suspect-devices/circuitpython/py/parse.c, branch v1.0-rc1 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.0-rc1 2014-04-10T14:27:31+00:00 py: Check explicitly for memory allocation failure in parser. 2014-04-10T14:27:31+00:00 Damien George damien.p.george@gmail.com 2014-04-10T14:27:31+00:00 urn:sha1:58ba4c3b4c12e9bf6b8731fd26e0c9cac527122f Previously, a failed malloc/realloc would throw an exception, which was not caught. I think it's better to keep the parser free from NLR (exception throwing), hence this patch. py: Clean up includes. 2014-03-17T09:43:40+00:00 xbe xbe@machine 2014-03-16T07:14:26+00:00 urn:sha1:efe34223945a5d27a7ae9445d0793d6330cd2411 Remove unnecessary includes. Add includes that improve portability. py: Implement bit-shift and not operations for mpz. 2014-03-01T19:50:50+00:00 Damien George damien.p.george@gmail.com 2014-03-01T19:50:50+00:00 urn:sha1:06201ff3d6d9485b2657fc9ac4aa8a306884322f Implement not, shl and shr in mpz library. Add function to create mpzs on the stack, used for memory efficiency when rhs is a small int. Factor out code to parse base-prefix of number into a dedicated function. parse: Refactor parse node encoding to support full range of small ints. 2014-02-22T14:39:45+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-02-22T14:39:45+00:00 urn:sha1:56e5ef203b01ac8dfb1cb46143f6f7c53237b79d Based on suggestion by @dpgeorge at https://github.com/micropython/micropython/pull/313 parse: Note that fact that parser's small ints are different than VM small int. 2014-02-21T01:27:09+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-02-21T00:04:32+00:00 urn:sha1:bbf0e2fe120f095ce09fcb7eb631c9fd04bd9760 Specifically, VM's small ints are 31 bit, while parser's only 28. There's already MP_OBJ_FITS_SMALL_INT(), so, for clarity, rename MP_FIT_SMALL_INT() to MP_PARSE_FITS_SMALL_INT(). Implement proper exception type hierarchy. 2014-02-15T16:10:44+00:00 Damien George damien.p.george@gmail.com 2014-02-15T16:10:44+00:00 urn:sha1:c5966128c7c8a768f6726f299d85d5daef6bed48 Each built-in exception is now a type, with base type BaseException. C exceptions are created by passing a pointer to the exception type to make an instance of. When raising an exception from the VM, an instance is created automatically if an exception type is raised (as opposed to an exception instance). Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper. Handling of parse error changed to match new exceptions. mp_const_type renamed to mp_type_type for consistency. Replace global "static" -> "STATIC", to allow "analysis builds". Part 2. 2014-02-12T16:31:30+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-02-12T16:31:30+00:00 urn:sha1:520e2f58a559c356ea540a5da4e9a585649aecc6 py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int. 2014-01-29T18:58:52+00:00 Damien George damien.p.george@gmail.com 2014-01-29T18:58:52+00:00 urn:sha1:08d075592f3fa958ac3f24e176bee5ab56e78f49 LOAD_METHOD bug was: emitbc did not correctly calculate the amount of stack usage for a LOAD_METHOD operation. small int bug was: int was being used to pass small ints, when it should have been machine_int_t. Implement mp_parse_node_free; print properly repr(string). 2014-01-25T13:51:19+00:00 Damien George damien.p.george@gmail.com 2014-01-25T13:51:19+00:00 urn:sha1:b829b5caecd1ba4fbc30e03978776d2c868dd67b Add parse_node_free_struct() and use it to free parse tree after compilation. 2014-01-25T00:11:59+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-01-24T22:56:19+00:00 urn:sha1:aee2ba70de774f954a793efb73e72faaf4e6524d TODO: Check lexer/parse/compile error path for leaks too.
