 ====== X2Go Roadmap ======
-===== Still pending TODOs from April 2011 =====
-  * **Communication:**
+===== Pending X2Go Tasks/Features =====
-    * FIXME Wiki accounts for: John Sullivan, Alexander Crössmann (HEINZ?)
-    * send Wiki Changes to x2go-commits(?) -> Heinz (todo)
-===== Work in Progress =====
-<task>
+We have a pool of ideas that will be started working on some time in the future. Anyone who wants to start working on those ideas is welcome to contact us via IRC or the x2go-dev mailing list.
-TITLE: Improve Documentation
-PRIORITY: High
-ESTIMATE: 3 months
-PROGRESS: 5%
-ASSIGNED: Heinz, Morty, Mike, John, Alexander, ...
-DESCRIPTION: Use this Wiki to provide a good documentation for X2go
-</task>
-        * write man pages for scripts in $PREFIX/bin and $PREFIX/sbin (Mike -> DONE)
+View our brainstorm pool for X2Go [[wiki:development:new-feature-brainstorming|here]].
-        * improve Python API documentation (Mike -> DONE)
-        * rework and update Wiki pages (everyone -> TODO)
-<task>
+===== Active X2Go Tasks/Features =====
-TITLE: X2go Communications API definition
-PRIORITY: Normal
-ESTIMATE: 3 month
-PROGRESS: 40%
-ASSIGNED: Reinhard, Mike, Alex
-DESCRIPTION: Restructure the build method for NX libraries and x2goagent
-</task>
-Restructure build concept of NX libraries + x2goagent...
+==== Sponsored Improvement Requests ====
-<task>
+We have received funding from an anonymous donor that wishes to see the following issues fixed/features added:
-TITLE: X2go Communications API definition
-PRIORITY: Normal
-ESTIMATE: 3 month
-PROGRESS: 35%
-ASSIGNED: Mike, Basma, Felix, Dick
-DESCRIPTION: Provide X2go with a standard way of communication between the client and the server
-</task>
-Currently the communication between server and client is done by issuing commands to a shell of the server on the client that is accessed using ssh. To do that, a lot of data is transferred from server to client and back. This generates extra traffic and makes the client more complex than necessary. In fact most commands should be issued on the server instead of in the client. To allow for this a proper protocol should be defined and implemented. This project does exactly that. The protocol will be implemented using json, to allow for easy incorporation in the current clients. The server part is implemented in python and can be implemented in a coming version of x2go. A complete working implementation will be made using pyhoca-cli.
-      * Define API -> DONE (is committed in GIT)
+=== Prio #1 (not started yet) ===
-      * Reach consensus on the api -> DONE (Well, we didn't get feedback from EVERYONE)
+**Fix Lockup of OS X client when running multiple sessions //sequentially//**
-      * Produce unittests (use cases) -> ALMOST DONE
-      * Implement server-side -> ALMOST DONE (We still need to incorporate some errorchecking and some authorisation) The first version has been committed to GIT
-      * Implement client-side -> We started with some investigation
-      * Test
+At present, X2GoClient on OS X goes into an endless loop and has to be force-terminated after the second or third connection attempt.
-====== Somewhen (post-Baikal) ======
+Task assigned to: Mihai
-  * Review [[wiki:security:start#x2goprint|x2goprinting]]
-  * Review pulseaudio (If and how to add a pulse-server running on the server and not only the client)
-  * Merge x2go...bindings package into one Git project x2godesktopbindings that will heavily use xdg commands etc.
+**Run multiple instances of X2GoClient**, or multiple sessions from one instance, all simultaneously (kind of how pyhoca-gui works)
+must work on
+  * Windows
+  * OS X
+  * Linux (probably already does)
-===== NEAR FUTURE =====
+Stefan would love to see X2GoClient gain the multi-session feature from PyHoCa.  In fact, the GUI design of the taskbar icon's context menu hasn't made sense from the start, if X2GoClient is and will always be
+limited to one session.
-==== January 2012 ====
+Please look at the following screenshots/mockups for a display of the current situation and two alternatives:
+^ X2GoClient current look ^ X2GoClient single-session ^ X2GoClient multi-session ^
+| {{:wiki:development:x2goclient-current-look-notgood.png?200|}} | {{:wiki:development:x2goclient-if-limited-to-one-session.png?200|}} | {{:wiki:development:x2goclient-multiple-sessions.png?200|}} |
-  * Move over to AGPL licensing for nearly all X2go Git projects. Here is a list:
+If that is impossible, we need to make sure that multiple instances of x2goclient can co-exist in RAM.
-    * cups-x2go.git (TODO)
+Which will be a challenge for OS X.
-    * ltsp-pyhocathinclient.git (TODO)
-    * pinentry-x2go.git (Is it possible? Does the original code license allow that?)
-    * pyhoca-cli.git (TODO: Mike)
-    * pyhoca-gui.git (TODO: Mike)
-    * python-x2go.git (DONE for python-x2go >= 0.1.2.0)
-    * x2goadmincenter.git (TODO)
-    * x2goagent.git (possible?)
-    * x2goclient.git (TODO)
-    * x2godesktopsharing.git (TODO)
-    * x2gognomebindings.git (TODO)
-    * x2golxdebindings.git (DONE)
-    * x2goplasmabindings.git (TODO)
-    * x2goserver.git (TODO)
-    * x2gothinclient.git (TODO)
-    * x2gotrinitybindings.git (DONE)
-  * Make some progress on the bugtracker discussion...
+h1 has a design in mind that addresses multi-sesson support in one X2Go Client instance (also x2goclient2.git on git.x2go.org is capable of that, but at the moment it is half-baked and probably temporarily discontinued).
-===== DONE =====
+Steps:
+  - Fix Multi-Instance on Windows
+  - Write wrapper to turn Multi-Instance into Multi-Session mode (especially important for OS X, where Multi-Instance isn't supported)
-==== August 2011 ====
+Task assigned to: Mihai, Mihai, and again, Mihai - with some help by Mike#2 for the Windows client
+=== Prio #2 (not started yet) ===
+**Rebase the "Pulseaudio on Mac" code**
+//Side note: You need to coordinate your efforts with Mike#2 regarding the microphone mute function.//
+Task assigned to: Mihai
+**Improve x2go-broker functionality (shadowing, stable release)**
+Task assigned to: Mike#1 (8h)
+**Improve x2go-broker documentation**
+Task assigned to: Mike#1, Stefan (12-16h)
+**General improvement on documentation**
+Task assigned to: Stefan, aided by Mike#1 (hard to say, Mike#1 will coach Stefan for an equivalent of 4h to get things straight, no matter how long it takes)
+<del>**HTML5 Client**</del> tagged as unrealistic given current budget
+If budget remains, a HTML5 client would be nice.
+//There seems to be a disagreement amongst the developers regarding how such a client should be implemented.//
+  - One option would be to copy what other remote solutions are using - which means sub-par performance compared to our native NX/X2Go speeds.
+  - A from-scratch approach would bring native speeds, but is a time and money sinkhole.
+Task assigned to: <none yet> - could be Alex, Mihai, ...?
+<del>**Alternative to NX-Rewrite**</del> tagged as unrealistic given current budget
+h1 has some ideas what other F/LOSS codebases might be suitable as a time- and money-saving alternative to doing the NX-Rewrite.
+He should mention them on x2go-dev to get more feedback, then a competent C/C++ coder should look at the alternatives and evaluate them for suitability.
+Task assigned to: <none yet> - could be Alex, Mihai, ...?
+=== Work in Progress ===
+**Infrastructure and procedures** for regularly releasing a new Mac client, at least in the next 1-3 years.
+(jenkins build slave, cloud-based OS X hosting)
+Task assigned to: Stefan (currently researching hosting options); might be expanded to Mike#1, Mihai, Alex and Mike#2
