Subject: change max filesize limit tests
X-Git-Url: https://git.rkrishnan.org/pf/content/en/footer/index.html?a=commitdiff_plain;h=efcc45951d3544ee6b4021a5e46b276e1a3d5adb;p=tahoe-lafs%2Ftahoe-lafs.git

change max filesize limit tests

Instead of testing to see that the previous SDMF filesize limit was being
obeyed, we now test to make sure that we can insert files larger than that
limit.
