Description Michel Graciano 2010-03-08 13:29:27 UTC
Code completion time after time show message 'Scanning in progress' but just CVS process are in progress and I need to restart the IDE to get it working again. I can't reproduce it with defined steps but I face it 2 or 3 times per day. I will attach thread dumps always it happens.

New thread dump

Well, the steps I use to reproduce it:
1.Starts an project CVS update;
2.Wait few seconds when the CVS operation starts and try to call CC or even Find Usages tools, and the message 'Scanning in progress...' is shown;

In process list I just can see the update action, the 'Scanning project' is just shown when the update finish. This new thread dump I started before starts CVS update action and stopped just after try to call CC.

One more sample

I take this report with daily build.
Comment 4 Michel Graciano 2010-04-20 18:29:57 UTC
The same behaviour could be seen for Find Usages and another IDE features too.

One more sample

This is a sample I've taken from 6.9.1 201007131557.
Comment 6 Michel Graciano 2010-07-27 14:17:08 UTC
I increased the priority because it just avoid me to keep working when I am doing a huge checkout which take hours.
Comment 7 Tomas Zezula 2010-10-25 15:47:46 UTC
From the nps file there is no scan running just the VCS update. But the VCS operation blocks the code completion.
Comment 8 Tomas Zezula 2010-11-02 14:24:18 UTC
Fixed jet-main 8e4091d6d215
Comment 9 Michel Graciano 2010-11-03 11:19:53 UTC
It is still valid. I will attach a new snapshot soon.

Thread dump updated

Another side effect I can see is that the code is not formatted too in this cases. For formatted, in this case I mean the code is not folded and some paintings are not performed. I will attach another picture about it soon.

Picture about formatting/highlight issues

I am not sure if this issue against formatting/highlight is related to this, so please evaluate and if possible I can file a new issue just about it, but I think all these things are related with the case that the IDE "thinks" the scanning is in progress.
Comment 12 Tomas Zezula 2010-11-03 12:58:20 UTC
According to your snapshot the IDE does real scan, so the code completion has to wait on it.
The VCS operation does not hold the scan lock.
If you have a snapshot where there is no scan active and code completion waits on scan please reopen this issue.
Comment 13 Michel Graciano 2010-11-03 13:16:05 UTC
First thing, if you can't reproduce this last comment, I think you should mark it as fixed as before instead worksforme.

About this issue, if you look at my last picture, you can see that just CVS update is running and it was still performing and no scanning is running (see that '1 more' is not present, so just 1 process is running). I am aware that when a cvs update operation finishes it runs the scanning but in this case it was still downloading a lot of jars. Could explain to me why the scanning is running, according to thread dump, and I can't see it in the process bar?
I have no idea what is starting the hidden scanning, but it looks like be always related with my CVS operations, usually update. Do you have any idea what kind of test could I do?

Comment 14 Tomas Zezula 2010-11-03 13:25:17 UTC
OK, resolved fixed.
You can look into the attached nps file. You will find RepositoryUpdater$Task active. The scan is active and the CC cannot be started until it leaves the critical section.
I will add a logging which you can enable and let you know. You will need a newer build, I will add the logging later today. Now I have uncompleted changes in my repository.
Maybe the CVS operation does twice the protectedMode operation which starts the scan, we will se from the log.

Comment 17 Michel Graciano 2010-11-03 18:13:37 UTC
Thank you Tomas. I will test it soon :)
Comment 18 Tomas Zezula 2010-11-03 18:21:25 UTC
I've added logging and also attached a screenshot how the update looks like.
To use the logging you need to start the netbeans with the following option:

It will generate tons of logging. To find something you will need to prepare the set up to minimize the output. Open the file you will try the code completion on it. Select the project to update. Do several empty lines in the console to find out from where the logging is important. Start the update. Again do several empty lines in console and invoke the cc.
Then attach the output from the first empty spaces to the end.
Thanks. It's really important to limit the logging as the logging is very intensive.
Comment 19 Tomas Zezula 2010-11-03 18:22:19 UTC
You will need to wait until it propagates from jet-main into main-silver. This can take several hours.
Comment 20 Michel Graciano 2010-11-08 13:19:52 UTC
I can't reproduce the problem today. I will keep looking for any kind of problem and I can report it later. Thanks for the help.
