We put some effort into testing the built copy rather than some
installed copy. On the other hand for people like packagers, testing
the installed copy is also of interest.
When NOTMUCH_TEST_INSTALLED is set to a nonempty value, tests do not
require a built notmuch tree or running configure.
Some of the tests marked as broken when running against installed
notmuch are probably fixable.
readelf on (at least) ppc64le sometimes generates some extension to
the Ndx name inside '[]'. Remove this output to allow our simple
column based parsing to work.
It turns out that using nm -P isn't as portable as hoped. In
particular with some ELF ABIs (e.g. ppc64 ELFv1), the desired symbols
end up in the data section instead of text.
The test is currently only functional on ELF based architectures, so I
think it's legit to depend on readelf instead of nm.
The switch to readelf has the advantage that we can explicitely ask
for all of the symbols with global visibility, rather than grepping
for notmuch. That seems a more robust approach since it will catch any
strangely named global symbols.
Inspired by the suggestion of
id:20200727154108.16269-3-congdanhqx@gmail.com
to drop the configuration test for the default backend. This version
is hopefully robust against backend changes.
The dynamic generation of the linker version script for libnotmuch
exports has grown rather complicated.
Reverse the visibility control by hiding symbols by default using
-fvisibility=hidden, and explicitly exporting symbols in notmuch.h
using #pragma GCC visibility. (We could also use __attribute__
((visibility ("default"))) for each exported function, but the pragma
is more convenient.)
The above is not quite enough alone, as it would "leak" a number of
weak symbols from Xapian and C++ standard library. Combine it with a
small static version script that filters out everything except the
notmuch_* symbols that we explicitly exposed, and the C++ RTTI
typeinfo symbols for exception handling.
Finally, as the symbol hiding test can no longer look at the generated
symbol table, switch the test to parse the functions from notmuch.h.
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.
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.
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.
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.
There are many places in the notmuch code where the path is assumed to be absolute. If someone (TM) wants a project, one could remove these assumptions. In the mean time, prevent users from shooting themselves in the foot.
Update test suite mark tests for this error as no longer broken, and
also convert some tests that used relative paths for nonexistent
directories.
After yet another variation in objdump output caused this test to fail
(on a Debian port, no less), I decided whatever putative benefit we
get from looking at the object files instead of the library isn't
worth the maintenence headache.
This version uses nm -P. nm -P should be portable, and fixed format.
It purposely doesn't use the -D argument, since that is non-POSIX and
nm on GNU/Linux seems do the right thing without it.
It still won't work out of the box on e.g. Mac OS/X. I think the right
thing to do there is to move some more configuration information into
sh.config.
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.
