* net: Consistent checksum handling
In principle, the checksums of P2P packets are simply 4-byte blobs which
are the first four bytes of SHA256(SHA256(payload)).
Currently they are handled as little-endian 32-bit integers half of the
time, as blobs the other half, sometimes copying the one to the other,
resulting in somewhat confused code.
This PR changes the handling to be consistent both at packet creation
and receiving, making it (I think) easier to understand.
* net: Hardcode protocol sizes and use fixed-size types
The P2P network uses a fixed protocol, these sizes shouldn't change
based on what happens to be the architecture.
* Only store and connect to NODE_NETWORK nodes
* Keep addrman's nService bits consistent with outbound observations
* Verify that outbound connections have expected services
* Don't require services in -addnode
* Introduce enum ServiceFlags for service flags
* Introduce REQUIRED_SERVICES constant
Followup for the recent winner_block PR (#1028) and name confusion discovered during code review.
"Mostly" because also:
- CMasternodeBlockPayees::GetPayee -> CMasternodeBlockPayees::GetBestPayee which describes what this function is actually doing a bit better imo;
- fixing constructor CMasternodePaymentVote empty constructor
* store vote hashes in CMasternodePayee and use them in CMasternodePayments::Sync
* Request low data payment blocks in batches directly from some node instead of/after preliminary Sync.
* remove nVotes
- mn hash compatibility with 70103
- ignore some requests while syncing
- fix locking/initializing in sync
- do not ban for old mnw
- split budget/governance messages/invs
487674f Governance object/vote syncing fixes
- disable fCached values
- use two maps for storing votes, by hash and parent-hash/type
- disable part of flatdb.dump (still overwriting)
- fixed govobj/votes relay and sync
15821fe various fixes
- Added const where possible
- Uncommented sync block
- Protocol min 70201
- Fixed bug which flags invalid votes incorrectly
- Formatting
aa8fdd7 fix curly braces
d8e39b1 Fix GetTypeHash bug
- Should not collide based on the outcome
732a8a3 fixed mismatched index for vote map
If we want to be compatible to 12.0 on network layer we need them back in ppszTypeName[] to keep inv type consistent (allNetMessageTypes[] should not have them, we shouldn't accept non-implmented messages)
- Avoids string typos (by making the compiler check)
- Makes it easier to grep for handling/generation of a certain message type
- Refer directly to documentation by following the symbol in IDE
- Move list of valid message types to protocol.cpp:
protocol.cpp is a more appropriate place for this, and having
the array there makes it easier to keep things consistent.

- add missing strings and make inv strings a bit more consistent (imo)
- remove "unknown" types that were used to prevent errors thrown at user with old wallet,
just log such errors in debug mode for "net" category. Should also make behaviour of functions
relaing on CInv::IsKnownType() more adequate
(and it doesn't make sense to warn users by throwing errors at them in such situations anyway I guess)
- Added commands for using budgets "mnbudget" and "mnfinalbudget"
- Supports 100% decentralized budget control and view-only site with json meta data object
- Removed of reference node and replaced with decentralized quorums that pick the masternodes who get paid each block.
- Made a budgeting system, where masternodes can vote on individual budgets and the data is stored perminently on each clients computer
- Ensures ports remain open and client are responsive to IX requests.
- Completely 100% decentralized. This farms out the work of checking the masternode network to the masternode network. 1% of the network is determistically selected to check another 1% of the network each block. It takes six separate checks to deactivate a node, thus making it tamper proof.
- Nodes are kept in the masternode list if they fail enough PoSe checks to deactivate. They will continue to be checked until the operator fixes them. However they will not be paid while they're failing checks.
- Remove spurious `pchCommand[1] = 1` in CMessageHeader()
- Make sure that pchCommand is zero-padded if length is shorter than
COMMAND_SIZE
- Use strnlen to determine length of pcmCommand in GetCommand
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.
After the tinyformat switch sprintf() family functions support passing
actual std::string objects.
Remove unnecessary c_str calls (236 of them) in logging and formatting.
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.
The new class is accessed via the Params() method and holds
most things that vary between main, test and regtest networks.
The regtest mode has two purposes, one is to run the
bitcoind/bitcoinj comparison tool which compares two separate
implementations of the Bitcoin protocol looking for divergence.
The other is that when run, you get a local node which can mine
a single block instantly, which is highly convenient for testing
apps during development as there's no need to wait 10 minutes for
a block on the testnet.
Added explicit include of main.h in init.cpp, changed include of init.h to include of main.h in net.cpp.
Added function registration for net.cpp in init.cpp's network initialization.
Removed protocol.cpp's dependency on main.h.
TODO: Remove main.h include in net.cpp.
