There + are no known bugs, but bugs almost certainly exist. This pack needs systematic in-depth testing for subtle issues + connected to garbage collection. Specifically, the mechanism to call Icon from C++ pushes onto the top of the Icon + stack a region used by a copy of the interpreter loop that's used to execute the Icon procedure called from C++. + I have not investigated how the Icon stack is garbage collected, and this region does not extend the stack the + way that Icon does. If this proves unsafe for garbage collection, the stack region for such a call may have to + have suitable frames containing pointers to the lower part of the stack (or vice-versa) placed in it to repair + this deficiency. Also, the way garbage collection safety of Icon values in C++ variables is ensured is to use the + constructor to implicitly link them onto the far end of the main co-expression's safe list, and unlink them from + there using the destructor. This is almost certainly safe from the usual call and return mechanism in iconx for + protecting local variables, but needs testing and verification.<BR> + <BR> + 2009/1/20 fixed a bug where a call of any C++ external function that in turn calls Icon and afterIcon returns calls + Icon::runerr would not correctly report the name and arguments of said function in the resulting traceback. Upped + the version number to 0.91alpha.<BR> + <BR> + 2009/1/20 loadfuncpp now searches for a shared object on the path defined by the environment variable FPATH with + the icon/bin directory appended if you specify no path. FPATH undefined leads loadfuncpp to search the current + directory followed by the icon/bin directory.<BR> + <BR> + 2009/1/12 <FONT COLOR="#FF9900">loadfuncpp has been completely overhauled</FONT>, and the old version is now obsolete. + Many small functions have been added to eliminate ambiguities in programs that use loadfuncpp, and the central + class has been renamed and a class eliminated. Small pieces of missing functionality have been added. The documentation + has been modified accordingly. It is now close to it's final form, and in need of some serious beta testing, and + I have someone who has agreed to do that. Once this is done, loadfuncpp will be made available as a pack with the + Icon 9.5 source distribution. + </BLOCKQUOTE> + </BLOCKQUOTE> + </TD> + </TR> +</TABLE> + +</CENTER> + +</BODY> + +</HTML> |
