The CustomFlags feature is a bit of a hack where we just join the flags
and store in the device metadata section as a string. This makes it
inefficient to check if just one flag exists as we have to split the
string to a temporary array each time.
Rather than adding to the hack by splitting, appending (if not exists)
then joining again, store the flags in the plugin privdata directly.
This allows us to support negating custom properties (e.g. ~hint) and
also allows quirks to append custom values without duplicating them on
each GUID match, e.g.
[USB\VID_17EF&PID_307F]
Plugin = customflag1
[USB\VID_17EF&PID_307F&HUB_0002]
Flags = customflag2
...would result in customflag1,customflag2 which is the same as you'd
get from an enumerated device flag doing the same thing.
Add a FuDevice->ready() vfunc that is run after ->setup()
This allows plugins to perform setup actions that require quirk matches
after the instance IDs have been converted. This allows us to also
remove FuVliDevice->setup() as the ordering chain has been broken.
There are two USB-3 hubs internally (with the same VID&PID), and the
MSP430 is only attached to the top-level one.

Until gi-docgen is declared stable support either of them.
This effectively means that hand builds and CI builds will use
gi-docgen, but distro builds use gtk-doc-tools.
Shadow FwupdDevice::parent with FuDevice::parent so that we *also* set
the context and composite ID.
This means we can always install all components of the Lenovo docks.
This allows plugins to set the battery power state of the *machine* which means
we can automatically inhibit devices with FWUPD_DEVICE_FLAG_REQUIRE_AC set.
It also allows to set the BatteryThreshold to 25% for Lenovo hardware, and we
can override other vendors with further quirks as required.

The activation flag is stored into the history database, but not all
plugins will want to inherit it on coldplug the next time the daemon
is started.
For example the Dell Dock plugin will query this information from the
device and it will prevent getting into a bad state as a result.
Fixes: #3106
If only one plugin is enabled and there exists a device match for a GType that
has not been registered then the user sees a GType error about not being able
to create a device that wouldn't be created anyway.
By removing the error in the quirk parser we will catch actual errors in
fu_plugin_runner_backend_device_added() which actually does chcek for
FWUPD_PLUGIN_FLAG_DISABLED.

There is a lot of code in fwupd that just assigns a shared object type to
a FuPlugin, and then for each device on that plugin assigns that same shared
object to each FuDevice.
Rather than proxy several kinds of information stores over two different levels
of abstraction create a 'context' which contains the shared *system* state
between the daemon, the plugins and the daemon.
This will allow us to hold other per-machine state in the future, for instance
the system battery level or AC state.
We already have two things managing the UPDATABLE_HIDDEN->UPDATABLE transition,
and we're about to add a third.
Add a 'stackable' inhibit-style API so we do not accidentally mark a device as
updatable when it should remain hidden.
This allows us to 'nest' firmware formats, and removes a ton of duplication.
The aim here is to deprecate FuFirmwareImage -- it's almost always acting
as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow
custom types. If I'm struggling to work out what should be a FuFirmware and
what should be a FuFirmwareImage then a plugin author has no hope.
For simple payloads we were adding bytes into an image and then the image into
a firmware. This gets really messy when most plugins are treating the FuFirmware
*as* the binary firmware file.
The GBytes saved in the FuFirmware would be considered the payload with the
aim of not using FuFirmwareImage in the single-image case.
Keeping *internal* API and ABI compatibility makes working with an already
complex codebase more mentally demanding than it needs to be.
Remember: plugins should be in-tree and upstream! If your out of tree plugin
stops working then it should be upstream.
The public-facing libfwupd will remain API and ABI stable for obvious reasons.
We want to make it as easy as possible for devices to refuse to update on low
battery, as this will likely be one of the WWCB requirements.
Ideally devices will check the battery level inside the firmware, but by also
providing the battery level to fwupd we can give the user a warning *before*
the update has started and without switching the device into bootloader mode.
Devices may want to support more than one protocol, and for some devices
(e.g. Unifying peripherals stuck in bootloader mode) you might not even be able
to query for the correct protocol anyway.
It is far too easy to forget to set FWUPD_DEVICE_FLAG_NO_GUID_MATCHING for new
plugins, and without it it all works really well *until* a user has two devices
of the same type installed at the same time and then one 'disappears' for hard
to explain reasons. Typically we only need it for replug anyway!
Explicitly opt-in to this rarely-required behaviour, with the default to just
use the physical and logical IDs. Also document the update behavior for each
plugin to explain why the flag is being used.
This allows you to have two identical Unifying plugged in without one of them
being hidden from the user, at the same time allowing a HIDRAW<->USB transition
when going to and from bootloader and runtime modes.
This removes the workaround added in 99eb3f06b6.

This is typically a Linux sysfs path or USB platform ID and is used in a
different way to the physical ID. The physical ID is only set for some devices
after setup() and depends on the subsystem list, and this would not be defined
for devices that do not match a plugin.
This also fixes an regression where the FuDeviceList fails to match the new
FuUdevDevice device in fu_device_list_get_by_guids_removed() and instead
silently gets 'fixed up' only if FWUPD_DEVICE_FLAG_NO_GUID_MATCHING is not set.
This also allows us to move the various backends device caches to FuBackend as
we now have a suitable ID that is for just the backend to use.
If we're creating the child device using `Children=FuFooDevice|FOO&I2C_01` in
the quirk file then there's not actually anywhere to call FuDevice->setup()
on the child.
The logical place to do it is when we setup the parent, which is a NOP if
already called for the child. We also don't need to convert the child instance
IDs as it's already being handled during the child setup.
Tested-By: Ricky Wu <ricky_wu@realtek.com>
We only convert the instance IDs to GUID after setup() has been called, which
means if we add even more instance IDs to the device in functions like
fu_plugin_device_registered() they never actually get converted to the GUID
form too.
The end year is legally and functionally redundant, and more importantly causes
cherry-pick conflicts when trying to maintain old branches. Use git for history.
That giant uint64_t isn't looking so big now, and we'll want to add even more
to it in the future. Split out some private flags that are never useful to the
client, although the #defines will have to remain until we break API again.
Asking the user for the UID mapping isn't working very well, as it requires lots
of manual handholding. It also doesn't work very well when the device vendor
does not actually have a PCI ID or if the vendor has split into two entities.
Just use the OUI address as an additional VendorID and match any of the device
IDs against any of the metadata-supplied values.
The fprint daemon only keeps the device open for 5 seconds and then releases it,
which seems like a small window to hit.
But! We're asking the user to authenticate with the same device we're about to
upgrade so a different part of the stack woke up the hardware just before we're
about to deploy an update onto it.
Just retry a few times to make sure the device is idle. Use a flag to prevent
accidentally causing regressions in other plugins.
