This provides a more consistent C-level API to raise exceptions, ie moving
away from nlr_raise towards mp_raise_XXX. It also reduces code size by a
small amount on some ports.
Previous behaviour is when this argument is set to "true", in which case
the function will raise any pending exception. Setting it to "false" will
cancel any pending exception.
This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*. This matches the return type of
mp_thread_get_state(), which returns the same value.
`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.
Make version 4.1 and lower does not allow $call as the main expression on a
line, so assign the result of the $call to a dummy variable.
Fixes issue #5426.
Instances of the slice class are passed to __getitem__() on objects when
the user indexes them with a slice. In practice the majority of the time
(other than passing it on untouched) is to work out what the slice means in
the context of an array dimension of a particular length. Since Python 2.3
there has been a method on the slice class, indices(), that takes a
dimension length and returns the real start, stop and step, accounting for
missing or negative values in the slice spec. This commit implements such
a indices() method on the slice class.
It is configurable at compile-time via MICROPY_PY_BUILTINS_SLICE_INDICES,
disabled by default, enabled on unix, stm32 and esp32 ports.
This commit also adds new tests for slice indices and for slicing unicode
strings.
Move webrepl support code from ports/esp8266/modules into extmod/webrepl
(to be alongside extmod/modwebrepl.c), and use frozen manifests to include
it in the build on esp8266 and esp32.
A small modification is made to webrepl.py to make it work on non-ESP
ports, i.e. don't call dupterm_notify if not available.
Implements text, rodata and bss generalised relocations, as well as generic
qstr-object linking. This allows importing dynamic native modules on all
supported architectures in a unified way.
The compile-time configuration value MICROPY_HW_RTC_USER_MEM_MAX can now be
used to define the amount of memory set aside for RTC.memory(). If this
value is configured to zero then the RTC.memory functionality is not
included in the build.
The IDF heap is more fragmented with IDF 4 and mbedtls cannot allocate
enough RAM with 16+16kiB for both in and out buffers, so reduce output
buffer size.
Fixes issue #5303.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it. It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.
For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile. This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.
This commit adds support for littlefs (v2) on all esp32 boards.
The original FAT filesystem still works and any board with a preexisting
FAT filesystem will still work as normal. It's possible to switch to
littlefs by reformatting the block device using:
import uos, flashbdev
uos.VfsLfs2.mkfs(flashbdev.bdev)
Then when the board reboots (soft or hard) the new littlefs filesystem will
be mounted. It's possible to switch back to a FAT filesystem by formatting
with uos.VfsFat.mkfs(flashbdev.bdev).
When a SPI bus is initialized with a SPI host that is currently in use the
exception msg incorrectly indicates "SPI device already in use". The
mention of "device" in the exception msg is confusing because the error is
about trying to use a SPI host that is already claimed. A better exception
msg is "SPI host already in use".
For consistency with "umachine". Now that weak links are enabled
by default for built-in modules, this should be a no-op, but allows
extension of the bluetooth module by user code.
Also move registration of ubluetooth to objmodule rather than
port-specific.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found. This means that all modules named "ufoo" are always
available as "foo". Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.
It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.
Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
which saves code size, but will mean that "import foo" creates a new qstr
(namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
this reduces duplication in the help listing.
Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last. So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists. Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".
See issues: #1740, #4449, #5229, #5241.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest. This means that all file operations within a
manifest are relative to that manifest's location.
As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR). And rename $(MPY) to $(MPY_DIR) to be
consistent.
Existing manifests are updated to match.
Remove the 240MHz CPU config option from sdkconfig.base and create a new
sdkconfig.240mhz file for those boards that want to use 240MHz on boot.
The default CPU frequency is now 160MHz (was 240MHz), to align with the ESP
IDF and support more boards (eg those with D2WD chips).
Fixes issue #5169.
This prevents issues with concurrent access to the ringbuf.
MICROPY_BEGIN_ATOMIC_SECTION is only atomic to the same core. We could
address this with a mutex, but it's also not safe to call mp_sched_schedule
across cores.
This avoids a confusing ENOMEM raised from gap_advertise if there is
currently an active connection. This refers to the static connection
buffer pre-allocated by Nimble (nothing to do with MicroPython heap
memory).
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag). When this hash is detected, the relevant changes are
applied.
This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.
Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.
