fix signed/unsigned in strprintf and CNetAddr::GetByte()
|
|
|
|
- I checked every occurance of strprintf() in the code and used %u, where
unsigned vars are used
- the change to GetByte() was made, as ip is an unsigned char

It should be pprev, because the next one is pnext, and it's printing the memory address of the CBlockIndex (so pSomething).

This fixes two alert system vulnerabilities found by
Sergio Lerner; you could send peers unlimited numbers
of invalid alert message to try to either fill up their
debug.log with messages and/or keep their CPU busy
checking signatures.
Fixed by disconnecting/banning peers if they send 10 or more
bad (invalid/expired/cancelled) alerts.

"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.

Add 'mempool' P2P command, and extend 'getdata' behavior
|
|
Optimize JSON-RPC getblockhash
|
|
- If the height is in the first half, start at the genesis block and go up, rather than at the top
- Cache the last lookup and use it as a reference point if it's close to the next request, to make linear lookups always fast

to permit downloading of mempool transactions from the remote peer.

Adds CBlock::CURRENT_VERSION and CTransaction::CURRENT_VERSION
constants, and makes non-CURRENT_VERSION transactions nonstandard.
This will help make future upgrades smoother.

::addUnchecked()'s only caller already takes the necessary lock,
and has already calculated the TX's hash.

This throws an exception from CreateNewBlock otherwise, which is not safe without #1245!

In LoadExternalBlockFile(), errors are already caught... silently.
Add a warning message, even though we do not abort the program due to
load error.

Gets rid of `MainFrameRepaint` in favor of specific update functions that tell the UI exactly what changed.
This improves the efficiency of various handlers. Also fixes problems with mined transactions not showing up until restart.
The following notifications were added:
- `NotifyBlocksChanged`: Block chain changed
- `NotifyKeyStoreStatusChanged`: Wallet status (encrypted, locked) changed.
- `NotifyAddressBookChanged`: Address book entry changed.
- `NotifyTransactionChanged`: Wallet transaction added, removed or updated.
- `NotifyNumConnectionsChanged`: Number of connections changed.
- `NotifyAlertChanged`: New, updated or cancelled alert. As this finally makes it possible for the UI to know when a new alert arrived, it can be shown as OS notification.
These notifications could also be useful for RPC clients. However, currently, they are ignored in bitcoind (in noui.cpp).
Also brings back polling with timer for numBlocks in ClientModel. This value updates so frequently during initial download that the number of signals clogs the UI thread and causes heavy CPU usage. And after initial block download, the value changes so rarely that a delay of half a second until the UI updates is unnoticable.

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.

Rather than storing ftell(3)'s return value -- a long -- in an
unsigned int, we store and check a properly typed temp. Then, assured a
non-negative value, we store in nBlockPosRet.

At these code sites, it is preferable to cast rather than change
a variable's type.

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.

In addition to standard code separation, this change opens the door
to fixing several include inter-dependencies.

foo.size() typically returns an unsigned integral type; make loop variables
match those types' signedness.
