Revision Log
| Sticky Revision: |
Bit more work on IPOPT presolve and hessian calculation. Added export of relman_jacobian_count.
Fixed external loading of integrators, at least on my system. Needs testing with/without fortran, sundials, etc. Changed little thing kn d1mach.c to make default behaviour correct on Linux.
Fixed missing symbol exports for building on Windows. External solvers are working fine in the PyGTK interface. A bug appears to be present in the Tcl/Tk interface.
Moved all solvers to dynamically loaded modules currently in folder models/johnpye. Location of these files will ultimately change.
Another one of these big refactorings. Split out 'system' directory from 'solver' directory. This will need more work but it's a start at getting the non-solver-specific code out separately.
Added index checking for semi-explicit DAE systems. Migrated error messages for mtx and linsolqr to the error_reporter mechanism.
Reversing changes to relman.[ch] (they broke CONOPT)
Added getParameter by name in SolverParameters. Fixed up refences to signal-related header files. Fixed up various warnings from -pedantic compilation. Identified an apparent bug with RelationCalcGradient (unsafe version). Added support for compilation of a standalone C++ program (idatest) in SCons build.
Implemented the DAE partitioning routine but am nowing tracking down a fiendish memory crash.
Huge reorganisation -- all mtx and lin files moved to base/generic/linear. Required many #include statements to be changed.
Adding doxygen 'addtogroup' for Solver, Compiler, Integrator.
Changed ASC_DLLSPEC(TYPE) to ASC_DLLSPEC TYPE, because it was causing havoc with doxygen and ctags.
Added VAR_DIFF and VAR_DERIV flags to var_variable type. Added flagging of variables as such during integrator_analyse_dae. Cleaned out some old guff from the mtx* headers.
Added finite-difference evaluation of gradients in blackboxes. Some work on J*v evaluation with IDA.
first attempt at merging with Ben's changes on the trunk
Fixed relman_diffs to make call to ExtRel_Diffs_RHS and _LHS (this is a bad hack though, just to get the old code working again).
Merged changes from DAE branch (revisions 702 to 819) back into trunk. This adds the Integration API to the ASCEND solver (in base/generic). Also provides pre-alpha support for 'IDA' from the SUNDIALS suite, a DAE solver. Many other minor code clean-ups, including adoption of new 'ASC_NEW' and friends (to replace 'ascmalloc') Added some very sketchy stuff providing 'DIFF(...)' syntax, although it is anticipated that this will be removed.
Fixed all the missing symbols so that ASCEND Tcl/Tk interface builds with separate 'ascendtcl.dll'. Split Driver.c across Driver.c and new main.c, which has no Tcl/Tk references.
got rid of errant executable bits.
Standardised the "if seen" #defines to [ASC|ASCTK|ASCPY|ASCXX]_FILENAME_H Fixed compile on FC3
Manual rework of doxygen comments in all headers. - Added @file comment to all headers. - Added parameter names to all function declarations in headers. - Corrected comment referencing where necessary. - Split some comments which documented blocks of declarations. - Converted notes about required work into @todo comments so doxygen can generate a todo list. Minor bug fixes.
First pass at doxygenation -- mechanically putting in ** and where most likely needed **< using sed. Lots of cleanup needed to be really useful, including grouping data types and their member methods into class-like documentation.
moving things to base/generic
