Prior to building, please confirm you have the correct source tree with the git log command. The first log entry should be the change setting the version:

commit 95a573b755219d7e1e078d53b8e11a8f0d7cade1
Author: Vinnie Falco <[email protected]>
Date:   Wed Jan 8 17:08:27 2014 -0800

   Set version to 0.20.1

Major Partner Issues Fixed

• rippled will crash randomly.
• Entries in the three parts of the order book are missing or do not match. In such a case, rippled will crash.
• Server loses sync randomly.
• This is due to rippled restarting after it crashes. That the server restarted is not obvious and appears to be something else.
• Server goes 'offline' randomly.
• This is due to rippled restarting after it crashes. That the server restarted is not obvious and appears to be something else.
• complete_ledgers part of server_info output says "None".
• This is due to rippled restarting and reconstructing the ledger after it crashes.
• If the node back end is corrupted or has been moved without being renamed in rippled.cfg, this can cause rippled to crash and restart.

Toolchain support

Starting with this release, the minimum supported version of GCC used to compile rippled is v4.8.

Significant Changes

• Don't log StatsD messages to the console by default.
• Fixed missing jtACCEPT job limit.

• Suspend processing requests if server is backed up.
• Multiple performance improvements and enhancements.
• Fixed locking.
• Refactored codebase to make it C++11 compliant.
• Multiple fixes to ledger acquisition, cleanup, and logging.
• Made multiple improvements to WebSockets server.
• Added Debian-style initscript (doc/rippled.init).
• Updated default config file (doc/rippled-example.cfg) to reflect best practices.
• Made changes to SHAMapTreeNode and visitLeavesInternal to conserve memory.
• Implemented new fee schedule:
• Transaction fee: 10 drops
• Base reserve: 20 XRP
• Incremental reserve: 5 XRP

• Fixed a store/fetch race condition in ther node back end.
• Fixed multiple comparison operations.
• Removed Sophia and Lightning databases.

Notice

If you are upgrading from version 0.12 or earlier of rippled, these next sections apply to you because the format of the rippled.cfg file changed around that time. If you have upgraded since that time and you have applied the configuration file fixes, you can safely ignore them.

New RocksDB back end

RocksDB is based on LevelDB with improvements from Facebook and the community. Preliminary tests show that it stalls less often than HyperLevelDB for our use cases.

If you are switching over from an existing back end, you have two options. You can remove your old database and let rippled recreate it as it re-syncs, or you can import your old database into the new one.

To remove your old database, make sure the server is shut down (rippled stop). Remove the db/ledger.db and db/transaction.db files. Remove all the files in your back end store directory (db/hashnode by default). Then change your configuration file to use the RocksDB back end and restart.

To import your old database, start by shutting the server down. Then modify the configuration file by renaming your [node_db] stanza to [import_db]. Create a new [node_db] stanza and specify a RocksDB back end with a different directory. Start the server with the command rippled --import. When the import finishes gracefully stop the server (rippled stop). Please wait for rippled to stop on its own because it can take several minutes for it to shut down after an import. Remove the old database, put the new database into place, remove the [import_db] section, change the [node_db] section to refer to the final location, and restart the server.

The recommended RocksDB configuration is:

[node_db]
type=RocksDB
path=db/hashnode
open_files=1200
filter_bits=12
cache_mb=256
file_size_mb=8
file_size_mult=2

Configuring your Node DB

You need to configure the NodeBackEnd that you want the server to use. See above for an example RocksDB configuration.

• Note: HyperLevelDB and RocksDB are not available on Windows platform.

    Set version to v0.12.0

Major Partner Issues Fixed

• Server Showing "Offline"

This issue was caused by LevelDB periodically compacting its internal data structure. While compacting, rippled's processing would stall causing the node to lose sync with the rest of the network. This issue was solved by switching from LevelDB to HyperLevelDB. rippled operators will need to change their ripple.cfg file. See below for configuration details.

• Premature Validation of Transactions

On rare occasions, a transaction would show as locally validated before the full network consensus was confirmed. This issue was resolved by changing the way transactions are saved.

• Missing Ledgers

Occasionally, some rippled servers would fail to fetch all ledgers. This left gaps in the local history and caused some API calls to report incomplete results. The ledger fetch code was rewritten to both prevent this and to repair any existing gaps.

Significant Changes

• The way transactions are saved has been changed. This fixes a number of ways transactions can incorrectly be reported as fully-validated.
• doTransactionEntry now works against open ledgers.
• doLedgerEntry now supports a binary option.
• A bug in getBookPage that caused it to skip offers is fixed.
• getNodeFat now returns deeper chains, reducing ledger acquire latency.
• Catching up if the (published ledger stream falls behind the network) is now more aggressive.
• I/O stalls are drastically reduced by using the HyperLevelDB node back end.
• Persistent ledger gaps should no longer occur.
• Clusters now exchange load information.

Release Candidates

RC1 was the first release candidate.

RC2 fixed a bug that could cause ledger acquires to stall.

RC3 fixed compilation under OSX.

RC4 includes performance improvements in countAccountTx and numerous small fixes to ledger acquisition.

RC5 changed the peer low water mark from 4 to 10 to acquire more server connections.

RC6 fixed some possible load issues with the network state timer and cluster reporting timers.

Issues

Fetching of historical ledgers is slower in this build than in previous builds. This is being investigated.
