This is a bugfix release with just a couple of minor backward compatible improvements.

We also updated the LCG baseline version to LCG 97a (ROOT 6.20/06).

This is the last release with the legacy CMake configuration. From the next release (v34r0) we will use a modern CMake configuration (see !922 and !986 for details).

This is a bugfix release only to fix a warning with the most recent version of CMake (3.13), see the changes on Gitlab.

The main reason for this major release is to the change of the Algorithm base class with a re-entrant execute method (#47, !703). For backward compatibility the base class for algorithms is Gaudi::Algorithm, while the name Algorithm in the top level namespace is used for a backward compatible implementation. This change also required a backward incompatible change in the IAlgorithm interface, so some code may require adaptation.

We also took the occasion to update the version of clang-format we use from 3.9 to 7, and to switch Python formatting from autopep8 to yapf (!788). Because of the differences (fixes and new features) in the versions of clang-format, we also updated the style rules.

As of this version, Gaudi requires C++17 compatible compiler. C++14 compatibility is not required in merge requests, nor guaranteed on the master branch.

On top of that, we have the usual collection of minor fixes and improvements.

Changed

• Use gcc 8 instead of gcc 7, and drop gcc 6.2 in CI jobs (!836)
• Make new counters work with Gaudi::Algorithm (#57, !834, !839)

• Make DataObjectHandle::{put,getOrCreate} const (!833)
• Simplify IAlgExecStateSvc interface (!775)
• Simplify Algorithm constructor (!766)
• Improve the scheduler's execution flow simulator and fix the intra-event occupancy logger (!819)
• Reentrant Algorithm base class (#47, !703)

Added

• Introduced CPUCrunchSvc (!840)
• Added a boolean parameter to turn on verbose view algorithm status (!835)
• Added MsgStream support for counters (!826)
• Message: Add option to print full event ID (!824)
• IoComponentMgr: Add interface to retrieve all filenames of component (!823)
• Add example for Consumer<void()> (!797)

Fixed

• Fix lookup/use of nosetests for LCG 95 (!842)
• Check coding conventions in build stage of Gitlab-CI (!848)
• Make gaudi_add_compile_test also work for succeeding compilations (!844)
• Fix build of Gaudi with LCG 95rc1 in ATLAS context (!847)
• Explicitly define StatusCode constants (!841)
• Fix handling of EventContext in Gaudi::Functional::Transformer arguments (!837)
• Extensions to allow EventIDRanges limited by both time-stamps and run/LB pairs (!831)

• Improve QMT test wrapper (!812)
• Improvements for tests (!812, !817)

• Code clean up (!808, !811, !814, !809, !827, !843)
• Fixes to thread local initialization (!816, !807)

This release is mainly to revert !462 (Reimplemenation of DataHandle), which caused problems in ATLAS code.

Supersedes v30r4

Changed

• refer error in databroker when multiple algorithms declare the same output and remove some error messages (!799)
• Remove redundant code from GaudiKernel/StdArrayAsProperty.h (!790)
