Effect of #VSCP package change

For those of you running head code of the VSCP & Friends package

Remember to build the full VSCP & Friends package after checking it out from git and then compile all files and do a “make install” as root. If you don’t do this drivers and the VSCP server (the daemon) may use different package formats which will   corrupt memory and probably make the VSCP server and the rest of the code unstable.

IMPORTANT! #VSCP configuration change

From version 1.12.24.0 Magnesium the configuration file format has changed. A lot of things have moved out from the <general> section up to the top-level.  Refer to the distribution vscpd.conf for full info.

Configuration file reading order has changed as well. Now things work as the following

  1. Read the <general> tag information from the XML configuration.
  2. Read configuration from the database.
  3. Read the full XML configuration.

This change makes it easier to have a safe setting in the XML configuration file that can’t be overwritten by changes in the database. The importance of this will be more clear when settings can be changed in the administrative web interface.

REMEMBER TO DELETE DATABASE FILES AFTER A NEW BUILD.

Cheers

ps There is a lot of bumblebees here on the VSCP hill right now, more than ever before. Must be a sign… 😉 ds
