"""
Sort wikis in reverse order of last successful dump and return
tuples of information for each wiki:
* whether the dump failed,
* the date of the run as found in dump dir string OR
as determined by time of status file, if use_status_time is True,
* age of status file if any,
* wiki name
Order is (DumpFailed, Age), and False < True:
First, wikis whose latest dump was successful, most recent dump first
Then, wikis whose latest dump failed, most recent dump first.
Finally, wikis which have never been dumped.
According to that sort, the last item of this list is, when applicable,
the oldest failed dump attempt.
If some error occurs checking a dump status, that dump is put last in the
list (sort value is (True, maxsize) )
Note that we now sort this list by the date of the dump directory, not the
last date that a dump file in that directory may have been touched. This
allows us to rerun jobs to completion from older runs, for example
an en pedia history urn that failed in the middle, without borking the
index page links.
