critbits.nim `rawGet` causes `FieldDefect: field 'key' is not accessible for type 'NodeObj' using 'isLeaf = 255'` when run multiple times with `-mm:orc`

Open PhilippMDoerner opened this issue 1 year ago • 0 comments

What happened?

I have a larger web application I am writing with the prologue framework, which makes use of hasKey from critbits.nim which in turn makes use of rawGet. Normally everything works perfectly fine, all HTTP endpoints are perfect.

However, when making multiple requests in short succession, under some circumstances (namely when triggering the /sessionaudio and /timestamp routes together repeatedly) it causes the error:

Exception message: field 'key' is not accessible for type 'NodeObj' using 'isLeaf = 255'

I have no understanding of what causes this bug, as it does a) not appear consistently and b) does not occur in code that I have any understanding of.

I can say the following:

  1. This error does not occur when using refc instead of orc
  2. This error does not occur when using asynchttpserver

Thus the error appears to be specific to orc and httpx (?).

Possible Solution

I have troubleshot the passages together with ringabout. We narrowed the issue down to the proc rawGet. We further found a solution, as apparently all it takes is modifying rawGet a little bit to look like this:

# Before - Aka the broken version
proc rawGet[T](c: CritBitTree[T], key: string): Node[T]=
  var it = c.root
  while it != nil:
    if not it.isLeaf:
      let ch = if it.byte < key.len: key[it.byte] else: '\0'
      let dir = (1 + (ch.ord or it.otherBits.ord)) shr 8
      it = it.child[dir]
    else:
      return if it.key == key: it else: nil

# After - Aka the functional version, changes start after the line `it = it.child[dir]`
proc rawGet[T](c: CritBitTree[T], key: string): Node[T]=
  var it = c.root
  while it != nil:
    if not it.isLeaf:
      let ch = if it.byte < key.len: key[it.byte] else: '\0'
      let dir = (1 + (ch.ord or it.otherBits.ord)) shr 8
      it = it.child[dir]
    else:
      let itKey = it.key
      if itKey == key:
        return it
      else:
        return nil

As I have no understanding on why this actually fixes things, I'll quote ringabout here:

I guess ORC doesn't like complex expressions. return if it.key == key: it else: nil I guess the root cause is that it gets moved wrongly in the while loop and this if statement.

Additional Information

We essentially already have the solution (though I still don't know why that's a bug/problem) thanks to ringabout! I'll write up the PR to apply their change.
