Default to just calling python since that is most commonly available: the
official installer or zipfiles from python.org, anaconda, nupkg all result
in python being available but not python3. In other words: the default
used so far is wrong. Note that os.name is 'posix' when running the python
version which comes with Cygwin or MSys2 so they are not affected by this.
However of all possible ways to get Python on Windows, only Cygwin provides
no python command so update the default way for running tests in the
README.

Make the instructions more complete by documenting all needed steps for
starting from scratch. Also add a section for MSYS2 since the Travis build
uses it as well and it's a good alternative for Cygwin. Remove the mingw32
reference since it's not readily available anymore in most Linux distros
nor compiles successfully.

Alter the build flags as needed to support freezing modules with a
manifest. This makes freezing works just like it does for e.g. the unix
port.
|
|
Support freezing modules via manifest.py for consistency with the other
ports. In essence this comes down to calling makemanifest.py and adding
the resulting .c file to the build. Note the file with preprocessed qstrs
has been renamed to match what makemanifest.py expects and which is also
the name all other ports use.
|
|
Adds a new compile-time option MICROPY_PY_MATH_POW_FIX_NAN for use with
toolchains that don't handle pow-of-NaN correctly.
|
|
By setting MICROPY_EPOCH_IS_1970 a port can opt to use 1970/1/1 as the
Epoch for timestamps returned by stat(). And this setting is enabled on
the unix and windows ports because that's what they use.

Add configuration which otherwise has to be set via the UI so the file is
more self-contained, and remove configuration which is not needed because
it's the same as the default. The major change here is that for a while
now Appveyor has been using Visual Studio 2015 by default while we still
want to support 2013.
|
|
Older implementations deal with infinity/negative zero incorrectly. This
commit adds generic fixes that can be enabled by any port that needs them,
along with new tests cases.

No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port. This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.
Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.
The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.

Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.
|
|
Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out
implicit floating point conversions, and add extra Travis builds using
MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found
previously. For the unix port -Wsign-comparison is added as well but only
there since only clang supports this but gcc doesn't.
|
|
These are found when building with -Wfloat-conversion.
|
|
|
|
Using new options enabled in the uncrustify configuration.
|
|
|
|
This replaces 0 and 1 with STDIN_FILENO and STDOUT_FILENO to make the
intention of the code clearer.
|
|
This removes the port-specific definition of MP_PLAT_PRINT_STRN on the
windows port, so that the default mp_hal_stdout_tx_strn_cooked() is always
used. This fixes releasing the GIL during the call to write() (this was
missed in bc3499f0103abcae39ad048bb42a518a665b8497).
Also, mp_hal_dupterm_tx_strn() was defined but never used anywhere so it is
safe to delete it.
|
|
Fix missing mkdir and gettimeofday declarations, then silence msvc-specific
compiler warning C4996: 'The POSIX name for this item is deprecated'.
|
|
The implementation in extmod/vfs_posix_file.c is now equivalent to that in
ports/unix/file.c, so remove the latter and use the former instead.
|
|
This is run with uncrustify 0.70.1, and black 19.10b0.
|
|
The default value for MICROPYPATH used in unix/main.c is
"~/.micropython/lib:/usr/lib/micropython" which has 2 problems when used in
the Windows port:
- it has a ':' as path separator but the port uses ';' so the entire string
is effectively discarded since it gets interpreted as a single path which
doesn't exist
- /usr/lib/micropython is not a valid path in a standard Windows
environment
Override the value with a suitable default.
|
|
The mp_keyboard_interrupt() function does exactly what is needed here, and
using it gets ctrl-C working when MICROPY_ENABLE_SCHEDULER is enabled on
these ports (and MICROPY_ASYNC_KBD_INTR is disabled).
|
|
This releases the GIL during syscalls that could block.
|
|
Translate common Ctrl-Left/Right/Delete/Backspace to the EMACS-style
sequences (i.e. Alt key based) for forward-word, backward-word, forwad-kill
and backward-kill. Requires MICROPY_REPL_EMACS_WORDS_MOVE to be defined so
the readline implementation interprets these.
|

|
Add the project file to the mpy-cross directory, which is also where the
executable ends up, and change the Appveyor settings to build mpy-cross
with both msvc and mingw-w64 and verify this all works by running tests
with --via-mpy.
|
|
If this is not set it might default to calls to open() to use text mode
which is usually not wanted, and even wrong and leading to incorrect
results when loading binary .mpy files.
This also means that text files written and read will not have line-ending
translation from \n to \r\n and vice-versa anymore. This shouldn't be much
of a problem though since most tools dealing with text files adapt
automatically to any of the 2 formats.
|
|
Reserve sources.props for listing just the MicroPython core and extmod
files, similar to how py.mk lists port-independent source files. This
allows reusing the source list, for instance for building mpy-cross. The
sources for building the executable itself are listed in the corresponding
project file, similar to how the other ports specify the source files in
their Makefile.
|
|
Append to PyIncDirs, used to define include directories specific to
MicroPython, instead of just overwriting it so project files importing this
file can define additional directories. And allow defining the target
directory for the executable instead of hardcoding it to the windows
directory. Main reason for this change is that it will allow building
mpy-cross with msvc.
|
|
We want the .vcxproj to be just a container with the minimum content for
making it work as a project file for Visual Studio and MSBuild, whereas the
actual build options and actions get placed in separate reusable files.
This was roughly the case already except some compiler options were
overlooked; fix this here: we'll need those common options when adding a
project file for building mpy-cross.
|
|
These were probably added to detect more qstrs but as long as the
micropython executable itself doesn't use the same build options the qstrs
would be unused anyway. Furthermore these definitions are for internal use
and get enabled when corresponding MICROPY_EMIT_XXX are defined, in which
case the compiler would warn about symbol redefinitions since they'd be
defined both here and in the source.

To be consistent with the unix port.
|
|
This is consistent with the other ports and helps catching problems early.
|
|
As per PEP 485, this function appeared in for Python 3.5. Configured via
MICROPY_PY_MATH_ISCLOSE which is disabled by default, but enabled for the
ports which already have MICROPY_PY_MATH_SPECIAL_FUNCTIONS enabled.
|
|
The C++ standard forbids redefining keywords, like inline and alignof, so
guard these definitions to avoid that, allowing to include the MicroPython
headers by C++ code.
|
|
|
|
This enables going back to previous wrapped lines using backspace or left
arrow: instead of just sticking to the beginning of a line, the cursor will
move a line up.
|
|
During make, makemoduledefs.py parses the current builds c files for
MP_REGISTER_MODULE(module_name, obj_module, enabled_define)
These are used to generate a header with the required entries for
"mp_rom_map_elem_t mp_builtin_module_table[]" in py/objmodule.c
|
|
GNU readline support for the unix port was removed in
acaa30b6046d449f5f58a8f02c83459702759df7 and in
5e83a75c78dc8c370b25e7ee669295854ea45130, so it's also no longer supported
in the windows port.
|
|
Add some more POSIX compatibility by adding a d_type field to the
dirent structure and defining corresponding macros so listdir_next
in the unix' port modos.c can use it, end result being uos.ilistdir
now reports the file type.
|
|
|
|
Use overrideable properties instead of hardcoding the use of the
default cl executable used by msvc toolsets. This allows using
arbitrary compiler commands for qstr header generation.
The CLToolExe and CLToolPath properties are used because they are,
even though absent from any official documentation, the de-facto
standard as used by the msvc toolsets themselves.
|
|
This patch in effect renames MICROPY_DEBUG_PRINTER_DEST to
MICROPY_DEBUG_PRINTER, moving its default definition from
lib/utils/printf.c to py/mpconfig.h to make it official and documented, and
makes this macro a pointer rather than the actual mp_print_t struct. This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.
Ports are updated to use the new macro name.
|
|
Printing debugging info by defining MICROPY_DEBUG_VERBOSE expects
a definition of the DEBUG_printf function which is readily available
in printf.c so include that file in the build. Before this patch
one would have to manually provide such definition which is tedious.
For the msvc port disable MICROPY_USE_INTERNAL_PRINTF though: the
linker provides no (easy) way to replace printf with the custom
version as defined in printf.c.
