This fixes errors like these ones:
modffi.c: In function 'return_ffi_value':
modffi.c:143:29: error: cast to pointer from integer of different size
[-Werror=int-to-pointer-cast]
const char *s = (const char *)val;
^
modffi.c:162:20: error: cast to pointer from integer of different size
[-Werror=int-to-pointer-cast]
return (mp_obj_t)val;
^
modffi.c: In function 'ffifunc_call':
modffi.c:358:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
values[i] = (ffi_arg)a;
^
modffi.c:373:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
values[i] = (ffi_arg)s;
^
modffi.c:381:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
values[i] = (ffi_arg)bufinfo.buf;
^
modffi.c:384:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
values[i] = (ffi_arg)p->func;
^
These errors can be highlighted when building micropython from MIPS64
n32 because ffi_arg is 64-bit wide and the pointers on MIPS64 n32 are
32-bit wide, so it's trying to case an integer to a pointer (or
vice-versa) of a different size. We should cast first the pointer (or the
integer) to a pointer sized integer (intptr_t) to fix that problem.

Follow the same format as other ports using the macro to include
the HAL header.

So far, no signature check is done (TODO).

Useful to load native method libraries not loaded by VM (as happens on
Android).

This includes Android Dalvik VM for example.
Example usage:
import jni
System = jni.cls("java/lang/System")
System.out.println("Hello, Java!")

This may be a bit confusing, as ENOENT is often rendered as "No such
file or directory", but any other code would be only more confusing.

Linking against local libffi (and other libs in future) is triggered by
"make MICROPY_STANDALONE=1". Before that, dependent libs should be built
with "make deplibs".

Indeed, this flag efectively selects architecture target, and must
consistently apply to all compiles and links, including 3rd-party
libraries, unlike CFLAGS, which have MicroPython-specific setting.

inet_pton supports both ipv4 and ipv6 addresses. Interface is also extensible
for other address families, but underlying libc inet_pton() function isn't
really extensible (e.g., it doesn't return length of binary address, i.e. it's
really hardcoded to AF_INET and AF_INET6). But anyway, on Python side, we could
extend it to support other addresses.

Required to implement UDP servers.
|
|
sendto() turns out to be mandatory function to work with UDP. It may seem
that connect(addr) + send() would achieve the same effect, but what connect()
appears to do is to set source address filter on a socket to its argument.
Then everything falls apart: socket sends to a broad-/multi-cast address,
but reply is sent from real peer address, which doesn't match filter set
by connect(), so local socket never sees a reply.
|
|
Treating it as signed lead to buffer overflow for ports >= 32768.
|
|
This usually allows to get just a single address entry.
|
|
This requires root access. And on recent Linux kernels, with
CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in
/proc/iomem can be accessed. The above compiled-time option can be
however overriden with boot-time option "iomem=relaxed".
This also removed separate read/write paths - there unlikely would
be a case when they're different.

To comply with Python semantics.

Previous to this patch a call such as list.append(1, 2) would lead to a
seg fault. This is because list.append is a builtin method and the first
argument to such methods is always assumed to have the correct type.
Now, when a builtin method is extracted like this it is wrapped in a
checker object which checks the the type of the first argument before
calling the builtin function.
This feature is contrelled by MICROPY_BUILTIN_METHOD_CHECK_SELF_ARG and
is enabled by default.

MicroPython doesn't come with standard library included, so it is important
to be able to easily install needed package in a seamless manner. Bundling
package manager (upip) inside an executable solves this issue.
upip is bundled only with standard executable, not "minimal" or "fast"
builds.
|
|
This assures the terminal prints it's prompt on a fresh line instead of
appending it to the uPy prompt after exit.
|
|
After switching to builtin readline support, "minimal" no longer builds, and
minimal doesn't really need readline support.
|
|
Using MICROPY_PY_SYS_PATH_DEFAULT macro define. A usecase is building a
distribution package, which should not have user home path by default in
sys.path. In such case, MICROPY_PY_SYS_PATH_DEFAULT can be defined on
make command-line (using CFLAGS_EXTRA).
|
|
|
|
This gets uPy readline working with unix port, with tab completion and
history. GNU readline is still supported, configure using
MICROPY_USE_READLINE variable.

This reverts commit 8fbabab1a80efa8b9c0654f63b2157d8f8299955. Turned to
cause problems on MacOSX.
