Bug 151066 – Web Inspector: Global Breakpoints should always be visible

• Component: Web Inspector
• Status: RESOLVED FIXED

[Matt Baker]

* SUMMARY
Global Breakpoints should always be visible. There are only two global breakpoints, so there isn't much utility in making them filterable.

The current behavior is also inconsistent and confusing. Some examples:

1) Filter text "Global" results in an empty global breakpoints folder in trunk. In Safari 9.0 the child tree elements are also shown.
2) Filter text "All Exceptions" results in nothing.
3) Enabling "Show resources with issues" hides Global Breakpoints.
4) Enabling "Show resources with breakpoints" shows Global Breakpoints.

This does not sound like a function that acts on tree elements. suppressFilteringOnTreeElements?

I think Joe has wanted to get away from this pattern. Just assert.

It seems odd to check this here, since this code hides the empty placeholder, which would never be used if there is even a single tree element with the SuppressFiltering symbol. I think the hidden check is sufficient here.

SuppressFilteringSymbol?

+1! I think we should assert more, and massage inputs less.

This ensures a visible element with the SuppressFilteringSymbol doesn't prevent the placeholder from being shown. In the case of DebuggerSidebarPanel, if all breakpoint elements are hidden by filters, the "No Filter Results" message should be displayed, even though global breakpoints are still visible.

[Image] Elements with SuppressFilteringSymbol

Placeholder message appears when all filterable elements (those with SuppressFilteringSymbol equal to undefined or false) are hidden

Okay, makes sense. This will change once sections are added.
