2004-07-10 Brian Gough <bjg@network-theory.co.uk>
* error.c (gsl_error): flush stdout/stderr before aborting (needed
to get a useful error message on some platforms)
2003-06-17 Brian Gough <bjg@network-theory.co.uk>
* warn.c: removed, the functions are not used
Sat Apr 27 21:27:32 2002 Brian Gough <bjg@network-theory.co.uk>
* error.c (gsl_error): added an explanatory message in the default
error handler before aborting
Tue Jun 12 11:52:23 2001 Brian Gough <bjg@network-theory.co.uk>
* gsl_errno.h (GSL_STATUS_UPDATE): added macro for updating
status value multiple times
Fri Apr 27 18:18:59 2001 Brian Gough <bjg@network-theory.co.uk>
* gsl_errno.h (GSL_ERROR_NULL): added macro which returns NULL,
for out of memory conditions
Mon Jan 22 16:01:55 2001 Brian Gough <bjg@network-theory.co.uk>
* gsl_errno.h: added EOF for end of file
Sat Aug 26 19:26:59 2000 Brian Gough <bjg@network-theory.co.uk>
* gsl_errno.h: added error codes ETOLF, ETOLX, ETOLG for
unattainable tolerances in (F,X,G) in multimin MINPACK LM
algorithm.
Fri May 5 11:20:10 2000 Brian Gough <bjg@network-theory.co.uk>
* split gsl_test code out into separate test/ directory
Sun Nov 28 17:17:03 1999 Brian Gough <bjg@network-theory.co.uk>
* gsl_errno.h: added GSL_ENOPROG and GSL_ENOPROGJ to handle error
conditions from minpack hybrid algorithms (INFO=5,4 in the
original code)
Thu Oct 28 14:41:31 1999 Brian Gough <bjg@network-theory.co.uk>
* gsl_test.h: changed variable name in prototype for clarity
Thu Oct 7 11:46:53 1999 Brian Gough <bjg@network-theory.co.uk>
* test_results.c (gsl_test_str): changed #if __STDC__ to #ifdef
__STDC__ so the code will compile with compilers that define
__STDC__ to 0 meaning STDC+extensions.
Sun Jul 11 21:48:25 1999 Brian Gough <bjg@network-theory.co.uk>
* test_errnos.c (main): added GSL_ECACHE to handle internal cache
structures which grow and can hit a limit
Sun Mar 7 17:00:08 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
* gsl_errno.h, test_errnos.c, strerror.c: added GSL_EDIVERGE for
divergent integrals and series
Sat Feb 20 12:14:47 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
* test_errnos.c (main): added the new error codes to the tests
* gsl_errno.h: moved all the error codes into a single enum
instead of having a separate enum for GSL_SUCCESS and GSL_FAILURE
Fri Feb 19 15:56:15 1999 Brian Gough <bjg@netsci.freeserve.co.uk>
* gsl_errno.h, strerror.c: added GSL_CONTINUE as an error code
indicating that an iteration process has not converged and should
be continued for more iterations.
Tue Nov 17 17:11:31 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_test.h: removed #include <config.h> which should not be
present in installed header files
Tue Nov 10 15:55:56 1998 Brian Gough <bjg@vvv.lanl.gov>
* test_results.c (gsl_test_abs), gsl_test.h: added gsl_test_abs
for absolute errors, like gsl_test_rel for relative errors
Fri Oct 23 12:51:01 1998 Brian Gough <bjg@vvv.lanl.gov>
* test_results.c (gsl_test_rel): print a shorter "observed vs
expected" message if the description is 45 characters or longer
Mon Jun 1 11:02:04 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h: added GSL_EUNSUP for errors caused by a hardware
feature which is not supported on a particular platform
* renamed test.c to test_results.c to avoid confusion when debugging
other test programs called test.c
Sat May 30 16:11:34 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h: add GSL_ESING for errors caused by singularities
or other bad function behavior
Fri May 29 14:41:19 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h: added GSL_EBADLEN to signify bad lengths of
matrices or vectors (e.g. non-conformant sizes in a matrix or
vector multiplication)
Wed May 27 18:15:34 1998 Brian Gough <bjg@vvv.lanl.gov>
* test.c (gsl_test_str): changed things so that the strings aren't
printed unless the string equality test fails (usually they were
too long)
Mon May 18 17:58:20 1998 Brian Gough <bjg@vvv.lanl.gov>
* test.c (gsl_test_rel): added a test for numerical quantities,
given a result, an expected result and an allowable relative
error.
(gsl_test_int): added a test for comparing integers
Sun May 10 16:03:12 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h: added GSL_EROUND for roundoff errors
Fri May 8 18:50:13 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h: changed GSL_ETIMEOUT to GSL_EMAXITER to describe
the error that occurs when a specified number of iterations is
exceeded.
Sun Apr 19 19:14:05 1998 Brian Gough <bjg@vvv.lanl.gov>
* strerror.c (gsl_strerror): added an strerror function for making
readable descriptions of the error number
Wed Apr 15 21:59:57 1998 Brian Gough <bjg@vvv.lanl.gov>
* added a stream handler, for the error stream
* completely reorganized the files, but the functions are
relatively unchanged
Wed Apr 8 13:55:48 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h (GSL_ERROR_RETURN_NOTHING): added an error macro
suitable for void functions
Mon Apr 6 14:10:48 1998 Brian Gough <bjg@vvv.lanl.gov>
* gsl_errno.h: use enum instead of #define for symbolic constants,
so that they can be seen in the debugger
Sun Apr 5 19:49:17 1998 Brian Gough <bjg@vvv.lanl.gov>
* err/errno.c (gsl_error): now takes gsl_errno as an argument
(this is useful for doing conditional breakpoints)
