SSR transform sets `map.sources` paths incorrectly #18144

AriPerkkio · 2024-09-19T08:24:22Z

Describe the bug

When Vite SSR transforms file that has source map with multiple sources, it sets the map.sources paths incorrectly. This causes issues in Vitest: vitest-dev/vitest#6526

With source map like:

{
  sources: [
    "../node_modules/.pnpm/base32-decode@1.0.0/node_modules/base32-decode/index.js",
    "pkg-a-entrypoint.js",
  ]
}

... Vite incorrectly prepends the both source as following.

{
  [
    '../node_modules/.pnpm/base32-decode@1.0.0/node_modules/node_modules/.pnpm/base32-decode@1.0.0/node_modules/base32-decode/index.js',
    '../node_modules/.pnpm/base32-decode@1.0.0/node_modules/base32-decode/pkg-a-entrypoint.js'
  ]
}

There is no ../node_modules/.pnpm/base32-decode@1.0.0/node_modules/node_modules/ or ../node_modules/.pnpm/base32-decode@1.0.0/node_modules/base32-decode/pkg-a-entrypoint.js on filesystem.

The bug happens here:

vite/packages/vite/src/node/utils.ts

Lines 864 to 874 in b529b6f

    
           map = remapping(sourcemapList[0], function loader(sourcefile) { 
        
             const mapForSources = sourcemapList 
        
               .slice(mapIndex) 
        
               .find((s) => s.sources.includes(sourcefile)) 
        
             if (mapForSources) { 
        
               mapIndex++ 
        
               return mapForSources 
        
             } 
        
             return null 
        
           })
