3c658a4e75 py: Fix bug where GC collected native/viper/asm function data. 
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

25fc41dd31 unix, modtermios: Make it properly configurable; fix spelling mistake. 2014-08-24 13:19:22 +01:00

4f9ebade60 modtermios: Add "termios" unix module, subset of CPython's. 
Also provides setraw() function from "tty" module (which in CPython is
implemented in Python). The idea here is that 95% of "termios" module usage
is to set raw mode to allow access to normal serial devices. Then, instead
of exporting gazillion termios symbols, it's better to implement it in C,
and export minimal number of symbols (mostly baud rates and drain values).

72b115cbaa extmod, zlibd: Make some simple ROM and RAM savings. 
ROM down by 320 bytes on stmhal.  RAM down by 5.5k for a decompression
object.

26a0d4f4f1 py: Change hash and len members of str from 16 bit to full word. 
This allows to make strings longer than 64k.  It doesn't use any more
RAM with current GC because a str object still fits in a GC block.

d5e7f6e37e py: Speed up GC allocation. 
This simple patch gives a very significant speed up for memory allocation
with the GC.

Eg, on PYBv1.0:
tests/basics/dict_del.py: 3.55 seconds -> 1.19 seconds
tests/misc/rge_sm.py:     15.3 seconds -> 2.48 seconds

b63be37be1 stmhal: In safe mode, still mount SD card and present as MSD over USB. 
It's still "safe" because no scripts are run.  Remove the SD card if you
want to access the internal flash filesystem.  Addresses issue #616.

Also: remove obsolete pyb.source_dir setting, and reset pyb.main and
pyb.usb_mode settings on soft-reset.

d779b9642f tests: Wait for just over 1 sec when testing RTC. 
Waiting for 1000ms between seconds of RTC is sometimes too quick.
Waiting for 1001ms is enough for the RTC to pass 1 second.
