opengrok Opengrok Starting New took just 1 project

Hello Team,

I removed all the info inside data and did a reindex with the below command for opengrok 1.7.11.

nohup java -verbose -Djava.util.logging.config.file=/var/opengrok/etc/logging.properties \
    -jar /var/opengrok/dist/lib/opengrok.jar \
    -c /usr/local/bin/bin/ctags \
    -s /var/opengrok/src/margot -d /var/opengrok/data -H -S -G \
    -W /var/opengrok/etc/tomcat10/configuration.xml -U http://localhost:8080/source &

it just shows only one project from /var/opengrok/src/margot

where as I have 3 projects

/var/opengrok/src/margot
drwxr-xr-x 166 p4build users     4096 Jul 12 06:05 mainline-git
drwxr-xr-x 142 p4build users     4096 Jul 12 08:05 92xx_scale-git
drwxr-xr-x 143 p4build users     4096 Aug  1 19:28 c2c-git

in /var/opengrok/data/xref i see all 3 reference are there

92xx_scale-git  
c2c-git  
mainline-git

How I can redo the steps, Please let me know which will be a suitable command to get all projects without any issue.

Do you see all 3 mentioned in /var/opengrok/etc/tomcat10/configuration.xml ? Is there anything interesting in the logs (error, warning level entries)?

Aug 02 '21 10:08 ahornace

Archive.zip Yes I see 3 references there in the configuration files. uploading it and the logs as registered in nohup.out

Thank you

Aug 02 '21 11:08 sahoode

The uploaded logs contain only class loading details. Could you try to add the -P option and monitor the logs? Both in indexer and webapp. There should be a hint for what is happening (and what the problem is).

catalina.out.zip I get warining like:

is this fine?

this is a git repo

Log files has entry like: </record> <record> <date>2021-08-02T23:12:59.172278Z</date> <millis>1627945979172</millis> <nanos>278000</nanos> <sequence>1231674</sequence> <logger>org.opengrok.indexer.analysis</logger> <level>FINEST</level> <class>org.opengrok.indexer.analysis.Ctags</class> <method>trySplitSource</method> <thread>42695</thread> <message>Re-read /var/opengrok/src/margot/92xx_scale-git/aos-cmn/platform/os/linux-3.18/drivers/misc/genwqe/card_ddcb.h</message> </record> <record> <date>2021-08-02T23:12:59.174524Z</date> <millis>1627945979174</millis> <nanos>524000</nanos> <sequence>1231675</sequence> <logger>org.opengrok.indexer.index</logger> <level>FINER</level> <class>org.opengrok.indexer.index.DefaultIndexChangedListener</class> <method>fileAdded</method> <thread>42684</thread> <message>Added: /92xx_scale-git/aos-cmn/platform/os/linux-4.4.60/arch/sh/kernel/sh_ksyms_64.c (CAnalyzer)</message> </record> <record> <date>2021-08-02T23:12:59.174667Z</date> <millis>1627945979174</millis> <nanos>667000</nanos> <sequence>1231676</sequence> <logger>org.opengrok.indexer.index</logger> <level>FINEST</level> <class>org.opengrok.indexer.util.Statistics</class> <method>logIt</method> <thread>42684</thread> <message>file '/var/opengrok/src/margot/92xx_scale-git/aos-cmn/platform/os/linux-4.4.60/arch/sh/kernel/sh_ksyms_64.c' indexed (took 9 ms)</message> </record>

I see some errors related to repo mainline and 92xx in the catalina.out hence attaching it.

Aug 02 '21 22:08 sahoode

It seems that the other projects are not marked as indexed in the configuration. Did indexing actually finish successfully?

Can you try simply adding 1 project at a time and monitor the indexer and webapp logs?

Aug 04 '21 00:08 ahornace

Yes, the index finished successfully.

yes in configuration.xml I see the projects are not set as indexed.I will try to index individially

when I run the indexer I get the below waring is this something related

Aug 04, 2021 6:38:55 AM org.opengrok.indexer.util.Executor exec WARNING: Non-zero exit status 1 from command [p4 files $'*'] in directory /var/opengrok/src/margot/mainline-git/platform/sb_bpinfo: * - must create client 'opengrok3' to access local files.

Thank you @ahornace for the help and guidance. Now I have removed all the projects and trying to index just one I see few severe in the logs.

Now I use

nohup java -verbose -Djava.util.logging.config.file=/var/opengrok/logging.properties \

What command I should use to index one project?

Looks like ctags crashed or was killed. Neither should cause indexer to fail. Still, consider upgrading Universal ctags.

Aug 09 '21 09:08 vladak

Now I use

nohup java -verbose -Djava.util.logging.config.file=/var/opengrok/logging.properties \
    -jar /var/opengrok/dist/lib/opengrok.jar \
    -c /usr/local/bin/bin/ctags \

    -U http://localhost:8080/source &

What command I should use to index one project?

Convert this to something like (assuming the configuration file was created beforehand and the project with its repositories is already present there) this:

nohup java -verbose -Djava.util.logging.config.file=/var/opengrok/logging.properties \
    -jar /var/opengrok/dist/lib/opengrok.jar \
    -R /var/opengrok/etc/tomcat10/configuration.xml \
    -U http://localhost:8080/source \
    -H INSERT_THE_NAME_OF_THE_PROJECT_TO_INDEX_HERE \
    INSERT_THE_NAME_OF_THE_PROJECT_TO_INDEX_HERE &

Thank you for the help.

when I index the folder I get below error for the mainline-git which is not getting indexed.
