5f0f063a7a documented it as being
configured automatically, but the code never did that. Rather than try
to hard-code whatever urls amazon uses for its buckets, it seems better
to ask the user to find the url and set it.
Security fix! Allowing any schemes, particularly file: and
possibly others like scp: allowed file exfiltration by anyone who had
write access to the git repository, since they could add an annexed file
using such an url, or using an url that redirected to such an url,
and wait for the victim to get it into their repository and send them a copy.
* Added annex.security.allowed-url-schemes setting, which defaults
to only allowing http and https URLs. Note especially that file:/
is no longer enabled by default.
* Removed annex.web-download-command, since its interface does not allow
supporting annex.security.allowed-url-schemes across redirects.
If you used this setting, you may want to instead use annex.web-options
to pass options to curl.
With annex.web-download-command removed, nearly all url accesses in
git-annex are made via Utility.Url via http-client or curl. http-client
only supports http and https, so no problem there.
(Disabling one and not the other is not implemented.)
Used curl --proto to limit the allowed url schemes.
Note that this will cause git annex fsck --from web to mark files using
a disallowed url scheme as not being present in the web. That seems
acceptable; fsck --from web also does that when a web server is not available.
youtube-dl already disabled file: itself (probably for similar
reasons). The scheme check was also added to youtube-dl urls for
completeness, although that check won't catch any redirects it might
follow. But youtube-dl goes off and does its own thing with other
protocols anyway, so that's fine.
Special remotes that support other domain-specific url schemes are not
affected by this change. In the bittorrent remote, aria2c can still
download magnet: links. The download of the .torrent file is
otherwise now limited by annex.security.allowed-url-schemes.
This does not address any external special remotes that might download
an url themselves. Current thinking is all external special remotes will
need to be audited for this problem, although many of them will use
http libraries that only support http and not curl's menagarie.
The related problem of accessing private localhost and LAN urls is not
addressed by this commit.

External special remotes can now add info to `git annex info $remote`, by
replying to the GETINFO message.
Had to generalize some helpers to allow consuming multiple messages from
the remote.
The code added to Remote/* here is AGPL licensed, thus changed the license
of the files.

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.

Renaming is not supported; it might be possible to use --fuzzy to get rsync
to notice the file is being renamed, but that is a bit ..fuzzy.
On the other hand, interrupted transfers of an exported file are resumed,
since rsync is great at that. Had to adjust the exporttree docs, which
said interrupted transfers would restart.
Note that remove no longer makes the empty directory dummy, instead
sending the top-level empty directory. This works just as well and I
noticed the dummy was unncessary when refactoring it into removeGeneric.
Verified that behavior of remove is not changed, and git annex
testremote does pass.

Not yet called by Command.Export.
WebDAV needs this to clean up empty collections. Also, example.sh turned
out to not be cleaning up directories when removing content
from them, so it made sense for it to use this.
Remote.Directory did not need it, and since its cleanup method for empty
directories is more efficient than what Command.Export will need to do
to find empty directories, it uses Nothing so that extra work can be
avoided.

This basically works, but there's a bug when renaming a file that leaves
a .git-annex-temp-content-key file in the webdav store, that never gets
cleaned up.
Also, exporting files with spaces to box.com seems to fail; perhaps it
does not support it?

It opens a http connection per file exported, but then so does git
annex copy --to s3.
Decided not to munge exported filenames for IA. Too large a chance of
the munging having confusing results. Instead, export of files not
supported by IA, eg with spaces in their name, will fail.

* Only export to remotes that were initialized to support it.
* Prevent storing key/value on export remotes.
* Prevent enabling exporttree=yes and encryption in the same remote.
SetupStage Enable was changed to take the old RemoteConfig.
This allowed only setting exporttree when initially setting up a
remote, and not configuring it later after stuff might already be stored
in the remote.
Went with =yes rather than =true for consistency with other parts of
git-annex. Changed docs accordingly.

Fix the external special remotes git-annex-remote-ipfs,
git-annex-remote-torrent and the example.sh template to correctly support
filenames with spaces.

I've long considered the XMPP support in git-annex a wart.
It's nice to remove it.
(This also removes the NetMessager, which was only used for XMPP, and the
daemonstatus's desynced list (likewise).)
Existing XMPP remotes should be ignored by git-annex.

* S3: Support the special case endpoint needed for the cn-north-1 region.
* Webapp: Don't list the Frankfurt region, as this (and some other new
regions) need V4 authorization which the aws library does not yet use.

* Fix failure to build with aws-0.13.0.
* When built with aws-0.13.0, the S3 special remote can be used to create
google nearline buckets, by setting storageclass=NEARLINE.
Added support for storageclass=STANDARD_IA to use Amazon's
new Infrequently Accessed storage.
Also allows using storageclass=NEARLINE to use Google's NearLine storage.
The necessary changes to aws to support this are in
https://github.com/aristidb/aws/pull/176
In my tests, this has to be set when uploading a file to the bucket
and then the file can be accessed using the bucketname.s3.amazonaws.com
url.
Setting it when creating the bucket didn't seem to make the whole bucket
public, or allow accessing files stored in it. But I have gone ahead and
also sent it when creating the bucket just in case that is needed in some
case.
Useful for things like ipfs that don't use regular urls.
An external special remote can add a regular url to a key, and then
git-annex get will download it from the web. But for ipfs, we want to
instead tell git-annex that the uri uses OtherDownloader. Before this
change, the external special remote protocol lacked a way to do that.
Doesn't really seem worth making it work; addurl --fast can be used to
get a tree of files in the torrent and then the user can rm the ones they
don't want.
addurl behavior change: When downloading an url ending in .torrent,
it will download files from bittorrent, instead of the old behavior
of adding the torrent file to the repository.
Added Recommends on aria2 and bittornado | bittorrent.

When uploading the last part of a file, which was 640229 bytes, S3 rejected
that part: "Your proposed upload is smaller than the minimum allowed size"
I don't know what the minimum is, but the fix is just to include the last
part into the previous part. Since this can result in a part that's
double-sized, use half-sized parts normally.
I'm a little stuck on getting the list of etags of the parts.
This seems to require taking the md5 of each part locally,
which doesn't get along well with lazily streaming in the part from the
file. It would need to read the file twice, or lose laziness and buffer a
whole part -- but parts might be quite large.
This seems to be a problem with the API provided; S3 is supposed to return
an etag, but that is not exposed. I have filed a bug:
