Scala IDE Hang - thread dump

[Alex Black]

Now and then the Scala IDE (or Eclipse) appears to hang. No CPU is
being used by java processes (or any other), Eclipse goes grayed out
(Ubuntu).

This time, I ran jstack on the offending pid, and got this report,
does this help towards fixing the bug at all?

There appear to be two threads waiting on lock(s), but jstack doesn't
actually report a deadlock.

This just happened again, I've lost work/changes.. (I don't hit save
all the time because that causes the IDE to complete rebuild and takes
several minutes)..

Any ideas how I can fix/workaround/prevent this? Or is there more info
I can contribute?

No idea,

I save frequently, and save doesn't trigger full rebuild (build
Automatically enabled).
I'll try to allocate time next week to work on it.

[Alex Black]

Incremental build does work for me in a single project, but I have two
projects open, and if I change the 'lower' one then the upper one gets
completely rebuilt (http://groups.google.com/group/scala-ide-user/
browse_thread/thread/2380e69d2749c840)

I usually have auto-build on, but if I am making many changes in a
lower project I will turn it off, make all my changes, manually build
the lower project, then turn auto back on.

Fwiw, I'm seeing the same symptoms (2 same threads blocked) on OS X,
Eclipse Helios and nightly build 2.8.1 updated yesterday.

/Jeppe

[David Chase]

Eclipse 3.6.1, freshly unpacked, plus Scala 2.8.0 IDE plugin from earlier today.
Hang occurs right around startup.

On a whim, I decided to see if I could get information out of jconsole,
and on another whim I decided to click the "deadlock" button, and lo,
deadlock. With details. I hope you can use this.

Thanks for reporting. We're working on an "improved" version that should avoid this issue.

PS/note -- this was also reproducible in Galileo with the 2.8.0 plugin, and the repeatable deadlock cleared when I blew away the scala-related cached metadata ("rm -rf .scala_dependencies .manager" did the trick, I do not know which contained the deadly data).

I checked the status of the ticket, it still says new. Is there any
way I can encourage someone to look into fixing this? The IDE locks
up a few times a week for me, twice this evening. Every time it locks
up I lose whatever I haven't saved, and then when I re-open Eclipse I
have to wait while it rebuilds or something. :(

Do you have the same issue with wip_exp_backport ?

(I did some change in this version for similar issue)

/davidB

[Alex Black]

I haven't tried anything except the final releases. I'll give it a
shot, I guess I'll have to run it for a week or so and see if it
happens.

[Alex Black]

I just experienced a lockup in the IDE, but I think its a different
issue, this time the Java process is using 100% cpu (of one core
presumably) for the last few minutes. Ubuntu greyed out the ide. I
was in the middle of typing.

Alex,

some of the lock seems to be trigger by "content assist". If you doesn't need auto-display of content assist (javadoc, completion,...).

I highly suggest you to disable it (see https://www.assembla.com/wiki/show/scala-ide/Setup)

Thanks for persist, and to for your future try of wip_exp_backport.

Where do I get this? (wip_exp_backport, I'm using 3.6/2.8.0) I just got nailed by another deadlock, not interested right now on blowing away metadata and starting a rebuild from scratch.

[David Bernard]

wip_exp_backport is an **experimental branch*** (and unstable) for Galileo / scala 2.8.1 (version for scala-2.8.0 is not deployed)

update-site: http://download.scala-ide.org/nightly-update-wip-exp-backport-2.8.1.final

Cheers,
