 +
 +2017-04-21         Arnold D. Robbins     <address@hidden>
 +
 +      * awk.h (NODE): Put the `val' subportion back the way it
 +      was and move valref (formerly sref) out of the unions

 +      commentary.
 +      [valref]: Removed the macro definition.
 +
 +2017-04-20         Arnold D. Robbins     <address@hidden>
 +
 +      * 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     <address@hidden>
 +
 +      * 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.
 +
 +2017-04-12         Arnold D. Robbins     <address@hidden>
 +
 +      * 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.
 +
 +2017-04-12         Manuel Collado        <address@hidden>
 +
 +      Fix the FPAT bug reported by Ed Morton in the gawk-bug mailing list.

 +      * field.c (set_FIELDWIDTHS): Set use_chars to awk_true, since its
 +      type is awk_bool_t.

 +
 +      * symbol.c (free_bc_mempool): Change `first' from int to bool.

 +      (struct context): Use INSTRUCTION_POOL.
 +      * array.c (assoc_list): Reorg the code a bit to make sure
 +      to alway free the INSTRUCTIONs allocated for calling a
 +      user-supplied sorting function. Based on code by
 +      Andrew Schorr.
 +      * symbol.c (free_bcpool): Rework to use an INSTRUCTION_POOL.

 +
 +      * builtin.c (efwrite): Exit successfully upon EPIPE, as SIGPIPE

 +      * config.sub: Updated again.
 +
 +2017-03-22         Andrew J. Schorr     <address@hidden>

 +      field parsing enhancement.
 +
 +2017-03-22         Andrew J. Schorr     <address@hidden>
 +
 +      * gawkapi.h (awk_input_buf_t): Update get_record comment regarding the
 +      new field_width argument.
 +
 +2017-03-21         Andrew J. Schorr     <address@hidden>
 +

 +      array.
 +      (awk_fieldwidth_info_size): Define macro to calculate size of the
 +      variable-length awk_fieldwidth_info_t structure.

 +      this from the value of parse_field -- FIELDWIDTHS parsing uses the
 +      same function.
 +      (calc_mbslen): New function to calculate the length of a multi-byte 
 +      string.
 +      (fw_parse_field): Enhance to support the awk_fieldwidth_info_t

 +      non_fatal_flush_std): Declare new functions.
 +      (ignore_sigpipe, set_sigpipe_to_default,
 +      non_fatal_flush_std): New macros.
 +      * builtin.c (do_fflush): When nonfatal not in force, flush
 +      of stdout/stderr and EPIPE exits, simulating SIGPIPE, as
 +      in nawk/mawk. Flush of other redirections with EPIPE now
 +      also fatals.
 +      (do_system): Use ignore_sipipe and set_sigpipe_to_default
 +      instead of uglier inline ifdefed code.

 +      API field parsing info.
 +      (awk_input_buf_t): Update get_record prototype to use an array of
 +      awk_input_field_info_t instead of integers.
 +      * awk.h (set_record): Change 3rd argument from 'const int *' to
 +      'const awk_input_field_info_t *'.
 +      * field.c (api_fw): Now points to an array of awk_input_field_info_t
 +      instead of integers.
 +      (set_record): Change 3rd argument to point to an array of
 +      awk_input_field_info_t.
 +      (api_parse_field): Update parsing logic to use awk_input_field_info_t
 +      structures instead of an array of integers.
 +      * io.c (inrec, do_getline_redir, do_getline): Change field_width type
 +      from 'const int *' to 'const awk_input_field_info_t *'.

 +
 +      * field.c (normal_parse_field): Renamed from save_parse_field to reflect
 +      better its purpose. Added a comment to explain more clearly what's
 +      going on.
 +      (set_record, set_parser): Rename save_parse_field to normal_parse_field.
 +
 +2017-03-06         Andrew J. Schorr     <address@hidden>
 +
 +      * gawkapi.h (awk_input_buf_t): Remove field_width array and instead
 +      add it as a 6th argument to the get_record function. This should
 +      not break existing code, since it's fine to ignore the additional
 +      argument. Document the behavior of the field_width argument.
 +      * io.c (inrec): Pass pointer to field_width array to get_a_record,
 +      and then hand it off to set_record.
 +      (do_getline_redir): If not reading into a variable, pass pointer to
 +      field_width array to get_a_record and then hand it off to set_record.

 +
 +      * awk.h (set_record): Add a new argument containing a field-width
 +      array returned by an API parser.
 +      (field_sep_type): Add new enum value Using_API.
 +      (current_field_sep_str): Declare new function.
 +      * field.c (save_parse_field): New static variable to save the
 +      parse_field value in cases where it's overridden by API parsing.
 +      (api_fw): New static variable to hold pointer to API parser fieldwidth
 +      array.
 +      (set_record): Add new field-width array argument. If present, API
 +      parsing will override the default parsing mechanism.
 +      (api_parse_field): New field parser using field widths supplied by the
 +      API. This is very similar to the existing fw_parse_field function.
 +      (get_field): Fix typo in comment.
 +      (set_parser): New function to set default parser and check whether
 +      there's an API parser override in effect. Update PROCINFO["FS"] if
 +      something has changed.
 +      (set_FIELDWIDTHS): Use set_parser and stop updating PROCINFO["FS"].
 +      (set_FS): Ditto.
 +      (set_FPAT): Ditto.
 +      (current_field_sep): Return Using_API when using the API field parsing
 +      widths.
 +      (current_field_sep_str): New function to return the proper string
 +      value for PROCINFO["FS"].
 +      * gawkapi.h (awk_input_buf_t): Add field_width array to enable the
 +      parser get_record function to supply field widths to override the
 +      default gawk field parsing mechanism.
 +      * io.c (inrec): Pass iop->public.field_width to set_record as the
 +      3rd argument to enable API field parsing overrides.
 +      (do_getline_redir, do_getline): Ditto.
 +      * main.c (load_procinfo): Use new current_field_sep_str function
 +      instead of switching on the return value from current_field_sep.
 +
 +2017-02-23         Arnold D. Robbins     <address@hidden>
 +
 +      * awk.h (boolval): Return bool instead of int.
 +      * eval.c (eval_condition): Same.
 +      * io.c (pty_vs_pipe): Same
 +      Thanks to Andrew Schorr for pointing these out.
 +
 +2017-02-21         Andrew J. Schorr     <address@hidden>
 +
 +      * NEWS: Document that mktime now takes an optional utc-flag argument.
 +      * awkgram.y (tokentab): Modify mktime entry to indicate that it may
 +      accept two arguments.
 +      * builtin.c (mktime_tz): New function to run mktime in an arbitrary
 +      time zone. Code was copied from the Linux timegm man page.
 +      (do_mktime): Add support for new optional 2nd argument utc-flag by
 +      using the new mktime_tz function.
 +      (do_strftime): Change do_gmt type from int to bool.
 +
 +2017-02-17         Arnold D. Robbins     <address@hidden>
 +
 +      * builtin.c (do_typeof): Handle arguments that have
 +      the NULL_FIELD flag set.
 +
 +2017-02-03         Andrew J. Schorr     <address@hidden>
 +
 +      * awkgram.y (set_profile_text): Improve code clarity by using emalloc
 +      to allocate the string instead of abusing estrdup.
 +
 +2017-02-02         Arnold D. Robbins     <address@hidden>
 +
 +      * awkgram.y (set_profile_next): Allocate an extra byte at the
 +      end for the NUL in case we add a sign. Thanks to Andrew Schorr
 +      for making me look at this code.
 +
 +      And later in the same day:
 +
 +      * awkgram.y (set_profile_next): Undo previous change, since estrdup
 +      handles it, but updated the comments.
 +
 +2017-02-01         Arnold D. Robbins     <address@hidden>
 +
 +      * builtin.c (mbc_char_count): Remove spurious multiplies by
 +      gawk_mb_cur_max. Thanks to Andrew Schorr for making me look
 +      at this code.
 +
 +      Unrelated:
 +
 +      * awkgram.y (make_profile_number): Renamed to ...
 +      (set_profile_next): New function. All calls adjusted. Also improved
 +      use at MPFR number case.
 +
 +2017-01-28         Andrew J. Schorr     <address@hidden>
 +
 +      * io.c (inetfile): Replace strncmp with memcmp in a few places, now
 +      that we are checking string length beforehand.
 +
 +2017-01-27         Andrew J. Schorr     <address@hidden>
 +
 +      * io.c (redirect_string): Check explen positive before accessing *str.
 +      In lintwarn message, use explen string length. Pass length to inetfile.
 +      (devopen): Pass name length to inetfile.
 +      Stop assuming that remoteport is NUL-terminated.
 +      (two_way_open): Pass name length to inetfile.
 +      (inetfile): Stop assuming NUL string termination; add checks to avoid 
 +      string overrun.
 +
 +2017-01-27         Andrew J. Schorr     <address@hidden>
 +
 +      * awk.h (str_terminate_f): New helper function for terminating a string
 +      NODE.
 +      (str_terminate): Macro wrapper to call str_terminate_f.
 +      (str_restore): New macro to restore the string.
 +      * builtin.c (do_strftime): Use str_terminate and str_restore.
 +      (do_dcgettext): Ditto, and remove saved_end flag since equivalent
 +      to testing (t2 != NULL). Fix overrun bug in calculating result
 +      length when !ENABLE_NLS.
 +      (do_dcngettext, do_bindtextdomain): Use str_terminate and str_restore.
 +      * interpret.h (Op_arrayfor_init, Op_indirect_func_call): Ditto.
 +      * str_array.c (env_remove): Ditto.
 +
