WIP: after merge; before testing 2018-07-11T20:45:30+00:00 Dan Halbert halbert@halwitz.org 2018-07-11T20:45:30+00:00 urn:sha1:7c219600a246d8956d0b23ea3f5d125a820e6b6a py/objstr: In find/rfind, don't crash when end < start. 2018-04-05T06:14:17+00:00 Jeff Epler jepler@gmail.com 2018-04-01T02:27:56+00:00 urn:sha1:d6cf5c674952d5ae3463d9b580dac6559576deac py/objstr: Don't crash when end < start 2018-04-01T03:17:11+00:00 Jeff Epler jepler@gmail.com 2018-04-01T02:27:56+00:00 urn:sha1:0041df0c6b493458000d7e815e094995cfbc8043 .. and add testcases for the same. (crash found by afl-fuzz) py/runtime: Check that keys in dicts passed as ** args are strings. 2018-03-30T00:13:32+00:00 Damien George damien.p.george@gmail.com 2018-03-30T00:09:00+00:00 urn:sha1:32807881954f106b9735de74fe984062a0815b81 Prior to this patch the code would crash if a key in a ** dict was anything other than a str or qstr. This is because mp_setup_code_state() assumes that keys in kwargs are qstrs (for efficiency). Thanks to @jepler for finding the bug. py/objstr: Remove unnecessary check for positive splits variable. 2018-02-20T08:19:02+00:00 Damien George damien.p.george@gmail.com 2018-02-20T08:19:02+00:00 urn:sha1:8769049e935a89daa51883755457a083a5589d4e At this point in the code the variable "splits" is guaranteed to be positive due to the check for "splits == 0" above it. py/objstr: Protect against creating bytes(n) with n negative. 2018-02-19T05:25:30+00:00 Damien George damien.p.george@gmail.com 2018-02-19T05:25:30+00:00 urn:sha1:4e469085c192017c5244bbc115bac90f4bb667cb Prior to this patch uPy (on a 32-bit arch) would have severe issues when calling bytes(-1): such a call would call vstr_init_len(vstr, -1) which would then +1 on the len and call vstr_init(vstr, 0), which would then round this up and allocate a small amount of memory for the vstr. The bytes constructor would then attempt to zero out all this memory, thinking it had allocated 2^32-1 bytes. py/unicode: Clean up utf8 funcs and provide non-utf8 inline versions. 2018-02-14T07:19:22+00:00 Damien George damien.p.george@gmail.com 2018-02-14T07:19:22+00:00 urn:sha1:19aee9438a7a8cf8539536dab5147aedb6b16bb3 This patch provides inline versions of the utf8 helper functions for the case when unicode is disabled (MICROPY_PY_BUILTINS_STR_UNICODE set to 0). This saves code size. The unichar_charlen function is also renamed to utf8_charlen to match the other utf8 helper functions, and the signature of this function is adjusted for consistency (const char* -> const byte*, mp_uint_t -> size_t). py: Annotate func defs with NORETURN when their corresp decls have it. 2017-11-29T04:43:40+00:00 Damien George damien.p.george@gmail.com 2017-11-29T04:43:40+00:00 urn:sha1:3990a52c0f071a7a48cc276f30785930f31eed39 py/runtime: Add MP_BINARY_OP_CONTAINS as reverse of MP_BINARY_OP_IN. 2017-11-24T03:48:23+00:00 Damien George damien.p.george@gmail.com 2017-11-24T02:04:24+00:00 urn:sha1:5e34a113eaaf736fb4f703a3ee0892e1705d0a63 Before this patch MP_BINARY_OP_IN had two meanings: coming from bytecode it meant that the args needed to be swapped, but coming from within the runtime meant that the args were already in the correct order. This lead to some confusion in the code and comments stating how args were reversed. It also lead to 2 bugs: 1) containment for a subclass of a native type didn't work; 2) the expression "{True} in True" would illegally succeed and return True. In both of these cases it was because the args to MP_BINARY_OP_IN ended up being reversed twice. To fix these things this patch introduces MP_BINARY_OP_CONTAINS which corresponds exactly to the __contains__ special method, and this is the operator that built-in types should implement. MP_BINARY_OP_IN is now only emitted by the compiler and is converted to MP_BINARY_OP_CONTAINS by swapping the arguments.
