next-property

by Olivier Danet

I may have found a bug in OpenBIOS. An OS uses the "nextprop" iterator to scan device properties, and eventually asks about nonexistant properties. "const char *obp_nextprop(int node, const char *name)" (arch/sparc32/romvec.c) calls the "next-property" forth code, then pops the result. According to the standard, next-property should return 0 if the property selected is the last _OR_ if the property does not exist. The current code in forth/admin/devices.fs returns nothing when the property does not exit. For example (SPARC 32) : cd screen " name" ?active-package next-property drop cr type --> returns "device_type" " interrupts" ?active-package next-property --> returns 0, this is the last property. " bozo" ?active-package next-property --> returns nothing. Which, imho, is wrong. Here is a patch, I am not quite sure about it (debuting Forth) but it helps the target OS : Index: forth/device/property.fs =================================================================== --- forth/device/property.fs (révision 1246) +++ forth/device/property.fs (copie de travail) @@ -70,7 +70,7 @@ 2drop r> >dn.properties @ else r> find-property dup if @ then - ?dup if >prop.next @ then + dup if >prop.next @ then then ?dup if =================================================================== The standard asks for a pointer to a zero lenght string instead of zero, the C code obp_nextprop() expects a zero. I don't know if it makes a difference. Olivier (Btw, the OS is NetBSD :-)

Does NetBSD 6 do something different that the others don't? ATB, Mark.
