Subject [Bug 54596] New: Relative paths truncates last character of values
Date Fri, 22 Feb 2013 06:14:37 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=54596

            Bug ID: 54596
           Summary: Relative paths truncates last character of values
           Product: Tomcat Connectors
           Version: 1.2.37
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: isapi
          Assignee: dev@tomcat.apache.org
          Reporter: bradc@rmt.com.au
    Classification: Unclassified

Hi Team,

Found the below issue on the following environment:
  Windows Server 2008 R2 Datacentee (64 bit)
  IIS 7.5 & Tomee 1.5.1
  isapi_redirect.dll 1.2.37 (64 bit)

Issue:  Utilising relative paths in properties file for the various
configuration files (log, workers.properties, uriworkermap.properties)
truncates last character of the string value.

############################################################
ISAPI_REDIRECT.PROPERTIES
# Configuration file for the Jakarta ISAPI Redirector

# The path to the ISAPI Redirector Extension, relative to the website
# This must be in a virtual directory with execute privileges
extension_uri=/mywebapp/isapi_redirect.dll

# Full path to the log file for the ISAPI Redirector
log_file=jk_iis.log

# Log level (debug, info, warn, error or trace)
log_level=debug 

# Full path to the workers.properties file
worker_file=workers.properties

# Full path to the uriworkermap.properties file
worker_mount_file=uriworkermap.properties
############################################################

... all files do exist in the same C:\Tomee\connectors\ folder.

If I specify absolute paths (C:\Tomee\connectors\uriworkermap.properties),
everything works fine.

If I use relative paths with log and config file outside of dll/properties
files folder, no log file generated making it difficult to debug.

If I use relative paths with all files in the same folder, a jk_iis.lo (missing
the g) file is created with the following output:

file C:\Tomee\connectors\conf\uriworkermap.properties (errno=2, err=No such
file or directory).

... whereas the initial declaration of file location is correct but subsequent
uri_worker_map load ignores the "..\" relative declaration. 

Workaround:  
  1.  Use absolute paths.
  2.  Add a superfluous character in your isapi_redirect.properties file so it
is truncated instead of the real value.  e.g.  "uriworkmap.propertiesx"

I hope this enough information to find the issue.  If I can help with other
information or testing, let me know.
Thanks
Brad
