py: Explicitly set uninitialised struct member to false.

2014-11-03T16:18:51+00:00

Uninitialised struct members get a default value of 0/false, so this is not strictly needed. But it actually decreases code size because when all members are initialised the compiler doesn't need to insert a call to memset to clear everything. In other words, setting 1 extra member to 0 uses less code than calling memset. ROM savings in bytes: 32-bit unix: 100; bare-arm: 44; stmhal: 52.

py: Fix builtin callable so it checks user-defined instances correctly.

2014-11-03T16:09:39+00:00

Addresses issue #953.

py: Fix bug with right-shifting small ints by large amounts.

2014-11-02T00:41:30+00:00

Undefined behavior in C, needs explicit check.

py: Make gc.enable/disable just control auto-GC; alloc is still allowed.

2014-10-31T21:30:46+00:00

gc.enable/disable are now the same as CPython: they just control whether automatic garbage collection is enabled or not. If disabled, you can still allocate heap memory, and initiate a manual collection.

py: Add builtin round function.

Addresses issue #934.

mpz: Fix 64bit msvc build

2014-10-30T23:00:24+00:00

msvc does not treat 1L a 64bit integer hence all occurences of shifting it left or right result in undefined behaviour since the maximum allowed shift count for 32bit ints is 31. Forcing the correct type explicitely, stored in MPZ_LONG_1, solves this.

objstr: Allow to convert any buffer proto object to str.

2014-10-30T22:03:53+00:00

Original motivation is to support converting bytearrays, but easier to just support buffer protocol at all.

py: mp_obj_str_get_str(): Work with bytes too.

2014-10-30T22:00:39+00:00

It should be fair to say that almost in all cases where some API call expects string, it should be also possible to pass byte string. For example, it should be open/delete/rename file with name as bytestring. Note that similar change was done quite a long ago to mp_obj_str_get_data().

py: Allow to override port config file and thus have >1 configs per port.

2014-10-29T23:37:45+00:00

Use it like: make CFLAGS_EXTRA='-DMP_CONFIGFILE=""'

Fix errors after enabling -Wpointer-arith
