| 11 | |
| 12 | TO DO |
| 13 | ----- |
| 14 | |
| 15 | - See PEP 3000. |
| 16 | |
| 17 | - Test merging certain changes from the 2.5 HEAD code. |
| 18 | |
| 19 | - Weed really old/weird stuff from the library. |
| 20 | |
| 21 | - Unify range() and xrange(). |
| 22 | |
| 23 | - Revamp the dict API: keys(), values(), items() return iterators, etc. |
| 24 | |
| 25 | - Add the bytes type. |
| 26 | |
| 27 | - Rework the standard I/O library to use bytes for binary files. |
| 28 | |
| 29 | - Make strings all Unicode. |
| 30 | |
| 31 | - Get rid of classic class implementation. |
| 32 | |
| 33 | - Get rid of various compatibility-related flags (e.g. division flags). |
| 34 | |
| 35 | Core and Builtins |
| 36 | ----------------- |
| 37 | |
| 38 | - __coerce__ has been removed. |
| 39 | |
| 40 | - Classic classes are a thing of the past. All classes are new style. |
| 41 | |
| 42 | - Exceptions *must* derive from BaseException. |
| 43 | |
| 44 | - Integer division always returns a float. The -Q option is no more. |
| 45 | All the following are gone: |
| 46 | * PyNumber_Divide and PyNumber_InPlaceDivide |
| 47 | * __div__, __rdiv__, and __idiv__ |
| 48 | * nb_divide, nb_inplace_divide |
| 49 | * operator.div, operator.idiv, operator.__div__, operator.__idiv__ |
| 50 | (Only __truediv__ and __floordiv__ remain, not sure how to handle them |
| 51 | if we want to re-use __div__ and friends. If we do, it will make |
| 52 | it harder to write code for both 2.x and 3.x.) |
| 53 | |
| 54 | - 'as' and 'with' are keywords. |
| 55 | |
| 56 | - Absolute import is the default behavior for 'import foo' etc. |
| 57 | |
| 58 | - Removed these Python builtins: |
| 59 | apply(), coerce(), input(), raw_input() |
| 60 | |
| 61 | - Removed these Python slots: |
| 62 | __coerce__, __div__, __idiv__, __rdiv__ |
| 63 | |
| 64 | - Removed these attributes from Python modules: |
| 65 | * operator module: div, idiv, __div__, __idiv__ |
| 66 | |
| 67 | *** PyNumber_CoerceEx() and nb_coerce still need to be removed. |
| 68 | |
| 69 | - Removed these C APIs: |
| 70 | PyNumber_Coerce(), |
| 71 | |
| 72 | - Removed these C slots/fields: |
| 73 | nb_divide, nb_inplace_divide |
| 74 | |
| 75 | - Removed these macros: |
| 76 | staticforward, statichere, PyArg_GetInt, PyArg_NoArgs |
| 77 | |
| 78 | - Removed these typedefs: |
| 79 | intargfunc, intintargfunc, intobjargproc, intintobjargproc, |
| 80 | getreadbufferproc, getwritebufferproc, getsegcountproc, getcharbufferproc |
| 81 | |
| 82 | - Removed these opcodes: |
| 83 | BINARY_DIVIDE, INPLACE_DIVIDE |
| 84 | |
