There was a problem hiding this comment.
State::PARTIALLY_DOWNLOADED should be redundant in this place.
Let's update the file segment state in completeImpl right before this line
ClickHouse/src/Common/FileSegment.cpp
Line 565 in 5801de7
to
State::PARTIALLY_DOWNLOADED_NO_CONTINUATION if it is not already.

Changelog entry:
In FileSegmentsHolder::~FileSegmentsHolder(), when a segment is set to detach, it will assert its state is empty. However, in FileSegment::completeImpl(), when detach is set to true, its state may be PARTIALLY_DOWNLOADED_NO_CONTINUATION or SKIP_CACHE or PARTIALLY_DOWNLOADED, thus cause error in FileSegmentsHolder::~FileSegmentsHolder().
