[issue22964] dbm.open(..., "x")

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Agree with Batuhan. There are three dbm implementations in the stdlib: dumb, 
ndbm and gnu. It may be possible to implement the "x" flag in the former two, 
but gdbm_open() does not support it.

Since by default the implementation is chosen automatically in dbm.open(), I do 
not think it is practically to implement a flag which do not work with all 
implementations.

Batuhan  added the comment:

Python directly passes flags to gdbm (or whatever the dbm interface is). 

gdbm_open((char *)file, 0, flags, mode, NULL)) # _gdbmmodule.c:76

I dont think it is good idea to wrap gdbm for just a flag.

New submission from Antony Lee:

It would be nice if dbm.open() supported the x flag that open() now supports 
(create a new db, failing if it already exists).
