Fix https://github.com/bitcoin/bitcoin/issues/6558. In particular, stop
parsing JSON after the first object or array is finished. Check that no
other garbage follows, and fail the parser if it does.
Since the introduction of the ScriptForMining callback, the mining
functions (setgenerate and generate) crash with an assertion failure
(due to a NULL pointer script returned) if the keypool is empty. Fix
this by giving a proper error.
Add error checking to CLevelDBWrapper for errors from
leveldb::DestroyDB(). Without it, if unlink() or DeleteFileW() fail to
delete files, they will fail silent. If they fail to delete any files,
CLevelDBWrapper will silently open and read the existing database.
Typically any permissions issues would be caught by leveldb as it churns
through many files as part of its compaction process, but it is
conceivable that this could cause problems on Windows with anti-virus
and indexing software.
Move mempool rejections to debug category `mempoolrej`, to make it possible
to show them without enabling the entire category `mempool` which is
high volume.
Add detailed state information to the errors, as it is no longer being
logged downstream.
Also add the state information to mempool rejection debug message in
ProcessMessages.
Remove unnecessary direct logging in CheckTransaction,
AcceptToMemoryPool, CheckTxInputs, CScriptCheck::operator()
All status information should be returned in the CValidationState.
Relevant debug information is also added to the CValidationState using
the recently introduced debug message.
Do keep the "BUG! PLEASE REPORT THIS! ConnectInputs failed against MANDATORY but not STANDARD flags"
error as it is meant to appear as bug in the log.
Add status codes specific to AcceptToMempool procession of transactions.
These can never happen due to block validation, and must never be sent
over the P2P network. Add assertions where appropriate.
- add static verifySize() function to PaymentServer and move the logging
on error into the function
- also use the new function in the unit test
- the function checks if the size is allowed as per BIP70
- remove an unneeded include of net.h in peertablemodel.cpp
- add const after size() in PeerTablePriv
- remove 2x unneeded else in functions
- replace a (int) typecast by (QVariant) to use Qt style
- remove unneeded include of peertablemodel.h from rpcconsole.cpp
Add a field `strDebugMessage` which can be passed to DoS or Invalid,
and queried using GetDebugMessage() to add extra troubleshooting
information to the validation state.
This gets rid of a warning. Add an assertion to make sure that the
reject code is in the correct range for the network protocol
(if it is outside the range it must be a bug)
