            Bug ID: 57507
           Summary: Deploying new Context fails if the context file is
                    already present in the catalina directory
           Product: Tomcat 7
           Version: 7.0.55
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: joekislos@gmail.com

Deploying new Context fails if the context file is already present in the
catalina directory

This worked in 7.0.52, and does not work in 7.0.55 and 7.0.57.  I did not test
the intervening verions to figure out which release introduced the issue.

Here's how to reproduce:

1) Start tomcat

2) Place a new context file into the catalina context directory here:
/var/lib/tomcat/conf/Catalina/localhost/test.xml

3) Tell tomcat there's a new context:
Goto URL:
http://webserver/tomcat-manager-app/deploy?path=/test&config=file:///var/lib/tomcat/conf/Catalina/localhost/test.xml"

4) Deploy fails with this message:
FAIL - Failed to deploy application at context path /test

Previously it would deploy fine.

It appears that deploying does not work if the source of your context file is
it's final destination.  I traced a chunk of the code, and this is being caught
by a generic "something bad happened during the deploy"... I didn't see any
useful debug messages or why it's failing.  After it fails, it deletes the
test.xml file.

A work around would be to create a secure temporary directory to write the
context files to and give that path to catalina.

Unfortunately that workaround isn't terribly exciting for us for a few reasons:

1) We need to be able to deploy context's when tomcat is not running, and we do
that by writing the context file in directly

2) Creating a single purpose secure temporary directory with the correct
permissions, owner and group would be cumbersome to create and manage

3) After tomcat copies the context file, we would need to manage the ownership
and permissions of the context files.

Hi,

Can you post here also the configuration for the Host.

You can find it in server.xml Host element.

Thanks,
Violeta
