Damien George a75b02ea9b py: Improve efficiency of MP_OBJ_IS_STR_OR_BYTES.
Saves ROM (16 on stmhal, 240 on 64-bit unix) and should be quicker since
there is 1 less branch.

Dave Hylands b7f7c655ed Make int(b'123') work properly. 2014-08-26 19:15:04 -07:00
Damien George 9b7a8ee8f1 py: Fix mult by negative number of tuple, list, str, bytes.
Multiplication of a tuple, list, str or bytes now yields an empty
sequence (instead of crashing).  Addresses issue #799

Also added ability to mult bytes on LHS by integer.

Damien George d1e355ea8e py: Fix check of small-int overflow when parsing ints.
Also unifies use of SMALL_INT_FITS macro across parser and runtime.

Addresses issue #627.

Paul Sokolovsky ab7bf28489 py: More const usage. 2014-05-17 11:20:10 +03:00
Damien George ee7a880d6e py: Use mp_arg_check_num in more places.
Updated functions now do proper checking that n_kw==0, and are simpler
because they don't have to explicitly raise an exception.  Down side is
that the error messages no longer include the function name, but that's
acceptable.

Saves order 300 text bytes on x64 and ARM.

Damien George a32c1e41cc py: Improve native emitter; now supports more opcodes. 2014-05-07 18:30:52 +01:00
Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
2014-05-03 23:27:38 +01:00
Paul Sokolovsky f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.
Specifically, nlr.h does.

Damien George b11b85adaa py: Allow to pass buffer protocol flags to get_buffer helper funcs. 2014-04-18 22:59:24 +01:00
Damien George 57a4b4f178 py: Add typecode to buffer protocol.
When querying an object that supports the buffer protocol, that object
must now return a typecode (as per binary.[ch]).  This does not have to
be honoured by the caller, but can be useful for determining element
size.

Damien George ea8d06c39d py: Add MP_OBJ_STOP_ITERATION and make good use of it.
Also make consistent use of MP_OBJ_NOT_SUPPORTED and MP_OBJ_NULL.
This helps a lot in debugging and understanding of function API.

Damien George b9e7ed4ebc py: Oops, fix int.from_bytes to correctly convert bytes! 2014-04-13 12:40:50 +01:00
Damien George 5213eb35b5 py: Make int.from_bytes a classmethod; support arbitrary length buf. 2014-04-13 12:24:13 +01:00
Damien George 88d7bba961 py: Make it so that printing a small int does not allocate heap memory.
With the implementation of proper string formatting, code to print a
small int was delegated to mpz_as_str_inpl (after first converting the
small int to an mpz using stack memory).  But mpz_as_str_inpl allocates
heap memory to do the conversion, so small ints needed heap memory just
to be printed.

This fix has a separate function to print small ints, which does not
allocate heap, and allocates less stack.

String formatting, printf and pfenv are now large beasts, with some
semi-duplicated code.
2014-04-08 23:30:46 +01:00
Paul Sokolovsky a985b4593d objint: Implement int.from_bytes() class method and .to_bytes() method.
These two are apprerently the most concise and efficient way to convert
int to/from bytes in Python. The alternatives are struct and array modules,
but methods using them are more verbose in Python code and less efficient
in memory/cycles.

Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Damien George 9d68e9ccdd py: Implement integer overflow checking for * and << ops.
If operation will overflow, a multi-precision integer is created.
2014-03-12 15:38:15 +00:00
Damien George 438c88dd2f Add arbitrary precision integer support.
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).

Damien George 2613ffde43 py: Rename strtonum to mp_strtonum.
strtonum clashes with BSD function of same name, and our version is
different so warrants a unique name.  Addresses Issue #305.

Damien George 0379b55ab0 py: Fix casting and printing of small int. 2014-02-22 17:34:09 +00:00
Damien George c5966128c7 Implement proper exception type hierarchy.
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of.  When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).

Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.

Handling of parse error changed to match new exceptions.

mp_const_type renamed to mp_type_type for consistency.
2014-02-15 16:10:44 +00:00
Damien George a71c83a1d1 Change mp_obj_type_t.name from const char * to qstr.
Ultimately all static strings should be qstr.  This entry in the type
structure is only used for printing error messages (to tell the type of
the bad argument), and printing objects that don't supply a .print method.

Damien George 099a9cb575 Remove mp_obj_new_exception_msg_1_arg and _2_arg. 2014-02-12 23:02:19 +00:00
Paul Sokolovsky d5df6cd44a Replace global "static" -> "STATIC", to allow "analysis builds". Part 1.
Some tools do not support local/static symbols (one example is GNU ld map file).
Exposing all functions will allow to do detailed size comparisons, etc.

Also, added bunch of statics where they were missing, and replaced few identity
functions with global mp_identity().
2014-02-12 18:21:11 +02:00
Damien George 698ec21e46 Make mp_obj_str_get_data return char* instead of byte*.
Can't decide which is better for string type, char or byte pointer.
Changing to char removes a few casts.  Really need to do proper unicode.

Can now have null bytes in strings.  Can define ROM qstrs per port using

Paul Sokolovsky d26b379eec int: Add value accessors: mp_obj_int_get() & mp_obj_int_get_checked().
mp_obj_int_get() can be used when just full resolution of C machine_int_t
is required (returns truncated value of long int). mp_obj_int_get_checked()
will throw exception if Python int value not representable in machine_int_t.
