Manual reboot () due to hardware watchdog in release mega-20180922 #1774

Closed micropet closed 5 years ago

micropet commented 6 years ago

The current version still has the same problem as the versions of the last few weeks. I use ESP_Easy_mega-20180922_test_ESP8266_4096.bin

The units without sensors run only slightly longer than one or four hours.

Units with Sensors (BME280 BH1750 Pir MH-Z19 TVoc CSS811 PMS7003) boot after a few minutes. The running time is between 3 minutes and 30 minutes. It is always different.

s0170071 commented 6 years ago

Looks like what I have seen. I did not observe an immediate crash either. It may also be a coincidence that my unit is now surviving longer. Crash or not, it looks like its worth an issue.

TD-er commented 6 years ago

Yesterday I made this commit: https://github.com/letscontrolit/ESPEasy/pull/1792/commits/bd2bdab95c102c700f4039540532858de8a30fa6 I tested it also on my ESP8266 and ESP32 and it seems to work. What it does is quite simple, it moves the allocation of the large SettingsStruct from stack to heap. My suspicion is that some of these crashes may happen due to stack overflow and moving such a large allocation on the stack to the heap may clear a lot of the very limited stack.

So maybe you could test that also on a number of nodes?

s0170071 commented 6 years ago

Maybe we should monitor the stack pointer ? This used to be good practice back in the days...

TD-er commented 6 years ago

If you can give me a pointer (pun intended) on how to do that, that would be great :)

s0170071 commented 6 years ago

Someone made some experiments here: https://www.esp8266.com/viewtopic.php?f=13&t=16734 There is even an issue open here: https://github.com/esp8266/Arduino/issues/5158 and https://github.com/esp8266/Arduino/issues/5148 The later one looks like there is already a method for checking the statck: getFreeContStack()

s0170071 commented 6 years ago

@TD-er: There is also a brute force approach:

  1. output a log message: "starting stack test..." ,
  2. wait for it to be sent out (10ms) and then
  3. do 100? nested function calls.

If the stack is low this will crash the system. Thanks to the log message you know why.

sample code:

in setup()

Serial.print(F("starting stack test..."));
if (stackTest(0)) Serial.println(F("  passed"));

the test function

boolean stackTest(int a ) {
    a++; 
    if (a<100) {
        stackTest(a);  // next nested call
    }
    a--; 
         if (a==0)  
             return true ;  // we're back to the first call
         else
             return false;  // this is still a nested loop
}

Each nested call should add at least 8 bytes to the stack, 4 for the int variable and 4 for the return address. If I am not mistaken that is. One would have to experiment with a healthy number of nested calls. Too many will crash the system, no matter what.

s0170071 commented 6 years ago

@Grovkillen that unknown command was just a coincidence. The unit rebooted after 18 hours.

Grovkillen commented 6 years ago

But might be some overload going on still?

TD-er commented 6 years ago

Did anyone test my suggestion ? I will merge that PR now, and it would be nice if someone could test it, before the nightly build is made.

N.B. when testing on ESP32, it will clear all your settings.

s0170071 commented 6 years ago

Isn't it too late for testing now ? You can tell only after a day or so if it is an success.

A good indication could be the stack test (with the nested calls) like I suggested here:

As far as I know we have no clue whatsoever how full the stack is. I would really like to know because that would finally give a plausible explaination why ESPEasy stability is often so bad..

I will test the stack this evening or tomorrow but I can't promise. Im very low on time in the evenings :-(

Hi Gijs, with latest releases, in my case the Hardware Watchdog is really random, some times the unit reboots after 2 hours, sometimes it doesn't reboot for days (now my units have been running for 2.5 days). So it's difficult to tell if your commit solves the issue.

Isn't it really possible to write catch the cause of the HW WD?

TD-er commented 6 years ago

@giig1967g Did you test with that specific commit? It was not merged until about an hour ago. @s0170071 I know that these commits don't break the units, since it has been running on my nodes for a while now. And the ESP32 merge should be done anyway, since with the default partitioning, you cannot add a lot with the latest core libraries. There was only a few kB left to add until building becomes impossible.

giig1967g commented 6 years ago

@giig1967g Did you test with that specific commit? It was not merged until about an hour ago.

Not yet. Will load now.

giig1967g commented 6 years ago

@giig1967g Did you test with that specific commit? It was not merged until about an hour ago.

How can I test your commit?

TD-er commented 6 years ago

It is already merged, so build from the mega branch.

giig1967g commented 6 years ago

built and loaded since 21 minutes. So far is ok

s0170071 commented 6 years ago

@TD-er I just tried the nested function calls. At the end of setup() I can make 224 nested calls before the ESP crashes. Whether the settings struct is on the heap or not makes no difference. I tried both.

What am I missing ? The settings as global variable could have been on the heap all along ? https://github.com/esp8266/Arduino/issues/3597#issuecomment-328718942

giig1967g commented 6 years ago

It is already merged, so build from the mega branch.

so far 9 hours and is ok. But it doesn't mean much as before uploading the firmware the unit ran for 6 days...

TD-er commented 6 years ago

@s0170071 Thanks for testing, too bad it doesn't seem to make a difference, but at least we can exclude something. The free heap is decreased by moving the settings struct to the heap. Only thing I can think of is that things allocated outside the setup() or loop() functions are maybe declared elsewhere. Not sure if it is on the Arduino stack, or maybe a stack outside the Arduino stack? (system stack?) I am thinking about moving back to 1.7.x core lib, since this one doesn't look like it can be solved in a short while.

micropet commented 6 years ago

I have increased the cip frequency to 160 MHz For me, the version of the 25th works now for over 10 hours without reboot on 3 units.

May be a coincidence.

s0170071 commented 6 years ago

@TD-er according to the message I linked only local variables end up on the stack. The settings struct was never local.

Have you ever had a look at the way strings are used ?

I mean, the crashes are rather random and we use a lot of strings in the code. E.g. returning a local string variable just a problem. It is out of scope if the calling routine tries to access it. That may (only may unfortunately) lead to problems. And there is heap fragmentation...

TD-er commented 6 years ago

True there may be heap fragmentation involved here. That's one of the reasons I added a check for the log level, to generate less log messages when nobody is listening. Also I try to use reserve where I can to prevent re-allocations on the heap. And allocating larger blocks at boot time, will also help to get at least those long lived blocks allocated close to eachother.

Also the rules do act a bit strange. Even on my ESP32 it sometimes reports memory as low as a few hundred bytes (from 180k free) and always in the same function for rules parsing. (see https://github.com/letscontrolit/ESPEasy/issues/1605 )

On ESP8266 issues list I asked also about the stack used here and they plan to add some functions to inspect stack and heap conditions. See: https://github.com/esp8266/Arduino/issues/5148#issuecomment-424334261 @devyte gives a very elaborate explanation there on the sys and the cont stack. I have to perform some tests myself to really understand what's happening here.

giig1967g commented 6 years ago

Regarding strings, what about defining only once, at boot time, global variables for strings that are always used several times per second: 1) log messages 2) string used in parsing arguments to recurring functions (parsetemplate, parsecommandstring, ruleMatch, etc.)

s0170071 commented 6 years ago

I just had a look at the logging addLog() and addToLog() and unless I got it wrong this is what happens (@TD-er please correct me)

  1. in some function a local String is generated.
  2. The reference to that string is passed to addLog and then addToLog
  3. The add method of the LogStruct class then stores this reference for later use. so far so good. What happens to those string references if "some function" returns ?
TD-er commented 6 years ago

As far as I know, the log does not keep references or pointers to strings that may get destructed after handed over to the log. If you see one of those, please tell me, since that will cause crashes for sure. Maybe not immediately, but in the end it will.

s0170071 commented 6 years ago

So did I understand that right ? I must NOT do this: 


void someFunction () {
 String log; 
 log = "hello world";
 addLog(LOG_LEVEL_DEBUG, log);
}
s0170071 commented 6 years ago

... or this: 

   String get_logjson_formatted(bool& logLinesAvailable, unsigned long& timestamp) {
 ...
      String output = logjson_formatLine(read_idx);
 ...
      return output;
    }
s0170071 commented 6 years ago

@TD-er (and all others... )

Just searching for "String" I find lots of paces that I find suspicious... Another one: 

bool getSettingsParameters(SettingsType settingsType, int index, int& offset, int& max_size);
String getSettingsTypeString(SettingsType settingsType) {
  switch (settingsType) {
    case BasicSettings_Type:            return F("Settings");

    ... more case statements....

    default:
      break;
  }
  return String();

}

What exactly doesreturn String(); return really ?

TD-er commented 6 years ago

Depends on what you do with the returned value. If you store it in an object, then there is no problem.

I don't have much time now, but I can explain more about this later this evening.

In short, this is tricky:

char* example() {
  String test = "this is a text";
  char* text = test.c_str();
  return text;
}

Problem is that the string will no longer exist after returning, so the pointer may point to something that can be used for something else. Returning a String is not a problem as long as the object remains.

micropet commented 6 years ago

No reboot since I increased the chip frequency to 160 MHz. 5 units are running with it.

Maybe it's worth a try.

TD-er commented 6 years ago

I wonder what would then be fixed by it. Is the uptime counter working OK?

micropet commented 6 years ago

I am surprised too.

Yes, the uptime counter is correct.

Maybe now the CPU can execute more commands at the same time.

giig1967g commented 6 years ago

It could make sense: the WD is activated after few seconds of non responding. So if the chip is faster it could be that it never reaches the WD limit...

how do you increase the CPU frequency?

micropet commented 6 years ago

In platformio only: board_build.f_cpu = 160000000L

TD-er commented 6 years ago

I also have the impression the reset of the WatchdogTimer is being done only at the end/start of a loop. That's one of the reasons I am trying to split a lot of tasks in smaller ones and only call one task per loop run.

s0170071 commented 6 years ago

Can we set the wd to shorter timeouts? Or lower the chip frequency? Just to trigger/ pinpoint the problem.

micropet commented 6 years ago

I think it works only 80 MHz and 160 MHz. But you can try 40 MHz.

giig1967g commented 6 years ago

I am testing the 160MHz. The web interface is really fast!

TD-er commented 6 years ago

I am not sure if higher CPU frequencies also imply higher flash frequencies. That may lead to data corruption. The CPU can run perfectly fine on that frequency.

micropet commented 6 years ago

board_build.f_flash stays at 40 MHz.

s0170071 commented 6 years ago

@TD-er my unit rebooted after a couple of hours. So the settings->heap commit did not do the trick. I added

    Serial.print(F("press key to boot..."));
    while (Serial.available()<5) delay(20);
    while (Serial.available()) Serial.read();

to the end of setup and have it logging via serial constantly. This way the unit is halted on reboot and I can look at the serial trace....

s0170071 commented 6 years ago

@TD-er this may be problematic: in ESPEasy-globals.h

    while (retry > 0 && !connected) {
      --retry;
      // In case of domain name resolution error result can be negative.
      // https://github.com/esp8266/Arduino/blob/18f643c7e2d6a0da9d26ff2b14c94e6536ab78c1/libraries/Ethernet/src/Dns.cpp#L44
      // Thus must match the result with 1.
      connected = (client.connect(getIP(), Port) == 1);
      if (connected) return true;
      if (!checkHostReachable(false))
        return false;
    }

it is not impossible that 3 consecutive connect attempts are made without feeding the WD.

TD-er commented 6 years ago

That's a good one.

s0170071 commented 6 years ago

@TD-er Just thinking: if you declare a function pointer to a void function like that: void (*MainLoopCall_ptr)(void); that pointer does not actually point anywhere yet, doesn't it ? So if you then do in loop()

if(MainLoopCall_ptr)
      MainLoopCall_ptr();

that's a bit like Russian roulette, :-O ?

TD-er commented 6 years ago

I don't know what you mean with the last remark. Do you have an actual example in the code where this is done?

Also the examples posted this morning where a String object is returned, do you have any example where it is being used incorrectly?

I will now look at your controller connect routine you mentioned and look at your other issue: https://github.com/letscontrolit/ESPEasy/issues/1814

s0170071 commented 6 years ago

void (*MainLoopCall_ptr)(void); is in ESPEasy-Globals.h

  if(MainLoopCall_ptr)
      MainLoopCall_ptr();

is in the main loop. With russian roulette I meant that jumping to an uninitialized pointer may end up deadly.

About the string pointers I am not sure. Two questions came to my mind:

  1. Can you really have a string object on the stack or is it just the pointer to that string ? Just like with the char array.
  2. What does return String(); do ?
TD-er commented 6 years ago

The String object is created on the stack. (unless called with new ofcourse ;) ) That String object has a few members:

The entire object itself is just a C++ object, just like any other struct/class.

return String(); does return a String object created with the default constructor (no parameters needed)

s0170071 commented 6 years ago

Thanks. And what about that void pointer ?

TD-er commented 6 years ago

I have to look into that. But as far as I know, a void pointer is just a pointer to some memory address. You have to cast it to something to actually know whether it is an object, a function or maybe some data.

So you can simply store just about anything inside a void pointer, but then you have to know what it is before using it, or else you will probably run into a crash or some undefined behavior.

Before de-referencing a pointer, you always have to check if it is a valid pointer, or really be sure about it (because you just created it for example)
