0655fac miner: indentation fixes, remove for (;;) (Philip Kaufmann)
|
|
|
|
- change a for (;;) into while (true), as we nowhere else use the first
- init nNonceFound to 0
- fix indentation in BitcoinMiner try/catch block
|
|
|
|
In addition, introduce a cached hash inside CTransaction, to prevent
recalculating it over and over again.
|
|
|
|
|
|
It's considered bad form to import things into the global namespace in a
header. Put it in the cpp files where it is needed instead.
|
|
- contains zero code changes

Fixes the following compiler warning
```
miner.cpp: In constructor ‘COrphan::COrphan(const CTransaction*)’:
miner.cpp:69:14: warning: ‘COrphan::feeRate’ will be initialized after [-Wreorder]
CFeeRate feeRate;
^
miner.cpp:68:12: warning: ‘double COrphan::dPriority’ [-Wreorder]
double dPriority;
^
miner.cpp:71:5: warning: when initialized here [-Wreorder]
COrphan(const CTransaction* ptxIn) : ptx(ptxIn), feeRate(0), dPriority(0)
```
|
|
Use CFeeRate instead of an int64_t for quantities that are
fee-per-size.
Helps prevent unit-conversion mismatches between the wallet,
relaying, and mining code.

783b182 Remove dummy PRIszX macros for formatting (Wladimir J. van der Laan)

787ee0c Check redeemScript size does not exceed 520 byte limit (Peter Todd)
4d79098 Increase IsStandard() scriptSig length (Peter Todd)
f80cffa Do not trigger a DoS ban if SCRIPT_VERIFY_NULLDUMMY fails (Peter Todd)
6380180 Add rejection of non-null CHECKMULTISIG dummy values (Peter Todd)
29c1749 Let tx (in)valid tests use any SCRIPT_VERIFY flag (Peter Todd)

Size specifiers are no longer needed now that we use typesafe tinyformat
for string formatting, instead of the system's sprintf.
No functional changes.
This continues the work in #3735.
|
|
|
|
|
|
This resolves a case in which a mismatch could be used to bloat up the
mempool by sending transactions that pay enough fee to relay, but not
to be mined, with the default policies.

Amend to d5f1e72. It turns out that BerkelyDB was including inttypes.h
indirectly, so we cannot fix this with just macros.
Trivial commit: apply the following script to all .cpp and .h files:
# Middle
sed -i 's/"PRIx64"/x/g' "$1"
sed -i 's/"PRIu64"/u/g' "$1"
sed -i 's/"PRId64"/d/g' "$1"
# Initial
sed -i 's/PRIx64"/"x/g' "$1"
sed -i 's/PRIu64"/"u/g' "$1"
sed -i 's/PRId64"/"d/g' "$1"
# Trailing
sed -i 's/"PRIx64/x"/g' "$1"
sed -i 's/"PRIu64/u"/g' "$1"
sed -i 's/"PRId64/d"/g' "$1"
After this commit, `git grep` for PRI.64 should turn up nothing except
the defines in util.h.

in 2014.
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.

Previously CreateNewBlock() didn't take into account the fact that
IsFinalTx() without any arguments tests if the transaction is considered
final in the *current* block, when both those functions really needed to
know if the transaction would be final in the *next* block.
Additionally the UI had a similar misunderstanding.
Also adds some basic tests to check that CreateNewBlock() is in fact
mining nLockTime-using transactions correctly.
Thanks to Wladimir J. van der Laan for rebase.

After the tinyformat switch sprintf() family functions support passing
actual std::string objects.
Remove unnecessary c_str calls (236 of them) in logging and formatting.
|
|
Moved includes of "db.h" into #ifdef ENABLE_WALLET blocks or remove
them.

ad898b4 Increase default -blockmaxsize/prioritysize to 750K/50K (Gavin Andresen)
|
|
|
|
The following mining-related RPC calls don't use the wallet:
- getnetworkhashps
- getmininginfo
- getblocktemplate
- submitblock
Enable them when compiling with --disable-wallet.
|
|
Also changes mempool to store CTxMemPoolEntries
to keep track of when they enter/exit the pool.
|
|
GetValueIn makes more sense as a CTransaction member.

I'm writing some wallet regression tests using -regtest mode, and
need to generate an initial multi-hundred-block chain. Repeatedly
calling setgenerate to generate one block is slow and doesn't
work properly, because block creation happens asynchronously.
This adds two features to setgenerate in -regtest mode:
1) Instead of being interpreted as number of threads to start, the
third argument is the number of blocks to generate.
2) setgenerate will not return until the block creation threads
have created the requested number of blocks.

- example: if util.h includes stdint.h, remove it from util.cpp, as
util.h is the first header included in util.cpp
|
|
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.

[Fee logic] Don't count txins for priority to encourage sweeping.
|
|
|
|
- moves 2 global variables from main.cpp/h to miner.cpp/h
- also removes 2 unneded includes in miner.cpp, that come from miner.h
already
|
|
|
|
This changes the priority calculation to not include the size of per-txin
data including up to 110 bytes of scriptsig so that transactions which
sweep up extra UTXO don't lose priority relative to ones that don't.
I'd toyed with some other variations, but it seems like any formulation
which results in an incentive stronger than making them not count will
sometimes create incentives to add extra outputs so that you have
extra inputs to consume later. The maximum credit is limited so that
users don't lose the disincentive to stuff random data in their
transactions, the limit of 110 is based on the size of a P2SH
redemption with a compressed public key.
This shouldn't need a staged deployment because the priority is not
used as a relay criteria, only a mining criteria.
