Hello,
When exporting a time CPU profiling .trace
with xctrace export --output foo.xml --input PATH/TO/TRACE/FILE.trace --xpath '/trace-toc/run[@number="1"]/data/table[@schema="time-sample"]
, I am unable to reconstruct the full callstack/backtrace, despite the GUI doing so.
Sample row:
<row>
<sample-time id="22" fmt="00:00.039.455">39...</sample-time>
<thread ref="2"/>
<process ref="4"/>
<core ref="14"/>
<thread-state ref="8"/>
<weight ref="9"/>
<backtrace id="23" fmt="test::test::foo ← (11 other frames)">
<process ref="4"/>
<text-addresses id="24" fmt="frag 1732">4331406713 4331406716</text-addresses>
<process ref="4"/>
<text-addresses id="25" fmt="frag 1733">4331403 ...</text-addresses>
</backtrace>
</row>
As you can see the backtrace is cropped "(11 other frames)", but according to the backtrace documentation:
In extended views, the entire symbolicated backtrace is listed.
So how to export that extended view?
Alternatively, is it possible to symbolicate the backtrace using the text-addresses
list? That question was asked a year ago without answer so far.
Best regards
