Related PR: #40680 Problem Summary: This pull request temporarily disables session tracking and automatic cleanup for temporary tables due to a memory leak issue involving `Env#sessionReportTimeMap` and `Env#aliveSessionSet`. The affected logic is commented out with TODO notes, and related imports are cleaned up.

Temporary table cleanup changes: * Commented out the logic in `TemporaryTableMgr.runAfterCatalogReady` that deletes temporary tables when their creating session is gone, halting automatic cleanup. ### Release note None ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [ ] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [x] No need to test or manual test.

Related PR: apache#59535 Problem Summary: The backport of apache#59535 disables orphan temporary table auto-cleanup (TemporaryTableMgr) to stop the aliveSessionSet memory leak. test_temp_table_with_restart asserts exactly that auto-cleanup behavior and would always fail now. Skip it, mirroring upstream's practice in apache#64525. ### Release note None ### Check List (For Author) - Test: No need to test (test-only change, skipping a case) - Behavior changed: No - Does this need documentation: No * [fix](temp-table) Preserve alive-session reporting for mixed-version rolling upgrade ### What problem does this PR solve? Related PR: apache#59535 Problem Summary: apache#59535 disabled the leaking session-tracking bookkeeping (Env#aliveSessionSet / Env#sessionReportTimeMap) by commenting out registerSessionInfo/refreshSession, so aliveSessionSet always stays empty. During a rolling upgrade, an old-version master FE still queries follower FEs for their alive session ids (getAllAliveSessionIds RPC) and drops temporary tables whose owning session is not reported alive after loss_conn_fe_temp_table_keep_second (default 60s). A new-version follower would report an empty list, so the old master would wrongly delete temp tables of sessions that are actually alive on the new follower. Fix: derive getAllAliveSessionIds() from the live connection registry (ExecuteEnv -> ConnectScheduler -> getConnectionMap, which covers both the MySQL protocol pool and the Arrow Flight SQL pool) instead of the always-empty aliveSessionSet. The registry always reflects real client connections and needs no register/unregister bookkeeping, so alive-session reporting stays accurate for an old-version master while the leak fix of apache#59535 remains intact (registerSessionInfo/refreshSession/TemporaryTableMgr stay commented out). ### Release note None ### Check List (For Author) - Test: Unit Test (EnvTest#testGetAllAliveSessionIds), ./build.sh --fe - Behavior changed: No - Does this need documentation: No * [fix](temp-table) Register follower-created temp tables for cleanup on disconnect ### What problem does this PR solve? Related PR: apache#59535 Problem Summary: When a client connects to a follower FE and creates a temporary table, the CREATE statement is forwarded to master FE and executed there with a proxy ConnectContext (isProxy=true). Env.registerTempTableAndSession() therefore records the temp table's inner name only in the master-side proxy session, and the original client session's dbToTempTableNamesMap on the follower stays empty. When the follower session later disconnects, times out or is killed, ConnectContext.deleteTempTable() iterates an empty map and drops nothing. apache#59535 disabled the TemporaryTableMgr background cleanup that previously collected such orphan temp tables, so temp tables created via a follower leak permanently (unbounded metadata/tablet/storage leak). Fix: after a statement is successfully forwarded to master FE (StmtExecutor.forwardToMaster), if it is a CREATE TEMPORARY TABLE (nereids CreateTableCommand or legacy CreateTableStmt), register the deterministic inner name (sessionId + sign + tableName, same as master side since the session id is forwarded) into the follower session's dbToTempTableNamesMap; if it is a forwarded DROP TABLE, remove the entry symmetrically so a later disconnect does not re-drop it. Also fix the previously dead non-master branch of ConnectContext.deleteTempTable() to qualify the forwarded DROP with the db name recorded in the map, instead of relying on the session's current database at disconnect time. ### Release note Fix the issue that temporary tables created on a follower FE are not cleaned up after the session disconnects. ### Check List (For Author) - Test: Unit Test (existing org.apache.doris.catalog.EnvTest passed); added docker regression test temp_table_p0/test_temp_table_follower_disconnect (NOT run locally, docker regression environment unavailable) - Behavior changed: Yes - temporary tables created through a follower FE connection are now dropped when the session exits, as originally intended - Does this need documentation: No --------- Co-authored-by: morrySnow <zhangwenxin@selectdb.com>
