Darn; this test works when you run test_pty.py directly, but fails when regrtest runs it (the os.read() raises os.error).  I can't figure out the cause, so am commenting out the test.

[Patch #827559 from Chris Gonnerman] Make SimpleHTTPServer redirect when a directory URL is missing the trailing slash; this lets relative links work.

the master should close the slave fd.

Added a test to test_pty.py that reads from the master_fd after doing
a pty.fork(); without the fix it hangs forever instead of raising an
exception.  (<crossing fingers for the buildbots>)

Is there really no other way to read the umask than to set it?

2.5 bugfix candidate, maybe; arguably this patch changes the API of
dumbdbm and shouldn't be added in a point-release.

that should really be 'iterable'; this commit changes them.

Did I miss any?  Did I introduce any errors?

Add length checking to single-file mailbox formats: before doing a
flush() on a mailbox, seek to the end and verify its length is
unchanged, raising ExternalClashError if the file's length has
changed.

This fix avoids potential data loss if some other process appends to
the mailbox file after the table of contents has been generated;
instead of overwriting the modified file, you'll get the exception.

I also noticed that the self._lookup() call in self.flush() wasn't
necessary (everything that sets self._pending to True also calls
self.lookup()), and replaced it by an assertion.

2.5 backport candidate.

Needs to be backported.
