• Operating System: Windows 10 64bit
• Python version: Python 3.6.0 |Anaconda 4.3.0 (64-bit)
• VirtualBox version: 5.1.22
• VirtualBox SDK version: 5.1.22

• [v] Happens in latest master branch?

SUMMARY

file_copy_to_guest does not work file_copy_from_guest does. Code goes failed without ERROR.

STEPS TO REPRODUCE

   vm = vbox.find_machine("a-ubuntu-distro")
   session = vm.create_session()
   guest = session.console.guest.create_session("root","some-password")
   progress = guest.file_copy_to_guest("D:\\test2", "/tmp/test2", [virtualbox.library.FileCopyFlag.none])
   progress.wait_for_completion()

EXPECTED RESULTS

ls /tmp in VM and see the file.

ACTUAL RESULTS

progress.wait_for_completion() returns, but there are no file in /tmp

Did you check the error status of the progress object? See progress.result_code and progress.error_info.

[wahtherewahhere]

There are two kind of error messages. If the code is guest.file_copy_to_guest("D:\\test.txt", "/root/test2", [virtualbox.library.FileCopyFlag.none]) The error message is "The specified file was not found on guest" (result_code: -2135228411)

Another one is guest.file_copy_to_guest("/root/test2", "D:\\test.txt", [virtualbox.library.FileCopyFlag.none]). (I guess maybe the vbox api put the wrong parameters location so I change the sort.) The error message is empty (result_code: 0).

[sethmlarson]

Can you try using: guest.file_copy_to_guest('D:\\test.txt', '/root/test2', [virtualbox.library.FileCopyFlag.update]). Seems the update flag also allows a file to be created if it doesn't exist on the guest.

Source:

"""
    .. describe:: update(4)
            Only copy when the source file is newer than the destination file
            or when the destination file is missing.
            This flag is not implemented yet. 
"""

If this flag actually isn't implemented then you should try creating an empty file on the guest first before using copy? I'm just inferring that from the error message. The first parameter order is definitely the right one.

[sethmlarson]

This would be nice as a helper function, I should look into fixing these up in library_ext in 2.0.0.

[wahtherewahhere]

I organize the results in the following table. The flag update is not the solution. Only the first configuration works. A helper function is a good idea for wrapping this staffs :clinking_glasses: (cheers)

Create ?	Overwrite if exists?	Source	Target	Flag	Result Code	Error Message
:+1:	:+1:	D:\test.txt	/root/	[FileCopyFlag.none]	0	(n/a)
:x:	:x:	D:\test.txt	/root/test.txt	[FileCopyFlag.none]	-2135228411	The specified file was not found on guest
:x:	:x:	D:\test.txt	/root/	[FileCopyFlag.update]	-2135228411	Copy flags (0x4) not implemented yet
:x:	:x:	D:\test.txt	/root/test.txt	[FileCopyFlag.update]	-2135228411	Copy flags (0x4) not implemented yet

[sethmlarson]

Thanks for all these results! We definitely need to add a nice helper for this function because it doesn't behave like a typical copy.

[sethmlarson]

I'm glad we got to the bottom of this. I'm going to close this as complete, if you would like to add the helper to the project please do so against 2.0.0 branch. Thanks!

hi, im trying copy file from my machine to VM via using this code:

progress = guest_sesson.file_copy_to_guest("/home/user/Desktop/1.txt", "C:\\", [virtualbox.library.FileCopyFlag.none])
progress.wait_for_completion()

but progress.result_code is -2135228411 Are you have any ideas?

Yes, I have the same issue:

>>> progress = gs.file_copy_to_guest("/mnt/VM/python-3.7.6-amd64.exe","C:\test",[virtualbox.library.FileCopyFlag.none])
>>> progress.wait_for_completion()
>>> progress.error_info.text
'Destination file lookup for "C:\test" failed: VERR_GENERAL_FAILURE'

[malpwn]

Same issue as above can we please get this handled ?

[sethmlarson]

I don't have a lot of time to devote to this project. If you can do more investigation or provide a PR I'm willing to review.
