     296Comments: 
     297 * qserv-related: 
     298  * Added db context support in proxy/Lua and qserv parser. 
     299  * Check for garbage queries in frontend so that they don't crash the system. 
     300  * Test Object-Source table joining. 
     301  * Add more error checking in parser to catch bad (though not garbage) queries. 
     302  * Accept non-lower-case functions in SQL. 
     303  * Refactor parser-driving code. 
     304  * Start stabilizing the testing code. 
     305  * Implement synthesizer for fake Source data from usnob tables. 
     306  * Increase robustness of result-merging code. 
     307  * Add db-access checks in sql parser. 
     308  * Add basic query squashing so that really early failures can avoid useless work. 
     309  * Handle errors better when query hints are missing/malformed. 
     310  * Write high-level overview of qserv. 
     311  * Add result-table specification in subqueries, and dump/transmit/reload tables instead of databases to avoid excessive overhead from creation/destruction of databases. 
     312  * Improve mutex protection on qserv master. 
     313  * Add basic objectId support in query hints. 
     314  * Switch subquery mgmt to conditions rather than polling -- shortest queries are now ~1s. 
     315  * qserv-worker: 
     316   * Fix worker to create overlap tables when subchunking. 
     317   * Some code cleanup. 
     318   * Improve error handling to pass execution errors during result signalling so that errors propagate up to xrootd. 
     319   * Improve query write-buffering.
