81608178cf [wallet] [rpc] Remove getlabeladdress RPC
labels are associated with addresses (rather than addresses being
associated with labels, as was the case with accounts). The
getlabeladdress does not make sense in this model, so remove it.

getaccountaddress is still supported for one release as the accounts
API is deprecated.

Pull request description:

  Adds a `loadwallet` RPCs. This allows wallets to be loaded dynamically during runtime without having to stop-start the node with new `-wallet` params.

  Includes functional tests and release notes.

  Limitations:

  - currently this functionality is only available through the RPC interface.
  - wallets loaded in this way will not be displayed in the GUI.

Merge #13023: Fix some concurrency issues in ActivateBestChain()
dd435ad Add unit tests for signals generated by ProcessNewBlock() (Jesse Cohen)
a3ae8e6 Fix concurrency-related bugs in ActivateBestChain (Jesse Cohen)
ecc3c4a Do not unlock cs_main in ABC unless we've actually made progress. (Matt Corallo)

Pull request description:

  Originally this PR was just to add tests around concurrency in block validation - those tests seem to have uncovered another bug in ActivateBestChain - this now fixes that bug and adds tests.

  ActivateBestChain (invoked after a new block is validated) proceeds in steps - acquiring and releasing cs_main while incrementally disconnecting and connecting blocks to sync to the most work chain known (FindMostWorkChain()). Every time cs_main is released the result of FindMostWorkChain() can change - but currently that value is cached across acquisitions of cs_main and only refreshed when an invalid chain is explored. It needs to be refreshed every time cs_main is reacquired. The test added in 6094ce7304 will occasionally fail without the commit fixing this issue 26bfdbaddb

  Original description below
  --

  After a bug discovered where UpdatedBlockTip() notifications could be triggered out of order (#12978), these unit tests check certain invariants about these signals.

  The scheduler test asserts that a SingleThreadedSchedulerClient processes callbacks fully and sequentially.

  The block validation test generates a random chain and calls ProcessNewBlock from multiple threads at random and in parallel. ValidationInterface callbacks verify that the ordering of BlockConnected BlockDisconnected and UpdatedBlockTip events occur as expected.

5d152601e9 [wallet] [rpc] Add loadwallet RPC
The new `loadwallet` RPC method allows an existing wallet to be loaded
dynamically at runtime.

`unloadwallet` and `createwallet` are not implemented. Notably,
`loadwallet` can only be used to load existing wallets, not to create a
new wallet.

876eb64680 [wallet] Pass error message back from CWallet::Verify()
Pass an error message back from CWallet::Verify(), and call
InitError/InitWarning from WalletInit::Verify().

This means that we can call CWallet::Verify() independently from
WalletInit and not have InitErrors printed to stdout. It also means that
the error can be reported to the user if dynamic wallet load fails.

  3) add a couple more bech32 tests (mixed-case)

0bf431870e net: Serve blocks directly from disk when possible
In `ProcessGetBlockData`, send the block data directly from disk if
type MSG_WITNESS_BLOCK is requested. This is a valid shortcut as the
on-disk format matches the network format.

This is expected to increase performance because a deserialization and
subsequent serialization roundtrip is avoided.

Merge #13158: [Qt]: Improve sendcoinsdialog readability
f08a385590 [qt]: changes sendcoinsdialog's box layout for improved readability. (marcoagner)

Pull request description:

  I'm addressing two (probably duplicate) issues: https://github.com/bitcoin/bitcoin/issues/11606 and https://github.com/bitcoin/bitcoin/issues/10613.

  Some points worth noting:

  - I've tried to balance the proposed changes on both issues without going too far and remaining a bit conservative. It will be easier to improve based on suggestions where necessary.

  - I preferred to maintain a layout that doesn't ask for an address truncation because, in my view, this wallet should be conservative on this.

  - I didn't follow the idea of aligning the amounts to the right for finding it more natural (and minimalist) to read the information without having to map alignments. Additionally, that approach seems to need more `<hr />`'s (or similar) in order to help the user to map information, which ended up cluttering the box too much (specially with multiple recipients). Thus, I preferred to just give some more space between recipients. Let me know if there are better ideas on this.

  Visually, I went from this (current):

Pull request description:

  Add compile time checking for `cs_wallet` runtime locking assertions.

  This PR is a subset of #12665. The PR was broken up to make reviewing easier.

  The intention is that literally all `EXCLUSIVE_LOCKS_REQUIRED`/`LOCKS_EXCLUDED`:s added in this PR should follow either directly or indirectly from `AssertLockHeld(…)`/`AssertLockNotHeld(…)`:s already existing in the repo.

  Consider the case where function `A(…)` contains `AssertLockHeld(cs_foo)` (without
  first locking `cs_foo` in `A`), and that `B(…)` calls `A(…)` (without first locking `cs_main`):
  * It _directly_ follows that: `A(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.
  * It _indirectly_ follows that: `B(…)` should have an `EXCLUSIVE_LOCKS_REQUIRED(cs_foo)` annotation.

264c643 wallet: Reset BerkeleyDB handle after connection fails (Tim Ruffing)

Pull request description:

  According to the BerkeleyDB docs, the DbEnv handle may not be accessed
  after close() has been called. This change ensures that we create a new
  handle after close() is called. This avoids a segfault when the first
  connection attempt fails and then a second connection attempt tries to
  call open() on the already closed DbEnv handle.

  Without the patch, bitcoindd reliably crashes in the second call to `set_lg_dir()` after `close()` if
  there is an issue with the database:

Merge #13205: [tests] Remove spurious error log in p2p_segwit.py
7384a35 [tests] Remove spurious error log in p2p_segwit.py (John Newbery)

Pull request description:

  Since 265d7c44b1, when wait_until() fails,
  an error message is logged to the test framework log. This means that if
  wait_until() is called inside a try-except with the expectation that it
  will fail, a spurious error message is logged.

  wait_until() shouldn't be called with the expectation of failure. Fix
  that in p2p_segwit.py.

Pull request description:

  Revival/rebase of #11085

  Adds a new command `sethdseed` which allows you to either set or generate a new HD seed to be used. A new keypool can be generated or the original one kept and new keys added to the keypool will come from the new HD seed.

  Wallets that are not HD will be upgraded to be version FEATURE_HD_SPLIT when the `sethdseed` RPC command is used.

  I have also add some tests for this.

  Additionally `-upgradewallet` can now be used to upgrade a wallet from non-HD to HD. When it is used for such an upgrade, the keypool will be regenerated.

87fe292d89 doc: Mention disabling BIP61 in bips.md 2018-05-13 21:03:27 +02:00
Wladimir J. van der Laan
fe16dd8226 net: Add option -enablebip61 to configure sending of BIP61 notifications
This commit adds a boolean option `-enablebip61`, defaulting to `1`, that
can be used to disable the sending of BIP61 `reject` messages. This
functionality has been requested for various reasons:

- security (DoS): reject messages can reveal internal state that can be
  used to target certain resources such as the mempool more easily.

- bandwidth: a typical node sends lots of reject messages; this counts
  against upstream bandwidth. Also the reject messages tend to be larger
  than the message that was rejected.

On the other hand, reject messages can be useful while developing client
software (I found them indispensable while creating bitcoin-submittx),
as well as for our own test cases, so whatever the default becomes on the
long run, IMO the functionality should be retained as option. But that's
a discussion for later.

Merge #13221: travis: Rename the build stage "check_doc" to "lint"
3d8ae74657 travis: Rename the build stage "check_doc" to "lint" (practicalswift)

Pull request description:

  Rename the Travis build stage from `check_doc` to `lint`.

  When `check_doc` was introduced back in fa1b80db88 it was used to make sure `contrib/devtools/check-doc.py` was run only once.

  Nowadays `check_docs` is used to trigger various linting type jobs which makes the name `check_doc` a bit misleading.

dfcd9f3e6a Use a keypool of presplit keys after upgrading to hd chain split
After upgrading to HD chain split, we want to continue to use keys
from the old keypool. To do this, before we generate any new keys after
upgrading, we mark all of the keypool entries as being pre-chain
split and move them to a separate pre chain split keypool. Keys are
fetched from that keypool until it is emptied. Only then are the new
internal and external keypools used.

5c50e93d52 Allow -upgradewallet to upgradewallets to HD
Changes the maximum upgradewallet version to the latest wallet version
number, 159900. Non-HD wallets will be upgraded to use HD derivation.
Non HD chain split wallets will be upgraded to HD chain split.

If a non-HD wallet is upgraded to HD, the keypool will be entirely
regenerated.

Since upgradewallet is effectively run during a first run, all of the
first run initial setup stuff is combined with the upgrade to HD

a3ae8e6873 Fix concurrency-related bugs in ActivateBestChain
If multiple threads are invoking ActivateBestChain, it was possible to have
them working towards different tips, and we could arrive at a less work tip
than we should.  Fix this by introducing a ChainState lock which must
be held for the entire duration of ActivateBestChain to enforce
exclusion in ABC.

ecc3c4a019 Do not unlock cs_main in ABC unless we've actually made progress.
Technically, some internal datastructures may be in an inconsistent
state if we do this, though there are no known bugs there. Still,
for future safety, its much better to only unlock cs_main if we've
made progress (not just tried a reorg which may make progress).

  This disables `OP_CODESEPARATOR` in non-segwit scripts (even in an unexecuted branch), and makes a positive `FindAndDelete` result invalid. This ensures that the `scriptCode` serialized in `SignatureHash` is always the same as the script passing to the `EvalScript`.
