Incompatible Changes and Possible Transition Issues

Crypto and NetSSL on Windows: The included Visual Studio project files now expect the OpenSSL headers and libraries to be in the "openssl" directory in the POCO root directory, alongside the Foundation, XML, Net directories. The GitHub repository contains the openssl submodule, which has the required files. The release source packages do not contain these files. They are available from the pocoproject/openssl repository (Zip archive). You can also provide your own build of OpenSSL, by specifying the appropriate header and library search paths in the Visual Studio project files. Through the Poco/Crypto/Crypto.h and Poco/Net/NetSSL.h headers, the libcrypto.lib and libssl.lib libraries will be automatically linked. If you don't want this, build Crypto and NetSSL_OpenSSL with the POCO_EXTERNAL_OPENSSL macro defined.

Incompatible Changes and Possible Transition Issues

Data::ODBC: UTF-16 Unicode is now directly mapped and recognized as type by ODBC. This may cause behavior different from previosu versions, especially with Any and Dynamic::Var bindings. In this release, UTF-16 binding is only available for ODBC back end; although other back ends will compile with UTF-16 strings bound, such binding attempt will throw NotImplementedException at runtime.
Please note that 1.5.x releases are development releases and not considered stable. Interfaces may change, and backwards compatibility with the stable 1.4 release series is not guaranteed. There may also be some rough edges. The next stable release incorporating 1.5 features will be 1.6.

JSON::DefaultHandler was renamed to a more appropriate name - ParseHandler; ParseHandler does not have to be passed to the Parser, it will be used by default; handlers are now passed into Parser as smart pointers, so passing in addresses of stack objects will cause undefined behavior
Please note that 1.5.x releases are development releases and not considered stable. Interfaces may change, and backwards compatibility with the stable 1.4 release series is not guaranteed. There may also be some rough edges. The next stable release incorporating 1.5 features will be 1.6.

Poco::Zip::ZipStreamBuf: fixed a crash if CM_STORE was used.
Added setContentLength64() and getContentLength64() to Poco::Net::HTTPMessage.
added Poco::Environment::osDisplayName().
fixed SF# 3463096: WinService leaves dangling handles (open() now does not reopen the service handle if it's already open)
fixed SF# 3426537: WinRegistryConfiguration can't read virtualized keys
added Poco::Buffer::resize()
fixed SF# 3441822: thread safety issue in Poco::Net::HTTPClientSession: always use getaddrinfo() instead of gethostbyname() on all platforms supporting it
added version resource to POCO DLLs
fixed SF# 3440599: Dir Path in Quotes in PATH cause PathTest::testFind to fail.
fixed SF# 3406030: Poco::Glob::collect() problem
added Poco::Util::AbstractConfiguration::enableEvents()
Poco::AtomicCounter now uses GCC builtins with GCC 4.1 or newer (contributed by Alexey Milovidov)
made Poco::Logger::formatDump() public as it may be useful for others as well (SF# 3453446)
Poco::Net::DialogSocket now has a proper copy constructor (SF# 3414602)
Poco::Net::MessageHeader and Poco::Net::HTMLForm now limit the maximum number of fields parsed from a message to prevent certain kinds of denial-of-service attacks. The field limit can be changed with the new method setFieldLimit(). The default limit is 100.
Poco::NumberFormatter, Poco::NumberParser and Poco::format() now always use the classic ("C") locale to format and parse floating-point numbers.
added Poco::StreamCopier::copyStream64(), Poco::StreamCopier::copyStreamUnbuffered64() and Poco::StreamCopier::copyToString64(). These functions use a 64-bit integer to count the number of bytes copied.
upgraded internal zlib to 1.2.5
upgraded internal sqlite to 3.7.9
XML: integrated bugfix for Expat bug# 2958794 (memory leak in poolGrow)
Added support for HTTP Digest authentication (based on a contribution by Anton V. Yabchinskiy (arn at bestmx dot ru)). For information on how to use this, see the Poco::Net::HTTPCredentials, Poco::Net::HTTPDigestCredentials and Poco::Net::HTTPAuthenticationParams classes.
Poco::Net::HTTPStreamFactory and Poco::Net::HTTPSStreamFactory now support Basic and Digest authentication. Username and password must be provided in the URI.
added Poco::Net::WebSocket, supporting the WebSocket protocol as described in RFC 6455
NetSSL_OpenSSL: added client-side support for Server Name Indication. Poco::Net::SecureSocketImpl::connectSSL() now calls SSL_set_tlsext_host_name() if its available (OpenSSL 9.8.6f and later).
added Poco::Net::HTTPClientSession::proxyConnect() (factored out from Poco::Net::HTTPSClientSession::connect())
added Poco::Process::kill(const Poco::ProcessHandle&) which is preferable to kill(pid) on Windows, as process IDs on Windows may be reused.
fixed SF# 3471463: Compiler warnings with -Wformat
Poco::Util::Application::run() now catches and logs exceptions thrown in initialize()
Fixed a WinCE-specific bug in Poco::Util::ServerApplication where uninitialize() would be called twice.
fixed SF# 3471957: WinRegistryKey::deleteKey() unable to delete alt views
Added additional constructor to Poco::ScopedLock and Poco::ScopedLockWithUnlock accepting a timeout as second argument.
Added Poco::Logger::parseLevel()
Poco::format(): an argument that does not match the format specifier no longer results in a BadCastException. The string [ERRFMT] is written to the result string instead.

Release 1.4.2p1

Summary of Changes

On Linux, the RTLD_DEEPBIND option is no longer passed to dlopen(). This change was introduced in 1.4.2 to solve a specific problem one customer was having. Unfortunately, it leads to problems with RTTI.
It's now possible to pass flags (SHLIB_GLOBAL, SHLIB_LOCAL) to Poco::SharedLibrary::load() (and the constructor implicitly calling load()), controlling the mode flags (RTLD_GLOBAL, RTLD_LOCAL) passed to dlopen(). On platforms not using dlopen(), these flags are ignored.
fixed SF# 3400267: Path_WIN32.cpp bug

Release 1.4.2

Summary of Changes

added Poco::DateTimeFormat::ISO8601_FRAC_FORMAT
added new Poco::DateTimeFormatter and Poco::DateTimeParser format specifier: %s for seconds with optional fractions of a second
fixed a problem with ioctl() on BSD platforms (including OS X) where the second argument to ioctl() is unsigned long instead of int, causing bad things on a OS X 64-bit kernel.
fixed a potential endless loop when enumerating IPv6 network addresses (reported by Laurent Carcagno)
new compile-time config option on Windows to set thread names in debugger. Enable with -DPOCO_WIN32_DEBUGGER_THREAD_NAMES. Available only in debug builds.
Cipher can now create Base64 and HexBinary encoded output without linefeeds (suitable for use in cookies, etc.)
added Poco::Path::popFrontDirectory()
improved VxWorks support
IPv6 fixes: added proper scope id handling in IPAddress, SocketAddress and related classes.
Added Poco::Net::ServerSocket::bind6() which allows control over the IPPROTO_IPV6/IPV6_V6ONLY socket option.
Removed Poco::MD2Engine class due to licensing issues (the license for the MD2 code from RSA only allows non-commercial use). Note that the MD4 and MD5 code from RSA does not have this issue.
fixed a Net HTTP client testsuite issue where some tests might have failed due to prematurely aborted connections by the HTTPTestServer.
Poco::Net::SocketAddress: when there is more than one address returned by a DNS lookup for a name, IPv4 addresses will be preferred to IPv6 ones.
Poco::Net::NetworkInterface::list() now also returns IPv4 interfaces on Windows when built with -DPOCO_HAVE_IPv6
Poco::XML::XMLWriter: fixed a bug with attribute namespaces (no namespace prefix written if attribute namespace is the same as element namespace)
fixed SF# 3378588: Mismatched new[]/delete (in RSAEncryptImpl and RSADecryptImpl)
fixed SF# 3212954 (OpenSSLInitializer::uninitialize() crash) and SF# 3196862 (Static OpenSSLInitializer instance causes Windows deadlocks) by removing the static Poco::Crypto::OpenSSLInitializer instance. Automatic OpenSSL initialization is now done through Poco::Crypto::Cipher, Poco::Crypto::CipherKey, Poco::Crypto::X509Certificate, Poco::Net::Context classes; however, it is still recommended to call Poco::Crypto::initializeCrypto() and Poco::Crypto::uninitializeCrypto() early at application startup, and late at shutdown respectively (or Poco::Net::initializeSSL()/Poco::Net::uninitializeSSL() if the NetSSL library is used) to avoid multiple full OpenSSL init/uninit cycles during application runtime.
Poco::Logger now also support a symbolic log level "none" (for use with setLevel()) that disables logging completely for that Logger (equivalent to setLevel(0)).
Added experimental Android support, using the existing gmake-based build system.
fixed SF# 3288584: DateTimeFormatter link error
fixed SF# 3187117: Typo in InflatingInputStream doc
fixed SF# 3309731: _WIN32_WCE comparison should be with 0x600 not 600
fixed SF# 3393026: RegularExpression.h identical enum value
fixed SF# 3274222: AtomicCounter's postfix operators aren't atomic on Windows
fixed SF# 3317177: Handle leak on windows
fixed SF# 3181882: Poco::URI::getPathEtc() double-encodes query
fixed SF# 3379935: Poco::ThreadPool Start Bug
fixed SF# 3354451: Poco::Format::parsePrec() never sets the precision to zero
fixed SF# 3387258: _MAX_PATH used but unknown in Path_WIN32
fixed a problem in Poco::Crypto::RSAKeyImpl where direct access to the RSA in a EVP_PKEY would no longer work in recent OpenSSL versions. Using EVP_PKEY_get1_RSA() fixes the issue.
added Poco::Crypto::EncryptingInputStream, Poco::Crypto::EncryptingOutputStream, Poco::Crypto::DecryptingInputStream and Poco::Crypto::DecryptingOutputStream.
fixed SF# 3148126: Poco::Net::HTTPSClientSession destructor throws an IOException
fixed SF# 3178098: Add constructor to Poco::TemporaryFile to specify directory
fixed SF# 3175310: Absolute path when device
fixed SF# 3301207: Guided tour example contradicts apidoc (API doc was wrong)
Poco::Net::HTTPMessage::setContentLength() and Poco::Net::HTTPMessage::getContentLength() now use std::streamsize instead of int. This enables 64-bit Content-Length support at least on 64-bit platforms.
fixed SF# 3177530: Poco::TemporaryFile::tempName() + glob bug on xp
fixed SF# 3177372: Poco::FileChannel documentation inconsistency
added %E format specifier to Poco::PattermFormatter (epoch time in seconds since midnight, January 1 1970)
On Windows, Poco::Util::ServerApplication now supports a /description command line argument for specifying a service description (together with /registerService)
added Poco::Util::WinService::setDescription() and Poco::Util::WinService::getDescription()
fixed SF# 3155477: Incorrect URI path handling
fixed SF# 3309736: Extended Exception macros to set default exception code new macro is named POCO_DECLARE_EXCEPTION_CODE
added getter functions for modulus and exponents to Poco::Crypto::RSAKey.
added Poco::Net::SocketAddress::operator == () and Poco::Net::SocketAddress::operator != ()
fixed SF# 3182746: IPAddress.cpp IPv6 bug on big-endian
fixed SF# 3196961: Unix daemon fails to loadConfiguration() if started from cwd
fixed SF# 3393700: NotificationCenter may call a removed observer and crash.
Reworked implementation of the events framework (Poco::BasicEvent and friends). The framework is now completely multithreading save (even in the case that an event subscriber object unsubscribes and is deleted while an event is being dispatched). Also, the restriction that any object can only register one delegate for each event has been removed. For most cases, dispatching events should be faster, as dispatching an event now needs less dynamic memory allocations.
fixed SF# 3178109: getNodeByPath() changes: getNodeByPath() and getNodeByPathNS() have been moved to Poco::XML::Node. Furthermore, when invoked on a Poco::XML::Document, the behavior has changed so that the document element is now included when traversing the path (previously, traversal would start at the document element, now it starts at the document). The path expression can now start with a double-slash, which results in a recursive search for the path's first element in the DOM tree.
fixed SF# 3382935: String data being truncated using ODBC, and SF# 2921813: Wrong implementation of the ODBC string binding

Release 1.4.1p1

Summary of Changes

Poco::Mutex is now a recursive mutex again on Linux (this was caused by an unfortunate feature test for PTHREAD_MUTEX_RECURSIVE which did not work on Linux as PTHREAD_MUTEX_RECURSIVE is an enum value and not a macro)
Poco::Net::SecureSocketImpl::abort() now only shuts down the underlying socket connection and does not free the SSL object, due to multithreading issues.

Release 1.4.1

Summary of Changes

fixed SF# 3150223: Poco::BinaryReader cannot read std::vector correctly
fixed SF# 3146326: Poco::SharedMemory issue
made Poco::Net::HTTPSession::abort() virtual
added Poco::Net::SecureStreamSocket::abort() to immediately close a SSL/TLS connection without performing an orderly SSL/TLS shutdown.
fixed SF# 3148126: Poco::Net::HTTPSClientSession destructor (!) throws an IOException. Added try/catch block to Poco::Net::SecureSocketImpl destructor.
added additional constructor to Poco::Net::HTTPSClientSession, taking both a socket and a session object.
Poco::Net::HTTPSession::abort() now also can be used with a Poco::Net::HTTPSClientSession.
fixed SF# 3148045: make clean and distclean issues
changed Data library names on Unix/Linux platforms to match the names on Windows (PocoSQLite -> PocoDataSQLite, PocoMySQL -> PocoDataMySQL, PocoODBC -> PocoDataODBC)
added additional options to configure script
added additional documentation to Poco::Net::HTTPClientSession
Poco::Net::HTTPClientSession::receiveResponse() closes the connection if an exception is thrown while reading the response header. This ensures that a new connection will be set up for the next request if persistent connections are used.
improved Poco::Net::MultipartDecoder performance by reading directly from streambuf
improved performance of Poco::Base64Encoder, Poco::Base64Decoder, Poco::HexBinaryEncoder and Poco::HexBinaryDecoder by working directly with the given stream's streambuf.
improved performance of MessageHeader::read() by reading directly from streambuf instead of istream.
it is now possible to specify additional MIME part header fields for a MIME part through the Poco::Net::PartSource class.
upgraded SQLite to release 3.7.4
added experimental VxWorks support for VxWorks 5.5.1/Tornado 2.2 and newer. Please see the VxWorks Platform Notes in the reference documentation for more information. Currently, the VxWorks is untested; full support will be available in release 1.4.2.
fixed SF# 3165918: Poco::DynamicAny fails to convert from string to float
fixed SF# 3165910: Poco::Net::MessageHeader does not accept HTTP conforming header
made Poco::Task::cancel() virtual so that tasks can implement custom cancellation behavior.
added optional argument to Poco::Util::WinRegistryKey constructor to specify additional flags (in addition to KEY_READ and KEY_WRITE) for the samDesired argument of RegOpenKeyEx() or RegCreateKeyEx().
improved Poco::BasicEvent::notify() performance by avoiding an unnecessary heap allocation.
added additional well-known port numbers to Poco::URI: rtsp, sip, sips, xmpp.
added Poco::Net::MediaType::matchesRange()
improved invalid socket handling: a Poco::Net::InvalidSocketException is now thrown instead of an assertion when an operation is attempted on a closed or otherwise uninitialized socket.

Release 1.4.0

Summary of Changes

Poco::Net::SSLManager: documentation fixes, code cleanup
Poco::Net::SSLManager: renamed PrivateKeyPassPhrase event to PrivateKeyPassphraseRequired
added Poco::Net::HTTPServerRequestImpl::socket() to get access to the underlying socket
added Poco::Net::Socket::secure() to find out whether a given socket supports SSL/TLS
added Poco::Net::SecureStreamSocket::havePeerCertificate()
NetSSL: added support for turning off extended certificate validation (hostname matching)
fixed SF# 2941228: Poco::Net::ICMPClient::ping() issues on Mac OS X
fixed SF# 2941231: Poco::Net::ICMPEventArgs out of bounds array access
added PageCompiler sample
added missing newline at end of xmlparse.c
Poco::Glob can now be used with an empty pattern which will match nothing (patch from Kim Graesman)
added support for HTTP proxy authentication (Basic authentication only)
fixed SF# 2958959: Poco::XML::XMLWriter must encode CR, LF and TAB in attribute values as character entities.
Poco::Net::HTMLForm now supports PUT requests as well (see <http://pocoproject.org/forum/viewtopic.php?f=12&t=2163&p=3930#p3930>)
fixed SF# #2970521: Poco::FileOutputStream and file permissions. (also fixed in File class)
removed an unused (and wrong) default parameter from EventImpl constructor for WIN32.
added full support for session caching to NetSSL_OpenSSL
fixed SF# 2984454: Poco::Util::Timer::scheduleAtFixedRate() works incorrectly
fixed a bug in Poco::Util::Timer that could lead to high CPU load if the system clock is moved forward.
added "system.nodeId" property to Poco::Util::SystemConfiguration
added a note to Poco::Util::ServerApplication documentation regarding creation of threads
added Poco::Net::IPAddress::broadcast() and Poco::Net::IPAddress::wildcard() to create broadcast (255.255.255.255) and wildcard (0.0.0.0) addresses.
fixed SF# 2916154: Poco::Net::IPAddress::isLoopback() only works for 127.0.0.1.
added build configuration for iPhone Simulator
GNU Make based build system provides new variables: POCO_HOST_BINDIR, POCO_HOST_BINPATH, POCO_HOST_LIBDIR, POCO_HOST_LIBPATH and POCO_TARGET_* equivalents.
Poco::Util::Application::initialize() and Poco::Util::Application::uninitialize() will now be called from within run(). This solves various issues with uninitialize() not being called, or being called inappropriately from the Application destructor. Please note that this change will break applications that use the Application class, but only call init() and not run().
added /startup option to specify startup mode for Windows services (automatic or manual)
fixed SF# 2967354: SecureSocketImpl shutdown/close problem
fixed SF# 3006340: LinearHashTable grows even if key already exists
fixed a particularly nasty Windows error handling issue that manifested itself on WinCE: WSAGetLastError() would be called after a std::string was created. The string creation could result in a heap operation which called a Windows API to allocate memory. This would reset the GetLastError() error code. Since WSAGetLastError() is just an alias for GetLastError(), the actual error code from the socket operation would be lost.
upgraded SQLite to 3.7.3
added —header-prefix option to PageCompiler
fixed SF# 3003875: SQLite data binding is broken
fixed SF# 2993988: Issue with multiple calls to open()/close() on File*Stream
fixed SF# 2990256: Poco::Net::HTMLForm and file uploads
fixed SF# 2969227: Poco::DateTimeParser bug
fixed SF# 2966698: Socket connect with timeout issue
fixed SF# 2981041: Bind NULL to a query (patch supplied)
fixed SF# 2961419: Poco::UTF8Encoding::convert() doesn't work properly in DEBUG mode
fixed SF# 2957068: Timeout value not picked up by proxy in Poco::Net::HTTPSClientSession
fixed NetSSL_OpenSSL test runner for Poco::Util::Application class changes
Poco::AbstractEvent, Poco::AbstractCache and related classes now accept a Mutex class as additional template argument. Poco::NullMutex can be used if no synchronization is desired.
Added Poco::AbstractEvent::empty() to check whether an event has registered delegates.
Poco::URI now correctly handles IPv6 addresses.
Added Poco::Nullable class template.
Added Poco::NullMutex, a no-op mutex to be used as template argument for template classes taking a mutex policy argument.
Poco::XML::XMLWriter: fixed a namespace handling issue that occured with startPrefixMapping() and endPrefixMapping()
Poco::Net::Context now allows for loading certificates and private keys from Poco::Crypto::X509Certificate objects and Poco::Crypto::RSAKey objects.
Poco::Crypto::RSAKey no longer uses temporary files for stream operations. Memory buffers are used instead.
fixed SF# 2957865: added Poco::UUID::tryParse()
All Zip classes now use Poco::File[Input|Output]Stream instead of std::[i|o]fstream. UTF-8 filenames will now be handled correctly on Windows.
fixed SF# 2902029: zlib flush support (Z_SYNC_FLUSH)
added Poco::TextBufferIterator class
fixed SF# 2977249: Use epoll instead select under Linux Poco::Net::Socket::select() and Poco::Net::Socket::poll() will use epoll under Linux if the Net library is compiled with -DPOCO_HAVE_FD_EPOLL. This is the default for the Linux build configuration (but not for the various build configurations targeting embedded Linux platforms).
fixed SF# 2941664: Memory leak in Poco::DeflatingStream with zero-length streams (also fixed some other potential, but unlikely, memory leaks)
fixed SF# 2946457: added Poco::Net::RejectCertificateHandler
fixed SF# 2946621: Poco::Path bug with POCO_WIN32_UTF8
fixed SF# 2929805: Environment::nodeId() does not work if no eth0 device exists
Poco::Environment::nodeId() no longer throws if no hardware ethernet address can be determined. It returns an all-zero address instead.
Added additional classification functions to Poco::Unicode class; made classification functions inline.
added Poco::Ascii class for ASCII character classification. Methods of the Ascii class are now used instead of the standard library functions (std::isspace(), etc.) due to possible inconsistent results or assertions when the standard library functions are used with character codes outside the ASCII range.
Poco::Net::MailMessage: fixed a bug in StringPartHandler that resulted in incorrect handling of non-ASCII data if char is signed.
Improved Poco::Net::SMTPClientSession compatibility with various mail servers when using AUTH_LOGIN authentication.
Added CRAM-SHA1 support to Poco::Net::SMTPClientSession
Poco::Net::SMTPClientSession now also supports login with AUTH PLAIN.
Added Poco::Net::SecureSMTPClientSession class, supporting STARTTLS for secure SMTP connections.
fixed an issue with SharedMemory on POSIX systems, where a shared memory region would be deleted despite the server flag set to true (see http://pocoproject.org/forum/viewtopic.php?f=12&t=3494).
PageCompiler: added a new page context directive, to allow passing custom context objects to the request handler.
fixed Poco::Net::StreamSocketImpl::sendBytes() for non-blocking sockets
added Poco::Net::DialogSocket::receiveRawBytes(), which should be used instead of receiveBytes() due to internal buffering by DialogSocket.
Poco::XML::DOMParser: FEATURE_WHITESPACE has been renamed to FEATURE_FILTER_WHITESPACE (which now matches the underlying URI) and is now handled correctly (previously we did the exact reverse thing)
added Poco::Util::AbstractConfiguration::remove() to remove a configuration property; added removeRaw() implementations to all implementations (contributions by Daniel Hobi and Alexey Shults).
fixed NetSSL_OpenSSL compilation error on Windows with OpenSSL 1.0
Added optional FIPS mode support to NetSSL_OpenSSL (contributed by Lior Okman). If OpenSSL has been configured and built with FIPS support, then FIPS support can be enabled by calling Poco::Crypto::OpenSSLInitializer::enableFIPSMode(true); or by setting the fips property in the OpenSSL configuration to true (see Poco::Net::SSLManager for details).
fixed SF# 3031530: Ping and possible no timeout
added Poco::Net::SocketReactor::onBusy(), called whenever at least one notification will be dispatched.
fixed SF# 3034863: Compiler warning in Net/IPAddress.h with poco 1.3.2
added support for CRAM-SHA1 authentication to Poco::Net::SMTPClientSession
Poco::format(): arguments can now be addressed by their index, e.g. %[2]d
Poco::Util::Timer::cancel() now accepts an optional boolean argument. If true is passed, cancel() waits until the task queue has been purged. Otherwise, it returns immediately and works asynchronously, as before.
Poco::Net::HTTPServerResponse::redirect() now accepts an optional additional argument to specify the HTTP status code for the redirection.
fixed a warning (BinaryReader.cpp) and error (ThreadLocal.cpp) in Foundation when compiling with Visual Studio 2010
fixed a wrong exception in Poco::Net::POP3ClientSession
Poco::Net::FTPClientSession and Poco::Net::SMTPClientSession now set the error code in exceptions they throw
fixed a potential race condition with terminating a Windows service based on Poco::Util::ServerApplication
fixed a bug in global build configuration file: explicitly setting POCO_CONFIG did not work on Solaris platforms, as it was always overridden by the automatically determined configuration.
Added support for MinGW cross builds on Linux.
Changed location of statically linked build products in the gmake-based build system. Statically linked executables are now in bin/$(OSNAME)/$(OSARCH)/static and no longer have the _s suffix
The POCO_VERSION macro now is in its own header file, "Poco/Version.h". It is no longer available through "Poco/Foundation.h".
added Poco::Net::HTTPCookie::escape() and Poco::Net::HTTPCookie::unescape().
fixed SF# 3021173: Poco::Thread (POSIX) returns uninitialised value for OS priority
fixed SF# 3040870: Poco::ThreadPool has no function to get assigned name
fixed SF# 3044303: Can't use own config file on Solaris & OSARCH_64BITS ignored
fixed SF# 2943896: Poco::AsyncChannel::log() blocks
fixed a bug in Poco::Util::WinRegistryKey::getInt(): The size variable passed to RegQueryValueExW() should be initialized to the size of the output buffer.
Added rudimentary support for compiling with Clang 2.0 (Xcode 4) on Mac OS X.
New build configurations for Mac OS X: Darwin32 and Darwin64 for explicit 32-bit and 64-bit builds. Note that the default Darwin build configuration will build 64-bit on Snow Leopard and 32-bit on Leopard, but will always place build products in Darwin/i386. The new Darwin32 and Darwin64 configurations will use the correct directories.
fixed SF# 3051598: Bug in URL encoding
Poco::ThreadPool::stopAll() (and thus also the destructor) will now wait for each pooled thread to terminate before returning. This fixes an issue with creating and orderly shutting down a thread pool in a plugin. Previously, a pooled thread in a thread pool created by a dynamically loaded library might still be running when the plugin's shared library was unloaded, resulting in Bad Things happening. This can now no longer happen. As a downside, a pooled thread that fails to finish will block stopAll() and the destructor forever.
NetSSL_OpenSSL: for a Poco::Net::SecureStreamSocket, available() now returns the number of bytes that are pending in the SSL buffer (SSL_pending()), not the actual socket buffer.
Added Poco::Net::HTTPClientSession::secure() to check for a secure connection.
Poco::Net::HTTPRequest::setHost() now does not include the port number in the Host header if it's either 80 or 443.
log messages can now optionally include source file path and line number
Poco::PatternFormatter can format source file path and line number (%U, %u)
logging macros (poco_information(), etc.) now use __LINE__ and __FILE__
new logging macros that incorporate Poco::format(): poco_information_f1(logger, format, arg) with up to 4 arguments
added Poco::Net::HTTPSession::attachSessionData() and Poco::Net::HTTPSession::sessionData() to attach arbitrary data to a HTTP session.
added additional constructors to zlib stream classes that allow passing a windowBits parameter to the underlying zlib library.
fixed a potential error handling issue in Poco::Net::SecureSocketImpl.
fixed SF# 3110272: Poco::Crypto::RSACipherImpl bug.
fixed SF# 3081677: Poco::Util::ConfigurationView's getRaw not retrieving xml attributes.
added basic support for Canonical XML and better pretty-printing support to Poco::XML::XMLWriter.
Poco::Util::AbstractConfiguration now supports events fired when changing or removing properties.
XML: added support for finding DOM nodes by XPath-like expressions. Only a very minimal subset of XPath is supported. See Poco::XML::Element::getNodeByPath(), Poco::XML::Element::getNodeByPathNS() and the same methods in Poco::XML::Document.
Poco::Timer: If the callback takes longer to execute than the timer interval, the callback function will not be called until the next proper interval. The number of skipped invocations since the last invocation will be recorded and can be obtained by the callback by calling skipped().
Poco::BinaryReader and Poco::BinaryWriter now support reading and writing std::vectors of the supported basic types. Also, strings can now be written in a different encoding (a Poco::TextEncoding can be optionally passed to the constructor).
Windows Embedded CE (5.0 and newer) is now a supported platform.
Poco::UUID::nil() and Poco::UUID::isNil() have been renamed to Poco::UUID::null() and Poco::UUID::isNull(), respectively, to avoid issues with Objective-C++ projects on Mac OS X and iOS where nil is a system-provided macro.
Crypto bugfixes: Poco::Crypto::RSACipherImpl now pads every block of data, not just the last (or last two).
Improved Crypto testsuite by adding new tests.
Added new Visual Studio project configurations: debug_static_mt and release_static_mt (linking with static runtime libraries). The existing configurations debug_static and release_static have been renamed to debug_static_md and release_static_md, respectively. The suffixes of the static libraries have also changed. The static_md configurations now build libraries with suffixes md[d], while the libraries built by the static_mt configurations have mt[d] suffixes.
Added Visual Studio project files for 64-bit builds.
Added Visual Studio 2010 project files.
Removed the use of local static objects in various methods due to their construction not being threadsafe (and thus leading to potential race conditions) on Windows/Visual C++.
Fixed some warning on 64-bit Windows builds.
The names of the Data connector libraries have changed. They are now named PocoDataMySQL, PocoDataODBC and PocoDataSQLite.
fixed SF# 3125498: Linux NetworkInterface::list() doesn't return IPv6 IPs
fixed SF# 3125457: IPv6 IPAddress tests are wrong
Added initialization functions for the NetSSL_OpenSSL and Crypto libraries. These should be called instead of relying on automatic initialization, implemented with static initializer objects, as this won't work with statically linked executables (where the linker won't include the static initializer object). The functions are Poco::Crypto::initializeCrypto(), Poco::Crypto::uninitializeCrypto(), Poco::Net::initializeSSL() and Poco::Net::uninitializeSSL(). Applications using Crypto and/or NetSSL should call these methods appropriately at program startup and shutdown. Note: In release 1.3.6, similar functions have been added to the Net library.

Incompatible Changes and Possible Transition Issues

The behavior of Poco::Timer has been changed for the case when the callback function takes longer to execute than the given timer interval. In this case, the missed intervals are counted and the next callback will be at the next proper interval.
Poco::XML::DOMParser: FEATURE_WHITESPACE has been renamed to FEATURE_FILTER_WHITESPACE (which now matches the underlying URI) and is now handled correctly (previously we did the exact reverse thing)
Poco::UUID::nil() and Poco::UUID::isNil() have been renamed to Poco::UUID::null() and Poco::UUID::isNull(), respectively, to avoid issues with Objective-C++ projects on Mac OS X and iOS where nil is a system-provided macro.
The names of the Data connector libraries have changed. They are now named PocoDataMySQL, PocoDataODBC and PocoDataSQLite.
The existing Visual Studio build configurations debug_static and release_static have been renamed to debug_static_md and release_static_md, respectively. Also, the suffixes of the static library names have changed to match usual conventions.
New static initialization functions for the Crypto and NetSSL_OpenSSL libraries have been added. These should be called instead of relying on automatic initialization, implemented with static initializer objects, as this won't work with statically linked executables (where the linker won't include the static initializer object). The functions are Poco::Crypto::initializeCrypto(), Poco::Crypto::uninitializeCrypto(), Poco::Net::initializeSSL() and Poco::Net::uninitializeSSL(). Applications using Crypto and/or NetSSL should call these methods appropriately at program startup and shutdown. Note: In release 1.3.6, similar functions have been added to the Net library.

Release 1.3.6p2

fixed SF# 2807527: Poco::Timer bug for long startInterval/periodic interval
fixed a bug similar to SF# 2807527 in Poco::Util::Timer.
fixed SF# 2795395: Constructor doesn't treat the params "key" and "iv"
fixed SF# 2804457: DateTime::checkLimit looks wrong
fixed SF# 2804546: DateTimeParser requires explicit RFC1123 format
added ReleaseArrayPolicy to Poco::SharedPtr
upgraded to SQLite 3.6.20
fixed SF# 2782709: Missing semicolons in "Logger.h" convenience
fixed SF# 2526407: DefaultStrategy.h ++it instead of it++ in a loop
fixed SF# 2502235: Poco STLPort patch
fixed SF# 2186643: Data::Statement::reset() not implemented in 1.3.3

fixed SF# 2791934: use of char_traits::copy in BufferedStreamBuf::underflow
fixed SF# 2807750: Support additional SQL types in SQLite
fixed documentation bugs in Timed/PriorityNotificationQueue
fixed SF# 2828401: Deadlock in SocketReactor/NotificationCenter (also fixes patch# 1956490) NotificationCenter now uses a std::vector internally instead of a std::list, and the mutex is no longer held while notifications are sent to observers.
fixed SF# 2835206: File_WIN32 not checking aganist INVALID_HANDLE_VALUE
fixed SF# 2841812: Posix ThreadImpl::sleepImpl throws exceptions on EINTR
fixed SF# 2839579: simple DoS for SSL TCPServer, HTTPS server No SSL handshake is performed during accept() - the handshake is delayed until sendBytes(), receiveBytes() or completeHandshake() is called for the first time. This also allows for better handshake and certificate validation when using nonblocking connections.
fixed SF# 2836049: Possible handle leak in FileStream If sync() fails, close() now simply set's the stream's bad bit. In any case, close() closes the file handle/descriptor.
fixed SF# 2814451: NetSSL: receiveBytes crashes if socket is closed
added a workaround for Vista service network initialization issue (an Windows service using the Net library running under Vista will crash in the call to WSAStartup() done in NetworkInitializer). Workaround is to call WSAStartup() in the application's main(). Automatic call to WSAStartup() in the Net library can now be disabled by compiling Net with -DPOCO_NET_NO_AUTOMATIC_WSASTARTUP. Also the new Poco::Net::initializeNetwork() and Poco::Net::uninitializeNetwork() functions can be used to call WSAStartup() and WSACleanup(), respectively, in a platform-independent way (on platforms other than Windows, these functions will simply do nothing).
added VCexpress build script support (contributed by Jolyon Wright)

fixed a documentation bug (wrong sample code) in Process::launch() documentation
added —header-output-dir option to PageCompiler
fixed SF# 2849144: Zip::Decompress notifications error
SAXParser has a new feature: "http://www.appinf.com/features/enable-partial-reads". See ParserEngine::setEnablePartialReads() for a description of what this does.
fixed SF# 2876179: MySQL Signed/Unsigned value bug
fixed SF# 2877970: possible bug in timer task
fixed SF# 2874104: wrong parsing empty http headers
fixed SF# 2860694: Incorrect return code from SecureStreamSocketImpl::sendBytes
fixed SF# 2849750: Possible bug with XMLWriter?
added MailMessage::encodeWord() to support RFC 2047 word encoded mail header fields when sending out mail containing non-ASCII characters.
fixed SF# 2890975: SMTPClientSession bug with 7BIT encoding
fixed an issue with retrieving the value of socket options on Windows 7. Before obtaining the value of a socket, we now initialize the variable receiving the socket option value to zero.
fixed SF# 2836141: Documentation errors
fixed SF# 2864232: Socket::select() does not detect closed sockets on windows
fixed SF# 2812143: Socket::select() should check socket descriptors...

fixed SF# 2896070: Poco::Net::Context with non-ASCII paths
added Unicode Surrogate support to Poco::UTF16Encoding. See Poco::TextEncoding::queryConvert() and Poco::TextEncoding::sequenceLength() for how this is implemented. Contributed by Philippe Cuvillier.
fixed SF# 2897650: [branch 1.3.6] Net.SocketAddress won't compile for CYGWIN
fixed SF# 2896161: Building on Windows fails when basedir has space in it
fixed SF# 2864380: Memory leak when using secure sockets
NetSSL_OpenSSL: the SSL/TLS session cache is now disabled by default and can be enabled per Context using Poco::Net::Context::enableSessionCache().
fixed SF# 2899039: Wrong DST handling in LocalDateTime
added Poco::RWLock::ScopedReadLock and Poco::RWLock::ScopedWriteLock (contributed by Marc Chevrier)
added Poco::Thread::TID type, as well as Poco::Thread::tid() and Poco::Thread::currentTid() to obtain the native thread handle/ID
added Zip file comment support
On Windows, Poco::SharedLibrary::load() now uses LoadLibraryEx instead of LoadLibrary and uses the LOAD_WITH_ALTERED_SEARCH_PATH if an absolute path is specified. This will add the directory containing the library to the search path for DLLs that the loaded library depends upon.
Mac OS X build settings now match those used by default Xcode projects, making linking the POCO libs to Xcode projects easier
Replaced use of std::valarray in Poco::Net::ICMPEventArgs with std::vector due to issues with std::valarray together with STDCXX debug mode on OS X

Release 1.3.5

Summary of Changes

fixed SF# 2779410: Poco::Data::ODBC::HandleException impovement
fixed wrong exception text for Poco::UnhandledException

added Poco::Crypto::X509Certificate::save()
fixed a bug in Poco::Zip::Decompress that results in wrong paths for extracted files
fixed a bug in Poco::Zip::ZipManipulator where the Zip file was opened in text format on Windows.
added Poco::Crypto::X509Certificate::issuedBy() to verify certificate chain.
added methods to extract the contents of specific fields from the subject and issuer distinguished names of a certificate.
fixed 0000089: Thread::sleep() on Linux is extremely inaccurate

Release 1.3.4

Summary of Changes

fixed SF# 2611804: PropertyFileConfiguration continuation lines
fixed SF# 2529788: ServerApplication::beDaemon() broken
fixed SF# 2445467: Bug in Thread_WIN32.cpp
Improved performance of HTTP Server by removing some string copy operations
fixed SF# 2310735: HTTPServer: Keep-Alive only works with send()
fixed appinf.com IP address in Net testsuite
fixed RFC-00188: NumberFormatter and float/double numbers
added —pidfile option to ServerApplication on Unix
fixed SF# 2499504: Bug in Win32_Thread when using from dll (fixed also for POSIX threads)
fixed SF# 2465794: HTTPServerRequestImpl memory leak
fixed SF# 2583934: Zip: No Unix permissions set
the NetSSL_OpenSSL library has been heavily refactored
added NumberFormatter::append*() and DateTimeFormatter::append() functions
use NumberFormatter::append() and DateTimeFormatter::append() instead of format() where it makes sense to gain some performance
added system.dateTime and system.pid to Poco::Util::SystemConfiguration
added %F format specifier (fractional seconds/microseconds) to DateTimeFormatter, DateTimeParser and PatternFormatter.
fixed SF# 2630476: Thread_POSIX::setStackSize() failure with g++ 4.3
fixed SF# 2679279: Handling of — option broken
added compile options to reduce memory footprint of statically linked applications by excluding various classes from automatically being linked. See the POCO_NO_* macros in Poco/Config.h.
fixed SF# 2644940: on Windows the COMPUTER-NAME and the HOSTNAME can be different
added DNS::hostName() function
added build configuration for iPhone (using Apple's SDK)
basic support for AIX 5.x/xlC 8
fixed a bug resulting in a badly formatted exception message with IOException thrown due to a socket-related error
fixed SF# 2644718: NetworkInterface name conflict in MinGW
added a missing #include to CryptoTransform.h
fixed SF# 2635377: HTTPServer::HTTPServer should take AutoPtr<HTTPServerParams>
replaced plain pointers with smart pointers in some interfaces
upgraded to sqlite 3.6.13
improved Data::SQLite error reporting
Poco::Glob now works with UTF-8 encoded strings and supports case-insensitive comparison. This also fixes SF# 1944831: Glob::glob on windows should be case insensitve
added Twitter client sample to Net library
Fixed SF# 2513643: Seg fault in Poco::UTF8::toLower on 64-bit Linux
Poco::Data::SessionPool: the janitor can be disabled by specifying a zero idle time.
added Poco::Data::SessionPool::customizeSession()
added support for different SQLite transaction modes (DEFERRED, IMMEDIATE, EXCLUSIVE)
fixed a few wrong #if POCO_HAVE_IPv6 in the Net library
added support for creating an initialized, but unconnected StreamSocket.
added File::isDevice()
added family() member function to SocketAddress,
Data::SQLite: added support for automatic retries if the database is locked
XMLConfiguration is now writable
fixed an IPv6 implementation for Windows bug in HostEntry
Timer class improvement: interval between callback is no longer influenced by the time needed to execute the callback.
added PriorityNotificationQueue and TimedNotificationQueue classes to Foundation. These are variants of the NotificationQueue class that support priority and timestamp-tagged notifications.
added Poco::Util::Timer class. This implements a timer that can schedule different tasks at different times, using only one thread.
the signatures of Poco::NotificationQueue and Poco::NotificationCenter member functions have been changed to accept a Poco::Notification::Ptr instead of Poco::Notification* to improve exception safety. This change should be transparent and fully backwards compatible. The signature of the methods returning a Poco::Notification* have not been changed for backwards compatibility. It is recommended, that any Notification* obtained should be immediately assigned to a Notification::Ptr.
SQLite::SessionImpl::isTransaction() now uses sqlite3_get_autocommit() to find out about the transaction state.
improved SQLite data type mapping
refactored Crypto library to make it independent from NetSSL_OpenSSL.
added support for RSA-MD5 digital signatures to Crypto library.
removed SSLInitializer from NetSSL library (now moved to Crypto library)
added build configs for static libraries to Crypto library
OpenSSL now depends on Crypto library (which makes more sense than vice versa, as it was before). Poco::Net::X509Certificate is now a subclass of Poco::Crypto::X509Certificate (adding the verify() member function) and the Poco::Net::SSLInitializer class was moved to Poco::Crypto::OpenSSLInitializer.
added build configs for static libraries to Zip
added batch mode to CppUnit::WinTestRunner. WinTestRunnerApp supports a batch mode, which runs the test using the standard text-based TestRunner from CppUnit. To enable batch mode, start the application with the "/b" or "/B" command line argument. Optionally, a path to a file where the test output will be written to may be given: "/b:<path>" or "/B:<path>". When run in batch mode, the exit code of the application will denote test success (0) or failure (1).
testsuites now also work for static builds on Windows
The IPv6 support for Windows now basically works (Net library compiled with POCO_HAVE_IPv6)
fixed a potential error when shutting down openssl in a statically linked application
added static build configs to Data library
added Poco::AtomicCounter class, which uses OS-specific APIs for atomic (thread-safe) manipulation of counter values.
Poco::RefCountedObject and Poco::SharedPtr now use Poco::AtomicCounter for reference counting
fixed SF# 2765569: LoadConfiguration failing from current directory

Incompatible Changes and Possible Transition Issues

Some methods that have previously taken a plain pointer (to a reference counted object) as argument now take a Poco::AutoPtr instead. This shouldn't cause any problems for properly written code. Examples are Poco::NotificationCenter, Poco::NotificationQueue and Poco::Net::HTTPServer.
Poco::Glob now works with and assumes UTF-8 encoded strings.
Poco::Timer: the interval between callbacks is no longer influenced by the time needed to execute the callback.
The Crypto and NetSSL_OpenSSL libraries have been refactored. NetSSL_OpenSSL now depends on the Crypto library (previously, it was vice versa).

Release 1.3.3

Summary of Changes

Threads now have optional user-settable stack size (if the OS supports that feature)
Events now support simplified delegate syntax based on delegate function template. See Poco::AbstractEvent documentation for new syntax.
Cache supports new access expire strategy.
Upgraded to SQLite 3.6.2
Upgraded to PCRE 7.8
added HttpOnly support to Poco::Net::HTTPCookie
NetworkInterface now has displayName() member (useful only on Windows)
Poco::Util::WinRegistryKey now has a read-only mode
Poco::Util::WinRegistryKey::deleteKey() can now recursively delete registry keys
Poco::File::created() now returns 0 if the creation date/time is not known, as it's the case on most Unix platforms (including Linux). On FreeBSD and Mac OS X, it returns the real creation time.
Time interval based log file rotation (Poco::FileChannel) now works correctly. Since there's no reliable and portable way to find out the creation date of a file (Windows has the tunneling "feature", most Unixes don't provide the creation date), the creation/rotation date of the log file is written into the log file as the first line.
added Environment::nodeId() for obtaining the Ethernet address of the system (this is now also used by UUIDGenerator - the corresponding code from UUIDGenerator was moved into Environment)
added a release policy argument to SharedPtr template
Socket::select() will no longer throw an InvalidArgumentException on Windows when called with no sockets at all. If all three socket sets are empty, Socket::select() will return 0 immediately.
SocketReactor::run() now catches exceptions and reports them via the ErrorHandler.
SocketReactor has a new IdleNotification, which will be posted when the SocketReactor has no sockets to handle.
added referenceCount() method to Poco::SharedPtr.
POCO now builds with GCC 4.3 (but there are some stupid warnings: "suggest parentheses around && within ||".

Incompatible Changes and Possible Transition Issues

The (now deprecated) Poco::HashFunction class template has been changed in an incompatible way. The member function formerly named hash() is now the function call operator. If you have defined your own HashFunction classes, you have to update your code. Sorry for the inconvenience.

On Windows, POCO now builds with Unicode/UTF-8 support (POCO_WIN32_UTF8) enabled by default. If you need the previous (1.2) behavior, remove the corresponding #define from Poco/Config.h
