VCP::Debug - debugging support for VCP
Debugging support for VCP. Enabled by setting the environment variable
VCPDEBUG=1.
- debug
-
debug $foo if debugging $self ;
Emits a line of debugging (a "\n" will be appended).
Use to avoid the "\n". Any undefined parameters will be
displayed as "<undef>".
- debugging
-
debug "blah" if debugging ;
Returns TRUE if the caller's module is being debugged
debug "blah" if debugging $self ;
debug "blah" if debugging $other, $self ; ## ORs the arguments together
Returns TRUE if any of the arguments are being debugged. Plain
strings can be passed or blessed references.
- profiling
- Returns true if VCP is profiling itself compared to shell command
performance.
This is different from using perl's profilers (-d:DProf and
the like); this profiling tracks the operation of some of VCP's
internals and also how long is spent waiting for child processes to
complete.
- $VCP::Debug::profile_category
- Sets the category for the next profile_start and profile_end pair of
calls:
local $VCP::Debug::profile_category = "p4 files" if profiling;
- profile_start
- Notes the current time as the start of a profiling interval.
Defaults to the category
$profile_category if none passed.
- profile_end
- Notes the current time as the end of a profiling interval.
Defaults to the category
$profile_category if none passed.
- profile_group
- Called with the prefix of a set of profile categories to sum up and emit
subtotals for.
