DO NOT REPLY [Bug 48421] New: JULI webapp logging files will not
closed when webapp is stopped,reloaded or undeployed
https://issues.apache.org/bugzilla/show_bug.cgi?id=48421
Summary: JULI webapp logging files will not closed when webapp
is stopped,reloaded or undeployed
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: minor
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: charly41434@yahoo.de
In Tomcat 6 the JULI logging files which are (can be) declared in
webapp/WEB-INF/classes/logging.properties will not closed, when the
webapp is reloaded, stopped or even undeployed. The files will at last be
closed, when tomcat is shut down or restarted.
This is also true for the normally used Handler org.apache.juli.FileHandler,
which opens a new File every day and closes the old.
On windows this has following effects:
A) If the webapp is undeployed the files which are open at this moment are
locked and cannot be deleted until tomcat is (someday) stopped or restarted.
B) If the webapp is reloaded the file is opened a second time. So the file has
two open handles.
The next day the FileHandler closes one handle but the file is kept locked
through the other handle and cannot be deleted.
Every time a webapp is reloaded the associated logfile is opened again (but not
closed).
This has the consequence that after reloading webapps a few times tomcat must
be restarted from time to time.
When tomcat is shutdown the unnecessary (and other) open files are closed and
will get the shutdown time as modification time.
That means any old log files will receive a current modification time, which is
irritating.
Steps to verify on windows: (for example: undeploy)
1. create in the examples webapp: of tomcat 6.0.20:
examples/WEB-INF/classes/logging.properties:
handlers = org.apache.juli.FileHandler
org.apache.juli.FileHandler.level = FINE
org.apache.juli.FileHandler.directory = ${catalina.base}/logs
org.apache.juli.FileHandler.prefix = servlet-examples.
2. start tomcat
3. undeploy examples using manager
Actual Results:
file ${catalina.base}/logs/servlet-examples.<date>.log cannot be deleted (nor
at the next day)
Expected:
file ${catalina.base}/logs/servlet-examples.<date>.log can be deleted
very cumbersome Workaround (working for reload):
The getHead method of a custom Formatter is extended to track the handlers
along with the classloader and webapp.
If for a webapp a different (i.e. new) classloader is detected the close method
of the handlers assigned to the old classloader is called. So the assigned file
is proper closed (and the Formatter.getTail result is appended)
I have set severity at minor because tomcat can be used (without webapp
logging). But it is a bug because with this logging the same logfile can be
useless multiple open (as described above), which should be considered as
buggy.
