X-Git-Url: https://git.rkrishnan.org/specifications/%5B/%5D%20/(%5B%5E?a=commitdiff_plain;h=7e64d6021192708c91cc7093f0bcbac3f4e01ae2;p=tahoe-lafs%2Ftahoe-lafs.git

Bug fix: deque must be unbounded

If using a bounded deque then:
"""
Once a bounded length deque is full, when new items are added, a corresponding number of items are discarded from the opposite end.
"""

This bug was introduced at commit 87657eb382da05039cce99862691efcc27243193
