catch all (non-async) exceptions when running a commandAction
When a command is operating on multiple files and there's an error with
one, try harder to continue to the rest. (As was already done for many
types of errors including IO errors.)

This handles cases like lockContentForRemoval throwing an exception when
the content is already locked. Just because a drop of one file fails, does
not mean it shouldn't go on to try to drop other files.

I looked over uses of `giveup` in Command/*; there are too many to check
them all extensively, but none stood out as being problems that should let
one commandAction stop running other commandActions. Worst case, something
bad will happen and rather than stopping right away with an error,
git-annex will display multiple errors as it fails over and over on each
file. I don't think I ever really intended `error`/`giveup` to stop other
commandActions; this was a relic of old confusion over haskell exception
handling.

Test suite passes.

avoid redundant export uploads
export, sync --content: Avoid unnecessarily trying to upload files to an
exporttree remote that already contains the files.

When the export was origianly made in one repo and now git-annex is
running in a different repo, the export database is not yet populated with
information about the exportLocation of files. So, it was trying to upload
the files to the export, even when it already contained them.

sync --content would first download the content from the export, and then
re-upload the content back.

And this also led to "not available" failures for each file that was not
locally present yet.

Fix: Just use checkPresentExport before uploading; if it succeeds update
the database.

This is a surprising oversight, it's possible it fixes a reversion because
I would have thought I'd have noticed this problem when originally
developing exporttree remotes.

Fix resume of download of url when the whole file content is already actually downloaded
Don't much like that there's no way to distinguish between having the whole
content and having an old version of the file that's bigger, but of course
resuming a http transfer can always yield the wrong result if the file on
the http server is changing, and git-annex will detect that when it
verifies the downloaded content.

Fixed some other potential hangs in the P2P protocol
Finishes the start made in 983c9d5a53, by
handling the case where `transfer` fails for some other reason, and so the
ReadContent callback does not get run. I don't know of a case where
`transfer` does fail other than the locking dealt with in that commit, but
it's good to have a guarantee.

StoreContent and StoreContentTo had a similar problem.
Things like `getViaTmp` may decide not to run the transfer action.
And `transfer` could certianly fail, if another transfer of the same
object was in progress. (Or a different object when annex.pidlock is set.)

If the transfer action was not run, the content of the object would
not all get consumed, and so would get interpreted as protocol commands,
which would not go well.

My approach to fixing all of these things is to set a TVar only
once all the data in the transfer is known to have been read/written.
This way the internals of `transfer`, `getViaTmp` etc don't matter.

So in ReadContent, it checks if the transfer completed.
If not, as long as it didn't throw an exception, send empty and Invalid
data to the callback. On an exception the state of the protocol is unknown
so it has to raise ProtoFailureException and close the connection,
same as before.

In StoreContent, if the transfer did not complete
some portion of the DATA has been read, so the protocol is in an unknown
state and it has to close the conection as well.

(The ProtoFailureMessage used here matches the one in Annex.Transfer, which
is the most likely reason. Not ideal to duplicate it..)

StoreContent did not ever close the protocol connection before. So this is
a protocol change, but only in an exceptional circumstance, and it's not
going to break anything, because clients already need to deal with the
connection breaking at any point.

The way this new behavior looks (here origin has annex.pidlock = true so will
only accept one upload to it at a time):

git annex copy --to origin -J2
copy x (to origin...) ok
copy y (to origin...)
  Lost connection (fd:25: hGetChar: end of file)

git-annex-shell: fix transfer hang
Fix hang when transferring the same objects to two different clients at the
same time. (Or when annex.pidlock is used, two different objects to the
same or different clients.)

Could also potentially occur if a client was downloading an object and
somehow lost connection but that git-annex-shell was still running and
holding the transfer lock.

This does not guarantee that, if `transfer` fails for some other reason,
a DATA response will be made.

Fix test suite failure when git-annex test is not run inside a git repository
Not the first time this kind of test suite breakage has happened..
It would be good to avoid somehow it looking up from .t and finding a git

git-annex would also let me notice these before the distribution packagers

importfeed: Avoid erroring out when a feed has been repeatedly broken
That can leave other imported files not checked into git, because the git
command queue is not flushed when git-annex errors out. And since it only
happens once git-annex has concluded a feed is broken, it's an intermittent
bug, worst kind. Been seeing it for a while, only tracked down today.

Instead, by returning False, git-annex importfeed will cleanly shutdown and
still exit nonzero.

Fix a P2P protocol hang
When readContent got Nothing from prepSendAnnex, it did not run its
callback, and the callback is what sends the DATA reply.

sendContent checks with contentSize that the object file is present, but
that doesn't really guarantee that prepSendAnnex won't return Nothing.

So, it was possible for a P2P protocol GET to not receive a response,
and appear to hang. When what it's really doing is waiting for the next
protocol command.

This seems most likely to happen when the annex is in direct mode, and the
file being requested has been modified. It could also happen in an indirect
mode repository if genInodeCache somehow failed. Perhaps due to a race
with a drop of the content file.

Fixed by making readContent behave the way its spec said it should,
and run the callback with L.empty in this case.

Note that, it's finee for readContent to send any amount of data
to the callback, including L.empty. sendBytes deals with that
by making sure it sends exactly the specified number of bytes,
aborting the protocol if it's too short. So, when L.empty is sent,
the protocol will end up aborting.

remove CHECKURL-MULTI single url response special case
Removed undocumented special case in handling of a CHECKURL-MULTI response
with only a single file listed. Rather than ignoring the url that was in
the response, use it. This allows external special remotes that want to
provide some better url to do so, although I don't entirely agree with
using CHECKURL-MULTI to accomplish that. I'm more of the feeling that an
undocumented special case that throws data away is just not a good idea.

This could in theory break some external special remote program that relied
on the current behavior, but its seems unlikely that it would because such
a program must already handle the multiple url case, unless it only ever
provides a single url response to CHECKURL-MULTI.

Make addurl --file work with a single item CHECKURL-MULTI response.
It already did for external special remotes due to the special case,
but now it also will for builtin ones like the BitTorrent special remote.

When annex.thin is set, allow hard links to be made between executable work tree files and annex objects.
This is safe, because while the annex object ends up executable,
there were already at least two other cases where it ended up executable:

1. git add an an executable file
2. chmod +x of a a non-executable worktree file that was hard linked to the
   annex object

After copy/hard link, it always fixes up the permissions to match the mode
of the worktree file, so when an executable annex object gets hard linked
to a non-executable worktree file, its execute bit gets removed.

Commit b7c8bf5274 already *said* it would do
this; I suspect the line of code I've removed was included in that commit
accidentially.

Also improves annex.thin documentation.

v7
Install new git hooks in this version.

This does beg the question of what to do if git later gets eg a
post-smudge hook, that could run git-annex smudge --update. I think the
thing to do in that case would be to make git-annex smudge --update
install the new hooks. That way, as the user uses git-annex, the hook
would be created pretty quickly and without needing any extra syscalls
except for when git-annex smudge --update is called.

I considered doing something like that for installation of the
post-checkout and post-merge hooks, which would have avoided the need
for v7. But the only place it was cheap to do it would be in git-annex smudge
which could cheaply notice that smudge.log didn't exist yet and so know
the hooks needed to be installed. But since smudge used to populate pointer
files, it would be quite surprising if a single git checkout/merge failed
to update the work tree, and so that idea didn't work out.

The other reason for v7 is psychological -- users don't need to worry
about whether they might be running an old version of git-annex that
doesn't support their v7 repository very well. And bug reports about
"v6" have gotten a bit of a bad association in my head since they often
hit one of the known limitations and didn't realize it was experimental.

newtyped RepoVersion Int to avoid needing 2 comparisons in
versionSupportsUnlockedPointers etc. Also it's just nicer.

git post-checkout and post-merge hooks
* init, upgrade: Install git post-checkout and post-merge hooks that run
  git annex smudge --update.
* precommit: Run git annex smudge --update, because the post-merge
  hook is not run when there is a merge conflict. So the work tree will
  be updated when a commit is made to resolve the merge conflict.
* precommit: Run git annex smudge --update, because the post-merge
  hook is not run when there is a merge conflict. So the work tree will
  be updated when a commit is made to resolve the merge conflict.
* Note that git has no hooks run after git stash or git cherry-pick,
  so the user will have to manually run git annex smudge --update
  after such commands.

Nothing currently installs the hooks into v6 repos that already exist.
Something will need to be done about that, either move this behavior to v7,
or document that the user will need to manually fix up their v6 repos.

make sync update adjusted branch to hide/unhide

sync --content now supports --hide-missing adjusted branches
This relies on git ls-files --with-tree, which I'm using in a way that
its man page does not document. Hm. I emailed the git list to try to get
the docs improved, but at least the git test suite does test the same
kind of use case I'm using here.

Performance impact when not in an adjusted branch is limited to some
additional MVar accesses, and a single git call to determine the name of
the current branch. So very minimal.

When in an adjusted branch, the performance impact is
in Annex.WorkTree.lookupFile, which starts doing an equal amount of work
for files that didn't exist as it already did for files that were
unlocked.

v6: Fix database inconsistency
That could cause git-annex to get confused about whether a locked file's
content was present, when the object file got touched.

Unfortunately this means more work sometimes when annex.thin is set,
since it has to checksum the file to tell if it's still got the right
content.

Had to suppress output when inAnnex calls isUnmodified, otherwise
"(checksum...)" would be printed in places it ought not to be,
eg "git annex get" could turn out not need to get anything, and
so only display that.

runshell: Use system locales when built with GIT_ANNEX_PACKAGE_INSTALL set
This is to work around https://github.com/datalad/datalad/issues/2769
which I don't know how to reproduce outside that environment, nor do I
understand the root cause of. For some time, Neurodebian has been working
around it by building its standalone debs with a patch that disables use
of the locales bundled with the standalone build, letting the system
locales be used.

Using the system locales is asking for trouble if there's
significant version skew between the system and bundled glibc, and
possibly also if the architeciture is different, or whatever. That's why
git-annex bundles and uses its own locales, because numerous users
reported real problems with using the system locales.

... However, in the specific case of the Neurodebian standalone debs,
the deb is built on a system very like the one it's targeted to be
installed on. Or well, so they assure me, although doc/install/Ubuntu.mdwn
also promotes those for use across all versions of Ubuntu, and the deb
is built avoiding xz so it will work with old versions of dpkg, so I wonder
how true it is. It does seem that, at least currently, there is no bad
version skew in the locales of the systems the deb is used on, since
it's already been using the system locales for some time.

Anyway, since the Neurodebian build already is setting
GIT_ANNEX_PACKAGE_INSTALL=1 in runshell, I made runshell use system
locales when that's set. This is a small scope creep for
GIT_ANNEX_PACKAGE_INSTALL, but it's not documented and AFAIK only used
for the Neurodebian build, so that seems ok. This will let them stop
carrying their patch for this forward.

only reason to keep the Android app would be to support Android 4-5, which

51% one year ago.

Also, removed support for building with very old ghc < 8.0.1, and with

Runshell runs termux-fix-shebang on the shell scripts. The problem is
the bundled bin/sh script, deleting that script also works, but then the

Fix potential crash in exporttree database due to failure to honor uniqueness constraint

ErrorConstraint while attempting to perform step.

All 3 tables in the export db have uniqueness constraints on them,
insertUnique is used for all the rest, but this use of insertMany
means it doesn't check the constraint. I guess that's what caused the
crash, but I have not been able to test it yet.
