From 6f0a78a62fc201bc97a5e82ea531c07e5e8e6d21 Mon Sep 17 00:00:00 2001 From: shamb0 Date: Tue, 3 Dec 2024 11:24:44 +0530 Subject: [PATCH] tests: Add architecture-specific tests for 32/64-bit systems - Use timestamp 1893456000 (2030-01-01) for 32-bit systems to stay within i32 range - Use timestamp 2524608000 (2050-01-01) for 64-bit systems - Add conditional compilation flags to select appropriate tests per architecture - Add compile-time verification for 32-bit timestamp bounds Signed-off-by: shamb0 --- tests/pass-dep/libc/libc-time.rs | 57 +++++++++++++++++++++++++++++--- 1 file changed, 53 insertions(+), 4 deletions(-) diff --git a/tests/pass-dep/libc/libc-time.rs b/tests/pass-dep/libc/libc-time.rs index f17812118f..032f2124c7 100644 --- a/tests/pass-dep/libc/libc-time.rs +++ b/tests/pass-dep/libc/libc-time.rs @@ -8,7 +8,11 @@ fn main() { test_localtime_r_gmt(); test_localtime_r_pst(); test_localtime_r_epoch(); - test_localtime_r_future(); + // Architecture-specific tests + #[cfg(target_pointer_width = "32")] + test_localtime_r_future_32b(); + #[cfg(target_pointer_width = "64")] + test_localtime_r_future_64b(); } /// Tests whether clock support exists at all @@ -192,10 +196,14 @@ fn test_localtime_r_epoch() { } // Future date test (testing large values) -fn test_localtime_r_future() { +#[cfg(target_pointer_width = "64")] +fn test_localtime_r_future_64b() { let key = "TZ"; env::set_var(key, "GMT"); - const TIME_SINCE_EPOCH: libc::time_t = 2524608000; // 2050-01-01 00:00:00 + + // Using 2050-01-01 00:00:00 for 64-bit systems + // value that's safe for 64-bit time_t + const TIME_SINCE_EPOCH: libc::time_t = 2524608000; let custom_time_ptr = &TIME_SINCE_EPOCH; let mut tm = create_empty_tm(); @@ -206,7 +214,7 @@ fn test_localtime_r_future() { assert_eq!(tm.tm_hour, 0); assert_eq!(tm.tm_mday, 1); assert_eq!(tm.tm_mon, 0); - assert_eq!(tm.tm_year, 150); + assert_eq!(tm.tm_year, 150); // 2050 - 1900 assert_eq!(tm.tm_wday, 6); // Saturday assert_eq!(tm.tm_yday, 0); assert_eq!(tm.tm_isdst, -1); @@ -227,3 +235,44 @@ fn test_localtime_r_future() { assert!(ptr::eq(res, &mut tm)); env::remove_var(key); } + +#[cfg(target_pointer_width = "32")] +fn test_localtime_r_future_32b() { + let key = "TZ"; + env::set_var(key, "GMT"); + + // Using 2030-01-01 00:00:00 for 32-bit systems + // Safe value within i32 range + const TIME_SINCE_EPOCH: libc::time_t = 1893456000; + let custom_time_ptr = &TIME_SINCE_EPOCH; + let mut tm = create_empty_tm(); + + let res = unsafe { libc::localtime_r(custom_time_ptr, &mut tm) }; + + // Verify 2030-01-01 00:00:00 + assert_eq!(tm.tm_sec, 0); + assert_eq!(tm.tm_min, 0); + assert_eq!(tm.tm_hour, 0); + assert_eq!(tm.tm_mday, 1); + assert_eq!(tm.tm_mon, 0); + assert_eq!(tm.tm_year, 130); // 2030 - 1900 + assert_eq!(tm.tm_wday, 2); // Tuesday + assert_eq!(tm.tm_yday, 0); + assert_eq!(tm.tm_isdst, -1); + + #[cfg(any( + target_os = "linux", + target_os = "macos", + target_os = "freebsd", + target_os = "android" + ))] + { + assert_eq!(tm.tm_gmtoff, 0); + unsafe { + assert_eq!(std::ffi::CStr::from_ptr(tm.tm_zone).to_str().unwrap(), "+00"); + } + } + + assert!(ptr::eq(res, &mut tm)); + env::remove_var(key); +}
