One benefit of this is that a typo in annex-cluster-node config won't
init a new cluster.
Also it gets the cluster description set and is consistent with
initremote.
These remotes have no url configured, so git pull and push will fail.
git-annex sync --content etc can still sync with them otherwise.
Also, avoid git syncing twice with the same url. This is for cases where
a proxied remote has been manually configured and so does have a url.
Or perhaps proxied remotes will get configured like that automatically
later.
This does mean a redundant write to the git-annex branch. But,
it means that two clients can be using the same proxy, and after
one sends a file to a proxied remote, the other only has to pull from
the proxy to learn about that. It does not need to pull from every
remote behind the proxy (which it couldn't do anyway as git repo
access is not currently proxied).
Anyway, the overhead of this in git-annex branch writes is no worse
than eg, sending a file to a repository where git-annex assistant
is running, which then sends the file on to a remote, and updates
the git-annex branch then. Indeed, when the assistant also drops
the local copy, that results in more writes to the git-annex branch.
This just happened to work correctly. Rather surprisingly. It turns out
that openP2PSshConnection actually also supports local git remotes,
by just running git-annex-shell with the path to the remote.
Renamed "P2PSsh" to "P2PShell" to make this clear.
Still need to implement GET and PUT, and will implement CONNECT and
NOTIFYCHANGE for completeness.
All ServerMode checking is implemented for the proxy.
There are two possible approaches for how the proxy sends back messages
from the remote to the client. One would be to have a background thread
that reads messages and sends them back as they come in. The other,
which is being implemented so far, is to read messages from the remote
at points where it is expected to send them, and relay back to the
client before reading the next message from the client. At this point,
I'm unsure which approach would be better.
The need for proxynoresponse to be used by UNLOCKCONTENT, for example,
builds protocol knowledge into the proxy which it would not need with
the other method.
connRepo is only used when relaying git upload-pack and receive-pack.
That's only supposed to be used when git-annex-remotedaemon is serving
git-remote-tor-annex connections over tor. But, it was always set, and
so could be used in other places possibly.
Fixed by making connRepo optional in the P2P protocol interface.
In Command.EnableTor, it's not needed, because it only speaks the
protocol in order to check that it's able to connect back to itself via
the hidden service. So changed that to pass Nothing rather than the git
repo.
In Remote.Helper.Ssh, it's connecting to git-annex-shell p2pstdio,
so is making the requests, so will never need connRepo.
In git-annex-shell p2pstdio, it was accepting git upload-pack and
receive-pack requests over the P2P protocol, even though nothing sent
them. This is arguably a security hole, particularly if the user has
set environment variables like GIT_ANNEX_SHELL_LIMITED to prevent
git push/pull via git-annex-shell.
Check explicitly for an annex:: url, not just any url. While no built-in
special remotes set an url, except ones that can be synced with, it
seems possible that some external special remote sets an url for its own
use, but did not expect it to be used by git-annex sync et al.
The assistant also syncs with them.
This turns out to only be necessary is edge cases. Most of the
time, git-annex unused --from remote doesn't see git-remote-annex keys
at all, because it does not record a location log for them.
On the other hand, git-annex unused does find them, since it does not
rely on the location log. And that's good because they're a local cache
that the user should be able to drop.
If, however, the user ran git-annex unused and then git-annex move
--unused --to remote, the keys would have a location log for that
remote. Then git-annex unused --from remote would see them, and would
consider them unused. Even when they are present on the special remote
they belong to. And that risks losing data if they drop the keys from
the special remote, but didn't expect it would delete git branches they
had pushed to it.
So, make git-annex unused --from skip git-remote-annex keys whose uuid
is the same as the remote.
fsck --fast was intended to disable checksumming, but checksumming is done
after transfers too. Due to the check being in the non-incremental path,
it would only affect non-incremental checksumming during a transfer,
and I'm not 100% sure that it was a problem.
Also, when using an external backend that does checksumming, fsck --fast
didn't disable it and now does.
Not quite there yet.
Also, changed the format of GITBUNDLE keys to use only one '-'
after the UUID. A sha256 does not contain that character, so can just
split at the last one.
Amusingly, the sha256 will probably not actually be verified. A git
bundle contains its own checksums that git uses to verify it. And if
someone wanted to replace the content of a GITBUNDLE object, they
could just edit the manifest to use a new one whose sha256 does verify.

This reverts commit cee12f6a2f.
This commit broke git-annex init run in a repo that was cloned from a
repo with an adjusted branch checked out.
The problem is that findAdjustingCommit was not able to identify the
commit that created the adjusted branch. It seems that there is an extra
"\n" at the end of the commit message that it does not expect.
Since backwards compatability needs to be maintained, cannot just make
findAdjustingCommit accept it with the "\n". Will have to instead
have one commitTree variant that uses the old method, and use it for
adjusted branch committing.
sync, assist, import: Allow -m option to be specified multiple times, to
provide additional paragraphs for the commit message.
The option parser didn't allow multiple -m before, so there is no risk of
behavior change breaking something that was for some reason using multiple
-m already.
Pass through to git commands, so that the method used to assemble the
paragrahs is whatever git does. Which might conceivably change in the
future.
Note that git commit-tree has supported -m since git 1.7.7. commitTree
was probably not using it since it predates that version. Since the
configure script prevents building git-annex with git older than 2.1,
there is no risk that it's not supported now.

A recent change made plumbing the backend through fsck unncessary.
Left fsck checking backend and skipping operating on key when it could
not find one. Not checking the backend would be a behavior change.
For example the command git-annex fsck --key FOO--bar does nothing
since FOO is not a known backend. If this were removed it would
instead go on and fsck it and warn that no copies exist of the key.
That behavior change seems like it would be fine, but I also have no
reason to make it.

When a file in the export is renamed, and the remote's renameExport
returned Nothing, renaming to the temp file would first say it was
renaming, and appear to succeed, but actually what it did was delete the
file. Then renaming from the temp file would not do anything, since the
temp file is not present on the remote. This appeared as if a file got
renamed to a temp file and left there.
Note that exporttree=yes importree=yes remotes have their usual
renameExport replaced with one that returns Nothing. (For reasons
explained in Remote.Helper.ExportImport.) So this happened
even with remotes that support renameExport.
Fix by letting renameExport = Nothing when it's not supported at all.
This avoids displaying the rename.

What this can currently be used for is only to change an url from being
used by a special remote to being used by the web remote.
This could have been a --move-from option to registerurl. But, that would
have complicated its option and --batch processing, and also would have
complicated unregisterurl, which is implemented on top of
Command.Registerurl. So, a separate command was actually less complicated
to implement.
The generic description of the command is because I want to make this
command a catch-all for other url updating kind of things, if there are
ever any more. Also because it was hard to come up with a good name for the
specific action. I considered `git-annex moveurl`, but that seems to
indicate data is perhaps actually being moved, and seems to sit at the same
level as addurl and rmurl, and this command is at the plumbing
level of registerurl and unregisterurl.

This needs the content to be present in order to hash it. But it's not
possible for a module used by Backend.URL to call inAnnex because that
would entail a dependency loop. So instead, rely on the fact that
Command.Migrate calls inAnnex before performing a migration.
But, Command.ExamineKey calls fastMigrate and the key may or may not
exist, and it's not wanting to actually perform a migration in any case.
To handle that, had to add an additional value to fastMigrate to
indicate whether the content is inAnnex.
Factored generateEquivilantKey out of Remote.Web.
Note that migrateFromURLToVURL hardcodes use of the SHA256E backend.
It would have been difficult not to, given all the dependency loop
issues. But --backend and annex.backend are used to tell git-annex
migrate to use VURL in any case, so there's no config knob that
the user could expect to configure that.

git-annex fsck and some other commands that verify the content of a key
were using the non-incremental verification interface. But for VURL
urls, that interface is innefficient because when there are multiple
equivilant keys, it has to separately read and checksum for each key in
turn until one matches. It's more efficient for those to use the
incremental interface, since the file can be read a single time.
There's no real downside to using the incremental interface when available.
Note that more speedup could be had for VURL, if it was able to
calculate the checksum a single time and then compare with the
equivilant keys checksums. When the equivilant keys use the same type of
checksum.

Not yet implemented is recording hashes on download from web and
verifying hashes.
addurl --verifiable option added with -V short option because I
expect a lot of people will want to use this.
It seems likely that --verifiable will become the default eventually,
and possibly rather soon. While old git-annex versions don't support
VURL, that doesn't prevent using them with keys that use VURL. Of
course, they won't verify the content on transfer, and fsck will warn
that it doesn't know about VURL. So there's not much problem with
starting to use VURL even when interoperating with old versions.

Except when a commit is made in a view, which changes metadata.
Make the assistant commit the git-annex branch after git commit of working
tree changes.
This allows using the annex.commitmessage-command in the assistant to
generate a commit message for the git-annex branch that relies on state
gathered during the commit of the working tree. Eg, it might reuse the
commit message.
Note that, when not using the assistant, a git-annex add still commits
the git-annex branch, so such a annex.commitmessage-command set up would
not work then. But if someone is using the assistant and wants
programmatic control over commit messages, this is useful. Someone not
using the assistant can get the same result by using annex.alwayscommit=false
during the git-annex add, and git-annex merge after they git commit.
pre-commit was never really intended to commit the git-annex branch
(except after recording changed metadata), but the assistant did sort of
rely on it. It does later commit the git-annex branch before pushing to
remotes, but I didn't want to risk building up lots of uncommitted changes
to it if that didn't happen frequently.

Was doing a Git.Branch.commit for historical reasons to do with direct
mode, which no longer apply.
Note that the preCommitAnnexHook is no longer called in commitStaged
because git-annex installs a pre-commit hook that runs the pre-commit-annex
hook. And git commit will run the pre-commit hook.

--raw-except=web allows using yt-dlp but not any other special remotes.
Currently this option can only be used once, trying to use it repeatedly
will make option parsing fail. Perhaps it ought to support being used more
than once, but it seemed like an unlikely use case to need that.
Note that getParsed is called repeatedly when the option is used with
several urls. While implementing DeferredParseClass would avoid that
innefficiency, it didn't seem worth the added boilerplate since
getParsed only calls byNameWithUUID which does minimal work.

importfeed --force: Don't treat it as a failure when an already downloaded
file exists. (Fixes a behavior change introduced in 10.20230626.)
04ee6c4c6b caused the reversion. Inside a CommandPerform, stop causes it
to fail. Before that commit, it was inside a CommandStart, where stop
causes it to skip.
Which uses yt-dlp to screen scrape the equivilant of an RSS feed.
Note that youtubedlscraped is a speed optimisation. Since yt-dlp found
the urls, we know it can download them. That avoids calling
youtubeDlSupported on each url, which makes --fast a lot faster.
Almost all the same metadata fields and file formatting fields are
populated, when yt-dlp is able to get the data. Note that yt-dlp has some
additional useful metadata that could be exposed. But, much of it is
specific to particular websites, and it would be hard to document on the
git-annex importfeed man page.
