Taking a ShortByteString and using OverloadedStrings should avoid it
being converted from a String.
The reason there is no IsString instance for OsPath is presumably the
bad behavior of IsString for ByteString on unicode btw. But
literalOsPath won't be used with unicode in git-annex.

This removes that function, using file-io readFile' instead.
Had to deal with newline conversion, which readFileStrict does on
Windows. In a few cases, that was pretty ugly to deal with.

And follow-on changes.
Note that relatedTemplate was changed to operate on a RawFilePath, and
so when it counts the length, it is now the number of bytes, not the
number of code points. This will just make it truncate shorter strings
in some cases, the truncation is still unicode aware.
When not building with the OsPath flag, toOsPath . fromRawFilePath and
fromRawFilePath . fromOsPath do extra conversions back and forth between
String and ByteString. That overhead could be avoided, but that's the
non-optimised build mode, so didn't bother.

By using System.Directory.OsPath, which takes and returns OsString,
which is a ShortByteString. So, things like dirContents currently have the
overhead of copying that to a ByteString, but that should be less than
the overhead of using Strings which often in turn were converted to
RawFilePaths.
Added Utility.OsString and the OsString build flag. That flag is turned
on in the stack.yaml, and will be turned on automatically by cabal when
built with new enough libraries. The stack.yaml change is a bit ugly,
and that could be reverted for now if it causes any problems.
Note that Utility.OsString.toOsString on windows is avoiding only a
check of encoding that is documented as being unlikely to fail. I don't
think it can fail in git-annex; if it could, git-annex didn't contain
such an encoding check before, so at worst that should be a wash.
Assistant and smudge also updated.
This does add a small amount of extra work, getting the TopFilePath.
Not enough to be concerned by.
Also improve documentation to make clear that files inside dotdirs are
treated as dotfiles.

Each command that first checks preferred content (and/or required
content) and then does something that can change the sizes of
repositories needs to call prepareLiveUpdate, and plumb it through the
preferred content check and the location log update.
So far, only Command.Drop is done. Many other commands that don't need
to do this have been updated to keep working.
There may be some calls to NoLiveUpdate in places where that should be
done. All will need to be double checked.
Not currently in a compilable state.
This was caused by commit fb8ab2469d putting
an isPointerFile check in the wrong place. So if the file was not a pointer
file at that point, but got replaced by one before the file got locked
down, the pointer file would be ingested into the annex.
The fix is simply to move the isPointerFile check to after safeToAdd locks
down the file. Now if the file changes to a pointer file after the
isPointerFile check, ingestion will see that it changed after lockdown,
and will refuse to add it to the annex.

This is to avoid inserting a cluster uuid into the location log when
only dead nodes in the cluster contain the content of a key.
One reason why this is necessary is Remote.keyLocations, which excludes
dead repositories from the list. But there are probably many more.
Implementing this was challenging, because Logs.Location importing
Logs.Cluster which imports Logs.Trust which imports Remote.List resulted
in an import cycle through several other modules.
Resorted to making Logs.Location not import Logs.Cluster, and instead
it assumes that Annex.clusters gets populated when necessary before it's
called.
That's done in Annex.Startup, which is run by the git-annex command
(but not other commands) at early startup in initialized repos. Or,
is run after initialization.
Note that is Remote.Git, it is unable to import Annex.Startup, because
Remote.Git importing Logs.Cluster leads the the same import cycle.
So ensureInitialized is not passed annexStartup in there.
Other commands, like git-annex-shell currently don't run annexStartup
either.
So there are cases where Logs.Location will not see clusters. So it won't add
any cluster UUIDs when loading the log. That's ok, the only reason to do
that is to make display of where objects are located include clusters,
and to make commands like git-annex get --from treat keys as being located
in a cluster. git-annex-shell certainly does not do anything like that,
and I'm pretty sure Remote.Git (and callers to Remote.Git.onLocalRepo)
don't either.
When imported along with Logs.Location, it can be an unused import and
it won't warn, due to reexports. The point if this is really to show
that Logs.Presence is not widely used, outside Logs/
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.
While redundant concurrent transfers were already prevented in most
cases, it failed to prevent the case where two different repositories were
sending the same content to the same repository. By removing the uuid
from the transfer lock file for Download transfers, one repository
sending content will block the other one from also sending the same
content.
In order to interoperate with old git-annex, the old lock file is still
locked, as well as locking the new one. That added a lot of extra code
and work, and the plan is to eventually stop locking the old lock file,
at some point in time when an old git-annex process is unlikely to be
running at the same time.
Note that in the case of 2 repositories both doing eg
`git-annex copy foo --to origin`
the output is not that great:
copy b (to origin...)
transfer already in progress, or unable to take transfer lock
git-annex: transfer already in progress, or unable to take transfer lock
97% 966.81 MiB 534 GiB/s 0sp2pstdio: 1 failed
Lost connection (fd:14: hPutBuf: resource vanished (Broken pipe))
Transfer failed
Perhaps that output could be cleaned up? Anyway, it's a lot better than letting
the redundant transfer happen and then failing with an obscure error about
a temp file, which is what it did before. And it seems users don't often
try to do this, since nobody ever reported this bug to me before.
(The "97%" there is actually how far along the *other* transfer is.)

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.

It's trivial enough that it it's not worth factoring it out to somewhere

The getSocket comment that mentioned using ":port"

This aims to future-proof gpg key generation. OpenPGP is in flux with a
conflict over standards ongoing. It seems not unlikely that different
systems will have different gpg commands that support different algorithms.
This also simplifies the code by using the --quick-gen-key interface rather
than the experimental batch interface. It seems less likely that
--quick-gen-key will break than an experimental interface (whose
documentation I can no longer find).
--quick-gen-key is supported since gpg 2.1.0 (2014).

Make git-annex get/copy/move --from foo override configuration of
remote.foo.annex-ignore, as documented.
This already worked for remotes supporting hasKeyCheap. For others though,
git-annex copy --from foo would silently not do anything, while
git-annex copy --to foo would use the annex-ignored remote.
Also improved the annex-ignore docs, to reflect that `git-annex get`
without --from will skip using annex-ignored remotes, for example.

Minor optimisation, but a win in every case, except for a couple where
it's a wash.
Note that replaceFile still takes a FilePath, because it needs to
operate on Chars to truncate unicode filenames properly.
Note that the use of s2w8 in genUUIDInNameSpace made it truncate unicode
characters. Luckily, genUUIDInNameSpace is only ever used on ASCII
strings as far as I can determine. In particular, git-remote-gcrypt's
gcrypt-id is an ASCII string.
Every remote that sets localpath also implements an availability that
reutrns Unavailable when a local directory is not available.
This makes external remotes, and others that get support for
availability Unavailable to be used by checkAvailable. (Which is only
used by the assistant.)
Had to keep localpath though, since other parts of the assistant use it
to eg, sync with a remote when a removable drive is plugged in.

This is groundwork for making special remotes like borg be skipped by
sync when on an offline drive.
Added AVAILABILITY UNAVAILABLE reponse and the UNAVAILABLERESPONSE extension
to the external special remote protocol. The extension is needed because
old git-annex, if it sees that response, will display a warning
message. (It does continue as if the remote is globally available, which
is acceptable, and the warning is only displayed at initremote due to
remote.name.annex-availability caching, but still it seemed best to make
this a protocol extension.)
The remote.name.annex-availability git config is no longer used any
more, and is documented as such. It was only used by external special
remotes to cache the availability, to avoid needing to start the
external process every time. Now that availability is queried as an
Annex action, the external is only started by sync (and the assistant),
when they actually check availability.

Fix behavior when importing a tree from a directory remote when the
directory does not exist. An empty tree was imported, rather than the
import failing. Merging that tree would delete every file in the
branch, if those files had been exported to the directory before.
The problem was that dirContentsRecursive returned [] when the directory
did not exist. Better for it to throw an exception. But in commit
74f0d67aa3 back in 2012, I made it never
theow exceptions, because exceptions throw inside unsafeInterleaveIO become
untrappable when the list is being traversed.
So, changed it to list the contents of the directory before entering
unsafeInterleaveIO. So exceptions are thrown for the directory. But still
not if it's unable to list the contents of a subdirectory. That's less of a
problem, because the subdirectory does exist (or if not, it got removed
after being listed, and it's ok to not include it in the list). A
subdirectory that has permissions that don't allow listing it will have its
contents omitted from the list still.
(Might be better to have it return a type that includes indications of
errors listing contents of subdirectories?)
The rest of the changes are making callers of dirContentsRecursive
use emptyWhenDoesNotExist when they relied on the behavior of it not
throwing an exception when the directory does not exist. Note that
it's possible some callers of dirContentsRecursive that used to ignore
permissions problems listing a directory will now start throwing exceptions
on them.
The fix to the directory special remote consisted of not making its
call in listImportableContentsM use emptyWhenDoesNotExist. So it will
throw an exception as desired.

This causes changes to the original branch to get merged with a single
sync. Before, it took 2 syncs; the first happened to update the synced/
branch, and the second merged changes from the synced/ branch into the
ajusted branch.
Using mergeToAdjustedBranch when tomerge == origbranch is probably
overkill, but it does work fine.

git add will fail if the file got deleted in the meantime. And since it was
queued, there was a window until the queue flushed where a deletion of the
file would cause a crash.
Instead, reuse Command.Add.addFile, which sha1 hashes the file itself
immediately, and then queues the index update. Ignore exceptions that will
happen if the file got deleted already.
