This reverts commit 43d182a955.
In the dependencies for aws-0.23:
aeson-1.3.1.1 from stack configuration does not match >=2.0.0.0 (latest matching version
is 2.1.2.1)
So this will never be able to be updated to aws-0.23 probably.
crypton is a fork of cryptonite, and cryptonite's github repo has been
archived. Some deps are already using cryptonite so it's clearly the way
forward.
Added a build flag without a default, so cabal configure will select on its
own which to use. stack files pin to cryptonite for now.

AFAICS all git-annex builds are using the git-lfs library not the vendored
copy.
Debian stable now includes a new enough haskell-git-lfs package as well.
Last time this was tried it did not.
AFAICS all git-annex builds are using the git-lfs library not the vendored
copy.
Debian stable does have a too old haskell-git-lfs package to be able to
build git-annex from source, but there is not currently a backport of a
recent git-annex to Debian stable. And if they update the backport at some
point, they should be able to backport the library too.

aws-0.23 has been released.
When built with an older aws, initremote will error out when run
with signature=anonymous. And when a remote has been initialized with
that by a version of git-annex that does support it, older versions will
fail when the remote is accessed, with a useful error message.

For some reason, cabal 3.4.1.0 builds w/o the assistant and webapp,
even when the flag is explicitly turned on. Moving the build-depends from
inside the if flag section to the main build-depends somehow fixes this.
Since the webapp build deps are thus always available, there is no reason
not to build the webapp when building the assistant. So, got rid of the
webapp build flag. Kept the assistant build flag for now, since building
without it does at least still speed up the build.

Removed vendored copy of http-client-restricted, and removed the
HttpClientRestricted build flag that avoided that dependency.
http-client-restricted is in Debian stable, and the i386ancient build also
uses it, so I think this vendored copy is no longer needed.

This should let i386ancient limp along for a few years more, beyond the
removal of those vendored deps from git-annex.
Also networkbsd is set now, so probably the last thing to unset that
flag is gone, and the flag could be removed soon.

The new ansi-terminal was needed for test concurrency, and the new
concurrent-output fixes several bugs. And it turns out this is all
that's needed to use the new tasty.
Sponsored-by: Kevin Mueller on Patreon
Dependency issues were looking difficult to support tasty-1.2 with that
build. Not using `after` only affects rerunning and limiting tests,
since tasty's concurrency is not used, so this build will just not
support that.
We are probably nearing end of life on this build; it also doesn't
support git-lfs or http-client-restricted. The 2.6.32 kernel it supports
is at this point 13 years old, and stopped being supported by linux LTS
developers 10 years ago. It was supported by RHEL 6.10 through November
2020. At this point, no new hardware should be shipping with this
kernel, but that probably does not stop certian embedded vendors from
shipping it. And there is certainly some hardware still using it. But
the returns from supporting it are diminishing, and the quality of the
build for it is also diminishing.

It was moved to avoid a race, but that's now avoided in another way.
I prefer having it here, because this way if it somehow fails and
deletes the locpath that is going to be used, at least it will get
re-created.
Use a different tmp directory so the cache cleanup won't delete the
locpath directory while it's being populated.
This does change the hash used for the locpath directory, but it already
changed in f0ec725234
This fixes a race between two runshells from two different
bundles. One could have run the cache cleanup code, seen the
LOCPATH the other one was in the process of populating, which didn't
have a base or a buildid file written yet, and so the cache cleanup code
would delete it out from under the other process.
Also, doing it fully atomically simplifies where the races between two
runshell processes from the same bundle. Now that needs to be
dealt with to only the mv that puts it in place.
Note that, if the same bundle has 2 runshells run first thing, they will
both generate locales, which is unncessary work, but that should be a
very unusual circumstance and after the LOCPATH is set up, it won't
happen again anyway.
This should fix doc/bugs/standalone_runshell_can_race_and_fail_to_remove___96____126____47__.cache__47__git-annex__47__locales__47____96___dirs
where 2 runshells were running and the second one tried to clean up
LOCPATH while the first one was still populating it.
By moving the cleanup until after LOCPATH is populated, we guarantee
it's populated, so don't need to worry about such a race with another
process populating our same LOCPATH.
This avoids the possibility that the bundle could be updated in place,
leading to LOCPATH existing but containing locales for the old version,
which needed to be tested for with code that was not race-free.
LOCPATH/buildid is still written and checked when cleaning up stale caches.
That is not actually necessary, except old versions of the standalone
bundle expect to see it, and this prevents them cleaning up the locale
cache of a new version. And still checking it prevents the new version
cleaning up the locale cache of the old version while the old version is
still in use.
Added explicit tests before creating LOCPATH and the base and buildid files.
The buildid file no longer needs to be updated every time, because it's
stable for the given LOCPATH directory.
And the base file actually did not need to be updated every time,
because the LOCPATH is derived from base, so if the bundle is moved
elsewhere, a different LOCPATH will be used.
Transitioning to this will mean that two git-annex builds that otherwise
have the same buildid -- the same git-annex md5sum -- will use different
LOCPATH values, but that's handled fine by the cache cleanup code, so at
most it will mean one extra generation of the locale files.
This seems to be the best way to deal with the race; if the first and
second runshell are running very close together, the first will generate
the locale directory, and a second test -d would still leave a race
window.
So these special remotes are always supported.
IIRC these build flags were added because the dep chains were a bit too
long, or perhaps because the libraries were not available in Debian stable,
or something like that. That was long ago, those reasons no longer apply,
and users get confused when builtin special remotes are not available, so
it seems best to remove the build flags now.
If this does cause a problem it can be reverted of course..

This includes making Build.Standalone run LinuxMkLibs or OSXMkLibs
rather than doing that separately. Which is groundwork for a later
optimisation.
Also it simplified the code some.
md5sum is part of busybox, so is probably available unless it were compiled
out. If md5sum (or cut for that matter) is not available, it will
still use the whole path to $base, otherwise hash it.
Of course it's possible for md5sum to be available sometimes and not others
on the same system; in such an event the locales would be built twice for
the same bundle. The cleanup code will delete both sets once that
version of the bundle is upgraded.
A warning message is unsatisfying. But erroring out is too hard a failure,
especially since it may well work fine if the user has enabled passwordless
ssh.
I did think about falling back to one ssh connection at a time in this
case, but it would have needed a rework of every ssh call, which
seems far overboard for such a niche problem. There's no single place where
git-annex runs ssh, so no one place that it could block a concurrent call
on a semaphore. And, even if it did fall back to one ssh connection at a
time, it seems to me that doing so without warning the user about the
problem just invites bug reports like "git-annex is ignoring my -J2 and
only doing one download at a time". So a warning is needed, and I suppose
is good enough.
~/.profile works for bash, but not all other login shells.
This setting PATH is a minor convenience for users, particuarly since
typing on android is so much harder. The usual linux standalone bundle
just expects the user to know how to add it to PATH. I don't want this
code to grow special cases for every possible login shell. So displaying a
message to the presumably minority who don't use bash seems like the best
choice.
Longer term, I'd hope termux gets some way to set an environment variable
for all login shells. Systems using PAM can, via ~/.pam_environment. Or
alternatively, add a git-annex package to termux, even if just an installer
package. I'd rather spend time on either of those than on making this minor
thing support more login shells.

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.

The bundled uname -o says Linux in termux; have runshell on Android
delete it so the termux one is used instead.
This fixes the webapp so it will enter Android mode.

* Added arm64 Linux standalone build. (No autobuilder yet.)
* Improved termux installation process.
Added git-annex-install.sh script to avoid user needing to type as much in
termux. The scope of this script is limited; runshell handles the rest.
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
others probably use the system Android /bin/sh, which could be old or
broken or not posix or whatever. Using termux sh to run the scripts is
better.

On android arm64, I saw the cp fail with "Bad system call", because proot
has not run yet. runshell only recently started using cp, and it's bundled
with git-annex, so this fixes a reversion.

It can be set to an empty string to use the system locales too. Of course
whether that will work depends on the amount of divergence.

linux standalone: Generate locale files in ~/.cache/git-annex/locales/ so
they're available even when the standalone tarball is installed in a
directory owned by root.
This avoids a full-on reference counting cleanup hell, by letting old
locale caches linger as long as the standalone bundle directory associated
with them is still around. Old ones get cleaned up.
In the case where the directory has a new bundle unpacked over top of it,
the old locale cache is invalidated and rebuilt. Of course, running
programs using that may get confused, but this was already the case, and
unpacking over top of a bundle is probably not a good idea anyhow.
To support that, added a buildid file, which only needs to be unique across
builds of git-annex with different libc versions. sha1sum of git-annex
seems good enough for that.
Removed debian/patches/standalone-no-LOCPATH as it's no longer
necessary.

runshell: Use proot when running on Android, to work around Android 8's
ill-advised seccomp filtering of system calls, including ones crucial for
reliable thread locking. (This will only work with termux's version of
proot.)
