From 6cf3345297d371b4785d80d54e802b52ff09e8c2 Mon Sep 17 00:00:00 2001 From: fanquake Date: Wed, 7 Jul 2021 19:59:31 +0800 Subject: [PATCH] scripts: adjust test-symbol-check for guix release environment Now that our release binaries are build in a glibc 2.24 and 2.27 environment, we can't use a symbol from glibc 2.28 to test our checks. Replace renameat2() with nextup(), which was introduced in 2.24. Note that this also means re-disabling the test for RISC-V, however RISC-V is built in a glibc 2.27 environment, and our minimum required glibc for that binary is 2.27. --- contrib/devtools/test-symbol-check.py | 25 ++++++++++++++++--------- 1 file changed, 16 insertions(+), 9 deletions(-) diff --git a/contrib/devtools/test-symbol-check.py b/contrib/devtools/test-symbol-check.py index 68e479009b..7d83c5f751 100755 --- a/contrib/devtools/test-symbol-check.py +++ b/contrib/devtools/test-symbol-check.py @@ -19,32 +19,39 @@ def call_symbol_check(cc: List[str], source, executable, options): os.remove(executable) return (p.returncode, p.stdout.rstrip()) +def get_machine(cc: List[str]): + p = subprocess.run([*cc,'-dumpmachine'], stdout=subprocess.PIPE, universal_newlines=True) + return p.stdout.rstrip() + class TestSymbolChecks(unittest.TestCase): def test_ELF(self): source = 'test1.c' executable = 'test1' cc = determine_wellknown_cmd('CC', 'gcc') - # renameat2 was introduced in GLIBC 2.28, so is newer than the upper limit - # of glibc for all platforms + # there's no way to do this test for RISC-V at the moment; we build for + # RISC-V in a glibc 2.27 envinonment and we allow all symbols from 2.27. + if 'riscv' in get_machine(cc): + self.skipTest("test not available for RISC-V") + + # nextup was introduced in GLIBC 2.24, so is newer than our supported + # glibc (2.17), and available in our release build environment (2.24). with open(source, 'w', encoding="utf8") as f: f.write(''' #define _GNU_SOURCE - #include - #include + #include - int renameat2(int olddirfd, const char *oldpath, - int newdirfd, const char *newpath, unsigned int flags); + double nextup(double x); int main() { - renameat2(0, "test", 0, "test_", RENAME_EXCHANGE); + nextup(3.14); return 0; } ''') - self.assertEqual(call_symbol_check(cc, source, executable, []), - (1, executable + ': symbol renameat2 from unsupported version GLIBC_2.28\n' + + self.assertEqual(call_symbol_check(cc, source, executable, ['-lm']), + (1, executable + ': symbol nextup from unsupported version GLIBC_2.24\n' + executable + ': failed IMPORTED_SYMBOLS')) # -lutil is part of the libc6 package so a safe bet that it's installed
