2015-10-11Bump minrelaytxfee defaultWladimir J. van der Laan
To bridge the time until a dynamic method for determining this fee is merged. This is especially aimed at the stable releases (0.10, 0.11) because full mempool limiting, as will be in 0.12, is too invasive and risky to backport.

2015-06-15Add option `-alerts` to opt out of alert systemWladimir J. van der Laan
Make it possible to opt-out of the centralized alert system by providing an option `-noalerts` or `-alerts=0`. The default remains unchanged. This is a gentler form of #6260, in which I went a bit overboard by removing the alert system completely. I intend to add this to the GUI options in another pull after this.

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.

2015-03-11fix possible block db breakage during re-indexCory 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. Rebased-From: bb6acff07982dda68b5c2ac81c99dbd7255bb9cc Github-Pull: #5864
2015-03-09Ignore getaddr messages on Outbound connections.Ivan Pustogarov
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).

2015-02-24Sanitize command strings before logging them.Gregory Maxwell
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. Conflicts: src/main.cpp
2015-02-03Increase block download timeout base from 10 to 20 minutes.Gregory Maxwell
This harmonizes the block fetch timeout with the existing ping timeout and eliminates a guaranteed eventual failure from congestion collapse for a network operating right at its limit. It's unlikely that we wouldn't suffer other failures if we were really anywhere near the network's limit, and a complete avoidance of congestion collapse risk requires (I think) an exponential back-off. So this isn't a major concern, but I think it's also useful for reducing the complexity of understanding out timeouts. Github-Pull: #5647 Rebased-From: 3ff735c99ae75c21397079f49859b81e89a2f5f8

2014-12-22Check against MANDATORY flags prior to accepting to mempoolPeter Todd
Previously transactions were only tested again the STANDARD_SCRIPT_VERIFY_FLAGS prior to mempool acceptance, so any bugs in those flags that allowed actually-invalid transactions to pass would result in allowing invalid transactions into the mempool. Fortunately there is a second check in CreateNewBlock() that would prevent those transactions from being mined, resulting in an invalid block, however this could still be exploited as a DoS attack.

This still leaves transactions in mempool that are potentially invalid if the maturity period has been reorged out of, but at least they're not missing inputs entirely.

2014-11-24Improve chainstate/blockindex disk writing policyPieter Wuille
There are 3 pieces of data that are maintained on disk. The actual block and undo data, the block index (which can refer to positions on disk), and the chainstate (which refers to the best block hash). Earlier, there was no guarantee that blocks were written to disk before block index entries referring to them were written. This commit introduces dirty flags for block index data, and delays writing entries until the actual block data is flushed. With this stricter ordering in writes, it is now safe to not always flush after every block, so there is no need for the IsInitialBlockDownload() check there - instead we just write whenever enough time has passed or the cache size grows too large. Also updating the wallet's best known block is delayed until this is done, otherwise the wallet may end up referring to an unknown block. In addition, only do a write inside the block processing loop if necessary (because of cache size exceeded). Otherwise, move the writing to a point after processing is done, after relaying.
