Protocol: AttributeError: 'NoneType' object has no attribute 'ReadUntilClose'

[eismog]

Hi,

I will get an error, when I run two error command:

Like this:

import os.path as op

from adb import adb_commands
from adb import sign_m2crypto


# KitKat+ devices require authentication
signer = sign_m2crypto.M2CryptoSigner(
 op.expanduser('~/.android/adbkey'))
# Connect to the device
device = adb_commands.AdbCommands.ConnectDevice(
 rsa_keys=[signer])
# Now we can use Shell, Pull, Push, etc!
# for i in xrange(10):
# print device.Shell('echo %d' % i)

print device.Shell('ls 333')
print device.Shell('ls 222')
print device.Shell('ls 111')
device.Close()

result:

/usr/bin/python2.7 /home/ligf/PycharmProjects/test-adb/tmp.py
ls: 333: No such file or directory
Traceback (most recent call last):

 File "/home/ligf/PycharmProjects/test-adb/tmp.py", line 18, in <module>
 print device.Shell('ls 222')

AttributeError: 'NoneType' object has no attribute 'ReadUntilClose'

Process finished with exit code 1

It may be a bug at here:
adb_protocol.py

 if cmd == b'CLSE':
 # Device doesn't support this service.
 return None
 if cmd != b'OKAY':
 raise InvalidCommandError('Expected a ready response, got %s' % cmd,
 cmd, (remote_id, their_local_id))
 return _AdbConnection(usb, local_id, remote_id, timeout_ms)

The same problem. Has it been solved?

My phone is Huawei Honor 8.

Can you add this between line 253 and 254 of adb/adb_protocol.py: print command

Then run it again and paste the output here, please. This should only be happening if the device is either sending two CLSE responses or the library isn't handling the first CLSE in time.

Hi
the print output is here. The number 0 is the output of the first loop, the item in buckets are the output of print(command, arg0, arg1, bytes(data))

This also seems to be a problem on an LG G6

Here's the output of print:
CNXN
OKAY
WRTE
CLSE

CLSE

This fixes the issue (in the Open method), I'm not sure if it's the best fix though:

 if cmd == b'CLSE':
 # Some devices send two CLSEs
 cmd, remote_id, their_local_id, _ = cls.Read(usb, [b'CLSE', b'OKAY'],
 timeout_ms=timeout_ms)
 # Device doesn't support this service.
 if cmd == b'CLSE':
 return None

I am still affected by this issue

File "/usr/lib/python2.7/site-packages/adb/adb_commands.py", line 366, in Shell
timeout_ms=timeout_ms)
File "/usr/lib/python2.7/site-packages/adb/adb_protocol.py", line 406, in Command
return ''.join(cls.StreamingCommand(usb, service, command, timeout_ms))
File "/usr/lib/python2.7/site-packages/adb/adb_protocol.py", line 434, in StreamingCommand
for data in connection.ReadUntilClose():
AttributeError: 'NoneType' object has no attribute 'ReadUntilClose'

And my adb_protocol.py already contained

 if cmd == b'CLSE':
 # Some devices send two CLSEs
 cmd, remote_id, their_local_id, _ = cls.Read(usb, [b'CLSE', b'OKAY'],
 timeout_ms=timeout_ms)
 # Device doesn't support this service.
 if cmd == b'CLSE':
 return None

Any help would be greatly appreciated as it seems to fail randomly and during periods of high ADB traffic.

Bump. This is plaguing my app like nothing else.

[alxhoff]

After having a fresh google around PR #151 seems to of fixed it up.

@alxhoff Thanks for the confirmation. If Google loves open source so much it'd be great if they gave developers of their open-source projects the time necessary to review and merge bug fixes to them 😀 😀 😀
For myself I'll probably be forced to distribute my own fork of this package.
