Description

The actual GammaLib code has many exceptions, basically one per exception. This makes things difficult to manage. As the exceptions all have their associated error message, the exceptions can be reduced to some generic ones.

Remove any exceptions for the CTA exceptions class that are redundant with GammaLib GExceptions. CTA exceptions should only contain exceptions that are proper to the CTA classes and methods.

Recurrence

No recurrence.

All specific exceptions were removed and replaced by generic exceptions. A number of help functions were implemented to reduce code duplications. The unit test scripts were also adapted to test now the generic instead of the specific exceptions.

#16 Updated by Knödlseder Jürgen over 3 years ago

Testing the code integration, on Debian and and Free BSD the following unit test error occurs:

*** ERROR in GPythonTestSuite::test: <type 'exceptions.RuntimeError'> *** ERROR in GFits::saveto(GFilename&, bool&): Invalid value. Attempted to overwrite FITS file "test_python_skymap_hpx_v2.fits". Please set clobber flag to true.

Not sure what makes these systems different. Debian has Python 2.6, Free BSD has Python 2.7. Debian has gcc 4.4.5, Free BSD has gcc 4.2.1.

The relevant Python code before the change was 

        # Save HEALPix skymap twice. The second saving should fail.
        try:
            pixels.save(file2, True)
            pixels.save(file2)
        except RuntimeError:
            pass
        else:
            raise RuntimeError('*** TEST ERROR: FITS file overwritten!')
and after the change it is
        # Save HEALPix skymap twice. The second saving should fail.
        try:
            pixels.save(file2, True)
            pixels.save(file2)
        except ValueError:
            pass
        else:
            raise RuntimeError('*** TEST ERROR: FITS file overwritten!')
This explains why this error did not occur before.

#17 Updated by Knödlseder Jürgen over 3 years ago

I’m wondering whether this has to do this the RTLD_GLOBAL flag mentioned here: https://stackoverflow.com/questions/7121631/uncatchable-c-exceptions-shared-libs-arm-linux-gnueabi-g.

#19 Updated by Knödlseder Jürgen over 3 years ago

Debugging the code on Debian, it appears that in the block

    try {
      ((GSkyMap const *)arg1)->save((GFilename const &)*arg2);
    }
    catch (const GException::out_of_range& e) {
      SWIG_exception(SWIG_IndexError, e.what());
    }
    catch (const GException::invalid_value& e) {
      SWIG_exception(SWIG_ValueError, e.what());
    }
    catch (const GException::invalid_argument& e) {
      SWIG_exception(SWIG_ValueError, e.what());
    }
    catch (const GException::invalid_return_value& e) {
      SWIG_exception(SWIG_ValueError, e.what());
    }
    catch (const GException::fits_error& e) {
      SWIG_exception(SWIG_IOError, e.what());
    }
    catch (const GException::file_error& e) {
      SWIG_exception(SWIG_IOError, e.what());
    }
    catch (const GException::runtime_error& e) {
      SWIG_exception(SWIG_RuntimeError, e.what());
    }
    catch (const GException& e) {
      SWIG_exception(SWIG_RuntimeError, e.what());
    }
    catch (const std::exception& e) {
      SWIG_exception(SWIG_RuntimeError, e.what());
    }
    catch (...) {
      SWIG_exception(SWIG_RuntimeError, "unknown exception");
    }
the exception that is catch is std::exception&, hence the GException class instances are ignored.

#20 Updated by Knödlseder Jürgen over 3 years ago

The page https://stackoverflow.com/questions/6324299/problem-throwing-and-catching-custom-exceptions-in-c hints that the exception may not be exported properly.

One possibility is that the gcc compilers are too old: https://github.com/aalexand/sharedlib_typeinfo.

And here some code that manipulates dynamic load flags: http://doxygen.lsst.codes/stack/doxygen/x_11_0/lsstimport_8py_source.html. I tried setting the flag to 258 before loading the module but this did not change the behaviour.

#21 Updated by Knödlseder Jürgen over 3 years ago

Inspecting the symbols of the Python module it seems that the GammaLib exception methods are all there:

Note however that the vtable does not exist for GException::invalid_value. For comparison, here is the result on CentOS 6. Things look pretty much identical there:

#22 Updated by Knödlseder Jürgen over 3 years ago

Adding the code

    catch (const std::exception& e) {
printf("std::exception\n");
      const GException::invalid_argument* ptr1 = dynamic_cast<const GException::invalid_argument*>(&e); 
      const GException::invalid_value*    ptr2 = dynamic_cast<const GException::invalid_value*>(&e); 
printf("%p, %p\n", ptr1, ptr2);
results in
std::exception
(nil), (nil)
which means that the issue is that virtual tables are not exported as they should.

Checking the symbols in GammaLib on Debian also looks reasonable (and similar to CentOS 6):

#24 Updated by Knödlseder Jürgen over 3 years ago

I added an equivalent C++ test

    // Test saving
    test_try("Test saving");
    try {
        GSkyMap map("GAL", 1, "RING", 1);
        map.save("test_cpp_skymap_hpx_v2.fits", true);
        map.save("test_cpp_skymap_hpx_v2.fits");
        test_try_failure();
    }
    catch (GException::invalid_value &e) {
        test_try_success();
    }
    catch (std::exception &e) {
        test_try_failure(e);
    }
and this test succeded
<testcase classname="GSky" name="Test Healpix GSkyMap constructors: Test saving" time="0.000" />
Hence the issue seems to be related to the Python interface.

#25 Updated by Knödlseder Jürgen over 3 years ago

I found a solution!

By adding

import sys

# Get original flags
originalDLFlags = sys.getdlopenflags()

# Set RTLD_GLOBAL | RTLD_NOW
sys.setdlopenflags(258)

# Import modules
from gammalib.app import *
...

# Reset original flags
sys.setdlopenflags(originalDLFlags)
to pyext/__init__.py the issue was solved.
