pull, sync: When operating on content, automatically hard link objects
that have been migrated.
Added annex.syncmigrations config that can be set to false to prevent
pull and sync from migrating object content.
I think that true is a good default for this config, because it avoids
users having to re-download migrated content or learning about migration.
But, some users will surely not like it, whether because it does take some
time (especially for the first git-annex branch scan when there is a long
history), or because they want to deal with it manually, or because their
filesystem doesn't support hard links and they don't want it to copy
objects.

Presumably git merge sometimes needs to verifiy if a worktree file is
modified, and so will then run git-annex filter-process which would try to
take the pid lock. And for whatever reason, git-annex sync already had the
pidlock held. I have not replicated that, but it does make enough sense to
deploy the workaround.
Like I said back in commit 7bdb0cdc0d,
Arguably, it would be better to have a way to make any process git-annex
runs have the env var set. But then it would need to take the pid lock
when running any and all processes, and that would be a problem when
git-annex runs two processes concurrently. So, I'm left doing it ad-hoc
in places where git-annex really does run a child process, directly
or indirectly via a particular git command.

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.

push: When on an adjusted branch, propagate changes to parent branch before
updating export remotes.
This is a somewhat redundant call to propigateAdjustedCommits, since it
also gets called at pushLocal time. That other one needs to come after
importing from importtree remotes though, and seekExportContent has to come
earlier, so I don't see a way to avoid doing it twice.
Note that git-annex sync also manages to avoid the problem, it's only
git-annex push that had the bug.

A misleading message was displayed in several cases.
If the user has run eg: git config
remote.push-win-remote.annex-tracking-branch 'adjusted/main(unlocked)'
That is not supported, and now it will tell them it's not a valid
configuration. A user reported doing that, but I don't know if it's a
common point of confusion. If it is a common problem, a better message
would be possible, or it could convert back from the adjusted branch to
the actual branch.

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.

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.

Command.Add.seek starts concurrency with CommandStages. And for
Command.Sync, it needs TransferStages. So, to get both types of concurrency
for the two different parts, it either needs to change the type of
concurrency in between, or just call startConcurrency once for each.
It seems safe enough to call startConcurrency twice, because it does shut
down concurrency (mostly) at the end, and eg the old Annex.workers get
emptied.

This ended up having an interface like sync, rather than like get/copy/drop.
That let it be implemented in terms of sync, which took a lot less code.
Also, it lets it handle many of the edge cases that sync does, such as
getting files that are not visible in a --hide-missing branch, and sending
files to exporttree remotes.
As well as being easier to implement, `git-annex satisfy myremote` makes
sense as it satisfies the preferred content settings of the remote.
`git-annex satisfy somefile` does not form a sentence that makes sense. So
while -C can be a little bit annoying, it still makes sense to have this
syntax.
Note that, while I initially thought this would also satisfy numcopies, it
does not. Arguably it ought to. But, sync does not send files in order to
satisfy numcopies, it only sends files to satisfy preferred content. And
it's important that this transfer the same files as sync does, because
it will probably be used in a workflow where the user sometimes syncs and
sometimes satisfies, and does not expect satisfy to do things that sync
would not do.
(Also opened a new bug that also affects sync et all, not only this command.)

That will fail, and it already exports whole trees.
f6dd34ca81 made it sync content with
import remotes, and if an import remote is also an export remote, that
caused this new failure mode.
Sponsored-by: Brock Spratlen on Patreon
This didn't used to be needed because importKeys would import all
content and so doing another pass was redundant.
But since 40017089f2 it uses
importChanges, so only new files are imported. If a file that was
already imported before was dropped, that would prevent sync --content
from gettng its content again.

Large speed up to importing trees from special remotes that contain a lot
of files, by only processing changed files.
Benchmarks:
Importing from a special remote that has 10000 files, that have all been
imported before, and 1 new file sped up from 26.06 to 2.59 seconds.
An import with no change and 10000 unchanged files sped up from 24.3 to
1.99 seconds.
Going up to 20000 files, an import with no changes sped up from
125.95 to 3.84 seconds.

For simplicity, I've not tried to make it handle History yet, so when
there is a history, a full import will still be done. Probably the right
way to handle history is to first diff from the current tree to the last
imported tree. Then, diff from the current tree to each of the
historical trees, and recurse through the history diffing from child tree
to parent tree.
I don't think that will need a record of the previously imported
historical trees, and so Logs.Import doesn't store them. Although I did
leave room for future expansion in that log just in case.
Next step will be to change importTree to importChanges and modify
recordImportTree et all to handle it, by using adjustTree.

assist: New command, which is the same as git-annex sync but with
new files added and content transferred by default.
(Also this fixes another reversion in git-annex sync,
--commit --no-commit, and --message were not enabled, oops.)
See added comment for why git-annex assist does commit staged
changes elsewhere in the work tree, but only adds files under
the cwd.
Note that it does not support --no-commit, --no-push, --no-pull
like sync does. My thinking is, why should it? If you want that
level of control, use git commit, git annex push, git annex pull.
Sync only got those options because pull and push were not split

When used without --content or --no-content, warn about the upcoming
transition, and suggest using one of the options, or setting
annex.synccontent.
Sponsored-by: Brett Eisenberg on Patreon
This option is not specific to sync, so it seemed it should be in either
pull or push as well as sync. Since it does modify the remote, it seems
better to have it in push; the modification of the local repo pulls in
the direction of pull, but not hard enough.
Maybe it would be better to have it in both?

I anticipate that if sync is transitioned to syncing content by default,
people will want a short option. And in repositories where
annex.synccontent = true, they already would. And pull and push sync
content by default, so a short option is useful with them too.
Mnemonic: -g makes only git data be synced
Also, -a makes only annex data be synced.
Would have preferred -c, which would complement -C, but it
was already taken to set git configs.

Split out two new commands, git-annex pull and git-annex push. Those plus a
git commit are equivilant to git-annex sync.
In a sense, git-annex sync conflates 3 things, and it would have been
better to have push and pull from the beginning and not sync. Although
note that git-annex sync --content is faster than a pull followed by a
push, because it only has to walk the tree once, look at preferred
content once, etc. So there is some value in git-annex sync in speed, as
well as user convenience.
And it would be hard to split out pull and push from sync, as far as the
implementaton goes. The implementation inside sync was easy, just adjust
SyncOptions so it does the right thing.
Note that the new commands default to syncing content, unless
annex.synccontent is explicitly set to false. I'd like sync to also do
that, but that's a hard transition to make. As a start to that
transition, I added a note to git-annex-sync.mdwn that it may start to
do so in a future version of git-annex. But a real transition would
necessarily involve displaying warnings when sync is used without
--content, and time.

The man page is somewhat vague about this, but I do think it was a bug
that these options didn't alreay behave that way. The options are
documented to disable imports and exports, which is the same operations
just with a special remote that uses trees.
The real motivation for this is that I'm adding git-annex pull and
git-annex push, and I want these options to turn off the equivilant of
those commands. And git-annex pull will certianly download and push
upload.

When a nonexistant file is passed to a command and --json-error-messages
is enabled, output a JSON object indicating the problem.
(But git ls-files --error-unmatch still displays errors about such files in
some situations.)
I don't like the duplication of the name of the command introduced by this,
but I can't see a great way around it. One way would be to pass the Command
instead.
When json is not enabled, the stderr is unchanged. This is necessary
because some commands like find have custom output. So dislaying
"find foo not found" would be wrong. So had to complicate things with
toplevelFileProblem having different output with and without json.
When not using --json-error-messages but still using --json, it displays
the error to stderr, but does display a json object without the error. It
does have an errorid though. Unsure how useful that behavior is.

Converted warning and similar to use StringContainingQuotedPath. Most
warnings are static strings, some do refer to filepaths that need to be
quoted, and others don't need quoting.
Note that, since quote filters out control characters of even
UnquotedString, this makes all warnings safe, even when an attacker
sneaks in a control character in some other way.
When json is being output, no quoting is done, since json gets its own
quoting.

Such an url is not valid; parseURI will fail on it. But git-annex doesn't
actually need to parse the url, because all it needs to do to support
syncing with it is know that it's not a local path, and use git pull and
push.
(Note that there is no good reason for the user to use such an url. An
absolute url is valid and I patched git-remote-gcrypt to support them
years ago. Still, users gonna do anything that tools allow, and
git-remote-gcrypt still supports them.)

When generating the view, check if the key is present.
When syncing in a view branch with an adjustment, run adjustedBranchRefreshFull
the same as is done when syncing in other adjusted branches. This is

using git-annex sync to update the branch when annex.adjustedbranchrefresh
is not set.
Note that, with annex.adjustedbranchrefresh set, it just works! The
adjusted branch gets updated in the usual way and it doesn't matter that
there's a view branch underneath.
And of course, re-running git-annex adjut --unlock-present also works,

Existing view branches checked out using an old name will still work.
It does not seem useful for sync to push view branches around, because
the information in a view branch can entirely be derived from other
information in git. And sync doesn't push adjusted branches around either.
The better view branch names make it more in line with adjusted branch
names, but were also needed to make fromViewBranch be able to return the
original branch name.
Kept the old view branch names still working. But, when those branches
exist in a repo, sync will still try to push them as before. Avoiding
that would need more complicated and/or expensive changes to sync.

Use separate stages for download and upload. In the common case where
it downloads the file from one remote and then uploads to the other,
those are by far the most expensive operations, and there's a decent
chance the two remotes bottleneck on different resources.
Suppose it's being run with -J2 and a bunch of 10 mb files. Two threads
will be started both downloading from the src remote. They will probably
finish at the same time. Then two threads will be started uploading to
the dst remote. They will probably take the same time as well. Before
this change, it would alternate back and forth, bottlenecking on src and dst.
With this change, as soon as the two threads start uploading to dst, two
more threads are able to start, downloading from src. So bandwidth to
both remotes is saturated more often.
Other commands that use transferStages only send in one direction at a
time. So the worker threads for the other direction will sit idle, and
there will be no change in their behavior.

when the command is run with an existing git-annex repo, not when it
creates a new one.
Also, renamed GlobalOption etc to AnnexOption. Because there are many
options of this type that are not actually global (any more) and get

sync: Better error message when unable to export to a remote because
remote.name.annex-tracking-branch is configured to a ref that does not

It does not suggest how to fix the problem because there are several
possible solutions: Change the git config to point to something that does
exist, git add some files, or put files on the special remote that will be
imported and so populate the ref.
I considered just silently not doing anything, which is what it does
when annex-tracking-branch = master and nothing has been committed to
master yet. But it seems better to be explicit about it, since this is a
fairly confusing situation to find yourself in.

sync --content: Avoid a redundant checksum of a file that was
incrementally verified, when used on NTFS and perhaps other filesystems.
When sync has just gotten the content, it does not need to check inAnnex a
second time. On NTFS, for some reason the write of the inode cache after
it gets the content is not immediately able to be read, and with an
empty/non-matching inode cache due to that stale data, inAnnex falls back
to hashing the whole object to determine if it's present.
