Hi folks, Are you aware of this issue with web Inspector which we see on WinCairo?
Thanks, Rupali From: [email protected] [mailto:[email protected]] On Behalf Of Sharma, Rupali Sent: Wednesday, August 26, 2015 11:16 AM To: [email protected] Subject: [webkit-help] Issue with Web Inspector debugger breakpoint handling (on Wincairo) Hello, We are seeing an issue with the Web Inspector debugger on latest WinCairo [ using Webkit r188436]. In the wincairo webinpector, whenever a breakpoint is set and then web page reload on a javascript source, the view goes on into some indefinite waiting and never shows up, until we press continue-script-execution or another page-refresh. Here are the simple steps to reproduce it, 1. Launch WinCairo and go to google.com 2. Open Web inspector and open the script source of any .js script 3. Set a breakpoint anywhere 4. Reload the web page What we see is the spinner spinning and never the script source. However, if one presses continue-script-execution from the debugger controls, we get the view back. Some points of debugging we did at our end, (i) We did some digging around the breakpoint setting, and do see the flow correctly being going to handlepause() of the ScriptDebugServer. Though I see the vmEntryGlobalObject is not updated with any value or callframe. I did not see any abnormality in the listener dispatching callback, with the correct pause-reason to pass i.e. Breakpoint. However, I am not sure if its sending the right pause-data to the frontend. (ii)It gets stuck in the infinite eventloop which does look fine to me, as long as it is paused. (iii)Another observation I see is, the message "TimelineRecordingStopped" being sent to the frontend. I believe, this is something newly added and not sure, if at all it'll effect the debugger scriptsource in any way. [reference : doDispatchMessageOnFrontendPage] (iv)Coming onto the Web inspector UI side of story, I did see one bug, that even though the method in DebuggerManager.js "debuggerDidPause" got the right pause-reason from the webkit, its not able to pass on correctly due to an apparent bug in _pauseReasonFromPayload: function(payload) Here, the input payload does not match any of the DebuggerAgent.PausedReason and hence falls to the error of unknown reason. The correct string to match would be "Breakpoint". However, correcting the flow still doesn't give us any favorable behavior. Though, I believe it's good to know. Would you have a better insight as to what exactly is blocking the script source to display in the paused-state of web inspector debugger? The output log looks like: EAWebKit:Event kLETResourceResponseReceived : The server has responded to a resource request URL - http://www.google.com/ with status = 200 EAWebKit:Event kLETLoadCompletedWithoutErrors : The load is completed without errors Total Page Loaded : 1.139 Total Page Lib Tick Update : 0.604 Slowest:: 0.521 Total Page View Tick Update : 0.000 Slowest:: 0.000 Total Page Network Tick Update : 0.000 Total Jobs Loop : 0.503 Slowest:: 0.489 Total Page Script : 0.000 Slowest:: 0.000 Font Glyph Draw : 0.000 Bitmap Image Draw : 0.000 Bitmap Image Decoder : 0.000 Image Compression : 0.000 Font/Image Raster Draw : 0.000 TH Connect : 0.000 TH Transfer : 0.000 TH Disconnect : 0.000 TH Size : 0 TH Files : 0 Cached Connect : 0.000 Cached Transfer : 0.000 Cached Disconnect : 0.000 Cached Size : 0 Cached files : 0 Java Script Parse : 0.000 Java Script Execute : 0.000 CSS Sheet Parse : 0.000 Font Loading Time : 0.000 Page user1 : 0.000 Page user2 : 0.000 Page user3 : 0.000 EAWebKit:Event kLETResourceResponseReceived : The server has responded to a resource request URL - http://www.google.com/xjs/_/js/k=xjs.hp.en_US.dipijOltWAk.O/m=sb_he,d/rt=j/d=1/t=zcms/rs=ACT90oGH2j95ix8dWTU-Ejrgyf_E0GhQSQ with status = 200 2015/08/26-10:51:01.462 protoupnp: multicasting discovery request EAWebKit: JS - file:///C:/EAOS/EAOS/EAWebKit/SB/InternalTeam/w-179714/EAWebKitDemoUTFWin/dev/data/WebInspectorUI/UserInterface/Controllers/DebuggerManager.js<file:///C:\EAOS\EAOS\EAWebKit\SB\InternalTeam\w-179714\EAWebKitDemoUTFWin\dev\data\WebInspectorUI\UserInterface\Controllers\DebuggerManager.js> Line-464 Column-20 Message: DebuggerDidPause called ----> got some data and reason EAWebKit: JS - file:///C:/EAOS/EAOS/EAWebKit/SB/InternalTeam/w-179714/EAWebKitDemoUTFWin/dev/data/WebInspectorUI/UserInterface/Controllers/DebuggerManager.js<file:///C:\EAOS\EAOS\EAWebKit\SB\InternalTeam\w-179714\EAWebKitDemoUTFWin\dev\data\WebInspectorUI\UserInterface\Controllers\DebuggerManager.js> Line-465 Column-20 Message: pause reason isBreakpoint EAWebKit: JS - file:///C:/EAOS/EAOS/EAWebKit/SB/InternalTeam/w-179714/EAWebKitDemoUTFWin/dev/data/WebInspectorUI/UserInterface/Controllers/DebuggerManager.js<file:///C:\EAOS\EAOS\EAWebKit\SB\InternalTeam\w-179714\EAWebKitDemoUTFWin\dev\data\WebInspectorUI\UserInterface\Controllers\DebuggerManager.js> Line-466 Column-20 Message: pause data is[object Object] EAWebKit: JS - file:///C:/EAOS/EAOS/EAWebKit/SB/InternalTeam/w-179714/EAWebKitDemoUTFWin/dev/data/WebInspectorUI/UserInterface/Controllers/DebuggerManager.js<file:///C:\EAOS\EAOS\EAWebKit\SB\InternalTeam\w-179714\EAWebKitDemoUTFWin\dev\data\WebInspectorUI\UserInterface\Controllers\DebuggerManager.js> Line-628 Column-20 Message: 1. payload to _pauseReasonFrompaylod is Breakpoint EAWebKit: JS - file:///C:/EAOS/EAOS/EAWebKit/SB/InternalTeam/w-179714/EAWebKitDemoUTFWin/dev/data/WebInspectorUI/UserInterface/Controllers/DebuggerManager.js<file:///C:\EAOS\EAOS\EAWebKit\SB\InternalTeam\w-179714\EAWebKitDemoUTFWin\dev\data\WebInspectorUI\UserInterface\Controllers\DebuggerManager.js> Line-635 Column-23 Message: >>> Payload is Breakpoint?
