[PATCH 0/6] Clean up reply's encoding story

[PATCH 0/6] Clean up reply's encoding story

[Austin Clements]

Jeff Stedfast's email about gmime-filter-headers.c possibly being
unnecessary with GMime 2.6 (quoted in id:87bo56viyo.fsf@nikula.org)
sent me on a wild goose chase that led to this patch series.  It
turned out that we *did* need gmime-filter-headers for what we were
doing in the reply text format, but what we were doing made no sense.
Patches 1 through 4 are simply the documentation and tests that I left
in my wake and are harmless to push.  Patch 6 is my conclusion that
how we were handling header encoding in the text reply format made no
sense.  Patch 5 is a step toward patch 6, but makes sense on its own
even if we decide against patch 6.

[PATCH 1/6] lib: Correct out-of-date doc comment

[Austin Clements]

notmuch_message_get_header started returning some headers straight
from the database in 567bcbc, but this comment explicitly claimed all
headers were read from the message file.

[PATCH 3/6] reply: Document the reason for g_mime_filter_headers

[Austin Clements]

Given how long it took me to figure out why we pass the reply headers
through g_mime_filter_headers, it's worth a comment.

[PATCH 5/6] reply: Remove extraneous space from generated References

[Austin Clements]

Previously, the References header code seemed to assume
notmuch_message_get_header would return NULL if the header was not
present, but it actually returns "".  As a result of this, it was
inserting an unnecessary space when concatenating an empty or missing
original references header with the new reference.

This shows up in only one test because the text reply format later
passes the whole reply template through g_mime_filter_headers, which
has the side effect of stripping out this extra space.

[PATCH 6/6] reply: Use RFC 2822/MIME wholly for text format template

[Austin Clements]

Previously, reply's default text format used an odd mix of RFC 2045
MIME encoding for the reply template's body and some made-up RFC
2822-like UTF-8 format for the headers.  The intent was to present the
headers to the user in a nice, un-encoded format, but this assumed
that whatever ultimately sent the email would RFC 2047-encode the
headers, while at the same time the body was already RFC 2045 encoded,
so it assumed that whatever sent the email would *not* re-encode the
body.

This can be fixed by either producing a fully decoded UTF-8 reply
template, or a fully encoded MIME-compliant RFC 2822 message.  This
patch does the latter because it is

a) Well-defined by RFC 2822 and MIME (while any UTF-8 format would be
   ad hoc).

b) Ready to be piped to sendmail.  The point of the text format is to
   be minimal, so a user should be able to pop up the tmeplate in
   whatever editor they want, edit it, and push it to sendmail.

c) Consistent with how frontend capabilities.  If a frontend has the
   smarts to RFC 2047 encode the headers before sending the mail, it
   probably has the smarts to RFC 2047 decode them before presenting
   the template to a user for editing.

Also, as far as I know, nothing automated consumes the reply text
format, so changing this should not cause serious problems.  (And if
anything does still consume this format, it probably gets these
encoding issues wrong anyway.)

Re: [PATCH 6/6] reply: Use RFC 2822/MIME wholly for text format template

[Austin Clements]

Quoth myself on Aug 12 at  2:40 pm:

This was supposed to be "Consistent with frontend capabilities." of
course.

I screwed up when I was rebasing patches in this series.  There's
supposed to be a space before the < above, which should then be removed
in patch 5.  If people take a look over this series, I'll fix this along
with the commit message typo in v2.

The whole series Looks Good To Me (sans known hiccups). I tested the patch 6
affecting 'default' output of notmuch reply bot not json or sexp output
(which I found surprising as so much code was removed). All the explations
in id:1376332839-22825-7-git-send-email-amdragon@mit.edu makes good sense
(but fix also 'tmeplate').

A slighly related note: ^M:s ^J:s (among other chars) don't get encoded
into =?utf-8?b?...?= ...

... also interestingly if U+202E (LEFT-TO-RIGHT OVERRIDE) is in (at least
From) header it disappears from `notmuch reply` default format. In json
and sexp format it disappears in 'reply-headers' but exists in 'headers'.
emacs client seems to use reply-headers as none of the header text lines
in buffer is  rendered RTL.

Do you mean when sending mail, or when replying to a message with
encoded ^Ms and ^Js?

Cool.  My guess would be that one of these it coming from notmuch's
internal header parser (via notmuch_message_get_header) and the other
is coming from GMime's header parser (used in notmuch-show.c)

Pushed the first 3 patches in the series.
