annotate src/http/modules/ngx_http_dav_module.c @ 7609:f609c0ac2972
Dav: added checks for chunked to body presence conditions.
These checks were missed when chunked support was introduced. And also
added an explicit error message to ngx_http_dav_copy_move_handler()
(it was missed for some reason, in contrast to DELETE and MKCOL handlers).
