Patch 1 #2665

Dock icon on macosx already has show/hide functionality. This results in erratic behavior.

Any problems seen during deserialization will throw an uncaught
exception, crashing the entire bitcoin process.  Properly return an
error instead, so that we may at least log the error and gracefully
shutdown other portions of the app.

* Updates package description to note that blockchain now takes
  2+ GB instead of 150+ MB.

Acquire an exclusive, advisory lock before sending output to debug.log
and release it when we're done. This should avoid output from multiple
threads being interspersed in the log file.

We can't use CRITICAL_SECTION machinery for this because the debug log
is written during startup and shutdown when that machinery is not
available.

(Thanks to Gavin for pointing out the CRITICAL_SECTION problems based
on his earlier work in this area)

Upstream commit: 7cfbe1fee465e82ddbdc8ed17dfcce791bd765f5

This caused clients to reject block #177618 since it has a P2SH transaction with over 200 bytes in scriptSig.

(Upstream commit: e679ec969c8b22c676ebb10bea1038f6c8f13b33)

This contributed to an accidental send (#1384), and has no clear advantage, better to disable it.

Former code sent '0' as nonce, which was serialized as 32-bit.

Old log message:

New log message:
	storing orphan tx df2244f6bc (mapsz 51)

Also, trim a few trailing whitespace in main.cpp.

Changes suggested by Sergio Demian Lerner to
help prevent potential DoS attacks.

Remove orphan transactions from memory once
all of their parent transactions are received
and they're still not valid.
Thanks to Sergio Demian Lerner for suggesting this fix.

Loop over all inputs doing inexpensive validity checks first,
and then loop over them a second time doing expensive signature
checks. This helps prevent possible CPU exhaustion attacks
where an attacker tries to make a victim waste time checking
signatures for invalid transactions.

Create a maximum-10MB signature verification result cache.
This should almost double the number of transactions that
can be processed on a given CPU, because before this change
ECDSA signatures were verified when transactions were added
to the memory pool and then again when they appeared in
a block.

* This is safer than DB_TXN_NOSYNC, and does not appear to impact
  performance.
* Applying this to the dbenv is necessary to avoid many fdatasync(2)
  calls on db 5.x
* We carefully and thoroughly flush databases upon shutdown and
  other important events already.

rather than at each include site.

Fixes #1371

More than doubles the speed of verifying already-cached signatures
that use compressed pubkeys:
Before: ~200 microseconds
After:  ~80 microseconds
(no caching at all: ~3,300 microseconds per signature)

Also encapsulates the signature cache code in a class
and fixes a signed/unsigned comparison warning.

exception, crashing the entire bitcoin process.  Properly return an
error instead, so that we may at least log the error and gracefully

In LoadExternalBlockFile(), errors are already caught... silently.
Add a warning message, even though we do not abort the program due to
load error.

Former code sent '0' as nonce, which was serialized as 32-bit.

This reverts commit 1179f6373dfffdcb091576215cabe73c932df925.

        Fix an issue where a block previously failing duplicate
        proof-of-stake check was not asked for again

        Also fixes an issue in 4bb99fbc where prev block should be asked for

        (Revert the MIN_PROTO_VERSION change from merge commit 0561bbd)

        Max 4 hours trailing checkpoint from latest block

        Enter safe mode when sync-checkpoint is too old
        Enter safe mode with high priority alert

        Windows build instruction with miniupnp client library

        Help promote proof-of-stake generation in early stages

        Wallet lock warning message for minting blocks
        Block minting suspended when wallet is locked

        as we can no longer make such a change output due to 8bb2917

        Upgrade requirements: upgrade with deadline, possible fork

        network protocol version 60002
        client version v0.2.0

        This switches the hashing protocol from a pure coin age weighted
        model more toward a coin-weighted model

        Impact: display false mismatch, no impact on wallet integrity

        Minor comment cleanup

        An issue where moneysupply resets to 0 in a racing shutdown
        An issue where moneysupply/mint could be missing with reorganization
