Paul Sokolovsky edc02bd952 unix/main: Implement -m option for packages. 2017-05-09 14:22:21 +03:00
Paul Sokolovsky c1e0eb7afe unix/main: Don't allow to specify too small heap size.
This will lead to crash like:

FATAL: uncaught NLR 80a5420

On x86_32, the minimum heap size is smaller, but not 2 times, so just
use value which works for x86_64.

Paul Sokolovsky 11bc21dfa8 unix/main: Ignore SIGPIPE signal, instead make EPIPE arrive.
Do not raise SIGPIPE, instead return EPIPE. Otherwise, e.g. writing
to peer-closed socket will lead to sudden termination of MicroPython
process. SIGPIPE is particularly nasty, because unix shell doesn't
print anything for it, so the above looks like completely sudden and
silent termination for unknown reason. Ignoring SIGPIPE is also what
CPython does. Note that this may lead to problems using MicroPython
scripts as pipe filters, but again, that's what CPython does. So,
scripts which want to follow unix shell pipe semantics (where SIGPIPE
means "pipe was requested to terminate, it's not an error"), should
catch EPIPE themselves.

Damien George 6c564aa408 unix, windows: Use core-provided KeyboardInterrupt exception object. 2017-04-11 13:31:49 +10:00
Damien George 46e98d9ea7 unix: Convert mp_uint_t to size_t for use of mp_obj_list_get. 2017-03-29 12:56:17 +11:00
Damien George 33a77ea25f unix/main: Refactor to put lexer constructors all in one place.
The lexer can now raise an exception on construction so it must go within
an nlr handler block.

Damien George 5e83a75c78 unix: Remove remaining, obsolete traces of GNU readline support. 2017-03-03 17:55:40 +11:00
Paul Sokolovsky de48a27d60 unix/main: Properly handle MICROPYPATH starting with ':'.
In other words, where first path component is an empty string.

Damien George ebb8413178 unix/main: Allow to print the parse tree in coverage build.
Passing -v -v -v on the command line of the coverage build will now print
the parse tree (as well as other things at this verbosity level).

Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.

Paul Sokolovsky 520f35632d unix/main: When preparing sys.path, allocate exact strings on uPy heap.
Due to the way modern compilers work (allocating space for stack vars once
at tha start of function, and deallocating once on exit from), using
intermediate stack buffer of big size caused blockage of 4K (PATH_MAX)
on stack for the entire duration of MicroPython execution.

Paul Sokolovsky 649b69a1db unix/main: Improve help for -X options a bit. 2016-07-08 20:53:08 +03:00
Paul Sokolovsky 0e5e14fe7c unix/main: Error out on unknown value of suffix in -X heapsize= option.
E.g. -X heapsize=16Kfoo, -X heapsize=1G will lead to error.

Pavol Rusnak 3d4a535208 unix: implement -i option (inspect - start REPL after script is finished) 2016-04-01 12:35:45 +03:00
Paul Sokolovsky d3b1f0b627 py/runtime: mp_stack_ctrl_init() should be called immediately on startup.
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).

Paul Sokolovsky 30b7344eb0 extmod/moduos_dupterm: Make mp_uos_dupterm_tx_strn() function reusable.
Function to actually spool output terminal data to dupterm object.

Paul Sokolovsky 5efd3f0dca windows: Make keyboard_interrupt_obj available, it's standard feature. 2015-12-18 01:07:27 +02:00
Paul Sokolovsky 3a309d93b1 unix/main: mp_verbose_flag available only if MICROPY_DEBUG_PRINTERS is true.
Not available for minimal build for example.
2015-12-07 20:09:20 +02:00
Paul Sokolovsky 5ae3ddcc9a unix/main: Check pending exception at the end of code block execution.
Usually this checking is done by VM on jump instructions, but for linear
sequences of instructions and builtin functions this won't happen. Particular
target of this change is long-running builtin functions like time.sleep().

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 9f10d3fb63 unix/main: Get rid of perror() which uses stdio. 2015-11-23 00:10:38 +02:00
Paul Sokolovsky c3280d83e7 unix: Use printf() implementation in terms of mp_printf().
In other words, unix port now uses overriden printf(), instead of using
libc's. This should remove almost all dependency on libc stdio (which
is bloated).

Paul Sokolovsky 295ea12411 py/emitglue: Host definition of mp_verbose_flag.
This may not seem like the ideal place, but is actually the only place
in py/ where it gets referenced, so is just right.

Paul Sokolovsky a01f6c9ae7 unix/main: Remove stray mp_printf() from previous commit. 2015-11-13 17:33:42 +02:00
Paul Sokolovsky 3a6b3d230c main.c: Switch stderr printing from ANSI C to native POSIX. 2015-11-13 15:29:42 +02:00
Paul Sokolovsky f882d53fcd unix/main: Use builtin unichar_isdigit() in preference if libc's.
Less dependencies.
2015-11-13 01:57:08 +02:00
Damien George 731f359292 all: Add py/mphal.h and use it in all ports.
py/mphal.h contains declarations for generic mp_hal_XXX functions, such
as stdio and delay/ticks, which ports should provide definitions for.  A
port will also provide mphalport.h with further HAL declarations.

Damien George 0334058fa4 Rename "Micro Python" to "MicroPython" in REPL, help, readme's and misc. 2015-10-12 00:06:25 +01:00
Damien George 46a1102852 repl: Add paste mode to friendly REPL, entered via CTRL-E.
Use CTRL-E to enter paste mode.  Prompt starts with "===" and accepts
all characters verbatim, echoing them back.  Only control characters are
CTRL-C which cancels the input and returns to normal REPL, and CTRL-D
which ends the input and executes it.  The input is executed as though
it were a file.  The input is not added to the prompt history.

Damien George 58e0f4ac50 py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.
With this patch parse nodes are allocated sequentially in chunks.  This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.

Saves roughly 20% of RAM during parse stage.

Alex March c0035d1694 unix: Use MICROPY_HAL_H macro for header inclusion.
Follow the same format as other ports using the macro to include
the HAL header.

Paul Sokolovsky 51726b4d43 unix: Allow to override default sys.path value.
Using MICROPY_PY_SYS_PATH_DEFAULT macro define. A usecase is building a
distribution package, which should not have user home path by default in
sys.path. In such case, MICROPY_PY_SYS_PATH_DEFAULT can be defined on
make command-line (using CFLAGS_EXTRA).

Damien George 9ae3fc6523 unix: Add option to use uPy readline, and enable by default.
This gets uPy readline working with unix port, with tab completion and
history.  GNU readline is still supported, configure using
MICROPY_USE_READLINE variable.

Damien George d792d9e49e unix: Make extra-coverage function callable from Python scripts.
This allows the output of the extra-coverage tests to be checked using
the normal run-tests script.
2015-05-08 09:18:38 +01:00
Damien George d3b32caea4 unix: Add special function to improve coverage.
The function and corresponding command-line option are only enabled for
the coverage build.  They are used to exercise uPy features that can't
be properly tested by Python scripts.

Damien George 95f53461c2 py: Replace py-version.sh with makeversionhdr.py, written in Python.
Also rename py-version.h to mpversion.h for consistency with mpconfig.h.

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.
