After pull #4288, RPC messages indicating errors have a Content-Length unrelated
to their actual contents, rendering bitcoin-cli and curl unable to decode the
reply.
This patch sets the Content-Length field based on the actual content returned.
Additionally, pull #4288 clobbered the error descriptions provided in
ErrorReply, which bitcoin-cli relies upon; this patch moves #4288 http-error
descriptions to an HTTPError method, allowing HTTPReply to pass content on
unchanged.
The original comment forgets to account for the script push which will
need an OP_PUSHDATA2 + 2-bytes for the 513 script bytes.

fixes#4224
-respendnotify=<cmd> Execute command when a network tx respends wallet
tx input (%s=respend TxID, %t=wallet TxID)
Add respendsobserved array to gettransaction, listtransactions, and
listsinceblock RPCs. This omits the malleated clones that are included
in the walletconflicts array.
Add RPC help for respendsobserved and walletconflicts (help was missing
for the latter).
Respend transactions that conflict with transactions already in the
wallet are added to it. They are not displayed unless they also involve
the wallet, or get into a block. If they do not involve the wallet,
they continue not to affect balance.
Transactions that involve the wallet, and have conflicting non-equivalent
transactions, are highlighted in red. When the conflict first occurs, a
modal dialog is thrown.
CWallet::SyncMetaData is changed to sync only to equivalent transactions.
When a conflict is added to the wallet, counter nConflictsReceived is
incremented. This acts like a change in active block height for the
purpose of triggering UI updates.
Allows network wallets and other clients to see transactions that respend
a prevout already spent in an unconfirmed transaction in this node's mempool.
Knowledge of an attempted double-spend is of interest to recipients of the
first spend. In some cases, it will allow these recipients to withhold
goods or services upon being alerted of a double-spend that deprives them
of payment.
As before, respends are not added to the mempool.
Anti-Denial-of-Service-Attack provisions:
- Use a bloom filter to relay only one respend per mempool prevout
- Rate-limit respend relays to a default of 100 thousand bytes/minute
- Define tx2.IsEquivalentTo(tx1): equality when scriptSigs are not considered
- Do not relay these equivalent transactions
Remove an unused variable declaration in txmempool.cpp.
ed5769f Move AcceptedConnection class to rpcserver.h. (Jeff Garzik)
854d013 RPC code movement: separate out JSON-RPC execution logic from HTTP server logic (Jeff Garzik)
c912e22 RPC cleanup: Improve HTTP server replies (Jeff Garzik)
1) support varying content types
2) support only sending the header
3) properly deliver error message as content, if HTTP error
4) move AcceptedConnection class to header, for wider use
By default, all command line parameters are converted into JSON string
values. There is no need to manually specify the incoming type.
A binary decision "parse as string or JSON?" is all that's necessary.
Convert to a simple class, initialized at runtime startup, which offers
a quick lookup to answer "parse as JSON?" conversion question.
Future parameter conversions need only to indicate the method name
and zero-based index of the parameter needing JSON parsing.
In the LookupIntern(), things changed are:
1. Call getaddrinfo_a() instead of getaddrinfo() if available, the former is a sync version of the latter;
2. Try using inet_pton()/inet_addr() to convert the input text to a network addr structure at first, if success the extra name resolving thread inside getaddrinfo_a() could be avoided;
3. An interruption point added in the waiting loop for return from getaddrinfo_a(), which completes the improve for thread responsiveness.
A easy way to see the effect is to kick off a 'bitcoind stop' immediately after 'bitcoind -daemon', before the change it would take several, or even tens of, minutes on a bad network situation to wait for the running bitcoind to exit, now it costs only seconds.
