Bug 79130 – Web Inspector: replace RawSourceCode with a set of global mappings.

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Pavel Podivilov]

Single source file could be referenced from a bunch of compiler source mappings that came from scripts with different urls (see bug 79122).
RawSourceCode doesn't support this scenario. We need a more generic interface that maps VM scripts to UISourceCodes and back, e.g.:

SourceMapping {
    uiLocation rawLocationToUILocation(scriptId, lineNumber, columnNumber)
    rawLocation uiLocationToRawLocation(uiSourceCode, lineNumber, columnNumber)
    Array<UISourceCode> uiSourceCodeList()
    [event] UISourceCodeListChanged(removed, added)
    addScript(script)
}

As a bonus, resources-based mapping and compiler mapping could be cleanly separated.
As an another bonus, we can easily implement identical mapping that could be used for a "sanity" debugging mode. Identical mapping doesn't bind scripts to resources and displays VM scripts "as is".

This patch moves RawSourceCode towards SourceMapping interface defined in previous comment.
