Data source xml change not taking effect in first karaf start post
modification
I have an application that uses a postgresql database. I am using PGSimpleDataSource configured using a data source xml placed in $KARAF_HOME/deploy directory. Noticed an issue when the database xml file is modified.
When I shutdown karaf, modify the data source XML to point to a different database and start karaf, it is still taking the old database connection parameters. If I restart again it connecting to the database that is configured in XML file. Is Karaf caching connection parameters ?
regards
Vinu

The fact to have felix.fileinstall.file property and use it is in ConfigAdmin. But the monitoring of the etc folder is in Karaf. If you take a look in etc/config.properties, you will see:
#
# Configuration FileMonitor properties
#
felix.fileinstall.enableConfigSave = true
felix.fileinstall.dir = ${karaf.base}/etc
felix.fileinstall.filter = .*\\.cfg
felix.fileinstall.poll = 1000
felix.fileinstall.noInitialDelay = true
felix.fileinstall.log.level = 3
That's the monitoring/polling on the etc folder.
More over, the creation of the cfg file when you use ConfigAdmin
(config:* commands for instance) without felix.fileinstall.dir is
directly in Karaf.

Hi JB,
I always thought that this was already built into config admin.
is the code that takes car of this part of the karaf config module?

Hi Christian,
actually, ConfigAdmin itself doesn't directly use FileInstall: the
monitoring of the etc folder is a Karaf feature, no a ConfigAdmin feature.

config admin doesn't use fielinstall, fileinstall uses config admin to
update configurations.
BUT, it is rather strange that the default configuration handler does
behave differently then the one for blueprint.xml files.
So it has to be something in the canHandle method of this deployer. Cause
if this one says No, the file will never be looked at again till the next
restart
which is the case here.

That is an interesting observation. Config admin and the deploy folder
both use fileinstall to monitor the directory. Still config admin seems
to notice changes that occur while karaf is offline.
So perhaps we are just not using some fileinstall feature config admin uses.

While this is not going to be a high impact issue in my environment, in my opinion this is an issue for two reasons
1. Karaf is starting up with an obsolete configuration . I can understand Karaf not able to pick up change in file while it is down. But when it starts, it should be able to pick up the change in configuration rather than using a configuration that is no more valid.
2. When I use property place holders with database credentials in a properties file, this issue doesn’t seem to occur. So the behavior no consistent.

No I don't think it is really an issue, as the FileInstaller monitors the files it already installed.
But if you change it while Karaf is down it usually isn't capable of doing so.
Another way would be to install the xml file via maven.

No I don't think it is really an issue, as the FileInstaller monitors the
files it already installed.
But if you change it while Karaf is down it usually isn't capable of doing

Database parameters are directly mentioned in the blueprint. If I cleanup data folder and start Karaf, latest configuration is considered. Like Achim mentioned, the issue happens when the XML is modified while Karaf is down. Isn’t that a problem ?
When I store the database credentials in a properties file and use Apache Aries blueprint extension for property placeholder to import and use the values, the issue doesn’t seem to occur. Noticed this when I was trying to enable database credentials encryption using Aries blueprint extension and Jasypt as mentioned in fusesource security guide.

I think the main problem seems to be, the xml file was altered while karaf wasn't able to realize it's been altered.
After the startup it still used the old one as there has already been a bundle generated for it.
My best guess right now, this is due to the fact that karaf/FileInstaller wasn't "seeing" the change it wasn't able to "re-load" the change,
make sure you alter it while Karaf is running then it will be able to get it faster.

This is an issue. We have users who will not know this unless it is
explicitly documented.
You should be able to modify the datasource-xxx.xml file when karaf is not
running and karaf should always check for any changes to the xml files in
deploy dir vs. the already deployed xml bundles. Then this wouldn't be a
problem. So a bug/enhancement request is in order I believe...

No Issue, just not the right usage?
If Karaf is running, the change is detected.
It is even detected when the Karaf Instance is shut down.
So it works as designed, AFAIC.

I also think this is the issue.
Do you think this should be filed as a bug in felix fileinstall?

I agree, and it's what I said by purging the data folder.

I think the main problem seems to be, the xml file was altered while karaf
wasn't able to realize it's been altered.
After the startup it still used the old one as there has already been a
bundle generated for it.
My best guess right now, this is due to the fact that karaf/FileInstaller
wasn't "seeing" the change it wasn't able to "re-load" the change,
make sure you alter it while Karaf is running then it will be able to get
it faster.

It depends of the blueprint: if the parameters are directly in the
blueprint (not in cm), ConfigAdmin is not used at all.

I think the issue is that config admin stores the configuration internally
(that would be where karaf caches the connection parameters) and that the
datasource is created before the xml file is processed again.
