@mr-c I don't think the Travis bot quite triggered on this PR |

There was a problem hiding this comment.
We don't use the word "hash" in front of users as it is an implementation detail. Yes, the Python API is going to get a lot of methods renamed :-)
Use "counting table" here instead.
…tent with other negative tests

A number of
table.get("wrong_length_string")functions when called from Python would lead to an unhandled C++ exception, and a subsequent termination (Issue #174).Note: These reported paths to trigger the core dump included
table = khmer.new_hashbits(...),table = khmer.new_hashtable(...), andtable = khmer.new_counting_hash(...)Test Driven Development techniques were adopted in resolving this issue. Failing unit tests were written first based upon the user report, and then proposed patches committed until all the tests passed.
This methodology assisted in finding a second location in
khmer\_khmermodule.ccthat required the same fix. This was not immediately apparent upon first review of the C++ code.Testing the reproduction steps with gdb debugger and valgrind confirm the core dump is mitigated.
