fac0cf6e55 rpc: Do not advertise dumptxoutset as a way to flush the chainstate (MarcoFalke)

Pull request description:

  The help message leaks several implementation details: leveldb and flush.

  Neither of them are relevant to the end user and I don't see why we should make them part of the API contract.

692f8307fc test: add test for witness commitment index (fanquake)
06442549f8 validation: Add minimum witness commitment size constant (fanquake)

Pull request description:

  16101de5f3: Per [BIP 141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#Commitment_structure), the witness commitment structure is at least 38 bytes,
  OP_RETURN (0x6a) + 36 (0x24) + 4 byte header (0xaa21a9ed) + 32 byte
  SHA256 hash. It can be longer, however any additional data has no
  consensus meaning.

  54f8c48d6a: As per BIP 141, if there is more than 1 pubkey that matches the witness
  commitment structure, the one with the highest output index should be
  chosen. This adds a sanity check that we are doing that, which will fail
  if anyone tries to "optimize" GetWitnessCommitmentIndex() by returning
  early.

Merge #18727: test: Add CreateWalletFromFile test
7918c1b019 test: Add CreateWalletFromFile test (Russell Yanofsky)

Pull request description:

  Add unit test calling CreateWalletFromFile, which isn't currently called from other unit tests, with some basic checks to make sure it rescans and registers for notifications correctly.

  Motivation for this change was to try to write a test that would fail without the early `handleNotifications` call in ef8c6ca60767cac589d98ca57ee33179608ccda8 from https://github.com/bitcoin/bitcoin/pull/16426, but succeed with it:

  ef8c6ca607/src/wallet/wallet.cpp (L3978-L3986)

  However, writing a full test for the race condition that call prevents isn't possible without the locking changes from #16426. So this PR just adds as much test coverage as is possible now.

  This new test is also useful for https://github.com/bitcoin/bitcoin/pull/15719, since it detects the stale notifications.transactionAddedToMempool notifications that PR eliminates.

Merge #18785: Prevent valgrind false positive in rest_blockhash_by_height
fcb7261625 Prevent valgrind false positive in rest_blockhash_by_height (Russell Yanofsky)

Pull request description:

  A bad interaction between valgrind and clang 6.0.0-1ubuntu2 with -O2 optimizations makes valgrind misleadingly imply C++ code is reading an uninitialized blockheight value in `rest_blockhash_by_height` just because that's what clang optimized code is doing. The C++ code looks like:

  ```c++
  int32_t blockheight;
  if (!ParseInt32(height_str, &blockheight) || blockheight < 0) {
  ```

  while the optimized code looks like:

  ```
  0x00000000000f97ab <+123>:   callq  0x4f8860 <ParseInt32(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int*)>
  0x00000000000f97b0 <+128>:   mov    0xc(%rsp),%ebx
  0x00000000000f97b4 <+132>:   test   %ebx,%ebx
  0x00000000000f97b6 <+134>:   js     0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
  0x00000000000f97bc <+140>:   xor    $0x1,%al
  0x00000000000f97be <+142>:   jne    0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
  ```

  During the rest_interface.py test:

  eef90c14ed/test/functional/interface_rest.py (L266)

  when `height_str` is empty, `ParseInt32` returns false and `blockheight` value is never assigned. The optimized code reads the uninitialized `blockheight` value in `0xc(%rsp)` before the checking the `ParseInt32` return value in `%al`, which is harmless, but triggers the following error from valgrind:

  This is a known bad interaction between clang and valgrind. The clang optimized code is correct but valgrind has no way of knowing that accessing the uninitialized value isn't a problem. Issue has been reported previously:

  - https://bugs.llvm.org/show_bug.cgi?id=32604#c4
  - https://github.com/Z3Prover/z3/issues/972

  This commit just sets blockheight to -1 as a workaround.

  This change was originally made in 41d5d651594c6c939add7a58b7e30c97dccdf24a from #18740 to fix the travis error there (https://travis-ci.org/github/bitcoin/bitcoin/jobs/678453061#L7157) but MarcoFalke suggested https://github.com/bitcoin/bitcoin/pull/18740#discussion_r414772851 moving to a new PR, since apparently the error's been seen on travis previously

Pull request description:

  This PR introduces mempool tracking of unbroadcast transactions and periodic reattempts at initial broadcast. This is a part of the rebroadcast project, and a standalone privacy win.

  The current rebroadcast logic is terrible for privacy because 1. only the source wallet rebroadcasts transactions and 2. it does so quite frequently. In the current system, if a user submits a transaction that does not immediately get broadcast to the network (eg. they are offline), this "rebroadcast" behavior is the safety net that can actually serve as the initial broadcast. So, keeping the attempts frequent is important for initial delivery within a reasonable timespan.

  This PR aims to improve # 2 by reducing the wallet rebroadcast frequency to ~1/day from ~1/15 min. It achieves this by separating the notion of initial broadcast from rebroadcasts. With these changes, the mempool tracks locally submitted transactions & periodically reattempts initial broadcast. Transactions submitted via the wallet or RPC are added to an "unbroadcast" set & are removed when a peer sends a `getdata` request, or the transaction is removed from the mempool. Every 10-15 minutes, the node reattempts an initial broadcast. This enables reducing the wallet rebroadcast frequency while ensuring the transactions will be propagated to the network.

  For privacy improvements around # 1, please see #16698.
  Thank you to gmaxwell for the idea of how to break out this subset of functionality (https://github.com/bitcoin/bitcoin/pull/16698#issuecomment-571399346)

7918c1b019 test: Add CreateWalletFromFile test
Add unit test calling CreateWalletFromFile, which isn't currently called from
other unit tests, with some basic checks to make sure it rescans and registers
for notifications correctly.

Motivation for this change was to try to write a test that would fail without
the early `handleNotifications` call in ef8c6ca60767cac589d98ca57ee33179608ccda8
from https://github.com/bitcoin/bitcoin/pull/16426, but succeed with it:

ef8c6ca607/src/wallet/wallet.cpp (L3978-L3986)

However, writing a full test for the race condition that call prevents isn't
possible without the locking changes from #16426. So this PR just adds as much
test coverage as is possible now.

This new test is also useful for https://github.com/bitcoin/bitcoin/pull/15719,
since it detects the stale notifications.transactionAddedToMempool notifications
that PR eliminates.

fcb7261625 Prevent valgrind false positive in rest_blockhash_by_height
A bad interaction between valgrind and clang 6.0.0-1ubuntu2 with -O2
optimizations makes valgrind misleadingly imply C++ code is reading an
uninitialized blockheight value in rest_blockhash_by_height just because that's
what clang optimized code is doing. The C++ code looks like:

    int32_t blockheight;
    if (!ParseInt32(height_str, &blockheight) || blockheight < 0) {

while the optimized code looks like:

    0x00000000000f97ab <+123>:   callq  0x4f8860 <ParseInt32(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int*)>
    0x00000000000f97b0 <+128>:   mov    0xc(%rsp),%ebx
    0x00000000000f97b4 <+132>:   test   %ebx,%ebx
    0x00000000000f97b6 <+134>:   js     0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
    0x00000000000f97bc <+140>:   xor    $0x1,%al
    0x00000000000f97be <+142>:   jne    0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>

During the rest_interface.py test:

   self.test_rest_request("/blockhashbyheight/", ret_type=RetType.OBJ, status=400)

when height_str is empty, ParseInt32 returns false and blockheight value is
never assigned. The optimized code reads the uninitialized blockheight value
in 0xc(%rsp) before the checking the ParseInt32 return value in %al, which is
harmless, but triggers the following error from valgrind:

This is a known bad interaction between clang and valgrind. The clang optimized
code is correct but valgrind has no way of knowing that accessing the
uninitialized value isn't a problem. Issue has been reported previously:

    https://bugs.llvm.org/show_bug.cgi?id=32604#c4
    https://github.com/Z3Prover/z3/issues/972

This commit just sets blockheight to 0 as a workaround.

Pull request description:

  Introducing the wallet of the glorious future (again): native descriptor wallets. With native descriptor wallets, addresses are generated from descriptors. Instead of generating keys and deriving addresses from keys, addresses come from the scriptPubKeys produced by a descriptor. Native descriptor wallets will be optional for now and can only be created by using `createwallet`.

  Descriptor wallets will store descriptors, master keys from the descriptor, and descriptor cache entries. Keys are derived from descriptors on the fly. In order to allow choosing different address types, 6 descriptors are needed for normal use. There is a pair of primary and change descriptors for each of the 3 address types. With the default keypool size of 1000, each descriptor has 1000 scriptPubKeys and descriptor cache entries pregenerated. This has a side effect of making wallets large since 6000 pubkeys are written to the wallet by default, instead of the current 2000. scriptPubKeys are kept only in memory and are generated every time a descriptor is loaded. By default, we use the standard BIP 44, 49, 84 derivation paths with an external and internal derivation chain for each.

  Descriptors can also be imported with a new `importdescriptors` RPC.

  Native descriptor wallets use the `ScriptPubKeyMan` interface introduced in #16341 to add a `DescriptorScriptPubKeyMan`. This defines a different IsMine which uses the simpler model of "does this scriptPubKey exist in this wallet". Furthermore, `DescriptorScriptPubKeyMan` does not have watchonly, so with native descriptor wallets, it is not possible to have a wallet with both watchonly and non-watchonly things. Rather a wallet with `disable_private_keys` needs to be used for watchonly things.

  A `--descriptor` option was added to some tests (`wallet_basic.py`, `wallet_encryption.py`, `wallet_keypool.py`, `wallet_keypool_topup.py`, and `wallet_labels.py`) to allow for these tests to use descriptor wallets. Additionally, several RPCs are disabled for descriptor wallets (`importprivkey`, `importpubkey`, `importaddress`, `importmulti`, `addmultisigaddress`, `dumpprivkey`, `dumpwallet`, `importwallet`, and `sethdseed`).

faec063887 log: Use Join() helper when listing log categories (MarcoFalke)

Pull request description:

  This removes the global `ListLogCategories` and replaces it with a one-line member function `LogCategoriesString`, which just calls `Join`.

  Should be a straightforward refactor to get rid of a few LOC.
