2019-09-07  Sergey Poznyakoff  <gray@gnu.org>

        Minor fixes

        * src/main.c (mf_cfg_param): Remove the surplus "database" 
        section: it is already included in srvcfg.c
        * src/prog.c (env_register_auto): Use mu_diag_cont_printf to 
        continue diagnostic message without inserting unnecessary
        <> directives (perhaps should be fixed in mailutils).

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

        Don't accept database types not supported by mailutils

        For details, see the last paragraph in:

        never 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.

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.

        * Makefile.am (SUBDIRS): Restore mflib to its proper place.
        * mflib/Makefile.am (check-am): Remove rule.

2009-10-02  Sergey Poznyakoff  <gray@gnu.org.ua>

        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.

2009-09-20  Sergey Poznyakoff  <gray@gnu.org.ua>

        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.

        * mfd/lex.l (struct inctx): New struct.

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/Makefile.am (mailfromd_SOURCES): Add appinit.c

        NULL locus to initialize_variable.
        (initialize_variable): Issue the "variable already initialized" 
        warning only if previous initialization was in a source file, 
        not from command line or a configuration statement.
        * mfd/mailfromd.h (DEFAULT_SCRIPT_FILE): Change definition.
        (LEGACY_SCRIPT_FILE): New define.
        (DEFAULT_CONFIG_FILE): New define.
        (set_option): Takes four arguments.

        (mailfromd.rc), if present.

        specifying the length of the first.

        (enable_prog_trace,disable_prog_trace): Rewrite using

        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."

	Started major rewrite. The final aim is to make the internal
	program reentrant and to make it stop when it is trying to
	reference a non-existend sendmail variable. Then, the milter
	handler should return SMFIS_CONTINUE to pass control over to the
	next handler. That, in turn, should restart program execution in
	the hope that Sendmail has provided the variable on this stage. If
	it does not the process continues.
