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: mdste...@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.
