* Re-introduce alert functionality (#1470)Ross Nicoll2018-09-191-0/+7
| | | Re-introduce alert functionality removed from Bitcoin upstream
* Increment MIT Licence copyright header year on files modified in 2016isle29832016-12-311-1/+1

* Minor change to comment above new NODE_WITNESS service flag to keep it ↵Greg Walker2016-11-221-1/+1
| | | | consitent with existing comment structure. Helps with readability.
* Get rid of nType and nVersionPieter Wuille2016-11-071-6/+7
| | | | | | | | | | | Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.
* protocol.h: Make enums in GetDataMsg concrete valuesWladimir J. van der Laan2016-10-051-8/+12
| | | | | | | | | This concretizes the numbers and adds a comment to make it clear that these numbers are fixed by the protocol, and may avoid people forgetting to claim numbers in the future (e.g. issue #8500). Also gets rid of a weird unused `MSG_TYPE_MAX` in the middle of the enumeration (thanks @paveljanik for noticing).
* protocol.h: Move MESSAGE_START_SIZE into CMessageHeaderWladimir J. van der Laan2016-10-041-13/+10
| | | | | Also move the enum to the top, and remove a deceptive TODO comment.
* net: Hardcode protocol sizes and use fixed-size typesWladimir J. van der Laan2016-09-281-3/+3
| | | | | The P2P network uses a fixed protocol, these sizes shouldn't change based on what happens to be the architecture.
* net: Consistent checksum handlingWladimir J. van der Laan2016-09-281-2/+2
| | | | | | | | | | | | 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: narrow include scope after moving to netaddressCory Fields2016-07-311-1/+1
| | | | | Net functionality is no longer needed for CAddress/CAddrman/etc. now that CNetAddr/CService/CSubNet are dumb storage classes.

* Implement "feefilter" P2P message.Alex Morcos2016-03-211-1/+6
| | | | The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.

* | net: Add and document network messages in protocol.hWladimir J. van der Laan2015-12-101-0/+159
|/ | | | | | | | | - 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 NODE_BLOOM service bit and bump protocol versionMatt Corallo2015-09-051-0/+4
| | | | | | | | | | | | | | | | 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-70011 nodes. Also adds an option to turn bloom filter support off for nodes which advertise a version number >= 70011. 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. Implements BIP 111
* nLastTry is only used for addrman entriesPieter Wuille2015-04-191-3/+0
| | | | No need to define it for every CAddress, as it's memory only anyway.
* Add a NODE_GETUTXO service bit and document NODE_NETWORK.Mike Hearn2015-03-211-0/+7
| | | | Stop translating the NODE_* names as they are technical and cannot be translated.
* make CMessageHeader a dumb storage classCory Fields2015-02-251-3/+5

* rework overhauled serialization methods to non-staticKamil Domanski2014-08-311-18/+18
| | | | | | | Thanks to Pieter Wuille for most of the work on this commit. I did not fixup the overhaul commit, because a rebase conflicted with "remove fields of ser_streamplaceholder". I prefer not to risk making a mistake while resolving it.
* overhaul serialization codeKamil Domanski2014-08-311-23/+38
| | | | | | | | | | | | | | | | | | | | | The implementation of each class' serialization/deserialization is no longer passed within a macro. The implementation now lies within a template of form: template <typename T, typename Stream, typename Operation> inline static size_t SerializationOp(T thisPtr, Stream& s, Operation ser_action, int nType, int nVersion) { size_t nSerSize = 0; /* CODE */ return nSerSize; } In cases when codepath should depend on whether or not we are just deserializing (old fGetSize, fWrite, fRead flags) an additional clause can be used: bool fRead = boost::is_same<Operation, CSerActionUnserialize>(); The IMPLEMENT_SERIALIZE macro will now be a freestanding clause added within class' body (similiar to Qt's Q_OBJECT) to implement GetSerializeSize, Serialize and Unserialize. These are now wrappers around the "SerializationOp" template.

Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

* Introduce a CChainParameters singleton class and regtest mode.Mike Hearn2013-06-191-10/+1
| | | | | | | | | | | | | 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.
