Nhat Nguyen created LUCENE-8384:
-----------------------------------
Summary: SoftDeleteCount assertion in SoftPendingDeletes violated
Key: LUCENE-8384
URL: https://issues.apache.org/jira/browse/LUCENE-8384
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 7.4
Reporter: Nhat Nguyen
Assignee: Simon Willnauer
Fix For: 7.5., master (8.0), 7.4.1
A spinoff from LUCENE-8381. If a soft-deletes docvalues was applied to
PendingSoftDeletes already, newDelCount should be less than the softDelCount
recorded in SegmentInfo. The attached test trips an assertion in
PendingSoftDeletes.
