Bug#302: Possible solution to #302 ?
by GZNG Tech 12 Jun '14

12 Jun '14

Control: tag -1 patch Hi, Putting the attached file into your "extensions/post-suspend.d" folder on the server... may solve #302 issues... On Ubuntu that would be an executable named "302_bug-fix" with the following full path: /usr/lib/x2go/extensions/post-suspend.d/302_bug-fix (On other distros just simply locate your "post-suspend.d" folder and put it there.. PS! Make sure its executable! (chmod 755). Its may be good to clean up all old sessions before you start a brand new and fresh session to test this fix. We were able to reliably reproduce fault/non-fault conditions and after applying this fix, we're seeing 100% success rates for session resume with pyhoca.... The source of the issue seem to be that the NX port reappears on the server within seconds of session suspension.... in a state where where its not ready for new incoming connections... (quite frankly it should not be available at all at this time, should it?) So either we're reconnecting to this "faulty" port or the fresh port fails to open due to the "old port" being in the way.... Either way NX fails to resume... The problem seem to be consistently occurring when rapidly suspending/resuming with pyhoca and if x2goclient experience abnormal/unclean disconnects that results in suspension. Either way this little perl script will clean up those stray NX ports by simply locating and connecting to them... (after which, the port closes, as it should.) If this indeed solves the #302 bug, this should probably move from extensions to being part of the suspend scripts.... but for cleanliness and admin-friendliness its easier to test it as an extension.... Let us know if this works for you! (btw: If the supportive subs are adopted to Utils.pm the script it self would become quite compact) Best Regards, -GZNGET

FYI: I am working with the PulseAudio devs on a Windows-specific cookie issue again
by Michael DePaulo 12 Jun '14

12 Jun '14

https://bugs.freedesktop.org/show_bug.cgi?id=75006#c16 Basically, the fact that PulseAudio ignores XDG_CONFIG_HOME and PULSE_COOKIE is a problem for everyone who uses or integrates PulseAduio. Tanu (the lead PulseAudio developer) submitted a set of 9 patches for this issue, but they changed the behavior of PulseAudio in such a way that breaks compatibility with x2goclient. My intention is for x2goclient master (4.0.2.1) for Windows to be able to work with PulseAudio 0.9.6, 1.1, 5.0 and master. Presumably, I'll just provide feedback on those patches, and Tanu will rework them. Or I'll make a safe Windows-specific change to x2goclient, like specifying PULSE_COOKIE. For those who don't know, x2goclient 4.0.2.0 works with 0.9.6, 1.1 and 5.0. (And versions in-between 1.1 and 5.0. We only ship 5.0 because there have been no Windows-specific Audio issues reported for 4.0.2.0.) Also, even before these 9 patches were applied, x2goclient no longer worked with pulseaudio master. I fixed that though with this commit: Once I made the parent commit, it was very easy to debug and fix. http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=6d3998f69cf9a7350e3… -Mike#2

Today, I have been in NX code for the whole day and I wonder, if I can do something for you to get the above issue fixed. I tested the above with this python snippet: """ #!/usr/bin/python # simple.py import sys from PyQt4 import QtGui app = QtGui.QApplication(sys.argv) widget = QtGui.QWidget() widget.resize(250, 150) widget.setWindowTitle('simple') widget.show() sys.exit(app.exec_()) """ and I don't bump into any problems as described above. Can you please: 1. get latest x2goagent/nxagent/libnx-x11 from our nightly builds[1] 2. re-test the above 3. if you get the same error, send me the python code that triggers the bug Greets, Mike PS: please wait for the current build of nx-libs to finish [2] [1] http://wiki.x2go.org/doku.php/wiki:development:nightly-builds [2] https://jenkins.x2go.org:8443/view/NX/ -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…
