Now consistently uses the EOL processing ("\r" and "\r\n" convert to "\n")
and EOF processing (ensure "\n" before EOF) provided by next_char().
In particular the lexer can now correctly handle input that starts with CR.
Prior to this patch only 'q' and 'Q' type arrays could store big-int
values. With this patch any big int that is stored to an array is handled
by the big-int implementation, regardless of the typecode of the array.
This allows arrays to work with all type sizes on all architectures.
This will lead to crash like:
FATAL: uncaught NLR 80a5420
On x86_32, the minimum heap size is smaller, but not 2 times, so just
use value which works for x86_64.
The GC was deleting memory that was in use because its scan of the
stack missed the very top. Switching to _estack fixes this by relying
on the location from the linker.
Fixes#124
This patch allows mounting of VFS objects right at the root directory, eg
os.mount(vfs, '/'). It still allows VFS's to be mounted at a path within
the root, eg os.mount(vfs, '/flash'), and such mount points will override
any paths within a VFS that is mounted at the root.
Also replace use of PINMUX_DEFAULT with PINMUX_UNUSED to prevent any
accidental pin changes. This caused user SPI to break internal SPI
flash on the Feather M0 Express.
Fixes#100
Versions prior to v14.0 have a bug in parsing item functions when used
within a condition: https://github.com/Microsoft/msbuild/issues/368.
Since commit [db9c2e3] this results in an error when building MicroPython
with for example VS2013.
Fix this by creating an intermediate property.
fmode.c should only be included for builds targetting 'pure' windows, i.e.
msvc or mingw builds but not when using msys or cygwin's gcc (see #2298).
Just checking if the OS is windows and UNAME doesn't have msys stil leaves
the gate open for builds with cygwin's gcc since UNAME there is e.g.
CYGWIN_NT-6.1-WOW.
Fix this by checking for 'mingw' explicitly in the compiler version; both
gcc and clang have the -dumpmachine flag so the check should be ok for
all platforms.
The with semantics of this function is close to
pkg_resources.resource_stream() function from setuptools, which
is the canonical way to access non-source files belonging to a package
(resources), regardless of what medium the package uses (e.g. individual
source files vs zip archive). In the case of MicroPython, this function
allows to access resources which are frozen into the executable, besides
accessing resources in the file system.
This is initial stage of the implementation, which actually doesn't
implement "package" part of the semantics, just accesses frozen resources
from "root", or filesystem resource - from current dir.
Do not raise SIGPIPE, instead return EPIPE. Otherwise, e.g. writing
to peer-closed socket will lead to sudden termination of MicroPython
process. SIGPIPE is particularly nasty, because unix shell doesn't
print anything for it, so the above looks like completely sudden and
silent termination for unknown reason. Ignoring SIGPIPE is also what
CPython does. Note that this may lead to problems using MicroPython
scripts as pipe filters, but again, that's what CPython does. So,
scripts which want to follow unix shell pipe semantics (where SIGPIPE
means "pipe was requested to terminate, it's not an error"), should
catch EPIPE themselves.
Peer-closed socket is both readable and writable: read will return EOF,
write - error. Without this poll will hang on such socket.
Note that we don't return POLLHUP, based on argumentation in
http://www.greenend.org.uk/rjk/tech/poll.html that it should apply to
deeper disconnects, for example for networking, that would be link layer
disconnect (e.g. WiFi went down).
Make qstr generation depend on modifications in mpconfigport.h, mpconfig.h
and makeqstrdata.py and if any of those change scan all source files for
qstrs again since they might have changed (for example typcially when
enabling new features in mpconfig.h).
This fixes#2982 for msvc builds.
