Greedily grab as much RMT memory as we can. It blocks other RMT
transmit channels but we only use it temporarily anyway. The more
we can grab, the fewer interrupts are needed to keep the transmit
going.
Flickers may still happen due to file system writes but most of the
time the animation just pauses.
On ESP32, move CircuitPython to the second core. This helps NeoPixel
by moving the RMT interrupt to the second core as well.
When testing ESP32 I noticed that settings.toml writes won't apply
until after hard reset. This removes that constraint but still
requires the password to enable the web workflow.
Fixes#3835
I've identified that this is a bottleneck when I am
refining documentation; by returning a bare minimum of data
to allow the doc build to complete, I can do more builds in less time.
To use, `env NO_BINDINGS_MATRIX= make html`
This changes storage.mount() to require that a mount point exist
on the parent file system.
A bug in background tasks is also fixed where the function
parameter is cleared on pending callbacks during "reset".
Disk usage is shown on the directory listing and changes based on
the mounted file system. Writable is also loaded per-directory.
Fixes#8108. Fixes#8690. Fixes#8107.
* Disable Nagle at the end of error messages so they are sent before
the socket is closed.
* Correctly discard file contents when the PUT file is too large.
* Correctly reset file size after failure to setting it too large.
* Change diskinfo.json to be list of disks in preparation of supporting
multiple disks.
* Bump version to 3 for the above change.
* Document diskinfo.json.
Fixes#8109
This changes from the previous limit of 15 characters. Although DHCP and
mDNS allow for up to 63, ESP32 and ESP8266 only allow 32, so this seems
like a reasonable limit to enforce across all ports (and avoids wasting the
additional memory).
Also clarifies that `MICROPY_PY_NETWORK_HOSTNAME_MAX_LEN` does not include
the null terminator (which was unclear before).

sdkconfig.base: Add CONFIG_BOOTLOADER_SKIP_VALIDATE_IN_DEEP_SLEEP=y.
This reduces time to boot from deepsleep by at least 200ms and can
provide significant power savings for deepsleep-based battery
applications.
docs/library/esp32.rst: Add note cautioning not to enter deepsleep after
changing the boot partition, without first performing a hard reset.

The primary purpose of this commit is to make decompress default to
wbits=15 when the format is gzip (or auto format with gzip detected). The
idea is that someone decompressing a gzip stream should be able to use the
default `deflate.DeflateIO(f)` and it will "just work" for any input
stream, even though it uses a lot of memory.
This is done by making uzlib report gzip files as having wbits set to 15
in their header (where it previously only set the wbits out parameter for
zlib files), and then fixing up the logic in `deflateio_init_read`.
Updates the documentation to match.

This is the minimum C interface to allow a modem driver to be built in
Python. Interface is simple, with the intention that the micropython-lib
driver is the main (only) consumer of it.

And put back our magic number, because our bytecode format differs
from upstream
drop btree & framebuf natmods, they had additional problems I didn't
want to fix right now.
Via MICROPY_GC_SPLIT_HEAP_AUTO feature flag added in previous commit.
Tested on ESP32 GENERIC_SPIRAM and GENERIC_S3 configurations, with some
worst-case allocation patterns and the standard test suite.
