CSIDE/Eclipse freezes every time I make an object change

There was an error rendering this rich post.

Hi,

I'm noticing with the latest CSIDE plug-in on CS 20.4 that any time I edit an .os file and try to save it, Eclipse freezes up for about 45 seconds to a minute. During this time, the application is showing in task manager as non-responsive. I have the same plug-in on CS 20.2 and CS 20.3 without this issue (or at least I haven't noticed it yet).

Obviously this can make development extremely slow.

I'm using Eclipse 2020-09 (4.17.0) and the installer gave me a JDK hotspot plugin (or so it seems), I'm going to attempt to get a more recent Eclipse and a separate JRE installed first.

I checked the release notes and it didn't make any mention of which JDK/JRE I should have installed, so theoretically I have a supported environment. I also tried different JDKs with my eclipse. I tried both hotspot and J9 from AdoptOpenJDK and I now have the reference JDK 11 from Oracle for OpenSDK. The last one gave marginally better performance. I am basically using the latest Eclipse edition (Java SE, not EE).

Has anyone else observed this behaviour?

Hi Hugh - sorry you're having issues. We support any JDK that eclipse does, and the version of eclipse you're using is fine (FWIW we raised the minimum recently).

Two quick questions:

A) can you provide details on the type of eclipse you're using / what other plugins might be enabled? If you aren't using a vanilla-ish eclipse (such as the one for Java developers) would it be possible to give that a shot? I know you mentioned Java SE above, but any details on the specific link used (and also what other plugins show up on the 'about' screen) appreciated :-)

B) would you happen to have build automatically enabled? Nothing illegal about that if you do; just asking since if that is enabled then it's possible the time needed is coming from the ensuing build activity.

... if neither of these could be an explanation / change the outcome: feel free to grab the goodies outlined @ https://knowledge.opentext.com/go/KB12497600 & open a support ticket.

Hi Dave

I'm facing the same troubles Hugh does.

Are there any solutions available?

Here are an additional details:

A) Eclipse IDE for Enterprise Java Developers (includes Incubating components) Version: 2020-12 (4.18.0) Build id: 20201210-1552

B) Yes, build automatically enabled

Hi Alexandr - sorry you're having this issue as well. I do not know if either of these will resolve, however since you have an environment where this is reproducible: could you try the following:

Use "Eclipse IDE for Java Developers" ( https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/2020-12/R/eclipse-java-2020-12-R-win32-x86_64.zip )
Disable 'build automatically'

... the first suggestion has resolved odd hangs seen internally on occasion, however there's no guarantee either of these will fix things for you. But I think it's worth a shot. If these do not resolve (or the first one is not an option) : as mentioned: grab the logs requested via the link mentioned earlier & open a support ticket so that investigation over here can commence :-)

I am currently doing a little bit of Oscript work and I use this

and I think I am using this plugin com.opentext.cside_20.2.0.v20200220_01596.zip seems fairly stable although eclipse seems not to be able to get all windows resources like Oscript changes etc unless I deliberately invoke the command "Run as Administrator".FYI I am a domain user added to the Administrators group in this Azure VM.It does crash from time to time but for the most part very stable than many predecessors. My CS is 16.2.8. and I am on auto build.

Never be afraid to open a ticket :-)

I'm very glad to hear that - usually I'm only involved when things go wrong, so the change of feedback is appreciated :-)

It would be nice to open a ticket. Since most customers don't allow Oscript development, and partners need to be through a customer to open tickets, this isn't an option for most of us here.

I always use the Java IDE when I have the chance, and always get the latest plugin. Having said that, I haven't got the latest 21.x plug-in but the one before that, which is where I started noticing this behaviour. It's not a very good option to disable build automatically. It does slow down our development quite a bit. And given that it's only in the last couple of iterations of the plug-in that this seems to be an issue, I have a hard time believing it's my code base to blame.

This I did not know - apologies for my ignorance. I've emailed you directly to see if providing logs is an option - if there is a bug at play here I'd (obviously) like to see it squashed.

It's not a very good option to disable build automatically

Apologies for not being clearer in the suggestion: I wasn't seeing this as a fix - I was just curious if the problem went away if that was in place (if so: something is funky with building).

I have a hard time believing it's my code base to blame.

Me too :-)

We are experiencing the same issue with eclipse 2020-12 / cside 21.1 / Content Server 20.4 / java 11.0.7, but this is something which has been happening for a while with previous versions as well.

In my experience, the problem takes some time to show up - typically a few hours. Restarting eclipse does not fix the issue, but things go back to normal if I reboot the machine.

If I capture the machine's activity while eclipse gets stuck, it looks like this (25 seconds during which there is a lot of network events registered):

in details, I have ~ half a million events that look like the below over 25s (the machine's hostname is what is blurred) :

For the above, I have just added a space to a file and saved it.

Dear Dave, thank you for your advices. I'm really appreciate attention from plugin dev team/

Tried to use java se eclipse instead of java ee, but it didn't worked for me. Changing plugin version down to 20.3 neither helped.

It's still keep freezes and already made me mad. May be opentext should consider to open plugin sources and make it an open source solution?

I'm quite sure, community would be able to fix it and even develop.

Dave Carpeneto

@Stephane Genoux : I think I might know what the issue is.

Some questions for you (as well as @Alexandr Arzamastsev & @Hugh Ferguson ) :

A) Is it possible that the issue manifests after expanding a bunch of stuff in the module explorer view?

B) If so: is it possible that collapsing all the expanded objects in the module explorer, then restarting the server (or eclipse) resolves (until such time that a bunch of items in the module explorer are expanded again)?

... if so: 21.2 will fix this (hopefully out by mark / under QA now). It appears that this is a change in eclipse behavior in recent versions which caught CSIDE doing silly / sub-optimal things. Since newer CSIDE releases require newer eclipse versions this has become an issue for a few internal people as well.

If this isn't the case: I'd love to see logs of any type (lemme know if that's an option & I'll shoot you an email / create a transfer site to facilitate collection).

Note that the collapsing of the objects then restarting stuff is the current work-around - both steps are needed (assuming we are talking about the same thing).

Thx, Dave

Stephane Genoux

@Dave Carpeneto : It look like this is indeed the issue.

I had an instance of eclipse with this issue: the delay is gone after collapsing everything (Oscript Explorer + Module Explorer) and restarting eclipse.

After that, I have spent 1 inute opening ospaces / expanding items and the "freeze for x seconds on save" was back

Dave Carpeneto

OK, so once 21.2 is out you should be good. Till then I guess we know what's going on / how to mitigate, though it's not fun to live that way. Another suggestion for the time being: disable auto-build, since you're gonna see this every time you save a file if you don't do that.

FWIW 21.2 is targeting the end of March / beginning of April. However that's a guess / don't yell at me if this is not the case / I don't own timelines.

Thx, Dave

Alexandr Arzamastsev

Dear Dave, are there any updates on topic?

I've been using the 21.2 plugin now for about a week. It still has a little delay when rebuilding but a 5-10 second delay (and sometimes even just 1-2 seconds) is a big improvement over the 30-90 second delay I was getting.
