nginx.git/src/os/win32, branch release-1.28.2 nginx Win32: fixed C4319 warning with MSVC 2022 x86. 2026-02-04T17:22:23+00:00 Aleksei Bavshin a.bavshin@nginx.com 2025-12-23T18:44:13+00:00 dc50b86db8844f3c243ac374fb08beb79495f3cf The warning started to appear in Visual Studio 2022 version 17.14.21, which corresponds to the C/C++ compiler version 19.44.35221. The appropriate fix is to avoid mixing uint64_t and ngx_uint_t in an expression with bitwise operations. We can do that here because both the original shm->size value and the result of the expression are 32-bit platform words.

Silenced complaints about socket leaks on forced termination. 2024-01-29T07:29:39+00:00 Maxim Dounin mdounin@mdounin.ru 2024-01-29T07:29:39+00:00 cc4c3ee0a45ca3a2eeac2874e9199bf42560015c When graceful shutdown was requested, and then nginx was forced to do fast shutdown, it used to (incorrectly) complain about open sockets left in connections which weren't yet closed when fast shutdown was requested. Fix is to avoid complaining about open sockets when fast shutdown was requested after graceful one. Abnormal termination, if requested with the WINCH signal, can still happen though.

Win32: extended ngx_random() range to 0x7fffffff. 2023-12-09T08:38:14+00:00 J Carter jordanc.carter@outlook.com 2023-12-09T08:38:14+00:00 c0134ded9fce48f36465cb1a1adbcc52e32f8c65 rand() is used on win32. RAND_MAX is implementation defined. win32's is 0x7fff. Existing uses of ngx_random() rely upon 0x7fffffff range provided by POSIX implementations of random().

This fixes potentially incorrect cache size calculations and non-working
"min_free" when using cache in directories with non-ASCII names.

Just a drive letter might not correctly represent file system being used,
notably when using symlinks (as created by "mklink /d").  As such, instead
of trying to call GetDiskFreeSpace() with just a drive letter, we now always
use GetDiskFreeSpace() with full path.

Further, it looks like the code to use just a drive letter never worked,
since it tried to test name[2] instead of name[1] to be ':'.

This makes it possible to use temporary directories with non-ASCII characters,
either explicitly or via a prefix with non-ASCII characters in it.
