b109a1c Remove redundant nullptr checks before deallocation (practicalswift)
Pull request description:
Rationale:
* `delete ptr` is a no-op if `ptr` is `nullptr`

7963335 Fix -disablewallet default value (João Barbosa)
b411c2a Improve -disablewallet parameter interaction (João Barbosa)
Pull request description:
The first commit logs a message for each configured wallet if `-disablewallet` is set:
```
bitcoind -printtoconsole -regtest -disablewallet -wallet=foo -wallet=bar
...
WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=foo
WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=bar
```
It also moves up the `-disablewallet` check which avoids the unnecessary `-wallet` soft set.
The second commit fixes the default value of `-disablewallet`, currently the value is correct, but it should use `DEFAULT_DISABLE_WALLET`.
The third commit can be dropped or squashed, just took the opportunity to fix the coding style there.

c098c58 Wrap dumpwallet warning and note scripts aren't dumped (MeshCollider)
a38bfbc Add wallet backup text to import*, add* and dumpwallet RPCs (MeshCollider)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/11243
Adds "Requires a new wallet backup" text to `addwitnessaddress`, `importprivkey`, `importmulti`, `importaddress`, `importpubkey`, and `addmultisigaddress`. Also adds a warning to `dumpwallet` that backing up the seed alone is not sufficient to back up non-HD addresses

5ce7cb9 [net] De-duplicate connection eviction logic (Thomas Snider)
Pull request description:
While reviewing the safeguards against deliberate node isolation on the network by malicious actors, I found a good de-duplication candidate.
I think this form is much more legible (the type of `cutoffs` notwithstanding). ReverseCompareNodeTimeConnected is not included in the list since the cutoff size is a function of the remaining number of nodes in the candidate eviction set.

24a0bdd bench: prefer a steady clock if the resolution is no worse (Cory Fields)
c515d26 bench: switch to std::chrono for time measurements (Cory Fields)
Pull request description:
gettimeofday has portability issues, see for example #11558.
Regardless of large-scale clock refactors in the future, I think it's fine for bench to just use std::chrono itself.
Note that this may slightly improve bench accuracy and changes the display from tiny floats to nanosecond counts instead.

std::chrono removes portability issues.
Rather than storing doubles, store the untouched time_points. Then
convert to nanoseconds for display. This allows for maximum precision, while
keeping results comparable between differing hardware/operating systems.
Also, display full nanosecond counts rather than sub-second floats.

d61845818 Have SegWit active by default (Pieter Wuille)
4bd89210a Unit tests for always-active versionbits. (Anthony Towns)
d07ee77ab Always-active versionbits support (Pieter Wuille)
18e071841 [consensus] Pin P2SH activation to block 173805 on mainnet (John Newbery)
526023aa7 Improve handling of BIP9Deployment limits (Anthony Towns)
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.

Add missing lock in `Clear()` (`CAddrMan`).
The variable `vRandom` is guarded by the mutex `cs`.

ff35de8 [ui] Add toggle for unblinding password fields (Thomas Snider)
Pull request description:
Proposed change for adding the ability to toggle password visibility in the password dialog. This is similar to functionality in most password managers and is specifically added with the use case of password managers in mind - the password in that case is likely pasted twice into both the new password and confirm password fields.
If this is a welcome change, I am open to suggestions on rearranging the layout.

This is an alternative approach to #11534. Rather than disconnect an outbound peer when our tip looks stale, instead try to connect to an additional outbound peer.
Periodically, check to see if we have more outbound peers than we target (ie if any extra peers are in use), and if so, disconnect the one that least recently announced a new block (breaking ties by choosing the newest peer that we connected to).

97932cd rpc: further constrain the libevent workaround (Cory Fields)

A rare race condition may trigger while awaiting the body of a message.

This work-around mimics what libevent does internally once a write has started, which is what usually happens, but not always due to the processing happening on a different thread: https://github.com/libevent/libevent/blob/e7ff4ef2b4fc950a765008c18e74281cdb5e7668/http.c#L373

720d9e8fa [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)
Pull request description:
We do currently show/hide the wallet encryption RPC calls from the help if the current wallet.
In case of an encrypted wallet, `encryptwallet` is hidden and `walletpassphrasechange`, `walletpassphrasechange` and `walletlock` do appear in the help.
This is no longer ideal in case of multiwallet due to the fact that one may want help infos in order to target a specific wallet.
IMO its preferable to have a static help screen (show everything always). The currently show/hidden calls do handle the possible invalid encryption-state fine.
Fixes #11588

If our tip hasn't updated in a while, that may be because our peers are
not relaying blocks to us that we would consider valid. Allow connection
to an additional outbound peer in that circumstance.
Also, periodically check to see if we are exceeding our target number of
outbound peers, and disconnect the one which has least recently
announced a new block to us (choosing the newest such peer in the case
of tie).

3b4ac43 Rewrite p2p-acceptblock in preparation for slight behavior changes (Matt Corallo)
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.

replace with return false
b296bf1 Init: Remove redundant exit(EXIT_FAILURE) instances and replace with return false (donaloconnor)
Pull request description:
While reviewing the bitcoin code I noticed that there are a few exit(EXIT_FAILURE) at various places in the AppInit function.
This function returns to main() which will return/exit with EXIT_FAILURE so returning false instead of an explicit exit(EXIT_FAILURE) seems to be cleaner.
This PR attempts to make things a bit more consistent.
There is a subtle difference between exit() and return from main in that the exit() will not clean up any local vars but I don't think this makes a difference in this case. Using exit() might even lead to bugs in the future where the dtor of local objects are expected to be called.

This tracks the set of all known invalid-themselves blocks (ie
blocks which we attempted to connect but which were found to be
invalid). This is used to cheaply check if new headers build on an
invalid chain.
While we're at it we also resolve an edge-case in invalidateblock
on pruned nodes which results in them needing a reindex if they
fail to reorg.
|
|
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.
|
|
There is no reason to wish to store blocks on disk always just
because a peer is whitelisted. This appears to be a historical
quirk to avoid breaking things when the accept limits were added.

The variable vRandom is guarded by the mutex cs.
