As I was about to add another I realised that a generic +database module was called for to replace all the ad-hoc bits. + +I based the interface on gdbm.

The tdb_open call is more similar to a + traditional open() +- no tdbm_reorganise() function +- no tdbm_sync() function. No operations are cached in the library anyway +- added a tdb_traverse() function for traversing the whole database +- added transactions support + +A general rule for using tdb is that the caller frees any returned +TDB_DATA structures.

Also, since swig_type_info structures store pointers to + * swig_cast_info structures and swig_cast_info structures store pointers back + * to swig_type_info structures, we need some lookup code at initialization. + * The idea is that swig generates all the structures that are needed. + * The runtime then collects these partially filled structures. + * The SWIG_InitializeModule function takes these initial arrays out of + * swig_module, and does all the lookup, filling in the swig_module.types + * array with the correct data and linking the correct swig_cast_info + * structures together. + * + * The generated swig_type_info structures are assigned staticly to an initial + * array. We just loop through that array, and handle each type individually. + * First we lookup if this type has been already loaded, and if so, use the + * loaded structure instead of the generated one. Then we have to fill in the + * cast linked list. The cast data is initially stored in something like a + * two-dimensional array. Each row corresponds to a type (there are the same + * number of rows as there are in the swig_type_initial array). Each entry in + * a column is one of the swig_cast_info structures for that type. + * The cast_initial array is actually an array of arrays, because each row has + * a variable number of columns. So to actually build the cast linked list, + * we find the array of casts associated with the type, and loop through it + * adding the casts to the list. The one last trick we need to do is making + * sure the type pointer in the swig_cast_info struct is correct. + * + * First off, we lookup the cast->type name to see if it is already loaded. + * There are three cases to handle: + * 1) If the cast->type has already been loaded AND the type we are adding + * casting info to has not been loaded (it is in this module), THEN we + * replace the cast->type pointer with the type pointer that has already + * been loaded. + * 2) If BOTH types (the one we are adding casting info to, and the + * cast->type) are loaded, THEN the cast info has already been loaded by + * the previous module so we just ignore it. + * 3) Finally, if cast->type has not already been loaded, then we add that + * swig_cast_info to the linked list (because the cast->type) pointer will + * be correct. + * ----------------------------------------------------------------------------- */ + +#ifdef __cplusplus +extern "C" { +#if 0 +} /* c-mode */ +#endif +#endif + +#if 0 +#define SWIGRUNTIME_DEBUG +#endif + + +SWIGRUNTIME void +SWIG_InitializeModule(void *clientdata) { + size_t i; + swig_module_info *module_head, *iter; + int found, init; + + clientdata = clientdata; + + /* check to see if the circular list has been setup, if not, set it up */ + if (swig_module.next==0) { + /* Initialize the swig_module */ + swig_module.type_initial = swig_type_initial; + swig_module.cast_initial = swig_cast_initial; + swig_module.next = &swig_module; + init = 1; + } else { + init = 0; + } + + /* Try and load any already created modules */ + module_head = SWIG_GetModule(clientdata); + if (!module_head) { + /* This is the first module loaded for this interpreter */ + /* so set the swig module into the interpreter */ + SWIG_SetModule(clientdata, &swig_module); + module_head = &swig_module; + } else { + /* the interpreter has loaded a SWIG module, but has it loaded this one?
