Heap space exhausted - solution and why

[Draconis (Daniel Stelzer)]

Coming back to this now, I think the issue is in the data structure Dialog uses to hold the word-to-object mappings, known as the “wordmap”. This data structure is entirely undocumented, but this is the code that generates it, in backend_z.c:

static int generate_wordmap(struct wordmap *map, int *nptr) {
	int n, j, k, id, len;
	uint8_t data[1 + 2 * MAXWORDMAP];
	uint16_t words[map->nmap * 2];

	n = map->nmap;
	if(map->map[n - 1].key == 0xffff) n--;
	assert(n > 0);
	*nptr = n;
	for(j = 0; j < n; j++) {
		words[2 * j + 0] = map->map[j].key;
		if(map->map[j].count > MAXWORDMAP) {
			words[2 * j + 1] = 0;
		} else if(map->map[j].count == 1) {
			words[2 * j + 1] = 1 + map->map[j].onumtable[0];
		} else {
			len = 1;
			for(k = 0; k < map->map[j].count; k++) {
				id = 1 + map->map[j].onumtable[k];
				if(id < 0xe0) {
					data[len++] = id;
				} else {
					assert(id <= 0x1fff);
					data[len++] = 0xe0 | (id >> 8);
					data[len++] = id & 0xff;
				}
			}
			data[0] = len - 1;
			for(k = 0; k < ndatatable; k++) {
				if(datatable[k].length == len
				&& !memcmp(datatable[k].data, data, len)) {
					break;
				}
			}
			if(k == ndatatable) {
				datatable = realloc(datatable, ++ndatatable * sizeof(*datatable));
				datatable[k].label = make_global_label();
				datatable[k].length = len;
				datatable[k].data = malloc(len);
				memcpy(datatable[k].data, data, len);
			}
			words[2 * j + 1] = 0x8000 | datatable[k].label;
		}
	}
	for(j = 0; j < nwordtable; j++) {
		if(wordtable[j].length == n * 2
		&& !memcmp(wordtable[j].words, words, n * 2 * sizeof(uint16_t))) {
			break;
		}
	}
	if(j == nwordtable) {
		wordtable = realloc(wordtable, ++nwordtable * sizeof(*wordtable));
		wordtable[j].label = make_global_label();
		wordtable[j].length = n * 2;
		wordtable[j].words = malloc(n * 2 * sizeof(uint16_t));
		memcpy(wordtable[j].words, words, n * 2 * sizeof(uint16_t));
	}
	return j;
}

And this is how it’s called, when it encounters the instruction CHECK_WORDMAP in the intermediate representation of the code:

assert(ci->oper[0].tag == OPER_NUM);
assert(ci->oper[2].tag == OPER_PRED);
assert(ci->oper[0].value < prg->predicates[ci->oper[2].value]->pred->nwordmap);
map = &prg->predicates[ci->oper[2].value]->pred->wordmaps[ci->oper[0].value];
id = generate_wordmap(map, &n);
zi = append_instr(r, Z_CALLVS);
zi->oper[0] = ROUTINE(R_WORDMAP);
zi->oper[1] = REF(wordtable[id].label);
zi->oper[2] = SMALL_OR_LARGE(n);
zi->oper[3] = VALUE(REG_IDX);
zi->store = REG_TEMP;
zi = append_instr(r, Z_JNZ);
zi->oper[0] = VALUE(REG_TEMP);
if(ci->oper[1].tag == OPER_FAIL) {
	zi->branch = RFALSE;
} else {
	assert(ci->oper[1].tag == OPER_RLAB);
	if(pred->routines[ci->oper[1].value].reftrack == r_id) {
		zi->branch = llabel[ci->oper[1].value];
		if(!encountered[ci->oper[1].value]) {
			rstack[rsp++] = ci->oper[1].value;
			encountered[ci->oper[1].value] = 1;
		}
	} else {
		ll = r->next_label++;
		zi->op ^= OP_NOT;
		zi->branch = ll;
		zi = append_instr(r, Z_RET);
		zi->oper[0] = ROUTINE(rlabel[ci->oper[1].value]);
		zi = append_instr(r, OP_LABEL(ll));
	}
}
break;

I’m utterly baffled by what’s going on here, but maybe someone with better C or Z-machine skills will recognize what’s happening. If only there were comments!

Blimey! That’s some seriously inscrutable code.

[andrewj]

This seems to be the implementation for (determine object $) .. (from words) .. (matching all of $) built-in predicate, described in the I/O chapter.

[jwalrus (Adam Biltcliffe)]

My hypothesis was that the error arose when the number of steps of binary search needed to find a word in some data structure exceeded a certain amount. That would explain why the error appears not at all below a certain number of words, unpredictably for a while beyond that (because unless the number of words is an exact power of two, some words will require one more step than others), and consistently once you reach some further point.

The veneer routine R_WORDMAP (in runtime_z.c) does indeed contain logic to do a binary search on the wordmap if it contains at least 16 entries. But it’s a pretty small loop and certainly doesn’t appear to contain anything that could lead to a heap allocation, so I don’t think that can be it at all:

R_WORDMAP

R_WORDMAP,
		5,
			// 0 (param): raw pointer to wordmap, then entry address, then payload pos
			// 1 (param): number of entries in wordmap, then payload pointer
			// 2 (param): deref'd key, then payload size
			// 3: pivot index, payload byte
			// 4: pivot element, object number
		(struct zinstr []) {
			{Z_JL, {VALUE(REG_LOCAL+1), SMALL(16)}, 0, 3},

			// If the table is very large, use binary search.
			{OP_LABEL(5)},
			{Z_AND, {VALUE(REG_LOCAL+1), LARGE(0xfffe)}, REG_LOCAL+3}, // divide length by two, then multiply by two
			{Z_LOADW, {VALUE(REG_LOCAL+0), VALUE(REG_LOCAL+3)}, REG_LOCAL+4},
			{Z_JL, {VALUE(REG_LOCAL+2), VALUE(REG_LOCAL+4)}, 0, 4},

			{Z_ADD, {VALUE(REG_LOCAL+0), VALUE(REG_LOCAL+3)}, REG_LOCAL+0},
			{Z_ADD, {VALUE(REG_LOCAL+0), VALUE(REG_LOCAL+3)}, REG_LOCAL+0},
			{Z_INC, {SMALL(REG_LOCAL+1)}}, // round up in the shift

			{OP_LABEL(4)},
			{Z_LSHIFT, {VALUE(REG_LOCAL+1), VALUE(REG_FFFF)}, REG_LOCAL+1},
			{Z_JGE, {VALUE(REG_LOCAL+1), SMALL(16)}, 0, 5},

			{OP_LABEL(3)},

			// For an unknown word, perhaps a verb, return true without pushing anything.
			{Z_SCANTABLE_N, {VALUE(REG_LOCAL+2), VALUE(REG_LOCAL+0), VALUE(REG_LOCAL+1), SMALL(0x84)}, REG_LOCAL+0, RTRUE},

			{Z_LOADW, {VALUE(REG_LOCAL+0), SMALL(1)}, REG_LOCAL+1},
			// For a common word, perhaps 'of', return false without pushing anything.
			{Z_JZ, {VALUE(REG_LOCAL+1)}, 0, RFALSE},

			// For a known word, push a number of objects and return true.
			{Z_JG, {VALUE(REG_LOCAL+1), REF(G_OBJECT_ID_END)}, 0, 2},

			// Special treatment for single-element lists: The
			// object table is located before the wordmaps, so
			// object numbers can't collide with addresses.
			{Z_CALL2N, {ROUTINE(R_AUX_PUSH1), VALUE(REG_LOCAL+1)}},
			{Z_RTRUE},

			{OP_LABEL(2)},
			{Z_LOADB, {VALUE(REG_LOCAL+1), SMALL(0)}, REG_LOCAL+2},
			{Z_STORE, {SMALL(REG_LOCAL+0), SMALL(1)}},

			{OP_LABEL(1)},
			{Z_LOADB, {VALUE(REG_LOCAL+1), VALUE(REG_LOCAL+0)}, REG_LOCAL+4},
			{Z_JL, {VALUE(REG_LOCAL+4), SMALL(0xe0)}, 0, 6},

			{Z_INC, {SMALL(REG_LOCAL+0)}},
			{Z_LOADB, {VALUE(REG_LOCAL+1), VALUE(REG_LOCAL+0)}, REG_LOCAL+3},

			{Z_AND, {VALUE(REG_LOCAL+4), SMALL(0x1f)}, REG_LOCAL+4},
			{Z_LSHIFT, {VALUE(REG_LOCAL+4), SMALL(8)}, REG_LOCAL+4},
			{Z_OR, {VALUE(REG_LOCAL+4), VALUE(REG_LOCAL+3)}, REG_LOCAL+4},

			{OP_LABEL(6)},
			{Z_CALL2N, {ROUTINE(R_AUX_PUSH1), VALUE(REG_LOCAL+4)}},
			{Z_INC_JLE, {SMALL(REG_LOCAL+0), VALUE(REG_LOCAL+2)}, 0, 1},

			{Z_RTRUE},
			{Z_END},
		}

Notably, backend_z.c does contain a specific limit on how many dictionary words there can be:

	if(prg->ndictword >= 0x1e00) {
		report(LVL_ERR, 0, "Too many dictionary words.");
		exit(1);
	}

Which suggests that this code is supposed to be robust enough to work up to 7680 words, and this crash is not expected behavior.

[Draconis (Daniel Stelzer)]

From the Å-machine documentation, this is how the I_CHECK_WORDMAP instruction is supposed to work:

local variable objs[] = find_in_wordmap(wordmaps[arg1], IDX)
if(objs == null) {
	// The word was not in the table, and should not
	// match anything.
	// Nothing was pushed, so jump to enforce that.
	INST = arg2
} else if(objs.length == 0) {
	// The word is a wildcard, so don't jump.
} else {
	// The word matches a limited number of objects.
	// Push them and jump to enforce that.
	if(AUX + objs.length > TRL) runtime_error(2)
	for(local variable i = 0; i < objs.length; i++) {
		aux[AUX++] = objs[i]
	}
	INST = arg2
}

IDX is a general-purpose register, INST is the program counter.

Each wordmap is an array of entries, where each entry consists of a dictionary word and a payload; the payload is either null, a single object ID, or a pointer to a null-terminated array of object IDs in memory.

I think the next thing I want to do is add various debugging output to the wordmap generator in the compiler, then take some code that doesn’t trigger the bug, and some code that does trigger the bug, and see what the difference in the data structures is.

Do we have a good test case that’s right at the edge of reliably triggering this behavior?

@bkirwi had a post above…

Heap space exhausted - solution and why

I’m running into “(Technical trouble: Heap space exhausted. Attempting to recover with UNDO.)” errors in my current work in progress, and I’m struggling to work out what I’ve done wrong. The errors occur if you use custom verbs or refer to objects that are out of scope. The errors don’t occur if I’m using the interactive debugger, only if I compile to z5 or z8 and run the file in WinFrotz or Gargoyle. Looking at this page in the manual, I added (display memory statistics) to the (error $Code …

…that might be useful.

(sorry for the formatting, i don’t know how to cleanly insert a link to another post).

[nephar (Timur Ozturk)]

Based on our experiences so far, taking any PD/open source code with lots of objects and adding per object variables to an object is a promising way to trigger those parsing fails in z-machine.

[Draconis (Daniel Stelzer)]

Wait, hold the phone! The original explode.dg crashed on the word “jail”, right?

Let me try the modified explode(1).dg, which crashes on “wing”.

[Draconis (Daniel Stelzer)]

Here’s the output of explode(1).dg, which crashes on “receipt”.

Well, this helped me find an error in my instrumentation: the first entry in each datatable shouldn’t be read as an object ID, but as the length of the table. So disregard that one.

But the datatables are assigned alphabetically, and it looks like something bad is happening at table 137. We’re getting close, I think!

[Draconis (Daniel Stelzer)]

Aha. Wait. You said this only crashed if the heap size was at its maximum, right?

I think I’ve found it. Look at this version.

This crashes on “pupil” but not on “provoke”. That means the issue is between tables 133 and 134—that is, the ones above 0x8000. And 0x8000 is the lowest address that is treated as negative when doing signed math.

Something in the Z-machine code is doing signed math on the datatable address, or the addresses around it, and going into an infinite loop if the result is negative.

[Draconis (Daniel Stelzer)]

Yep, here it is. The logic of R_WORDMAP is:

• If the number of entries ≥ 16, divide in half until it’s less than 16. (Not relevant here.)
• Do a linear search through the table, looking at the first two bytes of each four-byte block. If none of them match, return true.
• Load the two-byte word immediately after the matching address.
• If it’s zero, return false.
• If it’s ≤ the maximum object ID, push it and return true.
• Go to that address and unpack the list, pushing each value in turn. Then return true. (Not relevant here.)

And a datatable address that’s greater than 0x8000 will always be lower than the maximum object ID, because this is a signed comparison! This also needs to check if the address is less than zero.

[Draconis (Daniel Stelzer)]

Yep, that did it! I think we can consider this bug officially fixed!

[improvmonster]

does this mean i can use per-object variables again without holding my breath?

[Draconis (Daniel Stelzer)]

I think so, yes! Those are stored in memory before the wordtables and datatables, and now you no longer need to worry about them pushing the wordtables over the $8000 limit.

Per-object variables are still horribly unoptimized at present compared to Inform, but this should give you a lot more breathing room.

And if they do still become a problem, the biggest issue with per-object variables is that every object in the game gets them, you can’t restrict them to specific objects or kinds of objects. But you can use access predicates to get around that too. Suppose you’re writing Adventure, and need to keep track of the last time you visited a room, and the previous location of each dwarf. You can store those in the same variable, since dwarves and rooms have no overlap!

@($Room was last visited $Time)
    (generic object variable $Room $Time)
@($Dwarf was last in $Location)
    (generic object variable $Dwarf $Location)

Thinking on it more, Dialog isn’t really that inefficient about per-object variables. Inform 6 has several properties that apply to all objects that Dialog doesn’t, like the dictionary words, short name, and description. So why is it such a problem to use per-object variables in Dialog?

Well, with this bug fixed, it seems like it isn’t! I added twenty extra per-object variables to Miss Gosling and it caused no problems whatsoever on a full-game runthrough. I think we can officially stop telling people that they need to avoid those!
