Prior to this commit, the ssh communicator would use the default cipher
list in Net::SSH to negociate which ciphers it should use between hosts.
Due to a bug in Net::SSH and the position of the `none` cipher in its
default cipher list, if a host supported the none cipher, but also
only supported other ciphers that came after none in the default list,
it would accept none and attempt to use that cipher instead of the other
supported ciphers. This commit fixes that behavior by copying the
default cipher list from Net::SSH and placing none last in the list so
that other ciphers can be used in the negotiation before attempting to
use the unsecure none cipher.
Prevent sending empty data strings to defined blocks handling
stderr and stdout output. These can occur when the garbage
marker is identified and collected data pruned, but no remaining
data is left to send.
Fixes#8259
We gained a ton of improvemnts to WinRM error handling in
https://github.com/mitchellh/vagrant/pull/4943, but we also got one bug.
The new code raises an exception when `winrm_info` does not return right
away. This was preventing us from catching the retry/timout logic that's
meant to wait until boot_timeout for the WinRM communicator to be ready.
This restores the proper behavior by rescuing the WinRMNotReady
exception and continuing to retry until the surrounding timeout fires.
Command failures include the stdout and stderr in the error message just like the SSH communicator.
Its now possible to specify only an error_class and have that use the correct error_key by default.
Elevated command line is now rendered to a script which is uploaded to the guest and executed. This allows the command line itself to be less than 100 chars to start the script and any user commands are puts into the script which has unlimited* length.
These will be used to replace the guest side command_alias script that is sent with every communicator execute call. This avoids some uncessary remote calls to the guest, makes it unit testable, and allows larger PowerShell commands to be invoked.
