git-annex assist
assist: New command, which is the same as git-annex sync but with
new files added and content transferred by default.

(Also this fixes another reversion in git-annex sync,
--commit --no-commit, and --message were not enabled, oops.)

See added comment for why git-annex assist does commit staged
changes elsewhere in the work tree, but only adds files under
the cwd.

Note that it does not support --no-commit, --no-push, --no-pull
like sync does. My thinking is, why should it? If you want that
level of control, use git commit, git annex push, git annex pull.
Sync only got those options because pull and push were not split
out.

json object for FileNotFound
When a nonexistant file is passed to a command and  --json-error-messages
is enabled, output a JSON object indicating the problem.

(But git ls-files --error-unmatch still displays errors about such files in
some situations.)

I don't like the duplication of the name of the command introduced by this,
but I can't see a great way around it. One way would be to pass the Command
instead.

When json is not enabled, the stderr is unchanged. This is necessary
because some commands like find have custom output. So dislaying
"find foo not found" would be wrong. So had to complicate things with
toplevelFileProblem having different output with and without json.

When not using --json-error-messages but still using --json, it displays
the error to stderr, but does display a json object without the error. It
does have an errorid though. Unsure how useful that behavior is.

filter out control characters in warning messages
Converted warning and similar to use StringContainingQuotedPath. Most
warnings are static strings, some do refer to filepaths that need to be
quoted, and others don't need quoting.

Note that, since quote filters out control characters of even
UnquotedString, this makes all warnings safe, even when an attacker
sneaks in a control character in some other way.

When json is being output, no quoting is done, since json gets its own
quoting.

This does, as a side effect, make warning messages in json output not
be indented. The indentation is only needed to offset warning messages
underneath the display of the file they apply to, so that's ok.

git style filename quoting for giveup
When the filenames are part of the git repository or other files that
might have attacker-controlled names, quote them in error messages.

This is fairly complete, although I didn't do the one in
Utility.DirWatcher.INotify.hs because that doesn't have access to
Git.Filename or Annex.

But it's also quite possible I missed some. And also while scanning for
these, I found giveup used with other things that could be attacker
controlled to contain control characters (eg Keys). So, I'm thinking
it would also be good for giveup to just filter out control characters.
This commit is then not the only line of defence, but just good
formatting when git-annex displays a filename in an error message.

Windows: Support long filenames in more (possibly all) of the code
Works around this bug in unix-compat:
https://github.com/jacobstanley/unix-compat/issues/56
getFileStatus and other FilePath using functions in unix-compat do not do
UNC conversion on Windows.

Made Utility.RawFilePath use convertToWindowsNativeNamespace to do the
necessary conversion on windows to support long filenames.

Audited all imports of System.PosixCompat.Files to make sure that no
functions that operate on FilePath were imported from it. Instead, use
the equvilants from Utility.RawFilePath. In particular the
re-export of that module in Common had to be removed, which led to lots
of other changes throughout the code.

The changes to Build.Configure, Build.DesktopFile, and Build.TestConfig
make Utility.Directory not be needed to build setup. And so let it use
Utility.RawFilePath, which depends on unix, which cannot be in
setup-depends.

remove --backend from global options
--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.

fix overwrite race with small file that got large
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.

is not already added, and while it's processing it, the annex symlink is
overwritten with something else, avoid git-annex overwriting that with
the symlink again.

fix add overwrite race with git-annex add to annex
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 reversion
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.

bwlimit
Added annex.bwlimit and remote.name.annex-bwlimit config that works for git
remotes and many but not all special remotes.

This nearly works, at least for a git remote on the same disk. With it set
to 100kb/1s, the meter displays an actual bandwidth of 128 kb/s, with
occasional spikes to 160 kb/s. So it needs to delay just a bit longer...
I'm unsure why.

However, at the beginning a lot of data flows before it determines the
right bandwidth limit. A granularity of less than 1s would probably improve
that.

And, I don't know yet if it makes sense to have it be 100ks/1s rather than
100kb/s. Is there a situation where the user would want a larger
granularity? Does granulatity need to be configurable at all? I only used that
format for the config really in order to reuse an existing parser.

This can't support for external special remotes, or for ones that
themselves shell out to an external command. (Well, it could, but it
would involve pausing and resuming the child process tree, which seems
very hard to implement and very strange besides.) There could also be some
built-in special remotes that it still doesn't work for, due to them not
having a progress meter whose displays blocks the bandwidth using thread.
But I don't think there are actually any that run a separate thread for
downloads than the thread that displays the progress meter.

smudge: check for known annexed inodes before checking annex.largefiles
smudge: Fix a case where an unlocked annexed file that annex.largefiles
does not match could get its unchanged content checked into git, due to git
running the smudge filter unecessarily.

When the file has the same inodecache as an already annexed file,
we can assume that the user is not intending to change how it's stored in
git.

Note that checkunchangedgitfile already handled the inverse case, where the
file was added to git previously. That goes further and actually sha1
hashes the new file and checks if it's the same hash in the index.

It would be possible to generate a key for the file and see if it's the
same as the old key, however that could be considerably more expensive than
sha1 of a small file is, and it is not necessary for the case I have, at
least, where the file is not modified or touched, and so its inode will
match the cache.

git-annex add was changed, when adding a small file, to remove the inode
cache for it. This is necessary to keep the recipe in
doc/tips/largefiles.mdwn for converting from annex to git working.
It also avoids bugs/case_where_using_pathspec_with_git-commit_leaves_s.mdwn
which the earlier try at this change introduced.

add, addurl, importfeed, import: Added --no-check-gitignore option

(--force is used for too many different things, and at least one
of these also uses it for something else. I would like to reduce
--force's footprint until it only forces drops or a few other data
losses. For now, --force still disables checking ignores too.)

addunused: Don't check .gitignores when adding files. This is a behavior
change, but I justify it by analogy with git add of a gitignored file
adding it, asking to add all unused files back should add them all back,
not skip some. The old behavior was surprising.

In Command.Lock and Command.ReKey, CheckGitIgnore False does not change
behavior, it only makes explicit what is done. Since these commands are run
on annexed files, the file is already checked into git, so git add won't
check ignores.

add SeekInput (not yet used)
No behavior changes (hopefully), just adding SeekInput and plumbing it
through to the JSON display code for later use.

Over the course of 2 grueling days.

withFilesNotInGit reimplemented in terms of seekHelper
should be the only possible behavior change. It seems to test as
behaving the same.

Note that seekHelper dummies up the SeekInput in the case where
segmentPaths' gives up on sorting the expanded paths because there are
too many input paths. When SeekInput later gets exposed as a json field,
that will result in it being a little bit wrong in the case where
100 or more paths are passed to a git-annex command. I think this is a
subtle enough problem to not matter. If it does turn out to be a
problem, fixing it would require splitting up the input
parameters into groups of < 100, which would make git ls-files run
perhaps more than is necessary. May want to revisit this, because that
fix seems fairly low-impact.

add --force-small: Send all non-regular files through addFile
Running `git annex add --force-small` on a modified submodule fails
when the submodule path is fed to hash-object.  This failure is
unlikely to be triggered by a caller passing a submodule explicitly to
`git annex add` because there's nothing useful that annex-add can do
with a submodule.  A more likely scenario for hitting this failure is
that the caller passes "." or a subdirectory to `annex-add` while a
submodule underneath the specified path happens to be modified.

addSmallOverridden already routes symbolic links through addFile
rather than using the custom hash-object/update-index call.  The
latter is valid only for regular files, so extend this condition so
that everything that isn't a regular file goes through addFile.  Doing
so avoids the above error because submodules come in as directories.

add --force-annex/--force-git
options make it easier to override annex.largefiles configuration
(and potentially safer as it avoids bugs like the smudge bug fixed
in the last release)

Deleted some old comments that were posted to the man page discussing such
options.

Updated docs that used -c annex.largefiles to use the options.

Note that addSmallOverridden was needed to avoid the clean filter running
on the file. It would be possible to make addFile also update the index
directly, rather than going via git add. However, it was not necessary,
and I want to avoid breaking on some edge case, particularly if the code in
addSmallOverridden has some oversight.

Also, when annex.addunlocked is set and annex.largefiles does not match a file,
git annex add --force-large works, but git status will then show the file
as added, with a unstaged modification. The unstaged modification adds the
file to git. This is identical behavior to using -c annex.largefiles=nothing
when annex.addunlocked is set. This does not prevent committing what was
intended to be added. I have not gotten to the bottom of why git thinks
the file is modified and runs it through the clean filter in this case.

annex.dotfiles
The git add behavior changes could be avoided if it turns out to be
really annoying, but then it would need to behave the old way when
annex.dotfiles=false and the new way when annex.dotfiles=true. I'd
rather not have the config option result in such divergent behavior as
`git annex add .` skipping a dotfile (old) vs adding to annex (new).

Note that the assistant always adds dotfiles to the annex.
This is surprising, but not new behavior. Might be worth making it also
honor annex.dotfiles, but I wonder if perhaps some user somewhere uses
it and keeps large files in a directory that happens to begin with a
dot. Since dotfiles and dotdirs are a unix culture thing, and the
assistant users may not be part of that culture, it seems best to keep
its current behavior for now.

annex.addunlocked expressions
* annex.addunlocked can be set to an expression with the same format used by
  annex.largefiles, in case you want to default to unlocking some files but
  not others.
* annex.addunlocked can be configured by git-annex config.

Added a git-annex-matching-expression man page, broken out from
tips/largefiles.

A tricky consequence of this is that git-annex add --relaxed
honors annex.addunlocked, but an expression might want to know the size
or content of an url, which it's not going to download. I decided it was
better not to fail, and just dummy up some plausible data in that case.

Performance impact should be negligible. The global config is already
loaded for annex.largefiles. The expression only has to be parsed once,
and in the simple true/false case, it should not do any additional work
matching it.
