        Minor changes


2025-09-20  Sergey Poznyakoff  <gray@gnu.org>

        Bugfix

        * src/engine.c (mlfi_negotiate): Register "i" for
        smtp_state_connect, instead of for the first state for which a
        prog is declared.  This fixes a bug introduced by 5ffc17f7e6. 
        Since that commit, xxfi_connect field of smfilter is always
        initialized, so the first_used_state variable and the logic
        associated with it loses its sense.  The first entered handler
        is mlfi_connect, and it is the handler which triggers invocation 
        of prog begin, if such is defined.  Now, "i" should be available
        in all handlers, hence it must be registered for
        smtp_state_connect.

2024-08-26  Sergey Poznyakoff  <gray@gnu.org>

        Bugfix

        * src/drivers.c (optimize_type_sedcomp): Don't install NULL
        pointer into transform table to avoid segfaulting during further
        optimizations.

2024-06-25  Sergey Poznyakoff  <gray@gnu.org>

        callout: return the "less critical" answer if no MX gives a
        definite one.

        E.g., if among three MXs one returns mf_timeout, another one
        mf_temp_failure and yet another one mf_failure, the result of
        callout_mx will be mf_temp_failure.

        * src/callout.c (callout_mx): Assign weights for various status 
        codes. Unless some of the MXs returns a definite answer, the

2023-11-13  Sergey Poznyakoff  <gray@gnu.org>

        callout: use TLS if the server fails with 530 after RCPT TO

        Some servers claim that TLS is required after RCPT TO command. 
        Reported by Jan in
        <alpine.LNX.2.00.2311030012150.22092@cedric.unob.cz>

        * src/callout.c (callout_mode): New enum.
        (callout_io): Additional callout_mode argument instructs the 
        function how to handle the callout. The function calls itself 
        recursively as needed. Maximum recursion depth is 2, so that's 
        not much of a problem. All uses changed.

2023-11-13  Sergey Poznyakoff  <gray@gnu.org>

        Minor fix

        * lib/srvman.c (set_signal_handlers, restore_signal_handlers):
        Signal numbering starts at 1.

2023-09-26  Sergey Poznyakoff  <gray@gnu.org>

2023-07-19  Sergey Poznyakoff  <gray@gnu.org>

        Fix handling of positional parameters.

        The check for positional parameters usage introduced in 20cdf6a2 
        used wrong lexical context and caught otherwise legitimate use 
        cases. This was aggravated by the fact that positional
        parameters in quoted strings were handled by another code, and
        all available tests were using positionals in strings, due to
        which they were unable to catch the bug.

        Reported by Jan Rafaj.

        create_node_arg, which use.

        Fix implicit registering of the $i macro

        The macro is used in diagnostic messages and is therefore always 
        requested. This was broken in 4b12de188, which changed the

        Fix source location tracking after emitted action hook call

        See also 5133ed34.

2023-06-14  Sergey Poznyakoff  <gray@gnu.org>

        Introduce action hooks

        Action hook is a special prog handler which, if defined, is
        implicitly invoked before each reply action (such as accept,
        reject, etc.) It is passed the action code, basic and extended
        SMTP codes and textual message string as its arguments.  Action
        hooks provide a convenient way for logging and accounting of
        executed actions.

        This commit also fixes several bugs found while developing the
        new feature.

        * configure.ac: Version 8.16.90

        * gacopyz/server.c (format_argv): Don't output extra \0 at the
        end of the list.
        * global.def (DEFAULT_REJECT_CODE)
        (DEFAULT_TEMPFAIL_CODE): New constants.
        (MAX_E_EXCEPTIONS): Fix definition.

        (noinst_HEADERS): Add milter.h
        * mflib/mfh.awk: Handle multiline "const" blocks.

        * mtasim/mtasim.c (set_expected_regex): New function.

        New syntax for special handlers

        Special handlers are defined using the "prog" keyword, as the 
        rest of handlers.  This fixes, in particular, a name clash
        between the 'shutdown' handler and eponymous function.

        This commit also restores handling of identifiers after
        'require' and initial 'from' keywords, which was inadvertently
        lost long ago
        (commit bd6d33fe0).  Perhaps it wasn't needed so much, but for
        the time being let it be.

        * NEWS: Document changes.

        definitions/ Remove tokens: T_BEGIN, T_STARTUP, T_SHUTDOWN,
        T_END. Correctly report state handler duplications.
        * src/lex.l: Swich to XIDENT state after 'prog', 'require' and 
        initial 'from'. Remove unneeded tokens. Use strtol instead of
        strtoul to parse numeric constants.

        * tests/progdup.at: New test.

        Fix discrepancy between normal operation and "run" mode.

        In run mode, main was called with the return pc value 0 in the 
        calling frame.  This means that stopping the program relied on 
        two unsigned wraparounds: first when decrementing the return pc 
        in instr_return, and second when incrementing it again in the 
        eval_environment loop.  As a side effect, this made
        runtime_stack_trace go astray and coredump when used in run
        mode.

        This commit reserves the slot at pc 1 as return point for "main" 
        in run mode and thus fixes the discrepancy.

        NB: Another way to fix it would be to rewrite the loop in 
        eval_environment.  But that doesn't seem to be worth the 
        candles.

        * src/gram.y (parse_program): Remove call to code_immediate - 
        out of place here.

        The "sed" function (actually, a statement) transforms its first
        argument using the sed expressions given in its subsequent

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:

        http://mail.gnu.org.ua/mailman/listarchive/bug-mailfromd/2019-06/msg00001.html

        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.

2012-07-15  Sergey Poznyakoff  <gray@gnu.org.ua>

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.
        (input_file_id): New variable

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
        * mfd/gram.y (pragma_option): Update call to set_option. Pass

        (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.

        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.
