Previously, notmuch show flattened all output, losing information
about the nesting of the MIME hierarchy. Now, the output is properly
nested, (both in the --format=text and --format=json output), so that
clients can analyze the original MIME structure.
Internally, this required splitting the final closing delimiter out of
the various show_part functions and putting it into a new
show_part_end function instead. Also, the show_part function now
accepts a new "first" argument that is set not only for the first MIME
part of a message, but also for each first MIME part within a series
of multipart parts. This "first" argument controls the omission of a
preceding comma when printing a part (for json).
Many thanks to David Edmondson <dme@dme.org> for originally
identifying the lack of nesting in the json output and submitting an
early implementation of this feature. Thanks as well to Jameson Graef
Rollins <jrollins@finestructure.net> for carefully shepherding David's
patches through a remarkably long review process, patiently explaining
them, and providing a cleaned up series that led to this final
implementation. Jameson also provided the new emacs code here.
Previously, the outer multipart part of any multipart/mixed,
multipart/signed, etc. MIME message was silently omitted from the
"notmuch show" output. This prevented any client from correctly
determining to which parts a signature applies, for example.
Now, we actually emit these parts as their own parts. The output is
still flattened---the contained parts are not yet included "within"
the multipart part---so it's still not possible to determine to which
parts a signature applies, but this is one step along the path.
The test suite is updated to reflect this change, (though we'll
eventually want to fix the emacs interface to not display buttons for
the multipart enclosure parts as there's nothing useful for the user
to actually do with them).
This tests "notmuch show" with both --format=text and --format=json on
a message with some non-trivial MIME multipart nesting, (multiple parts
within a multipart/mixed part which is within a multipart/signed part).
The test captures the current behavior (where only the leaf nodes of
the MIME structure are emitted as a flat list---the multipart parts
are effectively ignored). We plan to soon change the json output at
least to emit an actual hierarchy matching the MIME structure, (at
which point we will update this test).
As of gcc 4.6, there are new warnings from -Wattributes along the lines of:
warning: ‘_notmuch_messages’ declared with greater visibility
than the type of its field ‘_notmuch_messages::iterator’
[-Wattributes]
To squelch these, we decorate all such containing structs with
__attribute__((visibility("default"))). We take care to let only the
C++ compiler see this, (since the C compiler would otherwise warn
about ignored visibility attributes on types).
gcc (at least as of version 4.6.0) is kind enough to point these out to us,
(when given -Wunused-but-set-variable explicitly or implicitly via -Wunused
or -Wall).
One of these cases was a legitimately unused variable. Two were simply
variables (named ignored) we were assigning only to squelch a warning about
unused function return values. I don't seem to be getting those warnings
even without setting the ignored variable. And the gcc docs. say that the
correct way to squelch that warning is with a cast to (void) anyway.
This avoids the emacs lisp compiler from emitting warnings on this
replacement code, (which warnings would be hard for us to eliminate
since we didn't write the code but copied it verbatim from emacs 23).
The problem with 'mailx' is that it's not standardized, and it doesn't
allow the -f option, which is pretty important on many sendmail
configurations.

Theses were expected failures only due to a bug in GMime (with
versions of GMime before 2.4.18). As of GMime version 2.4.18 this bug
is fixed and these tests now pass.
Now each caller of notmuch_message_get_tags only gets a new iterator,
instead of a whole new list. In principle this could cause problems
with iterating while modifying tags, but through the magic of talloc
references, we keep the old tag list alive even after the cache in the
message object is invalidated.
This reduces my index search from the 3.102 seconds before the unified
metadata pass to 1.811 seconds (1.7X faster). Combined with the
thread search optimization in b3caef1f06,
that makes this query 2.5X faster than when I started.
Even if the caller never uses the file names, there is little cost to
simply fetching the file name terms. However, retrieving the full
paths requires additional database work, so the expansion from terms
to full paths is performed lazily.
This also simplifies clearing the filename cache, since that's now
handled by the generic metadata cache code.
This further reduces my inbox search from 3.102 seconds before the
unified metadata pass to 2.206 seconds (1.4X faster).
Replace _notmuch_convert_tags with this and simplify
_create_filenames_for_terms_with_prefix. This will also come in handy
shortly to get the message file name list.
This replaces the guts of the filename list and tag list, making those
interfaces simple iterators over the generic string list. The
directory, message filename, and tags-related code now build generic
string lists and then wraps them in specific iterators. The real wins
come in later patches, when we use these for even more generic
functionality.
As a nice side-effect, this also eliminates the annoying dependency on
GList in the tag list.
This performs a single pass over a message's term list to fetch the
thread ID, message ID, and reply-to, rather than requiring a pass for
each. Xapian decompresses the term list anew for each iteration, so
this reduces the amount of time spent decompressing message metadata.
This reduces my inbox search from 3.102 seconds to 2.555 seconds (1.2X
faster).
With the previous commit, unexpected output before or between search results
would be displayed. However, trailing junk from the "notmuch search" output
would still be silently swallowed.
The most common case for an error message from "notmuch search" would be
an invalid command-line, and in that case, there would be no search results
and the trailing error message would get swallowed.
We fix the process sentinel to check for leftover data and add it to the
final buffer. We also add a test case to ensure this works.
This fixes the recently-added emacs-large-search-buffer test. This is
as simple as saving any trailing input and then pre-prepending it on
the next call.
MAny thanks to Thomas Schwinge <thomas@schwinge.name> for tracking
down this problem and contributing a preliminary version of this fix.
Rather than silently swallowing unexpected output, the emacs interface will now
display it. This will allow error messages to actually arrive at the emacs
interface (though not in an especially pretty way). This also allows for easier
investigation of the inadvertent swallowing of search results that span page
boundaries (as demonstrated by the recent added emacs-large-search-buffer test).
The page-boundary bug has been present since a commit from 2009-11-24:
93af7b5745
Many thanks to Thomas Schwinge for tracking that bug down and
contributing the test for it.
The new name is more descriptive of the bug being tested. Also, the test
is rewritten slightly so that it's much more plain to see how the bug
manifests itself, (that messages are droped from the emacs result at
regular intervals). Primarily, this is by collapsing the large blobs
used to inflate the message subjects.
The most recent commit optimized the implementation of this
function. This commit simply updates the relevant comments to match
the new implementation.
The db_files and db_subdirs are unnecessary for unchanged directories.

Looks good (faster than, but provably equivalent to the original code!
notmuch_directory_get_child_* are side-effect free,
db_files/db_subdirs aren't used between where they were set in the old
code and where they are set in the new code, and db_files/db_subdirs
are initialized to NULL when declared).
Another timing data point:
Old code: ./notmuch new 0.77s user 0.28s system 99% cpu 1.051 total

This supports the case of a user running "configure --prefix=/foo" then later
updating the soruce (including the configure script) and re-running make.
In this case, the make invocation will re-run configure. Before this change,
this run of configure would lose the user's carefully chosen prefix. This
is now fixed so that configrue is re-run with the user's options.
Such as:
mkdir build
cd build
../configure
make
This is implemented by having the configure script set a srcdir
variable in Makefile.config, and then sprinkling $(srcdir) into
various make rules. We also use vpath directives to convince GNU make
to find the source files from the original source directory.
In the original json code, search matching nothing would return a
valid, empty json array (that is, "[]"). I broke this in commit
6dcb7592e3 when adding support for
--output=threads|messages|tags. This time, while fixing the bug also
add a test to the test suite to help avoid future regressions.
Now that we understand the bug here, we rename this test to
search-insufficient-from-quoting to clarify the bug being exercised,
(which occurs when the From: line contains an unquoted '.' character).
We also mark these tests as expected failures until the bug gets fixed.
Don't require the caller of _notmuch_doc_id_set_init to pass in a
correct bound; instead compute it from the array. This simplifies the
caller and makes this interface easier to use correctly.
Remove the repeated "sizeof (doc_ids->bitmap[0])" that bothered cworth
by instead defining macros to compute the word and bit offset of a
given bit in the doc ID set bitmap.
The call-process to notmuch in notmuch-query.el was previously sending
stderr into the output buffer. This means that if there is any stderr
the JSON parsing breaks. Unfortunately call-process does not support
sending stderr to a separate buffer or to the minibuffer [0], but it
does support sending it to /dev/null. So we do that here instead.
[0] a bug was filed against emacs (#7842)
Without this patch, it might happen that the remaining time or processing
rate were calculated just after start where nothing was processed yet.
This resulted into division by a very small number (or zero) and the
printed information was of little value.
Instead of printing nonsenses we print only that the operation is in
progress. The estimates will be printed later, after there is enough data.
This was originally intended to help support filenames with spaces in
them, but this actually breaks things when someone sets a command with
a space in it, (such as CC="ccache cc").
Instead, we now only set a custom IFS when acting on the
newline-separated list of files from /sbin/ldconfig.
