4eb151e26c emacs: do not put quoted reply in primary selection
In current emacs (24.3) select-active-regions is set to t by
default. The reply insertion code sets the region to the quoted
message to make it easy to delete (kill-region or C-w). These two
things combine to put the quoted message in the primary selection.

This is not what the user wanted and is a privacy risk (accidental
pasting of the quoted message). We can avoid some of the problems
by let-binding select-active-regions to nil. This fixes if the
primary selection was previously in a non-emacs window but not if
it was in an emacs window. To avoid the problem in the latter case
we deactivate mark.

One key test (which fails under many simpler "fixes") is: open emacs
24.3 with notmuch, open 2 windows (viewing different notmuch buffers),
highlight some text in one, and then reply to a message in the
other. In many of my earlier attempts to fix this big this test fails.

9838fe8e16 emacs: tree: use remap for the over-ridden global bindings
Following a suggestion by Austin in id:20130915153642.GY1426@mit.edu
we use remap for the over-riding bindings in pick. This means that if
the user modifies the global keymap these modifications will happen in
the tree-view versions of them too.

[tree-view overrides these to do things like close the message pane
before doing the action, so the functionality is very close to the
original common keymap function.]

remaps are a rather unusual keymap consisting of "first key" 'remap
and then "second-key" the remapped-function. Thus we do the

9d0174b11c emacs: help: remove duplicate bindings
If the user (or a mode) overrides a keybinding from the common keymap
in one of the modes then both help lines appear in the help screen
even though only one of them is applicable.

Fix this by checking if we already have that key binding. We do this
by constructing an list of (key . docstring) pairs so it is easy to
check if we have already had that binding. Then the actual print help
routine changes these pairs into strings "key \t docstring"

The routines that construct the help page in notmuch-lib rely on
match-data being preserved across some fairly complicated code. This
is currently valid but will not be when this series is finished. Thus
place everything between the string-match and replace-match inside a

a5ecdf390e emacs: help: check for nil key binding
A standard way to unset a key binding is local-unset-key which is equivalent to
  (define-key (current-local-map) key nil)

Currently notmuch-help gives an error and fails if a user has done this.

To fix this we only add a help line if the binding is non-nil.

96c0ce28f8 emacs: Fix search tagging races
This fixes races in thread-local and global tagging in notmuch-search
(e.g., "+", "-", "a", "*", etc.).  Previously, these would modify tags
of new messages that arrived after the search.  Now they only operate
on the messages that were in the threads when the search was
performed.  This prevents surprises like archiving messages that
arrived in a thread after the search results were shown.

This eliminates `notmuch-search-find-thread-id-region(-search)'
because these functions strongly encouraged racy usage.

This fixes the two broken tests added by the previous patch.

6661206381 emacs: minimal change to load notmuch-tree by default
We want to load notmuch-tree when notmuch is loaded, so include it as
a require in notmuch.el. To avoid circular dependency we need to move
one keybinding from notmuch-tree.el to notmuch.el: it makes sense for
it to be defined there anyway.

Since tree is now loaded by default there is no need to print a
message when it is loaded.

9f9a63c863 emacs: Add a space after completed tag operations
Previously, when a user fully completed a tag operation, they had to
press space to begin entering another tag operation.  This is
different from, say, shell file name completion, which typically
inserts a space after an unambiguous completion under the assumption
that the user will want to enter more input.

This patch tweaks `notmuch-read-tag-changes' to act more like shell
file name completion: after an unambiguous tag completion, it now
inserts a space, ready and waiting for another tagging operation from
the user.  This is backwards-compatible with old habits, since there's
no harm in putting an extra space.

22172daa17 emacs: Use interactive specifications for tag changes in search
This is similar to the previous commit, but applies to search.

Search is somewhat more complicated because its tagging operations can
also apply to a region.  Hence, this lifts interactive prompting into
a helper function.  This also takes advantage of the new ability to
provide a prompt to distinguish tagging a single thread from tagging a
region of threads.

47792533b3 emacs: Use interactive specifications for tag changes in show
This modifies all tagging operations in show to call
`notmuch-read-tag-changes' in their interactive specification to input
tag changes, rather than depending on lower-level functions to prompt
for tag changes regardless of their calling context.

Besides being more Elispy and providing a more consistent programmatic
API, this enables callers to provide two call site-specific pieces of
information: an appropriate prompt, and the set of visible tags.  The
prompt lets us differentiate * from +/-.  Providing visible tags
enables a more consistent user experience than retrieving the
(potentially different) tags from the database, and avoids a
round-trip to the CLI and database.

0f8d5b6b0e emacs: Take prompt and current tags in `notmuch-read-tag-changes'
This modifies the interface of `notmuch-read-tag-changes' to take an
optional prompt string as well as a list of existing tags instead of a
query.  This list of tags is used to populate the tag removal
completions and lets the caller compute these in a more
efficient/consistent manner than performing a potentially large or
complex query.  This patch also updates the sole current caller of
`notmuch-read-tag-changes'.

440b8065c9 emacs: Fix misuse of `notmuch-tag'
The calling convention for `notmuch-tag' changed in commit 97aa3c06 to
take a list of tag changes instead of a &rest argument, but the call
from `notmuch-search-tag-all' still passed a &rest argument.  This
happened to work for interactive calls because tag-changes would be
nil, so the `apply' call would pass only the query string to
`notmuch-tag' and simply omit the &optional tag-changes argument.

c1221dd65a emacs: Improve interactive use documentation
This improves the function documentation for many interactive
commands, either by improving their documentation string where the
improvement also makes sense for programmatic use or by adding a
'notmuch-doc property where it doesn't.

For nearly all commands that support a prefix argument, this adds a
'notmuch-prefix-doc property to document their prefixed behavior This
omits prefix documentation for a few commands where I thought the
prefixed behavior was too obscure (or too complex to fit in one line).

fad4f21cb7 emacs: Support overriding help and describing prefix action
Traditionally, function documentation strings are intended primarily
for programmers, rather than users.  They're written from the
perspective of calling the function, not interactively invoking it.
They're only ever displayed along with the function prototype (and
often refer to argument names).  And built-in help commands like
`describe-bindings' show the name of the command, not its
documentation.

The notmuch help system is like `describe-bindings', but tries to be
more user-friendly by displaying documentation strings, rather than
Elisp command names.  For most commands, this is fine, but for some
the "programmer description" is inappropriate for interactive use.
This is particularly noticeable for commands that take an optional
prefix argument.

This patch adds support for two symbol properties: notmuch-doc and
notmuch-prefix-doc, which let a command override its interactive
documentation and provide separate documentation for its prefixed
invocation.  If notmuch-prefix-doc is present, we add an extra line to
the help giving the prefixed key sequence along with the documentation
for the prefixed command.

Like `notmuch-mua-new-forward-message', this is meant to be invoked
programmatically by something that can provide a reasonable query
string.

In fact, `notmuch-mua-new-reply's interactive specification didn't

interactively.

fd656d7683 emacs: Move ?, q, s, m, =, and G to the common keymap
The only user-visible effect of this should be that "G" now works in
show mode (previously it was unbound for no apparent reason).

This shared keymap gives us one place to put global commands, which
both forces us to think about what commands should be global, and
ensures their bindings can't diverge (like the missing "G" in show).

The lazy part handler had a bug that it allowed the button to be

properties at point rather than from the button.

In almost all cases this didn't matter as as point had the same text
properties as the button. However, it is a bug and did cause incorrect
behaviour in some cases: see id:87txhz14z6.fsf@qmul.ac.uk for details.

4ceeaf8038 emacs: fix notmuch-mua-reply point placement when signature involved
When composing a reply, notmuch-mua-reply attempts to  cite the
the original message by inserting it before the user signature, if
one is present. The existing method used to search the signature
separator backward from the end of the buffer and then move one
line up. In case of variable `message-signature-insert-empty-line'
being nil this caused point to go to the beginning of
'--text follows this line--'
separator line, and citation was inserted there.
This change checks the value of `message-signature-insert-empty-line'
and doesn't move point if that is nil. Additional narrowing to
the body region ensures that point never goes to the separator line
(or beyond).
`message-signature-setup-hook' or `message-setup-hook' may already have
added some other content to the message body, therefore using simply
(message-goto-body) to move point to the beginning of body might lead
to unexpected results.

Original patch from "Geoffrey H. Ferrari", continued with iterations
from Jani and Mark.

In reply, insert quotable parts using notmuch-show-insert-bodypart
instead of calling notmuch-mm-display-part-inline directly to render
the quoted parts as they are rendered in show view.

We use a temp buffer to not leak text properties from the show
renderer into the reply. This way we also don't need to worry about
narrowing or point placement. Credits to Mark Walters
<markwalters1009@gmail.com> and Austin Clements <amdragon@MIT.EDU> for
getting this part straight.

pretty printed output of icalendar-import-buffer rather than the ugly
raw vcalendar.

viewer rather than just offering to save the part.

(broke) this. This patch stores the calculated mime-type with the part
and changes the attachment part handlers can use it instead.

d0bd88f06d emacs: show: implement lazy hidden part handling
This adds the actual code to do the lazy insertion of hidden parts.

We use a memory inefficient but simple method: when we come to insert
the part if it is hidden we just store all of the arguments to the
part insertion function as a button property. This means when we want
to show the part we can just resume where we left off.

One thing is that we can't tell if a lazy part will produce text until
we try to render it so when unhiding a part we check to see if it
rendered; if not we invoke the default part handler (e.g. an external
viewer).

Also, we would like to insert the lazy part at the start of the line
after the part button. But if this line has some text properties
(e.g. the colours for a following message header) then the lazy part
gets these properties. Thus we start at the end of the part button
line, insert a newline, insert the lazy part, and then delete the
extra newline at the end of the part.

490b02345e emacs: show: modify the way hidden state is recorded.
Previously, whether a part was hidden or shown was recorded in the
invisibility/visibility of the part overlay. Since we are going to
have lazily rendered parts with no overlay store the hidden/shown
state in the part button itself.

Additionally, in preparation for the invisible part handling move the
actual hiding of the hidden parts to insert-bodypart from
create-part-overlays.

Finally, we will need to know whether a part-insertion has done
anything (it won't if the invisible part cannot be displayed by emacs)
so we slightly rejig the code order in
notmuch-show-toggle-part-invisibility to make it easier for the
function to set an appropriate return value.

702210b84d emacs: show: move the insertion of the header button to the top level
Previously each of the part insertion handlers inserted the part
button themselves. Move this up into
notmuch-show-insert-bodypart. Since a small number of the handlers
modify the button (the encryption/signature ones) we need to pass the
header button as an argument into the individual part insertion
handlers. However, the declared-type argument was only used for the
text for the part buttons we can now omit it.

The patch is large but mostly simple. The only things of note are that
we let the text/plain handler applies notmuch-wash to the whole part
including the part button. In particular, notmuch-wash removes leading
blank lines from a text/plain part, but since the button is counted as
part of the part this does not happen with text/plain buttons that
have a button. This is probably a bug in notmuch-wash but changing it
does make several tests fail (that rely on this blank line) so, for
the moment, keep the old behaviour.

88cce8c6a4 emacs: Fix "no such file or directory" error
Occasionally, when the user killed the search buffer when the CLI
process was still running, Emacs would run the
notmuch-start-notmuch-sentinel sentinel twice.  The first call would
process and delete the error output file and the second would fail
with an "Opening input file: no such file or directory, ..." error
when attempting to access the error file.

Emacs isn't supposed to run the sentinel twice.  The reason it does is
rather subtle (and probably a bug in Emacs):

1) When the user kills the search buffer, Emacs invokes
kill_buffer_processes, which sends a SIGHUP to notmuch, but doesn't do
anything else.  Meanwhile, suppose the notmuch search process has
printed some more output, but Emacs hasn't consumed it yet (this is
critical and is why this error only happens sometimes).

2) Emacs gets a SIGCHLD from the dying notmuch process, which invokes
handle_child_signal, which sets the new process status, but can't do
anything else because it's a signal handler.

3) Emacs returns to its idle loop, which calls status_notify, which
sees that the notmuch process has a new status.  This is where things
get interesting.

3.1) Emacs guarantees that it will run process filters on any
unconsumed output before running the process sentinel, so
status_notify calls read_process_output, which consumes the final
output and calls notmuch-search-process-filter.

3.1.1) notmuch-search-process-filter checks if the search buffer is
still alive and, since it's not, it calls delete-process.

3.1.1.1) delete-process correctly sees that the process is already
dead and doesn't try to send another signal, *but* it still modifies
the status to "killed".  To deal with the new status, it calls
status_notify.  Dun dun dun.  We've seen this function before.

3.1.1.1.1) The *recursive* status_notify invocation sees that the
process has a new status and doesn't have any more output to consume,
so it invokes our sentinel and returns.

3.2) The outer status_notify call (which we're still in) is now done
flushing pending process output, so it *also* invokes our sentinel.

This patch addresses this problem at step 3.1.1, where the filter
calls delete-process, since this is a strange and redundant thing to
do anyway.

Previously, when the user killed the search buffer before the CLI
search process had completed, we would report the signal sent by Emacs

error exits if the process buffer is still live.  We still report
stderr output regardless in case stderr output was relevant to why the
user killed the search buffer (such as a wrapper script being stuck).

109a0355d6 emacs: Fix applying stickiness to the :notmuch-part property
Previously, we simply called pushnew to add :notmuch-part to the
front-sticky and rear-nonsticky text property lists.  This works if
these are nil or lists, but they can also have the value t, meaning
that all properties are front-sticky/rear-nonsticky.  In this case,
pushnew will signal an error because t is not a list.  We never set
these properties to t ourselves, but since we apply these property
changes over arbitrary renderer output, we have to deal with this
possibility.

89efd5717a emacs: Use streaming S-expr parser for search
In addition to being the Right Thing to do, this noticeably improves
the time taken to display the first page of search results, since it's
roughly an order of magnitude faster than the JSON parser.
Interestingly, it does *not* significantly improve the time to
completely fill a large search buffer because for large search
buffers, the cost of creating author invisibility overlays and
inserting text (which slows down with more overlays) dominates.
However, the time required to display the first page of results is
generally more important to the user experience.

b89ffba301 emacs: Streaming S-expression parser
This provides the same interface as the streaming JSON parser, but
reads S-expressions incrementally.  The only difference is that the
`notmuch-sexp-parse-partial-list' helper does not handle interleaved
error messages (since we now have the ability to separate these out at
the invocation level), so it no longer takes an error function and
does not need to do the horrible resynchronization that the JSON
parser had to.

Some implementation improvements have been made over the JSON parser.
This uses a vector instead of a list for the parser data structure,
since this allows faster access to elements (and modern versions of
Emacs handle storage of small vectors efficiently).  Private functions
follow the "prefix--name" convention.  And the implementation is much
simpler overall because S-expressions are much easier to parse.

edc740857f emacs: Bind MIME part commands to "." submap
Since the part commands are no longer tied to a button, but can be
applied with point anywhere within a part, bind the part commands
keymap to "." everywhere in the show buffer.  This lets you save or
view parts without having to navigate to the part button, and is
particularly useful for parts that have no button.

This removes the un-prefixed MIME part commands from the part button
keymap, but that's okay because those clashed in annoying ways with
show buffer bindings like "s" for search.  RET on part buttons is
unaffected, which is the most important part button binding.

1546387d72 emacs: Simplify MIME part command implementation
This unifies the part button actions and the underlying part action
functions into single interactive command that simply applies to the
part containing point using the just-added part p-list text property
instead of button properties.  Since all part actions can be performed
by applying the appropriate mm function to an mm-handle, this patch
abstracts out the creation of mm handles, making the implementations
of the part commands trivial.  This also eliminates our special
handling for part save in favor of using the appropriate mm function.

This necessarily modifies the way we handle the default part button
action, but in a way that does not change the meaning of the
notmuch-show-part-button-default-action defcustom.

Since these commands are no longer specific to buttons, this patch
eliminates the extra metadata stored with each button.  This also
eliminates one rather special-purpose macro for a collection of
general purpose part handling utilities.

e7ade21d56 emacs: Fix trimming regexp in notmuch-check-exit-status
For such a simple regexp, this was broken in a very complicated way.

The intent was to strip the newline (and potentially other whitespace)
off the end of the error string so there wasn't an extra newline in
the error signal.  However, the regexp was deeply dependent on the
active syntax table and the subtleties of $.  We didn't notice this
because all notmuch major modes put ?\n in the whitespace class, which
makes this behaved as intended: the "\\s " matches all newlines, but
by matching the newline character, causes the $ *not* to match
*except* where it matched the empty string at the very end of the
string, which was not followed by a newline.

However, if the syntax table declares ?\n to be non-whitespace
(lisp-mode declares it as endcomment, and is likely to be the mode
you're in when testing functions), then this regexp behaves completely
differently, matching trailing spaces at the end of every line within
the string.

The solution is to say what we mean for whitespace *and* to switch
from $ to \', which matches only the end of the string, rather than
the end of each line.  Both are necessary or this will strip away
interior newlines, which is not what we want.

d4940d4716 emacs: Don't override mm-show-part in notmuch-show-view-part
Previously, notmuch-show-view-part overrode the function binding of
mm-show-part to redirect it to notmuch-show-save-part to get notmuch's
default file name handling in case mm-display-part decided to fall
back to saving the part.  In addition to being messy, this depended on
the now-deprecated dynamic binding behavior of flet.

This patch removes the mm-show-part override in favor of passing the
file name in to mm-show-part the way it expects, so we get its default
file name handling.  It's not clear why we didn't do this before;
mm-show-part has supported default file names since at least Emacs

68720286eb emacs: Compute build dependencies to fix byte compile issues
Previously, we simply byte compiled each Elisp source file
independently.  This is actually the wrong thing to do and can lead to
issues with macros and performance issues with substitutions because
1) when the byte compiler encounters a (require 'x) form, it will load
x.elc in preference to x.el, even if x.el is newer, and as a result
may load old macro and substitution definitions and 2) if we update a
macro or substitution definition in one file, we currently won't
re-compile other files that depend on the file containing the
definition.

This patch addresses these problems by computing make dependency rules
from the (require 'x) forms in the Elisp source files, which we inject
into make's dependency database.
