New Revision: 5047
URL: http://trac.nginx.org/nginx/changeset/5047/nginx
Log:
Merge of r4967: ngx_write_fd() and ngx_read_fd() errors handling.
The ngx_write_fd() and ngx_read_fd() functions return -1 in case of error,
so the incorrect comparison with NGX_FILE_ERROR (which is 0 on windows
platforms) might result in inaccurate error message in the error log.
Also the ngx_errno global variable is being set only if the returned value
is -1.
