Hi,
I notice that in PEP 3108 the dbm modules are going to be in package dbm:
New Old ----------- -------------------------------------------- dbm.tools anydbm + whichdb dbm.db db.hash (actually bsd db so presumably using bsddb.hashopen() behind the scenes?) dbm.ndbm dbm dbm.dumb dumbdbm dbm.gnu gdbm
This leaves bsddb as a separate package. As far as I can tell bsddb is not so different from the others. I presume (although the documentation for bsddbobject.keys() denies it) that btopen() gives lexicographical ordering and rnopen() give insertion order ordering by keys, whereas hashopen() is unordered like a dict and like the other dbms provided.
In any case the name dbm.db seems wrong to me (too generic when the others are specific to their dbm type), so at the least shouldn't dbm.db be renamed dbm.bsd?
Good point. Anyone object to that renaming?
If consistency were wanted, dbm.bsd.open() could be a wrapper for dbm.bsd.hashopen() but only with filenname, flag and mode arguments so as to match the other dbms, and with dbm.bsd.hashopen(), dbm.bsd.btopen() and dbm.bsd.rnopen() and the other bsddb-specific functions available in the module as usual?
Adding new functions is beyond the reorganization of the stdlib. But it could be considered as a separate idea. -Brett
