The GC was paging in more memory to run and so it was unable to finish before the next low memory signal fired. We think with the new style of GC we will not get any value to forcing GC during a low memory signal so we should remove the call. <rdar://problem/11094830> WebProcess appears to get stuck in its GC handler 586866 1 133588 slewis 2012-03-23 17:07:25 -0700 Created attachment 133588 patch 586868 2 133588 ggaren 2012-03-23 17:10:09 -0700 Comment on attachment 133588 patch r=me 589150 3 eric 2012-03-27 12:36:36 -0700 Attachment 133588 was posted by a committer and has review+, assigning to Stephanie Lewis for commit. 589219 4 slewis 2012-03-27 13:29:58 -0700 Committed http://trac.webkit.org/projects/webkit/changeset/111977 133588 2012-03-23 17:07:25 -0700 2012-03-23 17:10:09 -0700 patch 0001-https-bugs.webkit.org-show_bug.cgi-id-81963-WebProce.patch text/plain 2648 slewis RnJvbSBlNjFmZDA0OTlhNzlmMjU4ZWJhYTM2M2JkZDdiNzM4YWU3YjE2ZmFjIE1vbiBTZXAgMTcg MDA6MDA6MDAgMjAwMQpGcm9tOiBTdGVwaGFuaWUgTGV3aXMgPHNsZXdpc0BhcHBsZS5jb20+CkRh dGU6IFRodSwgMjIgTWFyIDIwMTIgMTU6MzU6MDkgLTA3MDAKU3ViamVjdDogW1BBVENIXSBodHRw czovL2J1Z3Mud2Via2l0Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9ODE5NjMgV2ViUHJvY2VzcyBjYW4K IGdldCBzdHVjayBpbiBHQyBkdXJpbmcgbWFueSBsb3cgbWVtb3J5IHNpZ25hbHMuCiA8cmRhcjov L3Byb2JsZW0vMTEwOTQ4MzA+IFdlYlByb2Nlc3MgYXBwZWFycyB0byBnZXQgc3R1Y2sKIGluIGl0 cyBHQyBoYW5kbGVyICg4MTk2MykuIFJlbW92ZSBHQyBjYWxsLgoKUmVtb3ZlIHRoZSBjYWxsIHRv IGdhcmJhZ2UgY29sbGVjdCAgaW4gbG93IG1lbW9yeSBzaWduYWwgaGFuZGxlci4gIERpZCBzb21l IHRlc3Rpbmcgd2l0aCBoaXR0aW5nIHRoZSBsb3cgbWVtb3J5IGhhbmRsZXIKZHVyaW5nIE1lbWJ1 c3RlciBhbmQgd2Ugd291bGQgZ2V0IGJhY2sgYXQgbW9zdCAxMDBrIC0gMjAway4gIFRoYXQgaXNu J3QgZW5vdWdoIHRvIGhlbHAgdGhlIHN5c3RlbSwgYW5kIGluCnRoYXQgc3RhdGUgdGhlIEdDIGNv bGxlY3Rpb24gY2FuIHRha2UgYSBzdWJzdGFudGlhbCBhbW91bnQgb2YgdGltZS4KClJldmlld2Vk IGJ5IE5PQk9EWSAoT09QUyEpLgoKUGVyZm9ybWFuY2UgQ2hhbmdlLCBubyBjaGFuZ2UgaW4gYmVo YXZpb3IuCgoqIHBsYXRmb3JtL21hYy9NZW1vcnlQcmVzc3VyZUhhbmRsZXJNYWMubW06CihXZWJD b3JlOjpNZW1vcnlQcmVzc3VyZUhhbmRsZXI6OnJlbGVhc2VNZW1vcnkpOgotLS0KIFNvdXJjZS9X ZWJDb3JlL0NoYW5nZUxvZyAgICAgICAgICAgICAgICAgICAgICAgICAgIHwgICAxNSArKysrKysr KysrKysrKysKIC4uLi9wbGF0Zm9ybS9tYWMvTWVtb3J5UHJlc3N1cmVIYW5kbGVyTWFjLm1tICAg ICAgIHwgICAgMiAtLQogMiBmaWxlcyBjaGFuZ2VkLCAxNSBpbnNlcnRpb25zKCspLCAyIGRlbGV0 aW9ucygtKQoKZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJDb3JlL0NoYW5nZUxvZyBiL1NvdXJjZS9X ZWJDb3JlL0NoYW5nZUxvZwppbmRleCA1M2M2NDg0Li44NDcxZjU3IDEwMDY0NAotLS0gYS9Tb3Vy Y2UvV2ViQ29yZS9DaGFuZ2VMb2cKKysrIGIvU291cmNlL1dlYkNvcmUvQ2hhbmdlTG9nCkBAIC0x LDMgKzEsMTggQEAKKzIwMTItMDMtMjMgIFN0ZXBoYW5pZSBMZXdpcyAgPHNsZXdpc0BhcHBsZS5j b20+CisKKyAgICAgICAgaHR0cHM6Ly9idWdzLndlYmtpdC5vcmcvc2hvd19idWcuY2dpP2lkPTgx OTYzIFdlYlByb2Nlc3MgY2FuIGdldCBzdHVjayBpbiBHQyBkdXJpbmcgbWFueSBsb3cgbWVtb3J5 IHNpZ25hbHMuCisgICAgICAgIDxyZGFyOi8vcHJvYmxlbS8xMTA5NDgzMD4gV2ViUHJvY2VzcyBh cHBlYXJzIHRvIGdldCBzdHVjayBpbiBpdHMgR0MgaGFuZGxlciAoODE5NjMpLgorICAgICAgICBS ZW1vdmUgdGhlIGNhbGwgdG8gZ2FyYmFnZSBjb2xsZWN0ICBpbiBsb3cgbWVtb3J5IHNpZ25hbCBo YW5kbGVyLiAgRGlkIHNvbWUgdGVzdGluZyB3aXRoIGhpdHRpbmcgdGhlIGxvdyBtZW1vcnkgaGFu ZGxlcgorICAgICAgICBkdXJpbmcgTWVtYnVzdGVyIGFuZCB3ZSB3b3VsZCBnZXQgYmFjayBhdCBt b3N0IDEwMGsgLSAyMDBrLiAgVGhhdCBpc24ndCBlbm91Z2ggdG8gaGVscCB0aGUgc3lzdGVtLCBh bmQgaW4gCisgICAgICAgIHRoYXQgc3RhdGUgdGhlIEdDIGNvbGxlY3Rpb24gY2FuIHRha2UgYSBz dWJzdGFudGlhbCBhbW91bnQgb2YgdGltZS4KKworICAgICAgICBSZXZpZXdlZCBieSBOT0JPRFkg KE9PUFMhKS4KKworICAgICAgICBQZXJmb3JtYW5jZSBDaGFuZ2UsIG5vIGNoYW5nZSBpbiBiZWhh dmlvci4KKworICAgICAgICAqIHBsYXRmb3JtL21hYy9NZW1vcnlQcmVzc3VyZUhhbmRsZXJNYWMu bW06CisgICAgICAgIChXZWJDb3JlOjpNZW1vcnlQcmVzc3VyZUhhbmRsZXI6OnJlbGVhc2VNZW1v cnkpOgorCiAyMDEyLTAzLTIzICBBZGFtIEtsZWluICA8YWRhbWtAY2hyb21pdW0ub3JnPgogCiAg ICAgICAgIE1hdGNoIERPTTQgc3BlYyB3aXRoIHJlc3BlY3QgdG8gRG9jdW1lbnRGcmFnbWVudCBp bnNlcnRpb24KZGlmZiAtLWdpdCBhL1NvdXJjZS9XZWJDb3JlL3BsYXRmb3JtL21hYy9NZW1vcnlQ cmVzc3VyZUhhbmRsZXJNYWMubW0gYi9Tb3VyY2UvV2ViQ29yZS9wbGF0Zm9ybS9tYWMvTWVtb3J5 UHJlc3N1cmVIYW5kbGVyTWFjLm1tCmluZGV4IDBlNDEwZDkuLjE3MjdiYWMgMTAwNjQ0Ci0tLSBh L1NvdXJjZS9XZWJDb3JlL3BsYXRmb3JtL21hYy9NZW1vcnlQcmVzc3VyZUhhbmRsZXJNYWMubW0K KysrIGIvU291cmNlL1dlYkNvcmUvcGxhdGZvcm0vbWFjL01lbW9yeVByZXNzdXJlSGFuZGxlck1h Yy5tbQpAQCAtMTM1LDggKzEzNSw2IEBAIHZvaWQgTWVtb3J5UHJlc3N1cmVIYW5kbGVyOjpyZWxl YXNlTWVtb3J5KGJvb2wgY3JpdGljYWwpCiAKICAgICBtZW1vcnlDYWNoZSgpLT5wcnVuZVRvUGVy Y2VudGFnZShjcml0aWNhbCA/IDAgOiAwLjVmKTsKIAotICAgIGdjQ29udHJvbGxlcigpLmdhcmJh Z2VDb2xsZWN0Tm93KCk7Ci0KICAgICBXVEY6OnJlbGVhc2VGYXN0TWFsbG9jRnJlZU1lbW9yeSgp OwogfQogI2VuZGlmCi0tIAoxLjcuNS40Cgo=
