* https://github.com/ghaering/pysqlite/commit/3567b31bb5e5b226ba006213a9c69dde3f155faf

With the following additions:

* Made the string comparison a little more robust

Update current tests that use old pattern with assertRaises
to make them more maintainable.

  #1733757: the interpreter would hang on shutdown, if the function set by sys.settrace
  calls threading.currentThread.

  The correction somewhat improves the code, but it was close.
  Many thanks to the "with" construct, which turns python code into C calls.

  I wonder if it is not better to sys.settrace(None) just after
  running the __main__ module and before finalization.

  Prevent test_sqlite from hanging on older versions of sqlite.
  The problem is that when trying to do the second insert, sqlite seems to sleep
  for a very long time.  Here is the output from strace:

    read(6, "SQLite format 3\0\4\0\1\1\0@  \0\0\0\1\0\0\0\0"..., 1024) = 1024
    nanosleep({4294, 966296000},  <unfinished ...>

  I don't know which version this was fixed in, but 3.2.1 definitely fails.

left out the stuff about creating a connection object from a APSW connection.

  Issue 705836: Fix struct.pack(">f", 1e40) to behave consistently
  across platforms:  it should now raise OverflowError on all
  platforms.  (Previously it raised OverflowError only on
  non IEEE 754 platforms.)

  Also fix the (already existing) test for this behaviour
  so that it actually raises TestFailed instead of just
  referencing it.

should prevent a failure in tearDown masking any real test failure.

number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

This is based on pysqlite2.1.3, and provides a DB-API interface in
the standard library. You'll need sqlite 3.2.2 or later to build
this - if you have an earlier version, the C extension module will
not be built.
