Use non-blocking connects, and a select() call to wait a predefined
time (5s by default, but configurable with -timeout) for either
success or failure. This allows much more connections to be tried
per time unit.
Based on a patch by phantomcircuit.
For instance any nBits compressed value from 0x1a44b800 thru
0x1a44b9ff will show as difficulty 244139.4816. This patch will
more accurately convert the nBits compressed values to the double
difficulty.
This will display any of the recent difficulty levels slightly
differently though. Early difficulties and testnet difficulties are
not large enough to trigger this bug.
None of the actual targets or compressed targets are changed, only
the conversion to the floating point difficulty is changed and afaik
it is only ever displayed, never converted back so the patch does not
effect the target calculations, binary files, databases nor the binary
protocol.
Transactions created with the new minimal fee policy would not be
relayed by the network. Therefore, we separate the minimal fee that
is necessary to relay and to create, leaving the creation one at
the old amount, for now.
With the separation of CENT and MIN_TX_FEE, it is now reasonable
to create change outputs between 0.01 and 0.0005, as these are
spendable according to the policy, even though they require a fee
to be paid.
Also, when enough fee was already present, everything can go into
a change output, without further increasing the fee.
When rescanning, if the scanned transaction is already in the wallet, it
is skipped. However, if someone sends a transaction, does not wait for
confirmation, switches wallets, waits for a block that contains his original
transaction, and switches wallets again, a rescan will leave his wallet
transaction (which has no merkle branch, so no confirmations) untouched.
This reverts commit 69ae372b51 which
removes support for building the Mac version of Bitcoin with UPnP
support and UPnP disabled by default (which should be the default,
according to the community vote and as its the default on all
other platforms).
* A new option -dns is introduced that enables name lookups in
-connect and -addnode, which is not enabled by default,
as it may be considered a security issue.
* A Lookup function is added that supports retrieving one or
more addresses based on a host name
* CAddress constructors (optionally) support name lookups.
* The different places in the source code that did name lookups
are refactored to use NameLookup or CAddress instead (dns seeding,
irc server lookup, getexternalip, ...).
* Removed ToStringLog() from CAddress, and switched to ToString(),
since it was empty.
Use case: Customer owes you bitcoins, so you create a payment address
associated with an account with a negative balance (the amount they owe).
When customer pays, that account balance will go to zero.
