Bug 213873

Summary:	Web Inspector: Source map locations in minified files are incorrect
Product:	WebKit	Reporter:	evan.exe
Component:	Web Inspector	Assignee:	Nobody <webkit-unassigned>
Status:	RESOLVED DUPLICATE
Severity:	Normal	CC:	inspector-bugzilla-changes, webkit-bug-importer, ysuzuki
Priority:	P2	Keywords:	InRadar
Version:	Safari 13
Hardware:	All
OS:	All

Description evan.exe 2020-07-01 23:48:22 PDT

Repro:

1. Visit https://evanw.github.io/browser-source-map-bugs/#safari
2. Open the browser console

Expected:

Both the unminified and minified stack traces should match. The first stack frame should be "other.ts" on line 2 and the second stack frame should be "entry.ts" on line 6.

Observed:

The unminified stack trace is correct but the minified stack trace is incorrect. In the minified stack trace, both frames are "entry.ts" on line 7.

Apologies if this bug has already been fixed in WebKit Nightly. I can't test it because WebKit Nightly isn't supported on macOS Mojave 10.14.

I believe these locations to be correct because these are the locations reported by Mozilla's source map library: https://github.com/mozilla/source-map. See https://github.com/evanw/browser-source-map-bugs/blob/gh-pages/verify.js for the verification script.
