- Updating package for p5 module Devel::NYTProf from 2.09 to 2.10
- Adding perl5 license as license
Upstream changes:
Changes in Devel::NYTProf 2.10 (svn r774) 18th June 2009
Fixed call count for XSubs that was one too high.
Fixed enable_profile() after fork thanks to delamonpansie
http://code.google.com/p/perl-devel-nytprof/issues/detail?id=15
Fixed to use correct scripts during test and so avoid permissions
issues, thanks to David Golden.
Fixed suprious "Unable to determine line number" warnings
when using options like -p, -n, -Mfoo.
Changed enable_profile() to discard the time spent since
profile was disabled.
Changed NYTPROF env var parsing to allow backslash to escape
colons, for Windows, thanks to Joshua ben Jore.
Added license, homepage, bugtracker, repository and MailingList
resources to META.yml thanks to Michael G Schwern.
Added nytprofcg utility to generate callgrind data for
viewing via Kcachegrind, thanks to Chia-liang Kao.
Upstream changes:
Changes in Devel::NYTProf 2.09 (svn r733) 29th March 2009
Added support for modules using AutoLoader, e.g., POSIX & Storable,
to fix the "Unable to open '... (autosplit into ...)'" warnings.
Fixed report filename generation to remove colons,
for Windows, reported by Adam Kennedy in rt bug #43798.
Fixed report filename generation to remove dots, for VMS.
Fixed savesrc option which wasn't safe and reliable.
Added missing t/test22-strevala.t to MANIFEST.
Extended testing to exercise compress and savesrc options.
Ported to VMS, thanks to Peter (Stig) Edwards:
Renamed t/\d\d.test.t files to t/\d\d_test.t
t/test*.pm.x files to t/test*.pm_x
t/test*fork.\d.* files to t/test*fork-\d.*
.js and .css file to only have one period/dot
for greater portability. VMS ODS-2 files can only have
one period/dot.
Added t/92-file_port.t as a developer-only and
request-using-ENV test, to help maintain portable files,
currently .indent.pro and .perltidyrc fall foul of portable
filename characters as defined by ANSI C and perlport.
NYTProf.xs's open_output_file use mode 'wb' and not 'wbx'
to avoid unsupported error when on VMS.
Upstream changes:
* Changes in Devel::NYTProf 2.08
** Core:
- Added optimize=0 option to disable the perl optimizer
so you can see more accurate statement execution counts
for some kinds of constructs.
- Added savesrc=1 option to copy source code into the profile
so reports are not affected by changes to the source files.
- Added ability for DB::enable_profile() to specify a new file
for profile data to be written to.
** Reporting:
- Time spent within nested string evals is accounted for.
- Fixed searching @INC for source files for reports.
- Dramatically increased performance of nytprofhtml
relative to the 2.07 version.
- Many tables in html reports are sortable by clicking on header columns
(requires JavaScript, uses jQuery and tablesorter.js)
- Statement timings are now shown as integers in appropriate
units: seconds, milliseconds, microseconds or nanoseconds.
- Hovering over times in subroutine or file summary tables
now shows the percentage time.
- Improved HTML conformance thanks to Leland Johnson.
Packages Collection.
The Perl 5 module Devel::NYTProf is a powerful feature-rich perl
source code profiler.
- Performs per-line statement profiling for fine detail
- Performs per-subroutine statement profiling for overview
- Performs per-block statement profiling (the first profiler to do so)
- Accounts correctly for time spent after calls return
- Performs inclusive and exclusive timing of subroutines
- Subroutine times are per calling location (a powerful feature)
- Can profile compile-time activity, just run-time, or just END time
- Uses novel techniques for efficient profiling
- Sub-microsecond (100ns) resolution on systems with clock_gettime()
- Very fast - the fastest statement and subroutine profilers for perl
- Handles applications that fork, with no performance cost
- Immune from noise caused by profiling overheads and I/O
- Program being profiled can stop/start the profiler
- Generates richly annotated and cross-linked html reports
- Trivial to use with mod_perl - add one line to httpd.conf
- Includes an extensive test suite
- Tested on very large codebases
NyTProf is effectively two profilers in one: a statement profiler,
and a subroutine profiler.
