[DO NOT MERGE] shrink test binaries - #6152
Conversation
DWARF is ~80% of every test binary. -gz stores the .debug_* sections compressed (SHF_COMPRESSED/zlib); gdb decompresses them transparently, so debugging is unchanged -- no separate symbol file, no extra step.
Each unit test linked libproxysql.a with --whole-archive, so every binary embedded the entire library and its debug information. Build the archive once as a shared object and link the unit tests against it instead, which removes that duplication without changing what any test does. The .so is staged into $(TAP_LDIR), where every unit test's rpath already points, and depends on the archive so it can never be staler than it. Tests using -Wl,--wrap must keep the static link: --wrap only rewrites references the linker resolves in that link, so it cannot reach inside the .so and the wrapper is silently never called. The makefile now fails the build if a --wrap target is missing from that list. TAP tests, the shipped proxysql binary and macOS are unchanged.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Guard the staged cleanup on non-Darwin builds.
When UNAME_S=Darwin, STAGED_LIBPROXYSQLSO and LIBPROXYSQLSO are empty. This expands $(STAGED_LIBPROXYSQLSO).tmp to .tmp, so make clean can remove an unrelated test/tap/tests/unit/.tmp file. Put this cleanup command inside the existing non-Darwin conditional.

What this does
Three build-system changes that cut the disk footprint of the test suite.
Two files touched, both test Makefiles. No test sources and no ProxySQL sources
change.
236c7db535424e68f3-gz90ea3d13elibproxysql.soThe cause was duplication, not code. On one unit test binary, DWARF was 95 MB of
123 MB (77%);
.textwas 11.5 MB (9%). The same library and the same debuginformation were copied into every binary.
Space saved
Per binary, measured:
Aggregates -- built and counted, not extrapolated:
PROXYSQL40Projected across the full suite (per-binary figures x test count):
15.66 GB -> 2.11 GB (-87%).
CI-unit-tests-asan-coverage.ymlbuilds all 103 unit tests withWITHASAN=1 WITHGCOV=1at 163.1 MB each: ~16.8 GB -> ~1.6 GB.Cost: one new artifact,
lib/libproxysql.so(~50 MB plain, ~160 MBinstrumented). Net saving ~4.8 GB on the unit tests alone. Link time for a unit
test drops from 7.74s to 2.65s.
Evidence
re2. Every test binary carried a private copy of re2 and loaded
libre2.soat runtime. After: 914 re2 symbols compiled in -> 0, stillexactly one
libre2loaded at runtime.-gz. Debug sections now carrySHF_COMPRESSED; gdb reads themtransparently (
info line mainstill resolves to source).Shared libproxysql. Full runs, static vs shared, comparing per-test exit
code and assertion counts
Summary by cubic
Shrinks the test suite's disk footprint with three build-system changes in the TAP and unit test Makefiles:
re2now links dynamically, debug sections compress with-gz, and unit tests on Linux/FreeBSD link a sharedlibproxysql.soinstead of embedding the archive. No test or ProxySQL source changes.Impact
-Wl,--wrapmust keep the static link because--wrapcan't reach inside the shared library; the Makefile fails the build if one is missing from that list.Written for commit c92ff14. Summary will update on new commits.
