48265f3cf4 Revert mining changes in #5957
This reverts commit e2edf95cd3 6b04508e37 0df67f1f7a,
except the changes to the RPC tests.

A `generate` RPC call is introduced based on the old code.

Trigger -alertnotify if network is upgrading without you
This adds a -regetest-only undocumented (for regression testing only)
command-line option -blockversion=N to set block.nVersion.

Adds to the "has the rest of the network upgraded to a
block.nVersion we don't understand" code so it calls
-alertnotify when 51 of the last 100 blocks are up-version.
But it only alerts once, not with every subsequent new, upversion
block.

And adds a forknotify.py regression test to make sure it works.

Tested using forknotify.py:

Before adding CAlert::Notify, get:
Assertion failed: -alertnotify did not warn of up-version blocks

Before adding code to only alert once:
Assertion failed: -alertnotify excessive warning of up-version blocks

After final code in this pull:
Tests successful

629d75faac Combine CCoinsViewCache's HaveCoins and const GetCoins into AccessCoins.
The efficient version of CCoinsViewCache::GetCoins only works for known-to-exist
cache entries, requiring a separate HaveCoins call beforehand. This is
inefficient as both perform a hashtable lookup.

Replace the non-mutable GetCoins with AccessCoins, which returns a potentially-NULL
pointer. This also decreases the overloading of GetCoins.

Also replace some copying (inefficient) GetCoins calls with equivalent AccessCoins,
decreasing the copying.

ad49c256c3 Split up util.cpp/h
Split up util.cpp/h into:

- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)

The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).

Breaks dependency of sha256.cpp on all the things pulled in by util.

6c37f7fd78 getrawchangeaddress should fail when keypool exhausted
An user on IRC reported an issue where `getrawchangeaddress`
keeps returning a single address when the keypool is exhausted.
In my opinion this is strange behaviour.

- Change CReserveKey to fail when running out of keys in the keypool.
- Make `getrawchangeaddress` return RPC_WALLET_KEYPOOL_RAN_OUT when
  unable to create an address.
- Add a Python RPC test for checking the keypool behaviour in combination
  with encrypted wallets.

f48742c2bf Get rid of C99 PRI?64 usage in source files
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.

Fix off-by-one errors in use of IsFinalTx()
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.

c8b74258ba setgenerate creates multiple blocks in -regtest mode
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.

379778bde6 core: remove includes in .cpp, if header is already in .h
- example: if util.h includes stdint.h, remove it from util.cpp, as
  util.h is the first header included in util.cpp

51ed9ec971 Cleanup code using forward declarations.
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.

d6eb259953 [Fee logic] Don't count txins for priority to encourage sweeping.
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.

f1dbed9233 miner: constify CreateNewBlock() arg scriptPubKeyIn 2013-08-25 20:16:23 -04:00

7e17018995 CreateNewBlock() now takes scriptPubKey argument,
rather than a key.

CreateNewBlockWithKey() helper is added to restore existing functionality,
making this an equivalent-transformation change.
