It * generates a whole whack of output using bputc() and bputs(). It * also exercises start_chunk() and end_chunk() in buff.c. To use it * you should use a tool like netcat and the src/test/check_chunked * tool. Add something like this to your access.conf file: * * <Location /rndchunk> * SetHandler rndchunk * </Location> * * Then fake requests such as: * * GET /rndchunk?0,1000000 HTTP/1.1 * Host: localhost * * The first arg is the random seed, the second is the number of * "things" to do. You should try a few seeds. * * You should also edit main/buff.c and change DEFAULT_BUFSIZE (and * CHUNK_HEADER_SIZE). Small values are particularly useful for * finding bugs. Try a few different values. * * -djg */ #include "httpd.h" #include "http_protocol.h" #include "http_config.h" #include "http_main.h" #define MAX_SEGMENT 32 #define ONE_WEIGHT (256-32) static int send_rndchunk(request_rec *r) { const char *args; char *endptr; unsigned int seed; unsigned int count; int i; char buf[MAX_SEGMENT + 1]; unsigned int len; r->allowed |= (1 << M_GET); if (r->method_number != M_GET) return DECLINED; r->content_type = "text/html"; send_http_header(r); if(r->header_only) { return 0; } hard_timeout("send_rndchunk", r); if (!r->chunked) { rputs("Not chunked!", r); return 0; } args = r->args; if (!args) { error: rputs("Must include args! ... of the form <code>?seed,count</code>", r); return 0; } seed = strtol(args, &endptr, 0); if (!endptr || *endptr != ',') { goto error; } ++endptr; count = strtol(endptr, &endptr, 0); srandom(seed); for (i = 0; i < count; ++i) { len = random() % (MAX_SEGMENT + ONE_WEIGHT); if (len >= MAX_SEGMENT) { rputc((i & 1) ?
