Thanks. I found one before but I think it wasnt that one. I will try it. Iam experiencing random crashes on my esp and it seems it is because this linked list problem. I cant debug because its remote and I cant put serial to it

If you'd like to run your ESP application on a Linux computer, I wrote a bunch of stubs to do so: https://github.com/Depau/wi-se-sw/tree/main/fakeesp This is what allowed me to run this library with Valgrind/GDB and find the issues.

YMMV though, and I don't have time to provide any supports on them. Feel free to do whatever you want with the code, if you have any improvements lmk.

Thank you for the help. Your version of the library seems pretty stable. It runs almost 4 days straight now.
I got a crash like in 20 hours before. But i really get stable consistent file servings and client connection/disconnetions. I will look at your linux thingy too.
I really appreciate these and hope Me_no_Dev will see your fixes

@depau can you please pull latest me-no-dev master into your ``wi-se-patches` branch and push? It does not build otherwise.

No

@me-no-dev Is it planned to integrate this fix ? (#952). We are currently trying to port our software (WLED) to the new MCU's, and this one seems to cause troubles on -C3 and (maybe) -S2.

Another problem we run into on -S3 and -S2 is described in #1210 - "[E][vfs_api.cpp:29] open(): myFile.txt does not start with /"

Would be great if these issues could be solved.
We use LittleFS from arduino-esp32 v2.0.4, which seems to behave little different from the original "Lorol LittleFS" that we used for arduino-esp32 v1.0.6.

I opened a PR against the wi-se-patches branch here depau#1 to align it with its upstream

it's not much but at least if you're using a recent version of esp-idf with platformio you can simply point it to the fixed and up-to-date version with

replace in WebRequest.cpp

void AsyncWebServerRequest::_removeNotInterestingHeaders(){
  if (_interestingHeaders.containsIgnoreCase("ANY")) return; // nothing to do
  StringArray *a = &_interestingHeaders;
  auto cmpr = LinkedList<AsyncWebHeader*>::Predicate{[&a](AsyncWebHeader* h) {
    return !a->containsIgnoreCase(h->name().c_str());
  }};
  while (_headers.remove_first(cmpr)){}
}

or

void AsyncWebServerRequest::_removeNotInterestingHeaders(){
  if (_interestingHeaders.containsIgnoreCase("ANY")) return; // nothing to do
  StringArray *a = &_interestingHeaders;
  auto cmpr = LinkedList<AsyncWebHeader*>::Predicate{[&a](AsyncWebHeader* h) {
    return !a->containsIgnoreCase(h->name().c_str());
  }};
  _headers.remove_all(cmpr);
}

and add metod to class LinkedList in StringArray.h

    bool remove_all(Predicate predicate){
      auto it = _root;
      auto pit = _root;
      bool flag = false;
      while (it) {
        if(predicate(it->value())){
          auto d = it;
          if (it == _root) {
            _root = _root->next;
            pit   = _root;
            it    = _root;
          } else {
            pit->next = it->next;
            it = pit->next;
          }
          if (_onRemove) {
            _onRemove(d->value());
          }
          delete d;
          flag = true;
        } else {
          pit = it;
          it = it->next;
        }
      }
      return flag;
    }
