to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
Summary of important user-visible changes for version 3.6:
---------------------------------------------------------
** The PCRE library is now required to build Octave. If a pre-compiled
package does not exist for your system, you can find PCRE sources
at http://www.pcre.org
** The ARPACK library is no longer distributed with Octave.
If you need the eigs or svds functions you must provide an
external ARPACK through a package manager or by compiling it
yourself. If a pre-compiled package does not exist for your system,
you can find the current ARPACK sources at
http://forge.scilab.org/index.php/p/arpack-ng
** Many of Octave's binary operators (.*, .^, +, -, ...) now perform
automatic broadcasting for array operations which allows you to use
operator notation instead of calling bsxfun or expanding arrays (and
unnecessarily wasting memory) with repmat or similar idioms. For
example, to scale the columns of a matrix by the elements of a row
vector, you may now write
rv .* M
In this expression, the number of elements of rv must match the
number of columns of M. The following operators are affected:
plus + .+
minus - .-
times .*
rdivide ./
ldivide .\
power .^ .**
lt <
le <=
eq ==
gt >
ge >=
ne != ~=
and &
or |
atan2
hypot
max
min
mod
rem
xor
additionally, since the A op= B assignment operators are equivalent
to A = A op B, the following operators are also affected:
+= -= .+= .-= .*= ./= .\= .^= .**= &= |=
See the "Broadcasting" section in the new "Vectorization and Faster
Code Execution" chapter of the manual for more details.
** Octave now features a profiler, thanks to the work of Daniel Kraft
under the Google Summer of Code mentorship program. The manual has
been updated to reflect this addition. The new user-visible
functions are profile, profshow, and profexplore.
** Overhaul of statistical distribution functions
Functions now return "single" outputs for inputs of class "single".
75% reduction in memory usage through use of logical indexing.
Random sample functions now use the same syntax as rand and accept
a comma separated list of dimensions or a dimension vector.
Functions have been made Matlab-compatible with regard to special
cases (probability on boundaries, probabilities for values outside
distribution, etc.). This may cause subtle changes to existing
scripts.
negative binomial function has been extended to real, non-integer
inputs. The discrete_inv function now returns v(1) for 0 instead of
NaN. The nbincdf function has been recoded to use a closed form
solution with betainc.
** strread, textscan, and textread have been completely revamped.
They now support nearly all Matlab functionality including:
* Matlab-compatible whitespace and delimiter defaults
* Matlab-compatible options: 'whitespace', treatasempty', format
string repeat count, user-specified comment style, uneven-length
output arrays, %n and %u conversion specifiers (provisionally)
** All .m string functions have been modified for better performance or
greater Matlab compatibility. Performance gains of 15X-30X have
been demonstrated. Operations on cell array of strings no longer pay
quite as high a penalty as those on 2-D character arrays.
deblank: Now requires character or cellstr input.
strtrim: Now requires character or cellstr input.
No longer trims nulls ("\0") from string for Matlab
compatibility.
strmatch: Follows documentation precisely and ignores trailing spaces
in pattern and in string. Note that this is documented
Matlab behavior but the implementation apparently does
not always follow it.
substr: Now possible to specify a negative LEN option which
extracts to within LEN of the end of the string.
strtok: Now accepts cellstr input.
base2dec, bin2dec, hex2dec:
Now accept cellstr inputs.
dec2base, dec2bin, dec2hex:
Now accept cellstr inputs.
index, rindex:
Now accept 2-D character array input.
strsplit: Now accepts 2-D character array input.
** Geometry functions derived from Qhull (convhull, delaunay, voronoi)
have been revamped. The options passed to the underlying qhull
command have been changed for better results or for Matlab
compatibility.
convhull: Default options are "Qt" for 2D, 3D, 4D inputs
Default options are "Qt Qx" for 5D and higher
delaunay: Default options are "Qt Qbb Qc Qz" for 2D and 3D inputs
Default options are "Qt Qbb Qc Qx" for 4D and higher
voronoi: No default arguments
** Date/Time functions updated. Millisecond support with FFF format
string now supported.
datestr: Numerical formats 21, 22, 29 changed to match Matlab.
Now accepts cellstr input.
** The following warning IDs have been removed:
Octave:associativity-change
Octave:complex-cmp-ops
Octave:empty-list-elements
Octave:fortran-indexing
Octave:precedence-change
** The warning ID Octave:string-concat has been renamed to
Octave:mixed-string-concat.
** Octave now includes the following Matlab-compatible preference
functions:
addpref getpref ispref rmpref setpref
** The following Matlab-compatible handle graphics functions have been
added:
guidata uipanel uitoolbar
guihandles uipushtool uiwait
uicontextmenu uiresume waitfor
uicontrol uitoggletool
The uiXXX functions above are experimental.
Except for uiwait and uiresume, the uiXXX functions are not
supported with the FLTK+OpenGL graphics toolkit.
The gnuplot graphics toolkit does not support any of the uiXXX
functions nor the waitfor function.
** New keyword parfor (parallel for loop) is now recognized as a valid
keyword. Implementation, however, is still mapped to an ordinary
for loop.
** Other new functions added in 3.6.0:
bicg nthargout usejava
is_dq_string narginchk waitbar
is_sq_string python zscore
is_function_handle register_graphics_toolkit
loaded_graphics_toolkits recycle
** Deprecated functions.
The following functions were deprecated in Octave 3.2 and have been
removed from Octave 3.6.
create_set spcholinv splu
dmult spcumprod spmax
iscommand spcumsum spmin
israwcommand spdet spprod
lchol spdiag spqr
loadimage spfind spsum
mark_as_command sphcat spsumsq
mark_as_rawcommand spinv spvcat
spatan2 spkron str2mat
spchol splchol unmark_command
spchol2inv split unmark_rawcommand
The following functions have been deprecated in Octave 3.6 and will
be removed from Octave 3.10 (or whatever version is the second major
release after 3.6):
cut is_duplicate_entry
cor polyderiv
corrcoef shell_cmd
__error_text__ studentize
error_text sylvester_matrix
** The following functions have been modified for Matlab compatibility:
randperm
* Stop to treat NetBSD's sed as GNU sed, not full compatible.
* Then, no need to reset TOOLS_PLATFORM.gsed for NetBSD if USE_TOOLS+=gsed and
real GNU sed is required.
* In addition, convert simple USE_TOOLS+=gsed to conditionally, without NetBSD.
* convert {BUILD_,}DEPENDS+=gsed to USE_TOOLS, all tools from gsed are real gsed.
This makes the package build and work at least in NetBSD on some platforms.
Summary of important user-visible changes for version 3.4.3:
-----------------------------------------------------------
** Octave 3.4.3 is a bug fixing release.
Summary of important user-visible changes for version 3.4.2:
-----------------------------------------------------------
** Octave 3.2.4 fixes some minor installation problems that affected
version 3.4.1.
Summary of important user-visible changes for version 3.4.1:
-----------------------------------------------------------
** Octave 3.4.1 is primarily a bug fixing release.
** IMPORTANT note about binary incompatibility in this release:
Binary compatibility for all 3.4.x releases was originally planned,
but this is impossible for the 3.4.1 release due to a bug in the way
shared libraries were built in Octave 3.4.0. Because of this bug,
.oct files built for Octave 3.4.0 must be recompiled before they
will work with Octave 3.4.1.
Given that there would be binary incompatibilities with shared
libraries going from Octave 3.4.0 to 3.4.1, the following
incompatible changes were also made in this release:
* The Perl Compatible Regular Expression (PCRE) library is now
required to build Octave.
* Octave's libraries and .oct files are now installed in
subdirectories of $libdir instead of $libexecdir.
Any future Octave 3.4.x release versions should remain binary
compatible with Octave 3.4.1 as proper library versioning is now
being used as recommended by the libtool manual.
** The following functions have been deprecated in Octave 3.4.1 and will
be removed from Octave 3.8 (or whatever version is the second major
release after 3.4):
cquad is_duplicate_entry perror strerror
** The following functions are new in 3.4.1:
colstyle gmres iscolumn isrow mgorth nproc rectangle
** The get_forge_pkg function is now private.
** The rectangle_lw, rectangle_sw, triangle_lw, and triangle_sw
functions are now private.
** The logistic_regression_derivatives and logistic_regression_likelihood
functions are now private.
** ChangeLog files in the Octave sources are no longer maintained
by hand. Instead, there is a single ChangeLog file generated from
the Mercurial version control commit messages. Older ChangeLog
information can be found in the etc/OLD-ChangeLogs directory in the
source distribution.
Summary of important user-visible changes for version 3.4:
---------------------------------------------------------
** BLAS and LAPACK libraries are now required to build Octave. The
subset of the reference BLAS and LAPACK libraries has been removed
from the Octave sources.
** The `lookup' function was extended to be more useful for
general-purpose binary searching. Using this improvement, the
ismember function was rewritten for significantly better
performance.
** Real, integer and logical matrices, when used in indexing, will now
cache the internal index_vector value (zero-based indices) when
successfully used as indices, eliminating the conversion penalty for
subsequent indexing by the same matrix. In particular, this means it
is no longer needed to avoid repeated indexing by logical arrays
using find for performance reasons.
** Logical matrices are now treated more efficiently when used as
indices. Octave will keep the index as a logical mask unless the
ratio of true elements is small enough, using a specialized
code. Previously, all logical matrices were always first converted
to index vectors. This results in savings in both memory and
computing time.
** The `sub2ind' and `ind2sub' functions were reimplemented as compiled
functions for better performance. These functions are now faster,
can deliver more economized results for ranges, and can reuse the
index cache mechanism described in previous paragraph.
** The built-in function equivalents to associative operators (`plus',
`times', `mtimes', `and', and `or') have been extended to accept
multiple arguments. This is especially useful for summing
(multiplying, etc.) lists of objects (of possibly distinct types):
matrix_sum = plus (matrix_list{:});
** An FTP object type based on libcurl has been implemented. These
objects allow ftp connections, downloads and uploads to be
managed. For example,
fp = ftp ("ftp.octave.org);
cd (fp, "gnu/octave");
mget (fp, "octave-3.2.3.tar.bz2");
close (fp);
** The default behavior of `assert (observed, expected)' has been
relaxed to employ less strict checking that does not require the
internals of the values to match. This avoids previously valid
tests from breaking due to new internal classes introduced in future
Octave versions.
For instance, all of these assertions were true in Octave 3.0.x
but false in 3.2.x due to new optimizations and improvements:
assert (2*linspace (1, 5, 5), 2*(1:5))
assert (zeros (0, 0), [])
assert (2*ones (1, 5), (2) (ones (1,5)))
** The behavior of library functions `ismatrix', `issquare', and
`issymmetric' has been changed for better consistency.
* The `ismatrix' function now returns true for all numeric,
logical and character 2-D or N-D matrices. Previously, `ismatrix'
returned false if the first or second dimension was zero.
Hence, `ismatrix ([])' was false,
while `ismatrix (zeros (1,2,0))' was true.
* The `issquare' function now returns a logical scalar, and is
equivalent to the expression
ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x)
The dimension is no longer returned. As a result, `issquare ([])'
now yields true.
* The `issymmetric' function now checks for symmetry instead of
Hermitianness. For the latter, ishermitian was created. Also,
logical scalar is returned rather than the dimension, so
`issymmetric ([])' is now true.
** Function handles are now aware of overloaded functions. If a
function is overloaded, the handle determines at the time of its
reference which function to call. A non-overloaded version does not
need to exist.
** Overloading functions for built-in classes (double, int8, cell,
etc.) is now compatible with Matlab.
** Function handles can now be compared with the == and != operators,
as well as the `isequal' function.
** Performance of concatenation (using []) and the functions `cat',
`horzcat', and `vertcat' has been improved for multidimensional
arrays.
** The operation-assignment operators +=, -=, *= and /= now behave more
efficiently in certain cases. For instance, if M is a matrix and S a
scalar, then the statement
M += S;
will operate on M's data in-place if it is not shared by another
variable, usually increasing both time and memory efficiency.
Only selected common combinations are affected, namely:
matrix += matrix
matrix -= matrix
matrix .*= matrix
matrix ./= matrix
matrix += scalar
matrix -= scalar
matrix *= scalar
matrix /= scalar
logical matrix |= logical matrix
logical matrix &= logical matrix
where matrix and scalar belong to the same class. The left-hand
side must be a simple variable reference.
Moreover, when unary operators occur in expressions, Octave will
also try to do the operation in-place if it's argument is a
temporary expresssion.
** The effect of comparison operators (<, >, <=, and >=) applied to
complex numbers has changed to be consistent with the strict
ordering defined by the `max', `min', and `sort' functions. More
specifically, complex numbers are compared by lexicographical
comparison of the pairs `[abs(z), arg(z)]'. Previously, only real
parts were compared; this can be trivially achieved by wrapping the
operands in real().
** The automatic simplification of complex computation results has
changed. Octave will now simplify any complex number with a zero
imaginary part or any complex matrix with all elements having zero
imaginary part to a real value. Previously, this was done only for
positive zeros. Note that the behavior of the complex function is
unchanged and it still produces a complex value even if the
imaginary part is zero.
** As a side effect of code refactoring in liboctave, the binary
logical operations are now more easily amenable to compiler
optimizations and are thus significantly faster.
** Octave now allows user-defined `subsasgn' methods to optimize out
redundant copies. For more information, see the manual.
** More efficient matrix division handling. Octave is now able to
handle the expressions
M' \ V
M.' \ V
V / M
(M is a matrix and V is a vector) more efficiently in certain cases.
In particular, if M is triangular, all three expressions will be
handled by a single call to xTRTRS (from LAPACK), with appropriate
flags. Previously, all three expressions required a physical
transpose of M.
** More efficient handling of certain mixed real-complex matrix
operations. For instance, if RM is a real matrix and CM a complex
matrix,
RM * CM
can now be evaluated either as
complex (RM * real (CM), RM * imag (CM))
or as
complex (RM) * CM,
depending on the dimensions. The first form requires more
temporaries and copying, but halves the FLOP count, which normally
brings better performance if RM has enough rows. Previously, the
second form was always used.
Matrix division is similarly affected.
** More efficient handling of triangular matrix factors returned from
factorizations. The functions for computing QR, LU and Cholesky
factorizations will now automatically return the triangular matrix
factors with proper internal matrix_type set, so that it won't need
to be computed when the matrix is used for division.
** The built-in `sum' function now handles the non-native summation
(i.e., double precision sum of single or integer inputs) more
efficiently, avoiding a temporary conversion of the whole input
array to doubles. Further, `sum' can now accept an extra option
argument, using a compensated summation algorithm rather than a
straightforward sum, which significantly improves precision if lots
of cancellation occurs in the summation.
** The built-in `bsxfun' function now uses optimized code for certain
cases where built-in operator handles are passed in. Namely, the
optimizations concern the operators `plus', `minus', `times',
`ldivide', `rdivide', `power', `and', `or' (for logical arrays),
the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the
functions `min' and `max'. Optimizations only apply when both
operands are of the same built-in class. Mixed real/complex and
single/double operations will first convert both operands to a
common type.
** The `strfind' and `strrep' functions now have compiled
implementations, facilitating significantly more efficient searching
and replacing in strings, especially with longer patterns. The code
of `strcat' has been vectorized and is now much more efficient when
many strings are concatenated. The `strcmpi' and `strncmpi'
functions are now built-in functions, providing better performance.
** Matlab-style ignoring input and output function arguments using
tilde (~) is now supported. Ignored output arguments may be
detected from a function using the built-in function `isargout'.
For more details, consult the manual.
** The list datatype, deprecated since the introduction of cells, has
been removed.
** The accumarray function has been optimized and is now significantly
faster in certain important cases.
** The behavior of isreal and isnumeric functions was changed to be more
Matlab-compatible.
** The integer math & conversion warnings (Octave:int-convert-nan,
Octave:int-convert-non-int-val, Octave:int-convert-overflow,
Octave:int-math-overflow) have been removed.
** rem and mod are now built-in functions. They also handle integer
types efficiently using integer arithmetic.
** Sparse indexing and indexed assignment has been mostly rewritten.
Since Octave uses compressed column storage for sparse matrices,
major attention is devoted to operations manipulating whole columns.
Such operations are now significantly faster, as well as some other
important cases.
Further, it is now possible to pre-allocate a sparse matrix and
subsequently fill it by assignments, provided they meet certain
conditions. For more information, consult the `spalloc' function,
which is no longer a mere dummy. Consequently, nzmax and nnz are no
longer always equal in Octave. Octave may also produce a matrix
with nnz < nzmax as a result of other operations, so you should
consistently use nnz unless you really want to use nzmax (i.e. the
space allocated for nonzero elements).
Sparse concatenation is also affected, and concatenating sparse
matrices, especially larger collections, is now significantly more
efficient. This applies to both the [] operator and the
cat/vertcat/horzcat functions.
** It is now possible to optionally employ the xGESDD LAPACK drivers
for computing the singular value decomposition using svd(), instead
of the default xGESVD, using the configuration pseudo-variable
svd_driver. The xGESDD driver can be up to 6x times faster when
singular vectors are requested, but is reported to be somewhat less
robust on highly ill-conditioned matrices.
** Configuration pseudo-variables, such as page_screen_output or
confirm_recursive_rmdir (or the above mentioned svd_driver), now
accept a "local" option as second argument, requesting the change
to be undone when the current function returns:
function [status, msg] = rm_rf (dir)
confirm_recursive_rmdir (false, "local");
[status, msg] = rmdir (dir, "s");
...
endfunction
Upon return, confirm_recursive_rmdir will be restored to the value
it had on entry to the function, even if there were subsequent
changes to the variable in function rm_rf or any of the functions
it calls.
** pkg now accepts a -forge option for downloading and installing
packages from Octave Forge automatically. For example,
pkg install -forge general
will automatically download the latest release of the general
package and attempt to install it. No automatic resolving of
dependencies is provided. Further,
pkg list -forge
can be used to list all available packages.
** The internal data representation of structs has been completely
rewritten to make certain optimizations feasible. The field data
can now be shared between structs with equal keys but different
dimensions or values, making operations that preserve the fields
faster. Economized storage is now used for scalar structs (just
like most other scalars), making their usage more
memory-efficient. Certain array-like operations on structs
(concatenation, uniform cellfun, num2cell) have gained a
significant speed-up. Additionally, the octave_scalar_map class
now provides a simpler interface to work with scalar structs within
a C++ DLD function.
** Two new formats are available for displaying numbers:
format short eng
format long eng
Both display numbers in engineering notation, i.e., mantissa +
exponent where the exponent is a multiple of 3.
** The following functions are new in Octave 3.4:
accumdim erfcx nfields pqpnonneg uigetdir
bitpack fileread nth_element quadcc uigetfile
bitunpack fminbnd onCleanup randi uiputfile
blkmm fskipl pbaspect repelems uimenu
cbrt ifelse pie3 reset whitebg
curl ishermitian powerset rsf2csf
chop isindex ppder saveas
daspect luupdate ppint strread
divergence merge ppjumps textread
** Using the image function to view images with external programs such
as display, xv, and xloadimage is no longer supported. The
image_viewer function has also been removed.
** The behavior of struct assignments to non-struct values has been
changed. Previously, it was possible to overwrite an arbitrary
value:
a = 1;
a.x = 2;
This is no longer possible unless a is an empty matrix or cell
array.
** The dlmread function has been extended to allow specifying a custom
value for empty fields.
** The dlmread and dlmwrite functions have been modified to accept
file IDs (as returned by fopen) in addition to file names.
** Octave can now optimize away the interpreter overhead of an
anonymous function handle, if the function simply calls another
function or handle with some of its parameters bound to certain
values. Example:
f = @(x) sum (x, 1);
When f is called, the call is forwarded to @sum with the constant 1
appended, and the anonymous function call does not occur on the
call stack.
** Deprecated functions.

as executables rather than loadable modules
This might cause that the pkg doesn't build on as many platforms as
it did before, but it has a chance to work now.
bump PKGREV
Shared directories can now be created independently by the pacakges
needing them and will be removed automatically by pkg_delete when empty.
Packages needing empty directories can use the @pkgdir command in PLIST.
Discussed and ok'd in thread starting at

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
