1 Notmuch 0.12 (2012-xx-xx)
2 =========================
9 "notmuch reply" has gained the ability to create a reply template
10 for replying just to the sender of the message, in addition to reply
11 to all. The feature is available through the new command line option
12 --reply-to=(all|sender).
16 Tags can be automatically excluded from search results by adding them
17 to the new 'search.exclude_tags' option in the Notmuch config file.
19 This behaviour can be overridden by explicitly including an excluded
20 tag in your query, for example:
22 notmuch search $your_query and tag:$excluded_tag
24 Existing users will probably want to run "notmuch setup" again to add
25 the new well-commented [search] section to the configuration file.
27 For new configurations, accepting the default setting will cause the
28 tags "deleted" and "spam" to be excluded, equivalent to running:
30 notmuch config set search.exclude_tags deleted spam
32 Mail store folder/file ignore
34 A new configuration option, `new.ignore`, lets users specify a
35 ;-separated list of file and directory names that will not be
36 searched for messages by "notmuch new".
43 The Emacs interface has, with the new CLI support, gained the
44 ability to reply to sender in addition to reply to all. In both show
45 and search modes, 'r' has been bound to reply to sender, replacing
46 reply to all, which now has key binding 'R'.
48 More flexible and consistent tagging operations
50 All tagging operations ("+", "-", "*") now accept multiple tags with
51 "+" or "-" prefix, like "*" operation in notmuch-search view before.
53 "*" operation (`notmuch-show-tag-all') is now available in
56 `Notmuch-show-{add,remove}-tag' functions no longer accept tag
57 argument, `notmuch-show-tag-message' should be used instead. Custom
58 bindings using these functions should be updated, e.g.:
60 (notmuch-show-remove-tag "unread")
64 (notmuch-show-tag-message "-unread")
71 notmuch_query_add_tag_exclude supports the new tag exclusion
77 Compatibility with GMime 2.6
79 It is now possible to build notmuch against both GMime 2.4 and 2.6.
80 However, a bug in current GMime 2.6 causes notmuch not to report
81 signatures where the signer key is unavailable (GNOME bug 668085).
83 Notmuch 0.11.1 (2012-02-03)
84 ===========================
89 Fix error handling in python bindings.
91 The python bindings in 0.11 failed to detect NULL pointers being
92 returned from libnotmuch functions and thus failed to raise
93 exceptions to indicate the error condition. Any subsequent calls
94 into libnotmuch caused segmentation faults.
96 Quote MML tags in replies
98 MML tags are text codes that Emacs uses to indicate attachments
99 (among other things) in messages being composed. The Emacs
100 interface did not quote MML tags in the quoted text of a reply.
101 User could be tricked into replying to a maliciously formatted
102 message and not editing out the MML tags from the quoted text. This
103 could lead to files from the user's machine being attached to the
104 outgoing message. The Emacs interface now quotes these tags in
105 reply text, so that they do not effect outgoing messages.
107 Notmuch 0.11 (2012-01-13)
108 =========================
110 Command-Line Interface
111 ----------------------
115 Hooks have been introduced to notmuch. Hooks are scripts that notmuch
116 invokes before and after certain actions. Initially, "notmuch new"
117 supports "pre-new" and "post-new" hooks that are run before and after
118 importing new messages into the database.
120 notmuch reply --decrypt bugfix
122 The "notmuch reply" command with --decrypt argument had a rarely
123 occurring bug that caused an encrypted message not to be decrypted
124 sometimes. This is now fixed.
129 Automatic tag query optimization
131 "notmuch tag" now automatically optimizes the user's query to
132 exclude messages whose tags won't change. In the past, we've
133 suggested that people do this by hand; this is no longer necessary.
135 Don't sort messages when creating a dump file
137 This speeds up tag dumps considerably, without any loss of
138 information. To replicate the old behavior of sorted output (for
139 example to compare two dump files), one can use e.g. sort(1).
144 Reduction of memory leaks
146 Two memory leaks when searching and showing messages were identified
147 and fixed in this release.
154 notmuch-show-advance (bound to the spacebar in notmuch-show-mode) had
155 a bug that caused it to always jump to the next message, even if it
156 should have scrolled down to show more of the current message instead.
159 Support "notmuch new" as a notmuch-poll-script
161 It's now possible to use "notmuch new" as a notmuch-poll-script
162 directly. This is also the new default. This allows taking better
163 advantage of the "notmuch new" hooks from emacs without intermediate
166 Improvements in saved search management
168 New saved searches are now appended to the list of saved searches,
169 not inserted in front. It's also possible to define a sort function
170 for displaying saved searches; alphabetical sort is provided.
172 Hooks for notmuch-hello
174 Two new hooks have been added: "notmuch-hello-mode-hook" (called after
175 entering notmuch-hello-mode) and "notmuch-hello-refresh-hook" (called
176 after updating a notmuch-hello buffer).
178 New face for crypto parts headers
180 Crypto parts used to be displayed with a hardcoded color. A new face
181 has been introduced to fix this: notmuch-crypto-part-header. It
182 defaults to the same value as before, but can be customized to match
185 Use space as default thousands separator
187 Large numbers in notmuch-hello are now displayed using a space as
188 thousands separator (e.g. "123 456" instead of "123,456"). This can be
189 changed by customizing "notmuch-hello-thousands-separator".
191 Call notmuch-show instead of notmuch-search when clicking on
192 buttonized id: links.
194 New function notmuch-show-advance
196 This new function advances through just the current thread, and is
197 less invasive than notmuch-show-advance-and-archive. It can easily
198 be bound to SPC with:
200 (define-key notmuch-show-mode-map " " 'notmuch-show-advance)
202 Various performance improvements.
207 The tool contrib/notmuch-deliver helps with initial delivery and
208 tagging of mail (replacing running notmuch new).
211 Notmuch 0.10.2 (2011-12-04)
212 ===========================
217 Fix crash in python bindings.
219 The python bindings did not call g_type_init, which caused crashes
220 for some, but not all users.
222 Notmuch 0.10.1 (2011-11-25)
223 ===========================
230 Argument processing changes in 0.10 introduced a bug where "notmuch
231 --help" crashed while "notmuch help" worked fine. This is fixed in
234 Notmuch 0.10 (2011-11-23)
235 =========================
237 New build and testing features
238 ------------------------------
240 Emacs tests are now done in dtach. This means that dtach is now
241 needed to run the notmuch test suite, at least until the checking for
242 prerequisites is improved.
244 Full test coverage of the stashing feature in Emacs.
246 New command-line features
247 -------------------------
249 Add "notmuch restore --accumulate" option
251 The --accumulate switch causes the union of the existing and new tags to be
252 applied, instead of replacing each message's tags as they are read in from
255 Add search terms to "notmuch dump"
257 The dump command now takes an optional search term much like notmuch
258 search/show/tag. The output file argument of dump is deprecated in
259 favour of using stdout.
261 Add "notmuch search" --offset and --limit options
263 The search command now takes options --offset=[-]N and --limit=N to limit
264 the number of results shown.
266 Add "notmuch count --output" option
268 The count command is now capable of counting threads in addition to
269 messages. This is selected using the new --output=(threads|messages) option.
271 New emacs UI features
272 ---------------------
274 Add tab-completion for notmuch-search and notmuch-search-filter
276 These functions now support completion tags for query parts
277 starting with "tag:".
279 Turn "id:MSG-ID" links into buttons associated with notmuch searches
281 Text of the form "id:MSG-ID" in mails is now a clickable button that
282 opens a notmuch search for the given message id.
284 Add keybinding ('c I') for stashing Message-ID's without an id: prefix
286 Reduces manual labour when stashing them for use outside notmuch.
288 Do not query on notmuch-search exit
290 It is harmless to kill the external notmuch process, so the user
291 is no longer interrogated when they interrupt a search.
296 Emacs now constructs large search buffers more efficiently
298 Search avoids opening and parsing message files
300 We now store more information in the database so search no longer
301 has to open every message file to get basic headers. This can
302 improve search speed by as much as 10X, but taking advantage of this
303 requires a database rebuild:
305 notmuch dump > notmuch.dump
306 # Backup, then remove notmuch database ($MAIL/.notmuch)
308 notmuch restore notmuch.dump
310 New collection of add-on tools
311 ------------------------------
313 The source directory "contrib" contains tools built on notmuch. These
314 tools are not part of notmuch, and you should check their individual
315 licenses. Feel free to report problems with them to the notmuch
318 nmbug - share tags with a given prefix
320 nmbug helps maintain a git repo containing all tags with a given
321 prefix (by default "notmuch::"). Tags can be shared by commiting
322 them to git in one location and restoring in another.
324 Notmuch 0.9 (2011-10-01)
325 ========================
327 New, general features
328 ---------------------
330 Correct handling of interruptions during "notmuch new"
332 "notmuch new" now operates as a series of small, self-consistent
333 transactions, so it can correctly resume after an interruption or
334 crash. Previously, interruption could lose existing tags, fail to
335 detect messages on resume, or leave the database in a state
336 temporarily or permanently inconsistent with the mail store.
343 notmuch_database_begin_atomic and notmuch_database_end_atomic allow
344 multiple database operations to be performed atomically.
346 notmuch_database_find_message_by_filename does exactly what it says.
350 notmuch_database_find_message (and n_d_f_m_by_filename) now return
351 a status indicator and uses an output parameter for the
352 message. This change required changing the SONAME of libnotmuch to
355 Python bindings changes
356 -----------------------
358 - Re-encode python unicode objects to utf-8 before passing back to
360 - Support Database().begin_atomic()/end_atomic()
361 - Support Database().find_message_by_filename()
362 NB! This needs a db opened in READ-WRITE mode currently, or it will crash
363 the python process. The is a limitation (=bug) of the underlying libnotmuch.
364 - Fixes where we would not throw NotmuchErrors when we should (Justus Winter)
365 - Update for n_d_find_message* API changes (see above).
367 Ruby bindings changes
368 ---------------------
370 - Wrap new library functions notmuch_database_{begin,end}_atomic.
371 - Add new exception Notmuch::UnbalancedAtomicError.
372 - Rename destroy to destroy! according to Ruby naming conventions.
373 - Update for n_d_find_message* API changes (see above).
378 * Add gpg callback to crypto sigstatus buttons to retrieve/refresh
380 * Add notmuch-show-refresh-view function (and corresponding binding)
381 to refresh the view of a notmuch-show buffer.
383 Reply formatting cleanup
384 ------------------------
386 "notmuch reply" no longer includes notification that non-leafnode
387 MIME parts are being suppressed.
389 Notmuch 0.8 (2011-09-10)
390 ========================
392 Improved handling of message/rfc822 parts
394 Both in the CLI and the emacs interface. Output of rfc822 parts now
395 includes the primary headers, as well as the body and all subparts.
396 Output of the completely raw rfc822-formatted message, including all
397 headers, is unfortunately not yet supported (but hopefully will be
400 Improved Build system portability
402 Certain parts of the shell script generating notmuch.sym were
403 specific to the GNU versions of sed and nm. The new version should
404 be more portable to e.g. OpenBSD.
406 Documentation update for Ruby bindings
408 Added documentation, typo fixes, and improved support for rdoc.
410 Unicode, iterator, PEP8 changes for python bindings
412 - PEP8 (code formatting) changes for python files.
413 - Remove Tags.__len__ ; see 0.6 release notes for motivation.
414 - Decode headers as UTF8, encode (unicode) database paths as UTF8.
416 Notmuch 0.7 (2011-08-01)
417 ========================
419 Vim interface improvements
420 --------------------------
422 Jason Woofenden provided a number of bug fixes for the Vim interface
424 * fix citation/signature fold lengths
425 * fix cig/cit parsing within multipart/*
426 * fix on-screen instructions for show-signature
427 * fix from list reformatting in search view
428 * fix space key: now archives (did opposite)
430 Uwe Kleine-König contributed
432 * use full path for sendmail/doc fix
433 * fix compose temp file name
435 Python Bindings changes
436 -----------------------
438 Sebastian Spaeth contributed two changes related to unicode and UTF8:
440 * message tags are now explicitly unicode
441 * query string is encoded as a UTF8 byte string
443 Build-System improvements
444 ------------------------
446 Generate notmuch.sym after the relevant object files
448 This fixes a bug in parallel building. Thanks to Thomas Jost for the
451 Notmuch 0.6.1 (2011-07-17)
452 ==========================
457 Re-export Xapian exception typeinfo symbols.
459 It turned out our aggressive symbol hiding caused problems for
460 people running gcc 4.4.5.
462 Notmuch 0.6 (2011-07-01)
463 =======================
464 New, general features
465 ---------------------
466 Folder-based searching
468 Notmuch queries can now include a search term to match the
469 directories in which mail files are stored (within the mail
470 storage). The syntax is as follows:
474 For example, one might use things such as:
480 to match any path containing a directory "spam", "work/todo", or
481 containing a directory starting with "2011-", respectively.
483 This feature is particularly useful for users of delivery-agent
484 software (such as procmail or maildrop) that is filtering mail and
485 delivering it to particular folders, or users of systems such as
486 Gmail that use filesystem directories to indicate message tags.
488 NOTE: Only messages that are newly indexed with this version of
489 notmuch will be searchable with folder: terms. In order to enable
490 this feature for all mail, the entire notmuch index will need to be
493 notmuch dump > notmuch.dump
494 # Backup, then remove notmuch database ($MAIL/.notmuch)
496 notmuch restore notmuch.dump
500 Both the command line interface and the emacs-interface have new
501 support for PGP/MIME, detailed below. Thanks to Daniel Kahn Gillmor
502 and Jameson Graef Rollins for making this happen.
504 New, automatic tags: "signed" and "encrypted"
506 These tags will automatically be applied to messages containing
507 multipart/signed and multipart/encrypted parts.
509 NOTE: Only messages that are newly indexed with this version of
510 notmuch will receive these tags.
512 New command-line features
513 -------------------------
514 Add new "notmuch show --verify" option for signature verification
516 This option instruct notmuch to verify the signature of
517 PGP/MIME-signed parts.
519 Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
521 This option instructs notmuch to decrypt PGP/MIME-encrypted parts.
522 Note that this feature currently requires gpg-agent and a passphrase entry
523 tool (e.g. pinentry-gtk or pinentry-curses).
525 Proper nesting of multipart parts in "notmuch show" output
527 MIME parts are now display with proper nesting to reflect original
528 MIME hierarchy of a message. This allows clients to correctly
529 analyze the MIME structure, (such as, for example, determining to
530 which parts a signature part applies).
532 Add new "notmuch show --part" option
534 This is a replacement for the older "notmuch part" command, (which
535 is now deprecated—it should still work as always, but is no longer
536 documented). Putting part output under "notmuch show" allows for all
537 of the "notmuch show" options to be applied when extracting a single
538 part, (such as --format=json for extracting a message part with JSON
541 Deprecate "notmuch search-tags", (in favor of "notmuch search --output=tags *")
543 The "notmuch search-tags" sub-command has been redundant since the
544 addition of the --output=tags option to "notmuch search". We now
545 make that more clear by deprecating "notmuch search-tags", (dropping
546 it from the documentation). We do continue to support the old syntax
547 by translating it internally to the new call.
549 Performance improvements
550 ------------------------
551 Faster searches (by doing fewer searches to construct threads)
553 Whenever a user asks for search results as threads, notmuch first
554 performs a search for messages matching the query, then performs
555 additional searches to find other messages in the resulting threads.
557 Removing inefficiencies and redundancies in these secondary searches
558 results in a measured speedups of 1.5x for a typical search.
560 Faster searches (by doing fewer passes to gather message data)
562 Optimizing Xapian data access patterns (using a single pass to get
563 all message-document data rather than a pass for each data type)
564 results in a measured speedup of 1.7x for a typical search.
566 The benefits of this optimization combine with the preceding
567 optimization. With both in place, Austin Clements measured a speedup
568 of 2.5x for a search of all messages in his inbox (was 4.5s, now
569 1.8s). Thanks, Austin!
571 Faster initial indexing
573 More efficient indexing of new messages results in a measured
574 speedup of 1.4x for the initial indexing of 3 GB of mail (1h 14m
575 rather than 1h 46m). Thanks to Austin Clements and Michal Sojka.
577 Make "notmuch new" faster for unchanged directories
579 Optimizing to not do any further examinations of sub-directories
580 when the filesystem indicates that a directory is unchanged from the
581 last "notmuch new" results in measured speedups of 8.5 for the "No
582 new mail" case, (was 0.77s, now 0.09s). Thanks to Karel Zak.
584 New emacs-interface features
585 ----------------------------
587 Support for PGP/MIME (GnuPG)
589 Automatically indicate validity of signatures for multipart/signed
590 messages. Automatically display decrypted content for
591 multipart/encrypted messages. See the emacs variable
592 notmuch-crypto-process-mime for more information. Note that this
593 needs gpg-agent and a pinentry tool just as the command line tools.
594 Also note there is no support SMIME yet.
596 Output of pipe command is now displayed if pipe command fails
598 This is extremely useful in the common use case of piping a patch to
599 "git am". If git fails to cleanly merge the patch the error messages
600 from the failed merge are now clearly displayed to the user, (where
601 previously they were silently hidden from the user).
603 User-selectable From address
605 A user can choose which configured email addresses should be used as
606 the From address whenever composing a new message. To do so, simply
607 press C-u before the command which will open a new message. Emacs
608 will prompt for the from address to use.
610 The user can customize the "Notmuch Identities" setting in the
611 notmuch customize group in order to use addresses other than those in
612 the notmuch configuration file if desired.
614 The user can also choose to always be prompted for the from address
615 when composing a new message (without having to use C-u) by setting
616 the "Notmuch Always Prompt For Sender" option in the notmuch
619 Hiding of repeated subjects in collapsed thread view
621 In notmuch-show mode, if a collapsed message has the same subject as
622 its parent, the subject is not shown.
624 Automatic detection and hiding of original message in top-posted message
626 When a message contains a line looking something like:
628 ----- Original Message -----
630 emacs hides this and all subsequent lines as an "original message",
631 (allowing the user to click or press enter on the "original message"
632 button to display it again). This makes the handling of top-posted
633 citations work much like conventional citations.
635 New hooks for running code when tags are modified
637 Some users want to perform additional actions whenever a particular
638 tag is added/removed from a message. This could be used to, for
639 example, interface with some external spam-recognition training
640 tool. To facilitate this, two new hooks are added which can be
641 modified in the following settings of the notmuch customize group:
643 Notmuch Before Tag Hook
644 Notmuch After Tag Hook
646 New optional support for hiding some multipart/alternative parts
648 Many emails are sent with redundant content within a
649 multipart/alternative group (such as a text/plain part as well as a
650 text/html part). Users can configure the setting:
652 Notmuch Show All Multipart/Alternative Parts
654 to "off" in the notmuch customize group to have the interface
655 automatically hide some part alternatives (such as text/html
656 parts). This new part hiding is not configured by default yet
657 because there's not yet a simple way to re-display such a hidden
658 part if it is not actually redundant with a displayed part.
660 Better rendering of text/x-vcalendar parts
662 These parts are now displayed in a format suitable for use with the
665 Avoid getting confused by Subject and Author fields with newline characters
667 Replacing all characters with ASCII code less than 32 with a question mark.
669 Cleaner display of From line in email messages (remove double quotes,
670 and drop "name" if it's actually just a repeat of the email address).
672 Vim interface improvements
673 --------------------------
674 Felipe Contreras provided a number of updates for the vim interface:
676 * Using sendmail directly rather than mailx,
677 * Implementing archive in show view
678 * Add support to mark as read in show and search views
679 * Add delete commands
682 Bindings improvements
683 ---------------------
684 Ruby bindings are now much more complete
686 Including QUERY.sort, QUERY.to_s, MESSAGE.maildir_flags_to_tags,
687 MESSAGE.tags_to_maildir_flags, and MESSAGE.get_filenames
689 * Python bindings have been updated and extended
690 (docs online at http://packages.python.org/notmuch/)
693 - Message().get_filenames(),
694 - Message().tags_to_maildir_flags(),Message().maildir_flags_to_tags()
695 - list(Threads()) and list(Messages) works now
697 - Message().__cmp__() and __hash__()
698 These allow, for example:
701 As well as set arithmetic on Messages():
703 s1, s2= set(msgs1), set(msgs2)
708 - len(Messages()) as it exhausted the iterator.
709 Use len(list(Messages())) or
710 Query.count_messages() to get the length.
712 Added initial Go bindings in bindings/go
714 New build-system features
715 -------------------------
716 Added support for building in a directory other than the source directory
718 This can be used with the widely-supported idiom of simply running
719 the configure script from some other directory:
726 Fix to save configure options for future, implicit runs of configure
728 When a user updates the source (such as with "git pull") calling
729 "make" may cause an automatic re-run of the configure script. When
730 this happens, the configure script will automatically be called with
731 the same options the user originally passed in the most-recent
732 manual invocation of configure.
734 New test-suite feature
735 ----------------------
736 Binary for bash for running test suite now located via PATH.
738 The notmuch test suite requires a fairly recent version of bash (>=
739 bash 4). As some systems supply an older version of bash at
740 /bin/bash, the test suite is now updated to search $PATH to locate
741 the bash binary. This allows users of systems with old /bin/bash to
742 simply install bash >= 4 somewhere on $PATH before /bin and then use
745 Support for testing output with a trailing newline.
747 Previously, some tests would fail to notice a difference in the
748 presence/absence of a trailing newline in a program output, (which
749 has led to bugs in the past). Now, carefully-written tests (using
750 test_expect_equal_file rather than test_expect_equal) will detect
751 any change in the presence/absence of a trailing newline. Many tests
752 are updated to take advantage of this.
754 Avoiding accessing user's $HOME while running test suite
756 The test suite now carefully creates its own HOME directory. This
757 allows the test suite to be run with no existing HOME directory, (as
758 some build systems apparently do), and avoids test-suite differences
759 due to configuration files in the users HOME directory.
764 Output *all* files for "notmuch search --output=files"
766 For the cases where multiple files have the same Message ID,
767 previous versions of notmuch would output only one such file. This
768 command is now fixed to correctly output all files.
770 Fixed spurious search results from "overlapped" indexing of addresses
772 This fixed a bug where a search for:
774 to:user@elsewhere.com
776 would incorrectly match a message sent:
778 To: user@example,com, someone@elsewhere.com
780 Fix --output=json when search has no results
782 A bug present since notmuch 0.4 had caused searches with no results
783 to produce an invalid json object. This is now fixed to cleanly
784 return a valid json object representing an empty array "[]" as
787 fix the automatic detection of the From address for "notmuch reply"
788 from the Received headers in some cases.
790 Fix core dump on DragonFlyBSD due to -1 return value from
791 sysconf(_SC_GETPW_R_SIZE_MAX).
793 Cleaned up several memory leaks
795 Eliminated a few, rare segmentation faults and a double-free.
797 Fix libnotmuch library to only export notmuch API functions
799 Previous release of the notmuch library also exported some Xapian
800 C++ exception type symbols. These were never part of the library
801 interface and were never intended to be exported.
803 Emacs-interface bug fixes
804 -------------------------
805 Display any unexpected output or errors from "notmuch search" invocations
807 Previously any misformatted output or trailing error messages were
808 silently ignored. This output is now clearly displayed. This fix was
809 very helpful in identifying and fixing the bug described below.
811 Fix bug where some threads would be missing from large search results
813 When a search returned a "large" number of results, the emacs
814 interface was incorrectly dropping one thread every time the output
815 of the "notmuch search" process spanned the emacs read-buffer. This
818 Avoid re-compression of .gz files (and similar) when saving attachment
820 Emacs was being too clever for its own good and trying to
821 re-compress pre-compressed .gz files when saving such attachments
822 (potentially corrupting the attachment). The emacs interface is
823 fixed to avoid this bug.
825 Fix hiding of a message when a previously-hidden citation is visible
827 Previously the citation would remain visible in this case. This is
828 fixed so that hiding a message hides all parts.
830 Notmuch 0.5 (2010-11-11)
831 ========================
832 New, general features
833 ---------------------
834 Maildir-flag synchronization
836 Notmuch now knows how to synchronize flags in maildir filenames with
837 tags in the notmuch database. The following flag/tag mappings are
846 'S' unread (added when 'S' flag is not present)
848 The synchronization occurs in both directions, (for example, adding
849 the 'S' flag to a file will cause the "unread" tag to be added, and
850 adding the "replied" tag to a message will cause the file to be
851 renamed with an 'R' flag).
853 This synchronization is enabled by default for users of the
854 command-line interface, (though only files in directories named
855 "cur" or "new" will be renamed). It can be disabled by setting the
856 new maildir.synchronize_flags option in the configuration file. For
859 notmuch config set maildir.synchronize_flags false
861 Users upgrading may also want to run "notmuch setup" once (just
862 accept the existing configuration) to get a new, nicely-commented
863 [maildir] section added to the configuration file.
865 For users of the notmuch library, the new synchronization
866 functionality is available with the following two new functions:
868 notmuch_message_maildir_flags_to_tags
869 notmuch_message_tags_to_maildir_flags
871 It is anticipated that future improvements to this support will
872 allow for safe synchronization of the 'T' flag with the "deleted"
873 tag, as well as support for custom flag/tag mappings.
877 Support for querying multiple filenames for a single message
879 It is common for the mailstore to contain multiple files with the
880 same message ID. Previously, notmuch would always hide these
881 duplicate files, (returning a single, arbitrary filename with
882 notmuch_message_get_filename).
884 With this release, library users can access all filenames for a
885 message with the new function:
887 notmuch_message_get_filenames
889 Together with notmuch_filenames_valid, notmuch_filenames_get, and
890 notmuch_filenames_move_to_next it is now possible to iterate over
891 all available filenames for a given message.
893 New command-line features
894 -------------------------
895 New "notmuch show --format=raw" for getting at original email contents
897 This new feature allows for a fully-functional email client to be
898 built on top of the notmuch command-line without needing any direct
899 access to the mail store itself.
901 For example, it's now possible to run "emacs -f notmuch" on a local
902 machine with only ssh access to the mail store/notmuch database. To
903 do this, simply set the notmuch-command variable in emacs to the
904 name of a script containing:
906 ssh user@host notmuch "$@"
908 If the ssh client has enabled connection sharing (ControlMaster
909 option in OpenSSH), the emacs interface can be quite responsive this
914 Fix "notmuch search" to print nothing when nothing matches
916 The 0.4 release had a bug in which:
918 notmuch search <expression-with-no-matches>
920 would produce a single blank line of output, (where previous
921 versions would produce no output. This fix also causes a change in
922 the --format=json output, (which would previously produce "[]" and
923 now produces nothing).
925 Emacs interface improvements
926 ----------------------------
927 Fix to allow pipe ('|') command to work when using notmuch over ssh
929 Fix count of lines in hidden signatures.
931 Omit repeated subject lines in (collapsed) thread display.
933 Display current thread subject in a header line.
935 Provide a "c i" binding to copy a thread ID from the search view.
937 Allow for notmuch-fcc-dirs to have a value of nil.
939 Also, the more complex form of notmuch-fcc-dirs now has a slightly
940 different format. It no longer has a special first-element, fallback
941 string. Instead it's now a list of cons cells where the car of each
942 cell is a regular expression to be matched against the sender
943 address, and the cdr is the name of a folder to use for an FCC. So
944 the old fallback behavior can be achieved by including a final cell
945 of (".*" . "default-fcc-folder").
947 Vim interface improvements
948 --------------------------
949 Felipe Contreras provided a number of updates for the vim interface.
951 These include optimizations, support for newer versions of vim, fixed
952 support for sending mail on modern systems, new commands, and
957 Added initial ruby bindings in bindings/ruby
959 Notmuch 0.4 (2010-11-01)
960 ========================
961 New command-line features
962 -------------------------
963 notmuch search --output=(summary|threads|messages|tags|files)
965 This new option allows for particular items to be returned from
966 notmuch searches. The "summary" option is the default and behaves
967 just as "notmuch search" has historically behaved.
969 The new option values allow for thread IDs, message IDs, lists of
970 tags, and lists of filenames to be returned from searches. It is
971 expected that this new option will be very useful in shell
972 scripts. For example:
974 for file in $(notmuch search --output=files <search-terms>); do
975 <operations-on> "$file"
978 notmuch show --format=mbox <search-specification>
980 This new option allows for the messages matching a search
981 specification to be presented as an mbox. Specifically the "mboxrd"
982 format is used which allows for reversible quoting of lines
983 beginning with "From ". A reader should remove a single '>' from the
984 beginning of all lines beginning with one or more '>' characters
985 followed by the 5 characters "From ".
987 notmuch config [get|set] <section>.<item> [value ...]
989 The new top-level "config" command allows for any value in the
990 notmuch configuration file to be queried or set to a new value. Both
991 single-valued and multi-valued items are supported, as our any
992 custom items stored in the configuration file.
994 Avoid setting Bcc header in "notmuch reply"
996 We decided that this was a bit heavy-handed as the actual mail
997 user-agent should be responsible for setting any Bcc option. Also,
998 see below for the notmuch/emacs user-agent now setting an Fcc by
999 default rather than Bcc.
1001 New library features
1002 --------------------
1003 Add notmuch_query_get_query_string and notmuch_query_get_sort
1005 These are simply functions for querying properties of a
1006 notmuch_query_t object.
1010 Enable Fcc of all sent messages by default (to "sent" directory)
1012 All messages sent from the emacs interface will now be saved to the
1013 notmuch mail store where they will be incorporated to the database
1014 by the next "notmuch new". By default, messages are saved to the
1015 "sent" directory at the top-level of the mail store. This directory
1016 can be customized by means of the "Notmuch Fcc Dirs" option in the
1017 notmuch customize interface.
1019 Ability to all open messages in a thread to a pipe
1021 Historically, the '|' keybinding allows for piping a single message
1022 to an external command. Now, by prefixing this key with a prefix
1023 argument, (for example, by pressing "Control-U |"), all open
1024 messages in the current thread will be sent to the external command.
1026 Optional support for detecting inline patches
1028 This hook is disabled by default but can be enabled with a checkbox
1029 under "Notmuch Show Insert Text/Plain Hook" in the notmuch customize
1030 interface. It allows for inline patches to be detected and treated
1031 as if they were attachments, (with context-sensitive highlighting).
1033 Automatically tag messages as "replied" when sending a reply
1035 Messages replied to within the emacs interface will now be tagged as
1036 "replied". This feature can easily be customized to add or remove
1037 other tags as well. For example, a user might use a tag of
1038 "needs-reply" and can configure this feature to automatically remove
1039 that tag when replying. See "Notmuch Message Mark Replied" in the
1040 notmuch customize interface.
1042 Allow search-result color specifications to overlay each other
1044 For example, one tag can specify the background color of matching
1045 lines, while another can specify the foreground. With this change,
1046 both settings will now be visible simultaneously, (which was not the
1047 case in previous releases). See "Notmuch Search Line Faces" in the
1048 notmuch customize interface.
1050 Make hidden author names still available for incremental search.
1052 When there is insufficient space to display all authors of a thread
1053 in search results, the names of hidden authors are now still made
1054 available to emacs' incremental search commands. As the user
1055 searches, matching lines will temporarily expand to show the hidden
1058 New binding of Control-TAB (works like TAB in reverse)
1060 Many notmuch nodes already use TAB to navigate forward through
1061 various items allowing actions, (message headers, email attachments,
1062 etc.). The new Control-TAB binding operates similarly but in the
1065 New build-system features
1066 -------------------------
1067 Various portability fixes have been applied
1069 These include fixes for build failures on at least Solaris, FreeBSD,
1070 and Fedora systems. We're hopeful that the notmuch code base is now
1071 more portable than ever before.
1073 Arrange for libnotmuch to be found automatically after make install
1075 The notmuch build system is now careful to help the user avoid
1076 errors of the form "libnotmuch.so could not be found" immediately
1077 after installing. This support takes two forms:
1079 1. If the library is installed to a system directory,
1080 (configured in /etc/ld.so.conf), then "make install" will
1081 automatically run ldconfig.
1083 2. If the library is installed to a non-system directory, the
1084 build system adds a DR_RUNPATH entry to the final binary
1085 pointing to the directory to which the library is installed.
1087 When this support works, the user should be able to run notmuch
1088 immediately after "make install", without any errors trying to find
1089 the notmuch library, and without having to manually set environment
1090 variables such as LD_LIBRARY_PATH.
1092 Check compiler/linker options before using them
1094 The configure script now carefully checks that any desired
1095 compilation options, (whether for enabling compiler warnings, or for
1096 embedding rpath, etc.), are supported. Only supported options are
1097 used in the resulting Makefile.
1099 New test-suite features
1100 -----------------------
1101 New modularization of test suite.
1103 Thanks to a gracious relicensing of the test-suite infrastructure
1104 from the git project, notmuch now has a modular test suite. This
1105 provides the ability to run individual sections of the test suite
1106 rather than the whole things. It also provides better summary of
1107 test results, with support for tests that are expected to fail
1108 (BROKEN and FIXED) in addition to PASS and FAIL. Finally, it makes
1109 it easy to run the test suite within valgrind (pass --valgrind to
1110 notmuch-test or to any sub-script) which has been very useful.
1112 New testing of emacs interface.
1114 The test suite has been augmented to allow automated testing of the
1115 emacs interfaces. So far, this includes basic searches, display of
1116 threads, and tag manipulation. This also includes a test that a new
1117 message can successfully be sent out through a (dummy) SMTP server
1118 and that said message is successfully integrated into the notmuch
1119 database via the FCC setting.
1123 Fix potential corruption of database when "notmuch new " is interrupted.
1125 Previously, an interruption of "notmuch new" would (rarely) result
1126 in a corrupt database. The corruption would manifest itself by a
1127 persistent error of the form:
1129 document ID of 1234 has no thread ID
1131 The message-adding code has been carefully audited and reworked to
1132 avoid this sort of corruption regardless of when it is interrupted.
1134 Fix failure with extremely long message ID headers.
1136 Previously, a message with an extremely long message ID, (say, more
1137 than 300 characters), would fail to be added to notmuch, (triggering
1138 Xapian exceptions). This has now been fixed.
1140 Fix for messages with "charset=unknown-8bit"
1142 Previously, messages with this charset would cause notmuch to emit a
1143 GMime warning, (which would then trip up emacs or other interfaces
1144 parsing the notmuch results).
1146 Fix notmuch_query_search_threads function to return NULL on any exception
1148 Fix "notmuch search" to return non-zero if notmuch_query_search_threads fails
1150 Previously, this command could confusingly report a Xapian
1151 exception, yet still return an error code of 0. It now correctly
1152 returns a failing error code of 1 in this case.
1156 Fix to handle a message with a subject containing, for example "[1234]"
1158 Previously, a message subject containing a sequence of digits within
1159 square brackets would cause the emacs interface to mis-parse the
1160 output of "notmuch search". This would result in the message being
1161 mis-displayed and prevent the user from manipulating the message in
1162 the emacs interface.
1164 Fix to correctly handle message IDs containing ".."
1166 The emacs interface now properly quotes message IDs to avoid a
1167 Xapian bug in which the ".." within a message ID would be
1168 misinterpreted as a numeric range specification.
1170 Python-binding fixes
1171 --------------------
1172 The python bindings for notmuch have been updated to work with python3.
1174 Debian-specific fixes
1175 ---------------------
1176 Fix emacs initialization so "M-x notmuch" works for users by default.
1178 Now, a new Debian user can immediately run "emacs -f notmuch" after
1179 "apt-get install notmuch". Previously, the user would have had to
1180 edit the ~/.emacs file to add "(require 'notmuch)" before this would
1183 Notmuch 0.3.1 (2010-04-27)
1184 ==========================
1187 Fix an infinite loop in "notmuch reply"
1189 This bug could be triggered by replying to a message where the
1190 user's primary email address did not appear in the To: header and
1191 the user had not configured any secondary email addresses. The bug
1192 was a simple re-use of the same iterator variable in nested loops.
1194 Fix a potential SEGV in "notmuch search"
1196 This bug could be triggered by an author name ending in a ','.
1197 Admittedly - that's almost certainly a spam email, but we never
1198 want notmuch to crash.
1202 Fix calculations for line wrapping in the primary "notmuch" view.
1204 Fix Fcc support to prompt to create a directory if the specified Fcc
1205 directory does not exist.
1209 Fix build on OpenSolaris (at least) due to missing 'extern "C"' block.
1211 Without this, the C++ sources could not find strcasestr and the
1212 final linking of notmuch would fail.
1214 Notmuch 0.3 (2010-04-27)
1215 ========================
1216 New command-line features
1217 -------------------------
1218 User-configurable tags for new messages
1220 A new "new.tags" option is available in the configuration file to
1221 determine which tags are applied to new messages. Run "notmuch
1222 setup" to generate new documentation within ~/.notmuch-config on how
1223 to specify this value.
1225 Threads search results named based on subjects that match search
1227 This means that when new mails arrived to a thread you've previously
1228 read, and the new mails have a new subject, you will see that
1229 subject in the search results rather than the old subject.
1231 Faster operation of "notmuch tag" (avoid unneeded sorting)
1233 Since the user just wants to tag all matching messages, we can make
1234 things perform a bit faster by avoiding the sort.
1236 Even Better guessing of From: header for "notmuch reply"
1238 Notmuch now looks at a number of headers when trying to figure out
1239 the best From: header to use in a reply. This is helpful if you have
1240 several configured email addresses, and you also subscribe to various
1241 mailing lists with different addresses, (so that mails you are
1242 replying to won't always include your subscribed address in the To:
1245 Indication of author names that match a search
1247 When notmuch displays threads as the result of a search, it now
1248 lists the authors that match the search before listing the other
1249 authors in the thread. It inserts a pipe '|' symbol between the last
1250 matching and first non-matching author. This is especially useful in
1251 a search that includes tag:unread. Now the authors of the unread
1252 messages in the thread are listed first.
1254 New: Python bindings
1255 --------------------
1256 Sebastian Spaeth has contributed his python bindings for the notmuch
1257 library to the central repository. These bindings were previously
1258 known as "cnotmuch" within python but have now been renamed to be
1259 accessible with a simple, and more official-looking "import notmuch".
1261 The bindings have already proven very useful as people proficient in
1262 python have been able to easily develop programs to do notmuch-based
1263 searches for email-address completion, maildir-flag synchronization,
1266 These bindings are available within the bindings/python directory, but
1267 are not yet integrated into the top-level Makefiles, nor the top-level
1268 package-building scripts. Improvements are welcome.
1270 Emacs interface improvements
1271 ----------------------------
1272 An entirely new initial view for notmuch, (friendly yet powerful)
1274 Some of us call the new view "notmuch hello" but you can get at it
1275 by simply calling "emacs -f notmuch". The new view provides a search
1276 bar where new searches can be performed. It also displays a list of
1277 recent searches, along with a button to save any of these, giving it
1278 a new name as a "saved search". Many people find these "saved
1279 searches" one of the most convenient ways of organizing their mail,
1280 (providing all of the features of "folders" in other mail clients,
1281 but without any of the disadvantages).
1283 Finally, this view can also optionally display all of the tags that
1284 exist in the database, along with a count for each tag, and a custom
1285 search of messages with that tag that's simply a click (or keypress)
1288 Note: For users that liked the original mode of "emacs -f notmuch"
1289 immediately displaying a particular search result, we
1290 recommend instead running something like:
1292 emacs --eval '(notmuch search "tag:inbox" t)'
1294 The "t" means to sort the messages in an "oldest first" order,
1295 (as notmuch would do previously by default). You can also
1296 leave that off to have your search results in "newest first"
1299 Full-featured "customize" support for configuring notmuch
1301 Notmuch now plugs in well to the emacs "customize" mode to make it
1302 much simpler to find things about the notmuch interface that can be
1303 tweaked by the user.
1305 You can get to this mode by starting at the main "Customize" menu in
1306 emacs, then browsing through "Applications", "Mail", and
1307 "Notmuch". Or you can go straight to "M-x customize-group"
1310 Once you're at the customize screen, you'll see a list of documented
1311 options that can be manipulated along with checkboxes, drop-down
1312 selectors, and text-entry boxes for configuring the various
1315 Support for doing tab-completion of email addresses
1317 This support currently relies on an external program,
1318 (notmuch-addresses), that is not yet shipped with notmuch
1319 itself. But multiple, suitable implementations of this program have
1320 already been written that generate address completions by doing
1321 notmuch searches of your email collection. For example, providing
1322 first those addresses that you have composed messages to in the
1325 One such program (implemented in python with the python bindings to
1326 notmuch) is available via:
1328 git clone http://jkr.acm.jhu.edu/git/notmuch_addresses.git
1330 Install that program as notmuch-addresses on your PATH, and then
1331 hitting TAB on a partial email address or name within the To: or Cc:
1332 line of an email message will provide matching completions.
1334 Support for file-based (Fcc) delivery of sent messages to mail store
1336 This isn't yet enabled by default. To enable this, one will have to
1337 set the "Notmuch Fcc Dirs" setting within the notmuch customize
1338 screen, (see its documentation there for details). We anticipate
1339 making this automatic in a future release.
1341 New 'G' key binding to trigger mail refresh (G == "Get new mail")
1343 The 'G' key works wherever '=' works. Before refreshing the screen
1344 it calls an external program that can be used to poll email servers,
1345 run notmuch new and setup specific tags for the new emails. The
1346 script to be called should be configured with the "Notmuch Poll
1347 Script" setting in the customize interface. This script will
1348 typically invoke "notmuch new" and then perhaps several "notmuch
1351 Implement emacs message display with the JSON output from notmuch.
1353 This is much more robust than the previous implementation, (where
1354 some HTML mails and mail quoting the notmuch code with the delimiter
1355 characters in it would cause the parser to fall over).
1357 Better handling of HTML messages and MIME attachments (inline images!)
1359 Allow for any MIME parts that emacs can display to be displayed
1360 inline. This includes inline viewing of image attachments, (provided
1361 the window is large enough to fit the image at its natural size).
1363 Much more robust handling of HTML messages. Currently both text/plain
1364 and text/html alternates will be rendered next to each other. In a
1365 future release, users will be able to decide to see only one or the
1366 other representation.
1368 Each attachment now has its own button so that attachments can be
1369 saved individually (the 'w' key is still available to save all
1372 Customizable support for tidying of text/plain message content
1374 Many new functions are available for tidying up message
1375 content. These include options such as wrapping long lines,
1376 compressing duplicate blank lines, etc.
1378 Most of these are disabled by default, but can easily be enabled by
1379 clicking the available check boxes under the "Notmuch Show Insert
1380 Text/Plain Hook" within the notmuch customize screen.
1382 New support for searchable citations (even when hidden)
1384 When portions of overly-long citations are hidden, the contents of
1385 these citations will still be available for emacs' standard
1386 "incremental search" functions. When the search matches any portion
1387 of a hidden citation, the citation will become visible temporarily
1388 to display the search result.
1390 More flexible handling of header visibility
1392 As an answer to complaints from many users, the To, Cc, and Date
1393 headers of messages are no longer hidden by default. For those users
1394 that liked that these were hidden, a new "Notmuch Messages Headers
1395 Visible" option in the customize interface can be set to nil. The
1396 visibility of headers can still be toggled on a per-message basis
1397 with the 'h' keybinding.
1399 For users that don't want to see some subset of those headers, the
1400 new "Notmuch Message Headers" variable can be customized to list
1401 only those headers that should be present in the display of a message.
1403 The Return key now toggles message visibility anywhere
1405 Previously this worked only on the first summary-line of a message.
1407 Customizable formatting of search results
1409 The user can easily customize the order, width, and formatting of
1410 the various fields in a "notmuch search" buffer. See the "Notmuch
1411 Search Result Format" section of the customize interface.
1413 Generate nicer names for search buffers when using a saved search.
1415 Add a notmuch User-Agent header when sending mail from notmuch/emacs.
1417 New keybinding (M-Ret) to open all collapsed messages in a thread.
1421 Provide a new NOTMUCH_SORT_UNSORTED value for queries
1423 This can be somewhat faster when sorting simply isn't desired. For
1424 example when collecting a set of messages that will all be
1425 manipulated identically, (adding a tag, removing a tag, deleting the
1426 messages), then there's no advantage to sorting the messages by
1431 Fix to compile against GMime 2.6
1433 Previously notmuch insisted on being able to find GMime 2.4, (even
1434 though GMime 2.6 would have worked all along).
1436 Fix configure script to accept (and ignore) various standard options.
1438 For example, those that the Gentoo build scripts expect configure to
1439 accept are now all accepted.
1443 A large number of new tests for the many new features.
1445 Better display of output from failed tests.
1447 Now shows failures with diff rather than forcing the user to gaze at
1448 complete actual and expected output looking for deviation.
1450 Notmuch 0.2 (2010-04-16)
1451 ========================
1452 This is the second release of the notmuch mail system, with actual
1453 detailed release notes this time!
1455 This release consists of a number of minor new features that make
1456 notmuch more pleasant to use, and a few fairly major bug fixes.
1458 We didn't quite hit our release target of "about a week" from the 0.1
1459 release, (0.2 is happening 11 days after 0.1), but we hope to do
1460 better for next week. Look forward to some major features coming to
1461 notmuch in subsequent releases.
1467 Better guessing of From: header.
1469 Notmuch now tries harder to guess which configured address should be
1470 used as the From: line in a "notmuch reply". It will examine the
1471 Received: headers if it fails to find any configured address in To:
1472 or Cc:. This allows it to often choose the correct address even when
1473 replying to a message sent to a mailing list, and not directly to a
1476 Make "notmuch count" with no arguments count all messages
1478 Previously, it was hard to construct a search term that was
1479 guaranteed to match all messages.
1481 Provide a new special-case search term of "*" to match all messages.
1483 This can be used in any command accepting a search term, such as
1484 "notmuch search '*'". Note that you'll want to take care that the
1485 shell doesn't expand * against the current files. And note that the
1486 support for "*" is a special case. It's only meaningful as a single
1487 search term and loses its special meaning when combined with any
1490 Automatically detect thread connections even when a parent message is
1493 Previously, if two or more message were received with a common
1494 parent, but that parent was not received, then these messages would
1495 not be recognized as belonging to the same thread. This is now fixed
1496 so that such messages are properly connected in a thread.
1500 Fix potential data loss in "notmuch new" with SIGINT
1502 One code path in "notmuch new" was not properly handling
1503 SIGINT. Previously, this could lead to messages being removed from
1504 the database (and their tags being lost) if the user pressed
1505 Control-C while "notmuch new" was working.
1507 Fix segfault when a message includes a MIME part that is empty.
1509 Fix handling of non-ASCII characters with --format=json
1511 Previously, characters outside the range of 7-bit ASCII were
1512 silently dropped from the JSON output. This led to corrupted display
1513 of utf-8 content in the upcoming notmuch web-based frontends.
1515 Fix headers to be properly decoded in "notmuch reply"
1517 Previously, the user might see:
1519 Subject: Re: =?iso-8859-2?q?Rozlu=E8ka?=
1523 Subject: Re: Rozlučka
1525 The former text is properly encoded to be RFC-compliant SMTP, will
1526 be sent correctly, and will be properly decoded by the
1527 recipient. But the user trying to edit the reply would likely be
1528 unable to read or edit that field in its encoded form.
1530 Emacs client features
1531 ---------------------
1532 Show the last few lines of citations as well as the first few lines.
1534 It's often the case that the last sentence of a citation is what is
1535 being replied to directly, so the last few lines are often much more
1536 important. The number of lines shown at the beginning and end of any
1537 citation can be configured, (notmuch-show-citation-lines-prefix and
1538 notmuch-show-citation-lines-suffix).
1540 The '+' and '-' commands in the search view can now add and remove
1543 Selective bulk tagging is now possible by selecting a region of
1544 threads and then using either the '+' or '-' keybindings. Bulk
1545 tagging is still available for all threads matching the current
1546 search with the '*' binding.
1548 More meaningful buffer names for thread-view buffers.
1550 Notmuch now uses the Subject of the thread as the buffer
1551 name. Previously it was using the thread ID, which is a meaningless
1554 Provide for customized colors of threads in search view based on tags.
1556 See the documentation of notmuch-search-line-faces, (or us "M-x
1557 customize" and browse to the "notmuch" group within "Applications"
1558 and "Mail"), for details on how to configure this colorization.
1560 Build-system features
1561 ---------------------
1562 Add support to properly build libnotmuch on Darwin systems (OS X).
1564 Add support to configure for many standard options.
1566 We include actual support for:
1568 --includedir --mandir --sysconfdir
1570 And accept and silently ignore several more:
1572 --build --infodir --libexecdir --localstatedir
1573 --disable-maintainer-mode --disable-dependency-tracking
1575 Install emacs client in "make install" rather than requiring a
1576 separate "make install-emacs".
1578 Automatically compute versions numbers between releases.
1580 This support uses the git-describe notation, so a version such as
1581 0.1-144-g43cbbfc indicates a version that is 144 commits since the
1582 0.1 release and is available as git commit "43cbbfc".
1584 Add a new "make test" target to run the test suite and actually verify
1587 Notmuch 0.1 (2010-04-05)
1588 ========================
1589 This is the first release of the notmuch mail system.
1591 It includes the libnotmuch library, the notmuch command-line
1592 interface, and an emacs-based interface to notmuch.
1594 Note: Notmuch will work best with Xapian 1.0.18 (or later) or Xapian
1595 1.1.4 (or later). Previous versions of Xapian (whether 1.0 or 1.1) had
1596 a performance bug that made notmuch very slow when modifying
1597 tags. This would cause distracting pauses when reading mail while
1598 notmuch would wait for Xapian when removing the "inbox" and "unread"
1599 tags from messages in a thread.
