Buffer redisplay requires traversing the buffer's invisibility spec for every part of the display that has an 'invisible text or overlay property. Previously, the search buffer's invisibility spec list contained roughly one entry for each search result. As a result, redisplay took O(NM) time where N is the number of visible lines and M is the total number of results. On a slow computer, this is enough to make even buffer motion noticeably slow. Worse, during a search operation, redisplay is triggered for each search result (even if there are no visible buffer changes), so search was quadratic (O(NM^2)) in the number of search results. This change switches to using a single element buffer invisibility spec. To un-hide authors, instead of removing an entry from the invisibility spec, it simply removes the invisibility overlay from those authors. I tested using a query with 6633 results on a 9 year old machine. Before this patch, Emacs took 70 seconds to fill the search buffer; toward the end of the search, Emacs consumed 10-20x as much CPU as notmuch; and moving point in the buffer took about a second. With this patch, the same query takes 40 seconds, Emacs consumes ~3x the CPU of notmuch by the end, and there's no noticeable lag to moving point. (There's still some source of non-linearity, because Emacs and notmuch consume roughly the same amount of CPU early in the search.) |

Notmuch - thread-based email index, search and tagging. Notmuch is a system for indexing, searching, reading, and tagging large collections of email messages in maildir or mh format. It uses the Xapian library to provide fast, full-text search with a convenient search syntax. Notmuch is free software, released under the GNU General Public License version 3 (or later). Building notmuch ---------------- See the INSTALL file for notes on compiling and installing notmuch. Running notmuch --------------- After installing notmuch, start by running "notmuch setup" which will interactively prompt for configuration information such as your name, email address, and the directory which contains your mail archive to be indexed. You can change any answers later by running "notmuch setup" again or by editing the .notmuch-config file in your home directory. With notmuch configured you should next run "notmuch new" which will index all of your existing mail. This can take a long time, (several hours) if you have a lot of email, (hundreds of thousands of files). When new mail is delivered to your mail archive in the future, you will want to run "notmuch new" again. These runs will be much faster as they will only index new messages. Finally, you can prove to yourself that things are working by running some command-line searches such as "notmuch search from:someone@example.com" or "notmuch search subject:topic". See "notmuch help search-terms" for more details on the available search syntax. The command-line search output is not expected to be particularly friendly for day-to-day usage. Instead, it is expected that you will use an email interface that builds on the notmuch command-line tool or the libnotmuch library. Notmuch installs a full-featured email interface for use within emacs. To use this, first add the following line to your .emacs file: (require 'notmuch) Then, either run "emacs -f notmuch" or execute the command "M-x notmuch" from within a running emacs. If you're interested in a non-emacs-based interface to notmuch, then please join the notmuch community. Various other interfaces are already in progress, (an interface within vim, a curses interface, graphical interfaces based on evolution, and various web-based interfaces). The authors of these interfaces would love further testing or contribution. See contact information below.
