	* printf.c (format_args): Revert fix of 2026-01-15.
	* eval.c (posix_compare): For Cygwin, always uses strcoll().

2026-01-15         Corinna Vinschen      <vinschen@redhat.com>

	UTF-8 and GB18030 allow 4 byte multibyte sequences which
	have to be converted to surrogate pairs on systems with
	wchar_t == UTF-16.  That only affects Cygwin for now, given
	AIX is ignored and native Windows is handled separately.

	This affects the printf() functions because the character and byte
	counting in mbc_char_count() and mbc_byte_count() can't handle
	characters yet which have to be converted to surrogate pairs.

	First of all, both functions do not expect the mbstate_t to be
	in a shift state after it read the first character.  However, this
	is essential to keep track of the full character during surrogate
	handling.  When the code restarts reading the string from the
	beginning for counting, it neglects to reset the shift state,
	so the next read encounters an invalid character sequence.  So make
	sure to reset the shift state when reading from the beginning.

	For Cygwin:

	Add code to mbc_char_count() to count a surrogate pair as a single
	character, not as two characters.

	Add code to mbc_byte_count() to handle only a full surrogate as a
	full character.

2026-01-15         Arnold D. Robbins     <arnold@skeeve.com>

	* printf.c (format_args): For %c, check for -2 return value

2025-10-29         Arnold D. Robbins     <arnold@skeeve.com>

	* re.c (make_regexp): Remove assertion that string is zero
	terminated. It isn't always. Instead, save and restore the
	character past the value of `len'. This required making the
	first parameter not be const anymore. Thanks to Ben Hoyt
	<benhoyt@gmail.com> for the report.

2025-10-27         Arnold D. Robbins     <arnold@skeeve.com>

	* interpret.h (r_interpret): Op_push_arg_untyped: Don't issue
	lint warning for untyped variables, since isarray() and typeof()

2025-10-22         Arnold D. Robbins     <arnold@skeeve.com>

	* interpret.h (r_interpret): For Op_sub_array, don't warn
	about using an uninitialized element, as there is no
	way to create the parent of a subarray first. Thanks to
	Greg Minshall <minshall@umich.edu> for the report.

	* re.c (re_update): Revert previous fix, it didn't do the trick.
	* builtin.c (do_match): If someone passed $0 as the second

2025-10-17         Arnold D. Robbins     <arnold@skeeve.com>

	Fix a bug when match() is called with $0 as the second argument.
	The bug only showed up with assertions enabled.  At the same time,
	add a warning if a regexp constant is used as the first argument.
	Thanks to Daniel David Goren <danieldavidgoren@gmail.com> for
	the report.

	* awkgram.y (snode): For do_match, add a warning if the first
	argument is a regexp constant.
	* re.c (re_update): Unref the original text of the regexp
	if the copy is different from it.

	Unrelated:

	* mpfr.c (mpg_mod): Use mpz_tdiv_r() instead of mpz_tdiv_qr()

	* ext.c (init_extensions_list): Add dummy version for when extensions
	are disabled.
	(load_ext): Update the function argument list for the dummy

	* builtin.c: Move commented out main() test program for add_thousands()
	to ...
	* printf.c: ... here from builtin.c.

2025-07-30         Andrew J. Schorr      <aschorr@telemetry-investments.com>

	Add #ifdef'ed out patch to io.c to use a hashtable to store pipe
	pids to fix a problem with a docker container that defaulted to
	a ulimit of a billion open fds.
	* io.c (write_pipe): If hashing, add a next field.
	(save_pipe): New function to add a pipe to the hash table.
	(gawk_popen_write): If hashing, allocate index of PIPE_HASH_SIZE
	instead of getdtablesize(), and use save_pipe to store the pipe info
	instead of sticking it directly into the open_pipes array.
	(gawk_popen_write_close): If hashing, search the bucket list
	for a matching process. If the match is not at the head of the
	linked list, remove it from the list and free it.

2025-07-29         Arnold D. Robbins     <arnold@skeeve.com>

	Make gawk's system() function smarter. It has to ignore SIGINT
	and SIGQUIT and block SIGCHLD (per POSIX for the C system()
	function.) Thanks to Finn Magnusson <finnmag@yahoo.com> for
	the report.  The test case was:

		gawk 'BEGIN { system("cat"); print "\n1" }'

	Then immediately interrupt the "cat" with a Control-C.
	Older versions of gawk that used the C library system() would
	still print the "1".  Gawk 5.3.1 would not. These changes
	restore the old behavior.

	Note that different versions of awk do different things
	in this test case. BWK awk does print the "1", mawk does not.

	* io.c (wait_any): Now has just the code to do the wait and
	update the status.
	* io.c (wait_any_block_signals): This was originally wait_any().
	Simplified it by having just the signal handling here and making
	a call to wait_any().
	* builtin.c (gawk_system): Added signal handling code to
	ignore/block signals in the parent before the fork, restore
	things in the child before the exec, and restore them in
	the parent after calling wait_any().

2025-07-29         Arnold D. Robbins     <arnold@skeeve.com>

	* awk.h (emalloc_real, ezalloc_real, erealloc_real): Use %zu
	in the error message instead of %ld and casting to long.

2025-07-28         Arnold D. Robbins     <arnold@skeeve.com>

	Rationalize do_traditional throughout the code base:

	1. Bring things into sync with current BWK awk.
	2. Change `do_posix || do_traditional' tests to just `do_traditional'
	since --posix automatically also turns on do_traditional.

	* builtin.c (do_system): Remove old code that divided the
	exit status by 256 if do_traditional. BWK awk no longer
	does that.

	* io.c (redirect): Don't issue a lint complaint if the
	redirect string is a STRNUM, because a filename could be
	numeric, and that shouldn't be flagged by lint if it came
	from user input.

2025-05-22         Arnold D. Robbins     <arnold@skeeve.com>

	Persistent memory and extension functions don't mix. Make
	it a fatal error that gawk catches instead of weird errors
	and core dumps.  Issue reported by "Stan Marsh" (sic)
	<gazelle@xmission.com>.

	* awk.h (using_pma): New variable, add extern declaration.
	* ext.c (load_ext): If using_pma, fatal message.

2025-05-18         Arnold D. Robbins     <arnold@skeeve.com>

	* eval.c (update_ERRNO_int, update_ERRNO_string, unset_ERRNO):
	If do_traditional, return early.
	* io.c: As needed, for calls to the above, remove test for
	! do_traditional.  The code was not being consistent about

	* re.c (research): Undo previous change. MINRX_REG_NOSUB
	is a flag for compiling the regex, not execing it. :-(
	In gawk, we don't know at regex compile time if we will
	need the subpatterns or not.  Oh well.

2025-04-28         Arnold D. Robbins     <arnold@skeeve.com>

	* re.c (research): If not need_start, add MINRX_REG_NOSUB

	str_array.c, symbol.c: Update copyright year.

2025-02-14  Paul Eggert  <eggert@cs.ucla.edu>

	* main.c (main): Omit BSD hack that misbehaved by putting stderr
	in O_APPEND mode, which can cause later stderr output to be put in
	the wrong place, even after Gawk has exited and even if Gawk
	never outputs anything.  For example, the shell command
	"echo abcdefgh >foo; (gawk 'BEGIN{}'; echo ouch >&2) 2<>foo"
	incorrectly appended "ouch" to the end of foo rather than
	correctly overwriting the start of "foo" with "ouch".
	The BSD issue can be addressed in the test case instead.

	and in posix/gawkmisc.c. Instead, call os_disable_aslr().

2025-02-05         Arnold D. Robbins     <arnold@skeeve.com>

	* main.c (enable_pma): Remove unused argc parameter and adjust
	call.  Add call to unsetenv() for magic env var if it was

	* node.c (r_unref): For Node_var_new, free the vname.

2025-02-05         Arnold D. Robbins     <arnold@skeeve.com>

	Stylistic cleanups and small code cleanups.

	* array.c, eval.c, ext.c, interpret.h: Some stylistic cleanups.

	(adjust_param_node): New function.
	(adjust_fcall_stack): Extra handling of Node_elem_new nodes.
