Notmuch 0.6 (2011-07-01)
=======================
+
New, general features
---------------------
-Folder-based searching
+
+### Folder-based searching
Notmuch queries can now include a search term to match the
directories in which mail files are stored (within the mail
storage). The syntax is as follows:
- folder:<path>
For example, one might use things such as:
- folder:spam
+ folder:spam
folder:2011-*
folder:work/todo
this feature for all mail, the entire notmuch index will need to be
rebuilt as follows:
- notmuch dump > notmuch.dump
- # Backup, then remove notmuch database ($MAIL/.notmuch)
- notmuch new
- notmuch restore notmuch.dump
+ notmuch dump > notmuch.dump
+ # Backup, then remove notmuch database ($MAIL/.notmuch)
+ notmuch new
+ notmuch restore notmuch.dump
-Support for PGP/MIME

+ Both the command-line interface and the emacs-interface have new
support for PGP/MIME, detailed below. Thanks to Daniel Kahn Gillmor
and Jameson Graef Rollins for making this happen.
-New, automatic tags: "signed" and "encrypted"
+### New, automatic tags: "signed" and "encrypted"
These tags will automatically be applied to messages containing
multipart/signed and multipart/encrypted parts.
New command-line features
-------------------------
-Add new "notmuch show --verify" option for signature verification
+
+### Add new "notmuch show --verify" option for signature verification
This option instruct notmuch to verify the signature of
PGP/MIME-signed parts.
-Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
+### Add new "notmuch show --decrypt" and "notmuch reply --decrypt" options
This option instructs notmuch to decrypt PGP/MIME-encrypted parts.
Note that this feature currently requires gpg-agent and a passphrase entry
tool (e.g. pinentry-gtk or pinentry-curses).
-Proper nesting of multipart parts in "notmuch show" output
+### Proper nesting of multipart parts in "notmuch show" output
MIME parts are now display with proper nesting to reflect original
MIME hierarchy of a message. This allows clients to correctly
analyze the MIME structure, (such as, for example, determining to
which parts a signature part applies).
-Add new "notmuch show --part" option
+### Add new "notmuch show --part" option
This is a replacement for the older "notmuch part" command, (which
is now deprecated—it should still work as always, but is no longer
part, (such as --format=json for extracting a message part with JSON
formatting).
-Deprecate "notmuch search-tags", (in favor of "notmuch search --output=tags *")
+### Deprecate "notmuch search-tags" (in favor of "notmuch search --output=tags *")
The "notmuch search-tags" sub-command has been redundant since the
addition of the --output=tags option to "notmuch search". We now
Performance improvements
------------------------
-Faster searches (by doing fewer searches to construct threads)
+
+### Faster searches (by doing fewer searches to construct threads)
Whenever a user asks for search results as threads, notmuch first
performs a search for messages matching the query, then performs
Removing inefficiencies and redundancies in these secondary searches
results in a measured speedups of 1.5x for a typical search.
-Faster searches (by doing fewer passes to gather message data)
+### Faster searches (by doing fewer passes to gather message data)
Optimizing Xapian data access patterns (using a single pass to get
all message-document data rather than a pass for each data type)
of 2.5x for a search of all messages in his inbox (was 4.5s, now
1.8s). Thanks, Austin!
-Faster initial indexing
+### Faster initial indexing
More efficient indexing of new messages results in a measured
speedup of 1.4x for the initial indexing of 3 GB of mail (1h 14m
rather than 1h 46m). Thanks to Austin Clements and Michal Sojka.
-Make "notmuch new" faster for unchanged directories
+### Make "notmuch new" faster for unchanged directories
Optimizing to not do any further examinations of sub-directories
when the filesystem indicates that a directory is unchanged from the
New emacs-interface features
----------------------------
-Support for PGP/MIME (GnuPG)
+### Support for PGP/MIME (GnuPG)
Automatically indicate validity of signatures for multipart/signed
messages. Automatically display decrypted content for
multipart/encrypted messages. See the emacs variable
notmuch-crypto-process-mime for more information. Note that this
- needs gpg-agent and a pinentry tool just as the command line tools.
+ needs gpg-agent and a pinentry tool just as the command-line tools.
Also note there is no support SMIME yet.
-Output of pipe command is now displayed if pipe command fails
+### Output of pipe command is now displayed if pipe command fails
This is extremely useful in the common use case of piping a patch to
"git am". If git fails to cleanly merge the patch the error messages
from the failed merge are now clearly displayed to the user, (where
previously they were silently hidden from the user).
-User-selectable From address
+### User-selectable From address
A user can choose which configured email addresses should be used as
the From address whenever composing a new message. To do so, simply
the "Notmuch Always Prompt For Sender" option in the notmuch
customize group.
-Hiding of repeated subjects in collapsed thread view
+### Hiding of repeated subjects in collapsed thread view
In notmuch-show mode, if a collapsed message has the same subject as
its parent, the subject is not shown.
-
-Automatic detection and hiding of original message in top-posted message
+
+### Automatic detection and hiding of original message in top-posted message
When a message contains a line looking something like:
- ----- Original Message -----
+ ----- Original Message -----
emacs hides this and all subsequent lines as an "original message",
(allowing the user to click or press enter on the "original message"
button to display it again). This makes the handling of top-posted
citations work much like conventional citations.
-New hooks for running code when tags are modified
+### New hooks for running code when tags are modified
Some users want to perform additional actions whenever a particular
tag is added/removed from a message. This could be used to, for
tool. To facilitate this, two new hooks are added which can be
modified in the following settings of the notmuch customize group:
- Notmuch Before Tag Hook
- Notmuch After Tag Hook
+ Notmuch Before Tag Hook
+ Notmuch After Tag Hook
-New optional support for hiding some multipart/alternative parts
+### New optional support for hiding some multipart/alternative parts
Many emails are sent with redundant content within a
multipart/alternative group (such as a text/plain part as well as a
text/html part). Users can configure the setting:
- Notmuch Show All Multipart/Alternative Parts
+ Notmuch Show All Multipart/Alternative Parts
to "off" in the notmuch customize group to have the interface
automatically hide some part alternatives (such as text/html
because there's not yet a simple way to re-display such a hidden
part if it is not actually redundant with a displayed part.
-Better rendering of text/x-vcalendar parts
+### Better rendering of text/x-vcalendar parts
These parts are now displayed in a format suitable for use with the
emacs diary.
-Avoid getting confused by Subject and Author fields with newline characters
+### Avoid getting confused by Subject and Author fields with newline characters
Replacing all characters with ASCII code less than 32 with a question mark.
-Cleaner display of From line in email messages (remove double quotes,
-and drop "name" if it's actually just a repeat of the email address).

+ s1.union(s2)
+ s2 -= s1
+
+* Removed:
- s1, s2= set(msgs1), set(msgs2)
- s1.union(s2)
- s2 -= s1
+ - len(Messages()) as it exhausted the iterator.
+ Use len(list(Messages())) or
+ `Query.count_messages()` to get the length.

New build-system features
-------------------------
-Added support for building in a directory other than the source directory
+
+### Added support for building in a directory other than the source directory
This can be used with the widely-supported idiom of simply running
the configure script from some other directory:
- mkdir build
- cd build
- ../configure
- make
+ mkdir build
+ cd build
+ ../configure
+ make
-Fix to save configure options for future, implicit runs of configure
+### Fix to save configure options for future, implicit runs of configure
When a user updates the source (such as with "git pull") calling
"make" may cause an automatic re-run of the configure script. When
New test-suite feature
----------------------
-Binary for bash for running test suite now located via PATH.
+
+### Binary for bash for running test suite now located via PATH
The notmuch test suite requires a fairly recent version of bash (>=
bash 4). As some systems supply an older version of bash at
simply install bash >= 4 somewhere on $PATH before /bin and then use
the test suite.
-Support for testing output with a trailing newline.
+### Support for testing output with a trailing newline
Previously, some tests would fail to notice a difference in the
presence/absence of a trailing newline in a program output, (which
has led to bugs in the past). Now, carefully-written tests (using
- test_expect_equal_file rather than test_expect_equal) will detect
+ `test_expect_equal_file` rather than `test_expect_equal`) will detect
any change in the presence/absence of a trailing newline. Many tests
are updated to take advantage of this.
-Avoiding accessing user's $HOME while running test suite
+### Avoiding accessing user's $HOME while running test suite
The test suite now carefully creates its own HOME directory. This
allows the test suite to be run with no existing HOME directory, (as
General bug fixes
-----------------
-Output *all* files for "notmuch search --output=files"
+
+### Output *all* files for "notmuch search --output=files"
For the cases where multiple files have the same Message ID,
previous versions of notmuch would output only one such file. This
command is now fixed to correctly output all files.
-Fixed spurious search results from "overlapped" indexing of addresses
+### Fixed spurious search results from "overlapped" indexing of addresses
This fixed a bug where a search for:
- to:user@elsewhere.com
+ to:user@elsewhere.com
would incorrectly match a message sent:
- To: user@example,com, someone@elsewhere.com
+ To: user@example,com, someone@elsewhere.com
-Fix --output=json when search has no results
+### Fix --output=json when search has no results
A bug present since notmuch 0.4 had caused searches with no results
to produce an invalid json object. This is now fixed to cleanly
return a valid json object representing an empty array "[]" as
expected.
-fix the automatic detection of the From address for "notmuch reply"
-from the Received headers in some cases.
+### Fix the automatic detection of the From address for "notmuch reply" from the Received headers in some cases

Previous release of the notmuch library also exported some Xapian
C++ exception type symbols. These were never part of the library
Emacs-interface bug fixes
-------------------------
-Display any unexpected output or errors from "notmuch search" invocations
+
+### Display any unexpected output or errors from "notmuch search" invocations
Previously any misformatted output or trailing error messages were
silently ignored. This output is now clearly displayed. This fix was
very helpful in identifying and fixing the bug described below.
-Fix bug where some threads would be missing from large search results
+### Fix bug where some threads would be missing from large search results
When a search returned a "large" number of results, the emacs
interface was incorrectly dropping one thread every time the output
of the "notmuch search" process spanned the emacs read-buffer. This
is now fixed.
-Avoid re-compression of .gz files (and similar) when saving attachment
+### Avoid re-compression of .gz files (and similar) when saving attachment
Emacs was being too clever for its own good and trying to
re-compress pre-compressed .gz files when saving such attachments
(potentially corrupting the attachment). The emacs interface is
fixed to avoid this bug.
-Fix hiding of a message when a previously-hidden citation is visible
+### Fix hiding of a message when a previously-hidden citation is visible
Previously the citation would remain visible in this case. This is
fixed so that hiding a message hides all parts.
