      Description

      1. when somebody hits a semaphore and sees error message log it into "System Log" with "Error" Log Level - 0.5h
      2. add following columns to "Semaphores" table: - 0.5h
        • MainIDs - db type: text; comma-separated list of IDs
        • UserId - db type: int
        • IpAddress - db type: varchar(15)
        • Hostname - db type: varchar(255)
        • LogRequestURI - db type: varchar(255)
        • Backtrace - db type: longtext;
      3. add following setting in the "System Settings" sub-section in the "Configuration > Website > Advanced" section: - 0.5h
        • name: "SemaphoreLifetime"
        • title: "Semaphore Inactivity Timeout (seconds)"
        • default: 300 (means 5 minutes)
      4. create "adm:OnDeleteStaleSemaphores" event, that will: - 1.5h
        • get records from "Semaphores" table, where "Semaphores.Timestamp + {SemaphoreLifetime}

          > UNIX_TIMESTAMP()"

        • if none found, then exit
        • for each found record:
          • create record in "SystemLog" table (using "$this->Application->log" method) where:
            • the "setLogField" method will be used to replace "LogHostname", "LogRequestSource", "LogRequestURI", "LogUserId", "IpAddress" and "LogSessionKey" field values with one, that Semaphore has
            • the "addTrace" method will be used to add trace from semaphore
            • the "setUserData" method will be used to store: value of "MainIDs" field, semaphore creation time, semaphore removal time
            • "Log Level" would be "error"
            • "Message" would be "Stale semaphore discovered"
            • goal is to make that record look like it was created along with semaphore creation
          • delete semaphore record
        • turn "adm:OnDeleteStaleSemaphores" event into a scheduled task, that will run each 5 minutes - 0.5h
