include locked files in the keys database associated files
Before only unlocked files were included.

The initial scan now scans for locked as well as unlocked files. This
does mean it gets a little bit slower, although I optimised it as well
as I think it can be.

reconcileStaged changed to diff from the current index to the tree of
the previous index. This lets it handle deletions as well, removing
associated files for both locked and unlocked files, which did not
always happen before.

On upgrade, there will be no recorded previous tree, so it will diff
from the empty tree to current index, and so will fully populate the
associated files, as well as removing any stale associated files
that were present due to them not being removed before.

reconcileStaged now does a bit more work. Most of the time, this will
just be due to running more often, after some change is made to the
index, and since there will be few changes since the last time, it will
not be a noticable overhead. What may turn out to be a noticable
slowdown is after changing to a branch, it has to go through the diff
from the previous index to the new one, and if there are lots of
changes, that could take a long time. Also, after adding a lot of files,
or deleting a lot of files, or moving a large subdirectory, etc.

Command.Lock used removeAssociatedFile, but now that's wrong because a
newly locked file still needs to have its associated file tracked.

Command.Rekey used removeAssociatedFile when the file was unlocked.
It could remove it also when it's locked, but it is not really
necessary, because it changes the index, and so the next time git-annex
run and accesses the keys db, reconcileStaged will run and update it.

There are probably several other places that use addAssociatedFile and
don't need to any more for similar reasons. But there's no harm in
keeping them, and it probably is a good idea to, if only to support
mixing this with older versions of git-annex.

However, mixing this and older versions does risk reconcileStaged not
running, if the older version already ran it on a given index state. So
it's not a good idea to mix versions. This problem could be dealt with
by changing the name of the gitAnnexKeysDbIndexCache, but that would
leave the old file dangling, or it would need to keep trying to remove
it.

decided not to include export/import trees
They're only needed to cover a gc edge case, and it's better someone
gets caught by that edge case than that someone who does not know about
them ends up with a filtered git-annex branch that contains such a tree
when some of the files listed in it are ones they wanted to *remove*
from the repository.

include info for sameas repos
It's not currently possible to exclude a sameas repo using its
annex-config-uuid. (Remote.nameToUUID rejects them).
Since there's no real documented way to learn those, this seems ok, at
least for now. Also it avoids the problem of someone excluding the
parent but including the sameas, which would probably make the sameas
repo not usable when using the filtered branch.

filter-branch working aside from some edge cases
Added a note to man page about what happens to information that is
recorded in the private journal. Since it uses Branch.get, that
information will be copied when options allow. It seemed better to allow
it and document it than not allow it, since the options allow excluding
repositories and so can be used to exclude private repos if desired.

implemented filter-branch for key info
Not tested yet but should work.

Noted a possible optimisation, which should probably be added, to
speed it up in cases where there is no uuid filtering being done.
It would need Annex.Branch to add a function like getRef that uses
catFileDetails, so the sha is also returned. The difficulty would be
making it support the precached file content; if it didn't it would
probably not be any faster and could even be slower. So probably the
precaching would need to be changed to also cache the sha.

don't implicitly include all when exclude options are used
This is less erorr-prone, and easier for the user to reason about; it
preserves the man page's promise that only explicitly included
information will be copied.

assistant: Fix a crash on startup by avoiding using forkProcess
ghc 8.8.4 seems to have changed something that broke code that has been
successfully using forkProcess since 2012. Likely a change to GC internals.

Since forkProcess has never had clear documentation about how to
use it safely, avoid using it at all. Instead, when git-annex needs to
daemonize itself, re-run the git-annex command, in a new process group
and session.

remove inode cache in unannex
Similar to what commit 675556fd9a did for
adding a non-annexed file, this prevents the smudge clean filter
recognising the inode if git add is later run on the unannexed file.

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.

fileRef: make paths relative and simplified
Fix behavior of several commands, including reinject, addurl, and rmurl
when given an absolute path to an unlocked file, or a relative path that
leaves and re-enters the repository.

To avoid slowing down all the cases where the paths are already ok
with an unncessary call to getCurrentDirectory, put in an optimisation
in relPathCwdToFile. That will probably also speed up other parts of
git-annex by some small amount, but I have not benchmarked.

Note that I did not convert branchFileRef, because it seems likely that
it will be used with a file that is not provided by the user, so is already
in a sane format. This is certainly true for the way git-annex uses it,
though maybe arguable to the extent Git.Ref is a reusable library.

fromkey unlocked files support
fromkey: Create an unlocked file when used in an adjusted branch where the
file should be unlocked, or when configured by annex.addunlocked.

There is some overlap with code in Annex.Ingest, however it's not quite the
same because ingesting has a temp file with the content, where here the
content, if any, is in the annex object file. So it eg, makes sense for
Annex.Ingest to copy the execute mode of the content file, but it does not make
sense for fromkey to do that.

Also changed in passing to stage the file in git directly, rather than
using git add. One consequence of that is that if the file is gitignored,
it will still get added, rather than the old behavior:

The following paths are ignored by one of your .gitignore files:
ignored
hint: Use -f if you really want to add them.
hint: Turn this message off by running
hint: "git config advice.addIgnoredFile false"
git-annex: user error (xargs ["-0","git","--git-dir=.git","--work-tree=.","--literal-pathspecs","add","--"] exited 123)

That old behavior was a surprise to me, and so I consider it a bug, and doubt
anyone would have relied on it.

Note that, when on an --hide-missing branch, it is possible to fromkey a key
that is not present (needs --force). The annex link or pointer file still gets
written in this case. It doesn't seem to make any sense not to write it,
because then fromkey would not do anything useful in this case, and this way
the file can be committed and synced to master, and the branch re-adjusted to
hide the new missing file.

importfeed: fix bug while also speeding up 12x!
* Fix bug that could make git-annex importfeed not see recently recorded
  state when configured with annex.alwayscommit=false.
* importfeed: Made "checking known urls" phase run 12 times faster.

The massive speedup is because it no longer queries for metadata
accompanying each url. Instead it processes the whole git-annex branch and
checks all metadata files for feed item ids, and uses any it finds.

This could result in a behavior change, in an unlikely situation: If a feed
id is recorded in a key's metadata, but the url gets removed, the old code
would not see that item id and would re-download it if it finds an url for
it in a feed, while the new code will see the item id. I don't think
the old behavior was intentional, and it may be that the new behavior is
better. Not gonna worry about this.

start implementing hidden git-annex repositories
This adds a separate journal, which does not currently get committed to
an index, but is planned to be committed to .git/annex/index-private.

Changes that are regarding a UUID that is private will get written to
this journal, and so will not be published into the git-annex branch.

All log writing should have been made to indicate the UUID it's
regarding, though I've not verified this yet.

Currently, no UUIDs are treated as private yet, a way to configure that
is needed.

The implementation is careful to not add any additional IO work when
privateUUIDsKnown is False. It will skip looking at the private journal
at all. So this should be free, or nearly so, unless the feature is
used. When it is used, all branch reads will be about twice as expensive.

It is very lucky -- or very prudent design -- that Annex.Branch.change
and maybeChange are the only ways to change a file on the branch,
and Annex.Branch.set is only internal use. That let Annex.Branch.get
always yield any private information that has been recorded, without
the risk that Annex.Branch.set might be called, with a non-private UUID,
and end up leaking the private information into the git-annex branch.

And, this relies on the way git-annex union merges the git-annex branch.
When reading a file, there can be a public and a private version, and
they are just concacenated together. That will be handled the same as if
there were two diverged git-annex branches that got union merged.

fsck: avoid redundant checksum when transfer is Verified

switch from hslogger to purpose-built Utility.Debug
This uses a DebugSelector, rather than debug levels, which will allow
for a later option like --debug-from=Process to only
see debuging about running processes.

The module name that contains the thing being debugged is used as the
DebugSelector (in most cases; does not need to be a hard and fast rule).
Debug calls were changed to add that. hslogger did not display
that first parameter to debugM, but the DebugSelector does get
displayed.

Also fastDebug will allow doing debugging in places that are used in
tight loops, with the DebugSelector coming from the Annex Reader
essentially for free. Not done yet.

start splitting out readonly values from AnnexState
Values in AnnexRead can be read more efficiently, without MVar overhead.
Only a few things have been moved into there, and the performance
increase so far is not likely to be noticable.

This is groundwork for putting more stuff in there, particularly a value
that indicates if debugging is enabled.

The obvious next step is to change option parsing to not run in the
Annex monad to set values in AnnexState, and instead return a pure value
that gets stored in AnnexRead.

add git ls-tree --long parser
Not yet used, but allows getting the size of items in the tree fairly
cheaply.

I noticed that CmdLine.Seek uses ls-tree and the feeds the files into
another long-running process to check their size. That would be an
example of a place that might be sped up by using this. Although in that
particular case, it only needs to know the size of unlocked files, not
locked. And since enabling --long probably doubles the ls-tree runtime
or more, the overhead of using it there may outwweigh the benefit.

whereis: Don't include yt: prefix when showing url to content retrieved with youtube-dl
I don't think this was really intentional behavior. It may be that it was
useful to include it so it could be passed to rmurl, since without it rmurl
would not actually remove the url. Since that was changed earlier today,
now seems like a good time to clean up the display of these urls.

rmurl: remove all forms of an url, no matter what the downloader is set to
* rmurl: When youtube-dl was used for an url, it no longer needs to be
  prefixed with "yt:" in order to be removed.
* rmurl: If an url is both used by the web and also claimed by another
  special remote, fix a bug that caused the url to to not be removed.

The youtube-dl change is a consequence of how the bug fix is implemented.
But I also think it's the right thing to do. Consider that, before,
git-annex addurl $url followed by git-annex rmurl $url would not remove the
url in the case where youtube-dl was used. That was surprising behavior.

In the unlikely case where a special remote claims an url, and it's been
added using OtherDownloader, but it was also added already as a web url,
it seems better for rmurl to remove both than to arbitrarily remove only one.

And in the case the bug report was filed for, when an url was added as a
web url, but a special remote now claims it, that should not prevent rmurl
removing the web url.

Calling setUrlMissing lets other callers of it behave differently.
Probably the calls to it in eg, Remote.External and Remote.BitTorrent are
fine, since they don't mangle the url and just remove what was provided,
and the OtherDownloader form of a bittorrent url, respectively.
I suspect unregisterurl needs to have a similar change made to rmurl, for
similar reasons.

avoid logging location of GIT keys
It's not necessary to log location of GIT keys, because these files are
not annexed files and so git-annex will never need to get them.

This corresponds to code in Annex.Import that already checked before
updating the location log when handling deleted files.

Older versions of git-annex that used SHA1 keys for non-annexed files
also unncessarily updated the location log for them.

GIT keys still appear in the git-annex branch for content identifier
logs, so kept the documentation of them in backends.mdwn

use GIT keys for export of non-annexed files
This solves the problem that import of such files gets confused and
converts them back to annexed files.

The import code already used GIT keys internally when it determined a
file should not be annexed. So now when it sees a GIT key that export
used, it already does the right thing.

This also means that even older version of git-annex can import and will
do the right thing, once a fixed version has exported. Still, there may
be other complications around upgrades; still need to think it all
through.

Moved gitShaKey and keyGitSha from Key to Annex.Export since they're
only used for export/import.

Documented GIT keys in backends, since they do appear in the git-annex
branch now.

don't use it when MatchingInfo is provided. This should be ok,
the --branch case will be able skip checking matchNeedsFileName,
since it will provide a filename in any case.

avoid making absolute git remote path relative
When a git remote is configured with an absolute path, use that path,
rather than making it relative. If it's configured with a relative path,
use that.

Git.Construct.fromPath changed to preserve the path as-is,
rather than making it absolute. And Annex.new changed to not
convert the path to relative. Instead, Git.CurrentRepo.get
generates a relative path.

A few things that used fromAbsPath unncessarily were changed in passing to
use fromPath instead. I'm seeing fromAbsPath as a security check,
while before it was being used in some cases when the path was
known absolute already. It may be that fromAbsPath is not really needed,
but only git-annex-shell uses it now, and I'm not 100% sure that there's
not some input that would cause a relative path to be used, opening a
security hole, without the security check. So left it as-is.

Test suite passes and strace shows the configured remote url is used
unchanged in the path into it. I can't be 100% sure there's not some code
somewhere that takes an absolute path to the repo and converts it to
relative and uses it, but it seems pretty unlikely that the code paths used
for a git remote would call such code. One place I know of is gitAnnexLink,
but I'm pretty sure that git remotes never deal with annex symlinks. If
that did get called, it generates a path relative to cwd, which would have
been wrong before this change as well, when operating on a remote.

suggest when user may want annex.stalldetection
When annex.stalldetection is not enabled, and a likely stall is detected,
display a suggestion to enable it.

Note that the progress meter display is not taken down when displaying
the message, so it will display like this:

	0%    8 B                 0 B/s
	  Transfer seems to have stalled. To handle stalling transfers, configure annex.stalldetection
	0%    10 B                0 B/s

Although of course if it's really stalled, it will never update
again after the message. Taking down the progress meter and starting
a new one doesn't seem too necessary given how unusual this is,
also this does help show the state it was at when it stalled.

Use of uninterruptibleCancel here is ok, the thread it's canceling
only does STM transactions and sleeps. The annex thread that gets
forked off is separate to avoid it being canceled, so that it
can be joined back at the end.

A module cycle required moving from dupState the precaching of the
remote list. Doing it at startConcurrency should cover all the cases
where the remote list is used in concurrent actions.

When adding files to an adjusted branch set up by --unlock-present, add them unlocked, not locked
Missed this when implementing it because of the default case catching
the new constructor. So, removed that default case to make sure
future types of adjusted branches don't make the same mistake.

Complicated by git-annex addurl --fast which adds the file whose content
is not present, so it needs to stay unlocked when on such a branch.

fix breakage caused by recent commit
34a535ebea broke the test suite.
Getting a file started failing in one case, because the annex object did
not have its inode cached, so was not trusted to be unmodified.

This adds something very similar to what was added to linkAnnex
in commit 2e9341a47d -- if there are not
yet any inodes cached for a key, add the inode of the annex object when
adding the inode of the unlocked file.

Feels like this should be handled in a more principled way. How
do we know the addInodeCaches call in getMoveRaceRecovery just above
this change is currently correct? It doesn't add the annex object inode
cache. Ah well, maybe sometime when I've not had my entire evening eaten
by a reversion that the test suite caught as I was cooking dinner.

adjust: Fix some bad behavior when unlocked files use URL keys.
This avoids the smudge --clean filter failing on the URL keys.

git checkout runs the post-checkout hook, which runs smudge --update.
That populates all the pointer files, but it neglected to store their inode
caches in the keys db. With that done, and the keys db flushed before
smudge --clean gets run (by restagePointerFile), the isUnmodifiedCheap
check can tell the file is not modified, so will not try to re-ingest it,
which does not work with URL keys because they do not support genKey.

It also seems possible that the isUnmodifiedCheap was also failing for
non-URL keys, which would cause them to be re-ingested, leading to a lot of
extra work. I have not verified that, but don't see why it wouldn't have
happened. So this probably also speeds up checking out adjusted branches.

test: avoid unnecessary tests of variants of git remote
Configuring chunking and encryption for a git remote has no effect, so
skip testing those variants in the TestRemote call.

It would be better if TestRemote itself could do this, but it
doesn't seem possible there. There is no way to look at a Remote and
tell if it supports chunking or encryption.

Note that, while the test suite displays output as it it's testing
exporting, it actually skips doing anything for the tests when run on
the git remote. So at least does not waste time even though the output
is not ideal.

Behavior change: git-annex trust now needs --force
Since unconsidered use of trusted repositories can lead to data loss.

Trusted has always been this way, but it used to be acceptable for

mincopies
This is conceptually very simple, just making a 1 that was hard coded be
exposed as a config option. The hard part was plumbing all that, and
dealing with complexities like reading it from git attributes at the
same time that numcopies is read.

Behavior change: When numcopies is set to 0, git-annex used to drop
content without requiring any copies. Now to get that (highly unsafe)
behavior, mincopies also needs to be set to 0. It seemed better to
remove that edge case, than complicate mincopies by ignoring it when
numcopies is 0.

add thirdPartyPopulated interface
This is to support, eg a borg repo as a special remote, which is
populated not by running git-annex commands, but by using borg. Then
git-annex sync lists the content of the remote, learns which files are
annex objects, and treats those as present in the remote.

So, most of the import machinery is reused, to a new purpose. While
normally importtree maintains a remote tracking branch, this does not,
because the files stored in the remote are annex object files, not
user-visible filenames. But, internally, a git tree is still generated,
of the files on the remote that are annex objects. This tree is used
by retrieveExportWithContentIdentifier, etc. As with other import/export
remotes, that  the tree is recorded in the export log, and gets grafted
into the git-annex branch.

importKey changed to be able to return Nothing, to indicate when an
ImportLocation is not an annex object and so should be skipped from
being included in the tree.

It did not seem to make sense to have git-annex import do this, since
from the user's perspective, it's not like other imports. So only
git-annex sync does it.

Note that, git-annex sync does not yet download objects from such
remotes that are preferred content. importKeys is run with
content downloading disabled, to avoid getting the content of all
objects. Perhaps what's needed is for seekSyncContent to be run with these
remotes, but I don't know if it will just work (in particular, it needs
to avoid trying to transfer objects to them), so I skipped that for now.

(Untested and unused as of yet.)

check Remote.hasKeyCheap again
In cd1676d604, it stopped using that to avoid surprising behavior
when the location log and remote content were out of sync.
But, it seems that may have changed some behavior users relied on as
well, and also Remote.hasKeyCheap should be faster than checking then
location log.

So, try Remote.hasKeyCheap first, and only if it does not have the key,
fall back to checking the location log. If the location log still thinks
it's present, go ahead and try to get it, so the user will see a failure
rather than silently skipping a file what whereis says is on the remote.

This does make slightly slower the case where the remote does not have
the key, and location log and Remote.hasKeyCheap agree, since it now
checks both. But only 1 stat slower.

custom protocol for transferrer
Rather than using Read/Show, which would force me to preserve data types
into the future.

I considered just deriving json and sending that, but I don't much like
deriving json with data types that have named constructors (like Key
does) because again it locks in data type details.

So instead, used SimpleProtocol, with a fairly complex and unreadable
protocol. But it is as efficient as the p2p protocol at least, and as
future proof.

(Writing my own custom json instances would have worked but I thought
of it too late and don't want to do all the work twice. The only real
benefit might be that aeson could be faster.)

Note that, when a new protocol request type is added later, git-annex
trying to use it will cause the git-annex transferrer to display a
protocol error message. That seems ok; it would only happen if a new
git-annex found an old version of itself in PATH or the program
file. So it's unlikely, and all it can do anyway is display an error.
(The error message could perhaps be improved..)

refactoring
This is groundwork for using git-annex transferkeys to run transfers,
in order to allow stalled transfers to be interrupted and retried.

The new upload and download are closer to what git-annex transferkeys
does, so the plan is to make them use it.

Then things that were left using upload' and download' won't recover
from stalls. Notably, that includes import and export. But
at least get/move/copy will be able to. (Also the assistant hopefully,
but not yet.)
