I have yet to think of an elegant fix for that. Another thing is that at some point diff_populate_filespec() needs to have a way to discard what was cached if memory pressure gets tight, and we would want to keep this data read from the standard input. One solution would be to add a "const char *stdin_data" to diffopts and read the data from stdin when you parse the options, and have populate_filespec point at that with s->data (setting should_free and should_munmap both to 0). - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
