1364347 - JSON parse error when saving profile

Status: RESOLVED DUPLICATE of bug 1364442

(Core :: Gecko Profiler, defect)

Description

[Lars T Hansen [:lth]]

Attachment: gecko-profiler-json-bug.tar

I'll attach a tar with the TC (it originates in bug 1353292).  It untars as a directory called 'Test 1' (sorry).

This is in this morning's mozilla-inbound code, changeset:   357986:27fb70fdc744, built for Release.

This is with a freshly installed Gecko Profiler add-on.

I enable the profiler, load the TC's HTML from file, then wait for the TC to signal "Done".  You want a Release build for this.  I then click on "Capture profile" in the profile extension's window.

The output in the window is this:

  Couldn't retrieve the profile from the gecko profiler addon.
  Error was "SyntaxError: JSON.parse: expected double-quoted property name at
  line 2 column 16 of the JSON data". The full stack has been written to the
  Web Console.

The output in the console is this:

SyntaxError: JSON.parse: expected double-quoted property name at line 2 column 16 of the JSON data

Ditto with a freshly downloaded Nightly build and a clean profile and a freshly installed profiler and any random web page.  (I used https://axis-of-eval.org which is plain html, no JS, plugins, images.)

Appears this may be a dup of 1364442.

Comment 3

[Markus Stange [:mstange]]

Duping forward because bug 1364442 has a bit more concrete information about where the bug is.
