5 - To avoid core dumps, increase stack size by 10 instead of 5.
6 - Assert that g_profstack is large enough when DEBUGGING is defined
13 Newer perls: Add PERL_POLLUTE and dTHR.
16 This version of DProf should work with older Perls too, but to get
17 full benefits some patches to 5.004_55 are needed. Patches take effect
18 after new version of Perl is installed, and DProf recompiled.
20 Without these patches the overhead of DProf is too big, thus the statistic
26 - correct defstash to PL_defstash
31 - documentation updated
36 Jason E. Holt and Ilya Zakharevich:
38 - will not wait until completion to write the output, size of buffer
39 regulated by PERL_DPROF_BUFFER, default 2**14 words;
43 - smarter in fixing garbled profiles;
44 - subtracts DProf output overhead, and suggested profiler overhead;
45 - new options -A, -R, -g subroutine, -S;
48 - 7x denser output (time separated from name, ids for subs);
49 - outputs report-write overhead;
50 - optional higher-resolution (currently OS/2 only, cannot grok VMS code);
51 - outputs suggested profiler overhead;
53 - handles PERL_DPROF_TICKS (on OS/2, VMS may be easily modified too)
55 Jun 14, 97 andreas koenig adds the compatibility notes to the README
56 and lets the Makefile.PL die on $] < 5.004.
58 Jun 06, 97 andreas koenig applies a patch by gurusamy sarathy because
59 Dean is not available for comments at that time. The patch is available
60 from CPAN in the authors/id/GSAR directory for inspection.
64 - added Ilya's patches to fix "&bar as &bar(@_)" bug. This also fixes
65 the coredumps people have seen when using this with 5.003+.
71 - remove special case for bug.t
75 - smarter r.e. to find VERSION in Makefile (for MM5.27).
79 - keep pid of profiled process, if process forks then only the
80 parent is profiled. Added test4 for this.
86 - updated manpage, point to DProf for raw profile description.
88 - update manpage, update raw profile description with XS_VERSION.
89 - update manpage for AUTOLOAD changes.
91 - smart handling of &AUTOLOAD--looks in $AUTOLOAD for the sub name.
92 this fixes one problem with corrupt profiles.
97 - added -E/-I for exclusive/inclusive times
98 - added DPROFPP_OPTS -- lazily
99 - added -p/-Q for profile-then-analyze
100 - added version check
102 - pull dprofpp's version id from the makefile
104 - added version to bootstrap
106 - updated doc, DProf and -w are now friendly to each other
109 - added Tim's patch to check for DBsub, avoids -MDevel::DProf coredump
110 - turn off warnings during newXS("DB::sub")
112 - added Tim's patch to ignore Loader::import in results
113 - added Tim's patch to aid readability of test?.v output
