f7303f9 Use equivalent PoW for non-main-chain requests (Pieter Wuille)

00dcaf4 Change download logic to allow calling getheaders/getdata on inbound peers (Suhas Daftuar)
|
|
This adds a -prune=N option to bitcoind, which if set to N>0 will enable block
file pruning. When pruning is enabled, block and undo files will be deleted to
try to keep total space used by those files to below the prune target (N, in
MB) specified by the user, subject to some constraints:
- The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP),
- N must be at least 550MB (chosen as a value for the target that could
reasonably be met, with some assumptions about block sizes, orphan rates,
etc; see comment in main.h),
- No blocks are pruned until chainActive is at least 100,000 blocks long (on
mainnet; defined separately for mainnet, testnet, and regtest in chainparams
as nPruneAfterHeight).
This unsets NODE_NETWORK if pruning is enabled.
Also included is an RPC test for pruning (pruning.py).
Thanks to @rdponticelli for earlier work on this feature; this is based in
part off that work.

0421c18 Fix CheckBlockIndex for reindex. (mrbandrews)

4e38217 Chainparams: Refactor: Remove redundant HashGenesisBlock() getter (Jorge Timón)
|
|
Some tests in CheckBlockIndex require chainActive.Tip(), but when reindexing, chainActive has not been set on the first call to CheckBlockIndex.
reindex.py starts a node, mines 3 blocks, stops, and reindexes with CheckBlockIndex enabled.

|
Also adds a test to CheckBlockIndex

f14e687 Chainparams: Decouple CAlert from CChainParams (Jorge Timón)
|
|
|
|
SendMessages will now call getheaders on both inbound and outbound peers,
once the headers chain is close to synced. It will also try downloading
blocks from inbound peers once we're out of initial block download (so
inbound peers will participate in parallel block fetching for the last day
or two of blocks being downloaded).

This adds more tests to CheckBlockIndex:
- HAVE_DATA is true iff nTx > 0
- BLOCK_VALID_TRANSACTIONS is true iff nTx > 0
- BLOCK_VALID_TRANSACTIONS is true for a block and all parents iff
nChainTx > 0

0f5954c Regression test for ResendWalletTransactions (Gavin Andresen)
|
|
This adds a -checkblockindex (defaulting to true for regtest), which occasionally
does a full consistency check for mapBlockIndex, setBlockIndexCandidates, chainActive, and
mapBlocksUnlinked.

Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions."
I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived).
I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by:
1. Running bitcoind -connect=0.0.0.0:8333
2. Creating a couple of send-to-self transactions
3. Connect to a peer using -addnode
4. Waited a while, monitoring debug.log, until I see:
```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions```
One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.

bb6acff fix possible block db breakage during re-index (Cory Fields)
|
|
When re-indexing, there are a few cases where garbage data may be skipped in
the block files. In these cases, the indices are correctly written to the index
db, however the pointer to the next position for writing in the current block
file is calculated by adding the sizes of the valid blocks found.
As a result, when the re-index is finished, the index db is correct for all
existing blocks, but the next block will be written to an incorrect offset,
likely overwriting existing blocks.
Rather than using the sum of all valid blocks to determine the next write
position, use the end of the last block written to the file. Don't assume that
the current block is the last one in the file, since they may be read
out-of-order.

Not used, and REGTEST already allows creating blocks at
the lowerst possible difficulty.

eec3713 make CMessageHeader a dumb storage class (Cory Fields)

This changes the TestingSetup fixture to be per-unit-test rather than global.
Most tests don't need it, so it's only invoked in a few.

It shouldn't know or care about bitcoind's chain param selection
|
|
With headers-first we can compare against the best header timestamp, rather
than using checkpoints which require code updates to maintain.

eb1c2cd Split logic to undo txin's off DisconnectBlock. (Daniel Kraft)
|
|
Normally bitcoin core does not display any network originated strings without
sanitizing or hex encoding. This wasn't done for strcommand in many places.
This could be used to play havoc with a terminal displaying the logs,
especially with printtoconsole in use.
Thanks to Evil-Knievel for reporting this issue.
|
|
The only time when a client sends a "getaddr" message is when he
esatblishes an Outbound connection (see ProcessMessage() in
src/main.cpp). Another bitcoin client is expected to receive a
"getaddr" message only on Inbound connection. Ignoring "gettaddr"
requests on Outbound connections can resolve potential privacy issues
(and as was said such request normally do not happen anyway).

A lot of times, disk corruption problems appear here.
To facilitate debugging and troubleshooting, add position information
to the error messages.
|
|
Instead, create a separate function that applies the undo operation of a
CTxInUndo object onto a CCoinsViewCache. This method is used from
DisconnectBlock.
