I think I've seen this too when running the bsddb3 unittest. I think it's caused by a previous test ending badly and leaving junk behind that the test suite doesn't properly remove before starting. But I don't recall the details. --Guido On Dec 5, 2007 5:24 PM, Gregory P. Smith wrote:

I'd expect 4.5 to work fine but I don't know why you're getting such a strange error, i've never seen that. fwiw i suggest people avoid berkeleydb 4.6 for now.

I noticed that test_anydbm and test_bsddb seemed to hang, so I -x'd them. Later on while test_whichdb was running and I was off doing something else (so didn't notice the delay), it eventually spewed this traceback:

Traceback (most recent call last): File "/Users/skip/src/python/trunk/Lib/test/test_whichdb.py", line 49, in test_whichdb_name f = mod.open(_fname, 'c') File "/Users/skip/src/python/trunk/Lib/dbhash.py", line 16, in open return bsddb.hashopen(file, flag, mode) File "/Users/skip/src/python/trunk/Lib/bsddb/__init__.py", line 310, in hashopen d.open(file, db.DB_HASH, flags, mode) DBFileExistsError: (17, 'File exists -- __fop_file_setup: Retry limit (100) exceeded')

Looking at _bsddb.so I see it's linked against Berkeley DB 4.5. This is on Mac OSX 10.4.11 using the MacPorts version of Berkeley DB (4.5.20). Have I somehow strayed out of the support cocoon without realizing it? I wouldn't have thought so, since the max version listed in setup.py is 4.6.

Thx,
