This is fixing a regression in iOS 11. Previously, we would use mediaserverd and apps using WebViews could play audio in the background. In iOS11 however, we do the networking by ourselves instead of using mediaserverd, and we need to keep the NetworkProcess alive as well to maintain feature-parity. Despite the bug title, this is not and is not intended to be specific to MobileSafari. 1323715 5 314052 rniwa 2017-06-28 16:14:34 -0700 Comment on attachment 314052 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=314052&action=review > Source/WebKit2/ChangeLog:3 > + [iOS] Allow MobileSafari to play audio in the background Please fix the bug title accordingly since this applies to WKWebView clients other than MobileSafari. 1323720 6 cdumez 2017-06-28 16:22:33 -0700 Committed r218902: <http://trac.webkit.org/changeset/218902> 314052 2017-06-28 12:26:47 -0700 2017-06-28 16:14:34 -0700 Patch bug-173932-20170628122646.patch text/plain 2519 cdumez U3VidmVyc2lvbiBSZXZpc2lvbjogMjE4ODc2CmRpZmYgLS1naXQgYS9Tb3VyY2UvV2ViS2l0Mi9D aGFuZ2VMb2cgYi9Tb3VyY2UvV2ViS2l0Mi9DaGFuZ2VMb2cKaW5kZXggMWRiZjVkYjdlMDZhYzM4 YmFjZmNkNWRlYjliYmM0YWI5MmY4ZjIzNC4uZmQ5MjAzMDlhZmViNjY4OTBlZjk2NzUwMWI1OWVk Zjg1YmJjMjk2MSAxMDA2NDQKLS0tIGEvU291cmNlL1dlYktpdDIvQ2hhbmdlTG9nCisrKyBiL1Nv dXJjZS9XZWJLaXQyL0NoYW5nZUxvZwpAQCAtMSw1ICsxLDE5IEBACiAyMDE3LTA2LTI4ICBDaHJp cyBEdW1leiAgPGNkdW1lekBhcHBsZS5jb20+CiAKKyAgICAgICAgW2lPU10gQWxsb3cgTW9iaWxl U2FmYXJpIHRvIHBsYXkgYXVkaW8gaW4gdGhlIGJhY2tncm91bmQKKyAgICAgICAgaHR0cHM6Ly9i dWdzLndlYmtpdC5vcmcvc2hvd19idWcuY2dpP2lkPTE3MzkzMgorICAgICAgICA8cmRhcjovL3By b2JsZW0vMzI4NTE1NDc+CisKKyAgICAgICAgUmV2aWV3ZWQgYnkgTk9CT0RZIChPT1BTISkuCisK KyAgICAgICAgQWxsb3cgTW9iaWxlU2FmYXJpIHRvIHBsYXkgYXVkaW8gaW4gdGhlIGJhY2tncm91 bmQgYnkgdGFraW5nIGEgcHJvY2VzcyBhc3NlcnRpb24KKyAgICAgICAgd2hlbmV2ZXIgYSBXZWJQ YWdlIGlzIGF1ZGlibGUuCisKKyAgICAgICAgKiBVSVByb2Nlc3MvV2ViUGFnZVByb3h5LmNwcDoK KyAgICAgICAgKFdlYktpdDo6V2ViUGFnZVByb3h5Ojp1cGRhdGVUaHJvdHRsZVN0YXRlKToKKwor MjAxNy0wNi0yOCAgQ2hyaXMgRHVtZXogIDxjZHVtZXpAYXBwbGUuY29tPgorCiAgICAgICAgIEF2 b2lkIGRvdWJsZSB0aHJlYWQgZGlzcGF0Y2ggaW4gV2Vic2l0ZURhdGFTdG9yZTo6ZmV0Y2hEYXRh Rm9yVG9wUHJpdmF0ZWx5Q29udHJvbGxlZERvbWFpbnMoKQogICAgICAgICBodHRwczovL2J1Z3Mu d2Via2l0Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9MTczOTA0CiAKZGlmZiAtLWdpdCBhL1NvdXJjZS9X ZWJLaXQyL1VJUHJvY2Vzcy9XZWJQYWdlUHJveHkuY3BwIGIvU291cmNlL1dlYktpdDIvVUlQcm9j ZXNzL1dlYlBhZ2VQcm94eS5jcHAKaW5kZXggZWMwNjljZGZjMjIxNTJjZjQ4MGQ5MzY3ZmVhYzYy ZWFkNmIzNGE4Ny4uODQ5MWYyNDc2ZGJhMjcyZDQ1YTAzMGNmM2ExODg1MTBmY2MzNjE1OCAxMDA2 NDQKLS0tIGEvU291cmNlL1dlYktpdDIvVUlQcm9jZXNzL1dlYlBhZ2VQcm94eS5jcHAKKysrIGIv U291cmNlL1dlYktpdDIvVUlQcm9jZXNzL1dlYlBhZ2VQcm94eS5jcHAKQEAgLTE1MjgsNyArMTUy OCw4IEBAIHZvaWQgV2ViUGFnZVByb3h5Ojp1cGRhdGVUaHJvdHRsZVN0YXRlKCkKIAogI2lmIFBM QVRGT1JNKElPUykKICAgICBib29sIGlzQ2FwdHVyaW5nTWVkaWEgPSBtX2FjdGl2aXR5U3RhdGUg JiBBY3Rpdml0eVN0YXRlOjpJc0NhcHR1cmluZ01lZGlhOwotICAgIGlmICghaXNWaWV3VmlzaWJs ZSgpICYmICFtX2Fsd2F5c1J1bnNBdEZvcmVncm91bmRQcmlvcml0eSAmJiAhaXNDYXB0dXJpbmdN ZWRpYSkgeworICAgIGJvb2wgaXNBdWRpYmxlID0gbV9hY3Rpdml0eVN0YXRlICYgQWN0aXZpdHlT dGF0ZTo6SXNBdWRpYmxlOworICAgIGlmICghaXNWaWV3VmlzaWJsZSgpICYmICFtX2Fsd2F5c1J1 bnNBdEZvcmVncm91bmRQcmlvcml0eSAmJiAhaXNDYXB0dXJpbmdNZWRpYSAmJiAhaXNBdWRpYmxl KSB7CiAgICAgICAgIGlmIChtX2FjdGl2aXR5VG9rZW4pIHsKICAgICAgICAgICAgIFJFTEVBU0Vf TE9HX0lGX0FMTE9XRUQoUHJvY2Vzc1N1c3BlbnNpb24sICIlcCAtIFVJUHJvY2VzcyBpcyByZWxl YXNpbmcgYSBmb3JlZ3JvdW5kIGFzc2VydGlvbiBiZWNhdXNlIHRoZSB2aWV3IGlzIG5vIGxvbmdl ciB2aXNpYmxlIiwgdGhpcyk7CiAgICAgICAgICAgICBtX2FjdGl2aXR5VG9rZW4gPSBudWxscHRy OwpAQCAtMTUzNiw2ICsxNTM3LDggQEAgdm9pZCBXZWJQYWdlUHJveHk6OnVwZGF0ZVRocm90dGxl U3RhdGUoKQogICAgIH0gZWxzZSBpZiAoIW1fYWN0aXZpdHlUb2tlbikgewogICAgICAgICBpZiAo aXNWaWV3VmlzaWJsZSgpKQogICAgICAgICAgICAgUkVMRUFTRV9MT0dfSUZfQUxMT1dFRChQcm9j ZXNzU3VzcGVuc2lvbiwgIiVwIC0gVUlQcm9jZXNzIGlzIHRha2luZyBhIGZvcmVncm91bmQgYXNz ZXJ0aW9uIGJlY2F1c2UgdGhlIHZpZXcgaXMgdmlzaWJsZSIsIHRoaXMpOworICAgICAgICBlbHNl IGlmIChpc0F1ZGlibGUpCisgICAgICAgICAgICBSRUxFQVNFX0xPR19JRl9BTExPV0VEKFByb2Nl c3NTdXNwZW5zaW9uLCAiJXAgLSBVSVByb2Nlc3MgaXMgdGFraW5nIGEgZm9yZWdyb3VuZCBhc3Nl cnRpb24gYmVjYXVzZSB3ZSBhcmUgcGxheWluZyBhdWRpbyIsIHRoaXMpOwogICAgICAgICBlbHNl IGlmIChpc0NhcHR1cmluZ01lZGlhKQogICAgICAgICAgICAgUkVMRUFTRV9MT0dfSUZfQUxMT1dF RChQcm9jZXNzU3VzcGVuc2lvbiwgIiVwIC0gVUlQcm9jZXNzIGlzIHRha2luZyBhIGZvcmVncm91 bmQgYXNzZXJ0aW9uIGJlY2F1c2UgbWVkaWEgY2FwdHVyZSBpcyBhY3RpdmUiLCB0aGlzKTsKICAg ICAgICAgZWxzZQo=
