Revision 1049 - (hide annotations) (download) (as text)
Fri Jan 5 13:45:13 2007 UTC (12 years, 11 months ago) by johnpye
Original Path: trunk/pygtk/test.py
File MIME type: text/x-python
File size: 19651 byte(s)
Changed integrator_solve to return 0 on success
Changed integrator_checkstatus to return 0 on success
Some flow-through changes as a result of these.
Fixed problem with reporting of errors in do_method (gtkbrowser.py)
Expanded error msg in integrator.cpp
Fixed catching of Integrator C++ exceptions in integratorreporter.py.
Removed M.checkStructuralSingularity() in TestSteam.testdsgsat -- causes crash (why?)
