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.

Implementation was simple because it's equivilant to
--from=foo --to remote for each other remote, followed by
--to remote when there's a local copy.
(Or, in the edge case of --from-anywhere --to=here,
it's the same as --to=here.)
Note that, when the local repo does not have a copy,
fromToPerform gets it from a remote, sends it to the destination,
and drops the local copy. Another call to that for a second remote
will notice that the dest now has a copy, and simply drop from the
second remote, avoiding a second transfer.
Also note that, when numcopies doesn't allow dropping it from
everywhere, it will drop it from the cheapest remotes first
(maybe not ideal) up to more expensive remotes, and finally from the local
repo. So the local repo will generally end up holding a copy. Maybe not
ideal in all cases either, but it seems no worse to do that than to end up
with a copy undropped from a remote.
And I'm not entirely happy with the output, eg:
copy bigfile (from r3...) ok
copy bigfile ok
That makes sense if you think of the second line as being
the same as what is output by `git-annex copy bigfile --to bar`,
but it's less clear in this context. Maybe add "(from here...)"?
Also the --json output doesn't have a machine-readable field for
the "from" uuid, and maybe it should?

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.

It's a semi-common point of confusion that numcopies is not something
these commands go out and copy files around specifically to satisfy,
without further configuration in preferred content. So this is a good
addition, but it also seemed too long and too specific to the user's
particular situation.
I got bitten several times in the past by the fact that local preferred
content expressions are not violated (even temporarily) in order to
satisfy numcopies or other remotes' preferred content expressions.
Mostly in the form of the local repo not allowing arbitrary files in
(e.g. because it's set to only want `present` files). This note I add
here explains how to get out of this situation with
`approxlackingcopies=1`.
It might be too specific for this manpage, but I didn't find a better
place to put it.
Eg when the destination is logged as containing a file, skip
actively checking that it does contain it.
Note that --fast does not prevent other verifications of content
location that are done in a copy --from --to. Perhaps it could, but this
change will already avoid the real unnecessary work of operating on
files that are already in the remote.
And avoiding other verifications
might cause it to fail if the location log thinks that --to does not
contain the content but does. Such complications with `git-annex copy
--to remote --fast` led to commit d006586cd0
which added a note that gets displayed when that fails, mentioning it
might be due to --fast being enabled.
copy --from --to is already complicated enough without needing to worry
about such edge cases, so continuing to doing some verification of
content location after the initial --fast filtering seems ok.

The gnuplot output is pretty good, but could still be improved with:
* more colors (repeating colors is confusing with a lot of repos)
* better positioning of the legend, making the plot wider and moving it
from over top of the graph

Only counting received and not dropped makes this show the bandwidth of
data coming into the repository, although only in a sense. Since
git-annex branch updates only happen at the end of a command, and we
don't know when a command started, it's only an approximation of the
actual bandwidth. (A previous git-annex branch update made have
happened in a different repository.)
It would be possible to also add a --dropped option, but I don't know
how useful that would be?

This can take a lot of memory. I decided to violate the usual rule in
git-annex that it operate in constant memory no matter how many annexed
objects. In this case, it would be hard to be fast without using a big
map of the location logs. The main difficulty here is that there can be
many git-annex branches and it needs to display a consistent view at a
point in time, which means merging information from multiple git-annex
branches.
I have not checked if there are any laziness leaks in this code. It
takes 1 gb to run in my big repo, which is around what I estimated
before writing it.
2 options that are documented are not yet implemented.
Small bug: With eg --when=1h, it will display at 12:00 then 1:10 if the
next change after 12:59 is then. Then it waits until after 2:10 to
display the next change. It ought to wait until after 2:00.

Factored out overLocationLogs from CmdLine.Seek, which can calculate this
pretty fast even in a large repo. In my big repo, the time to run git-annex
info went up from 1.33s to 8.5s.
Note that the "backend usage" stats are for annexed files in the working
tree only, not all annexed files. This new data source would let that be
changed, but that would be a confusing behavior change. And I cannot
retitle it either, out of fear something uses the current title (eg parsing
the json).
Also note that, while time says "402108maxresident" in my big repo now,
up from "54092maxresident", top shows the RES constant at 64mb, and it
was 48mb before. So I don't think there is a memory leak. I tried using
deepseq to force full evaluation of addKeyCopies and memory use didn't
change, which also says no memory leak. And indeed, not even calling
addKeyCopies resulted in the same memory use. Probably the increased memory
usage is buffering the stream of data from git in overLocationLogs.

Windows: When git-annex init is installing hook scripts, it will
avoid ending lines with CR for portability.
Existing hook scripts that do have CR line endings will not be changed.
While it would be possible to have git-annex init upgrade them, users would
need to know to use that command to do that, and it would add complexity
that does not seem warranted for the portability benefit alone.

This allows getting rid of the ugly and error prone handling of
"bag of bytes" String in Remote.Helper.Encryptable.
Avoiding breakage like that dealt with by commit
9862d64bf9
And allows converting Utility.Gpg to use ByteString for IO, which is
a welcome change.
Tested the new git-annex interoperability with old, using all 3
encryption= types.

This does not improve Annex.Branch.files at all, since it still uses ++ to
combine the lists, so forcing all but the last one.
But when there are a lot of files in the private journal, it does avoid
--all (or a bare repo) from buffering the filenames in memory.
See commit 653b719472 for prior discussion of
this buffering.

importfeed: Use caching database to avoid needing to list urls on every
run, and avoid using too much memory.
Benchmarking in my podcasts repo, importfeed got 1.42 seconds faster,
and memory use dropped from 203000k to 59408k.
Database.ImportFeed is Database.ContentIdentifier with the serial number
filed off. There is a bit of code duplication I would like to avoid,
particularly recordAnnexBranchTree, and getAnnexBranchTree. But these use
the persistent sqlite tables, so despite the code being the same, they
cannot be factored out.
Since this database includes the contentidentifier metadata, it will be
slightly redundant if a sqlite database is ever added for metadata. I
did consider making such a generic database and using it for this. But,
that would then need importfeed to update both the url database and the
metadata database, which is twice as much work diffing the git-annex
branch trees. Or would entagle updating two databases in a complex way.
So instead it seems better to optimise the database that
importfeed needs, and if the metadata database is used by another command,
use a little more disk space and do a little bit of redundant work to
update it.

The crash occurred because writeCreds got called twice, and writeFileProtected
neglected to close its file handle, so the file was open for write when
written the second time.
It seems unncessary and suboptimal that writeCreds gets called twice.
One call is from getRemoteCredPair and the other from setRemoteCredPair'.
What happens is that in the enableremote case, code that also runs at
initremote does unncessary work. Might be possible to improve that, but
I've gone for the simple fix.

git-annex only writes regular files there, but other things may drop junk
like empty .DAV directories around the tree. And trying to hash such things
can have weird and hard to understand effects. So it seems best to do a
small amount of work in statting the journal file to make sure it's a
regular file.
