Per the draft, grouping by subject is skipped and
threads (toplevel messages) are sorted by INTERNALDATE,
while the messages within the threads are still sorted
by SENTDATE.<br>
<br>
I confirmed that THREAD=REFERENCES is still correct, but
I have nothing to compare THREAD=REFS results to. The
current threading in Thunderbird is close, but it might
be using INTERNALDATE throughout.<br>

The attached patch is what I was thinking in terms of
implementation. It skips the grouping by subject for
REFS, but I didn't do the REFS-specific date handling.
Contrary to what the THREAD=REFS draft says, I'm not
sure if the special date handling should be done in
step 4 or 6. I would have to did deeper into the code
to see where is belongs.<br>

I will ask Dovecot guys why they choose to keep

<p>Is there an actual RFC? All I find is
draft-ietf-morg-inthread-01. Looking at
that draft, the only difference between
REFS ad REFERENCES is this:</p>
<pre class="newpage"> THREAD=REFS sorts threads by the most recent INTERNALDATE in each
thread, replacing THREAD=REFERENCES step (4). This means that when a
new message arrives, its thread becomes the latest thread. (Note
that while threads are sorted by arrival date, messages within a
thread are sorted by sent date, just as for THREAD=REFERENCES.)
</pre>
This being the case, I don't think we need
two copies of the threading functions. I'd
modify the exiting functions to take an
additional parameter to specify whether
we're doing REFS or REFERENCES and then
have 2 wrapper functions which call the
main function with the parameter set
appropriately for the given algorithm.<br>

checking against dovecot

the RFC on refs says ordering of dates

like:</div>
<div style="font-family:

renaming all functions like

"index_thread_references"</div>
<div style="font-family:

duplicate them as
"index_thread_refs"</div>
<div style="font-family:

"references" alg call the

<div style="font-family:

support for "refs" in

call the "refs" funcs</div>

As long as you mean making these

To implement this you want
to look at index.c in the
Cyrus source and add
another entry to the
thread_algs[] array. I'm
guessing that you can
reuse a lot of the
existing
index_thread_ref() code
(which is probably needs
to be renamed to
index_thread_references()).<br>

That sounds about
right from what I
remember of
THREAD=REFERENCES
(which I co-authored
and implemented) and
THREAD=REFS (which I
think was last
documented in 2010).<br>
