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
rather than reusing ReadHTTPStatus() from the client mode.
The following additional HTTP request validations are added, both in line with
existing HTTP client practice:
1) HTTP method must be GET or POST. Most clients use POST, some
use GET. Either way, this continues to work.
2) HTTP URI must start with "/" character.
Normal URI is "/" (a 1-char string), so this is fine.
ReadHTTPStatus() is currently overloaded: In client mode, it properly parses
and receives an HTTP status line. In server mode, it incorrectly parses the
HTTP request line as an HTTP status line.
This server mode bug has never mattered, because the RPC server never
cared about the URI (path) provided in the HTTP request. That will change in
the future, so go ahead and begin fixing the problem.
This patch is cosmetic, and should result in NO behavior changes.
Further renames:
ReadHTTPHeader -> ReadHTTPHeaders
ReadHTTP -> ReadHTTPMessage
The original test (checking whether the transaction occurs in the
txindex) is not usable anymore, as it will miss anything already
fully spent. However, as merkle transactions (and by extension,
wallet transactions) track which block they were last seen being
included in, we can use that to determine the need for
rebroadcasting.
- add setStatusTip() in addition to setTooltip() where it makes sense
- add only setStatusTip() if GUI element is only used in main- or tray menu
- add an event filter on our BitcoinGUI object to prevent garbelled text
on the status bar, which happens when we use it for e.g. displaying
block-sync state and then a QEvent::StatusTip wants to write own text to it
- remove a double translation of "Bitcoin client"
This is to support the signrawtransaction API call; given the public
keys involved in a multisig transaction, this gives back the redeemScript
needed to sign it.
signrawtransaction was unable to sign pay-to-script-hash inputs
when given the list of private keys to use. With this commit
you can provide the p2sh redemption script in the list of
inputs.
As the coinset data refers to the best block, stored in the block
tree. Flushing the coin set first can cause inconsistencies if
the process gets killed in between.
- "ThreadIRCSeed started" was not displayed, even if the thread ran
(although only for a short time as the "do we want this thread?"-checks
happen IN ThreadIRCSeed2())
- the patch ensures we always get that message
- add a "ThreadIRCSeed trying to connect..." message
- add missing "ThreadDumpAddress started" message
- instead of "return false;" use "return QDialog::eventFilter(object,
event);" to harmonize this event filter with our default behaviour
- remove orphan spaces found while editting the files
Implements #1948
- Add macro `CLIENT_VERSION_IS_RELEASE` to clientversion.h
- When running a prerelease (the above macro is `false`):
- In UI, show an orange warning bar at the top. This will be used for other
warnings (and alerts) as well, instead of the status bar.
- For `bitcoind`, show the warning in the "errors" field in `getinfo`
response.
CreateNewBlock was reading pindexBest at the start before taking the lock
so it was possible to have the the block content not match the prevheader
and this can also trigger a newly added assert in ConnectBlock.
I noticed this during a code review after twobitcoins reported that ab91bf39
(BIP30 for all blocks) could cause a null dereference on a modified node
that mined during the IBD, or on testnet when it reached heights 91842 and
91880 due to CreateNewBlock calling ConnectBlock with pindex->phashBlock NULL.
- remove uiInterface.InitMessage() calls from ThreadImport(), as Qt
doesn't like them getting called out of it's main thread and because the
thread will continue to run after the GUI was loaded
Split off CBlockTreeDB and CCoinsViewDB into txdb-*.{cpp,h} files,
implemented by either LevelDB or BDB.
Based on code from earlier commits by Mike Hearn in his leveldb
branch.
Given that the block tree database (chain.dat) and the active chain
database (coins.dat) are entirely separate now, it becomes legal to
swap one with another instance without affecting the other.
This commit introduces a check in the startup code that detects the
presence of a better chain in chain.dat that has not been activated
yet, and does so efficiently (in batch, while reusing the blk???.dat
files).
