8fbf19c9f5 Make P2P API public (no longer experimental)
Currently the API that allows P2P operations (e.g. pulling an ostree ref
from a LAN or USB source) is hidden behind the configure flag
--enable-experimental-api. This commit makes the API public and makes
that flag essentially a no-op (leaving it in place in case we want to
use it again in the future). The P2P API has been tested over the last
several months and proven to work.

This means that since we're no longer using the "experimental" feature
flag, P2P builds of Flatpak will fail when using versions of OSTree from
this commit onwards, until Flatpak is patched in the near future. If you
want to build Flatpak < 0.11.8 with P2P enabled and link against OSTree
2018.6, you'll have to patch Flatpak.  However, since Flatpak won't yet
have a hard dependency on OSTree 2018.6, it needs a new way to determine
if the P2P API in OSTree is available, so this commit adds a "p2p"
feature flag. This way the feature set is more semantically correct than
if we had continued to use the "experimental" feature flag.

In addition to making the P2P API public, this commit makes the P2P unit
tests run by default, removes the f27-experimental CI instance that's no
longer needed, changes a few man pages to reflect the changes, and
updates the bash completion script to accept the new commands and
options.

6bf4b3e1d8 Add SPDX-License-Identifier to source files
SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.

Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
  text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
  environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
  license for their code is respected

f91acf5226 Add --with-crypto=gnutls
Introduce support for GnuTLS for computing cryptograpic
hashes, similar to the OpenSSL backend.  A reason to do
this is some distributors want to avoid GPLv3, and GPG
pulls that in.

A possible extension of using GnuTLS would be replacing the GPG signing
with `PKCS#7` signatures and `X.509` keys.

We also support `--with-crypto=openssl`, which has the same effect
as `--with-openssl`, and continues to be supported.

Changes by Colin Walters <walters@verbum.org>:

 - Drop libgcrypt option for now
 - Unify buildsystem on --with-crypto

f6ba20d9d6 build: Ensure all .sym files are distributed in tarballs
Since we’re using a custom variable for listing the .sym files,
automake’s magic support for automatically distributing all files in
conditionals doesn’t work, and the devel and experimental .sym files
were only being distributed if `make dist` was run on a source tree
which had been configured with --enable-experimental-api or not a
release flag.

Fix that by explicitly listing all the .sym files in EXTRA_DIST.

Specifically, this fixes the case of trying to compile with
--enable-experimental-api from a release tarball which was disted with
--disable-experimental-api.

e3d4eeacbc lib/repo-finder: Add Avahi based OstreeRepoFinder implementation
This is a more complex implementation of OstreeRepoFinder which resolves
ref names to remote URIs by looking for refs advertised by peers on the
local network using DNS-SD records and mDNS (Avahi). The idea is to
allow OS and app updates to be propagated over local networks, without
the internet.

It requires an OSTree server and code to generate the DNS-SD adverts in
order to be fully functional — support for this will be added
separately.

Unit tests are included.

ae335f24dc lib/repo-finder: Add mount based OstreeRepoFinder implementation
This is a basic implementation of OstreeRepoFinder which resolves ref
names to remote URIs by looking for them on any currently mounted
removable storage volumes. The idea is to support OS and app updates via

This bumps libostree’s maximum GLib dependency from 2.44 to 2.50 for
g_drive_is_removable(). If GLib 2.50 is not available, the call which
needs it will be omitted and the OstreeRepoFinderMount implementation
will scan all volumes (not just removable ones); this is a performance

Add an initial OstreeRepoFinder interface (but no implementations),
which will find remote URIs by ref names and collection IDs, the
combination of which is globally unique.

The new API is used in a new ostree_repo_find_updates() function, which
resolves a list of ref names to update into a set of remote URIs to pull
them from, which can be treated as mirrors. It is an attempt to
generalise resolution of the URIs to pull from, and to generalise
determination of the order and parallelisation which they should be
downloaded from in.

This is a type representing the tuple (collection ID, ref name), which is

It introduces the concept of a ‘collection’ which is a unique, curated

same key and validated by the same developer). Flathub might be a
collection, for example; or the set of OS refs coming from a particular
OS vendor.

a45dc0fd0b build-sys: Add "release build" flag, use for symbol versioning
I was trying to do a release and move the symbols from `-devel.sym` into
`-release.sym`, but it turns out that at least GNU binutils `ld` treats an empty
version script as a syntax error.  Fix this by adding a "release build"
flag, and only include `-devel` in non-release builds.

This would also make it easier to inject that flag into our `.pc` and
`ostree-version.h` and `ostree --version` metadata, but I didn't do that yet.

EDIT: Turns out a simpler fix is just to add an empty section. However I kept
this commit since it's a useful sanity check for whether we should include
`-devel.sym` in builds, and we may want to inject the metadata later.

30705889cb Switch to using a systemd generator for /var
If one wants to set up a mount for `/var` in `/etc/fstab`, it
won't be mounted since `ostree-prepare-root` set up a bind mount for
`/var` to `/sysroot/ostree/$stateroot/var`, and systemd will take
the already extant mount over what's in `/etc/fstab`.

There are a few options to fix this, but what I settled on is parsing
`/etc/fstab` in a generator (exactly like `systemd-fstab-generator` does),
except here we look for an explicit mount for `/var`, and if one *isn't* found,
synthesize the default ostree mount to the stateroot. Another nice property is
that if an admin creates a `var.mount` unit in `/etc` for example, that will
also override our mount.

Note that today ostree doesn't hard depend on systemd, so this behavior only
kicks in if we're built with systemd *and* libmount support (for parsing
`/etc/fstab`).  I didn't really test that case though.

Initially I started writing this as a "pure libc" program, but at one point
decided to use `libostree.so` to find the booted deployment. That didn't work
out because `/boot` wasn't necessarily mounted and hence we couldn't find the
bootloader config. A leftover artifact from this is that the generator code
calls into libostree via the "cmd private" infrastructure. But it's an easy way
to share code, and doesn't hurt.

fda4a47cae libostree: add versioning macros
OSTree currently provides no way to inspect the versioning
information at run time, being only available at compile
time through pkg-config.

This is a problem for e.g. Flatpak, that needs to check
whether the 'update-frequency' option is available. Checking
at compile time isn't great since it's not looking for new
symbols, but only if an optional feature is present.

This commit, then, adds a new header that is generated

361aa449fb libcurl backend
For rpm-ostree, we already link to libcurl indirectly via librepo, and
only having one HTTP library in process makes sense.

Further, libcurl is (I think) more popular in the embedded space.  It
also supports HTTP/2.0 today, which is a *very* nice to have for OSTree.

This seems to be working fairly well for me in my local testing, but it's
obviously brand new nontrivial code, so it's going to need some soak time.

The ugliest part of this is having to vendor in the soup-url code. With
Oxidation we could follow the path of Firefox and use the
[Servo URL parser](https://github.com/servo/rust-url).  Having to redo
cookie parsing also sucked, and that would also be a good oxidation target.

d894f609db oxidation: Add implementation of bupsplit in Rust
This is an initial drop of "oxidation", or adding implementation
of components in Rust.  The bupsplit code is a good target - no
dependencies, just computation.

Translation into Rust had a few twists -

 - The C code relies a lot on overflowing unsigned ints, and
   also on the C promotion rules for e.g. `uint8_t -> int32_t`
 - There were some odd loops that I introduced bugs in while
   translating...in particular, the function always returns `len`,
   but I mistakenly translated to `len+1`, resulting in an OOB
   read on the C side, which was hard to debug.

On the plus side, an off-by-one array indexing in the Rust code paniced nicely.

In practice, we'll need a lot more build infrastructure to make this work, such
as using `cargo vendor` when producing build artifacts for example. Also, Cargo
is yet another thing we need to cache.

Where do we go with this? Well, I think we should merge this, it's not a lot of
code. We can just have it be an alternative CI target. Should we do a lot more
right now? Probably not immediately, but I find the medium/long term prospects
pretty exciting!

51e4e3b364 libostree: Add g_autoptr() support for the public types
To avoid breaking the ostree users we hide the autoptr setup behind an
OSTREE_WITH_AUTOCLEANUPS variable. The variable is set to 0 by

Probably after some transition period, the variable will be set 1 by
default.

This is conditional on GLib >= 2.44.0 being available. It does not
bump ostree's dependency on GLib.

a5f703799f Make enum generation private by default, export stub symbol
When we added enum type generation, the generated symbols used
the `ostree_` prefix, and at the time that implied they were public.

So we started (if built with libsoup) exporting
`ostree_fetcher_config_flags_get_type`.

I think it's not worth confusing ABI checkers, so let's export the
dummy symbol forever, and switch enums to be private by default.

We should revisit this and also export some auto-generated enum
types for public enums, but that's a separate patch.

8894bb3949 deploy: Handle a read-only /boot
I'd like to encourage people to make OSTree-managed systems more
strictly read-only in multiple places.  Ideally everywhere is
read-only normally besides `/var/`, `/tmp/`, and `/run`.

`/boot` is a good example of something to make readonly.  Particularly
now that there's work on the `admin unlock` verb, we need to protect
the system better against things like `rpm -Uvh kernel.rpm` because
the RPM-packaged kernel won't understand how to do OSTree right.

In order to make this work of course, we *do* need to remount `/boot`
as writable when we're doing an upgrade that changes the kernel
configuration.  So the strategy is to detect whether it's read-only,
and if so, temporarily mount read-write, then remount read-only when
the upgrade is done.

We can generalize this in the future to also do `/etc` (and possibly
`/sysroot/ostree/` although that gets tricky).

One detail: In order to detect "is this path a mountpoint" is
nontrivial - I looked at copying the systemd code, but the right place
is to use `libmount` anyways.

16979cc5ed lib: Introduce versioned symbols
As rpm-ostree evolves, it keeps driving API additions to libostree.
This creates a relatively tight coupling.

However, if delivering via e.g. RPM, unless one manually remembers to
increment the `Requires:` in the spec file, it's possible for the two
to become desynchronized.

RPM handles versioned symbols and will ensure a dependency if the
application starts using a newer version.

To implement this, switch to `-fvisibility=hidden`, along with an
annotation in the header, and finally add a `.sym` file.

This matches what other projects like systemd and libvirt do.

Although rather than attempting to retroactively version symbols, glom
them all onto the current one.
