Having the git-annex-p2p-<netname> command output the socket filename
left git-annex scrambling to listen to it in order to not miss incoming
connections. And if the command uses something like socat UNIX-CONNECT,
that expects the socket to be accepting connections and errors out when
it's not, that would be a problem.
Rather than complicating the protocol with git-annex needing to send
back a message when it's listening to the socket, simplified it by
having git-annex provide the socket path to the command.
This does mean that, if a P2P network has its own place it expects to
find a socket file, the git-annex-p2p-<netname> command would need to
somehow arrange for it to use the git-annex socket path. A symlink would
be one way to handle that situation.
p2p: Added --enable option, which can be used to enable P2P networks
provided by external commands git-annex-p2p-<netname>
Made git-annex p2p --enable tor behave the same as git-annex enable-tor,
to make tor a bit less of a special case. However, it canot be run as root,
since it cannot take the user id parameter.
This is probably enough to support accessing remotes using p2p-annex:: urls.
Not tested yet of course since there is not yet support for serving the
other side of such a connection, or for setting up such a connection.
P2P.Generic has an implementation of the whole interface to the
git-annex-p2p-<netname> commands.
This is for p2p-annex:: urls that will use the new generic P2P
transport.
In addressCredsFile, threw in an url encoding of any non-alphanumeric
characters that are in the address. This is to avoid any possible path
traversal attacks via a p2p-annex:: url, since the address part of it
could contain any characters. And, went ahead and did the same url
encoding of tor-annex:: urls, even though tor onion addresses are all
alphanumerics, on the off chance that might avoid a similar problem.
(It does not seem likely enough to treat it as a security hole.)
Improved workaround for git 2.50 bug, avoding an occasional test suite
failure, as well as some situations where an unlocked file did not get
populated when adding another file to the repository with the same content.
This uses the alternate code path that was already using when there was
a conflict. Since that code path is not able to record its work,
it will redo the same work next time. If the only way reconcileStaged
is getting run is via the smudge clean filter, that could result in
more and more changes getting processed redundantly each time. Once
some other git-annex command runs and calls reconcileStaged, it
will stop redoing that work. I don't think the extra work will be a
problem.
To match content that is recorded as present in an url.
Note that, this cannot ask remotes to provide an url using whereisKey, like
whereis does. Because preferred content expressions need to match the same
from multiple perspectives, and the remote would not always be available.
That's why the docs say "recorded as present", but still this may be
surprising to some who see an url in whereis output and are surprised they
cannot match on it.
The use of getDownloader is to strip the downloader prefix from urls like
"yt:". Note that, when OtherDownloader is used, this strips the ":" prefix,
and allows matching on those urls too.
This cleans up after the bug that was fixed in commit
6a9e923c74
Object files that were stored in the wrong location are rescued,
and after that any wrong location logs will be fixed by the usual fsck.
Used protectedOutput to set up a umask that makes the socket only
accessible by the current user.
Authentication is still needed when using this option unless it is combined
with --wideopen. It was just simpler to keep authentication separate from
this.
