Paul Sokolovsky 1129de5ac0 unix: Support readline history saving to file, improves interactive usage. 2015-03-13 21:46:19 +00:00
Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.

This patch adds that feature in all places.  This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

Damien George cd34207409 py: Can compile with -Wmissing-declarations and -Wmissing-prototypes. 2015-01-12 22:30:49 +00:00
Damien George b4b10fd350 py: Put all global state together in state structures.
This patch consolidates all global variables in py/ core into one place,
in a global structure.  Root pointers are all located together to make
GC tracing easier and more efficient.

Paul Sokolovsky 8427c5b76c unix/windows: Make sure that process exit code is portable 8-bit value.
This fixes FORCED_EXIT internal flag leaking into Windows exit code.

Damien George 969a6b37bf py: Make functions static where appropriate. 2014-12-10 22:08:14 +00:00
Paul Sokolovsky 46c3ab2004 modsys: Add sys.print_exception(exc, file=sys.stdout) function.
The function is modeled after traceback.print_exception(), but unbloated,
and put into existing module to save overhead on adding another module.
Compliant traceback.print_exception() is intended to be implemented in
micropython-lib in terms of sys.print_exception().

This change required refactoring mp_obj_print_exception() to take pfenv_t
interface arguments.

Addresses #751.

Damien George a4c52c5a3d py: Optimise lexer by exposing lexer type.
mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer
functions (like checking current token kind) are now inlined.

This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460
bytes on bare-arm.  It also saves a tiny bit of RAM since mp_lexer_t
is a bit smaller.  Also will run a bit more efficiently.

Paul Sokolovsky 6e8ff9cd68 modmicropython: Move mem_info() and qstr_info() functions from unix port.
TODO: Merge useful functionality from modpyb too.

Paul Sokolovsky 98d8d59c33 unix: Allow -X heapsize number take 'w' specifier for word size adjustment.
The specifier should go after the number, before size suffix like 'k' or 'm'.
E.g.: "-X heapsize=100wk" will use 100K heap on 32-bit system and 200K - on
64-bit.

Paul Sokolovsky 429e3f077e unix: Make -v dump memory info at exit.
Also, move bytecode dumps to -v -v, because they're too verbose for just -v.

Paul Sokolovsky e503512f83 unix: Implement -m option (execute module from stdlib).
Support for packages as argument not implemented, but otherwise error and
exit handling should be correct. This for example will allow to do:

pip-micropython install micropython-test.pystone
micropython -m test.pystone

Damien George c76af32575 unix/windows: Disable sigaction on windows port. 2014-10-26 00:42:41 +01:00
Damien George 124df6f8d0 py: Add mp_pending_exception global variable, for VM soft interrupt.
This allows to implement KeyboardInterrupt on unix, and a much safer
ctrl-C in stmhal port.  First ctrl-C is a soft one, with hope that VM
will notice it; second ctrl-C is a hard one that kills anything (for
both unix and stmhal).

One needs to check for a pending exception in the VM only for jump
opcodes.  Others can't produce an infinite loop (infinite recursion is
caught by stack check).

Paul Sokolovsky fcff4663dd unix: Allow -X heapsize= option take numbers with K & M suffixes.
For kilobytes and megabytes respectively.

Damien George 0b13f3e026 py: Improve memory usage debugging; better GC AT dumping.
In unix port, mem_info(1) now prints pretty GC alloc table.

Paul Sokolovsky 23b3b04072 unix: Rename "microsocket" module to "usocket".
Per new conventions, we'd like to consistently use "u*" naming conventions
for modules which don't offer complete CPython compatibility, while offer
subset or similar API.

Damien George b0261341d3 py: For malloc and vstr functions, use size_t exclusively for int type.
It seems most sensible to use size_t for measuring "number of bytes" in
malloc and vstr functions (since that's what size_t is for).  We don't
use mp_uint_t because malloc and vstr are not Micro Python specific.

Damien George b92cbe6129 py: Move definition of mp_sys_exit to core.
sys.exit always raises SystemExit so doesn't need a special
implementation for each port.  If C exit() is really needed, use the
standard os._exit function.

Also initialise mp_sys_path and mp_sys_argv in teensy port.

Damien George 3c658a4e75 py: Fix bug where GC collected native/viper/asm function data.
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

Damien George 8f81b5cb4b py: Put SystemExit in builtin namespace.
Also fix unix port so that SystemExit with no arg exits with value 0.

Damien George 8dbbbbc793 Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.
qstr_init is always called exactly before mp_init, so makes sense to
just have mp_init call it.  Similarly with
mp_init_emergency_exception_buf.  Doing this makes the ports simpler and
less error prone (ie they can no longer forget to call these).

Paul Sokolovsky d0f5e61ab5 py: Implement __file__ attribute for modules. 2014-07-28 21:21:59 +03:00
Dave Hylands 5b7fd20fea Add support for storing args during an exception raised by an irq.
The user code should call micropython.alloc_emergency_exception_buf(size)
where size is the size of the buffer used to print the argument
passed to the exception.

With the test code from #732, and a call to
micropython.alloc_emergenncy_exception_buf(100) the following error is
now printed:
```python
>>> import heartbeat_irq
Uncaught exception in Timer(4) interrupt handler
Traceback (most recent call last):
  File "0://heartbeat_irq.py", line 14, in heartbeat_cb
NameError: name 'led' is not defined

stijn ec6fa8732b windows: Sync mpconfigport.h with the unix' version
- rearrange/add definitions that were not there so it's easier to compare both

- define EWOULDBLOCK, it is missing from ingw32

Paul Sokolovsky 8a96ebea75 py: Move stack_ctrl_init() to mp_init().
As stack checking is enabled by default, ports which don't call
stack_ctrl_init() are broken now (report RuntimeError on startup). Save
them trouble and just init stack control framework in interpreter init.

Paul Sokolovsky 23668698cb py: Add portable framework to query/check C stack usage.
Such mechanism is important to get stable Python functioning, because Python
function calling is handled with C stack. The idea is to sprinkle
STACK_CHECK() calls in places where there can be C recursion.

TODO: Add more STACK_CHECK()'s.
