drop, move, mirror: when two files have the same content, honor the max numcopies and requiredcopies
Eg, before with a .gitattributes like:

*.2 annex.numcopies=2
*.1 annex.numcopies=1

And foo.1 and foo.2 having the same content and key, git-annex drop foo.1 foo.2
would succeed, leaving just 1 copy, despite foo.2 needing 2 copies.
It dropped foo.1 first and then skipped foo.2 since its content was gone.

Now that the keys database includes locked files, this longstanding wart
can be fixed.

verify associated files when checking numcopies
Most of this is just refactoring. But, handleDropsFrom
did not verify that associated files from the keys db were still
accurate, and has now been fixed to.

A minor improvement to this would be to avoid calling catKeyFile
twice on the same file, when getting the numcopies and mincopies value,
in the common case where the same file has the highest value for both.
But, it avoids checking every associated file, so it will scale well to
lots of dups already.

fix exponential blowup when adding lots of identical files
This was an old problem when the files were being added unlocked,
so the changelog mentions that being fixed. However, recently it's also
affected locked files.

The fix for locked files is kind of stupidly simple. moveAnnex already
handles populating unlocked files, and only does it when the object file
was not already present. So remove the redundant populateUnlockedFiles
call. (That call was added all the way back in
cfaac52b88, and has always been
unncessary.)

Future proof activity log parsing
When the log has an activity that is not known, eg added by a future
version of git-annex, it used to be treated as no activity at all,
which would make git-annex expire think it should expire the repository,
despite it having some kind of recent activity.

Hopefully there will be no reason to add a new activity until enough
time has passed that this commit is in use everywhere.

add --size-limit option
When this option is not used, there should be effectively no added
overhead, thanks to the optimisation in
b3cd0cc6ba.

When an action fails on a file, the size of the file still counts toward
the size limit. This was necessary to support concurrency, but also
generally seems like the right choice.

Most commands that operate on annexed files support the option.
export and import do not, and I don't know if it would make sense for
export to.. Why would you want an incomplete export? sync doesn't, and
while it would be easy to make it support it for transferring files,
it's not clear if dropping files should also take the size limit into
account. Commands like add that don't operate on annexed files don't
support the option either.

Exiting 101 not yet implemented.

New matching options --excludesamecontent and --includesamecontent
The normalisation of filenames turns out to be the tricky part here,
because the associated files coming out of the keys db may look like
"./foo/bar" or "../bar". For the former to match a glob like "foo/*",
it needs to be normalised.

Note that, on windows, normalise "./foo/bar" = "foo\\bar"
which a glob like "foo/*" won't match. So the glob is matched a second
time, on the toInternalGitPath, so allowing the user to provide a glob
with the slashes in either direction. However, this still won't support
some wacky edge cases like the user providing a glob of "foo/bar\\*"

prevent dropping required content of other file using same content
When two files have the same content, and a required content expression
matches one but not the other, dropping the latter file will fail as it
would also remove the content of the required file.

This will slow down drop (w/o --auto), dropunused, mirror, and move, by one
keys db lookup per file. But I did include an optimisation to avoid a
double db lookup in the drop --auto / sync --content case. I suspect that
dropunused could also use PreferredContentChecked True, but haven't
entirely thought it through and it's rarely used with enough files for the
optimisation to matter.

fix longstanding indeterminite preferred content for duplicated file problem
* drop: When two files have the same content, and a preferred content
  expression matches one but not the other, do not drop the file.
* sync --content, assistant: Fix an edge case where a file that is not
  preferred content did not get dropped.

The sync --content edge case is that handleDropsFrom loaded associated files
and used them without verifying that the information from the database was
not stale.

It seemed best to avoid changing --want-drop's behavior, this way when
debugging a preferred content expression with it, the files matched will
still reflect the expression. So added a note to the --want-drop documentation,
to make clear it may not behave identically to git-annex drop --auto.

While it would be possible to introspect the preferred content
expression to see if it matches on filenames, and only look up the
associated files when it does, it's generally fairly rare for 2 files to
have the same content, and the database lookup is already avoided when
there's only 1 file, so I did not implement that further optimisation.

Note that there are still some situations where the associated files
database does not get locked files recorded in it, which will prevent
this fix from working.

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.

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.

fix branch precacheing bug by checking journal
Fix bug caused by recent optimisations that could make git-annex not see
recently recorded status information when configured with
annex.alwayscommit=false.

When not using --all, precaching only gets triggered when the
command actually needs location logs, and so there's no speed hit there.

This is a minor speed hit for --all, because it precaches even when the
location log is not actually going to be used, and so checking the journal
is not necessary. It would have been possible to defer checking the journal
until the cache gets used. But that would complicate the usual Branch.get
code path with two different kinds of caches, and the speed hit is really
minimal. A better way to speed up --all, later, would be to avoid
precaching at all when the location log is not going to be used.

Not yet for imports from directory though, and not for store.

Note that, when it's chunked, using cp --reflink would not speed it up, and
when reflink was not supported, would unnecessarily write the chunk to a

NoChunks case is necessary to keep chunking fast.

fileCopier is told not to verify, because the special remote interface
does not yet support verification in passing. AFAICS, fileCopies can

Avoid excess commits to the git-annex branch when stall detection is enabled
When git-annex transferrer started up, and the journal contained something,
it would commit it to the git-annex branch. This caused excess commits to
the branch, in cases where normally several changes would be journalled and
committed together. That generated some excess git objects and was also
just noisy on stdout.

Since transferrer uses enableInteractiveBranchAccess, it does not need to
commit journalled changes, since the optimisation that avoids checking
the journal when reading from the branch is disabled for processes that
call that.

Fix bug importing from a special remote into a subdirectory more than one level deep
Which generated unusual git trees that could confuse git merge,
since they incorrectly had 2 subtrees with the same name.

Root of the bug was a) not testing that at all! but also
b) confusing graftdirs, which contains eg "foo/bar" with
non-recursively read trees, which would contain eg "bar"
when reading a subtree of "foo".

It's worth noting that Annex.Import uses graftTree, but it really
shouldn't have needed to. Eg, when importing into foo/bar from a remote,
it's enough to generate a tree of foo/bar/x, foo/bar/y, and does not
include other files that are at the top of the master branch. It uses
graftTree, so it does include the other files, as well as the foo/bar
tree. git merge will do the same thing for both trees. With that said,
switching it away from graftTree would result in another import
generating a new commit that seems to delete files that were there in a
previous commit, so it probably has to keep using graftTree since it
used it before.

result in listImportableContents reporting a file size of 0,
rather than the actual size of the file. One result is that
the progress meter when getting the file will seem to get stuck

if it tries to match against file size, will treat it as an empty file.
I don't see a way to improve the latter behavior, and the former behavior
is a minor enough problem.

borg: Fix a bug that prevented importing keys of type URL and WORM
Keys stored on the filesystem are mangled by keyFile to avoid problem
chars. So, that mangling has to be reversed when parsing files from a
borg backup back to a key.

The directory special remote also so mangles them. Some other special
remotes do not; eg S3 just serializes the key -- but S3 object names are
not limited to filesystem valid filenames anyway, so a S3 server must
not map them directly to files in any case. It seems unlikely that a
borg backup of some such special remote will get broken by this change.

webdav: deal with buggy webdav servers in renameExport
box.com already had a special case, since its renaming was known buggy.
In its case, renaming to the temp file succeeds, but then renaming the temp
file to final destination fails.

Then this 4shared server has buggy handling of renames across directories.
While already worked around with for the temp files when storing exports
now being in the same directory as the final filename, that also affected
renameExport when the file moves between directories.

I'm not entirely clear what happens on the 4shared server when it fails
this way. It kind of looks like it may rename the file to destination and
then still fail.

To handle both, when rename fails, delete both the source and the
destination, and fall back to uploading the content again. In the box.com
case, the temp file is the source, and deleting it makes sure the temp file
gets cleaned up. In the 4shared case, the file may have been renamed to the
destination and so cleaning that up avoids any interference with the
re-upload to the destination.

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 getting creds from environment during autoenable
When autoenabling special remotes of type S3, weddav, or glacier, do not
take login credentials from environment variables, as the user may not be
expecting the autoenable to happen, and may have those set for other
purposes.

export --json: Fill in the file field
Like import was using ActionItemWorkTreeFile, it's ok to use it for export,
even though it might not correspond with a file in the work tree.
And renamed it to ActionItemTreeFile to make that clearer.

Note that when an export has to rename files, it still uses
ActionItemOther, so file will still be null in that case, but as no file is
being transferred, that seems ok.

import: When the previously exported tree contained a submodule,
preserve it in the imported tree so it does not get deleted.

The export exclude log, which was used for non-preferred content,
now also includes the submodules. Since the log format is git ls-tree
output, this does not break backwards compatibility.

git on OSX dmg updated to fix CVE
This mostly affects OSX and (possibly) Windows, but the Windows
installer does not bundle git. The linux standalone builds are not
updated yet pending debian stable getting a backport of the security
fix, but the security hole is unlikely to affect linux as
case-insensitive filesystems that support symlinks are a rarity on it.
Using the linux standalone build on windows via WSL is another way it
could be affected.

Added support for git-remote-gcrypt's rsync URIs
Which access a remote using rsync over ssh, and which git pushes to much
more efficiently than ssh urls.

There was some old partial support for rsync URIs from 2013, but it seemed
incomplete, and did not use rsync over ssh. Weird.

I'm not sure if there's any remaining benefit to using the non-rsync url
forms with gcrypt, now that this is implemented? Updated docs to encourage
using the rsync urls.

Fix support for local gcrypt repositories with a space in their URI
Git.Remote.parseRemoteLocation had a hack to handle URIs that contained
characters like spaces, which is something git unfortunately allows
despite not being a valid URI. However, that hack looked for "//" to
guess something was an URI, and these gcrypt URIs, being to a local
path, don't contain that. So instead escape all illegal characters and
check if the resulting thing is an URI.

And that was already done by Git.Construct.fromUrl, so
internally the gcrypt URI with a space looks like "gcrypt::foo%20bar"
and that needs to be de-escaped when converting back from URI to local
repo path.

This change might also allow a few other almost-valid URIs to be handled
as URIs by git-annex. None that contain "//" will change, and any
behavior change should result in git-annex doing closer to a right thing
than it did before, probably.

Prevent combinations of options such as --all with --include
Previously such nonsensical combinations always treated the matching option
as if it didn't match.

For now, made find --branch refuse matching options that need a
filename, because one is not provided to them in a way they'll use.
There's an open bug report to support it, but making it error out is
better than the old behavior of not finding what it was asked to.

Also, made --mimetype combined with eg --all work, by looking at the
object file when operating on keys.

incremental checksum for local remotes
This benchmarks only slightly faster than the old git-annex. Eg, for a 1
gb file, 14.56s vs 15.57s. (On a ram disk; there would certianly be
more of an effect if the file was written to disk and didn't stay in
cache.)

Commenting out the updateIncremental calls make the same run in 6.31s.
May be that overhead in the implementation, other than the actual
checksumming, is slowing it down. Eg, MVar access.

(I also tried using 10x larger chunks, which did not change the speed.)

Bugfix: fsck --from a ssh remote did not actually check that the content on the remote is not corrupted
Changing to the P2P protocol broke this, because preseedTmp copies
the local copy of the object to the temp file, and then the P2P transfer
sees the right length file and uses it as-is.

When git-annex-shell is too old and rsync is used, it did verify the
content, and when the local repo does not have the object it did verify the
content.

incremental checksum on download from ssh or p2p
Checksum as content is received from a remote git-annex repository, rather
than doing it in a second pass.

Not tested at all yet, but I imagine it will work!

Not implemented for any special remotes, and also not implemented for
copies from local remotes. It may be that, for local remotes, it will
suffice to use rsync, rely on its checksumming, and simply return Verified.
(It would still make a checksumming pass when cp is used for COW, I guess.)

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.

addon commands
Seems only fair, that, like git runs git-annex, git-annex runs
git-annex-foo.

Implementation relies on O.forwardOptions, so that any options are passed
through to the addon program. Note that this includes options before the
subcommand, eg: git-annex -cx=y foo

Unfortunately, git-annex eats the --help/-h options.
This is because it uses O.hsubparser, which injects that option into each
subcommand. Seems like this should be possible to avoid somehow, to let
commands display their own --help, instead of the dummy one git-annex
displays.

The two step searching mirrors how git works, it makes finding
git-annex-foo fast when "git annex foo" is run, but will also support fuzzy
matching, once findAllAddonCommands gets implemented.

Seemed like a change to consume should be able to handle this case

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

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.

This is probably a reversion, but not sure what caused it. By the time
Annex.Init runs fixupUnusualReposAfterInit, another git-annex process has
at least sometimes already done the necessary fixups. (Eg, one run
indirectly by a git command.) But since the Repo is cached, it doesn't
realize and does them again. So, avoid crashing when git config --unset

omit inode from ContentIdentifier for directory special remote
Directory special remotes with importtree=yes now avoid unncessary overhead
when inodes of files have changed, as happens whenever a FAT filesystem
gets remounted.

A few unusual edge cases of modifications won't be detected and
imported. I think they're unusual enough not to be a concern. It would
be possible to add a config setting that controls whether to compare
inodes too, but does not seem worth bothering the user about currently.

I chose to continue to use the InodeCache serialization, just with the
inode zeroed. This way, if I later change my mind or make it
configurable, can parse it back to an InodeCache and operate on it. The
overhead of storing a 0 in the content identifier log seems worth it.

There is a one-time cost to this change; all directory special remotes
with importtree=yes will re-hash all files once, and will update the
content identifier logs with zeroed inodes.

Including the non-standard URI form that git-remote-gcrypt uses for rsync.

Eg, "ook://foo:bar" cannot be parsed because "bar" is not a valid port
number. But git could have a remote with that, it would try to run
git-remote-ook to handle it. So, git-annex has to allow for such things,
rather than crashing.
