Hi all.
OS: Tru64 UNIX 4.0d
PG: PostgreSQL v7.4.1
PY: Python v2.3.3
I just ran into a minor bug while compiling PL/Python module. It bombed out on lines 153 and 160 of ./src/pl/plpython/plpython.c complaining on incomplete type "PyObject_HEAD".
The source of the problem were these two typedefs:
typedef struct PLyPlanObject
{
PyObject_HEAD;
void *plan; /* return of an SPI_saveplan */
int nargs;
Oid *types;
Datum *values;
PLyTypeInfo *args;
} PLyPlanObject;
typedef struct PLyResultObject
{
PyObject_HEAD;
/* HeapTuple *tuples; */
PyObject *nrows; /* number of rows returned by query */
PyObject *rows; /* data rows, or None if no data returned */
PyObject *status; /* query status, SPI_OK_*, or SPI_ERR_* */
} PLyResultObject;
The problem is in ";" following "PyObject_HEAD". "PyObject_HEAD" is a macro defined as:
#define PyObject_HEAD \
_PyObject_HEAD_EXTRA \
int ob_refcnt; \
struct _typeobject *ob_type;
So, that in turn expanded to this:
typedef struct PLyResultObject
{
int ob_refcnt ; struct _typeobject * ob_type ; ;
PyObject *nrows;
PyObject *rows;
PyObject *status;
} PLyResultObject;
The problem is in that extra semicolon - it is an excess and when removed everything compiles OK. Using this in a regular local variable declaration will not cause problems, since an extra ";" will just be swallowed as an NoOp.
Nix.
