2015-09-24Creates unittests for addrman, makes addrman testable.EthanHeilman
Adds several unittests for addrman to verify it works as expected. Makes small modifications to addrman to allow deterministic and targeted tests.

2015-04-19nLastTry is only used for addrman entriesPieter Wuille
No need to define it for every CAddress, as it's memory only anyway.
2015-03-23Scale up addrmanPieter Wuille

2015-03-23Make addrman's bucket placement deterministic.Pieter Wuille
Give each address a single fixed location in the new and tried tables, which become simple fixed-size arrays instead of sets and vectors. This prevents attackers from having an advantages by inserting an address multiple times. This change was suggested as Countermeasure 1 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015. It is also more efficient.

2014-08-31rework overhauled serialization methods to non-staticKamil Domanski
Thanks to Pieter Wuille for most of the work on this commit. I did not fixup the overhaul commit, because a rebase conflicted with "remove fields of ser_streamplaceholder". I prefer not to risk making a mistake while resolving it.
2014-08-31overhaul serialization codeKamil Domanski
The implementation of each class' serialization/deserialization is no longer passed within a macro. The implementation now lies within a template of form: template <typename T, typename Stream, typename Operation> inline static size_t SerializationOp(T thisPtr, Stream& s, Operation ser_action, int nType, int nVersion) { size_t nSerSize = 0; /* CODE */ return nSerSize; } In cases when codepath should depend on whether or not we are just deserializing (old fGetSize, fWrite, fRead flags) an additional clause can be used: bool fRead = boost::is_same<Operation, CSerActionUnserialize>(); The IMPLEMENT_SERIALIZE macro will now be a freestanding clause added within class' body (similiar to Qt's Q_OBJECT) to implement GetSerializeSize, Serialize and Unserialize. These are now wrappers around the "SerializationOp" template.
2014-08-28add missing header end commentsPhilip Kaufmann
- ensures a consistent usage in header files - also add a blank line after the copyright header where missing - also remove orphan new-lines at the end of some files

2014-07-09move rand functions from util to new random.h/.cppPhilip Kaufmann
2014-07-09add GetRandBytes() as wrapper for RAND_bytes()Philip Kaufmann
- add a small wrapper in util around RAND_bytes() and replace with GetRandBytes() in the code to log errors from calling RAND_bytes() - remove OpenSSL header rand.h where no longer needed
2014-06-25Move network-time related functions to timedata.cpp/hWladimir J. van der Laan
The network time-offset-mangement functions from util.cpp are moved to timedata.(cpp|h). This breaks the dependency of util on netbase.

2013-11-10Cleanup code using forward declarations.Brandon Dahler
Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.
2013-10-30re-work -debug switch handlingPhilip Kaufmann
- re-work -debug help message text - make -debug log every debugging information again (even all categories) - remove unneeded fDebug checks in front of LogPrint()/qDebug(), as that check is done in LogPrintf() when category is != NULL (true for all LogPrint() calls - remove fDebug ONLY in code which is NOT performance-critical - harmonize addrman category name - deprecate -debugnet usage, should be used via -debug=net and remove the corresponding global

2012-02-24CAddrMan: stochastic address managerPieter Wuille
Design goals: * Only keep a limited number of addresses around, so that addr.dat does not grow without bound. * Keep the address tables in-memory, and occasionally write the table to addr.dat. * Make sure no (localized) attacker can fill the entire table with his nodes/addresses. See comments in addrman.h for more detailed information.
