* Logger & Channel classes now using AutoPtr<Channel> instead of Channel* (API improvement) * fix CachingChannel * more fixes * Configuration: remove raw pointers from interfaces #2077 * Add WeakPtr to Foundation #2246 * Add WeakPtr to Foundation #2246 (buildsystems files) * Add WeakPtr to Foundation #2246 (x64 VS project files) * backtrace and Event fixes * add ordered map * add ordered set * add sanitize makefiles * update RefPtr doc * fix AtomicCounter includes * add ordered containers tests * fix xml test compile error * remove operator bool rom smart pointers * Poco::strToInt<> fails for values right above the type's boundary / limit #2250 * add g++ -ftrapv config * remove Version.h includes (now included from Config.h) * comment out offending SQLite test (TODO) * add AtomicFlag and SpinlockMutex * remove RefCountedObject include from RefPtr and WeakRefPtr mutex template param * add WeakRef SpinLockMutex threading test * WeakRefPtr, backtrace, NDC, refcount DC fixes * SQL fixes * update RCO documentation * XML/DOM: Remove raw pointers from public interfaces #2075 * few fixes * PocoDoc - make logger non-static reference member * remove path char array initialization * Fix failing unit test, adding d in debug mode for TestApp and TestLibrary * fix application config pointer * fix some crypto warnings * fix Process tests and consolidate TestApp name building * define PathImpl::selfImpl for WinCE * restore WinCE test app name extension * attempt to passify 32 bit clang * fix failing Active* tests * Add POCO_OS_ANDROID support for Path::self() * Add build dependencies between Foundation-testrunner and TestApp, TestLibrary in cmake build * Remove to set LD_LIBRARY_PATH on foundation test * revert to develop XML * fix VS150 env not found (hardcode it) * undef min/max
