2528 Thread_21120628: JavaScriptCore::Marking

Inside Finder.app there is a JavaScriptCore doing your text rendering!

I was so (unpleasantly) surprised by this. I thought M$ tried this also, 10 years ago, and failed horribly.
Well, to ease the worries. It's just part of JS core that has been used, not the full JS implementation.

I've reported a bug to Apple about this issue.

Xcode hangs

Oh, I have had so many crashes and no time to blog about them. Let me get back on those later.
Today starts with a hanging Xcode. This is the trace (without the not-so-interesting parts):

Xcode has been in this state already for half an hour. It is still drawing the search results view as it seems. In the mean time, Xcode's memory profile is increasing slowly (from 800MB to 1.2GB over 30 minutes).

The Cause

Recently, I've added big files to the Xcode project (finaliser .fin files). They are by Xcode considered as text files, and cause the search to be impossibly slow, or hang forever (more than 1 hour for a search operation equals to infinite, if you are busy solving a problem).

The Fix

A quick fix is to mark these files as not-text in the project file.

• Find the big file(s) in your project
• Open the file, and open the Utility tab
• Under "Identity and Type", change "File Type" to (for example) "Resource Archive"
