Changelog

0.3.1-alpha

Date: TBA

Refined fileBased Series

A specification for Iteration padding in filenames for fileBased Series is introduced. Padding present in read Iterations is detected and honored in any further Iterations.

Changes to "0.3.0-alpha"

Features

  • CMake:
    • add openPMD::openPMD alias for full-source inclusion #277
    • include internally shipped pybind11 v2.2.3 #281
    • ADIOS1: enable serial API usage even if MPI is present #252 #254
  • introduce detection and specification %0\d+T of iteration padding #270

Bug Fixes

  • improved handling of fileBased Series and READ_WRITE access
  • expose Container constructor as protected rather than public #282
  • Python:
    • return actual data in load_chunk #286

Other

  • docs:
    • improve "Install from source" section #274
    • Spack python 3 install command #278

0.3.0-alpha

Date: 2018-06-18

Python Attributes, Better FS Handling and Runtime Checks

This release exposes openPMD attributes to Python. A new independent mechanism for verifying internal conditions is now in place. Filesystem support is now more robust on varying directory separators.

Changes to "0.2.0-alpha"

Features

  • CMake: add new openPMD_USE_VERIFY option #229
  • introduce VERIFY macro for pre-/post-conditions that replaces ASSERT #229 #260
  • serial Singularity container #236
  • Python:
    • expose attributes #256 #266
    • use lists for offsets & extents #266
  • C++:
    • setAttribute signature changed to const ref #268

Bug Fixes

  • handle directory separators platform-dependent #229
  • recursive directory creation with existing base #261
  • FindADIOS.cmake: reset on multiple calls #263
  • SerialIOTest: remove variable shadowing #262
  • ADIOS1: memory violation in string attribute writes #269

Other

  • enforce platform-specific directory separators on user input #229
  • docs:
    • link updates to https #259
    • minimum MPI version #251
    • title updated #235
  • remove MPI from serial ADIOS interface #258
  • better name for scalar record in examples #257
  • check validity of internally used pointers #247
  • various CI updates #246 #250 #261

0.2.0-alpha

Date: 2018-06-11

Initial Numpy Bindings

Adds first bindings for record component reading and writing. Fixes some minor CMake issues.

Changes to "0.1.1-alpha"

Features

  • Python: first NumPy bindings for record component chunk store/load #219
  • CMake: add new BUILD_EXAMPLES option #238
  • CMake: build directories controllable #241

Bug Fixes

  • forgot to bump version.hpp/__version__ in last release
  • CMake: Overwritable Install Paths #237

0.1.1-alpha

Date: 2018-06-07

ADIOS1 Build Fixes & Less Flushes

We fixed build issues with the ADIOS1 backend. The number of performed flushes in backends was generally minimized.

Changes to "0.1.0-alpha"

Bug Fixes

  • SerialIOTest: loadChunk template missing for ADIOS1 #227
  • prepare running serial applications linked against parallel ADIOS1 library #228

Other

  • minimize number of flushes in backend #212

0.1.0-alpha

Date: 2018-06-06

This is the first developer release of openPMD-api.

Both HDF5 and ADIOS1 are implemented as backends with serial and parallel I/O support. The C++11 API is considered alpha state with few changes expected to come. We also ship an unstable preview of the Python3 API.
