Huge datasets are displayed and handled (arrays containing up to 500,000 data points). Issue: When using the debugger and stopping at breakpoint or manually stepping, when you hover over a variable, a popup will show with the value of the variable. Great feature. But, when hovering over one of those huge arrays, a popup will show up too, and even show "Array[<huge total>]" header in it, but the rest of the popup stays empty, the tab or window freezes and two processes peg 2 cores at 100%, each using 1,45GB memory (the processes are 'SafariForWebKitDevelopment Web Content' and 'Safari Web Content'). I can then only close the tab or window, the rest of the tab or window is frozen. Expected behavior: The first few entries in the array should show up in the popover. 969198 1 webkit-bug-importer 2014-01-17 12:11:33 -0800 <rdar://problem/15847944> 1453201 2 bburg 2018-08-23 13:37:28 -0700 *** This bug has been marked as a duplicate of bug 143589 *** 1453203 3 bburg 2018-08-23 13:37:50 -0700 We only fetch the first 100 entries, but this isn't great either.
