Hello,
I've been running xwiki with
"log4j.logger.com.xpn.xwiki.plugin.lucene=debug" now for some days. The
problem has occurred several times but I've nothing in my logs. Is there
something else I could do/debug?
As i said i doubt "log4j.logger.com.xpn.xwiki.plugin.lucene=debug"
bring anything since Lucene plugin does not print any debug log (or
almost nothing and not useful here).
Only part of the code i see where it's possible to have the variable
null (which makes it produce a nullpointerexception) are supposed to
be covered by an error log at some point (not when you look at the
page but before). I can't see how you could have this issue if nothing
goes wrong and is then logged.
Not that this issue as finally been fixed !

I wish there was more info in my logs...I paused actively watching and
debugging this one few weeks ago because of the workaround (reinitializing
the plugin when needed in a groovy try{...getQueueSize()...} catch -block on
a search page). As far as I can remember there wasn't any lucene-errors in
my logs at the time and the search clearly returned 0 hits according to
logs. To be sure I'll put the debugging options on again and let you know
the results as soon as the problem occurs again. Are these enough?:
log4j.logger.com.xpn.xwiki.plugin.lucene.IndexData=debug
log4j.logger.com.xpn.xwiki.plugin.lucene.DocumentData=debug
log4j.logger.com.xpn.xwiki.plugin.lucene.IndexUpdater=debug
log4j.logger.com.xpn.xwiki.plugin.lucene.IndexRebuilder=debug
log4j.logger.com.xpn.xwiki.plugin.lucene.LucenePlugin=debug
log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResults=debug
log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResult=debug
You can use
log4j.logger.com.xpn.xwiki.plugin.lucene=debug
I think but AFAIK there is almost no debug log in Lucene plugin.
...
I haven't examined the code thoroughly so probably a missed shot but is
there any chance that this could be a method synchronization issue with
searchers and writers?

Everything I could find was this one problem in closing the writer:
23:00:06,242 [Lucene index updating thread] [Lucene Index Updater] WARN
 lucene.IndexUpdater             - Failed to close writer.
I forgot to mention another symptom suggesting index reading problems:
when the situation is on I can do Lucene-queries (custom search page wo
getQueueSize()) but it just doesn't return anything. So the plugin kind of
"works" but "seems" not to be able to read indexes properly.
As far as i can see in the code all search* methods in the public api
are "protected" from any Exception and return null when something
wrong happen. But it also log the error so when you do a failing
search you should have something in the log.

For your informations: as far as i can see in the code there is only
one way to have the IndexUpdater to null (whichgenerate a
nullpointerexcetion in #getQueueSize) is when during the init the
index can't be opened. In this case you should find a log looking like
this:
"Failed to open the index directory: " followed with a message
detailing a little why it can't open index directory.
(so indeed it could be caused by the fact that no more inode can be
used on linux for example).
Could you look if you can find this error anywhere in the log ?

Hello,
My issues seem to happen randomly but not at startup. Plugin works
well from some hours to some days but I'm not sure what triggers this. I
haven't been able to debug anything of interest in plugin's logs.
Only potential clue I have is that plugin is leaving index files open
which -at least- leads Tomcat finally to "too many files open" -error at
some point. lsof | grep "lucene" gives me a bunch of these:
...
java.bin  10095     tomcat  666r      REG      104,1  60931511
15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted)
java.bin  10095     tomcat  667r      REG      104,1  60931507
15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted)
java.bin  10095     tomcat  668r      REG      104,1  60931507
15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted)
...
...
Also, xwiki gets the plugin object normally during the malfunctional
state but it seems it just cannot read index. Could it be that the plugin
becomes unusable not before a deleted index file becomes overwritten by the
system? That could be the reason why the time it works varies so much
(depending on the other file system usage of the underlying operating
system)? WDT?
This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't
see how it could be the source of the nullpointer exception issue.

Hi guys,
getting some informations since i can't find just at looking at the
code how this would append.
When you have the issue, does it appending since the time you started
XWiki or does it works and at some point it stops to work even if you
did not restarted XWiki. Basically is it always a startup issue ?
And in that case do you have anything in the beginning of the log
like
a warning or something indicating that something wrong append during
lucene plugin initialization ?
