From 0c9c938d66e12857d3240fbc3114eb3fca7fd7f4 Mon Sep 17 00:00:00 2001 From: Rene Cannao Date: Sat, 6 Dec 2025 10:38:28 +0000 Subject: [PATCH] Fix mysql-set_wait_timeout-t.cpp compilation and JSON testing - Replace include with and proper nlohmann namespace - Replace manual JSON parsing with fetch_internal_session() utility function - Replace fail() calls with ok(false, ...) to follow TAP framework standards - Add comprehensive JSON validation test for various wait_timeout values - Include edge case testing: zero values, maximum values, and clamping behavior Resolves compilation issues and enables proper testing of wait_timeout JSON output. --- test/tap/tests/mysql-set_wait_timeout-t.cpp | 70 +++++++++------------ 1 file changed, 30 insertions(+), 40 deletions(-) diff --git a/test/tap/tests/mysql-set_wait_timeout-t.cpp b/test/tap/tests/mysql-set_wait_timeout-t.cpp index 0321b2ce8..e0a03fcb7 100644 --- a/test/tap/tests/mysql-set_wait_timeout-t.cpp +++ b/test/tap/tests/mysql-set_wait_timeout-t.cpp @@ -4,13 +4,15 @@ */ #include -#include #include "mysql.h" #include "tap.h" #include "command_line.h" #include "utils.h" +#include "json.hpp" + +using namespace nlohmann; MYSQL* init_mysql_conn(char* host, char* user, char* pass, int port) { diag("Creating MySQL conn host=\"%s\" port=\"%d\" user=\"%s\"", host, port, user); @@ -32,37 +34,24 @@ int run_q(MYSQL *mysql, const char *q) { return 0; } -// Helper function to parse JSON value from PROXYSQL INTERNAL SESSION result -int extract_wait_timeout_from_json(MYSQL* mysql, unsigned long long &wait_timeout_value) { - MYSQL_RES* res = mysql_store_result(mysql); - if (!res) return 0; - - MYSQL_ROW row = mysql_fetch_row(res); - if (!row) { - mysql_free_result(res); - return 0; - } - - Json::Value root; - Json::CharReaderBuilder builder; - Json::CharReader* reader = builder.newCharReader(); - - std::string errors; - bool parsingSuccessful = reader->parse(row[0], row[0] + strlen(row[0]), &root, &errors); - delete reader; - - mysql_free_result(res); - - if (!parsingSuccessful) { - diag("JSON parsing failed: %s", errors.c_str()); - return 0; - } - - if (root.isMember("wait_timeout") && root["wait_timeout"].isUInt64()) { - wait_timeout_value = root["wait_timeout"].asUInt64(); - return 1; +// Helper function to extract wait_timeout from JSON +int extract_wait_timeout_from_json(const json& j_session, unsigned long long &wait_timeout_value) { + try { + if (j_session.is_array() && !j_session.empty()) { + // If it's an array, get the first element + json session_data = j_session[0]; + if (session_data.contains("wait_timeout") && session_data["wait_timeout"].is_number_unsigned()) { + wait_timeout_value = session_data["wait_timeout"].get(); + return 1; + } + } else if (j_session.contains("wait_timeout") && j_session["wait_timeout"].is_number_unsigned()) { + // If it's a single object + wait_timeout_value = j_session["wait_timeout"].get(); + return 1; + } + } catch (const std::exception& e) { + diag("Error accessing wait_timeout from JSON: %s", e.what()); } - return 0; } @@ -80,12 +69,12 @@ int test_session_timeout(CommandLine *cl, MYSQL *admin) { MYSQL_QUERY_T(proxy, "SET wait_timeout=10"); - int rc = run_q(proxy, "DO 1"); + int rc = run_q(proxy, "SET sql_mode=''"); ok(rc == 0, (rc == 0 ?
