Subject: Fixed the EOS handling for partial SSI directives at the end of
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=558e0d41769955e824c6db17d8d266d38090808f;p=apache

Fixed the EOS handling for partial SSI directives at the end of
brigades.  (This was causing us to produce no output, not even
an HTTP response header, for a document containing an unterminated
"<!--#" directive

 Changes with Apache 2.0.40
 
+  *) Fixed a mod_include error case in which no HTTP response was sent
+     to the client if an shtml document contained an unterminated SSI
+     directive [Brian Pane]
+
   *) Improve ap_get_client_block implementation by using APR-util brigade
      helper functions and relying on current filter assumptions.
