All-
I've just pushed this CPAN Developers release, a.k.a. PDL-2.4.10 rc3,
to CPAN and it should be appearing at a CPAN mirror near you
within the next couple of days. See below for the first draft of the
full release notes.
At this point we expect (and permit) no further significant code
changes and work between now and the release date should
focus on testing (especially for modules with external library
dependencies, including fortran and ExtUtils::F77), documentation,
and completion of the PDL Book which is planned to be released
at the same time as PDL-2.4.10.
Contributions in testing, documentation, web page updates, and
the PDL book are welcome!
Thanks,
Chris Marshall (PDL-2.4.10 release manager)
Release Notes for PDL 2.4.9_993 --------------------------
General Notes:
* A.k.a. PDL-2.4.10 release candidate 3
* Preliminary draft release notes follow.
* All focus now is on testing, documentation, web page
updates, and writing the PDL Book...
- Manual build/install is recommended although the
cpan shell may be used by specifying the distribution
path rather than just the module name, e.g.:
cpan> get CHM/PDL-2.4.9_993.tar.gz
cpan> make CHM/PDL-2.4.9_993.tar.gz
cpan> test CHM/PDL-2.4.9_993.tar.gz
cpan> look CHM/PDL-2.4.9_993.tar.gz
Highlights:
* General cleanup of code, including restructuring for clarity.
* List output from whichND is now deprecated. whichND now returns
a piddle of coordinates in all cases with a warning when a list
context is detected. See the docs for work-arounds to your code.
* PDL::IO::Misc now has better support for handles that are not
files (e.g., pipes or standard input) for rgrep, rcols,...
* Added bad value support to pctover and oddpctover.
This was sf.net feature #3328001.
* New whereND routine provides the same functionality as where
but with support for multi-dimensional masks and implicit
threading over higher dimensions. This was sf.net feature
request #3390043.
* Many bugs fixed.

* PDL::Constants now provides: E, PI, I and J and is loaded but the
default.perldlrc. You'll need to add it by hand if you wish to
use the new constants.
* default.perldlrc now sets $PDL::IO::FlexRaw::writeflexhdr by
default so that writeflex() to a filename automatically writes
the header file. This is different from the previous behavior
but it seems to "do what you mean". Feedback welcome!
* PDL::NiceSlice now has a new engine based on Filter::Simple which
is smarter about only applying the slicing source filter to syntax
occurring outside of POD, comments, and quotelike strings. The
new implementation is available for *files* by setting the
PDL_NICESLICE_ENGINE environment variable to 'Filter::Simple'.
Work is underway to port the new implementation to the PDL shells.
Once this task is completed, the new engine will become the
default source filter and the PDL_NICESLICE_ENGINE environment
variable check will be removed.
* There is experimental support for PDL::NiceSlice syntax in the
perl debugger (i.e., perl -d). Just set the PERL5DB environment
variable to 'BEGIN { require "PDLdb.pl" }' to use niceslice
from the debugger command line. NOTE: if PERL5DB is already
set, you'll need to adjust the above recipe accordingly.
* Better handling of build configuration options from perldl.conf
as well as improvements in the detection of external dependencies.
* PDL::IO::Browser now builds in many cases (but not all, which
is why the default is not to build). If you try it, let us know
how it goes. Just edit the value of WITH_IO_BROWSER in your
perldl.conf before configuring the build.
* perldl.conf has some new fields added: POSIX_THREADS_INC and
POSIX_THREADS_LIBS to specify locations of your pthread header
file and library, PDL_CONFIG_VERSION to track future changes
to this file, PDLDOC_IGNORE_AUTOLOADER to control pdldoc behavior,
and PDL_BUILD_DIR/PDL_BUILD_VERSION to provide a way to query
this information at run-time post-install.
If you are using a private perldl.conf file, please be
sure to update with the additional fields as we don't yet
detect that automatically.
* PDL::PP has seen some significant improvements including
code cleanup, improved documentation, and code refactoring
for comprehension. There is a new PDL::PP::pp_line_numbers()
routine which enables line # traceback for errors and warnings
from PP code.
* Improved error output from the pdl2 shell via the new
CleanErrors plugin which filters out the non-PDL part
of the error output leading to *much* more concise and
helpful reports.
* The pdl() constructor now accepts a string argument which
allows for writing pdls using a matlab/octave style
syntax as well as cutting and pasting from interactive
session output to create pdls initializations for scripts
and program files.
The new constructor also allows for inf, nan, and bad to
generate the appropriate values (case insensitive), e.g.,
$bad = pdl q[1 2 3 bad 5 6]; # Set fourth element to the bad value
$bad = pdl q[1 2 3 BAD 5 6]; # ditto
$bad = pdl q[1 2 inf bad 5]; # now third element is IEEE infinite value
$bad = pdl q[nan 2 inf -inf]; # first value is IEEE nan value
This is new functionality so feedback and problem reports
are welcome.
* PDL::Image2D has new routines: pnpoly() to determine the points
in a polygon from the sequence of vertex coordinates, and
cc4compt() for 4-component labeling of a binary image.
* PDL now supports pdls larger than 2GiB. The element count
is still an int internally so the number of elements must
be less than 2**31.
* POSIX threads (pthreads) are supported for win32 and cygwin
platforms. Pthreads are now available for all PDL platforms.
* New PDL::ParallelCPU module provided automatic distribution
of implicit thread loops across a number of processors. Now
you can watch a heavy PDL computation maximize the load for
*all* your processors. See the docs for how to configure this
feature and how to adjust your calculations to best take
advantage of this feature.
* PDL::Graphics::PLplot now works with the latest release of the
PLplot library and has improved configuration and build
handling. Feedback welcome.
* rcols and wcols now use the same convention for multi-column
input and output: dim0 is *always* the data dimension and
dim1 corresponds to the columns in the file. This adjustment
makes them the inverse operation for 2-D piddles.
* The ADEV calculation in statsover has been corrected along
with the documentation.
* PDL::Graphics::TriD now builds with the perl OpenGL configured
for the native win32 OpenGL API, cygwin+w32api. The software
Mesa/X11 render is not required although you will need to rebuild
your PDL if you change the underlying POGL install interface.
Also, a new demo by Mark Baker has been added to 'demo 3dgal',
* Various enhancements to FITS handling, including:
- add map() fix for nonlinear FITS headers
- Enable hdrpcy in rfits for Rice-compressed images
* Test suite improvements to provide better diagnostics from
failures and to make tests more correct to avoid "false fails"
in the test reports. Various tests have been migrated to use
File::Temp::tempdir and File::Temp::tempfile to improved the
robustness for temporary files and directories used for
testing.
* Update ExtUtils::MakeMaker required version to 6.31 to support
the new standard of INSTALL_BASE to configure for a local
perl/PDL module installation.
* Update Text::Balanced required version to 1.89. This is the
version present in perl 5.8.0 (the minimum required for PDL)
so this change in requirement is not expected to affect any
PDL users.
* pdldoc now searches your PDLLIB path for PDL::AutoLoader docs
in addition to the pre-extracted documentation database. This
makes pdldoc give the same output as the help command in the
PDL shells.
* Many updates and additions to the PDL documentation.
* Devel::CheckLib is being used in more places during the
PDL configuration stage. We plan to make this the standard
baseline for dependency library detection going forwards.
The included copy of Devel::CheckLib has been updated to 0.95.
* A new unified implementation of barf/warn for PDL removed code
duplication. barf is now defined in both PDL::Core and in PDL.
PDL::cluck is added as an analog of Carp::cluck (as PDL::barf
is an analog of Carp::confess). barf() now generates its stack
trace by hooking into Carp::confess on both the Perl and C sides.
* Various fixes for PDL::Transform
- fix inverse in perspective()
- fix t_cubic parameter parsing
- fix handling of multiple PCi_j systems in the piddle header
* Added SIGPIPE handlers to cases where PDL uses pipes to/from
external processes (such as ffmpeg or some NetPBM image
converter programs). This should make PDL "SIGPIPE safe" by not
exiting when a PDL piped IO output process quits (e.g., as when
called from within the perldl/pdl2 shell).
