(ezalloc_real): New inline function to call calloc.
* gawkapi.h (ezalloc): Add new API macro to allocate memory initialized
to zero.
2017-06-18 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (mbc_char_count): Fix code to correctly traverse
the string. Thanks to Hermann Peifer for the bug report.
* config.guess, config.sub: Update to latest from GNULIB.
* gettext.h: Pull in a few nice changes from GNULIB version.
2017-05-30 Arnold D. Robbins <arnold@skeeve.com>
* NEWS: Mention PROCINFO["argv"].
2017-05-24 Andrew J. Schorr <aschorr@telemetry-investments.com>
* field.c (set_FIELDWIDTHS): Add check to protect against blank
characters after a `:' skip separator.
Fix field number in error message, thanks to a bug report
from Michal Jaegermann.
2017-05-23 Andrew J. Schorr <aschorr@telemetry-investments.com>
* field.c (set_FIELDWIDTHS): Simplify the logic and consistentify
use of UINT_MAX. Make sure that negative value after : is caught.
2017-05-23 Arnold D. Robbins <arnold@skeeve.com>
* field.c (fw_parse_field): Stop upon hitting the end of the
record; this enables correct counting of the number of fields.
(set_FIELDWIDTHS): Add `*' at end as meaning ``all the rest
of the data on the line.'' Allow skip:* as well.
* NEWS: Update information about FIELDWIDTHS.
2017-05-20 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (add_lint): Make ``no effect'' check smarter about
reporting line numbers.
2017-05-01 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (nextc): Fix to change of 2017-04-24 such that
@include works in multibyte locales. Thanks to Hermann
Peifer for the bug report.
2017-04-26 Andrew J. Schorr <aschorr@telemetry-investments.com>
* awkgram.y (make_regnode): Fix bug -- we should not set valref to 1
when creating a node of type Node_regex, since valref is appropriate
only for Node_val nodes. This fixes a bug introduced in commit
687e6594. Also, add an assert to make it clear that this function
supports only Node_regex and Node_dynregex.
* awk.h (NODE): Restore sref to the `val' subportion, since it is not
really needed for Node_regex, now that the bug in make_regnode has
been fixed.
(valref): Restore macro definition.
2017-04-24 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (NODE): Additional cleanups. Removed `aq' and `param_list'
elements from various unions and removed 'nextp' and
`a_opaque' defines. None of these were in use.
Rework the comment for valref, per suggestion from
Andrew Schorr.
2017-04-23 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (nextc): Adjust so that 3.1.x behavior is restored
whereby --source arguments are concatenated. Thanks to
"Neil R. Ormos" <ormos-gnulists17@ormos.org> for the report.
2017-04-21 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (NODE): Put the `val' subportion back the way it
was and move valref (formerly sref) out of the unions
entirely. This was the real problem. Rework the corresponding
commentary.
[valref]: Removed the macro definition.
2017-04-20 Arnold D. Robbins <arnold@skeeve.com>
* configure.ac: Make letter case usage in the various
AC_ARG_ENABLE messages consistent with the rest of configure
output.
(--disable-mpfr): Add this option to make it easier
to check compiles without MPFR. Motivated by:
* awk.h (NODE): Rearrange the layout of the 'val' subportion
of the union to fix alignment problems when compiling without
MPFR. The problem only happened on 64-bit compiles, not
32-bit compiles.
2017-04-16 Arnold D. Robbins <arnold@skeeve.com>
Rename intdiv it intdiv0 and require enabling at configure time.
* awkgram.y (tokentab): Bracket intdiv0 in #ifdef SUPPLY_INTDIV.
(snode): Similar.
* builtin.c (do_intdiv): Bracket in #ifdef SUPPLY_INTDIV.
* mpfr.c (do_mpfr_intdiv): Bracket in #ifdef SUPPLY_INTDIV.
* configure.ac: Add --enable-builtin-intdiv0 option. If enabled,
also revise doc/gawktexi.in.
2017-04-16 Arnold D. Robbins <arnold@skeeve.com>
* builtin.c (do_intdiv): Use DEREF on the arguments.
Thanks to Andrew Schorr for finding the problem.
* mpfr.c (do_mpfr_intdiv): Return -1 if numerator or denominator
are not valid numbers. Unref various bits first.
2017-04-13 Arnold D. Robbins <arnold@skeeve.com>
* awk.h (make_number_node): Simplify.
* mpfr.c (mpg_node): Change parameter name to `flags'.
2017-04-12 Arnold D. Robbins <arnold@skeeve.com>
* mpfr.c (mpg_format_val): Set STRCUR flag when we're done.
Fixes a memory leak. Thanks to valgrind for the report.
* builtin.c (do_dcgettext): Move declaration of reslen to
outside the ifdefs. Thanks to Hermann Peifer for the report.
* gawkapi.c (awk_value_to_node): Initialize ext_ret_val to NULL
to avoid compiler warnings.
2017-04-12 Manuel Collado <m-collado@users.sourceforge.net>
Fix the FPAT bug reported by Ed Morton in the gawk-bug mailing list.
* awk.h (Regexp): Remove the non_empty flag.
* field.c (fpat_parse_field): Restructure the code to reduce complexity
and document the new structure.
* field.c (fpat_parse_field): Further restructuring to avoid
invalid reads as reported by valgrind.
2017-04-10 Andrew J. Schorr <aschorr@telemetry-investments.com>
* awk.h (enum opcodeval): For the avoidance of doubt, specify that
Op_illegal must equal zero.
