Add maildir synchronization tests for multiple messages with the same
message-id. As this is not yet implemented in notmuch, some of these
teste are marked as BROKEN.
I use $(< ) operator to avoid fiddling with stripped trailing newlines
from test results which happens when output+=$(command) is used.
Tags in a notmuch database affect all messages with the identical
message-ID. But maildir tags affect individual files. And since
multiple files can contain the identical message-ID, there is not a
one-to-one correspondence between messages affected by tags and flags.
This is particularly dangerous with the 'T' (== "trashed") maildir
flag and the corresponding "deleted" tag in the notmuch
database. Since these flags/tags are often used to trigger
irreversible deletion operations, the lack of one-to-one
correspondence can be potentially dangerous.
For example, consider the following sequence:
1. A third-party application is used to identify duplicate messages
in the mail store, and mark all-but-one of each duplicate with
the 'T' flag for subsequent deletion.
2. A "notmuch new" operation reads that 'T' flag, adding the
"deleted" flag to the corresponding messages within the notmuch
database.
3. A subsequent notmuch operation, (such as a "notmuch dump; notmuch
restore" cycle) synchronized the "deleted" tag back to the mail
store, applying the 'T' flag to all(!) filenames with duplicate
message IDs.
4. A third-party application reads the 'T' flags and irreversibly
deletes all mail messages which had any duplicates(!).
In order to avoid this scenario, we simply refuse to synchronize the
'T' flag with the "deleted" tag. Instead, applications can set 'T' and
act on it to delete files, or can set "deleted" and act on it to
delete files. But in either case the semantics are clear and there is
never dangerous propagation through the one-to-many mapping of notmuch
message objects to files.
This change reworks these tests in several ways:
1. Bring tests into "new" test style preferring test_expect_equal over
test_expect_success in almost all cases.
2. Don't emit test results for intermediate items not actually being
tested, (things like "no new messages", "search for message",
etc.). Those things are already covered by existing tests such as
"basic" or "search" and only serve to obscure what's actually being
tested.
3. Change sense of the test showing failure to rename a file from
"new" to "cur" when "cur" doesn't exist.
In this case, notmuch should detect that this is not a maildir and
should not attempt to do any renaming of the file.
4. Extend dump/restore test to also exercise addition of tag, not just
removal.
Both items #3 and #4 above show shortcomings in the current
implementation. These are currently resulting in test results of FAIL
and indicate bugs that need to be fixed.
This adds group [maildir] and key 'synchronize_flags' to the
configuration file. Its value enables (true) or diables (false) the
synchronization between notmuch tags and maildir flags. By default,
the synchronization is disabled.
This patch allows bi-directional synchronization between maildir
flags and certain tags. The flag-to-tag mapping is defined by flag2tag
array.
The synchronization works this way:
1) Whenever notmuch new is executed, the following happens:
o New messages are tagged with configured new_tags.
o For new or renamed messages with maildir info present in the file
name, the tags defined in flag2tag are either added or removed
depending on the flags from the file name.
2) Whenever notmuch tag (or notmuch restore) is executed, a new set of
flags based on the tags is constructed for every message and a new
file name is prepared based on the old file name but with the new
flags. If the flags differs and the old message was in 'new'
directory then this is replaced with 'cur' in the new file name. If
the new and old file names differ, the file is renamed and notmuch
database is updated accordingly.
The rename happens before the database is updated. In case of crash
between rename and database update, the next run of notmuch new
brings the database in sync with the mail store again.
We have test names like maildir-sync now, so it's cleaner if the
temporary files created are named things like maildir-sync-10.out
rather than maildir-10.out. Presumably the extra stripping here came
from naming conventions in git's test suite.
Possilby used by more systems, and besides the code wasn't really
working properly anyway.

It's not working properly; the current message is jumping around and the
tags not really added/removed properly.

kill-this-buffer appears to be a function intended specifically for
use in the menu bar, and causes problem killing notmuch buffers when
multiple frames have been used. This patch replaces kill-this-buffer
with notmuch-kill-this-buffer, which in turn just simply calls
(kill-buffer (current-buffer)).
This is part of an effort to avoid proliferation of excessive
top-level notmuch commands. Also, "raw" better captures the
functionality here, (as opposed to "cat" which is a fairly oblique
reference to a bad Unix abbreviation whose metaphor doesn't work here
since "notmuch cat" operates only on a single message and hence cannot
"con'cat'enate" anything).
This patch modifies the following commands to access the messages via
cat subcommand:
- view/save attachments ('v', 'w'),
- view a raw message ('V') and
- pipe a message to a command ('|').
With this patch, it is straightforward to use notmuch emacs interface
with a remote database accessed over SSH. To do this, it is sufficient
to redefine notmuch-command variable to contain the name of a script
containing:
ssh user@host notmuch "$@"
If the ssh client has enabled connection sharing (ControlMaster option
in OpenSSH), the emacs interface is almost as responsive as when
notmuch is invoked locally.
This command outputs a raw message matched by search term to the
standard output. It allows MUAs to access the messages for piping,
attachment manipulation, etc. by running notmuch cat rather then
directly access the file. This will simplify the MUAs when they need
to operate on a remote database.

add missing "test_done" to new test script to avoid "Unexpected exit"
error.
This was too rude of a thing to do and could easily introduce
problems, (as reported by Rob Browning whose environment required some
HOME-specific things for shell startup).
Instead, implement more focused changes to ensure that particular file
in $HOME don't cause problems. Specifically, we fix known problems
with ~/.signature and ~/.mailrc here.
The original mails used to pupulate the mail corpus had had their
attachments (obnoxiously) scrubbed by the pipermail mail archiver.
Since we actually want to test the handling of attachments, this is
less than useful. Restore these files from my own collection, (with
some Received and similar headers pruned).
I still don't know everything about how I want search order to be
customizable, but I do like the current defaults, (namely, performing
a new search gives results newest first, but performing a saved search
like "tag:inbox" gives results as oldest first).
Until we come up with a better plan for people to select what *they*
want, (rather than just getting what I want), let's codify the current
results in the test suite.
After any emacs test failure, the tmp.emacs directory will have this
run_emacs script in it which the user can use to run emacs within the
test suite environment, (pointing at the test suite's notmuch
database, using the local notmuch command-line program, and the local
notmuch emacs lisp code).
This change affects both text and json formats. Now, text format
behaves as before commit 6dcb7592, but json format is changed.
Earlier, the empty search returned '[]', now it returns ''. The emacs
interface seems not to be affected by this change.
My scripts expect that empty search result is actually empty. Since
commit 6dcb7592, even empty search prints a newline character and this
breaks my scripts.
This patch adds a test for this bug. In the test I cannot use
test_expect_equal function as $() operator suppresses the final
newline and this kind of difference is not detected.

This is almost totally clearn. The (mangled) names of the Xapian
exception classes appear here. That's not actually desired, as the
notmuch library is never intended to throw any exceptions. But Xapian
does not currently provide a mechanism for us to avoid these.
This option wasn't having the desired effect, and sure enough, the
documentation states that it only affects the linking of libraries
that appear after this option on the command line. So put it early for
the desired effect.
This prevents any of the private functions from being leaked out
through the library interface (at least when compiling with a
recent-enough gcc to support the visibility pragma).
These various functions and data are all used only locally, so should
be marked static. Ensuring we get these right will avoid us accidentally
leaking unintended symbols through the library interface.
Previously, we were building the final binary with this option, but not
the library. The library can benefit from it as well, (as pointed out
by Debian's lintian).
This increment is for the recently-added functions:
notmuch_query_get_query_string
notmuch_query_get_sort
These were recently added to the library interface, but the library
version was not incremented at that time, (shame on me).
This fits with our general build philosophy of checking at configure
time for desired support, (rather than putting platform-specific
conditionals into our Makefiles).
