Description

Running the tests on meas_base in my Python 3 stack, I sometimes get a failure in testSdssCentroid.testMonteCarlo:

$ python tests/testSdssCentroid.py

testEdge (__main__.SdssCentroidTestCase) ... measurement: Measuring 1 sources (1 parents, 0 children)

ok

testMonteCarlo (__main__.SdssCentroidTestCase)

Test that we get exactly the right answer on an ideal sim with no noise, and that ... /Users/timj/work/lsstsw3/stack/DarwinX86/utils/12.0-9-gf85c792/python/lsst/utils/tests.py:667: DeprecationWarning: assertClose is deprecated; please use TestCase.assertFloatsAlmostEqual

Jim Bosch seems to think it's triggered by an instability in the random seed.

The segv happens at:

28  _tableLib.so                  	0x000000010799eb1d SWIG_Python_GetSwigThis(_object*) + 221 (tableLib_wrap.cc:2316)

29  _tableLib.so                  	0x000000010799e782 SWIG_Python_ConvertPtrAndOwn(_object*, void**, swig_type_info*, int, int*) + 98 (tableLib_wrap.cc:2366)

30  _tableLib.so                  	0x0000000107929598 _wrap__SourceCatalogBase_getTable(_object*, _object*) + 88 (tableLib_wrap.cc:120031)

The lines reported in the recursion trap are relating to attributes in tableLib.py

  11029     def __getattribute__(self, name):

  11030     # Catalog forwards unknown method calls to its table and column view

  11031     # for convenience.  (Feature requested by RHL; complaints about magic

  11032     # should be directed to him.)

  11033     # We have to use __getattribute__ because SWIG overrides __getattr__.

  11034         try:

  11035             return object.__getattribute__(self, name)

  11036         except AttributeError:

  11037     # self._columns is created the when self.columns is accessed -

  11038     # looking for it in self.columns below would trigger infinite

  11039     # recursion.

  11040             if name == "_columns":

  11041                 raise

  11042         try:

  11043             return getattr(self.table, name)

  11044         except AttributeError:

  11045             return getattr(self.columns, name)

  11046     table = property(getTable)

  11047     schema = property(getSchema)

Trapping for "this" in addition to "_columns" on line 11040 fixes the problem but there is concern that we do not really understand the condition that is leading to this.

Setting the seed with numpy.random.seed(500) does not affect the behavior. Sometimes it works. I'm hoping this is a bad afw build on my system.

This is not a bad build on your system. I am seemingly able to reproduce the same (or very similar) behavior in meas_algorithms (on the py 3 porting branch tickets/~~DM-7289~~) by running testMeasureApCorr.py . Note to run this you will probably need to set up the py 3 ticket branch of esutils as well (~~DM-7294~~).

The feeling is that SWIG is requesting the "this" attribute and expecting an AttributeError to let it know that an internal SWIG object has not yet been stored.

For the record: I see the if name == "_columns": raise sequence in the Python 2 version of tableLib.py, and if I put in a test for name == "this" I get lots of hits. So I think the bug exists in Python 2 as well.

There is a solution for this problem in master now. This seems to be related to swig, and should not be necessary once the pybind11 merge is done. Verification that no further bug exists will happen during the pybind11 verification. Jim Bosch
