2012-10-09	Send --help message to stdout i.s.o stderr	Wladimir J. van der Laan
	This allows fun stuff such as `bitcoin --help \| less`, and more easy piping to files. Looking at other tools such as bash, gcc, they all send their help text to stdout.
2012-10-09	Add a backup warning to the encryptwallet RPC command	kjj2

2012-09-17	Apply BIP30 checks to all blocks except the two historic violations.	Gregory Maxwell
	Matt pointed out some time ago that there existed a minor DOS attack where a node in its initial block download could be wedged by an overwrite attack in a fork created between checkpoints before a time where BIP30 was enforced. Now that the BIP30 timestamp is irreversibly past the check can be more aggressive and apply to all blocks except the two historic violations.
2012-09-10	select(): Use precise fd presence check, rather than imprecise hSocketMax test	Jeff Garzik

2012-09-10	Bugfix: Don't consider invalid listening socket in hSocketMax	Luke Dashjr
	Fixed upstream in 8f10a2889089af1b2ac64802360494b54c8c7ff1.
2012-09-06	Correct LoadWallet() return value (false -> DB_LOAD_OK)	xanatos
	Equivalent code. (false == 0 == DB_LOAD_OK). Fixes #1706.
2012-08-27	Bump version to 0.4.8	Luke Dashjr

2012-08-27	Special-case the last alert for alert-key-compromised case	Gavin Andresen
	Hard-code a special nId=max int alert, to be broadcast if the alert key is ever compromised. It applies to all versions, never expires, cancels all previous alerts, and has a fixed message: URGENT: Alert key compromised, upgrade required Variations are not allowed (ignored), so an attacker with the private key cannot broadcast empty-message nId=max alerts.
2012-08-26	Support sending to script (P2SH) addresses	Luke Dashjr
	Upstream partials from 9e470585b35a84fcb7f6aa41ac0216c117e2a5e1, e679ec969c8b22c676ebb10bea1038f6c8f13b33, and 922e8e2929a2e78270868385aa46f96002fbcff3.
2012-08-26	Checkpoint at block 185333 (and remove a couple of intermediate checkpoints)	Gavin Andresen

2012-08-26	Reject block.nVersion<=1 blocks if network has upgraded to version=2	Gavin Andresen
	If 950 of the last 1,000 blocks are nVersion=2, reject nVersion=1 (or zero, but no bitcoin release has created block.nVersion=0) blocks -- 75 of last 100 on testnet3. This rule is being put in place now so that we don't have to go through another "express support" process to get what we really want, which is for every single new block to include the block height in the coinbase.
2012-08-26	Block height in coinbase as a new block rule	Gavin Andresen
	"Version 2" blocks are blocks that have nVersion=2 and have the block height as the first item in their coinbase. Block-height-in-the-coinbase is strictly enforced when version=2 blocks are a supermajority in the block chain (750 of the last 1,000 blocks on main net, 51 of 100 for testnet). This does not affect old clients/miners at all, which will continue producing nVersion=1 blocks, and which will continue to be valid.
2012-08-26	Add CBlock::CURRENT_VERSION and CTransaction::CURRENT_VERSION constants.	Gavin Andresen
	Partial of upstream dae3e10a5abe93833c57183b7c00f1db9200f46e

2012-07-22	CBigNum: Convert negative int64 values in a more well-defined way	Luke Dashjr
	Since the minimum signed integer cannot be represented as positive so long as its type is signed, and it's not well-defined what happens if you make it unsigned before negating it, we instead increment the negative integer by 1, convert it, then increment the (now positive) unsigned integer by 1 to compensate
2012-07-22	Fix signed subtraction overflow in CBigNum::setint64().	Ricardo M. Correia
	As noticed by sipa (Pieter Wuille), this can happen when CBigNum::setint64() is called with an integer value of INT64_MIN (-2^63). When compiled with -ftrapv, the program would crash. Otherwise, it would execute an undefined operation (although in practice, usually the correct one).
2012-07-06	Do not consider inbound peers for outbound network group exclusion.	Gregory Maxwell
	Bitcoin will not make an outbound connection to a network group (/16 for IPv4) that it is already connected to. This means that if an attacker wants good odds of capturing all a nodes outbound connections he must have hosts on a a large number of distinct groups. Previously both inbound and outbound connections were used to feed this exclusion. The use of inbound connections, which can be controlled by the attacker, actually has the potential of making sibyl attacks _easier_: An attacker can start up hosts in groups which house many honest nodes and make outbound connections to the victim to exclude big swaths of honest nodes. Because the attacker chooses to make the outbound connection he can always beat out honest nodes for the consumption of inbound slots. At _best_ the old behavior increases attacker costs by a single group (e.g. one distinct group to use to fill up all your inbound slots), but at worst it allows the attacker to select whole networks you won't connect to. This commit makes the nodes use only outbound links to exclude network groups for outbound connections. Fancier things could be done, like weaker exclusion for inbound groups... but simplicity is good and I don't believe more complexity is currently needed.

2012-06-20	print large orphan warning BEFORE deleting pvMsg	Gavin Andresen

2012-06-20	Bump VERSION so we can differentiate between 0.4.7rc2 and 0.4.7rc3	Luke Dashjr

2012-06-20	Remove invalid dependent orphans from memory	Gavin Andresen
	Remove orphan transactions from memory once all of their parent transactions are received and they're still not valid. Thanks to Sergio Demian Lerner for suggesting this fix.
2012-06-20	Further DoS prevention: Verify signatures last	Gavin Andresen
	Loop over all inputs doing inexpensive validity checks first, and then loop over them a second time doing expensive signature checks. This helps prevent possible CPU exhaustion attacks where an attacker tries to make a victim waste time checking signatures for invalid transactions.
2012-06-20	Optimize orphan transaction handling	Gavin Andresen
	Changes suggested by Sergio Demian Lerner to help prevent potential DoS attacks.
2012-06-18	Don't overflow integer on 32-bit machines.	Ricardo M. Correia
	This was causing test_bitcoin to abort on a 32-bit system likely due to -ftrapv.
2012-06-18	Don't overflow signed ints in CBigNum::setint64().	Ricardo M. Correia
	CBigNum::setint64() does 'n <<= 8', where n is of type "long long". This leads to shifting onto and past the sign bit, which is undefined behavior in C++11 and can cause problems in the future.
2012-06-18	Document how to build/run unit tests	Gavin Andresen

2012-06-14	Include limits, not climints (using std::numeric_limits now)	Gavin Andresen

2012-06-14	Use std::numeric_limits<> for typesafe INT_MAX/etc	Gavin Andresen

2012-06-12	Bugfix: Move IsStandard scriptSig size check out of IsPushOnly, since BIP16 ↵	Luke Dashjr
	verification uses the latter too This caused clients to reject block #177618 since it has a P2SH transaction with over 200 bytes in scriptSig. (Upstream commit: e679ec969c8b22c676ebb10bea1038f6c8f13b33)
2012-06-06	fix an incorrect if-clause in net.cpp	Philip Kaufmann

2012-06-06	Serialize access to debug.log stream	Michael Hendricks
	Acquire an exclusive, advisory lock before sending output to debug.log and release it when we're done. This should avoid output from multiple threads being interspersed in the log file. We can't use CRITICAL_SECTION machinery for this because the debug log is written during startup and shutdown when that machinery is not available. (Thanks to Gavin for pointing out the CRITICAL_SECTION problems based on his earlier work in this area)
2012-05-26	.gitignore: add test_bitcoin	Jeff Garzik

2012-05-22	Prevent crashes due to missing or corrupted blk????.dat records	Jeff Garzik

2012-05-22	Prevent crashes due to missing or corrupted database records	Jeff Garzik
	Any problems seen during deserialization will throw an uncaught exception, crashing the entire bitcoin process. Properly return an error instead, so that we may at least log the error and gracefully shutdown other portions of the app.
2012-05-22	Correct debug.log output to show correct function the debug is coming from.	R E Broadley

2012-05-20	Update License in File Headers	Fordy
	I originally created a pull to replace the "COPYING" in crypter.cpp and crypter.h, but it turned out that COPYING was actually the correct file.
2012-05-20	remove 2 ugly spaces from a message string	Philip Kaufmann

2012-05-18	Always check return values of TxnBegin() and TxnCommit()	Jeff Garzik
	PARTIAL, since d68dcf7 isn't backported (yet)
2012-05-17	Hopefully final fix for the stuck blockchain issue	Pieter Wuille
	Immediately issue a "getblocks", instead of a "getdata" (which will trigger the relevant "inv" to be sent anyway), and only do so when the previous set of invs led us into a known and attached part of the block tree.
