34098b669c0cbc024cd08e686891f1dfe0a10aaf: [Backport #21144] [Bug #21144] Win32: Use Windows time zone ID if TZ is not set If the TZ environment variable is not set, the time zone names retrieved from the system are localized for UI display and may vary across editions and language packs for the same time zone. Use the time zone IDs that are invariant across environments instead. [Bug #21144] Win32: Convert the time zone name to the current locale The Windows time zone IDs provided by Microsoft as of 24H1 are ASCII only all, but the API itself is not impossible to set non-ASCII key name. Prefer the current locale encoding for now until we move to UTF-8 including environment variables and command line arguments.

#20327] (#10313) [Bug #20327] Do not count subsecond to calculate UTC offset Assume that there will never be any time zones with UTC offsets that are subseconds. Historically, UTC offset has only been used down to the second.

If we always return 0, we might as well not define the function at all.
2023-11-07Use embedded TypedData for Time objectsPeter Zhu
This drops the total size of a Time object from 86 bytes to 80 bytes. Running the benchmark benchmark/time_now.yml, this commit improves performance of Time.now by about 30%: ``` Time.now Branch: 13159405.4 i/s Master: 10036908.7 i/s - 1.31x slower Time.now(in: "+09:00") Branch: 2712172.6 i/s Master: 2138637.9 i/s - 1.27x slower ``` It also decreases memory usage by about 20%: ``` ary = 10_000_000.times.map { Time.now } puts `ps -o rss= -p #{$$}` ``` Branch: 961792 Master: 1196544 Co-Authored-By: Jean Boussier <byroot@ruby-lang.org>

2023-04-04Fix crash in Time on 32-bit systemsPeter Zhu
[Bug #19575] struct vtm is packed causing it to have a size that is not aligned on 32-bit systems. When allocating it on the stack, it will have unaligned addresses which means that the fields won't be marked by the GC when scanning the stack (since the GC only marks aligned addresses). This can cause crashes when the fields are heap allocated objects like Bignums. This commit moves the flags in struct time_object into struct vtm for space efficiency and removes the need for packing. This is an example of a crash: ruby(rb_print_backtrace+0xd) [0x56848945] ../src/vm_dump.c:785 ruby(rb_vm_bugreport) ../src/vm_dump.c:1101 ruby(rb_assert_failure+0x7a) [0x56671857] ../src/error.c:878 ruby(vm_search_cc+0x0) [0x56666e47] ../src/vm_method.c:1366 ruby(rb_vm_search_method_slowpath) ../src/vm_insnhelper.c:2090 ruby(callable_method_entry+0x5) [0x568232d3] ../src/vm_method.c:1406 ruby(rb_callable_method_entry) ../src/vm_method.c:1413 ruby(gccct_method_search_slowpath) ../src/vm_eval.c:427 ruby(gccct_method_search+0x20f) [0x568237ef] ../src/vm_eval.c:476 ruby(opt_equality_by_mid_slowpath+0x2c) [0x5682388c] ../src/vm_insnhelper.c:2338 ruby(rb_equal+0x37) [0x566fe577] ../src/object.c:133 ruby(rb_big_eq+0x34) [0x56876ee4] ../src/bignum.c:5554 ruby(rb_int_equal+0x14) [0x566f3ed4] ../src/numeric.c:4640 ruby(rb_int_equal) ../src/numeric.c:4634 ruby(vm_call0_cfunc_with_frame+0x6d) [0x568303c2] ../src/vm_eval.c:148 ruby(vm_call0_cfunc) ../src/vm_eval.c:162 ruby(vm_call0_body) ../src/vm_eval.c:208 ruby(rb_funcallv_scope+0xd1) [0x56833971] ../src/vm_eval.c:85 ruby(RB_TEST+0x0) [0x567e8488] ../src/time.c:78 ruby(eq) ../src/time.c:78 ruby(small_vtm_sub) ../src/time.c:1523 ruby(timelocalw+0x23b) [0x567f3e9b] ../src/time.c:1593 ruby(time_s_alloc+0x0) [0x567f536b] ../src/time.c:3698 ruby(time_new_timew) ../src/time.c:2694 ruby(time_s_mktime) ../src/time.c:3698 Notes: Merged: https://github.com/ruby/ruby/pull/7650

2022-12-19Fix guess_diff typeNobuyoshi Nakada
`unsigned_time_t` has the same size as `time_t`, but it doesn't mean these types are same except for signedness. For instance, while `long` and `long long` has the same size and `time_t` is defined as the latter on 64bit OpenBSD, `unsigned_time_t` has been defined as `long`.
