* 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 reverts commit 4536c93bb2.
That broke Read/Show of a Key, and unfortunately Key is read in at least
one place; the GitAnnexDistribution data type.
It would be worth bringing this optimisation back, but it would need
either a custom Read/Show instance that preserves back-compat, or
wrapping Key in a data type that contains the serialization, or changing
how GitAnnexDistribution is serialized.
Also, the Eq instance would need to compare keys with and without a
cached seralization the same.
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..
What these generate is not really suitable to be used as a filename,
which is why keyFile and fileKey further escape it. These are just
serializing Keys.
Also removed a quickcheck test that was very unlikely to test anything
useful, since it relied on random chance creating something that looks
like a serialized key. The other test is sufficient for testing what
that was intended to test anyway.
This should make == comparison of UUIDs somewhat faster, and perhaps a
few other operations around maps of UUIDs etc.
FromUUID/ToUUID are used to convert String, which is still used for all
IO of UUIDs. Eventually the hope is those instances can be removed,
and all git-annex branch log files etc use ByteString throughout, for a
real speed improvement.
Note the use of fromRawFilePath / toRawFilePath -- while a UUID usually
contains only alphanumerics and so could be treated as ascii, it's
conceivable that some git-annex repository has been initialized using
a UUID that is not only not a canonical UUID, but contains high unicode
or invalid unicode. Using the filesystem encoding avoids any problems
with such a thing. However, a NUL in a UUID seems extremely unlikely,
so I didn't use encodeBS / decodeBS to avoid their extra overhead in
handling NULs.
The Read/Show instance for UUID luckily serializes the same way for
ByteString as it did for String.
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.

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.

which is the tree last exported to the remote. During an export conflict,
multiple values will be listed.

Removed undocumented special case in handling of a CHECKURL-MULTI response
with only a single file listed. Rather than ignoring the url that was in
the response, use it. This allows external special remotes that want to
provide some better url to do so, although I don't entirely agree with
using CHECKURL-MULTI to accomplish that. I'm more of the feeling that an
undocumented special case that throws data away is just not a good idea.
This could in theory break some external special remote program that relied
on the current behavior, but its seems unlikely that it would because such
a program must already handle the multiple url case, unless it only ever
provides a single url response to CHECKURL-MULTI.
Make addurl --file work with a single item CHECKURL-MULTI response.
It already did for external special remotes due to the special case,
but now it also will for builtin ones like the BitTorrent special remote.

* rmurl: Fix a case where removing the last url left git-annex thinking
content was still present in the web special remote.
* SETURLPRESENT, SETURIPRESENT, SETURLMISSING, and SETURIMISSING
used to update the presence information of the external special remote
that called them; this was not documented behavior and is no longer done.
Done by making setUrlPresent and setUrlMissing only update presence info
for the web, and only when the url is a web url. See the comment for
reasoning about why that's the right thing to do.
In AddUrl, had to make it update location tracking, to handle the
non-web-url case.

The error message displayed used to only come from curl/wget and perhaps
was clearer than the one displayed now that http-client is used. In any
case, it does make sense to hide it because git-annex prints its own
warning message.

Same goal as b18fb1e343 but without
breaking backwards compatability. Just return IO exceptions when running
the P2P protocol, so that git-annex-shell can detect eof and avoid the
ugly message.

When the publicurl has been set to an url that does not end with a slash,
we need to add one in between it and the rest of the url.
As far as I can see, git-annex does not default to such publicurls; it's
careful to end them with slashes. But this was observed in the wild, and
there may be documentation that doesn't include the slash. And it's an easy
mistake to make in any case.

S3: Multipart uploads are now only supported when git-annex is built
with aws-0.16.0 or later, as earlier versions of the library don't
support versioning with multipart uploads.
This will affect the android build, and debian stable also has a too old
aws to support both features at the same time.

Makes git annex whereis display the versionId urls.
And, when a s3 remote is enabled without creds, git-annex will use the
versionId urls to access its contents.
This commit was sponsored by Fernando Jimenez on Patreon.
Since the same key can be stored in a versioned S3 bucket multiple times
with different version IDs, this allows tracking them all. Not currently
needed, but if we ever want to drop from a versioned S3 bucket, we'll
need to know them all.

Have to store the S3 object along with the version ID, so retrieval can
use the same object.
This commit was supported by the NSF-funded DataLad project.
Only done when versioning=yes is configured. It could always do it when
S3 sends back a version id, but there may be buckets that have
versioning enabled by accident, so it seemed better to honor the
configuration.
S3's docs say version IDs are "randomly generated", so presumably
storing the same content twice gets two different ones not the same one.
So I considered storing a list of version IDs for a key. That would
allow removing the key completely. But.. The way Logs.RemoteState works,
when there are multiple writers, the last writer wins. So storing a list
would need a different log format that merges, which seemed overkill to support
removing a key from an append-only remote.
Note that Logs.RemoteState for S3 is now dedicated to version IDs.
If something else needs to be stored, a new log will be needed to do it.

Make exporttree=yes remotes that are appendonly not be untrusted, and not force
verification of content, since the usual concerns about losing data when an
export is updated by someone else don't apply.
Note that all the remote operations on keys are left as usual for
appendonly export remotes, except for storing content.

Fix reversion introduced in version 6.20180316 that caused git-annex to
stop processing files when unable to contact a ssh remote.
The bug was not in any of the changed lines, but this one in inAnnex:
P2PHelper.checkpresent (Ssh.runProto rmt connpool (cantCheck rmt) fallback) key
cantCheck throws an exception, but that parameter to runProto expects a
value, which it returns. So, inAnnex is returning a Bool containing an
exception. This defeats the usual checks for checkPresent throwing an
exception, crashing git-annex.
Fixed by making runProto take an `Annex a` instead of an `a`, so
passing cantCheck to it doesn't nest exceptions.
