While adding the documentation here for add_email_corpus I noticed
that the other email-adding functions in test-lib.sh were not yet
documented here, so add all of that documentation.
When the NOTMUCH variable was originally invented it was used as an
explicit path to the notmuch binary being tested. Today, the test
suite sets the PATH variable instead, so the NOTMUCH variable always
has a value of simply "notmuch".
We simplifying that by using the constant value rather than the
continual variable reference.
Thanks to the new git-based test suite, it's easy to run the whole
test suite in valgrind, (simply "make test OPTIONS="--valgrind"), and
doing so showed this obvious use-after-free bug, (triggered by the
thread-order tests).
A bug in the results-aggregation code was causing the test suite to report
"all tests passed" even when there were failures, (as long as there were
also no "broken" tests). Fix this.
Now that we can usefully pass section names via the NOTMUCH_SKIP_TESTS
environment variable, it's useful to actually print those names out
for the user. Then, since we're now printing these names, let's use
nicer names, (not excessively long but also not using abbreviations
like "msg").
In order for --valgrind to be useful, we drop noisy additional output of
all of the commands being executed in verbose mode. This makes --verbose
alone quite useless, so we don't document it any more.
Also, add a zlib valgrind suppression that was showing up frequently in the
test suite.
This file was obviously describing the git test suite previously, and
would have been very hard to understand in the context of the notmuch
test suite. HOpefully it's easier to follow now.
By scanning test-lib.sh for occurrences of "git" or "GIT", I found
that most of those are internal things, (like the GIT_TEST_TEE_STARTED
variable). But GIT_SKIP_TESTS is part of the user-interface to the
test suite, so we rename it to reference notmuch rather than git.
Also, the GIT_TRACE warning is git-specific, so we drop that as well.
Since we are now using an explicit list of tests to run in
notmuch-test we need to be careful that we don't add a new file of
tests and then forget to add it to the list.
The numbers were meaningless, and they made it hard to find a file of interest.
Instead, we get the ordering we want by adding an explicit list of
tests to run to the notmuch-test script.
These were interfering with the aggregate statistics reported at the
end of the test-suite run. (Always reporting 1 broken, 1 fixed, and 1
skipped). The correct way to test the test-suite itself would be to
run the test suite externally for these cases, capture the expected
result, and then report that as a PASS test.
But, really, there's almost no value in these tests anyway. It's
almost to the level of testing that 'if false; exit 1; fi' returns
1. That is, there are so many ways that the test suite could be broken
internally, that these minor tests don't really help.
The original git test suite works by concatenating many commands into
a very long string (each separated by &&). This is painful to work
with since it prevents the editor from helping by parsing the shell
script, indenting, colorizing, etc.
Instead, we switch this back to something like the original notmuch
test suite, and add two new functions to test-lib.sh
(test_begin_subtest and test_expect_equal) to support these.
This also fixes the test suite to once again display the diff when a
test fails to generate the expected input.
This makes the new, git-derived test suite report results in a manner
similar to the original notmuch test suite.
Notable changes include:
* No more initial '*' on every line
* Only colorize a single word
* Don't print useless test numbers
* Use "PASS" in place of "ok"
* Begin sentences with a capital letter
* Print test descriptions for each block
* Separate each block of tests with a blank line
* Don't summarize counts between each block
This avoids "make test" emitting messages from three (3!) recursive
invocations of make. We change the invocations of the tests themselves
to occur directly from the shell script rather than having the shell
script invoke make again and using wildcards in the Makefile.
In order to have repeatable test suite, all times in messages are set
to UTC time zone to match the time zone (TZ variable) set in
test-lib.sh.

The changes are:
- The notmuch-test was split into several files (t000?-*.sh).
- Removed helper functions which were moved to test-lib.sh
- Replaced every printf with test_expect_success.
- Test commands chained with && (test-lib.sh doesn't use "set -e" in
order to complete the test suite even if something fails)
- Many variables such as ${MAIL_DIR} were properly quoted as they
contain spaces.
- Changed quoting patterns in add_message and generate_message (single
quotes are already used by the test framework).
- ${TEST_DIR} replaced by ${PWD}
QUICK HOWTO:
To run the whole test suite
make
To run only a single test
./t0001-new.sh
To stop on the first error
./t0001-new.sh -i
then mail store and database can be inspected in
"trash directory.t0001-new"
To see the output of tests
./t0001-new.sh -v
To not remove trash directory at the end:
./t0001-new.sh -d
To run all tests verbosely:
make GIT_TEST_OPTS="-v"

Modify the helper functions to work with git-based test suite i.e.
1) Quote arguments where it is necessary.
2) Do not use $NOTMUCH. It is equal to "notmuch" since $PATH is set to
the build tree.
3) Modify pass_if_equal to fit into the git-based test suite.

This removes Git specific things from the test-lib.sh and adds helper
functions for notmuch taken from Carl's notmuch-test script. README is
also slightly modified to reflect the current state.

Git uses a simple and yet powerful test framework, written in shell.
The framework is easy to use for both users and developers so I think
it would help if it is used in notmuch as well.
This is a copy of Git's test framework from commit
b6b0afdc30e066788592ca07c9a6c6936c68cc11 in git repository.

We extend the '|' command so that passing a prefix argument, (for
example, "C-u |"), causes it to pipe all open messages in the current
thread rather than just the single, current message.
This was previously wrapped for unsubtituted command names. It looks
much better in the notmuch-help (available with '?') if wrapped
according to the length of the substituted command names.
Since commit f41a35e292 running a command
such as:
NOTMUCH_CONFIG=/new/config/file notmuch setup
would result in a segmentation fault.
The purpose of that commit was to ensure that an attempt to manipulate
a non-standard database would not inadvertently manipulate the default
database only due to a typo in the NOTMUCH_CONFIG environment
variable. That is, a command like:
NOTMUCH_CONFIG=mistyped-config-filename notmuch tag -new tag:new
shouldn't modify the database at ${HOME}/mail, but should instead
simply report that the mistype configuration filename does not exist.
We fix both cases simultaneously by reporting the error message
whenever the function calling notmuch_config_open is not explicitly
prepared for a default configuration file.
We don't love the mbox format, but it's still sometimes the most
practical way to share a collection of messages as a single file.
Here we implement the "mboxrd" variant of the mbox file format. This
variant applies reversible escaping by prefixing a '>' character to
all lines in the email messages matching the regular expression:
"^>*From "
This allows the escaping to be reliably removed. A reader should remove
a '>' from any line matching the regular expression:
"^>>*From "
More details on the mboxrd formats (and others as well) can be found
here:

Let the user destroy objects that she wants explicitly.
It's not possible to specify the order objects are garbage collected.

Micah Anderson reported an issue where a message failed to display in
the emacs interface, (it instead gave an error, "json-read-string: Bad
string format").
Micah tracked this down to the json output from "notmuch show" being
interrupted by a GMime error message:
gmime-CRITICAL **: g_mime_stream_filter_add: assertion
`GMIME_IS_FILTER (filter)
I tracked this down further to notmuch passing a NULL value to
g_mime_stream_filter_add. And this was due to calling
g_mime_filter_charset_new with a value of "unknown-8bit".
So we add a test message withe a Conten-Type of "text/plain;
charset=unknown-8bit" from Micah's message. Then we fix "notmuch show"
to test for NULL before calling g_mime_stream_filter_add. Bug fixed.
Various users were confused as to why they couldn't run notmuch
immediately after "make install", (with linker errors saying that
libnotmuch.so could not be found). The errors came from two different
causes:
1. The user had installed to a system library directory, but had not
yet run ldconfig.
2. The user had installed to some non-system directory, and had not
set the LD_LIBRARY_PATH variable.
With this change we fix both problems (on Linux) without the user
having to do anything additional. We first use ldconfig to find the
system library directories. If the user is installing to one of these,
then we run ldconfig as part of "make install".
For case (2) we use the -rpath and --enable-new-dtags linker options
to install a DT_RUNPATH entry in the binary. This entry tells the
dynamic linker where to find libnotmuch. Without the
--enable-new-dtags option only a DT_RPATH option would be installed,
(which has the drawback of not allowing any override with the
LD_LIBRARY_PATH variable).
Distributions (such as Debian and Fedora) don't want to see binaries
packaged with a DT_RPATH or DT_RUNPATH entry. This should be avoided
automatically as long as the packages install to standard locations,
(such as /usr/lib).
The idea here is to more easily support filenames with spaces in them
in various loops. We're about to add a loop over the paths configured
by the dynamic linker. Hopefully, they wouldn't contain spaces, but
one never knows so we might as well be prepared.
Scott Henson reported an internal error that occurred when he tried to
add a message that referenced another message with a message ID well
over 300 characters in length. The bug here was running into a Xapian
limit for the length of metadata key names, (which is even more
restrictive than the Xapian limit for the length of terms).
We fix this by noticing long message ID values and instead using a
message ID of the form "notmuch-sha1-<sha1_sum_of_message_id>". That
is, we use SHA1 to generate a compressed, (but still unique), version
of the message ID.
We add support to the test suite to exercise this fix. The tests add a
message referencing the long message ID, then add the message with the
long message ID, then finally add another message referencing the long
ID. Each of these tests exercise different code paths where the
special handling is implemented.
A final test ensures that all three messages are stitched together
into a single thread---guaranteeing that the three code paths all act
consistently.
We're about to add a test with an excessively long message-id, (512
characters or so). This exceeds filename length limits, so just always
the simple counter to generate the filenames, (which we were doing for
messages with non-custom IDs anyway).
Previously we were using Xapian's add_document to allocate document ID
values for notmuch_message_t objects. This had the drawback of adding
a partially constructed mail document to the database. If notmuch was
subsequently interrupted before fully populating this document, then
later runs would be quite confused when seeing the partial documents.
There are reports from the wild of people hitting internal errors of
the form "Message ... has no thread ID" for example, (which is
currently an unrecoverable error).
We fix this by manually allocating document IDs without adding
documents. With this change, we never call Xapian's add_document
method, but only replace_document with either the current document ID
of a message or a new one that we have allocated.
