Lupa change log

0.20 (2011-05-22)

  • fix "deallocating None" crash while iterating over Lua tables in Python code
  • support for filtering attribute access to Python objects for Lua code
  • fix: setting source encoding for Lua code was broken

0.19 (2011-03-06)

  • fix serious resource leak when creating multiple LuaRuntime instances
  • portability fix for binary module importing

0.18 (2010-11-06)

  • fix iteration by returning Py_None object for None instead of nil, which would terminate the iteration
  • when converting Python values to Lua, represent None as a Py_None object in places where nil has a special meaning, but leave it as nil where it doesn't hurt
  • support for counter start value in python.enumerate()
  • native implementation for python.enumerate() that is several times faster
  • much faster Lua iteration over Python objects

0.17 (2010-11-05)

  • new helper function python.enumerate() in Lua that returns a Lua iterator for a Python object and adds the 0-based index to each item.
  • new helper function python.iterex() in Lua that returns a Lua iterator for a Python object and unpacks any tuples that the iterator yields.
  • new helper function python.iter() in Lua that returns a Lua iterator for a Python object.
  • reestablished the python.as_function() helper function for Lua code as it can be needed in cases where Lua cannot determine how to run a Python function.

0.16 (2010-09-03)

  • dropped python.as_function() helper function for Lua as all Python objects are callable from Lua now (potentially raising a TypeError at call time if they are not callable)
  • fix regression in 0.13 and later where ordinary Lua functions failed to print due to an accidentally used meta table
  • fix crash when calling str() on wrapped Lua objects without metatable

0.15 (2010-09-02)

  • support for loading binary Lua modules on systems that support it

0.14 (2010-08-31)

  • relicensed to the MIT license used by LuaJIT2 to simplify licensing considerations

0.13.1 (2010-08-30)

  • fix Cython generated C file using Cython 0.13

0.13 (2010-08-29)

  • fixed undefined behaviour on str(lua_object) when the object's __tostring() meta method fails
  • removed redundant "error:" prefix from LuaError messages
  • access to Python's python.builtins from Lua code
  • more generic wrapping rules for Python objects based on supported protocols (callable, getitem, getattr)
  • new helper functions as_attrgetter() and as_itemgetter() to specify the Python object protocol used by Lua indexing when wrapping Python objects in Python code
  • new helper functions python.as_attrgetter(), python.as_itemgetter() and python.as_function() to specify the Python object protocol used by Lua indexing of Python objects in Lua code
  • item and attribute access for Python objects from Lua code

0.12 (2010-08-16)

  • fix Lua stack leak during table iteration
  • fix lost Lua object reference after iteration

0.11 (2010-08-07)

  • error reporting on Lua syntax errors failed to clean up the stack so that errors could leak into the next Lua run
  • Lua error messages were not properly decoded

0.10 (2010-07-27)

0.9 (2010-07-23)

  • fixed Python special double-underscore method access on LuaObject instances
  • Lua coroutine support through dedicated wrapper classes, including Python iteration support. In Python space, Lua coroutines behave exactly like Python generators.

0.8 (2010-07-21)

  • support for returning multiple values from Lua evaluation
  • repr() support for Lua objects
  • LuaRuntime.table() method for creating Lua tables from Python space
  • encoding fix for str(LuaObject)

0.7 (2010-07-18)

  • LuaRuntime.require() and LuaRuntime.globals() methods
  • renamed LuaRuntime.run() to LuaRuntime.execute()
  • support for len(), setattr() and subscripting of Lua objects
  • provide all built-in Lua libraries in LuaRuntime, including support for library loading
  • fixed a thread locking issue
  • fix passing Lua objects back into the runtime from Python space

0.6 (2010-07-18)

  • Python iteration support for Lua objects (e.g. tables)
  • threading fixes
  • fix compile warnings

0.5 (2010-07-14)

  • explicit encoding options per LuaRuntime instance to decode/encode strings and Lua code

0.4 (2010-07-14)

  • attribute read access on Lua objects, e.g. to read Lua table values from Python
  • str() on Lua objects
  • include .hg repository in source downloads
  • added missing files to source distribution

0.3 (2010-07-13)

  • fix several threading issues
  • safely free the GIL when calling into Lua

0.2 (2010-07-13)

  • propagate Python exceptions through Lua calls

0.1 (2010-07-12)

  • first public release
