Re: query for system framework symbols

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com -- Terry and it dumped a whole bunch of symbols. As far as atos, goes, it knows about both dwarf and stabs. -- Terry _______________________________________________ Do not post admin requests to the list. They will be ignored. Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… You asked this before. The answer is the same as before. CrashReporter runs atos. Not all symbols are linked into the binary file until the process is running. This is why atos supports the -p option. This is also why CrashReporter runs as a result of intercepting the exception on the task exception port for the process, and pulling the information out of the process address space before it exits. Otherwise it wouldn't be able to get bundle or other information for things that were loaded after it got to _main in your executable program. It also would not recognize local symbols (which show up as 't' instead of 'T' in the output of the "nm" command. Things like Adobe Photoshop which have their own crash reporting facilities do so by taking over the task exception port, and basically reimplementing CrashReporter from scratch, so that they can deal with crashes in third party plugins in their proprietary plugin format, which they wouldn't be able to do otherwise using the system CrashReporter. It would probably be a good idea if you were to specify what you are trying to do, instead of fishing for information about OS internals which are typically adequately covered by the documentation on <http://developer.apple.com/ >; for example, pretty much everything you could want to know about CrashReporter is covered in things like TechNote 2123.

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… dtrace uses fork/exec or posix_spawn (I didn't check which one), while a typical launch (Dock, Finder, open) uses LaunchServices. I'd recommend reworking your script to watch the exec-success of firefox-bin and use a static probe (no need for $target then) to mark the end time. Then you can use a more normal launch method, for example open .../Minefiled.app . I'll fix my scripts. I already have a static probe, e.g. mozilla:::main-entry. I was mistakenly using it with $target. - Using a SSD to measure cold launch is not representative of a typical user. A cold launch using a SSD is much closer to a warm launch using a good old mechanical hard drive. Optimizing this scenario will not necessarily improve the experience of your users. I don't think switching to a slower drive is an option for me. Well, it's an option but I hate to entertain it! I think I'll just try to have the times I get, for example, with the hope that they will be halved for other users as well. What about my "dynamic linking time doesn't matter" thesis? Should I chalk 9 seconds to DTrace overhead? This email sent to site_archiver(a)lists.apple.com
