It seems that this is some sort of unexpected re-entrancy. Will investigate. 1035077 1 burg 2014-09-13 13:20:19 -0700 Appears to be that we enter multiple event loop input extents when handling user inputs inside a nested run loop when the debugger is paused. This only happens when not capturing or replaying, AFAICT. We temporarily disable breakpoints before starting capturing, so this only seems to happen when neither capturing or replaying. During replay, we should never be starting run loop tasks while debugger is paused. 1037042 2 238611 burg 2014-09-24 15:16:17 -0700 Created attachment 238611 WIP 238611 2014-09-24 15:16:17 -0700 2014-09-24 15:16:17 -0700 WIP bug-133019-20140924151611.patch text/plain 2348 burg U3VidmVyc2lvbiBSZXZpc2lvbjogMTczODAyCmRpZmYgLS1naXQgYS9Tb3VyY2UvSmF2YVNjcmlw dENvcmUvQ2hhbmdlTG9nIGIvU291cmNlL0phdmFTY3JpcHRDb3JlL0NoYW5nZUxvZwppbmRleCA5 ZWIzMDUwMmM0MWQwZjQ0OTZjY2FmOWM3OGM0MmY3ZmUxZWQxNDNjLi5jMzhlNTUzNjdkM2QwZTg2 NWY0NTczMjRmNzU2N2MxMDVjYTdlMWZlIDEwMDY0NAotLS0gYS9Tb3VyY2UvSmF2YVNjcmlwdENv cmUvQ2hhbmdlTG9nCisrKyBiL1NvdXJjZS9KYXZhU2NyaXB0Q29yZS9DaGFuZ2VMb2cKQEAgLTEs MyArMSwyMSBAQAorMjAxNC0wOS0xMyAgQnJpYW4gSi4gQnVyZyAgPGJ1cmdAY3Mud2FzaGluZ3Rv bi5lZHU+CisKKyAgICAgICAgV2ViIFJlcGxheTogQVNTRVJUSU9OIEZBSUxFRDogd2l0aGluRXZl bnRMb29wSW5wdXRFeHRlbnQgIT0gbV93aXRoaW5FdmVudExvb3BJbnB1dEV4dGVudAorICAgICAg ICBodHRwczovL2J1Z3Mud2Via2l0Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9MTMzMDE5CisKKyAgICAg ICAgUmV2aWV3ZWQgYnkgTk9CT0RZIChPT1BTISkuCisKKyAgICAgICAgVGhpcyBhc3NlcnRpb24g aXMgc2xpZ2h0bHkgd3JvbmcgYmVjYXVzZSBpdCBkb2VzIG5vdCBhY2NvdW50IGZvciBuZXN0ZWQg cnVuIGxvb3BzLgorICAgICAgICBXZSBjYW4gYmUgd2l0aGluIHR3byBpbnB1dCBleHRlbnRzIHdo ZW4gYSBuZXN0ZWQgcnVuIGxvb3AgcHJvY2Vzc2VzIGFkZGl0aW9uYWwKKyAgICAgICAgdXNlciBp bnB1dHMgd2hpbGUgdGhlIGRlYnVnZ2VyIGlzIHBhdXNlZC4KKworICAgICAgICBUaGlzIHNob3Vs ZCBvbmx5IGJlIHRoZSBjYXNlIHdoZW4gZXhlY3V0aW9uIGlzIGJlaW5nIG5laXRoZXIgY2FwdHVy ZWQgb3IKKyAgICAgICAgcmVwbGF5ZWQuIFRoZSBkZWJ1Z2dlciBzaG91bGQgbm90IHBhdXNlIHdo ZW4gY2FwdHVyaW5nLCBhbmQgd2Ugc2hvdWxkIG5vdCByZXBsYXkKKyAgICAgICAgZXZlbnQgbG9v cCBpbnB1dHMgd2hpbGUgaW4gYSBuZXN0ZWQgcnVuIGxvb3AuCisKKyAgICAgICAgKiByZXBsYXkv SW5wdXRDdXJzb3IuaDoKKyAgICAgICAgKEpTQzo6SW5wdXRDdXJzb3I6OnNldFdpdGhpbkV2ZW50 TG9vcElucHV0RXh0ZW50KTogRml4IHRoZSBhc3NlcnRpb24uCisKIDIwMTQtMDgtMTkgIEJyaWFu IEouIEJ1cmcgIDxidXJnQGNzLndhc2hpbmd0b24uZWR1PgogCiAgICAgICAgIFdlYiBSZXBsYXk6 IENoZWNrIGV2ZW50IGxvb3AgZXh0ZW50cyBkdXJpbmcgcmVwbGF5aW5nCmRpZmYgLS1naXQgYS9T b3VyY2UvSmF2YVNjcmlwdENvcmUvcmVwbGF5L0lucHV0Q3Vyc29yLmggYi9Tb3VyY2UvSmF2YVNj cmlwdENvcmUvcmVwbGF5L0lucHV0Q3Vyc29yLmgKaW5kZXggMmY0MDA0MGJmNTMxYjI5NjEzOWVh NmYyNWU5OTBlNmQ2MWNkODc2ZC4uNWMyYTg1ZTlhMDM3Y2I3ZDI1MmI4ZGZhNDg0Y2YzZGM4NmQ2 ZDQ5MSAxMDA2NDQKLS0tIGEvU291cmNlL0phdmFTY3JpcHRDb3JlL3JlcGxheS9JbnB1dEN1cnNv ci5oCisrKyBiL1NvdXJjZS9KYXZhU2NyaXB0Q29yZS9yZXBsYXkvSW5wdXRDdXJzb3IuaApAQCAt NTIsOSArNTIsMTEgQEAgcHVibGljOgogCiAgICAgdm9pZCBzZXRXaXRoaW5FdmVudExvb3BJbnB1 dEV4dGVudChib29sIHdpdGhpbkV2ZW50TG9vcElucHV0RXh0ZW50KQogICAgIHsKLSAgICAgICAg Ly8gV2UgY2Fubm90IGVudGVyIG1vcmUgdGhhbiBvbmUgZXh0ZW50IGF0IGEgdGltZSwgc2luY2Ug dGhleSByZXByZXNlbnQKLSAgICAgICAgLy8gYSBzaW5nbGUgcnVuIGxvb3AncyB3b3JrIG9uIGJl aGFsZiBvZiB0aGUgUGFnZS4KLSAgICAgICAgQVNTRVJUKHdpdGhpbkV2ZW50TG9vcElucHV0RXh0 ZW50ICE9IG1fd2l0aGluRXZlbnRMb29wSW5wdXRFeHRlbnQpOworICAgICAgICAvLyBXZSBjYW4g YmUgd2l0aGluIHR3byBpbnB1dCBleHRlbnRzIHdoZW4gYSBuZXN0ZWQgcnVuIGxvb3AKKyAgICAg ICAgLy8gcHJvY2Vzc2VzIGFkZGl0aW9uYWwgdXNlciBpbnB1dHMgd2hpbGUgdGhlIGRlYnVnZ2Vy IGlzIHBhdXNlZC4KKyAgICAgICAgLy8gSG93ZXZlciwgdGhlIGRlYnVnZ2VyIHNob3VsZCBub3Qg cGF1c2Ugd2hlbiBjYXB0dXJpbmcsIGFuZCB3ZQorICAgICAgICAvLyBzaG91bGQgbm90IHJlcGxh eSBldmVudCBsb29wIGlucHV0cyB3aGlsZSBpbiBhIG5lc3RlZCBydW4gbG9vcC4KKyAgICAgICAg QVNTRVJUKG1fd2l0aGluRXZlbnRMb29wSW5wdXRFeHRlbnQgIT0gd2l0aGluRXZlbnRMb29wSW5w dXRFeHRlbnQgfHwgIShpc0NhcHR1cmluZygpIHx8IGlzUmVwbGF5aW5nKCkpKTsKICAgICAgICAg bV93aXRoaW5FdmVudExvb3BJbnB1dEV4dGVudCA9IHdpdGhpbkV2ZW50TG9vcElucHV0RXh0ZW50 OwogICAgIH0KIAo=
