13:51 timotimo god damn it, jnthn
13:52 timotimo i was debugging why my stuff won't work
13:52 timotimo then i found out the text in the template is "PROFIELR_OUTPUT"
13:54 tadzik :D
13:55 tadzik p6profiler-qt now has progressbars all over the place
14:00 timotimo i'm working on a patch that'll let you provide a --profile-filename=test.json and it won't output the html around the json blob
14:00 timotimo the code works, but isn't that pretty to look at ATM
14:27 jnthn So typo!
14:27 jnthn Sorry, timotimo!
14:27 jnthn It was probably 2am or something when I was doing that part, and I probably just copy-psated the thing :)
14:31 timotimo :))
14:31 timotimo yes, and i re-typed it into my "new" code
14:48 timotimo hooray, we're writing out the json blob
14:59 jnthn :)
14:59 timotimo 200 MB of profile data written ...
15:00 jnthn o.O
15:00 timotimo best thing: with the "write directly" approach, the cpu usage is above 90%
15:00 timotimo hm. nearly 90%
15:00 timotimo jnthn: it's the core setting compilation (minus optimize)
15:00 timotimo you'd expect that to be huge
15:04 timotimo i forgot to put a "time" in front, i think
15:04 timotimo :S
15:06 brrt joined #moarvm
15:07 timotimo hmm. i still see many, many brk calls with ever growing addresses
15:21 timotimo i wonder what keeps growing the heap
15:22 timotimo 500 megabytes of profile dump
15:24 timotimo between 200 and 250 kilobytes per seconds being written
15:55 timotimo huh, the frequency of brk calls has increased significantly
16:07 timotimo one gig of profiler data written
16:08 nwc10 the only way I was able to profile Test::Harness for the perl core tests was to add compression to Devel::NYTProf
16:08 nwc10 this might be what you need here
16:20 timotimo we do want a sort of compression for the profiler
16:20 timotimo but that's more a semantic compression, not really a regular data compression

18:20 nwc10 current bytecode version is "4", but we seem to have code supporting back to 2
18:20 nwc10 can 2 and 3 go?
18:22 jnthn I think so.
18:22 jnthn We already updated serialization version
18:22 jnthn So there's no way you can run any really old anyway
18:23 nwc10 that was my assumption - anything that old will have too old a serialization blob
