Description
When debugging in RHEL8 with qt debuginfo packages installed, Local&Expressions Windows was too slow.
I opened debugger log and log time stramps, and found:
"python theDumper.fetchVariables" would take about 2 seconds and each
QtClass would take 700ms like attachments.
When I remove qt debuginfo packages from system, everything is back to normal.
When I used Qt 5.9.8 in RHEL 7 with debuginfo, everything was perfect. Each QtClass only cost
less then 10ms, and full debugging step cost less then 100ms.
&"python theDumper.fetchVariables({\"autoderef\":1,\"context\":\"\",\"displaystringlimit\":\"100\",\"dyntype\":1,\"expanded\":[\"inspect\",\"watch\",\"local\",\"return\"],\"fancy\":1,\"formats\":{},\"nativemixed\":0,\"partialvar\":\"\",\"passexceptions\":0,\"qobjectnames\":1,\"resultvarname\":\"\",\"stringcutoff\":\"10000\",\"timestamps\":1,\"token\":257,\"typeformats\":{},\"watchers\":[]})\n" >~"result={token=\"0\",data=[{iname=\"local.this\",name=\"this\",origaddr=\"0x7fffffffe5b8\",address=\"0x78ffd0\",address=\"0x78ffd0\",numchild=\"1\",time=\"0.00016307830810546875\",type=\"Ui_MainWindow\",value=\"\",},{iname=\"local.MainWindow\",name=\"MainWindow\",origaddr=\"0x7fffffffe5b0\",address=\"0x7fffffffe680\",address=\"0x7fffffffe680\",numchild=\"1\",time=\"0.6441819667816162\",type=\"QMainWindow\",value=\"\",},],typeinfo=[],partial=\"0\",counts={},timings=[]}\n" t06:03:26.067 [1689ms] >257^done t06:03:26.067 tResponse time: python theDumper.fetchVariables({"autoderef":1,"context":"","displaystringlimit":"100","dyntype":1,"expanded":["inspect","watch","local","return"],"fancy":1,"formats":{},"nativemixed":0,"partialvar":"","passexceptions":0,"qobjectnames":1,"resultvarname":"","stringcutoff":"10000","timestamps":1,"token":257,"typeformats":{},"watchers":[]}): 1.695 s t06:03:26.067 <Rebuild Watchmodel 46 @ 06:03:26.067 >
