Huge typeset -L/-R adjustment length values were still causing crashses on sytems with not enough memory. They should error out gracefully instead of crashing. This commit adds out of memory checks to all malloc/calloc/realloc calls that didn't have them (which is all but two or three). The stkalloc/stakalloc calls don't need the checks; it has automatic checking, which is done by passing a pointer to the outofspace() function to the stakinstall() call in init.c. src/lib/libast/include/error.h: - Change the ERROR_PANIC exit status value from ERROR_LEVEL (255) to 77, which is what it is supposed to be according to the libast error.3 manual page. Exit statuses > 128 for anything else than signals are not POSIX compliant and may cause misbehaviour. src/cmd/ksh93/include/defs.h, src/cmd/ksh93/sh/init.c: - To facilitate consistency, add a simple extern sh_outofmemory() function that throws an ERROR_PANIC "out of memory". src/cmd/ksh93/include/shell.h, src/cmd/ksh93/data/builtins.c: - Remove now-redundant e_nospace[] extern message; it is now only used in one place so it might as well be a string literal in sh_outofmemory(). All other changed files: - Verify the result of all malloc/calloc/realloc calls and call sh_outofmemory() if they fail. |
