Changeset 523 for XIOS/trunk/src/server.cpp

Timestamp:

Author:

Message:

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.
