after displaying search results

As suggested by Keith in FLAG_PURE_NOT allows for expressions like:
notmuch search NOT tag:inbox
Note that this way a search like:
notmuch search foobar NOT tag:inbox
should not be written instead:
notmuch search foobar AND NOT tag:inbox
In my opinion, the latter feels more natural and is somewhat more explicit.
It gives a better clue of what the search is about instead of assuming that
an implicit AND operator is there.
In particular, notmuch tag -inbox "" tended to take a long time to
run, happened if you hit 'a' on a blank line in the search view and
probably didn't have the desired effect.

I created the notmuch-show-hook precisely so I could add these two
options, but I suspect most people will want them, so I just made them
the default. If you don't want them, you can use remove-hook to get
rid of this.

I wanted to enable got-address-mode and visual-line-mode in my show
windows to make messages easier to read and URLs easier to
follow. This hook allows the user to run arbitrary code each time a
message is shown.

Carl says: This has similar performance benefits as the previous
patch, and I fixed similar style issues here as well, (including
missing more of a commit message than the one-line summary).
This gives a rather decent reduction in number of seeks required when
reading a Maildir that isn't in pagecache.
Most filesystems give some locality on disk based on inode numbers.
In ext[234] this is the inode tables, in XFS groups of sequential inode
numbers are together on disk and the most significant bits indicate
allocation group (i.e inode 1,000,000 is always after inode 1,000).
With this patch, we read in the whole directory, sort by inode number
before stat()ing the contents.
Ideally, directory is sequential and then we make one scan through the
file system stat()ing.
Since the universe is not ideal, we'll probably seek during reading the
directory and a fair bit while reading the inodes themselves.
However... with readahead, and stat()ing in inode order, we should be
in the best place possible to hit the cache.
In a (not very good) benchmark of "how long does it take to find the first
15,000 messages in my Maildir after 'echo 3 > /proc/sys/vm/drop_caches'",
this patch consistently cut at least 8 seconds off the scan time.
Without patch: 50 seconds
With patch: 38-42 seconds.
(I did this in a previous maildir reading project and saw large improvements too)
Previously, Ubuntu 9.10, gcc 4.4.1 was getting:
/usr/bin/ld: lib/notmuch.a(database.o): in function global
constructors keyed to BOOLEAN_PREFIX_INTERNAL:database.cc(.text+0x3a):
error: undefined reference to 'std::ios_base::Init::Init()'
That is, give a nice error message and exit if no search terms are
provided. Thanks to Priit Laes <plaes@plaes.org> for reporting the
error and providing an early version of the fix.
Do not use -C cmdline option of install, older versions, commonly found in
distributions like Debian, do not seem to support it. Running make install
on such systems (tested on Debian Lenny) fails.

This was recently introduced in commit:
64c03ae97f
which was adding extra checks to avoid adding a self-referencing
message.
How many times am I going to fix a dumb regression like this and say
"we really need a test suite" before I actually sit down and write the
test suite?
We take the recently created text from the notmuch manual page and
update the "notmuch help" command to use similar text. In particular,
we add a new "notmuch help search-terms" for documenting the search
syntax that is common to several commands.
I set out merely to add documentation for the recently-added options
for "notmuch search" (--first, --max-threads, and --sort), but ended
up revamping a lot. A significant change is a new SEARCH SYNTAX
section separate from "notmuch search" that is referred to in the
documentation of search, show, reply, and tag.
Also many sections were updated to reflect recent changes, (such as
the dropping of the NOTMUCH_BASE environment variable, the addition of
the .notmuch-config file, etc.)
This is what most people want for a _search_ command. It's often
different for actually reading mail in an inbox, (where it makes more
sense to have results displayed in chronological order), but in such a
case, ther user is likely using an interface that can simply pass the
--sort=oldest-first option to "notmuch search".
Here we're also change the sort enum from NOTMUCH_SORT_DATE and
NOTMUCH_SORT_DATE_REVERSE to NOTMUCH_SORT_OLDEST_FIRST and
NOTMUCH_SORT_NEWEST_FIRST. Similarly we replace the --reverse option
to "notmuch search" with two options: --sort=oldest-first and
--sort=newest-first.
Finally, these changes are all tracked in the emacs interface, (which
has no change in its behavior).
This is one of those cases where total time is not the metric of
interest. We increase the total time of the search, (by doing some
redundant work for the initial threads). But more significantly, we
give the user *some* results nearly instantaneously, (so that the user
might see the result of interest without ever even waiting for the
complete results to come in).
We had exposed this to the internal implementation for a short time,
(only while we had the silly code fetching In-Reply-To values from
message files instead of from the database). Make this private again
as it should be.
Maybe ths lack of this documentation is why I forgot we were actually
storing this and wrote the ugly code to fetch In-Reply-To from message
files rather than from the database.
Which is more consistent with the XREFERENCE prefix used in the terms
in the database. Also remove some stale documentation describing the
removal of resolved references from the database (we no longer do
this).
Calling continue here worked only because we set a flag before the
continue, and, check the flag at the beginning of the loop, and *then*
break. It's much more clear to just break in the first place.
The message file header parsing code parses only enough of the file to
find the desired header fields, then it leaves the file open until the
next header parsing call or when the message is no longer in use. If a
large number of messages end up being active, this will quickly run
out of file descriptors.
Here, we add support to explicitly close the message file within a
message, (_notmuch_message_close) and call that from thread
construction code.

Edited-by: Carl Worth <cworth@cworth.org>:
Many portions of Keith's original patch have since been solved other
ways, (such as the code that changed the handling of the In-Reply-To
header). So the final version is clean enough that I think even Keith
would be happy to have his name on it.
This really should be impossible---if there are no messages, then what
was the thread object created from? During recent debugging, it was
useful to have this error detected and reported.
In our scheme it's illegal for any message to refer to itself, (nor
would it be useful for anything anyway). Cut these self-references off
at the source, before they trip up any internal errors.
