HELICS v2.7.1 Release Notes

Release Date: 2021-06-03 // almost 3 years ago

  • 🚀 There were several bug fixes in this patch release. Some of them related to changes in [2.7.0][] and some new ones that came up from bug reports. Some new enhancements are experimental signal handlers in the C-api, which will be used in the python interface to provide a little better user experience when trying to kill a co-simulation.

    🔄 Changed

    • String output on recorders is now always JSON compatible and allows escaped characters. This allows some additional values to be displayed in ascii format vs base 64 encoding. #1910
    • 📜 Players read the string fields through a JSON parser unless marked with b64[] to match the string output on recorders #1910
    • 🏁 The default webserver port is now 8080 to allow user space execution on non-Windows platforms #1936

    🛠 Fixed

    • An issue with recorders writing text fields in the incorrect order which could result in incorrect playback #1910
    • 🛠 Fix an issue with core naming that occasionally resulted in same broker name errors when using default names on federates #1919
    • 🛠 Fix an issue where queries were not being resolved when a core disconnects which could result in deadlock. #1931
    • The wait_for_current_time flag was not working properly in some cases where time interruption was also taking place #1933
    • 🛠 Fixed issue with the webserver not responding with the index page when requested or detecting the correct broker for certain trivial requests #1936

    ➕ Added

    • 🚦 Signal handlers for catching SIGINT and optional user callback are available in the C shared API #1915
    • ➕ Added support for environment variables for setting some network connection settings and other information #1921
    • Queries now have timeouts #1931
    • 💻 Command line and environment variable options for setting the webserver port numbers #1936
