* 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.
Use separate names for the integer and float `luac.cross` binaries. Also adds local/lua directory which is already supported by tools makefile to build LFS image.
* updated wifi_eventmon to store events in LUA_REGISTRYINDEX
* updated wifi_eventmon debug comments
* Updated wifi.c to remove c_free()
In wifi_ap_listclient(app/modules/wifi.c), c_free() was replaced with
wifi_softap_free_station_info()
* Removed unnecessary line of code from app/modules/wifi_eventmon.c
* fix application of patch 0018-feat-espconn-Modification-for-espconn.patch in #2269
espconn_tcp_reconnect() was removed instead of espconn_list_delete()
