If the new name start with '/', cur_dir is not prepened any more, so that
the current working directory is respected. And extend the test cases for
rename to cover this functionality.
This change scans for '.', '..' and multiple '/' and normalizes the new
path name. If the resulting path does not exist, an error is raised.
Non-existing interim path elements are ignored if they are removed during
normalization.
This fixes the bug, that stat(filename) would not consider the current
working directory. So if e.g. the cwd is "lib", then stat("main.py") would
return the info for "/main.py" instead of "/lib/main.py".
The zephyr build system supports merging application-level board
configurations, so there is no need to reproduce this functionality in
MicroPython.
If CONF_FILE is not explicitly set, then the zephyr build system looks for
prj.conf in the application directory. Therefore we rename the MicroPython
prj_base.conf to prj.conf.
Furthermore, if the zephyr build system finds boards/$(BOARD).conf in the
application directory, it merges that configuration with prj.conf.
Therefore we rename all the MicroPython board .conf files and move them
into a boards/ directory.
The minimal configuration, prj_minimal.conf, is left in the application
directory because it is used as an explicitly set CONF_FILE in
make-minimal.
On arm64 with CPython:
>>> _thread.stack_size(32*1024)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: size not valid: 32768 bytes
So increase the CPython value in the test to 512k so it runs on more
systems (on modern Linux the default stack size is usually 8MB).
Constant expression like "2 ** 3" will now be folded, and the special form
"X = const(2 ** 3)" will now compile because the argument to the const is
now a constant.
Fixes issue #5865.
This commit adds several small items to improve the support for OTA
updates on an esp32:
- a partition table for 4MB flash modules that has two OTA partitions ready
to go to do updates
- a GENERIC_OTA board that uses that partition table and that enables
automatic roll-back in the bootloader
- a new esp32.Partition.mark_app_valid_cancel_rollback() class-method to
signal that the boot is successful and should not be rolled back at the
next reset
- an automated test for doing an OTA update
- documentation updates
For ports that have a system malloc which is not garbage collected (eg
unix, esp32), the stream object for the DB must be retained separately to
prevent it from being reclaimed by the MicroPython GC (because the
berkeley-db library uses malloc to allocate the DB structure which stores
the only reference to the stream).
Although in some cases the user code will explicitly retain a reference to
the underlying stream because it needs to call close() on it, this is not
always the case, eg in cases where the DB is intended to live forever.
Fixes issue #5940.
GPIO interrupts can occur when the flash ROM cache is in use and so the
GPIO interrupt handler must be in iRAM. This commit moves the handler to
iRAM, and also moves mp_sched_schedule to iRAM which is called by
pin_intr_handler.
As part of this fix the Pin class can no longer support hard=True in the
Pin.irq() method, because the VM and runtime are too big to put in iRAM.
Fixes#5714.
Explicitly add the repository as upstream and fetch the master commit.
This makes this bare-arm/minimal job more robust when finding the
fork-point of a PR relative to upstream/master (especially for forks of
this repo).
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.
But only when bluetooth is enabled, i.e. if building the dev or coverage
variants, and we have libusb available.
Update travis to match, i.e. specify the variant when doing
`make submodules`.
One can now use `-i micropython` and `-i cpython` to add instances using
the `MICROPYTHON` and `CPYTHON3` variables (which can be overridden by env
vars).
