Hello everyone,
Stefan and I have make a few updates to mplot to clean up some of the code and make it more usable directly from Javascript. With one exception

Due my oversight, the code for extracting ODB dumps from MIDAS data files from rootana/old_analyzer/event_dump.cxx was missing in
manalyzer.cxx.

Dear all, I implemented an optional timeout for the wait ODBvalue command. The way it works is similar to the standard wait command:
WAIT ODBvalue, /Equipment/HV/Variables/Measured[3], <, 100, timeout, 60

|
I've been working on updating MIDAS' testing suite. It is yet incomplete, but the basic structure is there. Once the code coverage reaches a
more acceptable level and it is decided that the new tests are good replacements to the existing tests, it will be merged into develop.
Tests are located in $MIDASSYS/tests directory in the automated_testing branch. |
