Only compile-tested so far.
Of note is that the WiFi auto-connect (flag) functionality has been removed
from the IDF, and as a follow-on so has the "auto" field in the wifi config.
On the Ethernet side, support for the TLK110 PHY seems to have been removed,
but on the other hand there is now new support for several others.
Some parts dry-coded in the disabled modules; to be fixed when sorting out
the deprecated/removed APIs used in said modules.
Still untested beyond compile/linking.
Using the NODEMCU_ namespace prefix makes it obvious that these are not
part of Lua proper (contrast, e.g., LUA_BUILTIN_STRING). Using
"CMODULE" gives us room to differentiate between modules whose
implementation is in C and whose implemenation is in Lua ("LMODULE").
The ESP8266 branch can adopt the same convention when it moves to
Kconfig; see https://github.com/nodemcu/nodemcu-firmware/issues/3130
Manifests as multiple definition of esp_event_send during compilation, as bthci triggers inclusion of `event_loop.c`. Also improved lbth_init() to support BTDM or BLE_ONLY controller modes.
* Fix uart regressions & bugs.
Using `uart.on()` with a search character was broken in that it did
not invoke the callback on a full UART buffer as documented. Logic reworked
to match docs again.
Fixed memory leak on `task_post()` failure (eep!).
Improved logic to attempt to coalesce input bytes to reduce the number of
`task_post()` slots used up by the platform uart.
Finally, added a semaphore to prevent the platform uart from overrunning
the `task_post()` slots all the time on high baud rates (e.g. 1mbit).
With the semaphore in there, the LVM RTOS task gets a chance to actually
process the received data and free up a `task_post()` slot or two.
The above mentioned read coalescing then allows the platform uart to
immediately catch up.
Also added an error log message if the `task_post()` actually does fail.
* Don't cache the uart delims.
Doing so makes reconfiguring those settings from within the callback not
take effect until the currently buffered bytes have been processed.
To avoid races between the lwIP callbacks (lwIP RTOS task) and the Lua
handlers (LVM RTOS task), the data flow and ownership has been simplified
and cleaned up.
lwIP callbacks now have no visibility of the userdata struct. They are
limited to creating small event objects and task_post()ing them over
to the LVM "thread", passing ownership in doing so. The shared identifier
then becomes the struct netconn*.
On the LVM side, we keep a linked list of active userdata objects. This
allows us to retrieve the correct userdata when we get an event with
a netconn pointer. Because this list is only ever used within the LVM
task, no locking is necessary.
The old approach of stashing a userdata pointer into the 'socket' field
on the netconn has been removed entirely, as this was both not
thread/RTOS-task safe, and also interfered with the IDFs internal use
of the socket field (even when using only the netconn layer). As an
added benefit, this removed the need for all the SYS_ARCH_PROTECT()
locking stuff.
The need to track receive events before the corresponding userdata object
has been established has been removed by virtue of not reordering the
"accept" and the "recv" events any more (previously accepts were posted
with medium priority, while the receives where high priority, leading
to the observed reordering and associated headaches).
The workaround for IDF issue 784 has been removed as it is now not needed
and is in fact directly harmful as it results in a double-free. Yay for
getting rid of old workarounds!
DNS resolution code paths were merged for the two instances of "socket"
initiated resolves (connect/dns functions).
Also fixed an instance of using a stack variable for receiving the resolved
IP address, with said variable going out of scope before the DNS resolution
necessarily completed (hello, memory corruption!).
Where possible, moved to use the Lua allocator rather than plain malloc.
Finally, the NodeMCU task posting mechanism got a polish and an adjustment.
Given all the Bad(tm) that tends to happen if something fails task posting,
I went through a couple of iterations on how to avoid that. Alas, the
preferred solution of blocking non-LVM RTOS tasks until a slot is free
turned out to not be viable, as this easily resulted in deadlocks with the
lwIP stack. After much deliberation I settled on increasing the number of
available queue slots for the task_post() mechanism, but in the interest
of user control also now made it user configurable via Kconfig.
The netbuf_data() function only returns data from the first pbuf in the
chain. We need to use netbuf_first() and netbuf_next() to walk the
pbuf chain and act on each in turn.
* Leaner, meaner crypto module; now with HMAC
Based on my testing, mbedtls pulls in all its algorithm regardless of
whether the NodeMCU crypto module was using them or not. As such, the
space savings from omitting algorithms were only in the tens of bytes.
By switching to using the mbedtls generic message digest interface, the
crypto module itself could be shrunk in size and complexity. Despite
adding support for HMAC on all algorithms (plus including RIPEMD160),
this version is 330 bytes smaller.
* Updated crypto module docs.
* Removed superfluous brackets in crypto docs.
Copy-paste considered harmful... >.>
With the IDF asserting full control over the linker scripts and insisting on
the application description being the first entry in the .flash.rodata
section, or previous method of doing link-time arrays stopped working.
Why? Because the build patched in a SHA256 digest straight into our arrays.
With the limited language of the gcc linker scripts I could find no other
way of getting it in cleanly.
The IDF "linker fragments" support can not be made to work for our needs:
- no support for setting alignment before including objects
- no support for declaring symbols
- no support for adding our terminating zeros
- insists on grouping objects by lib rather than by declared grouping,
which means we could at most have a single link-time-array using
the IDF mechanism
- also does not like underscores in section names, but that's just an
annoyance
So, the least bad option that I could come up with was to use a project-wide
makefile snippet to add a target in-between the IDF's generation of the
esp32.project.ld file, and the linking of our NodeMCU.elf. In this target
we read in the esp32.project.ld linker script, check whether we have our
arrays in there, and if not rewrites the linker script.
Oh, and the esp32.project.ld file only came into existence on the IDF 3.3
branch, so I had to change up the IDF to the latest release/3.3 as well.
I would've preferred a stable tag, but the v3.3-beta3 had a really nasty
regression for us (can't add partition entry), so that was a no-go.
