If the private index file matches a previously known revision of the
database, we can update the index incrementally using the recorded
lastmod counter. This is typically much faster than a full update,
although it could be slower in the case of large changes to the
database.
The "git-read-tree HEAD" is also a bottleneck, but unfortunately
sometimes is needed. Cache the index checksum and hash to reduce the
number of times the operation is run. The overall design is a
simplified version of the PrivateIndex class.
Unlike the (current) infix query parser provided by Xapian, the
notmuch specific sexp query parser supports prefixed wildcard queries,
so use those. In addition to being somewhat faster, this avoids
needing to escape all of the user's tags to pass via the shell.
Although the code required to support both new and old environment
variables is small, it complicates the semantics of configuration, and
make the documentation harder to follow.
Having notmuch-show-next-thread return non-nil on success and nil on
failure makes it easier for users to interact with notmuch via elisp.
This commit changes notmuch-search-show-thread too since the return
value of notmuch-show-next-thread depends on notmuch-search-show-thread.
Amended by db: fix whitespace in T450-emacs-show
This is a bit more involved than replacing the use of
notmuch_database_open_verbose, as we have to effectively inline the
definition of notmuch_database_open.
The actual content type of `application/octet-stream` is up to content
type detection of the reader, and thus may not be stable across
implementations or versions. This showed up when
fd46fc19 ("emacs: document/defcustom notmuch-multipart/alternative-discouraged", 2022-05-14)
introduced a test for omitting a part of type `text/html` because it
expected a part of type `application/octet-stream` to remain in place,
i.e. a part of "unstable type". In particular, tests with `fd46fc19`
would succeed on RHEL/EPEL but fail on all current Fedoras with

Fix this by giving that message a specicific type of `text/x-diff` in
the test corpus, and adjust all affected test outputs.

Amended-by: db, fix some trailing whitespace
This variable is important for people who want to change the default
behaviour when displaying multipart/alternative messages. Previously
it was undocumented. Add a defcustom to help users and copy some
documentation from the wiki. The usual machinery of re-using
docstrings is a bit tricky to use here because it mangles the example
lisp code, and the link to the info node should not be in e.g. the
html page.
Add a simple test to make sure the switch from defvar to defcustom did
not break something obvious.
The extra machinery to check for the actual output format is justified
by the possibility that distros may patch this newer output format
into older versions of gmime.

Since Xapian does not preserve quotes when passing the subquery to a
field processor, we have to make a guess as to what the user
intended. Here the added assumption is that a string surrounded by
parens is not intended to be a phrase.
test_require_external prereq has to move to test-lib-common.sh, and
the new shell functions print_emacs_header and time_emacs are provided.
The somewhat indirect way of printing the output is to avoid the extra
"" present on string values from emacsclient.
T310-emacs is one of the largest and longest running sets of
tests. Splitting out the tagging operations will help maintainability
as well as potentially improve the parallel running time of the test
suite. Some slowdown in running the tests sequentially may result
since there is repeated setup.
This allows sharing more variable settings between the (correctness)
tests and the performance-tests. Unfortunately it seems a bit tricky
to move settings to test-lib-common.sh, as that is sourced late in
test-lib.sh, and moving it earlier breaks things.
In most cases used printf %s ... instead.
echo -n > file lines to create empty / truncate files were
changed to : > file lines, like done in in test-lib-emacs.sh
And one echo -n " " replaced with use of sed "s/^/ /" in next line.
The idea is to do as little parsing and modification of the delivered
message as possible. Luckily the position of the "envelope header"
lets us escape it by replacing the first 5 characters of the stream
with a regular header name (with ':').
This particular message is not recognized by notmuch as mail, but is
fine according to e.g. mutt. The trigger for this bad behaviour seems
to be a second "From " ocurring at the beginning of the line but
inside an attachment.
As of notmuch 0.34.2 [1], the python-cffi bindings make available the
configuration from both a config file and the database when accessing
Database.config like a dictionary. It is therefore confusing that the
iterator operations only work on the configuration information stored
in the database.

This changes makes the sexp query parser consistent with the infix one
in ignoring trailing '/'. Here we do a bit better and ignore any
number of trailing '/'.
This is mainly to make sure we get trailing / removal correct. Also
add regression test for path: in the infix parser matching the
existing one for folder:.
This resolves an old bug reported by David Edmondson in 2014. The fix
is only needed for the "boolean" case, as probabilistic / phrase
searching already ignores punctuation.
This fix is only for the infix (xapian provided) query parser.

This duplicates the bug reported in [1], as well as adding some simple
regression tests for 'path' and 'folder' searches which were
previously missing for sexp syntax.
[1]: id:cunoasuolcv.fsf@gargravarr.hh.sledj.net
In [1], David Edmondson observed that the trailing / added by many
completion mechanisms causes path searches to silently fail. This
test reproduces that bug for both `path:' and `folder:' searches.

It is fragile to encode the generated names into tests, as it makes
tests break when e.g. new tests are added. There is a possibility
that this will hide certain failures; in that case meaningful filenames
should be chosen for the generated messages.
These are loosely modelled on the tests just above for date ranges,
since the error conditions are similar. Some ideas also borrowed from
T570-revision-tracking.
The default argument processing overlaps somewhat with what is already
done in _notmuch_date_strings_to_query, but we can give more specific
error messages for the s-expression context.
The extra generality of _sexp_parse_range will be useful when we
implement additional range prefixes (at least 'lastmod' is needed).
This fixes the bug reported by dkg in [1]. The movement of the call to
n-m-setup-message-for-saving is so the cleanup of Fcc headers happens
in the encoded version (otherwise Fcc headers may be saved to disk).

Based on the method outlined by Daniel Kahn Gillmor in
id:87k1zm225v.fsf@fifthhorseman.net. With a delay of 0.2 seconds the
test becomes flaky on my machine. With a 1 second delay it fails
consistently for more than 1600 iterations.
