Daniel Jalkut on crash logs & atos

December 07, 2007

Great writeup from Daniel Jalkut on examining crash logs with the atos command line tool:

Many developers seem to think that gathering useful crash logs requires shipping a symbol-laden application, but aren’t willing to do so. The fact is, you can have the best of both worlds by shipping a symbol-stripped version of your application, but keeping a symbol-laden version on-hand for the developer’s convenience. What am I getting at? Apple offers a tool called "atos", which makes it relatively easy to map an address from a symbol-stripped application to a name in a symbol-laden version of that same application. As long as the two applications were built with the same sources and using the same build options, the addresses are bound to match up. It’s just the symbols that are "stripped" from the shipping application.
