Subject: 'tahoe debug catalog-shares': sort SIs and shnums
X-Git-Url: https://git.rkrishnan.org/Site/Content/Exhibitors/%22news.html/?a=commitdiff_plain;h=980fb0b2bbb8b8e1f8217084d1e162f7fd85bed4;p=tahoe-lafs%2Ftahoe-lafs.git

'tahoe debug catalog-shares': sort SIs and shnums

Without this, SIs or shnums could be emitted in random order, depending upon
what the filesystem happens to return.
