PyTables 0.9.1:
This release is mainly a maintenance version. In it, some bugs has been
fixed and a few improvements has been made. One important thing is that
chunk sizes in EArrays has been re-tuned to get much better performance
and compression rations. Besides, it has been tested against the latest
Python 2.4 and all test units seems to pass fine.
PyTables 0.9:
In this release you will find a series of quite exciting new features,
the most important being new indexing capabilities, in-kernel selections,
support for complex datatypes and the possibility to modify values in both
tables and arrays (yeah, finally :).
Support Python 2.4
1.1.1 changes:
numarray-1.1.1 is a bugfix release to numarray-1.1. Notable bugs
fixed include memory leaks in matrixmultiply and comparison ufuncs.
1.1 changes:
I. ENHANCEMENTS
CharArray eval() sped up
Document memmap.py (memory mapping)
Unsigned int type support limited
Add kroenecker product
II. BUGS FIXED / CLOSED
max.reduce of byteswapped array
numeric compatibility byteoffset
matrixmultiply (a,b) leaves b transposed
random_array.randint exceeds boundaries
buffer not aligned on 8 byte boundary (Windows-98 broken)
Object Array repr for >1000 elements
Invalid sequences errors
Segfault in array element deletion
Incorrect handling of overlapping assignments in Numarray
Weirdness with 'new' method
searchsorted bug and fix
randint bug fix patch
a.is_c_array() mixed int/bool results
argsort of string arrays
III. CAUTIONS
1. This release is binary incompatible with numarray-1.0. Writers of
C-extensions which directly reference the byteoffset field of the
PyArrayObject should be aware that the data pointer is now the sum of
byteoffset and the buffer base pointer. All C extensions which use
the numarray C-API must be recompiled. This incompatibility was an
unfortunate consequence of the fix for "numeric compatibility
byteoffset".
* Show base (if not decimal, hexadecimal or non-standard) as subscript
* Use singular instead of abbreviated name for completion
* Fix "Convert result" button
* Use the last operator for leftover stack values
* Fix RPN crash and don't add lonely stack value to itself
* Workaround freeze with message dialog without buttons
Changes:
Another minor adjustment to simplify command to make everything work
just right.
Trap "derivative x" of (negative constant or zero)^x.
Solve "(constant)^y=constant" for y.
Moved all html files and the man page to subdirectory "doc".
Code cleanup.
Improved modulus solving.
Trap "x%0". Simplify "x%inf".
Fix fraction list display of -0.
Change for better simplification.
Fix for division by roots of fractions.
Collection.
Set::Infinite is a Set Theory module for infinite sets.
It works with reals, integers, and objects.
When it is used dates, this module provides schedule
checks (intersections), unions, and infinite recurrences.
python*-pth packages into meta-packages which will install the non-pth
packages. Bump PKGREVISIONs on the non-pth versions to propagate the
thread change, but leave the *-pth versions untouched to not affect
existing installations.
Sync all PYTHON_VERSIONS_AFFECTED lines in package Makefiles.
- bug fix in handling of -pi (previous version changed constant pi)
- bug fix in division of integer vectors with negative coefficients
- for loop can now handle >= 2**32 iterations
- fixed bug which occurred in V 1.50 while parsing certain
parenthized expressions
Changes:
Some more improvement to simplification.
Displayed floating point precision reduced to 12 digits.
Allow typing just "e#" or "pi" on the command line, to give the
values for each.
Changed simplify command to prefer (1/constant)^n instead of 1/(constant^n).
It produces more efficient code and solves a problem.
Improved "code integer" command by allowing integer powers.
Improved eliminate command by trying next equation if solve fails.
"list export" now produces 100% Maxima compatible equations.
Changed "SILENT" compile time define to also remove all debugging code.
Core simplex method and interior-point method routines were
re-implemented and now they use a new, "storage-by-rows" sparse
matrix format (unlike previous versions where linked lists were
used to represent sparse matrices). For details see ChangeLog.
Also a minor bug was fixed in API routine lpx_read_cpxlp.
* Added a new wavelet directory, with 1-dimensional and 2-dimensional
discrete wavelet transforms.
* Added support for LQ and P^T LQ decompositions. To find the QR
decomposition of large systems (M>>N) use the LQ decomposition,
solving the transpose of the original system. This allows more
efficient memory access, and is useful for solving large least-squares
problems.
* Fixed a bug in the SYRK and HERK blas functions gsl_blas_{s,d,c,z}syrk
and gsl_blas_{c,z}herk which caused invalid memory access for non-square
matrices.
* Fixed a bug in gsl_swap_vectors which caused it to return incorrect
results when swapping vectors with different strides.
* Corrected the error estimate for gsl_cheb_eval_n_err to use
evaluation order instead of the approximation order.
* Improved the reliability of the gsl_sf_gamma_inc family of
functions.
* Equal abscissae are now handled gracefully in the cspline and
periodic cspline interpolations.
* Removed potential cancellation error in calculation of uniform
histogram ranges.
* Improved numerical stability of integration for akima and cspline
interpolation.
* Differential equation solvers now handle error codes returned from
user-defined functions.
* Improved error estimates in ode-initval solvers, and provide exact
derivatives on output. Added new semi-implicit ode-initval solver,
gsl_odeiv_step_rk2simp.
* Added missing function definition for gsl_sf_psi_1.
* Fixed the function gsl_sf_expint_Ei_scaled to call
gsl_sf_expint_Ei_scaled_e instead of gsl_sf_expint_Ei_e.
* Added cumulative distribution function for exponential power
distribution.
* The functions gsl_cdf_beta_P and gsl_cdf_beta_Q now return
consistent results of 0 or 1 for out of range values, x<0 and x>1,
rather than 0 for left and right tails simultaneously.
* The Jacobi eigensolvers gsl_eigen_jacobi and gsl_eigen_jacobi_invert
have new implementations from Golub and Van Loan.
* The standard output and standard error streams are now flushed by
the default error handler before the program aborts, in order to
ensure that error messages are properly displayed on some platforms.
post-configure time, even after the switch from buildlink2 to buildlink3.
Also, use SUBST_CLASSES instead of the custom post-configure target,
and take advantage of the fact that the "unwrap" SUBST_CLASS already
does mostly the right thing.
Overview of changes in gcalctool 4.4.22
* Fixed bug #163468. Pressing "(<Del>)" would cause gcalctool to crash.
Overview of changes in gcalctool 4.4.21
* Fixed bug #157277. Entering "(" followed by Clr using the mouse to
click on the buttons, caused a bogus character to be displayed and
the display wasn't cleared.
framework. The list of changes include:
* Modify compiler.mk so that "c" is always prepended to USE_LANGUAGES,
so we no longer need to say it in package Makefiles. Packages
should now append to USE_LANGUAGES instead of setting it.
* Create mk/compiler/f2c.mk which implements another pseudo-compiler
"f2c" that may be used with any C compiler backend, e.g.
PKGSRC_COMPILER= f2c ccache gcc
* Teach the various "real" compiler files, e.g., sunpro.mk, mipspro.mk,
etc., to use f2c if the native Fortran compiler isn't present.
Packages that use Fortran should now simply include the line:
USE_LANGUAGES+= fortran
in the package Makefile.
Changes:
- Some more touch-ups to solve routine.
- Changed uf_repeat() to skip expanding if the expression would be too big.
This allows Mathomatic to work with huge exponents.
- Turned on "preserve_roots" option by default.
- Improved sum and product commands. Allow counting down.
- Improved solve routine and removed display of useless messages.
- Added a fix to the limit command.
- Moved "source.txt" into "README.txt".
- Added code to simplify (inf+a) to (inf) generally.
- Fixed minor bug in calculate command.
- Minor fixes to elim_k().
- Improved limit command.
- Made all recursive functions in the source code static.
Most functions never used globally defined as static.
- Improvement in command argument parsing.
- Added extrema command.
- Improved output of roots command.
- Fixed minor bug caused by "preserve_roots" option.
- Made file "am.htm" valid HTML.
- Simplification improved.

This module generates a variety of random numbers. Capabilities of wide
interest include the generation of:
. uniform numbers between 0 and 1 (or user chosen boundaries)
. random integers between user specified bounds
. random permutations of a list (shuffle a deck of cards)
Changes:
- Many minor improvements made, none of which are worth mentioning by
themselves.
- Fixed all message strings with a variable listed in them.
- Added iteration option to calculate command.
- Trimmed set command of fat. Unnecessary messages removed.
- Removed all occurrences of "usage_flag".
- Usage info is now displayed everytime a command returns with error.
- Allow parsing of hexadecimal constants. Preceed hex numbers with
"0x".
- There may be parsing bugs. Systems using older versions of the GNU
libraries (specifically strtod(3)) will not allow hexadecimal input.
- Added limit command.
- Trapped 0^(negative number). It previously produced junk.
- Allow solve routine to produce infinity as an answer.
- Some commenting and fixing done to solve routine.
Fixed a bug reported by the sourceforge user: cedars where:
ln(exp(6)) == 3 /* WRONG!!! */
incorrectly returned 1. This bug was fixed by Ernest Bowen
The regression test was expanded to cover this issue.
Added minor improvements to hash regression testing of pi().
Fixed "help script" and the calc man page regarding the requirement
of -f to be the last -flag in shell script mode. Further clarified
the meaning and placement of the -f flag.
Moved issues with chi.cal intfile.cal into a "mis-features" section
of the BUGS file. See "help bugs" or the BUGS source file for details.
Added the bug about:
calc 'read ellip; efactor(13*17*19)'
to the BUGS file. See "help bugs" or the BUGS source file for details.
Anyone want to track down and fix this bug?
We might replace the gnumeric-1.2.x pkg eventually. Can't do this now
because the Python plugin isn't built for some reason, so this would
be a regression. (Don't have time to fix this right now.)
