We don't love the mbox format, but it's still sometimes the most
practical way to share a collection of messages as a single file.
Here we implement the "mboxrd" variant of the mbox file format. This
variant applies reversible escaping by prefixing a '>' character to
all lines in the email messages matching the regular expression:
"^>*From "
This allows the escaping to be reliably removed. A reader should remove
a '>' from any line matching the regular expression:
"^>>*From "
More details on the mboxrd formats (and others as well) can be found
here:

Micah Anderson reported an issue where a message failed to display in
the emacs interface, (it instead gave an error, "json-read-string: Bad
string format").
Micah tracked this down to the json output from "notmuch show" being
interrupted by a GMime error message:
gmime-CRITICAL **: g_mime_stream_filter_add: assertion
`GMIME_IS_FILTER (filter)
I tracked this down further to notmuch passing a NULL value to
g_mime_stream_filter_add. And this was due to calling
g_mime_filter_charset_new with a value of "unknown-8bit".
So we add a test message withe a Conten-Type of "text/plain;
charset=unknown-8bit" from Micah's message. Then we fix "notmuch show"
to test for NULL before calling g_mime_stream_filter_add. Bug fixed.
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.
Include a 'date_unix' and 'date_relative' field in the JSON output for
each message. 'date_relative' can be used by a UI implementation,
whereas 'date_unix' is useful when scripting.
I ran into this while looking at the vim plugin. Vim's system() call
redirects output to a file and it was missing many of the part{ lines.
If stream_stdout is setup too early, it will overwrite the part start
when notmuch is redirected to a file.
Reviewed-by Carl Worth <cworth@cworth.org>: GMime is calling fseek
before every write to reset the FILE* to the position it believes is
correct based on the writes it has seen. Our code was getting
incorrect results because our GMime writes were interleaved with
non-GMime writes via printf.
The bug appears when writing to a file because it's seekable, but not
when writing to a pipe which is not.
The previous json patches forgot to add the notmuch tags to the json
output. This is inconsistent to the text output so here they are. We
just output a 'tags' field that sends notmuch tags as a json array.

This is a fairly old regression. There has always been code to avoid
printing empty headers (such as Cc or Bcc with no values), but it has
been broken since notmuch_message_get_header was changed to return
an empty string rather than a NULL pointer for these fields.
We rename 'has_more' to 'valid' so that it can function whether
iterating in a forward or reverse direction. We also rename
'advance' to 'move_to_next' to setup parallel naming with
the proposed functions 'move_to_first', 'move_to_last', and
'move_to_previous'.
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.
When "notmuch show" was recently modified to not show an entire thread
by default, it also lost all capability to properly order the messages
in a thread and to print their proper depth. For example, the command:
notmuch show thread:6d5e3e276461188c5778c9f219f63782
had dramatically different output than:
notmuch show --entire-thread thread:6d5e3e276461188c5778c9f219f63782
even though both commands were selecting and displaying the same set
of messages. The first command would diplay them "flat", (all with
depth:0), and in strict date order; while the second command would
display them "nested" (with depth based on threading), and in thread
order.
We now fix "notmuch show" without the --entire-thread option to also
display nested and thread-ordered messages.
If some messages in the thread are not included in the displayed
results, then they are not counted when computing depth values.
This patch changes the default behaviour of notmuch show to display only
messages that match the search expression. However, --entire-thread
option is provided to display all messages in threads that matched the
search expression.
It is deemed that will be more useful for human users on the command line.
Scripts can be modified to include the --entire-thread option so that they
can display all messages once more.
Example:
$ notmuch search subject:git AND thread:23d99d0f364f93e90e15df8b42eddb5b
thread:23d99d0f364f93e90e15df8b42eddb5b July 31 [4/12] Johan Herland; [RFCv2 00/12] Foreign VCS helper program for CVS repositories (inbox unread)
Note that in this thread 4 out of 12 messages matched. The default show
behaviour is to show only those messages that match:
$ notmuch show subject:git AND thread:23d99d0f364f93e90e15df8b42eddb5b | grep 'message{' | wc -l
4
With the --entire-thread option the output will contain all dozen
messages:
$ notmuch show --entire-thread subject:git AND thread:23d99d0f364f93e90e15df8b42eddb5b | grep 'message{' | wc -l
12

The show command outputs all messages in the threads that match the
search-terms. This patch introduces a 'match:[01]' entry to the 'message{'
line output by the show command. Value of 1 indicates that the message is
matching the search expression.

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).
Pass the message through the charset filter so that we can view
messages wrote in different charset encoding.

We only rarely need to actually open the database for writing, but we
always create a Xapian::WritableDatabase. This has the effect of

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.

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.
We now properly analyze the in-reply-to headers to create a proper
tree representing the actual thread and present the messages in this
correct thread order. Also, there's a new "depth:" value added to the
"message{" header so that clients can format the thread as desired,
(such as by indenting replies).
It's funny that I picked up the habit of always including a space
before a left parenthesis from Keith, and now he's in the habit of
contributing code without it.
The library interface now allows the caller to do incremental searches,
(such as one page of results at a time). Next we'll just need to hook
this up to "notmuch search" and the emacs interface.
All of the following commands:
notmuch dump
notmuch reply
notmuch restore
notmuch search
notmuch show
notmuch tag
were calling notmuch_database_open with an argument of NULL. This was
a legitimate call until the recent addition of configuration, after
which it is expected that all commands will lookup the correct path in
the configuration file. So fix all these commands to do that.
Also, while touching all of these commands, we fix them to use the
talloc context that is passed in rather than creating a local talloc
context. We also switch from using goto for return values, to doing
direct returns as soon as an error is detected, (which can be leak
free thanks to talloc).

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.
