Hi all,
The Wildfly start-up as service scripts
wildfly-init-redhat.sh and wildfly-init-debian.sh
currently depend on a grep action of key message 'WFLYSRV0025:' in console log to determinate whether
service start is successful. The log message indication is
accurate, however, it's not that robust since user can always
remove console handler from logging subsystem. I have opened a
WFCORE enhancement jira https://issues.jboss.org/browse/WFCORE-747
for it.
For the moment, I have tried three options, they're all not that
perfect to implement
1. Stay with exact log message, users need to define their jboss
log directory such as $JBOSS_HOME/standalone/log/server.log for
standalone and $JBOSS_HOME/domain/log/host-controller.log for
domain instead of searching in console log. This is more like
another workaround since it is also volatile once we
update log message in future release.(EAP has 'JBAS015874:')
2. Use service pid, this is not precise because a long start-up can
crash in the last second. It needs to wait a suitable seconds before
checking pid
existence. and still it can not avoid fake success in rare case just
before timeout.
3. Use read-attribute server-state through CLI connection as I did
in Pull Request on Jira. This is declined as it is possible that
authentication is required before connection. In such case, any non
encrypted password is not advised in configuration files.
Therefore, I would like to listen for your opinions for them. Any
other suggestion is certainly welcomed in mail or on jira.
Best regards,
Chao
