I look at the code, in find_node(), I find out node and sentinel are
NULL.
So it does not go into while loop.
350 static ngx_http_uploadprogress_node_t *
351 find_node(ngx_str_t * id, ngx_http_uploadprogress_ctx_t * ctx,
ngx_log_t * log)
352 {
353 uint32_t hash;
354 ngx_rbtree_node_t *node, *sentinel;
355 ngx_int_t rc;
356 ngx_http_uploadprogress_node_t *up;
357
358 ngx_log_debug1(NGX_LOG_DEBUG_HTTP, log, 0, "upload-progress:
find_node %V", id);
359
360 hash = ngx_crc32_short(id->data, id->len);
361
362 node = ctx->rbtree->root;
363 sentinel = ctx->rbtree->sentinel;
364
365 ngx_log_debug1(NGX_LOG_DEBUG_HTTP, log, 0, "upload-progress:
node: %V sentinel: %V", node, sentinel);
366
367 while (node != sentinel) {
368
369 ngx_log_debug1(NGX_LOG_DEBUG_HTTP, log, 0,
"upload-progress: hash: %V node->key: %V", hash, node->key);
370 if (hash < node->key) {
371
372 node = node->left;
373 continue;
374 }
375
376 if (hash > node->key) {
377 node = node->right;
378 continue;
379 }
380
381 /* hash == node->key */
382
383 do {
384
385 ngx_log_debug1(NGX_LOG_DEBUG_HTTP, log, 0,
"upload-progress: In while");
386 up = (ngx_http_uploadprogress_node_t *) node;
387
388 rc = ngx_memn2cmp(id->data, up->data, id->len, (size_t)
up->len);
389
390 if (rc == 0) {
391 ngx_log_debug0(NGX_LOG_DEBUG_HTTP, log, 0,
392 "upload-progress: found node");
393 return up;
394 }
I want to know which function to initialize node and sentinel.
