Subject DO NOT REPLY [Bug 49369] New: mod_deflate output filters pass empty brigades down the filter chain
Date Tue, 01 Jun 2010 17:07:46 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=49369

           Summary: mod_deflate output filters pass empty brigades down
                    the filter chain
           Product: Apache httpd-2
           Version: 2.3-HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: trivial
          Priority: P2
         Component: mod_deflate
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: mdsteele@google.com


If mod_deflate's output filters are passed an empty brigade, they will pass the
empty brigade to the next filter in the chain.  This is contrary to what is
recommended by the "Guide to writing output filters" on the httpd website
<http://httpd.apache.org/docs/2.3/developer/output-filters.html>.  According to
that page, empty brigades should be suppressed; upon seeing an empty brigade,
the filter should simply return APR_SUCCESS rather than calling
ap_pass_brigade.  This would be a trivial (2-line) change to mod_deflate.
