This problem is like earth (mostly harmless). After/during a
-reindex, it means the statistics about the last block file
reported in debug.log are always of blk00000.dat instead of the
last file. Apart from that, it means a few more database entries
need to be read when finding a file to append to the first time.
- even if we are allowed to fail pre-allocating, it's better to check
for sufficient space before calling AllocateFileRange() and if we
are out of disk space return with error()
- the above change allows us to remove the CheckDiskSpace() check
in CBlock::AcceptBlock()
- use it for displaying URI parsing warnings
- use it for displaying error and information in backup wallet function
(the information display is new and the error was a warning before)
- cleanup BitcoinGUI::incomingTransaction()
-- use message() + the information icon from message
-- comment out an unused parameter in the function definition and
declaration
-- move all pre-checks at the beginning of the function
In case a reorganisation fails, the internal state could become
inconsistent (memory only). Previously, a cache per block connect
or disconnect action was used, so blocks could not be applied in
a partial way. Extend this to a cache for the entire reorganisation,
making it atomic entirely. This also simplifies the code a bit.
- this allows to setup the trayicon before we have and want a trayicon menu
- should be of great use, when we remove that splash screen
- fixes a small bug with the toggleHideAction icon, which is not only used with
trayicon but also with the Mac dock
- 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
When a transaction A is in the memory pool, while a transaction B
(which shares an input with A) gets accepted into a block, A was
kept forever in the memory pool.
This commit adds a CTxMemPool::removeConflicts method, which
removes transactions that conflict with a given transaction, and
all their children.
This results in less transactions in the memory pool, and faster
construction of new blocks.
- can be triggerd by just adding -proxy=crashme with 0.7.1
- crash occured, when AppInit2() was left with return false; after the
first call to bitdb.open() (Step 6 in init)
- this is caused by GetDataDir() or .string() in CDBEnv::EnvShutdown()
called via the bitdb global destructor
- init fDbEnvInit and fMockDb to false in CDBEnv::CDBEnv()
These flags select features to be enabled/disabled during script
evaluation/checking, instead of several booleans passed along.
Currently these flags are defined:
* SCRIPT_VERIFY_P2SH: enable BIP16-style subscript evaluation
* SCRIPT_VERIFY_STRICTENC: enforce strict adherence to pubkey/sig encoding standards.
o Remove unused Leave and GetLock functions
o Make Enter and TryEnter private.
o Simplify Enter and TryEnter.
boost::unique_lock doesn't really know whether the
mutex it wraps is locked or not when the defer_lock
option is used.
The boost::recursive_mutex does not expose this
information, so unique_lock only infers this
knowledge. When taking the lock is defered, it
(randomly) assumes that the lock is not taken.
boost::unique_lock has the following definition:
unique_lock(Mutex& m_,defer_lock_t):
m(&m_),is_locked(false)
{}
bool owns_lock() const
{
return is_locked;
}
Thus it is a mistake to check owns_lock() in Enter
and TryEnter - they will always return false.
- remove an unwanted ";" at the end of the ~CCoinsView() destructor
- in FindBlockPos() and FindUndoPos() only call fclose(), is file is open
- fix an error string in the CBlockUndo class
feature in clang. These macros should primarily be used to
document which locks protect a given piece of data. Secondary it
can be used to document the set of held and excluded locks when
entering a function.
