zooko on irc:
> sigh, I am experiencing failure using the pub test grid :-/
> My top-level directory contains some subdir or subdir of subdir which is
unrecoverable.
> Therefore, as far as I know, the Tahoe-LAFS UIs provide almost no way to
proceed.
> I can't deep-repair, I can't cp -r to recover the recoverable stuff.
> Maybe I can deep-check to learn which one is unrecoverable ...
ticket:755#comment:4 mentions this problem, but that ticket is mainly
about having deep-check continue on error. Giving information about which
file is unrecoverable (the cap, and the filename if known) would be useful
in more circumstances than just deep-check.
Note that because of #625, we need a write cap to repair mutable
files/directories. Otherwise I would suggest diminishing the cap in the
message to a read or verify cap (since the error message channel might be
more vulnerable to cap leakage). As it is, the user needs the write cap,
at least for mutable objects.
