| 182 <td colspan=2><tt>Represents an interaction that took p
lace during a timeline recording.<br> | |
| 183 <br> | |
| 184 As a page runs, typically a number of di
fferent (simulated) user interactions<br> | |
| 185 take place. For instance, a user might click&
nbsp;a button in a mail app causing a<br> | |
| 186 popup to animate in. Then they might press&nb
sp;another button that sends data to a<br> | |
| 187 server and simultaneously closes the popup without
an animation. These are two<br> | |
| 188 interactions.<br> | |
| 189 <br> | |
| 190 From the point of view of the page, each
interaction might have a different<br> | |
| 191 label: ClickComposeButton and SendEmail, for instance.&
nbsp;From the point<br> | |
| 192 of view of the benchmarking harness, the labe
ls aren't so interesting as what<br> | |
| 193 the performance expectations are for that interact
ion: was it loading<br> | |
| 194 resources from the network? was there an anim
ation?<br> | |
| 195 <br> | |
| 196 Determining these things is hard to do, simpl
y by observing the state given to<br> | |
| 197 a page from javascript. There are hints, for&
nbsp;instance if network requests are<br> | |
| 198 sent, or if a CSS animation is pending.
But this is by no means a complete<br> | |
| 199 story.<br> | |
| 200 <br> | |
| 201 Instead, we expect pages to mark up the
timeline what they are doing, with<br> | |
| 202 label and flags indicating the semantics of t
hat interaction. This<br> | |
| 203 is currently done by pushing markers into the
console.time/timeEnd API: this<br> | |
| 204 for instance can be issued in JS:<br> | |
| 205 <br> | |
| 206 var str = 'Interaction.SendEmail';<br> | |
| 207 console.time(str);<br> | |
| 208 setTimeout(function() {<br> | |
| 209 console.timeEnd(str);<br> | |
| 210 }, 1000);<br> | |
| 211 <br> | |
| 212 When run with perf.measurements.timeline_based_measurement r
unning, this will<br> | |
| 213 then cause a <a href="#TimelineInteractionRecord">TimelineInterac
tionRecord</a> to be created for this range w
ith<br> | |
| 214 all metrics reported for the marked up 1000ms
time-range.<br> | |
| 215 <br> | |
| 216 The valid interaction flags are:<br> | |

sp;to use the same label<br> </tt></td></tr> | |

| 224 There are two cases :<br> | |

| 226 Case 1: timeline_slice runs in the same threa

| 232 &n
bsp; (relative order in thread time)<
br> | |
| 233 <br> | |
| 234 As the thread timestamps in timeline_slice&
nbsp;and record are consistent, we<br> | |
| 235 simply use them to compute the overlap
.<br> | |
| 236 <br> | |
| 237 Case 2: timeline_slice runs in a different th
read from the record's.<br> | |
| 238 <br> | |

| 249 Unlike case 1, thread timestamps of a&
nbsp;thread are measured by its<br> | |
| 250 thread-specific clock, which is inconsistent&nbs
p;with that of the other<br> | |
| 251 thread, and thus can't be used to 
;compute the overlapped thread duration.<br> | |
| 252 Hence, we use a heuristic to compute&n
bsp;the overlap (see<br> | |
