I found a cause, I'm testing a fix today. I did want to add it in the last push to avoid to many change in one version, and allow to use the fix from the today published version (mainly the remove of .class at wrong time) alone.

Seems so, yes. No freeze this morning, and I'm working in a way

I also get freezes since 1-2 weeks. Its really horrible.
But I have many plugins (maven etc.. so its maybe not the scala
plugin).

Where do I find the stacktraces so I can post them?

Build id: 20100218-1602
I have the build of today.
The computer seems not to be under load.

To get stack dumps, you have to start Eclipse from the command line
and send it a signal when you want it to dump the current stack. On
Windows, I believe you type Ctrl-Break in the Terminal. On Unix
systems, you can type "kill -3 <eclipse_pid>" in another terminal to
send the signal.

HTH,
J.-P.

Hi,

an other option to have a dump

* start jvisualvm (part of jdk 1.6 since update 20 IIRC)

* connect to your running eclipse (right click + open)

* create a Thread dump (right click + thread dump)

* then save or copy/paste

Which version/branch of scalaIDE dod you use ?

Hi Ido, I think you can also use jstack.

Usage:
jstack [-l] <pid>
(to connect to running process)
jstack -F [-m] [-l] <pid>
(to connect to a hung process)
jstack [-m] [-l] <executable> <core>
(to connect to a core file)
jstack [-m] [-l] [server_id@]<remote server IP or hostname>
(to connect to a remote debug server)

Options:
-F to force a thread dump. Use when jstack <pid> does not respond
(process is hung)
-m to print both java and native frames (mixed mode)
-l long listing. Prints additional information about locks
-h or -help to print this help message

if you use 'jstack', you can use 'jps' to have the list of pid of java process

Ido, from the stack trace, if I understand right you use "master". Some lock/freeze of this version was removed in wip_exp_backport, but can't be applied as is into master (for various raison).

Can you give a try to the following version of ScalaIDE (should work for Galileo 3.5.x and Helios 3.6.x) :

Here's another stack trace from a freeze with today's nightly build.
How come there are so many worker threads?

Here's another stack trace from a freeze with today's nightly build.
How come there are so many worker threads?

If not set, I suggest you to check (enable) preferences "mark occurences on selection".

Today, I changed the findOcurrences method to not spawn a Worker Thread every time (several possible strategies to test).

Is it recommended to be on the wip? I feel like I've seen the same bugs forever in the master. Is all work going into wip now? If not yet recommended, is the goal that wip will eventually become the master? If so, do we have an ETA?

IMHO, Yes If you're ok to revert an update of the plugin (mainly by using a previous version, from CI archives or from your local eclipse history)

But advice of other users are welcome (opinion of the maintenair ( me ) is not the reference ;-) )

I feel like I've seen the same bugs forever in the master. Is all work going into wip now?

All work in mainly done on wip_exp_backport => less stable (in behavior) than master.

I'll have less time next month to work on wip_exp_backport => less activity

If not yet recommended, is the goal that wip will eventually become the master? If so, do we have an ETA?

wip could become master when :

* current master/helios will be freezed and published as version 1.0.0 (only Miles Sabin can do it)

* other committers will agree, to make wip_exp_experiment the master and move version to 1.1.0

ETA ? (I'm ok for now, may be it's time to do a vote)

Can you give a try to the following version of ScalaIDE (should work for Galileo 3.5.x and Helios 3.6.x) :

Hi,

I'm using the wip_exp_backport for some time now and its far better
that master, in my opinion. No constant freezes, less bugs. BUT, there
are lots of changes to wip_exp_backport and for about two weeks its
not really working for me anymore. Therefore I'm currently still using
the nightly of 2011-01-06.

Of course, there are problems, too, but in general its much more
usable than master.

In the long run, I expect the branch of the Scala team
(wip_experiement) will be the new master, but that's just my
impression.

Regards,
Ruediger

I push some change in wip_exp_backport, and one of them allow you to configure the threading strategy to run "mark occurences" :

* in shared actor (default)

* not in main thread (when main thread is lock or run long computation GUI freeze)

* in a dedicated worker (can generated lot worker thread if there is lock, it was the strategy of last week wip_exp_backport, I also fix a bug in occurences marker that can generate lot of useless job and worker)

* in the caller thread (synchronous call regardless if it's in main Thread or workers,... the java editor and master branch strategy)

If you don't care about mark occurences, you can diseable it from Preferences > Java > Editor > Mark Occurrences

This should remove some freeze or at least allow user to tune its ide.

Here's another stack dump with the latest version. It doesn't look
like it has anything to do with marking occurrences.

Let me know if posting those dumps helps; if it doesn't, I'll just
keep them to myself.

Cheers,

dumps, help me to understand the beast. But if you can attach them instead of copy/paste (gmail wrap text in Plain Text mode)

jstack -l $eclipse_pid > dump.txt

I'll study your last dump later.
