This PR implements filters and removable routes in ESP8266 arduino core, making it API compatible with recent changes to ESP32 WebServer API.

Reference (Recent additions to ESP32 WebServer API):

Noteable Changes:

  1. Request Filters (setFilter)
  2. Removable Routes (removeRoute, removeHandler, _removeRequestHandler)

@me-no-dev , Please review this as well.

Not an Espressif repo (maybe ping @d-a-v). Will merge based on esp32 review, though.
Also, please take a look at 'doc/' and WebServer's 'README.md' and make sure everything is up-to-date w/ web documentation related to WebServer

Oh. I thought me-no-dev is a maintainer in this repo too.

I'll check documentation.

Any idea why LwIP CI tests are failing? Compiling on Arduino IDE locally doesn't show any error.

Great! Everything compiles now, what should we do about style test?

./tests/restyle.sh runs clang-format-15 on everything, chaining makes extra indentation

lose [&] and maybe do something explicit with 'on' return value?

auto& onlyAp = ...;
onlyAp.setFilter(ON_AP_FILTER);

I tried running ./tests/restyle.sh on my PC, odd enough that did nothing. Do we have to install anything for it to run?

Regarding Example:
I think it's better if we keep it same as ESP32 Filters.ino example, that way people are not confused.

clang-format-15 in $PATH / env CLANG_FORMAT=path-to-clang-format ./tests/restyle.sh

Right, but it definitely got me confused

  • [&] meant to capture by reference, but server callback should not do that. if you do it in setup() and capture value from there, later callback in loop() references invalid memory location
  • nothing is actually captured, don't wanna do that anyway

Specifically for us here and clang-format, without chaining - there are less spaces.
