Subject: [PATCH 22/42] perf tools: Introduce machine__find*_thread_time()
Date: Thu, 29 Jan 2015 17:07:03 +0900	[thread overview]
Message-ID: <1422518843-25818-23-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1422518843-25818-1-git-send-email-namhyung@kernel.org>

With data file indexing is enabled, it needs to search thread based on
sample time since sample processing is done after other (task, comm and
mmap) events are processed.  This can be a problem if a session is very
long and pid is recycled - in that case it'll only see the last one.

So keep thread start time in it, and search thread based on the time.
This patch introduces machine__find{,new}_thread_time() function for
this.  It'll first search current thread rbtree and then dead thread
tree and list.  If it couldn't find anyone, it'll create a new thread.

The sample timestamp of 0 means that this is called from synthesized
event so just use current rbtree.  The timestamp will be -1 if sample
didn't record the timestamp so will see current threads automatically.
