Yonatan Goldschmidt c2fb725e72 extmod/moduhashlib: Make function objects STATIC.
These are not exported to anyone anyway.

Yonatan Goldschmidt 6963ee9075 extmod/moduhashlib: Allow using the sha256 implementation of mbedTLS. 2018-06-12 13:50:11 +10:00
Yonatan Goldschmidt 6630354ffe extmod/moduhashlib: Allow to disable the sha256 class.
Via the config value MICROPY_PY_UHASHLIB_SHA256.  Default to enabled to
keep backwards compatibility.

Also add default value for the sha1 class, to at least document its
existence.

Yonatan Goldschmidt 38682d4629 extmod/moduhashlib: Reorder funcs so that they are grouped by hash type.
Makes the code much more readable by reducing the number of #ifdefs and
keeping related functions close.

Yonatan Goldschmidt b045ebd354 extmod/moduhashlib: Prefix all Python methods and objects with uhashlib.
For consistency with other modules, and to help avoid clashes with the
actual underlying functions that do the hashing (eg
crypto-algorithms/sha256.c:sha256_update).

Jeff Epler 11a97bdffe uhashlib: masquerade as hashlib for python3 compatibility 2018-05-06 12:31:54 -05:00
Jeff Epler 005226ae54 uhashlib: some functions should refuse unicode for python3 compatibility
.. this maybe should be subject to MICROPY_CPYTHON_COMPAT, except that
is not defined in the main circuitpython ports so it would be a change
that makes no difference.

Christopher Cooper 7413b3ce3e extmod/moduhashlib: Enable SHA1 hashing when using "mbedtls" library.
The SHA1 hashing functionality is provided via the "axtls" library's
implementation, and hence is unavailable when the "axtls" library is not being
used.  This change provides the same SHA1 hashing functionality when using the
"mbedtls" library by using its implementation instead.

Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George 93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct.
One can instead lookup __name__ in the modules dict to get the value.

Paul Sokolovsky f5c42dd9d1 extmod/moduhashlib: Use MICROPY_PY_UHASHLIB_SHA1 config define. 2016-01-25 00:49:00 +02:00
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.

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 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.

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 2fddc68fdf moduhashlib: Remove not implemented .hexdigest().
Effect can be easily achieved by ubinsacii.hexlify(hash.digest()).

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.

Damien George 3b603f29ec Use MP_DEFINE_CONST_DICT macro to define module dicts.
This is just a clean-up of the code.  Generated code is exactly the
same.
