Not yet tested and places git-annex-shell is run need to be modified to
pass the new field settings.
Note that rsyncServerSend was changed to fork, rather than directly exec
rsync, because it needs to keep the transfer lock held, and clean up the
transfer log when done.
In order to record a semi-useful filename associated with the key,
this required plumbing the filename all the way through to the remotes'
storeKey and retrieveKeyFile.
Note that there is potential for deadlock here, narrowly avoided.
Suppose the repos are A and B. A sends file foo to B, and at the same
time, B gets file foo from A. So, A locks its upload transfer info file,
and then locks B's download transfer info file. At the same time,
B is taking the two locks in the opposite order. This is only not a
deadlock because the lock code does not wait, and aborts. So one of A or
B's transfers will be aborted and the other transfer will continue.
Whew!
storing it in remotes/web/xx/yy/foo.log meant lots of extra directory
objects in git. Now I use xx/yy/foo.log.web, which is just as unique, but
more efficient since foo.log is there anyway.
Of course, it still looks in the old location too.
This overrides the trust.log, and is overridden by the command-line trust
parameters.
It would have been nicer to have Logs.Trust.trustMap just look up the
configuration for all remotes, but a dependency loop prevented that
(Remotes depends on Logs.Trust in several ways). So instead, look up
the configuration when building remotes, storing it in the same forcetrust
field used for the command-line trust parameters.
This needs to run git log on the location log files to get at all past
versions of the file, which tends to be a bit slow.
It would be possible to make a version optimised for showing the location
logs for every key. That would only need to run git log once, so would be
faster, but it would need to process an enormous amount of data, so
would not speed up the individual file case.
In the future it would be nice to support log --format. log --json also
doesn't work right yet.
semitrusted uuids rarely are listed in trust.log, so a special case
is needed to get a list of them. Take the difference of all known uuids
with non-semitrusted uuids.
Avoid ever using read to parse a non-haskell formatted input string.
show :: Key is arguably still show abuse, but displaying Keys as filenames
is just too useful to give up.
Checks location log information, and file contents.
Does not check that numcopies is satisfied, as .gitattributes information
about numcopies is not available in a bare repository. In practice, that
should not be a problem, since fsck is also run in a checkout and will
check numcopies there.
