suspect-devices/circuitpython/py, branch v1.8.6 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.8.6 2016-11-08T03:36:06+00:00 py: Strip leading dirs from frozen mpy files, so any path can be used. 2016-11-08T03:36:06+00:00 Damien George damien.p.george@gmail.com 2016-11-08T03:36:06+00:00 urn:sha1:fcda6a2a786eeddc78af5493d28c0054a43027c9 With this patch one can now do "make FROZEN_MPY_DIR=../../frozen" to specify a directory containing scripts to be frozen (as well as absolute paths). The compiled .mpy files are now stored in $(BUILD)/frozen_mpy/. py: Move frozen bytecode Makefile rules from ports to common mk files. 2016-11-08T03:28:30+00:00 Damien George damien.p.george@gmail.com 2016-11-08T03:28:30+00:00 urn:sha1:bdf33bc1367fa6fc888c791ce00b326bbd279bdf Now, to use frozen bytecode all a port needs to do is define FROZEN_MPY_DIR to the directory containing the .py files to freeze, and define MICROPY_MODULE_FROZEN_MPY and MICROPY_QSTR_EXTRA_POOL. py: Add MICROPY_FLOAT_CONST macro for defining float constants. 2016-11-03T01:33:01+00:00 Damien George damien.p.george@gmail.com 2016-11-03T01:33:01+00:00 urn:sha1:561844f3ba2dc81ce37c58468099042e27cd422b All float constants in the core should use this macro to prevent unnecessary creation of double-precision floats, which makes code less efficient. py: Change config default so m_malloc0 uses memset if GC not enabled. 2016-11-02T23:16:31+00:00 Colin Hogben colin@infinnovation.co.uk 2016-10-31T14:52:11+00:00 urn:sha1:828df54bfeaa4a31040fa534dd2961cc9b4ac16e With MICROPY_ENABLE_GC set to false the alternate memory manager may not clear all memory that is allocated, so it must be cleared in m_malloc0. py: Fix wrong assumption that m_renew will not move if shrinking 2016-11-02T12:15:41+00:00 Colin Hogben colin@infinnovation.co.uk 2016-10-31T14:05:56+00:00 urn:sha1:f9b6b37cf65c4f65c4ad461d439fbf624c0f10c1 In both parse.c and qstr.c, an internal chunking allocator tidies up by calling m_renew to shrink an allocated chunk to the size used, and assumes that the chunk will not move. However, when MICROPY_ENABLE_GC is false, m_renew calls the system realloc, which does not guarantee this behaviour. Environments where realloc may return a different pointer include: (1) mbed-os with MBED_HEAP_STATS_ENABLED (which adds a wrapper around malloc & friends; this is where I was hit by the bug); (2) valgrind on linux (how I diagnosed it). The fix is to call m_renew_maybe with allow_move=false. unix: fix symbol references for x86 Mac 2016-11-01T21:42:04+00:00 Jan Pochyla jpochyla@gmail.com 2016-06-02T17:10:39+00:00 urn:sha1:ffb04a5845d2b24b99260d72ea8b99d9425ee1b4 py: remove asserts that are always true in emitbc.c 2016-10-31T20:21:22+00:00 Pavol Rusnak stick@gk2.sk 2016-10-25T09:05:33+00:00 urn:sha1:7ffc959c00707c8328d3e8235e9c4741f227c25c py: fix null pointer dereference in mpz.c, fix missing va_end in warning.c 2016-10-31T20:21:15+00:00 Pavol Rusnak stick@gk2.sk 2016-10-25T09:03:39+00:00 urn:sha1:3679ee9b520db96772ef0917d0a108180aa70114 py/sequence: Fix reverse slicing of lists. 2016-10-30T17:54:19+00:00 Fabio Utzig utzig@utzig.org 2016-10-30T16:25:04+00:00 urn:sha1:8908e505ce23ccd1f0ee49f3ffa80bf78cfaccfa extmod/utime_mphal: Allow ticks functions period be configurable by a port. 2016-10-30T00:02:07+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-10-30T00:02:07+00:00 urn:sha1:76146b3d9ab0ab88ce0f0d1cfa0235ec0758a4a9 Using MICROPY_PY_UTIME_TICKS_PERIOD config var.
