Subject: manhole: be more tolerant of authorized_keys. files in .tahoe
X-Git-Url: https://git.rkrishnan.org/vdrive/%5B%5E?a=commitdiff_plain;h=90e3f3717339ec5fc9db62fd2d215c19b11a79b0;p=tahoe-lafs%2Ftahoe-lafs.git

manhole: be more tolerant of authorized_keys. files in .tahoe

both peter and I independently tried to do the same thing to eliminate the
authorized_keys file which was causing problems with the broken mac build
(c.f. #522) namely mv authorized_keys.8223{,.bak}  but the node is, ahem,
let's say 'intolerant' of the trailing .bak - rather than disable the
manhole as one might expect, it instead causes the node to explode on
startup.  this patch makes it skip over anything that doesn't pass the
'parse this trailing stuff as an int' test.
