Release 2017.12

Quite a lot in this release. First, on the notable bugfix side,
we fixed an issue where background threads could remain alive
after an error was encountered during pulls. Particularly
for projects like flatpak that do multiple pulls in process, this
is an important fix.
PR: #1185

Another important change related to pulls is that libostree now
performs checksums when mirroring again.
The intent here was to speed up mirroring, but it led to a confusing security
story. Now it's easier to explain: for HTTP pulls we verify checksums
(and this can be disabled), for local filesystem pulls we don't,
(but it can be enabled). We've always verified checksums by
default when pulling from an archive repository into a non-archive.
PR: #1212

Anton Gerasimov contributed a change to the libcurl backend
to support PKCS#11 URIs, useful for storing certificates in a
hardware or software enclave.
PR: #1183

The schema for the experimental OstreeRepoFinderMount API to find OSTree
repos on removable media has changed incompatibly, so that the media doesn’t
need to contain two similar lists of refs. It will now look in .ostree/repos.d,
.ostree/repo, ostree/repo and var/lib/flatpak paths on removable media.
PR: #1179

Similarly, the experimental ostree_repo_resolve_keyring_for_collection() API
has changed to return an OstreeRemote containing the keyring, rather than just
the keyring, making it more generally useful.
PR: #1202

The bloom filter used when finding refs from remote peers has been fixed to
work correctly on 32-bit architectures (such as ARM). This doesn’t change the
bloom filter format, but will require bloom filters created on 32-bit
architectures to be regenerated in order for advertisements from those machines
to work.
PR: #1231

Repositories which have a collection ID set will now put their repository
metadata in an ostree-metadata ref when ostree summary --update is run, in
addition to putting it in the summary file. This is part of a plan to securely
allow unsigned summary files for peer-to-peer pulling of refs. This won’t
happen for repositories which don’t have a collection ID set, or if
--enable-experimental-api is not configured.
PR: #1158

A new ostree create-usb command has been added (if configured with
--enable-experimental-api) which can be used to put refs from repositories onto
removable media in a format which can be detected by OstreeRepoFinderMount.
For example, to allow easy sharing of flatpaks or OS updates between offline
machines.
PR: #1182

OstreeRepo has gained hash() and equal() methods, so it can now easily be used
in a hash table based on its device number and inode, rather than using its
path.
PR: #1179
PR: #1205

A minor bug was fixed in rofiles-fuse, which would cause files to be
created with random mode bits if called for O_RDONLY.
PR: #1200

For clients that use OstreeRepoDevInoCache, a bug was fixed which
caused libostree to ignore callbacks that allow modifying file modes,
ownership, and extended attributes.
PR: #1170

libostree now supports --with-crypto=gnutls. Like the OpenSSL
support, this is currently just checksums, but Jussi Laako
is driving this towards making the GPG
dependency optional and supporting other signature methods.
PR: #1189

In previous releases, libostree learned how to make hardlinks
for local pulls. But if we couldn't hardlink (e.g. the devices
were separate), the local pull code went through a much slower
generic path that included re-checksumming
objects. Now there's a copy/reflink fast path that uses
FICLONE/copy_file_range() directly if possible. This can be
substantially faster.
PR: #1197

ostree prune learned a new --only-branch option. This
can be a lot more convenient for release engineering tasks.
PR: #1127

As usual, more work was done to improve the testsuite. It should
now be able to better detect tmpfs/overlayfs environments. The
upstream CI now also runs tests in a non-overlayfs environment
for better coverage.
PR: #1217
PR: #1170
