The cabal file does not yet demand this version because it's not in Debian
yet and only affects use of certian broken http servers, but let's use it
when it's easily available.
using a blake2 variant optimised for 4-way CPUs
This had been deferred because the Debian package of cryptonite, and
possibly other builds, was broken for blake2bp, but I've confirmed #892855
is fixed.

Drop support for building with ghc older than 8.4.4, and with older
versions of serveral haskell libraries than will be included in Debian 10.
The only remaining version ifdefs in the entire code base are now a couple
for aws!
This commit should only be merged after the Debian 10 release.
And perhaps it will need to wait longer than that; it would make
backporting new versions of git-annex to Debian 9 (stretch) which
has been actively happening as recently as this year.

Reversion from commit 436f10771, CustomOutput was forcing quiet output
which overrode the json setting.
find happened to be the only command that uses CustomOutput and also
outputs json. (metadata --get does also use CustomOutput and --json does not
enable json output for that, which may be an oversight, but was already the
behavior before this regression.)
init: Fix a reversion in the last release that prevented automatically
generating and setting a description for the repository.
Seemed best to factor out uuidDescMapRaw that does not
have the default mempty descrition behavior.
I don't much like that behavior, but I know things depend on it.
One thing in particular is `git annex info` which lists the uuids and
descriptions; if the current repo has been initialized in some way that
means it does not have a description, it would not show up w/o that.
(Not only repos created due to this bug might lack that. For example a repo
that was marked dead and had --drop-dead delete its git-annex branch info,
and then came back from the dead would similarly not be in the uuid.log.
Also there have been other versions of git-annex that didn't set a default
description; for years there was no default description.)
When downloading an url and the destination file exists but is empty,
avoid using http range to resume, since a range "bytes=0-" is an unusual
edge case that it's best to avoid relying on working.
This is known to fix a case where importfeed downloaded a partial feed from
such a server. Since importfeed uses withTmpFile, the destination always exists
empty, so it would particularly tickle such problem servers. Resuming from 0
is otherwise possible, but unlikely.
get, move, copy, sync: When -J or annex.jobs has enabled concurrency,
checksum verification uses a separate job pool than is used for
downloads, to keep bandwidth saturated.
Not yet done for upload checksum verification, but that only affects
remotes on local disks.
Avoid a delay at startup when concurrency is enabled and there are
rsync or gcrypt special remotes, which was caused by git-annex
opening a ssh connection to the remote too early.
sshOptions makes a connection to the ssh server if one is not already open,
when concurrency is enabled. Avoid doing that at startup, when the remote
list is being built, but the remote may not be used at all.
Instead, rsync/gcrypt now runs sshOptions once per ssh connection to the
server. This should not be significant overhead since Remote.Git already
has the same overhead (as do Bup and Ddar).
The hoped for optimisation of CommandStart with -J did not materialize.
In fact, not runnign CommandStart in parallel is slower than -J3.
So, CommandStart are still run in parallel.
(The actual bad performance I've been seeing with -J in my big repo
has to do with building the remoteList.)
But, this is still progress toward making -J faster, because it gets rid
of the onlyActionOn roadblock in the way of making CommandCleanup jobs
run separate from CommandPerform jobs.
Added OnlyActionOn constructor for ActionItem which fixes the
onlyActionOn breakage in the last commit.
Made CustomOutput include an ActionItem, so even things using it can
specify OnlyActionOn.
In Command.Move and Command.Sync, there were CommandStarts that used
includeCommandAction, so output messages, which is no longer allowed.
Fixed by using startingCustomOutput, but that's still not quite right,
since it prevents message display for the includeCommandAction run
inside it too.
When running multiple concurrent actions, the cleanup phase is run in a
separate queue than the main action queue. This can make some commands
faster, because less time is spent on bookkeeping in between each file
transfer.
But as far as I can see, nothing will be sped up much by this yet, because
all the existing cleanup actions are very light-weight. This is just groundwork
for deferring checksum verification to cleanup time.
This change does mean that if the user expects -J2 will mean that they see no
more than 2 jobs running at a time, they may be surprised to see 4 in some
cases (if the cleanup actions are slow enough to notice).
It might also make sense to enable background cleanup without the -J,
for at least one cleanup action. Indeed, that's the behavior that -J1
has now. At some point in the future, it make make sense to make the
behavior with no -J the same as -J1. The only reason it's not currently
is that git-annex can build w/o concurrent-output, and also any bugs
in concurrent-output (such as perhaps misbehaving on non-VT100 compatible
terminals) are avoided by default by only using it when -J is used.
Add back support for ftp urls, which was disabled as part of the fix for
security hole CVE-2018-10857 (except for configurations which enabled curl
and bypassed public IP address restrictions). Now it will work if allowed
by annex.security.allowed-ip-addresses.
Renamed annex.security.allowed-http-addresses to
annex.security.allowed-ip-addresses because it is not really specific to
the http protocol, also limiting eg, git-annex's use of ftp and via
youtube-dl, several other protocols.
The old name for the config will still work.
If both old and new name are set, the new name will win.
When a remote is configured to be readonly, don't allow changing what's
exported to it.
This was missed in the original export remote implementation, but it makes
sense for a readonly export remote to not be allowed to change.
~/.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.

* init: When the repository already has a description, don't change it.
* describe: When run with no description parameter it used to set
the description to "", now it will error out.
Importing from a special remote honors its preferred content too; unwanted
files are not imported. But, some preferred content expressions can't be
checked before files are imported, and trying to import with such an
expression will fail.
Tested this with scenarios including changing the preferred content
expression and making sure merging the import didn't delete files that were
no longer wanted.
There was one minor inefficiency mentioned in the todo that I punted on.
Make the import have the previous import as a parent, so eg `git log --stat`
displays a useful diff.
Also a minor optimisation, only calculate the depth of the imported history
once.
This includes a note about how include= and exclude= match when exporting
a subtree. I don't know if the note is prominent enough, but the
behavior seems unsurprising enough.
Added the ability to run one job per CPU (core), by setting annex.jobs=cpus,
or using option --jobs=cpus or -Jcpus.
Built with future expansion in mind, including not defaulting matching on
Concurrency so more constructors can later be added, and using "cpu"
instead of "0".
Fixes bug that caused git-annex to fail to add a file when another
git-annex process cleaned up the temp directory it was using.
Solution is just to push withOtherTmp out to a higher level, so that
the whole ingest process can be completed inside it.
But in the assistant, that was not practical to do, since withOtherTmp runs
in the Annex monad and the assistant does not. Worked around by introducing
a separate temp directory that only the assistant uses for lockdown.
Since only one assistant can run at a time, it's easy to clean up that
directory of old cruft at startup.
Fix reversion in last release that caused wrong tree to be written to
remote tracking branch after an export of a subtree.
The invariant "commitsha should have the treesha as its tree"
was not met due to a bug. Guarantee it's met by catting the commitsha
to find its actual tree. A little bit slower, but this is not run often.
* Added mimeencoding= term to annex.largefiles expressions.
This is probably mostly useful to match non-text files with eg
"mimeencoding=binary"
* git-annex matchexpression: Added --mimeencoding option.
Switch listContents to being a proper CommandStart, so if it throws an
exception, it will be treated like any other command action that fails.
downloadImport apparently does not ever throw an exception,
and itself uses commandAction, so it can't be a CommandStart.
Fix bug that caused importing from a special remote to repeatedly download
unchanged files when multiple files in the remote have the same content.
Unfortunately, there's really no good way to remove a uniqueness constraint
from a sqlite database. The best that can be done is to make a new table
and copy the data over. But that would require using persistent's
migrations or raw sql, and I don't want to do either.
Instead, a sledgehammer approach: Renamed .git/annex/cid to
.git/annex/cids. When the new database doesn't exist, it will be populated
from the git-annex branch.
Noting deletes the old database. Don't want to delete it out from under
some long-running git-annex process that might be using it. It could
eventually be deleted. But this is such a new feature, probably few repos
have the database in any case.
