Yahor Radtsevich commented on JBIDE-10016:
------------------------------------------
*Note:* I did not review [^JBIDE-10016_20111025.patch] completely yet, but the following
change seems to be redundant, since there is only one thread, and synchronization is not
necessary:
{code:title=VpeController.java}
/**
* @return the changeEvents
*/
public List<VpeEventBean> getChangeEvents() {
if (changeEvents == null) {
- changeEvents = new LinkedList<VpeEventBean>();
+ changeEvents = Collections.synchronizedList(new LinkedList<VpeEventBean>());
}
return changeEvents;
}
{code}

----------------------------------------------
if all is thread safe here, why you got https://issues.jboss.org/browse/JBIDE-9997? how
would you fix this issue?
why you strugle for pure LinkedList? will you enhance pefrormance?
the last argument -
public List<VpeEventBean> getChangeEvents()
do you guranty what this list can't be modified from some other thread?

Vitali, thank you for the patch. But after reviewing it I can say it is not really related

----------------------------------------------
there is no sense to discuss the reason, cause here is better to provide a concrete
arguments, may be you are right with patch characteristics like JBIDE-1900 improvements. I
have only 1 arguments - with my patch - I can not reproduce exception any more. The patch
improves performance significantly. But for very complex cases the patch
JBIDE-10016_20111025.patch not a best solution... I have several ideas how to enhance it.

JBIDE-10016_20111125.patch - practically optimal with performance point of view, during
editing very-very complex custom templates for vpe and makes re-rendering very smooth and
prevent from intensive update exceptions.

Denis Golovin commented on JBIDE-10016:
---------------------------------------
mixing refactoring (two classes moved out) with bug fixing makes it really difficult to
review, so if you really want to make it into trunk you have to ether avoid refactoring
or provide two incremental patches, one with refactoring and second with fix.
I have reviewed first patch and found it good to be applied, because it seems to fix issue
with interruption of UI job and makes update faster.
Didn't have time to review the second, but I see it has "optimization",
which is counting the events and just switch to full refresh if more than 30 events
happened. I'll review it later today or Monday.
I need a JUnit test to test "optimization" in your last fix and that last thing
we need to get it applied into trunk.

Vitali Yemialyanchyk commented on JBIDE-10016:
----------------------------------------------
the difference between patches is ->
one more additional thing in second patch:
gist: I check -> is document node in the update list (in this case VPE does whole
refresh), if so - whole refresh occurred and
it is possible to cleanup the list of jobs, cause after whole refresh, there is no sense
to do other updates.
This "optimization" with limit to list of events is obligatory thing, cause it
prevents the list from growth to abnormal size.
It was the idea "how to reproduce" the issue of step 2 - overload the list of
events.
It was rather difficult for WebContent/pages/inputname.xhtml, but for rather big page with
some complex template, it could be more easy - as I think.

Vitali Yemialyanchyk commented on JBIDE-10016:
----------------------------------------------
I've choose constant size to 30 - cause it seems what the list of 30 events look like
too big,
i.e. this constant is arbitrary selected parameter, may be there is a sense to make it
less, 20 - for example.
In real life editing the user will not try to overload list of events like I did in clause
(2),
but it can occured occasionally for rather big pages and complex templates.

---------------------------------------------
Talked with Denis - this looks like a really great patch from user perspective. Hope we
can get it in for M5 after VPE review.

Denis Golovin commented on JBIDE-10016:
---------------------------------------
After chat with Yahor, we found that last patch has a potential problem loosing events. So
I applied first patch, but second one needs some work beforr it can be applied:
1. event should be removed from line after it was processed to be sure it is picked up
again if current update job was cancelled
2. full rebuild should be ether stays uninterrupted by new events or should clear all
events from line except one requires full rebuild to avoid loosing events

I've applied modified patch to avoid loosing events that must be processed. I excluded
only optimization related to update of document node.
