Subject: fileutil.write: accept mode=, and use it in Node.write_config
X-Git-Tag: allmydata-tahoe-1.10a1~5
X-Git-Url: https://git.rkrishnan.org/specifications/class-simplejson.JSONDecoder.html?a=commitdiff_plain;h=ff64a0fef5879d3651bc3db6ca0522d96b217d45;p=tahoe-lafs%2Ftahoe-lafs.git

fileutil.write: accept mode=, and use it in Node.write_config

I want mode="w" (i.e. text, with newline conversion) for code that
writes newline-terminated strings (which should also be human readable)
to files. I like to use things like "cat .tahoe/permutation-seed"
without seeing the seed jammed together with the next command prompt.
