make-process is a new function introduced in Emacs 25, which provides
greater control over process creation. Crucially, it allows
separately redirecting stderr directly to a buffer, which allows us to
avoid needing to use the shell to redirect to a temporary file in
order to correctly distinguish stdout and stderr.
* notmuch-lib.el: Use make-process when it is available; fall back to
the previous method when not.
Load subprocess error output to a string in the callers, and propagate
the error messages as a string parameter instead of a path to file
names.
Required to be able to avoid using temporary files for subprocess
error output.
* notmuch-lib.el: Update notmuch-check-async-exit-status,
notmuch-check-exit-status: accept an err parameter instead of
err-file; shift the responsibility of loading error messages from
files up the call stack.
The queries "" and "*" are special cased in the notmuch library to
match all messages, but only if they're the entire query. They can't
be combined with other queries, such as "* AND foo", in which case
they "leak" down to the Xapian query parser.
Notmuch show and tree buffers inadvertently combine the thread query
with said special queries, causing incorrect collapsing of
messages. Handle the special queries specially. We already do a
similar thing in notmuch-search-filter.
A leading / in paths in a .gitignore file matches the beginning of the
path, meaning that for patterns without slashes, git will match files
only in the current directory as opposed to in any subdirectory.
Prefix relevant paths with / in .gitignore files, to prevent
accidentally ignoring files in subdirectories and possibly slightly
improve the performance of "git status".
We have a steady trickle of people using notmuch-emacs from melpa with
distro packages of notmuch, and then being confused when it doesn't
work. Try to warn people what a foot-gun this is; this commentary
should be copied to the melpa web site.
There are some cases like remote usage where this might cause
problems, but those users can easily customize the variable. The
inconvenience seems to be outweighed by the security benefit for most
users.
Since the error field is unused by the emacs front end, no changes are
needed other than bumping the format version number.
As it is, this is a bit overengineered, but it will reduce duplication
when we support gmime 3.0
Emacs' major modes can facilitate navigation in their buffers by
supporting Imenu. In such major modes, launching Imenu (M-x imenu)
makes Emacs display a list of items (e.g., function definitions in a
code buffer). Selecting an item from this list moves point to this
item.
This patch adds Imenu support to both notmuch-show and notmuch-search
buffers:
* in notmuch-show, Imenu will present a list of all messages in the
currently visible thread;
* in notmuch-search, Imenu will present a list of all messages in the
search buffer.
Previously notmuch tree did not specify the format-version when
calling notmuch. This meant that when the structured output was
slightly changed (in commit 14c60cf168)
stash filename broke. This fixes this breakage by specifying the
format-version.
Adjusted notmuch-crypto gpg call-process function to respect
the GPG program set by the EasyPG epg-gpg-program variable.
This is to correct a problem observed on NixOS where only gpg2 is
installed by default. The Notmuch Emacs frontend fails when trying to
access someone's key to verify their signature when it cannot find the
GPG binary.
This backports the fix from emacs master (commit
77bbca8c82f6e553c42abbfafca28f55fc995d00) to notmuch-emacs to wrap
long headers.
This fixes the test introduced in the previous changeset.
With the mailto: handling in notmuch-emacs-mua, we can update the
desktop file to advertize we can be set as the default application to
handle email. While at it, add GenericName and Comment to be more
informative.
With --hello, notmuch-emacs-mua will run (notmuch) if mailto: url is
not given.
Gnus seems to display application/zip and application/tar by
default. This doesn't seem desirable so we override it.
We only override if the user has not customized
mm-inline-override-types themselves.
Fix the deprecation warning:
In notmuch-maildir-fcc-make-uniq-maildir-id:
emacs/notmuch-maildir-fcc.el:279:53:Warning: ‘system-name’ is an obsolete
variable (as of 25.1); use (system-name) instead
I've used (system-name) since at least 2011, so it must have been
around quite a while.
We now have several customizable options for address completion. There
is a customize group notmuch-address but it only contains one of these
options. Add all the others, and make it part of the notmuch customize
group.
This allows the user to save the address hash so that it is much
faster for the first completion after a restart. This defaults to off
as there are privacy implications to saving this information.
The code tries hard to avoid overwriting the wrong file. It also notes
if changes have been made to any of the relevant user settings, so
that the user does not get surprising results (i.e., outdated options
being used). Finally it stores some version information so that is
easy for us to update the format of the save file.
This makes the code access notmuch-address-full-harvest-finished via a
helper function, notmuch-address--harvest-ready. Later we will use
this to check whether we can load the harvest instead of regenerating
it.
There is really no need to have a separate install target for the
desktop file. Just install the desktop file with emacs, with a
configure option to opt out.
If the --hello parameter is given, display the notmuch hello buffer
instead of the message composition buffer if no message composition
parameters are given.

Some of the recent changes to the emacs code have used functions
introduced in emacs 24. The functions used are read-char-choice and
setq-local. This changeset adds a file notmuch-compat.el which
contains compatibility functions so that it should work on emacs
23.
Note, since these functions are taken almost unchanged from the emacs
source they are copyright the Free Software Foundation, and the header
in the file reflects that.
Provide functionality to resume editing a message previously saved with
notmuch-draft-save, including decoding the X-Notmuch-Emacs-Secure
header.
Resume gets the raw file from notmuch and using the emacs function
mime-to-mml reconstructs the message (including attachments).
'e' is bound to resume a draft from show or tree mode.
This provides initial support for postponing in the emacs frontend;
resuming will follow in a later commit. On saving/postponing it uses
notmuch insert to put the message in the notmuch database
Current bindings are C-x C-s to save a draft, C-c C-p to postpone a
draft (save and exit compose buffer).
Previous drafts get tagged deleted on subsequent saves, or on the
message being sent.
Each draft gets its own message-id, and we use the namespace
draft-.... for draft message ids (so, at least for most people, drafts
are easily distinguisable).
We want to use "e" for editting postponed messages in show, and in
tree view, so remove the binding for the function which does
(In message pane) Activate BUTTON or button at point
This hook can be used to update the message based on the results of
address completion. For example using message-templ or gnus-alias to set
the From address based on the To address just completed.
The post-completion command is added to the notmuch-company backend to
ensure that the hook is also called company completion is started
without going through notmuch-address-expand-name. See the docstring of
`company-backends' for more information.
This makes replying to a message in tree view, use the decrypted state
from the message pane if it is open. Previously it just used the
global decryption state from notmuch-crypto-process-mime.
In particular if notmuch-crypto-process-mime is nil, and the user
views the messages (which doesn't decrypt), toggles decryption in the
message pane, and then replies, the reply will be decrypted.
This makes $ in the tree pane toggle decryption in the message
pane. Without this the user can only decrypt the message pane by
switching to it, or by setting decryption on globally by setting
notmuch-crypto-process-mime to t.
The notmuch-tag-flagged, notmuch-search-flagged-face and
notmuch-crypto-part-header faces defaulted to "blue", which is nearly
unreadable when a dark background is in use. This is addressed by using
"LightBlue1" for dark backgrounds.
As a side effect, these faces are now no-op definitions for grayscale or
mono displays.
The normal tag commands in search mode tag the all threads meeting the
region when called interactively. This makes them do the same when
called non-interactively. This is a change in the api.
This makes tag changes appear in the message pane as well as in the
tree window.
Note that the message pane is reloaded each time a message is viewed
so the tags shown in the message pane can still be different from
those in the tree window. Usually this will just be that the tag
change is still shown as a change (strikethough underline etc) in the
tree window, and are shown after the change in the message
pane. However, if something else updates the database then the tags
shown can be genuinely different.
The command notmuch-interesting-buffer has got out of date -- it
doesn't mention notmuch-tree, and it still refers to message-mode not
notmuch-message-mode. Update both of these.
This fixes the bug that notmuch-cycle-notmuch-buffers does not include
notmuch-tree or notmuch-message-mode buffers in its cycling.
notmuch-show--build-buffer now queries a list of queries built by the
former. This simplifies the logic. It also provides an easy place to
experiment with alternate sets of queries for given notmuch-show-*
variables (e.g. users can use advice-add to do so in a surgical way).
This commit expands docstrings for notmuch-fcc-dirs and
notmuch-maildir-fcc-with-notmuch-insert to describe how quoted strings
are processed and make the ability to configure sent folders containing
whitespace more discoverable.
In commit 2a7b11b064 the default value
for notmuch-search-line-faces was changed so that it didn't match the
specification in the corresponding defcustom. This meant that it was
difficult for the user to customize this variable as they got a type
mismatch error.
Note anyone who had already customised this variable would not see
this bug as their customisation would match the defcustom.
We can't use c-u = as some of the notmuch-show refresh function
already uses that. This is a global keybinding for a relatively
infrequent function but M-= seems unlikely to cause conflicts.
notmuch-refresh-all-buffers calls each buffer's major mode specific
refresh function using the generic notmuch-refresh-this-buffer function.
Since the earlier changesets have stopped the refresh functions from
forcing the buffers to be redisplayed this can refresh buffers that
are not currently displayed without disturbing the user. This is very
useful for silent async background updating the emacs display when new
mail is fetched.

This updates all windows displaying a notmuch-show buffer when the
buffer refresh function is called.
Each window displaying a notmuch-show buffer has its own currently
displayed message based on the (point) location. We store the state
of all displayed windows when refreshing a notmuch-show buffer and
re-apply the current shown message (point) for all windows.
Implementation note: Each window has it's own (point) value, besides
the buffer's (point) value. Sometimes these values are identical like
in the case where a single window displays a buffer. When multiple
windows display a buffer, (point) returns each window's specific value.
What we are storing in this changeset is the window values not the
buffer point values. The buffer's point is returned only if no window
is displaying the buffer, a case we do not care about here.

There's no reason to completely kill a buffer while refreshing its
search results because the buffer name is constant between refreshes
(based on the search query), only its contents may change and notmuch
search kills all local variables, so it's safe to reuse.
Reusing the same buffer also makes it possible to do things like
refreshing a buffer which is not focused or even not shown in any
window - this will be used in the next commits to add auto-refresh
capabilities to all existing notmuch buffers + a function to call
after syncing mail to refresh everything.

If no-display is non-nil when calling notmuch-search then do not force
the search buffer to be displayed.

Make the notmuch-hello refresh function (notmuch-hello-update) not
force the buffer to be displayed. All the callers call it when the
buffer is already displayed so it will only affect non-interactive
callers. Since it is just a trivial wrapper of notmuch-hello anyone
who wants to force the buffer to be displayed should just call
notmuch-hello.
If an encrypted multipart message is received which contains html and
notmuch-multipart/alternative-discouraged is set to discourage "text/plain",
any encrypted parts are not decrypted during generation of the reply
text. This fixes that problem by making sure notmuch-mua-reply does
that.
notmuch jump allows the user to specify a key sequence rather than
just a single key for its bindings. However, it doesn't show what has
already been typed so it can be difficult to see what has
happened. This makes each key press appear, and the jump menu reduce
to the possible follow up keys.
We also bind backspace (emacs symbol DEL) to go back up a level in the
subjumpmaps, and to exit from the top level.
In commit 297d091e1c the key for
switching to the reverse keymap was changed from r to k but the
docstring for the defcustom was not updated. This changeset updates
the documentation to match.
This seems to fix a problem with emacs 25 creating partial buttons by
calling n-s-b-l with a region that does not include the whole button.
I'm not 100% sure it's legit to act outside the region passed by
jit-lock, but goto-address-fontify-region (where I borrowed the code
from) already does this, so this patch to not make things worse.
Emacs message-send seems to ignore a secure mml tag anywhere except at
the start of the body, and it must be followed by a newline. Since
this is almost certainly not desired we check for it, and require user
confirmation before sending.
As the setup before message-send or message-send-and-exit is getting
more complicated it is convenient to unify the two correspoinding
notmuch functions.
This commit adds a common message-send function for message-send and
message-send-and-exit. At the moment the overlap is small, but the
message-send function will get more complex.
The current code for address completion takes the list of possible
completions (whether generated internally or externally), makes the
first match the initial value for the completion, and puts all the
others (but not the first match) into the possible completions.
This has the nice effect that the <down> key takes you immediately to
the next completion (whereas if the first match were included in the
possible completions it would take you to the first match
again).
However, it has two side effects. First, once you have completed to
the full match you find it says and try completing again you get told
"no match" not "sole completion". Secondly, if you delete some of the
text and try completing you don't get the first match as an option.
This tries to get round most of these problems by including the full
list of possible completions, but with the first match moved to the
very end of the list.
Currently, by default k invokes the tag-jump menu, and following it by
r invokes the reverse tag change jump menu. This is awkward to type
(e.g. k r u for undoing a -unread change). This changes it so that k
followed by k invokes the reverse menu. We make the key for the
reverse map a variable as that makes it possible for a user to
change it by editing their .emacs file.
This tweaks the keybindings in tree-mode. It make b do bounce/resend
matching show-mode. Since b was already bound to scroll message pane
back, we now use backspace for that.
This means space/backspace scroll the message pane forwards/backwards,
and page-up/page-down scrolls the tree pane forwards/backwards.
Commit d25d33ff cleaned up some of the tag face code. However, for the
face notmuch-tag-deleted it used the test
((class color) (supports :strike-through))
to decide whether to use red strikethrough or inverse-video (emacs in
a terminal typically doesn't support red strikethrough, but in X it does).
However, it seems that test often returns true even though red
strikethrough is not supported. This breaks the tag update code -- the
wrong thing is displayed to the user.
Thus we make the test explicitly more specific, changing the test to
((class color) (supports :strike-through "red"))
j is in the global notmuch keymap bound to notmuch jump. In tree-mode
it makes sense to close the message pane first (otherwise the new
search runs in the small top pane of tree-mode).
This stops the (usually incorrect) sigstatus and encstatus buttons
appearing when replying in emacs, and updates the test suite to match.
Overriding the status button functions is a little unusual but much
less intrusive than passing an argument all the way down the call
chain. It also makes it clear exactly what it does.
We also hide the application/pgp-encrypted part as it can only contain
"Version: 1". We do this in notmuch show, which means it also happens
when replying.
Previously if notmuch-wash-wrap-lines-length was set then all messages
would be wrapped at this value (or window-width if that is
smaller). This was done regardless of the message's depth in a thread --
for example, if the n.w.w.l.l is 80 and the messages depth is 20
(so indented 20 by default) the messages text only got 60 characters
of space.
This commit changes that so a message always gets the full n.w.w.l.l
of width regardless of its indentation (unless that goes over
window-width of course).
This allows the user to override the mime-type of a part in the show
buffer. This takes the simple option of displaying the part with the
specified mime-type in its own buffer (in view mode). This avoids
further complicating the part handling code.
Bound to ". m" (i.e., m in the part map). Then the user can either
enter a mime-type (with completion to all mime types that mailcap (and
thus notmuch) knows about, or press return for the default choice of
text/plain.
With all the preparation it is now simple to add the actual insert
code. Since insert can fail for many reasons we let the user decide
interactively deal with it.
We modify test-lib.el to set file fcc, so that all the old tests and
emacs_fcc_message from test-lib.sh still work
We will need our own local copy of message-do-fcc so this commit just
copies the code straight from message.el so that it is easier to see
our local changes coming in the next commit.
We move some code around in preparation for the use of notmuch
insert. In particular, we move the check for a valid maildir for the
fcc to when the message is sent rather than when the fcc header is
inserted. The main motivation is consistency with the insert version
(coming later) where we cannot check the validity until send.
We allow the user some chance to correct the header; the choice here
is intended to be consistent with the insert version to come.
This function prints diagnostic information in the event of an
error. However, one of the callers has an optional :stdin-string
keyword argument. This causes the error printing routine to error
itself.
Rather than reach notmuch-check-exit-status about the possible keyword
arguments (currently only one but could be more in the future) this
commit just tells notmuch-check-exit-status how to print non-string arguments.
This commit makes two changes. The first allows the user to override
an external completion method with the internal notmuch address based
completion for an individual buffer.
Secondly, if the user has company-mode enabled then it sets up company
mode (based on internal completion) but disables the automatic timeout
completion -- the user can still activate it in when desired with
standard company commands such as company-complete.
This commit lets the user customize the address completion. It makes
two changes.
The first change controls whether to build the address completion list
based on messages you have sent or you have received (the latter is
much faster).
The second change add a possible filter query to limit the messages
used -- for example, setting this to date:1y.. would limit the
address completions to addresses used in the last year. This speeds up
the address harvest and may also make the search less cluttered as old
addresses may well no longer be valid.
The User-Agent: header can be fun and interesting, but it also leaks
quite a bit of information about the user and their software stack.
This represents a potential security risk (attackers can target the
particular stack) and also an anonymity risk (a user trying to
preserve their anonymity by sending mail from a non-associated account
might reveal quite a lot of information if their choice of mail user
agent is exposed).
This change also avoids hiding the User-Agent header by default, so
that people who decide they want to send it will at least see it (and
can edit it if they want to) before sending.
It makes sense to have safer defaults.
Previously notmuch-wash made the width of the text (approximately) the
window-width minus the depth in thread. This is correct for the
default indentation of 1 per message depth, but is incorrect for any
other setting of notmuch-show-indent-messages-width.
As notmuch-show-indent-messages-width is customisable, and notmuch-tree
sets it to zero to avoid indenting messages in the message pane, this
bug can show up in real use.
Two of the tests had to be updated: when
notmuch-show-indent-messages-width is 0, then the new (correct) word
wrapping happens later, when notmuch-show-indent-messages-width is 4,
then the new word wrapping happens sooner.
The two new faces (notmuch-search-flagged-face and
notmuch-search-unread-face) make it easier to find the relevant face by
customizing notmuch-faces. I plan to do the same to the other alists of
faces found elsewhere.
Previously if a marking read tag change (i.e., removing the unread
tag) failed for some reason, such as a locked database, then no more
mark read tag changes would be attempted in that buffer.
This handles the error more gracefully. There is not much we can do
yet about dealing with the error itself, and marking read is probably
not important enough to warrant keeping a queue of pending changes or
anything.
However this commit changes it so that
- we do try and make future mark read tag changes.
- we display the tag state correctly: i.e. we don't display the tag as
deleted (no strike through)
- and since we know the tag change failed we can try to mark this
message read in the future. Indeed, since the code uses the
post-command hook we will try again on the next keypress (unless the
user has left the message).
We indicate to the user that these mark read tag changes may have
failed in the header-line.
