v1_12_01, s4 indicates art v1_11_03, and s3 indicates art v1_10_00b.

External Package Changes

artdaq_core v1_04_05

The v1_04_xx series of artdaq_core releases so far has moved rather quickly. So, all of the changes since v1_03_05 are listed here, even though some of them became available in earlier v1_04_xx releases.

New features:

  • The Utilities classes (SimpleLookupPolicy and TimeUtils) were moved from the artdaq package into artdaq_core.
    • This was needed in order to split ds50daq into two packages (Issue #6192: Move the data format classes to a separate package so that darkart would not need to depend on ds50daq)
  • The artdaq::Fragment class was modified to internally use a new custom vector class.
    • This is part of Issue #4655: Possible performance enhancement to Fragment
  • The model for storing package version and build time information in the data files has been improved and simplified.
    • More information can be found here.
  • An optional timestamp parameter was added to the start/stop/pause/resume commands that are sent to the system to support the synchronization of all parts of the system (initially for LBNE).
    • This is part of Issue #6783: Add timestamps to Init, Start, Stop, Pause, and Resume commands
  • An optional timeout parameter was added to many of the commands that are sent to the system.
    • This will be needed when we get to Issue #5330: Add timeouts to the execution of XMLRPC commands. This change was made now since it was very similar to the one that added timestamps to the start/stop/pause/resume commands.

Bug fixes:

  • none

Operational changes:
