Delio Brignoli cceff157dd qemu-arm: Enable array slice assignment to get memoryview1 test to pass. 2015-07-20 15:53:22 +01:00
Delio Brignoli 32aba40830 py: Implement memoryview slice assignment.
Adds ability to do "memcpy" with memoryview objects, such as:
m1[0:3] = m2[2:5].

Damien George f576057274 stmhal: Add CMSIS device header files for STM32F2xx series. 2015-07-20 12:33:05 +01:00
Wojtek Siudzinski 0621eca05e stmhal: Add STM32CubeF2 version 1.1.0, in hal/f2 directory.
Only those files which are needed by the stmhal port are added.

Also includes a dummy file (stm32f2xx_hal_pcd_ex.c) to keep the build
system the same for f4 and f2 MCU series.

Damien George a39df51d8a stmhal: Update Makefile and board configs to compile with relocated hal. 2015-07-20 12:30:18 +01:00
Damien George e4d43401eb stmhal: Move HAL Cube files to f4/ subdir, keeping only those we use.
This is in preparation for supporting other MCU series, such as
STM32F2xx.  Directory structure for the HAL is now hal/f4/{inc,src},
where "f4" will in the future be different for other series.

HAL source/header files that are not use are removed to reduce the size
of the code.

Damien George c3bd9415cc py: Make qstr hash size configurable, defaults to 2 bytes.
This patch makes configurable, via MICROPY_QSTR_BYTES_IN_HASH, the
number of bytes used for a qstr hash.  It was originally fixed at 2
bytes, and now defaults to 2 bytes.  Setting it to 1 byte will save
ROM and RAM at a small expense of hash collisions.

Daniel Campora f22b35e4e5 cc3200: Add socket.sendall() (aliases to send()).
Simplelink's socket send checks for the size of the packet and sends
it in chunks if the size is too large.

Dave Hylands 9309e609cd stmhal: Add qstr definition for ifconfig when building for WizNet 2015-07-14 23:00:29 +01:00
Damien George ade9a05236 py: Improve allocation policy of qstr data.
Previous to this patch all interned strings lived in their own malloc'd
chunk.  On average this wastes N/2 bytes per interned string, where N is
the number-of-bytes for a quanta of the memory allocator (16 bytes on 32
bit archs).

With this patch interned strings are concatenated into the same malloc'd
chunk when possible.  Such chunks are enlarged inplace when possible,
and shrunk to fit when a new chunk is needed.

RAM savings with this patch are highly varied, but should always show an
improvement (unless only 3 or 4 strings are interned).  New version
typically uses about 70% of previous memory for the qstr data, and can
lead to savings of around 10% of total memory footprint of a running
script.

Costs about 120 bytes code size on Thumb2 archs (depends on how many
calls to gc_realloc are made).

Paul Sokolovsky c48740e20b unix: modsocket: Implement inet_pton() in preference of inet_aton().
inet_pton supports both ipv4 and ipv6 addresses. Interface is also extensible
for other address families, but underlying libc inet_pton() function isn't
really extensible (e.g., it doesn't return length of binary address, i.e. it's
really hardcoded to AF_INET and AF_INET6). But anyway, on Python side, we could
extend it to support other addresses.

Paul Sokolovsky 3b83aeb403 unix: modsocket: Implement sendto().
sendto() turns out to be mandatory function to work with UDP. It may seem
that connect(addr) + send() would achieve the same effect, but what connect()
appears to do is to set source address filter on a socket to its argument.
Then everything falls apart: socket sends to a broad-/multi-cast address,
but reply is sent from real peer address, which doesn't match filter set
by connect(), so local socket never sees a reply.

Paul Sokolovsky 354d17523f modmachine: Implement physical memory access using /dev/mem (Linux, etc).
This requires root access. And on recent Linux kernels, with
CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in
/proc/iomem can be accessed. The above compiled-time option can be
however overriden with boot-time option "iomem=relaxed".

This also removed separate read/write paths - there unlikely would
be a case when they're different.

Update pydfu.py to match with the version from openmv.

I just updated the openmv version to work with both of the
PyUSB 1.0.0.b1 and 1.0.0.b2

Dave Hylands 9f76dcd682 py: Prevent many extra vstr allocations.
I checked the entire codebase, and every place that vstr_init_len
was called, there was a call to mp_obj_new_str_from_vstr after it.

mp_obj_new_str_from_vstr always tries to reallocate a new buffer
1 byte larger than the original to store the terminating null
character.

In many cases, if we allocated the initial buffer to be 1 byte
longer, we can prevent this extra allocation, and just reuse
the originally allocated buffer.

Asking to read 256 bytes and only getting 100 will still cause
the extra allocation, but if you ask to read 256 and get 256
then the extra allocation will be optimized away.

Yes - the reallocation is optimized in the heap to try and reuse
the buffer if it can, but it takes quite a few cycles to figure
this out.

Note by Damien: vstr_init_len should now be considered as a
string-init convenience function and used only when creating
null-terminated objects.

Damien George ef7dd8db2d py/repl: Fix case where shorter names are shadowed by longer names.
Previous to this patch, if "abcd" and "ab" were possible completions
to tab-completing "a", then tab would expand to "abcd" straight away
if this identifier appeared first in the dict.
