As mentioned by Jani Nikula in id:87vcccp4y3.fsf@nikula.org, some cases
of maildir synchronization are not covered by our tests. Let's add the
missing tests.
Some MUA's like mutt show the difference between "new" emails living in maildir
directory new/, and "old" emails living in maildir directory cur/. However
notmuch tag unconditionally moves selected messages from new/ to cur/, even if
no maildir synchronized tag is changed.
While maildir specification forbids messages with tags living in new/, there is
no need to move messages to cur/ when no maildir synchronized tag is changed.
Thus notmuch can remain transparent with respect to other MUA's.

RFC 2047 states that the encoding and charset in an encoded word are
case-insensitive, so force them to lower case in the reply test. This
fixes an issue caused by GMime versions (somewhere between 2.6.10 and
2.6.16), which changed the capitalization of the encoding.
Previously, reply's default text format used an odd mix of RFC 2045
MIME encoding for the reply template's body and some made-up RFC
2822-like UTF-8 format for the headers. The intent was to present the
headers to the user in a nice, un-encoded format, but this assumed
that whatever ultimately sent the email would RFC 2047-encode the
headers, while at the same time the body was already RFC 2045 encoded,
so it assumed that whatever sent the email would *not* re-encode the
body.
This can be fixed by either producing a fully decoded UTF-8 reply
template, or a fully encoded MIME-compliant RFC 2822 message. This
patch does the latter because it is
a) Well-defined by RFC 2822 and MIME (while any UTF-8 format would be
ad hoc).
b) Ready to be piped to sendmail. The point of the text format is to
be minimal, so a user should be able to pop up the template in
whatever editor they want, edit it, and push it to sendmail.
c) Consistent with frontend capabilities. If a frontend has the
smarts to RFC 2047 encode the headers before sending the mail, it
probably has the smarts to RFC 2047 decode them before presenting
the template to a user for editing.
Also, as far as I know, nothing automated consumes the reply text
format, so changing this should not cause serious problems. (And if
anything does still consume this format, it probably gets these
encoding issues wrong anyway.)
Previously, the References header code seemed to assume
notmuch_message_get_header would return NULL if the header was not
present, but it actually returns "". As a result of this, it was
inserting an unnecessary space when concatenating an empty or missing
original references header with the new reference.
This shows up in only two tests because the text reply format later
passes the whole reply template through g_mime_filter_headers, which
has the side effect of stripping out this extra space.
This switches `notmuch-mua-reply' and `notmuch-query-get-threads' to
the S-exp format. These were the last two uses of the JSON format in
the Emacs frontend.
While looked good on paper, its attempted use caused confusion, complexity,
and potential for information leak when passed through wrapper scripts.
For slimmer code and to lessen demand for maintenance/support the set of
commits which added top level --stderr= option is now reverted.
The find option syntax `-perm +111` is deprecated gnu find feature.
The replacement `( -perm -100 -o -perm -10 -o -perm 1 )` should also
work outside of the GNU domain.
In addition to being the Right Thing to do, this noticeably improves
the time taken to display the first page of search results, since it's
roughly an order of magnitude faster than the JSON parser.
Interestingly, it does *not* significantly improve the time to
completely fill a large search buffer because for large search
buffers, the cost of creating author invisibility overlays and
inserting text (which slows down with more overlays) dominates.
However, the time required to display the first page of results is
generally more important to the user experience.
Previously, search started the async notmuch process directly. Now,
it uses `notmuch-start-notmuch'. This simplifies the process sentinel
a bit and means that we no longer have to worry about errors
interleaved with the JSON output.
We also update the tests of Emacs error handling, since the error
output is now separated from the search results buffer.
We now check error handling more carefully in the last test in
test/emacs and we're about to add more error handling tests. (This
was also a strange place for this test, since it had nothing to do
with large search buffers.)
This unifies the part button actions and the underlying part action
functions into single interactive command that simply applies to the
part containing point using the just-added part p-list text property
instead of button properties. Since all part actions can be performed
by applying the appropriate mm function to an mm-handle, this patch
abstracts out the creation of mm handles, making the implementations
of the part commands trivial. This also eliminates our special
handling for part save in favor of using the appropriate mm function.
This necessarily modifies the way we handle the default part button
action, but in a way that does not change the meaning of the
notmuch-show-part-button-default-action defcustom.
Since these commands are no longer specific to buttons, this patch
eliminates the extra metadata stored with each button. This also
eliminates one rather special-purpose macro for a collection of
general purpose part handling utilities.
--stderr=FILE tests were added to test/help-test as it is the one
doing most global option testing. Also, it was simplest to test
this new option using `notmuch help` command.
Presently, the code which finds the parent of a message as it is being
added to the database assumes that the first Message-ID-like substring
of the In-Reply-To header is the parent Message ID. Some mail clients,
however, put stuff other than the Message-ID of the parent in the
In-Reply-To header, such as the email address of the sender of the
parent. This can fool notmuch.
The updated algorithm prefers the last Message ID in the References
header. The References header lists messages oldest-first, so the last
Message ID is the parent (RFC2822, p. 24). The References header is
also less likely to be in a non-standard
syntax (http://cr.yp.to/immhf/thread.html,
http://www.jwz.org/doc/threading.html). In case the References header
is not to be found, fall back to the old behavior.
V2 of this patch, incorporating feedback from Jani and (indirectly)
Austin.
The use of realpath(3) in
commit 58ed67992d
Author: Jani Nikula <jani@nikula.org>
Date: Sun Apr 7 20:15:03 2013 +0300
cli: config: do not overwrite symlinks when saving config file
broke config file save when the file does not exist, which results in
'notmuch setup' always failing to create a new config file.
Fix by checking ENOENT from realpath(3).
Use realpath to canonicalize the config path before writing.
Previously 'notmuch setup' and 'notmuch config set' overwrote the
config file even if it was a symbolic link.
We now have a notmuch_config_is_new() function to query whether a
config was created or not. Change the notmuch_config_open() is_new
parameter into boolean create_new to determine whether the function
should create a new config if one doesn't exist. This reduces the
complexity of the API.
When execution of tests is interrupted by signal coming outside of the
test system itself, output just one line "interrupted by signal <num>"
message to standard output. This distinguishes the case from internal
exit and reduces noise.
Set the variable '$test_subtest_name' in all functions which starts
a new test and use that variable in all functions that output
test results.
Additionally output the latest '$test_subtest_name' in case of
abnormal exit, to avoid confusion.
Instead of checking immediately for the watched process, delay a
minute, or in the case that process-attributes returns nil, for two
minutes. This is intended to cope with the case that
process-attributes is unimplimented, and returns always returns nil.
In this case, the watchdog check is the same as the two minute limit
imposed by timeout.
The TERM environment variable is set to 'dumb' when running tests, but
the original value of it is stored for echoing colors and running emacs
(somewhat interactively) in detached session. Emacs requires some
terminal control sequences to be available for interactive operation.
In case original TERM is (also) 'dumb' (or unset/empty) emacs cannot
run interactively. To fix this problem dtach (and emacs as it's child
process) is run with TERM=vt100 in case original TERM was unset, empty
or 'dumb'. This way there is a chance to run emacs tests with different
user terminals and potentially find problems there.
This test also serves as documentation of the quoting
requirements. The comment lines are so that it exactly matches the man
page. Nothing more embarrassing than having an example in the man page
fail.
The (now fixed) bug that this test revealed is that unquoted
message-ids with whitespace or other control characters in them are
split into several tokens by the Xapian query parser.
This is based on the similar test for notmuch restore, but the parser
in batch tagging mode is less tolerant of a few cases, in particular
those tested by illegal_tag.
We recently switched to popping up a buffer to report CLI errors, but
this was too intrusive, especially for transient errors and especially
since we made fewer things ignore errors. This patch changes this to
display a basic error message in the minibuffer (using Emacs' usual
error handling path) and, if there are additional details, to log
these to a separate error buffer and reference the error buffer from
the minibuffer message. This is more in line with how Emacs typically
handles errors, but makes the details available to the user without
flooding them with the details.
Given this split, we pare down the basic message and make it more
user-friendly, and also make the verbose message even more detailed
(and more debugging-oriented).
This switches the new batch-tag format away from using a home-grown
hex-encoding scheme for message IDs in the dump to simply using Xapian
queries with Xapian quoting syntax.
This has a variety of advantages beyond presenting a cleaner and more
consistent interface. Foremost is that it will dramatically simplify
the quoting for batch tagging, which shares the same input format.
While the hex-encoding is no better or worse for the simple ID queries
used by dump/restore, it becomes onerous for general-purpose queries
used in batch tagging. It also better handles strange cases like
"id:foo and bar", since this is no longer syntactically valid.
When we switch to using regular Xapian queries in the dump format, \n
will cause problems, so we disallow it. Specially, while Xapian can
quote and parse queries containing \n without difficultly, quoted
queries containing \n still span multiple lines, which breaks the
line-orientedness of the dump format. Strictly speaking, we could
still round-trip these, but it would significantly complicate restore
as well as scripts that deal with tag dumps. This complexity would
come at absolutely no benefit: because of the RFC 2822 unfolding
rules, no amount of standards negligence can produce a message with a
message ID containing a line break (not even Outlook can do it!).
Hence, we simply disallow it.
This patch corrects several undesirable behaviours:
1) Empty files were not detected, leading to buffer read overrun.
2) An initial blank line cause restore to silently abort
3) Initial comment line caused format detection to fail
notmuch_json_show_sanitize replaced "filename" field values even in part
structures, where the value is predictable. Make it only normalize the
filename value if it is an absolute path (begins with slash), which is
true of the Maildir filenames that were intended to be normalized away.
