On some system configurations, setting a breakpoint on the "add_file"
function then issuing "continue" in gdb causes the debugger to
seemingly jump over the add_file invocation. This results in a test
failure, as the "Handle files vanishing between scandir and add_file"
subtest expects add_file to be called and fail due to the vanishing
file. The compiler optimization level also plays a role - the problem
can be reproduced with CFLAGS having -O2 but not -Og.
This problem was observed manifesting as a test failure on Travis CI
configured with "dist: trusty" and "sudo: false". It was not
reproducible on a local Docker image of Travis' runtime environment,
so Travis' virtualization infrastructure likely plays a role as well.
* T050-new.sh: Breakpoint notmuch_database_add_message instead of
add_file to the same effect, and avoid bad gdb behaviour on Travis
CI.
Amended by db:
s/notmuch_database_add_message/notmuch_database_index_file/
Somehow the wrapper function doesn't work as a breakpoint; perhaps due
to inlining.
Unify the subtests by requiring test_begin_subtest before
test_expect_code. (Similar change for test_expect_success has already
been done.)
This increases clarity in the test scripts by having a separate line
for the start of the subtest with the heading, and makes it possible
to simplify the test infrastructure by making all subtests similar.
The code to skip multiple slashes in _notmuch_database_split_path()
skips back one character too much. This is compensated by a +1 in the
length parameter to the strndup() call. Mostly this works fine, but if
the path is to a file under a top level directory with one character
long name, the directory part is mistaken to be part of the file name
(slash == path in code). The returned directory name will be the empty
string and the basename will be the full path, breaking the indexing
logic in notmuch new.
Fix the multiple slash skipping to keep the slash variable pointing at
the last slash, and adjust strndup() accordingly.

database: Store the parent ID for each directory document.
just a little over two months after the initial commit in the Notmuch
code history, making this the longest living bug in Notmuch to date.
In several places in the test suite we intentionally corrupt the Xapian
database in order to test error handling. This corruption is specific to
the on-disk organization of the database, and that changed with the
glass backend. We use the previously computed default backend to make
the tests adapt to changing names.
There was a problem with the directory documents being left behind when
the filesystem directory was removed. This was worked around in [1].
However, that ignored the fact that the directory documents are also
still listed by notmuch_directory_get_child_directories() leading to
confusing results when running notmuch new. The directory documents are
found and queued for removal over and over again.
Fix the problem for real by removing the directory documents. This fixes
the tests flagged as broken in [2].
The (non-deterministic) hack test from [3] also still passes with this
change.

Drop the test update added in [1] and mark the test as broken, like the
tests flagged as broken in [2]. These all reflect the same underlying
breakage with (lack of) directory deletion.
[1] commit e4e04bbc32
[2] commit ed9ceda623
The files (test) scripts source (with builtin command `.`) provides
information which the scripts depend, and without the `source` to
succeed allowing script to continue may lead to dangerous situations
(e.g. rm -rf "${undefined_variable}"/*).
At the end of all source (.) lines construct ' || exit 1' was added;
In our case the script script will exit if it cannot find (or read) the
file to be sourced. Additionally script would also exits if the last
command of the sourced file exited nonzero.
I marked the tests where I really couldn't understand the output as
broken. It could also be that I don't understand how directory removal
is supposed to work.
Try to narrow down what part of the code adds files and directories to
the queue(s) to be deleted.
Update one test. The output is slightly confusing, but I believe it is
correct, resulting from a directory being discovered but containing only ignored files.
This is arguably testing the same thing twice, but in the brave new
future where we don't use printf anymore, each subcommand will be
responsible for handling the output on it's own.
We generally do not support mbox files, but for historical reasons
we've supported single-message mbox files, with a deprecation
message. We've tried dropping the support altogether, but backed out
of it because we'd need to stop indexing them, while keeping support
for previously indexed files. This would be more complicated than
simply supporting single-message mbox files. Therefore, drop the
deprecation message, and just silently accept single-message mboxes.
This is effectively a revert of

lib: drop support for single-message mbox files
The intention was to drop support for indexing new single-message mbox
files (and whether that was a good idea in the first place is
arguable). However this inadvertently broke support for reading
headers from previously indexed single-message mbox files, which is
far worse.
Distinguishing between the two cases would require more code than
simply bringing back support for single-message mbox files.
We've supported mbox files containing a single message for historical
reasons, but the support has been deprecated, with a warning message
while indexing, since Notmuch 0.15. Finally drop the support, and
consider all mbox files non-email.
All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
