Now devices can have multiple GUIDs and do not share platform IDs there is
really no point waiting to add the device.
This allows us to remove a whole lot of code for this now-unused functionality.
It wasn't hugely clear what the platform ID was actually meant to represent. In
some cases it was being used like a physical ID, in others it was a logical ID,
and in others it was both. In some cases it was even used as a sysfs path.
Clear up all the confusion by splitting the platform ID into two parts, an
optional *physical* ID to represent the electrical connection, and an optional
*logical* ID to disambiguate composite devices with the same physical ID.
Also create an explicit sysfs_path getter for FuUdevDevice to make this clear.
This allows WAIT_FOR_REPLUG to always work, rather than depending on the order
that the GUIDs were added, and that the kernel would always return the same
sysfs path (which it doesn't have to do, especially for hidraw devices).
The daemon creates a baseclass of either FuUsbDevice or FuUdevDevice when the
devices are added or coldplugged to match the quirk database and to find out
what plugin to run.
This is proxied to plugins, but they are given the GUsbDevice or GUdevDevice and
the FuDevice is just thrown away. Most plugins either use a FuUsbDevice or
superclassed version like FuNvmeDevice and so we re-create the FuDevice, re-probe
the hardware, re-query the quirk database and then return this to the daemon.
In some cases, plugins actually probe the hardware three times (!) by creating
a FuUsbDevice to get the quirks, so that the plugin knows what kind of
superclass to create, which then itself probes the hardware again.
Passing the temporary FuDevice to the plugins means that the simplest ones can
just fu_plugin_device_add() the passed in object, or create a superclass and
incorporate the actual GUsbDevice and all the GUIDs.
This breaks internal plugin API but speeds up startup substantially and deletes
a lot of code.
Similar to commit 7d35278 regarding the install option with a daemon compiled without
GPG, but now, if you also have a daemon compiled without GPG, and if you have downloaded a
CAB file from LVFS and ran get-details, it would fail to display the contents
of the associated CAB file.
This allows it to still display the contents of the CAB file, and
a warning will be displayed in the logs.
This allows us to match non-DeviceID GUIDs, and also GUIDs we don't know how to
generate.
To make this fully useful, search for device quirks when GUIDs are added.
Allowing plugins to 'register' for different udev subsystems in _init() allows
us to move the client to the engine, reducing the number of wakeups considerably
for each device event. It also will reduce the amount of boilerplate code in
each plugin that uses GUdev, much like we have done for GUsb.
Some devices take a long time to initialize and tools like fu-tool
have no feedback during this time.
Show a status message to indicate what's going on.
This isn't useful for most people and just takes up space in the logs.
When there is a problem it's typically specifically with a plugin
and at that time we ask them to run the daemon with verbose anyway.
In this instance, we define the 'same device' to be a FuDevice that has at
least one matching GUID. We allow the plugins to define which one is 'better'
than other plugins, and use this to only have one FuDevice for the physical
device.

Fix a logic error when testing requirements; what was supposed to happen was
that a the firmware requirements were only processed when we had a FuDevice set
in the FuInstallTask, but instead we were falling through to the handler for
'unknown requirement type'.
This pivots the data storage so that the group is used as the preconditon
and the key name is used as the parameter to change. This allows a more natural
data flow, where a new device needs one new group and a few few keys, rather
than multiple groups, each with one key.
This also allows us to remove the key globbing when matching the version format
which is often a source of confusion.
Whilst changing all the quirk files, change the key prefixes to be more familiar
to Windows users (e.g. Hwid -> Smbios, and FuUsbDevice -> DeviceInstanceId)
who have to use the same IDs in Windows Update.
This also allows us to pre-match the desired plugin, rather than calling the
probe() function on each plugin.
Not calling dozens of ->probe() functions is dramatically more efficient when
there are a large number of USB devices attached.
This requires plugins to 'opt-in' to the new behaviour, and also to supply
quirks that match all devices.
If the daemon either de-duplicates or replaces the object passed emitted from
device-added then the object set as the alternate may not be the same instance
as the daemon version. This causes weird things to happen.
To make this less fragile, specify the *ID* of the object that should be the
alternate device, which allows the daemon to do clever things, and then assign
the object from the ID as the last step.
Although fixing no bug, this makes implementing future functionality easier.
Now we can update multiple devices (in multiple plugins) using one firmware
archive we need a way to cleanup after all the plugins have been run.
Fixes https://github.com/hughsie/fwupd/issues/561
This can be used to select the AA.BB.CC.DD format rather than the default
AA.BB.CCDD format for firmware versions. This allows us to support new vendor
requirements without adding more complicated rules to the quirk file.
Fixes a segfault that occurs during cleanup of USB plugins.
When g_module_close was called memory allocated by the plugin would
get freed leading to the finalize method for object class pointing
to garbage.
When developing code it's really convenient to only run the new plugin. This
means you don't have to wait for the other hardware to initialize and there
are no side-effects from other plugins when installing firmware.
You can specify multiple plugins as globs, for instance:
fwupdtool get-devices \
--plugin-whitelist wacom \
--plugin-whitelist "thunderbolt*"
