source: XIOS/branchs/xios-1.0/src/server.hpp @ 548

Last change on this file since 548 was 548, checked in by rlacroix, 8 years ago

Backport r523 into the stable branch.

Improve the message error handling by mimicking the behavior of the info/report logs.

Output the error messages to the standart error message until the context is correctly initialized. Then, output the error messages to a file if the user has set "print_file" parameter to "true".

  • Fix: Errors that occured before MPI was initialized (e.g. during the config file parsing) caused a MPI error on top of the original error.
  • Fix: The error file could sometimes be misnamed if the error happened before the context was completely known.
