MicroPython - a lean and efficient Python implementation for
microcontrollers and constrained systems.

Hi Buildroot,
Thought you might be interested in mircopython a minimal python 3
implementation. It's designed for micro controllers but is also well suited
to other general purpose embedded CPUs.
Cheers,
Chris

The website says:
"Micro Python is a lean and fast implementation of the Python 3
programming language that is optimised to run on a microcontroller."
So, why don't we use that comment instead? It also specifies the Python
version which is important.
More comments below. Please scroll down.

Same here, I would use the same exact command you can find in
mycropython's website.

A comment about why this is necessary for powerpc would be good, IMHO.

micropython calls pkg-config in order to obtain the libraries and cflags
for libffi:
ifeq ($(MICROPY_PY_FFI),1)
LIBFFI_LDFLAGS_MOD := $(shell pkg-config --libs libffi)
LIBFFI_CFLAGS_MOD := $(shell pkg-config --cflags libffi)
CFLAGS_MOD += $(LIBFFI_CFLAGS_MOD) -DMICROPY_PY_FFI=1
So please, add host-pkgconf to MICROPYTHON_DEPENDENCIES. Otherwise it
will fail to compile with an error like this one:
LINK micropython
build/modffi.o: In function `ffifunc_call':
modffi.c:(.text+0x24c): undefined reference to `ffi_call'
modffi.c:(.text+0x260): undefined reference to `ffi_call'
build/modffi.o: In function `mod_ffi_callback':
modffi.c:(.text+0x7b0): undefined reference to `ffi_closure_alloc'
... and many more

Please add $(TARGET_MAKE_ENV) before $(MAKE). You need that in order to
Buildroot set the PATH variable so the pkg-config executable and the
libffi.pc file can be found.

Vincent.

OK thanks. Will look at these comments and the ones from the other
mail. I was using qemu_x86_defconfig for testing so it probably picked
up things from my host environment.

Some quick questions that come to mind:
* What happens if we have Micropython installed next to the regular
Python 2 or Python 3 interpreters / standard library on the same
system? Do they conflict or not?
* What about all the Python external modules (package/python-*/) we
have in Buildroot? Do they work with Micropython?

Nitpick: use the standard header for all packages. You lack an empty
line before and after the package name. See all other Buildroot
packages. Ditto for the micropython package.

You should define MICROPYTHON_LIB_LICENSE as well.

It shouldn't conflict as micropython installs the library files under
/usr/lib/micropython/ directory. And the installed binaries are
/usr/local/bin/{pip-}micropython. Perhaps this should be changed to
install them in /usr instead of /usr/local.

Vincent.

The local part seems hard-coded to me. But we could always sed it on
the way through.

It's not normal for Buildroot systems to have stuff in /usr/local.
Perhaps you could write a patch for micropython to make this
configurable and submit the patch upstream?
Thanks,

Adding PREFIX=$(TARGET_DIR)/usr to MICROPYTHON_INSTALL_TARGET_CMDS
works for me:
$ ls output/target/usr/bin/
micropython pip-micropython

They're installed in with different executable names and library paths
so they should co-exist happily.

Probably depends on the module, but I assume the answer is mostly no.
Some of the "standard" libraries in micropython-lib are stubs to quote
the readme: "micropython-lib is a highly experimental community
project". Getting into buildroot is one way of helping them to move
out of "experimental" status.

That's an interesting problem. It's actually multiple licenses
(depending on the source of the library) so nothing in the "normal"[1]
list fits. I could say "various" or enumerate the ones I can identify
but it would be hard to be accurate.

Good.

Ok. Anyway, the Python external modules are installed
in /usr/lib/python<version>/, so micropython will not see them. So
we're safe if someone enables both micropython, python 2 and a bunch of
python external modules: python 2 will allow to use the python external
modules, and micropython will live its own life without providing
access to the python external modules.

Sure, makes sense.

Isn't it a bit problematic for an open-source project to not have a
clear license (or list of licenses) ? It basically means that you can't
safely redistribute it.
I believe listing all the licenses is the proper course of action here.
Something like:
<foo>_LICENSE = MIT (this, that), BSD-2c (foo, bar)
Thanks!

Hi Buildroot,
Thought you might be interested in mircopython a minimal python 3
implementation. It's designed for micro controllers but is also well suited
to other general purpose embedded CPUs.
Cheers,
Chris
Changes since v1:
- Add dependency on host-pkgconf.
- Use $(TARGET_MAKE_ENV) in make invocation for micropython
(micropython-lib doesn't need it because it doesn't use anything setup by
it).
- Override PREFIX to install to /usr/bin instead of /usr/local/bin
- Update/add some comments.

As Thomas suggested, improve that by listing the licenses. According to
the LICENSE file, everything is MIT unless the setup.py of each module
says something different, so I have done a quick check:
$ find micropython-lib-v0.5/ -type f -name "setup.py" -exec grep license
{} \; | sort -u
license='MIT',
license='Python',
So I think it would be enough by just having:
MICROPYTHON_LIB_LICENSE = Python (some modules), MIT (everything else)
Thomas, what do you think?

It will not harm to add $(TARGET_MAKE_ENV) before $(MAKE) here as well.

This comment, are you trying to keep the lines 80 characters long? In
that case, you can put "don't" in the first line.

I haven't checked micropython source code myself, but what you propose
looks sensible, to the exception that "Python" isn't a license. The
license of Python is "Python software foundation license v2".

I'll send a v3 mopping up the additional comments at some point.
One issue I am facing is that the build process for micropython ties
into git to generate it's version string which works when built from a
clone of the micropython git repo. But when run via buildroot it ends
up getting the version based on the buildroot git repo so the version
number displayed is 2015.10-... instead of 1.4.5. I'll do some
investigation to see if I can override the automatic logic but I was
wondering if there are any other packages with similar problems and
how they were addressed.

Changes since v1:
- Add dependency on host-pkgconf.
- Use $(TARGET_MAKE_ENV) in make invocation for micropython
(micropython-lib doesn't need it because it doesn't use anything setup by
it).
- Override PREFIX to install to /usr/bin instead of /usr/local/bin
- Update/add some comments.
Changes since v2:
- Use $(TARGET_MAKE_ENV) in micropython-lib for consistency
- Update LICENSE for micropython-lib (thanks to Vincent for the shell
snippet that saved me having to check them manually).
- Add patch to take the version number from the package instead of from the
buildroot git repository.

It starts to look almost good, there are still a few things to adjust.

Could you split that up into two patches, one for micropython, and one
for micropython-libs (in that order in the patch series) ?

Is this really the correct value for PREFIX ? I haven't checked myself,
but PREFIX=$(TARGET_DIR)/usr would look more traditional.

All patches need a description + Signed-off-by line. See
http://git.buildroot.net/buildroot/tree/package/python/100-optional-test-modules.patch
for example.

If you select libffi, then you need to replicate the dependencies of
libffi, so:
depends on BR2_TOOLCHAIN_HAS_THREADS

And:
comment "micropython needs a toolchain w/ thread"
depends on !BR2_TOOLCHAIN_HAS_THREADS

It seems like this is going to do the build and installation in the
<pkg>_INSTALL_TARGET_CMDS, which isn't nice. I've done a quick test,
and the following seems to work:
define MICROPYTHON_BUILD_CMDS
$(TARGET_MAKE_ENV) $(MAKE) -C $(@D)/unix \
CROSS_COMPILE=$(TARGET_CROSS) \
CFLAGS_EXTRA=$(MICROPYTHON_CFLAGS)
endef
define MICROPYTHON_INSTALL_TARGET_CMDS
$(TARGET_MAKE_ENV) $(MAKE) -C $(@D)/unix \
DESTDIR=$(TARGET_DIR) \
PREFIX=$(TARGET_DIR)/usr \
install
endef
Which is much more in line with Buildroot standards.
Thanks!
Thomas

Yes it's correct for the way the micropython-lib Makefile[1] is written.

Thought you might be interested in mircopython a minimal python 3
implementation. It's designed for micro controllers but is also well suited
to other general purpose embedded CPUs.
Cheers,
Chris
Changes since v1:
- Add dependency on host-pkgconf.
- Use $(TARGET_MAKE_ENV) in make invocation for micropython
(micropython-lib doesn't need it because it doesn't use anything setup by
it).
- Override PREFIX to install to /usr/bin instead of /usr/local/bin
- Update/add some comments.
Changes since v2:
- Use $(TARGET_MAKE_ENV) in micropython-lib for consistency
- Update LICENSE for micropython-lib (thanks to Vincent for the shell
snippet that saved me having to check them manually).
- Add patch to take the version number from the package instead of from the
buildroot git repository.
Changes since v3:
- Split into 2 patches
- Separate build and install steps for micropython
- Minor style fixes

This is something the maintainer can amend for you, I guess, so you
don't need to send another patch.

There are no binary files to check if it was build for the right

There are a number of build failures caused by Micropython in the
autobuilders:
* On MIPS64
http://autobuild.buildroot.org/results/99a/99a610c72877fef53d93e1a923bd5c71b3376618/build-end.log
* On Xtensa
http://autobuild.buildroot.org/results/670/670907760d6b3e7eb46b433647b392cec3bafdcd/build-end.log
* On SH4A
http://autobuild.buildroot.org/results/f5a/f5a2c563b8bdab9e345960a5b92d31f3f92dba00/build-end.log
See http://autobuild.buildroot.org/?reason=micropython-v1.4.5 for the
complete list of build failures.
If you could look into these, it would be helpful.
Thanks!

Xtensa and SH4A look like they need MICROPY_GCREGS_SETJMP I'll send a
patch for them shortly. The MIPS64 one looks different so might need
some investigation.

These architectures don't have explicit exception handling support in
micropython but can use the setjmp fallback behaviour instead.

as the build error says, a right shift is being performed in the
py/objint_mpz.c file, and the offending one is at line #54:
MP_SSIZE_MAX >> MPZ_DIG_SIZE * 4
in MIPS64 n64 the MP_SSIZE_MAX is 64-bit wide and the value of
MPZ_DIG_SIZE 16, so MPZ_DIG_SIZE * 4 is 64. That shift causes a warning
because its trying to shift 64 bits of a 64-bit variable:
py/objint_mpz.c:54:5: error: right shift count >= width of type [-Werror]
MIPS32 and MIPS64 n32 are fine because MP_SSIZE_MAX is 32-bit wide and
the #if clauses in the py/objint_mpz.c protect that to happen.
Look at this test for MIPS32:
$ mips-linux-gnu-gcc -mips32r2 -EB ssize_t.c -o ssize_t
$ qemu-mips ssize_t
MP_SSIZE_MAX: 32 bits
MPZ_DIG_SIZE: 16
right-shifting 0 bits
right-shifting 16 bits
And now look at the same test for MIPS64 n64:
$ mips-linux-gnu-gcc -mips64r2 -mabi=64 -EB ssize_t.c -o ssize_t
ssize_t.c: In function 'main':
ssize_t.c:24:2: warning: right shift count >= width of type
(MP_SSIZE_MAX >> MPZ_DIG_SIZE * 4) & DIG_MASK;
^
$ qemu-mips64 ssize_t
MP_SSIZE_MAX: 64 bits
MPZ_DIG_SIZE: 16
right-shifting 0 bits
right-shifting 16 bits
right-shifting 32 bits
right-shifting 48 bits
right-shifting 64 bits
I don't know what's the purpose of the code in py/objint_mpz.c and I
don't know if they really want to do a 64-bit shift of a 64-bit
variable. But the thing is that since it's compiled with the -Werror
flag, that warning makes the compilation to fail.
If they really want to do such a shift, then they should remove the
-Werror. But if they don't want to do such a shift, then more #if
clauses are needed in order to prevent that to happen. Perhaps you could
talk with upstream about this.
Regards,
Vincent.

I raised an issue [1]. But in the meantime I think I've found the
right setting to pass for a 64 bit target. Patch to follow.

From the micropython source:
This mpz module implements arbitrary precision integers.
The storage for each digit is defined by mpz_dig_t. The actual number
of bits in mpz_dig_t that are used is defined by MPZ_DIG_SIZE. The
machine must also provide a type that is twice as wide as mpz_dig_t,
in both signed and unsigned versions
MPZ_DIG_SIZE can be between 4 and 8*sizeof(mpz_dig_t), but it makes
most sense to have it as large as possible.
Micropython detects x86_64 targets and sets MPZ_DIG_SIZE appropriately
but for other 64-bit targets we need to explicitly pass
-DMPZ_DIG_SIZE=32 in CFLAGS.

you have to take into account that MIPS64 n32 is a 64-bit target as
well, but it has a MP_SSIZE_MAX of 32-bit. So, if you set MPZ_DIG_SIZE
to 32 for all 64-bit arches, then you will see the same failure for the
when building for MIPS64 n32.
I suggest you to do modify the "ifeq" like this:
# MIPS64 n32 is a 64-bit arch, but it has a 32-bit wide SSIZE_MAX which
# means we still need the default MPZ_DIG_SIZE of 16.
ifeq ($(BR2_ARCH_IS_64)$(BR2_MIPS_NABI32),y)

Vincent.

I'll take a look. The remote machine I was doing my buildroot hacking
on has gone AWOL so it may take a while for me to get it back up and
running (there was a planned server outage so I suspect it's trying to
access some non-existent mounts).
When I asked upstream there was a thought that this commit[1] might
fix the issue. So I'll try adding that as a patch first.
