This allows a very compact notation for serialization of vectors whose
elements are not serialized using their default encoding.
|
|
|
|
Use std::move workaround for unique_ptr, for when the C++ compiler lacks
a fix for this issue:
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1579
Do this in a way that avoids a GCC 9 `-Wredundant-move` warning.
|
|
Replace the memset/strncpy dance in `CMessageHeader::CMessageHeader`
with explicit code that copies then name and asserts the length.
This removes a warning in g++ 9.1.1 and IMO makes the code more readable
by not relying on strncpy padding and silent truncation behavior.

acd644b83d789a6cdfbeda19732119534d10058e build: remove --large-address-aware linker flag (fanquake)
Pull request description:
This flag was used when building 32-bit Windows executables, which we no-longer
do, and is not accepted by the linker for any of the hosts we currently build
for. i.e:
```bash
checking whether the linker accepts -Wl,--large-address-aware... no
```
--large-address-aware
If given, the appropriate bit in the "Characteristics" field of the COFF
header is set to indicate that this executable supports virtual addresses
greater than 2 gigabytes. This should be used in conjunction with the /3GB
or /USERVA=value megabytes switch in the "[operating systems]" section of
the BOOT .INI. Otherwise, this bit has no effect. [This option is specific
to PE targeted ports of the linker]
You can check that the appropriate bit in the COFF header of our 64-bit
Windows binaries is still be set using dumpbin. i.e:
```powershell
dumpbin /headers .\bitcoind.exe
FILE HEADER VALUES
<snip>
26 characteristics
Executable
Line numbers stripped
Application can handle large (>2GB) addresses

clock_gettime(), CLOCK_MONOTONIC and CLOCK_REALTIME are all available for use on
macOS (now that we require macOS >=10.12). Use them rather than the deprecated
mach_timespec_t time API.

7e2104433cd0905ccf94632511b3ca0ce5b0463b build: use macOS 10.14 SDK (fanquake)
ca5055a5aa07aba81a87cf12f6f0526a63c423b5 depends: native_cctools 921, ld64 409.12, libtapi 1000.10.8 (fanquake)
1de8c067c74cd171144c8a900a8a20efe3072c43 depends: clang 6.0.1 (fanquake)
Pull request description:
TLDR: This updates our macOS toolchain to use a newer version of Clang, cctools (including new [dependency on libtapi](https://github.com/tpoechtrager/cctools-port/tree/master#dependencies)), LD64 and the macOS SDK.
I've been testing depends builds (`HOST=x86_64-apple-darwin16`) inside a Debian Buster [Docker container](https://github.com/fanquake/core-review/blob/master/docker/debian.dockerfile), and running the resultant `bitcoind` and `bitcoin-qt` binaries on a macOS `10.14.4` system. The `.dmg` generated by a `make deploy` also mounts correctly on the same macOS system.
#### Clang
Upgraded from `3.7.1` to [`6.0.1`](https://releases.llvm.org/6.0.1/docs/ReleaseNotes.html)
#### cctools
* cctools `877.8` -> [`921`](https://opensource.apple.com/tarballs/cctools/)
* LD64 `253.9` -> [`409.12`](https://opensource.apple.com/source/ld64/)
* TAPI [`1000.10.8`](https://opensource.apple.com/tarballs/tapi/)
See [tpoechtrager/cctools-port](https://github.com/tpoechtrager/cctools-port/) and [tpoechtrager/apple-libtapi](https://github.com/tpoechtrager/apple-libtapi/).
#### macOS SDK
Upgraded from building against the macOS `10.11` SDK to the macOS `10.14` SDK.
#### TODO
- [x] Make the `10.14` SDK available to Travis.

c0bc453135b3f549f800545075cb7bdb310c3ad4 build: remove deprecated key from macOS Info.plist (fanquake)
Pull request description:
Note that the current release binaries show correct version numbers everywhere in the GUI and macOS info dialogs (except for when you "space" click the app, shown in screenshots), and we haven't reintroduced the issue that #14701 fixed. This is just swapping a deprecated field for a newer one, as well as using the entire version string in two fields that we hadn't been previously.
Follows up discussion in #14701.

Pull request description:
<!--
*** Please remove the following help text before submitting: ***
Pull requests without a rationale and clear improvement may be closed
immediately.
-->
<!--
Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.
-->
When bitcoind is running in pruned mode, producing a hashlist with `./linearize-hashes.py linearize.cfg > hashlist.txt` and then executing `linearize-data.py linearize.cfg` will produce:
```
Read 313001 hashes
Input file /home/dan/.bitcoin/blocks/blk00000.dat
Premature end of block data
```
This happens because `linearize-data` starts by attempting to process `blk00000.dat` regardless of whether or not `blk00000.dat` actually exists - this may not be the case if working with a pruned node.
This PR adds a function which finds the first block file that does exist, and calls that function when the `BlockDataCopier` is initialized.
This is a refactor of #16431.
<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.

1abcecc40c518a98b7d17880657ec0247abdf125 Tests: Use self.chain instead of 'regtest' in almost all current tests (Jorge Timón)
Pull request description:
Simply avoiding the hardcoded string in more places for consistency.
It can also allow for more easily reusing tests for other chains other than regtest.
Separated from #8994 .
Continues #16509 .
It is still not complete (ie to be complete, we need the -chain parameter in #16680 and make whether acceptnonstdtxs is allowed for that chain or not customizable for regtest [or for custom chains like in #8994 ] ). But while being incomplete like #16509 , it's quite simple to review and another step forward IMO.

Sjors:
re-ACK 1abcecc. I think it's an improvement even if incomplete and if some PR's might accidentally bring "regtest" back. Subsequent improvements hopefully don't have to touch 16 files.

0a50019fde7781263e0c8f041d1d9dcb0dee77e8 Walk pindexBestHeader back to ChainActive().Tip() if it is invalid (Matt Corallo)
Pull request description:
Instead of keeping pindexBestHeader set to the best header we've
ever seen, reset it back to our validated tip if we find an ancestor
of it turns out to be invalid. While the name is now a bit confusing,
this matches much better with how it is used in practice, see below.
Further, this opens up more use-cases for it in the future, namely
aggressively searching for new peers in case we have discovered
(possibly via some covert channel) headers which we do not know to be
invalid, but which we cannot find block data for.
Places pindexBestHeader is used:
* Various GUI displays of the best header and getblockchaininfo["headers"],
I don't think changing this is bad, and if anything this is less confusing
in the presence of an invalid block.
* IsCurrentForFeeEstimation(): If anything I think ensuring pindexBestHeader
isn't some crazy invalid chain is better than the alternative, even in the
case where you are rejecting the current chain due to hardware error (since
hopefully in that case you won't get any new blocks anyway).
* ConnectBlock assumevalid checks: We use pindexBestHeader to check that the
block we're connecting leads to something with nMinimumChainWork (preventing
a user-set assumevalid from having bogus work) and that the block we're
connecting leads to pindexBestHeader (I'm not too worried about this one -
it's nice to "disable" assumevalid if we have a long invalid headers chain,
but I don't see it as a critical protection).
* BlockRequestAllowed() uses pindexBestHeader as its target to ensure the
requested block is within a month of the "current chain". I don't think this
is a meaningful difference, if we're rejecting the current tip we're
trivially fingerprintable anyway, and if the chain really does have a bunch
of invalid crap near the tip, using the best not-invalid header is likely a
better criteria.
* ProcessGetBlockData uses pindexBestHeader as the "current chain" definition
of whether a block request is "historical" for the purpose of bandwidth
limiting. Similarly, I don't see why this is a meaningful change.
* We use pindexBestHeader for requesting missing headers on receipt of a
headers/compact block message or block inv as well as for initial getheaders.
I think this is definitely wrong, using the best not-invalid header for such
requests is much better.
* We use pindexBestHeader to define the "current chain" for deciding when
we're close to done with initial headers sync. I don't think this is a
meaningful change.
* We use pindexBestHeader to decide if initial headers sync has timed out. If
we're rejecting the chain due to hardware error this may result in
additional cases where we ban a peer, but this is already true, so I think
its fine.

bd5a02692853f7240a4fdc593d7d0123d7916e45 Make UpdateTransactionsFromBlock use Epochs (Jeremy Rubin)
2ccb7cca4ac67198ac89bd58f5b4ae41a5163ceb Add Epoch Guards to CTXMemPoolEntry and CTxMemPool (Jeremy Rubin)
Pull request description:
UpdateTransactionsFromBlock is called during a re-org. When a re-org occurs, all of the transactions in the mempool may be descendants from a transaction which is in the pre-reorg block. This can cause us to propagate updates, worst case, to every transaction in the mempool.
Because we construct a `setEntries setChildren`, which is backed by a `std::set`, it is possible that this algorithm is `O(N log N)`.
By using an Epoch visitor pattern, we can limit this to `O(N)` worst case behavior.
Epochs are also less resource intensive than almost any set option (e.g., hash set) because they are allocation free.
This PR is related to https://github.com/bitcoin/bitcoin/pull/17268, it is a small subset of the changes which have been refactored slightly to ease review. If this PR gets review & merge, I will follow up with more PRs (similar to #17268) to improve the mempool

Pull request description:
This PR builds on #17578 (now merged) and deprecates the rpc getaddressinfo `label` field. The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=label`.
See http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622 and https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001 for more context.
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=label` flag while verifying the rpc getaddressinfo output and help text.
Next step: add support for multiple labels.

a029e18c2bf67dd00552b0f4bbc85fa2fa5b973b Use rolling bloom filter of recent block tx's for AlreadyHave() check (Suhas Daftuar)
Pull request description:
In order to determine whether to download or process a relayed transaction, we first try to check whether we already have the transaction -- either in the mempool, in our filter of recently rejected transactions, in our orphan pool, or already confirmed in a block.
Prior to this commit, the heuristic for checking whether a transaction was confirmed in a block is based on whether there's a coin cache entry corresponding to the 0- or 1-index vout of the tx. While that is a quick check, it is very imprecise (eg if those outputs were already spent in another block, we wouldn't detect that the transaction has already been confirmed) -- we can do better by just keeping a rolling bloom filter of the transactions in recent blocks, which will better capture the case of a transaction which has been confirmed and then fully spent.
This should reduce the bandwidth that we waste by requesting transactions which will not be accepted to the mempool.
To avoid relay problems for transactions which have been included in a recent block but then reorged out of the chain, we clear the bloom filter whenever a block is disconnected.

Code review ACK a029e18c2bf67dd00552b0f4bbc85fa2fa5b973b also built/ran tests and am running bitcoind with mempool debug logging and custom logging. Looked a bit into CRollingBloomFilter and also the mempool median time past checks mentioned above; I don't have a deep understanding of those areas yet but the concept here and changes LGTM. Tests and other optimisations could be added as a follow-up. In favor of seeing this move forward if no major immediate concerns.
