Changed the versioning system to a 4 number system that have the first 2
numbers as major.minor for the host application itself and the next 2
numbers (tcp_rev.mod_rev) used by clients and modules to determine
compatibility. A full description of this new system has been edited
into protocol.md. This new system offically starts at v3.0.0.0.
Added the PROMPT data type id that will work exactly like PRIV_TEXT except
it tells the client that the command is asking for non-private information
from the user.
Added PROG and PROG_LAST type ids that can be used by commands to notify
the client of the progress of the command if it is long running. The
long running fs_* commands were updated to use these instead of TEXT for
progress updates.
PUB_IPC, PRIV_IPC and PUB_IPC_WITH_FEEDBACK have all been combined into
one: ASYNC_PAYLOAD. This type id is now the only means at which module
commands can now run async commands. The command process object will
now determine where to direct the async payload (public, private or
public with feedback) based on the async command id being requested.
A description for TERM_CMD was missing in data_types.md so it was added.
Refactored HALT_CMD to YIELD_CMD. The new name just seems more appropriate
or the effect it has on the command.
Module commands can now do input hooking using the new ASYNC_HOOK_INPUT
and ASYNC_UNHOOK async commands. input hooking basically makes it so all
client data gets redirected to the module command that initiated the hook.
This can be used to implement something like a EULA agreement that blocks
all actions that can place during the session until the user accepts or
anything else to that effect.
The command process object will now check the open sub-channels list
being sent by ASYNC_CAST or ASYNC_LIMITED_CAST in any order and will not
be required match exactly to open sub-channels list in the session object.
It however cannot contain sub-channels not already listed in session's
list or else the async payload will be blocked.
Fixed the CmdProcess::validAsync() function that was comparing the input
aysnc command id with the process's command id in some places which is
invalid logic for this function.
Fixed the 'cast' core command that was outputting a malformed async
payload that didn't include the open writable sub-channels list.
Fixed a bug that caused all casted payloads to be forwared to the clients
even when the sub-channel(s) are closed.
Fixed the 'set_disp_name' core command so it can now see the -new_name
argument properly.
fixed some errors found in the documentation and fully updated the internal
commands docs as well.
also updated the internal module to now respond to KILL_CMD so it can now be
signaled to terminate gracefully.
-the add_mod command now requires the -mod_path argument as it should.
-the session now filter out bad NEW_CMD frames based on bad command names and incorrect
frame sizes.
-modules running in list mode can now send ERR frames to the session to log error
messages to the host database.
