      Always do backups in time ;)
      you are in the worst situation, that can happen…

        A new version of zxing-cpp (zebra crossing QR code library), has been released.

        https://github.com/glassechidna/zxing-cpp/pull/57

        *   Installation working as a configuration package
        *   Fix source listing to not use GLOB per CMake recommendation. Files
            are listed explicitly in source_files.cmake so that if file listing
            changes, CMake can detect it and regenerate as needed.
        *   Added debug postfix for libs for side-by-side installation of different
            build variants (libzxing.lib and libzxing-debug.lib on Windows)
        
        Notes:
        
        *  Proper versioning is not being done in the installation config package. If a version is known, it should be added.
        *  I had to comment out the windows-specific stuff (core/win32) because it caused compiler issues in Windows SDK headers.

                First block with error message is block : 432000 (const int nForkFour = 432000;)

                ERROR: matches claimed amount, CheckProofOfWork()
                

                All blocks after that have the message, checked up to block 1877425

                    The first time it does preliminary checks it says hash is different to what it then goes straight through CheckProofOfWork()…

                    then :

                      Neoscrypt is little endian, may be a byte swap will do the trick.

                      Was fighting with that for p2pool already.

                      Here is the python code snippet to get it running in p2pool.

                       getwork._swap4(pack.IntType(256).pack(x['previous_block'])).encode('hex'), # prevhash
                              x['coinb1'].encode('hex'), # coinb1
                              x['coinb2'].encode('hex'), # coinb2
                              [pack.IntType(256).pack(s).encode('hex') for s in x['merkle_link']['branch']], # merkle_branch
                              getwork._swap4(pack.IntType(32).pack(x['version'])).encode('hex'), # version
                              getwork._swap4(pack.IntType(32).pack(x['bits'].bits)).encode('hex'), # nbits
                              getwork._swap4(pack.IntType(32).pack(x['timestamp'])).encode('hex'), # ntime
                      

                      Definition of swap4:

                      def _swap4(s):
                      if len(s) % 4:
                          raise ValueError()
                      return ''.join(s[x:x+4][::-1] for x in xrange(0, len(s), 4))
                      

                      Not sure, how to realize that in C++

                          try --with-gui=qt5

                          qt4 support is broken in 0.9x, but tested first and then selected by configure.

                            I am compiling with the standard switches, exactly the same as before, except now qrcodes=no

                              Then check, if you have a qrcodedialog in the …/qt/forms directory.

                                Fixed.

                                I’ve git cloned from head. There is nothing missing and I haven’t done anything to it except add my build.sh and change my compile to qrcodes=no to get it compile…

                                  Bitcoin 0.9.x Backports 2

                                  #68

                                  https://github.com/bitcoin/bitcoin/commit/0a94661e8db94e84ecbf1ea45a51fb3c7fb77283

                                  Disable SSLv3 (in favor of TLS) for the RPC client and server.

                                  TLS is subject to downgrade attacks when SSLv3 is available, and
                                  SSLv3 has vulnerabilities.

                                  The popular solution is to disable SSLv3. On the web this breaks
                                  some tiny number of very old clients. While Bitcoin RPC shouldn’t
                                  be exposed to the open Internet, it also shouldn’t be exposed to
                                  really old SSL implementations, so it shouldn’t be a major issue
                                  for us to disable SSLv3.

                                  There is more information on the downgrade attacks and disabling
                                  SSLv3 at https://disablessl3.com/ .

                                    Consensus: guard against openssl’s new strict DER checks

                                     0.9 (#106) 
                                    

                                    New versions of OpenSSL will reject non-canonical DER signatures. However,
                                    it’ll happily decode them. Decode then re-encode before verification in order
                                    to ensure that it is properly consumed.

                                            rpcdump.cpp

                                            file << strprintf("# Wallet dump created by Bitcoin %s (%s)\n", CLIENT_BUILD, CLIENT_DATE);
                                            

                                            Todo / Test : Compare with @ghostlanders FTC 0.8.4 version?

                                            Here what I found today, don’t know if it’s a known issue ?
                                            https://github.com/FeatherCoin/Feathercoin/issues/236

                                            Basicly dumpwallet, only dump header, the content of the wallet doesn’t show.
