annotate src/core/ngx_sha1.h @ 6298:8f6d753c1953
Adjusted file->sys_offset after the write() syscall.
This fixes suboptimal behavior caused by surplus lseek() for sequential writes
on systems without pwrite(). A consecutive read after write might result in an
error on systems without pread() and pwrite().
Fortunately, at the moment there are no widely used systems without these
syscalls.
