When filtering the current search further with notmuch-search-filter,
wrap the current search in parens (if necessary).
This fixes unexpected behavior when the current search is
complex (like "(tag:this and date:one_week_ago..) or tag:that").
It's becoming a maintenance burden to do anything things with the
crypto glue code twice, once for 2.4 and once for 2.6. I don't have
any 2.4 version available to test on my development machine anymore,
so the 2.4 specific code paths are likely not very well tested.
The function notmuch_exit_if_unmatched_db_uuid is split from
notmuch_process_shared_options because it needs an open notmuch
database.
There are two exceptional cases in uuid handling.
1) notmuch config and notmuch setup don't currently open the database,
so it doesn't make sense to check the UUID.
2) notmuch compact opens the database inside the library, so we either
need to open the database just to check uuid, or change the API.
In the short term we need a way to get lastmod information e.g. for
the test suite. In the long term we probably want to add lastmod
information to at least the structured output for several other
clients (e.g. show, search).
This exposes the committed database revision to library users along
with a UUID that can be used to detect when revision numbers are no
longer comparable (e.g., because the database has been replaced).
This adds a new document value that stores the revision of the last
modification to message metadata, where the revision number increases
monotonically with each database commit.
An alternative would be to store the wall-clock time of the last
modification of each message. In principle this is simpler and has
the advantage that any process can determine the current timestamp
without support from libnotmuch. However, even assuming a computer's
clock never goes backward and ignoring clock skew in networked
environments, this has a fatal flaw. Xapian uses (optimistic)
snapshot isolation, which means reads can be concurrent with writes.
Given this, consider the following time line with a write and two read
transactions:
write |-X-A--------------|
read 1 |---B---|
read 2 |---|
The write transaction modifies message X and records the wall-clock
time of the modification at A. The writer hangs around for a while
and later commits its change. Read 1 is concurrent with the write, so
it doesn't see the change to X. It does some query and records the
wall-clock time of its results at B. Transaction read 2 later starts
after the write commits and queries for changes since wall-clock time
B (say the reads are performing an incremental backup). Even though
read 1 could not see the change to X, read 2 is told (correctly) that
X has not changed since B, the time of the last read. In fact, X
changed before wall-clock time A, but the change was not visible until
*after* wall-clock time B, so read 2 misses the change to X.
This is tricky to solve in full-blown snapshot isolation, but because
Xapian serializes writes, we can use a simple, monotonically
increasing database revision number. Furthermore, maintaining this
revision number requires no more IO than a wall-clock time solution
because Xapian already maintains statistics on the upper (and lower)
bound of each value stream.
- Make lib/notmuch.h the canonical location for the library versioning
information.
- Since the release-check should never fail now, remove it to reduce
complexity.
- Make the version numbers in notmuch.h consistent with the (now
deleted) ones in lib/Makefile.local
The files (test) scripts source (with builtin command `.`) provides
information which the scripts depend, and without the `source` to
succeed allowing script to continue may lead to dangerous situations
(e.g. rm -rf "${undefined_variable}"/*).
At the end of all source (.) lines construct ' || exit 1' was added;
In our case the script script will exit if it cannot find (or read) the
file to be sourced. Additionally script would also exits if the last
command of the sourced file exited nonzero.
News for notmuch-emacs-version usage in User-Agent header and
rename of function notmuch-version to notmuch-cli-version.
While at it, made some minor (consistency) punctuation changes
to make news to wiki conversion work as expected.
Previously we globally modified these variables, which tended to cause
problems for people using message-mode, but not notmuch-mua-mail, to
send mail.
User visible changes:
- Calling notmuch-fcc-header-setup is no longer optional. OTOH, it
seems to do the right thing if notmuch-fcc-dirs is set to nil.
- The Fcc header is visible during message composition
- The name in the mode line is changed, and no longer matches exactly
the menu label.
- Previously notmuch-mua-send-and-exit was never called. Either we
misunderstood define-mail-user-agent, or it had a bug. So there was
no difference if the user called message-send-and-exit directly. Now
there will be.
- User bindings to C-c C-c and C-c C-s in message-mode-map are
overridden. The user can override them in notmuch-message-mode-map,
but then they're on their own for Fcc handling.
This is to provide a clean way of overriding e.g. keybindings when
sending mail from notmuch.
This is needed in particular to allow somewhere to dynamically bind
certain message-mode variables which are not respected when buffer-local. See e.g.
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=21174
I marked the tests where I really couldn't understand the output as
broken. It could also be that I don't understand how directory removal
is supposed to work.
Try to narrow down what part of the code adds files and directories to
the queue(s) to be deleted.
Update one test. The output is slightly confusing, but I believe it is
correct, resulting from a directory being discovered but containing only ignored files.
Now that we have `notmuch-emacs-version' defined in notmuch emacs MUA
use that as a part of User-Agent: header to provide more accurate
version information when sending emails.
In case some incomplete installation of notmuch emacs MUA is used and
`notmuch-emacs-version' is defined as "unknown" then fall back to ask
version info from cli (as it used to be before this commit).
Requiring notmuch-version[.elc] and if that is missing setting
"fallback" notmuch-emacs-version (to "unknown") was moved from
notmuch.el to notmuch-lib.el as notmuch-mua.el (which provides
User-Agent: information) require's the latter.
The configure script chooses "python" if both python and python{2,3}
exist exists, so this could change the version of python used to run
the test suite.
The checking for ${NOTMUCH_PYTHON} in the test suite is arguably
over-engineering, since the configure step will fail if it can't find
it.
Show the current thread with a different filter (i.e., open messages
in the thread matching the new query).
Bound to 'l' for "limit".
Note that it is not the same as filter in search mode as it replaces
the existing query rather than ANDing with it (but it does keep the
thread-id part of the query).
Separate out a notmuch-show-goto-msg-id sub-function from
notmuch-show-apply-state. There should be no functional change but the
next patch will call the new function.
The CLI (and bindings) code should really be updated to use the new
status-code-returning versions. Here are some warnings to prod us (and
other clients) to do so.
Previously, we updated the database copy of a message on every call to
_notmuch_message_sync, even if nothing had changed. In particular,
this always happens on a thaw, so a freeze/thaw pair with no
modifications between still caused a database update.
We only modify message documents in a handful of places, so keep track
of whether the document has been modified and only sync it when
necessary. This will be particularly important when we add message
revision tracking.
It turns out that on certain systems like FreeBSD, c++filt is not
installed by default. It's basically OK if we fail the build in that
case, but what's really not OK is for the build to continue and
generate bad binaries.
Previously documentation was build automatically if sphinx/doxygen
executable were found. The switch is used to unconditionally disable
sphinx/doxygen detection and therefor, building of documentation
(including man pages).
Thanks to FreeBSD port maintainer Mikhail for report and the original
the original patch.
This is the right thing (TM) and also apparently fixes the build on
FreeBSD.
The second argument to notmuch-tag is now called tag-changes, but the
documentation for notmuch-before-tag-hook and notmuch-after-tag-hook
still used the old argument name `tags'. This resulted in broken hooks
when following the documentation.
The mark read code for tree mode did not get updated in the recent
changes. This updates it to match. Since the user can customize the
mark read logic we just call the show logic in the message pane.
This is supposed to help build on systems like MacOS with different
conventions for naming shared libraries. We have already computed the
relevant names, so doing it again in ruby seems like a bad idea.
