Subject: Patch to mod_perl 1.26: "error-notes" support
Hello Doug & All --
One of my programmers (Dave Kaufman) brought to my attention a small but
useful feature which is present in mod_cgi, but missing from
Apache::Registry. When running via mod_cgi, if execution of a CGI
application fails, an error message will be propagated to an environment
variable, "ERROR_NOTES". This environment variable can be used by a custom
"ErrorDocument" to assist in quality assurance.
This variable is actually propagated, by http_request.c (confirmed in Apache
1.3.20), from an Apache "note" whose key is "error-notes". A number of
Apache handlers use the "error-notes" attribute to pass along human-readable
exception data.
Following is a patch I wrote (against mod_perl 1.26, Apache::Registry
version 2.01) which causes Apache::Registry to participate in this scheme.
I hope you find it sufficiently useful to include in the next version of
mod_perl.
Warmest regards,
-Jesse-
