FIXED:findCell() in DAT causes memory leak in TouchDesigner 2023.12000

Bugs

I’ve encountered a memory leak issue in TouchDesigner version 2023.12000 related to the DAT method findCell().

When I repeatedly call findCell() on a DAT in a loop or from a script, memory usage increases continuously and is never released, leading to a memory leak.
In contrast, using findCells() under the same conditions does not cause any memory increase.

findCell.toe (3.7 KB)

Reproducible Example:

# This leaks memory
for _ in range(100000):
    dat.findCell('someValue', cols=['colname'])

# This does not leak
for _ in range(100000):
    dat.findCells('someValue', cols=['colname'])

Environment:

  • TouchDesigner version: 2023.12000
  • OS: Windows10, Mac

Let me know if this is a known issue or if I can provide further details.

Thanks!

Thanks for the concise test case.
We are investigating.

EDIT:
This will now be fixed in builds 2023.12300 and later.

Cheers
