[X2Go-Dev] Bug#723: Bug#723: x2go sessions insta-break with some GUI software (ROOT TBrowser)
Hi Mike, are you still there? We like X2Go very much - great work! Is there any chance to solve this problem in Vcxsrv? Or maybe give a possible reason for the problem, so that the ROOT programmers could think about a solution. I know it is a relatively small user group using ROOT together with X2Go Client for Windows, but I would be very glad to get it working without installing an old Vcxsrv version.

Some updates on this bug: I've tested several VcXsrv-Versions from http://code.x2go.org/releases/binary-win32/3rd-party/vcxsrv-modified-by-x2go-project/ The bug purely occurs with the more recent versions of VcXsrv - like 1.15.2.0 and 1.15.2.1 The bug does NOT occur with the older versions 1.14 (tested 1.14.3.2). So the bug is caused by changes made in VcXsrv from version 1.14 to 1.15. I used the debug version vcxsrv-debug.1.15.2.1-xp+vc2013+x2go1.installer.exe to receive the following trace of the SIGFAULT: Program received signal SIGSEGV, Segmentation fault. in memcpy () from C:\Temp\VcXsrv-Debug\msvcr120d.dll 0x5b4b3365 +0x01c5f3 0f 6f 0e movdqu (%esi),%xmm1 0x5b4b3369 +0x01c983 e9 10 sub$0x10,%ecx 0x5b4b336c +0x01cc8d 76 10 lea0x10(%esi),%esi 0x5b4b336f +0x01cf66 0f 7f 0f movdqa %xmm1,(%edi) 0x5b4b3373 +0x01d38d 7f 10 lea0x10(%edi),%edi 0x5b4b3376 +0x01d6eb e8jmp0x5b4b3360 memcpy+448 0x5b4b3378 +0x01d80f ba e1 02 bt $0x2,%ecx 0x5b4b337c +0x01dc73 0djae0x5b4b338b memcpy+491 0x5b4b337e +0x01de8b 06mov(%esi),%eax 0x5b4b3380 +0x01e083 e9 04 sub$0x4,%ecx 0x5b4b3383 +0x01e38d 76 04 lea0x4(%esi),%esi 0x5b4b3386 +0x01e689 07mov%eax,(%edi) 0x5b4b3388 +0x01e88d 7f 04 lea0x4(%edi),%edi 0x5b4b338b +0x01eb0f ba e1 03 bt $0x3,%ecx 0x5b4b338f +0x01ef73 11jae0x5b4b33a2 memcpy+514 0x5b4b3391 +0x01f1f3 0f 7e 0e movq (%esi),%xmm1 0x5b4b3395 +0x01f583 e9 08 sub$0x8,%ecx 0x5b4b3398 +0x01f88d 76 08 lea0x8(%esi),%esi 0x5b4b339b +0x01fb66 0f d6 0f movq %xmm1,(%edi) 0x5b4b339f +0x01ff8d 7f 08 lea0x8(%edi),%edi 0x5b4b33a2 +0x02028b 04 8d d8 34 4b 5b mov 0x5b4b34d8(,%ecx,4),%eax 0x5b4b33a9 +0x0209ff e0jmp*%eax 0x5b4b33ab +0x020bf7 c7 03 00 00 00test $0x3,%edi 0x5b4b33b1 +0x021175 15jne0x5b4b33c8 memcpy+552 0x5b4b33b3 +0x0213c1 e9 02 shr$0x2,%ecx 0x5b4b33b6 +0x021683 e2 03 and$0x3,%edx 0x5b4b33b9 +0x021983 f9 08 cmp$0x8,%ecx 0x5b4b33bc +0x021c72 2ajb 0x5b4b33e8 memcpy+584 SEGFAULT 0x5b4b33be +0x021ef3 a5rep movsl %ds:(%esi),%es:(%edi) ___ x2go-dev mailing list x2go-dev@lists.x2go.org http://lists.x2go.org/listinfo/x2go-dev

Hi Martin, On Mi 07 Jan 2015 19:33:42 CET, Babutzka, Martin (EKP) wrote: Package: x2goclient Version: 4.0.3.0 x2goserver-version: 4.0.1.18-0~949 running on Ubuntu 14.04.1 x2goclient-version: 4.0.3.0 running on Windows 7 We are experiencing a strange bug in the interplay of x2go with a component of the ROOT data analysis framework (https://root.cern.ch). Displaying GUI windows in the ROOT framework, shows them shortly and results in an immediate CRASH of the X2go connection with a Windows error vcxsrv.exe has stopped working and subsequent closure of all opened remote applications. Strangely the GUI window shows up when resuming the session in X2go. Running the ROOT GUI window from pure vcxsrv, Xming, Mobaxfire or similar Windows X-Server applications works flawlessly. It also worked previously with the baikal version of X2go. I admit this seems to be an exotic bug but there might be further graphical software affected which increases the severity of this bug. Steps to reproduce: - Install ROOT from the webpage or via apt-get install root-system-bin on the x2goserver - Run root on command line. - Open a TBrowser with the command TBrowser b After this the x2goclient slowly fills the session log with warnings of Proxy: WARNING! Handling data for finishing FD#6 channel ID#1. This bug is a kind of a show stopper for us because we need ROOT for scientific use. I would help to further track down the error and debug if I can get some hints where and how to start. Kind regards, Martin Is it possible to be granted access to a reference installation that shows the above describe behaviour? Esp. the fact, that resuming the crashed session gives me a bit of hope here. Also: do you know if your software uses the X11 bigrequests extension?

I've seen the exact same behavior, also with a Windows client, when I was running an older X2GoClient release and trying to run Chrome/Chromium. It would zap the session whenever certain menu items were clicked, x2goclient.exe/vcxsrv.exe would terminate with exactly the same error, and resuming the session after restarting all X2GoClient components (VcXSrv, PulseAudio, SSH) allowed one to continue - until the next crash. For me, switching to a newer client version that brought a newer VcXSrv helped, so maybe the issue is similar here. Of course, 4.0.3.0 is almost the newest version we have ... so maybe it would be worth a try with another X-Server, like the one from mingw maybe? I guess Mike#2 could offer some suggestions/advice here, CCing him so he takes notice. - -Stefan - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.22 (MingW32) iQEcBAEBAgAGBQJUrlnOAAoJEG7d9BjNvlEZlqAIAJawOG2cPy/llvoR+nWw4Srl e5jAjMA4viOdaDZP6IHCZCXKsaIUi+zGcshiPiFiFlPtxBXjqGSxCMzCFwjZOuVO EGGoa4wehuGhvuSFYkHfBSTbgWTPcRnc/MSHL8iJ4QceJvDTEN7DZ9AwLwdkkllV D6rVOp+TcoeBoW+2/kmo5UTTcMQOt2QukXFRylugbN8TirFP+yf4jcqR/jmS/JA8 Sp+mq5GznItRFBwWrBe31sMZ8w5J4S+fAd3ASflxdNbqt/YxxSZaTvzt8W1x29m3 LYSTjQWd0ReTL6/ruOAWXK9TESpwHD9UHaC9nnz7xfK7sIP1LrtnJ1IJSmVoy+g= =LLKa -END PGP SIGNATURE- ___ x2go-dev mailing list x2go-dev@lists.x2go.org http://lists.x2go.org/listinfo/x2go-dev
