Whenever a plugin has probed for some information in a given port, that data
should be available for any other plugin wanting it during its own probing
process. This new cache of Port Probe results allows to easily retrieve the
already probed information.
The new `MMPortProbeAtCommand' type defines what command will be sent to the
serial AT port, and also a response processor method to parse the string
returned by the port.
The response processor gets as input either the text reply string or an error,
and it should give as output either a GValue (type depends on the probing kind
being done) or a new error (which will force the whole probing process to be
aborted.
Also removed the MMSerialError implementation from `src/mm-errors.[h|c]', as it
is now included in the new `include/ModemManager-errors.h' header file. All the
other enums and errors without clashing names will be ported afterwards to the
new base code.
Which requires that we turn it into a GInterface that MMModemBase
can implement, because dbus-glib does not allow attaching more
than one introspection glue structure to an object at a time.
Also implement the standard D-Bus properties changed signal.
Ignore devices that aren't completely configured by udev yet. If
ModemManager is started in parallel with udev, explicitly requesting
devices may return devices for which not all udev rules have yet been
applied (a bug in udev/gudev). Since we often need those rules to match
the device to a specific ModemManager driver, we need to ensure that all
rules have been processed before handling a device.
Do this by adding an item to the environment of each device that MM
might possibly be interested in, and ignoring devices that don't
have that. When the device is fully processed by udev, MM will get
an 'add' event and the device will have all rules applied.
We currently convert to and from the modem's set charset and always pass
'15' as the data coding scheme. Passing the correct data coding scheme
as third argument to CUSD only upsets the network. This contradicts 3GPP
TS 23.038. Other tools like gsm-ussd handle it the same way.
Network responses that require further actions are not yet implemented.
(some fixes and cleanups by Dan Williams)
When the support is complete, use --with-polkit to enable
PolicyKit support. It's not there yet, but this commit adds an
authorization provider framework which will be extended to allow
hooking into PolicyKit.
For QCDM devices we want most of what MMSerialPort does, but not
the AT command handling stuff since the commands and responses
aren't AT commands nor are they even strings. So convert everything
that MMSerialPort does into a GByteArray, and let MMAtSerialPort
handle the conversion to strings when necessary.
Get rid of dependency on HAL, using libgudev instead. Fix up the plugin API
to no longer use either HAL or udev defines, but let plugins use whatever
mechanism they want for getting more information out of the device given the
subsystem and device node name.
Modems are now defined as "master" devices which "own" a one or more ports.
A port could be a serial tty device or a network device or whatever. The
plugin figures out whether it supports a given port or not and then assigns
it to a new or existing modem. Modems now have a 'valid' property that
should be set to TRUE when the modem has enough ports to operate correctly.
For devices (ex. 'hso') that use a network device for data transfer, the
modem would need to grab at least one TTY and the network device associated
with that physical device to be 'valid'.
Also move the generic modem support code to a plugin like other modem plugins,
and change the I-support-this-device mechanism to return a number indicating
the level of support. For example, the generic plugin would return a quite
low number if the device indicates via probing that it can do GSM or CDMA, but
a more specific plugin can indicate better support for the device, and thus
the more specific plugin would win control.
Implement registration using unsolicited messages for generic GSM class (which
is disabled by default, HSO and Huawei plugins enable it).
Modify all GSM modem subclasses that used unsolicited messages to use the new
method.
Instead of vague "send something, wait something" the responses are now
analyzed by (overridable) parsers. Makes all the modem implementations much
easier since each caller knows without any code whether the call succeeded
or failed.
Another thing that makes modem code simpler (and the whole thing more robust),
is the queueing of sent commands. Each queued command has a command and a
callback which is quaranteed to get called, even if sending failed.
Define and implement error reporting.
