[Python-bugs-list] [Bug #110612] anydbm can't handle dumbdbm (PR#200)

[noreply@sourceforge.net]

Bug #110612, was updated on 2000-Jul-31 14:05
Here is a current snapshot of the bug.

Project: Python
Category: Library
Status: Open
Resolution: Fixed
Bug Group: None
Priority: 5
Summary: anydbm can't handle dumbdbm (PR#200)

Details: Jitterbug-Id: 200
Submitted-By: aa8vb@yahoo.com
Date: Wed, 9 Feb 2000 13:05:57 -0500 (EST)
Version: 1.5.2
OS: IRIX 6.5


Basically, anydbm won't open dumbdbm files that anydbm created.

   >>> import anydbm
   >>> db = anydbm.open( "database", "c" )
   >>> db[ "1" ] = "one"
   >>> db.close()
   >>> db = anydbm.open( "database", "r" )
   Traceback (innermost last):
     File "<stdin>", line 1, in ?
     File "/home/rhh/software/python-1.5.2/lib/python1.5/anydbm.py", line 80,
in
 open
       raise error, "need 'c' or 'n' flag to open new db"
   anydbm.error: need 'c' or 'n' flag to open new db

More details can be found in the c.l.python thread "anydbm - a simple
question".

I searched for a matching bug and didn't find one in the database.  Also,
I verified my whichdb.py matches what's currently in CVS, so I don't think
this has been fixed yet.

Thanks,

Randall

Comment:
It was a simple glitch in whichdb -- it didn't recognize the
dumbdbm format. Fixed it.

I think this bug has appeared again. I get the exact same error with Python 1.6, but it works with 1.5.2.

Reopened and assigned to Jeremy since a comment claims it's reappeared in 1.6.  Can you check 2.0?

Comment:
The following script works for me, in 2.0b1

>>> import dumbdbm
>>> dumbdbm.open("/tmp/hhh","c")
<dumbdbm._Database instance at 0x829eaac>
>>> s=_
>>> s['a']='b'
>>> s.close()
>>> import whichdb
>>> whichdb.whichdb("/tmp/hhh")
'dumbdbm'
>>> import anydbm
>>> s=anydbm.open("/tmp/hhh")
>>> s

So it works for me, on i586-pc-linux-gnu.
