Description

Working further on my MAPM bindings I discovered that throwing exceptions while using result caused ARC to not create a destroy call for result. My smallest repro currently:

import system/ansi_c

type
  MyError = object of CatchableError
  MyObj = object
    internal: pointer

proc `=destroy`(x: MyObj) =
  if x.internal.isNil: return
  x.internal.c_free

proc `=copy`(x: var MyObj, y: MyObj) =
  if x.internal != y.internal:
    x.internal.c_free
    x.internal = y.internal

proc initMyObj(x: string): MyObj =
  result = MyObj(internal: c_malloc(126))
  if x.len < 128:
    result.internal.copyMem(x[0].addr, x.len)
  else:
    raise newException(MyError, "This is an error")

import strutils

try:
  echo initMyObj("Hello world")
  echo initMyObj("Hello world".repeat(128))
except MyError as e:
  echo "Got an error!"
  echo e.msg

Nim Version

v2.0.0 and devel

Current Output

From --expandArc:initMyObj:

result = MyObj(internal: c_malloc(126'u))
if len(x) < 128:
  copyMem(result.internal, addr(x[0]), chckRange(len(x), 0, 9223372036854775807))
else:
  raise
    (ref MyError)(msg: "This is an error", parent: nil)

Confirmed with valgrind --leak-check=full that it does in fact leak:

==1808387== 126 bytes in 1 blocks are definitely lost in loss record 1 of 2
==1808387==    at 0x4841848: malloc (vg_replace_malloc.c:431)
==1808387==    by 0x10E773: initMyObj__test_u10 (test.nim:18)
==1808387==    by 0x10E9DD: NimMainModule (test.nim:28)
==1808387==    by 0x109171: NimMainInner (typedthreads.nim:269)
==1808387==    by 0x109171: NimMain (typedthreads.nim:280)
==1808387==    by 0x109171: main (typedthreads.nim:288)

Expected Output

Based on the output of replacing result with a variable and returning it at the end of the function:

var res
try:
  res = MyObj(internal: c_malloc(126'u))
  if len(x) < 128:
    copyMem(res.internal, addr(x[0]), chckRange(len(x), 0, 9223372036854775807))
  else:
    raise
      (ref MyError)(msg: "This is an error", parent: nil)
  return
    result = res
    `=wasMoved`(res)
finally:
  `=destroy`(res)

Removing the line which causes the exception makes Valgrind run clean, same for using a variable to store the result and explicitly returning it.

No need for anything special, result just doesn't receive a call to destroy here. This will eat up memory pretty quick

proc leakMemory(): seq[char] =
  result = newSeq[char](128)
  raise newException(CatchableError, "This is an error")

while true:
  try:
    discard leakMemory()
  except CatchableError:
    echo GC_getStatistics()

This also leaks, so not exclusive to result (--exceptions:setjmp doesn't leak for this one, but I got no clue how to make use of that handler)

proc leakMemory(): seq[char] =
  var res = newSeq[char](128)
  try:
    raise newException(CatchableError, "This is an error")
  finally:
    return res

while true:
  try:
    discard leakMemory()
  except CatchableError:
    echo GC_getStatistics()

Another example: it leaks with ORC

import std/json

let startMemory = getOccupiedMem()
for i in 0 .. 10000:
  try:
    discard parseJson"""{ invalid"""
  except:
    discard
doAssert(abs(getOccupiedMem() - startMemory) < 4 * 1024 * 1024)

Just checked to see if this had been fixed in 2.0.4 and it is still present.
