It includes the following policy changes:
* All GetRand* functions seed the stack pointer and rdrand result
(in addition to the performance counter)
* The periodic entropy added by the idle scheduler now seeds stack pointer,
rdrand and perfmon data (once every 10 minutes) in addition to
just a sleep timing.
* The entropy added when calling GetStrongRandBytes no longer includes
the once-per-10-minutes perfmon data on windows (it is moved to the
idle scheduler instead, where latency matters less).
Other changes:
* OpenSSL is no longer seeded directly anywhere. Instead, any generated
randomness through our own RNG is fed back to OpenSSL (after an
additional hashing step to prevent leaking our RNG state).
* Seeding that was previously done directly in RandAddSeedSleep is now
moved to SeedSleep(), which is indirectly invoked through ProcRand
from RandAddSeedSleep.
* Seeding that was previously done directly in GetStrongRandBytes()
is now moved to SeedSlow(), which is indirectly invoked through
ProcRand from GetStrongRandBytes().
This guarantees that OpenSSL is initialized properly whenever randomness
is used, even when that randomness is invoked from global constructors.
Note that this patch uses Mutex directly, rather than CCriticalSection.
This is because the lock-detection code is not necessarily initialized
during global constructors.
89282379ba threads: fix unitialized members in sched_param (Cory Fields)
Pull request description:
Rebased theuni's #14342.
Building with gcc 8.2 against musl libc, which apparently has more attributes available in its sched_param. The following warnings were produced:
warning: missing initializer for member 'sched_param::sched_ss_low_priority' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_repl_period' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_init_budget' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_max_repl' [-Wmissing-field-initializers]
Since the current thread may have interesting non-zero values for these fields, we want to be sure to only change the intended one. Query and modify the current sched_param rather than starting from a zeroed one.

These are separate events which need to be carried out by separate subsystems.
This also cleans up some whitespace and tabs in qt to avoid getting flagged by

Currently a new node creates an unused `blocks\` directory in the root of the data directory when `-testnet` or `-regtest` is specified.

fb3ce75807 Don't label transactions "Open" while catching up (Hennadii Stepanov)
Pull request description:
Fix#13299.
Since the default `nSequence` is `0xFFFFFFFE` and locktime is enabled, the checking `wtx.is_final` is meaningless until the syncing has completed (ref: #1026).
This PR makes the wallet mark a transaction "Unconfirmed" instead of misleading "Open for NNN more blocks" when syncing after a period of being offline.

Pull request description:
Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.

There was only one place in the codebase where we're directly reading >32 bytes from
the RNG. One possibility would be to make the built-in RNG support large reads, but
using FastRandomContext lets us reuse code better.
There is no change in behavior here, because the FastRandomContext constructor
uses GetRandBytes internally.
9d0e52834 implements different disk sizes for different networks on intro (marcoagner)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/13213.
Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.
Two points:
- The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
- Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?
Thanks!

fa48baf23e wallet: Avoid leaking locktime fingerprint when anti-fee-sniping (MarcoFalke)
453803adc9 [test] wallet_txn_clone: Correctly clone txin sequence (MarcoFalke)
Pull request description:
The wallet sets the locktime to the current height of our active chain. This is fine, as long as our node is connected to other nodes. However, when we fall back and get stuck at a particular height (e.g. taking the wallet offline), the same (potentially unique) locktime is used for all transactions. This makes it easier for passive observers to cluster transactions by wallet.
For reference, I visualized "locktime-reuse" with the data:
* blocks 545k-555k (both inclusive)
* locktimes<=60k
* excluding coinbase txs

ca126d490b Fix out-of-bounds write in case of failing mmap(...) in PosixLockedPageAllocator::AllocateLocked (practicalswift)
Pull request description:
`mmap(...)` returns `MAP_FAILED` (`(void *) -1`) in case of allocation failure.
`PosixLockedPageAllocator::AllocateLocked(...)` did not check for allocation failures prior to this PR.
Instead the invalid memory address `(void *) -1` (`0xffffffffffffffff`) was passed to the caller as if it was a valid address.
After some operations the address is wrapped around from `0xffffffffffffffff` to `0x00000003ffdf` (`0xffffffffffffffff + 262112 == 0x00000003ffdf`);
The resulting address `0x00000003ffdf` is then written to.

Pull request description:
For constructing test scripts, use `std::vector` and, in particular, `std::vector::insert` to insert 20 zero bytes rather than listing the full array of bytes explicitly.

Motivated by https://github.com/bitcoin/bitcoin/pull/11913#discussion_r157798157, this pull makes `blockToJSON` and `blockheaderToJSON` free of `cs_main` locks.
Locking `cs_main` was required to access `chainActive` in order to check if the block was in the chain and to retrieve the next block index.
With the this approach, `CBlockIndex::GetAncestor()` is used in a way to check if the block belongs to the specified chain tip and, at the same time, get the next block index.

Pull request description:
When verifying blocks at startup, the progress is printed in 10% increments to logs. When `-checklevel=4`, however, the second half of the verification (connecting the blocks again) does not log the progress anymore. (It is still computed and shown in the UI, but not printed to logs.)
This change makes the behaviour consistent, by adding the missing progress logging also for level-4 checks.

c8d9d9093b Fix broken notificator on GNOME (Hennadii Stepanov)
Pull request description:
Fix#14994; that bug was introduced in #14228 (that was my fault).
~Also this commit explicit separates~ There are two functions of the tray icon:
- a system tray widget (`QSystemTrayIcon::isSystemTrayAvailable() == true`)
- a high-level notificator via balloon messages (`QSystemTrayIcon::supportsMessages() == true`)
~These properties are mutually independent,~ e.g., on Fedora 29 + GNOME:
```
QSystemTrayIcon::isSystemTrayAvailable() == false;
QSystemTrayIcon::supportsMessages() == true;
```
UPDATE:
`supportsMessages()` makes no sense without `isSystemTrayAvailable()`: `QSystemTrayIcon::showMessage()` just not working on Fedora 29 + GNOME.

Pull request description:
Salvaged (but slightly modified) from #12138, the comment there was really helpful to wrap my head around that part of the code.
In addition, a naive reader like yours truly will first think `IsValid(BLOCK_VALID_SCRIPTS)` means the previous block was invalid. But IIUC that's not what it means. Instead, it means the block hasn't been checked for validity at the `BLOCK_VALID_SCRIPTS` level yet. So in that case the existing text "previous block index isn't valid" is wrong.

Pull request description:
The current helptext for `listtransactions`, `listsinceblock` and `gettransaction` only list two of the five possible options for `category`.

Also, some of the documentation is incorrect when specifying which options are returned for which categories.
This PR updates the helptext for these RPCs and adds a functional regression test for the cases when the other three categories are returned.

This makes the above constructor explicit. The rationale is that this conversion has very significant performance effects. Making it explicit makes it easier to reason about these performance trade-offs, and helps identify possible functions that need a CMutableTransaction version.
This commit makes the minimal changes necessary to fix compilation once CTransaction(const CMutableTransaction &tx) is made explicit. In each case an explicit call `CTransaction(...)` was added. Shouldn't affect behaviour or performance.

This improves a few minor issues with the RNG code:
* Avoid calling `GetRand*()` functions (which currently invoke OpenSSL, later may switch to using our own RNG pool) inside loops in addrman, networking code, `KnapsackSolver`, and `LimitOrphanSize`
* Fix a currently unreachable bug in `FastRandomContext::randbytes`.
* Make a number of simplifications to the unit tests' randomness code (some tests unnecessarily used their own RNG or the OpenSSL one, instead of using the unit test specific `insecure_rand_ctx`).
* As a precaution, make it illegal to copy a `FastRandomContext`.

Pull request description:
By indicating the password hashing algorithm, users of bitcoin distributions without the script in `share/rpcauth` and users who don't want to rely on said script can use alternative means to generate the password hash.
Question for reviewers: perhaps we should also indicate that it is specifically a HMAC-SHA-256 of the _**UTF-8**_ encoding of their password?

This introduces various changes to the importmulti logic:
* Instead of processing input and importing things at the same time, first
process all input data and verify it, so no changes are made in case of
an error.
* Verify that no superfluous information is provided (no keys or scripts
that don't contribute to solvability in particular).
* Add way more sanity checks, by means of descending into all involved
scripts.
8db0c3d42b Removed implicit CTransaction conversion from benchmaks (lucash-dev)
ed61abedb2 Removed implicit CTransaction constructor from tests (lucash-dev)
Pull request description:
This PR was split from #14906 and is a prerequisite for it.
It updates tests and benchmarks, removing all implicit calls to `CTransaction(CMutableTransaction&)` constructors. This will make possible making the constructor explicit in the next PR.
The original rationale for making the constructor explicit:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

6be0fb4b3 [refactor] Add a base DescriptorImpl with most common logic (Pieter Wuille)
Pull request description:
This patch modifies the internal `Descriptor` class to optionally construct and use an "expansion cache". Such a cache is a byte array that encodes all information necessary to expand a `Descriptor` a second time without access to private keys, and without the need to perform expensive BIP32 derivations. For all currently defined descriptors, the cache simply contains a concatenation of all public keys used.
This is motivated by the goal of importing a descriptor into the wallet and using it as a replacement for the keypool, where it would be impossible to expand descriptors if they use hardened derivation.

02e1e4eff6 rpc: Add wait argument to stop (João Barbosa)
Pull request description:
Fixes#11777. Reverts #11006. Replaces #13501.
With this change the HTTP server will exit gracefully, meaning that all requests will finish processing and sending the response, even if this means to wait more than 2 seconds (current time allowed to exit the event loop).
Another small change is that connections are accepted even when the server is stopping, but HTTP requests are rejected. This can be improved later, especially if chunked replies are implemented.
Briefly, before this PR, this is the order or events when a request arrives (RPC `stop`):
1. `bufferevent_disable(..., EV_READ)`
2. `StartShutdown()`
3. `evhttp_del_accept_socket(...)`
4. `ThreadHTTP` terminates (event loop exits) because there are no active or pending events thanks to 1. and 3.
5. client doesn't get the response thanks to 4.
This can be verified by applying
```diff
// Event loop will exit after current HTTP requests have been handled, so
// this reply will get back to the client.
StartShutdown();
+ MilliSleep(2000);
return "Bitcoin server stopping";
}
```
and checking the log output:
```
Received a POST request for / from 127.0.0.1:62443

```
For this reason point 3. is moved right after all HTTP workers quit. In that moment HTTP replies are queued in the event loop which keeps spinning util all connections are closed. In order to trigger the server side close with keep alive connections (implicit in HTTP/1.1) the header `Connection: close` is sent if shutdown was requested. This can be tested by
```
bitcoind -regtest
nc localhost 18443
POST / HTTP/1.1
Authorization: Basic ...
Content-Type: application/json
Content-Length: 44
{"jsonrpc": "2.0","method":"stop","id":123}
```
Summing up, this PR:
- removes explicit event loop exit — event loop exits once there are no active or pending events
- changes the moment the listening sockets are removed — explained above
- sends header `Connection: close` on active requests when shutdown was requested which is relevant when it's a persistent connection (default in HTTP 1.1) — libevent is aware of this header and closes the connection gracefully
- removes event loop explicit break after 2 seconds timeout
