4aa2508 Bugfix: Use testnet RequireStandard for -acceptnonstdtxn default (Luke Dashjr)
Pull request description:
Fixes a bug introduced in #8855
`-acceptnonstdtxn` is a valid option only for testnet/regtest (in Core), and the help message reflects that. Currently, however, it is buggy in two ways:
1. It uses mainnet to get the default value, which doesn't make sense since the option is never available for mainnet, and the only time the option is available, is when the default is the opposite.
2. It uses the value of "require standard" directly as the default for "accept non-standard transactions", but these concepts are opposites: a negation must be performed to transform one to the other.
Note the combination of these bugs results in the correct boolean output, but the logic to get there is completely wrong.

pointer literal instead of the macro NULL
90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)
Pull request description:
Since C++11 the macro `NULL` may be:
* an integer literal with value zero, or
* a prvalue of type `std::nullptr_t`
By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.
For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf
With this patch applied there are no `NULL` macro usages left in the repo:
```
$ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
0
```
The road towards `nullptr` (C++11) is split into two PRs:
* `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
* `0` → `nullptr` is handled in PR #10645 (manual)

This fixes a few cases where we should be treating a restart-after-
coinsviewdb-reset identically to a just-reset-coinsviewdb.
Thanks to @morcos for identifying the bug.
|
|
This more clearly uses fReindex vs fReset to make sure we're not
clearing our coinsdb needlessly when restarting after a reindex.
It also makes it so that restarting after shutting down mid-reindex
isn't treates specially at all during txdb loading code, as it
shouldn't be.

c0025d0 Fix segfault when shutting down before fully loading (Matt Corallo)

eda888e Fix some LoadChainTip-related init-order bugs. (Matt Corallo)
Pull request description:
This does a number of things to clean up chainstate init order,
fixing some issues as it goes:
* Order chainstate init more logically - first all of the
blocktree-related loading, then coinsdb, then
pcoinsTip/chainActive. Only create objects as needed.
* More clearly document exactly what is and isn't called in
-reindex and -reindex-chainstate both with comments noting
calls as no-ops and by adding if guards.
* Move the writing of fTxIndex to LoadBlockIndex - this fixes a
bug introduced in d6af06d68aae985436cbc942f0d11078041d121b where
InitBlockIndex was writing to fTxIndex which had not yet been
checked (because LoadChainTip hadn't yet initialized the
chainActive, which would otherwise have resulted in
InitBlockIndex being a NOP), allowing you to modify -txindex
without reindex, potentially corrupting your chainstate!
* Rename InitBlockIndex to LoadGenesisBlock, which is now a more
natural name for it. Also check mapBlockIndex instead of
chainActive, fixing a bug where we'd write the genesis block out
on every start.
* Move LoadGenesisBlock further down in init. This is a more logical
location for it, as it is after all of the blockindex-related
loading and checking, but before any of the UTXO-related loading
and checking.
* Give LoadChainTip a return value - allowing it to indicate that
the UTXO DB ran ahead of the block DB. This just provides a nicer
error message instead of the previous mysterious
assert(!setBlockIndexCandidates.empty()) error.
* Calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.
* Move all of the VerifyDB()-related stuff into a -reindex +
-reindex-chainstate if guard. It couldn't do anything useful
as chainActive.Tip() would be null at this point anyway.

RewindBlockIndex works over both chainActive - disconnecting blocks
from the tip that need witness verification - and mapBlockIndex -
requiring redownload of blocks missing witness data.
It should never have been the case that the second half is skipped
if we're about to run -reindex-chainstate.
|
|
This gives LoadChainTip a return value - allowing it to indicate that
the UTXO DB ran ahead of the block DB. This just provides a nicer
error message instead of the previous mysterious
assert(!setBlockIndexCandidates.empty()) error.
This also calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.

6b8d872 Protect SSE4 code behind a compile-time flag (Pieter Wuille)

c1ccb15 Add SSE4 based SHA256 (Pieter Wuille)
2991c91 Add SHA256 dispatcher (Pieter Wuille)
4d50f38 Support multi-block SHA256 transforms (Pieter Wuille)
Pull request description:
This adds an SSE4 assembly version of the SHA256 transform by Intel, and uses it at run time if SSE4 instructions are available, and use a fallback C++ implementation otherwise. Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`.
In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax.
This gives around a 50% speedup on the SHA256 benchmark for me.
It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.

f4d00e6 Add a discard_rate (Alex Morcos)
b138585 Remove factor of 3 from definition of dust. (Alex Morcos)
Pull request description:
The definition of dust is redefined to remove the factor of 3.
Dust is redefined to be the value of an output such that it would
cost that value in fees to (create and) spend the output at the dust
relay rate. The previous definition was that it would cost 1/3 of the
value. The default dust relay rate is correspondingly increased to
3000 sat/kB so the actual default dust output value of 546 satoshis
for a non-segwit output remains unchanged. This commit is a refactor
only unless a dustrelayfee is passed on the commandline in which case
that number now needs to be increased by a factor of 3 to get the same
behavior. -dustrelayfee is a hidden command line option.
Note: It's not exactly a refactor due to edge case changes in rounding
as evidenced by the required change to the unit test.
A discard_rate is added which defaults to 10,000 sat/kB
Any change output which would be dust at the discard_rate you are
willing to discard completely and add to fee (as well as continuing to
pay the fee that would have been needed for creating the change)
This would be a nice addition for 0.15 and I think will remain useful for 0.16 with the new coin selection algorithms in discussion, but its not crucial.
It does add translation strings, but we could (should?) avoid that by hiding the option

Note that the CScheduler thread cant be running at this point,
it has already been stopped with the rest of the init threadgroup.
Thus, just calling any remaining loose callbacks during Shutdown()
is sane.

This requires that we not access pcoinsTip in InitBlockIndex's
FlushStateToDisk (so we just skip it until later in AppInitMain)
and the LoadChainTip in LoadBlockIndex (which there is already one
later in AppinitMain, after ReplayBlocks, so skipping it there is
fine).
