29e983386b0aecf99cdb7d0e08ba6b450bed313e Fixes Bug in Transaction generation in ComplexMempool benchmark (Shorya) Pull request description: This fixes issues with `ComplexMempool` benchmark introduced in [#17292](https://github.com/bitcoin/bitcoin/pull/17292) , this stress test benchmarks performance of ancestor and descendant tracking of mempool graph algorithms on a complex Mempool. This Benchmark first creates 100 base transactions and stores them in `available_coins` vector. `available_coins` is used for selecting ancestor transactions while creating 800 new transactions. For this a random transaction is picked from `available_coins` and some of its outputs are mapped to the inputs of the new transaction being created. Now in case we exhaust all the outputs of an entry in `available_coins` then we need to remove it from `available_coins` before the next iteration of choosing a potential ancestor , it is now implemented with this patch. As the index of the entry is randomly chosen from `available_coins` , In order to remove it from the vector , if index of the selected entry is not at the end of `available_coins` vector , it is swapped with the entry at the back of the vector , then the entry at the end of `available_coins` is popped out. Earlier the code responsible for constructing outputs of the newly created transaction was inside the loop used for assigning ancestors to the transaction , which does some unnecessary work as it creates outputs of the transaction again and again , now it is moved out of the loop so outputs of the transaction are created just once before adding it to the final list of the transactions created. This one is a minor change to save some computation. These changes have changed the `ComplexMempool` benchmark results on `bitcoin:master` as follows : **Before** > | ns/op | op/s | err% | total | benchmark |--------------------:|--------------------:|--------:|----------:|:---------- | 232,881,625.00 | 4.29 | 0.7% | 2.55 | `ComplexMemPool` **After** > | ns/op | op/s | err% | total | benchmark |--------------------:|--------------------:|--------:|----------:|:---------- | 497,275,135.00 | 2.01 | 0.5% | 5.49 | `ComplexMemPool` Top commit has no ACKs.

What is Dash?
Dash is an experimental digital currency that enables instant, private payments to anyone, anywhere in the world. Dash uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Dash Core is the name of the open source software which enables the use of this currency.
Pre-Built Binary
For more information, as well as an immediately usable, binary version of the Dash Core software, see https://www.dash.org/downloads/.
License
Dash Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.
Development Process
The master branch is meant to be stable. Development is normally done in separate branches.
Tags are created to indicate new official,
stable release versions of Dash Core.
The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.
Testing
Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.
Automated Testing
Developers are strongly encouraged to write unit tests for new code, and to
submit new unit tests for old code. Unit tests can be compiled and run
(assuming they weren't disabled in configure) with: make check. Further details on running
and extending unit tests can be found in /src/test/README.md.
There are also regression and integration tests, written
in Python, that are run automatically on the build server.
These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py
The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
Manual Quality Assurance (QA) Testing
Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.
Translations
Changes to translations as well as new translations can be submitted to Dash Core's Transifex page.
Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.
Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
Translators should also follow the forum.
