Changes - Revision history for DashProfiler

RELEASES

DashProfiler 1.13 - r50 - May 8th 2008

Changed DashProfiler subs that may be used as Apache handlers
  to return -1 (DECLINED).

DashProfiler 1.12 - r48 - Mar 25th 2008

Fixed period_exclusive sample calculation of overheads.
Fixed period_sample to be disabled until start_period_sample() called.
Slight performance boost (0.000015 instead of 0.000017).

DashProfiler 1.11 - r45 - Mar 24 2008

Now ~17% faster (cheaper) when using DBI >= 1.603.
Make tests more robust and work with Perl 5.10.

DashProfiler 1.09 - r43 - Feb 20 2008

Added $sample->current_sample_duration method.
Added $core->period_start_time method.
Added DashProfiler->profile_names method.
Added DashProfiler->set_precondition method.
Added DashProfiler::Core->estimate_sample_overheads.
Added automatic measurement of sample overhead time.
Updated DashProfiler::Apache to use set_precondition
  to start sample periods only for initial requests.
Updated DashProfiler::Apache docs to suggest PerlInitHandler
  instead of PerlPostReadRequestHandler.

DashProfiler 1.08 - r36 - Sept 11 2007

Fixed fatal error in visit_profile_nodes() for DBI profiles with no Data.

Changed propagate_period_count() to not reset period_count.
Changed to increment period_count in end_sample_period() not start_sample_period().
Changed start_sample_period() to not call end_sample_period() automatically.
  So now multiple start_sample_period() calls without end_sample_period() calls
  are harmless - the period runs from the most recent start_sample_period() call.

Added period_strict_start and period_strict_end attributes to control how
  missing/multiple start_sample_period() & end_sample_period calls are handled.
  The attributes can be code refs which are called when needed.
Added extra_info attribute for use by scripts to carry any extra information.

DashProfiler 1.07 - r32 - Aug 16 2007

Added DashProfiler::Apache
Added -optional syntax to DashProfiler::Import

DashProfiler 1.06 - r29 - Aug 14 2007

Fixed DashProfiler::Import :optionally to still export stubs
Changed DashProfiler reset_all_profiles() to not call start_sample_period_all_profiles().
Changed DashProfiler::Auto to use file name not full path.
Changed DashProfiler::Core end_sample_period() to do nothing if no period is active.
Added more docs, especially to UserGuide and Auto.

DashProfiler 1.05 - r25 - Aug 10 2007

Added :optional to DashProfiler::Import
Added dbi_profile_args to pass extra args to dbi_profile_class->new().

Removed spool_directory arg (use dbi_profile_args => { Dir => ... } instead)
Set local $ENV{DBI_AUTOPROXY} to avoid risk of problems
Generalized get_dbi_profile() to take a '*'
start_sample_period and end_sample_period check for overlaps
end_sample_period now returns period_sample DBI Profile object not dbh
