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
- remove pathEnv from CDBEnv, as this attribute is not needed
- change path parameter in ::Open() to a reference
- make nDbCache variable an unsigned integer
- remove a missplaced ";" behin ::IsMock()
- this allows the client to listen on via -bind specified addresses
(e.g. 127.0.0.1), even when a network (IPv4 in that case) was blocked
via e.g -onlynet="Tor"
- introduce enum BindFlags to avoid passing multiple bools to Bind()
- make -bind help text clear we ALWAYS listen on the specified address
- remove an unused variable
- remove 2 unneeded IsLimited() checks before calling Bind(), which does
these checks anyway
- usage case: specify -bind=127.0.0.1 -onlynet="Tor" to allow incoming
connections to a Tor hidden service, but still don't allow other IPv4
nodes to connect / get connected
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()
Flushes the blktree/ and coins/ databases, and reindexes the
block chain files, as if their contents was loaded via -loadblock.
Based on earlier work by Jeff Garzik.
- ensure header inclusion guard is named after the header file
- add missing comments at the end of some inclusion guards
- add a small Qt5 compatibility fix in macdockiconhandler.h
