	* src/builtin/dkim.bi (do_msgmod): When processing header_replace,

2019-06-18  Sergey Poznyakoff  <gray@gnu.org>

	returned.

2019-01-29  Sergey Poznyakoff  <gray@gnu.org>

	Fixes in runtime memory management

	* src/builtin/sprintf.bi: Don't use pointer to format: the latter
	might be reallocated during stack expansions, and the pointer would
	end up pointing to freed memory area. Another way to fix it would be
	to make env_register_auto and env_pop_auto global and to mark the
	address of pointer with env_register_auto so it would be reallocated
	together with format. However, I wouldn't like to expose too much of
	the internals of prog.c.
	* src/prog.c (env_get_locus)
	(heap_obstack_grow,pushs): Fix argument to env_register_auto.
	(env_register_auto): Check if the argument points to a memory
	location within data segment + stack. This is necessary, because
	heap_obstack_grow registers its argument, which at least in one case
	is a pointer to an automatic variable (see MF_OBSTACK_1GROW in
	builtin/snarf.m4).
	(env_pop_auto,env_unregister_autos)
	(env_fixup_autos): Make static.

	Fix in callout

	* src/main.c (mailfromd_options): Process the --mtasim option immediately.

2018-11-05  Sergey Poznyakoff  <gray@gnu.org>

	Change generation of debug names for built-in modules

2012-08-04  Sergey Poznyakoff  <gray@gnu.org.ua>

	Fix trace output.

	The c-escape filter used by the trace output stream suppresses
	newlines in output.  This is harmless when the output goes to
	syslog, but when it goes to stderr, all trace lines get concatenated
	into a single one on output.  To fix this, newline has to be sent
	directly to the underlying stream, bypassing the filter.

	* src/main.c (trace): Send newline bypassing the c-escape
	filter (which would have converted it to the "\n" sequence).
	This requires MU commit 1cbbd572.

2012-02-08  Sergey Poznyakoff  <gray@gnu.org.ua>

	Fix circular dependency in Makefiles.

	This fixes 2ef494a7.  Make should process the mflib directory
	before src, because the latter relies on status.ex being built.
	On the other hand, mf sources in mflib have to be linted on
	make check.  The solution runs as follows: (1) mflib appears in
	SUBDIRS before src, and (2) src/Makefile.am runs make lint in
	../mflib on make check.

	* tests/module04.at, tests/module06.at,
	tests/static02.at: Reflect the above changes.

	Fix scoping in imported modules.

	When handling `import' (`require') statements, mailfromd
	in some cases could have closed and popped the module lexical
	context before finishing processing its actual contents. In
	particular, if a module ended with a variable or constant
	declaration (e.g. status.mf), this declaration would end up
	in the symbol table of the importing compilation unit. This
	happened because yywrap, triggered by EOF on the module unit,
	caused immediate popping of the lexical contents, whereas
	the parser still had some unreduced symbols on its stack. The
	actual reduction (e.g. of the rule `stmt: CONST value') happened
	after the lexer had supplied next symbol, but by that time the
	original module had already been removed from stack.

	Rewrite preprocessing algorithm.

	The internal preprocessor is removed. Inclusion directives
	(#include, #include_once and #require) are handled directly
	in the lexer. External preprocessor is called for each
	input file separately. This gives a lot of advantages:
	  1. The m4 namespace is kept clean. No unwanted m4 definitions
	  propagate between the files.
	  2. No need to fixup input line numbers.
	  3. End of each compilation unit is handled separately,
	  which allows to implement static variables.
	  4. Cleaner code.

2009-08-31  Sergey Poznyakoff  <gray@gnu.org.ua>

	Begin separation of configuration from filter script.

	The purpose is to separate compilation entities (filter script
	and files included therein), from the actual runtime configuration.
	This changeset introduces a separate mailfromd configuration file,
	located in SYSCONFDIR/mailfromd.conf. The filter script is called
	mailfromd.mf and located in SYSCONFDIR as well (but perhaps it
	should better be located elsewhere?) The old script name,
	mailfromd.rc, was a misnomer since its suffix suggested that the
	file was a configuration file, which as a matter of fact it was
	not. However, if this "legacy" file is present and readable, it is
	used and a warning message is issued.

	All `#pragma option' statements are considered deprecated, and explicit
	warnings are issued if they are used in the script file.

	* NEWS: Update.
	* mfd/appinit.c: New file.

	(mfd_app_init): New prototype.
	* mfd/main.c (need_config): Rename to need_script.
	(struct option_cache): Rename `cumulative' to `flags'.
	New member `confkw'.
	(set_option): Fourth argument specifies whether the
	function was called from a pragma option handler.
	(set_cmdline_option): New define.
	(struct arguments): New data type.
	(init_arguments, flush_trace_module)
	(flush_arguments, destroy_trace_item): New functions.
	(parse_opt): Use set_cmdline_option to set overridable
	options.
	(cb_trace_program): New callback.
	(mf_cfg_param): New statements: syslog-async, trace-actions,

2009-08-27  Sergey Poznyakoff  <gray@gnu.org.ua>

	Fix diagnostic and help messages.

	1. Option descriptions in `--help' output do not constitute
	   conceptual sentences. Therefore, they should not begin
	   with a capital letter, nor end with a final point.
	2. According to standards.texi, a diagnostic message in a
	   non-interactive program "should not begin with a capital letter
	   when it follows a program name and/or file name, because that
	   isn't the beginning of a sentence.  (The sentence conceptually
	   starts at the beginning of the line.)  Also, it should not end
	   with a period."
