std::unordered_map::erase( const_iterator pos ) returns an iterator to the element following the removed one. Use that to optimize (probably minor-performance-wise, and definitely code-structure-wise) the implementation of CCoinsViewCache::BatchWrite().
Use C++11's better capability of expressing an interface of a non-copyable class by publicly deleting its copy ctor and assignment operator instead of just declaring them private.
1444c2e Switch memory_cleanse implementation to BoringSSL's to ensure memory clearing even with link-time optimization. (Adam Langley)
Pull request description:
The implementation we currently use from OpenSSL prevents the compiler from optimizing away clensing operations on blocks of memory that are about to be released, but this protection is not extended to link-time optimization. This commit copies the solution cooked up by Google compiler engineers which uses inline assembly directives to instruct the compiler not to optimize out the call under any circumstances. As the code is in-lined, this has the added advantage of removing one more OpenSSL dependency.
Regarding license compatibility, Google's contributions to BoringSSL library, including this code, is made available under the ISC license, which is MIT compatible.

assumevalid.py would try to send over a closed P2P connection in a loop,
hitting the following failure many times:
TestFramework.mininode (ERROR): Cannot send message. No connection to node!
The test still passes, but this is a lot of noise in the test log.
Just check that the connection is open before trying to send.
- Move comment about transaction/block weight calculation so it applies not only to the GetBlockWeight function but also to GetTransactionWeight
- Fix comment in validation.cpp referencing future deployment of BIP113. It has already been deployed.
- The doc comment for BLOCK_DOWNLOAD_WINDOW wasn't updated since pruning was introduced, so it still refers to pruning as something that might happen in the future. A larger BLOCK_DOWNLOAD_WINDOW window would now, indeed, make pruning harder.
Make the non-const overload of CBlockIndex::GetAncestor() reuse the const overload implementation instead of the other way around. This way, the constness of the const overload implementation is guaranteed. The other way around, it was possible to implement the non-const overload in a way which mutates the object, and since that implementation would be called even for const objects (due to the reuse), we would get undefined behavior.
cdaf3a1 Fix Qt 0.14.2->0.15.0 segfault if "total at least" is selected (Matt Corallo)
Pull request description:
`QButtonGroup->button()` may return a nullptr.
Accessing the object directly with `setChecked` seems fragile.
This is a simple fix to ensure to never call a button out of bounds (nullptr).
There are probably other places where a sanity check for `QSettings` are required.

Pull request description:

As @dooglus pointed out, `g_connman` is uninitialized when an invalid wallet path is passed on start up, but then dereferenced in `Shutdown()`, so this tiny PR just fixes that.

Lint checks should not test these, they are historical documents,

a checker.
Hopefully makes travis pass again on master.

This adds a new CHECK_DOC check that looks for newly introduced trailing
whitespace. Existing trailing whitespace (of which there is plenty!)
will not trigger an error.
This is written in a generic way so that new lint-*.sh scripts can be
added to contrib/devtools/, as I'd like to contribute additional lint
checks in the future.
77aa9e59e test: Check RPC argument mapping (Wladimir J. van der Laan)
Pull request description:
Parse the dispatch tables from the server implementation files, and the conversion table from the client (see #10751).
Perform the following consistency checks:
- Arguments defined in conversion table, must be present in dispatch table. If not, it was probably forgotten to add them to the dispatch table, and they will not work.
- Arguments defined in conversion table must have the same names as in the dispatch table. If not, they will not work.
- All aliases for an argument must either be present in the conversion table, or not. Anything in between means an oversight and some aliases won't work.
Any of these results in an error.
It also performs a consistency check to see if the same named argument is sometimes converted, and sometimes not. E.g. one RPC call might have a 'verbose' argument that is converted,
another RPC call might have one that is not converted. This is not necessarily wrong, but points at a possible error (as well as makes the API harder to memorize) - so it is emitted as a warning (could upgrade this to error).
This test is added to travis and run when `CHECK_DOC`. Currently fails with the following output:
```
* Checking consistency between dispatch tables and vRPCConvertParams
ERROR: createrawtransaction argument 3 (named optintorbf in vRPCConvertParams) is not defined in dispatch table
ERROR: getblock argument ['verbosity', 'verbose'] has conflicts in vRPCConvertParams conversion specifier [True, False]
WARNING: conversion mismatch for argument named verbose ([('getblock', False), ('getblockheader', True), ('getmempoolancestors', True), ('getmempooldescendants', True), ('getrawmempool', True), ('getrawtransaction', True)])
```
- ~#10698 fixes the first ERROR~
- #10747 fixes the second ERROR, as well as the WARNING
Update: #10698 was merged, leaving:
```

Because the poll/select loop may pause for 100msec before actually doing a
send, and we have no way to force the loop awake, try sending from the calling
thread if the queue is empty.
Also, disable nagle as all sends should be either full messages or unfinished
sends.
This shaves an average of ~1 minute or so off of my accumulated runtime, and
10-15 seconds off of actual runtime.
0063d2c3d [tests] Make p2p-leaktests.py more robust (John Newbery)
Pull request description:
There has been an example of p2p-leaktests.py failing on travis in the new service bits test (introduced in #11001 . It appeared to me that the previous p2p connections had not been fully disconnected before attempting to add new p2p connections.
I've added a sleep and restarted the NetworkThread, but I don't know whether this will fix the problem, since I'm unable to reproduce the failure locally.
@MarcoFalke - not sure what you want to do here? I don't think this change could make things any worse.

In an abundance of caution this restores "Bitcoin Developers" to the COPYING file in
case there were contributors before that point in time that would object to the
current label. It's harmless and more pedantically correct.

Combine fLimitFree and fOverrideMempoolLimit into a single boolean:
bypass_limits. This is used to indicate that mempool limiting based on feerate
should be bypassed. It is used when readding transactions from a reorg and then
the mempool is trimmed to size after all transactions are added and they can be
evaluated in the context of their descendants. No changes to behavior.

ba206d2c6 Deprecate confusing blockmaxsize, fix getmininginfo output (Matt Corallo)
Pull request description:
No sensible user will ever keep the default settings here, so not
having sensible defaults only serves to screw users who are
paying less attention, which makes for terrible defaults.
Additionally, support for block-size-limiting directly has been removed:
* This removes block-size-limiting code in favor of GBT clients
doing the limiting themselves (if at all).
* -blockmaxsize is deprecated and only used to calculate an implied
blockmaxweight, addressing confusion from multiple users.
* getmininginfo's currentblocksize return value was returning
garbage values, and has been removed, also removing a
GetSerializeSize call in some block generation inner loops and
potentially addressing some performance edge cases.

We were saving a div by caching the inverse as a float, but this
ended up requiring a int -> float -> int conversion, which takes
almost as much time as the difference between float mul and div.
There are lots of other more pressing issues with the bench
framework which probably require simply removing the adaptive
iteration count stuff anyway.
No sensible user will ever keep the default settings here, so not
having sensible defaults only serves to screw users who are
