This adds support for decrypting PGP/MIME-encrypted parts to
notmuch-show and notmuch-reply. The --decrypt option implies
--verify. Once decryption (and possibly signature verification) is
done, a new part_encstatus formatter is emitted, the part_sigstatus
formatter is emitted, and the entire multipart/encrypted part is
replaced by the contents of the encrypted part.
At the moment only a json part_encstatus formatting function is
available, even though decryption is done for all formats. Emacs
support to follow.
This is primarily for notmuch-show, although the functionality is
added to show-message. Once signatures are processed a new
part_sigstatus formatter is emitted, and the entire multipart/signed
part is replaced with the contents of the signed part.
At the moment only a json part_sigstatus formatting function is
available. Emacs support to follow.
The original work for this patch was done by
Daniel Kahn Gillmor <dkg@fifthhorseman.net>
whose help with this functionality I greatly appreciate.
Future improvements (eg. crypto support) will require adding new part
header. By breaking up the output of part headers from the output of
part content, we can easily out new part headers with new formatting
functions.
Outputting of single MIME parts is moved to an option of notmuch show,
instead of being handled in it's own sub-command. The recent rework
of multipart mime allowed for this change but consolidating part
handling into a single recursive function (show_message_part) that
includes formatting. This allows for far simpler handling single
output of a single part, including formatting.
We rename here in order to make do_show_single into a generic function
for handling output of just a single message, or which format=raw is a
special case. The raw case is handled by setting a new parameter,
params.raw, which is used to tell do_show_single to output a single
message as a raw file.
This is mostly in preparation for much improved part handling to
follow imminently.
A new field "part_sep" is added to the notmuch_show_format structure,
to be used for part separation. This is cleaner than the "first"
argument that was being passed around to the part arguments, and
allows the function that handles overall part output formatting
(show_message_part) to directly handle when outputting the separator.
This simplifies the passing of arguments to the show functions. This
will be very useful as we accumulate more parameters that will need to
be passed. Currently only the entire_thread parameter is passed this
way.
Various show_message* functions require formatting functions, which
were previously being passed individually as arguments. Since we will
need to be needing to passing in more formatting function in the
future (ie. for crypto support), we here modify things so that we just
pass in the entire format structure. This will make things much
simpler down the line as we need to pass in new format functions.
We move the show_format structure into notmuch-client.c as
notmuch_show_format. This also affects notmuch-reply.c, so we create
a mostly-empty format_reply to pass the reply_part function to
show_message_body.
Previously, notmuch show flattened all output, losing information
about the nesting of the MIME hierarchy. Now, the output is properly
nested, (both in the --format=text and --format=json output), so that
clients can analyze the original MIME structure.
Internally, this required splitting the final closing delimiter out of
the various show_part functions and putting it into a new
show_part_end function instead. Also, the show_part function now
accepts a new "first" argument that is set not only for the first MIME
part of a message, but also for each first MIME part within a series
of multipart parts. This "first" argument controls the omission of a
preceding comma when printing a part (for json).
Many thanks to David Edmondson <dme@dme.org> for originally
identifying the lack of nesting in the json output and submitting an
early implementation of this feature. Thanks as well to Jameson Graef
Rollins <jrollins@finestructure.net> for carefully shepherding David's
patches through a remarkably long review process, patiently explaining
them, and providing a cleaned up series that led to this final
implementation. Jameson also provided the new emacs code here.
Since the name of the configuration parameter here is:
maildir.synchronize_flags
the convention is that the functions to get and set this parameter
should match it in name. Hence:
notmuch_config_get_maildir_synchronize_flags
etc. (as opposed to notmuch_config_get_maildir_sync).
This adds group [maildir] and key 'synchronize_flags' to the
configuration file. Its value enables (true) or diables (false) the
synchronization between notmuch tags and maildir flags. By default,
the synchronization is disabled.
This command outputs a raw message matched by search term to the
standard output. It allows MUAs to access the messages for piping,
attachment manipulation, etc. by running notmuch cat rather then
directly access the file. This will simplify the MUAs when they need
to operate on a remote database.

add missing "test_done" to new test script to avoid "Unexpected exit"
error.
Add a new_tags option in the [messages] section of the configuration
file to allow the user to specify which tags should be added to new
messages by notmuch new.
A new 'part' subcommand allows the user to extract a single part from
a MIME message. Usage:
notmuch part --part=<n> <search terms>
The search terms must match only a single message
(e.g. id:foo@bar.com). The part number specified refers to the part
identifiers output by `notmuch show'. The content of the part is
written the stdout with no formatting or identification marks. It is
not JSON formatted.
In the case of notmuch-show, "--format=json" also implies
"--entire-thread" as the thread structure is implicit in the emitted
document tree.
As a coincidence to the implementation, multipart message ID numbers are
now incremented with each part printed. This changes the previous
semantics, which were unclear and not necessary related to the actual
ordering of the message parts.
This was really the last thing keeping the initial run of "notmuch
new" being different from all other runs. And I'm taking a fresh
look at the performance of "notmuch new" anyway, so I think we can
safely drop this optimization.
This is a new notmuch command that can be used to search for all tags
found in the database. The resulting list is alphabetically sorted.
The primary use-case for this new command is to provide the tag
completion feature in Emacs (and other interfaces).

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.

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.
For very large mail boxes, it is desirable to know which files are being
processed e.g. when a crash occurs to know which one was the cause. Also,
it may be interesting to have a better idea of how the operation is
progressing when processing mailboxes with big messages.
This patch adds support for printing messages as they are processed by
"notmuch new":
* The "new" command now supports a "--verbose" flag.
* When running in verbose mode, the file path of the message about to be
processed is printed in the following format:
current/total: /path/to/message/file
Where "current" is the number of messages processed so far and "total" is
the total count of files to be processed.
The status line is erased using an ANSI sequence "\033[K" (erase current
line from the cursor to the end of line) each time it is refreshed. This
should not pose a problem because nearly every terminal supports it.
* The signal handler for SIGALRM and the timer are not enabled when running
in verbose mode, because we are already printing progress with each file,
periodical reports are not neccessary.
I felt sorry for Carl trying to step through an exception from xapian
and suffering from the SIGALARMs..
We can detect if the user launched notmuch under a debugger by either
checking our cmdline for the presence of the gdb string or querying if
valgrind is controlling our process. For the latter we need to add a
compile time check for the valgrind development library, and so add the
initial support to build Makefile.config from configure.

[ickle: And do not install the timer when under the debugger]
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.
This time, things are actually tested. The current results aren't
exactly the same as previous results since the incremental search
doesn't necessarily see all the new messages that pertain to the
thread. This means that some author names are missing.
I plan to fix this by doing an additional database search for all
messages in each thread. Of course, this will also be different than
before since now the result will display *all* authors in the thread
(rather than only those that matched the search) but that's probably
what we really want to display anyway.
It's quite possible for someone to read the documentation and run
"notmuch setup" rather than just "notmuch". In that case, we don't
want to be any less welcoming.
This will allow for things like the database path to be specified
without any cheesy NOTMUCH_BASE environment variable. It also will
allow "notmuch reply" to recognize the user's email address when
constructing a reply in order to do the right thing, (that is, to use
the user's address to which mail was sent as From:, and not to reply
to the user's own addresses).
With this change, the "notmuch setup" command is now strictly for
changing the configuration of notmuch. It no longer creates the
database, but instead instructs the user to call "notmuch new" to do
that.

Keith wrote all the code here against notmuch before notmuch.c was
split up into multiple files. So I've pushed the code around in
various ways to match the new code structure, but have generally tried
to avoid making any changes to the behavior of the code.
I did fix one bug---a missing call to g_mime_stream_file_set_owner in
show_part which would cause "notmuch show" to go off into the weeds
when trying to show multiple messages, (since the first stream would
fclose stdout).
Now that the client sources are alone here in their own directory,
(with all the library sources down inside the lib directory), we can
break the client up into multiple files without mixing the files up.
The hope is that these smaller files will be easier to manage and
maintain.
