This allows specifying gpgpath as list of
paths that can point to a file or a directory. If a directory path
is given, paths to all regular files in the directory are added
to the remote as gpg ascii keys. If the path is not a directory,
the file is directly added (whether regular file, empty - errors
will be reported later when verifying gpg keys e.g. when pulling).
Adding the gpgkeypath property looks like:
ostree --repo=repo remote add --set=gpgpath="/path/key1.asc,/path/keys.d" R1 https://example.com/some/remote/ostree/repoCloses#773Closes: #1773

This renames a config key to make its semantics more obvious. Despite
what the commit message says, it only applies when a set of repo finders
is not specified (either on the command line or in a library API call).
This also renames the corresponding ostree_repo_get function. We can do
this since it hasn't been released yet.

This commit disables searching on the local network for refs, unless
explicitly requested by the user either by changing the value of the
"core.repo-finders" config option, or by passing an OstreeRepoFinderAvahi to
ostree_repo_find_remotes_async() / ostree_repo_finder_resolve_async(),
or by specifying "lan" in the --finders option of the find-remotes
command.
The primary reason for this is that ostree_repo_find_remotes_async()
takes about 40% longer to complete with the LAN finder enabled, and that
API is used widely (e.g. in every flatpak operation). It's also probable
that some users don't want ostree doing potentially unexpected traffic
on the local network, even though everything pulled from a peer is GPG
verified.
Flathub will soon deploy collection IDs to everyone[1] so these code
paths will soon see a lot more use and that's why this change is being
made now.
Endless is the only potential user of the LAN updates feature, and we
can revert this patch on our fork of ostree. For it to be used outside
Endless OS we will need to upstream eos-updater-avahi and
eos-update-server into ostree.

Currently libostree essentially has two modes when it's pulling refs:
the "legacy" code paths pull only from the Internet, and the code paths
that are aware of collection IDs try to pull from the Internet, the
local network, and mounted filesystems (such as USB drives). The problem
is that while we eventually want to migrate everyone to using collection
IDs, we don't want to force checking LAN and USB sources if the user
just wants to pull from the Internet, since the LAN/USB code paths can
have privacy[1], security[2], and performance[3] implications.
So this commit implements a new repo config option called "repo-finders"
which can be configured to, for example, "config;lan;mount;" to check
all three sources or "config;mount;" to disable searching the LAN. The
set of values mirror those used for the --finders option of the
find-remotes command. This configuration affects pulls in three places:
1. the ostree_repo_find_remotes_async() API, regardless of whether or
not the user of the API provided a list of OstreeRepoFinders
2. the ostree_repo_finder_resolve_async() /
ostree_repo_finder_resolve_all_async() API
3. the find-remotes command
This feature is especially important right now since we soon want to
have Flathub publish a metadata key which will have Flatpak clients
update the remote config to add a collection ID.[4]
This effectively fixes https://github.com/flatpak/flatpak/issues/1863
but I'll patch Flatpak too, so it doesn't pass finders to libostree only
to then have them be removed.

[3] Based on how long the "ostree find-remotes" command takes to
complete, having the LAN finder enabled slows down that step of the
pull process by about 40%. See also

This commit removes the recommendation in the create-usb man page for
the user to update the summary in the source repo before using the
create-usb command. I'm not sure where I got the idea that create-usb
depends on a summary in the source repo. I went back to the first commit
that introduced the create-usb command and even using that a summary
isn't required, so it seems unlikely that this changed recently.
This is good news because the exclusive lock that's taken for summary
updates has been causing problems on Endless (due to other processes
having a lock for the duration of the 30 second acquire time out
period).
Closes: #1746
Approved by: cgwalters
Currently on Endless OS, the OSTree ref for the operating system is
something like os/eos/amd64/eos3, so that's what gets passed to `ostree
create-usb` when copying the OS to a USB drive (for offline updates).
However, when eos-updater checks for updates it pulls the metadata for a
candidate commit and in so doing updates that eos3 ref to point to the
partial commit being examined as a potential update rather than the
deployed commit. This causes `ostree create-usb` to fail with an error
like "No such metadata object
7fb045cb2d1f1f3a81bfc157c6128ff443eb56350315b9536bdb56aee0659863.dirtree".
OSTree creates deployment refs that look like "ostree/1/1/0" to maintain
a pointer to the deployed commit, but create-usb can't use these because
it shows up in the summary as just a ref, not a collection-ref.
So this commit adds a --commit option to the create-usb command, so we
can use the appropriate ref but copy the deployed commit rather than a
(potentially partial) update commit.

0 is not a valid value (the units are required), and 1MB is taken to
mean 1048576 bytes, not 1000000 bytes (unlike other human-readable sizes
in libostree, which are formatted by g_format_size(), and hence use
power-of-10 units). It's probably a bit late to change this latter
point, but the documentation should mention it.
Define 'MB' etc. more precisely; include the byte counts in the
examples; and improve the formatting of the min-free-space-* paragraphs.

Now that we have `auto-update-summary`, there is no point in having
`commit-update-summary`. The latter also only had an effect through
the `commit` CLI command, whereas the former is embedded directly in
libostree.
There is one corner case that slips through: `commit` would update the
summary file even if orphan commits were created, which we no longer do
here. I can't imagine anyone relying on this, so it seems safe to drop.

Mildly bikeshed, though I find the name `auto-update-summary` to be
easier to grok than `change-update-summary`. I think it's because it can
be read as "verb-verb-noun" rather than "noun-verb-noun".
Closes: #1693
Approved by: mwleeds
This commits adds and implements a boolean repo config option called
"change-update-summary" which updates the summary file every time a ref
changes (additions, updates, and deletions).
The main impetus for this feature is that the `ostree create-usb` and
`flatpak create-usb` commands depend on the repo summary being up to
date. On the command line you can work around this by asking the user to
run `ostree summary --update` but in the case of GNOME Software calling
out to `flatpak create-usb` this wouldn't work because it's running as a
user and the repo is owned by root. That strategy also means flatpak
can't update the repo metadata refs for fear of invalidating the
summary.
Another use case for this relates to LAN updates. Specifically, the
component of eos-updater that generates DNS-SD records advertising ostree
refs depends on the repo summary being up to date.
Since ostree_repo_regenerate_summary() now takes an exclusive lock, this
should be safe to enable. However it's not enabled by default because of
the performance cost, and because it's more useful on clients than
servers (which likely have another mechanism for updating the summary).

Now that it's possible to have both min-free-space-size and
min-free-space-percent set in a repo config, update the docs to make
the behavior clear in that case.
Closes: #1687
Approved by: jlebon
Previously, we would error out if both of the options were mentioned
in the config file (even if one of them is disabled with 0). There
were few suggestions that this behavior was not quite right.
Therefore, instead of throwing error and exiting, it's preferred to
warn the user. Hence, the solution that worked out is:
* Allow both options to exist simulateneously
* Check each config's value and decide:
* If both are present and are non-zero, warn the user. Also, prefer
to use min-free-space-size over the another.
* If both are absent, then use -percent=3% as fallback
* Every other case is valid hence, no warning

Similar to min-free-space-percent but it supports specific sizes
(in MB, GB or TB). Also, making min-free-space-percent and -size
mutually exclusive.
min-free-space-percent does not give a fine tuning of the free disk
space that a user might decide to keep. It can translate to very large
size (e.g. 1% = ~10GB on 1TB HDD) or very small (e.g. 1% = ~330MB on 32GB
system like Endless devices). Hence, it makes sense to introduce a config
option to honor specific size as per the user.

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.

When a new object is added to the repository, create a
$PAYLOAD-SHA256.payload-link symlink file as well. The target of the
symlink is the checksum of the object that was added the repository.
Whenever we add a new object file, in addition to lookup if the file is
already present with the same checksum we also check if an object with
the same payload is in the repository.
If a file with the same payload is already present in the repository, we
copy it with `glnx_regfile_copy_bytes` that internally attempts to
create a reflink (ioctl (..., FICLONE, ..)) to the target file if the
file system supports it. This enables to have objects that share the
payload but have a different inode and xattrs.
By default the payload-link-threshold value is G_MAXUINT64 that disables
the feature.

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

Today the rpm-ostree test suite uses `refs --create` to save
commits. I think this is a legitimate use case, and other
people may be doing something similar.
On the other hand, I think we should probably be changing the rpm-ostree test

we hit a real-world case where something needed to change.

This new option verifies that the refs listed in the ref-bindings for
each commit all point to that commit (i.e. there aren’t multiple commits
listing the same ref in their ref-bindings, and there aren’t any commits
with non-empty ref-bindings which aren’t pointed at by a ref).
This is useful when generating a new repository from scratch, but not
useful when adding new commits to an existing repository (since the old
commits will still, correctly, have ref-bindings from when the refs
pointed at them). That’s why it has to be enabled explicitly using
--verify-back-refs, rather than being on by default.

For many cases of commit, we can actually optimize things by simply "adopting"
the object rather than writing a new copy. For example, in rpm-ostree package
layering.
We can only make that optimization though if we take ownership of the file. This
commit hence adds an API where a caller tells us to do so. For now, that just
means we `unlink()` the files/dirs as we go, but we can now later add the
"adopt" optimization.

This is the new way of publishing repository metadata, rather than as
additional-metadata in the summary file. The use of an ostree-metadata
ref means that the metadata from multiple upstream collections is not
conflated when doing P2P mirroring of many repositories.
The new ref is only generated if the repository has a collection ID set.
The old summary file continues to be generated for backwards
compatibility (and because it continues to be the canonical ref →
checksum map for the repository).
The new code is only used if configured with --enable-experimental-api.

This option allows a repo to explicitly opt out of adding new remotes in
a remotes configuration directory. This currently defaults to true for
system repos and false for non-system repos to maintain legacy behavior
that non-system repos don't add remotes in a configuration directory.
That would be problematic for flatpak, which specifies a remotes config
dir but adds remotes in ways that are incompatible with it.
So, what this really does is allow system repos to control whether they
want to add remotes in the config dir or not. That's important if your
flatpak repo is the system repo like at Endless.
