Hopefully just a temporary measure.

I plan to add further architecture dependent checks, which makes this
preferable to directly calling dpkg-architecture.

Native compilation is kindof useless in the test suite because we
throw away the cache after every subtest. The test suite could in
principle share an eln cache within a given test file; for now try to
minimize the amount of native-compilation. There is an intermittent
bug where emacs loses track of its default-directory; I suspect (but
have no proof) that bug is related to native compilation and/or race
conditions. This patch seems to prevent that bug (or at least reduce
its frequency).

The presense of the blank lines between sections depends on the

According to discussion on
https://gitlab.gnome.org/GNOME/glib/-/issues/3078
it looks like upstream will stop supporting top of file comments.
It is questionable whether we really need this feature, but for now
update notmuch-config to simulate it.

As of Emacs 29.1, In-Reply-To is in the default value for
message-hidden-headers. We actually want to see that in the test
suite, so remove it again. To future proof the tests, fix a default
value for message-hidden-headers specifically for the test suite.
|
|
It is wasteful to remove a filename term when the whole message
document is about to be removed from the database. Profiling with perf
shows this takes a significant portion of the time when cleaning up
removed files in the database.
The logic of n_d_remove_message becomes a bit more convoluted here in
order to make the change minimal.
It is possible that this function can be further optimized, since the
expansion of filename terms into filenames is probably not needed
here.
|
|
It isn't really clear how this worked before. Traversing the terms of
a document after deleting it from the database seems likely to be
undefined behaviour at best
|
|
We generate output to stderr for BROKEN tests, which are not failures,
so tell the test runner not to fail because of output on stderr.
|
|
We put some effort into testing the built copy rather than some
installed copy. On the other hand for people like packagers, testing
the installed copy is also of interest.
When NOTMUCH_TEST_INSTALLED is set to a nonempty value, tests do not
require a built notmuch tree or running configure.
Some of the tests marked as broken when running against installed
notmuch are probably fixable.
|
|
python3 will work for many people, and reduce the friction to running
the tests without running configure first.
|
|
Messages can have empty bodies, but empty files are not messages.
|
|
When running the test suite without building first, it is desirable to
have the tests consider these variables being undefined as equivalent
to the feature not being present, and in particular for the tests not
to generate errors.

In the decade (!) since this corpus was last updated, the keyserver
network is essentially dead, and I have migrated gpg keys. Bump the
version number as a clean way of switching signatures. Also update the
instructions to suggest using "--locate-external-key" to download the
public key. By default this uses WKD, which is now supported for my
UID.

The ownership is implicit in the const declaration (I think!), but
that does not show up in the doxygen generated API docs.

According to my reading of RFC5322, there is an obsolete syntax for
Message-Id which permits folding whitespace (i.e. to be removed /
ignored by parsers). In [1] Paul Wise observed that notmuch removed
whitespace on indexing, but does not do any corresponding
normalization of queries. Mark the latter as a bug by adding a failing
test.

Py 3.12 finally pulled the plug on the `SafeConfigParser` class which
has been deprecated since py 3.2.
We use it in the legacy bindings only, so take the easy route of
importing `ConfigParser` as `SafeConfigParser` and monkey-patching so
that the class has the expected interface.

This prevents data loss when users configure the search cache Maildir to be a
real Maildir containing their real mail data, since the search cache Maildir
is expected to contain only symlinks to the real mail data.

Rename the function and adjust the documentation comment.

This should be be slightly faster since it avoids forking a shell
and is less code in and less dependencies for the script.
Since String::ShellQuote isn't used elsewhere, drop mention of it.
|
|
Spaces need to be stripped when querying the Message-Id,
because notmuch stores them in Xapian with spaces stripped.
All double-quote characters need to be doubled to escape them,
otherwise they will be added as extra query terms outside the id.

Instead of skipping indexing all attachments, we check of a (user
configured) mime type that is indexable as text.

We pre-parse into a list of compiled regular expressions to avoid
calling regexc on the hot (indexing) path. As explained in the code
comment, this cannot be done lazily with reasonable error reporting,
at least not without touching a lot of the code in index.cc.

This replaces two instances of Xapian::Query::MatchAll with the
equivalent but thread-safe alternative Xapian::Query(std::string()).
Xapian::Query::MatchAll maintains an internal pointer to a refcounted
Xapian::Internal::QueryTerm.
None of this is thread-safe but that wouldn't be an issue if
Xapian::Query::MatchAll wasn't static. Because it's static, the
refcounting goes awry when Notmuch is called from multiple threads.
This is actually documented by Xapian:
https://github.com/xapian/xapian/blob/4715de3a9fcee741587439dc3cc1d2ff01ffeaf2/xapian-core/include/xapian/query.h#L65
While static, Xapian::Query::MatchNothing is safe because it doesn't
maintain an internal object and as such, doesn't use references.
Two best-effort tests making use of TSan were added to showcase the
issue (I couldn't figure out a way to deterministically reproduce it
without making an unmaintainable mess).
First, when two databases are created in parallel, a query that uses
Xapian::Query::MatchAll is made (lib/query.cc), resulting in the
following backtrace on a segfault:
#0 0x00007ffff76822af in Xapian::Query::get_terms_begin (this=0x7fffe80137f0) at api/query.cc:141

Second, some queries would make use of Xapian::Query::MatchAll
(lib/regexp-fields.cc), resulting in the following backtrace on a
segfault:

Printing Xapian::Query::MatchAll->internal.px->_refs in these
circumstances can help quickly identifying this scenario.
This is motivated by some test frameworks (like Rust's Cargo) that
runs unit tests in parallel and would easily encounter this issue,
unless client code gates every call to Notmuch behind a lock.
This is what can be expected from the tests when they fail:

It wasn't covered, though it shares most of its implementation with
notmuch_message_remove_all_properties.
|
|
_notmuch_message_remove_all_properties wasn't syncing the message back
to the database but was still invalidating the metadata, giving the
impression the properties had actually been removed.
Also move the metadata invalidation to _notmuch_message_remove_terms
to be closer to what's done in _notmuch_message_modify_property and
_notmuch_message_remove_term.
|
|
Close and re-open the database to show that the removal is not
committed to the database.
|
|
notmuch_message_remove_all_properties should have removed the
testkey1 = testvalue1
property but hasn't. Delay the execution of the corresponding test
to avoid updating a few tests that actually relied on the broken
behavior.
