[Unreleased]

[1.16.1] - 2025-02-06

Fixed

Reverted use of c_bool in MpiLock.F90. Was causing issues with some compiler/MPI combinations.

[1.16.0] - 2025-02-03

Added

LLVMFlang compiler support
- NOTE: Issues between LLVMFlang, MPI, and linktime mocking means for now the tests are not built with LLVMFlang

Changed

Modified CMake logic to build entirely separate library (pflogger-with-mock) to support testing with mocks. Previous cheat to link pflogger against real MPI for runs but mock MPI for tests did not work with LLVM. Seems to be due to some encryption type protection on module info.
Update CI to have gfortran-10 and gfortran-11 only on ubuntu-22.04
Update CI NVIDIA to NVHPC 24.7
Add Flang to CI

[1.15.0] - 2024-05-17

Changed

Change use of spread in MockMPI.F90 initialization to reshape to avoid NVHPC issue

[1.14.0] - 2024-03-26

Fixed

Workaround additional polymorphic assignment bug in gfortran 13.2 (in build_locks)

Changed

Added -quiet flag for NAG Fortran

[1.13.2] - 2024-03-13

Fixed

Another fix for MockMpi layer. With the workaround for NAG in previous release, GFortran 13 detects some inconsistencies that are now resolved.

[1.13.1] - 2024-03-07

Fixed

Fixed problem encountered due to recent changes in NAG and/or OpenMPI broke the kludge that supports use of a mock MPI layer for testing locks within pFlogger.

[1.13.0] - 2024-03-03

Added

Fujitsu compiler support

Changed

Updated dependency on yaFyaml to 1.2.0 as a workaround to gfortran 13.2 bug with polymorphic assignment.

[1.12.0] - 2024-01-25

Changed

Add new ENABLE_MPI option to allow disabling MPI support (#106). By default, MPI is enabled to maintain backward compatibility.

[1.11.0] - 2023-11-29

Fixed

Workarounds for MPICH C_LOC missing interface (pmodels/mpich#6691)
Add -check nouninit for Intel LLVM to work around ifx bug.

[1.10.0] - 2023-04-17

Added

Added IntelLLVM.cmake file as a copy of Intel.cmake to support the LLVM Intel compiler frontends

Changed

Updated required version of gFTL to v1.10.0
Updated required version of gFTL-shared to v1.6.0
Updated required version of yaFyaml to v1.1.0

[1.9.5] - 2023-04-13

Changed

Added Intel to GitHub Actions

[1.9.4] - 2023-04-12

Fixed

Formatter logic to get simulation time was broken if the default date format is used.

[1.9.3] - 2023-01-25

Fixed

Package was incorrectly assuming that all extant compilers support 128 bit reals. Now a check is performed to optionally include support for 128 bit reals.
Fix Parser() declaration for Intel 2021.7

[1.9.2] - 2023-01-23

Fixed

Fixes for GNU Make builds

[1.9.1] - 2022-05-31

Updated GitHub Actions
- OSs
  - Remove macos-10.15
  - Add ubuntu-22.04 and macos-12
- Compilers
- Removed gfortran-8
- Added gfortran-11
- Added gfortran-12 (for ubuntu-22.04)

Fixed

Workarounds in tests for NAG 7.1 (7110)

[1.9.0] - 2022-05-08

Fixed

Introduced workaround for gFortran when combining strings with unlimited polymorphic entities. Users may be able to avoid using a String() wrapper for args to logging commands now.
Cleaned up some stray debugging prints
Fixed misspelling of SUCCESS

[1.8.0] - 2022-04-08

Changed

Updated to new version (1.0-beta7) of yaFyaml which involves new interfaces.

[1.7.0] - 2022-03-24

Added

Add NVHPC.cmake and PGI.cmake files for NVHPC support

Fixed

Implemented workaround for gfortran 11.2 that was breaking on a surprisingly simple call.

Changed

upgraded to use new gFTL2 interfaces for containers.

[1.6.1] - 2021-11-17

Changed

now under the Apache 2.0 license

[1.6.0] - 2021-09-28

Changed

updated to use yaFyaml 1.0 (new interfaces in yafyaml, not pflogger)

Fixed

Ability to embed pFlogger alongside the other GFE libraries in a superproject.

[1.5.0] - 2021-03-15

Added

Pervasive return codes for all procedures with potentially failing branch. Added as optional arguments for backward compatibility.

Changed

Introduced CMake namespace. Upstream projects should now specify dependency as PFLOGGER::pflogger

[1.4.5] - 2020-08-24

Changed

Fixed one more test that was missed in previous update. (Was using -f filter to focus on some failing tests. Blinded to thore tests.)

[1.4.4] - 2020-08-23

Changed

Recent addition of basic_config() (see previous release) introduced an ambiguity for memory management. The underlying design from Python is based upon garbage collection and reference counting. To solve this problem there the user can now either specify a HandlerVector or a HandlerPtrVector (but not both) If the former, pFlogger will copy the handlers into its internal storage. If the latter, pFlogger will only retain a pointer reference to the user actual argument. In that case, the user is repsonsible for maintaining the handlers until pFlogger is finalized and ensuring that any locks are freed.
The argument to Logger::add_handle() must now have the TARGET attribute. pFlogger will only maintain a pointer to that target. This is to be consistent with the above strategy.

Fixed

Implemented workaround for ifort 18.0.5 that became necessary after the changes above. Only impacted unit tests.

[1.4.3] - 2020-08-07

Fixed

Some flavors of MPI complained at finalize because the MPI memory windows were not freed. Fixing required nontrivial changes because handlers (and thus locks and windows) were unintentionally duplicated rather than shared among logger objects.

[1.4.2] - 2020-05-20

Changed

Modified name of Pair type in gFTL maps. These are not used within pFlogger outside of their host modules, but it is more consistent with the latest gFTL-shared and may help anyone that tries to port with XLF.

[1.4.1] - 2020-05-01

Added

Added free() methods to various classes to ensure that MPI resources are deleted at the end of the run. Without this, some MPI flavors will report an error on MPI_Finalize(). To use:
```
 call logging%free
```

[1.4.0] - 2020-04-17

Added

Added basic_config() method for LoggerManager analogous to that of Python's logger.
Also added overload of get_logger() with no name argument which returns the root logger. (Again as per Python.)
Added example/basic_config/basic_config.F90 (requires MPI)

Fixed

minor bug in default fmt_ for MpiFormatter "rank" should have been "mpi_rank".

[1.3.6] - 2020-04-16

Fixed

Trivial change to allow building with older compiler (ifort 17.0.4)

[1.3.5] - 2020-04-13

Fixed

Mostly workarounds for gFortran
Also corrections for Cmake for some configurations

[1.3.4] - 2020-04-08

Added

Added a "last resort" handler for when no handlers are found. (ala Python's logger)

Fixed

A problem with link-time dependency injection for mock MPI was fixed with generator expressions. Previously the fix for tests broke the examples

[1.3.3] - 2020-04-06

Changed

Must use true/false instead of .true./.false. for YAML

Fixed

Fixed CMake test for support of MPI_ALLOC_MEM
Improved Cmake handling of mock to allow tests to compile without linking to MPI
Added missing init() in Test_MpiLock tests

[1.3.2] - 2020-03-16

Fixed

Cmake installation was using the wrong macro
allow longer lines (GFortran)

[1.3.1] - 2020-03-11

Bugfix

Added

Changed

Fixed

Needed to enable cmake testing.

[1.3.0] - 2020-03-11

Using FindPackage to find pFUnit (not required)
Updated to pFUnit 4.0
Changed naming conventions for modules (dropping the _mod suffix)
Introduced dependency on gFTL-shared . eliminates redundant code . makes container types are consistent across projects
