This is intended to be a more portable abstraction: rather than
hard-coding offsets in the macro invocations, it relies on the existence
of __builtin_offset and its availability even within inline asm blocks.
While here, rename some of the functions involved to hopefully improve
clarity
Discovered over on the dev-esp32-idf4 branch.
- Off by one error in loadLFS, leading to slight memory leak and
potential corruption.
- Insufficient return value check in loadLFS, where uzlib may return
one of two success conditions, one of which would result in an
out-of-bounds access and related pain.
- One case of a side effect within a lua_assert(), leading to
silently broken LFS image handling when compiling without asserts
enabled, the issue showing up as module names being shuffled around.
- Incorrect encoding of TValues in LFS when 64bit numbers in use.
LWIP_RAND() return type is int, value returned is sometimes negative.
This causes timer to sometimes (often) go outside of max_time, which in turn causes IGMP snoopers or IGMP routers to drop the subscription
While we intend our release strategy to be that we just fast-forward our
`release` branch to `dev`, things have come a little off the wheels.
This is a "git merge -s recursive -X theirs" of `dev` into `release`
instead.
- Changed the note about bme280_math dependency into a blue note box, like in the [bh1750 documentation](https://nodemcu.readthedocs.io/en/release/lua-modules/bh1750/)
- Added a paragraph on differentiating between BMP280 and BME280 sensors. It put it in an orange caution box for now, might be too visible for a rare problem.
- Small fixes in bme280.setup() description
* Rename to tests/README.md
* Expand tests/README.md a bit
* NTest: remove report() in favor of named fields
Use a metatable to provide defaults which can be shadowed by the calling
code.
* NTest: remove old interface flag
I think we have few enough tests that we can verify not needing this
alert for ourselves.
* NTest tests: new standard prelude
Allow for NTest constructor to be passed in to the test itself.
The test harness can use this to provide a wrapper that will
pre-configure NTest itself.
* NTest output handler for TAP messages
* expect tests: core library functions
* expect tests: file xfer TCL module
* expect tests: add TAP-based test runner
* Begin documenting TCL goo
* Add .gitattributes to make sure lineends are correct ...
... if checked out under windows and executed under linux (say docker)
* tests/README: enumerate dependencies
* tests: more README.md

* LiquidCrystal I2C 4-bit robustness
- Fix up some formatting
- Initialization is now more conformant with the datasheet.
- Read-backs don't needlessly (or erroneously!) store back
While here, document some unexpected behaviour of read-back commands.
* liquidcrystal i2c 4bit NTest
* apa102: remove dead code
We can't store strings of hundreds of thousands of characters in RAM, so
this can't possibly have fired, historically. Pixbufs are still RAM
objects, so that's still out. With LFS, it would take a pathological
example to hit the required 400KB TSTRING.
* Add IRQ management functions
* ws2812: fill UART FIFOs with IRQs off
Refactor code to make the use of two fill loops less gross.
`ws2812` buffer extracted to new `pixbuf` module.
* The new pixbuf module has more functionality than the `ws2812`-specific buffer it replaces.
* This is work in progress towards https://github.com/nodemcu/nodemcu-firmware/issues/2916
* The LED driver modules `ws2812`, `ws2801`, `apa102`, and `tm1829` have sprouted `pixbuf` support.
* `NTest` tests for `pixbuf` now exist.
While here, document the ws2812 UART-based overlapping with mainline
execution. Fixes https://github.com/nodemcu/nodemcu-firmware/issues/3140

* mqtt: remove concept of connection timeout
Just rely on the network stack to tell us when things have gone south.
* mqtt: remove write-only mqtt_state.port field
* mqtt: drop useless conditional
* mqtt: decouple message sent flag from timer
* mqtt: reconnect callback does not need to hang up
The network stack has certainly done that for us at this point.
Similarly, since we're about to call mqtt_socket_disconnected, don't
bother unregistering the timer here, either.
* mqtt: don't tick once per second
Set the timer for the duration of the wait and cancel it on the other side.
* mqtt: defer message queue destruction to _disconnect
We're going to want to publish a disconnect message for real, so doing
this in _close does no one any favors
* mqtt: miscellaneous cleanups
No functional change intended
* mqtt: close() should send disconnect message for real
This means waiting for _sent() to fire again before telling the network
stack to disconnect.
* mqtt: tidy connect and dns
- Push the self-ref to after all allocations and error returns
- Don't try to extract IPv4 from the domain string ourselves, let the
resolver, since it can
- Don't try to connect to localhost. That can't possibly work.
* mqtt: common up some callback invocations
* mqtt: don't retransmit messages on timeout
There's no point in retransmitting messages on timeout; the network
stack will be trying to do it for us anyway.
* mqtt: remove unnecessary NULL udata checks
* mqtt: hold strings in Lua, not C
Eliminates a host of C-side allocations.
While here, move the rest of the mqtt_connect_info structure out to its
own thing, and pack some flags using a bitfield.
* mqtt: mqtt_socket_on use lua_checkoption
* mqtt: slightly augment debug messages
These changes have made some debugging ever so slightly easier.
These have been handy within the test harness for streaming files and
LFS images across to the DUTs.
Add nrec method to pipe
