A Few Bug Fixes
- fixed a bug that prevented the creator of a channel from being added to it's member list as the owner. - fixed a bug that caused the host to open all sub-channels in read only mode. - fixed a bug that caused mod processes to not get called to shutdown when the session is closed. - removed the internal module idle timer, this removed an un-needed redundancy. with that, the idle timeout for mod processes are now 5 secs while the timeout for cmd processes remain at 2 mins. |

New versioning system, type ids and a few bug fixes
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. |

Major upgrade and module interface changes
Made some major changes to the project to facilitate a lighter code base and the must flexible module interface possible. -the mutli-process architecture now operate at the command object level so each command now operate in it's own process instead of a single process handling multiple command objects. -each module is now an independent application that will now tell the session object all of the commands it can run via named pipe. during command execution, it will run the requested command object also running io with the session object via named pipe. with this change, it is now possible for modules to be developed in different versions or QT or entirely different languages. the only requirement is the need to support named pipes. shared memory segments is also a nice to have but not needed. -clients can now run multiple instances of the same command via changes to the protocol. mrci frames will now include a branch id along with the command id. the branch id can be used by clients to differentiate the io between instances of the same command. -the command states are longer controlled by a single object. it will now be up to the command object (internal/exterenal) to send an IDLE frame to the client to notify it that the command has finished. the session object will still track if the command is in idle state or not but not directly control it. -must async commands now use binary formatted data instead of TEXT as a way to reduce overhead. -all command objects can now send async commands. it is no longer limited to just internal commands, however; the data of these async commands are verified by session in some way to prevent host crashing due to malformed data. -changed up the database structure to rely more on user ids, channel ids and removed all foreign keys pointing to user names, channel names and sub-channel names. also removed the groups table altogether. instead, the host rank is now directly attached to the user data in the users table. -changed the query object to now support the INNER JOIN SQL clause. this change was needed to support the new database structure. -version negotiation is now one-way via tcp connection or module interface. the host will make it's own verion numner known to the client connected via tcp or the module connected via named pipe. it will now be entirely up to the client or module to decide if they support the host. another change in this regard is the removal of the import rev for the modules. compatibility for modules shall now use just the host verion. -removed ls_cmds and cmd_info. the NEW_CMD frame now carries all information about the command (cmd_id, cmd_name, summery, io and full_description) so it is now possible for the clients to display the command documentation instead of the host. Documentation for the internal commands were updated to reflect the changes but all other documentation will need to be updated in the near future. |
