Tamas Szakaly points out [1] that the bug fixed in 51b073c still
exists in at least one place. This change follows the suggestion of
[2] and creates a block scope temporary std::string to avoid the rules
of iterators temporaries.

We generally do not support mbox files, but for historical reasons
we've supported single-message mbox files, with a deprecation
message. We've tried dropping the support altogether, but backed out
of it because we'd need to stop indexing them, while keeping support
for previously indexed files. This would be more complicated than
simply supporting single-message mbox files. Therefore, drop the
deprecation message, and just silently accept single-message mboxes.
Currently, if a From-header is of the form:
"" <address@example.com>
the empty string will be treated as a valid real-name, and the entry
in the search results will be empty.
The new behavior here is that we treat an empty real-name field as if
it were null, so that the email address will be used in the search
results instead.

Previously, it was necessary to link new messages to children to work
around some (though not all) problems with the old metadata-based
approach to stored thread IDs. With ghost messages, this is no longer
necessary, so don't bother with child linking when ghost messages are
in use.
This updates the thread linking code to use ghost messages instead of
user metadata to link messages into threads.
In contrast with the old approach, this is actually correct.
Previously, thread merging updated only the thread IDs of message
documents, not thread IDs stored in user metadata. As originally
diagnosed by Mark Walters [1] and as demonstrated by the broken
T260-thread-order test, this can cause notmuch to fail to link
messages even though they're in the same thread. In principle the old
approach could have been fixed by updating the user metadata thread
IDs as well, but these are not indexed and hence this would have
required a full scan of all stored thread IDs. Ghost messages solve
this problem naturally by reusing the exact same thread ID and message
ID representation and indexing as regular messages.
Furthermore, thanks to this greater symmetry, ghost messages are also
algorithmically simpler. We continue to support the old user metadata
format, so this patch can't delete any code, but when we do remove
support for the old format, several functions can simply be deleted.
[1] id:8738h7kv2q.fsf@qmul.ac.uk
This updates the message abstraction to support ghost messages: it
adds a message flag that distinguishes regular messages from ghost
messages, and an internal function for initializing a newly created
(blank) message as a ghost message.
In the interest of robustness, avoid undefined behavior of
sortable_unserialise if the date value is missing. This shouldn't
happen now, but ghost messages will have blank date values.
This moves the code to retrieve and clear the metadata thread ID out
of _notmuch_database_link_message into its own function. This will
simplify future changes.
Previously, this was performed by notmuch_database_add_message. This
happens to be the only caller currently (which is why this was safe),
but we're about to introduce more callers, and it makes more sense to
put responsibility for ID compression in the lower-level function
rather than requiring each caller to handle it.
In Xapian, closing a database implicitly aborts any outstanding
transaction and commits changes. For historical reasons,
notmuch_database_close had grown to almost, but not quite duplicate
this behavior. Before closing the database, it would explicitly (and
unnecessarily) commit it. However, if there was an outstanding
transaction (ie atomic section), commit would throw a Xapian
exception, which notmuch_database_close would unnecessarily print to
stderr, even though notmuch_database_close would ultimately abort the
transaction anyway when it called close.
This patch simplifies notmuch_database_close to explicitly abort any
outstanding transaction and then just call Database::close. This
works for both read-only and read/write databases, takes care of
committing changes, unifies the exception handling path, and codifies
aborting outstanding transactions. This is currently the only way to
abort an atomic section (and may remain so, since it would be
difficult to roll back things we may have cached from rolled-back
modifications).
as stated in thread.cc:115
/* Construct an authors string from matched_authors_array and
* authors_array. The string contains matched authors first, then
* non-matched authors (with the two groups separated by '|'). Within
* each group, authors are listed in date order. */
this is, however, not reflected in the public API documentation in
notmuch.h:970. This patch a paragraph explaining how | separates the
group of authors of messages matching the query and those of messages
that do not, but are still contained in the thread.
48db8c8 introduced a disagreement between when
notmuch_database_needs_upgrade returned TRUE and when
notmuch_database_upgrade actually performed an upgrade. As a result,
if a database had a version less than 3, but no new features were
required, notmuch new would call notmuch_database_upgrade to perform
an upgrade, but notmuch_database_upgrade would return immediately
without updating the database version. Hence, the next notmuch new
would do the same, and so on.
Fix this by ensuring that the upgrade-required logic is identical
between the two.
Previously, there was no protection against a caller invoking an
operation on an old database version that would effectively corrupt
the database by treating it like a newer version.
According to notmuch.h, any caller that opens the database in
read/write mode is supposed to check if the database needs upgrading
and perform an upgrade if it does. This would protect against this,
but nobody (even the CLI) actually does this.
However, with features, it's easy to protect against incompatible
operations on a fine-grained basis. This lightweight change allows
callers to safely operate on old database versions, while preventing
specific operations that would corrupt the database with an
informative error message.
Commit 567bcbc2 introduced support for storing various headers in
document values. However, doing so in a backwards-compatible way
meant that genuinely empty header values could not be distinguished
from the old behavior of not storing the headers at all, so these
required parsing the original message.
Now that we have database features, new databases can declare that all
messages have header values, so if we have this feature flag, we can
use the stored header value even if it's the empty string.
This requires slight cleanup to notmuch_message_get_header, since the
code previously couldn't distinguish between empty headers and headers
that are never stored in the database (previously this distinction
didn't matter).
Previously, some parts of upgrade didn't report progress and for
others it was possible for the progress meter to restart at 0 part way
through the upgrade because each stage was reported separately.
Fix this by computing the total amount of work that needs to be done
up-front and updating completed work monotonically.
Rather than potentially making multiple passes over the same type of
data in the database, reorganize upgrade around each type of data that
may be upgraded. This eliminates code duplication, will make
multi-version upgrades faster, and will let us improve progress
reporting.
Previously, we had database version information hard-coded in the
upgrade code. Slightly re-organize the upgrade process around the set
of new database features to be enabled by the upgrade.
Previously, the upgrade was organized as two passes -- an upgrade
pass, and a separate cleanup pass -- so the database was always in a
valid state. This change substantially simplifies this code by
performing the upgrade in a transaction and combining both passes in
to one. This 1) eliminates a lot of duplicate code between the
passes, 2) speeds up the upgrade process, 3) makes progress reporting
more accurate, 4) eliminates the potential for stale data if the
upgrade is interrupted during the cleanup pass, and 5) makes it easier
to reason about the safety of the upgrade code.
Previously, our database schema was versioned by a single number.
Each database schema change had to occur "atomically" in Notmuch's
development history: before some commit, Notmuch used version N, after
that commit, it used version N+1. Hence, each new schema version
could introduce only one change, the task of developing a schema
change fell on a single person, and it all had to happen and be
perfect in a single commit series. This made introducing a new schema
version hard. We've seen only two schema changes in the history of
Notmuch.
This commit introduces database schema version 3; hopefully the last
schema version we'll need for a while. With this version, we switch
from a single version number to "features": a set of named,
independent aspects of the database schema.
Features should make backwards compatibility easier. For many things,
it should be easy to support databases both with and without a
feature, which will allow us to make upgrades optional and will enable
"unstable" features that can be developed and tested over time.
Features also make forwards compatibility easier. The features
recorded in a database include "compatibility flags," which can
indicate to an older version of Notmuch when it must support a given
feature to open the database for read or for write. This lets us
replace the old vague "I don't recognize this version, so something
might go wrong, but I promise to try my best" warnings upon opening a
database with an unknown version with precise errors. If a database
is safe to open for read/write despite unknown features, an older
version will know that and issue no message at all. If the database
is not safe to open for read/write because of unknown features, an
older version will know that, too, and can tell the user exactly which
required features it lacks support for.
According to RFC2822 References and In-Reply-To headers are supposed
to contain one or more Message-IDs, however older RFC822 allowed
almost any content. When both References and In-Reply-To headers ends
with something else that a Message-ID (see e.g. [1]), the thread
structure presented by notmuch is incorrect. The reason is that
notmuch treats this case as if the email contained no "replyto"
information (see _notmuch_database_link_message_to_parents).
This patch changes the parse_references() function to return the last
valid Message-ID encountered rather than NULL resulting from the last
hunk of text not being the Message-ID.

Previously, we invalidated stored message metadata in
_notmuch_message_add_term and _notmuch_message_remove_term, but not in
_notmuch_message_gen_terms. This doesn't currently result in any bugs
because of our limited uses of _notmuch_message_gen_terms, but it may
could cause trouble in the future.
As noted in devel/STYLE, every private library function should start
with _notmuch. This patch corrects function naming that did not adhere
to this style in lib/notmuch-private.h. In particular, the old function
names that now begin with _notmuch are
notmuch_sha1_of_file

notmuch_database_close may fail in Xapian ->flush() or ->close(), so
report the status. Similarly for notmuch_database_destroy which calls
close.
This is required for notmuch insert to report error status if message
indexing failed.
This adds a 100 termpos gap between all phrases indexed by
_notmuch_message_gen_terms. This fixes a bug where terms from the end
of one header and the beginning of another header could match together
in a single phrase and a separate bug where term positions of
un-prefixed terms overlapped.
This fix only affects newly indexed messages. Messages that are
already indexed won't benefit from this fix without re-indexing, but
the fix won't make things any worse for existing messages.
Previously, we indexed the name and address parts of from/to headers
with two calls to _notmuch_message_gen_terms. In general, this
indicates that these parts are separate phrases. However, because of
an implementation quirk, the two calls to _notmuch_message_gen_terms
generated adjacent term positions for the prefixed terms, which
happens to be the right thing to do in this case, but the wrong thing
to do for all other calls. Furthermore, _notmuch_message_gen_terms
produced potentially overlapping term positions for the un-prefixed
copies of the terms, which is simply wrong.
This change indexes both the name and address in a single call to
_notmuch_message_gen_terms, indicating that they should be part of a
single phrase. This masks the problem with the un-prefixed terms
(fixing the two known-broken tests) and puts us in a position to fix
the unintentionally phrases generated by other calls to
_notmuch_message_gen_terms.
This is effectively a revert of

lib: drop support for single-message mbox files
The intention was to drop support for indexing new single-message mbox
files (and whether that was a good idea in the first place is
arguable). However this inadvertently broke support for reading
headers from previously indexed single-message mbox files, which is
far worse.
Distinguishing between the two cases would require more code than
simply bringing back support for single-message mbox files.
The notmuch library includes a full blown message header parser. Yet
the same message headers are parsed by gmime during indexing. Switch
to gmime parsing completely.
These are the main changes:
* Gmime stops header parsing at the first invalid header, and presumes
the message body starts from there. The current parser is quite
liberal in accepting broken headers. The change means we will be
much pickier about accepting invalid messages.
* The current parser converts tabs used in header folding to
spaces. Gmime preserve the tabs. Due to a broken python library used
in mailman, there are plenty of mailing lists that produce headers
with tabs in header folding, and we'll see plenty of tabs. (This
change has been mitigated in preparatory patches.)
* For pure header parsing, the current parser is likely faster than
gmime, which parses the whole message rather than just the
headers. Since we parse the message and its headers using gmime for
indexing anyway, this avoids and extra header parsing round when
adding new messages. In case of duplicate messages, we'll end up
parsing the full message although just headers would be
sufficient. All in all this should still speed up 'notmuch new'.
* Calls to notmuch_message_get_header() may be slightly slower than
previously for headers that are not indexed in the database, due to
parsing of the whole message. Within the notmuch code base, notmuch
reply is the only such user.
We've supported mbox files containing a single message for historical
reasons, but the support has been deprecated, with a warning message
while indexing, since Notmuch 0.15. Finally drop the support, and
consider all mbox files non-email.
In xapian terms, convert folder: prefix from probabilistic to boolean
prefix, matching the paths, relative from the maildir root, of the
message files, ignoring the maildir new and cur leaf directories.
folder:foo matches all message files in foo, foo/new, and foo/cur.
folder:foo/new does *not* match message files in foo/new.
folder:"" matches all message files in the top level maildir and its
new and cur subdirectories.
This change constitutes a database change: bump the database version
and add database upgrade support for folder: terms. The upgrade also
adds path: terms.
Finally, fix the folder search test for literal folder: search, as
some of the folder: matching capabilities are lost in the
probabilistic to boolean prefix change.
The path: prefix is a literal boolean prefix matching the paths,
relative from the maildir root, of the message files.
path:foo matches all message files in foo (but not in foo/new or
foo/cur).
path:foo/new matches all message files in foo/new.
path:"" matches all message files in the top level maildir.
path:foo/** matches all message files in foo and recursively in all
subdirectories of foo.
path:** matches all message files recursively, i.e. all messages.
Clarify that using the directory after destroying the corresponding
database is not permitted.
This is implicit in the description of notmuch_database_destroy, but
it doesn't hurt to be explicit, and we do express similar "ownership"
relationships at other places in the docs.
Currently if a Xapian exception happens in notmuch_message_get_header,
the exception is not caught leading to crash. In
notmuch_message_get_date the exception is caught, but an internal error
is raised, again leading to crash.
This patch fixes the error handling by making both functions catch the
Xapian exceptions, print an error and return NULL or 0.
The 'notmuch->exception_reported' is also set, as is done elsewhere,
even if I don't really get the idea of that field.

With some combination of clang and talloc, not using the return value
of talloc_steal() produces a warning. Ignore it, as talloc_steal() has
no failure modes per documentation.
This version of the library introduces LIBNOTMUCH_CHECK_VERSION and
the *_VERSION macros. Bumping the version number is also necessary to
make the comment on LIBNOTMUCH_CHECK_VERSION no longer a lie.
This makes it clear that these macros refer to the *library* version,
and not to the notmuch application-level release. Since there are no
consumers of these macros yet, this is now or never.
We have two distinct "library version" numbers: the soname version and
the version macros. We need both for different reasons: the version
macros enable easy compile-time version detection (and conditional
compilation), while the soname version enables runtime version
detection (which includes the version checking done by things like the
Python bindings).
However, currently, these two version numbers are different, which is
unnecessary and can lead to confusion (especially in things like
Debian, which include the soname version in the package name). This
patch makes them the same by bumping the version macros up to agree
with the soname version.
(We should probably keep the version number in just one place so they
can't get out of sync, but that can be done in another patch.)
Unfortunately old versions of GCC and clang do not provide byte order
macros, so we re-invent them.
If UTIL_BYTE_ORDER is not defined or defined to 0, we fall back to
macros supported by recent versions of GCC and clang
Previously PLATFORM_BYTE_ORDER and IS_LITTLE_ENDIAN were not defined,
so the little endian code was always compiled in.
This will have the effect that the "SHA1s" on big endian architectures
will change (i.e. become actual sha1s). So someone re-indexing their
database could conceivable lose tags on messages without a message-id
header.
In case previous notmuch compact has been interrupted there is old
work-in-progress database compact directory partially filled. Remove
it just before starting to fill the directory with new files.
It is less error prone and window of failure opportunity is smaller
if the old (backup) database is always renamed (instead of sometimes
rmtree'd) before new (compacted) database is put into its place.
Finally rmtree() old database in case old database backup is not kept.
catch Xapian::Error in compact code in lib/database.cc to be consistent
with other code in addition to not making software crash on uncaught
other Xapian error.
There have been some plans for making build incompatible changes to
the library API. This is inconvenient, but it is much more so without
a way to easily conditional build against multiple versions of
notmuch.
The macro has been lifted from glib.
The extra path component added by the lib is a magic value that the
caller just has to know. This is demonstrated by the current code,
which indeed has "xapian.old" both sides of the interface. Use the
backup path provided by the lib caller verbatim, without adding
anything to it.
The queries don't really work after a database is closed, and we would
like them to be freed if the database is destroyed.

notmuch_message_tags_to_maildir_flags() unconditionally moves messages from
maildir directory "new/" to maildir directory "cur/", which makes messages lose
their "new" status in the MUA. However some users want to keep this "new"
status after, for instance, an auto-tagging of new messages.
However, as Austin mentioned and according to the maildir specification,
messages living in "new/" are not allowed to have flags, even if mutt allows it
to happen. For this reason, this patch prevents moving messages from "new/" to
"cur/", only if no flags have to be changed. It's hopefully enough to satisfy
mutt (and maybe other MUAs showing the "new" status) users checking the "new"
status.

lib: Add support for automatically excluding tags from queries
changed visibility of struct _notmuch_string_list for the same reason, and

Author: Mark Walters <markwalters1009@gmail.com>
Date: Thu Mar 1 22:30:38 2012 +0000
lib: Add the exclude flag to notmuch_query_search_threads
split the struct _notmuch_string_list and its typedef
notmuch_string_list_t as a way to make a forward declaration for
_notmuch_thread_create().
The subtle difference was that the struct definition now had 'visible'
in it, while the typedef didn't, and it was within the #pragma GCC
visibility push(hidden) block. This went unnoticed, as the then common
versions of clang didn't care about this.
A later change in clang (I did not dig into when this change was
introduced) caused the following error:
CXX -O2 lib/database.o
In file included from lib/database.cc:21:
In file included from ./lib/database-private.h:33:

make: *** [lib/database.o] Error 1
This is slightly misleading due to the reference to the #pragma. The
real culprit is the typedef within the #pragma.
We could just add 'visible' to the typedef, or move the typedef
outside of the #pragma, and be done with it, but juggle the
declarations a bit to accommodate moving the typedef back with the
struct, and keep the visibility attribute in one place.
The problem was originally reported by Simonas Kazlauskas
<s@kazlauskas.me> in id:20130418102507.GA23688@godbox but I was only
able to reproduce and investigate now that I upgraded clang.
notmuch_message_get_header started returning some headers straight
from the database in 567bcbc, but this comment explicitly claimed all
headers were read from the message file.
Add NOTMUCH_EXCLUDE_FLAG to notmuch_exclude_t so that it can
cover all four values of search --exclude in the cli.
Previously the way to avoid any message being marked excluded was to
pass in an empty list of excluded tags: since we now have an explicit
option we might as well honour it.
The enum is in a slightly strange order as the existing FALSE/TRUE
options correspond to the new
NOTMUCH_EXCLUDE_FLAG/NOTMUCH_EXCLUDE_TRUE options so this means we do
not need to bump the version number.
Indeed, an example of this is that the cli count and show still use
FALSE/TRUE and still work.
Presently, the code which finds the parent of a message as it is being
added to the database assumes that the first Message-ID-like substring
of the In-Reply-To header is the parent Message ID. Some mail clients,
however, put stuff other than the Message-ID of the parent in the
In-Reply-To header, such as the email address of the sender of the
parent. This can fool notmuch.
The updated algorithm prefers the last Message ID in the References
header. The References header lists messages oldest-first, so the last
Message ID is the parent (RFC2822, p. 24). The References header is
also less likely to be in a non-standard
syntax (http://cr.yp.to/immhf/thread.html,
http://www.jwz.org/doc/threading.html). In case the References header
is not to be found, fall back to the old behavior.

Previously, getting the list of all messages in a thread required
recursively traversing the thread's message hierarchy, which was both
difficult and resulted in messages being out of order. This adds a
public function to retrieve an iterator over all of the messages in a
thread in oldest-first order.
Previously, thread.cc built up a list of all messages, then
proceeded to tear it apart to transform it into a list of
top-level messages. Now we simply build a new list of top-level
messages.
This simplifies the interface to _notmuch_message_add_reply,
eliminates the pointer acrobatics from
_resolve_thread_relationships, and will enable us to do things
with the list of all messages in the following patches.
Previously, there were various opportunities for memory leaks in the
error-handling paths of this function. Use a local talloc context and
some reparenting to make eliminate these leaks, while keeping the
control flow simple.
Using char instead of int allows for simpler definitions of the
DOCIDSET macros so the code is easier to understand and consistent with
respect to memory-usage. Estimated reduction of memory-usage for
bitmap about 8 times.
Apparently as of GMime 2.4, you don't need to call
internet_address_list_destroy anymore, but you still need to call
g_object_unref (from the GMime Changelog).
On the medium performance corpus, valgrind shows "possibly lost"
leakage in "notmuch new" dropping from 7M to 300k.
The message->headers hash table values get data returned by
g_mime_utils_header_decode_text ().
The pointer returned by g_mime_utils_header_decode_text is from the
following line in rfc2047_decode_tokens
return g_string_free (decoded, FALSE);
The docs for g_string_free say
Frees the memory allocated for the GString. If free_segment is TRUE
it also frees the character data. If it's FALSE, the caller gains
ownership of the buffer and must free it after use with g_free().
The remaining frees and allocations referencing to message->headers hash
values have been changed to use g_free and g_malloc functions.
This combines and completes the changes started by David Bremner.
Previously, we would treat multi-message mboxes as one giant email,
which, besides the obvious incorrect indexing, often led to
out-of-memory errors for archival mboxes. Now we explicitly reject
multi-message mboxes. For historical reasons, we retain support for
single-message mboxes, but official deprecate this behavior.
Add a custom value range processor to enable date and time searches of
the form date:since..until, where "since" and "until" are expressions
understood by the previously added date/time parser, to restrict the
results to messages within a particular time range (based on the Date:
header).
If "since" or "until" describes date/time at an accuracy of days or
less, the values are rounded according to the accuracy, towards past
for "since" and towards future for "until". For example,
date:november..yesterday would match from the beginning of November
until the end of yesterday. Expressions such as date:today..today
means since the beginning of today until the end of today.
Open-ended ranges are supported (since Xapian 1.2.1), i.e. you can
specify date:..until or date:since.. to not limit the start or end
date, respectively.
CAVEATS:
Xapian does not support spaces in range expressions. You can replace
the spaces with '_', or (in most cases) '-', or (in some cases) leave
the spaces out altogether.
Entering date:expr without ".." (for example date:yesterday) will not
work as you might expect. You can achieve the expected result by
duplicating the expr both sides of ".." (for example

Open-ended ranges won't work with pre-1.2.1 Xapian, but they don't
produce an error either.

OpenBSD's build flags are identical to FreeBSD, except that libraries
need to be explicitly linked against libc. No code changes are
necessary.

Fix the COERCE_STATUS macro to handle _internal_error being declared
as void function.
Note that the function _internal_error does not return. Evaluating to
NOTMUCH_STATUS_SUCCESS is done purely to appease the compiler.

The API documentation (notmuch.h) states that the parameter may be NULL,
but the implementation only checked the current element, potentially
dereferencing a NULL pointer in the process.

Previously, notmuch new only synchronized maildir flags to tags for
files with a maildir "info" part. Since messages in new/ don't have
an info part, notmuch would ignore them for flag-to-tag
synchronization.
This patch makes notmuch consider messages in new/ to be legitimate
maildir messages that simply have no maildir flags set. The most
visible effect of this is that such messages now automatically get the
unread tag.
Previously, we synchronized flags to tags for any message that looked
like it had maildir flags in its file name, regardless of whether it
was in a maildir-like directory structure. This was asymmetric with
tag-to-flag synchronization, which only applied to messages in
directories named new/ and cur/ (introduced by 95dd5fe5).
This change makes our interpretation stricter and addresses this
asymmetry by only synchronizing flags to tags for messages in
directories named new/ or cur/. It also prepares us to treat messages
in new/ as maildir messages, even though they lack maildir flags.
This way notmuch_message_maildir_flags_to_tags can call it. It makes
more sense for this to be just above all of the maildir
synchronization code rather than mixed in the middle.
Previously, if passed a filename with a directory that did not exist
in the database, _notmuch_message_remove_filename would needlessly
create that directory document. Fix it so that doesn't happen.
