Bug #1277

Updated by Philippe Proulx 3 months ago

Hi, 

 I have a trace which cannot be opened by babeltrace as below, but I can open it with Trace Compass.

 I'm using below version. 

 <pre> 
 skim@d54030999178:~/work/tmp$ babeltrace2 -V  
 Babeltrace 2.0.4 "Amqui" 

 Amqui (/_mkwi_/) is a town in eastern Qu_bec, Canada, at the base of the Gasp_ peninsula in Bas-Saint-Laurent. Located at the confluence of the Humqui and Matap_dia Rivers, its proximity to woodlands makes it a great destination for outdoor activities such as camping, hiking, and mountain biking. 
 </pre> 

 Here is the test result which Philippe Proulx requested. 

 <pre> 
 skim@d54030999178:~/ssd_work/traces$ babeltrace2 -o ctf-metadata ./kernel | grep -A10 '^clock {' 
 </pre> 

 <pre> 
 clock { 
         name = "monotonic"; 
         uuid = "e00bcef2-1ef1-4f02-a241-8561834511fd"; 
         description = "Monotonic Clock"; 
         freq = 1000000000; /* Frequency, in Hz */ 
         /* clock value offset from Epoch is: offset * (1/freq) */ 
         offset = -48; 
 }; 
 </pre>
