If a copy of the MPL was not distributed with this file, +# You can obtain one at http://mozilla.org/MPL/2.0/. + +"""mozdevice provides a Python interface to the Android Debug Bridge (adb) for Android Devices. + +mozdevice exports the following classes: + +ADBProcess is a class which is used by ADBCommand to execute commands +via subprocess.Popen. + +ADBCommand is an internal only class which provides the basics of +the interfaces for connecting to a device, and executing commands +either on the host or device using ADBProcess. + +ADBHost is a Python class used to execute commands which are not +necessarily associated with a specific device. It is intended to be +used directly. + +ADBDevice is a Python class used to execute commands which will +interact with a specific connected Android device. + +ADBAndroid inherits directly from ADBDevice and is essentially a +synonym for ADBDevice. It is included for backwards compatibility only +and should not be used in new code. + +ADBDeviceFactory is a Python function used to create instances of +ADBDevice. ADBDeviceFactory is preferred over using ADBDevice to +create new instances of ADBDevice since it will only create one +instance of ADBDevice for each connected device. + +mozdevice exports the following exceptions: + +:: + + Exception - + |- ADBTimeoutError + |- ADBDeviceFactoryError + |- ADBError + |- ADBProcessError + |- ADBListDevicesError + +ADBTimeoutError is a special exception that is not part of the +ADBError class hierarchy. It is raised when a command has failed to +complete within the specified timeout period. Since this typically is +due to a failure in the usb connection to the device and is not +recoverable, it is implemented separately from ADBError so that it +will not be caught by normal except clause handling of expected error +conditions and is considered to be treated as a *fatal* error. + +ADBDeviceFactoryError is also a special exception that is not part +of the ADBError class hierarchy. It is raised by ADBDeviceFactory +when the state of the internal ADBDevices object is in an +inconsistent state and is considered to be a *fatal* error. + +ADBListDevicesError is an instance of ADBError which is +raised only by the ADBHost.devices() method to signify that +``adb devices`` reports that the device state has no permissions and can +not be contacted via adb. + +ADBProcessError is an instance of ADBError which is raised when a +process executed via ADBProcess has exited with a non-zero exit +code. It is raised by the ADBCommand.command method and the methods +that call it. + +ADBError is a generic exception class to signify that some error +condition has occured which may be handled depending on the semantics +of the executing code. + +Example: + +:: + + from mozdevice import ADBHost, ADBDeviceFactory, ADBError + + adbhost = ADBHost() + try: + adbhost.kill_server() + adbhost.start_server() + except ADBError as e: + print('Unable to restart the adb server: {}'.format(str(e))) + + device = ADBDeviceFactory() + try: + sdcard_contents = device.ls('/sdcard/') # List the contents of the sdcard on the device. + print('sdcard contains {}'.format(' '.join(sdcard_contents)) + except ADBError as e: + print('Unable to list the sdcard: {}'.format(str(e))) + +Android devices use a security model based upon user permissions much +like that used in Linux upon which it is based. The adb shell executes +commands on the device as the shell user whose access to the files and +directories on the device are limited by the directory and file +permissions set in the device's file system. + +Android apps run under their own user accounts and are restricted by +the app's requested permissions in terms of what commands and files +and directories they may access. + +Like Linux, Android supports a root user who has unrestricted access +to the command and content stored on the device. + +Most commercially released Android devices do not allow adb to run +commands as the root user. Typically, only Android emulators running +certain system images, devices which have AOSP debug or engineering +Android builds or devices which have been *rooted* can run commands as +the root user. + +ADBDevice supports using both unrooted and rooted devices by laddering +its capabilities depending on the specific circumstances where it is +used. + +ADBDevice uses a special location on the device, called the +*test_root*, where it places content to be tested. This can include +binary executables and libraries, configuration files and log +files. Since the special location /data/local/tmp is usually +accessible by the shell user, the test_root is located at +/data/local/tmp/test_root by default. /data/local/tmp is used instead +of the sdcard due to recent Scoped Storage restrictions on access to +the sdcard in Android 10 and later. + +If the device supports running adbd as root, or if the device has been +rooted and supports the use of the su command to run commands as root, +ADBDevice will default to running all shell commands under the root +user and the test_root will remain set to /data/local/tmp/test_root +unless changed. + +If the device does not support running shell commands under the root +user, and a *debuggable* app is set in ADBDevice property +run_as_package, then ADBDevice will set the test_root to +/data/data/<app-package-name>/test_root and will run shell commands as +the app user when accessing content located in the app's data +directory. Content can be pushed to the app's data directory or pulled +from the app's data directory by using the command run-as to access +the app's data. + +If a device does not support running commands as root and a +*debuggable* app is not being used, command line programs can still be +executed by pushing them to the /data/local/tmp directory which is +accessible to the shell user. + +If for some reason, the device is not rooted and /data/local/tmp is +not acccessible to the shell user, then ADBDevice will fail to +initialize and will not be useable for that device. + +NOTE: ADBFactory will clear the contents of the test_root when it +first creates an instance of ADBDevice. + +When the run_as_package property is set in an ADBDevice instance, it +will clear the contents of the current test_root before changing the +test_root to point to the new location +/data/data/<app-package-name>/test_root which will then be cleared of +any existing content. + +""" + +from .adb import ( + ADBCommand, + ADBDevice, + ADBDeviceFactory, + ADBError, + ADBHost, + ADBProcess, + ADBProcessError, + ADBTimeoutError, +) +from .adb_android import ADBAndroid +from .remote_process_monitor import RemoteProcessMonitor + +__all__ = [ + "ADBError", + "ADBProcessError", + "ADBTimeoutError", + "ADBProcess", + "ADBCommand", + "ADBHost", + "ADBDevice", + "ADBAndroid", + "ADBDeviceFactory", + "RemoteProcessMonitor", +] diff --git a/testing/mozbase/mozdevice/mozdevice/adb.py b/testing/mozbase/mozdevice/mozdevice/adb.py new file mode 100644 index 0000000000..bf3029c2f4 --- /dev/null +++ b/testing/mozbase/mozdevice/mozdevice/adb.py @@ -0,0 +1,4438 @@ +# This Source Code Form is subject to the terms of the Mozilla Public +# License, v. 2.0.
