Make all `PYTHON` env vars into `PYTHON3`

2020-01-12T05:37:54+00:00

make file contained a mix of references to `PYTHON` and `PYTHON3`, and did not build on a fresh install of Ubuntu (under Windows LXSS)

py.mk: Fix race condition building .mo files

2019-12-16T21:33:55+00:00

By having an order-only dependency on the directory itself, the directory is sure to be created before the rule to create a .mo file is. This fixes a low-freqency error on github actions such as > msgfmt: error while opening "build/genhdr/en_US.mo" for writing: No such file or directory

protocols: Allow them to be (optionally) type-safe

2019-12-04T15:29:57+00:00

Protocols are nice, but there is no way for C code to verify whether a type's "protocol" structure actually implements some particular protocol. As a result, you can pass an object that implements the "vfs" protocol to one that expects the "stream" protocol, and the opposite of awesomeness ensues. This patch adds an OPTIONAL (but enabled by default) protocol identifier as the first member of any protocol structure. This identifier is simply a unique QSTR chosen by the protocol designer and used by each protocol implementer. When checking for protocol support, instead of just checking whether the object's type has a non-NULL protocol field, use `mp_proto_get` which implements the protocol check when possible. The existing protocols are now named: protocol_framebuf protocol_i2c protocol_pin protocol_stream protocol_spi protocol_vfs (most of these are unused in CP and are just inherited from MP; vfs and stream are definitely used though) I did not find any crashing examples, but here's one to give a flavor of what is improved, using `micropython_coverage`. Before the change, the vfs "ioctl" protocol is invoked, and the result is not intelligible as json (but it could have resulted in a hard fault, potentially): >>> import uos, ujson >>> u = uos.VfsPosix('/tmp') >>> ujson.load(u) Traceback (most recent call last): File "", line 1, in ValueError: syntax error in JSON After the change, the vfs object is correctly detected as not supporting the stream protocol: >>> ujson.load(p) Traceback (most recent call last): File "", line 1, in OSError: stream operation not supported

Uncomment vm.c SUPEROPT (debugging typo); trim a few builds

2019-06-12T17:09:09+00:00

Turn off SUPEROPT on gc.c instead of trying to squueze inline limit so much; reorganize mpconfigboard.mk files

2019-06-12T15:08:22+00:00

Update py.mk

2019-04-05T19:39:44+00:00

Don't build machine class we don't use.

2019-01-15T01:30:01+00:00

Add support for adding release info into adafruit/circuitpython-org

2018-11-30T08:30:57+00:00

This also changes the build script to python with better output.
