Dear all,
the X2Go project is proud to announce a new release of the X2Go
component ,,python-x2go''.
New gains of this version of ,,python-x2go'' are:
o HTTP X2Go Session Broker support
o Telekinesis / mTelePlayer support (requires X2Go Server
>= 4.1.0.0)
o Selection of clipboard mode (bidirectional, server->client
client->server)
o More exception catching when some error occurs during
a running session / connected session
o Great improvements concerning session cleanup
o Require that X2Go Server commands are in $PATH
o Handle duplicate session profile names gracefully
o Deepen the undetstanding of SSH forwarding tunnels
o Several pulseaudio fixes for Windows (thanks to Michael
DePaulo!!!)
o Various other fixes around stability

[ Mike Gabriel ]
* New upstream version (0.5.0.0):
- Split up session profile backend into generic and storage specific
parts.
- Fully rework backend concept in Python X2Go. Breaks compatibility
with earlier versions of Python X2Go concerning backends (probably
not really used by third-party products, if at all).
- Fix setting default values in X2GoClientXConfig class.
- Default to xdg-open as default PDF viewer command.
- Provide session profile backend for a http broker.
- Make session profile backends more unicode robust.
- X2GoSessionProfile.get_server_hostname must return unicode objects.
- Speed-optimize session profile ID <-> name mapping.
- Handle injection of PKey (Paramiko SSH key) objects for authentication
from the broker session profiles backend.
- Allow catching "connection refused" errors while talking to an X2Go
Session Broker (X2GoBrokerConnectionException).
- Support cookie based authentication against a http(s) session broker.
- On Windows: Improve debugging when a new X-Server port has to be
allocated.
- Capture broker connection problems during selectsession calls to the
broker via a HOOK method.
- Allow user interaction via a HOOK if broker connection problems occur.
- Handle broker setups that don't require credentials. Connection can
be established simply by leaving the password (and authid) empty.
- Fix detection of matching path names in X2GoIniFiles.
- Make sure X2GoClientXConfig config file really gets written to disk
(after we changed the internas of X2GoIniFile for this new
major release).
- Rename hook method HOOK_no_known_xserver_found to
HOOK_no_installed_xservers_found. Call this new hook if no installed
X-Servers could be found on the system.
- Only check running X-Servers that have the same WMI SessionId as the
current X2Go application.
- Session profiles: default value type for exports session profile option
is an empty dictionary.
- Make X2GoClient's constructor aware of non-usable X-Server ports.
- Windows: Fix crash while attempting to find the session window.
- Support SSH proxy autologin feature of X2Go Session Broker.
- Provide Telekinesis support in Python X2Go.
- Stop manipulating session profiles in X2GoSshProxy class. Esp. stop
manipulating session profiles with deprecated session options.
- Type-hardening of X2GoSshProxy class. Accept hosts as list and strings.
If hosts are given as a list, a random list element will be taken as
host (for connecting and for the SSH proxy tunnel setup).
- Type-hardening of X2GoControlSession class's C{connect()} method.
Handle hostnames that come in as lists gracefully.
- Don't construct the sshproxy_tunnel parameter in x2go/utils.py. Leave
that to higher level classes that know more about X2Go internals.
- Add support for a subsystem string when setting up port forwarding
tunnels.
- Use gevent to spawn the TeKi client start-up process (instead
of waiting
for it to return).
- Provide support for new session parameter: clipboard. (Fixes: #508).
- Split up NX output and NX errors into two separate files.
- Silent ignore it if we cannot detect the local Xlib.display.Display()
instance (happens with polyinstantiated /tmp dirs).
- Don't start telekinesis client if not support server-side.
Don't attempt
at starting telekinesis client, if it is not installed.
- Disallow server-side users to override X2Go Server commands via
~/bin (or similar). (Fixes: #334).
- Handle non-available color depth in X2Go session name gracefully.
(Fixes: #358).
- Make sure that the x2gosuspend-session/x2goterminate-session commands
are sent to the X2Go Server before we take down the NX proxy
subprocess.
- Create a "session.window" file in the session directory. This
file for now
contains one line "ID:<window-id>". The file appears once a
session window
comes up (start/resume), and disappears once the session window closes
(suspend/terminate).
- Only enable Telekinesis client debugging if the logger instance is in
debug mode.
- Performance tests have shown, that enabling SSH compression is not a
good idea. NX should handle that instead (and does).
- Better control the startup bootstrap of the Telekinesis client
subsystem.
- Newly understand our own Paramiko/SSH forwarding tunnel code. Become
aware of handling multiple connects on the same tunnel.
- Rename LICENSE.txt to COPYING.
- Be more exact when detecting the NX proxy window id.
- On non-Windows platforms, enforce usage of the "ares" DNS resolver in
python-gevent (which is available since Python gevent 1.0~). (Fixes:
#588).
- Use Xlib to detect client-side destop geometry.
- For reverse port forwardings use IPv4 localhost address only.
- Assure proper NX Proxy cleanup when sessions suspends/
terminates.
- Assure proper Telekinesis client cleanup when sessions suspends/
terminates.
- Clean up terminal sessions properly when the clean_sessions() method
of the control session has got called.
- Don't use compression on TeKi sshfs mounts.
- Handle duplicate profile names gracefully (i.e. append a " (1)",
" (2)", ... to the session profile name). (Fixes: #500).
- Support server-side Telekinesis versions that ship their own
(teki-)sftpserver.
- Use session_name, not session_info object's __str__() method to obtain
session name (in X2GoTelekinesis).
- Handle socket errors on the reverse port forwarding tunnels more
gracefully.
- Handle sudden control session death during local folder sharing
gracefully.
- Don't choke on non-initialized SSH transport objects when initializing
SFTP client.
- Fix transport lock release in X2GoControlSession._x2go_sftp_put().
- Fix session lock release in various methods of the X2GoSession class.
- Release _share_local_folder_lock on instance X2GoTerminalSession
destruction.
- Detect non-installed sshfs (required for Telekinesis).
- X2GoControlSession: Don't mess with the associated_terminals dict if
the control session has already died away (i.e. been forcefully
disconnect).
- If the listsessions command detects a terminated or suspended session,
we have to destroy the corresponding X2GoTerminalSession() to trigger
a proper cleanup of that instance.
- Fix various hrefs in __doc__ strings.
- Fix creating/renaming/reconfiguring session profiles. Handle host
option properly (as list).
- Make sure we do a deepcopy of the default session profile parameters.
- Detect more exceptions in the requests module when
authenticating against a
session broker.
- Only convert the value of the export session profile option if not
already a Python dictionary.
- Capture X2GoControlSessionException occurrences during
client-side folder
sharing initializaation while starting/resuming a session.
- X2GoSessionRegistry: Don't report about sessions that have a not yet
fully assigned session name / profile name / profile id.
* debian/control:
+ Add dependencies: python-requests, python-simplejson.
+ Add R (python-x2go): sshfs.
+ Add S (python-x2go): telekinesis-client, mteleplayer-clientside.
+ Update D (python-x2go): python-paramiko (>= 1.15.1-0~). (Fixes: #602).
* python-x2go.spec:
+ Add dependencies: python-requests, python-simplejson.
+ Additionally adapt to building on openSUSE/SLES.
+ Add all python packages under R to BR (for epydoc run).
+ Update R for python-x2go: python-paramiko >= 1.15.1.

* New upstream version (0.5.0.0):
- Windows: Fix compatibility with PulseAudio 3.0 & later (Fixes: #532)
- Windows: Prevent high PulseAudio CPU usage on Windows XP by lowering
PulseAudio's CPU priority from "high" to "normal" on XP specifically.
Also do so on Windows Server 2003 (R2) (Fixes: #537)
