Added die() function to test-lib.sh with the following first use of it:
If notmuch new fails during email corpus addition the database is
most probably inexistent or broken and the added corpus would be
unusable while running single tests, giving misleading failures
("only" full 'make test' cleans out old corpus).
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
Most of the infrastructure here is general, only the validation/dispatch
is hardcoded to a particular prefix.
A notable change in behaviour is that notmuch-config now opens the
database e.g. on every call to list, which fails with an error message
if the database doesn't exit yet.
Since xapian provides the ability to restrict the iterator to a given
prefix, we expose this ability to the user. Otherwise we mimic the other
iterator interfances in notmuch (e.g. tags.c).
This is a thin wrapper around the Xapian metadata API. The job of this
layer is to keep the config key value pairs from colliding with other
metadata by transparently prefixing the keys, along with the usual glue
to provide a C interface.
The split of _get_config into two functions is to allow returning of the
return value with different memory ownership semantics.
The Ruby bindings were missing a way to get all the tags of the
database. Now you should be able to access this with the public
instance method `all_tags` of your database object.
Example of use:
notmuchdb = Notmuch::Database.new path, { :create => false,
:mode => Notmuch::MODE_READ_ONLY }
my_tags = notmuchdb.all_tags
my_tags.each { |tag|
print tag
}
my_tags.destroy!
Amended by db: improve error reporting, add test
Files in test directories had only copyright of a single individual,
of which code was adapted here as a base of the test system.
Since then many Notmuch Developers have contributed to the test
system, which is now acknowledged with a constant string in some
of the test files.
The README file in test directory instructed new files contain a
copyright notice, but that has never been done (and it is also not
needed). To simplify things a bit (and lessen confusion) this
instruction is now removed.
As a side enchangement, all of the 3 entries in the whole source
tree cd'ing to `dirname` of "$0" now uses syntax cd "$(dirname "$0")".
This makes these particular lines work when current working directory
is e.g. /c/Program Files/notmuch/test/.
(Probably it would fail elsewhere, though.)
In case of notmuch reply and notmuch show --part=N it is required that
search terms match to one message. If match count was != 1, error
message "Error: search term did not match precisely one message"
was too vague to explain what happened.
By appending (matched <num> messages) to the error message it
makes the problem more understandable (e.g when <num> is '0'
user reckons the query had a typo in it).
To fully complete the ghost-on-removal-when-shared-thread-exists
proposal, we need to clear all ghost messages when the last active
message is removed from a thread.
Amended by db: Remove the last test of T530, as it no longer makes sense
if we are garbage collecting ghost messages.
implement ghost-on-removal, the solution to T590-thread-breakage.sh
that just adds a ghost message after removing each message.
It leaks information about whether we've ever seen a given message id,
but it's a fairly simple implementation.
Note that _resolve_message_id_to_thread_id already introduces new
message_ids to the database, so i think just searching for a given
message ID may introduce the same metadata leakage.
This test (T590-thread-breakage.sh) has known-broken subtests.
If you have a two-message thread where message "B" is in-reply-to "A",
notmuch rightly sees this as a single thread.
But if you:
* remove "A" from the message store
* run "notmuch new"
* add "A" back into the message store
* re-run "notmuch new"
Then notmuch sees the messages as distinct threads.
This happens because if you insert "B" initially (before anything is
known about "A"), then a "ghost message" gets added to the database in
reference to "A" that is in the same thread, which "A" takes over when
it appears.
But if "A" is subsequently removed, no ghost message is retained, so
when "A" appears, it is treated as a new thread.
I see a few options to fix this:
ghost-on-removal
----------------
We could unilaterally add a ghost upon message removal. This has a
few disadvantages: the message index would leak information about what
messages the user has ever been exposed to, and we also create a
perpetually-growing dataset -- the ghosts can never be removed.
ghost-on-removal-when-shared-thread-exists
------------------------------------------
We could add a ghost upon message removal iff there are other
non-ghost messages with the same thread ID.
We'd also need to remove all ghost messages that share a thread when
the last non-ghost message in that thread is removed.
This still has a bit of information leakage, though: the message index
would reveal that i've seen a newer message in a thread, even if i had
deleted it from my message store
track-dependencies
------------------
rather than a simple "ghost-message" we could store all the (A,B)
message-reference pairs internally, showing which messages A reference
which other messages B.
Then removal of message X would require deleting all message-reference
pairs (X,B), and only deleting a ghost message if no (A,X) reference
pair exists.
This requires modifying the database by adding a new and fairly weird
table that would need to be indexed by both columns. I don't know
whether xapian has nice ways to do that.
scan-dependencies
-----------------
Without modifying the database, we could do something less efficient.
Upon removal of message X, we could scan the headers of all non-ghost
messages that share a thread with X. If any of those messages refers
to X, we would add a ghost message. If none of them do, then we would
just drop X entirely from the table.
---------------------
One risk of attempted fixes to this problem is that we could fail to
remove the search term indexes entirely. This test contains
additional subtests to guard against that.
This test also ensures that the right number of ghost messages exist
in each situation; this will help us ensure we don't accumulate ghosts
indefinitely or leak too much information about what messages we've
seen or not seen, while still making it easy to reassemble threads
when messages come in out-of-order.
The code to skip multiple slashes in _notmuch_database_split_path()
skips back one character too much. This is compensated by a +1 in the
length parameter to the strndup() call. Mostly this works fine, but if
the path is to a file under a top level directory with one character
long name, the directory part is mistaken to be part of the file name
(slash == path in code). The returned directory name will be the empty
string and the basename will be the full path, breaking the indexing
logic in notmuch new.
Fix the multiple slash skipping to keep the slash variable pointing at
the last slash, and adjust strndup() accordingly.
The bug was introduced in

Author: Carl Worth <cworth@cworth.org>
Date: Sat Dec 19 13:20:26 2009 -0800
database: Store the parent ID for each directory document.
just a little over two months after the initial commit in the Notmuch
code history, making this the longest living bug in Notmuch to date.
In several places in the test suite we intentionally corrupt the Xapian
database in order to test error handling. This corruption is specific to
the on-disk organization of the database, and that changed with the
glass backend. We use the previously computed default backend to make
the tests adapt to changing names.
This is mainly for the test suite. We already expect the tests to be
run in the same environment as configure was run, at least to get the
name of the python interpreter. So we are not really imposing a new
restriction.
This should potentially be updated to have an equivalent optimization
for the glass backend, but it in my unscientific tests, the glass backend
without the optimization is faster then the chert backend with.
When no decryption or signature examination is
happening (i.e. `notmuch-crypto-process-mime' is `nil') insert buttons
that indicate this, rather than remaining silent.
in d27d90875d (2016-02-20) notmuch-mua-reply-insert-header-p-function
was set to notmuch-show-reply-insert-header-p-never as its default was
changed to something else. Now that default is set back to *-never so
this change done in d27d90875d is not needed anymore.
We only need a long string, not a single long term to trigger batch
mode. The giant term triggers a bug/incompatibility in Xapian 1.3.4
that throws an exception because it is longer than the Xapian term size
limit.
Move the brief help text at the bottom of the hello screen to the
notmuch-hello-mode help, and promote '?' as the universal help key
across Notmuch. This unclutters the hello screen, and allows for a
more verbose description in the mode help. Hopefully, this change is
useful for both experienced and new users alike.
While at it, improve the links to Notmuch and hello screen
customization.
A while ago test script names were changed to format
Tddd-basename.sh. Update README to reflect that.
While at it, included some small requirements updates.
Add a customizable function specifying which parts get a header when
replying, and give some sensible possiblities. These are,
1) all parts except multipart/*. (Subparts of a multipart part do
receive a header button.)
2) only included text/* parts.
3) Exactly as in the show buffer.
4) None at all. This means the reply contains a mish-mash of all the
original message's parts.
In the test suite we set the choice to option 4 to match the
previous behaviour.
Use the message display code to generate message text to cite in
replies.
For now we set insert-headers-p function to
notmuch-show-reply-insert-header-p-never so that, as before, we don't
insert part buttons.
With that choice of insert-headers-p function there is only one
failing test: this test has a text part (an email message) listed as
application/octet-stream. Notmuch show displays this part, but the
reply code omitted it as it had type application/octet-stream. The new
code correctly includes it. Thus update the expected output to match.
notmuch-show --verify will now also process S/MIME multiparts if
encountered. Requires gmime-2.6 and gpgsm.
Based on work by Jameson Graef Rollins <jrollins@finestructure.net>.
The test is pretty much cut and paste from the PGP/MIME version, with
obvious updates taken from notmuch output. This also requires setting
up gpgsm infrastucture.
Test the ability of notmuch-mua-mail to send S/MIME signed (and
encrypted) messages; this really relies on existing functionality in
message-mode.
The generated keys and messages will later be useful for testing the
notmuch CLI.
ALTERNATE_EDITOR causes emacsclient to run an alternate editor if the
emacs server is not ready. This can collide with intended
functionality in test-lib.sh.
If the ALTERNATE_EDITOR is set but empty, emacsclient runs emacs
daemon and tries to connect to it. When this happens the emacs run by
test-lib.sh fails to start the server and the subsequent attempts to
use the server fail because the daemon started by emacsclient does not
know about notmuch-test-progn. This leads to test suite failure due to
time out on any emacs test.
When notmuch sources are at a symlinked path, some tests fail because
one part of the test uses physical path and another uses logical
path (with symlinks). For example the following test output is
produced when the test is started from /home/src/symlink-to-notmuch,
which is a symlink to /home/src/notmuch.

Of course I can't duplicate the mentioned problem, it probably depends
on specific message data.
Per RFC 2183, the values for Content-Disposition values are not
case-sensitive. While at it, use the gmime function for getting at the
disposition string instead of referencing the field directly.
This fixes "attachment" tagging and filename term generation for
attachments while indexing.
There was a problem with the directory documents being left behind when
the filesystem directory was removed. This was worked around in [1].
However, that ignored the fact that the directory documents are also
still listed by notmuch_directory_get_child_directories() leading to
confusing results when running notmuch new. The directory documents are
found and queued for removal over and over again.
Fix the problem for real by removing the directory documents. This fixes
the tests flagged as broken in [2].
The (non-deterministic) hack test from [3] also still passes with this
change.

breakage with (lack of) directory deletion.

First a simple smoke test first, next generate messages with multiple
email address variants and check the behaviour of deduplication
schemes with these.
It doesn't seem likely we can support simple date:<expr> expanding to
date:<expr>..<expr> any time soon. (This can be done with a future
version of Xapian, or with a custom query query parser.) In the mean
time, provide shorthand date:<expr>..! to mean the same. This is
useful, as the expansion takes place before interpetation, and we can
use, for example, date:yesterday..! to match from beginning of
yesterday to end of yesterday.
Idea from Mark Walters <markwalters1009@gmail.com>.
It isn't completely clear what we want to do here, but
1) We currently don't fail if we skip a whole test file (mainly because
we neglect to count those skipped tests properly). This change at least
makes the two kinds of skipping consistent.
2) Automated build environments may have good reasons for building with
a minimal set of prereqs, and we don't want to discourage running our
test suite by breaking builds.
Check argc mainly to fix unused parameter warning:
test/symbol-test.cc:7:14: warning: unused parameter ‘argc’ [-Wunused-parameter]
int main(int argc, char** argv) {
^
This makes more sense than telling the compiler it's unused on
purpose.
This brings back status information that may have been hidden by the
great library logging conversion.
Note the change of the internal API / return-value for count_files. The
other count calls to the lib will also get error handling when that API
is updated in the lib.
The function notmuch_exit_if_unmatched_db_uuid is split from
notmuch_process_shared_options because it needs an open notmuch
database.
There are two exceptional cases in uuid handling.
1) notmuch config and notmuch setup don't currently open the database,
so it doesn't make sense to check the UUID.
2) notmuch compact opens the database inside the library, so we either
need to open the database just to check uuid, or change the API.
In the short term we need a way to get lastmod information e.g. for
the test suite. In the long term we probably want to add lastmod
information to at least the structured output for several other
clients (e.g. show, search).
This exposes the committed database revision to library users along
with a UUID that can be used to detect when revision numbers are no
longer comparable (e.g., because the database has been replaced).
The files (test) scripts source (with builtin command `.`) provides
information which the scripts depend, and without the `source` to
succeed allowing script to continue may lead to dangerous situations
(e.g. rm -rf "${undefined_variable}"/*).
At the end of all source (.) lines construct ' || exit 1' was added;
In our case the script script will exit if it cannot find (or read) the
file to be sourced. Additionally script would also exits if the last
command of the sourced file exited nonzero.
Previously we globally modified these variables, which tended to cause
problems for people using message-mode, but not notmuch-mua-mail, to
send mail.
User visible changes:
- Calling notmuch-fcc-header-setup is no longer optional. OTOH, it
seems to do the right thing if notmuch-fcc-dirs is set to nil.
- The Fcc header is visible during message composition
- The name in the mode line is changed, and no longer matches exactly
the menu label.
- Previously notmuch-mua-send-and-exit was never called. Either we
misunderstood define-mail-user-agent, or it had a bug. So there was
no difference if the user called message-send-and-exit directly. Now
there will be.
- User bindings to C-c C-c and C-c C-s in message-mode-map are
overridden. The user can override them in notmuch-message-mode-map,
but then they're on their own for Fcc handling.
I marked the tests where I really couldn't understand the output as
broken. It could also be that I don't understand how directory removal
is supposed to work.
Try to narrow down what part of the code adds files and directories to
the queue(s) to be deleted.
Update one test. The output is slightly confusing, but I believe it is
correct, resulting from a directory being discovered but containing only ignored files.
The configure script chooses "python" if both python and python{2,3}
exist exists, so this could change the version of python used to run
the test suite.
The checking for ${NOTMUCH_PYTHON} in the test suite is arguably
over-engineering, since the configure step will fail if it can't find
it.
There are many places in the notmuch code where the path is assumed to be absolute. If someone (TM) wants a project, one could remove these assumptions. In the mean time, prevent users from shooting themselves in the foot.
Update test suite mark tests for this error as no longer broken, and
also convert some tests that used relative paths for nonexistent
directories.
The difference with FILE_ERROR is that this is for things that are
wrong with the path before looking at the disk.
Add some 3 tests; two broken as a reminder to actually use this new
code.
In the case the these tests fail, they generate a bunch of output;
this output is not very interesting because it is just the successful
output of a man page. It does however make it hard to see what tests are actually failing, even with NOTMUCH_TEST_QUIET
In particular this fixes a recently encountered bug where the
"--config" argument to "notmuch setup" is silently ignored, which the
unpleasant consequence of overwriting the users config file.
Quoting Debian bug 787341
It failed to build on arm64: the last ten tests in T070-insert
failed.
What's happening here is that GDB is segfaulting in response to
the
"file" command. GDB on arm64 can be a bit buggy.
However, the "file" command is redundant here as GDB has already
got
the file from the --args on the command line.
Apparently some systems actually have a directory called /nonexist[ae]nt.
It's hard to fathom a good reason for that, but oh well. As long as we
don't create such a directory inside the notmuch source tree, the new
version should be more robust.
When creating $THREADS data it may end of not having 'None' at all
or the numbers in line output yields a loop.
To avoid loop the value in current array index is set to 'None'
so that if the same item is reached again the loop will end.
Also empty string as next array index will end the loop.
This is not supposed to change any functionality from an end user
point of view. Note that it will eliminate some output to stderr. The
query debugging output is left as is; it doesn't really fit with the
current primitive logging model. The remaining "bad" fprintf will need
an internal API change.
The compatibility wrapper ensures that clients calling
notmuch_database_open will receive consistent output for now.
The changes to notmuch-{new,search} and test/symbol-test are just to
make the test suite pass.
The use of IGNORE_RESULT is justified by two things. 1) I don't know
what else to do. 2) asprintf guarantees the output string is NULL if
an error occurs, so at least we are not passing garbage back.
This is to limit the copy-pasta involved in running C tests. I decided
to keep things simple and not try to provide an actual C skeleton.
The setting of LD_LIBRARY_PATH is to force using the built libnotmuch
rather than any potential system one.
This is arguably testing the same thing twice, but in the brave new
future where we don't use printf anymore, each subcommand will be
responsible for handling the output on it's own.
Previously we set up a way for the top level notmuch command to choose
which gpg binary was invoked by libgmime. In this commit we add the
(mostly boilerplate) code to allow the notmuch-config command to read
and write this path, and use it in the appropriate struct.
Update tests for new default variable
If seconds are not specified in the string to be parsed, they're not
set according to the reference time (in the no rounding case) nor
rounded properly (in the rounding up cases). Fix this.
The bug caused searches such as date:10:30..10:30 to match messages
with date exactly 10:30:00 only, and not in range 10:30:00..10:30:59
(inclusive) as documented.
Note that date searches referring "noon" or "5pm" will still be
interpreted as exact to the second.
Extract and add some more tests relating to rounding seconds into a
separate subtest, and flag it as broken. If seconds are not specified,
the time is not set or rounded according to the interface defined in
parse-time-string/parse-time-string.h. Instead, seconds are always set
to 00 in reality, which is broken.
Set the reference time to 12:13:14 instead of 11:11:00 to ensure hours
and minutes are not mixed up, and seconds are really set instead of
defaulted to 00.
This adds the indexing support for the "mimetype:" term and removes
the broken test flag. The indexing is probablistic in Xapian terms,
which gives a better experience to end users. Standard content-types
of the form "foo/bar" are automatically interpreted as phrases in
Xapian due to the embedded slash.
Assume, separate messages with application/pdf and application/x-pdf
are indexed, then:
- mimetype:application/x-pdf will find only the application/x-pdf
- mimetype:application/pdf will find only the application/pdf
- mimetype:pdf will find both of the messages
Adds three failing unit tests for searching of mime-types.
An attempt was made at adding a negative test (i.e. searching for a
non-existent mime-type and ensuring it didn't return a message), but
that test would always pass making it pointless.
When something in tests fails one possibility to test is to run
the test script as `bash -x TXXX-testname.sh`. As stderr (fd 2) was
redirected to separate file during test execution also this set -x
(xtrace) output would also go there.
test-lib.sh saves the stderr to fd 7 from where it can be restored,
and bash has BASH_XTRACEFD variable, which is now given the same value
7, making bash to output all xtrade information (consistently) there.
This lib file used to save fd's 1 & 2 to 6 & 7 (respectively) in
test_begin_subtest(), but as those needs to be set *before* XTRACEFD
variable is set those are now saved at the beginning of the lib (once).
This is safe and simple thing to do.
To make xtrace output more verbose PS4 variable was set to contain the
source file, line number and if execution is in function, that function
name. Setting this variable has no effect when not xtracing.
As it is known that fd 6 is redirected stdout, printing status can now
use that fd, instead of saving stdout to fd 5 and use it.
At the moment, the test-lib fills in any missing headers. This makes
it impossible to test our handling of empty subjects. This will
allow us to use a special dummy subject -- `@FORCE_EMPTY` -- to force
the subject to remain empty.
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.

We test for whether a quoted empty email address
"" <address@example.com>
will show up as the address, instead of the empty string. This is
marked as known-broken, since the current behavior is to use the empty
string.
This is a new test file, since handling of unusual email addresses
doesn't seem to fit well in any of our existing tests.

The code here is an extended version of a patch from Jani Nikula.
python3 doesn't allow dictionaries to be initialized with non-string
keywords. This presents problems on systems in which "python" means
"python3". We instead initalize the dictionary using the dict
comprehension and then update it with the values from the tree. This
will work with both python2 and python3.
Apparently the test binaries are built with minimal LDFLAGS, only
adding dependency specific LDFLAGS as needed. However because some of
the test binaries incorporate notmuch object files, it is necessary to
use the same link flags as notmuch. For example user provided
CFLAGS/CXXFLAGS/LDFLAGS with -fsanitize=undefined fails to build the
test binaries if the flags differ.
In emacs 24.4 the messages buffer starts being read-only, which kills
these tests. This seems to be the point of the variable
inihibit-read-only, which has existed at least since emacs 21.
After yet another variation in objdump output caused this test to fail

This version uses nm -P. nm -P should be portable, and fixed format.
It purposely doesn't use the -D argument, since that is non-POSIX and

thing to do there is to move some more configuration information into

notmuch would give the rather un-friendly and un-actionable message
Error reading configuration file .notmuch-config: No such file or directory
Since this condition is expected for new users, this patch adds
specific handling for the file-not-found case to give a message that
is friendly and actionable.
The version number has always been pretty meaningless to the user and
it's about to become even more meaningless with the introduction of
"features". Hopefully, the database will remain on version 3 for some
time to come; however, the introduction of new features over time in
version 3 will necessitate upgrades within version 3. It would be
confusing if we always tell the user they've been "upgraded to version
3". If the user wants to know what's new, they should read the news.
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 the build system was generating automatic header
dependencies for test sources, but only smtp-dummy was in SRCS, so
only its dependencies were being included. Add all of the test
sources to SRCS so that the root Makefile.local includes their
dependencies.
This should help new users off to a better start with the addition of
more sensible saved searches and default shortcut keys. Most existing
users have probably customized this variable and won't be affected.
Dump currently only takes the read lock. Xapian can cope with some
changes while maintaining a read snapshot but with more changes it
fails. Currently notmuch just gives a xapian error.
To avoid this we take the write lock when dumping. This prevents other
notmuch processes from modifying the xapian database preventing this
error.
Discussion with Olly on irc indicates that this is currently the best
solution: in xapian trunk there may be better possibilities using
snapshots but they need to make it to a release and propogate out to
users before we can switch approach.
Finally, this breaks one use case: pipelines of the form
notmuch dump | ... | notmuch restore
According to Olly this is already very fragile: it will only work on
small databases. One of the tests relies on this behaviour so fix that
to store the dump rather than use a pipe.
These tests deliver all possible (single-root) four-message threads in
all possible orders and check that notmuch successfully links them
into threads. These tests supersede and replace the previous and much
less thorough "T260-thread-order" tests.
There are two variants of the test: one delivers messages that
reference only their immediate parent and the other delivers messages
that reference all of their parents. The latter test is currently
known-broken.
The unread/read changes will use the post-command-hook. test_emacs
does not call the post-command-hook. This adds a notmuch-test-progn
which takes a list of commands as argument and executes them in turn
but runs the post-command-hook after each one.
The caller can batch operations (ie to stop post-command-hook from
being interleaved) by wrapping the batch of operations inside a progn.
We also explicitly run the post-command-hook before getting the output
from a test; this makes sense as this will be a place the user would
be seeing the information.
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.
This adds two known-broken tests and one working test related to the
term positions assigned to terms from different headers or MIME parts.
The first test fails because we don't create a termpos gap between
different headers. The second test fails because we don't adjust
termpos at all when indexing multiple parts.
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.
Two of these are currently known-broken. We index the name and
address parts in two separate calls to _notmuch_message_gen_terms.
Currently this has the effect of placing the term positions of the
prefixed terms from the second call right after those of the first
call, but screws up the term positions of the non-prefixed terms.
Two of the search tests for "from" and "to" queries were clearly
trying to search for prefixed phrases, but forgot to shell quote the
phrases. Fix this by quoting them correctly.
This is effectively a revert of

Author: Jani Nikula <jani@nikula.org>

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.
At least in emacs24, this removes the "site-lisp" directories from the
load path in addition to enforcing --no-site-lisp --no-init-file.
This works around a slightly mysterious bug on Debian that causes
test-lib.el not to load when there is cl-lib.el(c) in some site-lisp
directory. It should be harmless in general since we really don't
want to load any files from addon packages to emacs.
It turns out to be inconvenient to delete the downloaded datafiles with
distclean, so I propose a new target which does that instead.
The closest conventional target is 'maintainer-clean'; the difference
here is that having the original source tarball is not enough to
reconstruct these files.
The linking to talloc is hard-coded in the testing Makefile. This patch
causes the linking to talloc to be done according to how TALLOC_LDFLAGS
was configured.

- The old test was quite impossible to debug; the new one shows the difference
between the two directories, if any.
- "repository" doesn't make sense for out of tree builds. Or tarball
builds, for that matter.
All we do here is calculate the backup filename, and call the existing
dump routine.
Also take the opportunity to add a message about being safe to
interrupt.
The main goal is to support gzipped output for future internal
calls (e.g. from notmuch-new) to notmuch_database_dump.
The additional dependency is not very heavy since xapian already pulls
in zlib.
We want the dump to be "atomic", in the sense that after running the
dump file is either present and complete, or not present. This avoids
certain classes of mishaps involving overwriting a good backup with a
bad or partial one.
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.
Previously, the term escaper used a blacklist of characters that
needed escaping. This blacklist turned out to be somewhat incomplete;
for example, it did not contain non-whitespace ASCII control
characters or Unicode "fancy quotes", both of which do require the
term to be escaped.
Switch to a whitelist of characters that are definitely safe to leave
unquoted. This fixes the broken test introduced by the previous
patch.
The current term escaper gets most of these right, but fails to escape
things containing Unicode "fancy quotes" or things containing
non-whitespace control characters.
I still have one machine with old enough Xapian to not have compaction
support. Make the tests check for unsupported compact operation when
compact is not available.
This allows (and requires) the original-tags to be passed along with
the current-tags to be passed to notmuch-tag-format-tags. This allows
the tag formatting to show added and deleted tags.By default a removed
tag is displayed with strike-through in red (if strike-through is not
available, eg on a terminal, inverse video is used instead) and an
added tag is displayed underlined in green.
If the caller does not wish to use the new feature it can pass
current-tags for both arguments and, at this point, we do exactly that
in the three callers of this function.
Note, we cannot tidily allow original-tags to be optional because we would
need to distinguish nil meaning "we are not specifying original-tags"
from nil meaning there were no original-tags (an empty list).
We use this in subsequent patches to make it clear when a message was
unread when you first loaded a show buffer (previously the unread tag
could be removed before a user realised that it had been unread).
The code adds into the existing tag formatting code. The user can
specify exactly how a tag should be displayed normally, when deleted,
or when added.
Since the formatting code matches regexps a user can match all deleted
tags with a ".*" in notmuch-tag-deleted-formats. For example setting
notmuch-tag-deleted-formats to '((".*" nil)) tells notmuch not to show
deleted tags at all.
All the variables are customizable; however, more complicated cases
like changing the face depending on the type of display will require
custom lisp.
Currently this overrides notmuch-tag-deleted-formats for the tests
setting it to '((".*" nil)) so that they get removed from the display
and, thus, all tests still pass.
It turns out there was a reason the old man pages were stored in a man
compatible hierarchy, namely so that we could run man on them before
installing.
Hardcode doc build location into test suite. This isn't ideal, but
let's unbreak the test suite for now.
The checksum file is used by the test infrastructure to verify the downloaded
test database is the one we had in mind. Note that this test is
rather strict, and the the checksum file needs to be recommitted when
the database is regenerated.
add a pattern .gitignore to ignore the actual databases
Test the upgrade from probabilistic to boolean folder: terms, and
addition of path: terms.
The test depends on the pre-built test corpus and database tarball and
checksum file being in place. If it's not, the test is skipped. The
mechanism to fetch the test database will be added later.
At the time of writing, a working test database and checksum file is
available at
http://notmuchmail.org/releases/test-databases/
It has been noted that some non-GNU environments make lack
sha256sum. We leave this portability issue for a followup patch.
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.
We will need this for improved folder search tests, but having some
folders should exercise our code paths better anyway.
Modify the relevant test accordingly to make it pass.
This reorganization triggers a bug in the test suite, namely that it
expects the output of --output=files to be in a certain order. So we
add the fix for that into the same commit.
This mainly involves sorting, although the case --duplicate=$n
requires more subtlety.
Sanitize tabs and newlines to spaces rather than question marks in
--output=summary --format=text output.
This will also hide any difference in unfolding a header that has been
folded with a tab. Our own header parser replaces tabs with spaces,
while gmime would retain the tab.
The printf builtin "%(fmt)T" specifier (which allows time values
to use strftime-like formatting) is introduced in bash 4.2.
Trying to execute this in pre-4.2 bash will fail -- and if this
happens execute the fallback piece of perl code to do the same thing.
The test names assigned to NOTMUCH_SKIP_TESTS variable can now be given
with or without the Tddd- prefix for tester convenience:
The test name without Tddd -prefix stays constant even when test filenames
are renumbered.
The test name with Tddd -prefix is printed out when tests run.
According the semantics of make, the expansion of $(dir) in recipes
uses dynamic scope, i.e. the value at the time the recipe is run. This
means if test/Makefile.local is not the last sub-makefile included,
all heck breaks loose.
Previously, we stripped the "Tnnn-" part from the test name when
printing its description at the beginning of each test. However, this
makes it difficult to find the source script for a test (e.g., when a
test fails). Put this prefix back.
Searching by Message-Id no longer works via the old mail-archive.com
API, though I have contacted them in hopes that they restore it to
prevent dead links. Anyway, the new API is cleaner.

Script `notmuch-test` expects the results file have T\d\d\d- part
intact so the results files (and some test output files) are now
name as such.
Without this change `notmuch-test` will exit in case the test
script it was executing exited with nonzero value.
The T\d\d\d- part is dropped in new variable $this_test_bare which is
used in progress informational messages and when loading .el files in
emacs tests (whenever $this_test_bare.el exists).
If there is a syntax error in the emacs test library, it causes other
tests to hang or crash without a useful error message.
This test could be eliminated if the error reporting for emacs tests
was somehow improved.
All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
When naming test scripts in format 'T\d\d\d-name.sh' the list of
tests to run are created dynamically. This makes test
'Ensure that all available tests will be run by notmuch-test'
in test/basic obsolete.
Previously the tags on each line in tree view were separarted by ", "
not just " ". This is different from show and search views.
This patch removes this comma. This is a large patch as essentially
every line of each of the expected outputs in the tree tests needs
updating.
Apart from aesthetic reasons this simplifies the switch to
notmuch-tag-format-tags in the next patch.
In some environments (at least Hurd), process-attributes is
unimplimented and always returns nil. This ends up causing test
failures (see e.g. id:87a9ffofsc.fsf@zancas.localnet).
Historically and according to POSIX 1003.1-2001, a signal of 0 can be
used to check the validity of a pid. This seems less heinous than
parsing the output of ps(1).
This fixes a non-deterministic failure in "Ignore files and
directories specified in new.ignore (multiple occurrences)". The test
assumed that all directories would be scanned, even though nothing
updated the mtime of ${MAIL_DIR}. It *usually* worked nevertheless
because the tests run quickly enough that the directory mtime is
usually the same as the current time, so notmuch new does not update
the mtime in the database (because more changes could occur in the
same second). However, when it occasionally did update the mtime in
the database, the notmuch new call in this test would (correctly) skip
"pass 2" of scanning ${MAIL_DIR}, causing it to skip the following
expected lines:
(D) add_files_recursive, pass 2: explicitly ignoring ${MAIL_DIR}/.git
(D) add_files_recursive, pass 2: explicitly ignoring ${MAIL_DIR}/.ignored_hidden_file
(D) add_files_recursive, pass 2: explicitly ignoring ${MAIL_DIR}/ignored_file
This patch fixes this problem by touching ${MAIL_DIR} to ensure it
gets scanned and by rearranging the test to ensure the directories are
touched immediately before the main notmuch new call in the test.
There is an obscure bug in notmuch-hello that very occasionally causes
emacs_deliver_message to fail. Since it it doesn't serve any actual
purpose in the function we delete it, and leave tracking down the the
bug for another day.
Most of the tests previously using emacs_deliver_message do not use
the actual transmitted message, so we replace it with a simpler (and
presumably more reliable function) that only saves (and indexes) an
fcc copy of the message.
When NOTMUCH_TEST_QUIET environment variable is set to non-null value
messages when new test script starts and when test PASSes are disabled.
This eases picking the cases when tests FAIL (as those are still printed).
In preparation for quiet mode print empty line before writing the
test description. This is done now in function designed for it --
it will also be called when test fails.
test-lib.sh sometimes did equivalent of `basename "$0" .sh`, sometimes
skipping the basename part and sometimes .sh part. This worked as
we never had path components in $0 (more than ./) nor .sh ending.
Now the equivalent of `basename "$0" .sh` is done once and used
everywhere. In the future we may have .sh suffix in test names
-- removing those is a good idea.
The choice of decreasing timestamps is a hack which reduces the number
of existing tests which fail. This can be changed to increasing
if/when somebody wants update another 47 tests.
add a new function notmuch_date_sanitize for rfc822-ish things. Add
date sanitization to notmuch_show_sanitize_all and use it more places.
This is all in aid of a transition to unique timestamps on messages.
Eventually we want test messages to have distinct dates to avoid
reproducability problems. This sanitization will prevent some test
failures when that change is made.
Replace the use of a local function in maildir-sync with
notmuch_json_show_sanitize
This was causing test failures because version strings varied in
length between GNU/Linux and GNU/KFreeBSD. One can also imagine
different versions of gnupg causing the same failure.
When executed command line is written to *Notmuch errors* buffer,
shell-quote-argument will backslash-escape any char that is not in
"POSIX filename characters" (i.e. matching "[^-0-9a-zA-Z_./\n]").
Currently in two emacs tests shell has expanded $PWD as part of
emacs variable, which will later be fed to #'shell-quote-argument
and finally written to ERROR file. If $PWD contained non-POSIX
filename characters, data in ERROR file will not match $PWD when
later comparing in shell. Therefore, in these two particular cases
the escaped $PWD is replaced with YYY in ERROR file and expected
content is adjusted accordingly.
This fixes races in thread-local and global tagging in notmuch-search
(e.g., "+", "-", "a", "*", etc.). Previously, these would modify tags
of new messages that arrived after the search. Now they only operate
on the messages that were in the threads when the search was
performed. This prevents surprises like archiving messages that
arrived in a thread after the search results were shown.
This eliminates `notmuch-search-find-thread-id-region(-search)'
because these functions strongly encouraged racy usage.
This fixes the two broken tests added by the previous patch.
These tests check that both thread-local and global search tagging
operations are race-free. They are currently known-broken because
they aren't race-free.
These queries will match exactly the set of messages currently in the
thread, even if more messages later arrive. Two queries are provided:
one for matched messages and one for unmatched messages.
This can be used to fix race conditions with tagging threads from
search results. While tagging based on a thread: query can affect
messages that arrived after the search, tagging based on stable
queries affects only the messages the user was shown in the search UI.
Since we want clients to be able to depend on the presence of these
queries, this ushers in schema version 2.
(Unfortunately, it's difficult to first demonstrate this problem with
a known-broken test because modern Linux kernels have argument length
limits in the megabytes, which makes Emacs really slow!)
It was looking in completely the wrong place for the backup and the
(test) xapian database. Unfortunately test_begin_subtest hides the
relevant errors.
Currently notmuch-show looks at the prefix-arg directly via
current-prefix-arg. This changes it to use the interactive
specification.
One test (for elide-toggle functionality) set the prefix arg
directly. Update this test to set the new argument directly.
One test (reply to encrypted message in the crypto test) recently
started failing on some systems. The failure I saw were two extra
lines of the form
<87d2nbc5xg.fsf@host.i-did-not-set--mail-host-address--so-tickle-me>
The test pipes the output through
grep -v -e '^In-Reply-To:' -e '^References:'
which would normally these two ids but it does not, in this case,
because they are so long they get put on a separate line in the output.
To fix this we set mail-host-address for emacs deliver. example.com
seems a sensible address to use. This is short enough that we don't
get the line breaks above and the tests then all pass.

Some common broken RFC 2047 encodings that we currently let gmime
parse strictly. We could tell gmime to be forgiving in what it accepts
as RFC 2047 encoding, making these tests pass.
When 'xpg_echo' bash shell option is unset (usually the default)
echo builtin does not expand backslash-escape sequences by default
(i.e. '\n' is echoed as '\n' instead of newline). Not all bash
installations have this feature we depend on activated by default.
Note that the feature is bash (and GNU /bin/echo) specific. It is used
as it is convenient. If portability is needed (elsewhere) use printf(1)
(also often available as a shell builtin).
If any of the tests in our test system is not passing the execution
of the test suite completes with nonzero exit value.
It is better to rely on the exit value of the test system instead
of some arbitrary strings in test output (or use both).
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.

update insert tests for new maildir synchronization rules
As of id:1355952747-27350-4-git-send-email-sojkam1@fel.cvut.cz
we are more conservative about moving messages from ./new to ./cur.
This updates the insert tests to match
As mentioned by Jani Nikula in id:87vcccp4y3.fsf@nikula.org, some cases
of maildir synchronization are not covered by our tests. Let's add the
missing tests.
Some MUA's like mutt show the difference between "new" emails living in maildir
directory new/, and "old" emails living in maildir directory cur/. However
notmuch tag unconditionally moves selected messages from new/ to cur/, even if
no maildir synchronized tag is changed.
While maildir specification forbids messages with tags living in new/, there is
no need to move messages to cur/ when no maildir synchronized tag is changed.
Thus notmuch can remain transparent with respect to other MUA's.

RFC 2047 states that the encoding and charset in an encoded word are
case-insensitive, so force them to lower case in the reply test. This
fixes an issue caused by GMime versions (somewhere between 2.6.10 and
2.6.16), which changed the capitalization of the encoding.
Previously, reply's default text format used an odd mix of RFC 2045
MIME encoding for the reply template's body and some made-up RFC
2822-like UTF-8 format for the headers. The intent was to present the
headers to the user in a nice, un-encoded format, but this assumed
that whatever ultimately sent the email would RFC 2047-encode the
headers, while at the same time the body was already RFC 2045 encoded,
so it assumed that whatever sent the email would *not* re-encode the
body.
This can be fixed by either producing a fully decoded UTF-8 reply
template, or a fully encoded MIME-compliant RFC 2822 message. This
patch does the latter because it is
a) Well-defined by RFC 2822 and MIME (while any UTF-8 format would be
ad hoc).
b) Ready to be piped to sendmail. The point of the text format is to
be minimal, so a user should be able to pop up the template in
whatever editor they want, edit it, and push it to sendmail.
c) Consistent with frontend capabilities. If a frontend has the
smarts to RFC 2047 encode the headers before sending the mail, it
probably has the smarts to RFC 2047 decode them before presenting
the template to a user for editing.
Also, as far as I know, nothing automated consumes the reply text
format, so changing this should not cause serious problems. (And if
anything does still consume this format, it probably gets these
encoding issues wrong anyway.)
Previously, the References header code seemed to assume
notmuch_message_get_header would return NULL if the header was not
present, but it actually returns "". As a result of this, it was
inserting an unnecessary space when concatenating an empty or missing
original references header with the new reference.
This shows up in only two tests because the text reply format later
passes the whole reply template through g_mime_filter_headers, which
has the side effect of stripping out this extra space.
This switches `notmuch-mua-reply' and `notmuch-query-get-threads' to
the S-exp format. These were the last two uses of the JSON format in
the Emacs frontend.
While looked good on paper, its attempted use caused confusion, complexity,
and potential for information leak when passed through wrapper scripts.
For slimmer code and to lessen demand for maintenance/support the set of
commits which added top level --stderr= option is now reverted.
The find option syntax `-perm +111` is deprecated gnu find feature.
The replacement `( -perm -100 -o -perm -10 -o -perm 1 )` should also
work outside of the GNU domain.
In addition to being the Right Thing to do, this noticeably improves
the time taken to display the first page of search results, since it's
roughly an order of magnitude faster than the JSON parser.
Interestingly, it does *not* significantly improve the time to
completely fill a large search buffer because for large search
buffers, the cost of creating author invisibility overlays and
inserting text (which slows down with more overlays) dominates.
However, the time required to display the first page of results is
generally more important to the user experience.
Previously, search started the async notmuch process directly. Now,
it uses `notmuch-start-notmuch'. This simplifies the process sentinel
a bit and means that we no longer have to worry about errors
interleaved with the JSON output.
We also update the tests of Emacs error handling, since the error
output is now separated from the search results buffer.
We now check error handling more carefully in the last test in
test/emacs and we're about to add more error handling tests. (This
was also a strange place for this test, since it had nothing to do
with large search buffers.)
This unifies the part button actions and the underlying part action
functions into single interactive command that simply applies to the
part containing point using the just-added part p-list text property
instead of button properties. Since all part actions can be performed
by applying the appropriate mm function to an mm-handle, this patch
abstracts out the creation of mm handles, making the implementations
of the part commands trivial. This also eliminates our special
handling for part save in favor of using the appropriate mm function.
This necessarily modifies the way we handle the default part button
action, but in a way that does not change the meaning of the
notmuch-show-part-button-default-action defcustom.
Since these commands are no longer specific to buttons, this patch
eliminates the extra metadata stored with each button. This also
eliminates one rather special-purpose macro for a collection of
general purpose part handling utilities.
--stderr=FILE tests were added to test/help-test as it is the one
doing most global option testing. Also, it was simplest to test
this new option using `notmuch help` command.
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.
V2 of this patch, incorporating feedback from Jani and (indirectly)
Austin.
