v38r1 - 2024-03-15

This backward compatible release of Gaudi features a few fixes and improvements, and a major step towards some proper polishing an refreshing of the examples.

The GaudiExamples directory started as a place to host examples, but evolved in a collection of tests. Examples should be tested, of course, but we ended up keeping there tests for backward compatibility with legacy code that were not meant to be used as examples (see gaudi/Gaudi#254). With this release GaudiExamples becomes GaudiTestSuite, leaving the room for development of proper examples. For backward compatibility we kept some of the exported classes, which are considered deprecated and will be removed in v39r0 (see gaudi/Gaudi#293).

Changed

  • Rename (Gaudi)Examples to (Gaudi)TestSuite (gaudi/Gaudi!1557)

  • Fix node properties in PrecedenceGraph, update precedence related scripts (gaudi/Gaudi!1560)

  • GaudiPython: sort set properties before storing in catalogue (gaudi/Gaudi!1549)

Added

  • Add the possibility to have variable bin size in Monitoring histograms (gaudi/Gaudi!1564)

  • Add a .git-blame-ignore-revs file with a few formatting commits (gaudi/Gaudi!1558)

Fixed

  • More reliable handling of \n in test stdout diff (gaudi/Gaudi#291, gaudi/Gaudi!1563)

  • Reset std::hex immediately (gaudi/Gaudi!1555)

  • Use fmt::runtime when compiling with GCC 11 (gaudi/Gaudi!1559)

  • Make reproducible_write test work when GAUDIAPPNAME is set (gaudi/Gaudi#290, gaudi/Gaudi!1562)

  • Fixed behavior of reset in Monitoring Hub (gaudi/Gaudi!1552)

v38r0 - 2024-01-25

This new major release includes a number of small/technical backward incompatible changes (meaning that you may or may not be affected by them depending of which parts of Gaudi you use), but also a couple of more visible changes:

  • GaudiAlg is not built anymore by default, but still present and will be removed in a future release

v37r0 - 2023-09-14

This is the first major release of Gaudi in a while. This was made necessary to be able to incorporate a number of backward incompatible changes that have been kept in the backburner until now.

The main (backward incompatible) changes are:

  • clean up and improvements to the new monitoring infrastructure

    • custom sinks have to be adapted

  • drop of LIKELY and UNLIKELY preprocessor macros

    • they have been deprecated for long, but waiting for a major release to effectively remove the implementation

  • make the subdirectory GaudiAlg optional

    • still enabled by default, it’s not really backward incompatible, but the refactoring implies that some minor adaptations might be needed in downstream code

Since this a major release we took the occasion to update the versions of the hooks in pre-commit-config.yaml and that caused some minor changes in the formatting.

In addition we have the usual batch of fixes and some new features.

Changed

  • Update versions in pre-commit hooks (gaudi/Gaudi!1415)

  • Remove old warning message referring to CMT (gaudi/Gaudi!1486)

  • Update and simplify gitlab-ci (gaudi/Gaudi!1476)

Added

  • Added support for the HepPDT vesion 3 (gaudi/Gaudi!1488)

  • Fix TTree output reading in tests (gaudi/Gaudi#273 gaudi/Gaudi!1489)

  • Use inspect.signature (if possible) instead of the deprecated getargspec (gaudi/Gaudi!1485)

  • Fix performance of Counter destructor by using appropriate containers in Sink (gaudi/Gaudi!1477)

  • Hide RdtscClock.h to non x86_64 builds, needed for aarch64 (gaudi/Gaudi!1479)

v36r16 - 2023-07-28

Release requested by LHCb to backport gaudi/Gaudi!1478

Added

  • Fire ContextIncident CONNECTED_NTUPLE_OUTPUT when opening a ntuple file in RFileCnv (gaudi/Gaudi!1482)

v36r15 - 2023-07-24

This release is needed so that LHCb can pick up a backward compatible version of gaudi/Gaudi!1477.

Fixed

  • Fix performance of Counter destructor by using appropriate containers in Sink (adaptation of gaudi/Gaudi!1477)

v36r14 - 2023-06-19

This release features a number of minor fixes to help downstream projects work with C++20, plus a few minor fixes.

Changed

  • Make sure OutputStream instances are configured with and explicit Output option (gaudi/Gaudi#262 gaudi/Gaudi!1467)

Added

v36r13 - 2023-06-05

This is a minor bugfix release needed by LHCb to pick up some additions.

The most interesting changes in this release are:

  • fixes to Python code addressing flake8 reports (now flake8 is also in the pre-commit hooks)

  • fixes to be able to compile with C++20

  • fixes to be able to run on macOS (some usability improvements are still needed, but no blocker left)

  • Fix genconf on macOS (gaudi/Gaudi!1406)

v36r12 - 2023-03-20

Another minor release requested by LHCb. The main change is that now OutputStream creates the output file during the start transition instead of when trying to write the first selected event. This means that output files might be created and left empty rather than not created. The rationale for this change is to have a more predictable behaviour (one that does not depend on the job details).

Changed

  • Always write output files (gaudi/Gaudi!1432)

Added

  • GaudiConfig2: add clone for Configurable (gaudi/Gaudi!1433)

Fixed

  • GaudiKernel: flake8 fixes (gaudi/Gaudi!1434)

Added

  • Adds CheckedNamedToolsConfigured functionality (gaudi/Gaudi!1424)

Fixed

  • Fix log file messages when using Histograming::Sink::Base (gaudi/Gaudi!1426)

  • Update version of isort used in pre-commit (gaudi/Gaudi!1429)

v36r10 - 2023-02-14

This is a small maintenance release focusing on fixing bugs. In particular we fixed a number of issues affecting builds on MacOS.

There are a few changes that should be mostly transparent from the code point of view, but may produce slightly different printouts.

Changed

  • Use python3 instead of python (gaudi/Gaudi!1418)

  • Use MessageSvc to handle ROOT messages (gaudi/Gaudi!1412)

  • Fix gcc12 warnings (gaudi/Gaudi!1403)

v36r9p1 - 2023-02-03

Strictly identical to v36r9 (except for the version number), needed by LHCb for a special deployment.

v36r9 - 2022-11-21

Just some minor bugfixes and a few (mostly backword compatible) changes in behaviour.

To be noted:

  • ROOT file produced by RootCnvSvc are now more reproducible (gaudi/Gaudi!1380), thanks to a special flag from TFile, in case of problems or for backward compatibility the new behaviour can be turned off with the RootCnvSvc property ProduceReproducibleFiles (dafalt is true)

  • RootCnvSvc improves compressibility of files by using larger basket sizes (see gaudi/Gaudi!1381), the side effect is that one may notice al larger use of VMEM from the job

  • we added a few missing const in LinkManager interface (gaudi/Gaudi!1386), but that means that downstream code might fail to build if it was relying on const instances returning pointer to non-const objects

  • you will get a runtime error when trying to create histograms with heading or trailing whitespaces in titles and labels (gaudi/Gaudi!1397)

Changed

  • Create reproducible ROOT files and clean up tests (gaudi/Gaudi!1380)

This is a bugfix release with a couple of changes that technically are backward incompatible because they fix issues that might have gone unnoticed:

  • gaudi/Gaudi!1265 makes the property parser throw an exception in case of problems, instead of silently doing nothing (see gaudi/Gaudi#163)

  • Gaudi::Accumulators counters were copiable but not movable, which was not correct: they should be neither and we fixed it, but this means you cannot use them in vectors and the postfix ++ operator has been removed

An interesting addition in this release is also the support for getting AlgTools as arguments to the operator() of Gaudi::Functional algorithms. Although it might seem strange at first, it allows reducing boilerplate and opens the possibility of introducing tool wrappers that bind a tool with event or condition data, so that the fact that a tool needs some event data is both explicit (event data has to be passed to the tool methods) and hidden from the end user (as the wrapper takes care of the details of data passing).

After the introduction of pre-commit support (gaudi/Gaudi!1261) the merge request review became more difficult as the reformatting of changed files add too much noise, so in this release we reformatted the code with clang-format-11 for C++ and Black+isort for Python (see gaudi/Gaudi!1286).

v29r5 - 2019-03-06

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

v31r0 - 2019-02-11

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)
