This reverts commit cee12f6a2f.
This commit broke git-annex init run in a repo that was cloned from a
repo with an adjusted branch checked out.
The problem is that findAdjustingCommit was not able to identify the
commit that created the adjusted branch. It seems that there is an extra
"\n" at the end of the commit message that it does not expect.
Since backwards compatability needs to be maintained, cannot just make
findAdjustingCommit accept it with the "\n". Will have to instead
have one commitTree variant that uses the old method, and use it for
adjusted branch committing.
sync, assist, import: Allow -m option to be specified multiple times, to
provide additional paragraphs for the commit message.
The option parser didn't allow multiple -m before, so there is no risk of
behavior change breaking something that was for some reason using multiple
-m already.
Pass through to git commands, so that the method used to assemble the
paragrahs is whatever git does. Which might conceivably change in the
future.
Note that git commit-tree has supported -m since git 1.7.7. commitTree
was probably not using it since it predates that version. Since the
configure script prevents building git-annex with git older than 2.1,
there is no risk that it's not supported now.

Bug fix: Re-running git-annex adjust or sync when in an adjusted branch
would overwrite the original branch, losing any commits that had been made
to it since the adjusted branch was created.
When git-annex adjust is run in this situation, it will display a warning
about the diverged branches.
When git-annex sync is run in this situation, mergeToAdjustedBranch
will merge the changes from the original branch to the adjusted branch.
So it does not need to display the divergence warning.
Note that for some reason, I'm needing to run sync twice for that to
happen. The first run does not do the merge and the second does. I'm unsure
why and so am not fully done with this bug.

Speeds up sync in an adjusted branch by avoiding re-adjusting the branch
unncessarily, particularly when it is adjusted with --hide-missing or
--unlock-present.
When there are a lot of files, that was the majority of the time of a
--no-content sync.
Uses a log file, which is updated when content presence changes. This
adds a little bit of overhead to every file get/drop when on such an
adjusted branch. The overhead is minimal for get of any size of file,
but might be noticable for drop in some cases. It seems like a reasonable
trade-off. It would be possible to update the log file only at the end, but
then it would not happen if the command is interrupted.
When not in an adjusted branch, there should be no additional overhead.
(getCurrentBranch is an MVar read, and it avoids the MVar read of
getGitConfig.)
Note that this does not deal with situations such as:
git checkout master, git-annex get, git checkout adjusted branch,
git-annex sync. The sync won't know that the adjusted branch needs to be
updated. Dealing with that would add overhead to operation in non-adjusted
branches, which I don't like. Also, there are other situations like having
two adjusted branches that both need to be updated like this, and switching
between them and sync not updating.
This does mean a behavior change to sync, since it did previously deal
with those situations. But, the documentation did not say that it did.
The man pages only talk about sync updating the adjusted branch after
it transfers content.
I did consider making sync keep track of content it transferred (and
dropped) and only update the adjusted branch then, not to catch up to other
changes made previously. That would perform better. But it seemed rather
hard to implement, and also it would have problems with races with a
concurrent get/drop, which this implementation avoids.
And it seemed pretty likely someone had gotten used to get/drop followed by
sync updating the branch. It seems much less likely someone is switching
branches, doing get/drop, and then switching back and expecting sync to update
the branch.
Re-running git-annex adjust still does a full re-adjusting of the branch,
for anyone who needs that.

Introduced recently in commit 64fc34b3da.
adjustBranch changes the sha that is recorded for the current branch
(eg the adjusted branch). So, have to get the original sha before
calling it.

Updating an adjusted branch can take a while when there are a lot of
files. HEAD was detached at the start, so if eg git-annex sync was
interrupted at the wrong point, there was a possibly wide window where
it would leave the repo with HEAD detached.
There's still a window, just much narrower. I don't know if it's
possible to close the window entirely. While git can clearly update
the currently checked out branch in eg git merge, it doesn't seem to
provide another way to do it.

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.
This does, as a side effect, make warning messages in json output not
be indented. The indentation is only needed to offset warning messages
underneath the display of the file they apply to, so that's ok.

Fix laziness bug introduced in last release that breaks use of
--unlock-present and --hide-missing adjusted branches.
Since there is a writeFile of the same file immediately after readFile, it
may still have the file open for read (or may have happened to read it
already and closed it).
I was not able to reproduce the problem in brief testing, but this seems
obvious.

Avoid failure to update adjusted branch --unlock-present after git-annex
drop when annex.adjustedbranchrefresh=1
At higher values, it did flush the queue, which ran restagePointerFiles.
But at 1, adjustedBranchRefreshFull gets added to the queue, and while
restagePointerFiles is also in the queue, it runs after that.

When git-annex adjust is run in a view branch, and the adjusted branch
already exists, overwrite the old adjusted branch with the new one
without being forced.
Usually overwriting an adjusted branch is avoided because it could lose
data. But when a view branch has been adjusted, there is no data to lose
in the adjusted branch, because the only changes that can be made of
significance are to move files between directories. Which changes
metadata on commit. And the old branch has already been committed.

* sync: When --quiet is used, run git commit, push, and pull without
their ususual output.
* merge: When --quiet is used, run git merge without its usual output.
This might also make --quiet work better for some other commands
that make commits, like git-annex adjust.

init: Fix a crash when the repo's was cloned from a repo that had an
adjusted branch checked out, and the origin remote is not named "origin".
The only other hardcoding of the name of origin is in:
- Upgrade.V2, which can be ignored probably
- Annex.Branch, which doesn't fail if it has some other name, but just
doesn't set up the git-annex branch with quite as linear a history in
that case.
Done on unix, could not implement it on windows quite.
The signal library gets part of the way needed for windows.
But I had to open https://github.com/pmlodawski/signal/issues/1 because
it lacks raiseSignal.
Also, I don't know what the equivilant of getProcessGroupIDOf is on
windows. And System.Process does not provide a way to send any signal to
a process group except for SIGINT.

Added annex.adjustedbranchrefresh git config to update adjusted branches
set up by git-annex adjust --unlock-present/--hide-missing.
Note, in a few cases, I was not able to make the adjusted branch
be updated in calls to moveAnnex, because information about what
file corresponds to a key is not available. They are:
* If two files point to one file, then eg, `git annex get foo` will
update the branch to unlock foo, but will not unlock bar, because it
does not know about it. Might be fixable by making `git annex get
bar` do something besides skipping bar?
* git-annex-shell recvkey likewise (so sends over ssh from old versions
of git-annex)
* git-annex setkey
* git-annex transferkey if the user does not use --file
* git-annex multicast sends keys with no associated file info
Doing a single full refresh at the end, after any incremental refresh,
will deal with those edge cases.
An --unlock-present branch reverses back to a branch where
all files that get modified or renamed become locked, even if they were
originally unlocked. This is the same that reversing a --unlock branch
works, and the new name makes that commonality more clear.
Like --hide-missing the branch does not get updated when content
availability changes.
Seems to basically work, but sync does not update it yet.
Also, when a file is present and so unlocked, git mv followed by
git-annex sync results in the basis branch being updated to contain the
file with the new name, unlocked. This seems different than what
happens in an adjusted unlocked branch, where the commit propigates back
locked. Probably the reverse adjustment code needs to be improved to
handle this case.
Works better with automatic merge conflict resolution than git's ususual
default of "conflict".
This is not done when automatic merge conflict resolution is disabled.

Git will eventually switch to sha2 and there will not be one single
shaSize anymore, but two (40 and 64).
Changed all parsers for git plumbing output to support both sizes of
shas.
One potential problem this does not deal with is, if somewhere in
git-annex it reads two shas from different sources, and compares them
to see if they're the same sha, it would fail if they're sha1 and sha256
of the same value. I don't know if that will really be a concern.
Adds a dependency on filepath-bytestring, an as yet unreleased fork of
filepath that operates on RawFilePath.
Git.Repo also changed to use RawFilePath for the path to the repo.
This does eliminate some RawFilePath -> FilePath -> RawFilePath
conversions. And filepath-bytestring's </> is probably faster.
But I don't expect a major performance improvement from this.
This is mostly groundwork for making Annex.Location use RawFilePath,
which will allow for a conversion-free pipleline.
When the submodule's parent repo has an adjusted unlocked branch,
it gets cloned by git, but git checks out master. git annex init then
fails because it wants to enter the adjusted branch, but:
adjusted branch adjusted/master(unlocked) already exists.
Aborting because that branch may have changes that have not yet reached master
Note that init actually then exits 0, leaving master checked out.
This could also happen, absent submodules, if the parent repo has
an adjusted unlocked branch, but it is not checked out. In the more common
case where that branch is checked out, the clone uses the same branch,
so no problem.
The choices to fix this:
* Init could delete the existing adjusted branch, and re-adjust.
But then running init inside an adjusted branch on a crippled filesystem
would lose any changes that have not been synced back to master.
* Init could sync any changes back to master, but that would be very surprising
behavior for it.
* Init could simply check out the existing adjusted branch. If the branch
is diverged from master, well, sync will sort that out later.
This mirrors the behavior of cloning a repo that has an adjusted branch
checked out that has not yet been synced back to master.
Picked this choice.
Prevents merging the import from deleting the non-preferred files from
the branch it's merged into.
adjustTree previously appended the new list of items to the old, which
could result in it generating a tree with multiple files with the same
name. That is not good and confuses some parts of git. Gave it a
function to resolve such conflicts.
That allowed dealing with the problem of what happens when the import
contains some files (or subtrees) with the same name as files that were
filtered out of the export. The files from the import win.
* Switch to using .git/annex/othertmp for tmp files other than partial
downloads, and make stale files left in that directory when git-annex
is interrupted be cleaned up promptly by subsequent git-annex processes.
* The .git/annex/misctmp directory is no longer used and git-annex will
delete anything lingering in there after it's 1 week old.
Also, in Annex.Ingest, made the filename it uses in the tmp dir be
prefixed with "ingest-" to avoid potentially using a filename used by
some other code.
* init: When a crippled filesystem causes an adjusted unlocked branch to
be used, set repo version to 7, which it neglected to do before.
* init: When on a crippled filesystem, and the git version is too old
to use an adjusted unlocked branch, fall back to using direct mode.

It was trying to git annex adjust when in a direct mode repo, and that
of course fails. What I don't understand though, is how the test suite
managed to work before, when it was clearly checking the wrong thing.
Since the right way to fix it was obvious, I have not bisected.

This completes initial support for --hide-missing, although the
assistant still needs to be updated and it perhaps needs to be sped up,
and maybe there needs to be a way for git-annex get to operate on
missing files. Opened some more todos for those things.

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.

* 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.
