Listed from low level to high level: emerg(), alert(), crit(), +error(), warning(), notice(), info(), debug(). The only different +function is warning(), since warn is already taken by Perl. + +The module provides another trace function called todo() which is +useful for todo items. It has the same level as I (the +highest). + +There are two more variants of each of these functions. If the +I<_mark> suffix is appended (e.g., I) the trace will start +with the filename and the line number the function was called from. If +the I<_sub> suffix is appended (e.g., I) the trace will +start with the name of the subroutine the function was called from. + +If you have C installed the diagnostic messages will +be colorized, otherwise a special for each function prefix will be +used. + +If C is installed and you pass a reference to a variable +to any of these functions, the variable will be dumped with +C. + +Functions whose level is above the level set in +C<$Apache::TestTrace::Level> become NOPs. For example if the level is +set to I, only alert() and emerg() functions will generate the +output. The default setting of this variable is I. Other +valid values are: I, I, I, I, I, +I, I, I. + +Another way to affect the trace level is to set +C<$ENV{APACHE_TEST_TRACE_LEVEL}>, which takes effect if +C<$Apache::TestTrace::Level> is not set. So an explicit setting of +C<$Apache::TestTrace::Level> always takes precedence. + +By default all the output generated by these functions goes to +STDERR. You can override the default filehandler by overriding +C<$Apache::TestTrace::LogFH> with a new filehandler. + +When you override this package's global variables, think about +localizing your local settings, so it won't affect other modules using +this module in the same run. + +=head1 TODO + + o provide an option to disable the coloring altogether via some flag + or import() + +=head1 AUTHOR + +Stas Bekman with contributions from Doug MacEachern + +=cut + -- cgit v1.2.3
