What’s Fixed in POCO 1.7.1?
There are three notable fixes in this new version. First off there is a bug fix dealing with seeing frequent “MySQL server has gone away” errors. Next when attempting to connect via a proxy, the library was throwing a DNS error “Host not found”. Finally there was an internal possible deadlock bug when TaskManager::count() is called in onFinished. Also as a new feature, TLS is enforced over SSL if OpenSSL version is greater than or equal 1.1.
