Bug 114929 – Web Inspector: ConsoleMessage should include line and column number where possible

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

[Joseph Pecoraro]

Currently ConsoleMessage only includes line number information. However, if the original source code is reformatted in the frontend (e.g. pretty printed), then having just the original line number is not enough information to know where the original source code moved too. To know that the frontend would need to know both the line and column number in the original source.

ConsoleMessages should have a column number.

[PATCH] Add column number alongside line number

This patch:

  - adds column number (almost) everywhere where line number is available. (Follow up will come for exceptions)
  - exposes column to ChromeClient alongside line number
  - adds column to ConsoleMessages in the Inspector Protocol.
  - provides a column for console.* function calls (log, error, etc.)

Lets see how the bot does on other ports.

This basically looks fine to me, but i'm going to r- it anyway because i'm annoying.  We now _always_ generate a stack trace when we throw an exception, we may as well just show it in the console (either in line, or via a drop down, i'm easy with either, but i also wouldn't want me designing UI for anything so I'm going to leave the decision with you)

>>> Source/WebKit/efl/WebCoreSupport/ChromeClientEfl.cpp:277

You're changing this line, you may as well fix the style foible

ditto

[Timothy Hatcher]

We do show the stack trace and have for a while. It is the disclosure triangle at the beginning of the error message, if it is available. Not the best or most discoverable UI, but we might change it sometime soon to something better.

[Timothy Hatcher]

Note: we only capture stack traces if the Inspector is open. And I think it is limited to 5 call frames. Those rules were established by Google, and can be subject to change.

[Timothy Hatcher]

So Joe needed to do it this way to allow columns to work when the Inspector isn't open.

[Timothy Hatcher]

With that said, I still don't see the stack trace showing up in the Inspector for exceptions. Maybe we are only getting it for normal console messages?

With Oliver's improvements can now get this information for exceptions. However, I haven't modified the exception path with this patch. That will come in the next set of patches.

I wanted to try and take smaller steps after getting this large step out of the way, but let me take another look at making things more consistent now if needed.

Yep, fixes "exceptions" will be in a follow up bug later (sometime this week). This starts with just the console API messages. I'll add a test to this that console API messages all have stacktraces if it makes sense.

The different layout-test-results was just me forgetting to git add the new expected results to the patch attached. I fixed it locally. I'll land this tomorrow when I can watch the bots.

  Seems fine, but isn't happening locally for me. Need to investigate.

  No idea what would be going on here.
