Add a smoke testing tool to support testing the date/time parser
module directly and independent of the rest of notmuch.
Credits to Michal Sojka <sojkam1@fel.cvut.cz> for the stdin parsing
idea and consequent massive improvement in testability.
On FreeBSD, and probably anywhere else someone installed xapian to
some other prefix, we need to use XAPIAN_LDFLAGS to make the linker can
actually find libxapian.
These extra directories cause problems for building on Debian
twice in a row.
In order to remove directories, we need to us "rm -rf" instead of
"rm -f". So now we should be extra careful what we add to the
variable CLEAN.
binutils-2.22 changes the behaviour of ld by defaulting to
--no-copy-dt-needed-entries, which means that required objects/libs are not
"indirectly" linked through intermediate objects/libs anymore. As a consequence,
when using binutils-2.22, building symbol-test fails with the following error:
/usr/bin/ld: test/symbol-test.o: undefined reference to symbol
'std::basic_string<char, std::char_traits<char>, std::allocator<char>
>::~basic_string()@@GLIBCXX_3.4'
/usr/bin/ld: note: 'std::basic_string<char, std::char_traits<char>,
std::allocator<char> >::~basic_string()@@GLIBCXX_3.4' is defined in DSO
/usr/lib/libstdc++.so.6 so try adding it to the linker command line
/usr/lib/libstdc++.so.6: could not read symbols: Invalid operation
An easy fix is to link using CXX instead of CC.
If symbol-test is built in symbol-hiding with hardcoded g++ invokation,
it's not so easy to pass $(srcdir) which is required to find notmuch.h
when srcdir and builddir are separate directories.
The compilation of the smtp-dummy program would fail if a build was
attempted on a system without getline. Fix this by simply including
the existing notmuch_compat_srcs variable when constructing the list
of source files for compiling smtp-dummy.
Rather than *reall* sending mail here, we instead have a new test
program, smtp-dummy which implements (a small piece of) the
server-side SMTP protocol and saves a mail message to the filename
provided. This gives us reasonable test coverage of a large chunk of
the notmuch+emacs code base (down to talking to an SMTP server with
the final mail contents).
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.
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.
