Node not Found error with current release - posted for KSTAR

[joshStillerman]

KSTAR has run into a problem with a set of arithmetic nodes that evaluate fine on 6.1-84 but not on the current versions. The nodes decompile to things like:

Build_With_Units((_gain = \MAGNETIC::RC03:GAIN, _conv = \MAGNETIC::RC03:CONV, _tau = \MAGNETIC::RC03:TAU, _y1fit = MEAN(DATA(\MAGNETIC::RC03:FOO)[\MAGNETIC::RC03:FIT_P1 : \MAGNETIC::RC03:FIT_P1 + \MAGNETIC::RC03:FREQ * .1 : *], 0), _y2fit = MEAN(DATA(\MAGNETIC::RC03:FOO)[\MAGNETIC::RC03:FIT_P2 : \MAGNETIC::RC03:FIT_P2 + \MAGNETIC::RC03:FREQ * .1 : *], 0), _x1fit = \MAGNETIC::RC03:FIT_P1 + \MAGNETIC::RC03:FREQ * .05, _x2fit = \MAGNETIC::RC03:FIT_P2 + \MAGNETIC::RC03:FREQ * .05, _fitdata = (_y2fit - _y1fit) / (_x2fit - _x1fit) * DATA([0 : SIZE(\MAGNETIC::RC03:FOO) - 1 : *]) + _y1fit - (_y2fit - _y1fit) / (_x2fit - _x1fit) * _x1fit, (\MAGNETIC::RC03:FOO - _fitdata) * (_conv * _gain) * 1000 * _tau * 1 * 1), "A")

and when evaluated come up with MDSplus.mdsExceptions.TreeNNF: %TREE-W-NNF, Node Not Found

>>> data = n.data()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/mdsplus/python/MDSplus/tree.py", line 1538, in data
    return self.record.data(*altvalue)
  File "/usr/local/mdsplus/python/MDSplus/mdsdata.py", line 622, in data
    data = _cmp.DATA(self).evaluate()
  File "/usr/local/mdsplus/python/MDSplus/compound.py", line 391, in evaluate
    _exc.checkStatus(_TdiShr._TdiIntrinsic(
  File "/usr/local/mdsplus/python/MDSplus/mdsExceptions.py", line 94, in checkStatus
    raise exception
MDSplus.mdsExceptions.TreeNNF: %TREE-W-NNF, Node Not Found

I will verify that all the terms are there and evaluable as a first step.

I added an idea to discord https://discord.gg/4gt6RbhHDm #developers suggesting we add a logging capability to treeshr so we can trace all the nodes retrieved by getRecord

[joshStillerman]

With the current alpha the node t._MP1P01Z is evaluable.

I will try the same tests with the current stable.

the nodes referred to in the expression are:

t._MP1P01Z.FIT_P2.data()
t._MP1P01Z.FOO.data()
t._MP1P01Z.FREQ.data()
t._MP1P01Z.GAIN2.data()
t._MP1P01Z.NA.data()
t._MP1P01Z.POLARITY.data()
t._MP1P01Z.TAU.data()

Note: there are serveral references to t._MP1P01Z.FOO which is pretty expensive in terms of time, making the whole evaluation pretty slow

Please verify that you are running: 7.131.6 by typing

jas@mfews-jas:~/kstar/KSTAR_27425$ mdstcl
TCLshow version


MDSplus version: 7.131.6

Note that my output is slightly different since i built this version by hand.

On my system it seems to work:
