tryGitConfigRead may run ensureInitialized first, but when checkuuid = false,
that is skipped. So, make sure it's run before all onLocal actions.
ensureInitialized is inexpensive, so the extra call by tryGitConfigRead
is not a big deal. But since it was easy to do, I made it only be run
once by all calls to onLocal.
A few calls to onLocal didn't call ensureInitialized before. Notably,
the checkPresent action didn't, and does now.
That means that there's a guarantee that any necessary repo upgrades
will be run before the checkPresent action runs in the repo. Which is
important especially for the direct mode conversion, because without
that upgrade, the checkPresent action would need to support direct mode
still. Now I can remove the last bits of direct mode support in
Annex.Content without worrying that it will break accessing remotes
that have not been upgraded.
This does necessarily mean that checkPresent needs to write to the disk
when performing such a repo upgrade. The other remote actions already
did, so retrieval from a readonly remote that needed to be upgraded would
fail. Having checkPresent also fail doesn't seem like a large reversion,
especially since it already failed in the default case when checkuuid = true.
Prompted by the test suite on windows failing to with "export foo failed"
and no information about what went wrong.
Note that only storeExportWithContentIdentifier has been converted.
storeExport still returns a Bool and so exceptions may be hidden.
However, storeExportWithContentIdentifier has many more failure modes,
since it needs to avoid overwriting modified files. So it's more
important it have better error display.
The test suite was intermittently failing with rsync complaining it
could not write to dest.

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1207) [sender=3.1.3]
It seems that the first rsync actually transferred the file, but then for some
reason git-annex thinks it failed, so it retries. The second rsync then fails
because the first rsync copied the file mode over and so the file is not
writable now.
So, this fixes that problem, but leaves open the question of why git-annex
would think rsync failed when it wrote the file and didn't output any
error message. Possibly a bug in rsyncProgress that either hides an
error message, or somehow makes rsync unhappy?
Using Logs.RemoteState for this means that if the same key gets uploaded
twice to a git-lfs remote, but somehow has different content the two
times (eg it's an URL key with non-stable content), the sha256/size of
the newer content uploaded will overwrite what was remembered before. That
seems ok; it just means that git-annex will request the newer version of
the content when downloading from git-lfs.
It will remember the sha256 and size if both are not known, or if only
the sha256 is not known but the size is known, it only remembers the
sha256, to avoid wasting space on the size. I did not add special case
for when the sha256 is known and the size is not, because it's been a
long time since git-annex created SHA256 keys without a size.
(See doc/upgrades/SHA_size.mdwn)
The protocol design allows the server to respond with some other object;
if a server for some reason a server did that, it would not be right for
git-annex to download its content. I don't think it would be a security
hole, since git-annex is downloading a specific key and will verify the
key's content. Seems like a good idea to belt-and-suspenders test for
such a misuse of the protocol.
This is a special remote and a git remote at the same time; git can pull
and push to it and git-annex can use it as a special remote.
Remote.Git has to check if it's configured as a git-lfs special remote
and sets it up as one if so.
Object methods not implemented yet.
In 40ecf58d4b I changed the license of code I
wrote from GPL to AGPL. But, two files containing code I wrote combined
with code by others were updated to say their license is AGPL, while in
fact part of it was (the code I wrote) but part remained under the original
license (the code written by others).
Remote/Ddar.hs is now changed entirely back to GPL 3.
Annex/DirHashes.hs stays AGPL, but I broke out Utility/MD5.hs with the code
not written by me, and corrected its license statement to GPL-2, which
is the actual version of the GPL included with the code in its original
distribution at http://www.cs.ox.ac.uk/people/ian.lynagh/md5/
Improved probing when CoW copies can be made between files on the same
drive. Now supports CoW between BTRFS subvolumes. And, falls back to rsync
instead of using cp when CoW won't work, eg copies between repos on the
same EXT4 filesystem.
Rather than trying cp --reflink=always for each file copied to a remote,
it's tried once and if it fails it falls back to using rsync thereafter
for the lifetime of the Remote object. That avoids overhead of calling cp
which while small, will add up over a large number of files.

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.

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).
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.
* 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.
As well as adding the necessary methods, a few other changes to the adb
remote:
* Use ".annextmp" extension for temp files, to avoid conflict with other
temp files.
* Stop using "echo $?" to get exit status of command inside adb.
There were two problems; first the "echo" just before it meant it was
always 0! And secondly, it seems kind of random on my phone whether it's
1 or 0, not dependant on whether the command seems to have succeeded.
Unfortunately, "port" has to be set by default, or the old git-annex
will crash when trying to enable the S3 remote.
So, when protocol=https is specified, it needs to override port=80,
since it may be a default setting.
protocol=https implies port=443 and
port=443 implies protocol=https
-- this was necessary because the existing configs set port=443, but
with a protocol setting, users will naturally want to use it, and then
there's no need for them to supply the default https port. So we keep
back-compat, add a nicer way to enable https, and also add support for
non-standard https ports.
