We need to bump the `zcashd` protocol version because the new rules are
not compatible with existing rules followed by 170015 nodes, but we
_also_ need to ensure we can still bump it again once we set the testnet
reactivation height (changing node network behaviour again). This commit
also enables RPC tests to run (because previously the nodes considered
each other to be too old for NU5 to be active, and were disconnecting).
This adds the double-hash message variant. The extra hash field is set
to null for block message types, and to all-ones for MSG_TX (to match
the legacy authHash value used for pre-v5 transactions in the Merkle
tree).
Lets nodes advertise that they offer bloom filter support explicitly.
The protocol version bump allows SPV nodes to assume that NODE_BLOOM is
set if NODE_NETWORK is set for pre-170004 nodes.
Also adds an option to turn bloom filter support off for nodes which
advertise a version number >= 170004. Nodes attempting to use bloom
filters on such protocol versions are banned, and a later upgade
should drop nodes of an older version which attempt to use bloom
filters.
Much code stolen from Peter Todd.
Zcash: Implements Zcash equivalent of BIP 111; deploys with Overwinter
Many changes:
* Do not use 'getblocks', but 'getheaders', and use it to build a headers tree.
* Blocks are fetched in parallel from all available outbound peers, using a
limited moving window. When one peer stalls the movement of the window, it is
disconnected.
* No more orphan blocks. At all. We only ever request a block for which we have
verified the headers, and store it to disk immediately. This means that a
disk-fill attack would require PoW.
* Require protocol version 31800 for every peer (released in december 2010).
* No more syncnode (we sync from everyone we can, though limited to 1 during
initial *headers* sync).
* Introduce some extra named constants, comments and asserts.
- ensures a consistent usage in header files
- also add a blank line after the copyright header where missing
- also remove orphan new-lines at the end of some files
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
INIT_PROTO_VERSION is the initial version, after a succesful version/verack it is increased to a negotiated version.
MIN_PEER_PROTO_VERSION could be a different value to disconnect from peers older than a specified version.
- add version information to bitcoin-qt.rc, which is displayed on Windows, when looking in the executable properties and selecting "Details"
- introduce a new clientversion.h (used in bitcoin-qt.rc to generate
version information), which takes only the version defines from
version.h and is included in it (to allow usage with the windres rc-file
compiler)
- move #define STRINGIFY(s) #s into clientversion.h as that is used in
bitcoin-qt.rc and rename to DO_STRINGIZE(X)
- add #define STRINGIZE(X) DO_STRINGIZE(X), which is needed to convert the
version defines into a version string in the rc-file
- this ensures we only need to update 1 file and have bitcoin-qt.exe
version information
