Wed May 1 09:06:23 PDT 2002 olaf * Modifyied both nhc98 runtime system and hat library to catch runtime errors. The nhc98 runtime system now has the global variable void (*haskellErrorHandler)(char *errorMsg) = NULL; If it is not null, it will be called for runtime errors that are not handled by Haskell's "error"; i.e. currently "out of heap" and "black hole". The hat_open function sets haskellErrorHandler to an appropriate function that writes the error message to the trace and closes it. (only if compiled for nhc98) Also added handling of arithmetic error signals to the hat library.

Wed May 1 06:51:58 PDT 2002 malcolm * In the basic Hat C routines: * Use the ErrorMessage pointer in the .hat header to distinguish between _|_ and ^C. * Open the .hat.bridge file at the same time as the .hat file, and add error checking on the header, filesize, etc. * Fix a couple of bugs where routines forgot to check for a FileOffset in the range 0-4 (Root..Lambda) M ./src/hattools/artutils.c -12 +54

patch applied (hat): Use unsafePerform in a safer way, so that marshalling of strings and arrays also works with nhc98.

Tue Apr 30 09:46:51 PDT 2002 olaf * Use unsafePerform in a safer way, so that marshalling of strings and arrays also works with nhc98. Also modified constUse to ensure that black hole errors are correctly located in the trace. However, the constUse is already evaluated when the black hole error occurs. So using a stack for entering/result would probably lead to wrong error position. M ./src/hatlib/Hat.hs -27 +37
