Using this modification it should be relatively easy to, at a later
time, listen on multiple addresses (even Unix domain sockets should be
possible).

The RPC server now listens for, and handles, incoming connections on
both IPv4 as well as IPv6.
If available (and usable) it uses a dual IPv4/IPv6 socket on systems
that support it (e.g. Linux and BSDs) and falls back to separate
IPv4/IPv6 sockets on systems that don't (e.g. Windows).

This allows more flexibility in the RPC code, e.g. making it easier to
handle multiple simultaneous connections later on.
Currently asynchronous I/O is only used to listen for and accept
incoming connections. Asynchronous reading/writing is more involved.

This introduces internal types:
* CKeyID: reference (hash160) of a key
* CScriptID: reference (hash160) of a script
* CTxDestination: a boost::variant of the former two
CBitcoinAddress is retrofitted to be a Base58 encoding of a
CTxDestination. This allows all internal code to only use the
internal types, and only have RPC and GUI depend on the base58 code.
Furthermore, the header dependencies are a lot saner now. base58.h is
at the top (right below rpc and gui) instead of at the bottom. For the
rest: wallet -> script -> keystore -> key. Only keystore still requires
a forward declaration of CScript. Solving that would require splitting
script into two layers.
- Signals now go directly from the core to WalletModel/ClientModel.
- WalletModel subscribes to signals on CWallet: Prepares for multi-wallet support, by no longer assuming an implicit global wallet.
- Gets rid of noui.cpp, the few lines that were left are merged into init.cpp
- Rename wxXXX message flags to MF_XXX, to make them UI indifferent.
- ThreadSafeMessageBox no longer returns the value `4` which was never used, converted to void.
Change internal HTTP JSON-RPC server from single-threaded to
thread-per-connection model. The IP filter list is applied prior to starting
the thread, which then processes the RPC.
A mutex covers the entire RPC operation, because not all RPC operations are
thread-safe.
[minor modifications by jgarzik, to make change upstream-ready]
This is an Object specifying how to decompose specific elements.
Currently supported:
- "tx": "no", "hash", "hex", "obj"
- "script": "no", "hex", "asm"
Previously trying to create a multisig address that required less than
one signature would output something like the following:
"wrong number of keys(got 1, need at least 0)"
Works for wallet transactions, memory-pool transaction and block chain
transactions.
Available for all:
* txid
* version
* locktime
* size
* coinbase/inputs/outputs
* confirmations
Available only for wallet transactions:
* amount
* fee
* details
* blockindex
Available for wallet transactions and block chain transactions:
* blockhash
* time
This commit removes the dependency of serialize.h on PROTOCOL_VERSION,
and makes this parameter required instead of implicit. This is much saner,
as it makes the places where changing a version number can have an
influence obvious.
Where possible, use boost::filesystem::path instead of std::string or
char* for filenames. This avoids a lot of manual string tinkering, in
favor of path::operator/.
GetDataDir is also reworked significantly, it now only keeps two cached
directory names (the network-specific data dir, and the root data dir),
which are decided through a parameter instead of pre-initialized global
variables.
Finally, remove the "upgrade from 0.1.5" case where a debug.log in the
current directory has to be removed.
Do not automatically change the wallet format unless the user takes an
explicit action that implies an upgrade (encrypting, for now), or uses
-walletupgrade.
-walletupgrade optionally takes an integer argument: the client version
up to which upgrading is allowed. Without an argument, it is upgraded
to latest supported version. If an argument to -walletupgrade is
provided at the time the wallet is created, the new wallet will initially
not use features beyond that version.
Third, the current wallet version number is reported in getinfo.
2^31 milliseconds is only about 25 days. Also clamps Sleep() to 10 years,
because it currently sleeps for 0 seconds when the sleep time would cross
2^31 seconds since the epoch. Hopefully boost will be fixed by 2028.
- Add "size" and "bits"
- Rename "blockcount" to "height"
- Rename "hashprevious" and "hashnext" to "previousblockhash" and "nextblockhash" (respectively)
* Fix sign error in calculation of seconds to sleep
* Do not mix GetTime() (seconds) and Sleep() (milliseconds)
* Do not sleep forever if walletlock() is called
* Do locking within critical section
Help users avoid insecure configurations a bit by recommending a
secure RPC password and increasing the incorrect password delay.
This may open up a RPC DOS for users with exposed RPC ports and
short passwords. Since users shouldn't have exposed RPC ports OR
short passwords, the DOS risk is preferable to the compromise
risk.
Also logs the client IP address for incorrect attempts.
base58-encoding of full/compressed public keys needs more thought; it probably makes sense to define a base58 encoding that includes a version byte and a checksum. So just support hex and bitcoin-address encodings for now.
This turns on most gcc warnings, and removes some unused variables and other code that triggers warnings.
Exceptions are:
-Wno-sign-compare : triggered by lots of comparisons of signed integer to foo.size(), which is unsigned.
-Wno-char-subscripts : triggered by the convert-to-hex functions (I may fix this in a future commit).
This patch enabled compressed pubkeys when -compressedpubkeys is passed.
These are 33 bytes instead of 65, and require only marginally more CPU
power when verifying. Compressed pubkeys have a different corresponding
address, so it is determined at generation. When -compressedpubkeys is
given, all newly generated addresses will use a compressed key, while
older/other addresses keep using normal keys. Unpatched clients will
relay and verify these transactions.
so it takes a flag for how to interpret OP_EVAL.
Also increased IsStandard size of scriptSigs to 500 bytes, so
a 3-of-3 multisig transaction IsStandard.
OP_EVAL is a new opcode that evaluates an item on the stack as a script.
It enables a new type of bitcoin address that needs an arbitrarily
complex script to redeem.
Introduces two new RPC calls:
* dumpprivkey: retrieve the private key corresponding to an address
* importprivkey: add a private key to your wallet
The private key format is analoguous to the address format. It is
a 51-character base58-encoded string, that includes a version number
and a checksum.
Includes patch by mhanne:
* add optional account parameter for importprivkey, if omitted use default
SecureString is identical to std::string except with secure_allocator
substituting for std::allocator. This makes casting between them
impossible, so converting between the two at API boundaries requires
calling ::c_str() for now.
This leads to the bitcoin core being shut down while the UI is accessing it, and generally results in a segmentation fault or crash. In case it is desirable to make it possible to shutdown the GUI from its RPC server, we'll need to implement a signal for it. For the mean time, this is a safe stopgap.
This RPC is exactly identical to getblockcount. This duplication
dates back to commit 22f721dbf2 when
Satoshi created the RPC interface.
There's no need to have both, so we standardize on "count" which
matches the naming convention in getconnectioncount.
Following the tradition established with previously deprecated APIs,
getblocknumber continues to work, but it's not listed in the help
system.
getmemorypool [data]
If [data] is not specified, returns data needed to construct a block to work on:
"version" : block version
"previousblockhash" : hash of current highest block
"transactions" : contents of non-coinbase transactions that should be included in the next block
"coinbasevalue" : maximum allowable input to coinbase transaction, including the generation award and transaction fees
"time" : timestamp appropriate for next block
"bits" : compressed target of next block
If [data] is specified, tries to solve the block and returns true if it was successful.
Instead of encoding the public key inside the signature string, use
key recovery to do verification. This allows 88-character base64-encoded
signature strings instead of 188-character ones.
This replaces the openssl-based base64 encoder and decoder with a more
efficient internal one. Tested against the rfc4648 test vectors.
Decoder is based on JoelKatz' version.
Makefiles now build bitcoind only.
qmake/make in top-level directory is used to build Bitcoin QT
Deleted almost all #ifdef GUI from the code (left one possibly controversial one)
Deleted xpm/ files.
