  • correct unlock in input source at the end of the run
  • "Failsafe" is set as JSON stream destination field in case of unsucessful determination with HLT menu and selected transfermode
  • renamed reserved TCDS FED header variable to triggerTypeFlags
  • support for Intel acceleration of CRC-32C with new FRD v5 (replaces adler32)

@smorovic
triggerTypeFlags bitmask (was reserved4) in TCDS header interface

@smorovic
lock --> unlock (not critical as process exits and releases the lock …

…shortly after)
@smorovic
*added SSE 4.2 accelerated CRC32-C
b4bb683 
 Original implementation by Mark Adler patched to compile as C++ and
 introduced ifdefs to compile SSE 4.2 asm version only for X86_64,
 otherwise using fallback to software crc32c implementation
*changes to support checking crc32c checksum in both raw input sources (V5 of the FRD format),
 included also support for V4 header
*ability to generate new FRD v5 format and checksum with fakeBU script
@smorovic
use "Failsafe" as reserved destination name when sdestination can't be
4215d7c 
calculated instead of empty string.

Comparison is ready
https://cmssdt.cern.ch/SDT/jenkins-artifacts/pull-request-integration/PR-8908/4512/summary.html

The workflows 140.53 have different files in step1_dasquery.log than the ones found in the baseline. You may want to check and retrigger the tests if necessary. You can check it in the "files" directory in the results of the comparisons

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_4_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
