Because this class replaces some usages of CBigNum, tests have been added to
verify that they function the same way. The only difference in their usage is
the handling of out-of-range numbers.
While operands are constrained to [-0x7FFFFFFF,0x7FFFFFFF], the results may
overflow. The overflowing result is technically unbounded, but in practice
it can be no bigger than the result of an operation on two operands. This
implementation limits them to the size of an int64.
CBigNum was unaware of this constraint, so it allowed for unbounded results,
which were then checked before use. CScriptNum asserts if an arithmetic
operation will overflow an int64_t, since scripts are not able to reach those
numbers anyway. Additionally, CScriptNum will throw an exception when
constructed from a vector containing more than 4 bytes This mimics the previous
CastToBigNum behavior.
- In wallet and GUI code LOCK cs_main as well as cs_wallet when
necessary
- In main.cpp SendMessages move the TRY_LOCK(cs_main) up, to encompass the call
to IsInitialBlockDownload.
- Make ActivateBestChain, AddToBlockIndex, IsInitialBlockDownload,
InitBlockIndex acquire the cs_main lock
Fixes#3997
All functions that use ChainActive but do not aquire the cs_main
lock themselves, need to be called with the cs_main lock held.
This commit adds assertions to all externally callable functions
that use chainActive or chainMostWork.
This will flag usages when built with -DDEBUG_LOCKORDER.
Drawback: The version string is no longer a valid git identifier.
For this reason the 'g' short hash prefix has been removed.
Exception: When building directly from a tag this behaves exactly like the previous behavior.
This allows formatting release versions with precision i.e. v0.9.2
This also allows arbitrary topicbranch names i.e. v0.9.1-glibc-compat
- prevents unsafe shutdowns on Windows, which is known to be
able to cause problems with wallet.dat
- if a users ends a Windows session, this will initiate a client shutdown
and show a Windows dialog, that tells the user what is going on (for
Windows Vista and higher it will even show a reason for blocking the
Windows session end)
glibc/libstdc++ have added new symbols in later releases. When running a new
binary against an older glibc, the run-time linker is unable to resolve the
new symbols and the binary refuses to run.
This can be fixed by adding our own versions of those functions, so that the
build-time linker does not emit undefined symbols for them.
This enables our binary releases to work on older Linux distros, while not
incurring the downsides of a fully static binary.
When we are over our outbound limit ThreadSocketHandler would try to
keep the connection if the peer was addnoded.
This didn't actually work for two reasons: It didn't actually run
the accept code due to mistaken code flow, and because we have a
limited number of outbound semaphores it couldn't actually use the
connection.
Instead it leaked the socket, which might have caused issue #4034.
This patch just takes out the non-functioning white-listing for now.
Use sensible categories (overall control, P2P, blockchain/UTXO and
mining, wallet, wallet-enabled mining) and sort within each.
Also remove unnecessary #ifdef ENABLE_WALLET from `rpcnet.cpp`.
Functionality-neutral change.
PrintBlockTree output was broken starting from e010af70.
Everything appears on one line.
PrintWallet() added the newline after a block, but this functionality
was removed and no newline was added.
Seemingly, no one noticed. Add a newline after the block information
to fix this.
