- GODT-1302: Change maximum resty retries from 0 to 30 - GODT-1302: Make sure we are closing GetAttachmen io.ReadCloser on error - GODT-1356: Do not use attachmentPool - it was useless anyway - GODT-1356: Increase cache watcher limit to 10min - GODT-1356: Start cache watcher right after start (do not wait first 10 min) - GODT-1356: Limit number of buildJobs (memory allocation) in BuildAndCacheMessage - Other: Pass context from job options (message builder) to fetcher (both message and attachments) - Other: BuildJob contains same function as returned buildDone (proper map locking)
