2013-04-03Shutdown cleanup prep-workGavin Andresen
Create a boost::thread_group object at the qt/bitcoind main-loop level that will hold pointers to all the main-loop threads. This will replace the vnThreadsRunning[] array. For testing, ported the BitcoinMiner threads to use its own boost::thread_group.

2013-02-18Internal RNG for approximateBestSubset to prevent degenerate behavior.Gregory Maxwell
This fixes test_bitcoin failures on openbsd reported by dhill on IRC. On some systems rand() is a simple LCG over 2^31 and so it produces an even-odd sequence. ApproximateBestSubset was only using the least significant bit and so every run of the iterative solver would be the same for some inputs, resulting in some pretty dumb decisions. Using something other than the least significant bit would paper over the issue but who knows what other way a system's rand() might get us here. Instead we use an internal RNG with a period of something like 2^60 which is well behaved. This also makes it possible to make the selection deterministic for the tests, if we wanted to implement that.

Provides a method to get the difference between network adjusted time and local time from the RPC interface.
2013-01-01OutputDebugStringF code cleanupGavin Andresen
Initialize the OutputDebugStringF mutex and file pointer using boost::call_once, to be thread-safe. Make the return value of OutputDebugStringF really be the number of characters written (*printf() semantics). Declare the fReopenDebugLog flag volatile, since it is changed from a signal handler. And don't declare OutputDebugStringF() as inline.

Space separation between major fields is easier for human eyes and libs to parse.

2012-12-06Allow lengthy block reconnections to be interruptedPieter Wuille
When the coin database is out of date with the block database, the best block in it is automatically switched to. This reconnection process can take time, so allow it to be interrupted. This also stops block connection as soon as shutdown is requested, leading to a faster shutdown.
2012-11-29Add GetTempPath() to utilPieter Wuille
2012-11-26update CClientUIInterface and remove orphan Wx stuffPhilip Kaufmann
- fix ThreadSafeMessageBox always displays error icon - allow to specify MSG_ERROR / MSG_WARNING or MSG_INFORMATION without a custom caption / title - allow to specify CClientUIInterface::ICON_ERROR / ICON_WARNING and ICON_INFORMATION (which is default) as message box icon - remove CClientUIInterface::OK from ThreadSafeMessageBox-calls, as the OK button will be set as default, if none is specified - prepend "Bitcoin - " to used captions - rename BitcoinGUI::error() -> BitcoinGUI::message() and add function documentation - change all style parameters and enum flags to unsigned - update code to use that new API - update Client- and WalletModel to use new BitcoinGUI::message() and rename the classes error() method into message() - include the possibility to supply the wanted icon for messages from Client- and WalletModel via "style" parameter
2012-11-09don't use memset() in privacy/security relevant code partsPhilip Kaufmann
As memset() can be optimized out by a compiler it should not be used in privacy/security relevant code parts. OpenSSL provides the safe OPENSSL_cleanse() function in crypto.h, which perfectly does the job of clean and overwrite data. For details see: http://www.viva64.com/en/b/0178/ - change memset() to OPENSSL_cleanse() where appropriate - change a hard-coded number from netbase.cpp into a sizeof()
2012-10-20Pre-allocate block and undo files in chunksPieter Wuille
Introduce a AllocateFileRange() function in util, which wipes or at least allocates a given range of a file. It can be overriden by more efficient OS-dependent versions if necessary. Block and undo files are now allocated in chunks of 16 and 1 MiB, respectively.

I'm not sure why this wasn't done before. - Removes typedef of pthread_t on Windows, which fixes a native compile issue on mingw.
2012-08-23Handle locked pages more robustly (Fixes issue #1462)Wladimir J. van der Laan
Memory locks do not stack, that is, pages which have been locked several times by calls to mlock() will be unlocked by a single call to munlock(). This can result in keying material ending up in swap when those functions are used naively. In this commit a class "LockedPageManager" is added that simulates stacking memory locks by keeping a counter per page.

2012-08-20Suppress output when running unit tests.Gavin Andresen
This does two things: 1) Now does not output to debug.log if -printtodebugger flag is passed 2) Unit tests set -printtodebugger so only test results are output to stdout Note that -printtodebugger only actually prints to the debugger on Windows.

2012-06-22Introduce -debugnet option, thereby quieting some redundant debug messagesJeff Garzik
