Damien George 564963a170 py: Fix debug-printing of bytecode line numbers. 
Also move the raw bytecode printing code from emitglue to mp_bytecode_print.

Damien George d00d8ac95c py: Use mp_uint_t where appropriate in stream functions. 2014-10-24 11:26:12 +00:00
Paul Sokolovsky e2f8d98525 stream: Add optional 2nd "length" arg to .readinto() - extension to CPython. 
While extension to file.readinto() definition of CPython, the additional arg
is similar to what in CPython available in socket.recv_into().

Damien George e7bb0443cd py: Properly free string parse-node; add assertion to gc_free. 2014-10-23 14:13:05 +01:00
Damien George dd4f4530ab py: Add builtin memoryview object (mostly using array code). 2014-10-23 13:34:35 +01:00
Damien George 3aa09f5784 py: Use MP_OBJ_NULL instead of NULL in a few places. 2014-10-23 12:06:53 +01:00
Damien George 37378f8a9d py: Clean up edge cases of malloc/realloc/free. 2014-10-23 12:02:00 +01:00
Damien George f5d69794a8 extmod: Add uheapq module. 2014-10-22 23:20:15 +01:00
Damien George e72be1b999 py: Fix smallint modulo with negative arguments. 
Addresses issue #927.
 2014-10-22 23:05:50 +01:00
Damien George e7a478204a py: Remove unused and unneeded SystemError exception. 
It's purpose is for internal errors that are not catastrophic (ie not as
bad as RuntimeError).  Since we don't use it, we don't need it.
 2014-10-22 19:42:55 +01:00
Damien George 20f59e182e py: Make mp_const_empty_bytes globally available. 2014-10-21 21:02:56 +01:00
stijn 2fe4cf7761 Implement kwargs for builtin open() and _io.FileIO 
This makes open() and _io.FileIO() more CPython compliant.
The mode kwarg is fully iplemented.
The encoding kwarg is allowed but not implemented; mainly to allow
the tests to specify encoding for CPython, see #874

Damien George 21ca2d76a2 py: Partially fix viper multi-comparison; add test for it. 2014-10-19 19:00:51 +01:00
Paul Sokolovsky 1a55b6a787 unix, stmhal: Implement file.readinto() method. 
Also, usocket.readinto(). Known issue is that .readinto() should be available
only for binary files, but micropython uses single method table for both
binary and text files.

Damien George 090c9236e8 py: Fix compiling of nested while/for and exception handler. 
Addresses issue #912.
 2014-10-17 14:08:49 +00:00
Damien George 37ada236b3 py: Take gc_pool_start out of bss section, to reclaim 1st block of heap. 2014-10-16 21:50:39 +01:00
Paul Sokolovsky 923a8a8320 stream: Handle non-blocking errors in readline() properly. 
Just like they handled in other read*(). Note that behavior of readline()
in case there's no data when it's called is underspecified in Python lib
spec, implemented to behave as read() - return None.
 2014-10-16 12:22:52 +03:00
Paul Sokolovsky 0c7b26c0f8 stream: Return errno value as first arg of OSError exception. 
This is CPython-compatible convention established yet in acb13886fc.
 2014-10-16 02:58:52 +03:00
Paul Sokolovsky 067ae1269d objclosure: Fix printing of generator closures. 
The code previously assumed that only functions can be closed over.
 2014-10-16 00:14:01 +03:00
Damien George 9b0b373e5e py: Fix GC realloc issue, where memory chunks were never shrunk. 
Previously, a realloc to a smaller memory chunk size would not free the
unused blocks in the tail of the chunk.
 2014-10-15 18:24:47 +00:00
Damien George 4859edb95b py: Fix dummy definition of BEGIN/END_ATOMIC_SECTION. 2014-10-15 17:33:24 +00:00

Damien George 29f5682621 Merge pull request #904 from pfalcon/moduzlib 
Module "uzlib" - based on similarly named library
 2014-10-12 23:25:24 +01:00
Paul Sokolovsky 34162872b1 moduzlib: Integrate into the system. 2014-10-13 00:07:44 +03:00
Damien George c14a81662c py: Add module weak link support. 
With this patch a port can enable module weak link support and provide
a dict of qstr->module mapping.  This mapping is looked up only if an
import fails to find the requested module in the filesystem.

This allows to have the builtin module named, eg, usocket, and provide
a weak link of "socket" to the same module, but this weak link can be
overridden if a file by the name "socket.py" is found in the import
path.

Damien George 3c34d4140d py: Fix x86 viper code generation, mem8 <-> mem16 for load. 2014-10-12 16:10:25 +00:00
Damien George 91cfd414c0 py: Implement native load for viper. 
Viper can now do: ptr8(buf)[0], which loads a byte from a buffer using
machine instructions.

Paul Sokolovsky 1606607bd4 modure: Make sure that re1.5 compiled in only of modure itself is enabled. 
This is achieved by including re1.5 *.c files straight from modure.c .
 2014-10-12 03:40:20 +03:00
Paul Sokolovsky c71e045165 modure: Initial module, using re1.5 (which is based on re1 codebase).

Dave Hylands 3556e45711 Allow real memory errors (from locked gc) to be reported with traceback. 2014-10-07 08:07:49 -07:00
Damien George f32498fe04 py: Extra autodetect for little endianness using __LITTLE_ENDIAN__. 2014-10-06 16:09:31 +00:00
Damien George 9336ee320a py: Make mp_binary_set_val work on big endian machine. 2014-10-06 15:05:35 +00:00
Damien George fcdb239815 py: Make int.to_bytes work on big endian machine. 
Partly addresses issue #856.
 2014-10-06 13:45:34 +00:00
Damien George a9bcd51dc7 py: Try to autodetect machine endianness when not defined by port. 2014-10-06 13:44:59 +00:00
Damien George c4d0868df1 py: Implement proper context save/restore for eval/exec; factor code. 
This has benefits all round: code factoring for parse/compile/execute,
proper context save/restore for exec, allow to sepcify globals/locals
for eval, and reduced ROM usage by >100 bytes on stmhal and unix.

Also, the call to mp_parse_compile_execute is tail call optimised for
the import code, so it doesn't increase stack memory usage.
