- Bug fixes and improvements
- FIX: Ensure that station is enabled before doing network scan (this seems to be the cause of #1578)
- FIX: Check if state == NULL on enduser_setup.stop()
- IMPROVEMENT: Look for both enduser_setup.html.gz and enduser_setup.html as valid filenames, for semantic reasons
- IMPROVEMENT: Show a generic status message on HTML page if failure occurred before user even submitted data (i.e., would have come from previously stored config when the STA was started by EUS)
Looks good to me. Thank you.
Also:
- allow for '\0's in received messages
* add client:config for setting websocket headers
Also:
- headers are case-insensitive now
* fix docs
* fix typo
* remove unnecessary luaL_argcheck calls
* replace os_sprintf with simple string copy
Squashed commits included:
Bug fixes and final implementation
- Added Content-Length: 0 to all headers
- Endpoint name checks not using trailing space so cache-busting techniques can be used (i.e., append a nonce to the URL)
- Track when connecting so APList scan doesn't take place during (which changes the channel)
- More debugging output added to assist in tracking down some issues
Added /status.json endpoint for phone apps/XHR to get JSON response
Station Status caching for wifi channel workaround + AJAX/CORS
- During checkstation poll, cache the last station status
- Shut down the station if status = 2,3,4 and channel is different than SoftAP
- Add Access-Control-Allow-Origin: * to endpoint responses used by a service
- Add a /setwifi GET endpoint for phone apps/XHR to use (same parameters as /update endpoint). Returns a JSON response containing chip id and status code.
- Add handler for OPTIONS verb (needed for CORS support)
Wi-Fi Channel Issue Workaround
- Do a site survey upon startup, set SoftAP channel to the strongest rssi's channel
- Compare successful station connect channel to SoftAP's. If different, then defer the Lua success callback to the end. Shut down Station and start the SoftAP back up with original channel.
- After the 10 second shutdown timer fires, check to see if success callback was already called. If not, then call it while starting the Station back up.
HTTP Response and DNS enhancements
- If DNS's UDP buffer fills up, keep going as non-fatal. It's UDP and not guaranteed anyways. I've seen this occur when connecting a PC to the SoftAP and every open program tries to phone home at the same time, overwhelming the EUS DNS server.
- Support for detecting/handling pre-gzipped `enduser_setup.html` (and `http_html_backup`) payload. Nice for keeping the size of the `state->http_payload_data` as small as possible (also makes minimization not as critical)
- Corrected misuse of HTTP 401 response status (changed one occurrence to 400/Bad Request, and changed another to 405/Method Not Allowed)
* Normalized formatting (tabs-to-spaces)
* Added documentation
* Corrected misuse of strlen for binary (gzip) data.
* Added NULL check after malloc
* Removed inline documentation for several functions and update comments
Since documentation is now part of the repository, the inline
documentation just adds to the already huge wifi.c
* Wifi module: add new functionality, update documentation
Functions Added:
wifi.getdefaultmode(): returns default wifi opmode
wifi.sta.apchange(): select alternate cached AP
wifi.sta.apinfo(): get cached AP list
wifi.sta.aplimit(): set cached AP limit
wifi.sta.getapindex(): get index of currently configured AP
wifi.sta.getdefaultconfig(): get default station configuration
wifi.ap.getdefaultconfig(): get default AP configuration
functions modified:
wifi.setmode: saving mode to flash is now optional
wifi.sta.config: now accepts table as an argument and save config to
flash is now optional
wifi.sta.getconfig: added option to return table
wifi.ap.config: save config to flash is now optional
wifi.ap.getconfig: added option to return table
Documentation changes:
- Modified documentation to reflect above changes
- Removed unnecessary inline documentation from `wifi.c`
- Updated documentation for `wifi.sta.disconnect`to address issue #1480
- Fixed inaccurate documentation for function `wifi.sleeptype`
- Added more details to `wifi.nullmodesleep()`
* Move function `wifi.sleeptype()` to `wifi.sta.sleeptype()`
* Fixed problem where wifi.x.getconfig() returned invalid strings when
ssid or password were set to maximum length.
* fix error in documentation for `wifi.sta.getapindex`
* Renamed some wifi functions
wifi.sta.apinfo -> getapinfo
wifi.sta.aplimit -> setaplimit
wifi.sta.apchange -> changeap
also organized the wifi_station_map array
* Add load/dump/mix/power operations on the buffer object
* Calculate the pixel value in mix and then clip to the range.
* Fixed the two wrong userdata types
* Added a couple more useful methods
* Add support for shifting a piece of the buffer.
* Fix a minor bug with offset shifts
* remove luaL_buffer from file_g_read()
- avoid memory leak when function gets terminated by lua_error
- skip scanning for end_char when reading until EOF
* attempt to free memory in any case
The esp_init_data_default.bin is now extracted from the SDK (and its
patch file, if present), and the contents are automatically embedded
into user_main.o.
To work around the pesky "rf_cal[0] !=0x05" hang when booting on a chip
which doesn't have esp_init_data written to it.
It is no longer possible to do the writing of the esp_init_data_default
from within nodemcu_init(), as the SDK now hangs long before it gets
there. As such, I've had to reimplement this in our user_start_trampoline
and get it all done before the SDK has a chance to look for the init data.
It's unfortunate that we have to spend IRAM on this, but I see no better
alternative at this point.
Input during startup (especially while doing initial filesystem format)
ran the risk of filling up the task queue, preventing the start_lua task
from being queued, and hence NodeMCU would not start up that time.
