Hi,
Earlier tonight I was installing roundup and ran into the following
trouble while running python -c 'import test;test.go()' (as specified
in the INSTALL.txt):

I'm currently running with a newly installed python 2.1, bsddb3 on a redhat
7.0 machine (I also ripped the python 1.5.2 rpms tonight also) and am wondering
if there's something obvious that I missed or something less obvious that
I can help track down.
thanks in advance and I look forward to poking around with it more,
steve

Hrm, I haven't actually used the bsddb3 backend - I'll see about giving it a
go tomorrow, but I don't like my chances.
Could you try just importing the bsddb3 module and creating a db file in the
interpreter? ie.
>>> import bsddb3
>>> bsddb3.btopen('foo', 'n')
From the traceback, it would seem that the path specified in the btopen call
might include a directory that doesn't exit. Try putting a print in line 71
of back_bsddb3.py and see what it's expecting to create the database in (I
believe that the path wants to point to a file that it can open, if it's like
the other dbms. If a directory needs to be created, we can fairly easily
amend the unit test to do so...

yes, it works fine. I get an 8k file named foo that `file` tells me is
a BerkeleyDB file.

Here is what I added:
if os.path.exists(path):
return bsddb3.btopen(path, mode)
else:
print path
return bsddb3.btopen(path, 'n')
and the tests:
$ python setup.py
Running unit tests...

(the API mismatch for module _db bothers me but I know I built it
cleanly. Also, since I'm able to create databases, I'm not sure what that
problem is all around. fyi, I'm a relative newcomer to the python world)
thoughts?

Well, that looks OK to me. Looking at the code, the path
"/home/stevej/roundup-0.2.3/_test_dir/" must exist - the test case setUp
wouldn't work it it didn't...

From your first mail:

The API mismatch bothers me too. If the module was compiled for python 1.5.2
and then installed by python 2.1, you will get that API mismatch message. It
is possible that is the cause of the problems. I'm not sure what you mean by
"ripped the python 1.5.2 rpms".
Also, is there a chance that the _db module (which is an apalling name, tsk
on the bsddb3 module writer) is duplicated in another package? That is, what
does "find /usr/lib/python2.1 -name _db.so" turn up? It should only find one
module. If you've extended your PYTHONPATH, you'd want to check that too for
instances of the _db.so file.

This was a problem I had with my PYTHONPATH, which was configured for mojonation, which I was using 1.5.2 for (which I am now recompiling with 2.1). But.. even after cleaning out my PYTHONPATH (to include nothing), I still have those same 4 errors, just no mismatch error. Is there a 'preferred' db library to go with? Granted, roundup should work fine with any libarary that correctly wraps bdb but I'd rather have it up and running sooner rather than later. > I'm not sure what you mean by "ripped the python 1.5.2 rpms". whoops! I lost a word there: "out". I removed the pre-installed python distribution before installing python 2.1. > Also, is there a chance that the _db module (which is an apalling name, tsk > on the bsddb3 module writer) is duplicated in another package?

Well, it should work with no troubles using either the anydbm or bsddb backends (anydbm will actually use bsddb through dbhash if it's installed, but not bsddb3). Could you try that and let me know how it goes? I will see about getting bsddb3 installed and try it out. I'm using Mandrake 8.0 with the 2.1.1 rpms from the cooker (which don't include bsddb3, unfortunately). I'm not sure what Anthony's using. Richard |
