Moved calc version definition from version.c to version.h.
Added CALC2_COMPAT, that when defined attempts to maintain calc
version 2 compatibility. When MAJOR_VER <= 2, CALC2_COMPAT is
defined. This is anticipation for a future calc version 3 code.
Updated COPYING file to indicate that these files are now
covered under "The Unlicense" (see https://unlicense.org):
sha1.c
sha1.h
cal/dotest.cal
cal/screen.cal
Updated help/credit to match the above changes to COPYING.
Updated CONTRIB-CODE and calc.man to refer to using GitHub pull requests
for contributing to calc (instead of using Email).
Updated BUGS and calc.man to refer to using GitHub issues
for reporting calc bugs (instead of using Email).
Updated QUESTIONS and calc.man to refer to using GitHub issues
for asking calc questions (instead of using Email).
Fixed Makefile.local command example to refer to overriding the
Makefile variable DEBUG (instead of CDEBUG).
Fixed all make chk ASAN warnings under macOS 13.2.1 when calc is compiled
with the following uncommented lines in Makefile.local:
DEBUG:= -O0 -g
CFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
LDFLAGS+= -fsanitize=address -fno-omit-frame-pointer -fsanitize=undefined
CALC_ENV+= ASAN_OPTIONS=detect_stack_use_after_return=1
Improved how pointers to functions are declared for the builtins
array in func.c to avoid function declarations without a prototype
that is now deprecated in C.
Improved how pointers to functions are declared for the opcodes
array in opcodes.c to avoid function declarations without a prototype
Replaced use of egrep with grep -E in Makefiles.
Fixed cases where variables were set but not used in symbol.c, calc.c,
and the main function in func.c as used by funclist.c.
Added rule name to "DO NOT EDIT -- generated by the Makefile" lines
in constructed files.
Test if <sys/vfs.h> exists and set HAVE_SYS_VFS_H accordingly
in have_sys_vfs.h. Added HAVE_SYS_VFS_H to allow one to force
this value.
Test if <sys/param.h> exists and set HAVE_SYS_PARAM_H accordingly
in have_sys_param.h. Added HAVE_SYS_PARAM_H to allow one to force
this value.
Test if <sys/mount.h> exists and set HAVE_SYS_MOUNT_H accordingly
in have_sys_mount.h. Added HAVE_SYS_MOUNT_H to allow one to force
this value.
Test if the system as the statfs() system call and set HAVE_STATFS
accordingly in have_statfs.h. Added HAVE_STATFS to allow one
to force this value.
The pseudo_seed() function will also try to call statfs() if
possible and permitted by the HAVE_STATFS value.
Added swap_HALFs(dest, src, len) function to byteswap.c.
Calc can now handle Big Engian file position sizes that are a
multiple of BASEB bits in length. Before handle Big Engian file
positions could only be 32 and 64 bits in length. This will allow,
for example, a Big Engian file position size of 128 (assuming that
128/BASEB is is an integer).
The constants:
9, 9/10, 10/9, 24, 360, 400
are used by func.c only, so there were moved
from {q,z}math.{c,h} to func.c.
The constants:
3, 4
are used by zrandom.c only, so there were moved
from {q,z}math.{c,h} to zrandom.c.
Improved the way that internal pre-defined constants are managed.
Removed unused internal pre-defined constants. Added code to
prevent an internal pre-defined constant (that was never
allocated) from being freed.
Added several conversion functions:
Added builtin functions to convert between degrees and
degrees, minutes and seconds under the config("mod")
round rules:
d2dms(degs, d, m, s [,rnd]) - given degs, compute d, m, s
d2dm(degs, d, m [,rnd]) - given degs, compute d, m
See help/d2dms and help/d2dm.
Example:
; print d2dms(360.321,deg=,min=,sec=), deg, min, sec;
0.321 0 19 15.6
; print d2dm(360.321,deg=,min=), deg, min;
0.321 0 19.26
Added builtin functions to convert between gradians and
gradians, minutes and seconds under the config("mod")
round rules:
g2gms(grads, g, m, s [,rnd]) - given grads, compute g, m, s
g2gm(grads, g, m [,rnd]) - given grads, compute g, m
See help/g2gms and help/g2gm.
Example:
; print g2gms(400.321,grad=,min=,sec=), grad, min, sec;
0.321 0 19 15.6
; print g2gm(400.321,grad=,min=), grad, min;
0.321 0 19.26
Added builtin functions to convert between hours and
hours, minutes and seconds under the config("mod")
round rules:
h2hms(hours, h, m, s [,rnd]) - given hours, compute h, m, s
h2hm(hours, h, m [,rnd]) - given hours, compute h, m
See help/h2hms and help/h2hm.
Example:
; print h2hms(24.321,hour=,min=,sec=), hour, min, sec;
0.321 0 19 15.6
; print h2hm(24.321,hour=,min=), hour, min;
0.321 0 19.26
In addtion:
Renumbered regression tests 3408 thru 3437, to 9102 thru 9131.
Updated Added hms.cal resource file to use h2hms() builtin.
Updated Added dms.cal resource file to use d2dms() builtin.
Fix minor typo in help/mod SYNOPSIS.
Fix minor typo in help/quo SYNOPSIS.
Added a few more examples to help/strcmp.
Similar to scientific mode, engineering mode also displays numbers in
base 10 exponential notation, with the difference that exponents are
always multiples of 3, to facilitate the interpretation in terms of
SI prefixes.
The mode is activated in config thru "engineering" or "eng. For base
and base2, it uses the special value 1000.
Added notes to help/unexpected about:
display() will limit the number of digits printed after decimal point
%d will format after the decimal point for non-integer numeric values
%x will format as fractions for non-integer numeric values
fprintf(fd, "%d\n", huge_value) may need fflush(fd) to finish
Fixed Makefile dependencies for the args.h rule.
Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
Sort lists of standard tool Makefile variables and remove duplicates.
Declare the SHELL at the top of Makefiles.
Fixed the depend rule in the custom Makefile.
Improved the messages produced by the depend in the Makefiles.
Changed the UNUSED define in have_unused.h to be a macro with
a parameter. Changed all use of UNUSED in *.c to be UNUSED(x).
Removed need for HAVE_UNUSED in building the have_unused.h file.
CCBAN is given to ${CC} in order to control if banned.h is in effect.
The banned.h attempts to ban the use of certain dangerous functions
that, if improperly used, could compromise the computational integrity
if calculations.
In the case of calc, we are motivated in part by the desire for calc
to correctly calculate: even during extremely long calculations.
If UNBAN is NOT defined, then calling certain functions
will result in a call to a non-existent function (link error).
While we do NOT encourage defining UNBAN, there may be
a system / compiler environment where re-defining a
function may lead to a fatal compiler complication.
If that happens, consider compiling as:
make clobber all chk CCBAN=-DUNBAN
as see if this is a work-a-round.
If YOU discover a need for the -DUNBAN work-a-round, PLEASE tell us!
Please send us a bug report. See the file:
BUGS
or the URL:
http://www.isthe.com/chongo/tech/comp/calc/calc-bugrept.html
for how to send us such a bug report.
Added the building of have_ban_pragma.h, which will determine
if "#pragma GCC poison func_name" is supported. If it is not,
or of HAVE_PRAGMA_GCC_POSION=-DHAVE_NO_PRAGMA_GCC_POSION, then
banned.h will have no effect.
Fixed building of the have_getpgid.h file.
Fixed building of the have_getprid.h file.
Fixed building of the have_getsid.h file.
Fixed building of the have_gettime.h file.
Fixed building of the have_strdup.h file.
Fixed building of the have_ustat.h file.
Fixed building of the have_rusage.h file.
Added HAVE_NO_STRLCPY to control if we want to test if
the system has a strlcpy() function. This in turn produces
the have_strlcpy.h file wherein the symbol HAVE_STRLCPY will
be defined, or not depending if the system comes with a
strlcpy() function.
If the system does not have a strlcpy() function, we
compile our own strlcpy() function. See strl.c for details.
Added HAVE_NO_STRLCAT to control if we want to test if
the system has a strlcat() function. This in turn produces
the have_strlcat.h file wherein the symbol HAVE_STRLCAT will
be defined, or not depending if the system comes with a
strlcat() function.
If the system does not have a strlcat() function, we
compile our own strlcat() function. See strl.c for details.
Fixed places were <string.h>, using #ifdef HAVE_STRING_H
for legacy systems that do not have that include file.
Added ${H} Makefile symbol to control the announcement
of forming and having formed hsrc related files. By default
H=@ (announce hsrc file formation) vs. H=@: to silence hsrc
related file formation.
Explicitly turn off quiet mode (set Makefile variable ${Q} to
be empty) when building rpms.
Improved and fixed the hsrc build process.
Forming rpms is performed in verbose mode to assist debugging
to the rpm build process.
Compile custom code, if needed, after main code is compiled.
This code %g is preliminary.
Fixed some code style issues to match the current code style.
Added regression tests and help file updates to printf and strprintf.
Fixed use of magic number -4: using -P instead.
Noted two problem areas with XXX comments in qio.c:
1) need a qprintfg function
2) re-write to not modify conf->outdigits
Some folks might think: “you still use RCS”?!? And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)
Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.
RCS served us well. But now it is time to move on. And so we are
switching to git.
Calc releases produce a lot of file changes. In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
