# Check that stack frame deduplication only affects consecutive intervals, and
|
||
|
# that they are reported independently of any preceding sections, even if
|
||
|
# they're indistinguishable.
|
||
|
#
|
||
|
# In terms of the current implementation, we check that we clear the set of
|
||
|
# "seen frames" after eliding a group of frames.
|
||
|
#
|
||
|
# Suppose we have:
|
||
|
# - 10 frames in a function A
|
||
|
# - 10 frames in a function B
|
||
|
# - 10 frames in a function A
|
||
|
#
|
||
|
# We want to output:
|
||
|
# - a few frames of A (skip the rest)
|
||
|
# - a few frames of B (skip the rest)
|
||
|
# - a few frames of A (skip the rest)
|
||
|
#
|
||
|
# If we implemented this in the naive manner, we'd instead get:
|
||
|
# - a few frames of A (skip the rest)
|
||
|
# - a few frames of B (skip the rest, _and_ skip the remaining frames of A)
