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

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.

8175877ad6 unix/modtime: strftime(): Support 2nd argument, but as time_t value.
Instead of struct tm like structure, as required by CPython.

8fb255dc34 unix/modtime: Add strftime() function (only single argument is supported).
Following "don't rely on FFI for basic functionality" approach.

3376875bc8 unix/modtime: sleep(): Return early if KeyboardInterrupt is pending
As set by signal handler. This assumes that exception will be raised
somewhere else, which so far doesn't happen for single function call.
Still, it makes sense to handle that in some common place.

0bb57bf5bf unix/modtime: sleep(): Automatically restart after receiving EINTR.
THis is required to deal well with signals, signals being the closest
analogue of hardware interrupts for POSIX. This is also CPython 3.5
compliant behavior (PEP 475).

The main problem implementing this is to figure out how much time was
spent in waiting so far/how much is remaining. It's well-known fact that
Linux updates select()'s timeout value when returning with EINTR to the
remaining wait time. Here's what POSIX-based standards say about this:
(http://pubs.opengroup.org/onlinepubs/9699919799/functions/pselect.html):

"Upon successful completion, the select() function may modify the object
pointed to by the timeout argument."

I.e. it allows to modify timeout value, but doesn't say how exactly it is
modified. And actually, it allows such modification only "upon successful
completion", which returning with EINTR error hardly is.

POSIX also allows to request automatic EINTR restart for system calls using
sigaction call with SA_RESTART flag, but here's what the same document says
about it:

"If SA_RESTART has been set for the interrupting signal, it is
implementation-defined whether the function restarts or returns with
[EINTR]."

In other words, POSIX doesn't leave room for both portable and efficient
handling of this matter, so the code just allows to manually select
Linux-compatible behavior with MICROPY_SELECT_REMAINING_TIME option,
or otherwise will just raise OSError. When systems with non-Linux behavior
are found, they can be handled separately.

8ee153f234 unix/modtime: Implement ticks_ms(), ticks_us() and ticks_diff().
All of these functions return positive small int, thus range is 2 bits less
than word size (30 bit on 32-bit systems, 62 bit on 64-bit systems).

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.

f6932d6506 Prefix ARRAY_SIZE with micropython prefix MP_ 2014-06-19 18:54:34 +02:00

585a3394df - Cast the struct stat sb.st_ino field to machine_int_t explicitly to avoid a
cast error in MP_OBJ_NEW_SMALL_INT(). This is necessary for FreeBSD, where
  st_ino is of different size
- If MP_CLOCKS_PER_SEC is defined on the target host, simply define CLOCK_DIV
  as a fraction, regardless of the value of MP_CLOCKS_PER_SEC.
  FreeBSD uses a non-POSIX compliant value of 128 for CLOCKS_PER_SEC

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.

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/.
