[lucene] branch branch_9x updated (15a403404b7 -> e1b331acef7)
This is an automated email from the ASF dual-hosted git repository.
kwright pushed a change to branch branch_9x
in repository https://gitbox.apache.org/repos/asf/lucene.git
from 15a403404b7 Invert error-prone configuration to be allow-list vs deny-list (#11970)
new ed6dfeb1d6a Refactor, in preparation for using b-trees to enhance performance.
new ab7cb2924d7 Fix formatting
new d8c9b943201 Add node structures and fast operations for them.
new 9450f3d2b64 Fix longstanding bug in path bounds calculation, and hook up efficient isWithin() and distance logic
new 177a33b79b8 Fix up formatting
new d830aee2842 fixed boxed equality check to unbreak the build: has this code been tested????
new 675d9cedd84 Revert the change the relies on accurate bounds from path components. This caused randomized test failures, and fixing the bounds caused other (inexplicable) test failures. More research needed.
new 83a81262b85 Refactor and make hierarchical GeoStandardPath. Some tests fail and will need to be researched further.
new 7540c281b07 Cleanup StandardGeoPath to get rid of unused member arrays
new fe62787386a Fix nearestDistance for real this time
new 8cdb270b090 All tests fixed saved two - distance related.
new ec97f1da35c Make sure use of aggregation form is consistent throughout, and fix segment endpoint computations of nearestDistance.
new 6063436c55b Final bugs fixed, except remaining legacy issue with nearest distance in GeoDegeneratePath.
new cf30d2bc54f Resolve conflicts
new 90b3a373ce1 More tidying to make lint happy
new 21fb195073f Fix the boxing issue again.
new df377f94e7d More work related to 11965: Improve performance of nearestDistance queries somewhat by removing unnecessary code.
new 48cbcdc8140 For 11965, add structural changes that would allow intersection calls to also be O(log(n)). Disabled though because test failures are the result of enabling it - work ongoing.
new e1b331acef7 Fix problem in new Plane code
The 19 revisions listed above as "new" are entirely new to this
