X-Git-Url: https://git.rkrishnan.org/%5B/%5D%20/reliability?a=commitdiff_plain;h=4c592f15054c5a533b1a099702bb5aa85efa8c44;p=tahoe-lafs%2Ftahoe-lafs.git

test_storage.py: test that we are using the filesystem of storage/shares/, rather than storage/, to calculate remaining space, and that the HTML status output reflects the values returned by fileutil.get_disk_stats. This version works with older versions of the mock library. refs #1384
