[issue31026] test_dbm fails when run directly

[Larry Hastings]

Larry Hastings  added the comment:

For what it's worth, I'm cherry-picking this back into 3.5 for 3.5.8 final.  I 
(finally?) got bit by this, and since the patch is literally only changes in 
the Lib/test directory I consider it safe to merge even after 3.5.8rc2.  (I was 
in a bit of a hurry, I didn't use the Python cherry picker technology, I just 
used "git cherry-pick".)

Serhiy Storchaka  added the comment:

The same error is now occurred in Ubuntu 18.04 by default. 

The proposed patch moves the test for the empty value to separate methods and 
skips them if dbm.ndbm uses Berkeley DB.

Brian Moyles added the comment:

Actually, I was able to make things happy by removing libdb5.3-dev and solely 
relying on libgdbm3-dev (which suggests that Debian upstream may want to pare 
back their build requirements rather than disable the dbm test as they appear 
to do now).

[Brian Moyles]

Brian Moyles added the comment:

I ran into the same problem when running the test suite against a fresh Python 
3.6.2 build on Ubuntu 16.04. It specifically appears to be a problem with ndbm 
and retrieving an empty byte string value:

Python 3.6.2 (default, Sep  8 2017, 18:31:28)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dbm.gnu, dbm.ndbm
>>> g = dbm.gnu.open('gnudb', 'c')
>>> g['0'.encode('ascii')] = b''
>>> g.keys()
[b'0']
>>> g['0'.encode('ascii')]
b''
>>>
>>> n = dbm.ndbm.open('ndbm', 'c')
>>> n['0'.encode('ascii')] = b''
>>> n.keys()
[b'0']
>>> n['0'.encode('ascii')]
Traceback (most recent call last):
  File "", line 1, in 
KeyError: b'0'

Same behavior when using the distribution's stock Python 3.5.2 so I suspect 
there's a behavioral change in libdb that's not accounted for?

OK on Windows, skipping test_whichdb_ndbm (neither _dbm nor _gdbm are present.)

Which dbm implementation are you using? Do you have the following modules?

On my Linux (Fedora 25), "./python Lib/test/test_dbm.py" and "./python -m test 
test_dbm" both succeed.
