[Bug 58304] New: Unexpected Warnings from Macro Use in 2.4
https://bz.apache.org/bugzilla/show_bug.cgi?id=58304
Bug ID: 58304
Summary: Unexpected Warnings from Macro Use in 2.4
Product: Apache httpd-2
Version: 2.4.16
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Core
Assignee: bugs@httpd.apache.org
Reporter: tom.browder@gmail.com
Starting with 2.4.12 and still existing in 2.4.16, when using a Macro
definition for virtual hosts, I get repeated warnings to stdout that the macro
variables are undefined every time apache is started or during a syntax check:
root@dedi2:/home/tbrowde# apachectl -t

Syntax OK
I am using three macros that are defined in the httpd.conf file as follows:
<Macro VHOST_NONTLS ${PROJECT} ${TLD}>
<VirtualHost *:80>
ServerName ${PROJECT}.${TLD}
ServerAlias *.${PROJECT}.${TLD}
DocumentRoot /home/web-server/${PROJECT}.${TLD}/public
</VirtualHost>
</Macro>
Use VHOST_NONTLS niceville.pm org
UndefMacro VHOST_NONTLS
<Macro VHOST_FREE_CERT_TLS ${PROJECT} ${TLD}>
<VirtualHost *:80>
ServerName ${PROJECT}.${TLD}
ServerAlias *.${PROJECT}.${TLD}
# enforce ssl/tls
Redirect Permanent / https://${PROJECT}.${TLD}/
</VirtualHost>
</Macro>
Use VHOST_FREE_CERT_TLS computertechnwf org
UndefMacro VHOST_FREE_CERT_TLS
<Macro VHOST_WILDCARD_TLS ${PROJECT} ${TLD}>
<VirtualHost *:80>
ServerName ${PROJECT}.${TLD}
ServerAlias *.${PROJECT}.${TLD}
# enforce ssl/tls
Redirect Permanent / https://${PROJECT}.${TLD}/
</VirtualHost>
# ...
</Macro>
Use VHOST_WILDCARD_TLS highlandsprings61 org
UndefMacro VHOST_WILDCARD_TLS

This fix appears to have been in Apache 2 for quite some time.
I'm marking RESOLVED/Fixed.
This appears to remedy bug 59299.
I've filed bug 66153 related to the mod_macro documentation.

--- Comment #1 from Marc Stern <ma...@approach.be> ---
${VAR} is interpreted as a defined variable
(http://httpd.apache.org/docs/2.4/mod/core.html#define). It's equivalent to
%{VAR}.
mod_macro uses the syntax $var but also ${var}, which is mandatory if you want
the variable to be a part of a string, like in "${var}abc".
The syntax clashes with the Define directive, so it should be changed. Ans
%{var} clashes with mod_rewrite.
This doe not only give a warning but could lead to a real mismatch between
something defined as a local parameter and somebody else defining it at a
global level as a defined config variable.
To make interpolation not clash with another module, we should use another
character (instead of an existing one or on top of?) like &{var}.

Created attachment 34013

Add warning about syntax clash
In case a macro argument uses the syntax ${...}, adds a warning that it clashes
with the 'Define' directive
