I am not happy with the fragile pile of CPP boilerplate required to support
ghc back to 7.0, which git-annex still targets for both the android build
and the standalone build targeting old linux kernels. It makes me unlikely
to want to use Semigroup more in git-annex, because the benefit of the
abstraction is swamped by the ugliness. I actually considered ripping out
all the Semigroup instances, but some are needed to use
optparse-applicative.
The problem, I think, is they made this transaction on too fast a timeline.
(Although ironically, work on it started in 2015 or earlier!)
In particular, Debian oldstable is not out of security support, and it's
not possible to follow the simpler workarounds documented on the wiki and
have it build on oldstable (because the semigroups package in it is too
old).
I have only tested this build with ghc 8.2.2, not the newer and older
versions that branches of the CPP support. So there could be typoes, we'll
see.

Makes it allow writes, but not deletion of annexed content. Note that
securing pushes to the git repository is left up to the user.

* migrate: Fix bug in migration between eg SHA256 and SHA256E,
that caused the extension to be included in SHA256 keys,
and omitted from SHA256E keys.
(Bug introduced in version 6.20170214)
* migrate: Check for above bug when migrating from SHA256 to SHA256
(and same for SHA1 to SHA1 etc), and remove the extension that should
not be in the SHA256 key.
* fsck: Detect and warn when keys need an upgrade, either to fix up
from the above migrate bug, or to add missing size information
(a long ago transition), or because of a few other past key related
bugs.

Prevent haskell http-client from decompressing gzip files, so downloads of
such files works the same as it used to with wget and curl.
Explicitly setting accept-encoding to "identity" is probably not needed,
but that's what wget sends (curl does not send the header), and since
http-client is trying to be excessively smart, it seems we need to set
hAcceptEncoding to something to prevent it from inserting its own,
and this seems better than some hack like "".

* move: --force was accidentially enabling two unrelated behaviors
since 6.20180427. The older behavior, which has never been well
documented and seems almost entirely useless, has been removed.
* copy: --force no longer does anything.

This fixes a crash when a git submodule has a name starting with a dot.
Such a submodule might contain dotfiles that are intended to be used when
inside the view (since a dot-directory that's not a submodule was already
preserved when entering a view). So, rather than eliminating the submodule
from the view, its git ls-files --stage hash is copied over into the view.
dotfiles/dirs have their git ls-files --stage hashes similarly copied over
to the view. This is more efficient and simpler than the old method,
and also won't break if git ever adds a new type of tree item, like was
done with submodules.
Since the content of dotfiles in the working tree is no longer hashed
when entering a view, when there are unstaged modifications, they are
not included in the view branch. Entering the view branch still works,
but git checkout shows "M .dotfile", and git diff will show the unstaged
changes. This seems like an improvement over the old behavior.
Also made Command.View not delete empty directories that are submodules
when entering a view, while still deleting other empty directories.

* Display error message when http download fails.
There's nothing in the http-client library to nicely format a http
exception, so in some cases it has to fall back to using show on it.
Seems better than just saying "it failed" or only showing the http
status code.
* Avoid forward retry when 0 bytes were received.
forwardRetry was comparing Nothing to Just 0, and so thought there had
been progress made when 0 bytes were received.

The old git-annex Android app is now deprecated in favor of running
git-annex in termux. I suspect all or nearly all of these no longer apply.

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.)

Fix regression in last release that crashes when using --all or running
git-annex in a bare repository. May have also affected git-annex unused and
git-annex info.
Reversed the order of the (++) in Annex.Branch.files so --all will stream
lazily still when there are not a bunch of uncommitted journal files.
Added a todo to maybe improve this later.

Assistant: Integrate with Termux:Boot, so when it's installed, the

Added some tweaks to make git-annex work in termux on Android. The regular
arm standalone tarball now works in termux.
I guess the test for "$base/bin/git" is not really necessary, since it
tests for git-annex. Since that gets deleted on android, removed that test.
These are pretty hackish hacks, especially adding it to PATH. The goal is
to make it work well enough out of the box on Android.

As long as all code imports Utility.Aeson rather than Data.Aeson,
and no Strings that may contain utf-8 characters are used for eg, object
keys via T.pack, this is guaranteed to fix the problem everywhere that
git-annex generates json.
It's kind of annoying to need to wrap ToJSON with a ToJSON', especially
since every data type that has a ToJSON instance has to be ported over.
However, that only took 50 lines of code, which is worth it to ensure full
coverage. I initially tried an alternative approach of a newtype FileEncoded,
which had to be used everywhere a String was fed into aeson, and chasing
down all the sites would have been far too hard. Did consider creating an
intentionally overlapping instance ToJSON String, and letting ghc fail
to build anything that passed in a String, but am not sure that wouldn't
pollute some library that git-annex depends on that happens to use ToJSON
String internally.

move: Added --safe option, which makes move honor numcopies settings.
Also --unsafe enables the default behavior, anticipating that the

* For url downloads, git-annex now defaults to using a http library,
rather than wget or curl. But, if annex.web-options is set, it will
use curl. To use the .netrc file, run:
git config annex.web-options --netrc
* git-annex no longer uses wget (and wget is no longer shipped with
git-annex builds).
Note that curl is always run in silent mode, since the new API for
download has a MeterUpdate and doesn't make way for curl progress
output. It might be worth writing a parser for curl's progress output
to update the meter when using it, but I didn't bother with this edge
case for now.

Remote.S3 and Remote.Helper.Http both had similar code to sink a
http-conduit Response to a file; refactor out sinkResponseFile.
downloadC downloads an url to a file using http-conduit, and supports
resuming. Falls back to curl to handle urls that http-conduit does not
support. This is not used yet, but the goal is to replace download with
it.
git-annex.cabal: conduit-extra was not actually used for a long time,
remove the dep. conduit moves into the main dependency list, but since
http-conduit was already in there, and it depends on conduit, that's not
really adding a new build dep.

Enable HTTP connection reuse across multiple files, when git-annex
uses http-conduit. Before, a new Manager was created each time
Utility.Url used it. Now, a single Manager gets created the first time,
so connections are reused.
Doesn't help when external programs are used for url download,
but does speed up addurl --fast, fsck --from web, etc.
Testing fsck --fast --from web with 3 files, over high-latency
satellite internet, it sped up from 19.37s to 14.96s.

When adding a new version of a file, and annex.genmetadata is enabled,
don't copy the data metadata from the old version of the file, instead use
the mtime of the file. Rationalle being that the user has requested to
generate metadata and so would expect to get the new mtime into metadata.
Also, avoid warning about copying metadata when all the old metadata is
date metadata. Which was rather the harder part.

git annex testremote passes.
exportree not implemented yet, although the documentation talks about it,
since it will be the main way this remote will be used.
The adb push/pull progress is displayed for now; it would be better
to consume it and use it to update the git-annex progress bar.
