+
+
+    Overview
+    --------
+
+    GpgME++ is a C++ wrapper (or C++ bindings) for the GnuPG project's
+    gpgme (GnuPG Made Easy) library, version 0.4.4 and later.
+
+    It is fairly complete, with some minor things still missing (in
+    particular, the key edit interface). It is mostly tested using
+    external event loops, for which its design is optimised.
+
+    The design principles of this library are as follows:
+
+    1. A value-based interface (most clases are implicitly shared)
+    2. Callbacks are replaced by C++ interfaces (classes with only
+       abstract methods).
+    3. No exceptions are thrown
+    4. There is (as yet) no explicit support for multi-threaded use
+       (other than what gpgme itself provides; most notably the
+       refcounting for implicit sharing is not thread-safe)
+    5. To avoid binary incompatible interface changes, we make
+       extensive use of the d-pointer pattern and avoid virtual
+       methods; any polymorphism present is already provided by gpgme
+       itself, anyway (see e.g. Data). A notable exception of the
+       no-virtuals rule is the use of abstract classes to cover
+       C-callbacks.
+
+    The authors hope that once there are more users of this library,
+    the GnuPG project will include it as the official C++ binding for
+    gpgme. Currently, this is not the case, since it was felt that C++
+    bindings can be provided with different design decisions, and that
+    it is not clear that the decisions made for GpgME++ are broad
+    enough to be universally applicable (e.g. a pivotal design
+    decision was to not use exceptions to wrap gpgme_error_t).
+
+    GpgME++ depends on gpgme, which in turn depends on libgpg-error, both
+    of which must be installed correctly before GpgME++ is to be
+    built. Furthermore, GpgME++ should be recompiled if the underlying
+    gpgme is changed. This is to allow closer integration and to
+    abstract away possible interface changes. Therefore, once this
+    libray becomes stable, we intend to follow gpgme's versioning.
+
+    Currently, we use the KDE CVS repository to develop our code,
+    basically because GpgME++ is used in KMail and Kleopatra. However,
+    the library is in no way dependant on KDE or Qt libraries, and you
+    are free to use it in your own projects, provided you follow the
+    license. If you _do_ want to use GpgME++ in Qt/KDE applications,
+    have a look at QGpgME, which provides integration with QEventLoop
+    and some Qt datatypes (e.g. QByteArray).
+
+
+    Mailing List
+    ------------
+
+    Discussion of this library and questions regarding it's use and
+    design should happen on gpa-dev@gnupg.org or gnupg-devel@gnupg.org.
+
+
+    License
+    -------
+
+    This library is licensed under the GNU General Public License
+    (GPL), just as gpgme is. We feel that using a different license
+    than the one gpgme itself uses doesn't make sense. OTOH, we shall
+    relicense this library to the GNU Lesser General Public License
+    (LGPL) should gpgme itself be made available under this license at
+    any time in the future.

+      \brief Abstract base class for gpgme's external event loop support
+
+      This class does most of the work involved with hooking GpgME++
+      up with external event loops, such as the GTK or TQt ones.
+
+      It actually provides two interfaces: An interface to the gpgme
+      IO Callback handling and one for gpgme events. The IO Callback
+      interface consists of the three methods \c actOn(), \c
+      registerWatcher() and \c unregisterWatcher(). The event
+      interface consists of the three methods \c nextTrustItemEvent(),
+      \c nextKeyEvent() and \c operationDoneEvent().
+
+      \sect General Usage
+
+      \c EventLoopInteractor is designed to be used as a
+      singleton. However, in order to make any use of it, you have to
+      subclass it and reimplement it's pure virtual methods (see
+      below). We suggest you keep the constructor protected and
+      provide a static \c instance() method that returns the single
+      instance. Alternatively, you can create an instance on the
+      stack, e.g. in \c main().
+
+      If you want \c EventLoopInteractor to manage a particular \c
+      Context, just call \c manage() on the \c Context. OTOH, if you
+      want to disable IO callbacks for a \c Context, use \c unmanage().
+
+      \sect IO Callback Interface
+
+      One part of this interface is represented by \c
+      registerWatcher() and \c unregisterWatcher(), both of which are
+      pure virtual. \c registerWatcher() should do anything necessary
+      to hook up watching of file descriptor \c fd for reading (\c dir
+      = \c Read) or writing (\c dir = Write) to the event loop you use
+      and return a tag identifying that particular watching process
+      uniquely. This could be the index into an array of objects you
+      use for that purpose or the address of such an object. E.g. in
+      TQt, you'd essentially just create a new \c TQSocketNotifier:
+
+      \verbatim
+      void * registerWatcher( int fd, Direction dir ) {
+        return new TQSocketNotifier( fd, dir == Read ? TQSocketNotifier::Read : TQSocketNotifier::Write );
+	// misses connecting to the activated() signal...
+      }
+      \endverbatim
+
+      which uses the address of the created object as unique tag. The
+      tag returned by \c registerWatcher is stored by \c
+      EventLoopInteractor and passed as argument to \c
+      unregisterWatcher(). So, in the picture above, you'd implement \c
+      unregisterWatcher() like this:
+
+      \verbatim
+      void unregisterWatcher( void * tag ) {
+        delete static_cast<TQSocketNotifier*>( tag );
+      }
+      \endverbatim
+
+      The other part of the IO callback interface is \c actOn(), which
+      you should call if you receive notification from your event loop
+      about activity on file descriptor \c fd in direction \c dir. In
+      the picture above, you'd call this from the slot connected to
+      the socket notifier's \c activated() signal.
+
+      \note \c registerWatcher() as well as \c unregisterWatcher() may
+      be called from within \c actOn(), so be careful with
+      e.g. locking in threaded environments and keep in mind that the
+      object you used to find the \c fd and \c dir fo the \c actOn()
+      call might be deleted when \c actOn() returns!
+
+      \sect Event Handler Interface

+
+	This patch has gotten a bit large... mmh.  The main thing that
+	happens here is that error values are now not determined in the
+	operation function after gpgme_wait completed, but in the status
+	handler when EOF is received.  It should always be the case that
+	either an error is flagged or EOF is received, so that after a
+	gpgme_wait you should never have the situation that no error is
+	flagged and EOF is not received.  One problem is that the engine
+	status handlers don't have access to the context, a horrible
+	kludge works around this for now.  All errors that happen during a
+	pending operation should be catched and reported in ctx->error,
+	including out-of-core and cancellation.  This rounds up neatly a
+	couple of loose ends, and makes it possible to pass up any errors
+	in the communication with the backend as well.  As a bonus, there
+	will be a function to access gpgme->wait, so that the operations
+	can truly be implemented with their _start function.

+	 Suppose there is a byte with all zeros.  Any carry bits
+	 propagating from its left will fall into the hole at its
+	 least significant bit and stop.  Since there will be no
+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.  If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-30 is set, there will be a carry
+	 into bit 31, so all of the hole bits will be changed.
+
+	 The one misfire occurs when bits 24-30 are clear and bit
+	 31 is set; in this case, the hole at bit 31 is not
+	 changed.  If we had access to the processor carry flag,
+	 we could close this loophole by putting the fourth hole
+	 at bit 32!
+
+	 So it ignores everything except 128's, when they're aligned
+	 properly.
+
+	 3) But wait!  Aren't we looking for C, not zero?
+	 Good point.  So what we do is XOR LONGWORD with a longword,
+	 each of whose bytes is C.  This turns each byte that is C
+	 into a zero.  */
