149532 2006-09-29 09:06 0000 vino-server uses 100% CPU occationally after connecting with VNC 2006-10-09 07:42:01 0000 1 1 1 Unclassified Gentoo Linux GNOME 2006.1 x86 Linux RESOLVED FIXED http://librarian.launchpad.net/1902787/vino-ubuntu.patch P2 normal --- 1 dubel@ufl.edu gnome@gentoo.org dubel@ufl.edu dubel@ufl.edu 2006-09-29 09:06:47 0000 I'm using Gnome's included VNC server (vino-server) to allow remote access from VNC (usually realvnc on windows). Occationally after disconnecting, vino-server CPU usage on the remote (vino-server) machine goes to 100%. It doesn't happen all of the time, and it's difficult to duplicate. There are no error messages in the process. Killing vino-server fixes the issue until next usage. While I couldn't find a related bug in the gentoo forums, I did see the same issue on an ubuntu forums: https://launchpad.net/distros/ubuntu/+source/vino/+bug/31037 There is a suggested patch that fixes the problem by not including clients "on hold" in the GTK main loop. I am weary to use this patch on my system, since it is a different distribution and I have limited experience with patches. I have experienced this bug for over a year, through many system updates. I still find the vino-server process eating 100% CPU occationally after disconnect. Can the patch be adapted for gentoo? Is is the same issue? dubel@ufl.edu 2006-09-29 09:10:43 0000 Created an attachment (id=98383) Patch found on an ubuntu forum (author Gary Coady) leio@gentoo.org 2006-09-29 09:17:04 0000 GNOME Upstream bug for this is http://bugzilla.gnome.org/show_bug.cgi?id=332011 (forwarded from the Ubuntu one). I have experienced the problem myself too. It happens after you get the password wrong. As a workaround I have killed the vino-server over ssh (while VNC is tunnelled through ssh anyway for me), restarted it over ssh (background + disown if necessary) and tried to get the password right on a new try, to not have to do it all again :) Upstream seems to find the patch suitable for commit after identation fixes, but I'm not sure what's up with their responsiveness (on that bug, and last vino release being 2.3.5...) I think we should try the patch out and go with it if it's fine. leio@gentoo.org 2006-10-09 07:42:01 0000 The GNOME release team picked the package up, committed gentoo provided 3 patches and the 100% CPU bug fixing patch and released 2.16.0. I have added it to the tree in ~arch, and tested that it fixes the CPU hogging problem after invalid password for me. 98383 2006-09-29 09:10 0000 Patch found on an ubuntu forum (author Gary Coady) vino-ubuntu.patch text/plain LS0tIHZpbm8tMi4xMy41L2RlYmlhbi9jaGFuZ2Vsb2cNCisrKyB2aW5vLTIuMTMuNS9kZWJpYW4v Y2hhbmdlbG9nDQpAQCAtMSwzICsxLDEwIEBADQordmlubyAoMi4xMy41LTB1YnVudHU1KSBkYXBw ZXI7IHVyZ2VuY3k9bG93DQorDQorICAqIFRoZSBJTyBzb2NrZXQgZm9yIGNsaWVudHMgb24gaG9s ZCBzaG91bGQgbm90IGJlIGluY2x1ZGVkIGluIHRoZQ0KKyAgICBHVEsgbWFpbiBsb29wLiBVYnVu dHU6ICMzMTAzNw0KKw0KKyAtLSBHYXJ5IENvYWR5ICZsdDtnYXJ5QGx5cmFudGhlLm9yZyZndDsg IEZyaSwgMzEgTWFyIDIwMDYgMTg6MTU6MTggKzAxMDANCisNCiB2aW5vICgyLjEzLjUtMHVidW50 dTQpIGRhcHBlcjsgdXJnZW5jeT1sb3cNCiANCiAgICogZGViaWFuL3J1bGVzOiBBZGQgLVdsLC0t YXMtbmVlZGVkIHRvIENGTEFHUyB0byBnZXQgcmlkIG9mIGEgbG90IG9mIHVzZWxlc3MNCm9ubHkg aW4gcGF0Y2gyOg0KdW5jaGFuZ2VkOg0KLS0tIHZpbm8tMi4xMy41Lm9yaWcvc2VydmVyL3Zpbm8t c2VydmVyLmMNCisrKyB2aW5vLTIuMTMuNS9zZXJ2ZXIvdmluby1zZXJ2ZXIuYw0KQEAgLTIwMSwz OSArMjAxLDYgQEANCiAgIHJldHVybiBUUlVFOw0KIH0NCiANCi1zdGF0aWMgdm9pZA0KLXZpbm9f c2VydmVyX3NldF9jbGllbnRfb25faG9sZCAoVmlub1NlcnZlciAgICAgICAgICAgICpzZXJ2ZXIs DQotCQkJCVZpbm9TZXJ2ZXJDbGllbnRJbmZvICAqY2xpZW50LA0KLQkJCQlnYm9vbGVhbiAgICAg ICAgICAgICAgIG9uX2hvbGQpDQotew0KLSAgcmZiQ2xpZW50UHRyIHJmYl9jbGllbnQgPSBjbGll bnQtJmd0O3JmYl9jbGllbnQ7DQotDQotICBkcHJpbnRmIChSRkIsICJTZXR0aW5nIGNsaWVudCAn JXMnIG9uIGhvbGQ6ICVzXG4iLA0KLQkgICByZmJfY2xpZW50LSZndDtob3N0LCBvbl9ob2xkID8g Iih0cnVlKSIgOiAiKGZhbHNlKSIpOw0KLQ0KLSAgcmZiX2NsaWVudC0mZ3Q7b25Ib2xkID0gb25f aG9sZDsNCi0NCi0gIC8qIFdlIGRvbid0IHByb2Nlc3MgYW55IHBlbmRpbmcgZGF0YSBmcm9tIGFu IGNsaWVudCB3aGljaCBpcw0KLSAgICogb24gaG9sZCwgc28gZG9uJ3QgbGV0IGl0IHN0YXJ2ZSB0 aGUgcmVzdCBvZiB0aGUgbWFpbmxvb3AuDQotICAgKi8NCi0gIGdfc291cmNlX3NldF9wcmlvcml0 eSAoZ19tYWluX2NvbnRleHRfZmluZF9zb3VyY2VfYnlfaWQgKE5VTEwsIGNsaWVudC0mZ3Q7aW9f d2F0Y2gpLA0KLQkJCSBvbl9ob2xkID8gR19QUklPUklUWV9MT1cgOiBHX1BSSU9SSVRZX0RFRkFV TFQpOw0KLQ0KLSAgaWYgKCFvbl9ob2xkKQ0KLSAgICB7DQotICAgICAgaWYgKCFjbGllbnQtJmd0 O3VwZGF0ZV90aW1lb3V0KQ0KLQljbGllbnQtJmd0O3VwZGF0ZV90aW1lb3V0ID0gZ190aW1lb3V0 X2FkZCAoNTAsDQotCQkJCQkJKEdTb3VyY2VGdW5jKSB2aW5vX3NlcnZlcl91cGRhdGVfY2xpZW50 X3RpbWVvdXQsDQotCQkJCQkJcmZiX2NsaWVudCk7DQotICAgIH0NCi0gIGVsc2UNCi0gICAgew0K LSAgICAgIGlmIChjbGllbnQtJmd0O3VwZGF0ZV90aW1lb3V0KQ0KLQlnX3NvdXJjZV9yZW1vdmUg KGNsaWVudC0mZ3Q7dXBkYXRlX3RpbWVvdXQpOw0KLSAgICAgIGNsaWVudC0mZ3Q7dXBkYXRlX3Rp bWVvdXQgPSAwOw0KLSAgICB9DQotfQ0KLQ0KIHN0YXRpYyBpbmxpbmUgZ2Jvb2xlYW4NCiBtb3Jl X2RhdGFfcGVuZGluZyAoaW50IGZkKQ0KIHsNCkBAIC0yNTcsNiArMjI0LDUxIEBADQogICByZXR1 cm4gdmlub19zZXJ2ZXJfdXBkYXRlX2NsaWVudCAocmZiX2NsaWVudCk7DQogfQ0KIA0KK3N0YXRp YyB2b2lkDQordmlub19zZXJ2ZXJfc2V0X2NsaWVudF9vbl9ob2xkIChWaW5vU2VydmVyICAgICAg ICAgICAgKnNlcnZlciwNCisJCQkJVmlub1NlcnZlckNsaWVudEluZm8gICpjbGllbnQsDQorCQkJ CWdib29sZWFuICAgICAgICAgICAgICAgb25faG9sZCkNCit7DQorICByZmJDbGllbnRQdHIgcmZi X2NsaWVudCA9IGNsaWVudC0mZ3Q7cmZiX2NsaWVudDsNCisNCisgIGRwcmludGYgKFJGQiwgIlNl dHRpbmcgY2xpZW50ICclcycgb24gaG9sZDogJXNcbiIsDQorCSAgIHJmYl9jbGllbnQtJmd0O2hv c3QsIG9uX2hvbGQgPyAiKHRydWUpIiA6ICIoZmFsc2UpIik7DQorDQorICByZmJfY2xpZW50LSZn dDtvbkhvbGQgPSBvbl9ob2xkOw0KKw0KKyAgaWYgKG9uX2hvbGQpDQorICB7DQorICAgIGlmIChj bGllbnQtJmd0O2lvX3dhdGNoKQ0KKyAgICB7DQorICAgICAgZ19zb3VyY2VfcmVtb3ZlKGNsaWVu dC0mZ3Q7aW9fd2F0Y2gpOw0KKyAgICAgIGNsaWVudC0mZ3Q7aW9fd2F0Y2ggPSAwOw0KKyAgICB9 DQorDQorICAgIGlmIChjbGllbnQtJmd0O3VwZGF0ZV90aW1lb3V0KQ0KKyAgICB7DQorICAgICAg Z19zb3VyY2VfcmVtb3ZlIChjbGllbnQtJmd0O3VwZGF0ZV90aW1lb3V0KTsNCisgICAgICBjbGll bnQtJmd0O3VwZGF0ZV90aW1lb3V0ID0gMDsNCisgICAgfQ0KKyAgfQ0KKyAgZWxzZQ0KKyAgew0K KyAgICBpZiAoIWNsaWVudC0mZ3Q7aW9fd2F0Y2gpDQorICAgIHsNCisgICAgICBjbGllbnQtJmd0 O2lvX3dhdGNoID0gZ19pb19hZGRfd2F0Y2ggKGNsaWVudC0mZ3Q7aW9fY2hhbm5lbCwNCisJCQkJ CUdfSU9fSU58R19JT19QUkksDQorCQkJCQkoR0lPRnVuYykgdmlub19zZXJ2ZXJfY2xpZW50X2Rh dGFfcGVuZGluZywNCisJCQkJCXJmYl9jbGllbnQpOw0KKyAgICB9DQorDQorICAgIGlmICghY2xp ZW50LSZndDt1cGRhdGVfdGltZW91dCkNCisgICAgew0KKyAgICAgIGNsaWVudC0mZ3Q7dXBkYXRl X3RpbWVvdXQgPSBnX3RpbWVvdXRfYWRkICg1MCwNCisJCQkJCShHU291cmNlRnVuYykgdmlub19z ZXJ2ZXJfdXBkYXRlX2NsaWVudF90aW1lb3V0LA0KKwkJCQkJcmZiX2NsaWVudCk7DQorICAgIH0N CisgIH0NCit9DQorDQogc3RhdGljIGVudW0gcmZiTmV3Q2xpZW50QWN0aW9uDQogdmlub19zZXJ2 ZXJfaGFuZGxlX25ld19jbGllbnQgKHJmYkNsaWVudFB0ciByZmJfY2xpZW50KQ0KIHsNCkBAIC0y ODAsMTEgKzI5Miw2IEBADQogDQogICBjbGllbnQtJmd0O2lvX2NoYW5uZWwgPSBnX2lvX2NoYW5u ZWxfdW5peF9uZXcgKHJmYl9jbGllbnQtJmd0O3NvY2spOw0KIA0KLSAgY2xpZW50LSZndDtpb193 YXRjaCA9IGdfaW9fYWRkX3dhdGNoIChjbGllbnQtJmd0O2lvX2NoYW5uZWwsDQotCQkJCSAgICAg R19JT19JTnxHX0lPX1BSSSwNCi0JCQkJICAgICAoR0lPRnVuYykgdmlub19zZXJ2ZXJfY2xpZW50 X2RhdGFfcGVuZGluZywNCi0JCQkJICAgICByZmJfY2xpZW50KTsNCi0NCiAgIHNlcnZlci0mZ3Q7 cHJpdi0mZ3Q7Y2xpZW50cyA9IGdfc2xpc3RfcHJlcGVuZCAoc2VydmVyLSZndDtwcml2LSZndDtj bGllbnRzLCBjbGllbnQpOw0KIA0KICAgdmlub19zZXJ2ZXJfc2V0X2NsaWVudF9vbl9ob2xkIChz ZXJ2ZXIsIGNsaWVudCwgc2VydmVyLSZndDtwcml2LSZndDtvbl9ob2xkKTsNCg==
