Paul Sokolovsky 09ed5bcbbb extmod/modlwip: Rework getaddrinfo() data passing.
The code is based on Damien George's implementation for esp8266 port,
avoids use of global variables and associated re-entrancy issues, and
fixes returning stale data in some cases.
2016-03-12 10:50:51 +07:00
Paul Sokolovsky e5b047369b extmod/modlwip: Use MICROPY_EVENT_POLL_HOOK for event polling if defined.
Instead of just delaying 100ms if event isn't yet ready.

So far applies only to default, "infinite" socket timeout.

Paul Sokolovsky 7379be3673 extmod/modlwip: Add .write() stream method. 2016-03-09 12:35:43 +07:00
Damien George 4f64f6bfd3 extmod/modlwip: Still process remaining incoming data of a closed socket.
It can happen that a socket gets closed while the pbuf is not completely
drained by the application.  It can also happen that a new pbuf comes in
via the recv callback, and then a "peer closed" event comes via the same
callback (pbuf=NULL) before the previous event has been handled.  In both
cases the socket is closed but there is remaining data.  This patch makes
sure such data is passed to the application.
2016-03-09 12:31:25 +07:00
Damien George 6d2e9e70b3 extmod/modlwip: Check for state change during recv busy-wait loop.
For example, the peer may close the connection while recv is waiting for
incoming data.

Paul Sokolovsky e9be6a378c extmod/vfs_fat: Object-oriented encapsulation of FatFs VFS.
This implements OO interface based on existing fsusermount code and with
minimal changes to it, to serve as a proof of concept of OO interface.

Examle of usage:

bdev = RAMFS(48)
uos.VfsFat.mkfs(bdev)
vfs = uos.VfsFat(bdev, "/ramdisk")
f = vfs.open("foo", "w")
f.write("hello!")
f.close()

Paul Sokolovsky bf904b238d extmod/fsusermount: umount: Add NULL pointer checks. 2016-02-13 22:55:35 +02:00
Damien George e372e83b30 extmod/fsusermount: Move BP_IOCTL_xxx constants to fsusermount.h. 2016-02-10 23:40:35 +00:00
Damien George b33a770596 extmod/fsusermount: Support mounting of multiple block devices.
This patch adds support to fsusermount for multiple block devices
(instead of just one).  The maximum allowed is fixed at compile time by
the size of the fs_user_mount array accessed via MP_STATE_PORT, which
in turn is set by MICROPY_FATFS_VOLUMES.

With this patch, stmhal (which is still tightly coupled to fsusermount)
is also modified to support mounting multiple devices   And the flash and
SD card are now just two block devices that are mounted at start up if
they exist (and they have special native code to make them more
efficient).
2016-02-10 23:40:10 +00:00
Damien George 0e0ce47e65 extmod/fsusermount: Expose umount as a public function. 2016-02-10 23:40:10 +00:00

Addresses issue #1835.
2016-02-10 17:05:03 +00:00
Damien George c33ad60a67 extmod/fsusermount: Change block protocol to support ioctl method.
The new block protocol is:
- readblocks(self, n, buf)
- writeblocks(self, n, buf)
- ioctl(self, cmd, arg)

The new ioctl method handles the old sync and count methods, as well as
a new "get sector size" method.

The old protocol is still supported, and used if the device doesn't have
the ioctl method.
2016-02-10 08:59:31 +00:00
Paul Sokolovsky 3846fd56c1 extmod/fsusermount: Implement separate umount() function. 2016-02-10 00:51:47 +02:00
Paul Sokolovsky 5b85a86ce3 extmod/fsusermount: Introduce separate mkfs() function.
Per the previously discussed plan. mount() still stays backward-compatible,
and new mkfs() is rought and takes more args than needed. But is a step
in a forward direction.
2016-02-10 00:50:07 +02:00
Paul Sokolovsky 103fbaaf27 extmod/fsusermount: Common subexpression elimination.

Damien George a53af6c875 extmod/modurandom: Add some extra random functions.
Functions added are:
- randint
- randrange
- choice
- random
- uniform

They are enabled with configuration variable
MICROPY_PY_URANDOM_EXTRA_FUNCS, which is disabled by default.  It is
enabled for unix coverage build and stmhal.

Paul Sokolovsky ee1656e148 extmod/moduhashlib: Add support for SHA1 (based on axTLS).
SHA1 is used in a number of protocols and algorithm originated 5 years ago
or so, in other words, it's in "wide use", and only newer protocols use
SHA2.

The implementation depends on axTLS enabled. TODO: Make separate config
option specifically for sha1().

Damien George 5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.
2016-01-11 00:49:27 +00:00
Damien George 4b72b3a133 py: Change type signature of builtin funs that take variable or kw args.
With this patch the n_args parameter is changed type from mp_uint_t to
size_t.
2016-01-11 00:49:27 +00:00
Damien George a0c97814df py: Change type of .make_new and .call args: mp_uint_t becomes size_t.
This patch changes the type signature of .make_new and .call object method
slots to use size_t for n_args and n_kw (was mp_uint_t.  Makes code more
efficient when mp_uint_t is larger than a machine word.  Doesn't affect
ports when size_t and mp_uint_t have the same size.

Paul Sokolovsky 30b7344eb0 extmod/moduos_dupterm: Make mp_uos_dupterm_tx_strn() function reusable.
Function to actually spool output terminal data to dupterm object.
2016-01-01 16:43:35 +02:00
Paul Sokolovsky ddea7cb702 extmod/moduos_dupterm: Make uos.dupterm() implementation reusable.
That's just function which sets/gets dup terminal object, and can be
easily reused across ports.

Paul Sokolovsky 7203b58e87 extmod/modubinascii: Add "separator" argument to hexlify().
This is extension to CPython, it allows to easily produce human-readable
hex dump:

b'aa 55 aa 55'
2015-12-26 02:15:56 +02:00
Paul Sokolovsky 1b7f622410 extmod/moduhashlib: Add namespace prefix for crypto-algorithms/sha256.h.
Everyone loves to names similar things the same, then there're conflicts
between different libraries. The namespace prefix used is "CRYAL_", which
is weird, and that's good, as that minimizes chance of another conflict.

Dave Hylands 755b01439b unix: machine_mem improvements
This basically introduces the MICROPY_MACHINE_MEM_GET_READ_ADDR

Paul Sokolovsky d4a874b81e extmod/moductypes: sizeof operation depends on layout type of structure.
Previously, sizeof() blindly assumed LAYOUT_NATIVE and tried to align
size even for packed LAYOUT_LITTLE_ENDIAN & LAYOUT_BIG_ENDIAN. As sizeof()
is implemented on a strucuture descriptor dictionary (not an structure
object), resolving this required passing layout type around.

Damien George 999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.

This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

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

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.

argument is a small or big int.

Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

Damien George b1bbe966c4 py: Combine load_attr and store_attr type methods into one (attr).
This simplifies the API for objects and reduces code size (by around 400
bytes on Thumb2, and around 2k on x86).  Performance impact was measured
with Pystone score, but change was barely noticeable.

Damien George 7d414a1b52 py: Parse big-int/float/imag constants directly in parser.
Previous to this patch, a big-int, float or imag constant was interned
(made into a qstr) and then parsed at runtime to create an object each
time it was needed.  This is wasteful in RAM and not efficient.  Now,
these constants are parsed straight away in the parser and turned into
objects.  This allows constants with large numbers of digits (so
addresses issue #1103) and takes us a step closer to #722.

Damien George 0d3cb6726d py: Change vstr so that it doesn't null terminate buffer by default.
This cleans up vstr so that it's a pure "variable buffer", and the user
can decide whether they need to add a terminating null byte.  In most
places where vstr is used, the vstr did not need to be null terminated
and so this patch saves code size, a tiny bit of RAM, and makes vstr
usage more efficient.  When null termination is needed it must be
done explicitly using vstr_null_terminate.

Damien George 05005f679e py: Remove mp_obj_str_builder and use vstr instead.
With this patch str/bytes construction is streamlined.  Always use a
vstr to build a str/bytes object.  If the size is known beforehand then
use vstr_init_len to allocate only required memory.  Otherwise use
vstr_init and the vstr will grow as needed.  Then use
mp_obj_new_str_from_vstr to create a str/bytes object using the vstr
memory.

Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes
on unix x64.

Paul Sokolovsky 2559e13957 moductypes: Make sure we can apply .sizeof() to all aggregate types.
Before, sizeof() could be applied to a structure field only if that field
was itself a structure. Now it can be applied to PTR and ARRAY fields too.
It's not possible to apply it to scalar fields though, because as soon as
scalar field (int or float) is dereferenced, its value is converted into
Python int/float value, and all original type info is lost. Moreover, we
allow sizeof of type definitions too, and there int is used to represent
(scalar) types. So, we have ambiguity what int may be - either dereferenced
scalar structure field, or encoded scalar type. So, rather throw an error
if user tries to apply sizeof() to int.

Dave Hylands 39296b40d4 Fix timer overflow code.
Teensy doesn't need to worry about overflows since all of
its timers are only 16-bit.

For PWM, the pulse width needs to be able to vary from 0..period+1
(pulse-width == period+1 corresponds to 100% PWM)

I couldn't test the 0xffffffff cases since we can't currently get a
period that big in python. With a prescaler of 0, that corresponds
to a freq of 0.039 (i.e. cycle every 25.56 seconds), and we can't
set that using freq or period.

I also tested both stmhal and teensy with floats disabled, which
required a few other code changes to compile.
