refactor getCurrentBranch
Both Command.Sync and Annex.Ingest had their own versions of this.

The one in Annex.Ingest used Git.Branch.currentUnsafe, but does not seem
to need it. That is only checking to see if it's in an adjusted unlocked
branch, and when in an adjusted branch, the branch does in fact exist,
so the added check that Git.Branch.current does is fine.

adjust --hide-missing
* At long last there's a way to hide annexed files whose content
  is missing from the working tree: git-annex adjust --hide-missing
* When already in an adjusted branch, running git-annex adjust
  again will update the branch as needed. This is mostly
  useful with --hide-missing to hide/unhide files after their content
  has been dropped or received.

Still needs integration with sync and the assistant, and not as fast as it
could be, but already usable.

improve types to allow combining some adjustments
Combinations like --hide-misssing --unlocked seem very useful. On the
other hand, combining --fix with --unlock doesn't make sense because a
file can be either unlocked or a symlink that can be fixed, but not
both.

Changed the serialization of HideMissingAdjustment in passing, but it
has not actually been used yet so nothing will be broken.

fix rekey/migrate bookkeeping in v6
After 220317df5a the test suite still
detected a problem; migrate of an unlocked file replaced it with a
pointer file rather than a file with the content.

This was a bookeeping problem; the worktree file was being copied to the object
file and the inode cache updated, but if that database write didn't get
flushed in time, later checks would think the content was not present.
Fixed by copying the object file to the worktree file instead, which
avoids needing to update the inode cache.

Also, only copy when there's a hard link to break, not always.

v6: fix migrate of unlocked file
After commit b2bafdb2fc the test suite
threw up a failure migrating unlocked files.

I'm not clear how that commit broke it (presumably by inAnnex reporting
the right information now), but the actual problem is plain:
The inodecache for the worktree file is generated, but then the file is
replaced with a copy (unncessarily unless annex.link is set, but the
code always does so) and so linkToAnnex/linkAnnex then fails because it
notices the inode cache is not valid.

removed the old Android app
Running git-annex linux builds in termux seems to work well enough that the
only reason to keep the Android app would be to support Android 4-5, which
the old Android app supported, and which I don't know if the termux method
works on (although I see no reason why it would not).
According to [1], Android 4-5 remains on around 29% of devices, down from
51% one year ago.

[1] https://www.statista.com/statistics/271774/share-of-android-platforms-on-mobile-devices-with-android-os/

This is a rather large commit, but mostly very straightfoward removal of
android ifdefs and patches and associated cruft.

Also, removed support for building with very old ghc < 8.0.1, and with
yesod < 1.4.3, and without concurrent-output, which were only being used
by the cross build.

Some documentation specific to the Android app (screenshots etc) needs
to be updated still.

clean up url removal presence update
* rmurl: Fix a case where removing the last url left git-annex thinking
  content was still present in the web special remote.
* SETURLPRESENT, SETURIPRESENT, SETURLMISSING, and SETURIMISSING
  used to update the presence information of the external special remote
  that called them; this was not documented behavior and is no longer done.

Done by making setUrlPresent and setUrlMissing only update presence info
for the web, and only when the url is a web url. See the comment for
reasoning about why that's the right thing to do.

In AddUrl, had to make it update location tracking, to handle the
non-web-url case.

sync: Warn when a remote's export is not updated to the current tree because export tracking is not configured.
Only display the warning when the current branch has a tree that is not
the same as the tree in the export.

Note that it doesn't check to see if the current tree is
in incompleteExportedTreeish; it might be worth checking that and reminding
the user about an incomplete export, but when export tracking is not
configured, they are probably not in the right clone of the repository to
resolve the incomplete export.

added -z
Added -z option to git-annex commands that use --batch, useful for
supporting filenames containing newlines.

It only controls input to --batch, the output will still be line delimited
unless --json or etc is used to get some other output. While git often
makes -z affect both input and output, I don't like trying them together,
and making it affect output would have been a significant complication,
and also git-annex output is generally not intended to be machine parsed,
unless using --json or a format option.

Commands that take pairs like "file key" still separate them with a space
in --batch mode. All such commands take care to support filenames with
spaces when parsing that, so there was no need to change it, and it would
have needed significant changes to the batch machinery to separate tose
with a null.

To make fromkey and registerurl support -z, I had to give them a --batch
option. The implicit batch mode they enter when not provided with input
parameters does not support -z as that would have complicated option
parsing. Seemed better to move these toward using the same --batch as
everything else, though the implicit batch mode can still be used.

avoid duplicate add action for v6 unlocked modified file
The new second pass sees the file as type changed because the first
pass's changes have typically not reached git yet. So, have to
explicitly check for unmodified files in the second pass.

Note that, if the file has been touched but not really modified,
the first pass will handle it, and so the second pass does nothing.

change v6 git-annex add of staged unmodified unlocked file
v6: When a file is unlocked but has not been modified, and the unlocking is
only staged, git-annex add did not lock it. Now it will, for consistency
with how modified files are handled and with v5.

Note the removal of the sameInodeCache check. Otherwise it would see
that the unmodified file is unmodified and stop there. That check seems to have
been copied from the direct mode branch. But, direct mode had a specific
reason to check for unmodified content, that does not apply to v6.

The second pass means there is potential for a race, eg the unlocked
file could be modified in between the first and second passes.
No problem with that, since both passes do the same thing.

Although I had to add a todo item as git-annex forget won't clean up

avoid sync/assistant drop from appendonly
Make git-annex sync and the assistant skip trying to drop from appendonly
remotes since it's just going to fail.

git-annex drop and similar commands will still try to drop from
appendonly, so the user will see failure messages when they try to do
that. To do otherwise would be confusing since the user has explicitly
asked for a drop with those commands.

v6: avoid accidental conversion when annex.largefiles is not configured
v6: When annex.largefiles is not configured for a file, running git add or
git commit, or otherwise using git to stage a file will add it to the annex
if the file was in the annex before, and to git otherwise. This is to avoid
accidental conversion.

Note that git-annex add's behavior has not changed, for reasons explained
in the added comment.

Performance: No added overhead when annex.largefiles is configured.
When not configured, there is an added call to catObjectMetaData,
which involves a round trip through git cat-file --batch.
However, the earlier catKeyFile primes the cache for it.

finally fixed v6 get/drop git status
After updating the worktree for an add/drop, update git's index, so git
status will not show the files as modified.

What actually happens is that the index update removes the inode
information from the index. The next git status (or similar) run
then has to do some work. It runs the clean filter.

So, this depends on the clean filter being reasonably fast and on git
not leaking memory when running it. Both problems were fixed in
a96972015d, but only for git 2.5. Anyone
using an older git will see very expensive git status after an add/drop.

This uses the same git update-index queue as other parts of git-annex, so
the actual index update is fairly efficient. Of course, updating the index
does still have some overhead. The annex.queuesize config will control how
often the index gets updated when working on a lot of files.

This is an imperfect workaround... Added several todos about new
problems this workaround causes. Still, this seems a lot better than the
old behavior.

massive v6 add speed/memory improvement
v6 add: Take advantage of improved SIGPIPE handler in git 2.5 to speed up
the clean filter by not reading the file content from the pipe. This also
avoids git buffering the whole file content in memory.

When built with an older git, still consumes stdin. If built with a newer
git and used with an older one, it breaks, but that's acceptable --
checking the git version every time would make repeated smudge runs slow.

make --batch honor matching options
When --batch is used with matching options like --in, --metadata, etc, only
operate on the provided files when they match those options. Otherwise, a
blank line is output in the batch protocol.

Affected commands: find, add, whereis, drop, copy, move, get

In the case of find, the documentation for --batch already said it honored
the matching options. The docs for the rest didn't, but it makes sense to
have them honor them. While this is a behavior change, why specify the
matching options with --batch if you didn't want them to apply?

Note that the batch output for all of the affected commands could
already output a blank line in other cases, so batch users should
already be prepared to deal with it.

git-annex metadata didn't seem worth making support the matching options,
since all it does is output metadata or set metadata, the use cases for
using it in combination with the martching options seem small. Made it
refuse to run when they're combined, leaving open the possibility for later
support if a use case develops.

cache remotes via annex-speculate-present
Added remote.name.annex-speculate-present config that can be used to
make cache remotes.

Implemented it in Remote.keyPossibilities, which is used by the
get/move/copy/mirror commands, and nothing else. This way, things like
whereis will not show content that's speculatively present.

The assistant and sync --content were not using Remote.keyPossibilities,
and were changed to use it.

The efficiency hit should be small; Remote.keyPossibilities is only
used before transferring a file, which is the expensive operation.
And, it's only doing one lookup of the remoteList and a very cheap
filter over it.

Note that, git-annex still updates the location log when copying content
to a remote with annex-speculate-present set. In this case, the location
tracking will indicate that content is present in the remote. This may
not be wanted for caches, or may not be a real problem for them. TBD.

enforce retrievalSecurityPolicy
Leveraged the existing verification code by making it also check the
retrievalSecurityPolicy.

Also, prevented getViaTmp from running the download action at all when the
retrievalSecurityPolicy is going to prevent verifying and so storing it.

Added annex.security.allow-unverified-downloads. A per-remote version
would be nice to have too, but would need more plumbing, so KISS.
(Bill the Cat reference not too over the top I hope. The point is to
make this something the user reads the documentation for before using.)

A few calls to verifyKeyContent and getViaTmp, that don't
involve downloads from remotes, have RetrievalAllKeysSecure hard-coded.
It was also hard-coded for P2P.Annex and Command.RecvKey,
to match the values of the corresponding remotes.

A few things use retrieveKeyFile/retrieveKeyFileCheap without going
through getViaTmp.
* Command.Fsck when downloading content from a remote to verify it.
  That content does not get into the annex, so this is ok.
* Command.AddUrl when using a remote to download an url; this is new
  content being added, so this is ok.

limit url downloads to whitelisted schemes
Security fix! Allowing any schemes, particularly file: and
possibly others like scp: allowed file exfiltration by anyone who had
write access to the git repository, since they could add an annexed file
using such an url, or using an url that redirected to such an url,
and wait for the victim to get it into their repository and send them a copy.

* Added annex.security.allowed-url-schemes setting, which defaults
  to only allowing http and https URLs. Note especially that file:/
  is no longer enabled by default.

* Removed annex.web-download-command, since its interface does not allow
  supporting annex.security.allowed-url-schemes across redirects.
  If you used this setting, you may want to instead use annex.web-options
  to pass options to curl.

With annex.web-download-command removed, nearly all url accesses in
git-annex are made via Utility.Url via http-client or curl. http-client
only supports http and https, so no problem there.
(Disabling one and not the other is not implemented.)

Used curl --proto to limit the allowed url schemes.

Note that this will cause git annex fsck --from web to mark files using
a disallowed url scheme as not being present in the web. That seems
acceptable; fsck --from web also does that when a web server is not available.

youtube-dl already disabled file: itself (probably for similar
reasons). The scheme check was also added to youtube-dl urls for
completeness, although that check won't catch any redirects it might
follow. But youtube-dl goes off and does its own thing with other
protocols anyway, so that's fine.

Special remotes that support other domain-specific url schemes are not
affected by this change. In the bittorrent remote, aria2c can still
download magnet: links. The download of the .torrent file is
otherwise now limited by annex.security.allowed-url-schemes.

This does not address any external special remotes that might download
an url themselves. Current thinking is all external special remotes will
need to be audited for this problem, although many of them will use
http libraries that only support http and not curl's menagarie.

The related problem of accessing private localhost and LAN urls is not
addressed by this commit.

export: re-send lost exported files after fsck notices they're gone
When content has been lost from an export remote and  git-annex fsck --from
remote has noticed it's gone, re-running git-annex export or git-annex sync
--content will re-upload it.

Note that normally there's no way to remove a single file from an export.
doc/design/exporting_trees_to_special_remotes.mdwn talks about this
in the section "dropping from exports and copying to exports". But, if
a file is somehow deleted or corrupted on the export, and fsck notices
this, it will update the location log to say it's missing.

So, checking the location log when determining if a file needs to be sent
to the export will let such missing files be added back in. There's
otherwise no way to do so. It does not fall afoul of the races documented
in the abovementioned section, I think.

Fix build with ghc 8.4+, which broke due to the Semigroup Monoid change
https://prime.haskell.org/wiki/Libraries/Proposals/SemigroupMonoid

I am not happy with the fragile pile of CPP boilerplate required to support
ghc back to 7.0, which git-annex still targets for both the android build
and the standalone build targeting old linux kernels. It makes me unlikely
to want to use Semigroup more in git-annex, because the benefit of the
abstraction is swamped by the ugliness. I actually considered ripping out
all the Semigroup instances, but some are needed to use
optparse-applicative.

The problem, I think, is they made this transaction on too fast a timeline.
(Although ironically, work on it started in 2015 or earlier!)
In particular, Debian oldstable is not out of security support, and it's
not possible to follow the simpler workarounds documented on the wiki and
have it build on oldstable (because the semigroups package in it is too
old).

I have only tested this build with ghc 8.2.2, not the newer and older
versions that branches of the CPP support. So there could be typoes, we'll
see.

are not affected by a view. Or non-annexed files in general which would
prevent view branch checkout from proceeding. But in other cases,
particularly unstaged changes to annexed files, entering a view would wipe
out those changes! And so don't allow entering a view with any unstaged
changes.

Staged changes are not safe when entering a view, because the changes get
committed to the view branch, and so the user is unlikely to remember them
when they exit the view, and so will effectively lose them, even if they're
still present in the view branch.

Also, improved the git status parser, although the improvement turned out
to not really be needed.

reuse hashes of dotfiles/dirs/submodules when entering view
This fixes a crash when a git submodule has a name starting with a dot.
Such a submodule might contain dotfiles that are intended to be used when
inside the view (since a dot-directory that's not a submodule was already
preserved when entering a view). So, rather than eliminating the submodule
from the view, its git ls-files --stage hash is copied over into the view.

dotfiles/dirs have their git ls-files --stage hashes similarly copied over
to the view. This is more efficient and simpler than the old method,
and also won't break if git ever adds a new type of tree item, like was
done with submodules.

Since the content of dotfiles in the working tree is no longer hashed
when entering a view, when there are unstaged modifications, they are
not included in the view branch. Entering the view branch still works,
but git checkout shows "M .dotfile", and git diff will show the unstaged
changes. This seems like an improvement over the old behavior.

Also made Command.View not delete empty directories that are submodules
when entering a view, while still deleting other empty directories.

filterM also kills laziness, so made loggedKeys use a Unchecked type,

Note that loggedKeysFor still buffers, so git-annex info <remote> and

Fix mangling of --json output of utf-8 characters when not running in a utf-8 locale
As long as all code imports Utility.Aeson rather than Data.Aeson,
and no Strings that may contain utf-8 characters are used for eg, object
keys via T.pack, this is guaranteed to fix the problem everywhere that
git-annex generates json.

It's kind of annoying to need to wrap ToJSON with a ToJSON', especially
since every data type that has a ToJSON instance has to be ported over.
However, that only took 50 lines of code, which is worth it to ensure full
coverage. I initially tried an alternative approach of a newtype FileEncoded,
which had to be used everywhere a String was fed into aeson, and chasing
down all the sites would have been far too hard. Did consider creating an
intentionally overlapping instance ToJSON String, and letting ghc fail
to build anything that passed in a String, but am not sure that wouldn't
pollute some library that git-annex depends on that happens to use ToJSON
String internally.

Use http-conduit for url downloads by default, annex.web-options enables curl
* For url downloads, git-annex now defaults to using a http library,
  rather than wget or curl. But, if annex.web-options is set, it will
  use curl. To use the .netrc file, run:
    git config annex.web-options --netrc
* git-annex no longer uses wget (and wget is no longer shipped with
  git-annex builds).

Note that curl is always run in silent mode, since the new API for
download has a MeterUpdate and doesn't make way for curl progress
output. It might be worth writing a parser for curl's progress output
to update the meter when using it, but I didn't bother with this edge
case for now.

better HTTP connection reuse
Enable HTTP connection reuse across multiple files, when git-annex
uses http-conduit. Before, a new Manager was created each time
Utility.Url used it. Now, a single Manager gets created the first time,
so connections are reused.

Doesn't help when external programs are used for url download,
but does speed up addurl --fast, fsck --from web, etc.

Testing fsck --fast --from web with 3 files, over high-latency
satellite internet, it sped up from 19.37s to 14.96s.

Fix reversion introduced in 6.20171214 that caused concurrent transfers to incorrectly fail with "transfer already in progress".
Avoid creating transfer info file before transfer lock is created and
locked.

The wrong order for one thing caused transfer info to be overwritten
when a transfer was already in progress.

But worse, it caused checkTransfer to see the transfer info,
and so lock the transfer lock in order to verify the transfer was not in
progress. Which in a concurrent situation, prevented the transferrer
from locking the transfer lock, so it failed with "transfer already in
progress".

Note that the transferinfo command does not lock the transfer lock
before creating the transfer info. But, that's only run after
recvkey is running, and recvkey does lock the transfer lock, so that
seems more or less ok. (Other than being a super complicated legacy mess
that the P2P code has mostly obsoleted now.)

deal with unlocked files
P2P protocol version 1 adds VALID|INVALID after DATA; INVALID means the
file was detected to change content while it was being sent and so we
may not have received the valid content of the file.

Added new MustVerify constructor for Verification, which forces
verification even when annex.verify=false etc. This is used when INVALID
and in protocol version 0.

As well as changing git-annex-shell p2psdio, this makes git-annex tor
remotes always force verification, since they don't yet use protocol
version 1. Previously, annex.verify=false could skip verification when
using tor remotes, and let bad data into the repository.

use total size from DATA
Noticed that getting a key whose size is not known resulted in a
progress display that didn't include the percent complete.

Fixed for P2P by making the size sent with DATA be used to update the
meter's total size.

In order for rateLimitMeterUpdate to also learn the total size,
had to make it be passed the Meter, and some other reorg in
Utility.Metered was also done so that --json-progress can construct a
Meter to pass to rateLimitMeterUpdate.

When the fallback rsync is done, the progress display still doesn't
include the percent complete. Only way to fix that seems to be to let rsync
display its output again, but that would conflict with git-annex's
own progress meter, which is also being displayed.

version the P2P protocol
Unfortunately ReceiveMessage didn't handle unknown messages the way it
was documented to; client sending VERSION would cause the server to
return an ERROR and hang up. Fixed that, but old releases of git-annex
use the P2P protocol for tor and will still have that behavior.

So, version is not negotiated for Remote.P2P connections, only for
Remote.Git connections, which will support VERSION from their first
release. There will need to be a later flag day to change Remote.P2P;
left a commented out line that is the only thing that will need to be
changed then.

Version 1 of the P2P protocol is not implemented yet, but updated

p2p ssh connection pools
Much like Remote.P2P, there's a pool of connections to a peer, in order
to support concurrent operations.

Deals with old git-annex-ssh on the remote that does not support p2pstdio,
by only trying once to use it, and remembering if it's not supported.

Made p2pstdio send an AUTH_SUCCESS with its uuid, which serves the dual
purposes of something to detect to see that the connection is working,
and a way to verify that it's connected to the right uuid.
(There's a redundant uuid check since the uuid field is sent
by git_annex_shell, but I anticipate that being removed later when
the legacy git-annex-shell stuff gets removed.)

Not entirely happy with Remote.Git.runSsh's behavior
when the proto action fails. Running the fallback will work ok, but what
will we do when the fallbacks later get removed? It might be better to
try to reconnect, in case the connection got closed.

make sure that lockContentShared is always paired with an inAnnex check
lockContentShared had a screwy caveat that it didn't verify that the content
was present when locking it, but in the most common case, eg indirect mode,
it failed to lock when the content is not present.

That led to a few callers forgetting to check inAnnex when using it,
but the potential data loss was unlikely to be noticed because it only
affected direct mode I think.

Fix data loss bug when the local repository uses direct mode, and a
locally modified file is dropped from a remote repsitory. The bug
caused the modified file to be counted as a copy of the original file.
(This is not a severe bug because in such a situation, dropping
from the remote and then modifying the file is allowed and has the same
end result.)

And, in content locking over tor, when the remote repository is
in direct mode, it neglected to check that the content was actually
present when locking it. This could cause git annex drop to remove
the only copy of a file when it thought the tor remote had a copy.

So, make lockContentShared do its own inAnnex check. This could perhaps
be optimised for direct mode, to avoid the check then, since locking
the content necessarily verifies it exists there, but I have not bothered
with that.
