Fri May 17 16:25:49 MSK 2019
Made fixes:
- Added CMAKE_EXTRA_PARAMS environment to docker's container
runs to enable -DENABLE_LTO=ON/OFF cmake option.
- Added CC/CXX environment to docker's container runs to set
clang for cmake. Also the additional environment variables
{CC,CXX}_FOR_BUILD were not postponed, because we didn't
run cross-compilation at the moment, for more info check:
https://docs.travis-ci.com/user/languages/cpp/#choosing-compilers-to-test-against
- Changed LTO docker's image to 'debian-buster' due to LTO needed
higher versions of packages, check for more information commit:
f9e28ce4602aff3f9bb4e743b0d6167b0f8df88d ('Add LTO support')
- Fixed sources to avoid of failures on builds by GCC with LTO:
1) src/box/memtx_rtree.c: In function ‘mp_decode_rect’:
src/box/memtx_rtree.c:86:24: error: ‘c’ may be used uninitialized
in this function [-Werror=maybe-uninitialized]

2) src/box/sql/func.c: In function ‘quoteFunc’:

declared with attribute warning: curl_easy_setopt expects a long
argument for this option [-Werror]

^
5) src/lua/httpc.c: In function ‘luaT_httpc_request’:
src/lua/httpc.c:128:64: error: ‘MEM[(int *)&parser + 20B]’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]

^
src/lua/httpc.c:67:21: note: ‘MEM[(int *)&parser + 20B]’ was declared here
struct http_parser parser;
