9ced40228b python: remove obsolete debian directory
It is unlikely this still works since it has not been updated since
2010. The python packages for debian are now built by the top level
debian/ packaging.

4f5bbaf7e2 lib: add thread subqueries.
This change allows queries of the form

 thread:{from:me} and thread:{from:jian} and not thread:{from:dave}

This is still somewhat brute-force, but it's a big improvement over
both the shell script solution and the previous proposal [1], because it
does not build the whole thread structure just generate a
query. A further potential optimization is to replace the calls to
notmuch with more specialized Xapian code; in particular it's not
likely that reading all of the message metadata is a win here.

68e753a21f NEWS: document notmuch reindex
Describe the introduction of the "reindex" subcommand.  This blurb
acknowledges Subject: instability under reindexing when multiple
copies exist (suggesting that this is something that needn't
necessarily hold up a release).

6aec7a76b9 python: add decrypt_policy argument to Database.index_file()
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.

b1de8e885d test: final named query test works regardless of Xapian FieldProcessor
This test passes with older versions of Xapian as well, because
neither query returns any results.

This should resolve the travis build failure at

7cfa1c6961 lib: return "" rather than NULL from notmuch_thread_get_authors
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.

8e1c3fa5bb test: retrying lock tests are broken when built against older Xapian
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.

bace15c275 test: named query tests are broken when missing Xapian FieldProcessor
Named queries don't work without Xapian FieldProcessor.  Rather than
silently skipping them, we should explictly mark them as broken when

776a2982ae test: searching by absolute date is broken without Xapian FieldProcessor
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.

6c6b0f13ff python: add bindings to access config
The C functions notmuch_database_get_config,
notmuch_database_get_config_list and notmuch_database_set_config are
part of the official C bindings.  So there should also be some python
bindings for them.

Also they are the only way to access the named queries introduced in
b9bf3f44.

The interface of the python functions is designed to be close to the C
functions.

572259885a nmbug: Only error for invalid diff lines in tags/

  Traceback (most recent call last):

With this commit, folks can commit READMEs, .mailmap, etc. to their
nmbug repositories, and 'nmbug diff' and 'status' won't choke on them.
If you want to check for this sort of thing, you can set --log-level
to info or greater.  nmbug will still error if the unrecognized path
is under tags/, since that's more likely to be a user error.

39abd3b522 cli: add support for --no- prefixed boolean and keyword flag arguments
Add transparent support for negating boolean and keyword flag
arguments using --no-argument style on the command line. That is, if
the option description contains a boolean or a keyword flag argument
named "argument", --no-argument will match and negate it.

For boolean arguments this obviously means the logical NOT. For
keyword flag arguments this means bitwise AND of the bitwise NOT,
i.e. masking out the specified bits instead of OR'ing them in.

For example, you can use --no-exclude instead of --exclude=false in
notmuch show. If we had keyword flag arguments with some flags
defaulting to on, say --include=tags in notmuch dump/restore, this
would allow --no-include=tags to switch that off while not affecting
other flags.

As a curiosity, you should be able to warp your brain using
--no-exclude=true meaning false and --no-exclude=false meaning true if
you wish.

Specifying both "argument" and "no-argument" style arguments in the
same option description should be avoided. In this case, --no-argument
would match whichever is specified first, and --argument would only
match "argument".

7ef3b65376 nmbug: Auto-checkout in clone if it wouldn't clobber
We currently auto-checkout after pull and merge to make those more
convenient.  They're guarded against data-loss with a leading
_insist_committed().  This commit adds the same convenience to clone,
since in most cases users will have no NMBPREFIX-prefixed tags in
their database when they clone.  Users that *do* have
NMBPREFIX-prefixed tags will get a warning (and I've bumped the
default log level to warning so folks who don't set --log-level will
see it) like:

  $ nmbug clone http://nmbug.notmuchmail.org/git/nmbug-tags.git
  Cloning into '/tmp/nmbug-clone.g9dvd0tv'...

0a1558471f nmbug: Accept failures to unset core.worktree in clone
Since 6311cfaf (init: do not set unnecessary core.worktree,
2016-09-25, 2.11.0 [1]), Git has no longer set core.worktree when
--separate-git-dir is used.  This broke clone with:

  $ nmbug clone http://nmbug.notmuchmail.org/git/nmbug-tags.git
  Cloning into '/tmp/nmbug-clone.33gg442e'...
  Checking connectivity: 16674, done.
  ['git', '--git-dir', '/home/wking/.nmbug', 'config', '--unset', 'core.worktree'] exited with 5
  $ echo $?
  1

The initial discussion that lead to the Git change is in [2], and
there is some more discussion around this specific change in [3].
There is some useful background on working trees in this 2009 message
[4].  There is also a git-worktree(1) since df0b6cfb (worktree: new
place for "git prune --worktrees", 2015-06-29, 2.5.0 [5]) which grew
the ability to add new worktrees in 799767cc (Merge branch
'es/worktree-add', 2015-07-13, 2.5.0 [6]).  Folks relying on
core.worktree in the --separate-git-dir case fall into the "former
case" in [4], and as Junio pointed out in that message, Git
operations like 'add' don't really work there.

In nmbug we don't want core.worktree, because our effective working
tree is the notmuch database.  By accepting failed core.worktree
unsets, clone will work with Gits older and younger than 2.11.0.

Fixing a bug from 7f2cb3be (nmbug: Translate to Python, 2014-10-03).

cb855d8a9d crypto: signature verification reports valid User IDs
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.

be555b9d27 docs: clean up documentation about decryption policies
Now that the range of sensible decryption policies has come into full
view, we take a bit of space to document the distinctions.

Most people will use either "auto" or "true" -- but we provide "false"
and "nostash" to handle use cases that might reasonably be requested.

Note also that these can be combined in sensible ways.  Like, if your
mail comes in regularly to a service that doesn't have access to your
secret keys, but does have access to your index, and you feel
comfortable adding selected encrypted messages to the index after
you've read them, you could stay in "auto" normally, and then when you
find yourself reading an indexable message (e.g. one you want to be
able to search for in the future, and that you don't mind exposing to
whatever entities have access to your inde), you can do:

    notmuch reindex --decrypt=true id:whatever@example.biz

That leaves your default the same (still "auto") but you get the
cleartext index and stashed session key benefits for that particular
message.

fccebbaeef crypto: add --decrypt=nostash to avoid stashing session keys
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.

29648a137c crypto: actually stash session keys when decrypt=true
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.

6a9626a2fd cli/reindex: destroy stashed session keys when --decrypt=false
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.

076f86025d cli/new, insert, reindex: change index.decrypt to "auto" by default
The new "auto" decryption policy is not only good for "notmuch show"

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.

d137170b23 crypto: record whether an actual decryption attempt happened
In our consolidation of _notmuch_crypto_decrypt, the callers lost
track a little bit of whether any actual decryption was attempted.

Now that we have the more-subtle "auto" policy, it's possible that
_notmuch_crypto_decrypt could be called without having any actual
decryption take place.

not any decryption was actually attempted.

f845fb2a51 cli/show, reply: document use of stashed session keys in notmuch-properties
The stashed session keys are stored internally as notmuch properties.
So a user or developer who is reading about those properties might
want to understand how they fit into the bigger picture.

a1260896f6 cli/show: use decryption policy "auto" by default.
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.
