Cannot open folder in OpenGrok

[YongJ7]

Describe the bug
I cannot open folder in OpenGrok,,

installed tomcat 10 & java 17(openjdk-1.17.0) & opengrok 1.12.20
http://localhost:12333 connection is OK
also http://localhost:12333/source connection is OK
But when I click dlt-daemon on opengrok,, below screenshot appears..

Below is the command I used to do indexing

java -Djava.util.logging.config.file=/var/opengrok/etc/logging.properties -jar /var/opengrok/dist/lib/opengrok.jar -c /usr/local/bin/ctags -s /var/opengrok/src -d /var/opengrok/data -H -P -S -G -W /var/opengrok/etc/configuration.xml -U http://localhost:12333/source

And I attached the log file for indexing.

opengrok0.0.log

Please help,,

What was the URL you accessed ? Is there anything relevant in the Tomcat logs ?

[YongJ7]

@vladak,
http://10.157.110.123:12333/source/ this is my URL for opengrok
I have attached the log file. And when I used my command in terminal to do indexing below appeared.
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I meant: what URL did you access that caused the error ?

[vladak]

The log file you attached is from the indexer. That looks okay. The key is what is in Tomcat logs.

@vladak,
I don't understand " what URL did I access",,
And for tomcat log,, It seems these two cause the problem
org.opengrok.indexer.util.ForbiddenSymlinkException
java.io.IOException: Could not create suggester directory

[vladak]

When the error was displayed, the URL field of the browser had a value - what was that value ? was it http://10.157.110.123:12333/source/ or something else ?

Also, the Tomcat log fragment is not very helpful, I need to see more to be able to tell what is going on.

@vladak ,
http://10.157.110.123:12333/source/xref/dlt_daemon this is the URL when error show.

And below is the log file from /opt/tomcat/logs/catalina.out

This might be related, although the error message is from repository invalidation, which happens when the webapp is deployed, not when a request is being processed.

Is /var/opengrok/src/dlt-daemon indeed a symlink ?

Anyhow, it is strange that such symlink was refused, given that by default all symlinks directly under source root should be allowed.

[vladak]

When the indexer is run on a source root that contains symlinks, such symlinks are stored in the configuration file specified with the -W indexer option, like so:

<?xml version="1.0" encoding="UTF-8"?>
<java version="11.0.20.1" class="java.beans.XMLDecoder">
 <object class="org.opengrok.indexer.configuration.Configuration" id="Configuration0">
  <void property="allowedSymlinks">
   <void method="add">
    <string>/var/opengrok/src.symlinks/openssl</string>
   </void>
  </void>
  <void property="dataRoot">
   <string>/var/opengrok/data.symlinks</string>
...

When the webapp starts, it will read this configuration and the list of allowed symlinks will become part of the runtime configuration. What is in your /var/opengrok/etc/configuration.xml ?

@vladak ,
No matter what I did, it didn't work, so I reinstalled Ubuntu 18.04 and tried again, and it worked normally.
Let's close this issue. Anyway, thank you for your help
