v2.3.2 (2021-12) Charl Linssen <c.linssen@fz-juelich.de>
* Support for pip installing pygsl on Linux systems.
2016-04 Pierre Schnizer <schnizer@user.sourceforge.net>
* Started refurbishment of gsl sf interface generators
* Added sf tests: translated from gsl source
* Added interpolation2d
* Started compiling against gsl-2.1.
* Modified the pygsl error handler:
If PyGSL does not set gsl_error handler to off, the installed error
handler will now store the arguments passed by gsl_error_handler to a
single static variable in the initmodule.
The variable errors.error_safe_state allows retrieving the information
or resetting it.
Normally the status of all functions are converted to python exceptions.
During this process the saved state is reset to zero. This conversion
checks if the to be returned gsl errno is identical to the stored one.
This is not thread safe but should not crash the python interpreter for
functions releasing the GIL (e.g UFUNC's).
2016-03 Pierre Schnizer <schnizer@user.sourceforge.net>
* Added multfit_robust
* Added config option for setup.py. Now it is necessary to run first
"python setup.py config", which will check what the used GSL library
provides. Only the found modules are built then.
2015-09 Pierre Schnizer <schnizer@user.sourceforge.net>
* Ported code base to python 3. Examples and test files expect
a python2 version providing the print function. The C code
should fit to any python2
* Adapted the code to the new NumPy (macro) interface. The code
should work at least with numpy 1.4. Numeric or numarray are not
supported any tested. If you need this code write ti the maintainers
immediatley (called of 5 years ago)
* Made the interface header files compatible with c++. The pygsl
code itself should best be compiled with a C compiler.
2010-02-17 Pierre Schnizer <schnizer@sourceforge.net>
* gsl_function_typemaps.i had a memory leak. Thanks for Nor Pirzkal
for reporting this problem. Added the module callback function_test
helping in debugging the callback function helpers
* interpolation / splines: changed the internal representation
Now the memory managment is handled by python. Further the arrays are
only converted once when the interpolation is used ...
* fixed the order of variables for multifit.wlinear (not affected
real code but was confusing to the user as the names did not
match the meaning).
* gsl_error_typemaps.i: Fixed check of return from PyGSL_ERROR_FLAG
* rng: fixed the rng helper PyGSL_rng_uidA_to_uiA which handles the
rng method multinomial
2009-09-22 Pierre Schnizer <schnizer@sourceforge.net>
* I used to undefine GSL_ERROR macros as well as define
the GSL error function as a macro with 0 arguments to find
usage of gsl_error within the wrapper.
This is uncommented as it created trouble within the code.
* Fixed the tool exporting constant functions. The const module was
updated to the constants of gsl version 1.13
2008-10-25 Pierre Schnizer <schnizer@sourceforge.net>
* Changed the default error handling within PyGSL
Before I installed a gsl_error handler. This handler would then
translate the error numbers to python exceptions. Now this handler
is switched off, as the above approach requires the GIL, which
numpy's ufunc dispose.
Now the error object is set up by the called function before giving
control back to python. Unfortunately the description is lost this
way.
From now on all C code within pygsl must us pygsl_error and PyGSL_ERROR
and associated to get the translater function called.
2008-06-11 Pierre Schnizer <schnizer@sourceforge.net>
* Fixed memory leak in spline / interpolation due to freearg wrongly
named argfree!
2008-02-18 Pierre Schnizer <schnizer@sourceforge.net>
* Found out that I should consider Changelog more seriously
* Changes according to my (lossy) mind
-- Fixed memory leak in rng
-- Moved odeiv.apply to odeiv.apply_vector
-- Readded Function (odeiv.apply)
-- Fixed memory leak in odeiv.apply_vector
* Added support for numpy. On this way I found out, (as required
for 64bit architectures)
- converted all code to use pygsl_array_index_t
(see Include/pygsl/block_helpers.h)
- added internal methods PyGSL_vector_check and PyGSL_array_check.
These can now also handle arrays which have a non native stride.
In this case they will make a contiguous copy
* Added testing.sf and testing.complex module. This now exports the
relevant functions. These all are implemented as Numeric or numpy
ufuncs.
* What did I do the last years? I do not remember ....
2005-06-01 Pierre Schnizer <schnizer@sourceforge.net>
* Fixed an off by one error in the siman module
2005-04-04 Pierre Schnizer <schnizer@sourceforge.net>
* input1 was used as second input in functions
PyGSL_statistics_d_AA, PyGSL_statistics_d_AAd, PyGSL_statistics_d_AAdd
Fixed.
* removed a tangling goto in PyGSL_statistics_d_AA
2005-1-22 Pierre Schnizer <schnizer@users.sourceforge.net>
* Changed the build process. Will read the last selection
for numarray/Numeric if already made. If not, looks which
one it can import, and this it will use. Preference is
Numeric. You can make a selection on the command line using
--array-object=Numeric|numarray.
2005-1 Pierre Schnizer <schnizer@users.sourceforge.net>
* Added switchable debug prints for the C modules
Compile the software with debug=1. Then you can
use pygsl.init.set_debug_level() to switch the
debug prints off and on
2004-12 Pierre Schnizer <schnizer@users.sourceforge.net>
* Added fft module
2004-04 Pierre Schnizer <schnizer@users.sourceforge.net>
* Added support for numarray. Now numarray
can be defined at compile time and numarray
conversion routines are used internally.
2004-03-24 Pierre Schnizer <schnizer@users.sourceforge.net>,
Eric Gurrola, Peter Stoltz
* Moved common functions to one python module to support the
MAC OSX platform
* Rewrite of the statistics module. Moved common functions to
one module. Made them generic and changed the macros to use these
generic functions.
2004-01-09 Leonardo Milano
* Added support for rpm generation
2003-12-27 Pierre Schnizer <schnizer@users.sourceforge.net>
* Reimplementation of the siman module
2003-12-22 Pierre Schnizer <schnizer@users.sourceforge.net>
* Added Monte Carlo support
2003-12-17 Pierre Schnizer <schnizer@users.sourceforge.net>
* error return codes are translated to python exceptions internally.
This changed the API for many functions
2003-12-16 Pierre Schnizer <schnizer@users.sourceforge.net>
* Reimplementation of the rng module supporting internal sampling.
moved to main tree
2003-12-11 Pierre Schnizer <schnizer@users.sourceforge.net>
* Clean up of the diff module:
-- Added checks of the return values of the python callback
-- Simplified the code
-- Thread safety
2003-05-25 Pierre Schnizer <schnizer@users.sourceforge.net>
* Added build support for platforms without a shell
2003-10-5 Pierre Schnizer <schnizer@users.sourceforge.net>
* Added translation of the GSL error number code into the approbriate
python exception.
2003-06-03 Pierre Schnizer <schnizer@users.sourceforge.net>
* combined all helper functions in a library.
* added support for Monte Carlo Integration and Combination.
* added methods to the permutation. Moved the tolist method to a C
implementation.
* Fixed a bug in the error reporting of the float conversion routine.
* added Hankel transform support
* Fixed the spline implementation (was using the interpolation
implementation instead of the spline implementation)
2003-05-18 Achim Gädke <achim.gaedke@physik.tu-darmstadt.de>
* now checked in several changes to create a new release.
activated all available modules, updated README.html
2003-02-09 Pierre Schnizer <schnizer@users.sourceforge.net>
* src/poly, src/callback, src/gslwrap : added these directories, which
provide low level wrapper interface files for swig. These provide low
level interfaces for polynomial, blas, eigen, linalg, integration,
root finding, minimization, multi roots finding, chebychev series
multi dimensional non linear fit
* pygsl/blas.py, pygsl/eigen.py pygsl/linalg.py
These wrappers were written by Fabian Jakobs.
* pygsl/
* Makefile : added. It is only used for developing the swig wrappers.
2003-03-07 Jochen Küpper <jochen@jochen-kuepper.de>
* gsl_Extension.py (gsl_Extension.get_gsl_version): Remove final '+'
from version string. This is used by GSL for cvs versions, these are
now treated analogous to the previous release.
2002-01-27 Jochen Küpper <jochen@jochen-kuepper.de>
* gsl_Extension.py (gsl_Extension.__init__): Set additional macro
NUMERIC to 0 or 1 according to the availablity of NumPy. This
macro can be used as boolean flag in code.
* Local Variables:
* mode: auto-fill
* fill-column: 79
* End:
