- * setcookie (for tables only)
- * keepalive
- * chunked
- * index_rd.php porting
- * index.php auth part
- * generic var management from internet
+ *
+ * DISABLED_TO_FIX - DNS access (perform blocking dns requests, must be fixed)
+ *
+ * TEST - database connection fails after a while, check close and try PGSQL_CONNECT_FORCE_NEW.
+ * TEST - images flickering on slow windows: try to poll stream every 300 ms
+ *
+ * - configuration file management
+ * - centralize all '<script ...' incapsulation to allow multiple transport system.
+ *
+ * - manage and test cross forwarder between table and room
+ * - log_legal address fix
+ * - setcookie (for tables only and persist prefs)
+ * - 404 wrong page management
+ *
+ * TEST - unneeded garbage_time.expired access
+ * TEST - BUG: fast loop on stream index_rd_ifra page (js watchdog start without timeout corrupt counts)
+ * TEST - BUG: lurker are logged out (and remain a pending socket opened (look the spush log)
+ * TEST - BUG: logout failed (fixed with a garbage_collector wrapper at sac-a-push level
+ * TEST - garbage management
+ *
+ * DONE/FROZEN - problema con getpeer (HOSTADDR)
+ *
+ * DONE - app level keep-alive
+ * DONE - index_wr other issues
+ * DONE - from room to table
+ * DONE - from table to room
+ * DONE - chunked
+ * DONE - bug: read from a not resource handle (already closed because a new socket substitute it)
+ * DONE - partial write for normal page management
+ * DONE - index_rd_ifra: last_clean issue
+ * DONE - fwrite failed error management (select, buffer where store unsent data, and fwrite check and retry)
+ * DONE - bug: after restart index_rd.php receive from prev clients a lot of req
+ * DONE - index_wr.php::chat
+ * DONE - index_wr.php::exit
+ * DONE - index_rd.php porting
+ * DONE - generic var management from internet
+ * DONE - index.php auth part
+ * ABRT - index_wr.php::reload - reload is js-only function
