sapi_lsapi_ub_write does not return bytes written in lsapi mode

Description

sapi/litespeed/lsapi_main.c:

static size_t sapi_lsapi_ub_write(const char *str, size_t str_length)
{
    int ret;
    int remain;
    if ( lsapi_mode ) {
        ret  = LSAPI_Write( str, str_length );
        if ( ret < str_length ) {
            php_handle_aborted_connection();
            return str_length - ret;
        }
    } else {
        remain = str_length;
        while( remain > 0 ) {
            ret = write( 1, str, remain );
            if ( ret <= 0 ) {
                php_handle_aborted_connection();
                return str_length - remain;
            }
            str += ret;
            remain -= ret;
        }
    }
    return str_length;
}

It seems to me that LSAPI_Write returns the number of bytes written. If this is less than the length of the string, something went wrong. But it then returns str_length - ret, where it should return ret.

Öffne sapi/litespeed/lsapi_main.c und untersuche sapi_lsapi_ub_write. Überprüfe anschließend den Rückgabevertrag von LSAPI_Write. Die Korrektur ist vollständig, wenn der lsapi-Modus bei einem kurzen Schreibvorgang die tatsächlich geschriebene Anzahl an Bytes meldet, während die bestehende Abort-Behandlung intakt bleibt.
