GLib creates two static inline functions for paramaters that may
not be used that set off warnings in clang but not gcc.
Ignore these on clang builds everywhere that
G_DEFINE_AUTOPTR_CLEANUP_FUNC is used.
In newer releases libusb has started returning LIBUSB_TRANSFER_ERROR (rather
than the arguably more correct LIBUSB_TRANSFER_STALL...) when the device is
removed before the control transfer has completed.
By filtering out the devices not in runtime we have two problems:
* We can't use fwupdmgr to 'fix' any devices that failed to flash and are
stuck in bootloader mode
* We can't transition from a runtime-less FuDevice to a DFU-capable FuDevice.
This allows the Nitrokey to be updated using fwupd.
Although we don't quite do the right thing, we only need to typically work out
the start offset of the firmware. This fixes 'dfu-tool dump foo.hex' for files
produced for the ATMEL ATXMEGA architechure.
Previously, the various install paths were obtained using get_option
as needed.
This patch unifies the directory selection inside the top-level meson
file as requested in https://github.com/hughsie/colord/pull/62.
This allows us to flash hardware like the Retrode and other devices using chips
like the AT90USB1287.
The test files can be re-generated using the sample code found here:
https://github.com/hughsie/fwupd-test-firmware and are designed
to be used on the AT90USBKEY2 development board.
It's actually less scary to see a SHA1 hash than it is to see a path like
/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2. It's also way easier to
copy and paste into the various fwupdmgr command that require a device ID and
also means we can match a partial prefix much like git allows.
If we also move to a model where plugins can be changed during different stages
of the update (e.g. during detach) then the device might change connection type
and then the sysfs path not only becomes difficult to paste, but incorrect.
Session software doesn't care about the format of the device ID (it is supposed
to be an implementation detail) and so there's no API or ABI break here. A few
plugins also needed to be ported, but nothing too worrying.
This allows end-users testing a specific plugin to start fwupd with an extra
command line parameter, e.g. `--plugin-verbose=unifying` to output a lot of
debugging information to the console for that specific plugin.
This replaces a lot of ad-hoc environment variables with different naming
conventions.
This also adds an *almost* throw-away python script to import the chip-ids from
the default conf file from the avrdude project. I've imported it here in case we
have to start caring about different page sizes or application offsets.
Notably, bootloaders for this class of device export an incorrect DFU interface.
Additionally, allow setting the buffer size for the UPLOAD to a larger size
than the defined device transfer size, which allows us to return the full
packet from the larger XMEGA devices.
