Hi all, I am currently using Django on a project with a database of
fairly large table sizes, and I have encountered a strange and
potentially dangerous bug, of which I am not sure the cause. This is
not really a bug report, as I haven't really had the time necessary to
gather enough information to file an official bug report, but I would
like to get some more expert opinions on the matter if I could.

Here goes: Using Django, I am inserting rather large amounts of
records into an sqlite3 database on OS X v10.4.10. I have yet to
perfect my Django development cycle, and so I spend a decent amount of
time changing around models and recreating databases as I develop. At
one point, after spending hours writing to the database, the python
process had finished, however the database still appeared to be empty,
except for the fact that the filesystem thought its size was ~53Mb.
Not having time to investigate further, I deleted the database and
decided to try again later. For a separate part of the project, I
wanted to install matplotlib and pylab, and so I moved on to do this
next instead. However, compilation errors abounded when I did so,
namely that there were odd characters in my system and various other
header files. When I looked at these files, they indeed appeared to
binary, except for the fact that there were visible strings of ASCII
text, which clearly came from the data I had been trying to insert
into the database (strangely enough these were actually DNA sequences,
but not from a virus).

I was able to restore the headers that I needed in order to compile,
however, I have no idea what else on my system may have been touched
by this. Days later I had a problem with import site every time I
would start up python, and found another string of DNA had inserted
itself into my Numeric.pth file. The difficulties so far have been
easy enough to fix, but this is such a strange, and potentially
dangerous problem, that I am cautious about writing to the database
any further until I have identified its cause. I understand that this
is likely a sqlite issue, but if anyone has any further insight it
would be greatly appreciated.

Thanks!
Jared
