DO NOT REPLY [Bug 52056] New: Wrong HTTP status 200 in log instead
of 500/503
https://issues.apache.org/bugzilla/show_bug.cgi?id=52056
Bug #: 52056
Summary: Wrong HTTP status 200 in log instead of 500/503
Product: Tomcat Connectors
Version: 1.2.32
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_jk
AssignedTo: dev@tomcat.apache.org
ReportedBy: avenger@dmz.org.ua
Classification: Unclassified
Created attachment 27818

default value for request_rec.status
In case JkLogFormat contains "%s" (Request HTTP status) placeholder - it is not
always shows correct codes.
If there are no workers available - mod_jk records 200 (HTTP_OK) in logs, while
httpd records and shows 503 error:
<<access.log:
172.16.16.1 - - [19/Oct/2011:10:35:01 +0300] "GET / HTTP/1.1" 503 323
<<mod_jk.log:
[Wed Oct 19 10:35:01.906 2011] [2053:3086162528] [error]
ajp_send_request::jk_ajp_common.c (1630): (devel) connecting to backend failed.
Tomcat is probably not started or is listening on the wrong port (errno=111)

ajp_service::jk_ajp_common.c (2626): (devel) connecting to tomcat failed.
[Wed Oct 19 10:35:01.906 2011] 0.100435 - vm201.int GET / HTTP/1.1 200
[Wed Oct 19 10:35:01.906 2011] [2053:3086162528] [info] jk_handler::mod_jk.c
(2678): Service error=-3 for worker=devel
It seems that request.status (the one that got recorded in logs) have default
value of 200 and is updated only in jk_ajp_common.c::ajp_get_reply(). But this
function never hit if jk_ajp_common.c::ajp_send_request() returns anything
besides JK_TRUE.
Maybe request.status variable should be initialized the same way as is_error
variable in jk_handler() - default value HTTP_INTERNAL_SERVER_ERROR, and all
subsequent functions will alter its value to one they needed. With such
modification mod_jk will put 500 error in case request failed before it have a
chance to connect to backend (see attachment).

mod_jk workers properties
Sorry, forget about versions:
mod_jk - 1.2.32 (latest)
httpd - 2.2.21
access.log - default apache access log, configured with:
CustomLog /var/log/httpd/access.log combined
mod_jk.log - default mod_jk log file:
JkLogFile /var/log/httpd/mod_jk.log
JkRequestLogFormat "%T %R %V \"%r\" %s"
Configuration is simple - any unreachable worker will work. See attachments for
example configuration.

Fixed in r1187906. Will be part of mod_jk 1.2.33.
To fix the problem, the JK request log was refactored to use the standard
request log hook. You can apply the changes in r1187906 on top of 1.2.32 to
test it.
regards,
Rainer

1. Versions of everything = ?
There are various fixes in various Tomcat versions and the behaviour may be
different.
2. What exactly are those files, "access.log" and "mod_jk.log"?
Or better provide exact steps & configuration to reproduce this.
