# mplayer made two simultaneous webapi GET requests: first one for an
# index region at the end of the (mp3/video) file, then one for the
# first block of the file (the order doesn't really matter). All GETs
# failed (NoSharesError) because of the type(__len__)==long bug. Each
# GET submitted a DownloadNode.get_segment() request, which was
# queued by the DN (DN._segment_requests), so the second one was
# blocked waiting on the first one. When the first one failed,
# DN.fetch_failed() was invoked, which errbacks the first GET, but
# left the other one hanging (the lost-progress bug mentioned in
# #1154 comment 10)
#
# Then mplayer sees that the index region GET failed, so it cancels
# the first-block GET (by closing the HTTP request), triggering
# stopProducer. The second GET was waiting in the Deferred (between
# n.get_segment() and self._request_retired), so its
# _cancel_segment_request was active, so was invoked. However,
# DN._active_segment was None since it was not working on any segment
# at that time, hence the error in #1154.

# creates two sets of shares (one for file A, second for file B),
# uploads a combination of them (shares 0-4 of A, 5-9 of B), and then
# builds an otherwise normal UEB around those shares: their goal is
# to give their victim a filecap which sometimes downloads the good A
# contents, and sometimes the bad B contents, depending upon which
# servers/shares they can get to. Having a hash of the ciphertext
# forces them to commit to exactly one version. (Christian's prize
# for finding this problem was a t-shirt with two sides: the shares
# of file A on the front, B on the back).
# creating a set of shares with this property is too hard, although
# it'd be nice to do so and confirm our fix. (it requires a lot of
