> This may manifest in buggy detection of system memory, especially in 32 bit
> systems running with more than 4GB of RAM.
> Current code:
> // Returns the total size of main memory in bytes.
> inline Try<uint64_t> memory()
> {
> #ifdef __linux__
> struct sysinfo info;
> if (sysinfo(&info) != 0) {
> return Try<uint64_t>::error(strerror(errno));
> }
> return info.totalram;
> #else
> return Try<uint64_t>::error("Cannot determine the size of main memory");
> #endif
> }
> Fixed:
> // Returns the total size of main memory in bytes.
> inline Try<uint64_t> memory()
> {
> #ifdef __linux__
> struct sysinfo info;
> if (sysinfo(&info) != 0) {
> return Try<uint64_t>::error(strerror(errno));
> }
> return info.totalram * info.mem_unit;
> #else
> return Try<uint64_t>::error("Cannot determine the size of main memory");
