2020-04-27Make upcasting css::uno::Reference ctor require complete typesStephan Bergmann
The main reason for the "home-grown" UpCast introduced with 904b3d1fceee5827076758ed2a81f80cb73493ca "Up-cast conversion constructor for css::uno::Reference" in 2013 was probably that we could not yet rely on C++11 std::is_base_of back then. A (welcome) side effect was that the derived class could be incomplete. However, specializations of UpCast relying on whether or not T2 is incomplete are obviously an ODR violation if the type is incomplete in some TUs and complete (and derived from T1) in others. And even if UpCast had internal linkage, it would still be brittle that its behavior depends on the completeness of T2 at the point of the template's instantiation, and not necessarily at the point of use. That means we should better base that ctor on std::is_base_of (which we can do now since 39a1edd6fec902ef378acce8af42c4d7fba280d0 "Make css::uno::Reference upcast ctor LIBO_INTERNAL_ONLY"), which causes a compilation error at least on Clang and GCC if the completeness requirements are not met. This change fixes all the cases where types need to be complete now, plus any resulting loplugin:referencecasting warnings ("the source reference is already a subtype of the destination reference").

2020-01-28New loplugin:unsignedcompareStephan Bergmann
"Find explicit casts from signed to unsigned integer in comparison against unsigned integer, where the cast is presumably used to avoid warnings about signed vs. unsigned comparisons, and could thus be replaced with o3tl::make_unsigned for clairty." (compilerplugins/clang/unsignedcompare.cxx) o3tl::make_unsigned requires its argument to be non-negative, and there is a chance that some original code like static_cast<sal_uInt32>(n) >= c used the explicit cast to actually force a (potentially negative) value of sal_Int32 to be interpreted as an unsigned sal_uInt32, rather than using the cast to avoid a false "signed vs. unsigned comparison" warning in a case where n is known to be non-negative. It appears that restricting this plugin to non- equality comparisons (<, >, <=, >=) and excluding equality comparisons (==, !=) is a useful heuristic to avoid such false positives. The only remainging false positive I found was 0288c8ffecff4956a52b9147d441979941e8b87f "Rephrase cast from sal_Int32 to sal_uInt32". But which of course does not mean that there were no further false positivies that I missed. So this commit may accidentally introduce some false hits of the assert in o3tl::make_unsigned. At least, it passed a full (Linux ASan+UBSan --enable-dbgutil) `make check && make screenshot`. It is by design that o3tl::make_unsigned only accepts signed integer parameter types (and is not defined as a nop for unsigned ones), to avoid unnecessary uses which would in general be suspicious. But the STATIC_ARRAY_SELECT macro in include/oox/helper/helper.hxx is used with both signed and unsigned types, so needs a little oox::detail::make_unsigned helper function for now. (The ultimate fix being to get rid of the macro in the first place.)

2019-12-01Introduce o3tl::optional as an alias for std::optionalStephan Bergmann
...with a boost::optional fallback for Xcode < 10 (as std::optional is only available starting with Xcode 10 according to <https://en.cppreference.com/w/cpp/compiler_support>, and our baseline for iOS and macOS is still Xcode 9.3 according to README.md). And mechanically rewrite all code to use o3tl::optional instead of boost::optional. One immediate benefit is that disabling -Wmaybe-uninitialized for GCC as per fed7c3deb3f4ec81f78967c2d7f3c4554398cb9d "Slience bogus -Werror=maybe-uninitialized" should no longer be necessary (and whose check happened to no longer trigger for GCC 10 trunk, even though that compiler would still emit bogus -Wmaybe-uninitialized for uses of boost::optional under --enable-optimized, which made me ponder whether this switch from boost::optional to std::optional would be a useful thing to do; I keep that configure.ac check for now, though, and will only remove it in a follow up commit). Another longer-term benefit is that the code is now already in good shape for an eventual switch to std::optional (a switch we would have done anyway once we no longer need to support Xcode < 10). Only desktop/qa/desktop_lib/test_desktop_lib.cxx heavily uses boost::property_tree::ptree::get_child_optional returning boost::optional, so let it keep using boost::optional for now. After a number of preceding commits have paved the way for this change, this commit is completely mechanical, done with > git ls-files -z | grep -vz -e '^bin/find-unneeded-includes$' -e '^configure.ac$' -e '^desktop/qa/desktop_lib/test_desktop_lib.cxx$' -e '^dictionaries$' -e '^external/' -e '^helpcontent2$' -e '^include/IwyuFilter_include.yaml$' -e '^sc/IwyuFilter_sc.yaml$' -e '^solenv/gdb/boost/optional.py$' -e '^solenv/vs/LibreOffice.natvis$' -e '^translations$' -e '\.svg$' | xargs -0 sed -i -E -e 's|\<boost(/optional)?/optional\.hpp\>|o3tl/optional.hxx|g' -e 's/\<boost(\s*)::(\s*)(make_)?optional\>/o3tl\1::\2\3optional/g' -e 's/\<boost(\s*)::(\s*)none\>/o3tl\1::\2nullopt/g' (before committing include/o3tl/optional.hxx, and relying on some GNU features). It excludes some files where mention of boost::optional et al should apparently not be changed (and the sub-repo directory stubs). It turned out that all uses of boost::none across the code base were in combination with boost::optional, so had all to be rewritten as o3tl::nullopt.
