| | | | | | | | * tests/test-regex.c (tests): Remove the comment saying that some tests are not used. That comment was copied along with tests from glibc where some of these tests are commented out. Fixes: 70b673eb7 ("regex: fix longstanding backref match bug")
* Generate correct license notices in libunistring files.Bruno Haible2021-06-045-0/+80
| | | | | | | | | | | | | | | | | | | * lib/gen-uni-tables.c (output_library_license, output_tests_license): New functions. (output_predicate, output_category, output_combclass, output_bidi_category, output_decimal_digit, output_digit, output_numeric, output_mirror, output_joining_type, output_joining_group, output_scripts, output_scripts_byname, output_blocks, output_ident_category, output_lbrk_tables, output_wbrk_tables, output_gbp_table, output_decomposition_tables, output_composition_tables, output_simple_mapping, output_casing_rules): Invoke output_library_license.

* reallocarray-tests: port to weird platformsPaul Eggert2021-05-301-3/+6
| | | | | | * tests/test-reallocarray.c (main): Don’t assume that PTRDIFF_MAX / 2 + 1 <= SIZE_MAX. POSIX allows platforms where this isn’t true, though I don’t know of any examples.
* dfa, etc.: prefer xreallocarray to older namePaul Eggert2021-05-301-4/+4
| | | | | | | | | * lib/dfa.c (addtok_mb, realloc_trans_if_necessary, enlist): * lib/readtokens.c (readtokens): * tests/uninorm/test-u32-normalize-big.c: (read_normalization_test_file): Prefer xreallocarray to the equivalent xnrealloc. The newer name follows the glibc lead of ‘reallocarray’.
* sigsegv: don’t assume SIGSTKSZ is a constantPaul Eggert2021-05-213-9/+15
| | | | | | | | | | | | * m4/sigaltstack.m4 (SV_SIGALTSTACK): Don’t attempt to override SIGSTKSZ. Instead, use an array that is plenty large, while checking that it’s large enough. Also, be consistent about putting that array in static storage rather than on the stack. * tests/altstack-util.h (SIGSTKSZ): Don’t define. (MYSTACK_SIZE): New macro, used consistently instead of SIGSTKSZ. (mystack_storage, mystack): Now static. (prepare_alternate_stack) [defined SIGSTKSZ]: Check that MYSTACK_SIZE is large enough.
* sigsegv: Add tests.Bruno Haible2021-05-166-0/+792
| | | | | | | | | | | * tests/test-sigsegv-catch-segv1.c: New file, from GNU libsigsegv with modifications. * tests/test-sigsegv-catch-segv2.c: Likewise. * tests/test-sigsegv-catch-stackoverflow1.c: Likewise. * tests/test-sigsegv-catch-stackoverflow2.c: Likewise. * tests/altstack-util.h: Likewise. * tests/mmap-anon-util.h: Likewise. * modules/sigsegv-tests: New file.
* realloc-gnu: avoid glibc MALLOC_CHECK_ issuePádraig Brady2021-05-151-1/+4
| | | | | | | | * tests/test-realloc-gnu.c (main): if MALLOC_CHECK_ env var is set then don't check ENOMEM is returned from realloc(). See https://sourceware.org/bugzilla/show_bug.cgi?id=27870 Note it doesn't suffice to unsetenv() this var within the program, as the hooks have already been set up at that stage.
* fcntl tests: Avoid failure in MacPorts.Bruno Haible2021-05-142-1/+12
| | | | | | | | | Reported by Nicholas Gaya <nicholasgaya@gmail.com> in <https://lists.gnu.org/archive/html/bug-gnulib/2021-05/msg00014.html>. * tests/test-fcntl.c (main): Close fd 10 before assuming that it is closed. * tests/test-execute-main.c: Update comment.

(main): Use ASSERT. * tests/test-realloc-gnu.c: Include "macros.h". (main): Use ASSERT. * tests/test-reallocarray.c: Include "macros.h". (main): Use ASSERT. * modules/malloc-gnu-tests (Files): Add tests/macros.h. * modules/calloc-gnu-tests (Files): Likewise. * modules/realloc-gnu-tests (Files): Likewise. * modules/reallocarray-tests (Files): Likewise.

* free tests: Avoid test failure on glibc < 2.15.Bruno Haible2021-05-091-1/+3
| | | | * tests/test-free.c (main): Skip the hairy test on glibc < 2.15.
* reallocarray: don’t crash if item size is 0Paul Eggert2021-04-251-2/+7
| | | | | | | | | This problem affects only platforms where xalloc_oversized divides a number by the size arg. Fix this by defining xalloc_oversized (n, s) to work even if s == 0. * lib/malloca.h, lib/xalloc-oversized.h: Document new behavior. * lib/xalloc-oversized.h (__xalloc_oversized): Do not crash if S==0. * tests/test-reallocarray.c (main): Test for the bug.

* execute-tests: pacify compilerPaul Eggert2021-04-211-3/+3
| | | | | | * tests/test-execute-main.c (main): Use 0x7DEADBEE rather than 0xDEADBEEF for nonces, to avoid provoking AIX XLC compiler warning that the latter is out of int range.
* malloc-gnu-tests, etc.: use volatile for clangPaul Eggert2021-04-207-17/+20
| | | | | | | | | | | | | | | In some more test locations, store the result of malloc etc. into a volatile pointer so that clang doesn’t optimize away the malloc and thus bypass the test. This fixes a malloc-gnu test failure on macOS 11.2.3 with clang 12.0.0 on ARM. * tests/test-alloca-opt.c (do_allocation): * tests/test-malloc-gnu.c (main): * tests/test-malloca.c (do_allocation): * tests/test-realloc-gnu.c (main): * tests/test-reallocarray.c (main): * tests/test-aligned-malloc.c (main): * tests/test-aligned_alloc.c (main): Store malloc etc. results into a volatile pointer.
