Hi Phil,
I found a new bug in SIP (it used to work with a SIP from September 2007).
If you declare a class with a single constructor, you write %MethodCode
for that constructor, and you make it raise an exception (PyErr_Format)
and set sipIsErr=1, the exception is not propagated to Python: it gets
"swallowed" and changed into an AttributeError which says "... is a
private method".
Basically, this code in sipWrapper_init, line 7173:
/*
* If the arguments were parsed without error then assume an
* exception has already been raised for why the instance
* wasn't created.
*/
if (pstate == PARSE_OK)
argsparsed = PARSE_RAISED;
is not executed, because pstate was already mutated a few lines above:
/*
* If the parse was successful but no C/C++ object was
created then
* we assume that handwritten code decided after the parse that
* it didn't want to handle the signature.
*/
if (pstate == PARSE_OK)
pstate = PARSE_TYPE;
I was wondering if it should check "argsparsed == PARSE_OK" (at line
7173) instead of "pstate == PARSE_OK".
Thanks!
