Re: [Nmh-workers] More configuration stuff (acconfig.h)

2012-01-07 13:45:14
Hi Nick,

nmh 1.4 is out. I hope you have some time soon to package it up.

Could you please comment on Ken's questions about the following
configuration items? Since I like the way you configure nmh on Debian,
I'd like to ensure that his suggestions are consistent with the way you
configure nmh. Thanks!

Alright, in preparation for finally cleaning up our suboptimal autoconf
mess, I am tackling acconfig.h (a template which users can edit to
change defaults).  My feeling is all of that should either be controlled
by autoconf or we take a decision on whether or not to keep or remove
that code.  Here is the list:

LOCKDIR               - A directory to place lock files in if you're using
                DOT_LOCKING.  I've never been happy with nmh's use of
                dot locking, but do people actually use this?  It's
                easy enough to add the support for this to autoconf.

DBMPWD                - The comment says "Define this if your passwords are
                stored in some type of distributed name service, such as
                NIS, or NIS+."  This only affects aliasbr.c ... and I
                guess what it does is controls whether or not names
                are cached from calls to getpwnam().  This has been
                turned on forever, I propose just removing the #ifdefs
                and making that code the default.

DUMB          - Strangely, turning ON DUMB means you get an RFC 822
                parser.  If DUMB is NOT defined, you get MMDF and UUCP
                parsing as well.  I'm going to go out on a limb here and say
                we can safely remove MMDF & UUCP address parsing :-)
                Oh, on that note there's some code #ifdef'd as BANG
                which uses UUCP mailing syntax.  I'm just going to go
                ahead and remove that because I am 100% sure no one
                needs it.

REALLYDUMB    - What this does is prevent adrsprintf() from appending a
                local hostname if a username doesn't have one.  You know,
                I really think this should be a run-time option instead.
                Anyone care if I make it so it is?  (The default can
                be off to match current behavior).

FIX_NON_Y2K_COMPLIANT_MUA_DATES
              - Meh, at this point I'd say garbage collect this code,
                but I have no strong feelings.  Either we should keep it
                and remove the #ifdefs, or get rid of it entirely.
                Thoughts?

RPATHS                - Construct Return-Path headers from "From " lines.
                I say keep it, since it's been around forever (a fair
                amount of code, actually).

SLOCAL_MBOX   - If defined, use mbox format with slocal when saving to
                your mail spool, otherwise, use MMDF.  I say keep it
                and ditch MMDF support.

MHRC          - Handle the ~ for filenames; this is a keeper, right?

BUILTIN_FTP   - This was the only code I didn't add IPv6 code to.  It's
                turned on right now, but I have to question how useful it
                is (it's built-in ftp support for mhn).  I haven't seen
                MIME messages with external-body parts in forever, and
                even if we did get any I think this work should be forked
                off to an external ftp program or something like curl.
                Thoughts?  Actually, I wonder how many MUAs support
                MIME external-body anyway (okay, a quick Google shows
                that it's non-zero, but I suspect that a lot of it is
                done via http rather than ftp anyway).

POPSERVICE    - Easy enough to autoconf it, but it's command-line selectable
                anyway.  Maybe simply hardcode the default?

DEFAULT_FOLDER_MODE   - Leave these two as hardcoded defaults?
DEFAULT_MESSAGE_MODE

LINK          - The same?

ATTVIBUG      - Is this an issue anymore?
