Release Notes for PDL 2.4.9 -------------------------- General Notes: * Fixes a couple of surprise bugs that were discovered immediately with the PDL-2.4.8 release. * See Also: the Release Notes for PDL-2.4.8 below Highlights: * Fix sf.net bug #3267408 "t/slice.t crashes in tests 68-70 for BSD" * Fix sf.net bug #3190227 "PDL build fails with parallel GNU make -j3 -j3" * Fixed various tempfile name generation problems by switching to File::Temp instead of hand rolled solutions. This is the recommended approach going forward. * Force Convert::UU usage for BSD to work around a t/dumper.t failure on MirBSD. Release Notes for PDL 2.4.8 -------------------------- General Notes: * The deprecated Karma imaging library support code has been removed from the PDL distribution. * Perl OpenGL (POGL) is now the only build option for 3-D graphics support in PDL. The POGL build has proven to be portable and reliable. This prepares TriD graphics development for the next stage of re-factoring for support and new features. * Many improvements to the PDL configuration, build and test process make this the most robust PDL yet. * PDL::IO::FlexRaw now supports automatic header file creation when writeflex() is given a filename argument for writing. readflex/writeflex/mapflex now support reading and writing piddles with bad values in them. * New PDL::Constants module provides PI and E. * PDL::Complex now supports in-place operations. * Added $PDL::toolongtoprint to set the maximum piddle size allowed to print as a string. This was added to the default.perldlrc to make it easier to discover by users. * wmpeg() from PDL::IO::Pic uses the new ffmpeg back-end and can create many additional file formats beyond MPEG alone, including MP4 and animated GIF. See the documentation for details. * Lots of improvements to the documentation, overall usability and many bugs fixed! Highlights: Build and Test Enhancements: * Karma support code has been *removed* from the PDL distribution The last stable PDL distribution with Karma code was be PDL-2.4.7. * You must use the Perl OpenGL module to build the PDL 3-D graphics module, PDL::Graphics::TriD. OPENGL_LIBS, OPENGL_INC and OPENGL_DEFINE are no longer used by perldl.conf for the configuration process. * Added a check for mis-installed PROJ4 libraries. If the library does not initialize (even if present) then PDL will not build the PROJ4 modules. This is sf.net feature #3045456. * GD, HDF, PROJ4, OpenGL, and GSL tests will not be run unless the corresponding module was configured to be built. This addresses the possibly mysterious test failures caused by previous PDL installations in the perl path at build time. * Use of the Test::More TODO {} blocks allows tests for known bugs to be added to the test suite without causing the suite to fail. This replaces the previous SKIP_KNOWN_PROBLEMS option and should better enable test first development and debugging. * utils/perldlpp.pl is a new script for off-line source filtering to pre-filter PDL source files with NiceSlice constructs. This allows PDL to use NiceSlice constructs in the core functionality while still allowing PDL to work in environments where source filters are not supported. * The 'perl Makefile.PL' response to detecting another PDL in the build path has changed. If such a pre-existing PDL installation is detected, the user is warned *but* configuration and build will proceed nonetheless. * Clean-up and fixes to demos and tests for reliability and portability. Documentation: * Added INTERNATIONALIZATION file with i18n notes. PDL does yet not have internationalization support beyond that provided by perl itself. * Cleared up the documentation on when to use lu_decomp and versus lu_decomp2. Now that lu_decomp is threaded, it is the preferred implementation. * wmpeg() with the ffmpeg converter supports generation of many different output video file formats including MPEG, MP4, and animated GIF. Documentation on these uses were added. * New example code refresh.pdl in Example/PLplot to provide for PLplot, some of the same functionality as in PDL::Graphics::PGPLOT. * Other documentation updates for clarity and correctness. New Features or Functionality: * New PDL::Constants module providing PI and E (so far) * Inplace support added for PDL::Complex operations * pdldoc and the pdl2/perldl help commands now print all matches by default when multiple matches are found. * A do_print command was added to the pdl2 shell which toggles the input mode between printing and not printing the return value of each command. * readflex/writeflex/mapflex now support reading and writing piddles with bad values in them. This was sf.net feature request #3028127, "add badvalue support to FlexRaw". * writeflex now supports automatically calling the writeflexhdr() routine if you have set the variable $PDL::FlexRaw::writeflexhdr to a true value and are writing to a file given by filename as argument. * Updated the error handling for GSL::INTERP to match other GSL module usages. * Applied sf.net patch #3209075 IO::HDF square sds * New binary blob support in PDL::IO::GD::OO Bugs Fixed: * Applied Christian Soeller's patch for FFTW on 64-bit systems. This resolves bug #3203480 "t/fftw.t fails on 64-bit systems". * Fixed sf.net bug #3172882 re broken threading in inv(). inv() and lu_backsub() now handle threading. Updated documentation for lu_decomp, lu_deomp2, and lu_backsub. * Fixed sf.net bug #3171702 "missing podselect command breaks PDL build" * Fixed sf.net bug #3185864 (bad adev in statsover) * Fixed sf.net bug #3139697: fixed imag2d() to work better with Mac OS X GLUT and not just FreeGLUT. * Fixed uniqind bug #3076570 * Fixed SF bug #3057542: wmpeg doesn't error on missing ffmpeg program. Now wmpeg returns 1 on success and undef on error. If ffmpeg is not in PATH, it just fails immediately.... * Fixed SF bug #3056142: pdl2 fallback to perldl broken on win32 * Fixed SF bug #3042201: t/dumper.t fails mysteriously * Fixed SF bug #3031068: PDL::IO::FlexRaw mapflex memory mapping fails * Fixed SF bug #3011879, "pdl() constructor crashes perl for mixed ref/piddle args" and #3080505, and #3139088. This fix also includes a larger and more complete set of tests. * Fixed segfault in plplot.t with a work-around. * Fixed bug in readenvi.pdl header list value processing and added support for embedded file headers. * Fixed bug in FlexRaw.pm support for headers with Type passed as string. * Fixed imag2d() in PDL::Graphics2D. It no longer calls exit on ESC if run within the pdl2/perldl shell. Also did some clean up of key controls and module mechanics. * Fixed upstream bug in Devel::REPL for MultiLine continuation. Now incomplete q[] and qq[] constructs continue reading until properly closed. See the Known_problems file for details.
