Status: RELEASE
Date: Thu, 19 Feb 2015 12:49:22 +0100
Fixes: 616 642 681 702 705 713 720 742 781 782
Changes: 
 x2goclient (4.0.3.2-0x2go1) RELEASED; urgency=medium
 .
   [ Oleksandr Shneyder ]
   * New upstream release (4.0.3.2):
     - Fix placement of session folders in session card column. (Fixes: #681).
     - Send empty message in x2gohelper to stop AppStarting cursor. (Fixes: #616).
     - Fix multiple creations of modmap timer (OS_DARWIN).
 .
   [ Mike Gabriel ]
   * New upstream release (4.0.3.2):
     - Add several info/error/debug log message while hunting down #702.
     - Use app.setQuitOnLastWindowClosed(false) for the X2Go Client QtApplication
       to assure that X2Go Client does not arbitrarily exit during a running
       session. This fixes X2Go Client crashes that occur when printing via
       the CUPS-X2Go printing mechanism with activate print dialog popup on
       incoming print jobs and minimized main window. (Fixes: #702).
     - Be more exact when reporting rev forwarding tunnel request failures to
       the GUI user. Include the purpose of the tunnel (NX, audio, foldersharing)
       in the error message.
     - Enable debugging in sshprocess.cpp and sshmasterconnection.cpp if
       --debug is given.
     - sshmasterconnection.cpp: Fix several grammar issues in error messages.
     - When sharing a client-side folder, do not write the SSH pub key to
       client-side authorized_keys file if the folder-to-be-shared does not
       exist on the client. (Partially solves #405).
     - Fix string concatenation/layout of error message when tunnel I/O errors
       occur.
     - Improve debugging/logging the SSH connections made by X2Go Client.
     - Fix quotes when calling remote commands via SSH (esp. allow same quoting/
       escaping style for libssh and openSSH+Krb based connections). (Fixes: #720).
     - FIXME: Disable PubkeyAuthentication _and_ PasswordAuthentication if
       GSSAPI authentication is activated. This is counter intuitive, though,
       and requires several other fixes in the authentication code.
   * x2goclient.spec:
     - Always set BuildRoot: parameter.
 .
   [ Sergey Savko ]
   * New upstream release (4.0.3.2):
     - Prevent passwordless re-logins into X2Go Session Broker if
       --broker-autologoff is used on the cmdline. (Fixes: #782).
     - Add new cmdline option --broker-noauth-use-session-username.
       When --broker-noauth is used, the broker does not know on behalf
       of which user to operate. This new option enables username syncing.
       When logging into X2Go Server, that username will be sent to the
       broker and be used for querying X2Go Broker Agents etc. (Fixes: #781).
 .
   [ Heinrich Schuchardt ]
   * New upstream release (4.0.3.2):
     - Base the layout dialogue "Session ID" (which shows up when starting a
       connection) on typographic points (instead of pixels). (Fixes: #713).
 .
   [ Jason Alavaliant ]
   * New upstream verson (4.0.3.2):
     - Use QUrl::toPercentEncoding() method to properly encode passwords sent
       to X2Go Session Broker. (Fixes: #705).
 .
   [ Mike DePaulo ]
   * New upstream release (4.0.3.2):
     - Windows: Win32 OpenSSL updates from 1.0.1j to 1.0.1L, which
       fixes the CVEs announced on 2015-01-08.
     - Windows: Cygwin OpenSSL updated from 1.0.1j-1 to 1.0.1k-1, which
       fixes the CVEs announced on 2015-01-08.
     - Windows: Bundle new version of VcXsrv: 1.15.2.2-xp+vc2013+x2go1.
       The differences from 1.15.2.1-xp+vc2013+x2go1 are that its bundled
       OpenSSL has been updated to 1.0.1k, and that xorg-server
       CVE-2014-8091..8103 have been fixed.
     - Windows: Update libssh from 0.6.3 to 0.6.4 (while maintaining
       Pageant support). This fixes CVE-2014-8132, which shouldn't
       affect x2goclient because x2goclient uses the SSH client
       functionality, not the SSH server functionality.
       0.6.4 also added 4 features related to ECDSA keys.
     - Windows: Fix compatibility with PulseAudio 6.0
     - Windows: Remove workaround for audio input with old versions of
       PulseAudio (calling parec once per second)
       (Fixes: #742)
       Thanks George Trakatelis (uom.edu.gr) for submitting this change.
     - Windows: Enable X2Go Client for Windows to build under VS2010 nmake
       (but not the VS2010 IDE due to a Qt4 Visual Studio Add-in limitation)
       Note that the official builds are still build under MinGW.
       (Fixes: #642)
       Thanks George Trakatelis (uom.edu.gr) for submitting this feature.
     - Windows: Make builds easier, and updating bundled dependencies
       easier, by adding copy-deps-win32.bat. It copies the exact
       version of each dependency (DLL, executable, data, folder, etc)
       from x2goclient-contrib.git.
 .
   [ Kaan Ozdincer ]
   * New upstream version (4.0.3.2):
     - Add Turkish translation file.

Subject: Executing parec seems unnecessary now that X2Go Client for Windows 4.0.3.0 uses PulseAudio 5.0

Date: Wed, 14 Jan 2015 21:05:46 +0200

[Message part 4 (text/plain, inline)]

Package: x2goclient
Version: 4.0.3.0

When trying to figure out why I get 
'Object::connect: No such slot ONMainWindow::slotSndTunOk(int)' 
in the debugging output of X2Go Client for Windows 4.0.3.0, 
I bumped onto a common error: 
Argument mismatch between function call and function definition. 
That prevents slotSndTunOk() from ever executing. 

slotStartParec() depends on slotSndTunOk() to execute parec. 
Executing parec was needed due to a PulseAudio's bug as explained in 
http://x2go-dev.x2go.narkive.com/wNgRoxTO/parec

One peculiar thing is that after fixing that mismatch, 
which enabled parec to execute, 
x2goclient became extremely sluggish. 
The only way to revert things back to normal 
was to prevent parec from ever executing. 
It seems that parec in not needed now that X2Go Client uses PulseAudio 5.0.

The attached patch saves x2goclient from calling slotStartParec() 
once per second unnecessarily.
