[Bug 60964] New: EXEC_ON_READ directives can't log at levels above
DEFAULT_LOGLEVEL
https://bz.apache.org/bugzilla/show_bug.cgi?id=60964
Bug ID: 60964
Summary: EXEC_ON_READ directives can't log at levels above
DEFAULT_LOGLEVEL
Product: Apache httpd-2
Version: 2.5-HEAD
Hardware: PC
OS: Linux
Status: NEW
Severity: minor
Priority: P2
Component: Core
Assignee: bugs@httpd.apache.org
Reporter: jchampion@apache.org
Target Milestone: ---
Filing a placeholder so I don't forget about this...
If a directive is running as EXEC_ON_READ, any attempts to log at a level above
DEFAULT_LOGLEVEL will silently fail, even if the LogLevel is tuned at the
appropriate level for that module. There are two unrelated effects that cause
this:
1) If we're not logging against a server_rec (or the server_rec is NULL), the
core logging code refuses to log anything above ap_default_loglevel, unless
it's a NOTICE or the server has been compiled with -DDEBUG.
2) If we are logging against a server_rec, the LogLevel directive will still
not have been parsed by the time EXEC_ON_READ directives are being run. So
DEFAULT_LOGLEVEL will be the highest level possible.
This seems to affect only LoadModule and LoadFile, which try to log what files
they're loading at DEBUG level. It would have affected mod_remoteip's
RemoteIPTrustedProxyList and RemoteIPInternalProxyList, if ap_pcfg_openfile's
debug logging weren't already wrapped in an #ifdef DEBUG.

[Bug 60964] EXEC_ON_READ directives can't log at levels above
DEFAULT_LOGLEVEL
Posted by bu...@apache.org.
https://bz.apache.org/bugzilla/show_bug.cgi?id=60964
--- Comment #1 from Jacob Champion <jc...@apache.org> ---
Note that the default loglevel can be explicitly set with -e. It's just
surprising that changing a directive to EXEC_ON_READ forces it to use a
different LogLevel from the rest of the server.
