Memory leak in ESP8266HttpClient only when using SSL/TLS

[flyinggorilla]

Hardware

Arduino IDE 1.6.8
Hardware: Adafruit Huzzah
Core Version: 2.2.0

Description

ESP8266HTTPClient works fine in "http" mode. no leak. But when enabling SSL, it leaks 65 to 100 bytes per request (seems to depend on website how big the leak is). I tested different websites and on different Wifi connections. Other tests ran memory down from 30k free to 5k free after .GET() until it crashed. I even tried your latest libaxtls.a from master - since there were some recent fixes after 2.2.0, but no success.

Note: i tried HTTP keep-alive by also running it with .setReuse(true) following the "ReuseConnection" example code, with similar leak results.

Thanks for looking into this.

[jpmens]

I can confirm this using either GET or POST. I notice a leak of 72 octets (obtained with ESP.getFreeHeap()) for the site I'm accessing. I can also confirm that there's no leak (neither with GET nor with POST) when using plain HTTP (i.e. non-TLS).

[jpmens]

The JSON payload shown here demonstrates the free heap size remaining (_heap) until the device then crashes.

[djoele]

I notice the same results with latest Git checkout. After each request 72 bytes are not freed.

Will try some combinations of reUse and timeouts in the HTTP request. Perhaps that could help.

Some logging:

[HEAP] FreeHeap : 19904
[HTTP] url: /json.htm?type=command&param=udevice&idx=28&nvalue=0&svalue=60
[HTTP] url: /json.htm?type=command&param=udevice&idx=13&svalue=57

[HTTP] url: /json.htm?type=command&param=udevice&idx=14&nvalue=0&svalue=360;6858
[HEAP] FreeHeap : 19688

[HTTP] url: /json.htm?type=command&param=udevice&idx=12&svalue=2623
[HEAP] FreeHeap : 19280

[igrr]

The issue is due to a missing virtual destructor in the TransportTraits class.

[djoele]

thank you for the quick fix. Tonight I will check to see if the memory leak has been resolved. Will let you know the results.

[djoele]

@igrr: I can confirm that the latest Git checkout resolves the memory leak in https requests.

@Others: does it work for you too?

As far as I'm concerned the issue can be closed.

[flyinggorilla]

i can confirm the fix too. tested with 2.3.0-rc1.
THANK YOU for the fix.
