Some firmware has a different on-device checksum to the hash of the firmware
file itself. This may be because:
* The content is not a binary file, e.g. Intel HEX or SREC
* Only part of the firmware is flashed, e.g. ignoring the bootloader section
* The device checksum is calculated using another method entirely, e.g. PCR0
It's also made complicated as there may be more than one 'correct' device
checksum in some cases, but nothing that a union query can't solve.
We can't actually access the UEFI ROM from userspace, but the PCR0 is a hash
built from the ROM itself. We could use this value to ensure the firmware has
been written correctly, and that the PCR0 matches the expected value specified
in the metadata.
The client uses GObject introspection to use the libfwupd2 library.
The client offers a reduced set of commands, but may be useful in some
environments.
This speeds up matching for GUIDs by about 90%, taking the query from 3.17ms to
about 0.33ms on my Thinkpad. This is more important for slow ARM hardware,
where strcmp() is more expensive than on x64.
This matches what a lot of other projects do, and means we can easily format
the release notes back into NEWS format, but also into HTML and Markdown.
This also means we can show the correct update description in gnome-software
when building a flatpak, rather than falling back to the generic project
description.
The current libxmlb dependency requires this and when run in subproject
mode will cause failures otherwise.
Also bump the snap to use meson 0.47.2 to fix snap build due to this
failure.
1) Remove the confusing --firmware-id and build this field dynamically based on GUID and Developer name
2) Make developer name mandatory
3) Rename device-unique-id to device-guid to more closely reflect how fwupdmgr shows it
4) Allow running on Windows
The libxmlb library is much faster to query, and does not require the daemon
to parse the XML metadata at startup. It's a zero-copy mmap design that is more
modern and less clunky.
RSS has reduced from 3Mb (peak 3.61Mb) to 1Mb (peak 1.07Mb) and the startup
time has gone from 280ms to 250ms.
Leading to this problem:
Building fwupd-wrappers
Failed to copy '/build/fwupd/parts/fwupd-wrappers/build/snapcraft-stable.yaml': it's a symlink pointing outside the snap.
Fix it to be valid when snapped and try again.

Workaround for https://bugs.launchpad.net/launchpad/+bug/1797366
It was previously a symlink to contrib/snap/snapcraft-stable.yaml
however infrastructure changes in launchpad have caused this to break
automatic snap builds.
This plugin requires infrastructure introduced in fwupd 1.1.3
and can not be backported to earlier versions of fwupd.
It works together with the Synaptics and Thunderbolt plugins to
coordinate the proper flashing procedure for devices in this dock.
At least for me it was a challenge to get the debugger properly
configured to allow debugging fwupd when built in tree.
This should allow very simple debugging.
This is meant to produce standalone installer binaries that can operate
on machines without current tools or internet access.
It works by wrapping around the container technologies snap and flatpak
and putting all the pieces together.
