Alexander Block da2f503a48 Fix largest part of GUI lockups with large wallets (#3155)
* [Qt] make sure transaction table entry gets updated after bump

* Remove unnecessary tracking of IS lock count

* Track lockedByChainLocks in TransactionRecord

* Only update record when the TX was not ChainLocked before

* Emit dataChanged for CT_UPDATED transactions

* Use plain seconds since epoch comparison in TransactionFilterProxy::filterAcceptsRow

The QDateTime::operator< calls inside TransactionFilterProxy::filterAcceptsRow
turned out to be the slowest part in the UI when many TXs are inside
the wallet. DateRoleInt allows us to request the plain seconds since epoch
which we then use to compare against dateFrom/dateTo, which are also both
stored as seconds since epoch now.

* Don't invoke updateConfirmations directly and let pollBalanceChanged handle it

* Implement AddressTableModel::labelForDestination

This one avoids converting from string to CBitcoinAddress and calling
.Get() on the result.

* Also store CBitcoinAddress object and CTxDestination in TransactionRecord

This avoids frequent and slow conversion

* Use labelForDestination when possible

This avoids unnecessary conversions

* Don't set fForceCheckBalanceChanged to true when IS lock is received

We already do this through updateTransaction(), which is also called when
an IS lock is received for one of our own TXs.

* Only update lockedByChainLocks and lockedByInstantSend when a change is possible

lockedByChainLocks can never get back to false, so no need to re-check it.
Same with lockedByInstantSend, except when a ChainLock overrides it.

* Hold and update label in TransactionRecord

Instead of looking it up in data()

* Review suggestions

* Use proper columns in dataChanged call in updateAddressBook

Dash Core staging tree 0.14.1

What is Dash?

Dash is an experimental digital currency that enables anonymous, instant 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.

For more information, as well as an immediately useable, binary version of the Dash Core software, see https://www.dash.org/get-dash/.

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.

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 OS X, 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.
