We adopt a pythonic idiom here with an optional argument, rather than
exposing the user to the C indexopts object directly.
This now includes a simple test to ensure that the decrypt_policy
argument works as expected.
This test passes with older versions of Xapian as well, because
neither query returns any results.

The current behaviour is at best under-documented. The modified test in
T470-missing-headers.sh previously relied on printf doing the right
thing with NULL, which seems icky.
The use of talloc_strdup here is probably overkill, but it avoids
having to enforce that thread->authors is never mutated outside
_resolve_thread_authors_string.
If we're building against a version of Xapian that doesn't offer
retrying the lock, we should be honest and describe the tests as
broken, rather than marking them as missing a test prerequisite.
missing test prerequisites should be for specific components of the
test harness that are missing, not for the backend library notmuch
uses.
Named queries don't work without Xapian FieldProcessor. Rather than
silently skipping them, we should explictly mark them as broken when
building against an older version of Xapian.
Previously, the test suite had simply silently skipped the absolute
date test if we're using an archaic version of Xapian. For
correctness, we should instead mark the test as broken.
This also changes from string to numeric comparison when checking
NOMTUCH_HAVE_XAPIAN_FIELD_PROCESSOR for consistency with other tests.
The old name has a bit of a feeling of hungarian notation. Also many
generators in the core are named with the suffix "s" to indicate
iterables: dict.items, dict.keys for example.
This test will pass if either the notmuch show mitigation code is
working correctly, or upstream emacs mime handling code has it's own
fix for https://bugs.gnu.org/28350.
When i'm trying to understand a message signature, i care that i know
who it came from (the "validity" of the identity associated with the
key), *not* whether i'm willing to accept the keyholder's other
identity assertions (the "trust" associated with the certificate).
We've been reporting User ID information based on the "trust"
associated with the certificate, because GMime didn't clearly expose
the validity of the User IDs.
This change relies on fixes made in GMime 3.0.3 and later which
include https://github.com/jstedfast/gmime/pull/18.
Here's the configuration choice for people who want a cleartext index,
but don't want stashed session keys.
Interestingly, this "nostash" decryption policy is actually the same
policy that should be used by "notmuch show" and "notmuch reply",
since they never modify the index or database when they are invoked
with --decrypt.
We take advantage of this parallel to tune the behavior of those
programs so that we're not requesting session keys from GnuPG during
"show" and "reply" that we would then otherwise just throw away.
If you're going to store the cleartext index of an encrypted message,
in most situations you might just as well store the session key.
Doing this storage has efficiency and recoverability advantages.
Combined with a schedule of regular OpenPGP subkey rotation and
destruction, this can also offer security benefits, like "deletable
e-mail", which is the store-and-forward analog to "forward secrecy".
But wait, i hear you saying, i have a special need to store cleartext
indexes but it's really bad for me to store session keys! Maybe
(let's imagine) i get lots of e-mails with incriminating photos
attached, and i want to be able to search for them by the text in the
e-mail, but i don't want someone with access to the index to be
actually able to see the photos themselves.
Fret not, the next patch in this series will support your wacky
uncommon use case.
There are some situations where the user wants to get rid of the
cleartext index of a message. For example, if they're indexing
encrypted messages normally, but suddenly they run across a message
that they really don't want any trace of in their index.
In that case, the natural thing to do is:
notmuch reindex --decrypt=false id:whatever@example.biz
But of course, clearing the cleartext index without clearing the
stashed session key is just silly. So we do the expected thing and
also destroy any stashed session keys while we're destroying the index
of the cleartext.
Note that stashed session keys are stored in the xapian database, but
xapian does not currently allow safe deletion (see
https://trac.xapian.org/ticket/742).
As a workaround, after removing session keys and cleartext material
from the database, the user probably should do something like "notmuch
compact" to try to purge whatever recoverable data is left in the
xapian freelist. This problem really needs to be addressed within
xapian, though, if we want it fixed right.
The new "auto" decryption policy is not only good for "notmuch show"
and "notmuch reindex". It's also useful for indexing messages --
there's no good reason to not try to go ahead and index the cleartext
of a message that we have a stashed session key for.
This change updates the defaults and tunes the test suite to make sure
that they have taken effect.
When showing a message, if the user doesn't specify --decrypt= at all,
but a stashed session key is known to notmuch, notmuch should just go
ahead and try to decrypt the message with the session key (without
bothering the user for access to their asymmetric secret key).
The user can disable this at the command line with --decrypt=false if
they really don't want to look at the e-mail that they've asked
notmuch to show them.
and of course, "notmuch show --decrypt" still works for accessing the
user's secret keys if necessary.
If the user doesn't specify --decrypt= at all, but a stashed session
key is known to notmuch, when replying to an encrypted message,
notmuch should just go ahead and decrypt.
The user can disable this at the command line with --decrypt=false,
though it's not clear why they would ever want to do that.
This new automatic decryption policy should make it possible to
decrypt messages that we have stashed session keys for, without
incurring a call to the user's asymmetric keys.
Future patches in this series will introduce new policies; this merely
readies the way for them.
We also convert --try-decrypt to a keyword argument instead of a boolean.
the command-line interface for indexing (reindex, new, insert) used
--try-decrypt; and the configuration records used index.try_decrypt.
But by comparison with "show" and "reply", there doesn't seem to be
any reason for the "try" prefix.
This changeset adjusts the command-line interface and the
configuration interface.
For the moment, i've left indexopts_{set,get}_try_decrypt alone. The
subsequent changeset will address those.
If the version of GMime we're building against doesn't support session
key extraction or re-use, mark the tests that rely on session key
capabilities as known-broken.
This should resolve test suite failures on ubuntu trusty and debian
jessie and earlier, which have GMime 2.6.20 -- session key support was
introduced in GMime 2.6.21.
If you've got a notmuch dump that includes stashed session keys for
every decrypted message, and you've got your message archive, you
should be able to get back to the same index that you had before.
Here we add a simple test that give some flavor of how that works.
In 8e7fb88237 Jani replaced the use of $(pwd -P) to find the
TEST_DIRECTORY in order to better support out of tree
builds. Unfortunately the performance-tests need a different value for
the variable and were thus broken.
This commit splits out the setting of this variable for the two sets
of tests. Performance tests still don't work out of tree, because
the handling of the downloaded corpus needs to be updated.
backup_database() and restore_database() used to store the backups in
the test specific temporary directory, through the current working
directory being there. Commit 8e7fb88237 ("test: use source and
build paths in test-lib-common.sh") started using a test specific
backup directories under the build tree test directory. This was in
error. Switch back to the old location, but using paths to the
location instead of relying on current working directory.
Reported by Daniel Kahn Gillmor <dkg@fifthhorseman.net>.
Enable override of the index.try_decrypt setting on a per-run basis
when invoking "notmuch reindex". This allows the possibility of (for
example) an emacs keybinding that adds the cleartext of the currently
shown decrypted message to the index, making it searchable in the
future.
It also enables one-time indexing of all messages matching some query,
like so:
notmuch reindex tag:encrypted and\
not property:index.decryption=success and\
from:alice@example.org
We also update the documentation and tab completion, and add a few
more tests.
Enable override of the index.try_decrypt setting on a per-message
basis when invoking "notmuch insert".
We also update the documentation and tab completion, and add more tests.
Enable override of the index.try_decrypt setting during "notmuch new"
on a per-invocation basis.
We update the documentation and tab completion, and also add a test.
Subsequent patches may want to send GNU-style --long-arguments to
notmuch new in the test suite, in particular when invoking
emacs_fcc_message. This changeset makes that possible.
The primary motivation here is to fix TMP_DIRECTORY cleanup prior to
running each test when the current working directory is not the test
subdirectory. Tests with failures would leave their TMP_DIRECTORY
directory behind for debugging, and repeated out-of-tree test runs
would have old temp directories. (This lead to e.g. T310-emacs.sh
hanging because emacs would prompt for overwriting files.)
We remove the likely anyway defunct --root test option while at it,
just to be on the safe side when doing 'rm -rf' on the TMP_DIRECTORY.
Turns out round trip tests didn't really round trip anything. Broken
by yours truly in 971cdc72cd ("test: make it possible to have
multiple corpora"). Ooops.
C99 stdbool turned 18 this year. There really is no reason to use our
own, except in the library interface for backward
compatibility. Convert the cli and test binaries to stdbool.
Several changes at once, just to not have to change the same lines
several times over:
- Use designated initializers to initialize opt desc arrays.
- Only initialize the needed fields.
- Remove arg_id (short options) as unused.
- Replace opt_type and output_var with several type safe output
variables, where the output variable being non-NULL determines the
type. Introduce checks to ensure only one is set. The downside is
some waste of const space per argument; this could be saved by
retaining opt_type and using a union, but that's still pretty
verbose.
- Fix some variables due to the type safety. Mostly a good thing, but
leads to some enums being changed to ints. This is pedantically
correct, but somewhat annoying. We could also cast, but that defeats
the purpose a bit.
- Terminate the opt desc arrays using {}.
The output variable type safety and the ability to add new fields for
just some output types or arguments are the big wins. For example, if
we wanted to add a variable to set when the argument is present, we
could do so for just the arguments that need it.
Beauty is in the eye of the beholder, but I think this looks nice when
defining the arguments, and reduces some of the verbosity we have
there.
This imports a message with ISO-8859-2 encoded characters, then opens

Commit a7964c86d1 ("emacs: Sanitize authors and subjects in search

the same for reply subjects.
This fixes the long-standing annoying artefact of certain versions of
mailman using tab as folding whitespace, leading to tabs in reply
subjects.
This is a logical followup to "lib: index the content type of
signature parts", which will make it easier to record the message
structure of all messages.
It's useful (*) to be able to easily find messages with certain types
of signatures. Having the mimetype: prefix searches fail for some
content types is also genuinely surprising (*). Index the content type

While at it, switch to the gmime convenience constants for content and
signature part indexes.

Add known broken subtests for searching signed and encrypted messages

In [1] Mark showed that the the current code (d7a49e81) is not
consistent in it's handling of subjects of messages with duplicate
message-ids (or in notmuch-speak, of messages with multiple files).
notmuch-search uses indexing order and explicitedly preserves the
first. notmuch-show (apparently) uses alphabetical (or at least xapian
term order) of filenames. In a perfect world we would probably report
all subjects in the json output; at the very least we should be
consistent.

In [1], Mark gave a test that was behaving strangly. This turns out to
be specific to reindexing. I suppose one could argue that picking the
lexicographically last file name is a defensible choice, but it's
almost as easy to take the first, which seems more intuitive. So mark
the current situation as broken.
[1]: id:1503859703-2973-1-git-send-email-markwalters1009@gmail.com
The existing test for notmuch search had the first in filename order
the same as the first indexed, which made it harder to understand what
the underlying behaviour is. Add a file with a lexicographically
smaller name, but later index time to clarify this.
The original intent of this test was to verify that notmuch show was
not crashing when the first file (where headers are being read from)
was deleted. Run the output through some sanitization so that as we
add and delete copies we don't have to update this test.
Changed "" quotes to '' as we're not supposed to dynamically
alter python program (via shell $variable expansion).
Added space to python program to match general python style.
Replaced $* with 'idiomatic' "$@" to serve as better example.
In [1], Vladimir Panteleev observed that the In-Reply-To and
References headers could be wrapped in the 'default' output format of
notmuch-reply, depending on the version of Emacs creating the
message. In my own experiments notmuch-reply sometimes wraps headers
with only one message-id if that message-id is long enough. However it
happens, this causes the previous approach using grep to fail.
Since I found the proposed unwrapping shell fragment in [1] a bit hard
to follow, I decided to write a little python script instead. Then
Tomi suggested a slight generalization of my script, and here we are.

On some system configurations, setting a breakpoint on the "add_file"
function then issuing "continue" in gdb causes the debugger to
seemingly jump over the add_file invocation. This results in a test
failure, as the "Handle files vanishing between scandir and add_file"
subtest expects add_file to be called and fail due to the vanishing
file. The compiler optimization level also plays a role - the problem
can be reproduced with CFLAGS having -O2 but not -Og.
This problem was observed manifesting as a test failure on Travis CI
configured with "dist: trusty" and "sudo: false". It was not
reproducible on a local Docker image of Travis' runtime environment,
so Travis' virtualization infrastructure likely plays a role as well.
* T050-new.sh: Breakpoint notmuch_database_add_message instead of

Somehow the wrapper function doesn't work as a breakpoint; perhaps due
to inlining.
We reorder reading maildir flags to avoid overwriting 'new.tags'. The
inverted status of 'unread' means the maildir flag needs to be checked
a second time.
I backpedalled here on the idea of supporting 'new.tags' without
'unread' in the presence of maildir syncing. For files in 'new/', it
seems quite natural to tag them as 'unread'.
json.tool does not sort or otherwise normalize the order of JSON keys
in its output, which can result in test failures on some test systems.
Instead, use a one-line Python script passed to the interpreter
directly on its command line. Use sort_keys=True for json.dump to
ensure the key order is normalized. The script works with both Python
2 and 3.
* test/test-lib.sh: Update test_expect_equal_json.
We need a way to pass parameters to the indexing functionality on the
first index, not just on reindexing. The obvious place is in
notmuch_database_add_message. But since modifying the argument list
would break both API and ABI, we needed a new name.
I considered notmuch_database_add_message_with_params(), but the
functionality we're talking about doesn't always add a message. It
tries to index a specific file, possibly adding a message, but
possibly doing other things, like adding terms to an existing message,
or failing to deal with message objects entirely (e.g. because the
file didn't contain a message).
So i chose the function name notmuch_database_index_file.
I confess i'm a little concerned about confusing future notmuch
developers with the new name, since we already have a private
_notmuch_message_index_file function, and the two do rather different
things. But i think the added clarity for people linking against the
future libnotmuch and the capacity for using index parameters makes
this a worthwhile tradeoff. (that said, if anyone has another name
that they strongly prefer, i'd be happy to go with it)
This changeset also adjusts the tests so that we test whether the new,
preferred function returns bad values (since the deprecated function
just calls the new one).
We can keep the deprecated n_d_add_message function around as long as
we like, but at the next place where we're forced to break API or ABI
we can probably choose to drop the name relatively safely.
NOTE: there is probably more cleanup to do in the ruby and go bindings
to complete the deprecation directly. I don't know those languages
well enough to attempt a fix; i don't know how to test them; and i
don't know the culture around those languages about API additions or
deprecations.
This patch fixes the 'Deleted first duplicate file does not stop
notmuch show from working' test.
If a message to be shown has several duplicated files, and for some
reason the first file in the list is not available anymore, notmuch
will exit with an error.
This is clearly a problem in the database, but we are not going to let
this problem be a show-stopper. Let's walk through the list, and show
the first existing file.

This patch fixes the "Insert message into folder with trailing /"
test. The problem was insufficient path canonization.
From database's point of view, "Sent" and "Sent/" are different
folders. If user runs (note the last '/'):
notmuch insert --folder=maildir/Sent/ < test.msg
notmuch will create an extra XDIRECTORY record for the folder
'Sent/'. This means that database will have _TWO_ records for _ONE_
physical folder: 'Sent' and 'Sent/'. However, the 'notmuch new'
command will update only records related to the first one (the correct
one).
Now, if user moved the email file (e.g. from 'Sent/new' to
'Sent/cur'), 'notmuch new' will add a record about the new file, but
will not delete the old record.

A leading / in paths in a .gitignore file matches the beginning of the
path, meaning that for patterns without slashes, git will match files
only in the current directory as opposed to in any subdirectory.
Prefix relevant paths with / in .gitignore files, to prevent
accidentally ignoring files in subdirectories and possibly slightly
improve the performance of "git status".
971cdc72cd renamed corpus.mail to
corpora.mail. Although 971cdc72cd
updated some of the remaining corpus.mail references, two remained,
causing the test suite to leave behind an unignored corpora.mail
directory.
The corresponding xapian document just gets more terms added to it,
but this doesn't seem to break anything. Values on the other hand get
overwritten, which is a bit annoying, but arguably it is not worse to
take the values (from, subject, date) from the last file indexed
rather than the first.
There are many other problems that could be tested, but these ones we
have some hope of fixing because it doesn't require UI changes, just
indexing changes.
There are some cases like remote usage where this might cause
problems, but those users can easily customize the variable. The
inconvenience seems to be outweighed by the security benefit for most
users.
