[68cat] [news] NetCAT Status Report - 4.

[Jiri Kovalsky]

Hello NetCAT team,

   another week is gone so I am here with our regular status report. Hopefully you find it useful.

1. *Current status*

   Last week was very productive. In terms of bug income it was actually the best week so far with ~12.6 submitted bugs daily. 20 unique NetCAT members participated in discussions which generated ~13.7 e-mails sent every day on average. Feedback was not uniform at all covering variety of topics from Core through Debugger, Editor, Installer, Performance to J2EE.

2. *Important stuff*

   * NetBeans 6.8 _Milestone 2 was released_ [1] last Thursday and because it's a fully Beta quality certified build we kindly ask all of you to use it in your production development and more importantly send us your feedback. Of course if you prefer living on a bleeding edge, take daily builds instead! :-)

   [1] http://bits.netbeans.org/download/6.8/m2

   * Important thread [2] was started by David Strupl who calls for your _experience with new classpath scanning_ behavior. We have taken NetCAT 6.7 input seriously and invested a lot of effort into this area. As a result it is now possible to better use the IDE during the scanning. Please join Ulf Zibis and share your findings. Thanks!

   [2] http://www.netbeans.org/servlets/ReadMsg?list=netcat&msgNo=16938

   * Eric M. Smith noticed a significant _increase in total memory consumption_ of his NetBeans 6.8 from ~130 to ~240 MB since October 1st. Luckily no more participants confirmed this leak. Eric promised to generate a memory snapshot but most probably didn't have chance to date. Or is it back to normal Eric? :-)

   * Alied Pérez Martínez complained about very _slow stepping through his code_ during debugging session. Ulf Zibis thinks it could be related to #173405 but we would need more details from Alied himself.

   * Alied also focused on _smooth installation_ process. On one occasion he couldn't finish successful installation of a plugin. He also requested kind of an installations manager or user friendly im/exporter of installed plugins. The latter is at least possible via -J-Dplugin.manager.import.from= command line option.

   * There was also a thread about _incorrect scrolling and broken navigation_ via error stripe when automatic code folding is turned on. If you face similar problems, please speak up!

   * David Salter together with Stefan Flemming reported some _issues in J2EE_ functionality. Exceptions are thrown on editing JSPs (#172297), Facelets plugin does not install correctly or strange errors show up on IDE startup with J2EE 6 web projects opened. Guys, please report the latter issues!

   * Peter Nabbefeld is disappointed (#173828) that one has to _clone whole Mercurial repository_ even though s/he wants only a single module. Unfortunately nobody else supported Peter and we don't want to workaround this Hg limitation.

   * This call is a little off-topic here but I encourage everyone to participate in the _NetBeans Governance Board elections_ [3]. Please choose your candidate(s) and vote for them if you care about NetBeans future!

   [3] http://www.netbeans.org/community/articles/nbelections.html

3. *Bug hunting*

   * Stefan Wilfling warned us about _reproducible deadlock_ (#174082) when accessing Editor options. Fortunately this showstopper was already fixed in trunk at that time. Good catch Stefan!

   * Nigel Leck is back with his "hard core" performance issues. :-) He invalidated #173720 later himself but an _IDE crash after OOME_ during scanning sources (#174177) looks serious. We are investigating...

   * Claudiu Bulcu was the first one who reported another _reproducible deadlock_ in Editor (#174031). This obvious showstopper was fixed next day.

   * Claudiu must have a very sensitive sight as he spotted a _flashing popup window_ with documentation on every keystroke (#174200). We have fixed this same day.

   * Niklas Matthies gets _IllegalStateException on first start_ of M2 after import of settings from 6.7.1. The issue (#174131) has something to do with no Internet connection and his J2EE projects setup. Unfortunately we can't reproduce it ourselves... :-(

   * Michel Graciano evaluated Milestone 2 but he can't seriously use it due to _many "slowness detected" issues_ (#174218, #174143, #174152 or #160377 with already 13 duplicates). 2 blocked AWT reports were fixed and 2 others need more investigation. Some news Re: #174152 Michel?

   * Best bug reporter of the previous week was again Eric Smith with 15 submitted issues. Thanks Eric!

4. *Statistics*

   Bugs submitted: 309 (+88)
   Open bugs:      153 (2/8/126/14/3)
   E-mails:        538 (+96)

Any ideas for the next status report? Let me know!

Best regards,
-Jirka

Jiri, what do you mean by join?

Today I had to delete the cache. After new start, the scan finished
after ~4 minutes. This is much better than before, as it was ~15 minutes.
Hopefully http://www.netbeans.org/issues/show_bug.cgi?id=166668 will be
considered soon.

About this issue, I closed the issue as invalid since even me can't reproduce it after clean up my index cache. Maybe it is related or not, I am not sure but since I can't reproduce it I think it was side effect from some fix or change. BTW, the slowness blocked my work since build after 100909301401 (the last build I can use in production), after that is just impossible to work with IDE. Any change on Swing form makes IDE freeze for a while. This issue was already fixed (I hope) and I will test it asap.

Hi Ulf,

I think Jiri want all of us test it, not just you, and send ours feedback as well to try to figure out if there is more use cases where this kind of thing happens.

Right now, memory usage is hovering around 144MB with occasional peaks
into the 180's.  If the peaks hit back up to the 200MB range, I'll send
in a memory dump.  Until then, I'm still within a normal range for my
application.

Hi Ulf,

   by "joining you" I meant providing own opinion about new classpath scanning just like you did it and replied to David Strupl's e-mail on 10/9.

BTW, the improvement from ~15 to ~4 minutes looks very promising. :-) Thanks!

Best regards,
-Jirka

Thanks Michel for the update! Looking forward to your verdict.

Great, please monitor this Eric and keep us informed if the 200MB threshold is exceeded.

Thanks a lot,

BTW: What's about adding a link like
http://www.netbeans.org/servlets/ReadMsg?list=netcat&msgNo=16938 to each
mailing of the list as a footer line?
This would make it more easy to refer to an explicit posting when using
normal email client like Mozilla Thunderbird.

So, here is it. I verified it today and looks pretty good now in build 200910140201. Now this is my production build as far as it looks stable.

I don't know how to do that. And by the way, do you mean a link to the post itself?

I am afraid it's not doable.

Yes, exactly this. :-)

Here an example, how it looks on TortoiseSVN mailing list. BTW, they are too using Collabnet Software. :

Hi!

 

I think this Tree-View is a result of a Mail-Header-Tag.

Mail-Header-Tag-Name is "References" (Message-ID of the previous Mail).

If I understand correctly, the Ulf question is about the link to mailing list archive. I really agree that this is really useful and this is the first time I saw it and I miss this a lot. Great tip Ulf.
