- I know that a lot of folks have their own parsers for our current GC<br>
log formats. Would you be happy if we provided you with a (reliable!)<br>
parser for the new format in Java that you can easily adapt?<br></blockquote><div><br></div><div>+1. Or +10.</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

B. Introducing "cyclic" GC logs.<br>Specific questions: </blockquote><div>[snip] </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">- Would people really hate it if HotSpot starts appending the GC log</blockquote>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
file name with a (zero-padded) sequence number? Maybe if N == 1 (the<br>
default), HotSpot will skip the sequence number and ignore S, i.e.,<br>
behave as it does today.</blockquote><div><br></div><div>How many digits in the sequence?

- To the people who have been asking for cyclic GC logs: is the sequence<br>
number scheme above good enough?<br>
