Read the G_FILE_ATTRIBUTE_UNIX_IS_MOUNTPOINT attribute (unix::is-mountpoint) to
determine if a volume is a mount that udisks2 has detected. Ignoring these
prevents network mounts from showing up as devices.
GioLister::UnmountDevice calls g_object_unref on the GVolume object held by a
DeviceInfo. This appears to be left over from a time before DeviceInfo held
onto the volume.
Using libmtp or libgphoto2 to access a device that gvfs has mounted causes the
connection to fail. libmtp is calling libusb_claim_interface which, according to
libusb documentation, will return LIBUSB_ERROR_BUSY if claimed by a different
program. For mtp and gphoto2 devices discovered by the GioLister, use the file
scheme and access the device through the gvfs mount.
The uri returned from g_file_get_uri is percent encoded. This causes the regex
in GioLister::MakeDeviceUrls to fail and causes the URL to be invalid. In this
case, it falls back to the file scheme. Newer versions of gvfs obtain the serial
id from udev instead of using the bus and device IDs.
Note that this bug covers a different issue where mtp is failing to connect. The
result is actually desired behavior. The follow-up change will address this.
In 1.37.2, gvfs switched to URIs that remain consistent across USB device
re-enumerations. This removed the usb bus and device numbers from the URI. In
the case that these values aren't found in the URI, try to parse Unix device
name property and pass results as query params on the URL. Pay attention to
these params in MtpConnection.
See gvfs commits 3a7bb06b and efc76d0c for reference.
GError messages contain non-ascii characters. This normally just produces some garbage when we use the default QString contructor that assumes ASCII for logging. However, when a message includes the right double quote, UTF-8 sequence 0xE2 0x80 0x9D, the final byte is OSC. VT100 expects a command sequence to follow and stops echoing output until it sees ST or BEL character, which may never come. Thus, the console output is halted.
This change uses QString::fromLocal8Bit instead of depending on the default constructor. About half of the sites in the codebase had already been converted.
One side effect is that log messages are quoted. There are additional options to control this, but those were only introduced in Qt 5.4.
