[Message part 1 (text/plain, inline)]

Package: x2goclient 
Version: 4.1.1.1 

x2goserver logs are filled with these: 
Dec 11 12:05:08 server pulseaudio[25146]: [pulseaudio] main.c: User-configured server at localhost:48283, refusing to start/autospawn.

Dec 11 12:05:19 server pulseaudio[25185]: [pulseaudio] main.c: User-configured server at localhost:48283, refusing to start/autospawn. 

ssh is using ssh pipe to connect to the pulseaudio server of the client. When a session is disconnected this pipe is cut and apps using pulseaudio clients are trying respawn the pulseaudio found in x2goserver which they should not do. The following patch tells them not to try that and the issue is fixed.

   [ Oleksandr Shneyder ]
   * New upstream version (4.1.2.2):
     - Add SSH instruction to list of errors if keyboard-interactive auth has
       failed.
     - Add new brocker feature. Broker can send to client some configuration in
       the section START_CLIENT_CONFIG - END_CLIENT_CONFIG. For the moment is
       supported option events=bool. If true, client sending to broker events:
       CONNECTING, CONNECTED, SUSPENDING, TERMINATING, FINISHED. It's not a real
       session state, but rather the state of X2Go Client.
     - Save session command in resumingSession.command.
     - Send in broker event the duration of session on client.
     - If client is configured to send events, the broker can ask client to send
       ALIVE events. To do this, broker should send config option "liveevent"
       (int).
       It means, if liveevent=10, client will send ALIVE event to broker every
       10 seconds when the client connected to X2Go Session.
     - Broker can send to client command to suspend or terminate the session as
       an answer to the client event message. For this broker should send to
       client SUSPEND ID or TERMINATE ID.
     - Client now sends "login" parameter to the broker when executing task
       "selectsession". Before client just sent a username on the broker and it
       was imposiible to find out user name on X2Go server, which is not always
       the same as broker username. This won't break a compatibility with
       previous broker as they just will ignore this parameter.
     - X2Gokdrive support for X2GoClient.
     - Fix authentification on http broker when sending event.
     - Fix resuming sessions on multiple servers.
     - Initializing sessionId, command and display for direct RDP to complay
       with standard sessions.
     - Direct RDP sesion send to broker event CONNECTED instead of CONNECTING at
       start of RDP client.
     - Fixing setting correct session command when resuming the session.
     - Don't exit if sending event to http broker has failed.
     - If using x2go broker and ssh proxy check for the option
       "usebrokeruserforproxy" in the session file. If it's "true", use the same
       username for the proxy as broker login.
     - Broker can send to client the number of suspended and running sessions
       for each session type.
       Client will display this information to user on session button.
     - update copyright years in about dialog.
     - Do not show password in debug output of HTTP broker.
     - Fix crashing if the path for automount in the session config file in
       wrong format. Supporting both Windows and Linux path in automount format.
       Check if path exists before mounting.
     - Do not show Pulseaudio warning on Windows, if Pulseaudio is disabled in
       settings or by command line.
     - Improve request handling in HTTP broker.
     - Add possibility to suspend and terminate sessions from session selection
       dialog in broker mode.
     - Do not delete session from list if terminating of session is canceled.

   [ Mihai Moldovan ]
   * New upstream version (4.1.2.2):
     - src/printwidget.cpp: add QButtonGroup include, fixes compile errors with
       Qt 5.11+. Fixes: #1307.
     - macbuild.sh: switch to bundling PulseAudio 12.1 since it's now available
       in MacPorts.
     - x2goclient.pro: detect libssh and libssh_threads via pkgconfig on
       UNIX-based platforms. libssh_threads is optional if the libssh version
       is high enough.
     - x2goclient.pro: let static Linux configuration override the new
       pkgconfig-based libssh usage.
     - x2goclient.pro: make system a non-variable call.
     - x2goclient.pro: fix qmake control flow for libssh logic, we really
       wanted to use else if for the Windows section and have the general else
       section being the general fallback.
     - x2goclient.pro: fix quoting issue in system() call. Qmake's quoting
       rules are really weird.
     - macbuild.sh: switch to bundling PulseAudio 12.2 since it's now available
       in MacPorts.
     - res/i18n/x2goclient_cs.ts: whitespace and other fixups.
     - src/x2goclient.cpp: change HTTP to HTTPS links where needed.
     - src/x2goclient.cpp: do not spawn UNIX cleanup helper if arguments that
       let X2Go Client terminate right away have been passed. More work is
       needed here, but that should cover the most basic bits.
     - src/onmainwindow.{cpp,h}: remove left-over references to agentCheckTimer
       and slotCheckAgentProcess ().
     - src/onmainwindow.cpp: fix various broken qCritical () calls.
     - src/{onmainwindow.{cpp,h},{sshmasterconnection,help}.cpp}: let users
       control libssh debugging via the new parameters --libssh-debug and
       --libssh-packetlog. Properly document the new switches and their
       implications.
     - src/sshmasterconnection.cpp: drop DEBUG preprocessor conditional blocks.
       We have never actually disabled it and x2goDebug () will not write out
       anything if debugging has not been requested, so we already have a soft
       condition check for every x2goDebug () call.
     - src/x2goclient.cpp: do not use std::array since that's a C++11 feature,
       just live with plain C arrays for now.
     - x2goclient.pro: fix libssh_threads logic again. Ubuntu Bionic/18.04
       ships a pre-release version of 0.8.0, which is tagged as that version,
       but really based upon 0.7.x and still has/needs a libssh_threads
       library. Big "Wat?" to you, Canonical. Fixes: #1320.
     - src/x2goclient.cpp: fix array length calculation.
     - Windows: Update PuTTY from 0.70 to 0.71. Fixes quite a list of issues
       discovered through the EU-funded bug bounty programme. Not all are
       relevant to X2Go Client.
     - Windows: upgrade bundled VcXsrv to 1.20.1.4.
     - src/sshmasterconnection.cpp: use info (protocol) log level with
       --libssh-debug and debug (packet) log level with --libssh-packetlog.
     - src/sshmasterconnection.cpp: fix compiler warning due to mismatching
       argument with older libssh versions.
     - Makefile: clear out LDFLAGS, add new (cleared) LIBS variable and pass
       down as QMAKE_LIBS. The previous behavior was leading to compile
       failures on arm64 machines (albeit only old distro versions,
       apparently), because QMAKE_LFLAGS is being put on the command line
       *before* the actual object files to be included/linked, which is an
       error for system libraries. Builds will still fail after this commit,
       but that's okay.
     - x2goclient.pro: add libraries that we always want to use on Linux
       correctly to LIBS and use a bigger catch clause. That should work much
       better, since linux-g++ and linux-g++-64 are x86-specific, while there
       are way more potentially useful targets like linux-aarch64-gnu-g++,
       clang, llvm, icc etc.
     - x2goclient.pro: while a linux scope seems to work fine with Qt5, Qt4
       doesn't recognize that, so add another linux-* catch.
     - Windows: add support for x3270-fonts, including adding a pretty nasty
       but necessary fonts.* file regeneration hook.
     - {x2goclient,help,onmainwindow}.cpp: implement new
       --bypass-cleanup-helper parameter.
     - src/onmainwindow.cpp: fix building with Qt 4.6, currently the latest
       version available in EPEL 6.
     - src/onmainwindow.cpp: unbreak builds by fixing syntax error.
     - src/onmainwindow.cpp: also unbreak old EPEL 6 builds.
     - src/onmainwindow.cpp: add (and prefer) non-compat-symlink scp server
       location for 64-bit-based Gentoo distros (17.1+ profiles). Fixes:
       #1393.
     - res/i18n/x2goclient_*.ts: replace changed source strings, no
       retranslations required.
     - src/httpbrokerclient.cpp: do not leak password length in debug output
       either.
     - src/sessionwidget.cpp: stop parsing proxy address as "host:port: if the
       address contains a colon. Fixes: #1418. We don't do this for the
       "normal" host address and this behavior clashes with IPv6 addresses. We
       COULD, theoretically, keep it, but that would require writing an
       arbitrary address parser. Too much effort for little gain.
     - src/onmainwindow.cpp: also remove proxy "host:port" parsing at connect
       time. Fixes: #1418.
     - macbuild.sh: switch to bundling PulseAudio 13.0 since it's now available
       in MacPorts.
     - src/onmainwindow.cpp: disable "left click" action on OS X/macOS. This
       platform always gets a left click event, even when right clicked. May
       sound weird first, but this behavior is consistent between all
       applications - tray icons can be clicked via either button and will
       always trigger a context menu. Let X2Go Client behave the same way.
     - src/sshprocess.cpp: strip ~/, ~user{,/}, ${HOME}{,/} and $HOME{,/} from
       destination paths in scp mode. Fixes: #1428. This was already necessary
       for pascp (PuTTY-based Windows solution for Kerberos support), but newer
       libssh versions with the CVE-2019-14889 also interpret paths as literal
       strings.
     - src/SVGFrame.cpp: simplify implementation a lot. Only paint data onto
       the widget in the paintEvent () function. Drop setting a palette based
       upon the rendered SVG image, which has been very wrong to do from the
       beginning and only lead to visual glitches. Correctly repaint
       single-frame SVG files.
     - src/sshmasterconnection.cpp: work around lupdate warning by adding
       another block in the #else preprocessor branch.
     - res/i18n/x2goclient_*.ts: update translation files.
     - Windows: Update PuTTY from 0.71 to 0.73. Fixes another round of issues
       discovered through the EU-funded bug bounty programme and other security
       problems.
     - src/onmainwindow.cpp: stop PulseAudio from spamming logs after a client
       disconnects. Fixes: #1425. Patch based on one submitted by Ville
       Salmela.
     - src/onmainwindow.cpp: instead of searching for "sftp-binary", try to
       look for "sftp-server" in the Qt 5.x code path. Luckily this only
       affects cases where we bundle sftp-server (which we don't) or where
       sftp-server is actually part of $PATH (which it usually shouldn't be).
     - Windows: upgrade bundled VcXsrv to 1.20.6.0.
     - Windows: upgrade PulseAudio from 7.1 to 13.0.
     - Windows: remove libz. Was previously used by libzip, which has not been
       shipped for quite some time.
     - Windows: Update Win32 OpenSSL from 1.0.2n to 1.0.2u. Implicit.
     - Windows: Upgrade libssh from 0.7.4 to 0.9.3 (while maintaining Pageant
       support). Drop libssh_threads library not provided (or used) any longer.
     - x2goclient.pro: update comment mentioning that libssh does not provide
       pkgconfig files on non-UNIX/Windows platforms any longer and drop
       libssh_thread linkage.
     - res/i18n/x2goclient_nl.ts: add missing singular form to a multi-form
       entry.
     - res/i18n/x2goclient_cs.ts: fix up whitespace and mark actually finished
       translation string as such, also removing my previous comment.
     - res/i18n/x2goclient_nb_no.ts: fix up whitespace and typos.
     - res/i18n/x2goclient_de.ts: better translate UNIX cleanup helper and fix
       "X2Go Client" as "X2GoClient" globally.
     - misc: pre-release copyright update.
     - src/onmainwindow.cpp: update in-code copyright notice.
     - res/i18n/x2goclient_*.ts: update copyright notice in about dialog
       manually.
     - src/onmainwindow.cpp: add comment for translators encouraging them to
       add themselves to copyright notice.
     - res/i18n/x2goclient_*.ts: update after source code changes and comment
       addition.
     - res/i18n/x2goclient_*.ts: mark copyright translation string as
       unfinished for already translated languages (but Finnish) to alert
       translators of the new comment.
     - man/man1/x2goclient.1: pre-release date update.

   [ Ulrich Sibiller ]
   * New upstream release (4.1.2.2):
     - src/sshmasterconnection.cpp: close channel on failure in checkLogin ().
     - src/sshmasterconnection.{cpp,h}: skip checkLogin() if hostname starts
       with "!". Some special ssh proxies will not allow arbitrary commands.
       checkLogin() will break these sessions because it tries to run the echo
       command on the proxy. By specifying a "!" as the first character of the
       (proxy) hostname you can instruct x2goclient ot skip the checkLogin()
       call altogether. Note that this will break proxies that require you to
       change you password or some other type of interaction. As this is added
       to SshMasterConnection it is also valid to specify that for the server
       hostname although this is not very useful.
