Fix bug reported in id:20160606124522.g2y2eazhhrwjsa4h@flatcap.org
Although the C99 standard 6.10 is a little non-obvious on this point,
the docs for e.g. gcc are unambiguous. And indeed in practice with the
extra space, this code fails
#include <stdio.h>
#define foo (x) (x+1)
int main(int argc, char **argv){
printf("%d\n",foo(1));
}
This has been wrong since bbbdf0478e, but the race condition was not
previously been (often?) triggered in the tests. With the DB_RETRY_LOCK
patches, it manifests itself as a deadlock.
This support will be present only if the appropriate version of xapian
is available _and_ the user did not disable the feature when
building. So there really needs to be some way for the user to check.
Xapian 1.3 has introduced the DB_RETRY_LOCK flag (Xapian bug
275). Detect it in configure and optionally use it. With this flag
commands that need the write lock will wait for their turn instead of
aborting when it's not immediately available.
Amended by db: allow disabling in configure

A few simple things that applies well to test/notmuch-test.sh
- Shell does pathname expansion also without doing `echo ...` in subshell.
- Redirections >/dev/null 2>/dev/null hide (improbable but) potential
serious errors; adding -f to rm instead.
- Inter-file capitalization consistency in comments.
- Unnecesary space removal.
Previously if a marking read tag change (i.e., removing the unread
tag) failed for some reason, such as a locked database, then no more
mark read tag changes would be attempted in that buffer.
This handles the error more gracefully. There is not much we can do
yet about dealing with the error itself, and marking read is probably
not important enough to warrant keeping a queue of pending changes or
anything.
However this commit changes it so that
- we do try and make future mark read tag changes.
- we display the tag state correctly: i.e. we don't display the tag as
deleted (no strike through)
- and since we know the tag change failed we can try to mark this
message read in the future. Indeed, since the code uses the
post-command hook we will try again on the next keypress (unless the
user has left the message).
We indicate to the user that these mark read tag changes may have
failed in the header-line.
The trick of having a common header file doesn't work to share between
test scripts, so make an include file in the test directory.
The use of #include <notmuch-test.h> looks slightly pretentious, but
the include file is not actually in the current (temporary) directory.
Place PYTHONPATH to the environment when python is executed in a way
that current shell environment is not affected. This also allows adding
the old value of PYTHONPATH to the end of the new value (otherwise it
would have been appended again and again when test_python is called).
At the same time, use -B option to avoid writing .pyc files to
bindings/python/* (which are not cleared out by distclean).
Drop the (unused) prefix code which preserved the original stdout of the
python program and opened sys.stdout to OUTPUT. In place of that there
is now note how (debug) information can be printed to original stdout.
Previously LD_LIBRARY_PATH was exported (and environment changed)
in the middle of test case execution, when a function setting it
was called.
Previously the old contents of LD_LIBRARY_PATH was lost (if any)
when it was re-set and exported. In some systems the old contents of
LD_LIBRARY_PATH was needed to e.g. locate suitable gmime library.
Escaping $PWD makes this work in directories like 'foo"bar'...
Cd'ing always makes the working directory to be consistent whether
--body option was used or not (when using emacsclient, but cd'ing
when using emacs does not cause any harm).
Note that documentation of `insert-file` expects programs to
call `insert-file-contents` instead. In our simple case
`insert-file` works better as it does some good checks that we'd
have to implement ourselves. Look lisp/files.el in emacs sources
for more information.
In scripts that include test-lib-common.sh but not test-lib.sh
the die() implementation needs to be a bit different due to
fd redirection differences. test-lib-common.sh implements die()
only if it was not implemented already.
Added die() function to test-lib.sh with the following first use of it:
If notmuch new fails during email corpus addition the database is
most probably inexistent or broken and the added corpus would be
unusable while running single tests, giving misleading failures
("only" full 'make test' cleans out old corpus).

Setting locale environment variables (LC_* and LANG) to e.g.
en_US.utf8 works fine on Linux, and that is what locale -a
returns (in Linux). However this does not work e.g. in some *BSD
systems.
In these systems, en_US.UTF-8 works. This also works in Linux
systems (which may look like a surprising thing on the first sight(*)).
But that *UTF-8 format seems to be widely used in the Linux system:
Grep it through the files in /etc/, for example.
Easy way to test: Run the following command lines. First should
complain about setting locale failed, and second should not.
$ LC_ALL=en_US.UTF-1 perl -e ''
$ LC_ALL=en_US.UTF-8 perl -e ''
(*) and who knows what the "standard" is...
sphinx-build emits a minor warning:
[...]doc/man7/notmuch-search-terms.rst:223: WARNING: Block quote ends without a blank line; unexpected unindent.
And the tabular representation of boolean or probabilistic prefixes
currently renders like this when i view it in man:
┌───────────────────────────┬────────────────────────────┐
│Boolean │ Probabilistic │
└───────────────────────────┴────────────────────────────┘
│ tag: id: │ from: to: │
│ │ │
│ thread: folder: │ subject: attach‐ │
│ path: │ ment: mimetype: │
└───────────────────────────┴────────────────────────────┘
This isn't just ugly: it's confusing, because it seems to imply that
some of the prefixes in the left-hand column are somehow related to
specific other prefixes in the right-hand column.
The Definition List representation introduced by this patch should be
simpler for readers to understand, and doesn't have the warning.
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
Currently, http://packages.python.org/notmuch/ goes through a series
of redirections and ends up pointing to readthedocs. Since we're
using readthedocs directly anyway, just point to it directly.
readthedocs are also now sensibly using a separate domain
(readthedocs.io) for their hosted documentation as distinct from their
own domain (readthedocs.org), so use the correct tld.
Cleaned the following whitespace in lib/* files:
lib/index.cc: 1 line: trailing whitespace
lib/database.cc 5 lines: 8 spaces at the beginning of line
lib/notmuch-private.h: 4 lines: 8 spaces at the beginning of line
lib/message.cc: 1 line: trailing whitespace
lib/sha1.c: 1 line: empty lines at the end of file
lib/query.cc: 2 lines: 8 spaces at the beginning of line
lib/gen-version-script.sh: 1 line: trailing whitespace
It's already kindof gross that this is hardcoded in two different
places. We will also need these later in field processors calling back
into the query parser.
Most of the infrastructure here is general, only the validation/dispatch
is hardcoded to a particular prefix.
A notable change in behaviour is that notmuch-config now opens the
database e.g. on every call to list, which fails with an error message
if the database doesn't exit yet.
Since xapian provides the ability to restrict the iterator to a given
prefix, we expose this ability to the user. Otherwise we mimic the other
iterator interfances in notmuch (e.g. tags.c).
This is a thin wrapper around the Xapian metadata API. The job of this
layer is to keep the config key value pairs from colliding with other
metadata by transparently prefixing the keys, along with the usual glue
to provide a C interface.
The split of _get_config into two functions is to allow returning of the
return value with different memory ownership semantics.
The Ruby bindings were missing a way to get all the tags of the
database. Now you should be able to access this with the public
instance method `all_tags` of your database object.
Example of use:
notmuchdb = Notmuch::Database.new path, { :create => false,
:mode => Notmuch::MODE_READ_ONLY }
my_tags = notmuchdb.all_tags
my_tags.each { |tag|
print tag
}
my_tags.destroy!
Amended by db: improve error reporting, add test
Files in test directories had only copyright of a single individual,
of which code was adapted here as a base of the test system.
Since then many Notmuch Developers have contributed to the test
system, which is now acknowledged with a constant string in some
of the test files.
The README file in test directory instructed new files contain a
copyright notice, but that has never been done (and it is also not
needed). To simplify things a bit (and lessen confusion) this
instruction is now removed.
As a side enchangement, all of the 3 entries in the whole source
tree cd'ing to `dirname` of "$0" now uses syntax cd "$(dirname "$0")".
This makes these particular lines work when current working directory
is e.g. /c/Program Files/notmuch/test/.
(Probably it would fail elsewhere, though.)
This binding is similar to mutt's, which is
bind {mode} b "bounce-message" # remail a message to another user
where {mode} is 'index', 'pager' or 'attach'.
The new function notmuch-show-message-resend re-sends
message to new recipients using #'message-resend.
Recipients are read from minibuffer as a comma-separated
string (with some keyboard support including tab completion).
Final confirmation before sending is asked.
In case of notmuch reply and notmuch show --part=N it is required that
search terms match to one message. If match count was != 1, error
message "Error: search term did not match precisely one message"
was too vague to explain what happened.
By appending (matched <num> messages) to the error message it
makes the problem more understandable (e.g when <num> is '0'
user reckons the query had a typo in it).
By combining the common parts of CONFIGURE_CFLAGS and CONFIGURE_CXXFLAGS
to a separate make variable and using that as part of their
definitions makes setting of these easier, DRYer and less error prone
(especially as we cannot check potential typing errors there).
