In a prior round of email, Ken mentioned that we would need to key the
mail list entries to something other than the person's actual email
address in order to implement the flexible user information editing
capability of the web (changing one's sendto address, etc.). I agree
that this is needed, sooner or later. Since I haven't seen the code yet,
how difficult is it to just make a unique key for each subscriber and
key the database off that with address as just one value?

I hope I'm not using this list too soon.

(This mail has been generated automatically by the Perl Authors Upload
Server on behalf of the admin andreas.koenig@anima.de)

As already described in a separate message, you're a registered Perl
Author with the userid VPARSEVAL. For the sake of approval I have
assigned to you a change-password-only-password that enables
you to pick your own password. This password is ``a76dd6f7''
(without the enclosing quotes). Please visit either

  https://pause.perl.org/pause/authenquery?ACTION=change_passwd
or
  http://pause.perl.org/pause/authenquery?ACTION=change_passwd

and use this password to initialize yourself in the ordinary
authentication database. Once you have entered your password there,
your one-time password is expired automatically.

If for whatever reason the procedure doesn't work the first time you
try, please visit http://pause.perl.org/password.html and send me a
password of your choice according to these guidelines. Thanks.

Welcome Tassilo von Parseval,

PAUSE, the Perl Authors Upload Server, has a userid for you:

    VPARSEVAL

Once you've gone through the procedure of password approval (see the
separate mail you should receive about right now), this userid will be
the one that you can use to upload your work or edit your credentials
in the PAUSE database.

This is what we have stored in the database now:

  Name:      Tassilo von Parseval
  email:     tassilo.parseval@post.rwth-aachen.de
  homepage:  http://www-users.rwth-aachen.de/tassilo.parseval
  enteredby: Kurt D. Starsinic

Please note that your email address is exposed in various listings and
database dumps. You can register with both a public and a secret email
if you want to protect yourself from SPAM. If you want to do this,
please visit
  https://pause.perl.org/pause/authenquery?ACTION=edit_cred
or
  http://pause.perl.org/pause/authenquery?ACTION=edit_cred

If you need any further information, please visit
  $CPAN/modules/04pause.html.
If this doesn't answer your questions, contact modules@perl.org.

Thank you for your prospective contributions,
The Pause Team

Password update on PAUSE:

VPARSEVAL (Tassilo von Parseval) visited the
password changer on PAUSE at Thu Jul  5 06:17:19 2001 GMT
and changed the password for VPARSEVAL (Tassilo von Parseval).

No action is required, but it would be a good idea if somebody
would check the correctness of the new password.

Thanks,
The Pause

VPARSEVAL (Tassilo von Parseval) visited the PAUSE
and requested an upload into his/her directory.
The request used the following parameters

  HIDDENNAME                 [VPARSEVAL]
  CAN_MULTIPART              [1]
  pause99_add_uri_httpupload [Mail-MboxParser-0.01.tar.gz]
  SUBMIT_pause99_add_uri_httpupload [ Upload this file from my disk ]
  pause99_add_uri_uri        []
  pause99_add_uri_sub        [pause99_add_uri_httpupload]


The request is now entered into the database where the PAUSE Daemon
will pick it up as soon as possible. Allow a few minutes, and be aware
that it may take longer if other requests are running. We proceed only
one at a time.

During upload you can watch ftp://pause.perl.org/tmp/V/VP/VPARSEVAL
(temporary upload directory), and
then https://pause.perl.org/pub/PAUSE/authors/id/V/VP/VPARSEVAL (final
upload directory). The logfile is in
https://pause.perl.org/perl/user/tail_log/2000
(replace 2000 with any offset from the end).

The following module was proposed for inclusion in the Module List:

  modid:       Mail::MboxParser
  DSLIP:       adpOp
  description: simple access to UNIX-mailboxes
  userid:      VPARSEVAL (Tassilo von Parseval)
  chapterid:   19 (Mail_and_Usenet_News)
  communities:

  similar:
    Mail::Cclient Mail::Box

  rationale:

    Mail::MboxParser focuses, unlike Mail::Cclient and Mail::Box, on a
    read-only access to UNIX-mailboxes. It provides wrapper-methods
    derived from MIME::Entity to get a very straight-forward handling of
    attachements. Since most methods are applied to MIME::Entity objects
    the appropriate methods from the MIME::Tools can be directly
    involved to extend functionality. As for namespace: The module
    certainly belongs under the Mail-namespace while MboxParser
    indicates that it is really just about parsing mailboxes and not
    creating them.

The following module was proposed for inclusion in the Module List:

  DSLIP:       adpOp
  description: simple access to UNIX-mailboxes
  userid:      VPARSEVAL (Tassilo von Parseval)
  chapterid:   19 (Mail_and_Usenet_News)
  communities:

  similar:
    Mail::Cclient Mail::Box

  rationale:

    Mail::MboxParser focuses, unlike Mail::Cclient and Mail::Box, on a
    read-only access to UNIX-mailboxes. It provides wrapper-methods
    derived from MIME::Entity to get a very straight-forward handling of
    attachements. Since most methods are applied to MIME::Entity objects
    the appropriate methods from the MIME::Tools can be directly
    involved to extend functionality. As for namespace: The module
    certainly belongs under the Mail-namespace while MboxParser
    indicates that it is really just about parsing mailboxes and not
    creating them.

> Two problems with yours: See the following output from your parser and mine

Ok, the results differ.  That's not a good sign: this means that investigation
is needed.  I'm not a bad guy: if I get a signal from someone that there is
a problem, I fix it.  So please send me the data.

I think fixing problems is more useful than rewriting existing code... there
will be other bugs.

I am rather pleased by these results ;) ;)

> Another thing is: If you really want access to only the mail and, say, the attachements, if there are any, the immense functionality of your modules becomes a little bit confusing...at least I felt so. And often you still have to fiddle around with MIME::Tools which is an equally complex set of modules.

I agree that MIME::Entity, Mail::Internet, MIME::Parser, and MIME::Tools are
quite hard to use.  That's why David Coppit (Mail::Box::FastReader) and I
are planning to replace it.  I have a global design of functionality ready,
but need some hours to write some C ;)  We'll meet at O'Reilly's PerlConf,
in two weeks time.

> Perhaps a structure like that:
> 	Mail::Mbox::Lite	(just the essential things but easy to use)
Don't need that, because my delayed autoloading takes care of that.  One
of the reasons that my module is much faster than yours is because messages
are basically skipped, and only really read when used.

> 	Mail::Mbox::Parser
Will be the C implementation

> 	Mail::Mbox::Parser::Body (perhaps detecting quotations, signatures etc.)
> 	Mail::Mbox::Parser::Header
> 	Mail::Mbox::Parser::Entity
Actually, the planned names will be
  Mail::Message
  Mail::Message::Body
  Mail::Message::Head

Mail::Box::Mbox::Message isa Mail::Box::Message isa Mail::Message

> So, what do you suggest? Of course we could start to write such a

I attach the design, which I discussed (not in full detail) with David.
Maybe you have some bright contributions.  Then... writing the C-code is
probably a good task for me (23 years of experience, mainly in C), and
I have some parts ready.

Then: most difficult is designing tests.  It would be very nice if you
could contribute in testing.

Yes, I want to throw away all old code, for the main reason that it
looks like being OO, but it certainly isn't.  And it is too slow too.
Perl needs a good mail-parser which is fast.

See attachment.

All items with #) are implemented, but those with *) not yet.

Mail::Message     design version 1.113
-------------

Targets
*) replace MIME::Entity, Mail::Internet and MIME::Parser to speed-up
   low-level mail processing.
   Why replace existing modules?
   1) they do not use C on the lowest level.  Rewrite of parts of them
      would be more work than reimplementation of all.
   2) certainly MIME::Entity is not smart enough, not defining enough
      simple objects.
   3) they are not conveniently supporting delay-loading.
   4) they ofter use old-fashioned perl.
   The reimplementation will be done with a close look at the
   well documented code in the two existing modules.
*) extend features of Mail::Folder::FastReader.
*) eventually speed-up all mail-processing Perl-modules.
*) handle Mbox-like folders.
*) handle one file (one message) in MH-like folders.
*) support for delay-loading (saves time and memory)

Parts
*) Mail::Box and grepmail (via Mail::Box?) maintain overview over the
   mail-folders.
*) Mail::Message                  Basic messages as stored in a file.
                                  contains some stuff from Mail::Box::Message
*) Mail::Message::Part            isa Mail::Message
*) Mail::Box::Parser              Contains inlined C for simple character
                                  processing on headers and bodiess.
*) Mail::Box                      Added wrappers around Mail::Box::Parser and
                                  `left-overs' from the replace modules.
*) Mail::Message::Head, comparible to Mail::Head
*) Mail::Message::Head::Field, one line from header.
*) Mail::Message::Body
*) Mail::Message::Body::NotParsed isa Mail::Message::Body
*) Mail::Message::Body::Lines     isa Mail::Message::Body
*) Mail::Message::Body::Scalar    isa Mail::Message::Body
*) Mail::Message::Body::File      isa Mail::Message::Body
*) Mail::Message::Body::Multipart isa Mail::Message::Body

All Mail::Message::Body* may reside in one file.

= Mail::Box additions

Keeps track on:
   - debug-level
   - class of message-objects
   - default class of head-objects       [Mail::Message::Head]
   - default class of body-objects       [Mail::Message::Body::Lines]
   - default class of multiparts-objects [Mail::Message::Body::Multipart]

#) log warnings and errors

#) report warnings and errors

*) my Mail::Message::Head $head = $folder->readHead()
   - return Mail::Message::Head object
   - lines already `unfolded'
   - newlines removed from the end.

*) my $body = $folder->readBody(want => 'Mail::Message::BodyLines'
      , size => $msg->head->get('Content-Length'));
   $msg->body($body);
   - returns any Mail::Message::Body based on flag.
   - calls $args{want}->get($fh)
   - while reading the body, various trics are used to try determining
     where a message ends.  If there is a size in the message-header,
     it should be checked.

*) $msg->sourceCopy($newfile)
   - Copy the message as located in the original folder file into a different
     file.
   - This is much faster than printing the message from structures.
   - The copy will be exact (so even no header-line order changes and such)

*) $msg->writeToFile($newfile, encode => 'BASE64')
   - Write message from perl-structures into file.
   - calls $msg->head->write and $msg->body->write.
   - ability to encode body (see Mail::Message::Body)


= Mail::Box::Parser

Manages a C-pointer to a structure which handles the file-reading.
Keeps track on:
   - filename
   - filehandle
   - fold headerline
   - current linenumber
   - dos-mode (\r\n at end line, while on UNIX)
   - open status

*) my $fh = Mail::Box::Parser->open(...)
   various options on the file are set.  Called by Mail::Box->open

*) $fh->close
   when the application calls close(), but the application might try
   to use it later which shouldn't result in a core-dump.
   - set open status to 'close'
   Called by Mail::Box->close

*) $fh->DESTROY
   perl's DESTROY removes the folder-object
   - free allocated memory.
   Called by Mail::Box->DESTROY

*) my Mail::Message $msg = $fh->read()
   Simplified access to folder to get one message.  It calls getHead and
   getBody.  About the same as:
      my $msg = new Mail::Message(file => $fh);
      $msg->readHead;
      $msg->readBody;
      return $msg;


= Methods in Mail::Message

#) You may supply a Mail::Message::Head and/or ::Body at instantiation.

*) print $msg->fromLine;
   $msg->fromline('From me in 2001');
   get/set from-line for Mbox-like folders

#) my Mail::Message::Head $head = $msg->head;
   Get the headers of this message

#) my Mail::Message::Body $body = $msg->body;
   Get the body of this message

*) $msg->encode(type)  or $part->encode(type)

*) $msg->decode        or $part->decode

*) $msg->signature

*) $msg->remove_sig

*) $reply = $msg->reply;
   Specialy complicated for reply on message-part.


= Mail::Message::Body
  extended by Mail::Message::Body::NotParsed
              Mail::Message::Body::Lines
              Mail::Message::Body::Scalar
              Mail::Message::Body::File
              Mail::Message::Body::Multipart

*) $body->nrlines

*) my $file_offset = $body->begin;

*) my $bytesize = $body->size;

*) if($body->isMultipart)
   same as if($body isa 'Mail::Message::Body::Multipart')

*) my Mail::Message::Body $body = Mail::Message::Body::get($fh)
   To be overruled by each sub-class.

*) $body->addPart(@parts);
   Auto-multiparts message

Conversions:

*) $body->write(FILE)
   results in a move when already BodyFile object
   - supports encoding and decoding
   - automatically updates Content-Length field

*) my $whole = $body->string
   use overload '""' => 'string';
   No work for BodyBlock, otherwise conversion.

*) my @lines = $body->lines
   my $lines = $body->lines;   # returns [$body->lines]
   use overload '@{}' => 'lines';
   No work for BodyLines, otherwise conversion.


= Mail::Message::Part isa Mail::Message

*) my $nr = $part->partnr;
   - All parts shall be sequentially numbered within the message,
     even when the multipart is nested.

But I'm sure more functionality is required here, for instance to
support that attachments reside outside the folder-file to improve
speed in opening the folder.


= Mail::Message::Body::NotParsed isa Mail::Message::Body
  but will autoload on any method performed on the body.

Does not convert body from file to memory-structures, but only collects
info to read it later.

*) my $realbody = $body->load
   returns a real subclass of Mail::Message::Body.


= Mail::Message::Body::Scalar isa Mail::Message::Body

Reads the whole message body into one scalar.


= Mail::Message::Body::Lines isa Mail::Message::Body

Reads the whole message body into a list of scalars, each containing
one line.


= Mail::Message::Body::Multipart isa Mail::Message::Body

Each part is a Mail::Message (-subclass) by itself.

*) print $body->separator || 'no sep yet';
   $body->separator(time . "--$me--$$");
   Get/set part boundary.

*) print $body->preamble      ->string
   Get/set preamble.  Should be empty, but not always is.
   Returns a Mail::Message::Body instance

*) print $body->epilogue      ->string
   Get/set epiloque.  Returns a Mail::Message::Body instance.

*) my @parts = $body->parts()
   get/set all parts

*) my $part = $body->part(42)
   get/set one part   (set to undef means removal)

*) $body->addPart(-1, @parts)
   $body->addPart(@parts)
   Add parts before the specified place, or at the end.


= Mail::Message::Head

Header-fields are used case-insensitive.  

*) my $mime  = $msg->head->get('Subject')
   my @mime  = $head->get('Received')
   return the content of the header-field without trailing newline

*) my @fields = $head->fields;
   ordered list of read headers.  The order is used when write a message
   to a file, while the data is stored in an (unordered) hash with
   lowercased field-names.

*) my Mail::Message::Head::Field $set = $header->set('Field', contents)
   $header->set($mime);
   $header->set(@mime);
   removes old values (when present).  Adds name to end in field-order,
   when new.

*) my Mail::Message::Head::Field @set = $head->add('Received', contents)
   $head->add($mime);
   $head->add(@mime);
   Adds after header-lines with the same name.  Returns all.


= Mail::Message::Head::Field

One line from the header.  This module will supply some methods to
simplify understanding the headerlines, but not as far as Mail::Field
has implemented.

*) my $mime = Mail::Message::Head::Field->new(
      Content-Type => 'text/plain', charset => 'US-ASCII');
   my $mime = Mail::Message::Head::Field->new(
       'Content-Type: text/plain; charset=US-ASCII');
   my $mime = Mail::Message::Head::Field->new(
       Content-Type => 'text/plain; charset=US-ASCII');

*) my $name    = $mime->field;
   => content-type           [lowercased]

*) my $content = $mime->content;
   => 'text/plain; charset=US-ASCII'

*) my $value   = $mime->value;
   => 'text/plain'

*) my $charset = $mime->option('charset');
   => US-ASCII

*) my %options = $mime->options;

*) print $mime->toString;
   => Content-Type: text/plain; charset=US-ASCII
