We have some extra conditions here that are not evident
from the rename-icon key in the manifest, so add some
verbose output to make it easier to figure out why an
icon is not renamed.
This allows you to add multiple paths at the same time, plus
grant an app access to it, plus it returns the fuse mount path.
This allows you to avoid a lot of roundtrip in common cases.
We artificially limit the metadata phase to the first 20 metadata
objects, because otherwise that phase takes too long time, as it
downloads content at the same time.
For the delta case we can get perfect results by just ignoring
the counts and relying on the sizes. However, this needs a
recent ostree that supports the fetched-delta-part-size field.
For the object case we keep using the object average size
to estimate a size which we can compare with the extra data
size.
Now that we have access to the total extra-data download size,
we can have much more precise progress reports by summing up
all the download sizes from OSTree and extra-data.
This patch makes the progress report callback use the extra-data
sizes, as well as calculate the average size (in bytes) of the
content.

There is a race condition in how the portals detects the peer app-id.
If we manager to open /proc/$pid/root, and then openat(fd,
".flatpak-info"), but the process dies inbetween the two, then the
.flatpak-info read-only bind mount (and all other mounts in the
namespace except the root one) is unmounted, so we will find
and empty .flatpakinfo file.
We fix this race by storing the contents in a regular file, but
also as a readonly bind mount on top of it.
For typical dbus portals the pid is the dbus proxy though, and in
that case the app can't modify the file, so we make it just
a file there instead of file + bind-mount.
This allows us to rely on the new BARE_USER_ONLY mode, as
well as the fixes to progress reporting. Also, it has a lot
of bugfixes that are nice. If you need an old ostree you can
run the old flatpak series.
Flatpak relies on OSTree to report the progress, and
OSTree's progress report frequency fallbacks to 1 second.
Recently, however, OSTree received support for setting
custom update frequencies. Since it relies on GVariant
options, if the user has an older OSTree, it'll simply
be ignored.
This patch, then, makes Flatpak report progress every
100ms rather than the default value of 1 second.

We only allow globs, not magic matches, and we drop the glob
priority to a very low level (weight=5) which means that its
hard for app-installed mimetypes to override the system installed
ones. That should make exporting mimetypes pretty safe.
Installing a search provider is a minor security issue, as it
can see all that you search for in the desktop, so we rewrite
these so that they are always disabled by default. The user
can then chose to enable it if he wants.
Instead of exporting any files we add a whilelist
of directories that get exported:
share/applications
share/icons
share/dbus-1/services
share/gnome-shell/search-providers
share/mime/packages
This avoids potentially installing some kind of file that the
host system reads and interprets in a risky way.
Applications and dbus services are safe because we rewrite them.
Icons are safe as long as the image loaders are, and if they are
not we have worse problems.
Search providers and mime formats are somewhat problematic, and
follow-up commits will rewrite these to be safer.
We may have made decisions based on the permissions listed in the
metadata in the (signed, thus trusted) commit. However, at runtime
we actually look at the metadata file that is deployed. Make sure
these are the same by comparing them when we deploy.
When we're pulling via the system-child repo we don't inherit
the commitpartial state from the parent, so we didn't know a
commit was partial, so the full contents was not downloaded.
This fixes updating a partial install to the same commit, but
with different subsets.
We don't guarantee that the active link is identical to the
checksum anymore. If you really need the checksum you have
to look at the deploy data.
This is mainly changing the names from "checksum" to "active_id"
in the code that touches the active link, except the case where
we're undeploying after an update. We then use the old active
link value rather than the old commit id as the undeploy id.
This will allow us to have partial deploys with different names
than the full or differently partial deploy.
