support: Add FUSE-based file system test framework to support/

2024-09-05T10:05:32Z

This allows to monitor the exact file system operations performed by glibc and inject errors. Hurd does not have . To get the sources to compile at least, the same approach as in support/test-container.c is used. Reviewed-by: DJ Delorie

support: Add

2024-09-05T10:05:32Z

Use static functions for readdir/readdir_r, so that -D_FILE_OFFSET_BITS=64 does not improperly redirect calls to the wrong implementation. Reviewed-by: DJ Delorie

Bundle userspace header from Linux 6.10

2024-09-05T09:34:31Z

And include the required licensing information. The only change is a removed trailing empty line in LICENSES/exceptions/Linux-syscall-note. Bundling is the recommended way to deal with the evolution of the FUSE userspace interface because structs change sizes over time. The kernel maintains compatibility, but source-level compatibility on recompilation may require additional code that is aware of older struct sizes.

Add support/ code for checking file contents

2024-09-03T13:53:01Z

For use in freopen tests, add various support/ helper interfaces for use in checking file contents. Tested for x86_64.

support: Report errno constants in TEST_COMPARE failures

2024-08-26T14:46:45Z

If the expression is errno, decode it as an errno constant using strerrorname_np. Reviewed-by: Arjun Shankar

support: Use macros for *stat wrappers

2024-08-16T14:05:20Z

Macros will automatically use the correct types, without having to fiddle with internal glibc macros. It's also impossible to get the types wrong due to aliasing because support_check_stat_fd and support_check_stat_path do not depend on the struct stat* types. The changes reveal some inconsistencies in tests. Reviewed-by: Adhemerval Zanella

support: Include for strcmp in support_format_addrinfo.c

2024-08-16T14:05:19Z

This is currently implied by the internal headers, but it makes sense not to rely on this. Reviewed-by: Adhemerval Zanella

support: Remove #include

2024-08-16T14:05:19Z

This is not needed: include/intprops.h has its own detection logic. It makes building these files outside of glibc easer. Reviewed-by: Adhemerval Zanella

support: Add options list terminator to the test driver

2024-08-09T15:01:19Z

This avoids crashes if a test is passed unknown options. Reviewed-by: Adhemerval Zanella
