This at least allows distinguishing between out of memory and Xapian
exceptions. Adding finer grained status codes would allow different
Xapian exceptions to be preserved.
Adding wrappers allows people to transition gradually to the new API,
at the cost of bloating the library API a bit.
Fix the following warning produced by clang 3.5.0:
notmuch-search.c:730:25: warning: initializing 'void *' with an
expression of type 'const notmuch_opt_desc_t (*)[4]' discards
qualifiers [-Wincompatible-pointer-types-discards-qualifiers]

When the shell builtin `command -v` operates normally, it either
prints the path of the arg given to it and returns zero -- or it
returns nonzero and prints nothing.
In abnormal situations something might be printed to stderr and
in that case we want to know about it; therefore the used
command -v stderr redirections to /dev/null have been removed.
The `hash` (builtin) command in ksh returns zero even the arg
given to is is not found in path. For that and for consistency
the one appearance of it has been converted to `command -v`.
For those messages, compute a synthetic Message-ID based on the SHA1
of the whole message, in the same way that notmuch would do. See:
http://git.notmuchmail.org/git/notmuch/blob/HEAD:/lib/sha1.c
To do the above, rewrite get_message_id() to accumulate header lines,
parse them to check for Message-ID, and fallback to SHA1 computation
if it is not present.
Thanks to:
- Jan N. Klug for preliminary versions of this patch
- Tomi Ollila for suggesting an elegant implementation
Besides generally cleaning up the code and separating the general
content ID handling from the w3m-specific code, this fixes several
problems.
Foremost is that, previously, the code roughly assumed that referenced
parts would be in the same multipart/related as the reference.
According to RFC 2392, nothing could be further from the truth:
content IDs are supposed to be globally unique and globally
addressable. This is nonsense, but this patch at least fixes things
so content IDs can be anywhere in the same message.
As a side-effect of the above, this handles multipart/alternate
content-IDs more in line with RFC 2046 section 5.1.2 (not that I've
ever seen this in the wild). This also properly URL-decodes cid:
URLs, as per RFC 2392 (the previous code did not), and applies crypto
settings from the show buffer (the previous code used the global
crypto settings).
Unibyte strings are meant for representing binary data. In practice,
using unibyte versus multibyte strings affects *almost* nothing. It
does happen to matter if we use the binary data in an image descriptor
(which is, helpfully, not documented anywhere and getting it wrong
results in opaque errors like "Not a PNG image: <giant binary spew
that is, in fact, a PNG image>").
`notmuch-get-bodypart-content' could do two very different things,
depending on conditions: for text/* parts other than text/html, it
would return the part content as a multibyte Lisp string *after*
charset conversion, while for other parts (including text/html), it
would return binary part content without charset conversion.
This commit completes the split of `notmuch-get-bodypart-content' into
two different and explicit APIs: `notmuch-get-bodypart-binary' and
`notmuch-get-bodypart-text'. It updates all callers to use one or the
other depending on what's appropriate.
The new function, `notmuch-get-bodypart-binary', replaces
`notmuch-get-bodypart-internal'. Whereas the old function was really
meant for internal use in `notmuch-get-bodypart-content', it was used
in a few other places. Since the difference between
`notmuch-get-bodypart-content' and `notmuch-get-bodypart-internal' was
unclear, these other uses were always confusing and potentially
inconsistent. The new call clearly requests the part as undecoded
binary.
This is step 1 of 2 in separating `notmuch-get-bodypart-content' into
two APIs for retrieving either undecoded binary or decoded text.
Questions related to the way that probabilistic prefixes and phrases
are handled come up quite often and it is nicer to have the documentation self contained. Hopefully putting it in subsections prevents it from being overwhelming.
Adds new entry to the NEWS file, and updates the search terms section
of the man page. The search terms section needs to be updated again
once the new section in the documentation covering probablistic terms
has been committed.
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
This feature will exist in all newly created databases, but there is
no upgrade provided for it. If this flag exists, it indicates that
the database was created after the indexed MIME-types feature was
added.
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.
We set header-line-format to the message subject, but if the subject
contains percents, the next character is interpreted as a formatting
control, which is not desired.
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.
_thread_set_subject_from_message sometimes replaces the subject, making the
cur_subject point to free'd memory

The TAB-initiated address completion generates completion candidates
synchronously, blocking the UI. Since this can take long time, it is
better to let the use know what's happening.
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.
Currently the thread is named based on either the oldest or newest
matching message (depending on the search order). If this message has
an empty subject, though, the thread will show up with an empty
subject in the search results. (See the thread starting with
`id:1412371140-21051-1-git-send-email-david@tethera.net` for an
example.)
This changes the behavior so it will use a non-empty name for the
thread if possible. We name threads based on (a) non-empty matches for
the query, and (b) the search order. If the search order is
oldest-first (as in the default inbox) it chooses the oldest matching
non-empty message as the subject. If the search order is newest-first
it chooses the newest one.
Make a new customizable variable instead of relying on
message-cite-function because the default for the latter changed
between emacs releases.
The defcustom is borrowed from the message.el source, with minor
modifications.
The faces used when washing messages should be notmuch specific and
inherit from the underlying emacs face rather than using it
directly. This allows the washed face to be modified without requiring
the modification of the underlying face.
