This is a simplified version of a patch originally by Michal Sojka
<sojkam1@fel.cvut.cz> which is designed to have the same performance
benefits. Michal said the following:
When notmuch new is run for the first time, it is not necessary to
defer maildir flags synchronization to later because we already know
that no files will be removed.
Performing the maildinr flag synchronization immediately after the
message is added to the database has the advantage that the message
is likely hot in the disk cache so the synchronization is faster.
Additionally, we also save one database query for each message,
which must be performed when the operation is deferred.
Without this patch, the first notmuch new of 200k messages (3 GB)
took 1h and 46m out of which 20m was maildir flags
synchronization. With this patch, the whole operation took only 1h
and 36m.
Unlike Michal's patch, this version does the deferral for any new
message, rather than doing it only on the first run of "notmuch new".
Here's a bitty patch to the vim plugin; it now calculates the primary email
of the user based on a call to notmuch config. There's still a lot of work
that needs to get done on notmuch.vim, e.g., the ability to have multiple
emails/accounts.
Currently, whenever we call index_terms multiple times for a single
field, the term generator is being reset to position 0 each time. This
means that with text such as:
To: a@b.c, x@y.z
one can get a bogus match by searching for:
To: a@y.c
Thanks to Mark Anderson for reporting the bug, (and providing a nice,
minimal test case that inspired what is used here).
With talloc, we were already freeing all memory by the time we exited
the loop, but that didn't help with excess use of memory inside the
loop, (which was mostly from tallocing some objects with the incorrect
parent).
Thanks to Andrew Tridgell for sitting next to me and teaching me to
use talloc_report_full to find these leaks.
A new "folder:" prefix in the query string can now be used to match
the directories in which mail files are stored.
The addition of this feature causes the recently added
search-by-folder tests to now pass.
This is a new feature which is not implemente yet, so these tests mostly
fail currently. A subsequent commit will add the feature and cause these
tests to start passing.
These tests verify that we can search for containing folders of mail files
by word or by phrase and that the search terms are updated correctly when
directories are renamed.
Using the local talloc context ensures that the memory we are using
here will be freed shortly, (rather than hanging on for a long time
with the notmuch database object).
Convert the meta information to point to the notmuchmail.org repository, rather
than the old cnotmuch location. I will delete the "cnotmuch" package
from http://pypi.python.org/pypi/cnotmuch and create a new "notmuch"
package there that contains the current versions.
Also bump the version number to 0.4. I will need to upgrade the API
first before I can release the 0.5 of the bindings, there are still some
methods missing.

This reduces thread search's 1+2t Xapian queries (where t is the
number of matched threads) to 1+t queries and constructs exactly one
notmuch_message_t for each message instead of 2 to 3.
notmuch_query_search_threads eagerly fetches the docids of all
messages matching the user query instead of lazily constructing
message objects and fetching thread ID's from term lists.
_notmuch_thread_create takes a seed docid and the set of all matched
docids and uses a single Xapian query to expand this docid to its
containing thread, using the matched docid set to determine which
messages in the thread match the user query instead of using a second
Xapian query.
This reduces the amount of time required to load my inbox from 4.523
seconds to 3.025 seconds (1.5X faster).
We really want to change the thread subject at the same time we set
the date, (if the sort order indicates this is necessary). The
previous code for setting the thread subject was sensitive on the
query sort when adding matching messages. An independent bug fix is
about to change that query sort order, so we remove the dependency on
it here.
This reverts commit f22a7ec1e2.
Interrupting the test suite due to an actual bug in a test script
would be just fine, but interrupting the run of the entire test suite
at the first test failure is unacceptable.
Previously, this directory was only preserved for failing tests. But
it's important to be able to easily debug known-broken tests, so
preserve the actual vs. expected output for those as well.
Use varying dates in the test messages to test the order authors are
listed in. Add tests with repeated author names and unusual date
ordering. Most of these are broken at the moment, but will be fixed
shortly.
Edited-by: Carl Worth <cworth@cworth.org>: Also update the expected
results for existing emacs tests that currently codify the incorrect
author ordering, (and similarly note them as broken in the current
test suite).
The removed expressions, which were used to ensure that citations were
both preceded and followed by a blank line, were poorly implemented
and caused a regexp stack overflow on messages more than a few
thousand lines long.
Incremental search does not match strings that span a
visible/invisible boundary. This results in failure to correctly
isearch for authors in `notmuch-search' mode if the name of the author
is split between the visible and invisible components of the authors
string. To avoid this, attempt to truncate the visible component of
the authors string on a boundary between authors, such that the
entirety of an author's name is either visible or invisible.
Appease the test suite by using the true name for the Fcc directory
path, otherwise a value for `notmuch-database-path' which includes
symbolic links causes test suite failures.
When a test fails, a tmp.<testname> file is left behind. These files
are useful for the person debugging the test failure, but are never
anything we want to commit.
Edited-by: Carl Worth <cworth@cworth.org>: Changed from tmp.emacs to
tmp.* and added explanation in the commit message.
Previously, we would only scan a directory if the filesystem
modification time was strictly newer than the database modification
time for the directory. This would cause a problem for systems with an
unstable clock, (if a new mail was added to the filesystem, then the
system clock rolled backward, "notmuch new" would not find the message
until the clock caught up and the directory was modified again).
Now, we always scan the directory if the modification time of the
directory is not exactly the same between the filesystem and the
database. This avoids the problem described above even with an
unstable system clock.
This was a misfeature where notmuch had extra code that just threw
away legitimate information. It was never indexing an initial "Re"
term in a subject. But some users have legitimately wanted to search
for this term.
The original code was written this way merely for strict compatiblity
with the indexing performed by sup, but we're not taking advantage of
that now anyway.
As mentioned in the recent test commits, this also fixes the missing
'[' and ']' characters in the --format=json variant of "notmuch search
--output=tags" as well.
This testing *does* capture the bug of missing '[' and ']' characters
int "notmuch search --output=tags" case. This is another manifestation
of the same bug causing the missing final newline (as mentioned in the
previous commit).
This code simply wasn't being exercised by the test suite before, so
this will be useful.
Meanwhile, there's currently a bug in "notmuch search --output=tags"
in that it doesn't print a final newline. But the current test suite
isn't able to catch this bug since the $() construct of the shell
doesn't preserve the distinction of whether the final newline is
present or not.
Emacs22 lacks apply-partially and mouse-event-p, so define them if emacs
version is less than 23. With this change, I was able to begin using
notmuch in emacs22.
The definitions of apply-partially and mouse-event-p are copied from
the emacs 23 distribution, (which is distributed under the GPLv3+ just
as notmuch).
This test script does some initial test setup (generating a few
messages), which is all well and good, but we don't need to print that
as a test result---particularly since the test result was effectively
hard-coded to always pass.
When test_begin_subtest is not followed by corresponding test_expect_equal,
the output of the rest of the test script is errornously suppressed. Add
code to detect these bugs in test scripts.
Break notmuch-test whenever a test script returns non-zero status.
This happens either when some test from the script fails or when there
is an error in the script.
This is especially useful in the latter case since the error may not
appear in the final aggregated results.
The newline was removed from say_color in commit 222926ab to allow
printing test status in the beginning of the line. Error messages are
never followed by other text so we add the newline to error function.
Git-style tests (test_expect_success etc.) suppress stdout and stderr
unless -v is given. Notmuch-style tests (created by test_begin_subtest
and test_expect_equal) do not have this behavior so implement it the
same.
Additionally, for both test styles, the test-lib.sh is changed so that
the content of suppressed stdout and stderr is shown in case of failed
test.
Finally a test for this functionality is added to basic tests.
Explained-by: Carl Worth: This gives convenient keybindings for
navigating the file and for quitting from the buffer, (since, with a
raw message file the user will generally want to just view the
message, not edit it).
With --modversion we were asking for output that we were just throwing
away anyway. The --exists option does just what we want, (no output
and communivating only via return value).
Also, --exists allows for testing versions of the package as well.
