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.

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.

Damien George 04353cc85e py: With obj repr "C", change raw str accessor from macro to function.
This saves around 1000 bytes (Thumb2 arch) because in repr "C" it is
costly to check and extract a qstr.  So making such check/extract a
function instead of a macro saves lots of code space.

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 c2a4e4effc py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument.  Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.

This lead to quite a bit of code cleanup, and should be more efficient
if anything.  It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.

The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".

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.

Paul Sokolovsky ac2f7a7f6a objstr: Add .splitlines() method.
splitlines() occurs ~179 times in CPython3 standard library, so was
deemed worthy to implement. The method has subtle semantic differences
from just .split("\n"). It is also defined as working for any end-of-line
combination, but this is currently not implemented - it works only with
LF line-endings (which should be OK for text strings on any platforms,
but not OK for bytes).

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.

Paul Sokolovsky 344e15b1ae objstr: Remove code duplication and unbreak Windows build.
There was really weird warning (promoted to error) when building Windows
port. Exact cause is still unknown, but it uncovered another issue:
8-bit and unicode str_make_new implementations should be mutually exclusive,
and not built at the same time. What we had is that bytes_decode() pulled
8-bit str_make_new() even for unicode build.

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.

This behaviour follows Python 3.5 standard (in 3.4 it's a
DeprecationWarning which we'd rather make a TypeError).
2014-06-05 19:44:54 +01:00
Damien George 11de8399fe py: Small changes to objstr.c, including a bug fix.
Some small fixed:

- Combine 'x' and 'X' cases in str format code.

- Remove trailing spaces from some lines.

- Make exception messages consistently begin with lower case (then
needed to change those in objarray and objtuple so the same
constant string data could be used).

- Fix bug with exception message having %c instead of %%c.

Paul Sokolovsky 75ce9256b2 objstr: Implement "%(key)s" % {} formatting for strings and dicts.
Also, make sure that args to "*" format specifiers are bounds-checked
properly and don't lead for segfaults in case of mismatch.

Chris Angelico 4867413e69 Simplify detection of quote characters in mp_str_print_quoted.
Once a double quote has been found, the subsequent discovery of a single quote
won't change behaviour at all, so don't bother looking for one.
2014-06-04 03:26:40 +10:00
Damien George fcc9cf63f1 py, str: Replace enum with actual function pointer.
This way, it's slightly more efficient, uses less ROM (60 bytes less
for stmhal), and doesn't require to raise exception if bad operation
given.
2014-06-01 18:22:09 +01:00
Damien George fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*.
This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT

See issue #35 for discussion.

Paul Sokolovsky bcdffe53c6 objstr: *strip(): Fix handling of one-char subject strings. 2014-05-30 03:15:17 +03:00
Damien George f600a6a085 py: Slightly improve efficiency of mp_obj_new_str; rename str_new.
Reorder interning logic in mp_obj_new_str, to be more efficient.

str_new is globally accessible, so should be prefixed with mp_obj_.
2014-05-25 22:34:34 +01:00
Damien George 2617eebf2f Change const byte* to const char* where sensible.
This removes need for some casts (at least, more than it adds need
for new casts!).

Paul Sokolovsky afaaf535e6 objslice: Support arbitrary objects start, stop, and step.
Older int-only encoding is not expressive enough to support arbitrary slice
assignment operations.
2014-05-25 01:42:24 +03:00
Damien George ee3fd46f13 Rename configuration variables controling Python features.
Now of the form MICROPY_PY_*.  See issue #35.
2014-05-24 23:03:12 +01:00
Paul Sokolovsky d098c6bf85 objstr: Implement .endswith(). 2014-05-24 22:46:51 +03:00
Damien George 6ac5dced24 py: Rename MP_OBJ_NOT_SUPPORTED to MP_OBJ_NULL.
See issue #608 for justification.

Paul Sokolovsky a47b64ae2d objstringio: Implement io.BytesIO.
Done in generalized manner, allowing any stream class to be specified as
working with bytes.
2014-05-15 07:28:19 +03:00
Paul Sokolovsky 2a27365854 objstr.c: Partial implementation of .rsplit().

Paul Sokolovsky eea0118654 py: Give up and make mp_obj_str_get_data() deal with bytes too.
This is not fully correct re: error handling, because we should check that
that types are used consistently (only str's or only bytes), but magically
makes lot of functions support bytes.
2014-05-11 13:51:24 +03:00
Paul Sokolovsky b2d4fc06fc objstr: Make *strip() accept bytes. 2014-05-11 13:17:29 +03:00

Paul Sokolovsky 7b0f9a7d9b bytes: Implement comparison and other binary operations.
Should support everything supported by strings.
2014-05-10 04:45:02 +03:00
Paul Sokolovsky b473d0ae86 py: bytes(), str(): Add NotImplementedError for kwargs.
Addresses #567.
2014-05-06 19:31:58 +03:00
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.
2014-05-02 17:48:40 +03:00

Paul Sokolovsky 504e23388c objstr: Init hash in mp_obj_str_builder_start() to 0. 2014-04-19 03:21:06 +03:00
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.
2014-04-18 22:29:21 +01:00
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.
2014-04-17 23:19:36 +01:00
Damien George 729f7b42d6 py: Merge BINARY_OP_SUBSCR and store_subscr (w/ delete) into subscr.

Disabled by default.  Enabled in unix port.
2014-04-14 21:20:30 +01:00
Paul Sokolovsky 58676fc2c7 objstr: Allow to define statically allocated str objects.
Similar to tuples, lists, dicts. Statically allocated strings don't have hash
computed.
2014-04-14 01:45:06 +03:00
Paul Sokolovsky 59e269cfec qstr, objstr: Make sure that valid hash != 0, treat 0 as "not computed".
This feature was proposed with initial hashing RFC, and is prerequisite for
seamless static str object definition.
