Release history

macholib 1.7

• Added support for ARM64, LC_ENCRYPTION_INFO_64 and LC_LINKER_OPTION

  Patch by Matthias Ringwald.

• Load commands now have a “describe” method that returns more information about the command.

  Patch by David Dorsey.

• The MAGIC value in the header was always represented in the native byte order, instead of as the value read from the binary.

  Patch by David Dorsey.

• Added various new constants to “macholib.mach_o”.

  Patch by David Dorsey.

macholib 1.6.1

• ?

macholib 1.6

• Add support for '@loader_path‘ link command in macholib.dyld:

  • Added function macholib.dyld.dyld_loader_search
  • This function is used by macholib.dyld.dyld_find, and that function now has an new (optional) argument with the path to the loader.

• Also add support for '@loader_path‘ to macholib.MachoGraph, using the newly added '@loader_path‘ support in the dyld module.

  Due to this suppport the macho_standalone tool can now rewrite binaries that contain an '@loader_path‘ load command.

macholib 1.5.2

• Issue #93: Show the name of the affected file in the exception message for Mach-O headers that are too large to relocate.

macholib 1.5.1

• There were no ‘classifiers’ in the package metadata due to a bug in setup.py.

macholib 1.5

macholib 1.5 is a minor feature release

• No longer use 2to3 to provide Python 3 support

  As a side-effect of this macholib no longer supports Python 2.5 and earlier.

• Adds suppport for some new macho load commands

• Fix for py3k problem in macho_standalone.py

  Patch by Guanqun Lu.

• Fix for some issues in macho_dump.py

  Patch by Nam Nguyen

• Issue #10: Fix for LC_DATA_IN_CODE linker commands, without this fix py2app cannot build application bundles when the source binaries have been compiled with Xcode 4.5.

• Issue #6: Fix for LC_ENCRYPTION_INFO linker commands

• Use the mach header information to print the cpu type of a binary, instead of trying to deduce that from pointer width and endianness.

  Changed the code because of issue #6, in which a user tries to dump a iOS binary which results in bogus output in the previous releases.

• The mapping macholib.macho_dump.ARCH_MAP is undocumented and no longer used by macholib itself. It will be removed in the next release.

• The command-line tools macho_find, macho_dump and macho_standalone are deprecated. Use “python -mmacholib” instead. That is:

  $ python -mmacholib dump /usr/bin/grep
  
  $ python -mmacholib find ~
  
  $ python -mmacholib standalone myapp.app
  

  This makes it clearer which version of the tools are used.

macholib 1.4.3

macholib 1.4.3 is a minor feature release

• Added strings for ‘x86_64’ and ‘ppc64’ to macholib.mach_o.CPU_TYPE_NAMES.

• macho_find and macho_dump were broken in the 1.4.2 release

• added ‘macholib.util.NOT_SYSTEM_FILES’, a list of files that aren’t system path’s even though they are located in system locations.

  Needed to work around a bug in PySide (see issue #32 in the py2app tracker)

macholib 1.4.2

macholib 1.4.2 is a minor bugfix release

• The support for new load commands that was added in 1.4.1 contained a typo that caused problems on OSX 10.7 (Lion).

macholib 1.4.1

macholib 1.4.1 is a minor feature release

Features:

• Add support for a number of new MachO load commands that were added during the lifetime of OSX 10.6: LC_LOAD_UPWARD_DYLIB, LC_VERSION_MIN_MACOSX, LC_VERSION_MIN_IPHONEOS and LC_FUNCTION_STARTS.

macholib 1.4

macholib 1.4 is a feature release

Features:

• Documentation is now generated using sphinx and can be viewed at <http://packages.python.org/macholib>.

• The repository has moved to bitbucket

• There now is a testsuite

• Private functionality inside modules was renamed to a name starting with an underscore.

  Note

  if this change affects your code you are relying on undefined implementation features, please stop using private functions.

• The basic packable types in macholib.ptypes were renamed to better represent the corresponding C type. The table below lists the old an new names (the old names are still available, but are deprecated and will be removed in a future release).

  Old name	New name
  p_byte	p_int8
  p_ubyte	p_uint8
  p_short	p_int16
  p_ushort	p_uint16
  p_int	p_int32
  p_uint	p_uint32
  p_long	p_int32
  p_ulong	p_uint32
  p_longlong	p_int64
  p_ulonglong	p_uint64

  Macholib.ptypes.p_ptr is no longer present as it had an unclear definition and isn’t actually used in the codebase.

Bug fixes:

• The semantics of dyld.dyld_default_search were changed a bit, it now first searches the framework path (if appropriate) and then the linker path, irrespective of the value of the DYLD_FALLBACK* environment variables.

  Previous versions would change the search order when those variables was set, which is odd and doesn’t correspond with the documented behaviour of the system dyld.

• It is once again possible to install using python2.5

• The source distribution includes all files, this was broken due to the switch to mercurial (which confused setuptools)

macholib 1.3

macholib 1.3 is a feature release.

Features:

• Experimental Python 3.x support

  This version contains lightly tested support for Python 3.

macholib 1.2.2

macholib 1.2.2 is a bugfix release.

Bug fixes:

• Macholib should work better with 64-bit code (patch by Marc-Antoine Parent)
