XBinary: Extended Binary Format Support for Mac OS X - 0 views

  • Extended Binary Format Support
  • © Amit Singh
  • January 2009
  • ...51 more annotations...
  • —With the advent of x86-based Macintosh computers, Universal binaries, originally known as "fat" or multiple-architecture binaries, appeared in Mac OS X.
  • Universal Binaries
  • for one or more architectures
  • along with a header that describes each constituent binary.
  • a wrapper that contains Mach-O binaries
  • a "4-way fat" executable could consist of Mach-O executables for the i386 (32-bit Intel), x86_64 (64-bit Intel), ppc (32-bit PowerPC), and ppc64 (64-bit PowerPC) architectures
  • Mac OS X does not provide any kernel-level or user-level interfaces to extend binary format support.
  • we'll need to write special software
  • new kernel functionality
  • software will involve a kernel extension.
  • extend the kernel
  • and execute them through specified handler programs.
  • Let us call the new software that implements these features XBinary. binfmt_misc Those familiar with the Linux kernel will realize that functionality similar to what's been described here exists in Linux as the binfmt_misc kernel feature. XBinary is conceptually similar
  • XBinary also has some Mac OS X specific features.
  • download and install the XBinary package
  • a command-line tool (xbinary
  • a kernel extension (xbinary.kext)
  • research software at this point
  • choosing the best library from an extended fat library file.
  • for developers, researchers, and power users
  • take XBinary for a spin
  • XBinary: extended binary format support for Mac OS X Copyright (c) 2009 Amit Singh. All Rights Reserved. http://osxbook.com The XBinary software allows you to extend the Mac OS X kernel such that it can recognize arbitrary binary formats and execute them through specified handler programs. (Mac OS X natively supports executing only Mach-O binaries, Universal (fat) binaries, and interpreter scripts.) XBinary consists of a kernel extension (xbinary.kext) and this command-line tool, which lets you control the XBinary facility. This requires superuser privileges, so you should run this tool using sudo(8). The XBinary kext must be loaded for the facility to be available.
  • You can add and manipulate in-kernel entries that enable recognition of binary formats.
  • You can also specify flags that affect how a matched entry is processed. By default, the argument vector IS adjusted and setuid/setgid binaries are NOT allowed.
  • make experimentation involving new binary formats easy
  • Let us look at Java applications
  • then specify this wrapper script as the interpreter
  • and subsequently invoke the Java application launcher.
  • given a Java class file
  • a wrapper script
  • We don't even have to write such scripts
    • Graham Perrin
       
      :-)
  • a Universal binary containing, say, Tiger and Leopard versions
  • simplify code creation and maintenance.
  • Consider a 2-way fat binary containing i386 and x86_64 architectures.
  • operating system versions in addition to processor architectures.
    • Graham Perrin
       
      :-)
  • Now think of an "extended" fat binary mechanism that incorporates
  • our hypothetical extended fat binary contains eight "architectures"
  • the extended fat feature as implemented by XBinary is not a complete implementation
  • These examples assume that you are on an x86 (little-endian) machine.
  • XBinary requires Mac OS X 10.5.x (Leopard).
  • Executive Summary This document discusses XBinary, a new software that lets you add kernel-level support for executing files in arbitrary binary formats on Mac OS X.
  • Extending Executability
  • recognize arbitrary binary formats
  • using the xbinary tool
  • copious "help" output
  • Each entry must have as its name a unique identifier string up to 31 bytes in size. Additionally, a set of other arguments specify to the kernel how to recognize that binary format and which interpreter to invoke to handle it. XBinary can recognize a binary EITHER by matching magic bytes within the first page of the file OR by matching a file extension. OTHER_ARGS must be a valid combination of the following arguments (some are optional).
  • that will determine the startup class name
  • Bonus Feature: Extra Fat Binaries
  • Since XBinary is experimental, why not experiment with such a feature too?
  • XBinary wouldn't be able to help the dynamic linker
  • The XBinary software

Alternatives to Apple Spaces | The Apple Blog - 0 views

  •  
    Almost a year ago Apple gave us Leopard (OS X 10.5), and along with it came virtual desktops for the masses, in the form of Spaces. For many this was an interesting new way to expand their workspace virtually. For the rest of us [power users?] it was a letdown in execution. What was worse, the third party options looked to be dwindling as well. Last November I called for third party developers to bring the competition - let's take a look at the result of that call to arms.

Has Apple Bitten Off More Than It Can Chew? (Wired.com) - 0 views

  •  
    Apple has staked its reputation on tight control of a few carefully designed, faultlessly executed products. Now, as Apple expands its reach from computers into music, video, consumer electronics and phones, it's getting harder and harder for the company to make sure all of its products "just work," as its marketing slogan goes. Its growing army of customers is getting more difficult to satisfy, and they're finding a host of new problems, ranging from tapeless camcorder issues to buggy iPhones.

Creating Automator Actions for Apple Remote Desktop (ARD) - 0 views

  •  
    Apple Remote Desktop (ARD) 3 is the latest release of Apple's desktop management software, enabling administrators to distribute software, manage assets, and remotely administer Mac OS X systems via a network. ARD 3 takes advantage of innovative technologies in Mac OS X Tiger such as Automator. Automator is built on the concept of actions - discrete tasks such as opening a file, cropping an image, or sending a message. With Automator users can string together a series of actions into a single Automator workflow document. Much like a script, a workflow document can be executed, triggering each action and passing any data generated by the action to the next action in the workflow. Using the Automator actions installed with ARD and custom actions you create, you can develop workflows to automate repetitive system administration tasks. For example, workflows can distribute software, create detailed software and hardware reports, and remotely configure systems using ARD.
