e91f0a7af2 doc: Remove travis badge from readme (MarcoFalke)
Pull request description:
The readme(s) are shipped in the released source-code archive, in which case the travis badge is useless since it doesn't link to the travis result of the correct commit/tag/branch. GitHub embeds the correct links for each tag or commit that ci ran on, so we don't need this link in the readme.

Pull request description:
Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.
This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.
This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.
~~Note: this builds on top of #15780.~~ (merged)

412987430c Replace OpenDebugLog() with StartLogging() (Anthony Towns)
Pull request description:
Early log messages are dropped on the floor and they'd never make it to the console or debug log. This can be tested by running the test included in this pull request without re-compiling the `bitcoind`.
Fix that by buffering early messages and flushing them as soon as all logging options have been initialized and logging has been started.
This pull request is identical to "Log early messages with -printtoconsole" (#13088) by **ajtowns**, with the following changes:
* Rebased
* Added docstrings for `m_buffering` and `StartLogging`
* Switch `CCriticalSection` (aka `RecursiveMutex`) to just `Mutex` in the last commit
* Added tests

8053e5cdad Remove -mempoolreplacement to prevent needless block prop slowness. (Matt Corallo)
Pull request description:
At this point there is no reasonable excuse to disable opt-in RBF,
and, unlike when this option was added, there are now significant
issues created when disabling it (in the form of compact block
reconstruction failures). Further, it breaks a lot of modern wallet
behavior.
This removes an option that is:
* (a) only useful when a large portion of (other) miners enforce it as well
* (b) is detrimental to everyone (income for miners, RBF notifications for others) who uses it individually otherwise
* (c) is effectively unused
* (d) is often confused with disabling RBF (rather than just remaining stubbornly unaware of it while the rest of the network lets it through)

and, unlike when this option was added, there are now significant
issues created when disabling it (in the form of compact block
reconstruction failures). Further, it breaks a lot of modern wallet
behavior.
BIP 37 bloom filters have been well-known to be a significant DoS
target for some time. However, in order to provide continuity for
SPV clients relying on it, the NODE_BLOOM service flag was added,
and left as a default, to ensure sufficient nodes exist with such a
flag.
NODE_BLOOM is, at this point, well-established and, as long as
there exist 0.18 nodes with default config (which I'd anticipate
will be true for many years), will be available from some peers. By
that time, the continued slowdown of BIP 37-based filtering will
likely have rendered it useless (though this is already largely the
case). Further, BIP 37 was deliberately never updated to support
witness-based filtering as newer wallets are expected to migrate to
some yet-to-be-network-exposed filters.

Pull request description:
When testing a combination of settings that affect the datadir (e.g. prune, blockfilter, ...) we may need a lot of datadirs.
Bump the maximum number of nodes proactively from 8 to 12, so that caches get populated with 12 node dirs, as opposed to 8.
Also, add an assert that the list of deterministic keys is exactly the number of max nodes (and not more than that.
Also, create the cache faster.

Pull request description:
(previous title "p2p: Disallow extended encoding for non-witness transactions (take 3)")
Remote peers can send us illegally encoded txs and thus have us write to stderr. Fix that by not writing to stderr.
This is a follow up to the previous (incomplete) attempts at this:
* Disallow extended encoding for non-witness transactions #14039
* Add test for superfluous witness record in deserialization #15893

utACK fa2b52af32. Would change title to something like "Avoid logging transaction decode errors to stderr" instead of "Disallow extended encoding for non-witness transactions." The current title is confusing because this PR isn't really allowing or disallowing anything, just logging the condition differently. "Disallow" also seems to contradict the "Allow exceptions from..." comments in the actual code.

This is a rebase of #11639 with some fixes for the last few comments which were not yet addressed.
The original PR text, with some strikethroughs of text that is no longer correct:
> This cleans up an old main-carryover - it made sense that main could decide what DoS scores to assign things because the DoS scores were handled in a different part of main, but now validation is telling net_processing what DoS scores to assign to different things, which is utter nonsense. Instead, we replace CValidationState's nDoS and CorruptionPossible with a general ValidationInvalidReason, which net_processing can handle as it sees fit. I keep the behavior changes here to a minimum, but in the future we can utilize these changes for other smarter behavior, such as disconnecting/preferring to rotate outbound peers based on them providing things which are invalid due to SOFT_FORK because we shouldn't ban for such cases.

Note: The change to ban all peers for consensus violations is actually NOT the change I'd like to make -- I'd prefer to only ban outbound peers in those situations. The current behavior is a bit of a mess, however, and so in the interests of advancing this PR I tried to keep the changes to a minimum. I plan to revisit the behavior in a followup PR.
EDIT: One reviewer suggested I add some additional context for this PR:
> The goal of this work was to make net_processing aware of the actual reasons for validation failures, rather than just deal with opaque numbers instructing it to do something.
>
> In the future, I'd like to make it so that we use more context to decide how to punish a peer. One example is to differentiate inbound and outbound peer misbehaviors. Another potential example is if we'd treat RECENT_CONSENSUS_CHANGE failures differently (ie after the next consensus change is implemented), and perhaps again we'd want to treat some peers differently than others.

This is a first step towards cleaning up our DoS interface - make
validation return *why* something is invalid, and let net_processing
figure out what that implies in terms of banning/disconnection/etc.
Behavior change: peers will now be banned for providing blocks
with premature coinbase spends.

Compared with previous bans, the following changes are made:
* Txn with empty vin/vout or null prevouts move from 10 DoS
points to 100.
* Loose transactions with a dependency loop now result in a ban
instead of 10 DoS points.
* Many pre-segwit soft-fork errors now result in a ban.
Note: Transactions that violate soft-fork script flags since P2SH do not generally
result in a ban. Also, banning behavior for invalid blocks is dependent on
whether the node is validating with multiple script check threads, due to a long-
standing bug. That inconsistency is still present after this commit.
* Proof of work failure moves from 50 DoS points to a ban.
* Blocks with timestamps under MTP now result in a ban, blocks
too far in the future continue to *not* result in a ban.
* Inclusion of non-final transactions in a block now results in a
ban instead of 10 DoS points.

c634b1e20 [POLICY] Make sending to future native witness outputs standard (Pieter Wuille)
Pull request description:
As discussed in the April 18 2019 IRC meeting.
This makes sending to future Segwit versions via native outputs (bech32) standard for relay, mempool acceptance, and mining. The reasons are:
* This may interfere with smooth adoption of future segwit versions, if they're defined (by the sender wallet/node).
* It violates BIP173 ("Version 0 witness addresses are always 42 or 62 characters, but implementations MUST allow the use of any version."), though admittedly this code was written before BIP173.
* It doesn't protect much, as P2SH-embedded segwit cannot be filtered in this way.
* As a general policy, the sender shouldn't care what the receiver likes his outputs to be.
Note that _spending_ such outputs (including P2SH-embedded ones) remains nonstandard, as that is actually required for softfork safety.

Pull request description:
When converttopsbt is called with a signed transaction, it either fails with "TX decode failed" if one or more inputs were segwit, or "Inputs must not have scriptSigs and scriptWitnesses" otherwise.
Since no effort is made by the test to ensure the inputs are segwit or not, avoid checking the exact message used.
The error code is still checked to ensure it is of the correct kind of failure.

Pull request description:
This introduces a new BlockFilterIndex class, which is required for BIP 157 support.
The index is uses the asynchronous BaseIndex infrastructure driven by the ValidationInterface callbacks. Filters are stored sequentially in flat files and the disk location of each filter is indexed in LevelDB along with the filter hash and header. The index is designed to ensure persistence of filters reorganized out of the main chain to simplify the BIP 157 net implementation.
Stats (block height = 565500):
- Syncing the index from scratch takes 45m
- Total index size is 3.8 GiB

d08becff8 add functional tests for feerate bumpfee with adding inputs (Gregory Sanders)
0ea47ba7b generalize bumpfee to add inputs when needed (Gregory Sanders)
Pull request description:
When targeting a feerate using `bumpfee`, call a new function that directly uses `CWallet::CreateTransaction` and coin control to get the desired result. This allows us to get a superset of previous behavior, with an arbitrary RBF bump of a transaction provided it passes the preconditional checks and spare confirmed utxos are available.
Note(s):
0) The coin selection will use knapsack solver for the residual selection.
1) This functionality, just like knapsack coin selection in general, will hoover up negative-value inputs when given the chance.
2) Newly added inputs must be confirmed due to current Core policy. See error: `replacement-adds-unconfirmed`
3) Supporting this with `totalFee` is difficult since the "minimum total fee" option in `CreateTransaction` logic was (rightly)taken out in #10390 .
