Because when git-annex lacks S3 version IDs for files stored in the bucket,
deleting them would cause data loss.
Also because git-annex is not able to download unversioned objects from a bucket
when versioning=yes.
This also prevents setting versioning=no. While that would perhaps be
possible to do safely, it would add complexity, and would mean that if
the user accidentially did enableremote versioning=no, they would not be
able to undo it.

Needs not yet released version 0.22 of aws library; with older versions
asks the user to configure the bucket versioning themselves.
Note that S3 endpoints that don't support versioning will cause putBucketVersioning
to throw an exception, so initremote will fail.

However, rsync still won't work with 64 bit git and
this is still not the documented way to install it.
So, if both 64 and 32 are installed, go with 32.
And if neither git can be found, default to 32.
* Switch to using .git/annex/othertmp for tmp files other than partial
downloads, and make stale files left in that directory when git-annex
is interrupted be cleaned up promptly by subsequent git-annex processes.
* The .git/annex/misctmp directory is no longer used and git-annex will
delete anything lingering in there after it's 1 week old.
Also, in Annex.Ingest, made the filename it uses in the tmp dir be
prefixed with "ingest-" to avoid potentially using a filename used by
some other code.
This will speed up the common case where a Key is deserialized from
disk, but is then serialized to build eg, the path to the annex object.
It means that every place a Key has any of its fields changed, the cache
has to be dropped. I've grepped and found them all. But, it would be
better to avoid that gotcha somehow..
A keyName could contain "/", though this is unlikely and certianly only
ever could happen with WORM keys.
The change to addunused to escape that is no problem at all.
The change to VariantFile to escape it means that different versions of
git-annex could resolve a merge conflict differently in this case, which
is unfortunate. There would be different .variant files used, so the two
resolutions would themselves merge together without additional
conflicts, but the user would have to clean up the extra .variant
files.
Not likely to be any speed gain here, but this completes porting every
log file over.
And, it let me get rid of code copied from ghc and modified, so
simplifying the licensing.
This preserves the workaround for the old bug that caused NoUUID items
to be stored in the log, prefixing log lines with " ". It's now handled
implicitly, by using takeWhile1 (/= ' ') to get the uuid.
There is a behavior change from the old parser, which split the value
into words and then recombined it. That meant that "foo bar" and "foo\tbar"
came out as "foo bar". That behavior was not documented, and seems
surprising; it meant that after a git-annex describe here "foo bar",
you wouldn't get that same string back out when git-annex displayed repo
descriptions.
Otoh, some other parsers relied on the old behavior, and the attoparsec
rewrites had to deal with the issue themselves...
For group.log, there are some edge cases around the user providing a
group name with a leading or trailing space. The old parser would ignore
such excess whitespace. The new parser does too, because the alternative
is to refuse to parse something like " group1 group2 " due to excess
whitespace, which would be even more confusing behavior.
The only git-annex branch log file that is not converted to attoparsec
and bytestring-builder now is transitions.log.
Mostly didn't push the ByteStrings down very deep, but all of these log
files are not written to frequently at all, so slight remaining
innefficiency doesn't matter.
In Logs.UUID, removed the fixBadUUID code that cleaned up after a bug in
git-annex versions 3.20111105-3.20111110. In the unlikely event that a repo was
last touched by that ancient git-annex version, the descriptions of remotes
would appear missing when used with this version of git-annex. That is such minor
breakage, and so unlikely to still be a problem for any repos, that it was not
worth forward-porting that code to ByteString.
Tested on an older ghc by enabling MonadFailDesugaring globally.
In TransferQueue, the lack of a MonadFail for STM exposed what would
normally be a bug in the pattern matching, although in this case an
earlier check that the queue was not empty avoided a pattern match
failure.
This is not as efficient as using ByteStrings throughout, but converting
the String to ByteString is actually significantly faster than the old
parser.

There is a small behavior change from the old parsePOSIXTime,
which accepted any amount of trailing whitespace after the timestamp.
That behavior was not documented, and it doesn't seem anything relied on it.
It used to display the "bad feed content" message indicating there were no
enclosures found, which was misleading when the http request for the feed
failed.

downloadUrl uses meteredFile, which sets up one progress meter,
and Remote.Web also uses metered, so two progress meters are displayed for
the same download.
Reversion introduced with the http-conduit switch in
c34152777b -- I don't know why the extra
call to metered was added there.
When -J is not used, the extra progress meter didn't display,
but an extra blank line did get output, which is also fixed.

init: When --version=5 is passed on a crippled filesystem, use a v5 direct
mode repo as requested, rather than upgrading to v7 adjusted unlocked.
Fixed test suite on crippled filesystems, making it request --version=5
to test direct mode.
Deleting directories is one of the great unsolved problems of CS, thanks to
abominations like NFS lock files and Windows and races with other processes
cleaning up after themselves in the background. The gpg test harness
sometimes failed to delete its temp directory on NFS. Avoid the problem
class by not deleting it at all, and putting it inside the tmp repo being
tested. The test suite's more robust (and/or nonsensical) workarounds for
deleting its test dir will thus be used, hopefully avoiding the problem
until an OS finds a new way to violate POSIX and the laws of nature.
Note that this means that the .gnupg directory will be on whatever
filesystem the test suite is being run on, which may be a lesser quality
filesystem than gpg is really expecting. Gpg does not seem to need to
write sockets etc to there so this seems ok. The only known problem is
that if the filesystem forces a directory mode like 777, gpg will warn
about unsafe home directory perms, but it still works.
This fixes a bug with the numcopies counting when using sync --content.
It did not always pass the local repo uuid to handleDropsFrom, and so the
numcopies counting was off by one, and unwanted local content would only be
dropped when there were numcopies+1 remote copies.
Also, support dropping local content that has reached an
exporttree remote that is not untrusted (currently only S3 remotes
with versioning).
* Fix bug upgrading from direct mode to v7: when files in the repository
were already committed as v7 unlocked files elsewhere, and the
content was present in the direct mode repository, the annexed files
got their full content checked into git.
* Fix bug that caused v7 unlocked files in a direct mode repository
to get locked when committing.

When a file was already unlocked, but the annex object was present, the
upgrade process populated the unlocked file, but neglected to update the
index.

No deprecation warning at run time, just one on the man page.
One thing findref remains able to do that find cannot is to run in a bare
repo. Find was made to refuse to run in a bare repo because it seemed
confusing for it to not list any files ever in that situation. It would be
better for find --branch to work in a bare repo but not without --branch
but I don't currently have a way to do that.
Probably a better solution would be to make git-annex in a bare repo
default to --branch master or something like that instead of --all.

* findref: Support file matching options: --include, --exclude,
--want-get, --want-drop, --largerthan, --smallerthan, --accessedwithin
* Commands supporting --branch now apply file matching options --include,
--exclude, --want-get, --want-drop to filenames from the branch.
Previously, combining --branch with those would fail to match anything.
* add, import, findref: Support --time-limit.

When public access is used for the remote, it complained that the user
needed to set creds to use it, which was just wrong.
When creds were being used, it fell back from trying to use the version ID
to just accessing the key in the bucket, which was ok for non-export
remotes, but wrong for buckets.
In both cases, display a hopefully useful warning.
This should only come up when an existing S3 remote has been exported
to, and then later versioning was enabled.
Note that it would perhaps be possible to fall back from trying to use
retrieveKeyFile when it fails and instead use retrieveKeyFileFromExport,
which may work when S3 version ID is missing. But there are problems
with that approach; how to tell when retrieveKeyFile has failed due to this
rather than a network problem etc? Anyway, that approach would only work
until the file in the export got overwritten, and then it would no
longer be accessible. And with versioning enabled, the user wants old
versions of objects to remain accessible, so it seems better to warn
about the problem as soon as possible, so they can go back and add S3
version IDs.
This work is supported by the NIH-funded NICEMAN (ReproNim TR&D3) project.
Note that it does not prevent storing p2p access tokens or multicast
encryption keys, since those are not cached; the previous commit
established the distinction.
How well this works depends on how often getRemoteCredPair is called and
how expensive it is. In some cases setting this will result in an annoying
number of gpg password prompts and/or slowdowns due to reading creds
from the git-annex branch and decrypting, which could be improved by calling
getRemoteCredPair less often.

And added stack-lts-9.9.yaml to support old versions of stack.
The i386 ancient autobuilder needs stack-lts-9.9.yaml; the OSX autobuilder
may also use it for a while, and it's needed to build on eg debian stable.
That didn't actually happen, newer lts like that one are not supported
by the version of stack in Debian stable, used for the i386-ancient
autobuild, and generally I want git-annex to be buildable on stable
releases of linux distros etc. So stack.yaml is going to be stuck on old
versions for some time until some years after stack stops breaking backwards
compatability.
