Ensure that connections are closed for error responses #346
Conversation
- This was endless fun to trace, but I found it at last. This should stop the `WARNING: A connection to https://api.github.com/ was leaked. Did you forget to close a response body?` messages in the logs when using the OkHttpConnector.

No I do not have an automated test for this fix, the testing I have done is to use the old version and run some code that is known to cause the issue... wait maybe 5 minutes (can show as early as immediately, seems to be at worst every 5 minutes) and then you get the error in the logs Then switch to the fix, rerun the same code (GHRepository.getCollaborators() with an anonymous connection is good) and then wait 15 minutes... no error logged! |

Maybe it;s a leftover from the previous fix. closeQuietlydoes not throw IOExceptions

uc.getInputStream() does

And when using the OkHttpConnector and the HTTP response code is >= 400 it will throw the IOE always (not that JVM's HttpURLConnection will do that)... given that this is the expected case for returning true, we need to access the error stream in order to ensure that the request is closed for the OkHttpConnector path... which we have to do using the error stream 🙄

Also https://github.com/square/okhttp/blob/parent-2.7.5/okhttp-urlconnection/src/main/java/com/squareup/okhttp/internal/huc/HttpURLConnectionImpl.java#L145 which is the only way to close the request body and prevent the warning!

@stepehenc have you tried to run existing ITs? |

@KostyaSha they fail for me before making changes, I do not expect them to magically pass after my changes, but I have done as extensive a testing as possible without the less than stellar automated tests |
