* SoftUART fixes:
- Simplify code by using lua_L* functions and using userdata properly
- Fix some edge-cases
- Add more examples to documentation
* Don't de-register interrupt hook if there is more RX instances
* More bug fixes and registering simplification with luaL_reref and unref2
* Correct documentation of SoftUART module
* Change struct to use integers. This is slightly more complex as we have to deal with Unsigned 32-bit integers (that aren't lua integers)
* Use int64 in struct rather than double.
* Fix sjson to do the right things in LUA5.3 with integers and floats
I've not been able to get the mqtt `connfail` callback to work.
I'm consistently receiving `method not supported` errors:
```
application.lua:53: method not supported
stack traceback:
[C]: in function 'on'
application.lua:53: in main chunk
[C]: in function 'dofile'
init.lua:18: in function <init.lua:6>
```
Example code:
```
function on_connection_failed(client, reason)
print("mqtt connection failed: " .. reason)
end
m:on("connfail", on_connection_failed)
```
I believed this to be caused by the incorrect length comparison for `connfail`
that is updated here.
Once I changed that, the error went away, however the callback was never called.
I believe the callback was never called because of an incorrect assignment.
However, I saw this somewhat confusing description in the docs so this
assignment may be expected?
> The second (failure) callback aliases with the "connfail" callback available through :on(). (The "offline" callback is only called after an already established connection becomes closed. If the connect() call fails to establish a connection, the callback passed to :connect() is called and nothing else.)
* DHT module: fix the handling of negative temps.
The macro handling the conversion from the 2 bytes buffer to a double
was handling negative values by checking the sign bit and taking the
negative value of the number minus the sign bit.
Unfortunately this does not work as the negative values are represented
in 1's complement, so for instance -1 was becoming -32767
* +1 = b0000_0000_0000_ 0001
* -1 = 1111_1111_1111_1111
This replace the spacial code with a signed 16 bits value.
* Refactoring: removes some code duplication.
* Fixed the conversion of the 8/16 bits values

connecting to server.
Inside af426d0315, the `mqtt_socket_timer`
function was modified so that instead of checking the presense of
allocated `mud->pesp_conn` structure, `mud->connected` field was used
on determining if the timer need to be disarmed.
However, this is not entirely correct. If the TCP socket is actively
connecting and haven't timed out yet, then `mud->connected` is also
`false` and the timer will think the connection is broken and
disarms itself. This has two consequences:
* The connection timeout counter is no longer decremented and checked
* After connection succeeds, keepalive heartbeat is no longer being
sent (#3166). This is particularly noticeable in MQTT over TLS
connections, because those usually takes longer than 1 second
to finish and the timer would had chance to execute before connection
is established
This commit checks the presense of `pesp_conn->proto.tcp` pointer
instead, which was allocated in the same place as the (old) `pesp_conn`
struct, and according to my test indeed fixes the above issue.
It's not clear that this ever worked, AFAICT nobody uses it, and it's an
old version of the sqlite3 engine at this point. Absent a maintainer,
let's just get rid of it.
* Net_info module exposing ping function initial commit
* Ping as a part of net module
* Sent callback implemented
* Add NET_PING_ENABLE macro

- Lots of minor but nasty bugfixes to get all tests to run clean
- core lua and test suite fixes to allow luac -F to run cleanly against test suite
- next tranch to get LFS working
- luac.cross -a options plus fixes from feedback
- UART fixes and lua.c merge
- commit of wip prior to rebaselining against current dev
- more tweaks
* BMP085 pressure sensor: fix temperature value data type
the data type for t (U_T) should be long according to the BMP085
datasheet (rev. 1.2, section 3.5). values over 32767 can indeed occur,
and in my case lead to a wrong value for the temperature (and
consequently also pressure).
note: this problem only occurs above a certain temperature (exact
value depends on the calibration, but I assume somewhere around 26°C).
* BMP085 pressure sensor: adapt data types and calculation
this adapts the data types and calculation to be consistent with the
datasheet (rev. 1.2, section 3.5). while I did not notice any issues,
using the wrong data types could trigger edge cases.
Because the old API was inactive, we were setting
MBEDTLS_SSL_VERIFY_NONE even after we'd parsed the certificate.
tls tests now include a deliberate certificate mismatch; this was
discovered by moving the mqtt tests over to the new API.
Removes yet another unchecked allocation point in our C libraries.
While here, fix potential reference leaks on error paths
Also while here, remove some stale documentation. There can be as many
DNS requests in flight as LwIP has room for in its table
(DNS_TABLE_SIZE, which defaults to 4).
* espconn: remove unused espconn code, take 1
This is the easiest part of https://github.com/nodemcu/nodemcu-firmware/issues/3004 .
It removes a bunch of functions that were never called in our tree.
* espconn: De-orbit espconn_gethostbyname
Further work on https://github.com/nodemcu/nodemcu-firmware/issues/3004
While here, remove `mqtt`'s charming DNS-retry logic (which is neither
shared with nor duplicated in other modules) and update its :connect()
return value behavior and documentation.
* espconn: remove scary global pktinfo
A write-only global! How about that.
* net: remove deprecated methods
All the TLS stuff moved over there a long time ago, and
net_createUDPSocket should just do what it says on the tin.
* espconn_secure: remove ESPCONN_SERVER support
We can barely function as a TLS client; being a TLS server seems like a
real stretch. This code was never called from Lua anyway.
* espconn_secure: more code removal
* espconn_secure: simplify ssl options structure
There is nothing "ssl_packet" about this structure. Get rid of the
terrifying "pbuffer" pointer.
Squash two structure types together and eliminate an unused field.
* espconn_secure: refactor mbedtls_msg_info_load
Split out espconn_mbedtls_parse, which we can use as part of our effort
towards addressing https://github.com/nodemcu/nodemcu-firmware/issues/3032
* espconn_secure: introduce TLS cert/key callbacks
The new feature part of https://github.com/nodemcu/nodemcu-firmware/issues/3032
Subsequent work will remove the old mechanism.
* tls: add deprecation warnings
* luacheck: net.ifinfo is a thing now
* tls: remove use of espconn->reverse
* mqtt: stop using espconn->reverse
Instead, just place the espconn structure itself at the top of the user
data. This enlarges the structure somewhat but removes one more layer
of dynamic heap usage and NULL checks.
While here, simplify the code a bit.
* mqtt: remove redundant pointer to connect_info
Everywhere we have the mqtt_state_t we also have the lmqtt_userdata.
* mqtt: doc fixes
* mqtt: note bug
* tls: allow :on(...,nil) to unregister a callback
* mqtt: expose "connfail" callback via :on()
This makes it just like all the other callbacks in the module and is a
revision of behavior called out in
https://github.com/nodemcu/nodemcu-firmware/pull/2967
* mqtt: clarify when puback callback fires
* mqtt: Don't reference stack buffers from the heap
The confusingly-named "mqtt_connection_t" object is just a triple of
- a serialized mqtt message pointer and length
- a buffer pointer (to which the above can be written)
- a message identifier
The last of these must be passed around the mqtt state machine, but the
first two are very local and the buffer is always sourced from the C
stack. Unfortunately, because the entire structure is persisted in the
heap, some callers assume that they can always use the structure without
reinitialization (see mqtt_socket_close), which will trash the C stack.
Sever the pairing between message id and local state, punt the local
state entirely out of the heap, and rename things to be less confusing.
