Remove the last 10 blocks one-by-one from the end of the internal linked
list of blocks, instead of rebuilding a truncated list from scratch.
(This all takes place within a write-lock anyway, so it's atomic.)
Add missing synchronisation to the 'toProtoMessage' method, by first
copying the internal list of blocks inside a read-lock, prior to
serialisation (still outside the lock, to maximise concurrency). Since
we only make a shallow copy, this should be fast and take no more than a
MB or so of extra memory.
This prevents a race seen to cause a ConcurrentModificationException
during store persistence, that sometimes occurred when the application
resumed from a long suspension.
Use 'Tx::getBurntBsq' instead of 'Tx::getBurntFee', so as not to exclude
BSQ burned by invalid txs from the supply calculations. There are no
invalid BSQ txs at present on mainchain, but accidentally burned BSQ
should definitely count as a reduction in supply, so this fixes a bug.
1. Tidy up the stream pipelines which sum over time intervals, by
summing directly with a grouping collector, instead of wastefully
collecting to an intermediate map of lists;
2. Move duplicate 'memoize' static method to the base class;
3. Factor out 'getDateFilteredMap' static method, to replace the
repeated pattern of filtering date keys by a provided predicate and
collecting into a new map;
4. Use 'Map::replaceAll' instead of the pattern:
map.entrySet().forEach(e -> e.setValue(updateFn(e.getValue())));
5. Fix a quadratic time bug in 'getBsqMarketCapByInterval' by passing an
ordered map to 'issuanceAsOfDate', so that it doesn't have to
repeatedly sort or linearly scan the entire keyset of time intervals,
to find the latest one before the provided date.
First, the AtomicFileWriter writes data to a rolling file and before
swapping the rolling file with the active file. This makes all file
writes atomic and let's Bisq recover from crashes.
Now that 'mockito-junit-jupiter' has been added to the build test
dependencies, we may replace the manual setup & tear down of a Mockito
session with the 'MockitoExtension' JUnit 5 test extension, as the old
Mockito JUnit 4 test runner was no longer available upon upgrading to
Jupiter. This slightly simplifies the tests which use '@Mock', '@Spy',
etc.
Fix inspection warnings and other minor defects (unchecked casts, bad
'assert*' usage, unused assignments/declarations, missing null checks,
object equality on enum instances, needless statement lambdas, missing
final, redundant 'toString', needless visibility) in 'TxValidatorTest'.
Also, uniformise and slightly tidy resource loading in other test
classes, replacing 'Files.readAllBytes' with Java 11 'Files.readString'
(which assumes UTF-8 as desired, instead of the default charset).
