This reverts commitc7b28419ab. The reverted change fails to sort threads correctly when there is an empty container, serving as a parent to orphan messages, in the thread tree as demonstrated by the test in commitf49296759e("tests: threads: Test if orphan message promotes its thread"). Also, the reverted commit introduces a performance hit. The time it takes to sort threads has increased roughly by a factor of 4. Current state: $ perf stat --event=task-clock --repeat=10 -- \ mu find maildir:/INBOX -n 1 -t > /dev/null Performance counter stats for 'mu find maildir:/INBOX -n 1 -t' (10 runs): 4967.692519 task-clock (msec) # 1.000 CPUs utilized ( +- 0.14% ) 4.969247128 seconds time elapsed ( +- 0.14% ) With the reverted patch applied: $ perf stat --event=task-clock --repeat=10 -- \ mu find maildir:/INBOX -n 1 -t > /dev/null Performance counter stats for 'mu find maildir:/INBOX -n 1 -t' (10 runs): 1231.761588 task-clock (msec) # 0.996 CPUs utilized ( +- 1.02% ) 1.236209133 seconds time elapsed ( +- 1.08% ) The benchmark was ran on a maildir with ~16k messages: $ mu find maildir:/INBOX | wc -l 16503
README
======
Welcome to mu!
---------------
Given the enormous amounts of e-mail many people gather and the importance of
e-mail message in our work-flows, it's essential to quickly deal with all that
mail - in particular, to instantly find that one important e-mail you need right
now.
[mu] is a tool for dealing with e-mail messages stored in the
Maildir-format. =mu='s purpose in life is to help you to quickly find the
messages you need; in addition, it allows you to view messages, extract
attachments, create new maildirs, and so on. See the [mu cheatsheet] for some
examples. =mu= is fully documented.
After indexing your messages into a [Xapian]-database, you can search them using
a custom query language. You can use various message fields or words in the
body text to find the right messages.
Built on top of the mu, are some extensions (included in this package):
- mu-for-emacs ([mu4e]): a full-featured e-mail client that runs inside emacs
- [mu-guile]: bindings for the Guile/Scheme programming language (version 2.0
and later)
- a toy GTK+-interface called 'mug' (in the 'toys/' subdir)
=mu= is written in C and a bit of C++ (to interface with Xapian), with =mu4e=
written in [Emacs-Lisp] and =mu-guile= in a mix of C and Scheme.
Note, =mu= is available in Debian/Ubuntu under the name =maildir-utils=;
apparently because they don't like short name. It's also possible to confuse
that name with the [GNU Mailutils] project (which is totally unrelated) - but
now you have been warned.
