profiler-cli-v0.8.0

Highlights

• Add the ability to apply source maps from the CLI by @canova in #6229
  • A new sourcemap command group: profiler-cli sourcemap sources lists the sources that carry a source map URL, and profiler-cli sourcemap apply bundle.js.map re-symbolicates the affected stacks in place, auto-matching a source (or pointing at one explicitly with --to src-N when the match is ambiguous). Maps that carry sourcesContent also make the original source available to profiler-cli function annotate f-N, with per-line sample counts.

What's Changed

• Handle the cli daemon startup failures more gracefully with better errors by @canova in #6241
• Handle Text and Log marker payloads with their marker schema by @canova in #6247
• Bump the Gecko profile version to make sure that the Text and Log marker changes are picked up in the frontends by @canova in #6252
• Only call getRawFrameTableBuilderWithExistingContents once per symbolication batch. by @mstange in #6233
• Bump profiler-cli version to 0.8.0 by @canova in #6254
