```
The read of the uninitialized variable nLocalServices is triggered by g_connman->GetLocalServices()
in getnetworkinfo(const JSONRPCRequest& request) (net.cpp:462):
```c++
UniValue getnetworkinfo(const JSONRPCRequest& request)
{
...
if(g_connman)
obj.push_back(Pair("localservices", strprintf("%016x", g_connman->GetLocalServices())));
...
}
```
The reason for the uninitialized nLocalServices is that CConnman::Start(...) is not called
by the tests, and hence the initialization normally performed by CConnman::Start(...) is
not done.
This commit adds a method Init(const Options& connOptions) which is called by both the
constructor and CConnman::Start(...). This method initializes nLocalServices and the other
relevant values from the supplied Options object.

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.
|

This resolves a possible-assert-on-shutdown race introduced in
1f668b646806f94acd851acdbd9939c24e0492d3 when early shutdown
occurs.
Previously this was not done to avoid any cases where the
threadGroup might not exit due to a blocking thread, but at this
point the threadGroup isn't used all that much, plus Qt already
does this, and its good to keep their init/shutdown consistent.
For those curious, the threadGroup is only used in a few places:
* Its used to run the CCheckQueues in script validation, but these
use the boost mutex/condition variable primitives, so they
respect the interrupt pretty trivially.
* Its used for the import thread, which should exit rather quickly
as mostly it just calls LoadExternalBlockFile, which has an
interruption_point right before each block loaded.
* Its used in the scheduler thread, which is only used for:
* validationinterface has an effectively-dummy reference to it.
* wallet compaction, which should not last long
* addr/banlist dumping from CConnman, which should also be fast

producesignature
e222dc2 Replace ismine with producesignature check in witnessifier (Andrew Chow)
Pull request description:
Instead of using ismine to check whether an address can be spent by us, make the witness version of the script or address first and then use ProduceSignature with the DummySignatureCreator to check if we can
solve for the script.
This is to fix cases where we don't have all of the private keys (for something like a multisig address) but have the redeemscript so we can witnessify it.

efeb273 Force on-the-fly compaction during pertxout upgrade (Pieter Wuille)
Pull request description:
It seems that LevelDB tends to leave the old "per txid" UTXO entries in the database lying around for a significant amount of time during and after the per-txout upgrade. This introduces a `CompactRange` function in the database wrapper, and invokes it after every batch of updates in `CCoinsViewDB::Upgrade()`. This lowers temporary disk usage during and after the upgrade.

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.

Instead of using ismine to check whether an address can be spent by us,

This was introduced by 3192975f1d177aa9f0bbd823c6387cfbfa943610.

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

This also calls ActivateBestChain in case we just loaded the genesis

065039d [tests] Fix incorrect memory_cleanse(…) call in crypto_tests.cpp (practicalswift)

Probably the result of copy-pasting of old code where the code was operating on arrays instead of pointers.

`setenv` function is not available from the Microsoft runtime library. Need to use `_putenv_s` instead.
This solution tells the compiler to use `_putenv_s` on `WIN32` compilation (Note: this also works on 64-bit Windows instances.) and `setenv` everywhere else.
I've tested builds on Windows 10 x64 and Ubuntu 16.04 with this code.

9737572 [Qt] Use wallet 0 in rpc console if running with multiple wallets (Jonas Schnelli)
Pull request description:
Current master with multiwallet results in accessing wallet 0 in QT (send / receive / tx history / etc.), **but** the RPC console cannot access that wallet (only non-wallet commands work).
This is a quick solution to re-allow accessing the same wallet (Index 0) via RPC console in multiwallet.
The solutions design is not "state of the art" (should go over WalletModel). Ideally we work on an overall multiwallet support for the GUI (which then would remove this change).
I think we should consider this as a bugfix.
