http://issues.apache.org/bugzilla/show_bug.cgi?id=38889 Summary: mod_jk disregards configuration file order of JkMount Product: Tomcat 5 Version: 5.5.15 Platform: All OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: Native:JK AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I've been trying out the new version of mod_jk (1.2.15) I've been working on upgrading our mod_jk from 1.2.9 to 1.2.15. (We use mod_jk primarily on Linux, in conjunction with apache 2.0.53 and tomcat 5.5.15). During testing, I noticed several cases of JkMount mappings going to the wrong set of workers. By `wrong', I mean `not the same workers as 1.2.9 would have chosen'; this behavior is reproducible with both the apache 1.3 and 2.0 versions of mod_jk Here is an example: Given JkMount directives: JkMount /k/* worker_k JkMount /s/* worker_s JkMount /m/* worker_m JkMount /h/* worker_h JkMount /*.jsp worker_default These mount points effectively represent 5 different applications under a single VirtualHost; and they're handled by 5 different groups of tomcats. I'll make a request for the uri "/this-uri-wont-match". Here is the portion of JkLogFile that attempts matching: [Tue Mar 07 16:20:40 2006] [16809:0000] [debug] map_uri_to_worker::jk_uri_worker_map.c (449): Attempting to map URI '/this-uri-wont-match' from 5 maps [Tue Mar 07 16:20:40 2006] [16809:0000] [debug] map_uri_to_worker::jk_uri_worker_map.c (461): Attempting to map context URI '/*.jsp' [Tue Mar 07 16:20:40 2006] [16809:0000] [debug] map_uri_to_worker::jk_uri_worker_map.c (461): Attempting to map context URI '/k/*' [Tue Mar 07 16:20:40 2006] [16809:0000] [debug] map_uri_to_worker::jk_uri_worker_map.c (461): Attempting to map context URI '/s/*' [Tue Mar 07 16:20:40 2006] [16809:0000] [debug] map_uri_to_worker::jk_uri_worker_map.c (461): Attempting to map context URI '/m/*' [Tue Mar 07 16:20:40 2006] [16809:0000] [debug] map_uri_to_worker::jk_uri_worker_map.c (461): Attempting to map context URI '/h/*' I see that the code is attempting a `longest-pattern-first' match. However, the side effect of this is uri's like /m/some.jsp /h/some-other.jsp /s/yet-another.jsp .... become unreachable. Because mod_jk 1.2.15 uses pattern length, and not *configuration file* order, there are circumstances where it will never match the desired servlet container. Commenting out the call to worker_qsort() (line 297 of jk_uri_worker_map.c -- diff attached) makes the issue go away. Would it be possible to go back to matching based on configuration file order? -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
