Fix a reversion that made dead keys not be skipped when operating on all
keys via --all or in a bare repo. (Introduced in version 8.20200720)
Also, improved the documentation of git-annex-dead, it does not only apply
to fsck --all.
Also, made git-annex fsck, when run on a file whose key is dead, display
that. Before, it displayed that only when run with --all, but with this
fix, it skips dead keys with --all. But it can still be run on a file that
uses a dead key, and displaying "This key is dead" explains to the user
why it does not consider missing content for it to be a problem.

Use curl for downloads from git remotes when annex.url-options and other
git configs are set.
If the url needs a password, curl will fail, and git credential will not be
used to prompt for it. But the user can set --netrc in url-options and
put the password in the netrc file.
This also means that url-options settings like -4 will take effect.
That was the case before commit 1883f7ef8f
forced conduit to be used.
When accessing a git remote over http needs a git credential prompt for a
password, cache it for the lifetime of the git-annex process, rather than
repeatedly prompting.
The git-lfs special remote already caches the credential when discovering
the endpoint. And presumably commands like git pull do as well, since they
may download multiple urls from a remote.
The TMVar CredentialCache is read, so two concurrent calls to
getBasicAuthFromCredential will both prompt for a credential.
There would already be two concurrent password prompts in such a case,
and existing uses of `prompt` probably avoid it. Anyway, it's no worse
than before.
Fix crash importing from a directory special remote that contains a broken
symlink.
The crash was in listImportableContentsM but some other places in
Remote.Directory also seemed like they could have the same problem.
Also audited for other places that have such a problem. Not all calls
to getFileStatus are bad, in some cases it's better to crash on something
unexpected. For example, `git-annex import path` when the path is a broken
symlink should crash, the same as when it does not exist. Many of the
getFileStatus calls are like that, particularly when they involve
.git/annex/objects which should never have a broken symlink in it.
Fixed a few other possible cases of the problem.

Trick the linker into not doing unncessary work searching for optimised
libraries that are not present, by symlinking the directories where
optimised libs would be to the main lib dir.
This reduces the ENOENT of git-annex init by about 1/2. The linker always
finds the files where it looks first time now. I have not looked at what
the wall clock speedup might be, it's probably rather small.
If a x86-64-v5 comes to be, the list will need to be extended. And there
may be other directories used on some machines that I have missed. Not done

For some reason, cabal 3.4.1.0 builds w/o the assistant and webapp,

inside the if flag section to the main build-depends somehow fixes this.
Since the webapp build deps are thus always available, there is no reason
not to build the webapp when building the assistant. So, got rid of the
webapp build flag. Kept the assistant build flag for now, since building
without it does at least still speed up the build.

Too big a footgun.
This does not prevent attackers who can write to the directory being
imported from racing the check. But they can cause anything to be imported
anyway, so would be limited to getting the legacy import to follow into a

(The directory special remote does not have that problem since it does not
move files.)

WIP: This is mostly complete, but there is a problem: createDirectoryUnder
throws an error when annex.dbdir is set to outside the git repo.
annex.dbdir is a workaround for filesystems where sqlite does not work,
due to eg, the filesystem not properly supporting locking.
It's intended to be set before initializing the repository. Changing it
in an existing repository can be done, but would be the same as making a
new repository and moving all the annexed objects into it. While the
databases get recreated from the git-annex branch in that situation, any
information that is in the databases but not stored in the branch gets
lost. It may be that no information ever gets stored in the databases
that cannot be reconstructed from the branch, but I have not verified
that.

When v9/v10 were added, making v8 automatically upgrade was deferred

This caused git to complain that filter-process failed and kill it with

git did not expect, and so git saw an unexpected response to the next

Luckily, filter-process is only used by default in v9 and up, and v8 is
still the default. Also, git had to be updating an empty file, followed
by another file, which is a fairly unlikely situation. And git restarts
filter-process after this happens and uses it to filter the rest of the

When adding a small file, it does not get locked down, so can be modified

The remaining callers all did not rely on it checking gitignore, so were
easy to convert.
They were susceptable to the same overwrite race as add and fix,
although less likely to have it and a narrower window than add's race.
Command.Rekey in passing got an unncessary call to removeFile deleted.
addSymlink handles deleting any existing worktree file.
Similar to git-annex add, git-annex fix queued git add, so if a file
got modified before git add ran, the wrong content would be staged,
perhaps a large file content.
Sponsored-by: Brock Spratlen on Patreon
This is not a complete fix for all such races, only the one where a
large file gets changed while adding and gets added to git rather than
to the annex.
addLink needs to go away, any caller of it is probably subject to the
same kind of race. (Also, addLink itself fails to check gitignore when
symlinks are not supported.)
ingestAdd no longer checks gitignore. (It didn't check it consistently
before either, since there were cases where it did not run git add!)
When git-annex import calls it, it's already checked gitignore itself
earlier. When git-annex add calls it, it's usually on files found
by withFilesNotInGit, which handles checking ignores.
There was one other case, when git-annex add --batch calls it. In that
case, old git-annex behaved rather badly, it would seem to add the file,
but git add would later fail, leaving the file as an unstaged annex symlink.
That behavior has also been fixed.

rather than matching path of an existing remote to find the uuid.
The main benefit of this is that locations not using ssh:// will work
now, including both paths and host:/path
The other benefit is that it's a simpler interface, no need to have an
existing remote with the same url and some other name. Although that
will still work of course.
This does rely on tryGitConfigRead working when given a Git.Repo that is
not a remote. Luckily, it works fine that way.
Also, tryGitConfigRead will auto-init a local repo that has a git-annex
branch. I did not enable auto-init of ssh repos though.
The uuid discovery actually happens twice; initremote discovers it,
and uses it to store the special remote config, but does not set it in the
git remote it creates. So the next run of git-annex does uuid discovery
again, and caches it that time. This could be improved for a tiny
speedup, but I didn't want to complicate things for that in this
commit.

enabled or not. And it can be used with --json.

Deal with git's recent changes to fix CVE-2022-24765, which prevent using
git in a repository owned by someone else.
That makes git config --list not list the repo's configs, only global
configs. So annex.uuid and annex.version are not visible to git-annex.
It displayed a message about that, which is not right for this situation.
Detect the situation and display a better message, similar to the one other
git commands display.
Also, git-annex init when run in that situation would overwrite annex.uuid
with a new one, since it couldn't see the old one. Add a check to prevent
it running too in this situation. It may be that this fix has security
implications, if a config set by the malicious user who owns the repo
causes git or git-annex to run code. I don't think any git-annex configs
get run by git-annex init. It may be that some git config of a command
does get run by one of the git commands that git-annex init runs. ("git
status" is the command that prompted the CVE-2022-24765, since
core.fsmonitor can cause it to run a command). Since I don't know how
to exploit this, I'm not treating it as a security fix for now.
Note that passing --git-dir makes git bypass the security check. git-annex
does pass --git-dir to most calls to git, which it does to avoid needing
chdir to the directory containing a git repository when accessing a remote.
So, it's possible that somewhere in git-annex it gets as far as running git
with --git-dir, and git reads some configs that are unsafe (what
CVE-2022-24765 is about). This seems unlikely, it would have to be part of
git-annex that runs in git repositories that have no (visible) annex.uuid,
and git-annex init is the only one that I can think of that then goes on to
run git, as discussed earlier. But I've not fully ruled out there being
others..
The git developers seem mostly worried about "git status" or a similar
command implicitly run by a shell prompt, not an explicit use of git in
such a repository. For example, Ævar Arnfjörð Bjarma wrote:

The repair code checks to find bad refs by trying to run `git log` on

Ignore annex.numcopies set to 0 in gitattributes or git config, or by
git-annex numcopies or by --numcopies, since that configuration would make
git-annex easily lose data. Same for mincopies.
This is a continuation of the work to make data only be able to be lost
when --force is used. It earlier led to the --trust option being disabled,
and similar reasoning applies here.
Most numcopies configs had docs that strongly discouraged setting it to 0
anyway. And I can't imagine a use case for setting to 0. Not that there
might not be one, but it's just so far from the intended use case of
git-annex, of managing and storing your data, that it does not seem like
it makes sense to cater to such a hypothetical use case, where any
git-annex drop can lose your data at any time.
Using a smart constructor makes sure every place avoids 0. Note that this
does mean that NumCopies is for the configured desired values, and not the
actual existing number of copies, which of course can be 0. The name
configuredNumCopies is used to make that clear.

Directory special remotes with importtree=yes have changed to once more
take inodes into account. This will cause extra work when importing from a

To avoid that extra work, set ignoreinodes=yes when initializing a new
directory special remote, or change the configuration of your existing
remote: git-annex enableremote foo ignoreinodes=yes
This will mean a one-time re-import of all contents from every directory
special remote due to the changed setting.
73df633a62 thought
it was too unlikely that there would be modifications that the inode number
was needed to notice. That was probably right; it's very unlikely that a
file will get modified and end up with the same size and mtime as before.
But, what was not considered is that a program like NextCloud might write
two files with different content so closely together that they share the
mtime. The inode is necessary to detect that situation.

This format is designed to detect accidental appends, while having some
room for future expansion.
Detect when an unlocked file whose content is not present has gotten some
other content appended to it, and avoid treating it as a pointer file, so
that appended content will not be checked into git, but will be annexed
like any other file.
Dropped the max size of a pointer file down to 32kb, it was around 80 kb,
but without any good reason and certianly there are no valid pointer files
anywhere that are larger than 8kb, because it's just been specified what it
means for a pointer file with additional data even looks like.
I assume 32kb will be good enough for anyone. ;-) Really though, it needs
to be some smallish number, because that much of a file in git gets read
into memory when eg, catting pointer files. And since we have no use cases
for the extra lines of a pointer file yet, except possibly to add
some human-visible explanation that it is a git-annex pointer file, 32k
seems as reasonable an arbitrary number as anything. Increasing it would be
possible, eg to 64k, as long as users of such jumbo pointer files didn't
mind upgrading all their git-annex installations to one that supports the
new larger size.

File matching options like --include will be rejected in situations where
there is no filename to match against. (Or where there is a filename but
it's not relative to the cwd, or otherwise seemed too bothersome to match
against.)
The addition of listKeys' was necessary to avoid using more memory in the
common case of "git-annex info". Adding a filterM would have caused the
list to buffer in memory and not stream. This is an ugly hack, but listKeys
had previously run Annex operations inside unafeInterleaveIO (for direct
mode). And matching against a matcher should hopefully not change any Annex
state.
This does allow for eg `git-annex info somefile --include=*.ext`
although why someone would want to do that I don't really know. But it
seems to make sense to allow it.
But, consider: `git-annex info ./somefile --include=somefile`
This does not match, so will not display info about somefile.
If the user really wants to, they can `--include=./somefile`.
Using matching options like --copies or --in=remote seems likely to be
slower than git-annex find with those options, because unlike such
commands, info does not have optimised streaming through the matcher.
Note that `git-annex info remote` is not the same as
`git-annex info --in remote`. The former shows info about all files in
the remote. The latter shows local keys that are also in that remote.
The output should make that clear, but this still seems like a point
where users could get confused.

break something that expected the old output to never change. I think it's
acceptable to break that because there has never been a guarantee of
unchanging output format except with --batch for most commands. The old
output was just really weird too!
One possible wart is that "git-annex registerurl" with no options now
seems to just hang, since it's waiting for stdin input. Before, it said
"registerurl (stdin)" which was clearer about what's happenening. But this
is a deprecated mode anyway, --batch makes clear what's happening. If
anything, this problem would be a reason to eventually remove the support
for reading from stdin w/o --batch.

The "+" argument only runs the command once, so is not safe to use. Using
";" instead would have been the simplest fix, but also the slowest.
Since my phone has an xargs that supports -0, I piped find to xargs
instead. Unsure how portable this will be, perhaps some android's don't
have xargs -0 or find -printf to send null terminated output.
The business with pipefail is necessary to make a failure of find cause the
import to fail. Probably this works on all androids, but if not, it will
probably just result in a failure of find being ignored. It would be
possible to make ignorefinderror just disable setting pipefail, but then
if some android has a shell that has pipefail enabled by default, ignorefinderror
would not work, so I kept the || true approach for that.

This has tradeoffs, but is generally a win, and users who it causes git add to
slow down unacceptably for can just disable it again.
It needed to happen in an upgrade, since there are git-annex versions
that do not support it, and using such an old version with a v8
repository with filter.annex.process set will cause bad behavior.
By enabling it in v9, it's guaranteed that any git-annex version that
can use the repository does support it. Although, this is not a perfect
protection against problems, since an old git-annex version, if it's
used with a v9 repository, will cause git add to try to run
git-annex filter-process, which will fail. But at least, the user is
unlikely to have an old git-annex in path if they are using a v9
repository, since it won't work in that repository.

Do not populate the keys database with associated files,
because a bare repo has no working tree, and so it does not make sense to
populate it.
Queries of associated files in the keys database always return empty lists
in a bare repo, even if it's somehow populated. One way it could be
populated is if a user converts a non-bare repo to a bare repo.
Note that Git.Config.isBare does a string comparison, so this is not free!

Recover from corrupted content being received from a git remote due eg to a
wire error, by deleting the temporary file when it fails to verify. This
prevents a retry from failing again.
Reversion introduced in version 8.20210903, when incremental verification
was added.
Only the git remote seems to be affected, although it is certianly
possible that other remotes could later have the same issue. This only
affects things passed to getViaTmp that return (False, UnVerified) due to
verification failing. As far as getViaTmp can tell, that could just as well
mean that the transfer failed in a way that would resume, so it cannot
delete the temp file itself. Remote.Git and P2P.Annex use getViaTmp internally,
while other remotes do not, which is why only it seems affected.
A better fix perhaps would be to improve the types of the callback
passed to getViaTmp, so that some other value could be used to indicate
the state where the transfer succeeded but verification failed.

Improved support for using git-annex in a read-only repository, git-annex
branch information from remotes that cannot be merged into the git-annex
branch will now not crash it, but will be merged in memory.
To avoid this making git-annex behave one way in a read-only repository,
and another way when it can write, it's important that Annex.Branch.get
return the same thing (modulo log file compaction) in both cases.
This manages that mostly. There are some exceptions:
- When there is a transition in one of the remote git-annex branches
that has not yet been applied to the local or other git-annex branches.
Transitions are not handled.
- `git-annex log` runs git log on the git-annex branch, and so
it will not be able to show information coming from the other, not yet
merged branches.
- Annex.Branch.files only looks at files in the git-annex branch and not
unmerged branches. This affects git-annex info output.
- Annex.Branch.hs.overBranchFileContents ditto. Affects --all and
also importfeed (but importfeed cannot work in a read-only repo
anyway).
- CmdLine.Seek.seekFilteredKeys when precaching location logs.
Note use of Annex.Branch.fullname
- Database.ContentIdentifier.needsUpdateFromLog and updateFromLog
These warts make this not suitable to be merged yet.
This readonly code path is more expensive, since it has to query several
branches. The value does get cached, but still large queries will be
slower in a read-only repository when there are unmerged git-annex
branches.
When annex.merge-annex-branches=false, updateTo skips doing anything,
and so the read-only repository code does not get triggered. So a user who
is bothered by the extra work can set that.
Other writes to the repository can still result in permissions errors.
This includes the initial creation of the git-annex branch, and of course
any writes to the git-annex branch.

sync: Better error message when unable to export to a remote because
remote.name.annex-tracking-branch is configured to a ref that does not

It does not suggest how to fix the problem because there are several
possible solutions: Change the git config to point to something that does
exist, git add some files, or put files on the special remote that will be
imported and so populate the ref.
I considered just silently not doing anything, which is what it does
when annex-tracking-branch = master and nothing has been committed to
master yet. But it seems better to be explicit about it, since this is a

So that eg, addurl of several large files that take time to download will
update the index for each file, rather than deferring the index updates to
the end.
In cases like an add of many smallish files, where a new file is being
added every few seconds. In that case, the queue will still build up a
lot of changes which are flushed at once, for best performance. Since
the default queue size is 10240, often it only gets flushed once at the
end, same as before. (Notice that updateQueue updated _lastchanged
when adding a new item to the queue without flushing it; that is
necessary to avoid it flushing the queue every 5 minutes in this case.)
But, when it takes more than a 5 minutes to add a file, the overhead of
updating the index immediately is probably small, so do it after each
file. This avoids git-annex potentially taking a very very long time
indeed to stage newly added files, which can be annoying to the user who
would like to get on with doing something with the files it's already
added, eg using git mv to rename them to a better name.
This is only likely to cause a problem if it takes say, 30 seconds to
update the index; doing an extra 30 seconds of work after every 5
minute file add would be less optimal. Normally, updating the index takes
significantly less time than that. On a SSD with 100k files it takes
less than 1 second, and the index write time is bound by disk read and
write so is not too much worse on a hard drive. So I hope this will not
impact users, although if it does turn out to, the time limit could be
made configurable.
A perhaps better way to do it would be to have a background worker
thread that wakes up every 60 seconds or so and flushes the queue.
That is made somewhat difficult because the queue can contain Annex
actions and so this would add a new source of concurrency issues.
So I'm trying to avoid that approach if possible.

This reverts commit 66b2536ea0.
I misunderstood commit ac56a5c2a0
and caused a FD leak when pid locking is not used.
A LockHandle contains an action that will close the underlying lock
file, and that action is run when it is closed. In the case of a shared
lock, the lock file is opened once for each LockHandle, and only
the one for the LockHandle that is being closed will be closed.
Seem there are several races that happen when 2 threads run PidLock.tryLock
at the same time. One involves checkSaneLock of the side lock file, which may
be deleted by another process that is dropping the lock, causing checkSaneLock
to fail. And even with the deletion disabled, it can still fail, Probably due
to linkToLock failing when a second thread overwrites the lock file.
The same can happen when 2 processes do, but then one process just fails
to take the lock, which is fine. But with 2 threads, some actions where failing
even though the process as a whole had the pid lock held.
Utility.LockPool.PidLock already maintains a STM lock, and since it uses
LockShared, 2 threads can hold the pidlock at the same time, and when
the first thread drops the lock, it will remain held by the second
thread, and so the pid lock file should not get deleted until the last
thread to hold it drops the lock. Which is the right behavior, and why a
LockShared STM lock is used in the first place.
The problem is that each time it takes the STM lock, it then also calls
PidLock.tryLock. So that was getting called repeatedly and concurrently.
Fixed by noticing when the shared lock is already held, and stop calling
PidLock.tryLock again, just use the pid lock that already exists then.
Also, LockFile.PidLock.tryLock was deleting the pid lock when it failed
to take the lock, which was entirely wrong. It should only drop the side
lock.

This fixes a reversion introduced in commit

I didn't notice there that it was handling the case of a shared lock

This version of git -- or its new default "ort" resolver -- handles such
a conflict by staging two files, one with the original name and the other
named file~ref. Use unmergedSiblingFile when the latter is detected.
(It doesn't do that when the conflict is between a directory and a file
or symlink though, so see previous commit for how that case is handled.)
The sibling file has to be deleted separately, because cleanConflictCruft
may not delete it -- that only handles files that are annex links,
but the sibling file may be the non-annexed file side of the conflict.
The graftin code had assumed that, when the other side of a conclict
is a symlink, the file in the work tree will contain the non-annexed
content that we want it to contain. But that is not the case with the new
git; the file may be the annex link and needs to be replaced with the
content, while the annex link will be written as a -variant file.
(The weird doesDirectoryExist check in graftin turns out to still be
needed, test suite failed when I tried to remove it.)
Test suite passes with new git with ort resolver default. Have not tried it
with old git or other defaults.

This bug mostly would happen when the downloads ran very fast or were
all failing (how I reproduced it), because there have to be two
downloads that finish very close to the same time to trigger the race.
So most users of -J probably would not see much impact from the bug.
Bugfix: When -J was enabled, getting files leaked a ever-growing number of
git cat-file processes.
(Since commit dd39e9e255)
The leak happened when mergeState called stopNonConcurrentSafeCoProcesses.
While stopNonConcurrentSafeCoProcesses usually manages to stop everything,
there was a race condition where cat-file processes were leaked. Because
catFileStop modifies Annex.catfilehandles in a non-concurrency safe way,
and could clobber modifications made in between. Which should have been ok,
since originally catFileStop was only used at shutdown.
Note the comment on catFileStop saying it should only be used when nothing
else is using the handles. It would be possible to make catFileStop
race-safe, but it should just not be used in a situation where a race is
possible. So I didn't bother.
Instead, the fix is just not to stop any processes in mergeState. Because
in order for mergeState to be called, dupState must have been run, and it
enables concurrency mode, stops any non-concurrent processes, and so all
processes that are running are concurrency safea. So there is no need to
stop them when merging state. Indeed, stopping them would be extra work,
even if there was not this bug.

See comment for analysis.
At first I thought I'd need to convert all T.unpack in git-annex, but
luckily not -- so long as the Text is read from a file, the filesystem
encoding is applied and T.unpack is fine. It's only when using Feed
that the filesystem encoding is not applied.
While this fixes the crash, it does result in some mojibake, eg:

While intended for converting URL keys added by addurl --fast to be
as if added by addurl --relaxed, it can also be used to remove size
from other types of keys. Although that is not likely to be useful
for checksummed keys, I suppose it could be used for WORM or other
non-checksum keys.
Specifying the --remove-size option does not prevent other migrations
from taking effect if there's a key upgrade to perform, or if the
backend has changed. So --backend=URL needs to be used to prevent
migrating an URL key to the default backend.
Note that it's not possible to use git-annex migrate to convert from a
non-URL key to an URL key, as URL keys cannot be generated, except by
addurl. So while this can get the same effect as --relaxed would have
when addurl --fast was used, when --fast was not used, it won't work, or
if --backend=URL is not used will remove the size but not prevent
checksum verification, which is not useful. Due to this complexity, I
decided not to mention it in the git-annex addurl man page.

metadata --batch --json: Reject input whose "fields" does not consist of
arrays of strings. Such invalid input used to be silently ignored.
Used to be that parseJSON for a JSONActionItem ran parseJSON separately
for the itemAdded, and if that failed, did not propagate the error. That
allowed different items with differently named fields to be parsed.
But it was actually only used to parse "fields" for metadata, so that
flexability is not needed.
The fix is just to parse "fields" as-is. AddJSONActionItemFields is needed
only because of the wonky way Command.MetaData adds onto the started json
object.
Note that this line got a dummy type signature added,
just because the type checker needs it to be some type.
itemFields = Nothing :: Maybe Bool
Since it's Nothing, it doesn't really matter what type it is,
and the value gets turned into json and is then thrown away.

Turns out that CommandStart actions do not have their exceptions caught,
which is why the giveup was causing a crash. Mostly these actions
do not do very much work on their own, but it does seem possible there
are other commands whose CommandStart also throws an exception.
So, my first attempt at a fix was to catch those exceptions. But,
--json-error-messages then causes a difficulty, because in order to output
a json error message, an action needs to have been started; that sets up
the json object that the error message will be included in a field of.
While it would be possible to output an object with just an error field,
this would be json output of a format that the user has no reason to
expect, that happens only in an exceptional circumstance. That is something
I have always wanted to avoid with the json output; while git-annex man
pages don't document what the json looks like, the output has always
been made to be self-describing. Eg, it includes "error-messages":[]
even when there's no errors.
With that ruled out, it doesn't seem a good idea to catch CommandStart
exceptions and display the error to stderr when --json-error-messages
is set. And so I don't know if it makes sense to catch exceptions from that
at all. Maybe I'd have a different opinion if --json-error-messages did not
exist though.
So instead, output a blank line like other batch commands do.
This also leaves open the possibility of implementing support for matching
object with metadata --json, which would also want to output a blank line
when the input didn't match.

This removes a messy caveat that was easy to forget and caused at least one
bug. The price paid is that, after a write to a MultiWriter db, it has to
close the db connection that it had been using to read, and open a new
connection. So it might be a little bit slower. But, writes are usually
batched together, so there's often only a single write, and so there should
not be much of a slowdown. Notice that SingleWriter already closed the db
connection after a write, so paid the same overhead.
This is the second try at fixing a bug: git-annex get when run as the first

git does not crash when there's a remote configured for a user who does
not exist, and this prevents git-annex from crashing too. Consider that
a user might exist on one system but not another, and the git repo be
moved between systems. So not crashing is desirable.
Note that git fetch seems to mishandle a remote path like ~foo/bar
when the user does not exist. While it does access ./~foo/bar,
and gets as far as running git-upload-pack on the path,
it then complains there is no such repo. So different parts of git seem
to be doing different things in that edge case. Anyway, git-annex does
not need to be bug-for-bug compatible with git.

test: Put gpg temp home directory in system temp directory, not filesystem
being tested.
Since I've found indications gpg can fail talking to the agent when the
socket ends up on eg, fat. And to hopefully fix this bug report I've
followed up on.
The main risk in using the system temp dir is that TMPDIR could be set to a
long directory path, which is too long to put a unix socket in. To
partially amelorate that risk, it uses either an absolute or a relative
path, whichever is shorter. (Hopefully gpg will not convert it to a longer
form of the path..)
If the user sets TMPDIR to something so long a path to it +
"S.gpg-agent" is too long, I suppose that's their issue to deal with.

This negotiation is not supported by versions of git-annex older
than 6.20180312. Well, maybe really 6.20180227 or so, but using that in
the changelog simplifies things since it was the version for the other
changes as well.
See commit c81768d425 for the back story.
As well as allowing for future protocol improvements, this will result
in negoatiating protocol version 1, which is an improvement over default
version 0.
In fact, it looks like no supported version of git-annex will use
protocol version 0, since version 1 was introduced in 6.20180227.
Still, removing the code for version 0 seems unncessary.

* git-annex-shell: Removed several commands that were only needed to
support git-annex versions older than 6.20180312.
(lockcontent, recvkey, sendkey, transferinfo, commit)
The P2P protocol was added in that version, and used ever since, so
this code was only needed for interop with older versions.
"git-annex-shell commit" is used by newer git-annex versions, though
unnecessarily so, because the p2pstdio command makes a single commit at
shutdown. Luckily, it was run with stderr and stdout sent to /dev/null,
and non-zero exit status or other exceptions are caught and ignored. So,
that was able to be removed from git-annex-shell too.
git-annex-shell inannex, recvkey, sendkey, and dropkey are still used by
gcrypt special remotes accessed over ssh, so those had to be kept.
It would probably be possible to convert that to using the P2P protocol,
but it would be another multi-year transition.
Some git-annex-shell fields were able to be removed. I hoped to remove
all of them, and the very concept of them, but unfortunately autoinit
is used by git-annex sync, and gcrypt uses remoteuuid.
The main win here is really in Remote.Git, removing piles of hairy fallback
code.

This improves the borg special remote memory usage, by
letting it only load one archive's worth of filenames into memory at a
time, and building up a larger tree out of the chunks.
When a borg repository has many archives, git-annex could easily OOM
before. Now, it will use only memory proportional to the number of
annexed keys in an archive.
Minor implementation wart: Each new chunk re-opens the content
identifier database, and also a new vector clock is used for each chunk.
This is a minor innefficiency only; the use of continuations makes
it hard to avoid, although putting the database handle into a Reader
monad would be one way to fix it.
It may later be possible to extend the ImportableContentsChunkable
interface to remotes that are not third-party populated. However, that
would perhaps need an interface that does not use continuations.
The ImportableContentsChunkable interface currently does not allow
populating the top of the tree with anything other than subtrees. It
would be easy to extend it to allow putting files in that tree, but borg
doesn't need that so I left it out for now.

would return eg "../../foo", resulting in fileRef returning
":./../../foo", which will make git cat-file crash since that's
not a valid path in the repo.
Fix is simply to make fileRef detect paths outside the repo and return
Nothing. Then catKey can be skipped. This needed several bugfixes to
dirContains as well, in previous commits.
In Command.Smudge, this led to needing to check for Nothing. That case
should actually never happen, because the fileoutsiderepo check will
detect it earlier.

sync --content: Avoid a redundant checksum of a file that was
incrementally verified, when used on NTFS and perhaps other filesystems.
When sync has just gotten the content, it does not need to check inAnnex a
second time. On NTFS, for some reason the write of the inode cache after
it gets the content is not immediately able to be read, and with an
empty/non-matching inode cache due to that stale data, inAnnex falls back
to hashing the whole object to determine if it's present.

This method avoids breaking test_readonly. Just check if the dest file
exists, and avoid CoW probing when it does, so when CoW probing fails,
it can resume where the previous non-CoW copy left off.
If CoW has been probed already to work, delete the dest file
since a CoW copy will presumably work. It seems like it would be almost
as good to just skip CoW copying in this case too, but consider that the
dest file might have started to be copied from some other remote, not
using CoW, but CoW has been probed to work to copy from the current
place.

commit 63d508e885 broke test_readonly.
When a local git remote is readonly, tryCopyCoW run to copy a file
from it failed at withOtherTmp.

Disabling git-annex branch update for this command is
ok, because it does not use any information from the branch,
but only logs the location when it adds a key.
