Disconnect gracefully from ogServer after booting OS, the script to start the
OS calls kexec, so everything is gone after it. For Windows, this results in a
reboot.
This commit also improves the disconnect function to make sure the
disconnection is synchronous.
ogAdmClient has a support for initializing the session in the machine. This new
command allows the new ogClient to execute the same script to init the session.
The arguments will be received from the server as a json message. Format:
{ "disk" : "0", "partition" : "1"}
Opengnsys needs a support to execute commands on the machine. This patch adds
the support for executing two new commands "shell/run" and "shell/output". The
first one, give us the support for executing a command in the machine and keep
save in a queue the output. The second one, give us the support for sending the
output from the command executed.
To disconnect the socket or send a message we use in different parts of the code
the attribute socket which is declared inside of the client. This way will
create us important problem in the future if we want to change the behavior in
our client sockets. This patch adds two new methods inside the client and we
can use them in other classes giving us the easy way to send messages and
disconnect the client.
Our program sends always the HTTP message:
HTTP/1.0 200 OK
but if the operation sent is not supported, we are sending the same correct
message. This patch add the support to check if the message is supported.
If the message is not supported, we are going to send:
HTTP/1.0 400 Bad request\r\n\r\n
Otherwise, in operations supported:
HTTP/1.0 200 OK
The new OpenGnsys support to communicate server and client side will be
HTTP. This new class allows us the support for parsing all the message received
from the server in HTTP format.
During our connections, we are using states to control the Client Socket. We
defined using global variables. In case that we modify this global variable,
we need to change it in serveral parts of the code.
Using enums and declaring a new class, we can redefine the values or create new
states without changing the same code in differents python files.
