See the original bug description. 442738 2 pfeldman 2011-07-26 21:48:23 -0700 I can see a clear possibility of this happening: WebInspector.HeapSnapshotRetainingPathsList.prototype.setDataSource has a guard preventing snapshotView from being assigned: if (this._nodeIndex === nodeIndex) return; subsequent refresh call will hit the problem described. 442797 3 mnaganov 2011-07-27 02:11:18 -0700 Yes, it can be reproduced by changing the current value of the "Paths from the selected object" with no heap object previously selected. 442798 4 102109 mnaganov 2011-07-27 02:14:31 -0700 Created attachment 102109 patch 442806 5 102109 webkit.review.bot 2011-07-27 02:37:47 -0700 Comment on attachment 102109 patch Attachment 102109 did not pass chromium-ews (chromium-xvfb): Output: http://queues.webkit.org/results/9249743 New failing tests: fast/canvas/webgl/framebuffer-test.html 442820 6 mnaganov 2011-07-27 03:03:26 -0700 Manually committed http://trac.webkit.org/changeset/91829 Web Inspector: [Chromium] REGRESSION: Uncaught TypeError: Cannot read property 'isTracingToWindowObjects' of undefined https://bugs.webkit.org/show_bug.cgi?id=65213 Reviewed by Pavel Feldman. * inspector/front-end/DetailedHeapshotView.js: (WebInspector.HeapSnapshotRetainingPathsList.prototype.refresh): 102109 2011-07-27 02:14:31 -0700 2011-07-27 02:37:47 -0700 patch patch-65213 text/plain 1283 mnaganov ZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJDb3JlL0NoYW5nZUxvZyBiL1NvdXJjZS9XZWJDb3JlL0No YW5nZUxvZwppbmRleCBkMGI1YmU5Li4wNjcxMzQ4IDEwMDY0NAotLS0gYS9Tb3VyY2UvV2ViQ29y ZS9DaGFuZ2VMb2cKKysrIGIvU291cmNlL1dlYkNvcmUvQ2hhbmdlTG9nCkBAIC0xLDMgKzEsMTMg QEAKKzIwMTEtMDctMjcgIE1pa2hhaWwgTmFnYW5vdiAgPG1uYWdhbm92QGNocm9taXVtLm9yZz4K KworICAgICAgICBXZWIgSW5zcGVjdG9yOiBbQ2hyb21pdW1dIFJFR1JFU1NJT046IFVuY2F1Z2h0 IFR5cGVFcnJvcjogQ2Fubm90IHJlYWQgcHJvcGVydHkgJ2lzVHJhY2luZ1RvV2luZG93T2JqZWN0 cycgb2YgdW5kZWZpbmVkCisgICAgICAgIGh0dHBzOi8vYnVncy53ZWJraXQub3JnL3Nob3dfYnVn LmNnaT9pZD02NTIxMworCisgICAgICAgIFJldmlld2VkIGJ5IE5PQk9EWSAoT09QUyEpLgorCisg ICAgICAgICogaW5zcGVjdG9yL2Zyb250LWVuZC9EZXRhaWxlZEhlYXBzaG90Vmlldy5qczoKKyAg ICAgICAgKFdlYkluc3BlY3Rvci5IZWFwU25hcHNob3RSZXRhaW5pbmdQYXRoc0xpc3QucHJvdG90 eXBlLnJlZnJlc2gpOgorCiAyMDExLTA3LTI2ICBNYXJrIEhhaG5lbmJlcmcgIDxtaGFobmVuYmVy Z0BhcHBsZS5jb20+CiAKICAgICAgICAgUmVmYWN0b3IgYXV0b21hdGljYWxseSBnZW5lcmF0ZWQg SlMgRE9NIGJpbmRpbmdzIHRvIHJlcGxhY2Ugb3BlcmF0b3IgbmV3IHdpdGggc3RhdGljIGNyZWF0 ZSBtZXRob2RzCmRpZmYgLS1naXQgYS9Tb3VyY2UvV2ViQ29yZS9pbnNwZWN0b3IvZnJvbnQtZW5k L0RldGFpbGVkSGVhcHNob3RWaWV3LmpzIGIvU291cmNlL1dlYkNvcmUvaW5zcGVjdG9yL2Zyb250 LWVuZC9EZXRhaWxlZEhlYXBzaG90Vmlldy5qcwppbmRleCBhYmU3NTE0Li4xMmJkMTI1IDEwMDY0 NAotLS0gYS9Tb3VyY2UvV2ViQ29yZS9pbnNwZWN0b3IvZnJvbnQtZW5kL0RldGFpbGVkSGVhcHNo b3RWaWV3LmpzCisrKyBiL1NvdXJjZS9XZWJDb3JlL2luc3BlY3Rvci9mcm9udC1lbmQvRGV0YWls ZWRIZWFwc2hvdFZpZXcuanMKQEAgLTQ1MSw3ICs0NTEsOCBAQCBXZWJJbnNwZWN0b3IuSGVhcFNu YXBzaG90UmV0YWluaW5nUGF0aHNMaXN0LnByb3RvdHlwZSA9IHsKIAogICAgIHJlZnJlc2g6IGZ1 bmN0aW9uKCkKICAgICB7Ci0gICAgICAgIHRoaXMuX3Jlc2V0UGF0aHMoKTsKKyAgICAgICAgaWYg KHRoaXMuc25hcHNob3RWaWV3KQorICAgICAgICAgICAgdGhpcy5fcmVzZXRQYXRocygpOwogICAg IH0sCiAKICAgICByZXNldDogZnVuY3Rpb24oKQo=
