748157913 [tests] Make comp test framework more debuggable (John Newbery)
Pull request description:
We should remove the comparison test framework entirely (see #10603).
Until we do that, let's make it a bit more debuggable. Currently, if there's an assert in the framework, it's very difficult to track down where we are in the test generator. Make the logging a bit better to help with debugging.

Pull request description:
Nowhere else in the protocol do we send headers which are for
blocks we have not fully validated except in response to getheaders
messages with a null locator. On my public node I have not seen any
such request (whether for an invalid block or not) in at least two
years of debug.log output, indicating that this should have minimal
impact.

Pull request description:
This is the first part of #11518. It removes a ~150 lines of unused code from the mininode module:
- remove unused `deliver_sleep_time` and `EarlyDisconnectError` code
- remove support for pre-BIP31 ping messages
- remove support for alert message
- explicitly don't support p2p versions lower than 60001
Should be an easy ACK for reviewers. If all extended tests pass, then this code really was dead :)

The mininode module includes code to support p2p versions below
60001. However, the test_framework does not support versions
of Bitcoin Core before V0.13.0. Remove code supporting
p2p versions before 60001 (which has never been run).
BIP31 support was added to Bitcoin Core in version 0.6.1. Our test
framework is incompatible with Bitcoin Core versions that old, so remove
all special logic for handling pre-BIP31 pings.
p2p connections can now be added to TestNode instances.
This commit also updates the example test to use the new
p2p interface in TestNode to demonstrate usage.
A future commit will update the existing tests to use p2p through the
TestNode.

18e071841 [consensus] Pin P2SH activation to block 173805 on mainnet (John Newbery)

Pull request description:
Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate).
This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option.
A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition.
This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.

Pull request description:
@sdaftuar pointed out that the version in #11487 was somewhat DoS-able as someone could feed you a valid chain that forked off the the last checkpoint block and force you to do lots of work just walking backwards across blocks for each new block they gave you. We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458.
Includes tests from #11487.

This is a simple change that makes our accept requirements the
same as our request requirements, (ever so slightly) further
decoupling our consensus logic from our FindNextBlocksToDownload
logic in net_processing.
Removes checking whitelisted behavior (which will be removed, the
difference in behavior here makes little sense) and no longer
requires that blocks at the same work as our tip be dropped if not
requested (in part because we *do* request those blocks).
e065249 Add unit test for outbound peer eviction (Suhas Daftuar)
5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)
Pull request description:
The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.
The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:
For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip. If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient work, we disconnect that peer.
We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.
We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split. Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect. This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.

6d51eaefe qa: Fix race condition in sendheaders.py (Suhas Daftuar)
c96b2e4f0 qa: Fix replace-by-fee race condition failures (Suhas Daftuar)
Pull request description:
I think #11407 broke replace-by-fee by introducing a race condition. I was observing frequent failures of replace-by-fee locally, always with a mempool sync failure (the sync call was added in #11407).
It appeared to me like there were two causes: sometimes the node would be in IBD and not request the transaction that was relayed; other times the blocks generated in make_utxo wouldn't have relayed quickly enough for the spend of the transaction to be accepted. I believe I've fixed both potential errors.
ping @instagibbs
Edit: I found a race condition in the sendheaders.py test, where if the verack from the python node wasn't processed before the first block in the test was generated, then no block announcement would go out to that peer, breaking the test. Fixed by adding a sync_with_ping after waiting for verack.

Make sure wallet databases have unique fileids. If they don't, throw an error.
BDB caches do not work properly when more than one open database has the same
fileid, because values written to one database may show up in reads to other
databases.
Bitcoin will never create different databases with the same fileid, but users
can create them by manually copying database files.
BDB caching bug was reported by Chris Moore <dooglus@gmail.com>

a2be3b6 [net] Ignore getheaders requests for very old side blocks (Jim Posen)
Pull request description:
Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.
