We want to allow the user to be able to use search expressions with
parentheses and semi-colons, etc. and we definitely don't want the
shell interpreting those!
Previously, our emacs interface was waiting for the "notmuch search"
to complete before it would display anything. Now, we execute the
process asyncrhonously and filter results as they come in.
This takes advantage of the recent work to make "notmuch search"
results stream out steadily. The result is that some search results
will be available nearly instantly and the user can navigate and view
those while additional results continue loading.
Xapian provides an interator-based interface to all search results.
So it was natural to make notmuch_messages_t be iterator-based as
well. Which we did originally.
But we ran into a problem when we added two APIs, (_get_replies and
_get_toplevel_messages), that want to return a messages iterator
that's *not* based on a Xapian search result. My original compromise
was to use notmuch_message_list_t as the basis for all returned
messages iterators in the public interface.
This had the problem of introducing extra latency at the beginning
of a search for messages, (the call would block while iterating over
all results from Xapian, converting to a message list).
In this commit, we remove that initial conversion and instead provide
two alternate implementations of notmuch_messages_t (one on top of a
Xapian iterator and one on top of a message list).
With this change, I tested a "notmuch search" returning *many* results
as previously taking about 7 seconds before results started appearing,
and now taking only 2 seconds.
Having actually implemented this, I realized that my
initial approach of providing a function to configure
a button was wrong. Instead I've replaced that with
button types. This then makes it possible to provide
the fully expanded view when all threads in a message
are unread.
It also has the potential to allow global-expansion functions
if that is desireable
This is the same as with citations and signatures.
I used an ellipsis here for the invisible region, which
I think make it more obvious that there are extra headers.
MH-e used this for extra long To/CC headers.
Previously, notmuch_query_search_threads would do all the work, so the
caller would block until all results were processed. Now, we do the
work as we go, as the caller iterates with notmuch_threads_next. This
means that once results start coming back from "notmuch search" they
just keep continually streaming.
There's still some initial blocking before the first results appear
because the notmuch_messages_t object has the same bug (for now).
This was a poor workaround around the fact that the existing
notmuch_threads_t object is implemented poorly. It's got a fine
iterartor-based interface, but the implementation does all of the
work up-front in _create rather than doing the work incrementally
while iterating.
So to start fixing this, first get rid of all the hacks we had working
around this. This drops the --first and --max-threads options from the
search command, (but hopefully nobody was using them
anyway---notmuch.el certainly wasn't).
The domain is alway case insensitive, but in principle the username is
case sensitive. Few systems actually enforce this so I think a good
default is to treat the entire address as case insensitive, it will
eliminate a lot of superfluous self-addressed messages and reply from
the correct address in these cases.

This way, the user gets a steady (but bursty) stream of reults. We
double the chunk size each time since each successive chunk has to
redo work from all previous chunks.
Of course, the overall time is thereby slower, as the price we pay for
increased responsiveness. With a search returning about 17000 thread
results I measured a total time of 48.8 seconds before this change and
58.4 seconds afterwards.
The rudimentary aspect here is that the date ranges are specified with
UNIX timestamp values (number of seconds since 1970-01-01 UTC). One
thing that can help here is using the date program to determins
timestamps, such as:
$(date +%s -d 2009-10-01)..$(date +%s)
Long-term, we'll probably need to do our own query parsing to be able
to support directly-specified dates and also relative expressions like
"since:'2 months ago'".
Folder mode takes a (user-configurable) list of search patterns and
produces a list of those patterns and the count of messages that they
match. When an entry in this list is selected, a search window with
the defined search is opened. The set of folders is defined as a
list, each element contains the name of the folder and the query string
to count.

Getting the count of matching threads or messages is a fairly
expensive operation. Xapian provides a very efficient mechanism that
returns an approximate value, so use that for this new command.
This returns the number of matching messages, not threads, as that is
cheap to compute.

Selecting text in the search view isn't all that useful, so instead,
make mouse-1 clicks actually show the thread you click on. It's almost
like direct manipulation or something.

When running "notmuch new --verbose", ANSI escapes are used. This may not be
desirable when the output of the command is *not* being sent to a terminal
(e.g. when piping output into another command). In that case each file
processed is printed in a new line and ANSI escapes are not used at all.
I configured my database.path with a trailing /, and after running notmuch
new every notmuch search would fail with error messages like this:
Error opening /inbox/cur/1258565257.000211.mbox:2,S: No such file or directory
The actual bug was in the filename normalization for storage in the
database. The database.path was removed from the full filename, but if
the database.path from the config file contained a trailing /, the
relative file name would retain an extra leading /... which made it look
like an absolute path after it was read out from the DB.

I had these notes sitting in an uncommitted file that was cluttering
up my "git status" output. This cleans that up, and also shares the
ideas with the wider community.
