suspect-devices/circuitpython/py/objexcept.c, branch v1.3.5 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.3.5 2014-10-25T22:37:57+00:00 py: Add mp_pending_exception global variable, for VM soft interrupt. 2014-10-25T22:37:57+00:00 Damien George damien.p.george@gmail.com 2014-10-25T17:19:55+00:00 urn:sha1:124df6f8d07b53542b6960dbeea9b63bff469a67 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). py: Remove unused and unneeded SystemError exception. 2014-10-22T18:42:55+00:00 Damien George damien.p.george@gmail.com 2014-10-22T18:42:55+00:00 urn:sha1:e7a478204a984f9f79a99700375d961be6d28a96 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. py: Fix dummy definition of BEGIN/END_ATOMIC_SECTION. 2014-10-15T17:33:24+00:00 Damien George damien.p.george@gmail.com 2014-10-15T17:33:24+00:00 urn:sha1:4859edb95b53313b140318ee8674ec617c8c7566 py: Remove IOError since it's deprecated; use OSError instead. 2014-09-30T13:59:30+00:00 Damien George damien.p.george@gmail.com 2014-09-30T13:59:30+00:00 urn:sha1:8b03d944e2ae64f7987116ff342fbd1cc3b97b71 In CPython IOError (and EnvironmentError) is deprecated and aliased to OSError. All modules that used to raise IOError now raise OSError (or a derived exception). In Micro Python we never used IOError (except 1 place, incorrectly) and so don't need to keep it. See http://legacy.python.org/dev/peps/pep-3151/ for background. py: Tidy up exception matching; allow matching of tuple of exceptions. 2014-09-25T14:49:26+00:00 Damien George damien.p.george@gmail.com 2014-09-24T13:05:40+00:00 urn:sha1:4bcd04bcaddeeb53779f2c067a4d1b533c888f9d Addresses issue #864. py: Change all uint to mp_uint_t in obj.h. 2014-08-30T13:19:41+00:00 Damien George damien.p.george@gmail.com 2014-08-30T13:19:41+00:00 urn:sha1:d182b98a37bde34c06ae705624da03cf381eb4dc Part of code cleanup, working towards resolving issue #50. py: Make tuple and list use mp_int_t/mp_uint_t. 2014-08-30T13:04:14+00:00 Damien George damien.p.george@gmail.com 2014-08-30T13:04:14+00:00 urn:sha1:9c4cbe2ac0ae4c51270f21ba9c974dd24f6b9d55 Part of code cleanup, to resolve issue #50. Change some parts of the core API to use mp_uint_t instead of uint/int. 2014-08-29T23:35:11+00:00 Damien George damien.p.george@gmail.com 2014-08-29T23:35:11+00:00 urn:sha1:ecc88e949ca5e307d22da4605a40d39ea2df9e3b Addressing issue #50, still some way to go yet. stmhal: Make enable_irq and disable_irq inline functions. 2014-08-25T12:24:33+00:00 Damien George damien.p.george@gmail.com 2014-08-25T12:24:33+00:00 urn:sha1:e5cbb70328239e58c820938eccd51f3c735fc312 These functions are generally 1 machine instruction, and are used in critical code, so makes sense to have them inline. Also leave these functions uninverted (ie 0 means enable, 1 means disable) and provide macro constants if you really need to distinguish the states. This makes for smaller code as well (combined with inlining). Applied to teensy port as well. Add save/restore_irq 2014-08-25T11:22:11+00:00 Dave Hylands dhylands@gmail.com 2014-08-24T19:21:12+00:00 urn:sha1:9480138f0c917b2400991066e94636f7d8076a4c Factored irq functions into a separate file.
