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.

* 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.
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.
* Remove app/include/netif/wlan_lwip_if.h
This file appears to be unused in our tree.
* New `net.if.info` call to show LwIP information
This is a generalization of `wifi.sta`'s and `wifi.ap`'s `getip` and
`getmac` calls. I don't propose to deprecate those, but perhaps we
should, in the documentation, point users at this function instead.
The direct motivation is to permit continued use of DHCP-provided NTP
servers in a future where
https://github.com/nodemcu/nodemcu-firmware/pull/2819 has landed, now
that https://github.com/nodemcu/nodemcu-firmware/pull/2709 is in the
tree. But rather than exposing just that information, a more general
interface seems useful.
The internal implementation already preferentially forwards to the
encoder module, so we should just remove these functions as they confuse
people into thinking that we don't have their inverses (see the feature
request https://github.com/nodemcu/nodemcu-firmware/issues/2907).
Update the docs to refer to the encoder version and add deprecation
warnings to the runtime implementations.
* list_ref can become LUA_REFNIL, because that's what rawgeti returns
for LUA_NOREF. Defensively guard for this, rather than falling into
the sntp_dolookups loop with nil on the stack.
* set_repeat_mode should not call itself, but should rather always do
what it's going to do and then optionally do the rest if directed.
* sntp_sync should not try to special case the single string argument:
we should be queueing that name for DNS resolution, too. Towards that
end, if we are given a single string, build a table and make that the
list_ref and call off to sntp_dolookups, just like we otherwise do.
FIXES: #2699
The PR removed the bulk of non-newlib headers from the NodeMCU source base.
app/libc has now been cut down to the bare minimum overrides to shadow the
corresponding functions in the SDK's libc. The old c_xyz.h headerfiles have been
nuked in favour of the standard <xyz.h> headers, with a few exceptions over in
sdk-overrides. Again, shipping a libc.a without headers is a terrible thing to do. We're
still living on a prayer that libc was configured the same was as a default-configured
xtensa gcc toolchain assumes it is. That part I cannot do anything about, unfortunately,
but it's no worse than it has been before.
This enables our source files to compile successfully using the standard header files,
and use the typical malloc()/calloc()/realloc()/free(), the strwhatever()s and
memwhatever()s. These end up, through macro and linker magic, mapped to the
appropriate SDK or ROM functions.
* mqtt:connect() secure parameter should be boolean
Continue to honor the old 0/1 values, but make them undocumented and add
a deprecation warning to the code and docs. Eventually, this should go
away.
* mqtt: rip out deprecated autoreconnect
* mqtt: expose all the callbacks via :on
* Use cross-browser JS for query params in EUS
* Update EUS doc to explain how to use parameters
* Remove ; in Lua code
* Rewrite the endpoint table
* Do not use properties as global Lua variables
* remove enduser_setup.html.gz
* rename folder 'eus' to 'enduser_setup'
* Change input type for password to "password"
* Replace outdated captive portal screen shot
* Upgrade u8g2 and add updateDisplayArea bindings
* u8g2 2.25.10
* add displays for 2.24.3 and 2.25.10
* remove workaround for hal pointer and make use of u8x8's user_ptr
* fix doc
* add binding for `updateDisplay()`
* Lua string optimisation in file.c + get/put contents methods
* Doc fix: move putcontents() into correct alphabetic order slot in list of static methods
* Rebaseline firmware to non-OS SDK version 3.0
* Note that SDK version 3.0 introduces the concept of a Flash Partition Table(PT). This is located at Flash offset 0x10000 in our firmware build.
* The firmware is now PT aware with both LFS and SPIFFS taking their partition size and location from the PT
* A new tool `tools/nodemcu-partition.py` is now used to initialise these data and can also download LFS and SPIFFS images to these partitions.
* I2C driver speed-up, i2c.SLOW, i2c.FAST and user-defined speed selection
* - Multiple buses (up to 10) with different speeds on each bus
- Standard(Slow, 100kHz), Fast(400kHz) and FastPlus(1MHz) modes or an
arbitrary clock speed
- Sharing SDA line over multiple I²C buses to save available pins
- GPIO16 pin can be used as SCL pin, but it does not support clock
stretching and selected bus will be limited to FAST speed.
* Dynamic memory allocation, error checks, simplification, timing tweaks.
* Separated the code of old driver for better compatibility and simplicity
* Change of driver interface
* Add bus status check in setup(); simplify getDC(); remove unnesessary lines in ACK read/write
* Fix for moved doc file and trailing whitespaces
* Update TLS protocol support
TLS1.0 is past PCI's EOL; BEAST is no more
Enable elliptic curve key exchanges
Do not enable the smallest ECs for security
Do not enable the largest ECs for computational time
Do not enable 25519 (sad) because it doesn't go across the wire
Drop non-PFS key exchanges
Drop ARC4, Blowfish, DES, genprime, XTEA code
Drop renegotiation support completely
It takes so much heap that it's not likely to work out well
Tidy handling of SSL_BUFFER_SIZE
Update docs
Drop mention of startcom, since they are no more, for letsencrypt
* Update mbedtls to 2.7.7
Preserve our vsnprintf and platform hacks
* Introduce TLS maximum fragment size knob
Reduce buffer size to 4Ki by default and advertize that. That's the
largest we can advertize with the TLS MFL extension, so there's no
point in making them larger. The truly adventurous can re-raise
SSL_BUFFER_SIZE and undefine the SSL_MAX_FRAGMENT_LENGTH_CODE and get
back to the earlier behavior.
* Default to mbedTLS debug with DEVELOP_VERSION
* Add spi.set_clock_div
This will allow the SPI clock divider to be changed relatively simply,
to better support multiple devices with varying SPI clock rate support
* Add documentation
* MQTT: handle large/chunked/fragmented messages properly
If a message spans multiple TCP packets it must be buffered before
delivered to LUA. Prior code did not do this at all, so this "patch"
really adds proper handling of fragmented MQTT packets.
This could also occur if multiple small messages was sent in a
single TCP packet, and the last message did not completely fit in that
packet.
Introduces a new option to the mqtt.Client constructor:
max_publish_length which defaults to 1024
Introduces a new 'overflow' callback.
Fixes issue #2308 and proper fix for PR #2544.
* mqtt.md: clarified heap allocation
* mqtt: ensure ack is sent for overflowed publish
If QoS is used we should still acknowledge that we received it, or server might retransmit it later.
The volume returned by file.mount() could not be unmounted, because vol:umount() would fail with a cryptic error about the uncallable nature of the volume userdata object. This was due to the wrong metatable name being used for setting up the volume structure. The correct name, as registered elsewhere in file.c, is now used, and vol:umount() is callable.
Any TCP packet with more than 1024 bytes of payload was silently
dropped. With MTU of 1500 the TCP payload can be up to 1460 bytes
(1500 - 20(IP hdr) - 20(TCP hdr))
- Optimise ROTable accesses and interface
This includes some refinements to the ROTable cache which remove the linker cludges on the CROSS_COMPILE builds. Also keyhole tweaks to some of the Lua VM code to implrove runtimes.
I also noticed some compile time warnings during the build; the change to uz_unzip.c doesn't impact the compiled code, but does remove the compiler warnings.
