Fix a reversion that prevented --batch commands (and the assistant)
from noticing data written to the journal by other commands.
I have not identified which commit broke this for sure,
but probably it was aeca7c2207
--batch commands that wrote to the journal avoided the problem since
journalIgnorable sets unset on write. It's a little bit surprising that
nobody noticed that query --batch commands did not see data written by
other commands.

It does not make sense for either; importing from an existing bucket should
not write to it. And the user may not have write access at all. And exporting to
a bucket should not write other files.
Also this prevents the uuid file being imported after being written.

This caused git to complain that filter-process failed and kill it with
signal 15. Because it wrote an extra flushPkt for an empty file, which
git did not expect, and so git saw an unexpected response to the next
request.
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
files. So this isn't a crippling bug.

--backend is no longer a global option, and is only accepted by commands
that actually need it.
Three commands that used to support backend but don't any longer are
watch, webapp, and assistant. It would be possible to make them support it,
but I doubt anyone used the option with these. And in the case of webapp
and assistant, the option was handled inconsistently, only taking affect
when the command is run with an existing git-annex repo, not when it
creates a new one.
Also, renamed GlobalOption etc to AnnexOption. Because there are many
options of this type that are not actually global (any more) and get
added to commands that need them.

When adding a small file, it does not get locked down, so can be modified
after git-annex checks that it's small. The use of queued git add made the
race window nice and wide too.
Fixed by checking if the file has changed, and by not using git add.
Instead, have to recapitulate git add's handling of things like symlinks
and executable files.

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.

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.

Fix retrival of an empty file that is stored in a special remote with
chunking enabled.
The speculative chunk stuff caused a reversion by adding an empty list for
the empty file. Which is just wrong; the empty file is still stored on the
remote, and should be retrieved like any other file. It uses 1 chunk, so
`max 1` is the simple fix.

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.

Use cases include using git-annex init --no-autoenable and then going back
and enabling the special remotes that have autoenable configured. As well
as just querying to remember which ones have it enabled.
It lists all special remotes that have autoenable=yes whether currently
enabled or not. And it can be used with --json.
I pondered making this "git-annex info autoenable", but that seemed wrong
because then if the use has a directory named "autoenable", it's unclear
what they are asking for. (Although "git-annex info remote" may be
similarly unclear.) Making it an option does mean that it can't be provided
via --batch though.

test: When limiting tests to run with -p, work around tasty limitation by
automatically including dependent tests.
This fixes a reversion because it didn't used to use dependencies and
forced tasty to run the init tests first. That changed when parallelizing
the test suite.
It will sometimes do a little more work than strictly required,
because it adds init tests deps when limited to eg quickcheck tests,
which don't depend on them. But this only adds a few seconds work.

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 purpose of this is to fix situations where the annex object file is
stored in a directory structure other than where annex symlinks point to.
But it will also move object files from the hashdirmixed back to
hashdirlower if the repo configuration makes that the normal location.
It would have been more work to avoid that than to let it do it.

Added support for "megabit" and related bandwidth units in
annex.stalldetection and everywhere else that git-annex parses data units.
Note that the short form is "Mbit" not "Mb" because that differs from "MB"
only in case, and git-annex parses units case-insensitively. It would be
horrible if two different versions of git-annex parsed the same value
differently, so I don't think "Mb" can be supported.

Avoid treating refs/annex/last-index or other refs that are not commit
objects as evidence of repository corruption.
The repair code checks to find bad refs by trying to run `git log` on
them, and assumes that no output means something is broken. But git log
on a tree object is empty.
This was worth fixing generally, not as a special case, since it's certainly
possible that other things store tree or other objects in refs.

rsync 3.2.4 broke backwards-compatability by preventing exposing filenames
to the shell. Made the rsync and gcrypt special remotes detect this and
disable shellescape.
An alternative fix would have been to always set RSYNC_OLD_ARGS=1.
Which would avoid the overhead of probing rsync --help for each affected
remote. But that is really very fast to run, and it seemed better to switch
to the modern code path rather than keeping on using the bad old code path.

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.

add: Avoid unncessarily converting a newly unlocked file to be stored
in git when it is not modified, even when annex.largefiles does not
match it.
This fixes a reversion in version 10.20220222, where git-annex unlock
followed by git-annex add, followed by git commit file could result in
git thinking the file was modified after the commit.
I do have half a mind to remove the withUnmodifiedUnlockedPointers part
of git-annex add. It seems weird, despite that old bug report arguing
a case of consistency that it ought to behave that way. When git-annex
add surpises me, it seems likely it's wrong.. But for now, this is the
smallest possible fix.

Directory special remotes with importtree=yes have changed to once more
take inodes into account. This will cause extra work when importing from a
directory on a FAT filesystem that changes inodes on every mount.
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.

It may not really be necessary to add to PATH the directory where the
