Hello,
I am using LLDB 3.9 on Linux Ubuntu. I am loading a 5GiB core which is located
on Windows file share mounted on Linux via mount.cifs. I see that we
successfully allocated memory and are trying to fill it in one read.
Unfortunately pread returns 2GiB and we never check for short read here.
I think we could combine this code with previous block "#if defined
(MAX_READ_SIZE)" if we simply check for short read here (bytes_read too small)
and loop until all the buffer is filled.
Thanks,
Eugene
#ifndef _WIN32
int fd = GetDescriptor();
if (fd != kInvalidDescriptor)
{
ssize_t bytes_read = -1;
do
{
bytes_read = ::pread (fd, buf, num_bytes, offset);
} while (bytes_read < 0 && errno == EINTR);
if (bytes_read < 0)
{
num_bytes = 0;
error.SetErrorToErrno();
}
else
{
offset += bytes_read;
num_bytes = bytes_read;
}
}
