Kyzz |
pdurbin: Or anyone else around to help me with this Java thing i've been working on |
| 02:36 |
|
Kyzz |
I'm stuck with the OOP stuff |
| 02:36 |
|
Kyzz |
more or less |

Kyzz: What do you need help with |
| 08:02 |
|
pulsar |
"this java thing" ;) |
| 08:03 |
|
pulsar |
Kyzz: dont ask to ask, post a link to a gist/pastebin/whatever snippet service |
| 08:03 |
|
pulsar |
and try to boil down your problem to one question / commented code. |
| 08:04 |
|
pulsar |
most ppl here are working and wont have much time during office hours to ask questions so you can ask yours. |

pdurbin |
Kyzz: trouble with your swing app? |
| 14:39 |
|
aditsu |
what do you guys use for java profiling? |
| 14:56 |
|
pdurbin |
netbeans |
| 14:57 |
|
aditsu |
so... visualvm? |
| 15:00 |
|
aditsu |
oh, I see there's a different netbeans-profiler package |
| 15:00 |
|
aditsu |
ah, but it's a dependency of visualvm anyway |
| 15:02 |
|
aditsu |
bah, maybe it's time to give netbeans another try |
| 15:14 |
|
pdurbin |
yeah, I'm pretty sure it's just visualvm |
| 15:17 |
|
aditsu |
I had an older visualvm installed and it doesn't seem to work very well... trying netbeans 8 now |
| 15:17 |
|
aditsu |
it's fairly pleasant so far :) let me see if I can profile something |
| 15:20 |
|
aditsu |
I'm impressed :) |
| 15:23 |
|
aditsu |
it doesn't seem to take snapshots though |
| 15:34 |
|
aditsu |
I can only see live results (hot spots), no call tree and no snapshots |
| 15:44 |
|
pdurbin |
aditsu: you can take snapshots |
| 15:45 |
|
aditsu |
I tried, it didn't do anything |
| 15:45 |
|
aditsu |
trying to run the project from netbeans now.. but it doesn't seem to have an option to redirect input |
| 15:45 |

| 15:46 |
|
aditsu |
that's what I want ^ |
| 15:47 |
|
pdurbin |
aditsu: someone in #netbeans might know |
| 15:52 |
|
aditsu |
the only "someone" seems to be you :p |
| 15:53 |
|
pdurbin |
aditsu: the netbeans community is very open to people filing issues for anything. you should feel free: https://netbeans.org/bugzilla/ |
| 15:54 |
|
aditsu |
anything? hmm, I have an issue... I don't have a million dollars :p |
| 15:55 |
|
aditsu |
anyway, I don't feel comfortable filing a bug report after using netbeans for just 30 min |
| 15:58 |
|
pdurbin |
aditsu: just do it |
| 16:06 |
|
aditsu |
ok.. if I get in trouble, I'll blame you :p |
| 16:16 |
|
pdurbin |
:) |
| 16:16 |
|
pdurbin |
aditsu: done yet? what's the bug number? |
| 16:17 |
|
aditsu |
just submitted, https://netbeans.org/bugzilla/show_bug.cgi?id=252250 |
| 16:17 |
|
pdurbin |
aditsu++ |
| 16:43 |
|
aditsu |
also added bug 252251 |
| 16:44 |
|
aditsu |
this is basic stuff, I think eclipse had it 12 years ago... |
| 16:44 |
|
aditsu |
actually.. let me double-check |
| 16:46 |
|
aditsu |
hm, maybe not, or at least it's confusing :p |
| 16:49 |
|
aditsu |
ok I was wrong, eclipse also doesn't have that option yet (but it will be in eclipse 4.5) |
| 17:15 |
|
* pdurbin |
looks at https://netbeans.org/bugzilla/show_bug.cgi?id=252251 |
| 17:15 |
|
pdurbin |
ah, about standard input |
| 17:47 |
|
aditsu |
so anyway, in the meantime, I still can't profile :p |
| 17:50 |
|
aditsu |
unless I write some code to read from a specific file, I guess |
| 17:53 |
|
pdurbin |
aditsu: can you use visualvm by itself? |
| 17:54 |
|
aditsu |
the one I have doesn't work very well.. |
| 17:54 |
|
pdurbin |
huh. dunno |
| 17:54 |
|
aditsu |
does netbeans install its own visualvm? |
| 17:54 |
|
pdurbin |
aditsu: I assume `jconsole` doesn't cut it. you want more detail |
| 17:56 |
|
aditsu |
anyway, doing System.setIn now, this might work |
| 17:57 |
|
pdurbin |
aditsu: are you troubleshooting a performance problem? |
| 17:57 |
|
aditsu |
yeah |
| 17:58 |
|
aditsu |
hmm, "take snapshot" still doesn't work! |
| 18:03 |
|
aditsu |
ooh, I think I found something |
| 18:03 |
|
aditsu |
I said "take snapshot" does nothing... that's not 100% true |
| 18:04 |
|
aditsu |
very hard to notice, but a tiny "1" bubble appears in the status bar on the right side |
| 18:04 |
|
aditsu |
when I double-click it, it shows me an unexpected exception |
| 18:05 |
|
aditsu |
StackOverflowError |
| 18:08 |
|
pdurbin |
aditsu: I found someone who might be able to help: http://irclog.greptilian.com/sourcefu/2015-05-05 |
| 18:14 |
|
aditsu |
I updated the bug report |
| 18:17 |
|
aditsu |
pdurbin: I wonder how much he can help if he can't even see I'm having a problem :p |
| 18:31 |
|
aditsu |
aha! |
| 18:31 |
|
aditsu |
I modified the -J-Xss option in netbeans.conf, and now I can get a snapshot :) |
| 18:33 |
|
aditsu |
oh jeez, the call tree is way too deep |
| 18:38 |
|
pdurbin |
I've had to drill down on some pretty deep call trees. I blame EJB. |
| 18:39 |
|
aditsu |
I blame recursion |
| 18:41 |
|
pdurbin |
heh |
| 18:46 |
|
aditsu |
I think I managed to freeze netbeans |
| 18:56 |
|
aditsu |
hm, I changed some profiling settings and now I can't take a snapshot again... with no error in the status bar |
| 19:27 |
|
aditsu |
pdurbin: do you know how to get back from back traces of a method to the call tree? |
| 19:27 |
|
aditsu |
ah nevermind, there are some tabs on the bottom of that view |
| 19:28 |

aditsu |
for some reason, it doesn't want to profile again after I stop profiling, unless I restart netbeans |
| 19:40 |
|
aditsu |
some actions are painfully slow.. |
| 19:48 |
|
pdurbin |
aditsu: are you profiling all classes? some of them? |
| 19:48 |
|
aditsu |
all |
| 19:49 |
|
pdurbin |
yeah, probably slow then |
| 20:17 |
|
aditsu |
anyway, I made a performance improvement, but it's not quite enough.. and it's hard to find the next one |
| 20:18 |
|
aditsu |
heh, netbeans has totally different shortcuts, it throws me off pretty badly :p |
| 20:19 |
|
aditsu |
ooh, it has an eclipse profile |
| 20:59 |
|
pdurbin |
netbeans isn't so bad |
| 20:59 |
|
pdurbin |
it has grown on me |
| 21:08 |
|
aditsu |
I have a disturbing feeling that the next big optimization will be switching from ArrayList to arrays |
| 21:10 |
|
pdurbin |
ah |
